It is the purpose of this study to review in brief the changes that have taken place since the turn of the century in content of mathematical studies in the high school and to examine theoretically the significance of such changes.


The research was conducted in the granite mining sites of Kerala to determine the effect of mining on the health of two tropical plants namely Macarangapeltata and Chromolaenaodorata which were common to the area. The area having high amount of particulate matter in the working hours of the quarry. The plants were severely affected by the mining activities. In this study, it was observed that the quarry dust was affecting the Chromolaenaodorata, as it is having chlorophyll lower than the control sites.Chromolaenaodorata present in the quarry sites having retarded growth compared to control site plants. In the case of Macarangapeltata, samples showed higher concentration of chlorophyll than control to cope up with the stress.

The ideal of an ethical cosmopolitanism (Seyla Benhabib) allows for the simultaneity of human rights and plurality. This underlying paradigm of universal human rights, which include, indeed underscore difference, has also been the foundation of recent cultural transfer studies. Michel Espagne coined in the 1980s the term "cultural transfer," which originated primarily in the history of translation and the circulation of knowledge between France and Germany in the nineteenth century and later was widened to triangular relationships. Espagne was interested in varied, often reciprocal cultural interactions, complicating nineteenth-century theories of cultural comparison to the study of forms of cultural mixing, interpenetration, and hybridization. Moving beyond the idea of the dominant center and the receiving peripheries, recent work on cultural transfer acknowledges the complex interaction between different cultural spheres to effect what Espagne calls "métissage" and "imbrication" (Les transferts culturels franco-allemands [1999, 1-49, 267-70]).


The present study was undertaken to confirm and extend previous observations on the use of morphine‐induced Straub tail and rotarod performance in mice as a means of assessing the efficacy of a compound as a muscle relaxant and its potential for depressant side‐effects, respectively. The ratio of the rotarod to Straub tail ED50s was calculated as an index of specificity. Our results generally confirmed previous reports in the case of diazepam, chlordiazepoxide and dantrolene. Additionally, the recently introduced muscle relaxants, cyclobenzaprine, baclofen, and DS 103‐282 were found effective in blocking Straub tail and their reported clinical specificity was reflected by the specificity observed in the mouse tests. DS 103–282 was found to be the most potent and specific. It is concluded that muscle relaxants with specificity ratios significantly greater than 1.0 appear to have comparatively few depressant effects at therapeutic doses. The relatively simple methods used in the present study appear to be useful in the initial assessment of compounds as potential muscle relaxants.


This diploma thesis deals with preparation and study of physico-chemical
properties of chalcogenide glasses and thin amorphous films of Ge 20Sb10S70-xSex
system, where x = 0, 10, 20, 30 and 40). Thin layers were prepared by thermal
evaporation. Optical properties and structure of bulk glasses and thin films were
studied and their changes induced by exposure of thin films with polychromatic
light of halogen lamp and by annealing under the temperature of glass transition
were discussed.


235 U/ 238 U in the studied samples were calculated on the basis of the measurement of the count rate of 185.7 keV gamma line of 235 U and 1001 keV gamma line of 234m Pa, a first daughter of 238 U. It was found that, the specific count rates of 235 U, and 238 U were constant regardless of 235 U enrichment. A good agreement was found between the calculated and the measured values of the activity ratios of 235 U/ 238 U. A strong correlation (0.9982) was found between the certified and the measured enrichments. The results obtained from these analyses shows that this suggested analytical method can be used to determine the uranium concentration, and the isotopic abundance, especially in the case of depleted, natural and low enriched uranium samples.


with the complicity of the citizenry. The life of the Constitution is not Schmittean logic; it is the experience of actors who talk and respond to one another in a public space. Constitutional limitations are not formal but a function of how power is constituted and deployed by such actors. From the perspective of the citizen, the culture of emergency has resulted in what Meyers calls civic war and the tendency toward monocracy. In contrast to the violent character of an armed engagement between combatants, civic war refers to the experience of citizens who are placed under the thumb of necessity and discouraged from exercising their judgment. Civic war refers not only to the level of social coordination and cooperation that is needed to support combatants but also to an ongoing "domestic way of life" in which the citizenry is reduced to complicity and silence. The violence of civic war is internalized by the repetition of images (the planes hitting the Twin Towers) and claims ("everything is different") that generate a continual fear that can be played upon and manipulated. Through the symbolic weight of the idea of crisis, the executive has found its opportunity to consolidate and unify power. The president, however, cannot consolidate power alone. To explain why this is so, Meyers introduces the phrase "the division of action" to "hold emphatically before our eyes that all human action takes shape and force from a context composed of other human beings" (p. 22, fn.). Beneath our constitutional procedures is "the fundamental social fact" that citizens must also be brought along and transformed by the actions of the executive. "Civic war is a particular division of action" (p. 261). It is a division of action in which citizens are complicit in the executive's decisions. It is a form of corruption, a kind of political suicide in which the possibility for politics is being denied at the very time that politics is being engaged. For Meyers, the executive needs to play us just as the terrorist needs to play the government. In both cases, the goal is to leave the target speechless, stunned, and docile enough to carry forward someone else's agenda. The author's general analysis of politics in America is partly fueled by his disdain for and criticism of the Bush administration. But if what he sees as the fanaticism of that administration is taken to intensify the tendency towards monocracy, the lessons Meyers draws are meant to describe both a more enduring state of American political culture and a possible source of renovation. In the former case, his analysis would suggest that the symbolic use of emergency in our current economic situation is yet another data point consistent with the trajectory of civic war. And yet, while the Obama administration has secured vast powers over huge American corporations, the opposition has continued in its vigorous appeal to the people (or, what Meyers calls the "publicizing" of a political contest). At least for the moment, the ubiquitous deployment of emergency in the cases of the economy, health care, and the environment has left the opposition neither docile nor speechless. Perhaps in the culture of emergency, not all emergencies are the same. In identifying a source of renovation, Civic War and the Corruption of the Citizen could be read as an advice-forthe-citizen book. Instead of providing a civic education in formal procedures, it urges citizens to exercise judgment and stand in opposition. However significant that advice may be, Meyers's focus on the complicity of citizens in the culture of emergency suggests that we (as citizens) get the government we deserve. That we can choose to act in the public sphere is certainly true. That ordinary citizens are complicit in the Bush administration's actions is a tougher sell, particularly in a crowded, complex, national political environment in which not only the other branches of government but also the media, the military, the bureaucracy, 50 states, corporations, and highly organized interest groups vie for attention. The citizen's position requires not merely judgment but information and the wherewithal to be heard. While the position of the citizen tells us something about executive overreach, it may not provide the widest vantage point for understanding our present circumstances or how to remedy them.


Prospects of use of not stir up microwave electromagnetic radiation for diagnostics and research of plasma and neutral gas environments are considered. Are analyzed physics of processes and possible techniques of the organization of diagnostics and monitoring of change of a condition of gas environments with use of open cylindrical resonators.


A reliable determination of the isospin breaking double qua rk mass ratio from precise experimental data onη → 3π decays should be based on the chiral expansion of the amplitu de s pplemented with a Khuri-Treiman type dispersive treatment of th e final-state interactions. We discuss an extension of this formalism which allows to estimate the e ff cts of thea0(980) and f0(980) resonances and their mixing on the η → 3π amplitudes. Matrix generalisations of the equations describing elasticππ rescattering withI = 0, 2 are introduced which accomodate both ππ/KK̄ andηπ/KK̄ coupled-channel rescattering. Isospin violation induced by the physicalK+ −K0 mass difference and by direct u− d mass difference effects are both accounted for in the dispersive integrals. Numerical solutions are constructed wh ich illustrate how the large resonance effects at 1 GeV propagate down to low energies. They remain s mall in the physical region of the decay, due to the matching constraints with the NLO chira l amplitude, but they are not negligible and go in the sense of further improving the agreement w ith experiment for the Dalitz plot parameters.


The In-segregation in 7.5-nm Ga1-x'Inx'Ny'As1-y'/GaAs single quantum well (QW) is studied theoretically. The nominal (In, N) contents in the QW are chosen to be (0.35, 0.015) and (039, 0.03) for the emission wavelengths at 1.3 and 1.55 mum, respectively. Muraki's model is used to model the composition profiles in the QWs. In-plane strain, confinement potential, and sub band energy levels of the QW are calculated using multi-band effective mass theory. Our results show that the optical transition energies are approximately constant for the segregation efficiencies smaller than 0.7 in both QWs


We all are passing through Big Data Renaissance right now. Academic literature shows increasing interest to subject of application of Big Data technology to cross-sectoral business and relevant scientific research. But portion of research papers devoted to application of Big Data to Taxation is relatively small, despite of the fact that tax generates huge amounts of Data and has enormous potential to benefit from Big Data Analytics. This paper is a conceptual approach to build theoretical and methodological foundation for Data Analytics application in taxation. It is described how tax authorities can benefit from their operational data. Primary prerequisites for efficient application of Advanced Data Analytics are revealed.


Abstract In Korea the consumption of coffee has been continuously increased last 10 years. During the period the market size and the numbers of the coffee shop also has been expanded dramatically. The purpose of this study was to examine whether the consumer's selection attributes of coffee shop affect the revisit intention of coffee shop and the brand trust had moderating effects between consumption attributes and revisit intention. Also it was analyzed whether there were statistic differences according to the demographic characteristics. For this study the survey was conducted on Seoul City and Kyeongki-do province and 600 questionnaires were distributed and 480 were collected and 470 samples were analyzed. The results of this study were as follows. All the factors of the consumer's consumption attributes of coffee shop had affected the revisit intention. And the factors of brand trust had moderating effects on revisit intention. There were statistic difference by gender for the additional services and there were also statistic difference according to the age group for the new technology environmental service of the inside of coffee shop. The implications of this study were the selection attributes of coffee shop were diverse and the brand trust were considered significant and the consumer's preferences were different according demographic characteristics such as gender, age, and incomes.


The digitalization of health care work began gaining momentum in the 1990s in Europe and the United States. Since then social studies of information and communication technology (ICT) have taken a substantial interest in health care organizations as sites of investigation. Often based on detailed ethnographies of technology usage and clinical work, sociological and anthropological studies of ICT point to the local and contingent nature of standardized technologies and procedures in health care institutions. One of the conclusions is that to understand technological and procedural standardization – or attempts to standardize – it is crucial to be attentive to dynamic and complex interplays between ICT and its social environment.

At present, it is most important part in the next tax reform of China to unify the foreign and domestic corporation income taxation (CIT). The paper aims to study the changes of the status of CIT and its actual tax burden for different kind of firms, collecting a lot of relevant data and analyzing from three aspects as follows: that is the ratio of the CIT to total tax revenue, the structure of the CIT; and the tax burden of the CIT. The paper analyzes not only the macro-tax burden, the changes of the taxation level and its structure, but the micro-tax burden of CIT, the differences in the tax burden of domestic and foreign enterprises as well. Finally, the paper set out some proposals in the design of the tax rates and tax burden of the CIT of China.


EmergenCy management personnel at federal, stale, and local levels can benefit from the increased situational awareness and operational efficiency afforded by simulation and modeling for emergency preparedness, including planning, training and exercises. To support this goal, the Department of Homeland Security's Science & Technology Directorate is funding the Integrated Modeling, Mapping, and Simulation (IMMS) program to create an integrating framework that brings together diverse models for use by the emergency response community. SUMMIT, one piece of the IMMS program, is the initial software framework that connects users such as emergency planners and exercise developers with modeling resources, bridging the gap in expertise and technical skills between these two communities. SUMMIT was recently deployed to support exercise planning for National Level Exercise 2010. Threat, casualty. infrastructure, and medical surge models were combined within SUMMIT to estimate health care resource requirements for the exercise ground truth.

Electrical distribution system is crucial in electric power system because it is directly related to customers and power utilities. Reliability is essential in an electric power system that can be defined as supplying power to the system according to customer satisfaction. Distributed Generation (DG) provides on-site services for customers and supports the distribution network. In this research, different reliability tests have been carried out based on various reliability indices. Through different reliability tests, optimum location to install DG in distribution system is found out. Here introducing installation of single DG at optimum location has more positive impact than installation of multiple DGs in the same feeder at different locations on distribution system reliability. To evaluate the reliability indices Roy Billinton test system is used and modeled using Electrical Transient Analyzer Program (ETAP).


Patients with mitochondrial disease often present with prominent neurologic symptoms; the alteration of mitochondrial metabolism produces an excess of ROS and cytokines that appeared implicated in the activation of microglia; similar considerations apply to Amyotrophic Latera Sclerosis (ALS) and other neurodegenerative disorders. The microglia polarization by mitochondrial metabolism modulation could be considered an option to treat the neuroinflammation and neurodegenerative disorders, similar to macrophage action in case of muscle inflammation and atrophy. Furthermore, thanks to the availability of several biomarkers including mitochondrial microRNAs it should be possible to monitor metabolic state and microglia mitochondrial metabolic shift.


The most basic positioning technology GPS cannot be used effectively due to the distortion of its signals in closed areas. Therefore, different technologies are used for positioning within these areas. Examples of these technologies include Bluetooth Low Energy (BLE), a low-power and cost-effective technology, and Ultra Wideband (UWB) technologies that have many advantages by broadcasting with short pulses at high bandwidth. In this study, indoor positioning systems were developed using BLE and UWB technologies, and security threats and location prediction performances of these systems were examined. There are differences between BLE and UWB technologies such as standard, bandwidth and distance estimation algorithms. Because of these differences, the security threats related to these two technologies differ. In this context, security problems that may arise depending on the technology used in the system are mentioned. In addition, the performance of these systems developed using these two different technologies, was compared by conducting distance and positioning tests in the same area with an area of 12m x 15m. In the tests conducted to compare the positioning performance from these tests, it was calculated that the UWB indoor positioning system had a positioning error of 0.43 m and the BLE indoor positioning system had a positioning error of 1.54 m in the same environment.


Objective To analyse the epidemiological data on cases of malaria reported from 2004to July 2013in order to provide evidence of malaria elimination in China. Methods Epidemiological data on cases of malaria reported via a national web-based direct reporting system and annual statistics on malaria according to a national study of malaria control were collected from 2004to July 2013and analyzed using Microsoft Excel 2010. Results In total,241 430cases of malaria were reported in 31provinces/municipalities/autonomous regions(P/M/A)according to the national web-based direct reporting system.Vivax malaria accounted for 76.54%of these cases,falciparum malaria accounted for 8.33%,and unclassified malaria accounted for 15.13%.The cases mainly involved young men and were concentrated in Anhui(45.16%),Yunnan(22.26%),Hainan(9.68%),Henan(8.16%),and Hubei(4.28%)provinces.Of the total cases, 33.02% were clinically diagnosed while the remaining 66.98% were definitively diagnosed.There were 235deaths due to malaria,87.66%of which involved falciparum malaria.According to nationally reported statistics on malaria from 2004-2012,81.18%of cases(204 613cases)were autochthonous while 18.82%(47,439cases)were imported.From January to July 2013,there were 2 987cases of malaria according to the national web-based direct reporting system;0.87% of these malaria cases were clinically diagnosed and 74.89% were cases of falciparum malaria.Only 34of these malaria cases were autochthonous. Conclusion The prevalence of malaria has been significantly reduced in China,but the substantial increase in imported malaria poses a challenge.


In this thesis, the geodynamic evolution of the Piemonte-Ligurian ocean is investigated
by means ofcombined structural and petrological methods. It aims to assess the
most important processes involved in [I] incipient oceanic rifting and opening of the
basin, and [2] subduction of oceanic lithosphere. The conclusions drawn from this
study primarily apply to the situation in the Piemonte-Ligurian ocean, and the
dynamics of orogeny in the Alps and Apennines. However, strong analogies exist between the Piemonte-Ligurian ophiolites and oceanic lithosphere exposed in presentday
oceanic rifts (Le Red Sea), along margins of slow-spreading "Atlantic-type"
oceans, and in marginal basins (Sea of Japan, Tyrrhenian Sea, Cayman basin). Since
the development of these basins is a topic ofdebate (e.g. Moores 1982; Bonani 1988;
Jolivet et al. 1989; Tatsumi et al. 1989), it is suggested that the processes, inferred here
for the case of the Piemonte Ligurian ocean, may also playa role in the geodynamic
evolution of these modem basins.
The data underlying this thesis are derived from a number of ophiolite complexes
exposed in the Ligurian Alps and Apennines (Fig. 1.1, 1.2). In this region, a sequence
oflow-grade (prehnite-purnpellyite facies) to high-pressure low-temperature (eclogite
facies) metamorphic ophiolites and related sediments allows a study of the structural
and metamorphic evolution ofoceanic lithosphere in a subduction zone which evolved
into a zone of continental collision. In addition, a structural study of the low-grade
ophiolites in the Apennines (Bracco Massif) and of a large body of mantle peridotites
in the Ligurian Alps (Erro-Tobbio peridotites in the Voltri Massif) enables the
identificationof the main processes during incipient oceanic rifting and opening ofthe
Piemonte-Ligurian ocean


Strains induced in the skeleton by functional activity are critical to the homeostasis of bone tissue. An in vivo model of disues osteopenia was used to examine whether the removal of these regulatory stimuli induces a uniform loss of crotical bone through the whole organ or whether the loss of bone is focused at specific sites of the cortex. The right radii of five adult male turkeys were isolated from their normal functional loading for 8 weeks. The corresponding left radius from each animal served as an intact contralateral control. An additional group of five turkeys was used as time‐zero controls to assess the initial areal symmetry of the left and right radii. Areal properties were assessed at three sites at equal intervals spanning the middle 3 cm of the diaphysis. Adaptation was determined for each cross section as a whole, as well as specifically by site by division of each cross section into 12 equal angle sectors. The average across all experimental sections after 8 weeks of disuse was 12.1 ± 1.9% (± SE) loss of bone mass. The change in mean cross‐sectional area varied little between the three diaphyseal sites (−10.2 ± 3.3%, −13.5 ± 3.8%, and −12.6 ± 4.0%) and occurred primarily (84%) by uniform expansion of the endosteal envelope. However, elevated intracortical porosity following 8 weeks of disuse was highly nonuniform, with 58% of the increased porosity preferentially located in the ventral/caudal cortex (representing only 25% of the cortical area). From these data, it is concluded that bone responds to the removal of functional stimuli with a uniform, organ‐wide loss of mass, yet intracortical remodeling occurs preferentially within specific areas of the cortex. The lack of spatial coupling between these events suggests that the two processes may be governed by distinct physiologic criteria.


Overall the author acknowledges that the current publication is the slightly reworked text of his doctoral thesis (rear cover) and it is the lack of surgical editing that is likely to make the publication less accessible to the general reader. For example, the copious footnotes, so essential for a doctorate thesis, are too detailed for all but the most specialist reader. I suggest that, where appropriate, they should have been edited into the text or omitted. Similarly the numerical paragraph headings and sub-headings are a distraction and would benefit from editing out. This publication reflects the significant contribution this author has made and continues to make to the discourses on social professional work in the UK. I suspect it is too specialist to be purchased and read by, for example, social work students or even by many social work academics. It catalogues discussions on the potential of social pedagogy published in the English language over the past 25 years and should find a place in academic libraries where it can be referred to as an important historical document. I recommend that the reader does not follow the prescription of the King in Alice in Wonderland and 'begin at the beginning and go on till you come to the end: then stop'. This is a text that scholars may wish to revisit as they mine the rich and detailed evidence collected together appraised and evaluated by the author, an important reference book rather than one to be read from cover to cover. For the more general reader, the bibliography contains an extensive list of Kornbeck's previous publication. I recommend readers who are unfamiliar with his work 'begin at the beginning' with The diversity of social pedagogy in Europe (2009). There remains the issue of Europeanisation, which Kornbeck addresses as a specific research question. Given the present crises across Europe I am not surprised that the author is at best tentative in his conclusions. He acknowledges the increase in Euroscepticism, which is evident across a much greater geopolitical area than the UK, which continues to be ambivalent on many, if not most European issues. The evidence in each of the case studies leads the author to affirm the primacy of the nation state. While German ideas and practice influenced developments in Denmark, and practices in Denmark impacted on some policy initiatives in England under New Labour, in the final analysis it appears that each country, reflecting their dominant political ideas and institutions, tends to do things in their own way.


Abstract Several well-known generalizations of the usual topological To-axiom to topological categories are compared. It is shown that they lead to two different concepts: To and separatedness. The resulting sub-categories are characterized for some important categories of convergence spaces. They provide natural examples disproving the equivalence of the two concepts. Necessary and sufficient conditions are given for the To-objects and separated objects to coincide.


The purpose of this article is to present and describe the general characteristics of the existing programs in Mexico related to sustainable housing as well as one related to sustainable urban development. The features of National Programs such as Green Mortgage, DUIS and programs of international nature adopted and coordinated by Mexican institutions financially and technically supported by international organisms such as NAMAs and MDL are described. Such arrangements act like funding strands to develop and acquire housing that uses technology focused on the conservation and usability of natural resources. Finally, the depiction and analysis of the plans before mentioned where they only refer to the heating and energetic aspects but not to a real sustainable approach, that is to say the reflection on the economic, social and environmental factors implicated in the planning, design, and construction of housing is presented. This in spite of the lecture of sustainable housing being considered of daily use by the government authorities responsible for housing (INFONAVIT, FOVISSSTE, SEDATU, CONAVI, etc.) together with the existence of programs intended for that purpose ("Esta es tu casa" Program, Green Mortgage, "Vida integral INFONAVIT": Sustainable Housing, ECOCASA Program y Sustainable Integral Urban Development (DUIS).

We have designed coupled diode resonators to study the effect of small perturbations due to weak symmetric coupling on chaotic dynamics. Our experiment clearly demonstrated that chaos of the diode resonators was suppressed so that chaotic motions were converted into periodic ones with small modifications to the attractor when an appropriate coupling signal perturbed the diode resonators. Many unstable periodic orbits were stabilized and they were very stable depending on the dynamical properties of the coupling signals. Our results suggest that coupling of signals belonging to the same class is effective in controlling chaos.

Scientific workflows are data and compute intensive thus may run for days or even for weeks on parallel and distributed infrastructures such as HPC systems and cloud. In HPC environment the number of failures that can arise during scientific workflow enactment can be high so the use of fault tolerance techniques is unavoidable. The most frequently used fault tolerance techniques are job replication and checkpointing. While job replication is based on the assumption that the probability of single failures is much higher than of simultaneous failures, the checkpointing saves certain states and the execution can be restarted from that point later on. The effectiveness of the checkpointing method depends on the checkpointing interval. Common technique is to dynamically adapt the checkpointing interval. In this work we give a brief overview of the different checkpointing techniques and propose a new provenance based dynamic checkpointing method.


The activity of prediction,which scientifically discovers the close relationship between the future and human destiny, is the foundation of the modern human activity.In the following article ,on the basis of forming development on the system of prediction through history, the writer probes into the forming of modern system of prediction,which plays an important role in leadership structure, and into the nation prediction system, which leads to the national security in some way. Just because countries set up the perfect prediction system day by day, the modern international political relation have been formed and settled down.The modern system of prediction is moving towards the development of social system. All decisions of organizations in modern society depend on the prediction system day by day. The reform of social system is the cord of new style for behavior of the system of prediction.


[Objective]To discuss the risk and precaution of the treatment of intertrochanteric fracture in elderly patients.[Method]The treatment of 42 patients with intertrochanteric fracture treated from Aug. 2001 to Dec. 2004 were analyzed. There were 22 males and 20 females aging from 70 to 95 years with an average of 78 years. According to Evans classification system for intertrochanteric fracture,7 cases were type I, 19 cases type II, 12 cases type III, 4 cases type IV. Thirty patients suffered from medical illness of cardiovascular, respiratory, endocrine-metablolic, digestive, nervous preoperatively. Fifteen cases were found to have two kinds or more of diseases. [Result]The interval between admission and operative treatment was from 7 to 22 days , with the average of 13 days. There were 9 complications after operation: pulmonary infection in 5 cases, hypoglycemia in 1 case, deep venous thrombosis in lower extremity in 5 cases, heart failure in 1 case; 4 patients were found to have two kinds or more of complications. The rate of complications was 21.4%. The patients were followed up from 6 months to 3 years, with the average of 12 months. [Conclusion]The aged patients often suffer from one or more illness, the risk is not from operation but from the medical illness. After enough preparation of perioperative period before operation, the operation should be taken much more early. It doesn't need to pay attention to anatomic reduction, but to reducing the time of operation and anaesthesia, reducing bleeding, and reducing the interfere to patient by the operation and anaesthesia.


The article presents the results of experiments obtained in stationary experiments on the basis of grain-fallow and grain-grass crop rotations on meadow-chernozem soil in the Omsk region. The influence of spring wheat precursors (alfalfa of the 3rd year of life and fallow) on individual elements of soil fertility and crop yield has been established. It was revealed that when cultivating spring wheat by fallow in the grain-fallow crop rotation, the nitrogen balance (-28 kg/ha) is negative with an intensity of 66 %. When sowing wheat in grain-grass crop rotation on a layer of perennial grasses, the nitrogen balance is positive (+21.0 kg/ha) and the intensity is 119 %. The favorable effect of the legume component in the crop rotation on the nitrogen regime of the soil significantly increased the yield of spring wheat by 0.5 t/ha in comparison with wheat cultivated in the field crop rotation by bare fallow. Under similar conditions, studies were carried out on irrigated meadowchernozem soil in an eight-field stationary grain-grass crop rotation. The removal of nitrogen by the yield of various perennial grasses, as well as the responsiveness of alfalfa, bromus and sweet clover with productivity parameters to the level of nitrogenphosphorus nutrition, were studied. The current mobilization of nitrogen under these conditions under the vegetative brome without fertilizers was 76 kg/ha. When optimizing the phosphate regime of the soil, this indicator increased to 99 kg/ha.  The removal of nitrogen by alfalfa on similar agricultural backgrounds increases due to symbiotically fixed nitrogen, by 89 and 193 kg/ha, respectively, or 2.2 and 2.9 times. Alfalfa and sweet clover responded positively to the improvement of mineral fertilizing conditions (P60N60-160). In alfalfa of the 1-5 year of life the collection of green mass and fodder units increased to 40.56 and 7.00 t/ha, respectively, or by 86 and 54 % relative to the control without fertilizers, with 82.76 GJ of exchange energy per hectare. The productivity of sweet clover of the 2nd year of life increased up to 30.85 t/ha of green mass and 2.83 t/ha of fodder units or by 37 and 17 % relative to the control.


L. DOCHERTY, M.R. ADAMS, P. PATEL AND J. McFADDEN. 1996. A rapid and sensitive technique, based on the magnetic immuno‐polymerase chain reaction assay (MIPA), was developed for the detection of Campylobacter jejuni in milk and chicken products. Target bacteria are captured from the food sample by magnetic particles coated with a specific antibody and the bound bacteria then lysed and subjected to PCR. The MIPA could detect 420 cfu g‐1of chicken after 18 h, 42 cfu g‐1after 24 h, and 4.2 cfu g‐1after 36 h enrichment. For artificially contaminated milk 63 cfu ml‐1could be detected after 18 and 24 h and 6.3 cfu ml‐1after 36 h enrichment.

The article describes the ongoing impact biomechanics research programme currently being supported by the Commission of the European Communities. The six principal research themes are listed, as is the background history and the reasoning leading up to the start of the programme in late 1978. The projects are briefly described, in terms of gaps in knowledge detected, research methodology, and expected results.


Capacitive power transfer (CPT) is an alternative method for wireless power transfer (WPT) which has started to draw wide attention. Compensation topologies play significant role in improving the power transfer performance of a CPT system, so many different topologies have been proposed and investigated. This paper presents a comparative study of six compensation networks, namely single L, double-sided LC, LCL, LCLC, CLLC, and LCLC-LC for CPT systems. Based on the first five topologies that are already utilized in CPT systems, a new LCLC-LC topology is investigated in this research. The advantages and disadvantages of these compensation topologies are summarized by analyzing their equivalent circuit models, power transfer characteristics against the load, coupling, and frequency variations. It has found if the series equivalent resistances are ignored, all these five topologies can be designed to achieve constant voltage or constant current output against load variations under fully tuned conditions. However, their output power changes with coupling variation. The steady state analysis of the impedance transformation and voltage or current source characteristics has shown that the double-sided LC topology can be tuned to achieve a constant output voltage against both coupling and load variations.


Poor college students' serious inferiority complex not only affects their mental health but also affects social harmony and development.Therefore,pay attention to the poor college students' inferiority has important significance.The present study of inferiority on poor college students mainly focus on its performance,influence,causes and adjustment measures.Most studies are more qualitative research,less quantitative research,more experience summary research,less theoretical research,more repeated research,less innovation research.A Dialectical View should be used when study the influence of inferiority complex.Future research should strengthen qualitative research and theoretical research,take the innovation into account.


In this paper, we propose the scheme solving privacy infringement in RFID systems with improving the scalability of back-end server. With RFID/USN becoming important subject, many approaches have been proposed and applied. However, limits of RFID, low computation power and storage, make the protection of privacy difficult. The Hash Chain scheme has been known as one guaranteeing forward security, confidentiality and indistinguishability. In spite of that, it is a problem that requires much of computation to identify tags in Back-End server. In this paper, we introduce an efficient key search method, the Hellman Method, to reduce computing complexity in Back-End server. Hellman Method algorism progresses pre-computation and (re)search. In this paper, after applying Hellman Method to Hash chain theory, We compared Preservation and key reference to analyze and apply to parallel With guaranteeing requistes of security for existing privacy protecting Comparing key reference reduced computation time of server to reduce computation complex from O(m) to than the existing form.


Trap conditions at shallow subbottom depths are important and decisive to seismic reflection of shallow gas.Based on analysis of the trap conditions,we conclude that there are two kinds of traps normally:lithologic trap and fault trap.According to the seismic reflection features of shallow gas,subbottom sediment,and shallow faults in the western South Yellow Sea,we conclude that:(1)The traps of shallow gas at the shallow depths are mainly controlled by the bottom sediment and shallow faults,and the traps are usually lithologic and fault ones.(2)The bottom sediment is normally important and decisive to the seismic reflection features of shallow gas.(3)Under the actions of tidal current,river and ocean,bottom sediments in modern deltas are greatly different from the shallow strata beneath them.As the sediments of modern delta have thick muddy silt and silty muddy layers,their trap ability is strong,and they can trap enough shallow gas to form large scale of acoustic blanket,but projecting flag shape at its top boundary is often observed.(4)Shallow faults can form fault trap,and also can be the passway for shallow gas to migrate upward.(5)If mud cencenrtation is high in some strata,shallow gas will be trapped several times,and reflection boundary and acoustic turbidity showed as stairs can be observed.


Abstract: A series of phosphinyl-, phosphonyl- and phosphorylacetates was hydrolyzed in the presence of Pig Liver Esterase (PLE) to give the corresponding P-chiral phosphoroacetic acids and unreacted esters in a high enantiomeric purity (up to 100% ee).


The non-linear finite element equilibrium equation based on the contact interface is build by the finite element method of sub-structure using cohesion degree of freedom,contact constraint which is dealt with by the augmented Lagrangian multiplier method,and pile-soil interaction effect was calculated by nonlinear numerical calculation.Results show that the general trend of numerical results and the measured results are the same.The introduction of the contact problem can reasonably explain the mechanism of pile-soil interaction effect.


Of 290 children with an initial febrile convulsion, 216 met Livingston's criteria for a "simple" febrile convulsion and 74 for "epilepsy triggered by fever." Daily phenobarbital produced a significant decrease in febrile seizure recurrences in both groups, as compared to children who received phenobarbital at the onset of fever and those who received no phenobarbital prophylaxis. Although statistically significant in both groups, the effectiveness of daily phenobarbital was more pronounced in the "epilepsy with fever" children.


Case Report Vitamin A is essential for normal retinal function and it plays an important role in corneal and conjunctival epithelial cell. Vitamin A deficiency has been known to occur as a result of poor dietary intake, chronic liver diseases and gastrointestinal malabsorption. Here we report 30 years old male with history of chronic diarrhea and fatty liver presenting as bilateral corneal ulcer with Bitot spots and conjunctival xerosis with decreased macular thickness on optical coherence tomography (OCT)


The effect of the laser shock processing(LSP) on the vibration fatigue property of the titanium alloy TC6 was investigated. The results show that the large residual compressive stress field is formed on the alloy surface by LSP technology, and the nanocrystalline appears on the alloy surface, which improves the fatigue resistance property of the alloy obviously.


Differential Evolution (DE) is a simple, powerful and easy to use global optimization algorithm. DE has been studied in detail by many researchers in the past years. In DE algorithm trial vector generation strategies have a significant influence on its performance. This research studies that whether performance of DE algorithm can be improved by incorporating selection advancement in effective trial vector generation strategies. A novel advancement in DE trial vector generation strategies is proposed in this research to speeds up the convergence speed of DE algorithm. The proposed fitness proportion based random vector selection DE (FPRVDE) is based on the proportion of individual fitness mechanism. FPRVDE reduces the role of poor performing individuals to enhance it performance capability of DE algorithm. To form a trial vector using FPRVDE, individual based on the proportion of their fitness are selected. FPRVDE mechanism is applied to most commonly used set of DE variants. A comprehensive set of multidimensional function optimization problems is used to access the performance of FPRVDE. Experimental result shows that proposed approach accelerates DE algorithm.


A rare clinical presentation arterial Thoracic outlet syndrome (TOS) is described in a young school-girl. TOS causing distal; disease is a rare cause of artery to- artery embolic stroke. Brain-stem ischemic stroke is a result of compromise to the posterior circulation. This is often due to antegrade embolism from the heart or proximal vessels. Retrograde blood flow has been described in the subclavian artery, thus making the distal subclavian artery a source of possible retrograde embolism to carotid circulation1. Clinical presentation also included left hemiparesis caused by right subclavian artery thrombosis and retrograde embolizatoin of thrombus via common carotid artery to the right middle cerebral artery (MCA) distribution.

Plus material of antistatic wool-polyester fancy suiting were prepared using the excellent characteristics of conductive fibers.The raw material selections,production processing and possible actions were analyzed.The results indicated that when keeping the proportion of wool and polyester 70 percent and 28 percent separately,and the dosage of conductive fibers between 1% and 3%,it not only acheieved the antistatic effect,but also kept the suiting owing the stylistic features.In the process,controlling single twist multiplier and doubled twist multiplier 95 and 140,respectively,meanwhile,adopting the bicirculating vacuum yarn steam process which firstly setting at 90 ℃ in 15 min and then at 88 ℃ in 10 min,plus material can not only have the characters of traditional fancy suiting note soft and smooth,but also can show best properties of antistatic and pilling resistance which can achieved 4~5 level.


2-Substituted 7-oxo-7,11b-dihydrodibenzochromenilium derivatives (1-ArPyl(+)s) undergo reversible changes in near-infrared absorption when Ar = ferrocenyl, and complete on-off switching of luminescence when Ar = p-tolyl, m-tolyl, or phenyl, by the reaction with methanol or methoxide ion and with acid.


Sidestep is developed by BROHA.The purpose is to estimate the capacity of body to adjust and recover from maximal exercise load.The result shows that the sidestep index is not highly correlated with maximal oxygen uptake,thus cannot give a very precise estimate of cardiovascular fitness.Secondly,sidestep index can only make evaluation on good or poor condition for subjects,cannot give a accurate evaluation.Thirdly,sidestep index cannot reflect the age and gender related changing of maximal oxygen uptake and cardiac output.Based on above situation,much more research should be made before sidestep test become a valuable measurement of cardiovascular fitness.

This study presents the findings of an assessment of the ground water quality for drinking purposes using Water Quality Index (WQI). To ascertain the water quality, detailed physical and chemical analysis of water samples was carried out on samples. Samples from twelve (12) sampling points were taken and analysis was carried out on several parameters such as pH, Temperature, Electrical Conductivity (EC), total dissolved solids (TDS), Sodium, Potassium, Calcium, Fluoride, Chloride, Bicarbonates, Nitrate, Sulphate, Magnesium, Iron. Analysed parameters were compared with the World Health Organisation (WHO). It was observed that most of the water sample parameters conformed to the standards for Drinking water. The Water Quality Index values obtained ranged from 36.32 to 113.11, signifying a water quality class ranging from excellent to poor water quality. From the classification of the samples, five (5) samples indicating about 41.67% of the total water sample was classed as having "excellent" water quality (WQI < 50), Six (6) samples representing about 50.00% of the total water sample showed "good" water quality (WQI 50-100) and one (1) which is 8.33% as having "poor" water quality (WQI>100). The low values of WQI in the water samples indicate that water obtained from this area is suitable for drinking with little or no treatment.


To analyze the binding of cytotoxic T lymphocyte epitope candidates derived from HPV16E7to the HLA-A2molecule and the possibility of them being HLA-A2-restricted CTL epitopes,the molecular mimicry of CTL epitope candidates bound to the HLA-A2molecules and of the HLA-A2-peptide complex was established by a computer molecular modeling.The results showed that the three-dimensional configurations of HLA-A2binding peptides were compatible with those of HLA-A2-restricted CTL epitopes and they could bind to HLA-A2molecules quite well.According to mole cular modeling,it is suggested that the predicted peptides may be the CTL epitopes restricted by HLA-A2molecules,and can be useful in the study of syn-thesis,screening,identification and preparing peptide vaccine.

It should be practiced only where it is indicated like rigid perineum, any instrumental delivery and


This article discusses the most significant aspects of DTT's evolution in Spain since the analogue switch-off in April 2010. It underscores the severe cutbacks affecting public service television broadcasters and their impact, as well as a return to government control over the Spanish Broadcasting Corporation (RTVE) in particular. It also emphasizes the major tendency towards concentration in the national private DTT market and the inviability of most regional and local broadcasters. All of these issues are analysed from the perspective of their worrying impact on pluralism.


Exchange rate dynamics has been a persistent factor affecting capital accumulation in developing economies especially in the area of capital inflows which measures the rate of movement of capital into an economy as it concerns its international consumption-investment relation with other economies. However, there are many factors that affect the rate of capital inflows and outflows into and out of a given economy. This work examines the impact of exchange rate fluctuations on capital inflows in Nigeria from 1970-2010. Using the generalized autoregressive conditional heteroscedasticity (GARCH) model, results obtained indicate that the impact of exchange rate fluctuations on capital movement into Nigeria economy at this period is not so intense as that of  its trade openness. The study therefore, recommends that trade openness policies should be formulated and implemented such that they would induce maximum capital inflows needed for economic growth. Key words: Capital,  Inflows,  Exchange rate, Volatility, and Inflation


Marxist property rights theory and western property rights theory are fundamentally different in their ideological systems,one is historical materialism and the other is historical idealism.Combining with the stateowned enterprise stock system reform,this paper compares these two property rights theories with emphasis on the basic points of Maxisim property right theory.


After a brief discussion of data analysis methods, this paper reviews new results and open questions on the structure of the quiet corona. The formation of the helium spectrum is discussed, and some of the frac-tionation processes that can lead to helium abundance variations in the outer solar atmosphere are described. It is suggested that the helium abundance in those layers where the prominent helium lines are formed depends on the magnetic topology of the over-lying corona. If helium is more abundant in closed than in open regions, a number of unsolved problems with the helium spectrum can be explained. Then a discussion follows if, and where, convection might play a role in stellar coronae and winds. The nal part of the paper focuses on problems related to the slow solar wind in the ecliptic: its formation region on the Sun, its properties within the main acceleration zone as inferred from coronagraph and radio observations , and its impact on the interstellar plasma.


ABSTRACT Multimodality has been a growing research interest in the field of applied linguistics. With the actor-network theory as an analytic framework, the purpose of the present study was to explore how university students of Teaching English as a Foreign Language (TEFL) take advantage of both material and non-material semiotic resources while being involved in the process of developing classroom activities. Furthermore, the semiotic resources of these students including their language, gaze, and gesture were analyzed using systemic functional multimodal discourse analysis (SF-MDA). To do this, using an ethnomethodology, we videotaped the interaction of a group of 6 TEFL students developing materials, for the improvement of learners' intercultural competence, on the topic of food. The findings indicated that the participants developed these materials as they interacted with each other, as human semiotic resources, as well as their digital tools, as non-human resources. In addition, while mainly expressing their mental processes, they also conveyed positive attitudes and built negotiation expanding space using their gesture with both fast and slow graduation. Their gaze was also engaged, directed at both the group members and objects developing the classroom activities.


Abstract In this paper, we consider the weighted composite quantile regression for the linear model when the data are right censored and the censoring indicators are missing at random. The adaptive penalized procedures are proposed to discuss variable selection in the model. Under appropriate assumptions, the asymptotic normality and oracle property of these estimators are also established. The simulation studies are conducted to illustrate the finite sample performance of the proposed methods.


We consider approximate dynamic programming for the infinite-horizon stationary $\gamma$-discounted optimal control problem formalized by Markov Decision Processes. While in the exact case it is known that there always exists an optimal policy that is stationary, we show that when using value function approximation, looking for a non-stationary policy may lead to a better performance guarantee. We define a non-stationary variant of MPI that unifies a broad family of approximate DP algorithms of the literature. For this algorithm we provide an error propagation analysis in the form of a performance bound of the resulting policies that can improve the usual performance bound by a factor $O\left(1-\gamma\right)$, which is significant when the discount factor $\gamma$ is close to 1. Doing so, our approach unifies recent results for Value and Policy Iteration. Furthermore, we show, by constructing a specific deterministic MDP, that our performance guarantee is tight.


Height, hypocotyl length, epicotyl length and cotyledon number were investigated in juvenile seedlings of its seed orchard and seed stand treated by harvesting residues (neddle, branch and bark) of Brutian Pine (Pinus brutia Ten.). Averages of height, hypocotyl length, epicotyl length and cotyledon number in juvenile seedlings were 8.03 cm, 1.33 cm, 6.70 cm and 8, respectively, while there were large differences between seed sources and among treatments. Results of analysis of variance showed statistically significant (p<0.05) differences between seed sources and among treatments for the characteristics except for epicotyl length. Positive and significant (p<0.05) relations were generally found among the characteristics based on the results of correlation analysis. Branch treatment showed higher growth performance for seedling height than other treatments in both seed sources.


The technique of 210Pb dating of sediments over time scales of up to 120 years is described and illustrated by a study of Lake Tali Karng. Results from the study of a sediment core from the deepest part of the lake shows that the flux of unsupported 210Pb to the sediment is about 145 mBq cm-2 year-1. Over the last 100 years, about 75 cm of sediment has accumulated at an average rate of 150-200 mg cm-2 year-1. Calculations using two models to convert 210Pb activity-depth profiles to age-depth profiles indicate that the sedimentation rate has increased slightly over the last 100 years. It is estimated that about 14% of the 210Pb falling in the catchment reaches the lake sediment, but depending on the assumptions made the possible range is 7-60%.


Faced by centralizing governments which have mobilized parental support, the professional responsibilities which once characterized the professional status of teachers are being eroded. Curriculum content is now the responsibilty of central government. So too is pupil assessment, initial and in-service training. Teaching method and school management are following rapidly. Even local management by local education authorities is threatened with elimination. In this volume 12 leading experts analyze the recent history of the teaching profession in Britain, consider the future scenario and suggest ways to which teacher professionalism can reassert itself before it is too late.


Yesterday, Darren Draper put out a post expressing some concerns with Teachers Pay Teachers. Shortly after putting out that post, Darren was forced to don


Pulmonary function tests were performed before and at different times after 250 mg L-Dopa in 12 patients with Parkinson's disease (PD). Six were de-novo patients, the other six patients had been taking L-Dopa over different periods. All patients had an abnormal basal flow-volume loop, which significantly improved only in de-novo patients. This improvement occurred early and was independent on improvement of neurological symptoms. The effect of L-Dopa on pulmonary function could be a useful test in differentiating PD from related extrapyramidal syndromes.


We discuss the structure of the dressed fermion propagator in unquenched QED3 based on spectral function of photon.In this approximation infrared divergences that appeared in quenched case turns out to be soft.The dimension full coupling constant naturally appears as an infrared mass scale in this case.We find the reliable results for the effects of vacuum polarization for the dressed fermion propagator.The lowest order fermion spectral function has logarithmically divergent Coulomb energy as well as self-energy,whch plays the role of confinement and dynamical mass generation.In our model finiteness condition of vacuum expectation value is equivalent to choose the scale of physical mass which is expected in the 1/N approximation.


In a growing economy the cash flows from investment projects can be expected to be rising over time. In this paper we explore the interactions of growth and uncertainty of cash flows with variable capital intensity in the decision to invest. We derive simple replacements for the usual neoclassical optimal investment rules based on IRR or NPV. We show that the ability to vary capital intensity raises the specter of perverse responses of investment to interest rates. Variable capital intensity is a sufficient condition for the perverse responses that can occur when growth rates are high or uncertainty is high. An empirical analysis of a panel data set on residential investment in the 1980sconfirms the predictions of the model and finds that about 40% of the observations fall in the positive response region.


The application of phased arrays in information measuring systems, ground stations of satellite communication systems, capable of working with multiple satellite repeaters are the different heights of the orbits and the characteristics of the information exchange. The synthesis problem is described with reference to the antenna array of rectangular waveguides with elliptical polarization. The possibility of simultaneous management of multiple antenna array pattern total phase-difference monopulse system operating in noisy environments. It is shown that the proposed new energy in the form of functional relations in the total power of the signal channel of the antenna array to the sum of noise and interference power in the sum and difference channels, an antenna array allows to synthesize total phase difference monopulse system with a higher quality compared to the known approach in it becomes possible to generate ing located near the main peak of the total radiation pattern.


The morphology, kinematics, and ionization state of the nuclear extended narrow-line region (ENLR) of the Seyfert 2 galaxy Mrk 573 are studied using narrow-band images of a grid of long-slit spectra. The entire ENLR is mapped spectroscopically, and velocity structure is studied. The velocity field map shows a typical galactic rotation picture with some important deviations. A simple geometric model, in accordance with the 'unified schemes', is employed to study the effects of various parameters of the observed picture. The best match is achieved when a biconical radiation field illuminates the ISM of the host galaxy that takes part in a normal galaxy rotation but also has radial motions close to the nucleus. The emission-line images reveal an ENLR elongated along the radio axis in the northwest-southeast direction, but a map of the flux ratio forbidden O III 5007/(H-alpha + forbidden N II) shows a different structure, with the highest excitation peak offset by about 4 arcsec along the radio axis to the southeast.

The Insufficient drive of rural consumption and the lag of the rural financial development are the two forms of the issues of agriculture,rural areas and farmers which to a large extent affect the solution and breakthrough of agriculture,rural areas and farmers.The paper discusses the mutual effect mechanism of rural finance and rural consumption under the circumstances of socialist new countries from the angle of harmonized development,and makes an empirical test and analysis.At present,rural finance as a whole acts only as an assistance to sustain rural consumption,but the effect is not obvious.The paper suggests increasing farmers' income to establish the harmonized development mechanism of rural finance and rural consumption.


Dear Sir, Bezoars have been documented as rare causes of intestinal obstruction since the late 18th century [1]. Defined as indigestible masses found in the alimentary canal; they are most commonly composed of undigested food (phytobezoar) or hair (trichobezoar). Rarer are pharmacobezoar composed of medicine. Pharmacobezoars rarely form in a normal gastrointestinal tract. Concurrent findings of altered intestinal motility, lesions, such as adhesions or carcinomas, and previous surgery are known to predispose their formation [2,3].


The tumor microenvironment (TME) is a dynamic milieu comprised of various cell types and molecular complexes that eventually evolves to promote cancer cell proliferation, metastasis, and immune evasion. Myeloid cells are a key component of the TME and play key roles in initiating antitumor responses and coordinating with cells of the adaptive immune system. However, these cells are eventually hijacked by tumors and provoke local inflammation that results in chronic cancer-associated inflammation and immune escape. Extracellular adenosine (ecADO) is an immunosuppressive metabolite that is produced in tumors that binds the adenosine 2a receptor (A2aR) which is widely expressed in immune cells. Studies have shown that blocking A2aR signaling has the potential to enhance antitumor immunity by boosting T and NK cell immune responses. However, the relationship between ecADO and tumor-associated myeloid cells is less characterized. We previously reported on the antitumor activity of A2aR and CD73 blockade in preclinical models of Pten-null prostate cancer and their impact on T cell mediated responses. Here, we examine tumor-associated myeloid cell infiltration in models of castration-naïve (CNPC) and castration-resistant prostate cancer (CRPC) the impact of A2aR and CD73 blockade. Transcriptomic, flow cytometric, and immunohistochemical (IHC) profiling studies of CNPC and CRPC from conditional Pten-knockout (KO) and Pten/Trp53-double knockout (DKO) showed that tumor-infiltrating myeloid cells constituted a significant proportion of the prostate tumor microenvironment. CD11b+/Ly6G+ cells representing tumor associated neutrophils (TANs) and myeloid derived suppressor cells (MDSCs) were the most abundant immune cell type comprising 14.9% and 32.1% of the total population, and 46.5% and 69.7% of infiltrating leukocytes in in CNPC and CRPC, respectively. Furthermore, CD11b+/Ly6G+ expressed high levels of CD73. Pte-null prostate tumors were characterized with enriched adenosine signaling signatures which were greater in CRPC compared to CNPC. Treatments with the A2aR inhibitor AZD4635 alone and in combination with CD73 antibody blockade reduced adenosinergic genes as well as genes associated with TAN/MDSC immunosuppressive functions. Additionally, tumors from treated mice exhibited improved T cell mediated cytotoxicity. Together, our findings indicate that tumor associated myeloid cells are an additional source of ecADO contributing to immune suppression which can be targeted with A2aR and CD73 inhibitors.

Based on studying the development of fault and interlayer shear zone in the dam region, it is suggested that the formation of these two kinds of structures plane was controlled by tectonic and epigenetic reworking. This paper analyzes district structure characteristic and strata lithology first, discusses structure origin of the plane, and builds up its structure origin pattern. The fault structure plane belongs to the overthrust pattern on the foundation of conjugate shear outbursts, and the interlayer shear zone belongs to the surge pattern of vertical camber beam. Based on the analysis of epigenetic reworking of the structure plane, the character and state changing law of structure plane is revealed. The fault structure plane displays thickness, material type and character segmentation.


A new method was developed for the quantitative detection of complex system of SDS and non-ion surfactant OP-10.In the complex system,the concentration of the sulfonate was determined by two-phase titration method,and the concentration of the nonion surfactant was determined by spectrophotometry.Several factors such as the condition of the determination,the amount of the indicator,the amount of the inorganic salts(Na2SO4 and KCl)as well as the effect of the interactions between SDS and nonion surfactant were investigated.The results indicate that nonion surfactant OP-10 would not influence the determination of SDS,however,the determination of the nonion surfactant OP-10 was correlated significantly with the SDS.When the concentration of the SDS was within the range of 0.8~1.0g/L,the absorbance of the nonion surfactant OP-10 varied directly with its concentration.This method is simple,convenient,accurate,reliable and the two surfactants could be determined by this method.


Abstract Background Air temperature is a relevant environmental determinant of hospitalization and mortality. Less known is the prevalence of at-home thermal discomfort and its associations with health indicators. This work aimed to characterize the association between thermal discomfort and self-reported non-communicable chronic diseases in adults living in the municipality of Lisbon. Methods Observational cross-sectional study with data collected through individual telephone interviews, with a non-probabilistic stratified (by gender, age, education, and area of residence) sample. Logistic regression models were used to estimate effect sizes, controlling for age, gender, educational level, and morbidity indicators. Results Overall, 855 adults (25+ years old) living in the municipality of Lisbon participated in the study. Only respondents who reported to be 10+ hours per day at home were included in the analysis. The sample was balanced for genders (55,2% female), with an average age of 53,4 years (SD = 17,0; maximum age=93 years old), and 40,2% (n = 356) not having a higher-level education. About three-quarters (74,2%; n = 552) reported feeling thermal discomfort at home and 56,9% (n = 414) reported having at least one non-communicable disease diagnosed. When considering the sample's most prevalent self-reported chronic diseases, a significant association with thermal discomfort was found for asthma and hypercholesterolemia (chi-square=4,08; p=.004; and chi-square=4,87; p=.027, respectively). After adjusting for sex, age, educational level, area of residence, and other self-reported morbidities, asthma was found as a significant predictor of thermal discomfort (OR = 3,03; 95% CI: 1,03-8,90). Conclusions These preliminary results suggest that some chronic diseases may have an unequal impact on thermal regulation and comfort. This is an important message also for those responsible for the development of policies against energy poverty. Key messages • At-home thermal discomfort is a relevant indicator to consider when monitoring chronic diseases and urban health. • Suffering from chronic diseases may have a relevant impact on thermal discomfort and this should be taken into account when defining policies against energy-poverty.


The term "detraction" was used by some of the older theologians 1 and even a few of the more recent authors, to indicate the defaming of another, whether by truth or falsity. Specifically, the harm done is the same. The Salmanticenses refer to detractio simplex as the unnecessary revelation of true but hidden crimes. Alphonsus 4 also distinguishes first between contumely and detraction, and includes calumny as a form of detraction. Today, commonly, "detraction" has acquired a specific and fixed meaning, as opposed to calumny, the latter having the character of a lie, as well as an injury to another's reputation. Obviously, what is said here will apply a fortiori to calumny. Detraction may be defined as follows: Detraction is the blackening of the good name of an absent person by unnecessarily revealing a true, hidden crime or defect. Blackening includes any dimming of the lustre; it does not require total destruction. The good name of a person may consist of either positive esteem or the negative aspect, the absence of unfavorable opinion. Detraction refers to an absent person; hence it excludes self-defamation or injury to one present, for this adds the note of contumely; this factor is not, however, of the essence of detraction. The person who is the victim of detraction may be either a physical or moral person, living or dead, known or unknown. The revelation must be unnecessary, that is, a reasonable cause for the revelation takes it out of the category of detraction. As indicated above, we restrict detraction to that which is true; if the defamation is false or exaggerated, it is calumny rather than detraction. The crime or defect which is revealed must have been previously unknown to the hearer, for there is no injury to a person's reputation through the discussion of what is already known.


In this paper, we present experimental results on millimeter-wave photodetection for a fiber-radio system. The experiment shows about 10 dBm and 7 dbm millimeter-wave output from the photodetector at 38 GHz and 60 GHz, respectively, which is close to the required power for a direct fed indoor millimeter-wave radiation system. To efficiently radiate the obtained millimeter-wave power, a CPW-fed slot antenna array directly integrated with the photodetector was designed and fabricated on a glass substrate at 38 GHz and 60 GHz. Simulation results for the antenna are also presented.

The core selected from Chengdong oilfield was immersed in the quasi-injected water with pH value 10.20 for 72 days at 60 ℃. The mass consistency of silica ionic (Si 4+ ) and that of aluminium ionic (Al 3+ ) with time changing of the core solvated in the water are acquired with ICP method. The dispersion characterstics of core immersed for 72 h are determined with Malvern grain size analysis. By comparing the experiment results, the amount of material solved from core is much less than that of the material being able to disperse and migrate from the core. Thus, the core dispersion and migration mainly contribute to the formation of secondary channel.


In allusion to commplicated inlet process of multi-gas resources for gas compressor station,the design on anti-surge control system is carried out for gas compressor operated at low-pressure(3.8 to 4 MPa)and medium pressure(5 to 6.5 MPa)at the precondition of centralized gas cooler allocated in gas compressor station.The design procedure is that anti-surege pipe loop and reeycling pipe loop for low-pressure and medium pressure are separately designed,the start/stop,operation,anti-surge and ESD(emergency shutdown)of gas compressor sets is operated by anti-surge controller.The field running shows that the anti-surge control system can effectively prevent gas compressor from surging.


John Rawls claims that the belief that there is but one reasonable and rational conception of "the good" is incompatible with political liberalism. A close examination of the thought of Thomas Aquinas, however, reveals that commitment to a particular conception of "the good" need not imply a rejection of liberalism. In fact, Aquinas' notion of political virtue anticipates Rawls' overlapping consensus. In addition, a thorough exploration of Aquinas' work indicates that, for the most part, he accepts the underlying assumptions that William Galston finds at the core of political liberalism.


Density functional theory (DFT) calculations were conducted to investigate mechanistic details of ethanol-to-butadiene conversion reaction over MgO or ZnO catalyst. We evaluated the Lewis acidity and basicity of MgO and ZnO and found that ZnO had the stronger Lewis acidity and basicity compared with those of MgO. Potential energy surfaces (PESs) of ethanol-to-butadiene conversion, which included relevant transition states (TSs) and intermediates, were computed in detail following the generally accepted mechanism reported in the literature, where such mechanism included ethanol dehydrogenation, aldol condensation, Meerwein-Pondorf-Verley (MPV) reduction and crotyl alcohol dehydration. DFT results showed that ethanol dehydrogenation was the rate limiting step of overall reaction when the reaction was catalyzed by MgO. Also, DFT results showed that ethanol dehydrogenation occurred more easily on ZnO compared with MgO where such a result correlated with the stronger Lewis acidity of ZnO. In addition, we computed ethanol dehydration which generates ethylene, one of the major undesired side reaction products for butadiene formation. DFT results showed that ZnO favored dehydrogenation over dehydration while MgO favored dehydration.


Evidence suggests that a surprisingly large fraction of firms comply with pollution emission standards even though expected penalities for noncompliance are low. We offer an explanation of this puzzle by extending the standard model of enforcement to include a self-seporting requirement and enforcement power.


We read the article 'Dentist-to-population and practice-topopulation ratios: in a shortage environment with gross maldistribution what should rural and remote communities focus their attention on?' by Tennant and Kruger with keen interest. Their groundbreaking findings are highly appropriate and commendable in the light of evidence of well-known and seemingly widening disparities in distribution of the dental workforce in rural and remote Australia. This is further compounded by the high burden of oral diseases, such as dental caries, missing teeth and poor perceived oral health status among rural and remote inhabitants overwhelmingly dominated by Indigenous Australians. In addition, the majority of Australian dentists (82.5%) are private practitioners.

The high magnitude and frequency of the shock load generated by the dynamic action of a satellite with a frame-panel configuration will lead to equipment damage on the satellite. However, the mechanical properties of the plate-rod coupling will result in a significant difference in the transmission and attenuation characteristics of the shock load. Moreover, the accuracy of the response analysis and evaluation of the key components are lacking. In this article, both direct integration and modal superposition methods are used to analyze the transient response of a satellite with frame-panel configuration. Furthermore, the advantages and disadvantages of the two methods are compared, and the possible factors affecting the precision and duration of the calculation results are presented. Simulation data show that the effect of time is very short for this type of explosion shock, and high-frequency modes require a larger proportion of the response provoked. Although the modal superposition method can solve the problem of a large amount of calculation and long computation time by modal order truncation and adjusting the time step, high-order modes are easily ignored, which affect the accuracy of the calculation results. The direct integration method is more suitable for the shock response analysis of the satellite with frame-panel configuration.


We have shown that Earth-mass planets could survive in variously restricted regions of the habitable zones (HZs) of most of a sample of nine of the 102 main-sequence exoplanetary systems confirmed by 25 September 2003. In a preliminary extrapolation of our results to the other systems, we estimate that roughly a half of these systems could have had an Earth-mass planet confined to the HZ for at least the most recent 1000 Ma. The HZ migrates outwards during the main-sequence lifetime, and so this proportion varies with stellar age – about two-thirds of the systems could have such a planet confined to the HZ for at least 1000 Ma at sometime during the main-sequence lifetime. Clearly, these systems should be high on the target list for exploration for terrestrial planets. We have reached this conclusion by launching putative Earth-mass planets in various orbits and following their fate with mixed-variable symplectic and hybrid integrators. Whether the Earth-mass planets could form in the HZs of the exoplanetary systems is an urgent question that needs further study


A gauge transformation provided by the three eigenfunctions of B a (x) � B b (x) (where B a (x), with a = 1,2,3, are the non-Abelian magnetic fields) exposes the topological configurations of the Yang-Mills fields. In particular, it gives Dirac monopoles interacting with 'photons' and massless charged vector bosons. A magnetic dipole field at each monopole corresponds to infinitesimal translation of the monopole, and

This article established artificial neural networks based on improved ant colony optimization evaluation model for residential performance. Firstly, on the basis of comprehensive analysis of the effects factors of residential building's performance, considering of the advantages of dealing with non-linear object of neural network, the neural network is trained by the sample data. While training neural network, the BP algorithm has good local performance but it is easy to fall into local Minimum, and the ant colony algorithm has good global performance, so the following combinatorial method is put forward. Then, the neural network is trained based on ant colony algorithm (ACBP algorithm) in global space, the parameters of neural network is trained using BP algorithm in local space. At 1ast, a case study carried out on the performance assessment of sample residential buildings using the model shows that the ACBP neura1 network outperforms BP neural network and AC neural network in the aspect of dynamic error forecast is verified by computer emulation example, and related conclusions are given.


AIMS
The purpose of this study was to validate patient's primary caregiver and their nurses' perception of patient discharge readiness assessment and their association with post-discharge medical consumption.

DESIGN
The study employed a descriptive research, prospective longitudinal study design.

METHOD
The study was performed in a ward of a medical center in Taipei, Taiwan, from June 2017 - May 2018. Obtained data were analyzed using an independent t-test, one-way ANOVA and logistic regression approach.

RESULTS/FINDINGS
The number of comorbidities and the number of days of hospital stay were positively associated with post discharge emergency room visits. Caregiver readiness for hospital discharge had significant negative correlation with patient's 30-day readmission. Both caregiver and nurse readiness for the hospital discharge scale (RHDS) score were not factors associated with the patient's 30-day emergency room visit.

CONCLUSION
Based on the research findings, to assess the discharge readiness as perceived by caregivers at patients' discharge is recommended.

IMPACT
Caregiver and nurse scores on readiness for hospital discharge showed a significant positive correlation. The higher the score of a caregiver's readiness for patient's hospital discharge, the lower the 30-day readmission rate. Family-centered care enables patients to safely pass though the transition phase from hospital to community and reduces the post-release consumption of medical resources. The discharge readiness perceived by caregivers should be included in any decision making.

 -(ethene-1,1,2,2-tetrayl)tetrakis(benzene-4,1-diyl) tetrakis(azanediyl)tetraacetic acid (TPE-(N-COOH)4), which is capable of reversible transition between polyion complexes (PICs) and hydrogen bonding complexes (HBCs) with tunable aggregation-induced emission driven by pH value. The PIC micelles could be formed via electrostatic interaction between ammonium cations and carboxylate anions under mild alkaline conditions. The formation of the micelles dramatically blocks the nonradiative pathway and enhances the fluorescence of TPE moieties, and the maximum fluorescence intensity was achieved near the isoelectric point due to the restriction of intramolecular motion. In addition, the fluorescence intensity and size of the PIC micelles exhibited a temperature response in the range from 20 to 80°C. Upon adjusting the solution pH to 2, the PIC micelles were reconstructed into hydrogen-bonding complexes while the hydrogen bonding interaction between the protonated carboxyl groups of TPE-(N-COOH)4 and chitosan. Moreover, the size of the micelles underwent a remarkable decrease, whereas the fluorescence emission was further enhanced by ~6.25-fold. The pH actuated micellar transition from PIC to HBC with tunable fluorescence performance is fully reversible. This study provides novel multifunctional materials that are of great importance for their potential application in the fields of optoelectronic devices and chemical and biomedical sensors.


As the size of the industrial systems increases, more and more topic messages need to be published and subscribed to in industrial scenarios such as microgrids and manufacturing industries. A priority scheduling algorithm based on the hotness of message topics is proposed to address the problem of efficient distribution of messages with different topics in microgrids. It is an algorithm that gives different priority permissions according to the number of topics, so that in the face of a large number of different topic messages, the data messages with a higher number or urgency can be transmitted first, solving the problem of port blocking when the server distributes the messages. At the same time, to prevent low priority data from sending timeout or waiting for a long time, a time period is set up, a low priority transmission mechanism is set up within a specific time period to ensure that the system can send data to customers in a timely and accurate manner. The results show that the priority design in this paper can well solve the power scheduling problem of multi-target data transmission and ensure the transmission efficiency of messages in the microgrid system.

It is true that, for a variety of reasons, declarations of war have largely fallen into disuse since World War II. Part of the reason may be that following the introduction of nuclear weapons, major interstate war has all but disappeared.[2] Moreover, the establishment of the United Nations (UN) largely obviates the need for individual nations to declare war. Other than acts of immediate self-defense in conformance with the UN Charter,[3] it is the collective action of the Security Council, rather than the individual acts of states, that ordinarily authorizes "the use of force to maintain or restore international peace and security."[4]
