Human emotion is closely related to multiple distributed brain regions, and functional connections exist between the regions. However, how to abstract the region-level information to improve electroencephalograph (EEG) emotion recognition performance has not been well considered. To address this problem, we proposed a novel Adaptive Hierarchical Graph Convolutional Network (AHGCN), which includes the basic channel-level graph of EEG channels and the region-level graph of brain regions. Different from previous methods, we propose an adaptive pooling operation to automatically partition brain regions rather than manually define them. To capture the intrinsic functional connections between the brain regions or EEG channels, we design a gated adaptive graph convolution operation. Besides, we develop a graph unpooling operation to integrate the region-level graph and channel-level graph to extract more discrimination features for classification. Experiments on two widely-used datasets show that our proposed method is superior to many state-of-the-art methods on EEG emotion recognition and could find some interesting combinations of EEG channels.


Abstact: A new method for accounting for quantum effects in semiclassical device simulation is presented. The approach is based on the solution to the Boltzmann/Wigner equation, which is derived from the Schrodinger equation. The Boltzmann/Wigner equation is formulated using spherical harmonics. This facilitates analytical evaluation of the collision integral, and allows for reduction of dimensionality. The Boltzmann/Wigner equation is solved self-consistently with the Poisson and hole-current continuity equations for a BJT and a MOSFET. The results show that the carrier concentrations predicted by the Boltzmann/Wigner equation near the base-emitter junction and the MOSFET channel are less than that predicted by the semiclassical Boltzmann model. Calculations show terminal currents to be 2% and 7% lower for the quantum simulations than the semiclassical results for the BJT and MOSFET, respectively.


. Healthy or good quality soils are essential for ecosystems to remain intact or recover from disturbances. Soil quality is soil-and site-specific and can vary according to controlling factors, such as inherent soil properties. The research proposal was conducted in 2015-2016 to study soil physio-chemical properties across seven elevations and the River Swat catchment area between Barikot and Topsin in Swat-district, Pakistan. The sampling date was March 11-12, 2016, to better evaluate soil classification. Soil samples were collected and analyzed for their physicochemical properties, including surface, sub-soil, and sub-strata. The data showed that silt content decreased, and clay content increased with altitude, while sand content showed inconsistent variation. Bulk density, lime content, electric conductivity, and pH decreased, while concentrations of nitrogen (N), phosphorus (P) and potassium (K), and micro-nutrients increased. Soil organic matter (SOM) content significantly increased (P<0.05) as the altitude increased. Soil samples were non-saline (EC<4 dSm -1 ) and slightly calcareous (lime content 2.34% to 5.32%). Higher altitudes increase micro-nutrient content and water retention, while lower elevations decrease water retention. We found that crop available P in all selected sites along the altitude were deficient, classified as P deficient soil. All physicochemical properties were within the range of crop demands, so sustainable management practices are needed to build soil P levels that meet crop requirements.


Paroxetine is the second most prescribed selective serotonin reuptake inhibitor (SSRI) antidepressant drug, characterized by extensive inter-individual variation in steady state plasma concentrations resulting in drug toxicity amongst patinets. A nanopolymeric biosensor for studying the biotransformation of paroxetine is presented. The bioelectrode system consists of cytochrome P450-2D6 enzyme encapsulated in nanotubular poly (8-anilino-1-napthalene sulphonic acid) electrochemically deposited on gold. The biosensing procedure involved the determination of the extent of modulation of fluvoxamine responses to the P450-2D6 enzyme electrode after incubation in paroxetine standard solutions. Paroxetine inhibited the activity of cytochrome P450-2D6 (CYP2D6) resulting in a decrease in the fluvoxamine signal of the biosensor. The biosensor gave a linear analytical response for the paroxetine in the interval 0.005 and 0.05 μM, with a detection limit of 0.002 μM and a response time of 30 s. Electrochemical Michaelis–Menten kinetics of the reversible competitive inhibition of the fluvoxamine responses of the biosensor by 0, 0.05 and 0.1 μM paroxetine gave apparent Michaelis–Menten constant (KMapp) values of 1.00 μM, 1.11 μM and 1.25 μM, respectively. The corresponding value for the maximum response, IMAX was 0.02 A. The dissociation constant, KI, value evaluated from Dixon analysis of the paroxetine modulation data was estimated to be-0.02 μM while Cornish-Bowden analysis confirmed the competitive inhibitory characteristics of the enzyme.


Raw materials have larger effect on the quality of high strength fastener for wind electricity machine units. The effects of raw material quality on high strength fastener are expounded from seven aspects of appearance quality, chemical composition, low-magnification structure, decarbonization layer depth, non-metallic inclusion, microstructure and cold heading test. The center loosing, general loosing and squire segregation of high grade qualified steel such as medium carbon steel and medium carbon alloy steel permit no more than 1.5 grade, do not permit existing such defect as flake, shrinkage cavity, bubble, skull patch. The decarbonization layer of steel used for high strength fastener for wind electricity machine units should not be more than 1% of nominal diameter. The banded structure in medium carbon steel and medium carbon alloy steel take 0 to 3 grade as qualification, Widmannstatten structure is qualified as 0 to 2.5 grade. The premium grade one-third cold heading should be ensured qualification for high strength bolts and nuts for wind electricity machine units.


We investigate the coherent dynamics at the band edge of GaAs at low temperatures for carrier densities ranging from 4.3 × 1014 cm−3 to 4.4 × 1017 cm−3 by means of spectrally resolved transient four-wave mixing with 14-fs pulses. At large nonequilibrium carrier densities we observe oscillations with an energy-dependent oscillation period related to interference among continuum states. The experimental findings are compared with a simple model. This comparison delivers a weak energy dependence of dephasing in the initial buildup phase of screening.

In order to extend the life cycle of the developed oilfield and ensure the stable production of the oilfield, the exploration and practice of supplementary energy refracturing has been carried out in a small block in eastern China which is on the verge of shutdown since 2017. All of the well in this block are vertical wells. This technology breaks the injection production relationship of the original well pattern. The injection wells and production wells are fractured at the same time. Fracturing fluid is not only used for fracturing, but also for supplementing formation energy. In order to produce more new fractures and make them more complex, low viscosity slippery water is used in hydraulic fracturing. It ensures that the material cost is reduced while the amount of fracturing fluid is increased. In addition, the multi-stage proppant combination is used to support all levels of fractures, which improves the conductivity of all levels of fractures. During the implementation of refracturing, the amount of fluid used in single layer is gradually increased, from 2300 to 3500 cubic meters, the maximum amount of fracturing fluid injected in single layer is 10000 cubic meters, and the proportion of slippery water is increased from 80% to 95%. The proppant is composed of 100/140 mesh and 40/70 mesh ceramic proppant, with an average sand content of 97.7 cubic meters per layer. From the perspective of construction data, after increasing the amount of fracturing fluid used in single well, the average pump stopping pressure of the later batch of construction wells is increased by 3.5 Mpa and the construction pressure is increased by 4.5MPa. After adding temporary plugging agent, the average construction pressure increased by 1.8 MPa, and the opening characteristics of new joints were obvious. After refracturing, all test wells are produced by automatic injection production, the total number of automatic injection production days is 5.2 times of the initial fracturing, and the cumulative oil production is 1.5 times of the initial fracturing. Through practice, the original injection production relationship is broken. Increasing the amount of fracturing fluid can not only supplement the formation energy, but also improve the complexity of fractures. The multi-stage proppant slug can significantly improve the conductivity of fractures at all levels, prolong the life cycle of old wells, and provide technical support for multi thin layer reconstruction.


An airborne fourier transform interferometric sounder is being developed to perform atmospheric measurements for the National Polar-orbiting Operational Environmental Satellite System. The interferometer is designed to provide high spectral resolution, low noise data from the NASA ER-2 aircraft suitable for synthesizing and comparing data of potential future satellite-borne sounding instruments, such as AIRS, IMAS, ITS or IASI. The collection and scanning optics provide a 7.5 degree field of view over a cross-track field of regard of +/- 48.2 degrees. The interferometer operates with +/- 2.0 cm optical path difference (OPD) over the spectral range from 3.6-16.1 micrometers . Dynamic alignment is performed using a concentric HeNe laser. Three separate filter/lens/detector assemblies are cooled to 65K using integral rotary stirling coolers. Most of the optical instrumentation is contained within a pressurized N2 enclosure to minimize the effects of descent condensation. The instrument processor/controller is based on a 133 MHz Pentium CPU supporting a dedicated digital signal processor for real-time x16 data decimation. Noise performance referred to a 250 K scene is estimated to be 0.10 K at 14.9 micrometers , 0.15 K at 8.7 micrometers and 0.2 K at 4.7 micrometers .


The application of the formula, which is used to calculate the maximum field at the tip of the pin-plane electrode system was proposed to describe the process of electrical treeing and treeing breakdown in an oil shale.

This work studies sound in the concrete poetry of Grupo Noigandres and Stuttgarter Gruppe, focusing in particular the recordings of poems and the Horspiele recorded in the Sixties. The manifold problems connected with the concrete poetry movement (intended as a whole) is followed by a specific theoretical-methodological section on sound, which clarifies the inclusion of this study in the field of the sound studies and introduces tools for the analysis (phonetics, music, technology). The latter is qualitative, since it focuses specifically on a few recordings, in an attempt to "build" possible meanings of the hearable sounds, and especially to consider the importance of the impact on the body for better understanding the esthetic experience of listening that concrete poetry provides. By focusing on sound, this study aims to return the body to concrete poetry, its physical presence and materiality, whose importance has too often been diminished by critics concerned exclusively with the graphic-visual aspect and interested in the mere attribution of "right" meanings. This comparative approach reveals of some common aspects between two extremely important schools within the context of concrete poetry, which however only rarely engaged in dialogue regarding poetic composition, and even less in regard to their respective relationships with sound and the esthetic experience that it produces.


Present energy situation of the world is unsustainable due to unequal geographical distribution of natural wealth as well as environmental, geopolitical and economical concerns. Ever increasing drift of energy consumption due to growth of population, transportation and luxurious lifestyle has motivated researchers to carry out research on biofuels as a sustainable alternative fuel for diesel engine. Biodiesel seems as one of the best choices among other alternative fuel sources due to its renewability, cost effectiveness and reduction of pollutants in exhaust gas emission which are promoting biofuels as a suitable substitute of diesel fuel in near future. This research endeavor aims to produce and evaluate the comparative performance and emission of palm, mustard and Calophyllum inophyllum biofuels in a four cylinder diesel engine. This was followed by the production of palm, mustard and Calophyllum inophyllum biodiesel from their respective oils and blending them with diesel fuel. Detailed characterization of physicochemical properties of pure biodiesel and their blends meet standard ASTM specifications. Engine performance and emission were evaluated by measuring brake specific fuel consumption (BSFC), brake thermal efficiency (BTE), engine power, engine torque, carbon monoxide (CO), hydrocarbon (HC), and nitric oxide (NO) emission. The results of engine performance revealed that biodiesel blended fuels produced average reduction in engine BTE, power and torque with increased BSFC. In case of engine emission, biodiesel blends showed an average reduction in CO and HC with a slight increase in NO & CO2 emission. Overall, Calophyllum inophyllum biodiesel blends showed better engine performance and emission compared to palm and mustard biodiesel blends. The peak cylinder pressure and heat release of biodiesel blends were found higher and closer to top dead centre compared to diesel fuel. This is due to the shorter ignition delay and higher cetane number of biodiesel.
In conclusion, palm, mustard and Calophyllum inophyllum are potential feedstock for biodiesel production and up to 20% of their blends could be used in the diesel engine without any modification. Besides, as producing biofuel from edible oil source has received criticism worldwide, therefore using non-edible vegetable oils like: calophyllum as biofuel can replace the current dependence on the edible oil source.

PURPOSE: To measure the density of a gas by detecting a measurement signal by using a single electrically synchronizable short resonator Fabry-PeProt interferometer, in a bandpass process using two passband wavelengths in a condition that the measurement signal from the radiation source is sent toward an object to be measured. CONSTITUTION: A radiation source 1 emits a wide-area spectral radiation. The radiation is propagated through a measurement channel to Fabry-PeProt interferometer 5 acting as a filter. A wavelength having passed through the passband of the filter element, is entered into a cut-off filter 7. Only the wavelength longer than a specific cut-off wavelength, is passed through the cut-off filter 7, and the intensity of the wavelength beam is detected by a detector 9. The length of a measuring channel 3 is selected from the wide extent, and the design of the same is decided by the density of the gas to be measured, and the absorption property. The detector 9 is a pyroelectric detector or the like, selected corresponding to the extent and intensity of the wavelength to be used, and the filter 7 has the function of a detector cover inlet window.


»Eine Faust auf dem Titel. Einige Bemerkungen zu visuellen Quellen in der Sportgeschichte«. Visual sources are extremely important for the understanding of the development of modern sports. Images in magazines, newspapers, books, collecting cards, and all the paraphernalia pertaining to sports shape the collective notion of what sports means and which values are connected with it. This article about a specific image which made a cover of the leading French sports magazine La Vie au Grand Air in 1908 explores the possibilities of historical analyses of media coverage in sports including images. The content of an image, its immediate and wider context including iconographic traditions and conventions and how they work together are taken into consideration. The special character of photographs in the media makes them pivotal for the contemporary promotion of sports and the specific way to imagine concepts of a modern body around 1900 and beyond as an outdoor activity and way of life.


The proteome of lysates of the breast tumor cell lines MCF-7, BT-474, and ZR-75-1 was mapped, resulting in the sequence of 340 proteins. The proteins associated with the biosynthesis of PGE2 and with the regulation of cyclooxygenase-2 expression were identified and their relative expression levels were determined. Potential goals for the targeted therapy of breast cancer, such as prostaglandin E2 and D2 receptors, pros- taglandin E synthase, 15-hydroxyprostaglandin dehydrogenase and leukotriene-A4 -hydrolase, are of special interest in this group.

Abstract Abnormalities in one or more serial liver function tests occurred in twenty-three of twenty-four cases of infectious mononucleosis. Sixteen cases showed changes in three or more tests. Elevated cephalin-cholesterol flocculation and thymol turbidity values were found in 79 and 83 per cent of the patients respectively. Abnormal bromsulfalein excretion was demonstrated in 71 per cent, and the alkaline phosphatase was elevated in 38 per cent of those tested. The maximum number of changes was observed during the second and third weeks of disease. Altered cephalin flocculation and thymol turbidity reactions were the most persistent abnormalities, lasting more than two months in a fourth of the patients. The occurrence of abnormal liver function tests was not correlated with the signs and symptoms of hepatic involvement or with the height of the heterophile antibody titer. Composite serial studies indicate that approximately two-thirds to three-fourths of patients with infectious mononucleosis have hepatitis.


Abstract To investigate corrosivity characteristics of tap water in Kore a, Langelier index (LI) of 30 multi-regional water treatment pl ants(WTPs) were evaluated. Weekly LI values of 30 WTPs were all neg ative, which means tap water in Korea might be very corrosive.Maximum LI decrease through water treatment processes was 0.95 under no additional corrosion control process. Based on thecorrelation results between LI and tap water qualities, pH and calcium concentration were confirmed as major parameters for LIcontrol. Addition of calcium hydroxide with CO 2 or calcium hydroxide or sodium hydroxide can be chosen based o n water quality.Continuous monitoring of LI and related parameters is recommend ed in water distribution system.

Catalysts containing Ni or combinations of Pd, Cu and Zn on gamma alumina support have been developed for testing in autothermal methanol reforming reaction. The hydrogen produced by the catalytic reforming of methanol is targeted to be used as a feed for fuel cell. The reaction for reforming of methanol can be performed at low temperature and pressure in the presence of catalysts with high yield and low CO. The calcined catalysts has been characterized by Brunauer, Emmett and Teller (BET) for surface area, Scanning Electron Microscopy (SEM) for shape and dispersion of metals, Powder X-ray diffraction (XRD) for species present and degree of crystallinity and Temperature Programmed Reduction (TPR) for reducible species presence, their interaction and degree of reducibility. The catalyst has specific characteristic in physical and chemical properties due to the location of Ni metal on the surface of the ?-Al2O3. The effects could be observed in colour, SEM, and the total number of pores of the catalyst. The amount of metal in the supporting material ?-Al2O3 also influenced the physical properties of the catalysts. From the catalyst produced with various concentration, it is found that the content of Ni metal with specific amount, fill the channels on the surface of supporting material ?-Al2O3. Based on the catalyst activities data, suitable catalyst to produced hydrogen can be formulated.


Analytical pretreatment has become environmental-friendly because of material science assistance. In stir bar sorptive extraction (SBSE), a coating is typically used to isolate and preconcentrate organic compounds in aqueous samples. Here, a translucent coating based on polydimethylsiloxane and phenyltriethoxysilane was prepared by a sol-gel method. Characterization tests showed that the coating was homogeneous, relatively polar, and both thermally (< 400 °C) and chemically stable. Coated stir bars were evaluated in the SBSE experiments. Benzene derivatives were successfully extracted/preconcentrated from aqueous solutions and environmental waters. Furanic derivatives and antibiotics were moderately extracted from water, but they were extracted from isooctane.


Embedded systems are pervasive in the infrastructure of our society for diverse tasks such as studying environmental phenomena, mapping and managing large-scale systems, aiding security and other fields, but masses of them do not have the capacity of network interconnection, these greatly limits the use of equipment, control and data exchange performance, therefore we proposed an method of embedded system interface based on Ethernet which combined with the latest computer technology, network technology, communication technology. We introduce the Ethernet technology and embedded system theory, using Ethernet controller CS8900A and S3C2410_net to design the Ethernet interface module, while given the system flow chart. The system interface will widely use in various applications and has good prospects. Embedded systems are pervasive in the infrastructure of our society for diverse tasks such as studying environmental phenomena, mapping and managing large-scale systems, aiding security and other fields [1]. And market demands for innovative, high quality products, aggressive competition at a global scale, increasing productivity through highly optimized production processes, and environmental/societal pressures are some of the challenges faced by the manufacturing industry today [2]. Rapid changes in process technology demand production systems that are themselves easily upgradeable, and into which new technologies and new functions can be readily integrated [3]. While Ethernet is the most widely used LAN technology, it can conveniently set up Ethernet LAN and access to the Internet [4]. With the development of embedded operating systems and platforms, embedded controllers, smart field instrumentation and sensors can be easily access to Ethernet control network. Using technology for embedded systems, it enables Ethernet communication directly to the scene device level. The Ethernet access to embedded systems usually have two kinds of method: First, using the embedded processor of integrated Ethernet interface; second, embedded processor is used with Ethernet controller chip [5].the former requires embedded processor has general network interface, usually it was designed for network application and embed the curing network protocol in internal, processor and network rapidly exchange data through the internal bus, but the curing network protocol in internal can easily use in different occasions, but it easily generate unnecessary waste and the cost is relatively high. The later, has not special requirements and only connect the Ethernet control chip to the processor bus, but processors and network exchange data through the external bus (usually a parallel bus),it will slow network speed and the reliability is not high [6]. In this …


chemical sensor arrays eliminate the need to develop a high-selectivity material for every analyte. The application of pattern recognition to the simultaneous responses of different microsensors enables the identification and quantification of multiple analytes with a small array. Maximum materials diversity is the surest means to create an effective array for many analytes, but using a single material family simplifies coating development. Here the authors report the successful combination of an array of six dendrimer films with mass-sensitive SAW (surface acoustic wave) sensors to correctly identify 18 organic analytes over wide concentration ranges, with 99.5% accuracy. The set of materials for the array is selected and the results evaluated using Sandia`s Visual-Empirical Region of Influence (VERI) pattern recognition (PR) technique. The authors evaluated eight dendrimer films and one self-assembled monolayer (SAM) as potential SAW array coatings. The 18 organic analytes they examined were: cyclohexane, n-hexane, i-octane, kerosene, benzene, toluene, chlorobenzene, carbon tetrachloride, trichloroethylene, methanol, n-propanol, pinacolyl alcohol, acetone, methyl isobutyl ketone, dimethylmethylphosphate, diisopropylmethylphosphonate, tributylphosphate, and water.


The synthesis of 5- to 8-memebered cyclic thioethers 4 has been achieved through a simple two-step sequence. The present methodology utilizes the facile Friedel-Crafts acylation of terminal alkynes 1 with acid chlorides 2 followed by tandem C(sp(3))-S and C(sp(2))-S bond formations with NaSH.xH(2)O.


The effective use of quinidine as an antiarrhythmic agent is frequently curtailed by one of its most common side effects—relentless diarrhea. Seven patients are described in whom diarrhea was quickly and completely controlled by the use of cholestyramine resin. To date, this is the only therapy reported to be effective for this purpose. It has proven to be safe, well tolerated, and continuously effective in these cases.


Governments and their agents can both facilitate and constrain organizational wealth creation. Whilst heterogeneously distributed valuable political resources allow a firm to develop capabilities to gain competitive advantage, less attention has been devoted to the conditions that impact the development of political capabilities in varying institutional contexts. This qualitative, inductive study examines the development and application of political capabilities in five European national airline carriers within an institutional context requiring reactive political strategies to influence policy makers, i.e. avoiding security costs from 9/11. We contribute to capability theory and practice studies by showing how senior management teams develop political capabilities in institutional contexts exhibiting increased uncertainty. We argue that while the senior management's attention to specific political processes can create valuable political capabilities, this value creation is moderated by the nature of the ...


Introduction: Electrodeposition has a major advantage over other methods of thin film deposition. It allows one do it at atmospheric pressure and room temperature, requiring relatively inexpensive equipment. [1] The Hull cell is a miniature electrodeposition tank where the cathode is angled with respect to the anode. The resulting current density will vary along the length of the cathode surface. [2] That way, it is possible to obtain an optimal plating distance for certain given parameters of the system. There are, normally, practical problems if a semiconductor cathode is used. A full backcontact has to be provided to avoid different deposition rates due to the high resistivity of a doped semiconductor substrate compared to a metal cathode. Furthermore, an electrical non-conductive holder is used to prevent deposition other than through the front opening where the cathode has its interface with the electrolyte. It is expected that the current lines in the plating cell will be changed and trying to minimize that the holder opening for the cathode was made as central and as large as possible. Use of COMSOL Multiphysics: 2and 3-D electrodeposition finite element simulations of a 250 ml Hull cell with soluble copper anode were done to obtain the current density along the cathode surface. The silicon chip holder is also added to the simulations in order to analyze its influences to the experiment. Results: The electrolyte current density vectors inside the Hull cell are shown in Figure 1. After normalizing the results from the simulation [3] a comparison is shown in Figure 2. The current density vectors for the Hull cell using the chip holder can be seen in Figure 3. Conclusion: The experiments with the Hull cell and the chip holder were realized and the simulations have shown similar results. A modified Hull cell design will be suggested for further experiments. The simulation of the new setup will also be shown.


Radial velocities and central velocity dispersions are derived for 238 E/S0 galaxies from medium-resolution spectroscopy. New spectroscopic data have been obtained as part of a study of the Fundamental Plane distances and peculiar motions of early-type galaxies in three selected directions of the South Equatorial Strip, undertaken in order to investigate the reality of large-scale streaming motion; results of this study have been reported in Muller et al. (1998). The new APM South Equatorial Strip Catalog () was used to select the sample of field galaxies in three directions: (1) 15h10 – 16h10; (2) 20h30 – 21h50; (3) 00h10 – 01h30. The spectra obtained have a median per of 23, an instrumental resolution (FWHM) of ~ 4 , and the spectrograph resolution (dispersion) is ~ 100 km s -1 . The Fourier cross-correlation method was used to derive the radial velocities and velocity dispersions. The velocity dispersions have been corrected for the size of the aperture and for the galaxy effective radius. Comparisons of the derived radial velocities with data from the literature show that our values are accurate to 40 km s -1 . A comparison with results from Jrgensen et al. (1995) shows that the derived central velocity dispersion have an rms scatter of 0.036 in . There is no offset relative to the velocity dispersions of Davies et al. (1987).


Early music in Australia has a rich and interesting history. Each state boasts a multitude of dedicated performers, many of whom exhibit a musicality and technique that undoubtedly puts some European professionals to shame. One such Australian artist is the Melbourne-based harpsichordist Elizabeth Anderson, who has an established international career as a performer, and has produced eight recordings, several of which have won awards from such august organs as Gramophone, The age and Soundscapes. The convict harpsichordist (Move md 3242), her latest CD, is a remarkable total package. Based around the story of John Grant, the disc comes with a booklet explaining the historical background to the music and story, and contains not only the sound recording, but also an 18minute CD-ROM in which dramatized scenes emerging from Grant's correspondence are presented by actor James Benedict. There is much to like in this release. Anderson is a good enough player to be able to present her musical ideas without the restrictions imposed by technical limitations, and the music is thus vividly brought to life in her interpretations. The instrument is also recorded very well, and the balance between bass and treble is excellent, with a transparent clarity to the middle of the sound that allows the listener to hear exactly what is going on at all times. At a' = 440, the harpsichord, a McAllister/Hubbard after Taskin, sounds quite bright. Perhaps 415 might have been a better choice of pitch for works such as the Soler C minor sonatas (r18 and 19), which come off as a little frivolous here. Of the 11 works selected for this recording, many of the first ten will probably be familiar to fans of the historical repertory. Anderson opens with a virtuoso rendition of Domenico Scarlatti's k386 and 387 sonatas in F minor. This is followed by a very stylish and energetic performance of the Sonata no.10 in D major by Pietro Domenico Paradies; at times the articulation seems a little abrupt, and more use might have been made of suspiratio, but, overall, this is a highly enjoyable version. Next to appear are a matched set of preludes and fugues by J. S. Bach, the first in D major (bwv893) and the second in G major (bwv884). These are played well, but fail to leave a lasting impression, something which can certainly not be said of Handel's Suite no.5 in E major that follows. While this may have been chosen because of the last movement, the famous 'Harmonious Blacksmith' variations, the second and third movements exhibit a control of touch and phrase that borders, at times, on the sublime. This one work alone is worth the purchase price of the disc. Spanish rhythms are evident in Scarlatti's k380 and 381 sonatas in E major, and Anderson brings these out to full effect, as she does the contrast between affective melancholy and fiery virtuosity in the k32 and 33 Sonatas in D minor immediately afterwards. The Spanish theme reappears in the C minor sonatas by Antonio Soler, which are interpreted beautifully despite what seems an inordinate brightness in sound quality. Finally, the 18th-century part of the disc is rounded out with Mozart's variations on Ah, vous dirai-je maman, which here is made to sound surprisingly fresh in an excellent performance that moves effortlessly between the witty, the grand and the tender. The final work is This beauteous wicked place, a contemporary piece by Ron Nagorcka that combines the didjeridu with electronics, Australian bush sounds and a microtonally altered harpsichord that sounds very like a Japanese koto. This effect is heightened by the use of modified pentatonic scales throughout. Though such a work may not be to everyone's taste, it is an excellent example of the genre, and of modern Australian composition in general. It features strong rhythmic elements and melodic cells that create a fascinating musical texture overall. Anderson was also considerate enough to place it at the end of the recording, allowing those who want a purely Baroque experience to avoid it with ease. This being said, it is certainly worth taking the time to listen to the work at least once. When the disc is considered as a musicological document, however, a number of problematic issues become evident. The first of these lies in the justification for the choice of music. Although the story of John Grant, a gentleman who, as the cover tells us, 'shot a London lawyer in the buttock' and was subsequently transported to Australia, is used as an amusing backdrop, there is no proof that he owned any of the works chosen here. Indeed, there is no evidence that he played them or was even aware of their existence, although, to be fair, such a claim is not advanced in the accompanying leaflet. Instead, the rather tenuous basis for the selection of music is that editions of all the 18th-century pieces presented on this disc were available from London publishers such as Longman & Broderip between 1791 and 1803, the former being the year in which Grant became an apprentice to his uncle, and the latter being the year in which he was convicted and transported.


The distinction of slow-flow dural carotid-cavernous sinus fistula from high flow lesions is important both from a prognostic and management point of view, particularly in the elderly. We report the c


Except for corporate taxpayers with revenues exceeding $25,000,000, either method of accounting will likely be acceptable for calculating taxable income. However, it is not acceptable to keep books throughout the year using one method of accounting and then convert at year-end to another method, solely because that second method might provide a more favorable computation of taxable income. A farmer might use a cash basis record keeping system, with subsequent adjustments to generate "accrual adjusted" statements. This would allow him to remain a cash basis taxpayer. But converting to a full accrual basis record keeping system would require that taxable income also be calculated on the accrual basis.


Abstract The crystal structures of 2RbCl·CoCl2·2H2O (1) and 2RbCl·NiCl2·2H2O (2) have been determined by X-ray diffraction analyses. Both crystallize in triclinic space group P 1 with a = 5.596(3), b = 6.486(3), c = 7.009(3) A, α = 65.35(2), β = 87.68(2), γ = 84.58(3)°, Z = 1 for 1, and a = 5.571(2), b = 6.450(3), c = 6.968(2) A, α = 65.52(4), β = 87.57(3), γ = 84.22(3)°, Z = 1 for 2. The Co2+ and Ni2+ atoms are both coordinated in distorted trans-octahedral geometries by four Cl− and two water molecules, and Rb+ is surrounding by eight Cl− ions. The average interatomic distances between the first transition metal(II) and chloride ions in trans-[M(II)Cl4(OH2)2]2- (M(II) = Co, Ni) moieties are 2.479 and 2.437 A for 1 and 2, respectively, and the M(II)-O bond lengths are 2.107 and 2.070 A for 1 and 2, respectively. With the same M(II) cations, the M(II)-Cl distance is significantly longer than those of cis- and trans-[M(II)Cl2(OH2)4] octahedral moieties reported previously in M(II)Cl2 · 4H2O and M(II)Cl2 · ...


As the concluding chapter of the work, this chapter revisits the central thesis of the book, which is the import of the context and constraints of white supremacy on black public opinion formation. Using immigration as a lens to better understand black opinion, the book argues that white supremacy is at the core of black public opinion formation; in this way, it is not an individual story about immigrants or immigration policy. My theory of conflicted nativism helps the reader to understand how and why blacks hold seemingly divergent opinions on the issue of immigration. I am able to show, however, that these opinions are not in conflict. Rather, blacks have distinct considerations as Americans that come from their unique position in the American racial hierarchy and the ways in which white supremacy structures how they navigate an array of political issues. The chapter concludes with a brief examination of border separations, which has animated much of the recent conversation in this policy arena.


"OH, FOR A LANGUAGE TO WRITE DRAMA IN," Eugene O'Neill wrote in 1929. "I'm so strait-jacketed by writing in terms of talk! But where to find that language?"l His cry of frustration reiterated the feelings of one of his French contemporaries, Antonin Artaud (1896-1948). Although O'Neill failed to answer his question, Artaud, in his plays and poems, undertook a long series of experiments in language, sound, and tone in an attempt to develop new means of communication.The Spurt of Blood (Le Jet de sang) (1925), a play which was the highpoint of his early period (1924-1931), demonstrates the subservient role Artaud assigned to language. The work is a montage of short, highly visual episodes. Briefly, the work opens with a love scene between a young couple, which is interrupted by a cosmic convulsion in which parts of human anatomy, temples, and insects fall from the sky. After the storm, the man and girl leave, and then a Knight and Nurse enter. Following their sexually suggestive actions and discussion, the ...


HIV (human immunodeficiency virus) is a lentivirus that causes acquired immunodeficiency syndrome. It is a condition in humans in which progressive failure of the immune system occurs. Antiretroviral therapy is used for treatment and prevention of HIV infection. Widespread use of antiretroviral agents and increasing occurrence of HIV strains resistant to these drugs has given rise to a number of important issues. There is no drug to cure HIV. To prevent drug resistance combinations of antiretroviral drugs are given. Antiretroviral therapy has been shown to prolong survival in persons with acquired immunodeficiency syndrome (AIDS) and those with intermediate-stage human immunodeficiency virus (HIV) infection.


Until recently, employers supported restrictions or bans on smoking primarily to prevent fires, protect equipment, or avoid product contamination (81). In a few instances, restrictions or bans were imposed because of demonstrated synergy between smoking and a worksite exposure to a product that increased risk of lung cancer, such as asbestos. That rationale was used by Johns Manville Company when, in 1977, smoking was banned and smokers were no longer hired (22, 26). Based on comparable patterns of demonstrated synergy, a similar rationale could also apply to workers exposed to ionizing radiation and some occupational chemicals (68). In 1979, the National Institute for Occupational Safety and Health described the interaction of cigarette smoke with numerous occupational exposures and summarized six mechanisms by which these interactions occur (9). In recent years, protection of employee health through reduction of expo-


Of the 20 cases now recorded of hepatic tumors occuring in patients treated with androgenic steroids 15 have been in patients with aplastic anemia; 10 of these patients have had findings compatible with Francoinis anemia. This is a report of a 6 1/2 year-old girl who had Franconis anemia and hepatic neoplasia. She was also noted to have mild microcephaly thumb abnormalities and multiple chromosomal breaks. After 2 months of oxymetholone therapy (4.5 mg/kg/day) hepatomegaly and fever developed. A mass was detected in the right lobe of the liver and multiple nodular densities in both lung fields. The alpha-fetoprotein determination was negative. An open liver biopsy showed hepatocellular carcinoma. The patient died of the rapidly progressive cancer. The association between the androgen therapy and the malignant hepatic tumor is suggested.


Surface modification of textile materials is of major importance in the modern textile industry. Several methods are commonly applied to produce a broad range of coated materials. The adhesion between the coating polymers and the textile fibers often determines the quality. Improved adhesion of the coating is achieved by a chemical bonding (covalent or ionic) between the coating materials and the textile. The efficiency,however, is dependent on the orientation of the functional groups of the outmost molecular layers of the fibers. Therefore, we have used surface sensitive methods to analyze the surface structure of proteinaceous fibers. Homopoly(aminoacid) films like poly(-(gamma) -benzyl-L-glutamate) and poly(- (Beta) -benzyl-L-aspartate) have been chosen as models for natural fibers like wool.


The effect of methanolic extracts of Achillea millefolium and Teucrium polium on third instar larvae of Egyptian cotton leafworm, Spodoptera littoralis were investigated. Methanolic plant extracts were mixed with artificial diet and then nutritional indices, glutathione-S transferase, esterase, α-amylase and protease, activity were measured 72h later. Approximate digestibility was increased significantly in larvae fed on the food containing methanolic extract of T. polium but there was not any significant change in insects treated with A. millefolium. T. polium significantly decreased relative growth rate (RGR), relative consumption rate (RCR), efficiency of digested food (ECD) and efficiency of conversion of ingested food (ECI) whereas A. millefolium only decreased RGR and RCR. Feeding on artificial diet containing plant extract decreased α-amylase and protease activities in the midgut of the insect. Furthermore, the effect of methanolic extract of plants on detoxifying enzymes showed that they have no effect on glutathione Stransferase and esterase activities.


Traditionally, the relationship between the body and the right has been approached from the positive instance of the law. To that extent, the body becomes a surface on which penalizes the crime evident truths. Contrary to this perspective, this article aims to rethink the importance of expanding the dialogue with other knowledge law so that opens a thoughtful way to interpret their exercise and introduce another way of studying the body and the complexities around same weave.


The effect of photo-induced enhancement (more than a tenfold) of room temperature deep-trap photoluminescence (PL) in CdSe quantum dots (QDs) embedded in polyvinyl alcohol (PVA) film has been found and investigated by the PL and X-ray diffraction methods. The effect is observed under illumination of the QD/PVA composite with LED's light of 409 or 470 nm at elevated temperatures and is shown to be caused by an increase of the activation energy of thermal quenching of defect-related PL. It is shown that thermal annealing of the composite by itself stimulates polymer crystallization and produces a small increase in the intensity of both the band-edge and defect-related PL bands of CdSe QDs. It is found that the effect of ◦ ◦ uantum dots olyvinyl alcohol hotoluminescence -ray diffraction illumination decreases when the annealing temperature increases from 90 C to 120 C because thermal annealing at 120 ◦C per se results in strong enhancement of room temperature deep-trap PL. The effect of photo-induced enhancement of defect-related PL is found to be irreversible and is assumed to be related to the change of QD surface defect passivation or surface defect rearrangement. This is ascribed to partial destruction of PVA matrix as a result of interaction of QD/PVA interface with photocarriers generated in the QDs due to LED's light absorption.


My association with the University of Iowa Department of Obstetrics and Gynecology began over 30 years ago as a fourth year medical student when I did a rotation on the High Risk Antepartum service. The University provided visiting medical student housing at West Lawn. I returned the next July to start my Residency. The next four years trained me well. My teachers/mentors were experts, including Board examiners, textbook and journal editors, and a President of the American College of Obstetricians and Gynecologists (ACOG). My fellow residents were well trained, and some have become Board examiners, textbook and journal editors, and one became the President of ACOG. Since completing my residency, I served four years in the United States Army, then I returned to join my current practice in Dubuque, IA. I have regularly attended the OB/GYN Postgraduate meeting each fall and have been impressed with the visiting speakers at this annual meeting. I learn something valuable for my clinical practice each year.


What really constitutes 3-D data? How complete does the package of technology have to be in order to earn the label 3-D? The commonly accepted, and very simple, definition is: Data which is regularly organized in three orthogonal directions and thus suitable for interpretation with a 3-D software package on an interactive workstation. This is, of course, very broad and thus admits a wide spectrum of possibilities. It says nothing about survey design, data acquisition, or data processing; it doesn't require a maximum spacing, a minimum fold, a minimum size, the definition of fringe area to ensure full migration, or any particular level of quality control in the acquisition or processing operation.

1 Abstract. The issue of climate change is a major potential impediment to effective long-range policies and management of water resources. Recently the National Aeronautics and Space Administration published a report revealing clear evidence that global climate change is occurring as this is written. This undeniable evidence of climate change must be a significant facor in water manageent since it challenges adds significant uncertainty to the reliability of past hydrologic records. This risk of uncertainty is especially disturbing for effective water sharing across jurisdictional bundaries. This article summarizes the risks to existing transboundary water sharing agreements imposed by climate change as well as identifies those agreements most at risk.


From Summary: "Such devices as leading- and trailing-edge flaps which are now in use on operational aircraft permit the attainment of maximum airplane lift coefficients, power-off, of the order of 2.8 (reference 1). Airfoil-section maximum lift coefficients as high as 5.5 have been obtained in wind-tunnel tests (see, for example, reference 2), and in a limited flight investigation airplane lift coefficients of 4.2 were obtained (reference 3)."


A special system of reaction equations describing polymer degradation is shown - using the computer algebra system Maple - to be integrable in analytic terms.


The invention relates to a method for determining the position of a measuring point of a temperature sensor for thermal error compensation of a numerical control machine, comprising the following steps of: 1. analyzing a finite element of thermal property of the numerical control machine; 2. calculating mutual information quantity of numerical control machine deformation provided by a measuring point temperature value Ti (t) according to informationism; 3. calculating mutual information quantity of numerical control machine deformation Y(t) provided by a combination of m temperature measuring points. With the method, the problem of optimized calculation for determining the position of the temperature sensor during the process of thermal error modeling for the numerical control machine can be solved. The method uses the method of numerical calculation to replace the prior experimental method, and can realize prediction of thermal deformation of the numerical control machine with the least temperature sensors, thereby effectively reducing the number of temperature measuring points of the numerical control machine, saving time and cost, and improving the validity of the thermal error compensation model of the numerical control machine.

Students at the United States Coast Guard Academy have responsibilities and stressors beyond those of traditional university students. However, no data exist to identify what type of stress students recognize in themselves, and, once assessed, what restorative techniques they use to effectively mitigate those stressors. To help understand the phenomenology of stress and its mitigation, students were asked to identify their stressors and evaluate their restorative experiences based on both the factors of the Attention Restoration Theory and psychological benefits of recreation. Results of a factor analysis of benefits related to highly restorative events provided support for the theoretical factors of Attention Restoration Theory. Suggestions to incorporate Attention Restoration Theory in U.S. Coast Guard training are provided.


FABRICATING microfluidic devices is generally a painstaking process that requires a unique mold or mask for each device configuration. Geoffrey J. T. Cooper and Leroy Cronin of the University of Glasgow, in Scotland, have now taken a step toward a more flexible approach to device fabrication by developing a way to control, in real time, the growth, direction, and diameter of self-fabricating polyoxometalate (POM) microtubes. POMs are oxo-anion clusters of early transition metals. In a previous study, Cooper, Cronin, and colleagues observed spontaneous growth of micrometer-scale tubes from a tungstate POM crystal upon immersion in an aqueous solution of a polyaromatic organic cation ( Nat. Chem. 2009, 1 , 47). The interaction of POM anions with organic cations causes a semipermeable membrane to form around the crystal, and osmotic pressure within the membrane drives microtube growth. The microtubes are uniform in diameter and sufficiently robust to allow the flow of liquid, thereby raising the possibility ...

The Arab reception of Western critical methods poses an infinite number of thorny problems, which the specialists are still unable to solve. This is applied in the human sciences field and also in other fields. The reception of the new rhetoric theory can serve as an illustrative example of this civilizational and cultural problem, because the examination of all the elements of this reception (the chronology of interaction through translation, terminology production, transfer of concepts and their integration, theorical and practical guideness) reveals the importance of the problem. In spite of this remark, the reception of the new rhetoric theory is distinguished by the concealment of some constitutive elements that have facilitated the tasks of the concerned Arab researchers, specifically the interest it gives to the rhetorical heritage. The problems mentioned are: Arab equivalents / plethora and dispersion, lexical dependence of the source language, neglectof the socio-cultural dimension, neglect of the textual approach in the translation of terms. These problems are referred to in this article, in three forms of reception: the presentation of the theory, the theoretical recall, and the conceptual support inthe practical studies.


High activity TiCl4/MgCl2/ethyl benzoate (EB)/triethyl aluminum (TEA) catalysts for the polymerization of propylene were synthesized and characterized for particle size distribution and crystallinity. Polymerization was carried out in a semibatch, constant pressure slurry reactor. A correction for interfacial mass transfer was found to be necessary to relate the monomer feed rate to the instantaneous rate of polymerization. Without such a correction serious misinterpretation of rate data could result. Optimum productivity was observed with respect to the Al/Ti ratio. Similar behavior was observed with polymerization temperature. Isotacticity increased with polymerization tamperature and decreased with Al/Ti ratio. The addition of a small amount of 2,2,6,6-tetramethylpiperidine increased the percentage of isotactic polypropylene to 98% without significantly affecting productivity.


An extremely simple method for building a basic loudspeaker is presented. This loudspeaker may be built in just a few minutes from a bare minimum of materials.


Protein fractions obtained by filtration of crude extracts of roots from the sacculinid parasite Loxothylacus panopei were tested by repeated injections on healthy male crabs Rhithropanopeus harrisii, the usual host of the rhizocephalan. Testes, and rogenic glands and different parts of the host CNS were observed; the behaviour of the animals was also noted. For the first time, proteinaceous substance(s) of about 25000–30000 daltons were characterized. They induce inhibition of spermatogenesis, and rogenic gland cytolysis and depletion of the sinus gland as in naturally infested crabs. The mode of action of sacculinid on spermatogenesis in the host is discussed.


Currently, the Colombian pension system is facing a serious crisis associated with various factors, among which are the sustainability of the system, population aging, low coverage rates, and others. Nevertheless, it is possible to point out that this crisis dates back to the origins of the system, where the lack of foresight in the adoption of a sustainable model and the structural failures of the system generated, over time, difficulties that threaten its existence. Given this situation, initiatives that aim to cope with this crisis have emerged from different political and economic sectors and organizations. However, these proposals imply serious reforms to the current scheme and face some legal limitations. Therefore, the present paper analyses, through a documental tracking, the reform proposals to the general pension system that different international economic organizations have formulated for Colombia, their effects and implications based on the main issues underlying the system. All of this in order to highlight the need to accomplish legislative adjustments that allow for a structural reform of the pension system. To that end, proposals made by different organizations that best adapt to the challenges of the Colombian pension system are acknowledged.


The purpose of this study were to determine the minimum embedment depths required for commercially available 3/4-inch-diameter polyester resin capsule anchor systems to withstand direct tensile desing loads of 6300 and 3150 pounds with acceptable short-term creep over a 100-hour time period. Short-term creep behavior was determined for thirty-six 3/4-inch-diameter resin capsule anchors and is presented and discussed. Four series of tests were conducted. Nine threaded rods in each of the first and third test series were installed in 5-inch-deep holes at 4 3/8 and 2 3/4-inch edge distances, respectively. Creep was monitored while the rods were subjected to a 9450-pound sustained axial tensile test load. In the second and fourth test series, nine threaded rods in each test series were installed in 4-inch-deep holes at 4 3/8 and 2 3/4-inch edge distances. Creep was monitored while the rods were subjected to a 4725-pound sustained axial tensile test load. It was determined that for the 3/4-inch-diameter ASTM A-307 threaded rods installed with resin capsule anchors and under conditions tested, allowable tensile design loads of 6300 pounds for rods embedded four inches are acceptable. Short-term creep values for all systems tested were suustantially lower than the maximum permitted. All three brands of resin capsule anchors that were tested performed satisfactorily. (Author)


In The Corporative Strategy Field, several works from 1990 and 2000 year study how the strategies should be formulated to guarantee the success of the corporations. But just a few authors write about obstacles or models to enhance the strategy implementation. Based on how important the middle management is over an organizational strategy implementation, this study has the objective of identifying what motivates and influences the middle managers to understand the company strategies. By interviewing the middle managers from a big national bank, this study presents an investigation about similarities and differences from what the interviewed managers think versus what the strategy theory states. Considering the studies of Hornsby (2002), Okumus (2001), Noble (1999), Littler (2000), it was possible to verify that middle managers' opinion is compatible with actual literature of the models and barriers to implement strategies subject. The main relevant factors that are critical in the strategy implementation in the view of the big national bank middle managers are: transactional, frequent and decentralized communication, the strong involvement of high management over implementation process, development of a broader and qualitative approach in the strategy implementation processes, organizational culture favorable to changes, risks and errors tolerance and clear definition of what every member of the team will earn.


Maculodistrophy (involutionary central chorioretinal degeneration, ICCRD) is the main cause of poor sight and blindness in persons over 65 years old, with a stable tendency to «rejuvenation». For its treatment and prevention, it is insistently recommended to use preparations containing bilberry, although there are extremely few proofs of their efficacy. Previously, we demonstrated the capacity of 25bilberry extract enriched with selenium (myrtasol, produced by «Sibbiotech») to prevent maculodistrophy in rats with precocious aging (rat strain OXYS). For estimation of therapeutic potentials of the drug, a clinical study comparison of efficiency of ICCRD in the treatment of maculodistrophy with myrtasol and traditional treatment (0,5 ml of 1% emoxypine under the conjunctive plus 2.0 ml of caviton interavenously) was carried out. Myrtasol administration (15 drops twice a day) for 90 days increased the patients, sight, having improved the fundus images the electrophysiological indicators of the functional state of internal layers of retina, and decreased the frequency of hemorrhages, solid exsudates (druses), ischaemic foci, newly formed blood vessels, signs of detached retina of pigment and neuroepithelium. The traditional treatment was low effective.


A slide closure for a vessel containing molten metal, including a slide housing 11 and the slide unit 12 is capable of movement in the longitudinal direction toward the slide housing, and at least one of the inside of the slide housing and slide unit the closing plate (13, 14) for fire-resistant, may be inserted, respectively. The closure plate can be pressed against each other by the slide unit 12 is fixed to the slide housing (11). The closing plate (13, 14) can be fixed and centered in the slide unit by the positioning unit 30 with a movable positioning element (33), respectively. The slide unit 12 wherein the positioning element (33) is arranged as before, therefore, each of the closure plates (13, 14) inside the sliding unit and the housing for the slide to be fixed to the slide housing 11 is the placement device 30 is designed such that each of the clamping and centering. Therefore in spite of easy operation and ensure that the operation is increased reliability, since the closing plates are fixed and centered mechanically.


This paper examined whether angling catch behaviors, angler characteristics, and angler evaluations could explain the decisions by anglers to harvest caught fish. Particularly, we determined if the propensity of tourist anglers to harvest caught walleye ( Stizostedion vitreum ), northern pike ( Esox lucius ), and smallmouth bass ( Micropterus Dolomieui ) was related to variables that measured catch rates, angling effort, catch rates for substitute fish species, motivational item importance, and/or social group variables. The results showed that catch rates and angling effort were essential for explaining anglers' decisions to harvest caught fish. Although explaining much less of the variation in the harvest behavior among anglers, the results also showed that standard concepts of human dimensions research such as substitution, motivation, and social groups were statistically related to the decisions of harvesting caught fish by anglers.


Lowland rice production is highly vulnerable to extreme temperature as a result of climate change. The study analyses farmer's perception about climate change, management practice and their on-farm adoption strategies at the rice fields of Sapu and Kuntaur study location. The selected villages were the main rice production area, where rice is a monoculture crop. Focus group discussion was held with twenty rice growing farmers at Sapuand Kuntaur, and these were divided into five groups. Personal interview and key informant involves the two village head, two youth development chairpersons (VDC) and the extension worker overseeing both villages. This was done to gain in-depth knowledge on the subject matter. The analysis results indicated that more than 50% of the rice growing farmers were female and do not undergo formal education. More than 70% of them having perceived knowledge on the causes of climate change, inorganic fertilizer use, transplanting of rice seedlings, use of improved rice varieties, and on-farm coping strategies such as changing of cropping calendar and the use of pesticides to cope with current and future climate situation.


Balanced Fertilization and nutrient cycling test were carried out in Huzhu County Caijiaying Baoxiang study the impact of different fertilization on plateau arid mountain potato field production,on plant samples nitrogen absorption,distribution and soil leaching solution of nitrate and ammonium nitrogen content.The results showed that the ordinary application of slow release nitrogen fertilizer and nutrients such as nitrogen fertilizer compared,the increase was 10.6%,17.4%;With the advance of potato growing period,the nitrogen content in potato organs gradually declining trend,which leaves decrease of the nitrogen content in the vegetative growth stage,the reproductive growth stage 80 days of slow release nitrogen fertilizer than ordinary urea and 50 days of slow release nitrogen fertilizer is more conducive to stem the transfer of nitrogen to the potato leaves and yield organs,50 days slow release nitrogen fertilizer nitrogen accumulation in the enlargement period than other treatments,including CK,OPT is 88% higher,68%,almost the same potato demand for nitrogen and slow release 50d nitrogen fertilizer release law.Other organs downward trend of relatively flat growth period can delay the rate of conversion of nitrogen to nitrate,longer time to plant nitrogen nutrient to improve potato production.Soil and nitrogen fertilizer was applied to a variety of forms,but the downward leaching nitrogen compounds always in nitrate-based,while the trend in nitrate leaching nitrate content decreased gradually as the depth increases.


Since 1969 the world's first Open University has been set up in the UK,the open education teaching mode has been widely promoted in the world.Building the modern Open University which is accommodate the development of the times in China,it can not only meet the practical needs of the system of lifelong education,but also it can create a learning society,and promote the socialist modernization objective.At present,in the process of building the Open University,we should be clearly the meaning of Open University,the development goals,school autonomy,and several other strategic issues,and make a good planning and design.


Seasonal variations in the content of the dissolved (DOC) and particulate (POC) fractions of organic carbon were investigated in the waters of lakes Œwiête and £añskie. The SUVA260 parameter, which is the value of absorbance normalized against DOC, was used in the qualitative description of dissolved organic matter. The results of the investigations indicated that the concentration of organic carbon was higher in Lake Œwiête, which is evidence that this basin is more productive. High concentrations of DOC in summer accompanied by low SUVA260 values indicate that the main source of organic matter in this basin is primary production. This is confirmed by the high chlorophyll content, low visibility, and oxygen over-saturation in the surface water layer. In accordance with the criteria proposed by Thurman (1985), while both of the studied lakes are mesotrophic, the range of DOC concentration in Lake Œwiête indicates that the eutrophication process there is more advanced.


The paper gives the definition of container productive quantity and its influencing factors and outlines the three-step procedure for its forecasting: first,using the moving average method to trim the historical data and Brown non-linear expotential smoothing method to forecast the total volume of foreign trade;second,calculating the various coefficients of the quantity of containers generated according to data such as value and weight of containerized goods,etc;third,using the multi-factor dynamic coefficient generating method to forecasting the productive quantity of the containers generated.


The Small Magellanic Cloud (SMC) is the second-largest satellite galaxy of the Milky Way and is only 60 kpc away. As a nearby, massive, and dense object with relatively low astrophysical backgrounds, it is a natural target for dark matter indirect detection searches. In this work, we use six years of Pass 8 data from the Fermi Large Area Telescope to search for gamma-ray signals of dark matter annihilation in the SMC. Using data-driven fits to the gamma-ray backgrounds, and a combination of N-body simulations and direct measurements of rotation curves to estimate the SMC DM density profile, we found that the SMC was well described by standard astrophysical sources, and no signal from dark matter annihilation was detected. We set conservative upper limits on the dark matter annihilation cross section. These constraints are in agreement with stronger constraints set by searches in the Large Magellanic Cloud and approach the canonical thermal relic cross section at dark matter masses lower than 10 GeV in the $b\bar{b}$ and $\tau^+\tau^-$ channels.


The article what the author has learned from her many years' physics teaching pratice. It expounds that a teacher can teach physics course well only under the guidence of the dialectical materialism point of view and methods and that students can study it well only according to the laws of the dialectical materialism.
The opinions mentioned in this paper does reflect the authors styles in everyday study, life and work. As she pays attention to permeating the moral edulation into the physics teaching and is an observant and conscientious person in teaching, so the auther has gotten gratifying result in training successors.


A FOLLOW-UP of servicemen who had sustained head injuries during or shortly after the Korean campaign provided the opportunity to reconsider the significance of epileptic seizures that occurred during the early stage of wound healing.'-5 These servicemen have formed the basis of a previous report in which the incidence of epilepsy occurring more than one month after injury was analyzed.5 The composition of the series has been described in that report.


Writing about many of those material and textual things that constitute what we call modernism and postmodernism through means provided by contemporary, mainstream academic art history and theory drags them back into those very explanatory, realistic, and representational forms repudiated by twentieth-century avant-gardes. One challenge for trained writers on art concerned with such material is to adapt their writing to forms of utterance that (post)modernist art and writing deploys in its refusal to inherit traditional, certaintist rhetorical codes. Middle voice offers one means of rethinking agency in art writing along such lines. Its writer-observers neither grasp nor are grasped by phenomena, but are changed by articulating them whilst observing and recording something of this change. Such an unorthodox configuration of relations between perceiver and phenomena means that middle voice is difficult to conceive within limits of realism dictated by academic art writing. Consequently, one of these texts argues for a greater diversity in art writing; the other is a performance of this writing, meant to shadow, mimic, and play off (without describing, delimiting, or determining) a work of art.

ForThakur, Canadian policy was certainly anti-communist in its approach, such anti-communism being partly indigenous and partly derivative from "the American factor" in Canadian thinking. But unlike Eayrs, or Charles Taylor (Snow Job: Canada, the United States and Vietnam 1954-1973 [Toronto: Anansi, 1974]), whom he explicitly castigates for "incomplete, erroneous and harsh" judgments of Canadian policy (206), Thakurfinds no fault with Ottawa on this count. "The Commission's reports show Canada to have jointly striven towards an effective peacekeeping role in the first one or two years. From this it follows that the Canadians in the beginning pursued a policy opposed to American desires" (206-07). Furthermore, Canadian policy in the 1960s does not deserve harsh criticism either, he asserts, because "ultimately there was little that the Canadians could have done to temper American excesses or diminish the warfare; to claim otherwise would be pretentious" (207). This study is not without problems. The analysis of the legal implications of the Geneva Agreements is uncertain and at various points contradictory. The alleged motivations behind particular policies are too frequently inferred from broader foreign policy orientations in a rather mechanistic fashion that obscures the inner tensions of each government's decision-making process. Justifications for Indian policy are at times accepted uncritically. But on the whole Peacekeeping in Vietnam should prove to be quite a constructive contribution to Canada's Vietnam debate.


pointing. Alan Whitehorn and Keith Archer's study of the federal New Democratic party, for example, while a thorough survey of the participation of women at the various levels of the party hierarchy, fails to provide the context that would make the quantitative analysis of attitudinal differences between male and female party activists more meaningful. Francois-Pierre Gingras' content analysis of three Ottawa-area daily newspapers is similarly unsatisfying: a quantitative study of positive, negative and neutral media references to women is of limited use in the absence of much other information. Dividing the media references into general subject categories which oppose the political and the social, Gingras recognizes but does not engage with the feminist challenge to an understanding of political life based on these exclusive categories. In contrast, two articles that focus on the ambivalent relationship between feminism and nationalism in Quebec, by Roberta Hamilton and Micheline Dumont, are particularly attentive to social and historical context. These articles will be particularly rewarding for readers unaware of the differences in the relationships between feminists and government in English Canada and in Quebec. Overall, the volume's most valuable contribution is the insightful, gender-sensitive analysis of public policy in Canada that it offers. The section on the portrayal of gender in the media, however, lacks the depth and coherence of the rest of the collection. The second article by Gingras in this section, a study of attitudes towards peacekeeping of male and female Catholics in the military, seems peculiarly out of place here, suggesting that Gingras might have used his editor's privilege with more discretion in this case.


ABSTRACT Green tea catechins can improve human health, and their retention during processing is a concern. High hydrostatic pressure (HHP) blanching is a nonthermal processing that can increase both nutrients and flavor in tea. Thermal blanching retains catechins but decreases nutrients and flavor. We investigated catechin retention potency via HHP and thermal treatment. Fresh green tea leaves were pressurized at 100–800 MPa and/or heated for 10 min at 40°C–70°C and then stored for 24 hours. Tea catechin content was drastically reduced after storage without HHP, which yielded a 1.5–8.0-fold increase. HHP showed a smiling curve relationship with catechin retention, with the highest levels found at 200 and 800 MPa. Synergistic effects of HHP on thermal processing were found at 40°C–50°C but not at 60°C–80°C. Processing at 200 MPa combined with 50°C yielded 88% catechin retention. Our results suggest this combination as an optimal strategy for retaining tea catechins, nutrients, and flavor.


Like sculptors throughout history, from Michelangelo and Rodin to David Smith and Joseph Beuys, Antony Gormley draws. Drawing forms a major component of his creative output and he even possesses a specifically designated drawing studio. Over the years, his output has been huge and without the playful exercise of drawing there may even have been no sculpture. Yet the drawings should not be read as sketches for the sculptures but rather as part of a continuing dialogue with them. [2] According to Gormley, his work is not generic, symbolic or emblematic, but rather tries to connect the subjective and the collective in the most direct way. Given that each work "comes from a lived moment of a particular body, at a particular time, in a particular position," [3] it is not surprising that drawing forms such a central part of his practice: drawing by its very nature is the most direct indexical record of a particular body in time and space. It is the most direct form of communication between mind, eye and hand and is an intensely personal experience which offers a space for privacy and thinking.


Nonthermal atmospheric pressure plasma jet (APPJ) is a promising method for medical applications. In particular, it can induce temporary or permanent damage to tissue known as reversible electroporation (RE) and irreversible electroporation (IRE), respectively. RE enables the transfer of genes, drugs and proteins into cells. APPJ generates reactive oxygen and nitrogen species (RONS), which induces oxidative and nitrosative stress to cells. By generating low level of RONS, APPJ may change the sensitization of cells to RE and facilitate plasmid DNA delivery to cells and tissue. In this paper, we report pilot studies where air or helium plasma jets were applied to Guinea pigs for plasmid DNA delivery in vivo. Both devices were based on a dielectric barrier discharge (DBD) configuration. The air plasma jet was powered by a compact DC power supply, while the He plasma jet was driven by 200 ns, 8 kV pulses at 1 kHz. Plasmid encoding luciferase was delivered with each device. Bioluminescence was measured using an IVIS in vivo imager to evaluate expression levels achieved using the different delivery methods including plasma alone and the combination with pulsed electric fields (electroporation). The power consumptions were determined based on voltage and current measurements. RONS production by different plasma jets were evaluated.


PhyA from Selenomonas ruminantium (PhyAsr), is a bacterial protein tyrosine phosphatase (PTP)‐like inositol polyphosphate phosphatase (IPPase) that is distantly related to known PTPs. PhyAsr has a second substrate binding site referred to as a standby site and the P‐loop (HCX5R) has been observed in both open (inactive) and closed (active) conformations. Site‐directed mutagenesis and kinetic and structural studies indicate PhyAsr follows a classical PTP mechanism of hydrolysis and has a broad specificity toward polyphosphorylated myo‐inositol substrates, including phosphoinositides. Kinetic and molecular docking experiments demonstrate PhyAsr preferentially cleaves the 3‐phosphate position of Ins P6 and will produce Ins(2)P via a highly ordered series of sequential dephosphorylations: D‐Ins(1,2,4,5,6)P5, Ins(2,4,5,6)P4, D‐Ins(2,4,5)P3, and D‐Ins(2,4)P2. The data support a distributive enzyme mechanism and suggest the PhyAsr standby site is involved in the recruitment of substrate. Structural studies at physiological pH and high salt concentrations demonstrate the "closed" or active P‐loop conformation can be induced in the absence of substrate. These results suggest PhyAsr should be reclassified as a D‐3 myo‐inositol hexakisphosphate phosphohydrolase and suggest the PhyAsr reaction mechanism is more similar to that of PTPs than previously suspected.


The study examined the minority group-threat hypothesis across a metropolitan setting to test whether (1) increases in black and Latino representation in communities were associated with increased misdemeanor arrests and (2) if increases in minority groups in historically white communities were associated with increased police arrests. The study argued that threat trigger variables should be measured in terms of difference scores and weighted by initial dominant group representation. The latter argument is informed by the defended neighborhood perspective and assesses the threat hypotheses in historically white communities. Using negative binomial regression modeling that adjusted for spatial autocorrelation, the study found that net of theoretical controls, increases in percent black population were associated with increased black misdemeanor arrests, but only in historically white census tracts. Increases in Latino representation were associated with increased minority misdemeanor arrests both across all tracts generally, as well as in historically majority white tracts.


ing wall that seems to block China's national aspirations in the present." By implications, Ojha reduces imperialism to a negative impediment-a towering wall that blocks China's desire for the status of super power, i.e., the potential Chinese imperialism. One does not fight with the conclusions of ojha so long he stich.; to hi.; guns in a consistent manner. But if imperialism is not dead, if i t is more than a scapegoat for part hurnili:ttioiis, i t is not enough to define i t only in terms of blocking China's national akpirations: its various ramifications have to be traced and brought into focus in order to appreciate the anti-imperialist obsession of Radio Peking. With Ojha, Taiwan is the large\t tree i n thc forest. In scarch of trees, large and small, Ojha misses the fore\t. Probably, the forest is of no consequence in his scheme of things. The problem of assessing the foreign policy of a socialid State is the problem of ascertaining the nature of the State. The ideologues of Communisni may be tempted to see in that State, which in turn reflects an ideological compromise, the zealous application of revolutionary internationalism. On the other hand, "the objective" student fails to transcend the standards of narrow frame of reference of an impericist. Ojha's merit lies in that although he belongs to the second catcgory, he is conscious of his limitations. He is, therefore, more sympathetic than many others, towards the problems and pathos of the Chinese symphony. His standards of evaluation, however inadequate they may be, are not marred by gross inequity. Few others on the field rcalisc, as he does, the moot point that while the West and the Sokiet Union have moved beyond the third generation of revolution and while Asia and Africa have not yet rcached i t . China is the most transitional society of all. and as the Third World moves forward the long-term significance of the Chinese foreign policy may offer relatibely relevant model for them. Dr. Ojha has a lucid style, analytical and succinct. It 15 a neat model, and surely, ;I welcome addition to our library on China.

The border of the shorelines in a nation is an important factor in determining the border of a national territory, but Korea's shorelines are rapidly changing due to the recent rise in sea level from global warming and growth-centered economic policy over the decades of years. This research was done centering on the areas having well-preserved shorelines as they naturally are and other areas having damaged shorelines in their vicinities due to artificial structures at the two beaches located at the neighboring areas and having mutually homogeneous ocean conditions with each other. First, this research derived the shorelines using the aerial photographies taken from 1947 until 2007 and revised the tidal levels sounding data obtained from a hydrographical survey automation system consisting of Echosounder[Echotrac 3100] and Differential Global Positioning System[Beacon]by using topographical data and ships on land obtained by applying post-processing Kinematic GPS measuring method. In addition, this research evaluated the changes and dimensional variations for the last 60 years by dividing these determined shorelines into 5 sections. As a result, the Haewundae Beach showed a total of 29% decrease rate in dimension as of the year 2007 in comparison with the year 1947 due to a rapid dimensional decline centering on its west areas, while the dimension of the Gwanganri Beach showed an increase in its dimension amounting to a total of 69% due to the decrease in flow velocity by artificial structures built on both ends of the beach-forming accumulation; thus, it was found that there existed a big difference in deposition & accumulation tendency depending on neighboring environment in spite of the homogeneous ocean conditions.


A large animal, formally described as Yorgia waggoneri (Ivantsov, in press) has been discovered at a Vendian locality on the shore of the White Sea, in northern Russia. It is anatomically transitional between the Ediacaran "segmented worms"; Dickinsonia and Spriggina. Like Dickinsonia, it had a metameric dorsal quilt, composed of a series of muscular chambers, and presumed intestinal caeca. Yorgia was unlike Dickinsonia, but similar to Spriggina, Marywadea, and Praecambridium, in that the anterior part of the dorsal quilt did not overhang the caeca. Rather, it was displaced posteriorly, with the medial chamber arched to the left. In effect, a lunate anterior region with ramified caeca was exposed dorsally. The left and right series of chambers were asymmetric, alternating along the mid‐line. These organisms are not related to either annelids or arthropods, but possible homologies between characters of these animals and those of present day nemerteans and some deuterostomian phyla are proposed here.

The Slovenian Karst, with its rich natural and cultural heritage, is a unique part of Slovenia that is attracting increasing numbers of real estate buyers. These would traditionally come from other parts of the country, but after Slovenia joined the European Union there has been an increase of purchases by foreign nationals. This thesis attempts to analyze real estate purchases in the Sežana administrative unit between years 2004 and 2015 based on data from the Financial Administration and the Surveying and Mapping Authority of the Republic of Slovenia. The thesis finds that the financial and economic crisis had a dampening effect on the initial surge of purchases but interest has built up again in recent years, especially after 2015. The driving force behind the increase are Italian nationals who benefit from the location along the Italian border. As part of this thesis, a survey was conducted among locals who shared their views on the growing number of foreign property owners and how these individuals adapt and integrate. Also, structured interviews were carried out among foreign property owners, investigating the factors that influenced their buying decisions and their views on integrating into the Slovenian environment and society. The thesis found that foreign nationals tend to buy older Karst houses to use as primary residence and renovate them in traditional Karst style. The price plays the biggest role in buying decisions, followed by favorable climate, intact nature and a quiet way of life. Italian buyers also value the proximity to their jobs and homes in Italy. Locals generally accept foreign property owners, yet they do not want their numbers to grow uncontrollably and prevail over the local population, which is why they want laws to regulate foreign buyers. However, the state and municipal authorities are to blame for devastation of karst landscape with extensive and improper building in order to sell to foreign nationals, because they are not able to agree how to protect Karst and its architecture.


The gain dynamics of a symmetrical multiple-quantum-well semiconductor optical amplifier (SOA) with wide gain-bandwidth are measured by a two-color heterodyne pump-probe technique. Short optical pulses are generated by using optical filters to select spectral components from compressed supercontinuum optical pulses. To maintain durations of the order of 100 fs over the entire gain bandwidth of the SOA, the pulse broadening caused by frequency shifters is compensated by fibers with lengths optimized for respective wavelengths. We measure the wavelength dependences of the recovery time of carrier heating (CH) and the gain reduction due to CH. The gain reduction caused by spectral hole burning is observed.
