The recent decline in prices seems to be more the result of an unraveling of speculative pressures than a change in underlying fundamentals. Prices had been running higher than supply/demand fundamentals would have indicated throughout the fall months as a result of rising Mideast tensions, concern over the adequacy of distillate supplies, and expectations of Iraqi supply interruptions.

7 7 Notes: Spot WTI prices broke $35 and even $36 per barrel in November as anticipated boosts to world supply from OPEC and other sources failed to find much realization in actual stocks data. The idea that stocks are still languishing at below-normal levels is particularly persuasive when one views current levels (for key consuming regions) relative to "normal" values which account for the long-term trend in OECD stocks. We believe that monthly average WTI prices will stay around $30 per barrel for the first part of 2001. This is a noticeable upward shift in our projected average prices from even a month ago. The shift reflects greater emphasis on the lack of stock builds and less emphasis on the assumption that supply from OPEC and non-OPEC suppliers may be exceeding demand by 1-2

WTI Crude Oil Prices Are Expected To Remain Relatively High Through At
5 5 Notes: As we just saw, one of the primary factors impacting gasoline price is the crude oil price. This graph shows monthly average spot West Texas Intermediate crude oil prices. Spot WTI crude oil prices broke $36 per barrel in November briefly as anticipated boosts to world supply from OPEC and other sources did not show up in actual stocks data. Crude oil prices are expected to be about $30 per barrel for the rest of this year, but note the uncertainty bands on this projection. They give an indication of how difficult it is to know what these prices are going to do. Also, EIA does not forecast volatility. This relatively flat forecast could be correct on average, with wide swings around the base line. With the EIA forecast for crude prices staying high this year,

[Find paper at ACS Publications] Abstract: Carbon-halogen bond dissociation rates for a series of aryl halide radical anions (ArX-·: X = Cl, Br) in NMP were measured at room temperature by pulse radiolysis with 10-11 s time resolution. To obtain accurate dissociation rates, care was taken to measure and correct for competing decay channels. The observed rates correlated well with activation energies computed in the gas phase by density functional (DFT) calculations. The rates did not correlate well with electron affinities or dissociation energies obtained by the same computational methods, although such

Hot water can freeze faster than cold?!?
We review the Mpemba effect, where intially hot water freezes faster than initially cold water. While the effect appears impossible at first sight, it has been seen in numerous experiments, was reported on by Aristotle, Francis Bacon, and Descartes, and has been well-known as folklore around the world. It has a rich and fascinating history, which culminates in the dramatic story of the secondary school student, Erasto Mpemba, who reintroduced the effect to the twentieth century scientific community. The phenomenon, while simple to describe, is deceptively complex, and illustrates numerous important issues about the scientific method: the role of skepticism in scientific inquiry, the influence of theory on experiment and observation, the need for precision in the statement of a scientific hypothesis, and the nature of falsifiability. We survey proposed theoretical mechanisms for the Mpemba effect, and the results of modern experiments on the phenomenon. Studies of the observation that hot water pipes are more likely to burst than cold water pipes are also described.

Ground potential rise monitor
SciTech Connect
A device and method for detecting ground potential rise (GPR) comprising positioning a first electrode and a second electrode at a distance from each other into the earth. The voltage of the first electrode and second electrode is attenuated by an attenuation factor creating an attenuated voltage. The true RMS voltage of the attenuated voltage is determined creating an attenuated true RMS voltage. The attenuated true RMS voltage is then multiplied by the attenuation factor creating a calculated true RMS voltage. If the calculated true RMS voltage is greater than a first predetermined voltage threshold, a first alarm is enabled at a local location. If user input is received at a remote location acknowledging the first alarm, a first alarm acknowledgment signal is transmitted. The first alarm acknowledgment signal is then received at which time the first alarm is disabled.

Density rise experiment on PLT
The evolution of the density profile in PLT during intense gas puffing is documented and analyzed. Measurements of the spectrum of low energy edge neutrals and of the change in central neutral density indicate that charge-exchange processes alone cannot account for the central density rise. The transient density profile changes can be reproduced numerically by a diffusivity of approx. 10/sup 4/ cm/sup 2//s, and a spatially averaged inward flow of 10/sup 3/ cm/s. These transport coefficients are 10 ..-->.. 10/sup 2/ times larger than neoclassical. The ion energy confinement is reduced, the small scale density fluctuations are increased, and runaway electrons losses are increased during the density rise.

Tests show ability of vacuum circuit breaker to interrupt fast transient recovery voltage rates of rise of transformer secondary faults
A vacuum circuit breaker demonstrated its ability to interrupt short circuits with faster than normal rates of rise of transient recovery voltage (TRV) at levels greater than those produced by most transformer secondary faults. Two recent exploratory test programs evaluated the interrupting ability of a 15kV vacuum circuit breaker containing interrupters of the rotating arc type with contacts made from a chromium-copper powder metal mixture. The interrupting conditions covered a wide range of currents from 10% to 130% of the 28kA rated short circuit current of the tested circuit breaker and a wide range of TRV rates of rise, including the relatively slow rate of rise, normally used in testing and found in most indoor circuit breaker applications, two faster rates of rise equaling and exceeding those found in a known power plant transformer secondary protection application, and the fastest rates of rise possible in the laboratory which exceed the requirements of most transformer secondary faults. These tests showed that the interrupting performance of the tested vacuum circuit breaker was unaffected by the TRV rate of rise to the fastest rates available in the test lab. Such a vacuum circuit breaker can therefore be used without TRV modifying capacitors to slow down the rate of rise provided by the power system. This ability is particularly important if analysis shows that the expected TRV from a transformer secondary fault has a fast rate of rise beyond the recognized ability of an older circuit breaker to acceptably interrupt.

Value of Faster Computation for Power Grid Operation
As a result of the grid evolution meeting the information revolution, the power grid is becoming far more complex than it used to be. How to feed data in, perform analysis, and extract information in a real-time manner is a fundamental challenge in today�s power grid operation, not to mention the significantly increased complexity in the smart grid environment. Therefore, high performance computing (HPC) becomes one of the advanced technologies used to meet the requirement of real-time operation. This paper presents benefit case studies to show the value of fast computation for operation. Two fundamental operation functions, state estimation (SE) and contingency analysis (CA), are used as examples. In contrast with today�s tools, fast SE can estimate system status in a few seconds�comparable to measurement cycles. Fast CA can solve more contingencies in a shorter period, reducing the possibility of missing critical contingencies. The benefit case study results clearly show the value of faster computation for increasing the reliability and efficiency of power system operation.

Discrete Momentum Mechanics and Faster Than Light Transition
In this work a new mechanics will be studied which is based on the hypothesis that the change of linear momentum of a particle happens as a discrete pulses. By using this hypothesis and by considering Newton's relation between energy and momentum, and the law of mass and energy conservation as a priori, the Einstein dispersion relation can be derived as a zero approximation without using Lorentz transformations. Other terms will be derived as a corrections to this relation. It will be shown that the effect of the corrections will be smaller and smaller with the increase of momentum. The work will offer an explanation of why the velocity of light seems to be constant regardless of the velocity of the source, and under which condition this will be changed. Also a prediction is made that faster than light transition could happen theoretically under certain conditions, and a nonzero mass photon can exist in nature. The work is purely classical in the sense that it doesn't involve any uncertainty relations.

Wolfe, Alexander P.
In RHIC high intensity operation, two types of pressure rise are currently of concern. The first type is at the beam injection, which seems to be caused by the electron multipacting, and the second is the one at the beam transition, where the electron cloud is not the dominant cause. The first type of pressure rise is limiting the beam intensity and the second type might affect the experiments background for very high total beam intensity. In this article, the pressure rises at RHIC are described, and preliminary study results are reported. Some of the unsettled issues and questions are raised, and possible counter measures are discussed.

But what happens when an object travels faster than the speed of light? At Jefferson Laboratory, construction is underway to upgrade the Continuous Electron Beam Accelerator Facility (CEBAF) and the CEABF Large Acceptance Spectrometer (CLAS12) at Hall B. During the experiments, the accelerator will shoot electrons at speeds faster than the speed at which light travels in the same medium, creating shock waves that emit a blue light, known as Cherenkov light -- this light is equivalent to the sonic boom. By recording data from Cherenkov light, scientists will be able to map a nucleon's three-dimensional spin.

Short rise time intense electron beam generator
DOE Patents (OSTI)
A generator for producing an intense relativistic electron beam having a subnanosecond current rise time includes a conventional generator of intense relativistic electrons feeding into a short electrically conductive drift tube including a cavity containing a working gas at a low enough pressure to prevent the input beam from significantly ionizing the working gas. Ionizing means such as a laser simultaneously ionize the entire volume of working gas in the cavity to generate an output beam having a rise time less than one nanosecond.

A logical treatment of special relativity, with and without faster-than-light observers
There are three goals of this thesis. First: to present a concise yet accessible description of basic mathematical logic and model theory. Second: to develop an axiomatization of special relativity using only two undefined predicates. Ideally, these axioms should be empirically verifiable and supported by a large body of evidence. Finally: to weaken this axiomatization so as to allow for the existence of faster-than-light observers, which are normally excluded from the theory of special relativity. The modifications to the axiom system should be as slight as possible, and should be motivated by the question: what features of the original axiom system preclude the existence of faster-than-light observers?

Rising House Prices and Monetary Policy
Abstract. It is argued that the recent rise in house prices is the biggest �nancial asset price boom in history. In this note, I look at how house prices are determined and how house price bubbles can occur. I discuss whether the recent increase in house prices is a bubble, whether monetary policy can cause a rise in the price of houses relative to other goods and what central banks should do in response to house price bubbles. Finally, I consider how central banks should take account of house prices in the price index used by central banks to measure in�ation. According to the Economist, the rise in housing prices in developed countries in the last �ve years is the biggest bubble in history, with the total value of residential properties increasing by more than $30 trillion: an amount roughly equal to to developed countries combined annual GDPs. 1 This compares with the global stockmarket boom of the late 1990s where the �ve-year increase was equal to about 80 percent of annual GDP. 2 1. How are House Prices Determined? Before proceeding with an analysis of the relationship between monetary policy and the house price boom, it is useful to consider how house prices are determined and how a house price bubble might arise. To keep matters simple, I abstract from uncertainty, depreciation and transactions costs. Consider a household deciding whether to rent or to buy a house in period t. If the household rents the house it pays the time-t rent, denoted by Q(t). If it purchases the house it pays the time-t house price, denoted by Ph (t). If it opted to purchase, rather than rent, then at the start of period t + 1 the household owns a house worth Ph (t + 1): The value to the household in period t of an amount Ph (t + 1) received in period t + 1

Changes to the utility rate template or fields cause small updates on all 29K+ utility rates on OpenEI, which takes time to process. Older versions of mediawiki and semantic mediawiki were not as efficient at handling these. Preliminary results after changing a field and tweaking job run speeds shows a ~60X improvement in speed. Changes to utility rates can now be propagated to the entire database in approximately 35 minutes - before it took more than one day. We are hopeful we will keep seeing various benefits from the upgrade process.
Paleomagnetism of Igenous Rocks from Shatsky Rise
Shatsky Rise is oceanic plateau in the northwest part of the Pacific Ocean, and the formation of Shatsky Rise is poorly known. To get a better understanding of the formation Integrated Ocean Drilling Program (IODP) Expedition 324 drilled five sites: Sites U1347 and U1348 on Tamu Massif, Site U1349 and U1350 on Ori Massif, and Site U1346. Paleomagnetic measurements of the basaltic flows recovered can give insight into the timing and paleolatitude of each site. Relating the change in principle component inclination over depth at each site to the paleosecular variation of the geomagnetic field can better constrain the timing of the eruptions. Measurements were carried out by different sources during IODP Expedition 324 and after. This study is an amalgamation of the results from Sites U1346, U1347, U1349, and U1350. Samples from each site were divided into half and demagnetized using alternating field (AF) demagnetization and thermal (TH) demagnetization. After the drilling overprint was removed most samples displayed univectorial decay in the orthogonal vector plot. AF demagnetized samples displayed a low median destructive field (MDF) behavior, 10-20 mT. Thermal demagnetized samples displayed three behaviors: a rapid decline in magnetic intensity after moderate temperature steps behavior, a linear decline in magnetic intensity behavior, and some samples displayed a small segment of self-reversal at 300�-350�. Using the Cox and Gordon (1984) method Sites U1346, U1347, and U1349 displayed very little variation in principal component inclinations over depth, implying a relatively rapid lava emplacement of 10^2-10^3 years. Site U1350 display more variation, implying a longer eruptive time frame of 10^4-10^5years. With the assumption of a normal polarity the paleolatitude estimates are -11.0� +22.2�/-21.4� for Site U1346, 11.3� 27.4�/-28.5� for Site U1347, -5.0� +20.8�/-20.6� for Site U1349 and 1.6� �7.7 � for Site U1350. The site paleolatitudes imply that Ori Massif (Sites U1350 and U1349) formed at the equator and Tamu Massif (Site U1347) and Shirshov Massif (Site U1346) formed slightly north and south of the equator respectively. All results are consistent with the interpretation that Shatsky Rise formed near the equator.

Methane level rise blamed in greenhouse effect
As scientists continue to probe effects of global warming trends and the greenhouse effect, increasing attention is being placed on the impact of methane. Last year, scientists at the University of California in Irvine found there were almost 1.7 parts per million of methane in the troposphere- 11% higher that a decade ago and climbing at 1% annually. European scientists came up with similar analyses, and the belief is that methane is currently 2.4 times higher than it has ever been in the last 160,000 years. The big challenge now is to identify the sources of the methane. About 15 to 20% can be traced to oil and gas wells, coal mining and other tapping of the gas trapped in the planet's crust. Other sources are bacteria working in tropical rain forests, burned-off clearings, etc. Cattle figure high on the list of methane generators. When domesticated herds of sheep, goats, pigs, etc. are figured, the total rises to 73 million metric tons per year- a 435% increase since 1890. Rice paddies are also rated a major source of methane. It's estimated that 115 million metric tons rise from rice paddies a year, as much as is coming from natural swamps and wetlands. When scientists added up all the published estimates of methane production, the total ranged from 400 million to 640 million metric tons a year. Estimates of how much methane the atmosphere can handle are similarly uncertain, ranging from 300 million to 650 million metric tons a year.

Coupling of Two Motor Proteins: a New Motor Can Move Faster
We study the effect of a coupling between two motor domains in highly-processive motor protein complexes. A simple stochastic discrete model, in which the two parts of the protein molecule interact through some energy potential, is presented. The exact analytical solutions for the dynamic properties of the combined motor species, such as the velocity and dispersion, are derived in terms of the properties of free individual motor domains and the interaction potential. It is shown that the coupling between the motor domains can create a more efficient motor protein that can move faster than individual particles. The results are applied to analyze the motion of helicase RecBCD molecules.

Computational Fluid Dynamics of rising droplets
The main goal of this study is to perform simulations of droplet dynamics using Truchas, a LANL-developed computational fluid dynamics (CFD) software, and compare them to a computational study of Hysing et al.[IJNMF, 2009, 60:1259]. Understanding droplet dynamics is of fundamental importance in liquid-liquid extraction, a process used in the nuclear fuel cycle to separate various components. Simulations of a single droplet rising by buoyancy are conducted in two-dimensions. Multiple parametric studies are carried out to ensure the problem set-up is optimized. An Interface Smoothing Length (ISL) study and mesh resolution study are performed to verify convergence of the calculations. ISL is a parameter for the interface curvature calculation. Further, wall effects are investigated and checked against existing correlations. The ISL study found that the optimal ISL value is 2.5{Delta}x, with {Delta}x being the mesh cell spacing. The mesh resolution study found that the optimal mesh resolution is d/h=40, for d=drop diameter and h={Delta}x. In order for wall effects on terminal velocity to be insignificant, a conservative wall width of 9d or a nonconservative wall width of 7d can be used. The percentage difference between Hysing et al.[IJNMF, 2009, 60:1259] and Truchas for the velocity profiles vary from 7.9% to 9.9%. The computed droplet velocity and interface profiles are found in agreement with the study. The CFD calculations are performed on multiple cores, using LANL's Institutional High Performance Computing.

Greenhouse effect, sea level rise, and coastal zone management
Increasing concentrations of carbon dioxide and other gases are expected to warm the earth several degrees in the next century by a mechanism known as the greenhouse effect. Such a warming could cause sea level to rise two to five feet by expanding ocean water, melting mountain glaciers, and perhaps eventually causing polar glaciers to melt and slide into the oceans. A rise in sea level of even three feet could cause substantial erosion of beaches and coastal wetlands, increased flooding, and intrusion of salt water into rivers, bays, and aquifer. Fortunately, many of the adverse consequences can be avoided by taking timely measures in anticipation of sea level rise. Nevertheless, many coastal zone managers are reluctant to take these measures until the prospect of sea level rise becomes more certain. This article examines the implications of future sea level rise and identifies anticipatory measures that may be appropriate today in spite of current uncertainties. 46 references, 4 figures, 1 table.

A faster algorithm for smoothed particle hydrodynamics with radiative transfer in the flux-limited diffusion approximation
We describe a new, faster implicit algorithm for solving the radiation hydrodynamics equations in the flux-limited diffusion approximation for smoothed particle hydrodynamics. This improves on the method elucidated in Whitehouse & Bate by using a Gauss-Seidel iterative method rather than iterating over the exchange of energy between pairs of particles. The new algorithm is typically many thousands of times faster than the old one, which will enable more complex problems to be solved. The new algorithm is tested using the same tests performed by Turner & Stone for ZEUS-2D, and repeated by Whitehouse & Bate.

Rise Time Measurement for Ultrafast X-Ray Pulses
A pump-probe scheme measures the rise time of ultrafast x-ray pulses. Conventional high speed x-ray diagnostics (x-ray streak cameras, PIN diodes, diamond PCD devices) do not provide sufficient time resolution to resolve rise times of x-ray pulses on the order of 50 fs or less as they are being produced by modern fast x-ray sources. Here, we are describing a pump-probe technique that can be employed to measure events where detector resolution is insufficient to resolve the event. The scheme utilizes a diamond plate as an x-ray transducer and a p-polarized probe beam.

The physics of the formation of magnetic active regions (ARs) is one of the most important problems in solar physics. One main class of theories suggests that ARs are the result of magnetic flux that rises from the tachocline. Time-distance helioseismology, which is based on measurements of wave propagation, promises to allow the study of the subsurface behavior of this magnetic flux. Here, we use a model for a buoyant magnetic flux concentration together with the ray approximation to show that the dominant effect on the wave propagation is expected to be from the roughly 100 m s{sup -1} retrograde flow associated with the rising flux. Using a B-spline-based method for carrying out inversions of wave travel times for flows in spherical geometry, we show that at 3 days before emergence the detection of this retrograde flow at a depth of 30 Mm should be possible with a signal-to-noise level of about 8 with a sample of 150 emerging ARs.

Faster Phase Estimation
We develop several algorithms for performing quantum phase estimation based on basic measurements and classical post-processing. We present a pedagogical review of quantum phase estimation and simulate the algorithm to numerically determine its scaling in circuit depth and width. We show that the use of purely random measurements requires a number of measurements that is optimal up to constant factors, albeit at the cost of exponential classical post-processing; the method can also be used to improve classical signal processing. We then develop a quantum algorithm for phase estimation that yields an asymptotic improvement in runtime, coming within a factor of log* of the minimum number of measurements required while still requiring only minimal classical post-processing. The corresponding quantum circuit requires asymptotically lower depth and width (number of qubits) than quantum phase estimation.

RISE: a fast-readout imager for exoplanet transit timing
By the precise timing of the low amplitude (0.005 - 0.02 magnitude) transits of exoplanets around their parent star it should be possible to infer the presence of other planetary bodies in the system down to Earth-like masses. We describe the design and construction of RISE, a fast-readout frame transfer camera for the Liverpool Telescope designed to carry out this experiment. The results of our commissioning tests are described as well as the data reduction procedure necessary. We present light curves of two objects, showing that the desired timing and photometric accuracy can be obtained providing that autoguiding is used to keep the target on the same detector pixel for the entire (typically 4 hour) observing run.

A Regenerative High-Rise Tower in Shreveport, Louisiana
Zero Net Energy Buildings are increasingly being designed and constructed in response to the demand for sustainable buildings. But, we must now go beyond merely sustaining our environment for future generations we must provide regenerative designs that restore our natural environment. This paper will document the design of a regenerative high-rise tower in Shreveport, Louisiana, which will serve as a facility to train individuals in a non-profit organization�s renewal strategies and demonstrate by example the pedagogy of regenerative design. The 16-story structure � built in the 1950s and named the Petroleum Tower, reflecting the commodity that then ruled the local economy � was vacant and asbestos-laden when given to the non-profit Community Renewal International (CRI) in 2001. In 2006, funded by a grant from the U.S. Environmental Protection Agency, workers removed the asbestos. Through a follow up grant from the U.S. Department of Energy to support the design process of a new CRI headquarters building, the University of Texas at Austin School of Architecture completed architectural design studies for the building renewal. The principles of this new design include: day lighting, envelope configuration, building integrated photovoltaic systems, green surfaces, ventilation strategies, advanced mechanical cooling systems, regenerative elevator systems, energy management systems, water harvesting, grey water systems, trigeneration systems and a combined heating, hot water and power biodiesel plant.

Predicting the solar maximum with the rising rate
The growth rate of solar activity in the early phase of a solar cycle has been known to be well correlated with the subsequent amplitude (solar maximum). It provides very useful information for a new solar cycle as its variation reflects the temporal evolution of the dynamic process of solar magnetic activities from the initial phase to the peak phase of the cycle. The correlation coefficient between the solar maximum (Rmax) and the rising rate ({\\beta}a) at {\\Delta}m months after the solar minimum (Rmin) is studied and shown to increase as the cycle progresses with an inflection point (r = 0.83) at about {\\Delta}m = 20 months. The prediction error of Rmax based on {\\beta}a is found within estimation at the 90% level of confidence and the relative prediction error will be less than 20% when {\\Delta}m \\geq 20. From the above relationship, the current cycle (24) is preliminarily predicted to peak around October 2013 with a size of Rmax =84 \\pm 33 at the 90% level of confidence.

OPEC Middle East plans for rising world demand amid uncertainty
The Middle Eastern members of the Organization of Petroleum Exporting Countries must plan for huge increases in oil production capacity yet wonder whether markets for the new output will develop as expected. With worldwide oil consumption rising and non-OPEC output likely to reach its resource limits soon, OPEC member countries face major gains in demand for their crude oil. To meet the demand growth, those with untapped resources will have to invest heavily in production capacity. Most OPEC members with such resources are in the Middle East. But financing the capacity investments remains a challenge. Some OPEC members have opened up to foreign equity participation in production projects, and others may eventually do so as financial pressures grow. That means additions to the opportunities now available to international companies in the Middle East. Uncertainties, however, hamper planning and worry OPEC. Chief among them are taxation and environmental policies of consuming-nation governments. This paper reviews these concerns and provides data on production, pricing, capital investment histories and revenues.

However, because global coverage of the oceans by the tide gauge network is highly nonuniform and the tide gauge data reveal considerable spatial variability, there has been a well-founded reluctance to interpret the observed secular sea level rise as representing a signal of global scale that might be related to the greenhouse effect. When the tide gauge data are filtered so as to remove the contribution of ongoing glacial isostatic adjustment to the local sea level trend at each location, then the individual tide gauge records reveal sharply reduced geographic scatter and suggest that there is a globally coherent signal of strength 2.4 {+-} 0.90 millimeters per year that is active in the system. This signal could constitute an indication of global climate warming.

Chevron-notched toughness of materials with rising fracture resistance curves
The effect of rising resistance curves on the fracture toughness determined from chevron-notched beam tests is estimated via a set of simple numerical calculations. It is shown that for materials with a rising resistance curve, the toughnesses determined by the peak load method and by the work of fracture method are both higher than the initiation toughness, and both depend on the sample size relative to the length over which the resistance curve increases. It is also found that the toughness based on the work of fracture is higher than that based on the peak load. Fracture toughness data obtained from tests of a nickel-alumina composite are discussed in light of the results of the numerical calculation.

Greenhouse effect and sea level rise: a challenge for this generation
These papers elaborate on how to deal with a catastrophic result of the ''greenhouse effect'' -- a global warming that could raise the sea level several feet by the end of the century. Topics of discussion include: physical impact of sea level rise, coastal geomorphic responses, climate sensitivity to increasing greenhouse gases and control of erosion. Inundation and salinity intrusion is reviewed, as well as economic analysis and planning for coastal disasters. There is a section which reviews implications for hazardous waste sites and siting in coastal floorplains.

Constraining the origin of the rising cosmic ray positron fraction with the boron-to-carbon ratio
The rapid rise in the cosmic ray positron fraction above 10 GeV, as measured by PAMELA and AMS, suggests the existence of nearby primary sources of high energy positrons, such as pulsars or annihilating/decaying dark matter. In contrast, the spectrum of secondary positrons produced through the collisions of cosmic rays in the interstellar medium is predicted to fall rapidly with energy, and thus is unable to account for the observed rise. It has been proposed, however, that secondary positrons could be produced and then accelerated in nearby supernova remnants, potentially explaining the observed rise, without the need of primary positron sources. Yet, if secondary positrons are accelerated in such shocks, other secondary cosmic ray species (such as boron nuclei, and antiprotons) will also be accelerated, leading to rises in the boron-to-carbon and antiproton-to-proton ratios. The measurements of the boron-to-carbon ratio by the PAMELA and AMS collaborations, however, show no sign of such a rise. With this new data in hand, we revisit the secondary acceleration scenario for the rising positron fraction. Assuming that the same supernova remnants accelerate both light nuclei (protons, helium) and heavier cosmic ray species, we find that no more than ~25% of the observed rise in the positron fraction can result from this mechanism (at the 95% confidence level)

The Rise and Fall of Type Ia Supernova Light Curves in the SDSS-II Supernova Survey
We analyze the rise and fall times of Type Ia supernova (SN Ia) light curves discovered by the Sloan Digital Sky Survey-II (SDSS-II) Supernova Survey. From a set of 391 light curves k-corrected to the rest-frame B and V bands, we find a smaller dispersion in the rising portion of the light curve compared to the decline. This is in qualitative agreement with computer models which predict that variations in radioactive nickel yield have less impact on the rise than on the spread of the decline rates. The differences we find in the rise and fall properties suggest that a single 'stretch' correction to the light curve phase does not properly model the range of SN Ia light curve shapes. We select a subset of 105 light curves well observed in both rise and fall portions of the light curves and develop a '2-stretch' fit algorithm which estimates the rise and fall times independently. We find the average time from explosion to B-band peak brightness is 17.38 {+-} 0.17 days, but with a spread of rise times which range from 13 days to 23 days. Our average rise time is shorter than the 19.5 days found in previous studies; this reflects both the different light curve template used and the application of the 2-stretch algorithm. The SDSS-II supernova set and the local SNe Ia with well-observed early light curves show no significant differences in their average rise-time properties. We find that slow-declining events tend to have fast rise times, but that the distribution of rise minus fall time is broad and single peaked. This distribution is in contrast to the bimodality in this parameter that was first suggested by Strovink (2007) from an analysis of a small set of local SNe Ia. We divide the SDSS-II sample in half based on the rise minus fall value, t{sub r} - t{sub f} {approx} 2 days, to search for differences in their host galaxy properties and Hubble residuals; we find no difference in host galaxy properties or Hubble residuals in our sample.

We use geomagnetic activity data to study the rise and fall over the past century of the solar wind flow speed V{sub SW}, the interplanetary magnetic field strength B, and the open solar flux F {sub S}. Our estimates include allowance for the kinematic effect of longitudinal structure in the solar wind flow speed. As well as solar cycle variations, all three parameters show a long-term rise during the first half of the 20th century followed by peaks around 1955 and 1986 and then a recent decline. Cosmogenic isotope data reveal that this constitutes a grand maximum of solar activity which began in 1920, using the definition that such grand maxima are when 25-year averages of the heliospheric modulation potential exceeds 600 MV. Extrapolating the linear declines seen in all three parameters since 1985, yields predictions that the grand maximum will end in the years 2013, 2014, or 2027 using V{sub SW}, F{sub S}, or B, respectively. These estimates are consistent with predictions based on the probability distribution of the durations of past grand solar maxima seen in cosmogenic isotope data. The data contradict any suggestions of a floor to the open solar flux: we show that the solar minimum open solar flux, kinematically corrected to allow for the excess flux effect, has halved over the past two solar cycles.

Predicting Land-Ice Retreat and Sea-Level Rise with the Community Earth System Model
Coastal stakeholders need defensible predictions of 21st century sea-level rise (SLR). IPCC assessments suggest 21st century SLR of {approx}0.5 m under aggressive emission scenarios. Semi-empirical models project SLR of {approx}1 m or more by 2100. Although some sea-level contributions are fairly well constrained by models, others are highly uncertain. Recent studies suggest a potential large contribution ({approx}0.5 m/century) from the marine-based West Antarctic Ice Sheet, linked to changes in Southern Ocean wind stress. To assess the likelihood of fast retreat of marine ice sheets, we need coupled ice-sheet/ocean models that do not yet exist (but are well under way). CESM is uniquely positioned to provide integrated, physics based sea-level predictions.

Strategy Guideline: Energy Retrofits for Low-Rise Multifamily Buildings in Cold Climates
This Strategy Guideline explains the benefits of evaluating and identifying energy efficiency retrofit measures that could be made during renovation and maintenance of multifamily buildings. It focuses on low-rise multifamily structures (three or fewer stories) in a cold climate. These benefits lie primarily in reduced energy use, lower operating and maintenance costs, improved durability of the structure, and increased occupant comfort. This guideline focuses on retrofit measures for roof repair or replacement, exterior wall repair or gut rehab, and eating system maintenance. All buildings are assumed to have a flat ceiling and a trussed roof, wood- or steel-framed exterior walls, and one or more single or staged boilers. Estimated energy savings realized from the retrofits will vary, depending on the size and condition of the building, the extent of efficiency improvements, the efficiency of the heating equipment, the cost and type of fuel, and the climate location.

Appropriate Response to Rising Fuel Prices Citizens Should Demand, �Raise My Prices Now!�
This paper evaluates policy options for responding to rising fuel prices. There is popular support for policies that minimize fuel prices through subsidies and tax reductions, but such policies harm consumers and the economy overall because they increase total fuel consumption and vehicle travel, and therefore associated costs such as traffic and parking congestion, infrastructure costs, traffic crashes, trade imbalances and pollution emissions. Fuel price reductions are an inefficient way to help low-income households; other strategies do more to increase affordability and provide other benefits. Because many transport decisions are durable, low fuel price policies are particularly harmful over the long term. This report identifies responses that maximize total benefits, including mobility management strategies that increase transport system efficiency, incentives to choose fuel efficient vehicles, and revenue-neutral tax shifts. With these policies fuel prices can significantly increase without harming consumers or the economy, while helping to achieve other planning objectives.

Analysis of the Benefits of Photovoltaic in High Rise Commercial Buildings
Energy efficient glazing is necessary to reduce heat gains or losses that contribute to the high-energy use of buildings. However, high-rise commercial buildings that use energy efficient glazing are still consumptive. To reduce their energy use further, recent studies have integrated photovoltaic glazed window systems into the building shell. To understand the relationship between photovoltaic windows, energy use and human satisfaction, this paper presents a study of the effects of photovoltaic glazed windows on the energy use of large commercial buildings and includes an assessment of the overall human satisfaction of the workers within photovoltaic glazed office spaces. A prototypical building was used to develop the base case simulations for the DOE-2 energy simulation program and the PV F-Chart photovoltaic analysis program. By substituting the appropriate variables in the base case simulation for each site, the building was simulated to evaluate the impact of the PV glazing on the building's heat loss/gain as well as the amount of electricity that could be expected from the PV. To test for human satisfaction, a survey was performed to assess the overall preference of the subjects to the office spaces using the photovoltaic glazed windows. Finally, an overall assessment of the economic and non-economic impacts is also discussed.

A substantial fraction of HVAC energy use in large commercial buildings is due to fan operation. Fan energy use depends in part on the relationship between system pressure drop and flow through the fan, which is commonly called a "system curve." As a step toward enabling better selections of air-handling system components and analyses of common energy efficiency measures such as duct static pressure reset and duct leakage sealing, this paper shows that a simple four-parameter physical model can be used to define system curves. Our model depends on the square of the fan flow, as is commonly considered. It also includes terms that account for linear-like flow resistances such as filters and coils, and for supply duct leakage when damper positions are fixed or are changed independently of static pressure or fan flow. Only two parameters are needed for systems with variable-position supply dampers (e.g., VAV box dampers modulating to control flow). For these systems, reducing or eliminating supply duct leakage does not change the system curve. The parametric system curve may be most useful when applied to field data. Non-linear techniques could be used to fit the curve to fan pressure rise and flow measurements over a range of operating conditions. During design, when measurements are unavailable, one could use duct design calculation tools instead to determine the coefficients.

The Rise and Fall of German Productivity Software Investment as the Decisive Driver *
Investments in Information and Communication Technology (ICT) are the source of the global growth resurgence that commenced in the mid 1990s. Most studies focus on broad ICT measures, or on computer hardware; here we examine the contributions of software intensive industries to productivity growth. The price of prepackaged software has been falling exponentially since the 1960s, which has led to substitutions towards software investments, and to reductions in the total cost of ICT hardware investments. We use novel German ICT investment data to show that software intensive industries have been the crucial determinant of German productivity growth since 1995. Not only did these industries contribute strongly to productivity growth, but they offset declining investments and productivities in other industries. Post 1995 other industries � investments in new equipment per worker collapsed, while software intensive industries � capital investments rose steadily to generate over half of Germany�s productivity growth by 2000�2004. We document sharply diverging productivity paths for software intensive and other industries. Post 1991, total factor productivity (TFP) declined secularly in other industries to generate a 15 % drag on German labor productivity, while TFP in software intensive industries rose steadily to contribute 35 % to German labor productivity growth by 2000�2004. Overall the results combine to paint a stark picture of rising capital per worker and TFP growth in software intensive sectors, contrasting with falling capital per worker and increasingly negative TFP growth in non software

A method is described for providing a variable output gas-fired furnace means with a constant temperature rise and efficiency where the furnace means includes burners, a blower, a thermostat and a delay timer, the method comprising the steps of: sensing the temperature in an area to be conditioned; comparing the sensed temperature to a predetermined set point; if the sensed temperature deviates from the predetermined set point by more than a predetermined amount, gas is supplied to the burners and the blower is started; determining the reference revolution per minute of the blower; determining the reference cubic feet per minute delivered by the blower; determining the manifold pressure; determining whether the furnace is in a high heat or a low heat mode of operation; determining the desired cubic feet per minute delivered by the blower for the current mode of operation; reading the actual revolution per minute of the blower; adjusting the speed of the blower motor if the actual and desired revolution per minute of the blower are not the same; determining whether the thermostat is satisfied; if the thermostat is not satisfied, returning to the step of determining the manifold pressure; and if the thermostat is satisfied, shutting off the gas and starting the delay timer.

Energy Performance and Comfort Level in High Rise and Highly Glazed Office Buildings
Thermal and visual comfort in buildings play a significant role on occupants' performance but on the other hand achieving energy savings and high comfort levels can be a quite difficult task especially in high rise buildings with highly glazed facades. Many studies suggest that the energy needed to keep the interior conditions at required comfort levels in buildings depends on several factors such as physical and optical properties of building elements, indoor and outdoor climate and behaviour of the occupants, etc. Moreover depending on the different orientation of building facade, the impact of these parameters might vary. The buildings are usually designed without paying much attention to this fact. The needs of each building zone might differ greatly and in order to achieve better indoor environment, different actions might be needed to taken considering the individual characteristics of each zone. In the proposed research the possibilities of evaluating building energy and comfort performance simultaneously taking into account the impact of facade orientation with use of whole building energy simulation tools are investigated through a case study.

under a Creative Commons License. The Cryosphere Reconstructing the glacier contribution to sea-level rise back to 1850
Abstract. We present a method to estimate the glacier contribution to sea-level rise from glacier length records. These records form the only direct evidence of glacier changes prior to 1946, when the first continuous mass-balance observations began. A globally representative length signal is calculated from 197 length records from all continents by normalisation and averaging of 14 different regions. Next, the resulting signal is calibrated with mass-balance observations for the period 1961�2000. We find that the glacier contribution to sea level rise was 5.5�1.0 cm during the period 1850�2000 and 4.5�0.7 cm during the period 1900�2000. 1

Faster Quantum Number Factoring via Circuit Synthesis
A major obstacle to implementing Shor's quantum number-factoring algorithm is the large size of modular-exponentiation circuits. We reduce this bottleneck by customizing reversible circuits for modular multiplication to individual runs of Shor's algorithm. Our circuit-synthesis procedure exploits spectral properties of multiplication operators and constructs optimized circuits from the traces of the execution of an appropriate GCD algorithm. Empirically, gate counts are reduced by 4-5 times, and circuit latency is reduced by larger factors.

Effluent streams from the Modular Caustic-Side Solvent Extraction Unit (MCU) will transfer to the tank farms and to the Defense Waste Processing Facility (DWPF). These streams will contain entrained solvent. A significant portion of the Strip Effluent (SE) pipeline (i.e., acid stream containing Isopar{reg_sign} L residues) length is within one inch of a sludge stream. Personnel envisioned the sludge stream temperature may reach 100 C during operation. The nearby SE stream may receive heat from the sludge stream and reach temperatures that may lead to flammability issues once the contents of the SE stream discharge into a larger reservoir. To this end, personnel used correlations from the literature to estimate the maximum temperature rise the SE stream may experience if the nearby sludge stream reaches boiling temperature. Several calculation methods were used to determine the temperature rise of the SE stream. One method considered a heat balance equation under steady state that employed correlation functions to estimate heat transfer rate. This method showed the maximum temperature of the acid stream (SE) may exceed 45 C when the nearby sludge stream is 80 C or higher. A second method used an effectiveness calculation used to predict the heat transfer rate in single pass heat exchanger. By envisioning the acid and sludge pipes as a parallel flow pipe-to-pipe heat exchanger, this method provides a conservative estimation of the maximum temperature rise. Assuming the contact area (i.e., the area over which the heat transfer occurs) is the whole pipe area, the results found by this method nearly matched the results found with the previous calculation method. It is recommended that the sludge stream be maintained below 80 C to minimize a flammable vapor hazard from occurring.

The intensity contrast of solar photospheric faculae and network elements II. Evolution over the rising phase of solar cycle 23
We studied the radiative properties of small magnetic elements (active region faculae and the network) during the rising phase of solar cycle 23 from 1996 to 2001, determining their contrasts as a function of heliocentric angle, magnetogram signal, and the solar cycle phase. We combined near-simultaneous full disk images of the line-of-sight magnetic field and photospheric continuum intensity provided by the MDI instrument on board the SOHO spacecraft. Sorting the magnetogram signal into different ranges allowed us to distinguish between the contrast of different magnetic structures. We find that the contrast center-to-limb variation (CLV) of these small magnetic elements is independent of time with a 10% precision, when measured during the rising phase of solar cycle 23. A 2-dimensional empirical expression for the contrast of photospheric features as a function of both the position on the disk and the averaged magnetic field strength was determined, showing its validity through the studied time period. A study of the relationship between magnetogram signal and the peak contrasts shows that the intrinsic contrast (maximum contrast per unit of magnetic flux) of network flux tubes is higher than that of active region faculae during the solar cycle.

Final Report on "Rising CO2 and Long-term Carbon Storage in Terrestrial Ecosystems: An Empirical Carbon Budget Validation"
The primary goal of this report is to report the results of Grant DE-FG02-97ER62458, which began in 1997 as Grant DOE-98-59-MP-4 funded through the TECO program. However, this project has a longer history because DOE also funded this study from its inception in 1985 through 1997. The original grant was focused on plant responses to elevated CO2 in an intact ecosystem, while the latter grant was focused on belowground responses. Here we summarize the major findings across the 25 years this study has operated, and note that the experiment will continue to run through 2020 with NSF support. The major conclusions of the study to date are: (1 Elevated CO2 stimulated plant productivity in the C3 plant community by ~30% during the 25 year study. The magnitude of the increase in productivity varied interannually and was sometime absent altogether. There is some evidence of down-regulation at the ecosystem level across the 25 year record that may be due to interactions with other factors such as sea-level rise or long-term changes in N supply; (2) Elevated CO2 stimulated C4 productivity by <10%, perhaps due to more efficient water use, but C3 plants at elevated CO2 did not displace C4 plants as predicted; (3) Increased primary production caused a general stimulation of microbial processes, but there were both increases and decreases in activity depending on the specific organisms considered. An increase in methanogenesis and methane emissions implies elevated CO2 may amplify radiative forcing in the case of wetland ecosystems; (4) Elevated CO2 stimulated soil carbon sequestration in the form of an increase in elevation. The increase in elevation is 50-100% of the increase in net ecosystem production caused by elevated CO2 (still under analysis). The increase in soil elevation suggests the elevated CO2 may have a positive outcome for the ability of coastal wetlands to persist despite accelerated sea level rise; (5) Crossing elevated CO2 with elevated N causes the elevated CO2 effect to diminish, with consequences for change in soil elevation.

Evaluation on Cooling Energy Load with Varied Envelope Design for High-Rise Residential Buildings in Malaysia
With the development of the economy in the recent years, Malaysia is maintaining a high economic growth and therefore, its energy consumption increases dramatically. Residential buildings are characterized by being envelope-load dominated buildings, hence are greatly influenced by the outside climatic conditions. Due to the hot humid climate of Malaysia, air conditioning system accounts for more than 45% of the total electricity used in the residential sector which is required to remove substantial amount of gained heat due to poor thermal envelope performance. This paper uses Ecotect software to analyze the impact of building envelope design on energy cooling load for residential building in Penang, Malaysia, which include area ratio of window to floor, exterior wall thermal insulation, and several kinds of shading system. This paper describes an integrated passive design approach to reduce the cooling requirement for high-rise apartments through an improved building envelope design. Comparing with the other passive strategies investigated in this paper, the results indicated that exterior wall thermal insulation is the best strategy to decrease both annual cooling energy load and peak cooling load which achieved a reduction of 10.2% and 26.3% respectively. However, the other passive strategies applied also have some marginal effect on decreasing the cooling load.

Measurement of rising R-curve behavior in toughened silicon nitride by stable crack propagation in bending
A simple procedure for measuring the R-curve properties of ceramics by a stable fracture test in three-point bending is described. As a typical case, data are displayed for a Si{sub 3}N{sub 4} material toughened by the presence of acicular grains in situ grown during the sintering process. The fracture mechanics specimen was a single-edge double-notched beam (SEDNB), whose notch was sharpened to a radius of < 10 {micro}m in order to reduce the amount of elastic energy stored at its root prior to crack extension. Furthermore, a stabilizer, specially designed for the bending geometry, was used to control crack stability. During stable extension, the crack could be easily arrested at selected locations of the load-displacement curve, the load quickly released, and the stable crack extension directly measured by the die-penetration technique. The crack resistance, K{sub R}, of the material was calculated from the measured crack extent and the onset load value before unloading. This method enabled them to precisely monitor the critical load value at which the load-displacement curve deviated from linear behavior, as well as crack extensions from a few tens of micrometers to about 1 mm. As an application of this method, the fracture resistance of a Si{sub 3}N{sub 4} material with rising R-curve behavior was measured and found to increase from about 5.5 to 9.0 MPa {center_dot} m{sup 1/2} within a 0.8-mm extension.

Ground potential rise characteristics of urban step-down substations fed by power cables - A practical example
This paper shows some special ground potential rise characteristics of substations fed by power cables. These characteristics were detected during the study of the interconnected ground system of 14 step-down urban substations fed by the 138 kV underground cable network serving the South Zone of Rio de Janeiro city in Brazil. As this type of system is very common in large cities, the subject can be of general interest for the industry. It was verified that when a fault occurs at a ''cable substation'' (a substation fed exclusively by power cables), almost no ground potential effects were detected at the faulted substation or at the other ''cable substations'' of the 138 kV network. However, high values of ground potential occurred at the ''transition substations'' (substations in which the power cables are connected to overhead 138 kV transmission lines, with steel groundwires). That ground potential was enough to produce shocks and equipment damage in certain ''transition substations''. It was verified that this problem has no relation with potential transfer. The paper shows also that the utilization of overhead lines with ACSR groundwires on the initial spans closer to the ''transition substation'' would be enough to avoid the problem. Even if the ACSR conductor is used only at the initial section of one of the lines, a reduction of the problem would be obtained. The paper shows also that the utilization of ACSR ground-wires near the ''transition substations'' contributes to reduce the amount of the copper necessary to control step, touch and mess potentials in these substations. Additional mitigation procedures are also examined in the paper.

The increasing abundance of passive 'red-sequence' galaxies since z {approx} 1-2 is mirrored by a coincident rise in the number of galaxies with spheroidal morphologies. In this paper, however, we show in detail, that, the correspondence between galaxy morphology and color is not perfect, providing insight into the physical origin of this evolution. Using the COSMOS survey, we study a significant population of red-sequence galaxies with disk-like morphologies. These passive disks typically have Sa-Sb morphological types with large bulges, but they are not confined to dense environments. They represent nearly one-half of all red-sequence galaxies and dominate at lower masses ({approx}passive disks with M {sub *} {approx}passive disk population has declined since z {approx} 1, likely because they transform into spheroidals. Based on these trends, we estimate that as much as 60% of galaxies transitioning onto the red sequence evolve through a passive disk phase. The origin of passive disks therefore has broad implications for our understanding of how star formation shuts down. Because passive disks tend to be more bulge-dominated than their star-forming counterparts, a simple fading of blue disks does not fully explain their origin. We explore the strengths and weaknesses of several more sophisticated explanations, including environmental effects, internal stabilization, and disk regrowth during gas-rich mergers. While previous work has sought to explain color and morphological transformations with a single process, these observations open the way to new insight by highlighting the fact that galaxy evolution may actually proceed through several separate stages.

THE RISE AND FALL OF THE STAR FORMATION HISTORIES OF BLUE GALAXIES AT REDSHIFTS 0.2 < z < 1.4
Popular cosmological scenarios predict that galaxies form hierarchically from the merger of many progenitors, each with their own unique star formation history (SFH). We use a sophisticated approach to constrain the SFHs of 4517 blue (presumably star-forming) galaxies with spectroscopic redshifts in the range 0.2 < z < 1.4 from the All-Wavelength Extended Groth Strip International Survey. This consists in the Bayesian analysis of the observed galaxy spectral energy distributions with a comprehensive library of synthetic spectra assembled using realistic, hierarchical star formation, and chemical enrichment histories from cosmological simulations. We constrain the SFH of each galaxy in our sample by comparing the observed fluxes in the B, R, I, and K{sub s} bands and rest-frame optical emission-line luminosities with those of one million model spectral energy distributions. We explore the dependence of the resulting SFHs on galaxy stellar mass and redshift. We find that the average SFHs of high-mass galaxies rise and fall in a roughly symmetric bell-shaped manner, while those of low-mass galaxies rise progressively in time, consistent with the typically stronger activity of star formation in low-mass compared to high-mass galaxies. For galaxies of all masses, the star formation activity rises more rapidly at high than at low redshift. These findings imply that the standard approximation of exponentially declining SFHs widely used to interpret observed galaxy spectral energy distributions may not be appropriate to constrain the physical parameters of star-forming galaxies at intermediate redshifts.

The Technical and Economical Analysis of a Centralized Air-Conditioning System with Cold Storage Refrigeration in High-Rise Residential Buildings
In recent years, the application of a centralized air-conditioning system (CACS) with cold storage refrigeration in high-rise residential buildings has gradually increased. Due to the large difference between civil residential buildings and commercial buildings, characteristics such as the cooling load in summer and the storey height must be considered in the design of the air-conditioning system, and the cold storage equipment and the cold supplying means must be properly selected. The option of establishing centralized air-conditioning equipment with cold storage and supplying unified cold in high-rise residential buildings is analyzed objectively with technical and economical methods in this paper. It is not true that the option of supplying unified cold can save energy all the time. CACS with cold storage will not always be economical. Based on a 27-floor building, the running costs in summer and the first costs are both compared between CACS with and without cold storage refrigeration. The cold storage method selected will significantly impact the residents.

Evaluation of an Absorption Heat Pump to Mitigate Plant Capacity Reduction Due to Ambient Temperature Rise for an Air-Cooled Ammonia and Water Cycle: Preprint
DOE Green Energy (OSTI)
Air-cooled geothermal plants suffer substantial decreases in generating capacity at increased ambient temperatures. As the ambient temperature rises by 50 F above a design value of 50 F, at low brine-resource temperatures, the decrease in generating capacity can be more than 50%. This decrease is caused primarily by increased condenser pressure. Using mixed-working fluids has recently drawn considerable attention for use in power cycles. Such cycles are more readily amenable to use of absorption ''heat pumps.'' For a system that uses ammonia and water as the mixed-working fluid, this paper evaluates using an absorption heat pump to reduce condenser backpressure. At high ambient temperatures, part of the turbine exhaust vapor is absorbed into a circulating mixed stream in an absorber in series with the main condenser. This steam is pumped up to a higher pressure and heated to strip the excess vapor, which is recondensed using an additional air-cooled condenser. The operating conditions are chosen to reconstitute this condensate back to the same concentration as drawn from the original system. We analyzed two power plants of nominal 1-megawatt capacity. The design resource temperatures were 250 F and 300 F. Ambient temperature was allowed to rise from a design value of 50 F to 100 F. The analyses indicate that using an absorption heat pump is feasible. For the 300 F resource, an increased brine flow of 30% resulted in a net power increase of 21%. For the 250 F resource, the increase was smaller. However, these results are highly plant- and equipment-specific because evaluations must be carried out at off-design conditions for the condenser. Such studies should be carried out for specific power plants that suffer most from increased ambient temperatures.

The manufacture of thermally stable diamond (TSP) cutters for drill bits used in petroleum drilling requires the brazing of two dissimilar materials--TSP diamond and tungsten carbide. The ENDURUS{trademark} thermally stable diamond cutter developed by Technology International, Inc. exhibits (1) high attachment (shear) strength, exceeding 345 MPa (50,000 psi), (2) TSP diamond impact strength increased by 36%, (3) prevents TSP fracture when drilling hard rock, and (4) maintains a sharp edge when drilling hard and abrasive rock. A novel microwave brazing (MWB) method for joining dissimilar materials has been developed. A conventional braze filler metal is combined with microwave heating which minimizes thermal residual stress between materials with dissimilar coefficients of thermal expansion. The process results in preferential heating of the lower thermal expansion diamond material, thus providing the ability to match the thermal expansion of the dissimilar material pair. Methods for brazing with both conventional and exothermic braze filler metals have been developed. Finite element modeling (FEM) assisted in the fabrication of TSP cutters controllable thermal residual stress and high shear attachment strength. Further, a unique cutter design for absorbing shock, the densification of otherwise porous TSP diamond for increased mechanical strength, and diamond ion implantation for increased diamond fracture resistance resulted in successful drill bit tests.

Far East LPG sales will grow faster than in West
LPG sales through 2010 in regions east of the Suez Canal (East of Suez) will grow at more than twice those in regions west of the canal. East-of-Suez sales will grow at more than 4.0%/year, compared to slightly less than 2.0%/year growth in sales West of Suez. East-of-Suez sales will reach 92 million tons/year (tpy) by 2010, accounting for 39% of the worldwide total. This share was 31% in1995 and only 27% in 1990. LPG sales worldwide will reach 192 million tons in 2000 and 243 million tpy by 2010. In 1995, they were 163 million tons. These are some of the major conclusions of a recent study by Frank R. Spadine, Christine Kozar, and Rudy Clark of New York City-based consultant Poten and Partners Inc. Details of the study are in the fall report ``World Trade in LPG 1990--2010``.

Uranium: Prices, rise, then fall
Uranium prices hit eight-year highs in both market tiers, $16.60/lb U{sub 3}O{sub 8} for non-former Soviet Union (FSU) origin and $15.50 for FSU origin during mid 1996. However, they declined to $14.70 and $13.90, respectively, by the end of the year. Increased uranium prices continue to encourage new production and restarts of production facilities presently on standby. Australia scrapped its {open_quotes}three-mine{close_quotes} policy following the ouster of the Labor party in a March election. The move opens the way for increasing competition with Canada`s low-cost producers. Other events in the industry during 1996 that have current or potential impacts on the market include: approval of legislation outlining the ground rules for privatization of the US Enrichment Corp. (USEC) and the subsequent sales of converted Russian highly enriched uranium (HEU) from its nuclear weapons program, announcement of sales plans for converted US HEU and other surplus material through either the Department of Energy or USEC, and continuation of quotas for uranium from the FSU in the United States and Europe. In Canada, permitting activities continued on the Cigar Lake and McArthur River projects; and construction commenced on the McClean Lake mill.

The impact of rising energy prices on household energy consumption and expenditure patterns: The Persian Gulf crisis as a case example
The Iraqi invasion of Kuwait and the subsequent war between Iraq and an international alliance led by the United States triggered immediate increases in world oil prices. Increases in world petroleum prices and in US petroleum imports resulted in higher petroleum prices for US customers. In this report, the effects of the Persian Gulf War and its aftermath are used to demonstrate the potential impacts of petroleum price changes on majority, black, and Hispanic households, as well as on poor and nonpoor households. The analysis is done by using the Minority Energy Assessment Model developed by Argonne National Laboratory for the US Department of Energy (DOE). The differential impacts of these price increases and fluctuations on poor and minority households raise significant issues for a variety of government agencies, including DOE. Although the Persian Gulf crisis is now over and world oil prices have returned to their prewar levels, the differential impacts of rising energy prices on poor and minority households as a result of any future crisis in the world oil market remains a significant long-term issue.

Measurement of radio wave reflection due to temperature rising from rock salt and ice irradiated by an electron beam for an ultra-high-energy neutrino detector
An ultra-high-energy neutrino (UHE{nu}) gives temperature rise along the hadronic and electromagnetic shower when it enters into rock salt or ice. Permittivities of them arise with respect the temperatures at ionization processes of the UHE{nu} shower. It is expected by Fresnel's formula that radio wave reflects at the irregularity of the permittivity in the medium. We had found the radio wave reflection effect in rock salt. The reflection effect and long attenuation length of radio wave in rock salt and ice would yield a new UHE{nu} detection method. An experiment for ice was performed to study the reflection effect. A coaxial tube was filled with rock salt powder or ice. Open end of the coaxial tube was irradiated by a 2 MeV electron beam. Radio wave of 435 MHz was introduced to the coaxial tube. We measured the reflection wave from the open end. We found the radio wave reflection effect due to electron beam irradiation in ice as well as in rock salt.

EIA - Annual Energy Outlook 2012 Early Release
Prices Prices Crude Oil figure dataPrices for crude oil3 in 2011 remained generally in a range between $85 and $110 per barrel. In 2011, WTI prices were lower than Brent prices because of pipeline capacity constraints that prevented complete arbitrage between WTI and Brent prices. Real imported sweet crude oil prices (2010 dollars) in the AEO2012 Reference case rise to $120 per barrel in 2016 (Figure 5) as pipeline capacity from Cushing, Oklahoma, to the Gulf Coast increases, the world economy recovers, and global demand grows more rapidly than the available supplies of liquids from producers outside the Organization of the Petroleum Exporting Countries (OPEC). In 2035, the average real price of crude oil in the Reference case is about $145 per barrel in 2010 dollars, or about $230 per barrel in nominal dollars.
Short Term Energy Outlook ,November 2002
November 2002 November 2002 1 Short-Term Energy Outlook November 2002 Overview World Oil Markets: During the past 3-4 months, OPEC 10 production has risen more quickly than projected, thus reducing upward pressure on prices. More specifically, while the West Texas Intermediate (WTI) crude oil spot price averaged $28.84 in October, about $6.70 per barrel above the year-ago level (Figure 1), the WTI average price for fourth quarter 2002 is now projected to soften to $28.20, which is about $2 per barrel below our fourth-quarter projection from last month. Meanwhile, OECD inventory levels, which are now approaching 5 -year lows, should begin to rise over the next few months as additional supplies reach markets, and return to the middle of their observed range by spring.
Short-Term Energy Outlook April 2002 Overview World Oil Markets: Average crude oil prices moved up strongly in March, rising nearly $4 from the average February level to $24.50 per barrel for West Texas Intermediate (WTI). A stronger sentiment on the side of OPEC production discipline, a growing sense by the market that economic growth may accelerate more rapidly than previously thought, and continued uncertainty surrounding tensions in the Middle East have elevated near-term prices above previous expectations and have caused us to raise expected average WTI prices for 2002 by about $2 per barrel from last month's projected $22.80. Continued strong compliance by OPEC producers to meet current quotas through the second quarter of this year and continued momentum toward economic
July 2003 July 2003 1 Short-Term Energy Outlook July 2003 Overview World Oil Markets. The average West Texas Intermediate (WTI) crude oil price for June was up by about $2.50 per barrel from the May average, in part because OECD oil inventories remain low by historical standards. Oil prices are not likely to fall significantly until commercial inventories rise to levels observed in recent years. EIA's Outlook is for prices to remain firm throughout the rest of 2003 (in the $29- $30 per barrel range for WTI) then gradually slide toward $26 per barrel by the end of 2004 as Iraqi oil exports return to near pre-war levels (Figure1).

7 7 1 November 2007 Short-Term Energy Outlook November 6, 2007 Release Highlights Global oil markets will likely remain stretched, as world oil demand has continued to grow much faster than oil supply outside of the Organization of the Petroleum Exporting Countries (OPEC), putting pressure on OPEC and inventories to bridge the gap. Additional fundamental factors contributing to price volatility include ongoing geopolitical risks, OECD inventory tightness, and worldwide refining bottlenecks. As a consequence, crude oil prices are expected to remain high and volatile. (See this month's supplemental report, Why are oil prices so high?). This situation has resulted in West Texas Intermediate (WTI) crude oil prices

Nuclear steam-generator transplant total rises
Several utilities with pressurized water reactors (PWRs) are replacing leaking and corroded steam generators. Over half the PWRs face corrosion problems that will cost $50 million to $100 million per unit to correct. An alternative approach of installing new tube sleeves has only had one application. Corrosion prevention still eludes utilities, whose problems differ. Westinghouse units were the first to experience corrosion problems because they have almost all operated for a decade or more. Some advances in condenser and steam-generator technology should extend the component life of younger units, and some leaking PWR tubes can be plugged. Operating differences may explain why PWRs have operated for over 20 years on submarines using phosphate water chemistry, while the use of de-aerators in the secondary-systems of foreign PWRs may explain their better performance. Among the corrective steps recommended by Stone and Webster are tighter chemistry control, better plant layup practices, revamping secondary-system hardware, condensate polishing, and de-aerators. Research continues to find the long-term preventative. 2 tables. (DCK)

Since it is impractical to wait 40,000 hours for durability results, it is critical to learn as much information as possible in as short a time period as possible to determine if an MEA sample will survive past its lifetime target. Consequently, 3M has utilized accelerated testing and statistical lifetime modeling tools to develop a methodology for evaluating MEA lifetime. Construction and implementation of a multi-cell test stand have allowed for multiple accelerated tests and stronger statistical data for learning about durability.

Can a computer be "pushed" to perform faster-than-light?
We propose to "boost" the speed of communication and computation by immersing the computing environment into a medium whose index of refraction is smaller than one, thereby trespassing the speed-of-light barrier.

The pixel purity index (PPI) algorithm proposed by Boardman, et al.1 identifies potential endmember pixels in multispectral imagery. The algorithm generates a large number of skewers (unit vectors in random directions), and then computes the dot product of each skewer with each pixel. The PPI is incremented for those pixels associated with the extreme values of the dot products. A small number of pixels (a subset of those with the largest PPI values) are selected as pure and the rest of the pixels in the image are expressed as linear mixtures of these pure endmembers. This provides a convenient and physically-motivated decomposition of the image in terms of a relatively few components. We report on a variant of the PPI algorithm in which blocks of B skewers are considered at a time. From the computation of B dot products, one can produce a much larger set of derived dot products that are associated with skewers that are linear combinations of the original B skewers. Since the derived dot products involve only scalar operations, instead of full vector dot products, they can be very cheaply computed. We will also discuss a hardware implementation on a field programmable gate array (FPGA) processor both of the original PPI algorithm and of the block-skewer approach. We will furthermore discuss the use of fast PPI as a front-end to more sophisticated algorithms for selecting the actual endmembers.

Spot Distillate & Crude Oil Prices
mid-January, 2000. WTI crude oil price rose about $17 per mid-January, 2000. WTI crude oil price rose about $17 per barrel or 40 cents per gallon from its low point in mid February 1999 to January 17, 2000. Over this same time period, New York Harbor spot heating oil had risen about 42 cents per gallon, reflecting both the crude price rise and the beginning of a return to a more usual seasonal spread over the price of crude oil. The week ending January 21, distillate spot prices in the Northeast spiked dramatically to record levels, closing on Friday at $1.26 per gallon -- up 50 cents from the prior week. Gulf Coast prices were not spiking, but were probably pulled higher as the New York Harbor market began to draw on product from other areas. They closed at 83 cents per gallon, an increase of 11 cents from the prior Friday. Crude oil had risen about 4 cents from

The Price of Neutrino Superluminality continues to rise
We revisit the model building challenges that one faces when trying to reconcile the OPERA claim of neutrino superluminality with other observational constraints. The severity of the supernova bound and of the kinematical constraints of Cohen-Glashow type lead us to focus on scenarios where all types of particles are superluminal inside matter. In contrast to the Dvali-Vikman proposal, this matter effect needs to be very short-ranged to avoid constraints from experiments on the Earth's surface in low-density environments. Due to this short range, the interaction underlying such a matter effect would have to be far stronger than permitted by fifth-force bounds. As a conceivable way out we suggest to make the matter effect "binary", i.e., dense matter does not directly trigger superluminality, but merely induces the transition to a different phase of some weakly coupled hidden sector. This phase exhibits spontaneous Lorentz violation or at least a stronger than usual mediation of some residual Lorentz violation to all matter. The effect has not been observed before since we have never before been able to measure the velocity of high-energy particles in dense matter with sufficient precision.

Barnett shale rising star in Fort Worth basin
The Mississippian-age Barnett shale of the Fort Worth basin, North Texas, has emerged as a new and active natural gas play. Natural gas production from the Barnett shale at Newark East field in Denton and Wise counties, Texas, has reached 80 MMcfd from more than 300 wells. However, very little publicly available information exists on resource potential and actual well performance. The US Geological Survey 1995 National Assessment of US Oil and Gas Resources categorized the Mississippian Barnett shale play (play number 4503) as an unconventional gas play but did not quantitatively assess this resource. This article, which expands upon a recent USGS open-file resource assessment report, provides an updated look at the Barnett shale and sets forth a new quantitative assessment for the play.

Moisture Control Handbook: New, low-rise, residential construction
Moisture problems are prevalent all over North America, almost independent of climate. They are viewed as one of the single largest factors limiting the useful service life of a building. Elevated levels of moisture in buildings also can lead to serious health effects for occupants. Until recently, very little consensus on moisture control existed in the building community. The information available was typically incomplete, contradictory, usually limited to specific regions, and in many cases misleading. A need to develop a document which presented the issues relating to moisture from a building science or ``systems`` approach existed. This handbook attempts to fill that need and illustrates that energy-efficient, tight envelope design is clearly part of the solution to healthy buildings when interior relative humidity, temperature, and pressure are controlled simultaneously. The first three chapters of the handbook present the basic principles of moisture problems and solutions in buildings. Chapter 1 -- Mold, Mildew, and Condensation, examines surface moisture problems. Chapter 2 -- Moisture Movement, examines how building assemblies get wet from both the exterior and interior. Chapter 3 -- Wetting and Drying of Building Assemblies, introduces the concepts of acceptable performance, moisture balance, and the redistribution of moisture within building assemblies. Chapters 4 through 6 apply the concepts outlined in the previous chapters and present specific moisture control practices for three basic US climate zones. The advantages and disadvantages of several wall, foundation, and roof assemblies are discussed for each climate zone.

Marine construction is on the rise but prices remain low
The offshore construction industry is coming out of the worldwide depression. The North Sea is coming back, the Gulf Mexico is making a comeback, there is work offshore India, development offshore California is helping, and Pemex is again ordering platforms. The best market in the world is still the Gulf of Mexico, and as the rig count increases, construction contractors will begin to feel the upswing. Derrick barges are finding a moderate amount of work; however, the rates are still depressed. The new source of business for the Gulf of Mexico will be oil discoveries in water depths of 1000-1500 ft. The fabrication of these platforms will be limited to the larger fabricators, but the structures are of such size they will take up capacity, and this will help the smaller fabricators as well.

Contemporary cowboy culture and the rise of American postmodern solidarity
In this dissertation, I build on contemporary theoretical perspectives to interpret characteristics of contemporary cowboy culture. Specifically, I target the image of the cowboy in relation to solidarity. I assume that contemporary cowboy culture is an illusion or simulacra of something, something maybe once authentic. Now, it is built around language games, illusion, image and many other postmodern phenomena. Even so, in this work I explore how postmodernism is useful, which many are hesitant to do. This is a new twist or at least an interesting study in contrast to the enlightenment project. I rely heavily on theoretical discussion, qualitative analysis, participant observation and interpretive interactionism to accomplish this study and engage this culture. I integrate this approach into the continuing question about progress and the relationship between postmodernism and modernism, which is characterized here by McDonaldization. I find contemporary society provides opportunities to celebrate the benefits and development of postmodern social bonding. As a result, postmodernism, characterized by chaos, contradiction, and especially illusion is found to actually create solidarity and allow for Jungian rebirth of something authentic.

Falling House Prices and Rising Time on the Market
Much of the current trouble in the housing market has been attributed to the fact that house price appreciation�strong for many years�is finally slowing; indeed, in many markets now, house prices are falling.The mere fact that falling house prices are considered newsworthy is interesting in its own right. In other asset markets, such as the stock and bond markets, prices routinely fluctuate up and down every day. In this Economic Letter I argue that the main reason for this difference reflects differences in the liquidity of houses and financial assets as investments. I review the ways in which residential real estate prices and liquidity vary over time and over different states of the economy, discuss the implications of this price and liquidity behavior

Europe's cross-border gas trade on the rise
Europe is poised for more growth in the gas industry that is certain to expand international gas trade into the next century. In the affluent societies of western Europe, gas growth will be fueled by an increasing public perception that it is the least environmentally harmful of fossil fuels. That factor is helping boost natural gas and LNG trade in many parts of the world. Gas will continue to penetrate the European residential market, but the biggest growth will occur in the industrial use, particularly for electrical power generation. The European Community has belatedly lifted restrictions on the use of a gas as a fuel for power generation. That, combined with the greater efficiency of cogeneration systems, is likely to set off a 100% increase in Europe's gas fueled power generation capacity in the first 5 years of 1990s.

Dilation x-ray imager a new/faster gated x-ray imager for the NIF
As the yield on implosion shots increases it is expected that the peak x-ray emission reduces to a duration with a FWHM as short as 20 ps for {approx}7 Multiplication-Sign 10{sup 18} neutron yield. However, the temporal resolution of currently used gated x-ray imagers on the NIF is 40-100 ps. We discuss the benefits of the higher temporal resolution for the NIF and present performance measurements for dilation x-ray imager, which utilizes pulse-dilation technology [T. J. Hilsabeck et al., Rev. Sci. Instrum. 81, 10E317 (2010)] to achieve x-ray imaging with temporal gate times below 10 ps. The measurements were conducted using the COMET laser, which is part of the Jupiter Laser Facility at the Lawrence Livermore National Laboratory.

The effect of slightly faster strain rates and internal hydrogen on uranium-0. 8 weight percent titanium alloy mechanical properties
Mechanical testing of uranium-0.8 wt % titanium (U-0.8 wt % Ti) alloys can affect the outcome of mechanical properties, primarily ductility, by varying the crosshead velocity, which changes the strain rate. However, most specifications that govern mechanical properties of this alloy reference ASTM E-8, which limits the speed to 0.5 in./in. of gage length per minute. Our current procedure for testing U-0.8 Ti is not at the maximum speed permitted in ASTM E-8, so an experiment was designed to evaluate the effect of maximizing the crosshead velocity per ASTM E-8. In order to create a fair assessment, tensile specimens were prepared that were low in internal hydrogen (0.02 ppM) and higher in internal hydrogen (0.36 ppM). External hydrogen effects were minimized by testing in a controlled environment that contained less than 10% relative humidity. Test results showed that for the low hydrogen test group, increasing the crosshead velocity caused a significant increase in reduction in area (RA), but not in elongation. For the higher hydrogen test group, increasing the speed resulted in a significant increase in RA and an increase, though not statistically significant, in elongation. Of equal importance was an observation that strongly suggests a correlation between material defects, like inclusion clusters, and higher hydrogen content, especially at the slower strain rate that would explain the erratic behavior in ductile properties associated with this alloy. As a result of this study, increasing the crosshead velocity to 0.32 in./min is recommended for mechanical testing of U-0.8 Ti alloys. 9 refs., 4 figs., 5 tabs.

Short Term Energy Outlook Short Term Energy Outlook 1 STEO Supplement: Why are oil prices so high? During most of the 1990s, the West Texas Intermediate (WTI) crude oil price averaged close to $20 per barrel, before plunging to almost $10 per barrel in late 1998 as a result of the Asian financial crisis slowing demand growth while extra supply from Iraq was entering the market for the first time since the Gulf War. Subsequently, as Organization of Petroleum Exporting Countries (OPEC) producers more closely adhered to a coordinated production quota and reduced output, crude oil prices not only recovered, but increased to about $30 per barrel as demand grew as Asian economies recovered. The most recent increase in crude oil prices began in 2004, when they almost doubled from 2003 levels, rising from about $30 per barrel at the end

This one predicts monthly average WTI price as a function of OECD total petroleum stock deviations from the normal levels . The graph shows the model as it begins predicting prices in 1992. It shows how well the model has predicted not only the direction, but the magnitude of prices over this 8+ year period. While the model is simple and not perfect, it does predict the overall trends and, in particular, the recent rise in prices. It also shows that prices may have over-shot the fundamental balance for a while -- at least partially due to speculative concerns over Mideast tensions, winter supply adequacy, and Iraq's export policies. Prices now seem to be correcting, and may even undershoot briefly

6 6 1 September 2006 Short-Term Energy Outlook September 12, 2006 Release Overview August began with a surge in oil prices, but prices fell throughout most of the month and into early September, led by the earlier-than-expected seasonal decline in gasoline prices. The average retail price of regular motor gasoline fell from $3.04 per gallon on August 7, 2006, to $2.62 per gallon on September 11, 2006, and is expected to fall to an average of $2.55 per gallon in January 2007 before rising again into next summer. In 2006 and 2007, the WTI crude oil spot price is projected to average around $70 per barrel (West Texas Intermediate Crude Oil Price). Retail regular gasoline prices are projected to average about $2.65 per gallon in both 2006 and 2007 (Gasoline and

U.S. Reflects World Market
4 4 Notes: U.S. crude oil inventories reflect the world situation. U.S. inventories were drawn down in 1999 as world demand exceeded world supply of crude oil as OPEC cut back on production. Low crude oil inventories go hand in hand with low product inventories. Product inventories were also drawn down to help meet demand, as was seen with gasoline this Spring. The rise in crude oil inventories earlier this year, while indicating an improvement in the market balance, appears to be short-lived, just as we had predicted a few months ago. Looking at U.S. crude stock levels in April and May can be misleading, since increases then were more reflective of the surge in WTI and U.S. product prices in the 1st quarter. With U.S. crude oil stocks drawn down by more than 20 million barrels from
8, 2007 (next release 2:00 p.m. on March 15, 8, 2007 (next release 2:00 p.m. on March 15, 2007) Since Wednesday, February 28, natural gas spot prices generally increased east of the Rocky Mountains and decreased in the Rocky Mountains and to the west. On Wednesday, March 7, prices at the Henry Hub averaged $7.52 per MMBtu, gaining 28 cents per MMBtu, or about 4 percent, from the level of the previous Wednesday (February 28). The NYMEX futures contract for April delivery at the Henry Hub settled at $7.366 per MMBtu on Wednesday, March 7, rising about 7 cents per MMBtu, or nearly 1 percent, from the settlement price of $7.300 recorded last Wednesday, February 28. Natural gas in storage was 1,631 Bcf as of March 2, which is 14 percent above the 5-year average. The spot price for West Texas Intermediate (WTI) crude
7, 2002 (next release 2:00 p.m. on July 5) 7, 2002 (next release 2:00 p.m. on July 5) Since Wednesday, June 19, natural gas spot prices increased at most locations, despite declines ranging between 5 and 14 cents per MMBtu on Wednesday, June 26. For the week, prices at the Henry Hub increased 19 cents to $3.42 per MMBtu, which is an increase of almost 6 percent. High temperatures and rising crude oil prices contributed to increased cooling demand for gas, which spurred the price hikes. The NYMEX futures contract for July delivery at the Henry Hub expired yesterday (June 26) at $3.278 per MMBtu, falling over 17 cents in its final day of trading. Natural gas in storage increased to 2,184 Bcf, which exceeds the 5-year average by more 20 than percent. The spot price for West Texas Intermediate (WTI) crude
2 2 1 Short-Term Energy Outlook June 2002 Overview World Oil Markets: May marked the third consecutive month that the OPEC basket price averaged above $22 per barrel, the lower end of OPEC's target range for the OPEC basket price. The OPEC basket price has been above $22 per barrel since March 8, and is projected to remain within the target range throughout the forecast period, with prices rising at end-2002 and early 2003 before declining again in mid-2003. The price of West Texas Intermediate (WTI) was almost $1 per barrel higher in May than in April, averaging $27.04 per barrel (Figure 1). Summer Motor Gasoline Update: Retail average regular grade motor gasoline prices declined by just one cent in May. This follows a substantial 30-cent increase between February and April.

There will be no issue released on Monday, April 8. The next issue will be released on Thursday, April 11. Overview: Monday, April 1, 2002 Spot prices fell sharply after Tuesday, March 26, during last week's holiday-shortened trading, as unseasonably cold temperatures began to moderate around midweek in many high gas consumption areas. (See Temperature Map) (See Deviation Map) With the exception of the expiring near-month contract, futures contract prices also trended down, but the decreases were relatively modest. By Thursday's end of trading (both spot and futures markets were closed for Good Friday, March 29), the Henry Hub average spot price had declined by $0.35 per MMBtu since the previous Friday (March 22) to $3.19. The NYMEX futures contract for April delivery at the Henry Hub expired on Tuesday on an upswing, gaining almost 15 cents in 2 days to close out trading at $3.472 per MMBtu. The new near-month contract (May delivery) ended trading on Thursday at $3.283 per MMBtu, down just over 9 cents in 2 days as the near-month contract. The spot price for West Texas Intermediate (WTI) crude oil continued its steady rise, with modest gains early in the week punctuated by a 42-cent per barrel increase on Thursday. The WTI spot price at week's end was $26.21 per barrel ($4.52 per MMBtu), up $0.62 per barrel over the previous Friday. This is the highest price for WTI since the third week of September 2001.

Robe* Abstract We document that, starting in the Fall of 2008, the benchmark West Texas Intermediate (WTI) crude oil has periodically traded at unheard of discounts to the corresponding Brent benchmark. We further document that this discount is not reflected in spreads between Brent and other benchmarks that are directly comparable to WTI. Drawing on extant models linking inventory conditions to the futures term structure, we test empirically several conjectures about how time and quality spreads (prompt vs. first-deferred WTI; prompt Brent vs. WTI)

The rise and fall of cosmical physics: notes for a history, ca. 1850-1920
In the period from about 1890 to 1915 an interdisciplinary and unifying research programme known as "cosmical physics" attracted much scientific and public attention. It typically included aspects of the earth sciences (such as magnetic storms and atmospheric electricity) combined with astronomical subjects (such as the solar corona and cometary tails), but there was no unanimity as to the precise meaning of cosmical physics, which collapsed after World War I. The essay covers the history of cosmical physics as it unfolded in particular in Germany, Austria, England and Scandinavia. Among the scientists who contributed to the development of cosmical physics were Wilhelm Foerster from Germany, Wilhelm Trabert from Austria, Kristian Birkeland from Norway and Svante Arrhenius from Sweden. While cosmical physics did not usually involve a cosmological dimension, both Birkeland and Arrhenius constructed cosmologies based on their work on auroral and other phenomena.

Hydrodynamic causes and effects of air bubbles rising in very viscous media
Detailed understanding of two-phase gas liquid flows is imperative for developing efficient multi-phase reactors through precise control of mixing and reaction kinetics. The bubble column is a good apparatus for elementary studies of such flows. In the current study experiments are conducted to assess the effect of liquid viscosity on flow dynamics inside a bubble column. Corn oil and water are used as the continuous media, and air was the dispersed media. The objective of this effort is to use the results for a qualitative validation of the numerical simulations.

Predicted Versus Actual Savings for a Low-Rise Multifamily Retrofit in Boulder, Colorado
To determine the most cost-effective methods of improving buildings, accurate analysis and prediction of the energy use of existing buildings is essential. However, multiple studies confirm that analysis methods tend to over-predict energy use in poorly insulated, leaky homes and thus, the savings associated with improving those homes. In NREL's report titled 'Assessing and Improving the Accuracy of Energy Analysis of Residential Buildings,' researchers propose a method for improving the accuracy of residential energy analysis methods. A key step in this process involves the comparisons of predicted versus metered energy use and savings. In support of this research need, CARB evaluated the retrofit of a multifamily building in Boulder, CO. The updated property is a 37 unit, 2 story apartment complex built in 1950, which underwent renovations in early 2009 to bring it into compliance with Boulder, CO's SmartRegs ordinance. Goals of the study were to: 1) evaluate predicted versus actual savings due to the improvements, 2) identify areas where the modeling assumptions may need to be changed, and 3) determine common changes made by renters that would negatively impact energy savings. In this study, CARB seeks to improve the accuracy of modeling software while assessing retrofit measures to specifically determine which are most effective for large multifamily complexes in the cold climate region. Other issues that were investigated include the effects of improving building efficiency on tenant comfort, the impact on tenant turnover rates, and the potential market barriers for this type of community scale project.

Rise in gas-fired power generation tracks gains in turbine efficiency
Natural gas-fueled gas turbines--in both simple and combined-cycle configurations--will account for most power generation capacity additions through 2000. It is widely agreed that gas turbines will remain the dominant form of technology for power generation for the next decade or two, making them the power generation technology of choice for today and the future. The pre-eminent stature of gas turbines can be attributed to their low capital costs, high efficiency, low emissions, short permitting and construction lead times, and proven reliability. The versatility of gas turbines also makes them unique among power generation technologies, as they can economically serve a wide spectrum of applications and sizes--from distributed generation to industrial cogeneration and central station generation. Three primary factors contribute to the growing interest in gas turbine-based power generation and the role gas turbines will play in the future power generation market: An optimistic outlook for the supply and price of natural gas; technology advances that have produced substantial improvements in efficiency and emissions; and emissions regulations that may favor the use of gas turbines over traditional fossil-fueled steam turbines. These three factors are discussed.

We study an active-region dextral filament that was composed of two branches separated in height by about 13 Mm, as inferred from three-dimensional reconstruction by combining SDO and STEREO-B observations. This 'double-decker' configuration sustained for days before the upper branch erupted with a GOES-class M1.0 flare on 2010 August 7. Analyzing this evolution, we obtain the following main results. (1) During the hours before the eruption, filament threads within the lower branch were observed to intermittently brighten up, lift upward, and then merge with the upper branch. The merging process contributed magnetic flux and current to the upper branch, resulting in its quasi-static ascent. (2) This transfer might serve as the key mechanism for the upper branch to lose equilibrium by reaching the limiting flux that can be stably held down by the overlying field or by reaching the threshold of the torus instability. (3) The erupting branch first straightened from a reverse S shape that followed the polarity inversion line and then writhed into a forward S shape. This shows a transfer of left-handed helicity in a sequence of writhe-twist-writhe. The fact that the initial writhe is converted into the twist of the flux rope excludes the helical kink instability as the trigger process of the eruption, but supports the occurrence of the instability in the main phase, which is indeed indicated by the very strong writhing motion. (4) A hard X-ray sigmoid, likely of coronal origin, formed in the gap between the two original filament branches in the impulsive phase of the associated flare. This supports a model of transient sigmoids forming in the vertical flare current sheet. (5) Left-handed magnetic helicity is inferred for both branches of the dextral filament. (6) Two types of force-free magnetic configurations are compatible with the data, a double flux rope equilibrium and a single flux rope situated above a loop arcade.
