Textile fabrics have different heat transfer properties, which depend on the conditions of consumption of the product and various types of processing. All this is of scientific interest for identifying factors and features of individual materials. The purpose of the study was to track heat transfer through packages of multilayer textile materials in stationary and transient thermal conditions. A particular property of textile materials lies in their ability to deform under their weight so that a sample can be placed between meshes of a material with high heat resistance. Heat transfer is carried out by convective heat transfer between the surface of the material and the air. To conduct this study, the Fourier law was used in the calculations and numerical methods for solving heat conduction problems. The developed program, which was created for the study, permit to write parameters to a computer and uses them to calculate the thermophysical properties of the sample. As a result of the work, graphs of the state of the package of materials were presented, and a device was proposed that allows to determine the modes that characterize the thermophysical properties of the materials used in the manufacture of clothing and its packages. The device admits with high accuracy to record, record and store changes in the parameters at which studies were conducted.

Published: August 2021

The issue of magnesia corrosion of grouting materials in oil and gas wells is very relevant in the construction of oil and gas wells since magnesia salts can lead to the destruction of Portland cement-based cement stone within few months. When fastening powerful intervals of salt deposits represented by magnesium salts, the use of magnesia cements is effective. However, individual layers and interlayers containing dissolved magnesium salts are not individually cemented, but overlap over the entire interval of the open hole with cement Portland cement, which can be destroyed due to magnesia corrosion. The main aim of the paper is to analyze the corrosion of Portland cement stone in aggressive environments of magnesia. As the quantitative indicators characterizing the degree of stone damage, the thickness of the damaged layer and the stone resistance coefficient are taken, characterized by the ratio of the compressive strength or bending strength of stone samples after being in an aggressive environment to the strength of control samples at the same hardening time. The corrosion resistance of cement stone was assessed after 8 weeks in an aggressive magnesia environment. Also, the role of MgCl2 concentration on the mechanism of corrosion damage to cement stone was studied. The use of reducing the water-cement ratio and adding palygorskite clay to reduce the porosity of cement stone and reduce the rate of corrosion damage is proposed. The kinetics and the main factors affecting the corrosion process were considered, an X-ray diffraction analysis of corrosion products and unaffected cement stone was carried out.

The formation of an urban ecological environment is a local trend of the current time. It is necessary to solve the problems of city landscaping since, at the present stage, the deterioration of the state of green spaces and a decrease in the area that they occupy are observed. The article presents data on the state of tree vegetation in the largest park in Vologda (Vologda Region, Russia). According to the dendrometric assessment results in Mira Park, the number of drawback types in each tree species at a specific diameter of the trunk was revealed. It is worth noting that the most common types of drawbacks in linden trees in Mira Park are mechanical damage and frost cleft. The investigation was carried out based on the “Inventory Survey Procedure for Urban Plantations.” Most often, wood drawbacks in this species occur on the trunk diameters in the range from 40 to 52 cm. Based on the bioecological assessment performed in Mira Park, it can be stated that the highest percentage of good tree health status was found in pine – 67.3%, the highest percentage of satisfactory tree health status was found in elm – 35.7% and the highest percentage of poor tree health status was found in oak – 16.1%. According to the results of the investigation, it can be said that most of the tree plants are in good and satisfactory condition. The highest percentage of poor health status was found in tree species such as oak and poplar. There are such common flaws on tree plantations as mechanical damage, a frozen slot, and a curved trunk. The current situation in the biggest park in the city of Vologda is stable. However, to improve the systematic condition, it is necessary to hold some activities that should preserve and diversify the tree and shrub plantations, as well as help to solve existing problems.

Современная система образования Германии переживает большие изменения. Одним из них является введение во всех типах немецких школ (от начальной до гимназии) нового учебного предмета «немецкий как второй язык». Это обусловлено миграционными процессами, происходящими в немецком обществе. Авторами рассматриваются педагогические и методические основы обучения немецкому как второму языку, а также проводится терминологическое отграничение понятия «немецкий как иностранный язык» и «немецкий как второй язык». Кроме того, авторы обращаются к характеристике таких терминов как «двуязычие» и «билингвизм». В центре внимания авторов актуальная ситуация в школах Германии в связи с обучением немецкому как второму языку. В результате педагогического наблюдения выделяются основные сложности преподавания немецкого как второго языка и обнаруживаются недостатки в системе и качестве обучения немецкому языку как второму. Анализируются причины возникающих сложностей и возможные пути их устранения. Авторы демонстрируют сложившуюся систему обучения на примере двух типов немецких школ – общеобразовательной школы и гимназии – для более объективного анализа. Впервые была подробно рассмотрена система обучения немецкому языку как второму в отличие от традиционной системы преподавания немецкого языка как иностранного.

Published: August 2021

Lae city is the capital of the Morobe Province in Papua New Guinea. It is the main land transport corridor, the country's main industrial hub and largest cargo port. As a result of the urbanization and industrialization process, more people had migrated to Lae city for better opportunities.
These activities contributed to the generation of a considerable amount of solid waste that has become a real concern. The present research aims to understand the existing practices of Solid Waste Management, to estimate per capita waste generation rate and composition of waste, to identify
the issues and challenges faced in this regard and suggest methods for improvement. All wastes from the city are discarded at the Second Seventh Landfill (SSL) open dump site, located about 10 to 12 kilometers drive away from the city, causing enormous pollution to the surrounding environment.
The per capita waste generation rate witnessed was 0.312 kg per capita per day with a composition of 66% organic waste, 22% recyclable, and 12% non-recyclable materials. It was found that ineffective legislation, lack of law enforcement were the challenges faced by the Lae city council. Rehabilitation
of SSL or the construction of a new sanitary land fill should be recommended for effective management.

Finland's health care system has evolved over the years, with its distinctive features being tax funding, the provision of the vast majority of medicines and medical services by public and municipal authorities. to study the experience of EU countries in the field of health care in the organization of circulation and availability of medicines. To achieve this goal used the methods of regulatory, documentary, comparative and graphical analysis. The increase in the cost of medical care leads to the fact that the state is increasingly thinking about containing costs. The level of co-financing by patients is growing, at the same time measures are being taken to limit the selling price of medicines. The existing system of reference prices promotes the entry of generics into the market and, apparently, this direction will develop. A characteristic feature of the health care and pharmaceutical supply system in the Nordic countries is coordination, which is implemented at different levels and in many forms. The organization of the circulation and accessibility of medicines for the population in Finland is based on covering the costs of medicines through the social insurance system, but with the participation of the state. The priority common aspects of the functioning of the national health care systems of the Scandinavian region remain: coordination between hospitals and definition of their areas of activity; coordination between general services and specialized assistance centers; coordination of the organization of drug circulation and medical care for certain categories of patients (privileged categories, patients with oncological diseases, etc.); coordination of pharmaceutical support and medical services for patients with chronic diseases (diabetes, etc.); coordination of long-term pharmaceutical provision and medical care for the elderly.

Marine stocking in Chile: a review of past progress and future opportunities for enhancing marine artisanal fisheries
Authors: Cárcamo P Francisco , Henríquez-Antipa Luis A , Galleguillos Francisco , Figueroa-Fábrega Luis D
Published: August 2021

Chile has a long history of restocking, stock enhancement, and translocation to support artisanal or small-scale fisheries; however, these programs have been scarcely discussed in the scientific literature. Here, we present a review of previous initiatives and discuss specific areas
for future progress. We identified 204 releases across 117 different areas, involving 7 taxonomic groups and 22 species (20 marine and 2 freshwater). Marine stocking mainly occurred within the context of the spatial framework through which artisanal fisheries are managed [Management and Exploitation
Areas for Benthic Resources (MEABR)], and over 60% involved translocation of wild individuals rather than release of hatchery-reared seed. While "stock enhancement" was the primary intention for most releases, it is unclear whether depleted spawning biomass or other recruitment limitations
were the primary motivation, and few projects reported more than one stocking event. The echinoid Loxechinus albus and the gastropod Concholepas concholepas were the main target species. Only 6% of projects examined reported positive results that could be linked to releases,
and none reported the use of tagging or analysis of costs or benefits. There are several areas for targeted development that should improve the social and economic outcomes from marine stocking activities. This synthesis provides a snapshot of marine stocking in Chile to date and highlights
opportunities that are relevant to both Chile and other nations with substantial small-scale fisheries.

Nova-Bollinger Ni-Cu Sulfide Ore Deposits, Fraser Zone, Western Australia: Petrogenesis of the Host Intrusions
Authors: Taranovic Valentina , Barnes Stephen J. , Beresford Steve , Williams Morgan , MacRae Colin , Schoneveld Louise E.
Published: August 2021

The Nova-Bollinger Ni-Cu sulfide ore deposit is the first economic Ni-Cu-Co sulfide deposit to have been discovered in the Albany-Fraser orogen in Western Australia. The host rocks are mafic-ultramafic intrusive cumulates subdivided into two connected intrusions, designated Upper and Lower. The Upper Intrusion is bowl-shaped and modally layered with alternating peridotite and norite mesocumulate layers, with a Basal Series of dominantly orthocumulate mafic lithologies. The Lower Intrusion is a much thinner, semiconformable chonolith (flattened tube-shaped intrusion) consisting of mostly unlayered mafic to ultramafic orthocumulates. The Lower Intrusion hosts all the high-grade mineralization and most of the disseminated ores. A distinctive plagioclase-bearing lherzolite containing both orthopyroxene and olivine as cumulus phases is a characteristic of the Lower Intrusion and the Basal Series of the Upper. The intrusions differ slightly in olivine and spinel chemistry, the differences being largely attributable to the more orthocumulate character of the Lower Intrusion. Sector zoning in Cr content of pyroxenes is observed in the Lower Intrusion and in the lower marginal zone of the Upper and is attributed to crystallization under supercooled conditions. Symplectite pyroxene-spinel-amphibole coronas at olivine-plagioclase contacts are ubiquitous and are attributed to near-solidus peritectic reaction between olivine, plagioclase, and liquid during and after high-pressure emplacement, consistent with high Al contents in igneous pyroxenes and estimates of the peak regional metamorphism. Original cumulus olivines had compositions around Fo86 and were variably Ni depleted, interpreted as the result of preintrusion equilibration with sulfide liquid. The Upper and Lower Intrusion rocks represent cumulates from a similar parental magma, a high-Al tholeiite with MgO between 10 and 12%, low TiO2 (0.5–0.6%), and high Al2O3 (14–17%). Modeling using alphaMELTS indicates a primary water content of around 2 wt %. The cumulates of both intrusions were derived via multiple magma pulses of liquid-olivine-sulfide slurries with variable amounts of orthopyroxene emplaced into the deep crust at pressures of around 0.7 GPa during the peak of regional metamorphism. The intrusions developed initially as a bifurcating sill, the lower arm developing into the ore-bearing Lower Intrusion chonolith and the upper arm inflating into the cyclically layered Upper Intrusion.

The conclusions of this dissertation are: Verbal intelligence from the perspective of the Koran carries a transcendental transformative informative theory. This is based on the qaul (verbal) expression which is informative which means ensuring the meaning of the message reaches the communicant, with several types of expressions, such as: 1. Qaul Maisûr/phrases that are easy to understand, 2. Qaul Baligh/phrases whose message is conveyed, and; 3. Qaul Ma'ruf /expressions with attention to local culture. As for Qaul which is transformative, which means speech that is able to change the communicant to the understanding and application of Islamic teachings which is better used by the Koran with the words: 1. Qaul Sadîd /words/words that are on target, 2. Qaul Ahsan/speech or the best words, 3. Qaul Tsâbit/strong and lasting speech, 4. Qaul Layyin/uangkap who is gentle, 5. Qaul Thayyib/good expressions or speech (diction is not dirty), and; 6. Qaul Salâm/expressions or sayings that are full of peace. Qaul that is transcendental is Qaul al-Haqq/haqq speech (based on Islamic texts), namely: 1. Qaul Fashl /words from wise thoughts to reveal what is haqq and what is falsehood, 2.

This dissertation also reveals that the purpose of transformation in verbal communication can be realized if there is an interrelation between communicators (Surat ar-Rahman/55: 4), methods (Surat an-Nahl/16: 125), material (Surat al-Isra '/17: 36) and the communicants (Surat an-Nisa '/4: 164).The theory of verbal intelligence from the perspective of the Koran is an interrelation theory that combines the informative theory introduced by Claude Shannon (1948) and the transformative theory introduced by (Jack Mezirow (1978), "transformative learning refers to the process in which a person changes the accepted framework. able to change emotionally, and reflectively so that it can generate confidence in thinking and implemented in the form of action.

Verbal intelligence with transcendental transformative informative theory in this dissertation is different from the opinion of Henry H. Calero (2005) who is more concerned with actions than words, as well as with Howard Gardner.

This dissertation uses a qualitative method, while the method of interpretation used in this dissertation is the thematic interpretation method (maudhu'i). This method was chosen because it can reveal the perspective of the Koran regarding verbal intelligence that is adaptive to contemporary communication needs
Pandemia como laboratório de poder
Authors: Alves Marco Antônio Sousa
Published: August 2021

Crises sanitárias constituem momentos propícios para a experimentação de novas tecnologias de poder. Nesses contextos, velhas práticas de governo são colocadas em suspenso e, em caráter inicialmente emergencial e excepcional, novas táticas de controle e organização social são ensaiadas. O estudo desenvolvido neste artigo toma por base a análise empreendida por Foucault ao longo dos anos 1970, que distinguiu três ensaios nesse sentido, quais sejam, o modelo da lepra, da peste e da varíola, que estão associados a diferentes mecanismos de poder, de tipo soberano-legal, disciplinar e biopolítico ou securitário, respectivamente. Após uma apresentação da contribuição foucaultiana, o artigo procura traçar uma linha de atualização, dando prosseguimento ao projeto de uma analítica do poder. O foco é então direcionando para o novo modelo da COVID-19 que emerge no presente, marcado pela datificação da vida, pelo uso de big data, pela vigilância ubíqua e pelo governo algorítmico, no seio de um grande sonho tecnocrático, de uma sociedade digitalizada, controlada e gerida eficientemente.

Authors: Acioly Dimitri Alexandre
Published: August 2021

O presente artigo tem caráter teórico-crítico e ensaístico, situando-se interdisciplinarmente no âmbito da filosofia, mais precisamente no espaço da ética e política, e teoria dos direitos humanos. Através de pesquisa bibliográfica qualitativa, com inserção de elementos literários, o estudo investiga a relação que a sociedade trava com a pessoa que se encontra privada de liberdade cumprindo pena. Abordando o tema a partir de três eixos diferentes, a dimensão animal, a dimensão alien e dimensão humana, verifica-se que a cidadania do preso foi eclipsada pelo encarceramento em massa e pela sua desumanização. Por isso, objetiva-se intervir contra o imaginário social do encarcerado como simples elemento de perigo, ressaltando-lhe a humanidade, cidadania e circunstância de pessoa imersa no trânsito da duração. O trabalho se funda principalmente em elementos da ética de Emmanuel Levinas, com importantes contribuições de Bergson, Judith Butler, Rafael Godoi, Carl Schmitt, Bethânia Assy e Achille Mbembe, além de metáforas de Antoine de Saint-Exupéry.

Procedural justice in the criminal justice chain

It has been proposed that when people perceive their treatment by criminal justice actors as more procedurally just, they will be more likely to comply with the law. Existing research mainly focused on the police or the judge. This longitudinal study examined how prisoners experienced their treatment by five different criminal justice actors using data from the Prison Project. The prisoners were most positive about the procedurally fair treatment by their lawyer and least positive about the treatment by the police. Additionally, the perceived treatment by the police was associated with the treatment by other actors at subsequent moments.
A realização de atividades acadêmicas no ensino superior em tempos de pandemia: até que ponto é possível?
Authors: Silva Givanildo Da , Filho José Diogenes Dos Santos , Silva Matheus Vieira da
Published: August 2021

A presente pesquisa teve como objetivo perceber a situação dos estudantes do curso de Pedagogia, da Universidade Federal de Alagoas, campus A. C. Simões, em relação às possibilidades de desenvolvimento das atividades acadêmicas. A metodologia da pesquisa esteve pautada em uma perspectiva qualitativa, tendo como técnica o estudo de caso e o questionário como coleta de dados. A partir dos resultados, foi possível analisar a complexidade para a realização de atividades acadêmicas pelos participantes, visto que muitos estão inseridos em uma realidade cuja pobreza estrutural, a exclusão social e a desigualdade econômica são intensas, tendo que enfrentar múltiplos desafios, o que os impede de desenvolver as atividades acadêmicas em tempos de pandemia e de isolamento social.
Minorías étnicas, desigualdad y educación en tiempos de pandemia
Authors: Pérez Mora Ricardo

El presente artículo se dirige a analizar algunas condiciones de desigualdad  estudiantes indígenas en el marco de la pandemia ocasionada por el COVID-19 en una universidad pública estatal en México. Se presenta algunos datos del contexto para problematizar sobre dichas desigualdades. A partir de ello se contruyen 3 categorías analíticas para conocer las condiciones de los estudiantes: condiciones generales, condiciones de acceso y condiciones subjetivas. Los datos se obtuvieron a través de un cuestionario que respondieron 104,141 estudiantes de los cuales 968 se autodefinieron como pertenecientes a un pueblo indígena. El estudio muestra las profundas desigualdades que afectan a las minorías étnicas que se intertan como estudiantes a la educación superior, desigualdades que se agravaron en el periodo de la pandemia.

Autotuning LLVM OptimizationPasses for Matrix Multiplication in Rust
Authors: de Sousa Emanuel Lima , Bruel Pedro , Goldman Alfredo
Published: August 2021

The LLVM compiler framework transforms its Intermediate Representation (IR) to optimize code. These transformations are controlled by flags which interfere on metrics such as the execution time. Selecting flags to improve the execution time of a program is difficult, and requires expert knowledge. Autotuning methods can automate parts of this process and help understanding the underlying search spaces. This paper describes ongoing work, showing that LLVM flags can impact the execution time of a Rust matrix multiplication algorithm, and planning future autotuning experiments for flag selection.
Aceleração de métodos de empilhamento de dados sísmicos na nuvem com CUDA, OpenCL e SPITS
Authors: Pinton Gustavo Ciotto , Borin Edson
Published: August 2021

Técnicas de imageamento do subsolo marítimo vêm sendo fundamentais para diversas aplicações da indústria, notadamente para a exploração de petróleo e gás. Neste artigo, nós avaliamos uma implementação para a procura de parâmetros do meio marítimo maximizando a medida de coerência para três diferentes modelos de tempo de trânsito 2D (incluindo o modelo OCT) que automaticamente realiza a distribuição de tarefas idempotentes e independentes a nós de uma nuvem computacional com suporte às plataformas CUDA e OpenCL. Além disso, para evitar degredação de desempenho devido a fenômenos como a transferência de dados e \emph{cache misses}, nós introduzimos uma heurística para a seleção da fração dos dados que deve ser de fato considerada.
Aplicação de Algoritmos Combinatórios para o Problema do Caminho Tropical em Grafos
Authors: Sampaio Igor de M. , Lima Karla R. P. S.
Published: August 2021

O problema do caminho tropical em grafos, TPP, consiste em, dado um grafo G e uma coloração dos vértices de G, encontrar um caminho colorido P em G em que cada cor usada por G apareça exatamente uma vez em P. Neste projeto propomos investigar duas versões de otimização desse problema: STPP, o problema do caminho tropical mínimo, que consiste em encontrar um caminho tropical de peso mínimo em que os pesos são atribuídos às arestas de G, e o MTPP, o problema do caminho tropical máximo, que consiste em encontrar o caminho com o maior número de cores usadas por G. É sabido que o problema é NP-difícil para grafos em geral e algumas outras variantes do problema. Do ponto de vista da combinatória poliédrica existem inúmeras técnicas de modelagem que permitem encontrar soluções ótimas para problemas dessa natureza em termos da complexidade computacional. Diante disso, o objetivo desse projeto é implementar uma boa formulação para o problema e associar algoritmos de alto desempenho para obtenção de soluções ótimas para instâncias de grande porte.
Arbeitsvermittlung zwischen Nachhaltigkeit und Abbildbarkeit. Wie Vermittlungsfachkräfte Entscheidungsspielräume nutzen
Authors: Freier Carolin , Senghaas Monika
Published: August 2021

Dieser Artikel untersucht, wie Beschäftigte in Agenturen für Arbeit zusätzliche Entscheidungsspielräume in der Arbeitsvermittlung nutzen und dabei Arbeitsmarkt- und Sozialpolitik als Street-Level Bureaucrats umsetzen. Anhand der Analyse qualitativer Interviews und Gruppendiskussionen mit Vermittlungsfachkräften rekonstruieren wir, dass Vermittlungsfachkräfte ihre Entscheidungsspielräume einsetzen, um Individualität und Vertrauen in der Beziehung mit Arbeitsuchenden zu befördern. Wir argumentieren, dass die Nutzung der Entscheidungsspielräume nicht allein von Ambiguitäten politischer oder organisationaler Vorgaben geprägt ist: Sich wandelnde Organisationsziele, die Erweiterung von Entscheidungsspielräumen der Vermittlungsfachkräfte sowie die Situation am Arbeitsmarkt, so unsere Schlussfolgerung, befördern eine Ausrichtung auf eine nachhaltige Arbeitsvermittlung.
„...und plötzlich sitze ich auf dem Spielteppich und langweile mich zu Tode“. Eine Soziologie der Langeweile am Beispiel Mutterschaft
Authors: Ohlmeier Silke , Czarny Moritz , Pfaff Holger
Published: August 2021

Dieser Artikel widmet sich dem Phänomen mütterlicher Langeweile in der Elternzeit. Entlang einer qualitativen Analyse eines Online-Elternforums wird gezeigt, wie gesellschaftliche Diskurse und normative Vorstellungen in Form latenter Sinnstrukturen mütterliche Langeweile in der Elternzeit beeinflussen. Das Ergebnis der Analyse ist, dass sich das Phänomen aus drei miteinander verbundenen Strukturmerkmalen konstituiert: (1.) aus einer verinnerlichten Idealvorstellung vermeintlich komplett erfüllender Mutterschaft, die konträr zum eigenen Erleben steht, (2.) aus einer gleichzeitig ubiquitär verinnerlichten Erwerbszentrierung und Abwertung von ‚Familienarbeit‘ und (3.) aus einer gescheiterten Bewältigungsstrategie, die auf Beschäftigung anstatt auf Reflexion normativer Vorstellungen abzielt und langfristig ein Ausharren in der Langeweile hervorbringt. Ziel des Artikels ist es, einen Beitrag zur Enttabuisierung von Langeweile und Mutterschaft zu leisten und dadurch das Potenzial einer Soziologie der Langeweile hervorzuheben.
Ad usum scholarum
Authors: Holzberg Niklas
Published: August 2021

Niklas Holzberg, a professor of Classics at the University of Munich until his retirement in 2011, offers a collection of lectures he held over a period of eleven years (2008–2019) in various parts of Germany, both at schools where Latin is taught and as part of advanced training programmes for those that teach it. His interpretations of the Latin texts in question, which are all required reading at grammar school level, focus on the classroom, that is, on the practicalities of learning and teaching. The Augustan poets Virgil, Horace and Ovid take up a large part of this volume, but still leave room for other genres that are introduced and illustrated using prominent exponents of each: Catullus and Martial (epigram); Pliny the Younger (epistle); Caesar, Sallust, Livy and Tacitus (history); and Petronius (novel). The principal intention of these papers, all of which draw on the most recent research into Latin literature, is to provide new impetus to reading material in the subject of Latin in schools.
