Many transportation projects require acquisition of land and accommodation of utility facilities in the right-of-way. The Federal Highway Administration, American Association of State Highway and Transportation Officials, and National Cooperative Highway Research Program sponsored a scanning study of Australia and Canada to learn about innovative practices for right-of-way and utility processes. The study complemented a 2000 study of European countries. The scan team identified nine priorities for U.S. implementation: promote incentive-based reimbursement for utility relocations, pursue corridor preservation strategies, use an alliance contract approach to integrate right-of-way acquisition and utility coordination, enhance cooperative relationships with property owners to facilitate timely property acquisition, develop geographic information system (GIS)-based right-of-way project and asset management systems, promote visualization techniques to communicate project impacts, promote use of multiple-level memorandum of understanding (MOU) structures, promote use of utility coordination best practices during construction, and develop a framework to establish proficiency of right-of-way and utility professionals.


The Board. These are the words artistic directors and general managers hear repeated most often during the time they are employed at a theatre. The words have many connotations. In my experience, and for most people involved in the operation of a theatre, the board is a relatively anonymous group of people who wield power and influence and with whom the administrative personnel must deal on a regular basis to receive official sanction for their actions. The board may also be perceived as a group of well-meaning individuals from the community who contribute to the organization in a practical and philosophical manner. And in rare instances, the board can be viewed as indispensable to the maintenance and operation of the theatre. Unfortunately, the majority of the time, the board is viewed by many staff members as a necessary obstacle to be overcome and, at times, as a hindrance to the operation as a whole.


Previous in vitro and in vivo studies have shown that the reductive metabolism of ronidazole ((1-methyl-5-nitroimidazole-2-yl)-methyl carbamate, I) results in the formation of a reactive intermediate which covalently binds to tissue proteins with concomitant loss of the C/sub 4/ proton. Although protein-binding accounts for only a small fraction of the metabolism of I, loss of the C/sub 4/ proton is quantitative with the metabolism of I. In order to investigate the identity of the reactive intermediate, the stoichiometry of nitro group reduction and 4-/sup 3/H release from (4-/sup 3/H)-labeled I by dithionite was determined under anaerobic conditions. Nitro group reduction was followed by the decrease in absorbance at 310 nm while labilization of the 4-/sup 3/H was quantitated as the volatile /sup 3/H recovered after lyophilization of the reaction mixture. Nitro group reduction and 4-/sup 3/H release were directly related and reached a maximum at 2.0 mole of dithionite per mole of I. Identical results were obtained over a 10-fold concentration range of I, ruling out possible bimolecular reactions between I and a partially reduced species. These data indicate that 4 electron equivalents are required for maximal 4-/sup 3/H release and nitro reduction of I. While these data are consistentmore » with reduction of I to a reactive hydroxylamine, the possibility of 4-/sup 3/H loss from a nitroso intermediate followed by rapid reduction to the hydroxylamine cannot presently be ruled out.« less


Relationships between healthy haulm area (HHA) and yield, and between losses of HHA and yield in the potato late blight system, were evaluated in several seasons and fields variously affected by the disease in Israel. The results showed that because of the different yield potential of potatoes cultivated in different conditions, evaluation of crop losses cannot be separated from evaluation of yield potentials of the crop as influenced by environmental and cultural factors.

In one calculation the yield and the HHA in the healthiest plot in each field were equated to 100% and losses in other plots were derived from comparisons with this plot. In such a calculation the relationships of yield loss to HHA loss in all fields and seasons fitted one regression equation, and a high correlation was obtained between both parameters. However, the actual haulm areas and yield weights differed widely from one field to another, even in the healthiest plots. Also, a similar percentage of destroyed haulms sometimes corresponded to different areas of the remaining haulms and to different yields. So no correlation was found between HHA and yields over all fields and seasons. Such a correlation was found only for several plots, variously affected by late blight, in the same field and season and in different fields and seasons yields responded in a different way to increases in HHA.


Two coal slurry line proposals show promise for quicker construction than other current proposals Energy Transportation Systems Inc. (ETSI) has proposed to move 25 million tons/yr coal from near Gillette, Wyo., to terminals at Pryor, Okla., and Newport and Redfield, Ark., with a spur to barge-loading facilities on the Mississippi River at Penton, Miss. ETSI has estimated that the 1355 mi, 38 in. system would cost $1.3 billion 1979 dollars and up to $1.7 billion by 1984. A group, led by Nevada Power Co., has proposed a 12 in., 70 mi line to link South Central Utah coal reserves with a powerplant near St. George, Utah; and a 22 in., 183 mi, 9.1 million ton/yr line to serve a generating station near Las Vegas, Nev. Four other coal slurry line proposals stalled due to right-of-way and water supply problems; feasibility studies by Boeing Co. on a 650 mi., 26 in. line from Utah to an export terminal at Oxnard, Calif.; and current congressional legislation providing power of eminent domain to slurry lines legislation are discussed.


PURPOSE
To assess the correlation between mean lethal radiation doses (Do) with NMR water proton spin lattice relaxation time (T1) in different phases of Hela cells.

METHODS
Analysis of T1 with Do was assessed in M, G1, G2 and S-phase at energies of 220 kVp, 280 kVp and 1.25 MeV (Co-60).

RESULTS
T1 against Do in M, G1, G2, and S phase at 220 kVp yield a correlation of 0.80. At 280 kVp and 1.25 MeV the correlation is 0.77 and 0.82 respectively.

CONCLUSION
It appears that T1 value decreases from M phase (1020 ± 84 ms) to S phase (534 ± 43 ms). The Do values increases from M phase to S phase. The variation in T1 and Do in different phases of the cell cycles provide a clue to time the mitotic phase at the radiation treatment time. It appears that T1 value decreases from M phase (1020 ± 84 ms) to S phase (534 ± 43 ms). The Do values increases from M phase to S phase. The variation in T1 and Do in different phases of the cell cycles provide a clue to time the mitotic phase at the radiation treatment time.


When problem behavior occurs infrequently during assessment, identification of its maintaining variables (via functional analysis) may by difficult or impossible. A strategy for altering standard functional analysis conditions was evaluated after initial assessment results yielded undifferentiated, low-rate responding. Several variables that may influence behavior were identified and systematically manipulated during modified functional analysis sessions: noncontingent attention and tangible items were delivered to peer confederates during sessions while the participant was ignored (combined establishing operations), consequences were delivered for longer durations (enhanced reinforcer characteristics), participants were given access to attention and preferred tangibles during the escape interval of demand conditions (combined contingencies), and all visible cues related to observation were removed from the alone condition (covert observation). An additional manipulation involved increased exposure to contingencies associated with each session by conducting longer sessions. Functional analysis conditions were conducted until differentiated rates of responding were observed in one or more of the modified conditions. Seven individuals participated in the study. Results for 3 participants showed that the modified conditions produced differentiation (i.e., higher rates of problem behavior in one or both of the social-reinforcement conditions). One participant began to engage in high rates of self-injurious behavior during the covert alone condition. Results for the 3 remaining participants showed that increased exposure to standard functional analysis conditions produced higher rates of responding than standard-length sessions. The overall results suggested that this may be a viable model for the assessment of low-rate behavior. ( en )

It is well known the relation –sometimes deceiving– that has been established by poets between literature and life. In the case of cursed poets, literature and life usually identify with each other, and talking about Alejandra Pizarnik, we could even establish this relation between literature and death, thus nothing is more daily than life. With this essay we try to identify the threads that converge and interweave the verses and the life, to be wandering and at the same time a prisoner, to have wings but stay in a cage, the confinement in a wandering reality. We will analyse the poetic individual and, at the same time, the construction of a character in life .


This paper introduces the testing of annular hyperboloid mirror with 460mm diameter in the Cassegrain system. To improve the testing efficiency and meet the requirements of utilization, the study is carried out from three stages: precision grinding, precision polishing, and optical coating. In the precision grinding stage, the annular Zernike polynomial is used to fit the measured surface combining with the data measured from the coordinate measuring machine, so that it can facilitate the testing of the distribution of the surface shape deviation over the entire surface. During the precision polishing stage, a feasible Offner compensator is designed to achieve the goal of high-precision testing of the hyperboloid surface, with a measurement accuracy of RMS≤0.02λ. Also, 0.5-0.7μm and 3-5μm dual-band high reflectivity and high uniformity reflective coating is designed for the Cassegrain system requirements, the actual test reflectivity is 96.2%, which can meet the design requirements.

Abstract. The effects of geometry and horizontal positioning of ultrathin triangular silicon nanowires (SiNWs) on the function of solar cells (SCs) have been investigated. Two differentiated methods have been presented to improve the current density of SiNW-SCs. First, a semiperiodic array is used for better utilization of the optical antenna effect. In the second method, several NWs with different geometries are used to achieve broadband absorption. The key to increase absorption is irregularity. Therefore, maximum light absorption is achieved by introducing irregular NWs. A set of optimized irregular NWs have better properties compared to other broadband structures. Using irregular NW arrays, the increase in the absorption of SCs can be improved without applying more absorbent materials. Optimization processes are used to obtain the maximum current density of SCs.

Revolutionary war fiction is an important category in contemporary Chinese literature. In the period between 1950 and 1960,war fiction put the emphasis on figure of the position hero, namely, the revolution romanticism and heroism. It was this emphasis that overwhelmed issues which relate to that suffering resulting from the war experience. In fact, the individual 'self was ignored completely in these early works. In the literature of the 1980s,the themes of war fiction changed from depicting heroes and heroism, to the portrayal of the ordinariness of heroes, and the common people in their heroic deeds. At the same time, the complexity and richness of the characters become a new focus of war fiction. In comparison with Russian war fiction, and based on writings of the 1990s,specifically Deng Yiguangs fictions, the paper demonstrates that war and sufferance have a close link to the representation of heroism. In shifting the focus from the description of heroic deeds and heroic adoration, to efforts which attempt to unravel the colorful and complex inner psychical world of the characters, contemporary war fiction reaches an objective comment on heroes and heroism. In doing this, the paper argues that contemporary Chinese war fiction has transcended the issue of humanity and humanism.


A 3D cone separator geometry for lithium-ion batteries has been optimized taking into account the increase of radius size of one side. Theoretical simulations have been carried out for evaluating the influence of radius size in the cone structure at different discharge rates (1 C and 60 C) in which it was also determined the produced ohmic heat. The value of the discharge capacity in the cone structure depends on the increases of the radius, which is correlated with the electrolyte volume and interface between free electrolyte/cathode. The optimum balance of these parameters is essential for obtaining higher battery performance through this geometry that can be used in the next generation of lithium-ion batteries.


This paper presents a novel input current shaper based on a quasi‐active power factor correction (PFC) scheme. In this method, high power factor and low harmonic content are achieved by providing an auxiliary PFC circuit with a driving voltage which is derived from a third winding of the transformer of a cascaded dc/dc flyback converter. It eliminates the use of active switch and control circuit for PFC. The auxiliary winding provides a controlled voltage‐boost function for bulk capacitor without inducing a dead angle in the line current. Since the dc/dc converter operates at high switching frequency, the driving voltage is also of high switching frequency, which results in reducing the size of the magnetic components. Operating principles, analysis and experimental results of the proposed method are presented. Copyright © 2011 John Wiley & Sons, Ltd.


The Basilica of Pilar located in the city of Zaragoza is one of the most well known spanish cathedral. Several domes of this church contain frescoes authored by Francisco de Goya. Some of the ~aintingi~have suffered in the past decades due to structural pathologies and a computer modelling was carried out aimed to find the links between the structural behaviour of the construction and the existing painting problems. The computational study is not finished yet and more information will be provided in the future. 1. Church description The Basilica of Pilar in Zaragoza is one of the most important worship places in Spain [l]. More than a thousand years ago a small chapel, was built in that location; the initial construction evolved eventually into a romanesque church, including an adjacent cloister. Later, a gothic extension enlarged the preexisting sanctuary. Nevertheless, all the aforementioned constructions were of small size compared with the huge extension which took place in XVII century when the project of a baroque church was set up by the spanish architect Ventura Rodriguez. The actual temple of rectangular shape, measures slightly more than 100 m in the longitudinal direction and about 70 m in the transversal one.


Cross walls and buttress walls are common construction methods used in Taiwan for protection of adjacent buildings during excavation. It is generally recognized, but not verified, that both methods have good effects in reducing wall movement and ground settlement. However, the design methodologies for cross walls and buttress walls in excavations are still highly empirical because of lack of case histories with good monitoring results. In this study, a case history, with a well documented construction sequence, of good construction quality, and with good monitoring results, is presented. According to the monitoring results, the wall movement and ground settlement, at the cross wall or near it, can be reduced significantly. The effect of buttress walls in reducing wall movement or ground settlement depends on the mobilized shear strength or frictional resistance, i.e., lateral movement of the retaining wall. If the excavation causes large wall movement, buttress walls should have a certain effect in reducing wall movement or ground settlement. However, buttress walls may have only a slight effect in reducing wall movement and ground settlement when the retaining wall shows only a small movement.

The fall armyworm is a highly polyphagous migratory lepidopteran pest species. It can colonize over 80 different plant species including many grasses, and crops such as alfalfa, soybean, sorghum, and corn. In Pennsylvania, low populations are usually present late in the summer, but population densities are rarely high enough to be of economic concern in field corn. On the rare occasion that fall armyworm is problematic in field corn; the late-season timing of the infestations makes them difficult to manage because insecticide application may require specialized equipment to pass over tall corn. Fall armyworm is more likely to be an economic pest in sweet corn and vegetable crops.


ABSTRACT:  This study examines how protest format and use of an agent affect the magnitude of the adjustments obtained in property tax appeals. The sample includes all single-family residential properties in Harris County, Texas for which a property tax protest was filed in 2010 or 2011 (n = 290,022). A protest can be settled in one of three formats: electronically (only when an agent is not used), an informal hearing, or a formal hearing. Because an owner's decision to use an agent is voluntary, I use a two-stage estimation process to help control for potential selection bias. The first-stage probit model is used to generate the predicted probability that an owner will use an agent, while the second-stage Tobit regression models the appeals adjustment as a function of protest format, agent use, control variables, and the selection-bias variable. Empirical results show that when an owner does not use an agent, appeals adjustments for electronic settlements are smaller than for informal settlements, and ap...

B EFORE DISCUSSING the individual factors responsible for evolution, it seems desirable to describe some of the patterns of variation which are the outcome of these processes. These exist on two different levels; first, that within the species and, second, that involving the different species of a genus or larger grouping. As is discussed in greater detail in Chapter VI. the distinction between these two levels is that of whether th~ pattern is essentially continuous or only partly discontinuous. owing to the more or less free interchange of genes between the various individuals or populations constituting the pattern, or whether the presence of isolating mechanisms preventing or greatly restricting mating and gene interchange has produced a number of sharply discontinuous and distinct populations or population systems.


As large scale biometric systems have been deployed throughout the landscape of the federal government, a new set of challenges and expectations have arisen. The ability to address increasing database sizes, demands on throughput, and privacy / legal issues are just a few examples of challenges at the forefront. Despite these challenges, the large scale systems are expected to continue to improve in terms of accuracy. In response to such challenges and expectations, systems relying on a single source of biometric input are transitioning to multi-biometric implementations. Traditional motivations behind the application of multi-biometric systems have centered on improving recognition performance, increasing population coverage, deterring spoof attacks, and reducing failure-to-enroll rates. The potential for improvement associated with these motivations is typically thought to come at the expense of increased processing time and computational complexity. In this paper, we provide supporting arguments for expanding the basis of multi-biometric system evaluation to reflect a holistic scope. Namely, the best multi-biometrics systems will maximize the degree in which requirements corresponding to the characteristics of universality, uniqueness, permanence, measurability, performance, acceptability, and circumvention are met. Additionally, we will demonstrate how evaluating the requirements of large scale federal multi-biometric systems necessitate an increased level of granularity beyond the traditional seven characteristics. Finally, we provide an example prioritization scheme which demonstrates how the overall measure of success need not uniformly consider all characteristics.


Aims. Coronary artery disease (CAD) is the first cause of death in developed countries and Iran. It is treated by three methods; drug, percutaneous coronary intervention (PCI) and coronary artery bypass surgery (CABS). In addition of physicians' decision in choosing the treatment method, patients opinion is very important and the advantages of the treatment method are questioned. This study was to compare the advantages of CABS and PCI treatment methods in quality of life after the treatment. Materials & Methods. In a descriptive-analytical study, 190 CAD patients treated with CABS or PCI were selected by purposed sampling method from the list of one of the Tehran city hospitals. Then, during a structured interview, Nottingham standardized quality of life questionnaire was completed. Data was analyzed by independent T-test and chi square by using SPSS 11 software. Results. In patients treated with CABS the average score of quality of life was 18.56± 3/255 and in the group treated with PCI it was 22.67±2/691. Independent T-test showed a significant difference between these two methods (p<0.05). The quality of life in patients treated with CABS was beeter than the group treated with PCI. Conclusion. Although treatment with CABS is more difficult and more expensive than PCI, but it provides a better quality of life.


Manipulation of sowing dates is an obviously good strategy to minimize the bacterial blight disease caused by Xanthomonas axonopodis pv. Malvacearum (Smith) dye with relation to environmental factors. The bacterial blight appeared to a level of 5.37 per cent incidence with 2.35 per cent intensity in 31st (MW) in 27th June sown crop while (July) 7th and 17th 2007) sown plot disease appeared in 32nd (MW) The level of incidence was 6.67 and 1.66 per cent and intensity 2.33 and 0.41 per cent respectively. The bacterial blight disease increased progressively and reached its peak i.e. 53.67 per cent incidence with 22.35 per cent intensity in 42nd (MW) in lst sown plot. Incidence and intensity reached its maximum in 42nd (MW) Bacterial blight incidence and intensity was maximum in 1st sown plot than 2nd and 3rd sown plot and disease appears a week before than late sown lot. Maximum temperature and blight sunshine hours (BSH) was found positive and significantly associated with in crease in disease.


Field investigation and sporadic drilling indicate greater kaolin clay reserves at Mesa-Alta than previously suspected. In fact, high-grade kaolin clay has been found at several different localities in the Mesa Alta area but topography, poor outcrops, and heavy forest cover prevent accurate determination of reserves. Geology of the area is suggestive of innumerable pockets and lenses of high-quality kaolin clay. It is conjectural if such occurrences can be discovered and economically mined in commercial quantity and quality.

Abstract George Eliot's novel, Felix Holt, the Radical, is criticized for its legal complexities. Such criticism is misplaced when Felix Holt is read as a law novel in dual senses. First, Eliot employs law and legal events to motivate the various characters along the novel's various plots. In that sense, Felix Holt is an instance of law in literature. Second, Eliot employs the human characters to embody aspects of law's nature. This enables Eliot to use those characters to examine the nature of law or law's character. Thus, Felix Holt can be read as a work of jurisprudence and, therefore, as a rudimentary instance of jurisprudence (or law) as literature.


The VAX/VMS process schedule is briefly described. A simple priority-driven round-robin queuing model is then constructed to analyze the behavior of the time-critical processes of VAX/VMS under such a schedule.
 Mean and variance of the conditional response time of a process at a given priority are derived, conditioned on the amount of service time required by that process. Numerical results are given with comparisons to the ordinary priority queuing systems.


Protein kinases have long been regarded as essential to signal transduction processes that relay extracellular cues to effect changes in cell behavior. There has been a growing appreciation in recent years that phosphorylation-dependent signaling pathways in eukaryotes are organized into larger networks through extensive crosstalk and feedback mechanisms. Glycogen synthase kinase-3b (GSK3b) is a serine-threonine kinase that has integral roles in mediating signal integration and crosstalk in mammalian cells [1]. As its name suggests, GSK3b was initially identified as a regulator of metabolism through phosphorylation of glycogen synthase. In the 40 years since its discovery, GSK3b has been found to participate in numerous signaling pathways, most prominently the Wnt pathway important for cell fate specification during development. To date more than 100 GSK3b substrates have been identified [2]. Accordingly, the kinase has emerged as a key regulator of many fundamental cellular processes, including differentiation, proliferation, metabolism, and motility. The capacity for GSK3b to facilitate crosstalk between signaling pathways is related to its unusual mechanism of substrate targeting. GSK3b recognizes substrates that have been 'primed' by prior phosphorylation at a position four residues C-terminal to its own site of phosphorylation [3]. Primed substrates interact with GSK3b through a specific phosphate binding site composed of three conserved basic residues located in its catalytic cleft [4,5]. GSK3b substrates are typically primed by other kinases, effectively putting the substrates under control of two pathways [1]. In some cases, substrates harbor runs of multiple serines positioned four residues apart, leading to multisite phosphorylation by GSK3b through 'self-priming'. For example, glycogen synthase is initially phosphorylated by casein kinase 2 (CK2), which primes it for subsequent phosphorylation by GSK3b at no less than four additional serine residues. Given its widespread roles in controlling cell function, it is perhaps not surprising that the kinase activity of GSK3b is tightly regulated through multiple mechanisms. One key mode of regulation involves direct phosphorylation of Ser9, a residue within its flexible N-terminal region. Ser9 phosphorylation is induced by insulin and peptide growth factors, and is primarily attributed to the phosphoinositide-dependent kinase AKT (also called PKB) [6]. Phosphorylation at Ser9 converts the N-terminal region of GSK3b into a pseudosubstrate that interacts intramolecularly with the catalytic cleft, engaging the same phosphate binding site utilized for recognition of primed substrates [5]. This interaction inhibits the kinase by blocking access of substrates to the active site. An article by Fu and coworkers in this issue of FEBS Letters describes an intriguing twist on the GSK3b pseudosubstrate inhibition mechanism [7]. The authors noted that two additional phosphorylatable residues (Thr7 and Thr8) are located immediately upstream of Ser9 in the GSK3b N-terminal region. Furthermore, these residues are conserved across the animal kingdom, suggesting that they are likely to be functionally important. Mutation of either of the two residues to alanine dramatically reduced both basal and growth factor-induced phosphorylation at Ser9, yet appeared to have no effect on the ability of AKT to phosphorylate the site in vitro. Focusing on Thr7, the authors found convincing evidence that it is phosphorylated in cells by intestinal cell kinase (ICK). ICK is a relatively understudied serine-threonine kinase. Loss-of-function germline mutations in ICK cause endocrine-cerebro-osteodysplasia in humans, a syndrome characterized by defects in skeletal and lung development [8]. Negative regulation of primary cilia formation and consequent signaling through the hedgehog morphogen sensing pathway have been proposed to underlie the developmental role of ICK [9,10]. In addition, ICK positively regulates cell proliferation and suppresses autophagy, likely due to activation of mTOR complex 1 (mTORC1) through phosphorylation of its core component raptor [11]. As anticipated, modulation of ICK expression in cells affected both Thr7 and Ser9 phosphorylation of GSK3b. Unexpectedly, phosphorylation at Thr7 by

Cynomolgus monkeys were tested in two computer‐controlled visual associative memory tasks. The monkeys chose between visual objects on a screen by touching one. In the configural learning task one correct object and one wrong object were presented in each trial. Each of these two objects was composed of two coloured alphanumeric characters abutted together. The designation of the objects as 'correct' or 'wrong' followed a configural rule: e.g. if AB and CD are correct objects then AD and CB are wrong. In the paired association learning task in each trial three spatially separate objects (single alphanumeric characters) were presented. The central object was an instruction cue and the designation of the side objects as 'correct' or 'wrong' choices followed a paired association rule: e.g. if A, C and B are presented (C in the centre) then A is correct and B is wrong: however, if A, D and C are presented then C is correct and A is wrong. Disrupting the direct cortico‐cortical interaction between the inferior temporal cortex and the prefrontal cortex by uncinate fascicle transection led to a learning deficit in the paired association task but not in the configural task. These results suggest that the uncinate fascicle facilitates visual‐visual associative learning only in the specific case where a visual object acts as an instruction cue to guide the conditional choice of another, spatially separate object, and they support the evidence for a specific role of the uncinate fascicle in the learning of conditional tasks with visual instruction cues.


This paper describes as workflow for combining high-resolution optical aerial imagery and airborne lidar measurements to identify supraglacial water features and estimate their depth. It then shows examples of the obtained results over three different water features with different characteristics and discusses the capabilities and limitations of the method in each of these environments. In particular, the authors argue that airborne data can provide a high-resolution data at large spatial scales that fill a gap between spaceborne and field-based measurements. measurements


FIELD EXPERIENCE WITH A PARTICULAR PORTLAND CEMENT SHOWED THAT THE CONCRETE MADE WITH THIS CEMENT DEVELOPED CRUSTING ON ITS SURFACE WHEN USED WITH A SET RETARDING ADMIXTURE. FALSE SET AND EXTRACTION TESTS WITH THIS CEMENT INDICATED THAT IT CONTAINED CALCIUM SULFATE HEMIHYDRATE AND WAS POTENTIALLY A FALSE-SETTING CEMENT. THE ADDITION OF THE ADMIXTURE DELAYED THE TIME AT WHICH THE FALSE SET DEVELOPED. RESULTS OF TESTS MADE WITH SILICA FLOUR-HEMIHYDRATE, WATER PASTES AND CLINKER-CALCIUM CHLORIDE WATER SLURRIES PROVIDE EVIDENCE THAT THE ADMIXTURE RETARDS BOTH THE RATE OF CALCIUM SULFOALUMINATE FORMATION IN A CEMENT PASTE AND THE RATE AT WHICH GYPSUM CRYSTALLIZES FROM PASTES THAT ARE SUPERSATURATED WITH RESPECT TO GYPSUM. /AUTHOR/


We continue our recent endeavor in which a time-dependent black hole solution of a one-loop quantum-corrected Einstein-scalar system was obtained and its near-horizon behavior was analyzed. The energy analysis led to a trans-Planckian scaling behavior near the event horizon. In the present work, the analysis is extended to a rotating black hole solution of an Einstein–Maxwell-scalar system with a Higgs potential. Although the analysis becomes much more complex compared to that of the previous, we observe the same basic features, including the quantum-gravitational trans-Planckian energy near the horizon.


On May 25 - 26, 2010, Universite Laval, the University of Windsor Faculty of Law and the University of Louisville Brandeis School of Law, hosted the Sixth Administrative Law Discussion Forum. These discussion fora, which have become an international academic success, have been held in a variety of venues in North America and Europe since the early 1990s. They are an initiative of Russell Weaver, Professor of Law & Distinguished University Scholar at the University of Louisville. The fora provide an opportunity for thoughtful exchange among administrative law academics on contemporary issues that cut across national borders.

The rampant use of chemical fertilizers contributes to the deterioration of the environment through depletion of fossil fuels, generation of carbon dioxide and contamination of water resources. It also leads to loss of soil fertility due to imbalanced use of plant nutrients that adversely impacts agricultural productivity. Now there is a growing realization that the adoption of ecological and sustainable farming practices can only reverse the declining trend in the global productivity and environment protection. Municipal solid waste management is gaining importance all over the developed and developing nations.

Background Schoolchildren are good agents of change and need to be educated and sensitized to specific issues of hunger and malnutrition through a question-and-answer process. Feeding Minds and Fighting Hunger (FMFH), a global project initiated by the Food and Agriculture Organization and partner organizations, attempts to help schoolchildren learn about these issues by introducing concepts in the prevention of hunger and malnutrition to teachers, and by facilitating transfer of knowledge to the children through a set of model lessons. Objective To test the feasibility of the FMFH approach to improve the nutrition knowledge of rural schoolchildren in three rural schools in Medak District of the South Indian state of Andhra Pradesh. Methods Participatory workshops for teachers were conducted to facilitate knowledge transfer to the children through interactive classroom teaching and other activities. The change in knowledge and thinking of children in the seventh and eighth grades was assessed by a questionnaire administered before and after the intervention. The questionnaire also assessed, in part, the status of local food security based on the sources of different food items in the households. Results The responses to the questionnaire suggested that the children's knowledge of nutrients and their functions was not good initially but improved after the intervention. However, their understanding of the social factors responsible for hunger and malnutrition was fairly good prior to the intervention. Improvement in responses to the question of what should be done to combat malnutrition also occurred after intervention. The community had village-level food security for rice and maize but depended partially or fully on outside sources for pulses, fruits and vegetables, and animal products. Conclusions The FMFH approach can be applied in rural schools where "the poorest of the poor" children can improve their understanding of balanced diets, better nutrition, the causes of malnutrition, and approaches to combat malnutrition.


The heat capacity and magnetization of a spherical crystalline powder sample of MnBr2·4H2O has been determined as a function of temperature in applied magnetic fields up to 30 000 G. The H−T diagram for the magnetic transformations has been obtained from the loci of the points inflection in the derived values of the rate of change of the entropy and magnetization with temperature at constant applied magnetic field. The loci of these points of inflection exhibit an abrupt change in slope, indicative of a transition occuring in the portion of the sample having the spin axis aligned parallel with the applied field. The observed phenomena are in agreement with the data reported for optical and microwave absorption.

Genomic variants of telomere-subtelomere junctions in Silene
latifolia chromosomes were cloned and sequenced. In addition to
the previously isolated subtelomeric sequence X43.1 (Buzek et
al., 1997), several novel telomere-associated sequences have
been characterised, including high-copy tandem repeat 15Ssp and
low-copy sequence BstB19. Their subtelomeric location has been
confirmed by pulsed-field gel electrophoresis and fluorescent
in situ hybridisation. Analysis of chromatin structures
(nucleosome phasing, nucleosome positioning) at these sequences
revealed their specific features

Camouflaged object detection (COD) involves segmenting objects that share similar patterns, such as color and texture, with their surroundings. Current methods typically employ multiple well-designed modules or rely on edge cues to learn object feature representations for COD. However, these methods still struggle to capture the discriminative semantics between camouflaged objects (foreground) and background, possibly generating blurry prediction maps. To address these limitations, we propose a novel mask-and-edge co-guided separable network (MECS-Net) for COD that leverages both edge and mask cues to learn more discriminative representations and improve detection performance. Specifically, we design a mask-and-edge co-guided separable attention (MECSA) module, which consists of three flows for separately capturing edge, foreground, and background semantics. In addition, we propose a multi-scale enhancement fusion (MEF) module to aggregate multi-scale features of objects. The predictions are decoded in a top-down manner. Extensive experiments and visualizations demonstrate that our CNN-based and Transformer-based MECS-Net outperform 13 state-of-the-art methods on four popular COD datasets.


One of the principal design objectives for a "quiet" hypersonic tunnel, where low disturbance levels are required, is to maintain laminar boundary layers on the nozzle wall at sufficiently high Reynolds numbers to obtain transition on test models. Tests were conducted in a small conventional Mach 5 nozzle to investigate the effects of several factors on transition in the nozzle wall boundary layer. The profiles of mean pitot pressure were measured and compared with theoretical predictions. The freestream disturbance levels and spectra were also measured using a constant current hot-wire anemometer and a fluctuating pitot pressure probe. The results of these measurements were used to determine whether the boundary-layer on the nozzle wall was laminar, transitional, or turbulent. For the present tests, roughness in the vicinity of the nozzle throat was the dominant factor controlling transition.

Background: Anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis is a term used to describe systemic vasculitides that affect small and medium-sized blood vessels. The three types of ANCA-associated vasculitis (AAV) are Granulomatosis with Polyangiitis (GPA), formerly Wegener's granulomatosis , Microscopic Polyangiitis (MPA), and Eosinophilic Granulomatosis with Polyangiitis (EGPA), formerly Churg-Strauss, with clinical presentation most frequently involving the respiratory tract, the kidney, the skin and the joints. ANCA-associated vasculitis is rare in children, with estimated prevalence of 3-4 per million, and even more rare is the manifestation of cardiac abnormalities secondary to ANCA-associated vasculitis in the pediatric population. Case Presentation: We present the cases of two teenage males who presented with cardiac valvular lesions secondary to Granulomatosis with Polyangiitis in addition to sinus, pulmonary, renal, and cutaneous involvement. These findings of cardiac valvular abnormalities in GPA have rarely been described in the literature in pediatrics. Both patients were treated with rituximab, high-dose methylprednisolone, and plasma exchange (PLEX) and showed improvement in their disease manifestations. Conclusions: A review of the literature revealed only five pediatric cases of ANCA-associated vasculitis with cardiac manifestations, and interestingly, three of the five had valvular involvement. Subsequent valvular involvement makes obtaining the diagnosis of ANCA-Associated Vasculitis very difficult due to concern for underlying infectious endocarditis and can lead to misdiagnosis given the rarity of cardiac involvement in ANCA-associated vasculitis. Routine echocardiogram is not always completed in newly diagnosed GPA, yet cardiac involvement can lead to severe consequences as was seen with our first patient in the form of thromboembolic stroke. We discuss the importance of keeping AAV on the differential when cardiac lesions are present as well as the importance of regular cardiac screening in newly diagnosed patients with AAV, as it is a major factor of cardiac morbidity and mortality in the adult population and can contribute substantially to management decisions.


In the past, thermosensitive gold nanoparticles have been synthesize successfully by O2 plasma modification and UV-induced grafting polymerization of poly(N-isopropylacrylamide) (PNIPAAm) after self-assembled monolayers (SAMs) by 11-Mercaptoundecanoic acid (MUA) including thiol group. But there were difficulties in quantitative analysis of modified nanoparticles. Quartz crystal microbalances (QCM) are transducers for chemical and biochemical sensing in general. The oscillation frequency of QCM will be affected when the adsorbed mass on the surface, in view of this characteristics, it can be used as mass sensor applications. On the gold film electrode of a QCM was modified by plasma-treatment and then UV-induced graft polymerization with functional monomers after SAMs has been carried out. MUA including thiol group was employed for the deposition of SAMs from ethanol solutions onto gold surfaces. O2 plasma treatments can be employed to generate sufficient amounts of peroxides and hydroperoxides on the SAMs for the subsequent UV-induced graft polymerization. The monomers used for graft polymerization were water-soluble NIPAAm. Contact angle and oscillation frequency of QCM measurements indicate that the SAM-modified Au surfaces could be an effective method making hydrophilic surface and reducing the frequency of QCM through the plasma modification and graft copolymerization with an appropriate monomer.


This study aims to determine the characteristics of DSSC using rosella flower extracts with variations in the distance of the light source to DSSC. The characteristics measured are current and voltage values and cell efficiency. A 150-watt halogen lamp is used as the light source. Light source was placed at a distance of 10 cm, 20 cm, and 30 cm. The voltage and current value of the halogen lamp with a distance of 10 cm to DSSC are greater than the distance of 20 cm and 30 cm. The test results show that the cell efficiency of 10 cm to DSSC is the most maximum with current (Imax) of 0.08 mA, maximum voltage (Vmax) of 306.7 mV and the efficiency of 0.046%. The smaller the distance of the halogen lamp to DSSC increases the intensity of the light so that the greater the DSSC output value. DOI:  http://dx.doi.org/10.17977/um024v5i12020p031


We report two cases of squamous cell carcinoma (SCC) of the breast. Case 1: A 46-year-old woman had a lump measured 1.0×1.0 cm in the right breast. Excisional biopsy was performed. Most of tumor cells consisted of SCC cells and in part ductal carcinoma cells were mixed, and therefore it was finally diagnosed as primary SCC of the breast. Case 2: A 48-year-old woman had a 1.9×1.5 cm lump in the right breast. Aspiration biopsy cytology revealed Class 5 (SCC). The tumor was excised. Histological examinations revealed pure type of SCC. She had a history of tongue carcinoma and lymph node metastasis, so this was diagnosed as metastatic SCC of the breast. It is easy to diagnose the breast tumor comprising of SCC mixed with ductal carcinoma components as prinary breast cancer. But pure type of SCC often presents difficulty indetermination whether it is primary or metastatic. It must be stressed on that there are two types of SCC, primary or metastatic, when pure type of SCC are obscured.


Aims. The relation connecting the emitted isotropic energy and the rest-frame peak energy of theFspectra of Gamma-Ray Bursts (the Amati relation), strictly depends on the cosmological model, so we need a method to obtain an independent calibration of it. Methods. Using the Union Supernovae Ia catalog, we obtain a cosmographic luminosity distance in the y-redshift and demonstrate that this parametrization approximates very well the fiducial st andard comsomlogical modelCDM. Furthermore, by this cosmographic luminosity distance dl, it is possible to achieve the Amati relation independent on the cosmological model Results. The cosmographic Amati relation that we obtain agrees, in the errors, with other cosmological-independent calibrations proposed in the literature. Conclusions. This could be considered a good indication in view to obtain standard candles by Gamma-Ray Bursts


The Dutch-Indonesian program in Indonesian Studies was inaugurated in January, 1975 as a four-year, bilateral exchange of research materials and personnel in het humanities and social sciences. The principal aim of the Program, one which links its diverse aspects and activities, is to stimulate the use by Dutch and Indonesian scholars of the enormous body of information about Indonesia written in Dutch to ensure, in other words, that the traditions of scholarship on Indonesia which many Dutch and Indonesian scholars have worked to establish during the colonial period would continue to be developed as a new generation of Dutch and Indonesian researchers take up the study of Indonesian societies and cultures.


SUMMARY How Can Life Design Counselling Enhance the Self-efficacy of a Learner from an Environment Challenged by Disadvantage? Abstract In this study the researcher intends to explore the influence of life design counselling on the self-efficacy of a learner from an environment challenged by disadvantage. Learners and youth from environments challenged by disadvantage have the tendency to feel disempowered by the situation in which they find themselves. Such situations are often characterised by unemployment, thus leaving them in uncertainty about the future and threatens their identity. According to Bandura (1977) people's achievement is determined by the interaction between their behaviour, personal factors and the environment. An investigation into the influence of life design counselling on the contextual experiences of the participant will be informed by career construction theory (Savickas, 2005) and self-construction theory (Guichard, 2005) which are both based on the constructivist paradigm. Increasing the participant's resources is pivotal given that career paths are influenced by individual and contextual factors, this study will employ a mixed methods research approach (qualitative approaches will be prioritised QUAL+quan) with a case study design. In order to improve the effectiveness of such an assessment the following data collection techniques will be used: Quantitative – Maree Career Matrix, Myers-Briggs Type Indicator, and Career Adapt –Ability Scale; Qualitative – Career Interest Profile, Structured questionnaires and interview, life line, collage, observations, and researcher's journal. The data collected will be analysed and interpreted by means of thematic content analysis. The researcher hopes to make recommendations that are meaningful for the selfand career construction of the participant, life design counselling practice, research and policy development that will be appropriate for contexts challenged by disadvantages.

Abstract : Description is given of the design and construction of a rocket borne instrument for the measurement of day airglow emissions. Design criteria included greater sensitivity, background discrimination, in-flight spectral calibration and increased spectral information. A scanning photometer was designed utilizing matched interference filter pairs mounted in a rotating turret and displaced approximately 5 degrees to one another. Two matched parallel light beams produced by a beam splitter are passed through the matched interference filter pair. The resulting scans are displaced in the spectrum by 10A and provide output signals from closely adjacent spectral regions. Measuring the difference in the two signals provides emission line information and discriminates against background. The sum of the signals provides the background information. Polarizing effects corrected by use of polaroid filters at the input aperture resulted in an overall reduction in sensitivity of the instrument. (Author)


Great increase in wireless access rates might be attainable using the large amount of spectrum available in the millimeter wave (mmWave) band. However, higher propagation losses inherent in these frequencies must be addressed, especially at ranges beyond 100 m and in non-line-of-sight (NLOS) settings. In contrast to the interference limited legacy cellular systems, where using more bandwidth is favorable, to use wider bandwidth for mmWave channels in noise limited settings may be ineffective or even counterproductive when accounting for channel estimation penalty. In this paper, we quantify the maximum beneficial bandwidth for mmWave transmission in some typical deployment scenarios where pilot-based channel estimation penalty is considered assuming a minimum mean square error channel estimator at the receiver. We find that, under I.I.D. block fading model with coherence time <inline-formula> <tex-math notation="LaTeX">$T_{c}$ </tex-math></inline-formula> and coherence bandwidth <inline-formula> <tex-math notation="LaTeX">$B_{c}$ </tex-math></inline-formula>, for transmitters and receivers equipped with a single antenna, the optimal (rate maximizing) signal-to-noise-ratio is a constant that only depends on the product <inline-formula> <tex-math notation="LaTeX">$B_{c}T_{c}$ </tex-math></inline-formula>, which measures the channel coherence and equals the average number of orthogonal symbols per each independent channel coefficient. That is, for fixed channel coherence <inline-formula> <tex-math notation="LaTeX">$B_{c}T_{c}$ </tex-math></inline-formula>, the optimal bandwidth scales linearly with the received signal power. Under 3GPP urban micro NLOS path loss model with coherence time <inline-formula> <tex-math notation="LaTeX">$T_{c}=5$ </tex-math></inline-formula> ms and coherence bandwidth <inline-formula> <tex-math notation="LaTeX">$B_{c}=10$ </tex-math></inline-formula> MHz, using 52-dBm equivalent isotropic radiated power (EIRP) at the transmitter and 11-dBi antenna gain at the receiver, the maximum beneficial bandwidth at 28 (resp. 39) GHz is less than 1 GHz at a distance beyond 210 (resp. 170) m with maximum throughput about 200 Mbps, and less than 100 MHz beyond 400 (resp. 310) m with maximum throughput about 20 Mbps. At EIRP of 85 dBm, corresponding to the FCC limit of 75 dBm per 100 MHz, 1 Gbps rate can be delivered using 1-GHz bandwidth up to 860 (resp. 680) m.


A remote experiment was developed and carried out to create a phenol/water phase diagram using a low-cost automated data collection system and an online video broadcast. Both the data and video from the experiment were transmitted in real-time. The remote lab experiment was evaluated using qualitative and quantitative questionnaires filled out by the students. The phenol/water phase diagram obtained is entirely consistent, with precision and accuracy compatible with what is expected to be achieved in conventional lab classes. The activity evaluation showed excellent acceptance by the students by doing this lab activity remotely.


This essay examines Charlotte Brontë's engagement with the textile industry from her earliest writings to her 1849 Condition of England novel Shirley in order to emphasize the role that Yorkshire and its staple industry played in her writing. Critics have discussed her interest in textile production largely in relation to Shirley. However, her fascination with cloth manufacturing is evident in many of her Angrian tales and some of her unfinished novels. This essay argues that through her early representations of mills and mill owners she formulated an understanding of political conflict and masculine power which helped to shape her mature writing. This culminates in Shirley with her critique of the taboo against educated women entering careers in trade and manufacturing.


Fetal growth is restricted by several reasons, e.g. reduced active transfer of placental villi and maternal circulation in the placental intervillous space fibrin deposit [1]. The placental infarction in preeclampsia also reduced oxygen transfer developing fetal hypoxia. Fetal blood PaO2 is 50 mm Hg or less [2], i.e., the fetus is rather hypoxic if compared to 100 mm Hg PaO2 of adult. Thus, the fetus tends to be hypoxic, which can damage fetal brain if hypoxia is severe and persisted. As there was fetal death in severe fetal asphyxia, hypoxic fetus was diagnosed in fetal monitoring and cured by early caesarean delivery after the diagnosis of fetal asphyxia, however, cerebral palsy did not reduce in the Dublin RCT of fetal monitoring, which was dissapointed and the reduction of cerebral palsy has been the important problem in fetal monitoring.


This paper studies,a new method for measuring flow rate characteristics of pneumatic solenoid valves,namely measuring sonic conductance C and critical pressure ratio b of pneumatic solenoid valves using discharge pressure curve of isothermal chambers.First,the principle and method of measurement are introduced.Second,four kinds of isothermal chambers are experimentally studied,and the experimental results indicate that the more copper threads stuffed,the better isothermal characteristics and the larger flow resistance.Finally,the isothermal chambers are used to measure the flow rate characteristics of same solenoid valves,and the measurement results indicate that the isothermal chambers can successfully test the flow rate characteristics,but they do not indicate that the better isothermal characteristics the smaller errors.By analysis,we know that isothermal characteristics and flow resistance diversely affect the errors,which isothermal characteristics lead to positive errors while flow resistance leads to negative errors.Measuring flow rate characteristics with isothermal chambers saves time and consumes less energy than ISO 6358 procedure,and the study promotes the practicalitycourse of isothermal chambers.


Forty-one specimens of the pontoniine shrimp genus Periclimenaeus Borradaile, 1915, from the Hawaiian region, collected between 1923 and 1937 and reported on by Charles H.

Research on China's urban planning sector has largely focused on its role in delivering economic growth and state objectives. Yet China's urban planning practices are producing new forms of social injustice, which few studies explicitly examine. The paper details three types of social injustice stemming from urban planning and urbanization processes: 1) economic disparities related to land and housing dispossession and speculation, 2) dissolution of social networks and relative precarity for rural-to-urban resettlement migrants, and 3) in-situ marginalization for residents excluded from urban planning. It further proposes that these types of social injustice can be addressed through distributional, participatory, and recognition-oriented mechanisms. Centering justice can reconfigure the aims, processes, and outcomes of planning practice, thereby reducing inequalities embedded within China's urbanization. Without deprioritizing economic growth and state-led entrepreneurialism, however, justice-oriented planning can offer but partial remedies. The conclusion discusses pathways for researchers and planners to contribute to a just planning transition and advance social justice in China's cities.

A method for producing the charged claylinked gel, and the use of the gel in absorbent articles is also described.


When it comes to trade law, it is true that there appear to be certain signs that we are moving back to non-discrimination and away from deeper forms of integration. However, this is possibly (and hopefully) only a limited and temporary shift. The strongest evidence of such a shift regards the apparent interpretation by the WTO Appellate Body (AB) of the key provisions in the TBT Agreement in such a way as to give prevalence to the national treatment standard in Article 2.1 over the necessity requirements in Article 2.2. For example, in US – Tuna II (Mexico) the AB found the U.S. dolphin-safe regulations under review inconsistent with Article 2.1, while also reversing the panel finding that the U.S. dolphin-safe regulations were inconsistent with Article 2.2. Such a result is surprising if one considers the general agreement among commentators that the disciplines embodied in the TBT Agreement (as well as in the SPS Agreement) went beyond the non-discrimination obligation of the GATT.


Learning features invariant to arbitrary transformations in the data is a requirement for any recognition system, biological or artificial. Such transformations may be learned using label information or from temporal data in an unsupervised manner by exploiting continuity. This paper presents a dynamical system for learning invariances from real-world spatial patterns in an unsupervised manner and in the absence of temporal continuity. The model consists of a simple and a complex layers. Given an input, the simple layer imagines all of its variations, each with a degree of consistency, and eventually settles for the most consistent reconstruction. During this imagination, the complex layer learns the consistent variations of the same pattern as a transformation in each spatial region. Experimental results are comparable to those from supervised learning. The conditions for stability of the system are analyzed.


The structure and the depth distribution of radiation damage caused in (111) Si by high-dose krypton implantations (E; = 150 keV, T; = RT, D1 = 5 x 1015 , D2 = 1 x 1016 and D3 = 5 x 1016 cm z ) have been investigated using techniques of transmission electron microscopy. Formation of secondary defects (Kr bubbles and microtwins) on subsequent different annealing procedures, i.e. during solid phase epitaxial regrowth of damaged layers by conventional furnace heating and liquid phase epitaxial regrowth by applying laser pulses is compared and discussed.

The efficient separation of butadiene (1,3‐C4H6) from C4 hydrocarbons is a critical step in petrochemical processes. However, the traditional cryogenic distillation suffers from energy‐intensity and serious environmental stress, necessitating the development of alternative technologies for efficient 1,3‐C4H6 separation. Herein, a 1,3‐C4H6 recognition mixed matrix membrane is reported via incorporating metal copper encapsulated a metal‐organic framework (CuBTC@Cu) into elastic poly(dimethylsiloxane) (PDMS). The resulting CuBTC@Cu/PDMS membrane can efficient separate 1,3‐C4H6 from various C4 hydrocarbons including 1,3‐C4H6/n‐C4H8, 1,3‐C4H6/iso‐C4H8, 1,3‐C4H6/n‐C4H10 and 1,3‐C4H6/iso‐C4H10, yielding superior selectivity of 5.11, 6.35, 4.78, and 10.30, respectively, with 1,3‐C4H6 permeability of 53240 Barrer. Notably, the appropriate π‐complexation interaction between butadiene molecules and CuBTC@Cu as well as suitable transmission channel size enable the membrane only permeable to 1,3‐C4H6 and block the permeation of other C4 hydrocarbons, showing a unique 1,3‐C4H6 recognition behavior in membrane separation. The concept of affinity‐relying separation combining molecular sieving would open a new direction for designing gas membranes for efficient light hydrocarbon separations.

In an attempt to increase the intermolecular attraction between polyorganosiloxane chains and rings, polar groups have been introduced into methyl groups attached to the silicon atoms. To avoid the usual weakening of the CSi bond by negative polar substituents, positive substituents of the type (CH3)3M (where M is Si, Ge, or Sn) were employed in this study. Cyclic trimers and extended linear polymers were prepared, both from the pure polar-substituted monomers and from mixtures of these monomers with octamethyltetrasiloxane. Intermolecular attraction was estimated by measuring viscositities and activation energies of viscous flow. The preparations also were compared in these respects with pure dimethylsiloxanes and with neopentylsiloxanes. The results show that intermolecular attraction is increased by the positive polar substitutents, and that the CSi bond is rendered more stable toward OH− attack by such positive substituents than by negative. More detailed analysis indicates that the effects of the groups on the viscosity of the polymers depends on: (1) the dipole attraction of the polar groups, (2) the bulk or steric effect of the enlarged group, and (3) the effect of the metal M upon the ease of rotation of the methyl groups (the characteristically free intramolecular motion of silicon polymers). The trends of these effects oppose each other in the CSiGeSn series, and so limit the observed increase of viscosity.


We show that for any coprime integers λ1, . . ., λ k and any finite A ⊂ $\mathbb{Z}$ , one has
|\lambda_1 \cdot A + \cdots + \lambda_k \cdot A| \geq (|\lambda_1| + \cdots + |\lambda_k|)|A|- C,
 where C only depends on λ1, . . ., λ k .


From cutting experiments process parameters have been estimated to be input for a sequently coupled temperature-displacement finite element analysis. The cutting process parameters are the primary cutting force, the feeding force, the passive force, the cutting speed, the depth of cut, the unreformed chip thickness, the chip compression and the contract lengths on both rake face and wear land. The volume heat sources in the primary, secondary and tertiary deformation zones can then be calculated. A two-dimensional finite element model has been used. Due to the mass flow of workpiece/chip, forced convection finite elements are introduced. The temperature distribution of the tool has experimentally been estimated based on the method of micro-structural changes of the binder phase. Good agreement with the finite element analysis has been achieved. The temperature distribution have then been used in a stress analysis of the tool where thermo-elasticity and traction loads have been used. High compressive stresses have been found on the rake face, parallel to the cutting edge due to the inhomogenous temperature distribution and the traction loads. Low or no tensile stresses at all were found on the rake face as well as on wear land. The comb crack formation of cutting tools can be the result of the high compressive stresses.


Lagrange multiplier methodalso known as λ-iteration method has been in use to find the solution of the economic load dispatch problem for many years. Though it produces results with great accuracy but it suffers from the disadvantage of convergence as it is highly sensitive to the initial value of λ and at times takes more time to produce results. To overcome this drawback, in this paper an innovative technique to solve the ELD problem, by hybridization of artificial neural network (ANN) and LMM is proposed. To formulate the problem, generation cost is expressed as a function of active power by exponential functions. The equality constraint of power balance and inequality constraint that fix the maximum and minimum active power are duly considered. ANN trained by backpropagation algorithm is used to find the optimal value of λ which is then used to find solutions using LMM. Training data, i.e., input and target patterns for ANN are obtained by LMM. Using proposed hybrid method, λ-iterations are eliminated and promising results are obtained in much less computation time. Hence, the proposed method can be useful in real time solution for seeking online solution of ELD problems.


the theory of atoms by which these facts are explained is by no means of importance to the present inquiry. It is by means of a series of numbers computed according to the method of Richter, that this scale is constructed so as to answer at one view the very numerous questions that occur to an analytic chemist in the examination of any saline compound. It is similar in principle to the common sliding rule, and like that instrument has the usual Gunter's line of numbers on the slider; but upon a line adjacent to the slider are marked certain points corresponding to those numbers which repre sent the various chemical elements, acids, alkalies, and other com pounds intended to be included in the present view. By motion of the slider any one point of the line of numbers, as 100, may be made to correspond with the point indicating any compound, as sulphate of potash. By the position of the point for sulphuric acid, this salt is seen to contain 46 of acid, and the other ingredient potash at the same time corresponds with 54 on the slider. By the position of the point for sulphate of barytes, it appears that 135 of this pre cipitate would be obtained from 100 of the salt, and in the same manner that it would yield 17 6 of sulphate of lead, with a great variety of similar answers respecting the equivalent quantities of other compounds in which the same quantities of acid or neutralizing base is contained. Since the line of numbers is so divided that a given space of every part of it corresponds to numbers that bear a given ratio to each other, and since the intervals on the adjacent column of equivalents are all laid down according to certain given portions of the same scale, they directly indicate by juxtaposition numbers that are in the same proportion on any part of the scale that may be presented to them, as will be very evident to those who are acquainted with the common properties of other sliding rules. For the sake of those who may not be accustomed to the use of the sliding rule, and for the purpose of recommending that valuable instrument to more general use, the author enters rather more than might otherwise be requisite into the elementary principles of logometric division.


New treatment of congenital cleft lips and palates are difficult to choose because the results cannot be fully appreciated before full growth of the child has occurred. For more than 25 years we have closed the lip at 6 months and the palate at 18 months. The latter operation, however, requiring an extensive undermining of the mucous membrane of the hard palate, may retard the growth of the maxilla and induce secondary problems, including crossbite. A new technique, devised by R. Malek, is now used in our department: closure of the soft palate at 3 months of age, and closure of the hard palate in continuity with closure of the lip at 6 months. This new sequence of operations require more skill than the former, but it is satisfactory as the operations are completed at the age they were previously started. A longer follow up will be necessary to evaluate this method, but fewer secondary deformations are expected as it involves minimal undermining and thereby creates less scarring and less growth retardation of the bones.


We investigate the utility of pre-existing question answering models and data for a recently proposed relation extraction task. We find that in the low-resource and zero-shot cases, such resources are surprisingly useful. Moreover, the resulting models show robust performance on a new test set we create from the task's original datasets.


Due to the heterogeneous networks, devices, and user preferences different versions of a source video concerning resolution, frame rate, etc. are required to be generated. Transcoding is the process of converting video file from one format to another format, which is a time-consuming and challenging task. A large-scale cluster of transcoding servers is necessary for video transcoding of a large number of on-demand videos. In addition, a large amount of space is required for storage of multiple transcoded versions. Cloud computing presents a scalable framework for online video transcoding and infrastructure as a service (IaaS) cloud provides virtual machines (VMs) for creating a dynamically scalable cluster of servers. We propose a cloud-based multicore heterogeneous scheduling framework for allocation of different types of video to different types of VMs by extending the existing work on heterogeneous multicore scheduling such a way that the efficiency of the cloud based transcoding system is improved. Further we improve the proposed model by incorporating QoS requirements of video transcoding where video delay and video rejection are reduced to almost zero. The experimental results reveal that the proposed model achieve nearly 100% throughput maintaining high quality of the video by reducing video delay to almost zero.


It is a common observation that the actual functioning of the federal system in any country does not depend on the written constitution and the general legal framework but on the various factors, which influence the political process in the country. Among these factors all writers have assigned an important place to political parties. Political parties are indispensable for proper functioning of democracy. In fact, the modem representative government cannot work without political parties. Nearly all the modem societies have some kind of party system, be it one-party, two-party or multi-party system. It is only means through which power is obtained and exercised in an organized way. The political parties thus appear to be the 'arteries of the body politics'.


student, but in a manner that will satisfy the critical psychologist as well. We are encouraged to learn that many graduate students have used our book to help them prepare for their doctoral examinations, but that is a secondary consequence of responsible writing. Psychology is moving ahead rapidly, and we cannot rely on the same kind of literature searches that served in the past to keep us abreast of contemporary developments. In fact, the three of us, despite the breadth of our interests, cannot possibly be alert to all the new frontiers that are being crossed. Hence we have sought help. Two colleagues prepared specified chapters. Daryl J. Bem, now at Cornell University, revised his chapters on Social Psychology and Psychology and Society for this edition, and Edward E. Smith of Stanford University prepared essentially new chapters on Remembering and Forgetting and Language and Thought. We welcome this new collaborator. In addition, more teachers than ever before prepared reviews of chapters they taught using the previous edition. These were at hand in advance of undertaking the revision, so that new perspectives and data could be included in the rewriting. The 70 or so teachers who did this for us are listed in the Acknowledgments. Several more reviewed the entire previous edition for us. Then, after chapters were revised, they were reviewed in their semi-final form by experts in the particular areas covered. The 50 individuals who served in this manner to check for clarity, accuracy, and contemporaneity are also listed. We are grateful to all who provided help. The logistics of coordinating so many reviews was a major task for our editor, but it was critical to the quality of the final product. Psychology is an unfinished science, and to insist on a single viewpoint throughout would deny the student familiarity with the choices that still lie before psychology Although we accept an eclectic position without embarrassment, we have avoided a vapid eclecticism, in which "anything goes," by introducting five approaches to the study of psychology: neurobiological, behavioral, cognitive, psychoanalytic, and phenomenologicalihumanistic. A consideration of alternative approaches provides a cohesive framework for examining a wide array of different phenomena and the theories that explain them. We do not believe that "covering the ground" is a significant goal for an introductory course. The whole book does indeed attempt to cover the ground, but we believe that teachers can use a block-and-gap method, in which a few topics are covered in greater depth, depending on the time available, the student clientele, and the instructor's preferences. To that end, chapters are relatively complete in themselves, although reflecting the common threads that run throughout the book. Unassigned chapters are there for the interested student to read, so that, even if all are not assigned, the alert student will know that there is more to psychology than what has been emphasized in the course as it was presented.

Temperature has become an important design constraint for high-performance microprocessors. Research on temperature-constrained microarchitecture requires an efficient modeling of temperature. We propose an analytical model of temperature, based on solving a boundary-value problem of heat conduction. The model gives steady-state and transient temperature at any point on the dissipating plane, assuming rectangle-shaped surface sources. The model can be used to reason about temperature. It can also be implemented in a performance/power microarchitecture simulator. We provide two examples illustrating these uses. Key-words: Microprocessor temperature, analytical model, steady state, transient, principle of superposition, point source, rectangle source, method of images


SiC power devices have matured to a point where the development of specific power modules for electric power conversion and distribution and is feasible. Using SiC power devices (MOSFETs and Diodes in 1.2 kV to 10 kV ratings) will reduce total losses (switching and conduction) by about 50% or more depending upon the breakdown voltage rating when compared to an equivalent Si IGBT/PiN diode solution, resulting in efficiency gains of several percentage points. In addition, SiC devices can safely work up to a junction temperature of 190oC with conventional packages. The combination of reduced losses and higher temperature capability will reduce cooling requirements by as much as a factor of six.


Radiotracer /sup 67/Ga-citrate is used as a tumor-seeking agent in clinical imaging investigations although fundamental reasons for its high uptake in certain malignant lesions remain unexplained. The mechanism by which /sup 67/Ga becomes concentrated in tumor cells has been investigated by comparing /sup 67/Ga and /sup 59/Fe uptake by cultured mouse myeloma cells with particular reference to uptake stimulation by transferrin. Concentrations of human transferrin down to 2 microgram/ml greatly stimulated cellular uptake of both tracers, whereas bovine transferrin proved relatively inactive. The rates of stimulated uptake of both tracers were similar as was their high degree of retention by cells, but their quantitative dependencies on transferrin concentration showed characteristics differences. Pretreatment of human transferrin with saturating amounts of nonradioactive Fe/sup 3 +/ canceled its ability to promote /sup 59/Fe uptake, but it had little effect on its promotion of /sup 67/Ga uptake. Further increase in the amount of added Fe/sup 3 +/ did cause a progressive depression of /sup 67/Ga uptake, but this effect probably relates to the iron distribution in the whole-cell culture system including the fetal calf serum component of cell growth medium. The results suggest that /sup 67/Ga and /sup 59/Fe reveal different aspects of themore » interaction of transferrin with cells.« less


In order to reduce the waiting time of customers in the current banking system,a queuing theory based optimization model of banking queuing system was developed.The process of conducting service at the bank counters was regarded as random service system.A detailed design of bank counters' optimization was given based on the basic features of this system.Additionally,a concrete analysis of the system optimization using queuing theory according to two respective aims was presented,and then a new way to decide the appropriate number of bank counters was illustrated with an example.


One of our observations in this lessons learned paper is that there is underwhelming faculty development related to scholarship other than on how to submit and sometimes how to write proposals. This de facto service model misses everything outside of the proposal-writing process; which is the least important, but is often the most celebrated, rewarded, and supported phase. Inspired by national Centers for Teaching & Learning, and modeled after the emerging Communities of Transformation literature, we are piloting a Center for Transformative Research at Boise State University. The vision of our Center is to build and sustain an ASSERTive community -- for Aligning Stakeholders and Structures to Enable Research Transformation (ASSERT). Faculty members from across campus were recruited to participate as fellows to explore what it means to be a scholar and how to move a bold and transformative idea forward. To minimize the energy to apply, the application process included an Instagram post, Twitter response, and/or haiku. Fifteen faculty were selected for the cohort of fellows. To ensure university-wide accountability, a memorandum of understanding was signed by each fellow, as well as their Provost, Vice President for Research & Economic Development, College or School Dean, and Department Chair. Once signed, each fellow was asked to complete a survey and participate in an individual structured interview with the PI and co-PI. These allowed us to determine the specific needs of each fellow, providing validation or perhaps challenging our a priori observations of risk inhibitors at Boise State that prevent germination of bold ideas. By studying the fellows, we were able to look at what may inhibit them from taking risks – personal attributes and beliefs, and structural and cultural issues within their academic units, the university, and in their academic fields. Based on the survey results and individual structured interviews, programming was developed and tailored to the needs of the fellows. An off-campus retreat was held. In addition to the off-campus retreat, on-campus workshops were custom-made for the fellows and included: (a) how to germinate transformative ideas by no longer seeing ideas as precious; (b) how to become an effective collaborator by adapting the Toolbox Project; (c) how to move ideas forward by drawing on the game "Chutes & Ladders" where the chutes represent common obstacles and the ladders are shortcuts; (d)


SEBA is a recently proposed probabilistic identification-free batch authentication solution for RFID tags. It significantly differs from traditional RFID authentication approaches: rather than relying on authentication information delivered by the tags, it exploits the position of the tags' transmissions in response to an authentication challenge. This letter revisits, and meanwhile extends, SEBA. We show that SEBA is a particular case of a more general framework, called SEBA+, which envisions multiple tag responses in a frame. These are in turns interpreted as a Bloom filter, whose authenticity is verified against an authenticator Bloom filter comprising all the deployed tags' computed responses. Our proposed extension significantly improves SEBA's performance when more stringent counterfeit RFID tag detection capabilities are required.


Objective To investigate the State of anxiety and psychological pressure about clinical probationer nurses,analyze the relativity between them ,and provide theoretical basis in order to make distinctive prevention measures for clinical probationer nurses.Methods 216 clinical probationer nurses were sampled by method of cluster sampling from July,2008 to May,2010 in three grade A hospital of Hunan.General datum and psychological pressure of clinical probationer nurses were collected by the self-made Questionnaire,and the anxiety state was measured by Zung SAS.Descriptive analysis and Pearson correlation analysis were done by the use of SPSS 16.0.Results The incidence of anxiety of clinical probationer nurses was 25% in which light degree and middle degree were 19.44% ,and 5.56% respectively.Psychological stress scores among the top three followed by interpersonal aspects were not respected and used as labor,noncooperation and distrust of patients,indifference and stringency of clinical teacher and stange personnel,and the fourth was that their payment did not obtain the approval of clinical teacher in the social aspect.Pearson correlation analysis showed that anxiety of clinical probationer nurses was postitvely correlative with interpersonal aspect (P0.01),social aspect (P 0.01),aspect of work nature and work degree (P 0.01),and aspect of family (P 0.05).The difference had significance in statistics.Conclusions Managers should pay attention to the anxiety state of clinical probationer nurses,give students psychological guidance in time,and lead them to relieve pressure of many aspects by autoregulation.Therefore,anxiety level of clinical probationer nurses was decreased,and their mental health was improved.


Salivary gland memory CD8+ T cells use distinct motility modes and cooperate with tissue macrophages for organ surveillance. Salivary Gland Surveillance Pathogen sensing in tissues is critical to generating rapid immune responses. Within these tissues, macrophages and resident memory CD8+ T cells (TRM) work together to detect pathogens, and Stolp et al. use intravital imaging of submandibular salivary glands (SMG) to show that TRM follow tissue macrophage topology in a dynamic manner. Macrophage depletion is associated with reduced TRM motility and a diminished clustering in response to inflammatory chemokines. However, although SMG TRM respond to chemoattractants, autonomous motility is also observed and is mediated by friction and insertion of cellular protrusions into microenvironmental gaps. These findings demonstrate that SMG TRM can use different motility modes in proximity to tissue macrophages to patrol the tissue microenvironment. It is well established that tissue macrophages and tissue-resident memory CD8+ T cells (TRM) play important roles for pathogen sensing and rapid protection of barrier tissues. In contrast, the mechanisms by which these two cell types cooperate for homeostatic organ surveillance after clearance of infections is poorly understood. Here, we used intravital imaging to show that TRM dynamically followed tissue macrophage topology in noninflamed murine submandibular salivary glands (SMGs). Depletion of tissue macrophages interfered with SMG TRM motility and caused a reduction of interepithelial T cell crossing. In the absence of macrophages, SMG TRM failed to cluster in response to local inflammatory chemokines. A detailed analysis of the SMG microarchitecture uncovered discontinuous attachment of tissue macrophages to neighboring epithelial cells, with occasional macrophage protrusions bridging adjacent acini and ducts. When dissecting the molecular mechanisms that drive homeostatic SMG TRM motility, we found that these cells exhibit a wide range of migration modes: In addition to chemokine- and adhesion receptor–driven motility, resting SMG TRM displayed a remarkable capacity for autonomous motility in the absence of chemoattractants and adhesive ligands. Autonomous SMG TRM motility was mediated by friction and insertion of protrusions into gaps offered by the surrounding microenvironment. In sum, SMG TRM display a unique continuum of migration modes, which are supported in vivo by tissue macrophages to allow homeostatic patrolling of the complex SMG architecture.
