International Relations Theory and the Ukrainian War
Authors: Lebow Richard Ned
Published: July 2022

Drawing on my qualitative and quantitative research I show that the motives for war have changed in the course of the last four centuries, and that the causes of war and the responses of others to the use of force are shaped by society. Leaders who start wars rarely behave with the substantive and instrumental rationality assumed by realist and rationalist approaches. For this reason, historically they lose more than half wars than they start. After 1945, the frequency of failure rises to over 80 percent. Rationalists allow for miscalculation but attribute it to lack of information. In most wars, information was available beforehand that indicated, or certainly suggested, that the venture would not succeed militarily or fail to achieve its political goals. The war in Ukraine is a case in point.
Symmetry in World-Historic Perspective: Reply to Lynch
Authors: Fuller Steve
Published: July 2022

William Lynch has persistently questioned the politics underlying my appeal to science and technology studies’ flagship symmetry principle. He believes that it licenses the worst features of the ‘post-truth condition’. I respond in two parts, the first facing the future and the second facing the past. In the first part, I argue that the symmetry principle will be crucial in decisions that society will increasingly need to make concerning the inclusion of animals and machines on grounds of sentience, consciousness, intelligence, etc. In the second part, I argue that the symmetry principle has been in fact at the core of the ‘justice as fairness’ idea that has been at the core of both liberal and socialist democracies. Difficulties start once the means of expression and communication are made widely available and the standards of fairness are subject to continual questioning and renegotiation.
How to Do Things with Justice: Professor Rawls, 1962–1971
Authors: Baranowski Brad
Published: July 2022

Understanding the social bases of what John Rawls meant by justice requires understanding a central part of Rawls’s professional life: his role as a teacher. As this essay shows, Rawls’s approach to teaching was not ancillary to his approach to heady philosophical issues like the justification of moral reasoning. Rather, there’s an ethic that runs through Rawls’s work, one focused on deliberation and consensus-seeking, and one whose strengths and weaknesses are easiest to see when you examine his teaching.

Analytisch oder holistisch? Welchen Einfluss hat die Beurteilungsmethode auf das Verhalten von Beurteilenden und die Ergebnisse von Prüfungsteilnehmenden?
Authors: Korflür Denis , Marks Daniela , Weiss-Motz Frank
Published: July 2022

Der Beitrag präsentiert eine Studie, in der analytische und holistische Einstufungen von Teilnehmendenleistungen im Prüfungsteil Schreiben des digitalen TestDaF untersucht wurden. Dabei wurde der Frage nachgegangen, welchen Einfluss das Beurteilungsverfahren auf die Ergebnisse der Teilnehmenden hat und inwieweit die Ergebnisse zweier unterschiedlicher Verfahren vergleichbar sind. In einer ersten Beurteilungsphase wurden die Leistungen von erfahrenen Beurteilenden analytisch anhand einer 6-stufigen Beurteilungsskala nach jeweils sechs Kriterien bewertet. In der nächsten Phase wendeten neun Beurteilende aus der ersten (analytischen) Phase der Studie die neue (holistische) Skala bei der Bewertung derselben Leistungen an. In beiden Phasen wurden Unterschiede in der Qualität der Einstufungen nach beiden Beurteilungsmethoden untersucht und sowohl die Inter-Rater- als auch die Intra-Rater-Reliabilität für beide Beurteilungsmethoden separat berechnet. Die Analysen zeigten keine signifikanten Unterschiede zwischen den Beurteilungsmethoden hinsichtlich des Verhaltens der Beurteilenden. Die Anwendung des holistischen Verfahrens führte allerdings zu tendenziell niedrigeren Einstufungen.
Cavitation resistance of Stellite 21 coatings tungsten inert gas (TIG) deposited onto duplex stainless steel X2CrNiMoN22-5-3
Authors: Mitelea Ion , Bordeaşu Ilare , Mutaşcu Daniel , Buzdugan Dragos , Crăciunescu Corneliu Marius
Published: July 2022

Cobalt-based alloys, called Stellite, have a microstructure consisting of complex carbides dispersed in a Co-based solid solution matrix. These alloys are resistant to corrosion, erosion through cavitation, abrasive, and sliding wear. To increase the erosion resistance through cavitation, hardfacing of the stainless steel duplex X2CrNiMoN22-5-3 with Stellite 21 alloy was performed using the pulsed tungsten inert gas (TIG) process. The positive effects of the hardfacing process are the low heat input, reduced distortions, controlled volume of the weld, and reduced susceptibility to hot cracking. The effect of dilution is essential for the quality of the deposited layers and, in this sense, the TIG pulsed current welding process was performed to reduce the excess linear energy and implicitly the substrate melting. Iron dilution levels were in the range between 5.9 and 6.1. The higher Fe content in the first layer does not significantly reduce its hardness or wear resistance through erosion cavitation. Compared with the substrate material, the cavity erosion resistance increases 7 to 11 times even in the first layer hardened by the TIG pulsed current welding process.
Effects of filler material selection on the microstructural, mechanical and corrosion properties of TIG welded AISI/SAE 304L stainless steel sheets and rings
Authors: Akgül Oğuz , Başyiğit Aziz Barış
Published: July 2022

Austenitic stainless steels are mainly preferred especially for resistance to aggressive oxidizing medias and high temperature applications such as equipments and mechanical parts which are used in defense and conventional industries. In this study; 3 mm thick 304L austenitic stainless steel sheets and rings are joined to each other by using Tungsten Inert Gas welding method under pure argon shielding gas with ER316L and ER2209 filler metals. Weld metals and heat-affected zones of welded joints were examined by metallurgical and scanning electron microscopes. Microhardness, tensile and Charpy impact tests of weld regions are investigated. It has been determined that the filler metals have dominantly changed the microstructure of weld metals. The microhardness values of the welded samples joined with ER2209 filler metal was lower than the sample joined with ER316L filler metal in weld metal regions. Besides, corrosion tests indicated that the corrosion rates of welded samples joined with ER2209 filler metal is lower than the samples joined with ER316L filler metal.

Chitosan nanoparticles encapsulated into PLA/gelatin fibers for bFGF delivery
Authors: Ghasemzaie Niloofar , Hadjizadeh Afra , Niknejad Hassan
Published: July 2022

Electrospinning is a trendy method because of the ease of use and the high surface-to-volume ratio. The mechanical and biological properties of polylactic acid (PLA) make it one of the most enticing polymers. Gelatin and PLA together are thought to enhance cellular behavior and hydrophilicity of scaffolds. Furthermore, chitosan nanoparticles (CNPs) can be incorporated into PLA fibers to achieve controlled growth factor release. This study utilized PLA–gelatin nanofibrous scaffolds in which CNPs were encapsulated within PLA fibers to achieve a controlled release of basic fibroblast growth factor (bFGF). To produce CNPs, a simple ionic gelation reaction was used. The optimal diameter of CNPs was determined by investigating chitosan to tricalciumphosphatesodium (TPP) ratio and TPP concentration. Using a spectrophotometer, we measured the release rate of bFGF from CNPS and scaffolds. Images from a scanning electron microscope (SEM) were used to assess the effect of various concentrations of PLA and gelatin on fiber diameter. The results showed that PLA–gelatin scaffolds could stimulate the release of growth factors and promote cell proliferation. Using a two-jet electrospinning device to produce PLA–gelatin fibers in combination with CNPs incorporated within PLA fibers to release the bFGF growth factor is the novelty of this study.
Changes in the conception of marriage in China
Authors: Dai Huiqiaoxian
Published: July 2022

Chinese modernization influenced public views on marriage. Improved education, democratization, women's emancipation, economic development, and the new emphasis on one’s self-actualization were the main factors that influenced marriage relationships. Changing attitudes and behaviors are a challenge to societal stability. Young people seem to turn away from previous traditions, conceiving marriage as an economic alliance, and look for romantic love and intimacy. Using the data from the National Bureau of Standards (NBS) of China, this paper explores the resulting gender disparities, the improvements in education and the parallel increase in divorce rates, decrease in marriage rates and birth rates, as indicators of the changing conceptions on intimate relationships and marriage.
Study of Strength and Durability Characteristics of Concrete Mixes Made by Unwashed Sea Sand as Fine Aggregates
Authors: Rafi Muhammad Masood , Bhutto Muhammad Aslam , Aziz Tariq
Published: July 2022

The use of sea sand in concrete can reduce burden on river sand, which can help in protecting the environment. Although testing of concrete mixes using sea sand, sea water, or both has been reported in the existing literature, studies based on the use of unwashed sea sand are limited. Further, it has been reported in the literature that the concrete properties are influenced by the origin of sea sand. This paper presents experimental studies to investigate suitability of unwashed sea sand as fine aggregates in structural concrete. The properties of concrete mixes made by four levels of sea sand addition were investigated from the perspective of strength and durability in this paper. These levels of river sand replacement include 30 % (designated as 30SS), 50 % (designated as 50SS), 70 % (designated as 70SS), and 100 % (designated as 100SS). Mixes made with river sand were used as control mixes (designated as 0SS). All the employed mixes provided the required compressive strength at 28 days. Similar permeability characteristics were observed for the 0SS and 30SS mixes. Chloride ion penetration of the 70SS and 100SS mixes increased with time, whereas it reduced for the other mixes. Water absorption and permeability of these aforementioned mixes were also higher compared to the other mixes. The corrosion and aggregate-silica reaction potential were not indicated by the testing of the employed mixes after 1 year.
Development of a Real-Time Monitoring and Calculation Method for TBM Disc-Cutter’s Cutting Force in Complex Ground
Authors: Huang Xing , Wang Shaohua , Liu Quansheng , Wang Xinyu , Liu Bin , Zhang Xiaobo
Published: July 2022

Cutting force is an essential parameter of the operating state of tunneling boring machines. In this study, a real-time cutting force monitoring method is proposed for widely used disc-cutters. A microcylindrical strain gauge is embedded in predrilled small boreholes in the bottom and side surface of the two C-shaped cushion blocks on the cutter saddle. The strain gauges are protected by a glue seal, and the sensor leads are protected using a groove and covered by wear-resistant steel. The strain is measured using a wireless strain node and transmitted from the strain node to the wireless gateway connected to a computer. Then, the strain-force relationship of the cushion block is fitted using a laboratory static calibration test. The load on the cushion block is calculated based on the measured cushion block strain. Subsequently, considering the cutter system’s vibration, a multi-degree-of-freedom coupling vibration differential equation of the cutter system is established. The mass matrix, stiffness matrix, and damping matrix of the cutter system are also determined. Finally, a Wilson-θ inverse analysis method is put forward to calculate the cutter’s external load. The developed real-time cutting force monitoring method will not affect cutter replacement, and the cushion block equipped with sensors can be reused. The cutting force identification method, which considers the cutter system vibration, is rigorous in theory, and a useful numerical inverse analysis calculation method is provided.
An Investigation of Unidirectional Liquid Moisture Transport Performance Evaluation of Textile Materials Based on Double-Sided Imaging

Published: July 2022

The interaction between water and fabric is critical in the physiological comfort of garments. However, it is still practically challenging to evaluate textiles with continuous directional liquid moisture transport and outstanding prevention of water penetration in the reverse direction. The traditional liquid moisture transmission test method has its shortcomings. In order to better evaluate the liquid water transport behaviors of fabric, a new method is proposed in this paper. A series of images of fabric wetting are acquired from two different perspectives through a self-made double-sided image acquisition device. At the same time, a suitable segmentation algorithm for the image sequence is proposed in this study. Finally, the index parameters of fabric wettability can be obtained, and the wettability process of fabric can be analyzed. The experimental results show that the method of double-sided imaging can obtain more comprehensive fabric wetting information. Combined with the existing image-processing algorithms, the double-sided imaging image acquisition system proposed in this paper can be used to form a complete evaluation system of fabric liquid moisture transport behaviors.
Study on Compressive Properties of Self-Healing Cement Paste Using Acoustic Emission and Digital Image Correlation

Published: July 2022

Self-healing microencapsulation is a subtle existence in cement mortar. Traditional mechanical test methods cannot comprehensively explain the failure mechanism and failure mode of microencapsulated self-healing cement mortar. Therefore, acoustic emission and digital image correlation are used to monitor the uniaxial compression failure process of self-healing cement paste. A kind of self-healing microcapsule was prepared with sodium silicate and expanded silicate cement as main core materials, and its state in mortar matrix was observed by a scanning electron microscope. Full-field strain and acoustic emission characteristics were obtained and used to analyze the failure mode and mechanism of microencapsulated self-healing cement mortar. The results show that the compressive strength decreases with the increase of the content of microcapsules. According to the analysis of acoustic emission characteristic signal curve, the compression failure process of cement mortar block without microcapsules can be clearly divided into three stages. The change of acoustic emission characteristics of cement mortar after adding microcapsules was captured. In the range of 1∼7 %, the acoustic emission hits first increase and then decrease. There are two main reasons for the change: one is the breakage of microcapsules and the other is that the addition of microcapsules changes the pore structure. At the same time, the whole process of compression failure is monitored by Digital Image correlation (DIC). It is found that the cement mortar test block with the appropriate amount of and excessive microcapsules has different failure modes. The results verify and supplement the results of acoustic emission monitoring. Based on the aforementioned indexes, the optimum content of microcapsule is 1∼3 %. The research results are of great significance to the design and engineering application of microcapsule self-healing concrete.

Many political and research agendas place the entrepreneurial subject at the epicentre of economic development. Our objective was to use a gender perspective to study asymmetries in the perception of entrepreneurship in two different but close geographic areas: Northern Morocco and Southern Spain. We conducted a survey of 1233 people in Spain and Morocco. In Morocco, the participants were (a) a sample of students from the Abdelmalek Essaadi University in the Tangier-Tetouan area and (b) a sample of university graduates living in the same area. In Spain, the participants were a sample of students from the University of Malaga (Spain). We administered a questionnaire on the participants' perceptions of entrepreneurship opportunities in their setting, their own social and political attitudes toward entrepreneurship, and their self-perception of their own entrepreneurial knowledge and skills. Our results confirm and expand on the trends described in international reports and the scientific literature. They also provide new data that may be of help in meeting the challenge posed by the gender gap in business entrepreneurship.

We use a storytelling approach in this study to convey our experiences as graduate students managing the triple pandemic of COVID-19, social unrest, and the mental health of doctoral students of color. We use the analytical practice of storytelling through testimonios to investigate how we navigate higher education institutions while enhancing our positionalities in the face of structural barriers and social challenges. We talk about our encounters with racism, discrimination, and power structures to demonstrate the influence of political and social pressures that exist as we navigate the doctoral program. We believe that if higher education administrators and educators are aware of the experiences of students of color navigating the laberinto of PhD programs, they can develop curriculum and support structures to help doctoral candidates thrive.
Religious diversity and cultural differences in the fase of generic manipulation
Authors:   Universidad Nacional de Educación a Distancia (UNED), Peláez Palmira
Published: July 2022

Multiculturalism and religious diversity, which in recent decades seem to have made their way into our societies, require an approach in which the different positions at stake are identified. Next, an attempt will be made to justify how cultural and religious peculiarities have more aspects in common than differences; a palpable affirmation in fields such as biotechnology and bioethics, facing the challenges of these techniques at the beginning of life. Highlighting the vision that the different world religions have of these techniques, taking into account that they do so from a westernized conception. Guaranteeing respect for human dignity, regardless of its social context and the territory in which it resides will be the objective of the Universal Declarations, as well as the implementation of distributive social justice, a principle that is unfulfilled when it is observed that the new treatments are applied in countries with a higher economic level and that research has been sponsored by pharmaceutical corporations that involve people from developing countries as the object of such research.
Changes in the Constitutional Matter Affecting the Structure of the Judiciary During the Regime of 19 May 1934

Published: July 2022

The article “Changes in the constitutional matter affecting the structure of the judiciary during the regime of 19 May 1934” covers the changes in Bulgaria when on 19 May 1934, after a successful coup, the political circle ‘Zveno’ and the Military Union came to power. The coup was carried out in drastic violation of the constitution. A number of reforms had been undertaken in the country, some of which affected the constitutional structure. Particularly serious were those in the field of Bulgarian judicial organisation. The coup was carried out without the participation of the tsar, but was legitimized by him. The participants in the May 19 coup considered it necessary to change the procedure for the installation of the National Assembly. The constitutional powers of the Grand National Assembly were taken away by the government. The electoral right and the right of association guaranteed by the Tarnovo Constitution were violated. Amendments were also made to the administrative-territorial division of the country, which were implemented by ignoring the Constitution, where the names of the territorial units are explicitly mentioned. All these changes, euphemistically called “renewal”, affected the judicial system as well. The government of Kimon Georgiev, on the basis of Article 47 of the Tarnovo Constitution, issued on 24 November 1934 the Decree-Law on the Structure of the Courts. Interestingly, the structure of the 1926 law was adopted. Most of its text was reproduced, and the additions made concern primarily the internal structuring of some chapters and the introduction of new paragraphs. It was a major reform of the Bulgarian judicial system.
Model państwa ukraińskiego w koncepcjach prawicowych środowisk politycznych okresu międzywojennego

Published: July 2022

The changes that took place at the end of the First World War significantly affected all spheres of society: economic, political relations, ideology, and culture. They took place in almost every state and, despite the differences in their course, had one thing in common: the desire of political elites to achieve stability as soon as possible. The democratic and liberal methods of governance that governments tried to use to meet this challenge proved ineffective. As a result, totalitarian and authoritarian sentiments intensified in political thought at the time. They manifested themselves in a search for new concepts of state systems that would guarantee rapid success in carrying out reforms and ensure the proper functioning of the entire state apparatus for the benefit of society. The most suitable ground for their establishment and implementation was in those European states that had lost the war or failed to overcome economic recession and political instability. Having restored its statehood in 1917–1920, Ukraine then lost it. Among its political elites, active debate erupted over the question of who was to blame. Leaders of the Ukrainian People’s Republic were severely criticized by rightwing circles, who accused them of making the democratic republic model of the state unviable, which resulted in the loss of national independence. As an alternative, they formulated their own vision of the future Ukrainian state that included totalitarian or authoritarian models of government, which were bring established in a number of European countries and proved effective in neutralizing the communist movement, strengthening the state apparatus and playing the part of main arbiter in the life of society. Theoretical substantiations of these concepts were reflected in the works of right-wing radical and conservative politicians – Dontsov, Stsiborsky, Lypynsky, Kuchabsky, and Nazaruk. The model of the Ukrainian state in the vision of the right-wing political circles of the interwar period generally reflected the tendencies of European political ideas at that time, with the difference that the issue of restoring its independence remained a priority.

The Message of the Polish Bishops to their German Brothers in Christ’s Pastoral Office of 18 November 1965 is a symbol of the process of Polish-German reconciliation. Its significance, however, goes far beyond the symbolic sphere, as this document changed the mutual perceptions of Poles and Germans; built the foundations of an understanding based on values such as dialogue, truth, ands; forgiveness, and changed the narrative in Poland about their Western neighbour. Research on this document has been conducted for over 40 years and is evidenced in the abundant literature on the topic. Thanks to inquiries in foreign archives, the source database has significantly expanded in recent years, including the finding of the manuscript of the original version of the Message prepared by Archbishop Bolesław Kominek. Unfortunately, in the article devoted to the Message presented in the last issue of „Miscellanea Historico-Iuridica”, its author Adam Wójcik did not make sufficient use of the research data available in literature; therefore, the argument he presented requires serious correction and supplementation. This article presents the most important literature on the Message, errors and objections to the text by Adam Wójcik are indicated, and the importance of the Message in the process of Polish-German reconciliation is presented in a synthetic way.
The role of public procurement in the framework of the 2030 Agenda: the approach of institutions and civil society
Authors: Gutiérrez-Goiria Jorge , Amiano-Bonatxea Iratxe
Published: July 2022

Public administration is a key agent for achieving development goals, and this is recognised in the 2030 Agenda and its Sustainable Development Goals. This international consensus requires the involvement of a large number of agents, and the mainstreaming of these global challenges into public policies. However, a practice that could be key in this regard, such as public procurement, does not receive sufficient attention within this framework. Faced with a broad range of goals and targets that cover environmental, economic and social issues, the 2030 Agenda lacks an adequate framework and tools to address the solution to these challenges, and public procurement could have greater prominence as a driver of progress for a number of these goals. The paper studies the role and potential of public procurement as an instrument of policy to contribute to the international development agenda. Therefore, the paper analyses documentation and reports of the main institutions that have worked on these issues to date: United Nations, the Sustainable Development Solutions Network, and the Reflection Group on the 2030 Agenda for Sustainable Development. Despite having been considered in the design of the Agenda, subsequent reports by the United Nations give little importance to the role of public procurement, which contrasts with that expressed by civil society.
The problem of hunger in Spain: analysis of digital media from 2008-2018
Authors: Gracia-Arnaiz Mabel , García-Oliva Montserrat , Demonte Flavia
Published: July 2022

In Spain, between 2008 and 2014, hunger was recognised as a social problem from different spheres. As a relevant actor, the press associated it with the increase in food insecurity as a result of the financial crisis, austerity policies and growing unemployment. This article takes up this previous analysis and compares it with the media discourses produced between 2015 and 2018, a period referred to as "post-crisis". A qualitative study of news stories in three digital newspapers evidences significant changes in the conditions that make hunger an issue of social interest, showing how the perception of what is problematic grows and declines according to the attention received in the media and political sphere. Not only is the amount of news about hunger reduced, but the collective meaning of its causes is re-semanticised. Food insecurity is presented as a health problem resulting from social precariousness and is associated with malnutrition and obesity. We discuss the role of media in the construction of the problem of hunger and food insecurity and we conclude that the socio-economic context and the interaction between social actors are explanatory factors of the discursive transformations identified in press.

La gobernanza energética de la república argentina en el siglo XXI: Desentrañando sus ejes centrales
Authors: Ceppi Natalia
Published: July 2022

For the Social Sciences in general, the notion of governance represents a polysemic and controversial category whose content depends on the used conceptual approach. However, in the field of natural resources, specifically energy, governance is understood as an analytical tool that, by focusing on the decision-making process, makes it possible to examine, through cases, the exercise of State authority, the rules of the game and public-private interactions in the energy sector. This paper analyzes the energy governance process of Argentina during Cristina Fernández (2007-2015) and Mauricio Macri (2015-2019) administrations. Due to their political-ideological differences, ruptures and continuities are traced with a view to addressing the political-economic dimension of energy management as a topic of the public agenda, whose implications are presented both domestically and in foreign policy decisions.
Reseña del libro: The Hacker and the State: Cyber Attacks and the New Normal of Geopolitics de Ben Buchanan
Authors: Brais-Chaves Valery
Published: July 2022

Hackers and their operations have changed geopolitics over the past twenty years and, at the same time, have strengthened their relationship with security. Although these attacks use different infiltration techniques and methods, they all have in common their secret execution which makes it more difficult to detect them. Most of the cases presented by Buchanan in his book "The Hacker and the State Cyber Attacks and the New Normal of Geopolitics"; explain how groups of hackers, mainly from authoritarian States, carry out espionage campaigns, bank fraud, and theft of information to private companies. In this way, the presence of the United States in the network and its continuous investment in the domain of telecommunications are justified. In this new digital sphere, the traditional conception of security is modified. The merely territorial view has been left behind and different needs such as technological protection tools are added into the politics game and analysis.

As cerimónias por ocasião das exéquias dos bispos da Baía (Brasil) deram origem à pregação de dois sermões da autoria de jesuítas na catedral de Salvador – Baía. Neste texto pretendemos estudar os referidos sermões no intuito de avaliar o modo como a parenética era utilizada para disciplinar os fiéis e de que modo se assemelhava a outros textos de teoria política.
Well-posedness and stability for fuzzy fractional differential equations
Authors: Zhang Xuping , Xi Yanli , O’Regan Donal
Published: July 2022

In this article, we consider the existence and uniqueness of solutions for a class of initial value problems of fuzzy Caputo–Katugampola fractional differential equations and the stability of the corresponding fuzzy fractional differential equations. The discussions are based on the hyperbolic function, the Banach fixed point theorem and an inequality property. Two examples are given to illustrate the feasibility of our theoretical results.

Приведено оптичнi характеристики i параметри перенапруженого наносекундного розряду в аргонi мiж електродами з алюмiнiю i халькопiриту (СuInSe2) при p(Ar) = 13,3 і 101 кПа. Внаслiдок мiкровибухiв природних неоднорiдностей на робочих поверхнях електродiв в сильному електричному полi в плазму вносяться як пари алюмiнiю, так I пари халькопiриту, що створює передумови для синтезу за межами розряду тонких плiвок четверного халькопiриту – CuAlInSe2. Дослiджено iмпульси напруги i струму на розрядному промiжку величиною d = 1 · 10−3 м (розмiри наведено в системi СI), а також iмпульсний енергетичний внесок у плазму. Ретельно дослiджено спектри випромiнювання плазми, що дозволило встановити основнi продукти розпаду молекули халькопiриту та енергетичнi стани атомiв i однозарядних iонiв алюмiнiю, мiдi i iндiю, в яких вони утворюються в розрядi. Виявлено репернi спектральнi лiнiї атомiв I iонiв алюмiнiю, мiдi i iндiю, якi можуть бути використанi для контролю за процесом напилення тонких плiвок четверного халькопiриту. Методом числового моделювання параметрiв плазми перенапруженого наносекундного розряду на основi парiв алюмiнiю i халькопiриту, шляхом розв’язку кiнетичного рiвняння Больцмана для функцiї розподiлу електронiв за енергiями розраховано температуру i концентрацiю електронiв у розрядi, питомi втрати потужностi розряду на основнi електроннi процеси i константи швидкостi електронних процесiв в залежностi вiд величини параметра E/N (де E – напруженiсть електричного поля, N – загальна концентрацiя сумiшi парiв алюмiнiю та аргону).

Authors: Kofanov V.A. , Sydorovych K.D.
Published: July 2022

We obtain the strengthened Kolmogorov comparison theorem in asymmetric case.In particular, it gives us the opportunity to obtain the following strengthened Kolmogorov inequality in the asymmetric case:$$\|x^{(k)}_{\pm }\|_{\infty}\le \frac{\|\varphi _{r-k}( \cdot \;;\alpha ,\beta )_\pm \|_{\infty }}{E_0(\varphi _r( \cdot \;;\alpha ,\beta ))^{1-k/r}_{\infty }}|||x|||^{1-k/r}_{\infty}\|\alpha^{-1}x_+^{(r)}+\beta^{-1}x_-^{(r)}\|_\infty^{k/r}$$for functions $x \in L^r_{\infty }(\mathbb{R})$, where$$|||x|||_\infty:=\frac12 \sup_{\alpha ,\beta}\{ |x(\beta)-x(\alpha)|:x'(t)\neq 0 \;\;\forallt\in (\alpha ,\beta) \}$$$k,r \in \mathbb{N}$, $k 0$, $\varphi_r( \cdot \;;\alpha ,\beta )_r$ is the asymmetric perfect spline of Euler of order $r$ and $E_0(x)_\infty $ is the best uniform approximation of the function $x$ by constants.

Published: July 2022

In this paper, we introduce a parametric type of Bernoulli polynomials with higher level and study their characteristic and combinatorial properties. We also give determinant expressions of a parametric type of Bernoulli polynomials with higher level. The results are generalizations of those with level 2 by Masjed-Jamei, Beyki and Koepf and with level 3 by the author.
A educação infantil no contexto da educação brasileira: entre o cuidar, o brincar e o educar
Authors: Linhares Francisco Reginaldo , Costa Maria da Conceição
Published: July 2022

Este artigo, apresenta um recorte teórico da pesquisa “Avaliação da aprendizagem: da organização do trabalho pedagógico ao registro do acompanhamento das crianças no contexto da Educação Infantil”, dissertação de mestrado do programa XXX da Universidade YYY. Com o objetivo de discutir sobre a tríade que envolve o cuidar, o brincar e o educar no contexto da Educação Infantil no Brasil, trata-se de um estudo bibliográfico de abordagem qualitativa que, em sua culminância, apontou a importância das escolas de Educação Infantil trabalharem de forma indissociável a tríade citada, não restringindo-se aos cuidados com a criança, mas se estendendo ao educar e ao brincar, articuladamente. Essa articulação, muito mais do que ação didática, compreende o brincar, o educar e o cuidar como extensos campos de conhecimento que exigem comprometimento docente e políticas públicas que, de fato, reconheçam a infância e suas particularidades como imbrincadas no processo de desenvolvimento educacional de um país.
Occurrence of mycotoxins in pastures: A systematic review
Authors: Aranega João P. R. B. , Oliveira Carlos A. F.
Published: July 2022

In this study, a systematic review is presented on the worldwide occurrence levels of mycotoxins in pastures reported in the scientific literature from January 1987 until December 2021. Trichothecenes and zearalenone were the most frequent mycotoxins found at high levels in pastures from countries in Europe, Oceania, and North America. Alternariol and Ergot alkaloids were also frequently detected, although at low levels. A few surveys were conducted in South American countries, and no information was available from the African and Asian continents, stressing the need for studies on the occurrence of mycotoxins in pastures from those regions, especially in tropical areas, where pastures are used as main sources for animal nutrition.
O racismo na infância e a infância do racismo: vida e rastros de uma criança negra
Authors: Ferreira Emerson Benedito , Abramowicz Anete
Published: July 2022

Resumo Este artigo, com base em uma metodologia arqueogenealógica, teve como objetivo resgatar e cartografar fragmentos de vida de uma criança negra em um documento judicial alocado no Museu Histórico Simonense no ano de 1861 e, sequencialmente, entender esse documento, seus discursos e posições, decifrando como funcionava a maquinaria jurídica em seu mais expressivo conceito de poder-saber e quais olhares e tratativas o poderio local lançava para administrar vidas e corpos. O trabalho procurou entender também como, naquele contexto oitocentista, “cor” e “raça” influenciavam os deslindes processuais. Concluiu-se, com o trabalho, que em meados do século XIX nascia uma nova ideia de criança. Esse modelo de criança, idealizado naquele momento pela medicina higienista, serviria somente à criança branca, católica, de posses. Ele não ampararia a criança negra. Não se tratava somente de um tipo de racismo já existente, mas, sim, de um tipo novo de racismo que nascia junto com a própria ideia de criança. Era a infância desse tipo de racismo no Brasil. E esse racismo teria consequências nos processos judiciais em que figuravam crianças negras. Ele geraria uma justiça seletiva, com decisões judiciais afetadas pela questão racial.
Brincante Body: the travesti presence in the performances of the Reisado quilombos
Authors: Oliveira Junior Ribamar José de
Published: July 2022

ABSTRACT This article analyzes the performance of the Reisado quilombos from the travesti presence in the popular culture of Juazeiro do Norte, Cariri region, in the countryside of Ceará. In order to reflect on the performance and its animated forms, we consider one of the passages from the cartography that flows through sexual and gender dissidences in Ceará’s Reisados, in which we follow the quilombo of the Sagrada Família group between the performance of gender and the animation of the game. Using the route of one of the first travesti Maestras, we point to the encantravar of the brincante body as a way to praise the travesti body, in the spirals of time played.
Supervised Visual Attention for Simultaneous Multimodal Machine Translation
Authors: Haralampieva Veneta , Caglayan Ozan , Specia Lucia
Published: July 2022

There has been a surge in research in multimodal machine translation (MMT), where additional modalities such as images are used to improve translation quality of textual systems. A particular use for such multimodal systems is the task of simultaneous machine translation, where visual context has been shown to complement the partial information provided by the source sentence, especially in the early phases of translation. In this paper, we propose the first Transformer-based simultaneous MMT architecture, which has not been previously explored in simultaneous translation. Additionally, we extend this model with an auxiliary supervision signal that guides the visual attention mechanism using labelled phrase-region alignments. We perform comprehensive experiments on three language directions and conduct thorough quantitative and qualitative analyses using both automatic metrics and manual inspection. Our results show that (i) supervised visual attention consistently improves the translation quality of the simultaneous MMT models, and (ii) fine-tuning the MMT with supervision loss enabled leads to better performance than training the MMT from scratch. Compared to the state-of-the-art, our proposed model achieves improvements of up to 2.3 BLEU and 3.5 METEOR points.

Published: July 2022

Nano-magnesium oxide (MgO) can be used as an expansion agent for cement-based materials, but little is known about the influence of nano-magnesium oxide on the mechanics, microstructure and expansion stability of cement materials. The influence of nano-magnesium oxide on the consistency, fluidity, porosity, dry and wet densities, mechanical properties and microstructures of cement-based materials was researched in this study. The results show that the compressive strength and flexural strength of the cement mortar test block containing nano-magnesium oxide particles increase and are higher than those of the control cement mortar test block at any time. The addition of nano-magnesium oxide increases the mechanical strength of the cement mortar block, and the strengthening effects are most obvious in the early stage of maintenance. When the curing age is 28 days and the nano-magnesium oxide content is 1.5%, the compressive strength and flexural strength of the modified cement mortar test block are the best. Fourier transform infrared spectroscopy and scanning electron microscopy show that the expansion effect of nano-magnesium oxide makes the microstructure of cement-based materials denser and more uniform. This paper also discusses the influence mechanism of nano-magnesium oxide on cement-based materials, which provides a reference for the application of nano-magnesium oxide in cement-based materials.
