Rat-liver ATP citrate lyase was purified to homogeneity and subjected to limited proteolysis by subtilisin, trypsin and chymotrypsin. Each ofthe three proteases yielded two peptides of Mr about 68000 (F-68) and Mr 53000 (F-53) but the subtilisin-derived larger fragment was further degraded to two peptides of Mr 37000 (F-37) and 25000 (F-25).

2
The fragments formed initially had the unimpaired ATP citrate lyase activity and also unimpaired acyl-CoA lyase activity. The former of these but not the latter was destroyed on degradation of fragment F-68 (subtilisin) to fragments F-37 and F-25.

3
Fragments F-53 as formed by all three proteases, and fragments F-70 (chymotrypsin), F-68 (trypsin) and F-(37 + 25) (subtilisin) were isolated chromatographically in homogeneous form.

4
The isolated fragments F-70, F-68 and F-(37 + 25) were characterized as acyl-CoA lyases. The F-53 specimens were enzymically inactive in the applied assays for partial reactions but yielded ATP citrate lyase activity on recombination with fragment F-70 or F-68, not however with fragment F-(37 + 25).

5
From these results and the known position of the catalytic phosphate of ATP citrate lyase it was concluded that limited proteolysis occurs primarily at a region separating acyl-CoA lyase plus part of thiokinase regions from residual thiokinase.

6
A correlation of the sites of catalytic and structural phosphate with distinct functions of the enzyme is presented.


Background: The rate of cesarean sections performed worldwide are increasing and this rising trend is seen in both developed as well as developing countries. However in the present scenario, the rise in total number of cesarean delivery is partially attributed to the large proportion of repeat cesarean deliveries due to decline in the frequency of VBAC (vaginal birth after cesarean). Therefore it is imperative to know the various determinants of maternal and perinatal complications. Methods: A hospital based prospective observational study was done in the Department of Obstetrics and Gynecology, Pondicherry Institute of Medical Sciences (PIMS). A total of 103 women at ≥34weeks period of gestation with singleton pregnancy in cephalic presentation and previous one lower segment caesarean section (LSCS) were enrolled in the study. Women who were eligible were given a trial of labor. Results: Eighteen patients delivered vaginally and 85 by cesarean section. Almost one-fourth of the newborns, (n=25, 24.3%) had one or more complications. There were 10 (9.7%) women who had complications. Co-morbidities in the mother and gestational age at delivery were the single most important determinants of complications among mothers and newborns. Conclusions: It is critical to evaluate maternal and neonatal outcome in patients with prior cesarean delivery, as well as their determinants.


Some animals uses the ultrasound with hyperbolic frequency modulation(HFM) form for echolocation.Hence the performance of underwater signal processing system can be enhanced by making use of the characteristics of the bionic signal.In this paper,the peak ridge characteristic of wideband bionic signal is described,then a detection method based on wavelet-Radon transform is presented,which converts the wideband echo detection into a linear detection on wavelet transform plain.Simulation results verify that the presented method makes full use of the characteristics of the wideband bionic signal,and the wideband HFM signal is applicable for underwater signal processing system.

Purpose. Establish theoretical and methodological problems of studying the categorical pair "trust-distrust" and clarify the correlation of these phenomen's. Methodology. For basis the transdisciplinary approach related to principle of syncretism in the comprehension of results of disciplinary and interdisciplinary research practices at metatheoreticallevel is taken. Methodological options and principles are used structural-functional and phenomenological approaches; conceptual ideas about a sociocultural crisis in Russian society; procedures of categorizing and conceptualization, and also principles of discourse analysis. Results. It was revealed that the notions of trust and mistrust in disciplinary research practices are fragmentary, due to the difference of paradigmatic approaches and author's methodological preferences. Based on the principle of syncretism in the study of trust and mistrust, it is justified that trust and mistrust act as a holistic phenomenon of social practices determined by the transformational changes of any society. Therefore, trust and mistrust should be the subject of social-philosophical understanding, suggesting their syncretic treatment as an integral social reality. Practical implications. The results can be used to develop normative strategies for the functioning and transformational changes in society, are taken into account in solving a certain range of social problems when developing models of social management and drawing up social programs that take into account the social and regulatory significance and social effect of trust.

Abstract : Afghanistan has the dubious distinction of being the largest opium-producing country in the world. Seventy-five percent of the world's heroin which is obtained from opium poppies comes from Afghanistan. Opium exports brought Afghanistan $1.2 billion last year equaling the total of international aid to the country for the same period. Although the Afghan government and Islamic religion disapprove of growing poppies, other major influences-economic social and political-promote poppy farming. The United States government has an interest in controlling the influx of heroin into this country as well as an interest in a strong stable Afghan government and a stable south Asia region. This paper will describe the background leading to Afghanistan's position as the world's leader in opium production explore possible United States responses to this troubling situation and recommend a course of action.


We have demonstrated the functional lipid vesicles based on artificial electric-taste sensor capable of identifying NaCl, HCl, sucrose and quinine. It used the membrane modified gold electrode with neutral, positive, negative, hydrophilic vesicles. The discriminative character of our taste-sensors has been confirmed by evaluating them against four basic taste solutions using electrochemical method. Each taste sensor was exhibited variations in electric current response when exposed to the four basic taste solutions. The principle component analysis (PCA) on our sensor was clearly recognized against four basic tastes.


Background: Basal cell carcinoma (BCC) represents themost common type of facial skin cancer in Middle East andEgypt. It rarely metastasizes, but because of its locally destructivenature, it can cause high morbidity. Reconstructionby local flap after surgical excision depends on the size ofthe defect and the affected facial aesthetic unit.Aim: To reveal the prevalence of facial BCC, relation ofits site to facial aesthetic units and type of local flaps usedfor reconstruction per units.Patients and Methods: A retrospective study was conductedon 80 patients with facial BCC that admitted to the outpatientclinic, Plastic Surgery Department, Qena University Hospitalfrom June 2018 to May 2020 (2 years duration). Only earlystageand primary tumors were included. Statistical analysis:Data was analyzed using the Statistical Package for SocialSciences (SPSS) version 24.

There are many different local flapsavailable depending on the particular facial subunit thatrequires reconstruction. Careful recognition of the principlesof the facial subunits will equip the surgeon to achieve thebest possible functional and aesthetic outcomes.


This chapter addresses the moral crisis. One of the oldest tropes in the "end of the world" genre is "We are going to die because of a moral crisis." The ancestor of this argument is Edward Gibbon, author of The History of the Decline and Fall of the Roman Empire. Moral arguments can be made by anyone in any part of the political spectrum; they are the most common, however, among the religious right. The chapter then considers Jim Nelson Black's book When Nations Die: Ten Warning Signs of a Culture in Crisis. Black's treatment is unusually complete and covers nearly every argument made by moral crisis authors. Ultimately, societal survival is based on large groups of people working together to solve common problems. Identifying one group as having superior values and another group as being barbarian reduces the size of the potential web of cooperation. Indeed, it is not helpful to set rich people against the "idle" poor, white people against "criminal" blacks, or Christians against "culture-destroying" vulgarians.


This paper examines, from a sociological perspective, the power relations between a rural cultural practice, the copla (a form of oral poetry) and the urban context, represented by the civil authorities and the audience in the context of the «Fiesta de la Pachamama», which is carried out in Amaicha del Valle, Tucuman, and institutionally acknowledged by the Argentine state. The results here presented are part of a broader research on the practice of the copla in Northern Argentina.

Methods A total of 126 patients were assessed from July 2012 to July 2015, including 210 implants. The patients were followed for more than 2 years. Univar⁃ iate and multivariate survival analyses were performed using logrank tests and Cox regression analysis to identify risk factors for dental implant failure with the immediate loading or conventional loading of anterior teeth. Results The 2⁃ year survival rates of anterior implants with delayed and immediate loading were 96.3% and 89.0%, respectively. The difference between the two groups was statistically significant(P < 0.05). The 2⁃year survival rate with delayed loading of implants was higher than that of the immediate loading of implants. Survival analysis indicated that the risk factors for implant failure were smoking and maxillary implantation in both the immediate loading and conventional loading groups. Conclusion There is high risk associated with the immediate loading of anterior implants. The immediate load⁃ ing of maxillary anterior implants and smoking in association with implantation may cause implant failure. 【Key words】 Immediate loading; Anterior implant; Risk factor; Maxillary implantation; Smoking


One effective way to improve the water resistance of gypsum binder is to add a hydraulic additive consisting of Portland cement and an active mineral additive regulating the formation of highly basic compounds. Various natural and artificial mineral substances are used as additives. It is known the effectiveness of fine-ground natural zeolites of the "Honguruu" (hongurin) deposit in the process of composite gypsum binders (CGB). There are also separate studies proving the increase in the activity of zeolites during their calcination at temperatures of 300-400 ° C. This paper presents the results of the study of the effect of the calcination temperature of hongurin on the properties of CGB. As a result of the studies, the optimal calcination temperature of hongurin - 180 ° C was determined. At the same time, the activity of hongurin increases, which provides significant growth of mechanical indicators of rock on the basis of CGB: the ultimate strength at compression of samples at the age of 28 days from compositions without plasticizer increased by 90% at addition of plasticizer in the amount of 1% - by 35%, and at 2% - by 57%. But with the use of calcined hongurin there is a slight decrease in the water resistance of the rock: in the optimal composition from 0,96 to 0,87, it is explained by the decrease in the activity of hongurin due to the reduction in the number of active groups, and the resulting new centers have a Lewis character.


The effect of aliasing on sampled noise power measurements is investigated. It is shown that although aliasing does not bias noise power measurements, it can significantly increase the measurement variance. The equivalent noise bandwidth (EENBW) of a sampled data system is defined by equating the mean and variance of the noise power measurement to those of a system with a rectangular spectral response. With this definition, which is shown to be consistent with that for analog systems, it follows that the ENBW is bounded by the smaller of the analog ENBW or half the sampling frequency. Practical examples of sampled-data systems are used to demonstrate the increased variance, integration time, and noise spectral density that accompany aliasing. >


In this thesis it is analyzed how State and different actors promote actions of development in the Zambezi Valley region. For that it is emphasized different historical periodes that determined the specific forms of political and economical uses of the territory and its implications on the process of development of the Zambezi Valley region; the participation of private sector, civil society and rural families in the promotion of the development. Verticalities and horizontalities are examined like a theoretical important couple for the analysis of the relation between power and territory, determinants for the understanding of socio-spatial dinamics in the region in study. Nevertheless, it is tried to demonstrate along seven chapters of the thesis by using secondary and empirical data collected in five districts of the Zambeze Valley region, namely Marromeu, Morrumbala, Moatize, Báruè and Cahora Bassa that the verticalization of actions and decisions are more expressive and dominant. It means the use of the territory of the Zambezi Valley region as resource of economical value for the viability and satisfaction of interests outsider to the region. The economical use is put on top of the social use. This means that the districts and the region as a whole present themselves passive and receiver of the chain of decisions and implementation of projects conceived out or far from there. Evidences are Cahora Bassa dam, sugar industries, exploration of coal and tobacco, impositives politics and idealized from abroad, strong external dependence, among other factors. In this perspective, the Zambeze Valley region is transformed into a place of finalities, the obedient daily life, imposed from abroad. The inquiry was driven by using the inductive method based on an intentional sample operationalized from the local scale (districts). This made possible to do the inference for large scale (the region) taking like standard the socio-economic dinamics registered in five districts studied. Key-words: Zambezi Valley region. Development. Regional development. Region. Territory. Verticalities. Horizontalities.


This paper is dedicated to the simulation of the so-called trapping-effect observed in the Troitsk nu-mass experiment. The effect is caused by the magnetic trapping of decay electrons in the windowless gaseous tritium source and the gradual evaporation of those electrons. As a result, alongside regular tritium beta-spectrum electrons, we see additional electrons that are initially trapped in the source and escape it with changed energy. The spectrum of evaporated electrons is quite peculiar (almost flat for monochromatic initial electrons) and could not be directly measured in the experiment. So one has to rely on simulations. Also, it is possible that the same effect could be observed in other cases of magnetic traps.


One of the main reliability concerns in the nanoscale logic is the time-dependent variation caused by Negative Bias Temperature Instability (NBTI). It may increase the switching threshold voltage of pMOS transistors and as a result slow down signal propagation along the paths between flip-flops thus causing functional failures in the circuit. In this paper we propose an approach to identify NBTI-critical paths in nanoscale logic that is based on analyzing combination in different degrees of the three parameters: delay-critical paths, gate input signal probability and the gate fan-out degree along the paths. Further the identified NBTI-critical path can be used e.g. for introduction of aging sensors circuitry, rejuvenation stimuli generation, etc. The proposed approach is demonstrated on an industrial ALU circuit design.

This paper reviews the magnetic fields available in pulsed coils and in continuous operation, using normal conductors. The new laboratory now coming into operation at the Massachusetts Institute of Technology is described. This involves primarily four generators designed to produce 10 000 A continuously, and current pulses up to 40 000 A each for times diminishing to a few seconds, and at voltages of 200-250 v. The power and corresponding cooling water can be made available at ten locations by remote control. The generators may be operated independently and simultaneously or in any series or parallel combination desired. The thinking that has led to a 250 kG magnet and a 100 kG high precision magnet is reviewed. A magnet to produce in excess of 400 kG in a 2 second pulse, and requiring 32 MW, is under consideration.


The current status of the research on mercury cadmium telluride(MCT) defects is reviewed by summarizing and analyzing the related papers published in recent years.MCT offers significant advantages over other similar semiconductors.This has made it to be the most widely used narrow gap material in infrared focal plane array(FPA) devices.The defects in MCT epilayers can inhibit the pixel performance and operatability of the FPA fabricated with this material.The type,orientation,and growth temperature of the substrate etc.are the factors which have apparent effect on MCT epilayer quality.To grow high quality MCT epilayers,different factors which may result in defects should be further understood and controlled properly.Significant progresses have been made in the epitaxial growth of MCT with the aid of various fabrication and characterization techniques.


As a promising wireless network virtualization technology, virtualized base station (BS) has been proposed to tackle the problem of low-efficient utilization of BS's computing resources, e.g., baseband processing units (BPU). In this paper, we design a novel scheme to achieve the efficient BPU allocation based on a contract-theoretic approach. To achieve this, we consider the BPUs as a kind of trading resources. We establish a monopoly market, where the infrastructure provider (InP) is the monopolist owning all the BPUs, and multiple mobile network operators (MNOs) intend to rent BPUs from the InP for processing their baseband signals. In such a market, the InP offers a set of quantity-price contract items to the MNOs based on statistical information of their types, and at the same time, the MNOs are stimulated to accept the offers for the purpose of making profit. We propose the optimal contract design to maximize the InP's profit, as well as develop an incentive mechanism to guarantee each MNO choosing a proper contract item. Numerical results validate the effectiveness of our incentive mechanism for BPU resource allocation.


Recent flight tests of a NASA supermaneuverable fighter aircraft indicated a susceptibility to a form of aircraft-pilot coupling referred to as pilot-induced-oscillation. This coupling resulted in very degraded handling qualities in air-to-air tracking tasks performed at high angle of attack. A pilot-model based analysis of the vehicle and task was conducted with the goals of: (1) analytically corroborating the oscillation tendency and poor handling qualities, and (2) determining improvements to the flight control system which would alleviate the oscillation tendencies and improve overall handling qualities, and involve as few changes to the existing flight control system as possible.


Java is rapidly becoming the language of choice in a wide range of applications from networking to scientific to business. Other languages can gain the power of Java by compiling to Java or to its bytecode. Source to Java translation is an attractive option because it is faster to implement and offers advantages in retaining the structure of the original program as well as the possibility of linking in with Java classes which use graphics, networking and so on. Yet translating to Java presents certain challenges, and these can be overcome in a variety of ways. This paper surveys twelve projects which have used source to Java translation and evaluates the pros and cons of the approach. It then goes on to consider in detail a new source to Java translator for Darwin, and architectural description language. The target of the translation is not just Java, but also a communication system for distributed processing, which was also completely redesigned using Java's RMI. The system was successfully implemented and has no performance degradation compared to the previous C++ version.


The pharmaceutical formulation is the phase of the development of a new drug involved in the transformation of the active ingredient in the final dosage form suitable to patient administration in order to achieve its therapeutic purpose. It was discovered that the formulation study can improve the characteristics of the active ingredient. In recent preliminary trials the possibility of modulating the drug release according to the need of the body should be obtained.


In his book's subtitle Symes promises 'a material history of classical recording'. But in this case, history does not mean chronology. Instead of this, the author gives an inventory of different discourses on classical recording with some excursions on historical aspects. Here, sometimes, it is not quite clear which period the author deals with. The second term of the subtitle, 'material', seems to focus on technological aspects. The record's evolution from the gramophone to the LP and the CD, indeed, is a main topic of this book and Chapters 2 and 3 deal with this topic. However, the first chapter develops a textual theory. According to Michel Foucault he states that discourses help 'to create a language for speaking and thinking about the phonograph that drew on existing cultural vocabularies and ideas' (p. 6). Correspondingly, Chapter 2 does not concentrate on the development of the recording studio but analyses the esthetical discourse of the performers about the musical possibilities illustrated by the extreme positions of pianist Glenn Gould who abandoned his concert activities to improve his musical ideas in the studio, and of conductor Celibidache who refused to record at all in his later career. In Chapter 3, Symes explores the discourses which accompanied the evolution of a more and more 'original' sound. The next two chapters translate Gerard Genette's theory of paratexts to the record. Chapter 4 about the iconography of record covers lists merely descriptively a lot of covers. In Chapter 5, Symes investigates a much larger ground than he promises in the chapter's subtitle 'Some Notes on the Sleeve'. For instance, Symes compares the programming of the record and of the concert: as a rule, programs on records are more homogeneous and couple, for example, two violin concertos which would be very rare in a concert (p. 128). Chapter 6, about the narrative architecture of gramophone magazines, exemplified on the oldest record journal 325


Rural and remote patients with rheumatoid arthritis (RA) are at risk for inequities in health outcomes based on differences in physical environments and health care access potential compared to urban populations. The aim of this systematic review was to synthesize epidemiology, clinical outcomes, and health service use reported for global populations with RA residing in rural and remote locations.


The determination of Chlamydia psittaci ( Cp ) in psittacida birds in zoological parks in Venezuela represents a strategy of conservation and preservation for this group of birds, where multiple species are threatened with extinction and others have lost their capacity of reincorporation to their natural habitat. Through the nested polymerase chain reaction (PCR) the 16S subunit of Cp DNAr was amplified in 50 cloacal swab samples from psittacine birds, reporting a frequency of 62 %. The work was carried out in the Zoo Park  Las Delicias (PZD) 8% and the Aquarium of Valencia (AV) 54%.  The high frequency was associated with a genotype of low concentration and virulence due to the absence of clinical signs of avian chlamydiosis.  These results demonstrate the need to promote the detection of Cp, mainly for the AV that acts as a center of reception of specimens of confiscation, and, like the PZD, have other species vulnerable to extinction with risk of infection to Cp .

The Indian pharmaceutical industry (IPI) has been largely influenced by the changes in the patent regimesin India. This paper, besides reviewing the evolution of IPI, studies the trends of research and development(R&D) and patenting of pharmaceutical firms and identifies the determinants of R&D. It examines theinterdependence between R&D and patenting, and firms' overall performance. Secondary data analysis indicatesthat the product patent regime has impacted the R&D intensity of IPI firms. The analysis of primary datacollected from 64 pharmaceutical firms identifies three distinct clusters of firms of IPI. The firms' performance,measured by the rate of capital employed by the three groups of firms, indicates that superior R&D and a largenumber of patent filings need not necessarily imply a better performance. The paper adds to the extantliterature on IPI by bringing forth implications which are important for formulating appropriate action plans toenable pharmaceutical firms to efficiently employ their resources in the product patent era. http://dx.doi.org/10.14429/djlit.32.3.2379


Abstract:This article draws on historical linguistic evidence, archeological finds, and written accounts of ancient practices to argue that, in the pre-Qin and Han periods of Chinese history, an important stratum of knowledge related to earthly energies, vibrations, pitch, tonality, music, memory, and recitation existed in conceptual parallel to systems of visual knowledge of heavenly bodies, light, color, and the written record. Masters of the former set of skills were frequently blind and entrusted with a distinct set of ritual and advisory functions, including ushering in the seasons, pronouncing on elements of the calendar, predicting military fortunes, and performing official policy admonishments. Of particular importance to this group of experts was the concept of "winds" or "airs" (fēng) and a closely related verb for "sing," "chant," or "remonstrate" (fĕng). The etymological relationship of these words, along with words for listening, smell, sounds, and fragrance, led to a conceptual blending whereby the "energy" (qi) of wise words and "fragrant" virtue could carry on "winds" of oral transmission to correct public morality and governance. This led to an etiological hierarchy, in some ways inverted by current standards, in which the purpose of studying pitch and tonality was not, first and foremost, analysis of music qua art but, rather, the encoding, transmission, and influence of natural energies and social harmony.


The aim of this study is to evaluate the PESERA soil erosion model as a tool for predicting soil erosion at a catchment scale in a high latitude agricultural catchment in eastern Scotland. We investigate the importance of the resolution of soil and terrain data and the sensitivity of the model to rainfall inputs and therefore it's potential to be used as a tool to model the changing risk of erosion posed by changes in rainfall distribution. We show that the model does have the potential to be used as a land use planning tool in an attempt to minimise sediment loss and preserve water quality. We also show that the model has the potential to be used both as a screening tool due to its relatively limited data requirements and at a finer resolution where more detailed data are available, making it a powerful tool for soil erosion research.

Whether, when, and why individuals prepare for disasters are major concerns of disaster preparedness researchers. Using population-based survey data collected after the 1994 Northridge earthquake, multinomial logistic models are imposed to examine if preparedness activities were adopted after the quake because of quake-related financial loss, physical and emotional injury, and proximity to the earthquake epicenter and shaking. The extent to which people invest in sustained preparedness was also examined by comparing the preparedness activities occurring both before and after the earthquake. The results indicated that exposure to physical, financial, and emotional injuries, and to shaking increased post-quake preparedness. Engaging in certain types of pre-quake preparedness increased the likelihood of post-quake preparedness. Post-quake preparedness is not affected by socioeconomic status or demographic factors, except that married persons are more likely to prepare in all situations and immigrants are more likely to adopt post-quake preparedness activities.

ABSTRACT This paper proposed a new quadratic boost converter featuring a high voltage conversion ratio, high efficiency, and comparatively low inductor currents using reduced redundant power processing and voltage lift configurations for PV applications. The proposed Quadratic Boost Converter (QBC) consists of fewer components and improves voltage gain at a lower duty cycle. Furthermore, the inductor and capacitor are controlled to reduce output current and voltage ripples. The operational modes, steady-state analysis, design aspects, and dynamic modelling of the converter in continuous conduction mode are discussed clearly. The performance of the proposed QBC is compared with different existing converters in terms of component count, voltage gain, voltage and current stress of the switching components, effective index, total switching device power, and component losses. A110W hardware prototype has been developed. The simulation and experimental results of the converter validate its performance and stated benefits. The efficiency curves for the proposed QBC for various load currents are presented, with a peak efficiency of 93.8%.


The alarming speed of COVID-19 pandemic spreading is not only a global health crisis but also brought severe economic consequences globally, including supply-chain disruptions, temporary shut-down of production facilities etc. As one of the core business functions, the recruitment arm of the Human Resources (HR) Department was also severely hit by the effects of the pandemic and creating tremendous uncertainty. No one feels confident about what is coming next, yet everyone needs to make decisions now which will have long- term implications. In addition, to ensure that the organisations remain competitive and to aid the business growth, it is the responsibility of the HR Department to be able to source and recruit the best talent. Many organisations had adopted the global recruitment strategy that offers expatriate packages to attract foreign talents with specific skillsets complement the local talent pool. However, the travel restrictions in place added a level complexity to the application of work passes and entry permits for foreigners for border entries. Some drastic changes happened during that period to ensure business operation keep going as usual. Desperate measures has been taken and replacing the conventional way of doing things. This includes recruitment process in organization as well. Thus, the organisations need to identify the need to redefine the way they attract the best talent in an age of disruption. Therefore, this conceptual paper attempts to provide the understanding on how to achieve that.

For a three-layer neural network (one hidden layer) with its inputs and outputs not restricted to binary ones, the authors obtain conditions under which a given set of input patterns is mapped to an arbitrary set of output patterns. It is shown that the existence of J-1 hidden units is the necessary and sufficient condition for J input patterns, if the hidden units take binary values. When the number of the binary hidden units is infinity, it is proved that the resulting network simulates a three-layer network with infinite hidden units, whose activation function is absolutely integrable, and that the outputs from the network are arbitrary for continuous-valued inputs. It is also shown that the existence of an infinite number of hidden units is not only sufficient but also necessary if the activation function for the hidden units becomes discrete at most at the countable points.<<ETX>>


In order to improve the global localization accuracy, the influence of gross errors and the real-time localization information in the cooperative localization of autonomous underwater vehicle system under clutter interference, a local information fusion algorithm based on information gain is proposed. In this paper, the reliability of each measurement information is investigated from information entropy theory, and the multi-group local filtering information of the multi-master underwater vehicle is optimized. Taking the information gain as the weight, the multi-group filtering results are fused to generate the localization information measured from the AUV. A parallel structure of local information filtering and information gain weighting method is proposed, which utilizes a real-time update mechanism to ensure that the input values of the information weighting algorithm come from the latest local filtering output values. In the end, simulation results demonstrate that this method can effectively reduce the absolute error of local filtering and improve the localization accuracy.


The functional connectivity and dynamics of resting-state networks (RSN-FC) are vital for cognitive functioning. RSN-FC is heritable and partially translates to the anatomical architecture of white matter, but the genetic component of structural connections of RSNs (RSN-SC) and their potential genetic overlap with RSN-FC remains unknown. Here we perform genome-wide association studies (Ndiscovery=24,336; Nreplication=3,412) and in silico annotation on RSN-SC and RSN-FC. We identify the first genes for visual network-SC, that are involved in axon guidance and synaptic functioning and show that genetic variation in RSN-FC impacts biological processes related to brain disorders that have previously been associated with FC alterations in those same RSNs. Correlations of the genetic components of RSNs are mostly observed within the functional domain, whereas less overlap is observed within the structural domain and between the functional and structural domains. This study advances the understanding of the complex functional organization of the brain and its structural underpinnings from a genetics viewpoint.


The Romanian economy passes through a difficult period marked first of all by a structural crisis which is manifested especially at the level of industrial structures. The economical obstacles are increased by the fact that the process of restructuring the Romanian industry took place and will continue to develop in less favorable conditions, marked by a relative destabilization of the production. This circumstances have generated an underproduction crisis followed by the intensification of the competition on the global market. All these led to the necessity of some structural changes required by the conjuncture and to some distortion effects reported to the ones obtained into a mature market economy. Considering the situation revealed in this work by the multi-criteria analysis of the romanian industry competitiveness, also based on the influence factors and the exigencies of the objectives of the EU competitiveness policy, we think that the major purpose of the industrial policy actions in Romania in the near future should be the enforcement of a coherent package of policies for the creation of and increase of the competitive advantages.


A database is assembled which contains electron-impact ionization rate coefficients for selected atomic ions in the Na isoelectronic sequence. The rate coefficients are obtained from a Maxwellian convolution of distorted-wave cross sections which include direct ionization of the 2p and 3s subshells, as well as inner-shell excitations from the 2s and 2p subshells leading to autoionization. These excitation-autoionization contributions can be large for many Na-like atomic ions. To assist modeling efforts of moderately dense plasmas, the rate coefficients are resolved as to the final state of the ionization process. A sample database file is presented for Fe15+. The complete database will reside in electronic form at the Controlled Fusion Atomic Data Center at ORNL (http://www-cfadc.phy.ornl.gov/data_and_codes/).


This paper is focused on different use cases of fiber optic sensor deployments in harsh environments for environmental, hydrogeological, and chemical sensing applications. One of the applications is distributed monitoring of soil and groundwater during in-situ thermal remediation of brownfields. The unique advantages of fiber Bragg grating (FBG) sensors are demonstrated through the development of transducers for distributed sensing of soil temperature and level of groundwater which are critical performance parameters for assessing the efficiency of environmental remediation projects. In addition, research studies are presented in this paper on the development of fiber optic pH sensors for soil and subsurface monitoring applications using a stimuli responsive polymer coated on fiber Bragg gratings.


Companies that want to succeed in making a profit and can survive for years by growing and developing, they should not rely on past ways of working that are less efficient, less expert and less professional. Price, Product Quality and Service Quality are some of the factors that influence consumer buying interest. Quality products and services at affordable prices will attract consumers to buy. The purpose of this study is to determine the effect of Price, Product Quality and Service Quality on consumer buying interest in Sepakatea Adertising Broni Jambi City. The method used is the Quantitative research method. The number of samples in this study was 81 people. Multiple Regression Analysis is used as a data analysis technique. From the data obtained, the results showed that the Price Variable had a positive but not significant effect on consumer buying interest, the Product Quality Variable had a positive and significant effect on Consumer Buying Interest and the Service Quality Variable did not have a significant effect on purchasing decisions. Based on the data analysis in this study, these variables are valid and reliable.


A configuration interaction study of the lower‐lying electronic energy levels of molecular oxygen is made. With the 1s and 2s shells kept filled, the remaining eight electrons are distributed among the twelve spin‐orbitals arising from the 2p levels on each atom. The atomic functions are represented as Gaussians, which are poor atomic functions but facile integrands in many‐center integrals. The molecular orbitals are formed as symmetrical linear combinations of the atomic orbitals, simply for convenience. Inclusion of all configurations implies complete equivalence of all possible constructions of linear combinations.Out of the 495 configurations (many‐electron determinants) a group of nine states of 3Σg− character is set up and twelve of 1Σg+ character. The interaction matrix of each block is computed and diagonalized (by electronic computer). The results for the ground state, which is a triplet, are very good. The binding energy is off by 2 percent, the internuclear distance is off by 1 percent, the fu...


Socioeconomic inequalities in the double burden of child malnutrition threatens global nutrition targets 2025, especially in Eastern and Southern Africa. We aimed to quantify these inequalities from nationally representative household surveys in 13 Eastern and Southern African countries between 2000 and 2018. 13 of the latest Demographic and Health Surveys including 72,231 children under five year olds were studied. Prevalence of stunting, wasting and overweight (including obesity) were disagregated by wealth quintiles, maternal education categories and urban-rural residence for visual inspection of inequalities, and the slope index of inequality (SII) and the relative index of inequality (RII) were estimated for each country. Country-specific estimates were pooled using random-effects meta-analyses. Regional stunting and wasting prevalence was higher among children living in the poorest households, with mother's with the lowest educational level and in rural areas. In contrast, regional overweight (including obesity) prevalence was higher among children living in the richest households, with mother's with the highest educational level and urban areas. Tackling social inequalities in the distribution of the double burden of malnutrition among children in the Eastern and Southern African region will require strategies that address the reasons socially disadvantaged children became more exposed to stunting or wasting.


Until now several studies of rotating structures like rings or shells have been done. To model such problems in a right way, geometrical nonlinearity has to be considered. Different methods can be used, to solve the corresponding eigenvalue problem. In this article the focus will be placed on the finite element method.

Effect of tube feeding method on establishment of oral intake in stroke patients with dysphagia: comparison of intermittent tube feeding and nasogastric tube feeding. Jpn J Compr Rehabil Sci 2015; 6: 1-5. Purpose: To compare the effects of two tube feeding management methods; nasogastric tube feeding and intermittent tube feeding, implemented during the process of rehabilitation for dysphagia due to cerebrovascular disorders on the outcome of oral intake. Methods: Dysphagic patients who were admitted to convalescent rehabilitation wards because of cerebrovascular disorders were divided into two groups: 398 patients who underwent nasogastric tube feeding (NG group) and 114 patients who underwent intermittent tube feeding (ITF group). The two groups were compared with respect to outcome of dysphagia rehabilitation. Results: The proportion of patients who were able to meet nutrition needs by oral intake of three meals alone at discharge was significantly higher in the ITF group than in the NG group (71% versus 53%, p = 0.0007). The proportion of patients showing improvement in food intake level scale (FILS) during hospitalization was also significantly higher in the ITF group (p = 0.007). The mean duration from admission to start of direct training was significantly shorter in the ITF group than in the NG group (9.6 ± 13.9 days versus 19.1 ± 25.8 days, p = 0.001). The mean duration from admission to start of oral food intake was also significantly shorter in the ITF group than in the NG group (20.1 ± 26.4 days versus 27.3 ± 31.8 days, p = 0.049). Conclusion: The results in this study suggest that tube feeding management using ITF achieves better outcome of dysphagia rehabilitation compared to using NG.


Academic research has repeatedly emphasized the importance of firms accessing external information sources in their conduct of exploitation and exploration, ascribing boundary spanning a pivotal function. This paper builds upon this notion focusing on the individual managers vested in the role as boundary-spanners. Drawing on social-psychology, the concept of role theory is applied to argue that managers´ perceived role autonomy in interpreting and enacting their boundary-spanning function impacts their engagement in exploitation and/or exploration. Role autonomy is explained by the interactive effects of role making and role taking, each conceptualized by two variables, namely employees` tenure and personality and corporate structure and culture, respectively. I contribute to existing ambidexterity literature on the individual level by developing a conceptual model on the intrinsic and extrinsic dynamics that affect the engagement in both innovation types. Further, this analysis has significant implications for research on ambidexterity and extends and applies the concept of contextual ambidexterity to the inter-organizational level in particular.


The invention relates to a method for shaping a front edge of a megawatt wind-power blade. The method is implemented by the following steps of: starting from the blade root end, by using CAD software, taking a section with a certain length till the blade tip, and making a clamping plate in a ratio of 1:1 according to the section on the front edge vertical to the axial direction of the blade at the fixed interval; for the blade which is demolded, starting from the root end, scraping an adhesive (called a bottom) on the front edge of the blade at the fixed interval, laying demolding cloth, clamping the bottom by using the front edge clamping plate along the vertical direction of the blade, flattening the bottom, curing the bottom, grinding the roughness of the surface until the bottom is grinded on the same line; distinguishing the surface of PS and the surface of SS, can not take these backwards; coating the adhesive in an area between two bottoms, scraping the adhesive by using an angle iron which is longer than the distance of adjacent clamping points along the radian of the bottom, curing, and grinding the adhesive to roughness; and filling up the front edge which is primarily trimmed by using coarse putty. By adoping the method of the invention, the repaired front edge of the blade is consistent with standard blade shape and has good pneumatic performance.


Abstract Background : Pancreatic cancer is a leading cause of cancer-related mortality in the U.S. and both incidence and mortality are highest in African Americans. Obesity is also disproportionately high in African Americans, but limited data are available on the relation of obesity to pancreatic cancer in this population. Methods : Seven large prospective cohort studies pooled data from African American participants. Body mass index (BMI) was calculated from self-reported height and weight at baseline. Cox regression was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for levels of BMI relative to BMI 18.5-24.9, with adjustment for covariates. Primary analyses were restricted to participants with ≥5 years of follow-up because weight loss prior to diagnosis may have influenced baseline BMI in cases who died during early follow-up. Results : In follow-up of 239,597 participants, 897 pancreatic cancer deaths occurred. HRs were 1.08 (95% CI, 0.90-1.31) for BMI 25.0-29.9, 1.25 (95% CI, 0.99-1.57) for BMI 30.0-34.9, and 1.31 (95% CI, 0.97-1.77) for BMI ≥35.0 among those with ≥5 years of follow-up (P

From the perspective of China's urbanization,arable land reform and the bottom line of 18-billion-mu arable land,this article explores the relation of arable land transfer and the bottom line of 18-billion-mu arable land.It argues that arable land transfer can improve the efficiency of arable land use,boost arable land cultivation and safeguard peasants' rights.However,arable land transfer will also bring difficulties in implementing arable land use planning and risks for the forced arable land transfer.Aiming at finding ways to escape from the risks,this article brings forward suggestions for constructing arable land transfer market,strengthening arable land transfer supervision and so on.


This paper briefly presents the results of experimental and analytical investigations on the effect of the temperature on the short and long-term behaviour of two different kinds of structural adhesives used in metal assemblies. Double shear by tension tests were performed on specimens composed of galvanized steel sheets assembled by using epoxy and acrylic adhesives. Two thicknesses of adhesive bondline at four temperatures (-20,0, 20, and 40C) were used for the short-term tests, while one thickness at 40C used for the long-term tests. The investigations showed that increasing temperature adversely affects the used adhesives behaviour, mechanical shear properties, and failure modes. In addition to that, long-term tests showed that a higher temperature can lead to failure in shorter period, even when a joint loaded by constant shear stresses much less than the shortterm ultimate shear strength. Also, it was confirmed that the less the thickness of the adhesive layer, the stiffer the adhesive and the greater the shear strength.

A REVIEW of how nurses prove they are keeping their practice up-to-date is to be launched as part of the government's NHS Plan.


Greek theologians through at least the sixth century tended to be more concerned about the dangers of modalism-usually under the pejorative label of ?Sabellianism"-than they were about subordinationism or even tritheism. Behind all traditions, East and West, lay the real issue of both Trinitarian theology and Christology: how can one understand God as radically one and eternally transcendent with respect to creation, and still understand Jesus as a genuinely divine savior, who genuinely acts in the history as a human being like ourselves? To evaluate the validity of the scheme proposed in this chapter, one needs to move beyond abstraction and to look more deeply into the arguments proposed by a variety of authors in the ancient controversies over God and Christ. The chapter offers three test-cases, in snapshot fashion, from ancient theological debates in which Christological concerns seem to play a determining role in Trinitarian argument, or vice versa. Keywords: Christology; God; Jesus Christ; patristic theology; Trinitarian argument

The Test Template Framework is extended to include capabilities for speciication-based object-oriented testing. The Framework is moved to the object-oriented domain and is extended here to incorporate inheritance and abstract classes. Object-Z is the chosen speciication language that the Framework uses to derive testing information. Some Object-Z features are incorporated into the Framework. Conditions are iden-tiied under which testing information can be inherited without change, when it is inherited with modiications and when it must be derived from scratch. This enables the reuse of test suites by subclasses, alleviating the need for repetitious derivation.


Finite element analysis (FEA) has totally penetrated industry in support of engineered systems design optimization. Over its half century of development, numerous commercial FEA codes have been created to support the distinct engineering disciplines constituting continuum mechanics. Conversely, modern engineering systems design spans multi-disciplines requiring multi-physics analyses of the type supported by COMSOL. As many practicing computational design engineers matriculate without formal academic exposure to the theoretical underpinnings of FEA, familiarity with quantitative assessment protocols for estimating engineering accuracy of multiphysics predictions is weak. The solution to this technical base shortfall is detailed.


The purpose of this study was to comparatively analyze the characteristics of traditional costume colors of Korea China Japan with quantitative methods. The range of this study was limited to the costume colors from 16th to 19th century. For this study 1333 color samples were collected by measuring with a spectrophotometer. The results of this study are as follows: Red, Yellow Red, Yellow and Purple Blue had been used in common for the traditional costume colors of Korea, China and Japan. Yellow of Korea, Purple Blue of China, Yellow Red of Japan showed the high frequency. Red, an asian preference color, had most frequently used in korean traditional costumes. Pale toned Yellow and Yellow Red, high saturated Red and low valued Purple Blue had been preferred for korean traditional costumes. The preferences of high saturated Red and low valued Purple Blue were based on the Five Element theory and the pale toned Yellow and Yellow Red were used with the preference of White and natural colors. In China the traditional costume colors had used with the Five Element theory also but they had preferred Purple Blue, deep & strong toned Red to Yellow Red and Yellow, Yellow Red, Purple and grayish colors had been frequently used in japanese traditional costumes. In the results of color distributions in color space, korean and chinese traditional costumes colors concentrated in some areas like Yellow, Yellow Red, Red and Purple Blue. Japanese costumes colors showed the even distribution with the diverse toned colors. Korean traditional costume colors corresponded with the Five Element theory rather than China and Japan. Japan had used the costume colors with the racial sensibility rather than conceptual color theory.

A saprolegniasis occurred in a group of rainbow trout fingerlings of about 1.2 g in body weight at the Koide branch of the Niigata Prefectural Freshwater Fisheries Experimental Station. The initial sigh of the disease was an appearance of fin rot. Saprolegnia sp. was thought to infect secondarily on the area of fin rot.Six strains of the fungus were isolated from the base of the dorsal fin of 6 diseased fish. Inoculation experiments using moon fish showed that these six strains differed to some extent in pathogenicity from each other (Table 2.). Among the 6 strains strain N7619 was most virulent.All the strains were classified into Saprolegnia sp. according to SPARROW (1960) and DICK (1973) from the characteristics of the asexual organs on hemp seeds. Of the 6 strains, only strain N7619 formed sex organs. In this strain diclinous antheridial branches were predominantly produced, and the oogonial wall were pitted. The type of internal structure of oospores was subcentric. From these structures the strain was identified as S. australis according to SEYMOUR (1970). The characteristics of the sex organs of the strain also agreed with those of S. australis described originally by ELLIOTT (Table 3.).


Long multiple trailer trucks consist of a tractor and two or three semitrailers or trailers that exceed the maximum basic length limitation of 25 meters (82 feet) specified by provincial truck size regulatory schemes in Canada. Over time, the extent and nature of long truck operations have changed due to modifications in the region's highway network, its regulatory environment, and the growing demand to improve regional economic competitiveness. Highway agencies face increasing pressures to permit long truck operations, but currently have limited information to represent or characterize these movements. Understanding the current extent and nature of long truck operations in the Canadian Prairie Region freight transportation system is critical for road design and maintenance, intermodal freight planning, safety analysis, environmental assessment, financing highway infrastructure, economic evaluation, and truck regulation. An algorithm to isolate and classify long multiple trailer trucks is developed. The algorithm utilizes weigh-in-motion data obtained from stations situated on the region's long truck network. The resulting long truck dataset provides the basis for characterizing the volume and weight of long multiple trailer truck movements. The research outcomes service the demand for an understanding of the volume and weight of long truck activity, and provide an analytical basis for forecasting changes in their activity.


Niskanen's theory of government budgeting, involving powerful agencies interested in maximizing their budgets through bargaining with a weak, poorly informed governmental 'Sponsor', has received wide recognition. This paper presents the first direct empirical tests of Niskanen's ideas. One implication of Niskanen's model of budgeting is that the demand for public services will appear to be elastic. Niskanen's model also implies restrictions on the elasticity of the derived demand for labor in the public sector. Neither set of predictions is supported by existing empirical research on government activity.


A survey in 409 undergraduate psychology students was carried out to assess the attitudes and myths of undergraduate psychology students on taking up psychology as a post graduate specialty. The data was collected on a specially prepared self reporting voluntary and anonymous questionnaire and was statistically analyzed. All 409 students answered the entire questionnaire. 399 (97.56%) of students strongly agreed that psychological problems do need to be paid attention. 268 (65.53%) of the participants did not consider the psychiatrist equivalent to other doctors and believed that their job was quite challenging. 200 (48.89%) were open to the idea of choosing psychology as a career. 366 (89.49%) considered psychology a very respectable branch as a career. It was also heartening to note that 236 (57.71%) felt that psychology increased their understanding of other human beings and 377 (92.18%) considered their undergraduate training valuable. Further studies in different settings are needed to corroborate and generalize these findings.

Landraces of wheat (Triticum aestivum L.), collected from the Western Balkans, were considered as a potential genetic resource of drought resistance for wheat breeding. A group of 20 landraces with 80 wheat accessions of worldwide origin were tested in 4-year field trials under two watering regimes: fully irrigated and under a rain-out plot shelter. Fourteen agronomic traits were evaluated for their responses to drought stress, and four selection indices were calculated: mean productivity (MP), stress tolerance (TOL), stress susceptibility index (SSI) and stress tolerance index (STI). The average yield of landraces was significantly lower than that of accessions under both regimes, and there was no evidence that yield stability of landraces was better than that of accessions. However, TOL was better in landraces than in accessions, and several traits related to yield were shown to suffer less under water deficit (i.e. kernels per spike). Amongst landraces, relatively wide diversity (CV 10.2–18.9%) was found for most of the traits that can be exploited for improving drought tolerance of new varieties for the variable rainfed conditions of south-eastern Europe.

Delay and disruption‐tolerant networks are becoming an appealing solution for extending Internet boundaries toward challenged environments where end‐to‐end connectivity cannot be guaranteed. In particular, satellite networks can take advantage of a priori trajectory estimations of nodes to make efficient routing decisions. Despite this knowledge is already used in routing schemes such as contact graph routing, it might derive in congestion problems because of capacity overbooking of forthcoming connections (contacts). In this work, we initially extend contact graph routing to provide enhanced congestion mitigation capabilities by taking advantage of the local traffic information available at each node. However, since satellite networks data generation is generally managed by a mission operation center, a global view of the traffic can also be exploited to further improve the latter scheme. As a result, we present a novel strategy to avoid congestion in predictable delay‐ and disruption‐tolerant network systems by means of individual contact plans. Finally, we evaluate and compare the performance improvement of these mechanisms in a typical low Earth orbit satellite constellation.


BACKGROUND AND PURPOSE: Y-configuration stent-assisted coil embolization is used for treating wide-neck aneurysms. Noninvasive alternatives to x-ray DSA for follow-up after Y-configuration stent-assisted coil embolization treatment are required. This study aimed to assess the usefulness of non–contrast-enhanced MRA by using a Silent Scan (silent MRA) for follow-up after Y-configuration stent-assisted coil embolization for basilar tip aneurysms. MATERIALS AND METHODS: Seven patients treated with Y-configuration stent-assisted coil embolization for basilar tip aneurysms underwent silent MRA, 3D TOF-MRA, and DSA. Silent MRA and 3D TOF-MRA images were obtained during the same scan session on a 3T MR imaging system. Two neuroradiologists independently reviewed both types of MRA images and subjectively scored the flow in the stents on a scale of 1 (not visible) to 5 (nearly equal to DSA) by referring to the latest DSA image as a criterion standard. Furthermore, we evaluated the visualization of the neck remnant. RESULTS: In all patients, the 2 observers gave a higher score for the flow in the stents on silent MRA than on 3D TOF-MRA. The average score ± standard deviation was 4.07 ± 0.70 for silent MRA and 1.93 ± 0.80 (P < .05) for 3D TOF-MRA. Neck remnants were depicted by DSA in 5 patients. In silent MRA, neck remnants were depicted in 5 patients, and visualization was similar to DSA; however, in 3D TOF-MRA, neck remnants were depicted in only 1 patient. CONCLUSIONS: Silent MRA might be useful for follow-up after Y-configuration stent-assisted coil embolization.


Aim. To substantiate approaches to the modeling of the social responsibility of the hospitality industry as a factor of sustainable development of a travel destination.Material and Methods. System analysis theory, economic-statistical method, comparative-descriptive analysis and general scientific methods of empirical research were used to process the initial information and to write the paper. The empirical grounding of the proposed model was based on a survey of the population which had experienced accommodation facilities, on questions about social responsibility and on changes in consumer habits.Results. The authors have identified and characterised the main approaches to modeling social responsibility of the hospitality industry as a factor of sustainable development of a travel destination. A model of corporate social responsibility of a local hotel cluster, which focuses on improving the quality of the hospitality industry, the introduction of energy-efficient and convenient technologies, as well as the development of socio-cultural and tourist infrastructure which contribute to the growth of the social infrastructure of the business, is proposed.Conclusion. The universal nature of the structure of the proposed model, allows the extrapolation of the main results concerning the system of the hospitality industry not only in the Kaliningrad region, but also in other regions of the Russian Federation.


The sum capacity of a multiuser system with interfering multiple input multiple output (MIMO) links is investigated. In an MIMO interfering system, the capacity of each link is a function of covariance matrices of transmit vectors. Therefore, the capacities of the links are mutually dependent and cannot be calculated individually. We consider the sum capacity of the L-user system as the objective function and investigate its convexity with respect to the transmit covariance matrices.


The traditional electromechanical design using two-dimensional drawings conveys information that is relatively abstract, which means simple profiles and elevation drawings can't reflect the three-dimensional effect of the pipeline. And that will cause some problems such as collisions during the construction process, disordered pipeline layout, and unreasonable space utilization. As a three-dimensional design technology, BIM can solve the above problems well. This paper describes the deepening and construction methods of pipe comprehensive based on BIM technology in detail. On the basis of refined modeling, combined with on-site construction experience and the comprehensive layout specifications of various professional pipelines, NAVISWORKS is used for collision detection, which is carried out with the designer and the builder, and the optimization of the original design drawings of the project. The deepened model can be used directly to guide on-site construction, that can reflect the important application value of BIM technology in electromechanical engineering.


A new method for the determination of molybdenum at trace levels has been developed, which is based on the electrochemical reduction of dioxobis(8-quinolinolato)molybdenum(VI). The complex is formed and extracted from the sample matrix into chloroform prior to its reduction at -1.08 V vs. SCE in dimethyl formamide. Only tungsten co-extracts and it does not interfere with the analysis. A linear calibration curve is obtained for the concentration range from 0.1 ..mu..M (9.6 ppB) to 100 ..mu..M (9.6 ppM). The method has been applied to plant samples that have been grown on fly-ash amended soils. 3 figures, 2 tables.

The effect of the relativistic spin rotation on two-particle spin states, conditioned by the setting of the spins of the particles in their rest frames and by the noncommutativity of the Lorentz transformations along noncollinear directions, is discussed. Particularly, the transition from the center-of-mass system (c.m.s.) of two spin-1∕2 particles to the laboratory is considered. When the vectors of the c.m.s. particle velocities are not collinear with the velocity vector of the c.m.s., the angles of the relativistic spin rotation for the two particles are different. As a result, the relative fractions of the singlet and triplet states in the relativistic system of two spin-1∕2 particles with a nonzero vector of relative momentum depend on the concrete frame in which the two-particle system is analyzed.


The article presents a bibliographical and documentary review of Course Preliminary Concept (CPC), considered the official indicator of quality in higher education for undergraduate courses in the country. The survey indicates that CPC underwent several methodological revisions since its creation to optimize the scope assessed. However, the main scientific debate on the topic questions several aspects of this indicator, such as automatic exemption from in-person tests; the development, standardization and weighting of the components; the high participation of students in the final grade; the disregard for the issue of diversity of higher education institutions and existing courses; among others. In this sense, we propose some reflections from a critical perspective in order to understand the weaknesses and potentials of CPC in the quality assessment of higher education courses.


People mostly have difficulty to innovate, to chang e and even change things of their place. The companies are similar. Robbins (20 05) says that organizations, by their nature, are conservative, and therefore it is of i ndividuals, businesses, the role of planning, studying new media and put into practice new ideas and actions called innovations. Innovate is insert news, however, one has to distinguish innovations from improvements or changes. Innovation brings not only means for implementing the same activities, but the application of new ideas and ev en the inclusion of different activities. When innovation is aligned with which the customers expect, and at the same time with what the company has less cost, there is value inno vation. However, to value innovation be deployed, the entrepreneur must be prepared to b reak certain patterns and paradigms and for some time forget the competition to focus o nly the client.

One may expect that the ground state of matter fields depends on the strength of gravity on account of the particle creation by the effect of gravity. In this letter we examine the argument of Hawking from this point of view by considering the shell model. We find that an observer at rest at spatial infinity can 'see' no radiation while an observer at rest near the horizon 'sees' Hawking radiation. Note that the latter thinks that the radiation is to be 'seen' at spatial infinity.


Many pathogenic and genetic diseases are associated with changes in the sequence of particular genes. We describe here a rapid and highly efficient assay for the detection of point mutation. This method is a combination of isothermal rolling circle amplification (RCA) and high sensitive electrochemluminescence (ECL) detection. In the design, a circular template generated by ligation upon the recognition of a point mutation on DNA targets was amplified isothermally by the Phi29 polymerase using a biotinylated primer. The elongation products were hybridized with tris (bipyridine) ruthenium (TBR)-tagged probes and detected in a magnetic bead based ECL platform, indicating the mutation occurrence. P53 was chosen as a model for the identification of this method. The method allowed sensitive determination of the P53 mutation from wild-type and mutant samples. The main advantage of RCA-ECL is that it can be performed under isothermal conditions and avoids the generation of false-positive results. Furthermore, ECL provides a faster, more sensitive, and economical option to currently available electrophoresis-based methods.


The effects of increasing natural gas prices on crop water use and net crop income under alternative crop prices were determined for a 32-county region of the Texas High Plains. An increase in natural gas prices could substantially reduce irrigation over the projection period, based on results from a recursive linear programming model. The price of natural gas, and not the quantity of remaining ground water reserves, may now become the restrictive factor. Irrigation of major corps - based on increasing natural gas prices - is projected to end in 1995 and annual net crop income to fall from $277 million to $164 million.

Whenever I start researching any aspect of what we call "racism," I find myself going back and forth between disciplines, convinced, on the one hand, by those discourses who dismiss the theses of scientific racists ("human races" simply and purely do not exist) but also aware, like many sociologists, anthropologists, or humanities scholars in general that such critical preconditions do not constitute fruitful parameters when the issue is to analyze the relationship between discrimination, inequality, alienation caused by those human races that do not exist. My case study today involves a constant to and fro between literature and politics but also between two supposedly radically different tactics or agendas proposed by one subject who falls into the category of the ethnic minority in France. I am talking about a political figure, who is also a sociologist, an activist, and a novelist who writes autobiographical novels about a child whose Algerian parents had to bring him up in a shanty town and who has, since then, become the "ministre delegue a la promotion de l'egalite des chances" (no mention of "race" here). He was nominated by President Chirac, the head of a clearly right-wing government. What I propose to do today is to connect what may appear to be the two "sides" of Azouz Begag's coin: the work of the novelist, and more specifically a passage from his second novel, Beni ou le paradis prive and the politician's attempt at introducing policies that would promote what he calls "egalite des chances" (equal opportunity) rather than "positive discrimination" although it is clear that he is especially thinking about the youths from the disenfranchised urban areas where he himself grew up. I propose that the relationship between what might appear two distinct discourses is in fact a sort of self-deconstructing double mirror image, each discourse being implicitly critiqued by the other. Their encounter thus constitutes a precious antidote against the temptation of privileging one or the other, the politician or the novelist, the legislator and the storyteller, the Republic and the "I." The tension between the two also highlights the aporias of each set of proposals. Both discourses are part of the solution and part of the problem, and if we systematically endeavor to bring them together, the exercise may teach us the difficult art of allowing two apparently incompatible sets of values to coexist. At least one thing has changed in the past ten years in France: it is no longer safe to assume that it is culturally irrelevant to discuss the issue of racial discrimination. But of course, talking about anything that even involves the concept of human race requires that we pay attention to the historical, ideological or rhetorical constraints, borders within which the concept finds itself confined. The parameters of the debate are already an agenda and what I would like to explore is happening to a conversation in French that has recently included such phrases as "discrimination positive" and "egalite des chances." "Discrimination positive" is not the same as "affirmative action" or even "positive discrimination" and "egalite des chances" is not the same as "equal opportunity." Saying that new ways of imagining the identity of Republican subjects and French citizens are currently displacing the paradigmatic ungendered, racially unmarked and rational abstraction endowed with the same rights and the same Republican duties is a political statement. It allows social actors, including of course politicians but also artists such as writers or filmmakers to map their agreements or disagreements at different nodal points. It used to be relatively easy to distinguish between the so-called "Republicains" and the "communautaristes" who respectively accuse each other of hypocrisy and racism or of threatening the very foundation of the French identity. Today, the points of disagreement are perhaps more productive because they are not so binary. …


The invention discloses a scanning method based on a multi-carrier system. In the method, a service base station of a terminal informs a terminal of carrying out carrier scanning by a scanning message, wherein the scanning message comprises at least one of radio-frequency channel information scanned by the terminal and one or a plurality of carriers needing to be scanned by the terminal. The technical scheme of the invention provides a carrier scanning method based on a multi-carrier system, which enables the terminal to finish scanning on a plurality of carriers of a plurality of base stations in the multi-carrier system and provides a reasonable reference value for carrier switching in and among the base stations of the terminal.


Knowledge transfer can be defined as a process of knowledge creation and application, knowledge mobilization and exchange, information search and transformation as well as the learning process at and outside the workplace. The success of companies in a knowledge-based economy relies more on knowledge and intellectual capital than on other resources. Therefore, transferring new knowledge from foreign multinational corporations (MNC) to the local workforce is a basic step for sustaining competitive advantages. Success in knowledge transfer depends on employee absorption capacities, organizational learning climate, and the willingness of foreign expatriates in MNCs to transfer knowledge. Using the case study of Technology Park Malaysia (TPM), this paper investigates to what extent knowledge inflows and outflows have taken place among the professional Malaysian workforce. It also analyzes the factors influencing knowledge transfer.


Background & Aims : In the recent years, the considerable interest in survivin has significantly increased, because of its possible detection role in esophageal cancer. Materials and Methods: Twenty eight patients diagnosed with esophageal cancer and thirty three healthy controls were assessed for the purpose of the study. From March 2015 until September 2017, the subjects who had esophageal cancer were enrolled in the study. Blood samples were from subjects enrolled in a prospective cohort undergoing annual esophageal cancer testing. The concentrations of serum survivin were determined using Elisa method. Results : Serum levels of survivin in the esophageal patient group increased compared to the healthy controls [164.06±55.03 (mean±SD) vs. 119.37±48.25, ng/L, P<0.04].Elevated serum survivin had positive correlation with clinical parameters . Conclusion : The positive association between elevated serum survivin and esophageal cancer status could be due to the fact that this protein involves in the development of esophageal cancer . Determination of serum survivin could differentiate normal and esophageal cancer subjects and lead to lower numbers of excessive esophageal biopsies.


Almost all context-aware systems have two indispensable components - context provider and context consumer. The former is responsible for supplying diverse context information about users and environments, while the later makes use of context information in building context-aware applications. The diversity of context information from heterogeneous context suppliers to different consumers justifies the need for a generic re-usable middleware to manage context data flow from low-level providers to high-level consumers. As a first step, we propose a declarative quality-aware context middleware specification language. It contains four types of descriptors, namely, point descriptors, connector descriptors, constraint descriptors, and quality descriptors. Through the context middleware specification, context acquisition, integration, and transformation patterns from suppliers to consumers, as well as associated functionality and non-functionality requirements and constraints, can be uniformly declared.


Although rates of bed-form growth for steady flows (Nikora and Hicks 1997), have been clarified, practical implications and models accessible to the engineer remain to be elaborated. For example, how and at what rates bed forms change for increasing and decreasing flows remains to be quantified. There has not been much progress since Julien and Klaassen 1995 in defining a relationship between flow and bed-form characteristics. Sediment transport engineers in the current era have a very good idea of the size and shape of a particular dune at various discharges and sediment types. But very little is known about the time it takes to change the dune when the flow was to experience an increase or decrease. Previous research in this specific area was done by (J.R.L. Allen, 1976) who did an earlier model for dune time-lag in periodically varying unidirectional flows. The research undertook measurements of a river and data over discharge and dune wavelength over the year. This data was then computed on a monthly basis. Model showed that hydrograph shape could substantially influence dune behaviour in unsteady flows. For the same flow period and extreme discharge values, a reduction in the relative duration of the high-water stages causes an increase in the phase differences between dune dimensions and flow, and an increase in the dimensions averaged over the flow cycle as compared with the similarly averaged dimensions given no lag. The relative range of dimensions over the flow cycle is little affected. This research is mainly about how the bed form reacts to the change in flow and specifically the time it requires for a specific bed form to adopt its new bed form in regards to increase/decrease in flow. This research takes an experimental form to develop a stochastic modal for the time required for the change in bed-form morphology in relation to the change in flow. This includes the dune shape and height. The experimental analysis is in a flume with controlled sediment type/density/size, water depth and also the flow rate. The analysis is for the flow in a uni-direction. The depth of the dunes, shape and the velocity of the flow is measured by an ADV, and analyzed later using matlab to include a 3D representation and analysis. Through which the temporal and special changes in bed form due to change in flow is made clear and presented herein.


Wavelet-based data fusion techniques have been used extensively in several application areas, including quantification of flaw parameters in nondestructive evaluation applications. The use of hybrid systems including the use of wavelets and neural networks for fusion and corrosion characterization is relatively recent. While the hybrid approach usually results in fairly accurate results, the selection of the fusion parameters is manually accomplished and is typically a time-consuming process. This paper proposes a multiresolution data fusion algorithm to improve the performance of corrosion quantification in aircraft lap joints. A maximum likelihood estimation scheme is proposed to fuse data in the wavelet domain. The proposed algorithm reduces the dimensionality of the input and improves the robustness of the network. Initial results indicate that the proposed approach gives similar results to those obtained using manual parameter selection, and indicate the feasibility of the algorithm


Objective: We aimed to evaluate work productivity on the quality of life and disease activity in ankylosing spondylitis. Material and methods: One hundred ankylosing spondylitis patients were included in the study. Disease activity was assessed by Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), quality of life was assessed by Ankylosing Spondylitis Quality of Life questionnaire, work productivity was assessed by work productivity and activity impairment questionnaire. Results: Absenteeism, presenteeism, work productivity loss and activity impairment scores were positively correlated with BASDAI. We found correlation between absenteeism, presenteeism, work productivty loss, activity impairment scores and poor quality of life. Conclusion: As a result of our study, work productivity should be considered in clinical practice. Assessment of work productivity in routine clinical practice can contribute to a better understanding of problems in patients' behavior to treatment.


The article presents the experience that is being developed in the outlying neighborhoods with the participation of four educational centers: two Pre-school and Elementary Education centers (CEIP) and two Secondary Education Institutes (IES). Based on the culture as social manifestation, the authors reflect on the school culture and its relationship with school failure, and they analyze the possibilities of community development as a way to approach it. In this experience, the community development process is in its initial stage, and there has been a consolidation of the coordination of the different public and private services and resources that affect the zone. The prevention and promotion job that is going on in the streets, thanks to the "El Patio" process, is complimented by the participation of the educational centers, as well as community use of their installations. They are currently carrying out a community diagnosis in which objective data and statistics are gathered, and the audition process for the subjective part takes place. With the synthesis of these data, a discussion process will be initiated with the entire population towards a community search for alternatives.
