Authors: AKDAĞ Saffet , İSKENDEROĞLU Ömer
Published: June 2021

Uncertainties and risks are two leading factors affecting investors’ decisions. In the presence of uncertainty, investors may postpone consumption and investment decisions due to a wait-and-see policy, whereas consumption and investment decisions may be abandoned in risky situations. Due to its high demand elasticity, in particular, renders tourism as one of the sectors most affected by the increase in uncertainty and risks. In this context, it is aimed to determine whether or not any relationship between global Economic Policy Uncertainty index (EPU), global Geopolitical Risk Index (GPR) and global Volatility Index (VIX) and global tourism index STOXX Global 1800 T&L exists. The probable relationship between the variables is tested using monthly data over the period from August 2006 to December 2018 via Johansen cointegration test and DOLS and FMOLS cointegration coefficient estimators. As a result of the study, it is found that there is a long-term relationship between the related indices and the global tourism index and that the VIX and the EPU indexes have an adverse impact on the tourism index.

Published: June 2021

High-tech industry employees are among the most talented groups of people in the workforce, and are therefore difficult to recruit and retain.  We analyze employee reviews submitted by employees from five technology companies.  Following the Cross-Industry Standard Process for Data Mining (CRISP-DM) and the data science life cycle process, we use machine learning techniques to analyze employees’ reviews.  Our goal is to predict an overall measure of whether employees are satisfied or not, using other information from the reviews, such as employer attitudes towards upper management.  We also use predictive analysis to determine which features are more helpful in determining an employee’s overall job satisfaction.  Finally, we analyze which prediction algorithm provides the most accurate predictions.  We find the percentage of true positives we correctly identify in the holdout sample is 97.4%, while the percentage of true negatives correctly identified is 72.5%.
Feminismo
Authors: Lara Ariane Corrêa de , Ningeliski Adriane de Oliveira
Published: June 2021

O feminismo é um movimento social, político e econômico que luta por direitos iguais entre mulheres e homens. Discute o empoderamento feminino, sororidade e a experiência subjetiva entre mulheres. É uma aliança na qual todas são irmãs nas batalhas contra a opressão masculina e patriarcal. Também é uma forma de entender, discutir e combater a cultura do estupro, que culpabiliza as vítimas de violência sexual, sendo uma forma de conscientização social. O objetivo do presente estudo é demonstrar como o feminismo é uma forte opção para a desmitificação do crime de estupro e para a educação de jovens para ter o respeito necessário para com as mulheres. A metodologia utilizada é dedutiva, pois o tema é pertinente, pois o Brasil tem elevados índices de violência sexual contra as mulheres e este crime é até mesmo incentivado nas redes sociais, onde há páginas específicas para destilar o ódio às mulheres. O desrespeito pela condição da mulher como um ser humano é uma das principais causas da cultura do estupro e o feminismo luta para desconstruir a ideia de que a mulher nasceu para servir e que não possui quaisquer direitos. Luta para que seja reconhecida a mulher a sua dignidade e seus direitos.
Gestão democrática no contexto escolar e político brasileiro
Authors: Santos Jonatan Gomes dos , Canto Vânia Carla do
Published: June 2021

Na atual conjuntura da sociedade brasileira, refletir as possibilidades e os desafios de uma gestão escolar democrática torna-se necessário, principalmente, quando pensamos que cada escola é única e possui necessidades que se relacionam com o contexto no qual encontra-se inserida. Por isso, contar com a participação de toda comunidade escolar importa, tanto na constituição do processo de inclusão, do combate a evasão, quanto na constituição de alternativas metodológicas adequadas necessárias para lidar com a realidade escolar. Para tanto, apresenta-se um breve histórico sobre a gestão escolar no Brasil, pontuando suas implicações, possibilidades e desafios, de forma a refletir sobre esse assunto no decorrer da história, de modo que, seja possível repensar e analisar, no atual contexto, suas práticas e conceitos. Com base em pesquisas bibliográficas, visa-se confirmar a liderança do gestor e sua capacidade de intervir e compartilhar suas ações com a comunidade escolar com o intuito de garantir um ensino de qualidade ao educando. Assim, pensar a gestão democrática desemboca na constituição de um ambiente que preza pela coletividade onde todos os envolvidos são parceiros no processo de elaboração do Projeto Político Pedagógico, ou seja, se envolvem diretamente com a responsabilidade de construir coletivamente a escola.

Published: June 2021

The ubiquitin-proteasome system modifies different cellular and protein functions. Its dysregulation may lead to disrupted proteostasis associated with multiple pathologies and aging. Pharmacological regulation of proteasome functions is already an important part of the treatment of several diseases. 1,4-dihydropyridine (1,4-DHP) derivatives possess different pharmacological activities, including antiaging and neuroprotective. The aim of this study was to investigate the effects of several 1,4-DHP derivatives on mRNA expression levels of proteasomal genes Psma3, Psmb5, and Psmc6 in several organs of rats. Rats were treated with metcarbatone, etcarbatone, glutapyrone, styrylcarbatone, AV-153-Na, or AV-153-Ca per os for three days. mRNA expression levels were determined with real-time polymerase chain reaction (PCR). For AV-153-Na and AV-153-Ca, we also determined the expression of the Psma6 gene. In the kidney, metcarbatone, etcarbatone, styrylcarbatone, and AV-153-Na increased the expression of all analysed genes. Glutapyrone increased the expression of Psmb5 and Psmc6 but did not affect the expression of Psma3. In the blood, glutapyrone increased Psmb5 expression. In the liver, AV-153-Na increased the expression of Psma6 and Psmc6 but lowered the expression of Psmb5, while AV-153-Ca only increased Psma6 expression. The ability of 1,4-DHP derivatives to increase the expression of proteasome subunit genes might hold a therapeutic potential in conditions associated with impaired proteasomal functions, but further research is needed.

Published: June 2021

Occupational and sports medicine (OSM) education is poorly represented in Croatian university undergraduate medical curricula. Zagreb University medical students are required to take OSM classes for a week on their final year of studies. The classes are organised around team-based learning (TBL). Given that students who attend TBL classes have significantly higher exam scores than students who take lectures ex cathedra, the aim of this study was to assess students’ knowledge and attitudes immediately after TBL OSM classes. This cross-sectional study included 162 final-year Zagreb University School of Medicine students taking TBL classes in OSM in the academic year of 2019/2020. They were recruited from 30 September 2019 to 4 March 2020. Participants filled in a 20-item questionnaire compiled by the authors and adapted to the Croatian legislation. Their answers demonstrated positive attitude toward OSM classes and negative attitude toward occupational medicine practice and OSM specialty. They showed moderate interest only for the job of sports physician. Even though they showed sufficient knowledge of OSM immediately after the course was completed, they were moderately satisfied with their knowledge. Our findings call for rethinking the practical aspects of teaching OSM classes in order to promote OSM practice among medical students or at least raise awareness about the importance of prevention of numerous work or sport-related disorders.

Authors: Ham Andrés , Maldonado Darío , Guzmán-Gutiérrez Carlos Santiago
Published: June 2021

This paper characterizes the labor market of youth in Colombia from 2008 to 2017. We estimate labor market indicators for individuals aged between 14 and 28 years using microdata from Colombia's household surveys over the study period. Our estimates document the main patterns and trends in the labor market of youth in labor force participation, employment, unemployment, informality, and earnings. We compare these statistics with the same indicators of adults (individuals aged between 29 and 65 years), and explore differences in characteristics within youth such as gender, region, educational attainment, socioeconomic status (SES), and experience. Results indicate that participation rate of young Colombians have increased in recent years, but are mainly employed in low-quality jobs namely unsalaried and informal. We also document marked inequalities in labor market outcomes across youth characteristics. We provide a series of recommendations to guide future youth labor policy based on these estimates as well as the critical analysis of recent youth policies in Colombia.
Primary care research – influencing and implementing into policy
Authors: Kendall Sally
Published: June 2021

This editorial describes how research in primary health care can be used to influence policy. It draws on previous literature to give an example from the UK of how research in one part of primary care, the health-visiting service, has endeavoured to use evidence to influence policy and practice. The editorial considers frameworks for policy implementation such as Bardach’s eight phase approach and concepts that can inform policy implementation such as Lipsky’s Street-Level Bureaucrat approach.
Promoting EU values in international agreements
Authors: Eva JANČÍKOVÁ , Janka PÁSZTOROVÁ
Published: June 2021

Within the framework of external relations policy as a subject of international law, the European Union has the right to negotiate, conclude, amend and terminate international agreements on its own behalf, i.e., it has competences granted on it in this area by the Treaties. International agreements concluded at European level are results of an agreement between parties and belong to the sources of European Union Law. Current practice in concluding international agreements at the level of the European Union proves that trade and investment agreements contain provisions concerning civil society, labor relations andenvironment. The scientific study opens a discussion on a new model of international agreements which, in addition to trade relations, contain provisions on the social status of employees of the parties and on sustainable development. This new model of international treaties is supported by all Member States. The systems analysis shows that the European Union no longer acts as an economic-integration grouping towards third countries, but as an international organization that takes into account high level of environmental protection and the protection of employees' industrial relations.
Competition issues including in the international agreements of the Eropean Union
Authors: Daniela NOVÁČKOVÁ , Jana VNUKOVÁ
Published: June 2021

The scientific thesis aims at theoretical definition and analysis of provisions on competition policy in selected international agreements, which affects the development of fair international business. Fair competition works effectively if entrepreneurs at the market can make their business decisions independently, while there has to be a legal framework applicable to protect the rights of competitors. At the international level there are several legal instruments applicable, which have a positive effect on fair competition among competitors in the market. International agreements concluded at the level of the EuropeanUnion with non-member countries contain provisions on healthy competition. Our intentionis to identify those international agreements containing competition provisions that affect thebehavior of entrepreneurs operating in international markets and obliged to respect competition rules, as they aim to achieve economic benefits. The European Union is undoubtedly involved in the process of global competition protection.

Authors: Maryna GLUKH , Viktoriia SERDIUK , Pavlo SELEZEN , Anton BABENKO
Published: June 2021

Interpretation of double taxation treaties is of utmost importance for application of their norms according to the criteria of good faith in compliance with the provisions of the Vienna Convention on the Law of Treaties. At the same time, there is no consensus in understanding the role of the OECD MC and its Commentaries as means of interpretation of double taxation treaties. As it is demonstrated on the basis of the development of court practice in Ukraine, the present situation does not add certainty to implementation of double taxation treaties and might even have the negative effect on investment climate in a state of source of income. The article does also contain the ways of improvement of application of the OECD MC and its Commentaries during the implementation of double taxation treaties of Ukraine including (1)preparation of the letter on issue of application of the OECD MC and its Commentaries as a source of interpretation of double taxation treaties by the Supreme Court of Ukraine, (2) granting of the technical assistance to tax authorities of Ukrainein the area of application of double taxation treaties in accordance with the international standards such as the OECD MC and its Commentaries and (3) translation of the OECD MC and its Commentaries into Ukrainian language.

Terdapat beberapa petirtaan di Jawa Tengah yang merupakan bagian integral dari sebuah candi. Fenomena ini dapat dilihat pada tata ruang Candi Ngempon yang terletak tidak jauh dari Petirtaan Derekan. Penelitian ini bertujuan untuk menganalisis penerapan kitab Manasara-Silpasastra yang memengaruhi tata letak petirtaan dengan suatu candi sebagai satu bagian integral. Penelitian ini dilakukan dengan analisis data sekunder yang diperoleh dari studi pustaka dan wawancara. Data sekunder tersebut kemudian menjadi dasar dilakukannya crosscheck dengan melakukan pengamatan lapangan. Dari metode tersebut diperoleh kesimpulan bahwa tata ruang Pechaka dalam Manasara[1]Silpasastra diduga menjadi dasar pemilihan letak Candi Ngempon yang berada di sisi timur laut Petirtaan Derekan sehingga menunjukan adanya penerapan kitab Manasara-Silpasastra dalam kasus ini
 
There are several petirtaans or bathing structures in Central Java that become an integral part of a temple complex. Such a phenomenon can be seen in the layout of Ngempon Temple and Petirtaan Derekan which are located close to each other. This research aims to analyze the implementation of the book of Manasara-Silpasastra in the layout of Petirtaan Derekan and Ngempon Temple as an integrated whole. The research was carried out by analyzing secondary data obtained from a literature review and interviews. The secondary data were corroborated with data obtained from field observations. Results of the analysis indicate that the layout of Pechaka in Manasara-Silpasastra might become the basis for the positioning of Ngempon Temple at the northeast of Petirtaan Derekan. This shows that the book of Manasara-Silpasastra might be implemented in the layout of the complex of Ngempon temple.
"Man kan inte bara gympa sig igenom ämnet"
Authors: Norberg Anna-Maija
Published: June 2021

This article investigates how five teachers in Physical Education and Health (PEH) draw on different discourses of legitimation and delegitimation of writing practices in PEH. The data consist of transcripts of audio recordings of interviews with the five teachers. Firstly, the recordings were analyzed using van Leeuwen’s (2007) legitimation framework. Secondly, the lexical choices were analyzed to identify different discourses of writing (Ivanič, 2004). Results show that a social practices discourse dominates in the data analyzed, most commonly realized through a rationalization type of legitimation. Students’ linguistic difficulties or unwillingness to write in PEH, i.e. writing with obstacles, is another discourse of writing found in the data. Overall, the teachers tend to legitimate writing practices but report on students’ delegitimation of the same practices, which teachers need to manage. The use of texts is legitimated as practical, timesaving and a recognized tool for instruction and assessment. Writing practices and the use of texts can contribute to the raise the status of PEH and reach long-term goals in PEH and for students’ learning at large. On the other hand, writing and text practices steal time from the core content in PEH and may not suit students who are successful in other parts of PEH.

Published: June 2021

A big commercial and entertainment complex called Meydan One, designed by the American architectural firm AE7, is currently under construction in Dubai, UAE. The complex consists of a big shopping mall surrounded by different towers for offices and hotels, a ski slope, gardens with lagoons, etc.

The mall has a dominant long and wide corridor called the “canyon” which is crossed by 7 steel footbridges, the subject of this paper. The bridges share aesthetic traits amongst another, as well as with the roof over the canyon, creating a unified whole.

The paper outlines the mall as the context of the footbridges. Their design and structure are then explained with focus on how a single structural system is adapted to different situations. The paper concludes with describing the sophisticated erection sequence necessitated by the use of steel plates as tensile members.

Nephrotoxicity Risk of Cyclophosphamide in Lupus Model
Authors: Indriyanti Niken
Published: June 2021

Cyclophosphamide is one of the standard therapies for lupus, especially lupus nephritis based on its immunosuppressive effect. However, cyclophosphamide is also known as a nephrotoxic agent. Therefore, this research was aimed to measure the effect of cyclophosphamide at the dose that comparable to the human dose of 1 mg/kg BW on the kidney of lupus mice induced by means of 2,6,10,14-tetramethylpentadecane (TMPD). In this research, the IL-6 as a pro-inflammatory cytokine was tested by using flow cytometry method. In addition, the structural damage of the kidney tissues was assessed by means of Moroni’s kidney organ scoring method for lupus. The result showed that cyclophosphamide reduced the IL-6 significantly with the value of 36.72±22.79% for the TMPD-treated group; 32.59±9.97% for the cyclophosphamide group; and 30.25±4.48% for the naïve group. Moreover, the damages of the kidney tissues on the cyclophosphamide group were more severe than the TMPD-treated group. In conclusion, despite its anti-inflammatory effect which is useful for lupus, cyclophosphamide has a severe nephrotoxic effect which harms the patient. The effects may be a cause of the long interval use of cyclophosphamide. It can be a consideration for the further research and the next revision of the guideline for lupus nephritis treatment.
Comparative Computational Analysis of SARSCoV-2 Nucleocapsid Epitope with Taxonomically Related Corona Viruses
Authors: ELKHOLY SHEREEN
Published: June 2021

Several research lines are currently ongoing to address the multitude of facets of the pandemic COVID-19. In line with the One-Health concept, extending the target of the studies to the animals which humans are continuously interacting with may favor a better understanding of the SARS-CoV-2 Biology and pathogenetic mechanisms; thus, helping to adopt the most suitable containment measures. The last two decades have already faced severe manifestations of the coronavirus infection in both humans and animals, thus, circulating epitopes from previous outbreaks might confer partial protection from SARS-CoV-2 infections. In the present study, we provide computational analysis of the major nucleocapsid protein epitopes and compare them with the homologues of taxonomically-related coronaviruses with tropism for animal species that are closely inter-related with the human being population all over the world. Protein sequence alignment provides evidence of high sequence homology for some of the investigated proteins. Moreover, the way the receptor binding domains of the nucleocapsid epitopes interact with their specific proteins is different from the closely related viruses. These evidences provide a molecular structural rationale for a potential role in conferring protection from SARS-CoV-2 infection and identifying potential candidates for the development of diagnostic tools and prophylactic- oriented strategies.

Published: June 2021

Sweet cherry fruits are perishable goods, and the fruit quality can additionally be affected by fungal diseases, primarily by Monilinia species. A promising method for fungal disease control in storage is the use of essential oils. Three different methods of wild oregano essential oil application were tested: incorporation (5% dilution), exposing to the vapor phase (0.08 and 0.16 µl/cm3), and fruit immersion in 5% dilution. Incorporation of essential oil showed the strongest inhibitory effect on Monilinia laxa in both tested cultivars (Regina and Karina). The vapor phase had the same effect on inhibition of Monilinia laxa at both concentrations on cold-stored fruits of cv. Regina after incubation at room temperature, while on cv. Karina, higher concentration showed a stronger inhibitory effect. The immersion in EO dilution caused phytotoxic changes on the fruit skin. Necrosis development rates significantly increased after the cold storage period terminated.

Authors: Fedotova Natal'ya
Published: June 2021

This article examines the transformation of cultural function of the libraries of pedagogical universities, considering challenges and changes in the digital educational environment. Leaning on the modern scientific research on creation and content arrangement of web resources, the author analyzes the libraries of 37 pedagogical universities nationwide, as well as interrelation between cultural function and thematic headings. The object of this research is the description of peculiarities of implementing cultural function of the library in the common information space of an educational institution. The subject of this research is the virtual book exhibitions as an instrument of promoting publishing projects and a synthesis of traditional and innovative ways of conveying information to the readers. The main conclusions are as follows: in implementation of cultural function, the university library pursues the goal development of spiritual and moral personality traits. The libraries make a considerable contribution to the becoming and socialization of an individual by preserving and augmenting cultural wealth of literary sources. The implementation of cultural function should take into account the abundance and availability of information in modern world. The stylistics of messages and sources does not always correspond to generally accepted norms and morals. The libraries also aim to draw interest to cultural environment and develop the in skills of working with literary sources among the readers, as well as form a deliberate cultural assessment of the surrounding reality.
The vampires of A. V. Ivanov in light of the gothic tradition of Russian Literature
Authors: Kulikova Daria Leonidovna
Published: June 2021

The object of this research is the novel “Food Block” by A. V. Ivanov and the realization of aesthetics of the horror genre therein. The goal is to establish correlation between the gothic tradition of Russian literature and modern horror literature based on the works of the indicated authors. The article examines the influence of the gothic romantic tradition upon composition and imaginary system of A. K. Tolstoy’s novella. The material of A. V. Ivanov’s novel indicates resorting to the literary tradition on the level of composition and individual images; while overall, the historical experience accumulated by the genre over the decades and significant impact of cinematography manifested on the level of cinematographic techniques. The conclusion is made that in the novel by A. V. Ivanov, the mystical attributes of vampirism, which coincide with the pioneer symbolism, have political implications, which contradicts the horror traditions in gothics. Novellas “The Vampire” and" The Family of the Vourdalak” are the result of accumulation of gothic motifs, such as family curse, mystical house, dream, and portrait that came alive. Comparison of the techniques of creating horror literature allows tracing the paths of literary evolution, and formulating conclusions on modernization of the genre at the present stage. The novelty of this research is define by insufficient research of the topic of typological and genetic links between gothic and modern horror, namely in the works of A. V. Ivanov.

Objetivo: Descrever e discutir os parâmetros do suporte ventilatório de pacientes com COVID-19, assim como os critérios e métodos utilizados para o desmame da Ventilação Mecânica Invasiva (VMI). Revisão bibliográfica: De acordo com a análise literária, o modo ventilação com pressão controlada com volume corrente baixo está dentro dos parâmetros iniciais recomendados para a VMI. O desmame, por sua vez, engloba fatores individuais, como a carga e a capacidade do sistema respiratório, e os aspectos psicológicos, físicos e nutricionais. Em pacientes com COVID-19, os critérios tradicionais de extubação permanecem os mesmos, sendo o processo feito de forma gradual, englobando a redução gradativa do nível de Pressão Expiratória Final Positiva (PEEP) ao mesmo tempo em que é feita a checagem das metas de oxigenação. Além disso, a fisioterapia respiratória se faz necessária antes e após a realização da extubação. Considerações finais: Apesar da escassez de estudos e a falta de consenso em relação às condutas no manejo da COVID-19, estabeleceu-se um ponto de partida efetivo no tratamento de tais pacientes no que diz respeito aos parâmetros da VMI e ao desmame de tal terapia, culminando no sucesso de tais intervenções.

В статье дана сравнительная оценка окисленной поверхности монолитных и пористых сплавов на основе никелида титана после отжига на воздухе при 1000 °С. Представлен анализ стойкости поверхности пористого СВС никелида титана сопротивляться высокотемпературному окислению на воздухе при 1000 °С на основе исследований структурно-фазовых состояний приповерхностных слоев. Установлено, что для монолитных и пористых сплавов на основе никелида титана, полученных разными методами, отжиг при 1000 °С на воздухе приводит к разным структурно-фазовым состояниям в приповерхностных слоях. На окисленной поверхности монолитного сплава на основе никелида титана обнаружено многофазное состояние: диоксид титана TiO2, карбид TiC, оксид никеля NiO и никель Ni. Установлено, что окисная пленка толщиной 8¸10 мкм имеет градиентное строение с разными структурами: пористой, зернистой и островковой. На поверхности окисленного пористого спеченного сплава на основе никелида титана кроме фаз диоксида титана обнаружен свободный никель и его оксид. Высокотемпературный отжиг на воздухе приводит к образованию рыхлого окисленного слоя толщиной до 50¸60 мкм. Установлено, что на поверхности пористого образца, полученного методом высокотемпературного синтеза, содержание Ni значительно меньше, по сравнению с пористымми спеченными образцами из сплава на основе никелида титана. Изучение особенностей структурно-фазовых состояний приповерхностных слоев показало, что высокотемпературному окислению наиболее подвержены спеченные и монолитные сплавы на основе никелида титана из-за большей незащищенной реакционной поверхности, где на поверхности обнаружены оксид никеля и свободный никель (Ni, NiO). Показано, что наличие защитного тонкого и плотного оксикарбонитридного поверхностного слоя на основе соединения Ti4Ni2O(N,C) в пористом сплаве, полученного методом высокотемпературного синтеза, значительно уменьшает интенсивность окисления по сравнению с другими исследуемыми сплавами на основе никелида титана.

Методом молекулярной динамики проведено исследование кривых напряжение-деформация чистого кристалла никеля при сдвиге вдоль направления <111> в зависимости от температуры, скорости деформирования, размера моделируемой расчетной ячейки. Сдвиг в модели инициировался путем смещения атомов в верхней и нижней областях расчетной ячейки в противоположных направлениях. Данные области в процессе компьютерного эксперимента перемещалась как единое целое. Для других границ расчетной ячейки использовались периодические граничные условия. Для описания межатомных взаимодействий использовались многочастичные потенциалы Клери-Росато, построенные в приближении сильной связи. Показано, что скорость сдвига менее 20 м/с слабо влияет на теоретическую прочность при постоянной температуре. С ростом температуры формирование дислокаций и пластическая деформация в идеальных кристаллах начиналась при меньших значениях деформации. Кроме этого, температура в значительной степени влияла на наклон зависимостей напряжение-деформация в упругой области, что обусловлено температурной зависимостью модуля сдвига. Полученные в работе температурные зависимости теоретической прочности и модуля сдвига имели вид, близкий к линейному, что согласуется с результатами реальных экспериментов. Найденное в модели значение модуля сдвига для нормальной температуры также оказалось близко к справочному. При рассматриваемом типе нагружения, сдвиге вдоль направления <111>, дислокации возникали в двух системах скольжения. При достаточно больших значениях деформации дислокации из одной системы скольжения участвовали в образовании деформационных двойников. Дислокации из другой системы останавливались такими двойниками, которые, как известно, наряду с границами зерен являются эффективными стопорами движущихся дислокаций.

Построение термодинамических компьютерных моделей реальных сплавов базируется в первую очередь на выборе потенциала взаимодействия частиц. Зачастую от выбора потенциала во многом зависит конечный результат. Потенциал должен качественно и максимально точно численно описывать основные свойства рассматриваемых материалов. Целью данной работы является численный анализ свойств кристаллов Ni3Al и Pt3Al при использовании потенциалов, полученных методом погруженного атома. Рассматриваются классические потенциалы типа EAM, а также модифицированные потенциалы MEAM с учетом направленных связей. Произведены расчеты параметров решетки, фононных спектров, упругих констант, а также температур плавления предложенных ГЦК интерметаллидов со сверхструктурой L12. Максимально точное описание свойств кристаллов потенциалами позволяет строить реалистичные термодинамические модели, обладающие необходимой степенью достоверности при изучении локализованных состояний кристаллических решеток. Рассматриваемые в работе сплавы имеют широкое применение, в том числе при интенсивных внешних воздействиях. Это приводит к проявлению нелинейности связей и формированию различных локализованных состояний как в объеме кристаллов, так и на его поверхности. В частности, возможно формирование уединенных вол, нелинейных локализованных мод, дефектных структур. Полученные результаты свидетельствуют о том, что все рассмотренные потенциалы удовлетворительно описывают основные свойства и могут быть использованы при исследовании динамики решетки в объеме кристалла. В тоже время при исследовании поверхностных эффектов и при граничных параметрах температуры и давления предпочтительными выглядят потенциалы MEAM.

На примере высоколегированного титанового сплава ВТ22 рассмотрено влияние температуры и деформации при прокатке, а также статического отжига на кинетику газонасыщения поверхности листовых полуфабрикатов. Выявлено, что в процессе прокатки толщина газонасыщенного слоя практически не меняется, а количество α-фазы в нем увеличивается. Прокатка листа приводит к формированию металлографической текстуры в газонасыщенном слое. Установлено, что наиболее интенсивно газонасыщение происходит при нагреве в β-области в течение первого часа. Структура газонасыщенного слоя при переходе через температурную границу полиморфного превращения претерпевает существенные изменения. После отжига в β-области газонасыщенный слой представляет собой выделения пластинчатой α-фазы. Отжиг в (α+β)-области приводит к пластинчатым выделениям α-фазы, формирующих морфологию корзиночного плетения. Снижение температуры прокатки до температурного интервала (α+β)-области приводит к заметному утонению газонасыщенного слоя на поверхности листового полуфабриката. Увеличение выдержки замедляет в дальнейшем скорость окисления. Глубина газонасыщенного слоя в зависимости от температуры и времени выдержки может достигать величины от 0,11 до 0,41 мм.

Authors: Thuy Le Thi Thanh , Lan Nguyen Thi
Published: June 2021

N-doped TiO2 nanomaterials were prepared with the sol-gel method. The structure and properties of the materials were characterized by using XRD, UV-Vis, SEM, EDX, and IR techniques. The optimal dose of ammonium chloride for doping is 600 mg. The optical absorption edge of N-TiO2 displays a redshift, and a long tail occurs in the presence of nitrogen in the material. Thereby, N-TiO2 may exhibit improved absorption properties under visible light and the solar irradiation. The photocatalytic activity was investigated on the degradation of rhodamine B. The optimal amount of the photocatalyst is 1.8 g/L under visible light.

The educational achievement in Indonesia is measured by implementing the National Examination or Ujian Nasional (UN). Throughout its implementation, the UN results shown unsatisfying results, including in mathematics subjects. This fact indicated that there are mathematics topics that are considered to be difficult for students. This study aimed to investigate the difficult topics of mathematics in Vocational High School (VHS) based on UN data. This study was a descriptive research with the quantitative approach by using the UN report results in the level of VHS from Center for Educational Assessment of the Ministry of Education and Culture in the period of 2008 to 2017 (ten years) as a research data source. Data analysis was carried out in a quantitative descriptive by mapping the mathematics topics based on proportion correct answers or “daya serap”. A topic was considered difficult if the proportion correct answer was less than 50%. The results showed that there were 14 difficult mathematics topics in the UN implementation at the VHS level from 2008 to 2017. These topics include the comparison of trigonometric functions, solid figure, limit, measure of data dispersion, permutation and combination, differential, area between two curves, a measure of central data tendentious, probability, logarithm, integral, sequence and series, linear program, and polar coordinates system. The implications of the research findings for learning practice and future research opportunities are discussed.

Assessment is part of the learning cycle, so that assessment cannot be separated from a learning activity. The Minister of Education and Culture said that the implementation of the 2020 National-Based School Examination will be carried out with exams held by schools. The exam is conducted to assess student competence and can be done in the form of a written test or a comprehensive assessment such as portfolios and assignments. This portfolio can later be done through group assignments, paper work, and so on. Researchers want to know the extent of school readiness, teachers' perceptions and knowledge of portfolio assessments, types / forms of portfolio assessments that have been carried out in schools, and constraints in implementing portfolio assessments. The research was carried out in superior junior high junior high schools in the the Special Region of Yogyakarta, namely SMPN 1 Bantul and SMPN 4 Pakem. The implementation of the portfolio assessment carried out at SMPN 1 Bantul and SMPN 4 Pakem went very well and was effective because it was supported by school members (school principals, educators, education staff, students, parents, and the community) through various policies and concrete actions carried out consistently and the seriousness of the school in supporting the program.

This paper presents the upcoming changes in the runway reporting format and the newly introduced SNOWTAM format. The aim of the paper is to draw comparisons between the current SNOWTAM format and the updated version applicable as of November 2021. The author analysed information from available documents published by the International Civil Aviation Organisation ICAO, which describe the general conditions adopted to the new runway condition reports formulations. Since the author is enrolled in his pilot training, his objective when writing this final thesis, was to understand the issue of the changes. From this knowledge he can benefit in his future carrier. The paper points out new formats of reports of airport movement areas reporting conditions. As the new reports and techniques of reporting have not been used in real conditions yet, the author based the paper on the ICAO standards and recommended practices, ICAO and EASA guidance material. Introduction of the new methodology is expected to provide a better understanding of reports informing about contamination on movement areas, to ensure more precise aeroplane performance calculations and enhance the safety.
