Evolution of a space charge with time of electric field application is investigated in cross-linked polyethylene (XLPE) and ethylene propylene rubber (EPR) subjected to uniform AC and DC fields of /spl sim/60 kV/mm. To simulate the insulation of polymeric high voltage cables the specimens were equipped with semicon electrodes. In order to minimize the effect of the amount of space charge variation between various specimens of the same material prior to aging, single specimens were subjected to a repetitive series of voltage aging for a predetermined period of time and space charge distribution measurements. The Thermal Step Method was used to measure the space charge distribution. During DC aging EPR insulation accumulates significantly more space charge than XLPE. Heterocharges are formed in EPR and homocharges in XLPE. Local electric fields created in the insulation by the accumulated space charge can be significant. AC aging generates comparable amount of space charge in both materials, which is significantly less than the amount of charge measured after DC aging.


The real-time remote communication of UAVs beyond the visual range is the key to breaking through the mission constraints of UAVs and improving the implementation efficiency of UAVs. It is also a powerful way to expand the application capabilities of UAVs in the industry. By combining UAV technology with modern 4/5G communication network technology, key technologies such as multi-base station relay, antenna optimization, and PTZ measurement and control are adopted to ensure the real-time and remote interaction needs of world-ground information. Through the process of indoor desktop test to field test, a set of mobile communication network design methods suitable for UAV mid-to-low-altitude flight are explored. The innovative way of combining mobile communication technology and drone cruise technology can provide users with a newer, faster, and more efficient way to achieve cruise needs. It is an important link in the formation of a large air-space-earth Internet of Things network. It is in the field of drones. A new breakthrough in communication.


in response to a desire to expose our collections to a broader audience. We knew, as every archives staff knows, that we held innumerable treasures in our collections that were not fully appreciated by our audience. Simultaneously, we felt that our univer-sity's student body was underexposed to primary research in a professional archive, and we looked for an opportunity to bring more students into active engagement with the materials. A digital project that involved undergraduate students would potentially accomplish both of these goals: students would personally work with collections and learn more about the benefits of archival research through use of the materials in potentially compelling interpretative projects, and the online world would be able to discover our collections digitally. Nebraska U: A Collaborative History (http://unlhis-tory.unl.edu) is an effort to help prioritize, digitize, and contextualize materials held within the University Archives in the UNL Libraries. The site is currently imagined as a combination of an access point for digitized University history materials (mul-timedia and texts) and a series ofstudent-driven research projects with focused presentations on select subjects, which build upon and link to transcribed texts, scanned images, and other digital derivatives of archival material. Such a site is a unique resource for the many researchers, scholars, and members of the public interested in the history of the University of Nebraska, and it provides excellent visibility for materials in the Archives. An important part aspect of the project's deSign is the way it serves as outreach to the campus and, specifically, its use as a pedagogical tool. Kenneth Price, Professor of English, and his students were the first collaborators on the project in his fall200S class "Electronic Texts: Theory and Practice." As part of the course, students selected a topic from several suggested to them, did research in the Archives , selected materials for digitization, scanned images and/or encoded texts, and wrote essays con-textualizing their material. In the years since this initial collaboration, many students have continued to contribute to the site, both via classrooms and the University's Undergraduate Creative Activities and Research Experiences (UCARE) program.I The most significant collaboration in the past few years has been with Douglas Seefeldt's "Digital His-tory" course. Undergraduate students in that course were aSSigned a Nebraska U project, which means they had to select a topic relevant to the history of the University of Nebraska, research that topic in the Archives, prepare or obtain digital …

The present invention relates to a cosmetic container having an airtight refill case, for containing, in an inner refill case, cosmetics such as moisture compact powder, moisture cream and eye-shadow, in an airtight manner. More specifically, the cosmetic container according to the present invention is capable of ensuring better airtightness of a refill case (20), by connecting an upper lid (25) and a lower main body (21) of the refill case (20) using a butterfly hinge, by performing double airtight coupling using an assembly groove (22) having a ring-shaped assembly protrusion (23) and an assembly protrusion (26) having a ring-shaped assembly groove (27) without using any separate packing, and by performing airtight coupling by pressurizing the upper lid using a pressurizing protrusion (30) of the upper lid of the refill case during the closing-operation of an outer container lid. Accordingly, the present invention prevents outside air from flowing into the refill case and prevents evaporation of internal moisture and volatile components so that it is possible to use cosmetics while maintaining the quality thereof for a long time without deterioration.


ABSTRACT This paper attempts to converge the utilitarian or provider-based concept of service quality and the experiential or customer-based concept of satisfaction. It presents two empirical projects which examined visitor's service quality and satisfaction judgements by alternative methodological approaches. The first is a quantitative study of visitor's assessment of historic houses, illustrating that quality and satisfaction concepts can be successfully combined into a model of the means-end chain type. The second is a qualitative study of visitor's narrative assessment of successive service experiences, highlighting the various functions of service quality aspects during the entire holiday stay. Finally, the authors argue that these kinds of approaches may contribute to the academic debate on satisfaction and service quality constructs, and will equally open up new opportunities for service and destination marketers in tourism.


ABSTRACT We present the results of an empirical study of a sample made up of 392 students newly admitted to the architecture, design and urban planning courses run by the University of Buenos Aires, Argentina. Our purpose is to explore the recognition and construction skills applied in geometric representation tasks, in order to assess possible differences between: (i) recognition and construction tasks; and (ii) tasks involving matching views to volume on the one hand and three-dimensional to two dimensional representations on the other. Our findings indicate that construction is harder than recognition, and, as far as the former is concerned, the path from orthogonal to axonometric representation is more difficult than the reverse. Gender and type of secondary schooling are significantly related to performance, with higher scores for male subjects and graduates from technologically oriented secondary schools than for female participants and graduates from non-technological schools respectively.


1Results do not change when controlling for demographics. See Figure S1 in Supplementary Material. 2Unfortunately, we cannot test this explanation directly. Negative D-scores could of course be the result of strong mental associations between the Republican Party and blacks (rather than whites) while not having a strong schema about the Democratic Party. Substantively, that would be "negative projection," or imposing the racial outgroup identity onto the out-party. We suspect this explanation is less plausible, especially in the light of findings from Study 3 demonstrating that explicit schemas of the Republican Party as white are uniform in the sample. 3We worried that respondents, especially whites, might underreport the association of the Democratic Party with blacks due to social desirability concerns. If so, the variation of schemas in the population would be underestimated, with more respondents reporting that both parties were white. Underestimating this variance, in turn, would lead to smaller and less significant associations between schemas and other variables of interest. This suggests that our test is a conservative one. 3This change in partisan affect informed by race–party schemas can ultimately lead to sorting. The possibility of white Americans defecting from the Democrats in response to its increasing racial liberalism and the growing share of nonwhites in the party has been shown in the literature before (Hajnal and Rivera 2014; Valentino and Sears 2005; Zingher 2018). Our findings suggest that this process may continue in the foreseeable future.


A dynamic windproof safety device of an on-track crane comprises a locating component, a guide component, a long steel rod component, a triggering component and a control unit, wherein the locating component is connected on the side surface of a crane trolley, or below a lower cross beam or simultaneously fixed on the crane trolley and the lower cross beam; the guide component is connected below the lower cross beam; the triggering component is arranged on the guide component; the control unit is electrically connected with the triggering component; the long steel rod component comprises a steel rod and a fixed steel plate that is fixed at one end of the steel rod; the locating component is provided with a locating hole for locating a long steel rod; the guide component is provided with a guide slot for guiding the long steel rod; the fixed steel plate can not pass through the locating hole; and the long steel rod is arranged right above the track of the crane. A crane in assisting working condition conducts braking for wind prevention, therefore, the safety device overcomes the defect that the traditional windproof device can not stop the crane and possibly overturn the crane when the braking force is insufficient under a gust of sudden wind, and improves the reliability and safety of the crane in preventing a gust of sudden wind in working condition.


The principle and recent experimental results of optoelectronic tweezers (OET) will be presented. Based on light-induced dielectrophoresis, OET can trap and sort colloidal particles, biological cells, nanowires and nanoparticles using a digital light projector.


1. A unique breed of fowls called Ingie, found on the Tanegashima Island of Kagoshima Prefecture in Japan, is characterised by the incomplete development of the tail feathers. 2. No abnormality of the caudal skeleton was found in the Ingie fowls but the structure of anterior and posterior barbules of the tail feathers differed from those of the normal fowl. 3. Genetical analysis indicated that the hypoplasia of the tail feathers is inherited as an autosomal dominant character: the symbol Hy is proposed for the gene.


The constitution of automotive CO2 air-conditioner and its working principle are introduced here. The characteristics of the main parts in refrigerating system and technical key points are analyzed.


Theoretical importance and practical implications of research on computer speech recognition generate considerable interest in this field among linguists, psychologists, and communication engineers alike. The long-term aim is to design a model reflecting the speech perception process and eventually simulate it by a computer program able to perform speaker-independent speech recognition. The present study focuses on one aspect relevant for tone languages, the recognition of lexical tones. The language chosen is Mandarin Chinese (MC). To build the tone-perception model, two aspects of tone were investigated: perceptual dimensions and domain. The perceptual dimensions specify which acoustic cues contribute to the lexical tone perception and how these cues are represented in the auditory system. Tone domain determines where in the syllable the lexical tone is physically located


Carbon-based thin films deposited on surfaces exposed to a typical capacitively-coupled RF plasma are sources of molecular precursors at the origin of nanoparticle growth. This growth leads to drastic changes of the plasma characteristics. Thus, a precise understanding of the dusty plasma structure and dynamics is required to control the plasma evolution and the nanoparticle growth. Optical diagnostics can reveal some particular features occurring in these kinds of plasmas. High-speed imaging of the plasma glow shows that instabilities induced by nanoparticle growth can be constituted of small brighter plasma regions (plasmoids) that rotate around the electrodes. A single bigger region of enhanced emission is also of particular interest: the void, a main central dust-free region, has very distinct plasma properties than the surrounding dusty region. This particularity is emphasized using optical emission spectroscopy with spatiotemporal resolution. Emission profiles are obtained for the buffer gas and the carbonaceous molecules giving insights on the changes of the electron energy distribution function during dust particle growth. Dense clouds of nanoparticles are shown to be easily formed from two different thin films, one constituted of polymer and the other one created by the plasma decomposition of ethanol.


A microwave absorber constructed by an array of the folded dipole with resistive loads and backed by a ground plane with distance from λ/8 to λ/4 are investigated. The admittance of a folded dipole shows that it is actually a two-port filter which is adjustable by changing the radii and the separation between the two lines of the folded dipole, and therefore can improve the bandwidth of unfolded dipole absorber. Comparing to the absorber with unfolded dipole array, the bandwidth can be broadened by 200% with unequal radii of two lines, and the thickness can be decreased by 25%. The operating frequency of the improved dipole absorber is f0 = 10 GHz and is constructed on substrate with dielectric constant 2.65.


Background: Since 1990, more than 60 chemical accidents with more than 2,000 victims have been recorded based on the cases of poisoninings reported by physicians in Germany. Experience from and analysis of these accidents has shown that in addition to a systematic documentation and analysis, the activities in major industrial accidents involving chemicals should be coordinated and structured from the very beginning


Spherically symmetric Kantowski-Sachs space-time is studied in Rosen's (1973) bimetric theory of gravitation, considering the source of gravitation as perfect fluid and scalar meson field. It is shown that a macro cosmological model – represented by perfect fluid distribution – does not exist, and only a vacuum model can be constructed, whereas in case of a micro cosmological model represented by a scalar meson field exists, and the model is obtained as in the case of Mohanty & Sahoo (2002).


To solve the control problem of large-scale spacecraft clustering flying,this paper proposes a formation reconfiguration control method based on improved artificial potential filed and sliding mode control technique.The nonlinear equation of relative motion dynamics was adopted,the enhanced artificial potential method was proposed to avoid collisions among the spacecraft,and the sliding mode variable structure control method was established for precise formation control in the presence of model and perturbations uncertainties.The global asymptotic stability was proved using Lyapunov stability theory.The numerical simulation results verify the effectiveness and feasibility of the proposed controller.


This research aims to provide empirical evidence regarding the factors that influence the timeliness of submitting interim financial reports to companies listed on the Indonesia Stock Exchange. The population used in this research is companies that received sanctions in the form of written warnings in the second quarter of 2022 by the Indonesian Stock Exchange. The approach used is a qualitative approach with logistic regression analysis as a data analysis method because this method is suitable for research that has a dependent variable that is measured by a dummy variable. Determining the research sample used the purposive sampling method which resulted in a sample of 162 companies. This research provides evidence that financial distress has a negative and significant influence on the timeliness of submitting interim financial reports, while profitability and leverage do not affect the company's timeliness in submitting its interim financial reports.


The paper presents methodologies associated with vi sualization, which supports data analysis. Analyzed data has been gathered by H oneyPot systems deployed in the network of Institute of Computer Science. Due t o the vast amounts of data, the manual analysis was almost impossible and very impr actical, also considering time constraints. Introduced visualization techniques an d supporting filtering features are implemented in HPMS (HoneyPot Management System). T he paper describes in details two introduced methodologies which support data analysis using both charts and graphs. The first one is used for the discovery of basic activities observed by HoneyPot. The second one is used for advanced analy sis of machines used during attacks concerning PhpMyAdmin software.


Kernel function is the function which computes dot product in feature spaces. Both the SVMs and kernel PCA are kernel.based learning methods. In this paper, the SVMs and kernel PCA are used to tackle the face recognition problem. SVMs are classifiers which have demonstrated high generalization capabilities. Kernel PCA is a feature extraction technique which is proposed as a nonlinear extension of a PCA. We illustrate the potential of SVMs and kernel PCA on the Yale database and compare with a PCA based algorithm. The experiments indicate that SVMs and kernel PCA are superior to the PCA method.


Presbyterians were pioneers in the settling of Kentucky. They came early, put down deep roots and prospered. Soon they were one of the most influential groups in the state. For a number of reasons—including perhaps the relative lack of emotionalism in their services, their insistence on an educated clergy and their frequent schisms—their numbers remained small and during the 19th century became a decreasing percentage of Kentucky's population. Other factors also contributed to the low numbers of Kentucky Presbyterians: the greater success of Baptists and Methodists (and later, the Christians or Campbellites) at winning converts and the increasing migrations to Kentucky during the mid-19th century from Catholic countries of Europe. Following the Civil War, however, Presbyterians made giant efforts to "Presbyterianize" Kentucky. The task, indeed, was gargantuan. In 1877 Dr. Edward O. Guerrant, a prominent Kentucky minister, reported to the synod meeting in Covington that of 100 counties in the state (at that time), 60 were without a single Presbyterian church. He further revealed that of the more than one million people in Kentucky, scarcely 10,000 were Presbyterians. Guerrant pictured the sad state of the entire church in Kentucky in these graphic words: "In one day's ride from Mt. Sterling, the capital of eastern Kentucky, there are four county seats which have no houses of worship, and some of these towns contain hundreds of souls. They have jails and gambling halls, but no house for God's worship.. . . In spite of the fact of great increase of population, wealth, general intelligence, morality and facilities for travel and commerce, the Church has stood still, or gone at

To tackle the problem of partial loss of image details in infrared and visible image fusion, a gradient transfer optimization model is proposed for the fusion of infrared and visible images. Firstly, an adaptive image decomposition method is proposed based on coupled partial differential equation, the infrared image and the visible image are decomposed into base layer and detail layer to extract the high-brightness target and the details of the two images. Based on this superior information of infrared image and visible image, the optimization model is designed to obtain the fusion image obvious target and rich details. For the proposed optimization model, Alternating Direction Method of Multipliers (ADMM) is used to decompose the original model into sub-problems that are easy to solve and iteratively optimize to obtain the optimal solution. The introduction of control parameters makes the model more flexible in different situations, and retains the thermal radiation information of the infrared image and the detailed information of the visible image to the greatest extent. The fused image visual effects and performance indicators are improved. We completed the experiment using a public data set and analyzed the experimental results. The experimental results show that the proposed method can better preserve the clear target and texture information of infrared and visible images, and the fusion results are more accurate and comprehensive. The experiment results also indicate that our method performs well and achieves comparable metric values with the state-of-the-art methods.


The invention discloses a method for controlling effective protection of a server through current detection. The purposes that the downtime is shortened while the server is protected are achieved by detecting the current magnitude by a control chip through current information fed back by an MOS, comparing the current magnitude with a set slow OCP value and fast OCP value and controlling the switching state of the MOS. According to the method, the implementing mode is simple, the control chip achieves control over the switching state of the MOS according to current feedback of the MOS only by enabling a power supply of the server to form a power supply system of a board card through the control chip and the MOS, and meanwhile the switching state of the MOS is transmitted to a data collecting unit through a PMBUS to be monitored in real time. Compared with an original server protection mode, the server downtime can be greatly shortened and important data can be prevented from being lost while devices and the board card are protected, transient overcurrent brought by interference or overload work in a short time can be avoided, and meanwhile currents detected by an MOS Rdson are more precise.


It is well known since the Apollo missions that the lunar surface is covered with a thick layer of micron size dust grains with unusually high adhesive characteristics. The dust grains levitated and transported on the lunar surface are believed to have a hazardous impact on the robotic and human missions to the Moon. The observed dust phenomena are attributed to the lunar dust being charged positively during the day by UV photoelectric emissions, and negatively during the night by the solar wind electrons. The current dust charging and the levitation models, however, do not fully explain the observed phenomena, with the uncertainty of dust charging processes and the equilibrium potentials of the individual dust grains. It is well recognized that the charging properties of individual dust grains are substantially different from those determined from measurements made on bulk materials that are currently available. An experimental facility has been developed in the Dusty Plasma Laboratory at MSFC for invest...


For a number of reasons, the aviation sector may be the most promising for expansion of the cellulosic biofuels industry (Tyner, 2012). The European Union is planning to implement a carbon tax on airplane takeoffs and landings in the EU (EU Business, 2013). Several U.S. aviation companies have expressed strong interest in renewable fuels (Midwest Aviation Sustainable Biofuels Initiative (MASBI), 2013). There are alternatives for the ground fleet that have emerged in recent years such as compressed or liquefied natural gas or electric vehicles. However, these options and ethanol are not viable in aviation. U.S. civilian aviation consumes over 21 billion gallons of jet fuel per year (U.S. Energy Information Agency Department of Energy, 2014), so it is a sizeable market. For all these reasons, evaluating the technical and economic potential of aviation biofuels has merit. We do that here by summarizing the results of a techno-economic analysis done for the fast pyrolysis process to produce drop-in hydrocarbons, including jet fuel.


The taxonomy of South-East Asian ichthyophiid caecilians is largely in a woeful state. We give a new diagnosis for Ichthyophis supachaii from Thailand, based on a reexamination of the complete type series and recently collected material. The holotype is redescribed. The higher number of splenial than dentary teeth, a previously reported main diagnostic character of the taxon, is rejected. Ichthyophis supachaii follows the usual pattern of ichthyophiid caecilians in having more dentary than splenial teeth. Nevertheless, Ichthyophis supachaii is regarded as a valid taxon based on several morphometric and meristic characters. We provide a detailed description of the male phallodeum.


What is already known about this topic? The primary causes of early miscarriage and stillbirth are chromosomal abnormalities (CAs) whose prevalence has been observed to increase in recent years. What is added by this report? According to data received from a hospital-based birth-defect surveillance system in the Haidian District, Beijing, there was a significant increase in the prevalence of CAs along with most subtypes from 2013 to 2022. This noted increase in the reported prevalence is potentially attributable to factors such as a rise in maternal age, alongside the enhanced detection efficacy resulting from the utilization of noninvasive prenatal testing. What are the implications for public health practice? The escalating prevalence of sex CAs and other previously rare CAs pose novel challenges for genetic counseling and healthcare practitioners. These professionals are tasked with the accurate evaluation and interpretation of detection data, which must then be conveyed appropriately to patients. Furthermore, it is imperative to intensify health education efforts to assist women in making informed treatment decisions, considering the diverse prognoses associated with different CAs.


Objective To learn the epidemic situation and tendency of HIV/AIDS in Yunnan province. Methods Adopting 4 serological and epidemiological methods such as sentinal surveillance, cross-sector survey, routine screening for high-risk people and voluntary anonymous test to collect epidemic data and reported cases data of HIV/AIDS in Yunnan province. Results Total of 105.587 high-risk people were surveyed in the whole province in 2003, of which there were 2 453 newly detected cases and 172 diagnosed AIDS patients and 81 deaths. The rate of HIV infection of venous drug addicts at surveillance sentinel was 21.2%(0.6%-63.0%),and the rate of venous drug addicts in 8 areas had reached a high level. The rate of HIV infection of male outpatients at venereal diseases clinics was 2.6%(0-10.8%),of which the rate of male outpatients at venereal diseases clinics in Menglian county of sima region was 10.8%; the HIV infection rate of pregnant and lying-in women was 0.4(0-1.3%), of which the rate of pregnant and lying-in women in the hospitals in Longchuan county and Yingjiang county of Dehong region was 1.3% and 1.0%; the HIV infection rate of unrelated people in hospitals of highly prevalent area was 1.3%; and that of blood donors was 0.07%, the positive rate among voluntary anonymous people was 13.1%. The infected people were mainly 20 to 30 years old male venous drug addicts of Han nationality, of which peasants and loafers took a large part, mainly distributing in Dehong, Honghe, Dali, kunming, Lincang and Baoshan of Yunnan Province. Conclusion The HIV infection of venous drug addicts prevailed with a increasing infection rate in Yunnan province, and caused HIV propagation and prevalence among sex promiscuity people. For pregnant and lying-in women, HIV infection rate had been increasing further, and the prevalence rate of unrelated people had been over 1% in the hospitals of highly prevalent areas. So the whole province was threatened by AIDS wide prevalence.


To study the effects of total solids (TS) and temperature on anaerobic digestion of fecal sludge, this study adopted a biochemical methane potential test. Feces with different TS contents (8% and 12%) were studied under mesophilic (37°C) and thermal (55°C) temperatures. This study determined total gas production, organic matter degradation rate, and gas production of digestion unit volatile solids (VS) under different conditions. In addition, the kinetics of biogas production and net energy were analyzed. The results indicated that organic removal in each group (M1, M2, T1, and T2) was 45.4%, 48.1%, 45.7%, and 48.5%, respectively, and gas production per gram of VS removed was 224, 233, 448, and 366 mL, respectively. The Gompertz model had the best fit, with the highest average R 2 and lowest root mean square error. The net energy used for digestion per ton of dry feces in each group was 398, 549, 805, and 771 kWh, respectively.


Phlebotomine sand flies (Diptera: Psychodidae) are the only known vectors of the bacteria Bartonella bacilliformis which causes Carrion Disease or human bartonelosis. The disease is only present in the Andean countries of Ecuador, Colombia and Peru. Hundreds of cases have been reported every year in northern Peru, however, the epidemiology, distribution of the disease and vectors incriminated at the Ecuadorian side are largely unknown. Reports from the 1950´s suggest that the disease is endemic in the southern region of Ecuador, nevertheless this contrasts with more recent data of very few cases reported in the last decades: 18 cases reported from the province of Zamora Chinchipe (Southern Ecuador) between 1995-1996, and 39 cases between 1995-2005. The objective of this study is to characterize the sandfly fauna of the area, examine for sand fly infection with Bartonella baciliformis and incriminate possible vectors. For this purpose, an entomological surveillance was conducted in the localities of Isimanchi, Pucapamba and Maniales (province of Zamora Chinchipe) through the use of CDC traps, the Mosquito Magnet trap and protected human bait. A total of 114 individuals were collected, of which 94.74% corresponded to Lutzomyia robusta, 4.38% to Lutzomyia maranonensis and 0.88% to Lutzomyia castanea. Specimens were examined by PCR and primers for the conserved regions of: (1) NADH dehydrogenase gamma subunit, (2) the 16s-23s intergenic sequence of the ITS rRNA (Internal Transcribed Spacer) and (3) Nested-PCR for the mitochondrial region of the Citrate Sintasa enzyme gene. Two and three positive samples were found using methods (1) and (2), respectively; results were further confirmed using method (3). Sequence analysis of the PCR products revealed the presence of Bartonella bacilliformis DNA, with 99% identity by method (1), and two positive samples for Bartonella bacilliformis with 93% and 99% identity respectively. Furthermore, one positive sample for Bartonella bovis with 91% Identity with method (2) was found. This is the first time that the infection of Bartonella bacilliformis in Lutzomyia robusta is reported, thus contributing to the incrimination of this species as a vector of the disease. The infection of Lutzomyia robusta with Bartonella bovis is reported as well. New studies are suggested at different times of the year to study seasonality, the possible transmission dynamics of the disease and evidence of active or subclinical human cases, and to expand the investigation to explore B. bovis infection in sand flies and its possible implications to cattle.


Drawing on the Bus Anthony Dubovsky January New soon proved a delight. Let me explain.

Fish is one of the main commodities consisting of style food in coastal areas of Yemen, but it is one of goods which play an important role in the food security of the population in Yemen. With increasing awareness of fish, became favorite in many provinces mountainous interior offshore Yemen, which led to an increase in demand for fish during the period of study and although there is self-sufficiency of the fish, that the average per capita consumption is 6.5 kg only, as the fish is the most important export commodities in Yemen, as the study showed that the annual rate of exports amounted to about 34 thousand tons with a total value of 10 million Ryals annually.


The sum‐over‐states (SOS), time dependent perturbation theory expansion over molecular eigenstates method for the computation of molecular hyperpolarizabilities is briefly reviewed. A correction vector method for the computation of linear and nonlinear optical properties of π‐conjugated systems has been devised for use with a singly and doubly excited configuration interaction model (SDCI). The SOS approach and the correction vector method are equivalent when the same basis set of many‐electron configurations is used in both. It has been verified that the values obtained from the correction vector method and by direct summation over eigenstates are identical. The correction vector method has been found to be very efficient for larger systems, both in terms of central processing unit (CPU) time and storage requirements. The direct SOS summation has been used to study the approach to the final SDCI values as excited states are added in order of increasing energy. Using the methods described in the previous ...


This article introduces a robust and computationally efficient technique for the design of fluctuation-resistant structures (fault-tolerant) semiconductor devices. This technique can be applied to the computation of the doping profiles that minimize the intrinsic variations in various parameters induced by random dopant fluctuations. The technique is based on the evaluation of doping sensitivity functions, which are defined as elements of the space adjoint to the space of square integrable functions generated by all possible doping variations. The optimized doping profiles are computed by minimizing the standard deviation of fluctuations of different parameters, and constraints are taken into consideration by using the Lagrange multiplier method. The technique introduced here can be applied to any semiconductor device, such as metal-oxide-semiconductor field-effect transistors (MOSFETs), silicon-on-insulator (SOI) devices, and fin field-effect transistors, and can be used in the framework of any transport...

Compressors of various types are estimated to consume around 20% of the electrical power generated in industrialised countries. The urgent need to accelerate decarbonisation of electricity generation and heating, combined with requirements for improving the energy efficiency of compression dependent systems and processes, is driving research in many different areas of compressor design, manufacture and operation. Compressors are key components in many heating and cooling processes, in refrigeration and air conditioning and in the process industries, while these machines, run in reverse as expanders, are increasingly used in systems to generate useful power from low grade waste heat sources. In many of these applications, they are required to operate on a continuous basis, day and night, throughout the year. Reliability and long service life must also be considered along with capital cost and efficiency in evaluating their worth. Consequently, despite the relative maturity of the industry, ever more detailed studies of the processes within existing types of machine are being undertaken, while novel means of effecting the compression process are continually being investigated. In recognition of these trends and for the benefit of industrial and academic participants, biennial international conferences on compressors and their systems are held at City, University of London, jointly convened with the IMechE, IIR and IOR. This special issue contains a small selection from the papers presented at the 10th and 11th international conferences on compressors and their systems. As can be seen, compressor research and development presented in the conference embraces the entire scope of Mechanical Engineering. The specimen papers published here, cover novel compressor configurations and geometry, lubrication and leakage effects, novel manufacturing methods, and expander performance. We, therefore, hope that this issue will be both of interest and value to the wider engineering public. Editorial


This study aims to investigate the electrodynamics of intra-cortical micro-electrodes and the effects of the different design parameters on the electrode electrical functionality. Finite difference time domain (FDTD) was used to create a low frequency electromagnetic model for the stimulation electrodes and the surrounding brain tissue. The paper also presents the effect of mechanical reinforcement metal planes on the electric field distribution within the brain tissue. The knowledge extracted from the simulation results will be used in the optimization of micro-electrode architectures and stimulation pads layouts in order to improve the electrodes functionality and biocompatibility.


Several manufacturers are adopting six sigma programs in efforts to reduce stamping variation. This requires the crucial step of establishing dimensional relationships for the stamping dimensional outputs that become key process inputs to the assembly process. This paper describes a methodology used to determine the root cause of dimensional changes in a front door assembly. Among the key findings in this study are the importance of understanding the effects of the datum-locating scheme and the significant influence of assembly processing variables, rather than stamping variability, on the final door assembly dimensional quality.


A hydrothermal approach has been developed for the synthesis of core-shell structured boehmite ultra-fine powders by using inexpensive Al2(SO4)3 aqueous solution and urea as raw materials,amiphiphilic copolymer of Poly(styrene)-block-Poly(2-hydroxyethyl acrylate)(P(St)-b-P(HEA)) as structure-directing agents. The hydrothermal product was characterized by techniques of X-ray diffraction(XRD), transmission electronic microscopy(TEM) and scanning electron microscope(SEM). The possible formation mechanism is discussed based on the experimental facts.

1. IntroductionIn the early period of the Cold War, Southeast Asia was in a state of political and social disorder. Returning colonial powers had problems to retain the control of their former colonial possessions and newly independent countries in the region were struggling with many internal difficulties. The power vacuum in Southeast Asia of the late 1940s was thus conducive for various interventions of great powers, including support for communist insurgencies. Soon after the establishment of the People's Republic of China (PRC) in October 1949, the ruling Chinese Communist Party (CCP) became the centre of a revolutionary struggle in Asia by providing ideological, economic and military support to various communist parties across Asia. Despite lack of sufficient contacts between the CCP and other Asian communist parties prior 1949 (except Indochina), Beijing quickly became the hub of revolutionary activity in this part of the world. As one of the key communist countries, China was eager to support ideologically related movements in Asia as part of its general strategy to lead global class war, where poor countries of the Third World would become the leading force for overthrowing colonial and capitalist forces. Southeast Asia was chosen as a centre of PRC's revolutionary activities because of its strategic location, geographical proximity, lesser presence of major powers, and still have weak colonial or newly independent governments. However, from China's opening to America in 1972 and with a general shift to more accommodating foreign policy under Deng Xiaoping (1904-1997) in the late 1970s, the support for communist insurgencies was widely scaled down by the CCP.In this paper, I will explore the motifs behind Chinese foreign policy in relation to PRC's support of communist insurgency and anti-government movements across Southeast Asia during 1949-1989. Was it caused by strongly ideological nature of Chinese foreign policy, or was it the result of China's search for security in unstable Cold War Asia environment? Or was it the result of both? Using the liberal theory of international politics, this paper argues that the PRC's role in the insurgencies should be seen as the consequence of shifts in Chinese foreign policy preferences. Until the 1970s the PRC understood revolutionary communist ideology as one of the main components of a state's identity. Insurgency support was a tool used to cement China's international status among the socialist countries as well as to weaken non-communist regimes, together with the superpowers backing them (the USA in the 1950s, both the USSR and the USA in the 1960s and the USSR in the 1970s and 1980s). Both military and ideological rivalry between the two superpowers was seen crucial by Chinese leaders, and their support for communist insurgencies followed larger international strategy. Since the opening to non-communist countries and Deng's rise to power, communist insurgencies became more of an embarrassment to the CCP. The reason was not the abandonment of ideology, but rather it took a new form, with presenting new goals as well as new enemies (Vietnam and the USSR instead of the USA, see He 1994).First part of this paper will describe the liberal theory of international politics. Second part will show overall trends in the development of Chinese foreign policy since 1949 until the end of the Cold War. The third part then deals with the characteristic of the post-Second World War Southeast Asia and its relations with communist China. Finally, part four will go in more detail through some cases of the PRC support of communist insurgencies in two countries (Thailand, Burma) in the region.2. MethodTo answer the question why China has supported various anti-government movements in Asia, I will first present my own analytical framework. Every attempt to explain foreign policy behaviour of a certain state could be theoretically understood by (a) systemic constraints on rational actors' behaviour and distribution of material capabilities, or (b) preferences generated by domestic politics. …


The crystal structures of bis(theophyllinium) tetrachloroplatinate(II)(A) and theophyllinium trichlorotheophyllineplatinate(II)(B) have been determined; the PtII atom is bound to N(9) in the complex (B).


The complete open reading frame(ORF) of cathepsin L was obtained from bay scallop(Argopecten irradians) by RACE technique.The ORF was of 1 095 bp,encoding 364 amino acids.Four conserved residues for enzyme activity(Q164,C170,H309,N329) and six preserved cysteines were found in the protein sequence.17 amino acids of N terminal were predicted to be the signal peptide and the sequence ASYPTV at C terminal was found to be a possible signal sequence.The mature protein of AICL contained 219 amino acids and the potential cleavage site was between A145 and M146.Analysis indicated AiCL shared the highest identities(50%) with molluscan cathepsin Ls.It clustered with other invertebrate cathepsin Ls in the phylogenetic tree.The 3D-model predicted by SWISS-MODEL demonstrated that cathepsin L was conserved in tertiary structure.Collectively,data showed that AiCL was likely to catalyze the hydrolysis of multiple muscle related proteins.


${\mathrm{Mn}}_{2}{\mathrm{O}}_{3}$ nanocrystals have been grown in a silica matrix following the sol-gel route and subsequent calcination at various temperatures in the range $700\phantom{\rule{0.2em}{0ex}}\ifmmode^\circ\else\textdegree\fi{}\mathrm{C}--900\phantom{\rule{0.2em}{0ex}}\ifmmode^\circ\else\textdegree\fi{}\mathrm{C}$. These nanocrystals have been studied by x ray and various magnetic methods including electron paramagnetic resonance (EPR). X-ray studies have revealed the presence of single-phase cubic $\ensuremath{\alpha}\text{\penalty1000-\hskip0pt}{\mathrm{Mn}}_{2}{\mathrm{O}}_{3}$ nanocrystals, the mean sizes lying in the range $9--18\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$. A large increment in the intensity and asymmetry of the EPR signal in lowering the temperature from room temperature to liquid-nitrogen temperature suggest that ${\mathrm{Mn}}_{2}{\mathrm{O}}_{3}$ nanocrystals become ferromagnetic (FM) at low temperatures. This is in sharp contrast with the observation of antiferromagnetic (AFM) ordering in bulk $\ensuremath{\alpha}\text{\penalty1000-\hskip0pt}{\mathrm{Mn}}_{2}{\mathrm{O}}_{3}$ crystals below $90\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. From zero-field-cooled (ZFC) and field-cooled (FC) magnetization and magnetic hysteresis measurements in the temperature range $5--300\phantom{\rule{0.3em}{0ex}}\mathrm{K}$ it has been established that $\ensuremath{\alpha}\text{\penalty1000-\hskip0pt}{\mathrm{Mn}}_{2}{\mathrm{O}}_{3}$ nanocrystals present in the calcined samples are superparamagnetic above the blocking temperature ${T}_{B}$ and weakly ferromagnetic below ${T}_{B}$. Small-sized nanocrystals are observed to have larger uncompensated magnetic moments. This is consistent with the postulate that uncompensated spins are present in a greater number on the surface of the antiferromagnetic inner cores of the smaller-sized nanomagnets. ac susceptibility experiments at various audio frequencies in the low-temperature region down to $5\phantom{\rule{0.3em}{0ex}}\mathrm{K}$, have confirmed the presence of magnetic-phase transitions in ${\mathrm{Mn}}_{2}{\mathrm{O}}_{3}$ doped silica samples (calcined at various temperatures) at low temperatures and have also provided evidence that $\ensuremath{\alpha}\text{\penalty1000-\hskip0pt}{\mathrm{Mn}}_{2}{\mathrm{O}}_{3}$ nanocrystals grown in the silica matrix are best described as an assembly of randomly frozen nearly noninteracting magnetic particles.


Context: Humic acid (HA), a naturally occurring chemical compound, is now being studied for medicinal applications. Paclitaxel (PTX), a strong anticancer agent, has a low water solubility, resulting in limited bioavailability following oral administration, improper tissue localisation, and poor therapeutic use. The goal of this study is to see if PTX can be complexed with HA to improve its solubility and bioavailability effectiveness. Materials and procedures: Differential scanning calorimetry, Fourier Transform Infrared spectroscopy, X-ray diffraction, and scanning electron microscopy were used to analyse complexes produced by solvent evaporation in varied weight ratios. Conclusion: Using HA to enhance the solubility and bioavailability of medicines is a beneficial method.


This study was performed in order to evaluate the neuroprotective effect of Boyanghwano-tang (BYT) water extract on intracerebral hemorrhage (ICH). ICH was induced by the stereotaxic intrastriatal injection of bacterial collagenase type IV in Sprague-Dawley rats. BYT was orally given once a day for 3 days after ICH. Hematoma volume and percentage edema were examined. As imflammatory markers, myeloperoxidase (MPO)-positive neutrophils infiltration and iNOS expression in the peri-ICH regions were examined using immunohistochemistry. As cellular damage markers, c-Fos, Bax, and HSP72 positive cells in the peri-ICH regions were measured also. BYT significantly reduced the hematoma volume and percentage edema of the ICH-induced rat brain. In the peri-hematoma regions, BYT significantly reduced MPO-positive neutrophil infiltration and iNOS expression of the ICH-induced rat brain. Additionally, BYT significantly reduced c-Fos, Bax, and HSP72 positive cells in the peri-hematoma regions of the ICH-induced rat brain. These results suggest that BYT plays a neuroprotective role against ICH through suppression of inflammatory responses, apoptosis and cellular damage.


On the surface, through the "One Belt, One Road" and the BRICS' New Development Bank, China is promoting a transformative vision of international order based on equality among states, fairness in international institutions and trade and development without conditionality requirements as the engine of economic growth and peace. By deploying the concept of Market State as developed by Patterson and Afilalo in their work on the global trade order, this article aims to show that the nature of China's contribution to global governance appears to be much less transformative and future-oriented than declared once we place it in the broader context of a world society and changes in the capacities of states.


An electrolytically recharged sleeve exploder was fired at depths between 15.2 m and 51.8 m in a 200-mm diameter, steel‐cased, water‐filled shallow borehole in Hopkins County, Texas. Oxy‐hydrogen explosive gas charges were varied between 30 and 170 kJ. Seismic traces revealed three distinct, delayed, anomalous arrivals. Two of these moved out nonlinearly with increasing charge. The fact that the anomalies were not peculiar to gaseous sleeve explosions was confirmed by repeating part of the experiment using small high explosive charges. The anomalies appear to stem from the collapse of cavities that are created by shock waves. A model is advanced, in which up‐ and downgoing shock fronts sweep away from the explosion at the tube wave velocity. They reflect from the free and plugged ends of the borehole. Reflection at the free end transforms an upgoing overpressure into a downgoing rarefaction. Momentum transfer surges the fluid. Surges accumulate. Two rarefaction shocks eventually collide at the shot point....


This paper reports the Detector Control System (DCS) of a Cylindrical Gas Electron Multiplier (CGEM) detector, which is the upgrade of the inner tracker detector of BESIII. A dedicated powerful online DCS is required to ensure the safety and correct operation of the CGEM system, which is distributed on several subsystems, including low and high voltage power supplies, front-end electronics, environmental sensors, gas and cooling infrastructure. This paper presents the hardware architecture and software solutions adopted and the evolution along with the results in commissioning phase in the laboratory will also be discussed.


The supply chain is the basis for the functioning of today's society because it ensures the timely supply of all the resources needed to produce products or provide services offered in the market. Due to changes in the environments in which the supply chain exists, new risks arise that could jeopardize its functioning. Interruption in the normal functioning of the chain may result in the risk of inability to meet the requirements of stakeholders. Given this, the aim of this paper is to define a conceptual model of supply chain resilience management. The paper is based on the conducted secondary research and analysis of the achievements of other researchers in this field. The model described in this paper is based on the principles of the quality management system and provides a systematic approach to the analysis of supply chain threats, defining measures to reduce the threat, and testing and improving the established system.


Cleaning with chemicals can certainly be a cause for concern! Chlorine is a toxic, yellow-green gas that's one of today's most heavily used chemical agents. Many household cleaners contain chlorine, including automatic dishwashing detergents, some laundry detergents, chlorine bleach, chlorinated disinfectant cleaners, mildew removers, and toilet bowl cleaners. As for mixing products, more isn't always better — unless a chemist is the one mixing, it's recommended that household cleaners aren't combined. Depending on the mixture, chlorine may be released, which can lead to poisoing and may even be fatal. If, while cleaning, someone inhales or ingests chlorine or starts to experience physical symptoms, stopping use of that particular product and seeking care from a medical professional is advised.


Forceful anticorruption campaigns are common in authoritarian regimes but systematic evidence on how they actually work remains limited. We develop predictions about the patterns of enforcement based on the two fundamental challenges faced by autocrats: (1) containing mass discontent from below and (2) eliminating challengers within the elites. We test these predictions using both aggregate enforcement data (1988-2014), and a new dataset that tracks the political fates of over 3000 Chinese officials from 2000 to 2015. We find that the overall intensity of anticorruption is inversely related to the regime's economic performance, and individual-level investigations systematically shun away from clients of incumbent leaders while disproportionately targeting those affiliated with incumbents' rivals. Additional tests suggest that the discrepancy in enforcement cannot be explained by differential corruptness alone. Finally, we find that the recent anticorruption initiatives by Xi Jinping has led to a significant centralization of power within a smaller inner circle.


ABSTRACT
 This article examines the political deification of Harichand and Guruchand Thakur, the founders of an anti-caste religion called Matua Dharma, in contemporary West Bengal. The religious community of the Matuas, who are mostly Namasudras (an ex-Untouchable caste), have drawn considerable public attention over the last two decades as a politically organised and electorally salient group. Drawing from fieldwork evidence and observations, the article shows that a key strategy behind the consolidation of Matuas as a political public has been the use of symbolic means and projection of Harichand-Guruchand as regional icons of Dalit politics by their community organisation, viz. the Matua Mahasangha, and other political actors. The article explores these processes of deification of Harichand and Guruchand Thakur and the consequent making of a Matua political public by looking at three areas – (a) Matua print literature, (b) community festivals, and (c) commemoration practices at the popular and official-institutional levels.


The troubles from the practice of the administrative petition system of our country are due to the fact that its consultative ration is not legally demonstrated.Thus,the aim for our country's reform of administrative petition system should be to construct administrative petition as demonstration and to increasingly strengthen the platform of administrative consultation system in the legal context of modern administration.Only by strengthening administrative consultation can the retrieval of value for our country's administrative petition and the demonstration of system ration be promoted,so as to make administrative petition highlighted in the consultative ration between administrative body and citizens,to promote the two sides of the main bodies in perfect interaction,to make rational cooperation active and to push the development of our country's administrative rule by law and good governance.


We carry out a comprehensive smooth particle hydrodynamics simulation survey of double-degenerate white dwarf binary mergers of varying mass combinations in order to establish correspondence between initial conditions and remnant configurations. We find that all but one of our simulation remnants share general properties such as a cold, degenerate core surrounded by a hot disk, while our least massive pair of stars forms only a hot disk. We characterize our remnant configurations by the core mass, the rotational velocity of the core, and the half-mass radius of the disk. We also find that some of our simulations with very massive constituent stars exhibit helium detonations on the surface of the primary star before complete disruption of the secondary. However, these helium detonations are insufficiently energetic to ignite carbon, and so do not lead to prompt carbon detonations.


A quadratic equation for the temperature-independent Gruneisen coefficient y was derived by a method in which the Walsh-Christian and Mie-Gruneisen equations are combined. Some previously existing ah initio temperature Hugoniots for hexagonal close-packed solid Fe are inaccurate because the constant-volume specific heats on the Hugoniots C V H , which are related uniquely to the solutions of the quadratic equation, have values that are too small. A CAN distribution in the solid phase range was demonstrated to agree approximately with a previous ab initio distribution. In contrast, the corresponding y distribution was significantly different from the ab initio distribution in the lower pressure region, and the y distribution in the liquid phase range had a considerably larger gradient than the ab initio distribution. The causes of these disagreements are clarified.

Soil is naturally occurring material that is used for the construction of pavements. Soil is a variable material and exhibits different properties in the different regions and becomes a challenge for the construction of roads sometimes. Hence detailed understanding of the nature of the soil in the site and its behavior as a subgrade material has to be properly assessed. Three types of soils are used for the present study namely, Black cotton soil, Gravelly sand and sandy soil. Their characteristics are assessed to decide its suitability as a road material. In-situ soil density measurement has been conventionally done using sand replacement and core cutter methods. There is an invent of a new gauge called the Non-nuclear soil density gauge which is getting popular nowadays in the determination of field density. In the present study an attempt is made to compare the densities obtained by the three different methods by varying the lift thickness of 150mm and 300mm as per MORT&H specification. The compaction of the soil is done with a rammer of size 20cm x 15cm with required number of blows. The density results obtained from the different approaches have been correlated and compared.


Based on physiological investigations, Nicholls and Baylor (1968) identified and described three types of mechanosensory neurons in segmental ganglia of medicinal leech: T-cells receiving touch information, P-cells sensitive to changes in pressure applied on the skin, and N-cells affected by nociceptive stimuli. The electrical excitability and the passive electrical parameters of the somatic membrane of mechanosensory neurons have been thoroughly investigated (Baylor and Nicholls 1969a, b, c; Jansen and Nicholls 1973; Fuchs et al. 1981). Differences have been observed in the electrical pattern between different types of mechanosensory neurons. T-cells were found to differ from the other types of the leech neurons also by their sensitivity to some drugs that alter the function of the voltage-dependent ionic channels (Kleinhaus and Prichard 1983; Johan-sen and Kleinhaus 1985). Attempts to determine the characteristics of the different types of leech neurons under voltage-clamp conditions using single-or double-barrelled microelectrodes came up against some difficulties (Kleinhaus and Prichard 1983). We applied the methods of intracellular perfusion and voltage-clamp to study the ionic mechanisms of excitability of the somatic membrane of leech neuron under controlled external and internal ionic conditions. The experiments were carried out on type T-mechanosensory neurons isolated from segmental ganglia of medicinal leech. Ganglia from Hirudo medi-cinalis were treated with 0.3 % Pronase E, dissolved in standard leech Ringer solution (Table 1, bottom), for 20 min at 18—20 °C. After the treatment, the ganglia were transferred to the standard solution and kept there for 60 min at 4°C. Using finely sharpened metal needles, the connective tissue sheaths covering the ganglion were torn in several places as far as possible from the selected neurons and carefully removed from the glial packets with nerve cell bodies


Reproducible ultrahigh SERS enhancement in deterministic plasmonic hotspots allows chemical events on the single molecule level to be observed in real time, including plasmon-driven dimerization of 4NBT to DMAB, DMAB desorption and trans-cis conformation switching.


Fluoride phosphate glasses with different phosphate contents and metaphosphate glasses, both with different Er 3+ concentrations of 3 to 10 . 10 19 cm −3 , were prepared. The lifetimes and the intensities of the fluorescence transitions 4 S 3/2 → 4 I 15/2 at 540 nm and 4 I 13/2 → 4 I 15/2 at 1.5 μm have been studied as a function of phosphate content and Er 3+ concentration. The results have be discussed by considering the rates of radiative decay, multiphonon relaxation, cross relaxation and energy transfer to hydroxyl groups. Furthermore, laser action of some fluoride phosphate glasses via krypton ion laser pumping was achieved


This paper intends to test for the existence of credit channel of monetary policy in Australia using aggregate seasonal data from 1994.1 to 2011.4. Based upon Johansen trace test, two co integrating relationships are found and can be identified respectively as loan demand and supply functions. With the tests for a number of exclusion and exogeneity restrictions, the paper concludes that loan supply is negatively related to interbank cash rate, suggesting the existence of credit channel of monetary policy in Australia. Furthermore, a shortterm dynamic analysis shows RBA plays an important role in equilibrium-correcting in the supply of loan. And inflation rate is also found to be equilibrium-correcting in the long run supply equation.


This article reports the organomodification of Indian bentonite clay with three modifiers and the fire behavior of organomodified Indian bentonite clay/vinylester/glass nanocomposites. Indian bentonite (Na-IB) clay was organomodified using hexadimethyl ammonium bromide (HDTMA-Br), tetra-n-butylammonium bromide (TBA-Br) and triphenyl methyl phosphonium bromide (TPP-Br) by varying the cation exchange capacity. Basal spacing of 34 Å was observed in Na-IB modified with HDTMA-Br (HDTMABr-IB) followed by 28 Å in Na-IB modified with TPP-Br (TPPBr-IB) and 26 Å in Na-IB modified with TBA-Br (TBABr-IB). Fourier transform infrared spectra of HDTMABr-IB confirmed the attachment of functional groups, its zeta potential increased from −36.34 to 5.35 mV indicating greater surface potential and thermogravimetric analysis showed greater weight loss confirming Na+ ion exchange with alkyl amines. Energy-dispersive X-ray analysis showed compositional changes between modified and unmodified clay with the presence of 37.03% carbon in the HDTMABr-IB. Horizontal and vertical burning rates of vinylester/glass composites decreased with the addition of HDTMABr-IB. Limiting oxygen index increased by 40% with the addition of 5 wt% HDTMABr-IB to vinylester/glass.

In Japan, there are no suitable training materials for community and hospital pharmacists to increase a common understanding for pharmaceutical care on several diseases. We therefore developed to following training materials consisting of 8 components, 1. Charts of case studies, 2. Items of pharmaceutical managements, 3. Items of pharmaceutical services, 4. Sheets for recording of medical history, 5. Sheets for drug information of patients, 6. Sheets for contents of pharmaceutical services, 7. Confirmation sheets for essential drugs and 8. Check sheets for essential drugs on 6 diseases, such as deep-vein thrombosis, myocardial infarction, hypertension, non-insulin-dependent diabetes, bronchial asthma and gastric ulcer. In the present study, to evaluate the usefulness of this system, a questionnaire regarding the benefit of "1. Charts of case studies" on community and hospital pharmacists selected randomly was conducted and analyzed. Community pharmacists recognized the style of these charts to be highly advantageous, while hospital pharmacists were interested in explanations for medical treatments. Furthermore, almost all pharmacists answered the usefulness of case studies for understanding pharmacotherapy. These findings showed the usefulness of using the "1. Charts of case studies" for the initial training of clinical works as a pharmacist.


High Energy Physics (HEP) software environments often involve ∼ hundreds of external packages and libraries, and similar numbers of experiment-specific, science-critical packages—many under continuous development. Managing coherent releases of the external software stack is challenging enough, but managing the highly-collaborative—and distributed—development of a large body of code against such a stack adds even more complexity and room for error.
Spack is a popular Python-based package management tool with a specific focus on the needs of High Performance Computing (HPC) systems and system administrators whose strength is orchestrating the discrete download, build, testing, and installation of pre-packaged or tagged third-party software against similarly stable dependencies. As such it is becoming increasingly popular within HEP as that community makes increasing use of HPC facilities, and as efforts to develop future HPC systems utilize Spack to provide scientific software on those platforms [1].
SpackDev is a system to facilitate the simultaneous development of interconnected sets of packages. Intended to handle packages without restriction to one internal build system, SpackDev is integrated with Spack as a command extension in order to leverage features such as dependency calculations and build system configuration, and is generally applicable outside HEP. We describe SpackDev's features and development over the last two years, initial experience using SpackDev in the context of the LArSoft liquid argon detector toolkit, and work remaining before it can be considered a fully-functional multi-package build system for HEP experiments utilizing Spack.


Variable flux reluctance machines (VFRMs) are viable candidates for automotive applications. This paper investigates the field weakening capability of a 12/10 VFRM. Starting with voltage and toque equations, the paper reveals the relationship between torque-speed characteristics and the current arrangement (slot division) of both DC-field and armature windings. The method for expanding the working envelope by tuning DC or AC currents is discussed for different slot divisions. The results are validated by 2D finite element analysis.

During the past decade, several new upper atmospheric phenomena associated with thunderstorms have been discovered. The four main types of optical emissions are now called sprites, blue jets, elves, and halos. Sprites are primarily red and appear between 40-95 km altitude and last between 1-100 ms. The dominant sprite emission is the molecular nitrogen first positive band, a relatively low energy emission also observed in the red lower borders of aurorae. The total optical energy output of a bright sprite is on the order of 50 kJ. Based on spectral observations, the total vibrational and electronic energy deposited in molecular nitrogen and oxygen in the upper atmosphere is 250 MJ-1 GJ. Blue jets last hundreds of milliseconds and span altitudes 15-40 km. Spectral observations of blue jets have not been obtained to date. Elves, the third type of observed optical emissions above thunderstorms, are red emissions at altitudes 75-95 km, lasting one millisecond or less. Elves and halos are similar phenomena, but are distinct based on altitude and duration. Halos typically last 3-6 ms and occur at lower altitudes than elves. This dissertation describes the optical spectrum of sprites obtained by the University of Alaska Fairbanks during summer campaigns of 1995, 1996, and 1998, and its implication to the understanding of the electrodynamics of the middle atmosphere. The single most significant result is the determination that a typical sprite deposits up to one gigajoule into the mesosphere. These forms of electrical energy coupling from tropospheric thunderstorms into the stratosphere, mesosphere, and thermosphere/ionosphere may have critical implications for the global chemistry and energy budgets in these regions.


In this experimental study, we selected 6 males long jump players at high school. For the purpose of analyzing take-off movement in the long jump, we used video-camera and made a kinematical analysis. Within the limitations of this study it is concluded: In order to increase flight distance, several conditions must be fulfilled at the instant of takeoff leg touchdown and takeoff during takeoff phase. 1. the takeoff velocity should be fast at the instant of takeoff leg touchdown and takeoff. The body center of gravity height should be raised at the instant of takeoff leg touchdown and takeoff. 2. the foot contact time should be shortened during takeoff phase and the takeoff distance should be increased at the of takeoff. 3. the total forward angular momentum with respect to a transverse axis through the center of gravity should be increased during the takeoff leg touchdown and takeoff. The active landing style described as clawing the ground with the sole of the takeoff foot should be performed during the takeoff leg touchdown and takeoff.

Protein kinase B (Akt/PKB) is a key component in the PI 3‐kinase mediated cell survival pathway and has oncogenic transformation potential. Although the over‐expression of PKB‐α can prevent cell death following growth factor withdrawal, the long‐term effects of stable over‐expression of PKB‐α on cell survival in the absence of growth factors remain to be resolved. In the present study, we generated HepG2 cells with stable expression of active PKB‐α and compared its characteristics with HepG2 cells. Basal as well as insulin‐stimulated levels of Ser473 and Thr308 phosphorylation in PKB‐α transfected HepG2 cells were much higher than HepG2 cells. Constitutive expression of active PKB‐α enabled HepG2 cells to survive up to 96 h without serum in growth media while HepG2 cells fail to survive after 48 h of serum withdrawal. A strong positive correlation (R2 = 0.71) between cell proliferation and phosphorylated form of PKB‐α at Thr308 was observed along with higher levels of phosphorylated 3′‐phosphoinositide‐dependent kinase‐1 (PDK‐1). HepG2 cells with constitutive expression of active PKB‐α also showed higher levels of phosphorylated p65 subunit of nuclear factor‐κB (NFκB) in comparison with HepG2 cells. Predominant nuclear localization of phosphorylated PKB‐α was observed in stably transfected HepG2 cells. These results indicate that constitutive expression of active PKB‐α renders HepG2 cells independent of serum based growth factors for survival and proliferation. © 2004 Wiley‐Liss, Inc.


The propensity interpretation of fitness (PIF) is commonly taken to be subject to a set of simple counterexamples. We argue that three of the most important of these are not counterexamples to the PIF itself, but only to the traditional mathematical model of this propensity: fitness as expected number of offspring. They fail to demonstrate that a new mathematical model of the PIF could not succeed where this older model fails. We then propose a new formalization of the PIF that avoids these (and other) counterexamples. By producing a counterexample-free model of the PIF, we call into question one of the primary motivations for adopting the statisticalist interpretation of fitness. In addition, this new model has the benefit of being more closely allied with contemporary mathematical biology than the traditional model of the PIF. 1 Introduction   1.1 The 'Generality Problem'   1.2 Counterexamples to the PIF    1.2.1 The moments problem    1.2.2 The delayed selection problem    1.2.3 Timing of reproduction   1.3 The need for a new model 2 A New Formalization   2.1 The new model and biological theory 3 Possible Objections to   3.1 Objection 1: Natural selection is short term   3.2 Objection 2: Descendants are only minimally related to ancestors   3.3 Objection 3: Evolutionary time scale is pragmatically determined   3.4 Objection 4: Long-term fitness is lineage fitness   3.5 Objection 5: The theory of evolution by natural selection fundamentally concerns trait fitness, not individual fitness 4 Response to Counterexamples   4.1 Timing of reproduction   4.2 Delayed selection   4.3 The moments problem 5 Conclusion 1 Introduction   1.1 The 'Generality Problem'   1.2 Counterexamples to the PIF    1.2.1 The moments problem    1.2.2 The delayed selection problem    1.2.3 Timing of reproduction   1.3 The need for a new model   1.1 The 'Generality Problem'   1.2 Counterexamples to the PIF    1.2.1 The moments problem    1.2.2 The delayed selection problem    1.2.3 Timing of reproduction    1.2.1 The moments problem    1.2.2 The delayed selection problem    1.2.3 Timing of reproduction   1.3 The need for a new model 2 A New Formalization   2.1 The new model and biological theory   2.1 The new model and biological theory 3 Possible Objections to   3.1 Objection 1: Natural selection is short term   3.2 Objection 2: Descendants are only minimally related to ancestors   3.3 Objection 3: Evolutionary time scale is pragmatically determined   3.4 Objection 4: Long-term fitness is lineage fitness   3.5 Objection 5: The theory of evolution by natural selection fundamentally concerns trait fitness, not individual fitness   3.1 Objection 1: Natural selection is short term   3.2 Objection 2: Descendants are only minimally related to ancestors   3.3 Objection 3: Evolutionary time scale is pragmatically determined   3.4 Objection 4: Long-term fitness is lineage fitness   3.5 Objection 5: The theory of evolution by natural selection fundamentally concerns trait fitness, not individual fitness 4 Response to Counterexamples   4.1 Timing of reproduction   4.2 Delayed selection   4.3 The moments problem   4.1 Timing of reproduction   4.2 Delayed selection   4.3 The moments problem 5 Conclusion


With reference to the use of paraffin for the duralumin tubes, Wayne Paulsen has referred to a new base-varnish for skis developed in South America. This varnish has a bakelite base and it goes under the name of "Risch-Rasch." Paulsen stated that, in his experiments with it as a coating for the duralumin tubes, he was having trouble getting a smooth finish on the inside. It is suggested that the plunger-method be used as described above in "California Cooperative Snow-Surveys: Directions, suggestions, and hints for snow-surveyors."


The merits of the justice reinvestment approach adopted in the United States and the United Kingdom to divert funding from correction budgets for investment in programs to reduce criminal behaviour in communities with a high rate of criminal offense are discussed, also analysing its potential for application in the Indigenous context in Australia. It is suggested that the approach is a worthy replacement to costs of Indigenous over-imprisonment, also being in line with policy aims to fulfill the social and economic needs of Indigenous communities.


JING makes two major points. First, the variance in earnings for an occupation is largely unexplained even after consideration of sex, age, and education and as a consequence, the present value rankings may prove to be misleading guides to occupational choice. Many people would prefer lower-valued occupations if they have smaller variance and therefore present less salary risk.' Secondly, he concludes that since people have a diminishing marginal utility for income, it is very difficult o "approximate statistically the subjective comparisons being made in the market by individuals." King misunderstands the main purpose of the original article. Let us consider his second point first. We wished to provide information which could be readily used by individuals in making choices. Different individuals will have different subjective evaluations concerning how much the marginal utility of income diminishes for them. Some people will regard small differences in present value as more important than others might. It was not our purpose to consider any general estimate of diminishing marginal


In this paper, we propose a mid-range wireless power transfer system with CCL type resonant topology on source side for monitoring equipment power supply on electricity pylons. In consideration of low coupling coefficient caused by long transmission distance, a relatively high current level should be kept when using the traditional serial-serial topology(referred to as S-S topology), which increases the system energy loss and rise the breakdown risk on switching devices. The CCL topology could provide a relatively high equivalent impedance and still keeps the current on transfer coil high enough. The characteristic of this topology and the analysis of system efficiency at different load are given. The experiment result shown at in last part proves the availability of this topology.


An analysis and design concept for the dual-band orthomode junction is presented. The centerpiece of the design is a waveguide six-port cross junction. Its modal analysis is verified by measurements available in the literature. After introducing appropriate symmetry planes for the orthomode junction, a principal design approach is outlined. The entire procedure is demonstrated for a K/Ka-band design example. The final design is compared to results from the commercial software package HFSS and is found to be in good agreement.


This population-based longitudinal questionnaire study examined whether back beliefs predicted increased low back pain (LBP) one year after baseline, comparing the phenomenon in nurses versus other participants. A random sample of 2'860 individuals participated. At one-year follow-up 1'445 questionnaires were returned. At baseline and follow-up, back beliefs were assessed with the Back Beliefs Questionnaire (BBQ) and LBP was assessed using a standardized pain intensity item and pain manikin. Cross-lagged structural equation modeling was used to estimate the prospective risk path from BBQ at baseline to LBP at follow-up. A model comparison test evaluated whether paths differed between 59 nurses and 1'383 other respondents. The cross-lagged path model fitted the empirical data well (CFI = 0.91; RMSEA = 0.04). In nurses, the longitudinal path from BBQ to LBP at follow-up (β=0.30, p=.013) and the cross-sectional association between BBQ and LBP at follow-up (β = 0.42, p = .031) were more positive than in others (longitudinal path: β = 0.05, p = .023; cross-sectional path: β = 0.06, p = .062). The biopsychosocial model of LBP and maladaptive back beliefs should be addressed in educational occupational health interventions for nurses.


This paper proposes a learning-by-doing (LBD) system for assisting learners of English as a foreign language, by providing educational content generated based on real-world behaviors in a sensorized environment. The LBD system consists of an ultrasonic location sensing system developed by the authors and an educational content server. The location of the student is monitored by ultrasonic sensors embedded around the learning room. The system voices English verbs related to objects around the student so that the student can obtain the language skills for expressing various activities of everyday life in English by performing real-world behaviors. The system was implemented experimentally in an English language school. Six subjects participated in an experiment evaluating the educational efficacy of the proposed system. Recall rates of learned verbs were compared among three methodologies, "learning by text," "learning by pictures and text," and "learning by doing". Recall rates were measured at the following intervals: soon after the learning task, 2 days after, 4 days after, 7 days after, and 14 days after the learning task. The results indicate that the proposed LBD system increased the recall rate of learned words by 113% 14 days after the learning task. Overall, the system significantly increased the average recall rate by 102% in comparison to the other learning methodologies.


Although collective action is always backed by some line of reasoning, the study of this type of argumentation, and the sociological study of forms of protest, are disciplines that largely ignore each other. This academic division of labor is surprising given that both disciplines examine the regularities and patterns that protest displays over long periods of time. Study of argumentation reveals that limited number of lines of argument are used by successive generations of actors in different contexts. However, the sociohistory of protests—"as inspired by Tilly's works"—highlights that these actors hold to a specific "contentious repertoire" when they take action on a given cause. This paper considers the methodological issues and specific theoretical difficulties raised by combining both approaches and what new perspectives and insights this yields, particularly with respect to the various timeframes underlying social conflicts: that of the social actors themselves, and the longer timeframe for varied forms of action, types of discourse, and arguments put forth by these actors, constantly readjusted to suit fresh circumstances.


D in the bush of Malawi, Central Africa, on the edge of what is still the small village of Embangweni, stands a simple stone cross, inscribed with the words "In memory of Donald Fraser and Jonathan Chirwa." Here, side by side, in what was the chief's cattle kraal-the place of burial for those held in particular esteem among the cattle-herding Ngoni people-lie the Scottish missionary and his Malawian colleague. Fraser died in Scotland on August 20, 1933, following an operation for the removal of his gall bladder. He was cremated, and his ashes were brought back to Malawi by his wife for burial at the place of his missionary service. The positioning of the graves bears witness both to the respect with which the Ngoni people regarded Fraser and to the affection that he himself had for those among whom he worked. Today Donald Fraser is not widely known outside Malawi and Scotland. Yet in his day he was both active missionary and internationally known mission strategist, friend and colleague of men like John R. Mott and Joseph H. Oldham, and many of his insights into both the theory and practice of mission remain valid, and valuable, for us today.


Performance predictions from wireless networking laboratory experiments seem to dismatch what is really deployed. To generate realistic traffic is one of the major factors hampering researcherspsila ability to make reliable forecasts. This paper reports on the results of a multiscale analysis of traffic traces captured at an infrastructure 802.11g wireless network. The analyzed traffic is characterized by a non self-similar process for small time scales and strong self-similarity for larger time scales. For smaller time scales, the packet arrival times are independent explaining the weak correlation of the data. For larger timescales the arrival of TCP connections can be considered independent. Additionally, we propose a model which allows generating traffic similar to the measured traffic. The model contains only multiscale index allowing influencing all observed changes in LD and variance-time plots. Comparing the output of the model with the real traffic traces we find that the model matches reality accurately.

Objective: To study the effects of neem kernel powder(NP) and glibenclamide. alone or in combination, on alloxan diabetic rats.

Methods: The diabetic rabbits were given with NP alone or in combination with glibenclamide for thirty days and at the end of thirty days the serum lipid levels, blood glucose and activities of some serum, liver and intestinal enzymes were assessed.

Results: Administration of NP alone (500 mg/kg) as well as the combination of NP (250mg/kg) with glibenclamide (0.25mg/kg) significantly decreased the concentration of serum lipids, blood glucose and activities of serum enzymes like alkaline phosphatase (alk P), acid phosphatase (acid P), lactate dehydrogenase (LDH), liver glucose 6-phosphatase (G6P) and HMG CoA reductase activity in liver and intestine of alloxan diabetic rabbits. However, all the treatments produced an increased liver hexokinase activity. The changes observed were significantly greater when the treatment was given in combination of NP and glibenclamide than with NP alone.

Conclusion: Our data suggest a significant antidiabetic and antihyperlipaemic effect of NP in alloxan diabetic rabbits.
