Simulation study of direct current vacuum breakdown and its application to high-gradient accelerating structures
Authors: Radmilovic-Radjenovic Marija , Radjenovic Branislav
Published: July 2020

It is well known that radio frequency breakdown is one of the main
limitations in high frequency accelerators. Similarities have been detected
between breakdowns in direct current vacuum gaps and those in superconducting
radio frequency cavities. Therefore, cavity break- downs due to electric
field phenomena can be understood by studying direct current vacuum
breakdowns. Significant irregularity of a surface and a variety of involved
processes objectively stipulate a number of factors which may lead to a
breakdown. In this paper, the effects of surface conditions, accelerator
gradient, pulse length, and operating frequency on the breakdown have been
studied by using COMSOL simulation package. It was found that the dependence
of breakdown rate on accelerating gradient and pulse length follows scaling
laws. Based on the time evolutions of electron density and the potential in
cone-cylinder electrode configuration at the pressure of 0.1 Pa, the time
scale of a vacuum breakdown has been established. It was also confirmed that
the emission from an electrode surface can be regarded as a major factor
leading to electrical breakdown in vacuum. The obtained results could be very
useful in high-gradient accelerating structures.
Microstructure and mechanical properties of MWCNT/Ti6Al4V composites consolidated by vacuum sintering
Authors: Phuong Doan , Van Duong , Ngoc Nguyen , Van Pham
Published: July 2020

Ti6Al4V alloys with low weight, high corrosion resistance, high melting
point, high biocompatibility and unique mechanical properties have been
receiving great attention for wide applicability in many industry fields
such as automobiles, aerospace and biomedical. However, Ti6Al4V tends to be
easily oxidized at high temperature, exhibit low thermal conductivity, low
hardness and low yield strength and thus have led to the limitation of
applicability in many industries. In this study, we have fabricated Ti6Al4V
matrix composites reinforced with multi-walled carbon nanotubes (MWCNT) to
enhance the hardness and yield strength. Vacuum sintering technique has been
used to prepare MWCNT/Ti6Al4V composites. Microstructural and phase studies
indicated that the composite structure consists of two main phases including
?-Ti and ?-Ti and MWCNTs were uniformly dispersed in Ti6Al4V matrix. The
relative density of composite decreases as the CNT content increases as
resulted from the porous structure of the CNT, which limits the aggregation
process of the composite. When the CNT content increased, the hardness and
yield strength of the composite increased, reaching maximum values of 378 HV
and 356 MPa with 2 vol.% MWCNTs, which are nearly 16 and 38% higher than
those of Ti6Al4V alloy. The enhancement in hardness and compressive strength
is attributed to the good mechanical properties of MWCNTs and load transfer
effect from Ti6Al4V alloy matrix to reinforcement material.
An Overview of Academic Tax Accounting Research Drawing on U.S. Multinational Taxation
Authors: Shevlin Terry
Published: July 2020

Economics-based tax research in accounting draws heavily on the Scholes-Wolfson framework. The framework develops a global approach to tax planning where all parties, all taxes, and all costs are to be considered in effective tax planning. Effective tax planning is distinct from tax minimization as the goal of the former is to maximize the after-tax rate of return. The first empirical applications of the framework followed the passage of the Tax Reform Act of 1986. Taxation of multinationals has long been of interest to accounting (and other) researchers and continues to be of interest. The Tax Cuts and Jobs Act of 2017 changed many tax laws including how the U.S. taxes U.S. multinationals. Research examining the ramifications of this latest Tax Act is already well under way.
A Systematic Review of Contract Farming, and its Impact on Broiler Producers in Lebanon
Authors: Kozhaya Rodrique
Published: July 2020

This Thesis has been realized within the agribusiness sector and experiments the Transaction Cost Theory a branch of the New Institutional Economy which explain market failure caused by many factors. Transaction costs are associated with carrying a transaction between buyers and sellers. This study has been conducted between 2014 and 2017; and has collected data from 11 broiler producers in Jezzine, Lebanon, about: Production costs, capital investment, revenues, land tenure, access to infrastructure, and information about the contract. The propensity score matching method is used to compare the effect of participating in contract farming and to solve the hypotheses, which say: There is a positive relationship between contract farming and the economic benefits of broiler producers and the development of the broiler sector in Jezzine District. Findings from farmer’s interviews indicated that sustainability, guaranteed price, risk reduction, credit facilities and technical aids are the main reasons for signing a contract. In contrast, Farmers have expressed problems concerning the contractors’ responsibilities such as delay in payment and delivery. Also, when prices are high, it was argued that farmers were selling the products in the open market.
A Longitudinal Study of the Turkish Marketing Academia: What Has Changed and What Has Not in a Decade?
Authors: Erdoğan B. Zafer , Doğan Semra , İşlek M. Sami
Published: July 2020

This article compares the findings of two surveys of the Turkish marketing academia undertaken in 2007 and in 2016. As a follow up replicating Erdogan and Uzkurt's study (2007), this 2016 study aims to reveal the current status and problems of the marketing academia in Turkey as an emerging country, by adding a longitudinal dimension. The same questionnaire was used for both surveys carried out. The data collection procedure included both an online survey and a drop-and-collect survey, with the participation of faculty members with all types of academic titles working in the Turkish marketing academia. 108 and 132 usable questionnaires were collected in 2007 and 2016, respectively. The research findings indicate that the problems experienced have remained fairly similar in almost all dimensions, while the publication performance has increased during this period. The findings about research and teaching interests indicate that marketing academics primarily concentrate on such fields as consumer behavior, marketing research and marketing strategy. The teaching and research interests have also differed depending on global trends and changes in tenure standards in the Turkish marketing academia. Another key finding regarding the issues of the field, with vital implications for marketing education, is the perceived gap between marketing theory and practice. The fundamental issue related to education is cited as the decreasing student proficiency in Turkey.

Published: July 2020

The formation and development of an entrepreneurial structure is currently one of the prior-ity areas for the development of the country's economy. The adopted project for the imple-mentation of the project “Small and Medium Enterprises and the Support of Individual En-trepreneurs” contains a list of measures aimed at developing small and medium enterprises in the country. The development of the project and its implementation do not guarantee the desired result. Monitoring the progress of the project should be systematic and comprehen-sive. The purpose of this study is to analyze the intermediate results of the implementation of the national project in the field of entrepreneurship development, to identify the weak-nesses of this process. To obtain an objective assessment of the level of entrepreneurship development, we used two groups of statistical data: world indicators estimated by the World Bank, as well as national data presented in Russia and the Federal Tax Service of the Russian Federation. This approach is aimed at implementing the basic principles of economic analysis: objectivity, reliability, complexity of research. We evaluated the effective-ness of the development of enterprises, as well as the position of research on internal pro-cesses taking place in the process of project implementation. We proposed to calculate a composite index for assessing the effectiveness of the system of state support for entrepre-neurship in the regions. The scientific relevance of the research is to provide support for entrepreneurship in the country. It was established that the development of decisions should be accompanied by a detailed analysis. Recommendations are also given regarding the need to clarify the basic concepts and methods for calculating targets to achieve compara-ble data. There were used retrospective analysis, statistical analysis and index method for evaluating indicators.
THE OPPORTUNITIES OF MEASUREMENT OF INSTITUTIONS AND INSTITUTIONAL CHANGES
IN MODERN ECONOMIC SCIENCE
Authors: Tanenkova Ekaterina N.
Published: July 2020

The article provides an overview of various approaches and methods for measuring

institutions and institutional changes. The measurement of institutions refers to the measurement of their effectiveness, quality, and performance by modeling, evaluating, and interpreting

the institutional environment or individual institutions, taking into account the distribution of

roles among economic actors, their goals, and possible collective and individual actions within

these institutions. There are two main approaches to measuring institutions: direct and indirect.

The indirect approach includes methods that measure institutions through the assessment of

institutional effects, which are expressed in changes in micro – and macro-economic parameters, indicators, indicators, and equilibrium states. The methods of the indirect approach include

indicative, based on macroeconomic proxy indicators; game-theoretic, which defines institutions as the results of game equilibria; and microeconomic, which tools are usually neoclassical models. Analysis of the capabilities of modeling and measuring institutions using these

methods revealed certain disadvantages and difficulties in using indirect methods. It seems

that the most interesting tool from the point of view of modeling can be the use of the contract

method, in accordance with which direct modeling of microinstitutions – contracts takes place.

The measurement of institutions using contract models requires further research, namely the

development and inclusion in the models of certain institutional characteristics that can be

interpreted as "direct" criteria for institutional measurements. The contract method in the future

can create conditions for the development of models of institutional measurements of both

qualitative and quantitative order.

Theoretical provisions and conclusions relate to the structural content of technical and technological development through the relationship with the conditions for the development of the technical and technological base. There are given the main elements of technical and technological equipment that can be measured and focused on the growth of the technological level of production. It is shown that the prospects for technical and technological equipment lie in the development of knowledge-intensive means of labor, the level of fundamental scientific and technical research, as well as technological integration of related processes. The stable dynamics of resource provision in the form of capital injections into technological re-equipment and modernization of production in the Russian and Western economies are revealed. The article offers a synthesis of innovative approaches to the technical and technological development of enterprises with the designation of special areas of the production process by technologization, structuring mechanisms of diagnostics data to inform management decisions, outsourcing services, corporate governance and the taxation of transnational associations. The article reveals the prospects for establishing relationships between industrial enterprises and financial structures based on the principle of supply chain financing. Further studies of technologization include the digitalization of production, knowledge economy, as well as schemes of platform cooperation between industrial companies and stakeholders. It is emphasized that the technical and technological equipment of enterprises has a high degree of dependence on the state of the resource base, which should be regulated taking into account deviations from the course of sustainable development.

Published: July 2020

Within the framework of the article, the role of a po-litical actor is attributed to the Collective Security Treaty Organization (hereinafter – CSTO) as a special political-military association. This study is looking for answers to a number of questions, such as what the political positioning of CSTO at this stage is, how it is evolving and what image CSTO is projecting. The author also questions whether the subject of politics perceived as a "shield of the Commonwealth", a variation of "post-Soviet NATO", a "donor of regional security", a "part of a Eurasian structure of collective defense", an intergovernmen-tal international organization or something else. In order to answer these questions, relevant materials, placed on official online portals of the Heads of CSTO member-states starting from the year 2018 (when the “Velvet Revolution” happened and the process of substituting the CSTO Secretary-General Yuri Khachaturov on charges of overthrowing the constitutional order in Armenia started) to June 2020, are being analyzed. Through the analysis of utterances and official statements by the heads of CSTO member-states regarding this Organization, features of its political positioning and image are being identified. Discourse analysis and content analysis are used as research methods.

One of the key issues of Human Resource Management is the motivation of employees in continuing education, especially in times of economic crisis such as the one Greece is experiencing today. Investing in continuing training is crucial because it can boost economic and competitive performance at an individual, organizational and social level. The aim of this literature review is to present and understand the factors motivating individuals and, in particular, healthcare professionals for Continuing Education with the primary aim of maximizing their effectiveness and efficiency. A review of the literature was carried out on the basis of research and review studies drawn from international (Medline, PubMed) and Greek (IATROTEK) databases. According to the literature, the predominant motivational factors were acquiring new knowledge, maintaining and improving skills, professional development and improvement, health promotion, professional self-knowledge and empowerment, interaction with colleagues and the rise of professional prestige. Lack of time, economic reasons, overworking and family obligations are the main obstacles to participation in continuing education. In a period of protracted economic downturn, the health sector faces the problem of limited budgetary resources while at the same time the demands for more effective and efficient services are increased. Taking into account the incentives that drive health professionals towards the CE, training strategies are planned and implemented which have as their pillar and orientation the specialized training needs of the employees with the ultimate benefit of improving the health services provided while meeting the increased needs and the expectations of society as a whole.

Kenaf (Hibiscus cannabinus L.) is a fiber crop classified in the genus Hibiscus (Malvaceae), and has a great potential for its multipurpose utilization, in addition to its traditional usage. Varietal identification of kenaf is always problematic and knowledge on genetic variability of kenaf varieties is also limited, which significantly hindered our effective utilization and conservation of the valuable kenaf germplasm. In order to find a proper method for identifying kenaf varieties and studying their variation, morpho-agronomic characters were analyzed. Fifty eight accessions of kenaf germplasm collected from Gene Bank Department of Bangladesh Jute Research Institute were characterized at Jute Agriculture Experiment Station, Manikganj during April 2014 to December 2014. The accessions were characterized for fifteen morpho-agronomic attributes as per Hibiscus descriptor in order to select superior genotypes for the genetic improvement of kenaf. Considerable ranges of variability were observed in stem colour, petiole colour, plant height, base diameter, dry fibre weight, dry core weight, green weight with leaves and green weight without leaves. Based on major yield contributing characters accessions 1653, 3384, 3928 and 4202 performed better than the control varieties HC-2 and HC-95.

Existem diferentes atividades de treino que o treinador pode optar para o desenvolvimento da finalização na iniciação ao futsal. Contudo, são escassos os estudos que, de fato, trazem informações científicas que possam subsidiar o treinador a fazer as melhores escolhas. Diante do exposto, o presente estudo teve como objetivo comparar diferentes atividades de treino para o desenvolvimento da finalização na iniciação ao futsal. Participaram do estudo 23 jogadores de 8 a 11 anos de uma escola de futsal do noroeste do Paraná. Foram avaliadas as atividades: a) jogo formal, b) jogo reduzido, c) gol a gol e d) chute a gol. Os resultados apontam que, o “gol a gol” é a atividade que proporciona a maior média de finalização. Por outro lado, foi na atividade de chute a gol em que se observou o maior percentual de acertos das finalizações e menor diferença na frequência de chutes com a perna dominante e não dominante. Por fim, foi observado que nenhuma das atividades proporcionou exercitação suficiente da finalização com outras partes do corpo.
Evaluación de la estructura comunitaria de las esponjas marinas en parches arrecifales del Caribe sur, Costa Rica
Authors: Araya-Vargas Alexander , Busutil Linnet , García-Rojas Andrea , Pereira Chaves José Miguel , Piedra-Castro Liliana
Published: July 2020

Las esponjas marinas cumplen un gran número de funciones críticas para los arrecifes coralinos. A su vez, las variaciones en la estructura comunitaria de los poríferos pueden indicar cambios en las condiciones ambientales de los ecosistemas donde habitan. Sin embargo, su estudio ha sido escaso en el Caribe de Costa Rica, principalmente en el ámbito ecológico. Por tanto, se evaluó la estructura comunitaria de estos organismos en cuatro parches arrecifales (Perezoso, Pequeño, Coral Garden y el 0,36) y se determinó si podía ser explicada por la sedimentación, el sustrato y la profundidad. Se calculó la abundancia relativa (AR) y la cobertura relativa (CR) para cada especie, la densidad de esponjas e índices de diversidad (riqueza de especies, heterogeneidad de Shannon, equitatividad de Pielou y dominancia de Simpson) para cada sitio de muestreo. Se comparó la similitud entre sitios respecto a las abundancias relativas de esponjas versus sedimentación, sustrato y profundidad. Se encontraron 13 nuevos registros de esponjas para el país. Perezoso presentó la mayor cobertura de esponjas (CR = 6,1 %) compuesta principalmente por Cliona caribbaea (CR = 2,0 %) y con Niphates erecta como especie dominante (AR = 59,3 %). La riqueza de especies aumentó a medida que aumentaba la profundidad en los sitios. Perezoso y Coral Garden mostraron la mayor similitud en cuanto a la abundancia de especies y compartieron a N. erecta, Iotrochota birotulata y Scopalina ruetzleri como las especies más abundantes. Asimismo, compartieron las mayores frecuencias de aparición (40 %) de esponjas perforadoras del género Siphonodictyon y la presencia de la especie bioerosionadora C. caribbaea. La similitud entre Perezoso y Coral Garden podría estar influenciada en mayor medida por la alta disponibilidad de pavimento calcáreo como sustrato predominante (48 < PC % < 67), el cual parece favorecer la abundancia de esponjas heterotróficas y generalistas, así como la de especies perforadoras y bioerosionadoras.
Colonización a largo plazo de corales por una esponja excavadora del Caribe
Authors: Marulanda-Gómez Ángela , López-Victoria Mateo , Zea Sven
Published: July 2020

Las ramas muertas de Acropora palmata colonizadas por la esponja excavadora Cliona tenuis son propensas al desplazamiento, la rotura y la translocación durante fuerte oleaje o mar de fondo de tormentas o huracanes, lo que favorece la dispersión de esta esponja. En las islas del Rosario (Colombia, Caribe), los adultos de C. tenuis transportados por fragmentos de A. palmata que cayeron sobre corales masivos vivos colonizaron el nuevo coral y mataron posteriormente el tejido vivo del coral recién invadido. Los corales que reclutaron sobre las ramas caídas de A. palmata cubiertas de C. tenuis también fueron invadidos una vez que la esponja llegó a su base. Para determinar si la incidencia de este fenómeno aumentó desde 2002, cuando se documentó por primera vez, la prevalencia y el modo de colonización de corales por C. tenuis se cuantificó nuevamente en 2014, en el mismo arrecife. Aunque es difícil inferir una tendencia a partir de dos muestreos puntuales, el número de colonias de coral colonizadas por C. tenuis se duplicó en 2014 y se encontraron nuevos casos de colonización desde ramas de A. palmata portadoras de esponjas. Sin embargo, la frecuencia de colonización por esponjas adultas desde las ramas de A. palmata en 2014 fue entre la mitad y un quinto menor que en 2002, lo que sugiere que otras formas de colonización en corales masivos pueden estar aumentando o que las tormentas borran la evidencia de adultos colonizadores por la translocación de las ramas de coral que han servido de vectores, como se observó en un caso monitoreado. A medida que pasa el tiempo y aumenta la fragmentación y la erosión del arrecife, la evidencia de colonización de corales pétreos por C. tenuis a través de las ramas de A. palmata se desvanece.

Este estudio presenta la densidad, composición taxonómica, distribución espacial y temporal de larvas de peces en el golfo de Guayaquil, así como la relación con algunas variables físico-químicas. Se recolectaron muestras en 16 estaciones, tomadas en la primera milla náutica del estuario externo e interior del golfo, ubicadas frente a la provincia de Guayas y noroeste de la isla Puná, durante junio a diciembre de 2012. Se realizaron arrastres superficiales con una red cónica simple (ojo de malla: 300 μm; diámetro de boca: 0,3 m; largo: 1,2 m). La temperatura, salinidad y transparencia fueron medidas antes de cada arrastre. Se detectaron diferencias significativas entre zonas, registrando mayor temperatura, menor salinidad y transparencia en el estuario interior. Se colectaron 321 638 ind/100m3 de larvas de peces, pertenecientes a 13 familias y 36 especies entre la zona externa e interna. Engraulidae (58,9 %) fue la familia más abundante en las estaciones del estuario exterior, seguida de Sciaenidae (22,8 %) y Haemulidae (9,6 %). Las familias más frecuentes en el estuario interior fueron Engraulidae (74,4 %) y Gobiidae (16,1 %). El 85 % de la densidad total fue aportada por cinco especies, de las cuales Anchoa sp. y Bairdiella sp. fueron las más abundantes y dominantes, principalmente durante diciembre. La estructura y composición de la comunidad larvaria fue significativamente diferentes entre áreas (MW-U= 450; p < 0,05) y meses de muestreo (KW=14,24; p < 0,05), con mayores registros en el estuario exterior durante diciembre. Con el análisis de redundancia (ADR) se observa que, en el área externa, las especies estuvieron asociadas con la transparencia del agua, mientras que las especies que concurrieron en la zona interna se relacionaron positivamente con la salinidad. En términos generales, la abundancia y riqueza de larvas de peces en el área externa del golfo de Guayaquil está relacionada con las condiciones de transparencia y salinidad local, las cuales favorecieron a la presencia larval.

The article considers the results of study of current trends in the innovative activities of 15 national libraries of the Commonwealth of Independent States (CIS). In research, the author applied the methods of polling, comparative analysis, expert review, analysis of websites and printed sources in order to detect the promising areas for international library cooperation and partnership in the CIS. The author underlines the relevance of this research connected with the need to analyse the strategies of the CIS national libraries developed up to date. The article presents information on technology innovation, changing processes and reconfiguring products and services, as well as on organizational and management advanced innovation. The core programs of all national libraries of the CIS countries are focusing on e-library development, including coordination activities on the creation of national electronic libraries in the countries, full-text databases, as well as projects promoting international academic movement Open Access. The article presents the studies on scientific description and creation of soft copies of the unique national documentary monuments, as well as development of information portals and websites. Organizational and management innovation of national libraries of the CIS countries focuses on structural changes. These transformations promote creation of virtual reading rooms, electronic resource rooms, book and book-printing museums, as well as educational projects — training centres, including distance learning centres, and schools for conservation and restoration of manuscripts. Based on the analysis of empirical data, the author concludes that the priority innovative projects of national libraries cooperation are focused on provision of remote access to the most complete volume of document collections available in the CIS countries; these projects increase satisfaction of the needs of users of national libraries and the whole population in the relevant information.

Endowed with a multitude of exquisite properties such as rich electrochemistry, superb topology and eccentric electromagnetic phenomena, honeycomb layered oxides have risen to the top echelons of science with applications in diverse fields ranging from condensed matter physics, solid-state chemistry, materials science, solid-state ionics to electrochemistry. Although these features are known to stem from the utilitarian structure innate in these oxides, their functionalities are vastly underutilised as their underlying atomistic mechanisms remain unknown. Therefore in this study, atomic resolution imaging on pristine K2Ni2TeO6 along multiple zone axes were conducted using spherical aberration-corrected scanning transmission electron microscopy (Cs-corrected STEM) to reveal hitherto unreported topological defects and curvature which can be associated with various phase transitions. Furthermore we discover, for the first time, the occurrence of a new stacking variant with P3-type sequence alongside the well-reported P2-type stacking domains. Through this work, we provide insights into the connection between these unique structural disorders to the electrochemical properties of honeycomb layered oxides. The mechanism of the phase transitions reported herein is bound to become apparent upon high alkali-ion mobility, providing invaluable clues to potentially improve their functional performance in, for instance, energy storage applications. Our findings have the potential to inspire further experimental and theoretical studies into the role of stacking and topology in honeycomb layered oxides.
BioMetAll: Identifying Metal-Binding Sites in Proteins from Backbone Preorganization

With a large amount of research dedicated to decoding how metallic species bind to protein, in silico methods are interesting allies for experimental procedures. To date, computational predictors mostly work by identifying the best possible sequence or structural match of the target protein with metal binding templates. These approaches are fundamentally focused on the first coordination sphere of the metal. Here, we present the BioMetAll predictor that is based on a different postulate: the formation of a potential metal-binding site is related to the geometric organization of the protein backbone. We first report the set of convenient geometric descriptors of the backbone needed for the algorithm and their parametrization from a statistical analysis. Then, the successful benchmark of BioMetAll on a set of more than 50 metal-binding X-Ray structures is presented. Because BioMetAll allows structural predictions regardless of the exact geometry of the side chains, it appears extremely valuable for systems which structures (either experimental or theoretical) are not optimal for metal binding sites. We report here its application on three different challenging cases i) the modulation of metal-binding sites during conformational transition in human serum albumin, ii) the identification of possible routes of metal migration in hemocyanins, and iii) the prediction of mutations to generate convenient metal-binding sites for de novo biocatalysts. This study shows that BioMetAll offers a versatile platform for numerous fields of research at the interface between inorganic chemistry and biology, and allows to highlight the role of the preorganization of the protein backbone as a marker for metal binding.
