Background

Current evidence indicates that vascular calcification plays an essential role in the development of cardiovascular diseases in end-stage renal disease (ESRD) patients. Arterial stiffness is a marker of increased cardiovascular risk in various populations. The aim of this study is to evaluate the elastic properties of ascending aorta in patients with ESRD.

Methods

This single-center study enrolled 96 patients (45 females, age: 57.2 ± 12.8 years) with ESRD and 96 healthy controls (52 females, age: 55.3 ± 10.1 years). Aortic pressures and aortic elastic parameters including aortic strain, aortic distensibility, aortic stiffness index, and aortic compliance were calculated using accepted formulae.

Results

The hemodynamic parameters including aortic pulse pressure, aortic mean pressure, aortic fractional pulse pressure, and aortic pulsatility index were significantly higher in patients with ESRD. Systolic and diastolic aortic diameters were similar between the groups. However, pulsatile aortic diameter change, aortic strain, aortic distensibility, and aortic compliance were significantly lower, whereas aortic stiffness index was significantly higher in ESRD group.

Conclusions

The results demonstrated that a significant difference was present in terms of aortic blood pressures between patients with ESRD and controls. In addition, the elastic properties of ascending aorta were decreased in patients with ESRD.
Corpos (Não) Controlados: Efeitos dos Discursos sobre Sexualidades em uma Escola Médica Brasileira

RESUMO As conquistas dos movimentos de lésbicas, gays, bissexuais, travestis e transexuais (LGBT) estabeleceram uma tensão na sociedade que sugere serem irreversíveis suas conquistas, inclusive em termos de visibilidade e recusa ao silenciamento. O cenário de redemocratização e a luta contra o preconceito e a discriminação, assim como pelos direitos humanos e acesso à saúde para todos, compõem alguns dos objetivos desses movimentos. Entretanto, a ideia ainda recorrente da impureza da homossexualidade, que posiciona o sujeito gay como “ser perigoso” reatualiza o estigma e a discriminação com base na suposta “contaminação presumida” do HIV/aids. Nesse sentido, o presente artigo tem por objetivo analisar os efeitos dos discursos sobre as (homo)sexualidades e o HIV/aids na formação médica. Por meio da autoetnografia performática, foi desenvolvida uma análise nas intersecções do self nos coletivos, do eu nas culturas, do agente nas agências, a partir de cenas (auto)etnográficas e da observação participante nos vários cenários de ensino-aprendizagem de uma escola médica pública brasileira. Observamos que, embora proscrito desde a CID 10, o diagnóstico de “homossexualismo” segue sendo produzido e produzindo efeitos por meio da solicitação sistemática e sem evidências de investigação do HIV/aids na formação médica. Assim, compreendemos que ainda há certa cultura hegemônica heterossexual-homofóbica na formação e no cuidado em saúde que atualiza o circuito da exclusão, dominação, colonização e subjugação do sujeito homossexual pela reiterada relação “ser gay – ter HIV/aids”. Com os encontros e as experiências vividas aqui analisadas, explicitam-se visceralmente as disputas e os enfrentamentos no currículo, na esfera do cotidiano e em nossa própria consciência e prática diária para a produção de espaços que considerem outras possibilidades de existência para além da somente hegemônica heterossexualidade branca masculina. Concluímos, também, que foram e ainda continuam sendo abertas várias disputas na formação e atuação médicas, evidenciando que “não estamos sozinhos”. Muitos(as) de nós estamos comprometidos(as) com a tentativa de construir outros modos de ensinar e cuidar, guiados por performances – escritas e corporificadas – de inclusão e resistência, cujo objetivo é expor, desafiar e transformar narrativas desumanas contra a população LGBT e a opressão em geral.

Published: May 2019

RESUMO O Team-Based Learning (TBL) é uma estratégia educacional baseada em aprendizagem ativa que se tornou uma proposta pedagógica alternativa importante no contexto dos métodos de ensino utilizados em educação médica. A proposta do presente trabalho foi avaliar a percepção dos alunos sobre o uso da metodologia TBL em curso de graduação em Medicina e analisar os diferentes aspectos da aplicação desse método de ensino em relação à forma tradicional de ensino utilizada na maior parte dos cursos de Medicina no País. Foi aplicado um questionário específico aos alunos com oito questões e respostas dicotomizadas (escala de Likert com cinco itens). Durante o mês de junho de 2017, alunos do curso de graduação em Medicina (quarto e sétimo períodos) foram submetidos a várias sessões de ensino com o método TBL na Universidade Municipal de São Caetano do Sul (USCS) com os temas sepse, trauma, leucemia, câncer colorretal e câncer de pulmão. A amostra foi calculada em 193 participantes, considerando uma precisão relativa de 10% e um nível de significância de 5% para uma estimativa de 70% de respostas positivas (concordo e concordo firmemente) para a afirmação “Esse TBL teve um impacto positivo no meu aprendizado”. A análise foi realizada com cálculo de estatística descritiva e das frequências relativas e absolutas de respostas com intervalo de confiança de 95% para cada ponto estimado. A utilização do método foi percebida como favorável nos aspectos de preferência (em relação à aula expositiva tradicional), motivação, satisfação e aprendizado. O TBL se destacou como um método pedagógico excelente para a aprendizagem em alunos do curso de Medicina. Uma das vantagens foi a capacidade de desenvolver habilidades em raciocínio clínico e a possibilidade de construir o conhecimento com sua utilização prática. O método ativo apareceu, dessa forma, como uma importante alternativa de metodologia se comparada ao método tradicional.

RESUMO O objetivo deste trabalho é descrever as expectativas dos estudantes de Medicina quanto à carreira profissional. Foi realizado um estudo transversal, descritivo e analítico, no período de janeiro de 2014 a dezembro de 2017, com 116 estudantes concluintes em 2014, 116 de 2015, 91 de 2016 e 110 de 2017, totalizando uma amostra de 431 sujeitos. Foi aplicado um questionário para obtenção de informações sobre idade, gênero, ano de formatura, desejos de atuação profissional para os dez anos seguintes, a especialidade que deseja seguir, o nível de atenção no qual deseja trabalhar, a renda a ser alcançada, o número de empregos que acha necessário para alcançá-la e o número de empregos que pretende ter. O estudo demonstrou predomínio de homens (58,7%), e a média de idade foi de 26,4 ± 3,91 anos. Entre as especialidades pretendidas pelos egressos, Clínica Médica foi a mais almejada em todos os anos estudados, exceto no ano de 2016, em que predominou Pediatria. Sobre os desejos profissionais para dez anos após a formação, a docência foi almejada por cerca da metade deles, variando entre 46% e 59%, enquanto a quase totalidade da amostra demonstrou o desejo de trabalhar com assistência (atendimento direto ao paciente). Não houve predomínio entre as atividades ambulatorial/consultório e hospitalar, assim como entre o setor público e o privado. Em relação ao desejo de atuar nos diferentes níveis de atenção à saúde, os formandos de 2014 e 2016 expressaram desejo de atuar predominantemente no nível terciário (40,5 ± 29,3% e 41,1 ± 29,7%, respectivamente) em relação aos demais níveis de atenção. Sobre a pretensão de renda salarial, predominou a faixa acima de dez salários mínimos, sendo que a maioria expressou achar necessários pelo menos três empregos para alcançá-la, embora o desejo da maior parte dos estudados tenha sido manter apenas dois empregos. Conclui-se que as chamadas áreas básicas, como Clínica Médica, Cirurgia Geral e Pediatria, ainda são bastante almejadas pelos formandos. Contudo, mais do que o desejo de segui-las, provavelmente isto representa a necessidade de pré-requisito para acesso a outras especialidades. No geral, os egressos pretendem trabalhar com assistência, têm uma expectativa salarial alta, admitem a necessidade de diversos vínculos empregatícios para atingir esta meta e têm pouco interesse em trabalhar no nível primário de atenção à saúde. Tal realidade poderia ser discutida no âmbito da academia, a fim de oferecer informações realistas aos estudantes sobre o mercado de trabalho e a carreira médica, minimizando frustrações futuras durante o exercício profissional.

Published: May 2019

Resumo O artigo propõe perspectivas integradoras entre teoria e prática no trabalho da pesquisa, voltadas para a superação de uma abordagem dualista. Observa o interesse da proposta para ciências humanas e sociais, assinalando, entretanto, uma relevância especial para a área da comunicação. Depois de caracterizar sumariamente atividade prática, o texto desenvolve reflexões sobre três âmbitos em que fazeres práticos são estruturantes para a teoria: ações requeridas para sua própria gênese; a elaboração expositiva, que ao mesmo tempo constrói e faz circular a teoria; e a realização da teoria por seu acionamento a serviço da pesquisa. O artigo mostra, nesse acionamento, doze ações possíveis. A conclusão explicita a íntima articulação entre aqueles três momentos.

Narrative and database in “All that is Solid”, a desktop documentary
Authors: Magno Sara
Published: May 2019

Abstract This paper proposes to analyze “All that is Solid” by artist and filmmaker Louis Henderson, a documentary film that uses the desktop of the computer as a background for a new kind of narrative structure to unfold. This film will be looked at mainly through Lev Manovich´s notion of the “database as a symbolic form” (MANOVICH, 1999) which the author attributes to the “age of the computer” when the database becomes the key form of cultural expression after the novel and cinema. It conducts a close reading of the film while pointing out several moments when database as a cultural expression surfaces, becomes dominant, and competes with conventional narrative forms of filmmaking. Through the basic system of organizing folders on his computer’s desktop Henderson reflexively unravels a complex story: as technological progress advances in the West, piles of obsolete computers are thrown away, sent to the coast of West Africa, and end up being recycled in waste grounds such as Agbogbloshie in Accra, Ghana. The film confronts us with a strange system of recycling, a kind of reverse, neo-colonial mining, where groups of Ghanaians search for residues of mineral resources in the computer waste materials sent from Europe. It tells us of the correlation between technology and race, and of the immateriality of the ‘Cloud’ in contrast to the heavy materiality of e-waste zones.

Published: May 2019

SUMMARY This studyaimed to assess the influence of three pre-grazing heights of Massai grass on the ingestive behavior of sheep under rotational stocking. Eighteen Dorper x nondescript crossbred sheep were used under rotational stocking on Massai grass at pre-grazing heights. The animal stocking was estimated to ensure a reduction of approximately 50% of the initial height. Behavior assessments were performed from 6 to 18 h at the entrance and exit of animals from paddocks. The longest activity was grazing, followed by rumination and other activities, and the period from 6 to 10 h showed the longest grazing.In the other periods, the animals in the 35-cm treatment grazed less when compared to those ofthe other treatments. Rumination in all treatments was more significant in the period from 14 to 18 h, but the animals in the 45-cm treatment spent more time doing this activity, which gave them a higher time of rumination of the food bolus, as well as ruminating chews. The bite rate was higher for the 25-cm treatment, followed by the 45 and 35-cm treatments, respectively.
Regression modelling on wear behaviour of nano fly ash–aluminium alloy matrix composites
Authors: Katrenipadu Srinivasa Prasad , Gurugubelli Swami Naidu
Published: May 2019

The demand for particle-reinforced composites has been increasing progressively. Hence, there is an exigency to use low-cost particles or solid waste particles as a reinforcement phase in order to reduce the cost of the composite. Fly ash is a solid waste consisting of various oxides such as silicon dioxide (SiO2), aluminium oxide (Al2O3) and iron (III) oxide (Fe2O3), which will contribute to improving wear resistance. Hence, an attempt is made to use nanostructured fly ash as particle reinforcement to produce high-wear-resistance composite materials. Microsized fly ash was converted to nanostructured material by high-energy ball milling, and the crystallite size was reduced to 27 nm after 30 h of milling. The influence of applied load, sliding speed, sliding time and fly ash reinforcement on dry sliding wear of the metal matrix composites is determined. Wear resistance was increased with increase in fly ash fraction, and beyond 10 wt%, it was decreased. The increased frictional thrust at higher load results in increased debonding and wear rate. The regression model was developed by using the statistical software Minitab R17.1.0 to predict the wear behaviour of the composites under conditions of different normal loads and time periods. The model has been validated, and a good agreement was observed.
Load-deformation of piled embankments considering geosynthetic membrane effect and interface friction
Authors: Pham Tuan A.
Published: May 2019

The use of high-strength geosynthetics to enhance the load transfer mechanism onto columns is an established and increasingly popular technique in geosynthetic-reinforced and column-supported embankments. The main focus of this paper is to extend the existing models that describe the membrane action and soil arching with skin friction along the geosynthetic. This extension was undertaken to identify the parameters that affect the tension in the geosynthetic and assess the effect of geosynthetics on the load transfer. A general expression for the increase in load-bearing capacity due to the membrane action based on strict equilibrium conditions is also shown. The geosynthetic deformation is described assuming both circular and parabolic deformation shapes. These two deformation shapes do not result in a significantly different membrane effect. Therefore, the choice of deformation parameter is more important than the choice of deformation shape. The new method using both deformation models was combined with the Concentric Arches model of Van Eekelen and co-workers, and compared with the measurements and numerical results. A reasonable consistency is found. For the considered cases, the skin friction along the geosynthetic reduces the maximum geosynthetic deflection to 2.5 to 5.3%. This reduction becomes more important when the embankment is higher.

Authors: DURMAZ Hasanali
Published: May 2019

Amaç

Bu
çalışmada, yüzeyel femoral arter stenoz ve oklüzyonlarında endovasküler yolla
tedavi edilen hastalarda deneyimin, teknik başarının ve periprosedüral
komplikasyonlara yaklaşımın sunulması amaçlandı.

Gereç ve Yöntemler

Haziran
2012 ve Aralık 2018 tarihleri arasında hastanemiz girişimsel radyoloji
ünitesine yürüme ağrısı ve kritik ayak iskemisi nedeniyle yönlendirilen,
yüzeyel femoral arterde stenoz veya oklüzyon saptanan 40 hastanın (11 kadın, 29
erkek) kayıtları retrospektif olarak incelendi. Hastalar tedavi kararı
öncesinde klinik öykü ve bulgularının yanı sıra Doppler US, BT anjiyo veya
dijital subtraksiyon anjiyografi ile değerlendirildi. İşlemi kabul eden
hastalara endovasküler tedavi ile primer perkütan translüminal anjiyoplasti ve

LPS tarafından oluşturulan endotokseminin patofizyolojik mekanizmalarının anlaşılmasında ve tedavisinde pek çok strateji geliştirilmesine rağmen, hala yoğun bakım ünitelerinin büyük bir problemidir.Bu çalışmada, endotoksik şok üzerine Apilarnilin koruyucu bir etkisi olup olmadığının, testis dokusunda histopatolojik değerlendirme ve DNA yapısındaki değişimler ortaya konularak belirlenmesi amaçlanmıştır.Çalışma için 64 adet Sprague-Dawleycinsi yetişkin erkek sıçan rastgele seçilerek 8 eşit gruba ayrılmıştır.Testis dokusunda rutin hematoksilen eozin boyaması ile histopatolojik değerlendirme yapılmış, komet testi ile DNA yapısındaki değişiklikler, 6. saatin sonunda kontrol grubuyla karşılaştırılmıştır. Histolojik değerlendirme sonucunda artan dozlarda apilarnil uygulanan gruplardan alınan testislere ait kesitlerde kontrol grubu ile benzer şekilde histolojik yapı gösterdiği gözlenirken, LPS ve artan dozlarda apilarnil uygulanan gruplara ait testis dokusunda artan dozla birlikte lümendeki sperm miktarının arttığı görülmektedir. Buna ek olarak, LPS grubu ile karşılaştırıldığında bu gruplara ait seminifer tübüllerdeki hücreler arası bağlantı yerlerinde daha az ayrılmaların olduğu görülmektedir. DNA yapısındaki değişimler değerlendirildiğinde; LPS, uygulanan grupta kuyruk DNA yüzdesinde, kuyruk uzunluğunda ve kuyruk momentinde istatistiksel olarak artışa neden olmuştur. LPS+Apilarnil'in verilmesi DNA hasarında azalmaya neden olmuştur.Apilarnil’in artan dozları DNA yüzdesi ve kuyruk uzunluğunda istatistiksel olarak azalmaya neden olmuştur. Sonuç olarak, Apilarnil artan dozlarda uygulanmasının, LPS'nin neden olduğu testiküler hasarı azaltığını ve bu etkinin de apilarnilin antioksidan kapasitesinden kaynaklandığını düşünmekteyiz.

La presente investigación tuvo como objetivo determinar la relación entre la motivación del logro y la resolución de problemas con funciones lineales de los estudiantes de Fundamentos para el Cálculo del turno tarde de la Facultad de Negocios en la Universidad Peruana de Ciencias Aplicadas, 2017. Este estudio se desarrolló dentro de un enfoque cuantitativo, con un método hipotético deductivo y diseño no experimental. La muestra estuvo conformada por 76 estudiantes de Fundamentos para el Cálculo de la Facultad de Negocios de la universidad mencionada. Los resultados permitieron determinar que no existe relación directa y significativa entre la motivación del logro y la resolución de problemas con funciones lineales de los estudiantes encuestados. Esto demostró que la competencia de resolver problemas no depende de la motivación, sino más bien se requiere de conocimiento y habilidades que se manejen.
Hyponatremia and metabolic alkalosis in a foal with gastroesophageal relux: A case report
Authors: Die E. , Estepa J.C. , Lopez I. , Zafra R. , Rodriguez M.
Published: May 2019

A foal with a history of diarrhea and fever was presented to the Equine Clinic of the University of Cordoba for acute onset of abundant serous nasal discharge. On endoscopic examination the oesophagus was found to be atonic and ulcerated, the cardia was permanently open and the stomach showed extensive ulceration. In addition, the nasal discharge was identified to have a gastric origin (gastroesophageal reflux). The electrolyte and acid-base profiles showed marked hyponatremia (99 mEq/l) and metabolic alkalosis (pH = 7.46, Strong Ion Difference = 50 mEq/l). The foal was also uremic (plasma creatinine = 12.6 mg/dl). Although the foal experienced an improvement in its hydroelectrolytic status after treatment with 7.5% NaCl for 36 h, the owner requested eutha- nasia. The foal described here developed severe hyponatremia and hyposmolarity but, contrary to most reported cases, showed metabolic alkalosis instead of metabolic acidosis. Another interesting feature of this case is the lack of overt neurologic signs in the face of extreme hyposmolarity. The paucity of neurologic signs in this foal may have been influenced by slow instauration of hyponatremia, concurrent azotemia, or acid-base status.

THE SPECIFIC OF PSYCHOSOCIAL WELL-BEING OF INTERNALLY DISPLACED PERSONS
Authors: Holotenko А.
Published: May 2019

The article is devoted to the problem of psychosocial well-being of internally displaced persons. The situation of forced internal migration conceals a large number of destructive influences on the psychosocial well-being of the individual. The process of adaptation of forced migrants is accompanied by high levels of stress and requires a large amount of psychological and social resources. In this regard, the research of psychosocial well-being of internally displaced persons is relevant to the scientific substantiation of psychosocial practice of assistance IDP.

The purpose of the article is to reveal the peculiarities of the psychosocial well-being of internally displaced persons, which are based on the results of empirical research. The article presents the results of a theoretical and methodological analysis of the concept of psychosocial well-being of internally displaced persons. This concept is interpreted by the author as a multifactorial construct, which encompasses the individual psychological characteristics of internally displaced persons, their subjective attitude to the actual life situation, the nature of social interaction with others and economic factors of life activity. The results of empirical research aimed at identifying the characteristics of psychosocial wellbeing of internally displaced persons point to a reduced level of psychosocial well-being of internally displaced persons, reflected in the manifestations of the tendency to disadaptation. Characteristic features of internally displaced persons are the inability to establish close social contacts with others and emotional detachment and lowered sense of their value to society. The general emotional background of the IDP is at a reduced level and is characterized by tendencies towards negativism.
ANALYSIS OF THE SOCIO-ECONOMIC DEVELOPMENT IN LATGALE AND UTENA REGIONS
Authors: Vaitiekus Edmundas
Published: May 2019

It is widely acknowledged that border regions of the country are often economically "lagging" compared to more developed areas. The level of economic and social development is a key factor in the political, economic and social efficiency of any economic entity. In areas where development is slower, there is a decrease in economic efficiency in the private sector and deterioration in the effectiveness of political governance in the public sector. The research aim is to analyze and compare the development possibilities in Latgale and Utena regions. Main research methods are content analysis, statistical analysis of data. The planning and strategic documents were analyzed in order to study the situation in Latvia and Lithuania at national, regional and local level. Statistical analysis was performed using data from the Central Statistical Bureau of Latvia and the Lithuanian Department of Statistics. An assessment of the extent and trends of territorial inequality could be a useful tool for developing adequate regional development strategies which seek to reduce economic and social imbalances.
THE ROLE OF LITERARY WORKS IN THE FORMATION OF VALUE ORIENTATIONS IN ADOLESCENTS: PSYCHOLOGICAL ASPECT
Authors: Breus Yuliia , Kozlov Roman , Virchenko Tetiana
Published: May 2019

The article is devoted to the problem of developing values among adolescents, along with the significance of literature in this process. Adolescence with all its complexity and contradictions is a period of intensive development of the value system, which influences both character-building and personality in general. The authors of the study have identified fundamental characteristics of values and value perspectives of youth, and reasonably established specific factors in their formation while studying literary works. A teenager perceives life values only in personal, concrete embodiment. For this reason, literary works and their protagonists are rightly considered an effective way of passing on a set of values from generation to generation. The information theoretic unit of the article is complemented by the results of the empiric interdisciplinary research with basic concepts defined, sample characteristics and research methods given, and the outcomes of the experiment presented. Using M. Rokeach’s value list, the authors have defined the value system of modern adolescents, and analyzed the mechanisms of their formation through the curriculum pieces of Ukrainian literature.

Published: May 2019

In this work we describe the distribution of stable carbon isotopes in hydrocarbon gases from four wells located in the southern and central parts of the Western Siberia. The main goal was to understand the influence of the lithological composition and geological settings on isotopic composition of gases and their formation. Two genetically different groups of hydrocarbon gases were identified based on the author’s research, as well as analysis of archival and literature materials on the isotope composition of hydrocarbons. We estimated the close relationship between the main factors of the migration, degree of metamorphism of organic matter and the isotope composition of hydrocarbon gases produced by the Bazhenov formation.

The paper considers possibilities of relay systems for the conveyor speed control. Computational procedures have been developed for simulating the relay speed control of a conveyor with and without a loading hopper with discrete representation of the incoming freight flow. Estimates of the sampling time of the incoming freight flow are obtained. The requirements for conveyor speed regulator simulator are developed. Examples of simulation using MathCAD are given. The average value of the speed, the hopper capacity and the rate of speed switching are taken as the criteria for the efficiency of regulation. It is shown that the average speed decreases most distinctly with two- and three-stage regulation. A further increase in the number of regulation stages slightly reduces the average speed, but significantly increases the rate of speed switching. Installing the loading hopper allows significant reducing the nominal conveyor capacity and the average speed. The results of the work can be used in the design of conveyor drives with a relay speed control systems

Authors: Mosolov S.V. , Sidlerov D.A.
Published: May 2019

The paper considers the specifics of gasification, mixing and burnout processes for propellant components in a combustion chamber featuring coaxial bicentrifugal injectors and operating in the liquid/liquid mode employing oxygen and the T-1 and T-6 kerosene types. Numerical simulation revealed that when using the T6 fuel, the structure of recirculation zones appearing in the leading region of the combustion chamber may provide more efficient oxygen and kerosene mixing and burnout as compared to a chamber running on the T-1 fuel

Published: May 2019

The kinetics of dissolution of iron oxides FeO, α-Fe2O3 and Fe3O4 in orthophosphoric acid, including those containing additions of Fe (II) and Fe (III) ions (in the form of perchlorates), has been studied. The values of the stationary potential in the magnetite electrode system--solutions of orthophosphoric acid, including those containing additions of Fe (II) and Fe (III) ions are determined. The dissolution of Fe3O4 in orthophosphoric acid has been studied and described. Based on the experimental results, it was established that the stimulating and inhibitory effect of Fe (II) and Fe (III) ions is related to their effect on the value of the potential at the boundary of the iron oxide phases/electrolyte solution. The orders of reactions for ions Fe (II), Fe (III) and H3PO4 are determined
Quasielastic and Low-Frequency Raman Light Scattering in Lithium Niobate Crystals with Stoichiometric Defects
Authors: Anikiev A.A. , Umarov M.F. , Anikieva E.N.
Published: May 2019

The paper investigates quasielastic light scattering spectra at a temperature of 296 K in lithium niobate samples of various degrees of imperfection as measured by means of the acoustic quality factor. We performed a quantitative spectrum analysis in the 0--70 cm-1 frequency range for samples with different Q-factor values in a model accounting for the connection between a low-frequency optical mode of the A1(TO) symmetry type and the acoustic density of states observed in a spectrum as a result of violating the wavevector selection rule in a stoichiometrically defective crystal. The results of comparing these simulations to experimental data show that stoichiometrical defects significantly contribute to the quasielastic light scattering intensity in congruent lithium niobate crystals
Nickel-Dopant Atom Clusters and their Effect on the Recombination Properties of Silicon
Authors: Zaynabidinov S.Z. , Kurbanov A.O.
Published: May 2019

The investigation determined the types and nature of structural defects in n-type silicon featuring nickel-dopant atom clusters by using deep-level transient spectroscopy (DLTS) and measuring specific resistance, concentration and lifetime of charge carriers. The investigation employed the Solver-NEXT infrared and atomic-force microscopes. We observed that after high-temperature diffusion star-like defects appear in those Si samples that were cooled slowly. Rapid cooling of Si samples yields no decorating of dislocations, which is linked to formation of [Ni-O]-type point defects, [Ni-Si] silicides and Ni[Nis-Nii] atom pairs (unlike in the case of slowly cooled doped Si samples). The differences in shape and size of the defects forming in slowly and rapidly cooled Si samples may be explained as follows: in the case of slow cooling, as the system transitions into the equilibrium state, its free energy decreases, and nickel atoms gradually precipitating at the defects of the crystal lattice form inclusions characterised by the most energetically favourable state, that is, star-like defects. We detected an increase in charge carrier lifetime caused by formation of a trapping level connected to the [Ni-O] complex in silicon
Analysis of the possibility of suppressing spacecraft antenna torsional vibrations by means of dynamic absorber
Authors: Khrupa S.K. , Tushev O.N.
Published: May 2019

The paper deals with dynamics of truss antenna systems with a dynamic absorber in the region of low-frequency natural torsional vibrations. The use of a dynamic absorber is due to the weak dissipative properties of the antenna system. Owing to the internal resonance, energy is transferred from the elastically fixed antenna system to the dynamic absorber, whose vibrations are damped quite simply. A theoretical study of the dynamic characteristics of the absorber was carried out on a simple linear model of a two-degree-of-freedom vibrating system. The equations of motion are integrated numerically. Findings of research show that the mass of the dynamic absorber is about 5% of the mass of the reflector, the absorber should be as far as possible relative to the axis of rotation of the system, and it can be used instead of balancing weights. The ranges of design parameters of the dynamic absorber and the levels of loads at which it operates efficiently are determined
Reliability calculations for a system with heterogeneous subsystem redundancy
Authors: Pavlov I.V. , Orlova A.O.
Published: May 2019

The purpose of the paper was to study the problem of confidence estimation of basic reliability indicators, such as the system failure-free operation probability for a given time and guaranteed uptime, with a given guarantee level, for a system model with arbitrary redundancy modes, loaded or unloaded, in various subsystems. When studying the problem, we relied on the elements test results. Problems like that are often found in engineering practice when designing and experimentally developing modern complex engineering systems and their various components. The paper gives the construction of lower confidence limits for the indicated main indicators of the system reliability based on the available statistical information on the test results of its elements, and also presents approximate asymptotic (for the case of high reliability) expressions obtained for the lower confidence limit of the system reliability function
Are Women better Leaders than Men? Gender Differences in Management Styles
Authors: Mamadou Sylla
Published: May 2019

Management is the set of management or administrative techniques that can direct, guide, coordinate and control resources (human and material), performance within an organization to achieve one or more objective (s). Better, others think that it is the action, the art or the way of leading an organization, to direct it, to plan its development and to control it. That could lead to the concern that humankind and his half are manipulating differently? To answer this problem, we will first of all study the qualities of a good manager, considered as the repository. Then, we will analyze the different management styles used by men and women as well as their impact on group cohesion.

Published: May 2019

Change is the only constant phenomenon in this world, and organizations can bring it through innovation. This innovation ultimately leads to an organization’s competitive edge and sustainability. Every new idea primarily originates in the minds of individuals, and when it’s implemented successfully, it contributes to overall organizational innovation. Nurturing employees’ innovative work behavior (EIWB) is prudent for every organization looking to enhance its innovative outcomes. This research, at first, aimed to examine the influence of servant leadership (SL) at three distinctive levels of employees’ innovative work behavior (EIWB); namely, idea generation, idea promotion, and idea realization. Then, we investigated the influence of SL on overall EIWB. Finally, employees’ Psychological Empowerment (PE) is assessed as a mediator through which SL exerts its influence on EIWB. Servant leadership in conjunction with Social Exchange theories were used to develop the conceptual model of this research. Cross-sectional data were collected from 283 entry-level officers working in different Power Sector Companies of Pakistan. Partial least squares structural equation modeling (PLS-SEM) was employed through Smart-PLS 3.2.8 software to analyze the hypothesized relationships. The findings of this research show that SL positively influences each stage of EIWB as well as EIWB at an integrated level. Employees’ Psychological Empowerment (PE) partially mediates the positive influence of SL on EIWB. This research is one of the pioneers to examine the influence of SL at different levels of EIWB. Further, investigating employees’ PE as mediating between the relationship of SL and EIWB is also a unique contribution of this research. Besides offering the theoretical and managerial implications, detailed discussion on the results is carried out. Lastly, the limitations of this study and potential avenues for future research are highlighted.
