Podpułkownik dyplomowany Zdzisław Chrząstowski (1891–1939). Zarys biografii
Authors: Jarno Witold
Published: January 2023

Artykuł opisuje życie i karierę wojskową ppłk. Zdzisława Chrząstowskiego (1891–1939). Urodził się w Guberni Kowieńskiej w polskiej rodzinie szlacheckiej. Po ukończeniu szkoły średniej rozpoczął służbę wojskową w armii rosyjskiej, a następnie w polskich formacjach zbrojnych tworzonych w Rosji. Brał udział w słynnej bitwie pod Krechowcami w 1917 r. Po rozbrojeniu 1 Korpusu Polskiego pojechał na północ Rosji, gdzie formowały się nowe polskie oddziały. Na początku 1919 r. drogą morską przybył do Francji i został żołnierzem Błękitnej Armii gen. Józefa Hallera. W składzie 1 Pułku Szwoleżerów wiosną 1919 r. powrócił do Polski i brał udział w wojnie polsko-rosyjskiej. Za wykazaną odwagę otrzymał Order Virtuti Militari V klasy. W 1923 r. uzyskał tytuł oficera Sztabu Generalnego. W kolejnych latach pracował m.in. w Dowództwie Okręgu Korpusu nr IV w Łodzi i Generalnym Inspektoracie Sił Zbrojnych. Zajmował także stanowisko zastępcy dowódcy 1 Pułku Ułanów Krechowieckich (1928–1931) oraz dowódcy 4 Pułku Ułanów Zaniemeńskich (1936–1938). W II Rzeczypospolitej był cenionym teoretykiem działań taktycznych kawalerii, autorem wielu artykułów o tej tematyce. W 1939 r. objął stanowisko oficera sztabu Armii „Łódź” dowodzonej przez gen. Juliusza Rómmla. Sztab armii ulokowany został w dawnym pałacu Juliusza Heinzla w Łodzi, zbombardowanym 6 września przez niemieckie samoloty. Jedną z ofiar nalotu był ppłk Chrząstowski, który zginął od odłamków jednej z bomb.
Szkoły elementarne na Lubelszczyźnie w okresie okupacji austriackiej (1915–1917)
Authors: Partyka Wiesław
Published: January 2023

Głównym celem artykułu jest opisanie stanu polskiego szkolnictwa elementarnego na Lubelszczyźnie w czasie I wojny światowej, przed odzyskaniem przez Polskę niepodległości. Szkolnictwo elementarne opisywanego okresu opierało się przede wszystkim na małych szkołach jednoklasowych z jednym nauczycielem, jedynie w większych ośrodkach miejskich funkcjonowały szkoły wieloklasowe. Dzięki wielkiemu zaangażowaniu wielu społeczników (np. właścicieli ziemskich, duchowieństwa), ale i zwykłych obywateli, początek XX w. charakteryzował się nienotowanym wcześniej wzrostem liczby szkół, które umożliwiały dostęp do edukacji tysiącom dzieci i młodzieży. Mimo zniszczeń wojennych, braku infrastruktury szkolnej, niedoboru kadry dydaktycznej, mobilizacja społeczeństwa oraz przychylna w tej materii postawa władz austriackich, doprowadziła w latach 1915–1917 do wzrostu liczby szkół elementarnych z 426 do 1345. Dzięki temu liczba uczniów objętych edukacją wzrosła z około 30 tys. w 1915 r. do ponad 100 tys. w 1917 r. Ważnym osiągnięciem było również przekazanie przez władze austriackie jurysdykcji nad szkolnictwem administracji polskiej już na rok przed odzyskaniem niepodległości. Mimo wzmożonych działań, w ciągu kilku lat nie udało się nadrobić zaległości wynikających z polityki edukacyjnej władz rosyjskich realizowanej przez cały wiek XIX, jednak był to niezwykle istotny asumpt do odrodzenia i organizacji polskiego szkolnictwa w kolejnych latach. Artykuł bazuje na źródłach archiwalnych i opracowaniach z początku XX w., ukazując stan szkolnictwa nie tylko w ośrodkach miejskich, ale również na wsiach. Dzięki zachowanym sprawozdaniom, daje możliwość poznania szczegółowej sieci szkół, co może być przyczynkiem do podejmowania kolejnych badań w tej materii.

Problems with the history of Southern Slavs in the Slavic studies of Ukrainian scientists of Eastern Galicia during the 19th century
Authors: Fedoriv Iryna
Published: January 2023

The article analyzes the scientific heritage of Ukrainian scientists of Eastern Galicia in the 19th century on current issues with the history of South Slavic peoples. Its content, topics and methodology in the context of the development of national Slavonic studies are described. Special studies on the history of Bulgaria, Serbia, Croatia and Montenegro are analyzed. The most comprehensive of these studies are the scientific investigations of Denys Zubrytsky: Statement about Montenegro People; and Jakyw Holovatsky: Types of Slavic Peoples. Bulgarians, On the Transdanubian Slavs living on the Balkan Peninsula, Greater Croatia or Galician-Carpathian Rus. The content and problems of these studies give ground to claims that Galician scholars have a weak, sporadic knowledge of these peoples compared to the history of the Western Slavs. In spite of this, the questions raised by the scholars on: the peculiarities of the introduction of Christianity by Cyril and Methodius in Bulgaria; cultural, national, religious policy of the Ottoman Empire towards the Southern Slavs; the liberation movement of Bulgarians, Serbs, Montenegrins in the 19th century, etc.; testify to the scientific interest of scholars of Eastern Galicia in the Southern Slavs. At the same time, the interpretation of their history was of a civilizational nature and reflected the general trends in the development of Ukrainian historical Slavic studies in the 19th century.

Authors: Chuchalin Oleksandr
Published: January 2023

The article deals with charitable activities of Kyiv eparchy monasteries and convents during the second half of the 19th century and the early 20th century. It shows that charitable activities of the Orthodox church reached its peak in the post-reform period. The charitable activities within the specified time frame lay in the provision of schools, hospitals, orphanages, almshouses, and hotels for the poor and pilgrims. Kyiv eparchy monasteries and convents a) distributed alms, organized free lunches, provided material and medical assistance, b) handled education issues by establishing parish schools, c) supported almshouses by aiding sick people, lonely elderly people, people with special needs, and the mentally ill. At the beginning of World War I, Kyiv eparchy monasteries and convents became actively involved in the provision of assistance to the population, as well as the establishment and maintenance of shelters for children (orphans) of fallen soldiers. Such children were provided with proper care and timely medical assistance. Charitable institutions at the premises of Kyiv eparchy monasteries and convents operated at the expense of funds received from their economic activities, as well as donations from private individuals. Kyiv eparchy monasteries and convents  comprised the greatest number of hospitals and almshouses of all those operating in the territory of the then Kyiv Governorate.

Authors: Raha Shrinwantu , Gayen Shasanka Kumar
Published: January 2023

Although the variability and prediction of rainfall is an essential issue of the Santhal Pargana Division of the Jharkhand State but the issue is still far from its’ conclusive statement till date. Therefore, this study aimed to simulate the monthly rainfall from 1901 to 2020 using an eight-step procedure. After downloading the monthly rainfall for the Santhal Pargana Division from 1901 to 2020, the TBATS and Naive models were used to simulate the rainfall. The accuracy assessment of each model was done by using the MASE, MAE, RMSE, ME, and R. For the Naïve model, the Godda station was noticed with a comparatively high combined error. The lowest combined error was found for the Pakur station in case of Naïve models. Similar result was also obtained for the TBATS model. The TBATS was found with comparatively higher accuracy, as the combined error was less for the TBATS. The spatial assessment for the standardized rainfall varied from 84.419 mm. to 149.225 mm. For the Naïve predicted model, the rainfall was marked in between 8.133 mm. to 67.059 mm. For the TBATS fitted model, the rainfall fluctuated from the 37.127 mm. to 62.993 mm. Dumka station was noticed with comparatively low rainfall (i.e.,37.127 mm.). Deoghar and Jamtara stations were marked with a moderate rainfall. Remaining stations were marked with higher amount of rainfall for the TBATS fitted model. The Wilcoxon test proved that each model was significant at 95% confidence interval. The result produced in this research is fruitful enough to be utilized for agricultural planning in the Santhal Pargana Division of the Jharkhand state, India.

Engenharia Biomédica (EB) é área recente no Brasil, campo de possibilidades para profissionais das Ciências Exatas e Saúde. Cursos de graduação em EB iniciaram no país nos anos 2000 e muitos docentes ainda são de diferentes áreas do conhecimento.O objetivo foi conhecer perfil e processo de escolha profissional docente na EB. Do estudo, qualitativo e com abordagem biográfico-narrativa, participaram 11 docentes de um curso de EB, três mulheres e oito homens atuantes em uma universidade do vale do Paraíba paulista. Dados sociodemográficos e              sobre a formação foram obtidos na plataforma Lattes e confirmados durante as entrevistas do tipo  reflexivas (SZYMANSKI, 2011). Foram   realizadas em dois momentos, sendo no primeiro um relato livre e no segundo a devolutiva do conteúdo produzido. Os relatos, gravados, transcritos e organizados em biogramas (BOLIVAR, 2002), permitiram a identificação de momentos que influenciaram na escolha profissional. Os docentes entrevistados tinham formação acadêmica diversificada, eram doutores, majoritariamente do sexo masculino, média etária de 43 anos e tempo de carreira docente 9,3 anos.  Diversos caminhos os levaram os docentes à EB, como a escolha da carreira e possibilidades de atuação profissional. Acontecimentos marcantes  promoveram aproximação com a área. Apesar de não ter sido a primeira escolha de carreira, EB se mostrou como opção de formação e oportunidade de atuação profissional. Os resultados indicaram a importância de ampliar  reflexão sobre escolha profissional e formação em EB, de forma a promover, estimular e compartilhar alternativas que contribuam para promoção  dos saberes e favoreçam a formação de novos profissionais.
Eu só quero criar peixes! A construção de significados para conceitos químicos em um curso de aquacultura
Authors: Quadros Ana Luiza de , Ferreira Dalva Ester da Costa , Corrêa Roberta Guimarães
Published: January 2023

A partir de perspectivas construtivistas, a aprendizagem implica na busca pelo significado das “coisas”. Aprender Química na sala de aula, portanto, remete à construção de significados para os conceitos que ali circulam e, no Ensino Superior, é indicado que esses conceitos sejam associados ao campo de trabalho futuro do aprendiz. Com o objetivo de construir significados na disciplina de Química Geral ofertada aos estudantes de um curso de Aquacultura, desenvolvemos as atividades que culminaram neste trabalho. Para isso, usamos estratégias oriundas da aprendizagem baseada em problemas em uma turma de estudantes desse curso e analisamos o envolvimento deles com as atividades. Observamos uma valorização do conteúdo desenvolvido e uma participação ativa dos estudantes em todas as etapas. A maior valorização da disciplina observada nessa turma pode trazer implicações para os professores de Química Geral, além de nos desafiar a planejar novas experiências.

Authors: Tischer Wellington , Turnes Valério Alecio
Published: January 2023

Introdução/Objetivo: O objetivo do presente artigo é analisar a distribuição dos Programas de Pós-graduação (PPGs) stricto sensu na Região Sul no século XXI. Os PPGs representam parte significativa da pesquisa aplicada e básica dentro das Instituições de Ensino Superior (IES) realizada no Brasil e que vem se interiorizando a partir de políticas públicas de educação superior. Metodologia: Foram utilizados dados secundários a partir da base disponível no Sistema de Informações Georreferenciadas da Capes (Geocapes) para os anos de 1998 e 2018. A expansão de PPGs expõe diferenças entre os três estados em termos de capital e interior, público e privado, áreas do conhecimento e conceitos dos cursos. As universidades particulares contribuem com a expansão de PPGs em vazios deixados pela oferta pública no interior de Santa Catarina e Rio Grande do Sul e na capital do Estado do Paraná. Resultados: A reestruturação recente de institutos e universidades federais tem produzido efeitos na pós-graduação como uma dispersão de PPGs no interior e a concentração de excelência em pesquisa em IES consolidadas. PPGs nas áreas multidisciplinares e mestrados profissionais constituem as áreas do conhecimento e graus acadêmicos que mais cresceram no período sendo ainda restrita sua condição de excelência. Conclusão: Como considerações finais é apresentada a tendência de crescimento de PPGs em ciências da vida, exatas e tecnológicas em novos campi, novas universidades e institutos federais criados a partir de 2000 em municípios do interior.

Authors: Dias Janete Francisca , Branco Juliana  Cordeiro Soares
Published: January 2023

Este artigo é um recorte de uma pesquisa de mestrado intitulada: Processos Formativos de docentes atuantes em cursos de bacharelado e as implicações em sua prática pedagógica. A pesquisa busca investigar os processos formativos vivenciados por docentes de cursos de bacharelado na trajetória profissional e as implicações em sua prática pedagógica. Espera-se com a pesquisa ampliar o conhecimento sobre o papel dos professores universitários e a importância de se fomentar, no âmbito das Instituições de Educação Superior, estratégias voltadas à formação destes profissionais. Neste estudo, de natureza quanti-qualitativa, investigaremos as produções acadêmicas publicadas no decênio 2007-2017 sobre a temática: formação pedagógica de professores universitários, tendo como objetivo conhecer as contribuições dessas pesquisas na construção do conhecimento produzido na área. Foram utilizados como fonte de informação os trabalhos completos publicados nos Anais da Reunião Anual da Associação Nacional de Pós-graduação e Pesquisa em Educação – ANPED; No banco de teses e dissertações da Biblioteca da Universidade Federal de Minas Gerais – UFMG e em sites que divulgam produções relacionadas à área de educação. Com base nas informações dos quadros 1 a 10, constatamos que as discussões acerca desta temática ainda são incipientes. Os resultados revelaram que a formação pedagógica de professores ainda é pouco valorizada no ambiente universitário, sem a legitimação necessária por parte das instituições de educação superior.
Metodologias ativas nas concepções de docentes do ensino superior
Authors: Ferreira Giselle Martins dos Santos , Ozório Gabriela Gonçalves , Moreira Laélia Carmelita Portela
Published: January 2023

Este artigo explora dados produzidos em uma pesquisa cujo objetivo consistiu em caracterizar confluências e disjunções entre as concepções e práticas pedagógicas de docentes do Ensino Superior (ES) e ideias associadas às Metodologias Ativas (MA). O texto discute os achados de uma análise de conteúdo categorial de cinco entrevistas conduzidas entre outubro de 2019 e março de 2020 no âmbito de uma pesquisa de métodos mistos realizada em uma instituição de ES privada. Tomou-se, como fundamentação teórica, pesquisas focalizadas em usos de MA no ES, textos acerca da docência e da inovação no ES, bem como literatura da História da Educação e da Didática. A discussão está organizada em torno das seguintes temáticas: trajetória na profissão docente; planejamento e dinâmica na sala de aula; concepções sobre inovação; e concepções de MA. Sugere-se que, apesar de os professores declararem ter pouca familiaridade com as MA, que é, de fato, uma expressão relativamente recente, muitas das estratégias de ensino relatadas por eles são consistentes com as práticas e fundamentos teóricos dessas metodologias conforme explicitado na literatura pertinente. Assim, por um lado, reitera-se que sempre há espaço para a inovação pedagógica no sentido de adaptação a novos contextos e demandas. Por outro, sugere-se que ideias em torno de proporcionar estímulo ao protagonismo dos estudantes têm uma história mais longa e já podem ser parte integrante, ainda que tácita, do repertório de professores do ES de forma bem mais ampla do que os discursos de defesa do caráter inovador dessas metodologias parecem sugerir.
A docência universitária

Published: January 2023

A formação docente universitária configura-se como um desafio histórico constituído desde a origem da própria universidade devido a sua natureza principal ser relacionada à pesquisa. A formação em Ciência da Computação para o Ensino Superior, em específico, representa-se com uma temática desafiadora na realidade universitária e em estudos acadêmico-científicos. Nesse sentido, este artigo apresenta um estudo realizado no Departamento de Ciência da Computação na Universidade Federal da Bahia (UFBA), em Salvador- Brasil. Como metodologia, utilizou-se a pesquisa qualitativa e pesquisa-ação com procedimentos direcionados à revisão de literatura, observação em sala de aula e formação dos docentes do departamento referido. Este estudo busca contribuir para a discussão sobre a formação docente universitária na Ciência da Computação, de modo a compreender as necessidades da área e a relação sistêmica que deveria contribuir para o Ensino da Computação e a disseminação do pensamento computacional. Como resultado, observa-se que as formações oferecidas na Pós-Graduação aos professores universitários poderiam ser instituídas de maneira interdisciplinar com encaminhamentos didático-pedagógicos e específicos, enfatizando a constituição dos saberes necessários ao exercício da docência no Ensino Superior. Ainda nota-se a ênfase dada à pesquisa em detrimento à formação do docente universitário em nível de Mestrado e Doutorado, com ausência de uma atuação sistêmica entre as várias modalidades de ensino, bem como reflexões sobre a prática docente no Ensino Superior.
Las visiones del Banco Mundial sobre el modelo de desarrollo asiático
Authors: Berasaluce Iza Julen
Published: January 2023

En el artículo se analizan los elementos discursivos de los principales informes regionales del Banco Mundial sobre Asia del Este, a fin de identificar la perspectiva predominante en esta influyente institución. Se reconoce, aunque con algunas excepciones —como en 2007—, una visión fundamentalmente neoclásica que confronta, en ocasiones explícitamente, las tesis del banco con las de acercamientos desarrollistas. Desde una amplia visión, la institución no ha sido exitosa en la identificación de cualidades diferenciales de lo que conformaría un modelo asiático de desarrollo. La caracterización de las interpretaciones desarrollistas alternativas puede corregir los límites de la perspectiva del banco.

Published: January 2023

Introduction: COVID-9 is a global pandemic and causes changes in behavior and life. The implementation of health protocols is the most important aspect to prevent the transmission of COVID19, especially in the Islamic boarding schools (Pondok Pesantren) community. The aim of this study is to identify the practice of a clean and healthy lifestyle as well as the application of health protocols in the Pondok Pesantren to control the spread of COVID-19.
Methods: The preliminary survey was conducted as a part of training for the healthy student cadre and the establishment of COVID-19 shelters in Pondok Pesantren in The Special Region of Yogyakarta, Indonesia. Fourteen questions including the name of Pondok Pesantren and multiple-choice questions related to clean and healthy living behaviors comparison before and during the pandemic, health protocol implementation during the pandemic, and provision of COVID-19 prevention and control program.
Results: Total sample consisted of 84 students from 18 Pondok Pesantren in The Special Region of Yogyakarta. Among the factors affecting the student’s compliance with health protocol implementation in Pondok Pesantren were the disparity of individual’s understanding and obedience to rules and regulations regarding health protocol implementation (71,8%), inadequate facilities (12,8%), and other factors including that there was no strict supervision and punishment for violation upon regulations.
Conclusion: Pondok pesantren is an institution that needs more attention amid the pandemic of COVID-19. Dense population, minimum infrastructure, and relatively poor access to healthcare facilities have made them a vulnerable community.
THERMOMETRIC MODEL OF DIODE TEMPERATURE SENSOR
Authors: Yaganov Petro , Pavlov L.M.
Published: January 2023

Background. Microelectronic technologies make it possible to create structures with high sensitivity to external influences. In semiconductor microelectronics, these are structures of the type of potential barrier at the p – n Junction. Silicon diode sensors have high temperature sensitivity in a wide temperature range. Both physical and formal mathematical models of the thermometric characteristic of the diode sensor have been developed. The temperature measurement error of some of these methods was not acceptable for the control of many processes. It is relevant to conduct studies of the temperature properties of the p – n Junction in a non-equilibrium state to formalize the new thermometric characteristic of the diode sensor. Objective. The purpose of the work is a model of thermometric characteristics of silicon diode sensors based on the results of measurements of volt-ampere characteristics in the temperature range. Methods. Analysis of methods of calibration of thermometric characteristic of diode sensors by volt-ampere characteristics was carried out, factors affecting temperature measurement accuracy were revealed, regression analysis method for formation of polynomial model of thermometric characteristic was substantiated. Results. As a result of studies of the volt-ampere characteristics of silicon diodes in the temperature range (248... 393) K, it was found that the error in measuring temperature by diode sensors is associated with the dependence of the non-ideality factor of the p – n Junction on temperature. The accuracy of the thermometric characteristic is estimated, where this functional dependence is represented as an approximation polynomial. Conclusions. An alternative model of thermometric characterization of diode temperature sensors by the second degree regression equation is presented. The arguments of the function are the current and voltage of the diode in the direct displacement mode. Current stability in the p – n Junction circuit is not assumed. The temperature determination accuracy in the temperature range (248... 393) K is within ± (0.2... 0,256) K
DESIGNS OF HEAT EXCHANGER DEVICES ON TWO-PHASE HEAT TRANSFER ELEMENTS FOR AIR HEAT DISPOSAL IN VENTILATION SYSTEMS: OVERVIEW
Authors: Alekseik Yevhenii , Alekseik Olha
Published: January 2023

Background. Heat exchangers-utilizers for recovery of ventilation air heat are widely used for increasing of buildings energy efficiency. Two-phase elements, such as: thermosyphons, heat pipes and pulsating heat pipes are applied to these heat exchangers for increasing of efficiency of heat transfer between hot and cold air. But such heat exchangers should have high temperature efficiency, enthalpy efficiency and energy efficiency at low aerodynamic drag. Moreover, working conditions of ventilation systems, such as: relatively low working temperatures and low temperature difference between hot and cold air, make it difficult to choose heat carriers for two-phase elements. Thus, it is necessary to solve a number of complex problems for designing of effective heat exchangers-utilizers based on two-phase elements.

Objective. To find out unresolved and understudied issues of designing of heat exchangers-utilizers based on two-phase elements for ventilation systems.

Methods. Analysis of described in literature designs, their characteristics and results of investigations.

Results. General features of two-phase elements based heat exchangers-utilizers designs and a number of issues which need further investigation were detected as a result of literature sources analysis.

Conclusions. Heat exchangers based on two-phase heat transfer elements have wide perspective of applying and provide full heat efficiency up to 85%. But there is a number of unsolved issues connected with: optimization of two-phase elements and heat exchangers design, ribbing optimization, investigation of heat transfer intensity and heat transfer coefficients, investigation of aerodynamic drag, condensate rejecting.

Authors: Kondratiuk Vadym
Published: January 2023

Problems. An urgent issue of ensuring the safety of nuclear power plants is the adaptation of the results of experimental qualification of the fittings of passive safety systems in a single-phase environment to emergency conditions of two-phase flows. For most of the equipment of systems important for the safety of nuclear power plants, there is no principled possibility of qualification through direct tests in emergency conditions. The experience of operating nuclear power plants, as well as the results of simulations after design accidents, determined the possible inconsistency of the operating conditions of the fittings in emergency situations and in the modes of operational tests with a single-phase steam-gas environment.Thus, it is necessary to adapt the results of the experimental qualification of the fittings of the emergency steam and gas removal systems in a single-phase environment to the emergency conditions of two-phase flows. The aim of the study. The purpose of this article is sufficient justification of the adaptation of test results on a single-phase environment to the conditions of emergency processes with a two-phase environment. Methodology of implementation. To achieve the goals of the study, deterministic modeling of the conditions and criteria of operation/testing of valves of emergency steam and gas removal systems was used. Research results. T An analysis of the validity of the results of the experimental qualification was performed for the dynamic pressure pressure on the closing device in the test mode (single-phase flow mode) and the dynamic pressure pressure on the closing device in the emergency mode (two-phase flow mode). The adaptation of the results of the experimental qualification for closing the valves of the emergency steam and gas removal systems in a single-phase environment to the emergency conditions of two-phase flows was carried out under the conditions of subsonic and supersonic flow regimes. Conclusions. The conditions for adapting the results of the experimental qualification for closing the valves of the emergency vapor gas removal systems to the emergency conditions of subsonic and transonic flows of two-phase flow in the flow part of the valves have been determined. The dynamic pressure on the closing device of the valve in single-phase flows of operational tests and the dynamic pressure in two-phase flows of emergency modes are considered qualification criteria.

A pair of Little Eagles Hieraaetus morphnoides in the Australian Capital Territory was recorded (on closed-circuit camera) feeding and mating on a nest and had added a layer of green pine sprigs in preparation for egg-laying. Many beetles, likely a species of Dermestidae, were recorded in the nest during the time that the birds were there. The Eagles abandoned the nest and moved to another 1.7 km away, where they laid a clutch. It is possible that the beetle infestation was the cause of abandonment.

A Review on Antimony-based Perovskite Solar Cells
Authors: Thomas Ankit Stephen
Published: January 2023

Abstract: Over the past decade, lead halide perovskite light absorbers have been the conventionally used perovskite light absorbers. However, there is an urgent call for alternative perovskite materials with toxicity levels and poor stability to UV radiations. Antimony-based perovskites have proven to be a material with unique optoelectronic properties, conventional fabrication processes, low-toxicity levels and high stability values. In this review, we look into the structure of antimony perovskites, the various research achievements over recent years, and the challenges and opportunities ahead for this budding technology. The review also highlights the various computational, theoretical and experimental studies done by researchers to highlight the peculiar Lead-free perovskite materials and their distinctive features. Although the efficiency levels of these devices are not very high, the improvements they have made with remarkable stability characteristics make them a viable candidate for commercial perovskite photovoltaics

The article presents the results of determination of the loading of a removable module for transportation of long freight in a combined train by the train ferry. The article describes the results of the mathematical modelling of the dynamic loading on a removable module placed on the flat car during rolling motion of the train ferry. It suggested that the flat car was rigidly fastened and displaced together with the deck. The displacements of the removable module relative to the flat car frame and the freight relative to the removable module were neglected. The mathematical model was solved with the method of variation of constants and confirmed by means of calculation in Mathcad. It was found that the maximum value of acceleration to the flat car with the removable module was about 2.35 m/s2 (0.24g). The value of acceleration obtained was included in the strength calculation for the removable module. The calculation was based on the finite element method and realized in SolidWorks Simulation with the Mises criterion. The finite element model was formed with spatial isoparametric tetrahedrons. The results of the calculation demonstrated that the maximum equivalent stresses were in the contact area between the vertical posts and the fittings; they amounted to 284.7 MPa. The stresses obtained were lower than the allowable values by 17.5%. The yield strength of the structural material was taken as the allowable stress. The equilibrium stability factor for the removable module was also determined. The strength of the removable module on the flat car without proper displacements and with the long freight inside was provided at the roll angles of the train ferry up to 25°. The results of the research will be of value for those who are dealing with development of transport facilities with better operational efficiency for combined transportation.Key words: removable module, dynamic loading, strength, equilibrium stability, train ferry transportation.

Higher operational efficiency of container transportation can be achieved by putting into operation hopper containers. The special feature of a container is its inclined end and sidewalls, which makes it possible to self-discharge bulk freight through the discharging hatches forming the floor. The vertical loading of a hopper container placed on the long-base flat car was determined with the mathematical modelling. The mathematical model described the translational movement of a flat car in the vertical plane, i.e. bouncing oscillations. The flat car for the calculation consisted of three bodies: bearing structure loaded with four containers and two 18-100 bogies. The containers were considered as attached masses that completely repeated the movement pattern of the bearing structure of the flat car in the vertical plane. The mathematical model also included the elastic characteristics of the track. The calculation was made for the containers placed on a long-base 13-7024 flat car. The mathematical model was solved with the Runge-Kutta method in MathCad. The initial conditions were equal to zero. It was found that the maximum acceleration in the mass center of the bearing structure of a flat car loaded with hopper containers was 1.28 m/s2, which did not exceed the allowable values. The vertical dynamic coefficient was 0.13. The motion of the flat car was estimated as excellent.The results of the research will be of value for those who are dealing with development of advanced container structures with better operational efficiency for container transportation.Key words: transport mechanics, hopper container, dynamic loading, dynamic characteristics, container transportation.

A well-executed training program using the right training method will result in an athlete's performance if the athlete gets sufficient recovery to recover from post-exercise fatigue. To find out the athlete's performance by knowing the oxygen volume capacity by using the balke test but the leg length of each athlete is suspected of contributing in carrying out the test so researchers want to examine the Effect of Training and Recovery Methods on VO2max of UNSIKA Rowing Club Athletes by Controlling the Effect of Leg Length. quasi-experimental method with a 2 x 2 factorial design. The research variables consisted of: (1) the dependent variable, namely VO2max Athlete Rowing Club UNSIKA (2) independent variables, namely the treatment variable (A1: Cross country method, and A2: Fatlek) and attribute variables ( B1: Passive Recovery and B2: Active Recovery) and (3) the covariate variable, in this study was Leg Length. So that the total number of research samples is 80 people. The Balke test is the test instrument used in collecting Vo2max data. as well as a tape measure to measure leg length. Hypothesis testing was carried out using two-way covariate analysis (ANKOVA) with a 2x2 factorial design. The results of the first hypothesis testing showed that the Vo2max results of the UNSIKA rowing club athletes between the athlete group using the cross country method were higher than the athlete group using the fatlek method after controlling for leg length. Thus the cross-country training method used in this study can improve the Vo2max results of UNSIKA rowing club athletes which are better than the fatlek method.

We wish to share with the readers of this scientific journal our experiences and observations regarding educational gains achieved by the consultant faculty and trainee postgraduate residents via active participation in multidisciplinary team (MDT) Tumor Boards. The rapid modernization of teaching methodologies is being observed in both postgraduate residents and faculty professional education learning processes. Contemporary literature is increasingly depicting academic work which is being directed towards the exploration of both educational and social determinants of health care [1]. Several socio-economic factors have been discussed across the globe which have an impact on the health care systems [2]. Researchers argued over the fact that the leading factor for a positive outcome is socioeconomic wellbeing especially for patients with diseases, like cancer, diabetes mellitus, etc. If we critically evaluate the curriculums designed on the principles of traditional problem-based learning and case-based learning, they are very well-established students centre approaches, but on their merit, they failed to provide a holistic picture of the patient care [3].

Introduction: Ankylosing Spondylitis (AS) is a chronic inflammatory rheumatic disease that mainly characterized by sacroiliac joint and spine involvement. Although there is no clear evidence that any of these agent prevent the radiologic progression, anti-TNF drugs provide significant improvements in the disease activity score, functional index and quality of life. In AS patients, knowledge of the factors that determine the need for anti-TNF treatment will be associated with fewer complication sand better treatment. The purpose of this study is to investigate the possible factors which willmark the transition to the anti-TNF therapy in AS patients. Materials and Methods: This study was conducted in the Rheumatology division of the Internal medicine department of the Ondokuz Mayis University of Medicine hospital between January 2012- June 2015. The study protocol was approved by the Ethics Committee of Ondokuz Mayis University. A total of 165 patients, who were diagnosed as AS according to the ASAS classification criteria, were enrolled in this study. There were 85 women (51.5%) and 80 men (48.5%), aged between 15-69. Patients were divided into two groups according to their use of anti-TNF drug. Results: A total of 165 Ax-SpA patients (85 women and 80 men) were included in the study. The mean age was 37.82±11.24 years. The mean duration of the disease was 4.59±5.35 years. male gender, uveitis, delay in diagnosis, elevations in sedimentation CRP levels, increase in disease activity and functional indexes such as BASDAI and BASFI scores shows the more frequent need for anti-TNF drug use. Conclusion: In our study, patients who needed anti-TNF treatment had a longer time between symptom onset and diagnosis than patients who did not hear. The delay in diagnosing these patients leads to a delay in treatment so that the focus of inflammation increases and these patients need more anti-TNF as this window of opportunity escapes.
