Published: April 2022

Weight is of great importance in the aircraft industry. Aircraft are made of aluminum alloys that are susceptible to heat treatment, because they are light in weight and are metal strong enough for the dynamic designed loads they can face, but there are other reasons for obtaining alternative materials, and these materials are composite materials that it is lighter in weight than aircraft made of aluminum, firstly, and secondly, it can be formed into attractive shapes, eliminating welding and rivets, and thirdly, it can be formed into aerodynamic shapes. This work is based on designing a three-dimensional model consisting of aluminum alloy (AA-6061-T6) of the structure helicopter and then comparing it with five other models of different metal and composite materials to obtain a structure that has the least weight among these models. The results indicate that the best model with the lowest weight is the fourth model consisting of carbon fiber, proportions and weight of a square meter and a thickness of (28 mm) than the weight of the first model consisting of aluminum and weighing (81 kg), it was less than (22.7%). Then the fifth model, which consisted of an outer layer of aluminum with a thickness of five millimeters and another inner layer of aluminum of the same thickness, and between the inner and outer layer eighteen layers of carbon fiber, where the percentage of decrease in it compared to the first model by up to (19.2%), and worse a model in terms of weight is the second model was made of steel, which has a weight that is almost twice the weight of the first model.

Published: April 2022

An increasing demand for energy and climate change encouraged the search for new ways of using renewable energy sources, including in building structures. At present, improving energy efficiency in buildings by integrating thermal energy storage materials is an urgent task. This paper proposes a mathematical model for the thermal regime in a building with a TES building envelope. The enclosure model consists of gypsum board with 25% of phase change material (PCM). The PCM layers of different thickness reduce room temperature and heat load. The effectiveness evaluation of the proposed model involved calculating the thermal conductivity using the finite difference method. The results show that the incorporation of thermal energy storage materials can reduce temperature fluctuations in the room and maintain a comfortable temperature for a long time (up to 8 hours). With an increase in the thickness of the thermal energy storage layer, the cooling time of the exterior surface of the internal wall also increases.

Cloud computing has grown into a critical technology by enabling ground-breaking capabilities for Internet-dependent computer platforms and software applications. As cloud computing systems continue to expand and develop, the need for a more guaranteed, reliant service, and an early task execution status from Cloud Service Providers (CSP) is vital. Additionally, efficient prediction of task failure significantly improves the running time as well as resource utilization in cloud computing. Task failure forecasting in the cloud is regarded as a challenging task based on the literature review conducted in this study. To address these issues, the goal of this study aimed to create fast machine learning approaches for reliably predicting task failure in cloud computing and analyzing their performance using multiple assessment criteria. The Google cluster dataset was used in this study, coupled with Artificial Neural Network (ANN), Support Vector Machine (SVM), and a stacking ensemble method, to forecast job failure in a cloud computing context. The results show that the proposed models can predict the failed tasks both effectively and efficiently. The stacking ensemble outperformed the experimented models, reaching a 99.8%. The suggested paradigm could greatly benefit cloud service providers by decreasing wasted resources and costs associated with task failures.

Authors: Wernke Rodney
Published: April 2022

O estudo objetivou mensurar o efeito dos prazos do ciclo financeiro na lucratividade das operações de revenda de milho de um frigorífico para os seus fornecedores de suínos. Para esta finalidade foi utilizada metodologia qualitativa, descritiva e no formato de estudo de caso. Foram apresentadas as principais características do contexto estudado e evidenciada a diferença entre o resultado da venda “com” e “sem” a consideração dos prazos do ciclo financeiro na situação inicial, bem como numa simulação de aumento de cinco dias no prazo médio de pagamento dos fornecedores de milho. No primeiro cenário constatou-se que há uma redução média de 24,85% no resultado do período se comparados a margem de contribuição e o resultado considerando os prazos do ciclo financeiro. Tal situação poderia ser amenizada com a obtenção de mais cinco dias para quitar as compras de milho, pois se mantidos os demais dados e conseguido o aumento de prazo, o resultado final seria 20,34% menor que a margem de contribuição original. As contribuições desta pesquisa consistem em (i) evidenciar como avaliar a influência da extensão do ciclo financeiro no resultado das vendas da comercialização de milho pelo frigorífico e (ii) disponibilizar um instrumento de avaliação (planilha) a respeito, que pode ser atualizado periodicamente.
La constitucionalización del derecho internacional de los derechos humanos y la secularización en América Latina
Authors: Góngora Mera Manuel
Published: April 2022

En este artículo se sostiene como argumento central que el movimiento constitucionalista de derechos humanos y el derecho internacional de los derechos humanos (DIDH) han jugado un papel crucial en el proceso de secularización en América Latina. Su objetivo es analizar cómo la región ha mantenido en su proceso de secularización una trayectoria significativamente convergente respecto a sus estándares normativos en materia religiosa y cómo, sobre la base de esa experiencia histórica regional, se ha desarrollado un constitucionalismo transformador en la ponderación judicial de casos conflictivos entre libertades religiosas y otros derechos humanos. Pese a las particularidades nacionales y a los diferentes niveles de implementación del DIDH a nivel interno, la constitucionalización del DIDH en varios países latinoamericanos ha producido un significativo acercamiento basado en estándares internacionales mínimos. Ello es especialmente destacable porque esta convergencia de reglas se ha producido en un contexto internacional adverso, dominado por tendencias autoritarias ultraconservadoras y nacionalistas que han generado retrocesos evidenciados en la intensificación del odio y la intolerancia religiosa. Considerando esta trayectoria tan disímil frente al resto del mundo, el artículo sugiere que América Latina sea analizada teóricamente desde sus especificidades, para lo cual se propone la aplicación de un enfoque de secularidades entrelazadas.
El concepto de familia en la jurisprudencia de la Corte Constitucional colombiana y su incidencia en las políticas públicas: una lectura en clave hermenéutica
Authors: Ordóñez Torres Nayda , Sterling Casas Juan Pablo
Published: April 2022

Este texto pretende analizar el rediseño del concepto de familia desde la jurisprudencia de la Corte Constitucional, a partir de la Constitución Política de 1991, y su impacto en las políticas públicas en esta materia. Lo anterior en un escenario que supone la pluralidad étnica y cultural reconocida en el texto constitucional que ha generado retos respecto de varias instituciones (entre ellas la familia), así como propiciado un debate entre las posiciones tradicionales y nuevas visiones que pretenden la superación conceptual y práctica de aquellas. Este nuevo escenario generó un fuerte rechazo por parte de la población, que, con una postura conservadora forjada sobre la base de la hegemonía de la Iglesia Católica y sus tradiciones, se resiste a concebir el fenómeno familiar por fuera de estructuras e interpretaciones rígidas. Dicho contexto condujo a que los jueces, en especial la Corte Constitucional, se vieran convertidos en actores de las políticas públicas tendientes a rediseñar el concepto de familia, lo que resulta novedoso en tanto los enfoques clásicos de las políticas públicas no suelen considerar como actores a los jueces, lo que hace necesario abordar el fenómeno desde un enfoque neoinstitucional de estas.

Znaczenie ludobójstwa i terroru w turystyce poznawczej
Authors: Tanaś Sławoj
Published: April 2022

Autor zwraca uwagę na wpływ aktów terroru i zbrodni wojennych na regresję i rozwój turystyki. Ataki terrorystyczne, ofiarami których są turyści, oraz zbrodnie wobec ludności cywilnej ograniczają lub całkowicie hamują rozwój turystyki. Terroryzm jest więc barierą rozwoju gospodarki turystycznej. Z czasem jednak pamięć o zbrodni i jej ofiarach, w wyniku podjętych działań dokumentujących i upamiętniających, może stać się impulsem do organizowania przestrzeni, które będą odwiedzane w ramach podróży turystycznych lub krajoznawczych.

Актуальность. Вибрации бурового снаряда любого происхождения, возникающие в процессе бурения скважины, приводят к снижению качества проводимых работ. Известные методы борьбы с данным явлением осложнены технически и технологически. При бурении породоразрушающим инструментом типа PDC одной из причин возникновения поперечных колебаний бурового инсрумента является низкий уровень сил трения рабочей грани резцов о горную породу. Современные возможности синтеза алмазного материала позволяют изготавливать PDC различной формы и размеров. Разработки в области создания конструкции резца PDC с вогнутой рабочей поверхностью способствуют развитию методов профилактики поперечных колебаний резца и как следствие снижению уровня вибрации всей бурильной колонны. Цель: разработка конструкции породоразрушающего инструмента типа PDC, способствующей гашению вибраций бурового снаряда. Объект: особенности процесса взаимодействия горной породы с резцом PDC, обладающим вогнутой формой рабочей поверхности. Методы: метод имитационного компьютерного моделирования, метод научного познания, аналитические исследования, анализ. Результаты. Возникающие на вогнутой поверхности резца PDC усилия направлены на встречу друг другу и, противодействуя, предотвращают поперечное смещение бурового инструмента. Оптимальный угол вогнутости рабочей поверхности резца должен находиться в пределах от 104 до 155 градусов, именно такой интервал значений угла способствует созданию оптимальных условий производительности долота с сохранением антивибрационного эффекта. Конструкция резца PDC с вогнутой режущей поверхностью в виде конуса или сферы позволяет не только снижать вибрации инструмента, но и способствует очищению забоя и созданию зоны предразрушения горной породы перед резцом за счет энергии струи промывочной жидкости, что повышает эффективность разрушения горной породы.

Актуальность. Хозяйственная деятельность на заболоченных территориях Западной Сибири в условиях изменения климата требует научного обоснования методики экологического мониторинга и природоохранных мероприятий. Один из эффективных способов такого обоснования с учетом дефицита наблюдений – математическое моделирование гидрогеодинамических и гидрогеохимических процессов в болотных экосистемах. Цель: выявление механизмов природно-техногенного распределения концентраций Cl– в водных вытяжках из торфов по глубине торфяной залежи. Методы: полевой эксперимент, методы определения химического состава болотных вод и водных вытяжек из торфов и минеральных отложений, методы математического моделирования. Результаты и выводы. Проведен эксперимент по изучению самоочищения евтрофного Обского болота на юге Томской области (выпуск на поверхность болота 50 л раствора NaCl с концентрацией 20 г/дм3) и установлен характер изменения концентраций Cl– в торфяной залежи до и после выпуска раствора. Для объяснения выявленных фактов выполнены разработка и апробация математических моделей водного и геохимического режима участка торфяного болота. В результате показано, что: 1) болотные воды образуют общий поток с подземными водами в сторону реки Оби; на границе болота возможны периодические колебания напора подземных вод; 2) в нижней части торфяной залежи на исследуемом участке сформировался локальный водоупор, препятствующий распространению веществ по торфяной залежи; 3) распределение индикатора (Cl–) по торфяной залежи в значительной мере зависит не только от первоначальных объема и концентрации NaCl и наличия водоупора, но и от характера увлажнения болота. Даны рекомендации по использованию результатов моделирования.

Campylobacter jejuni Pericarditis: A Case Report
Authors: Neves-Maia Joao , Gomes Catarina , Marinho António , Alves Rute
Published: April 2022

Campylobacter jejuni is one of the most common causes of enteritis. In rare cases, extraintestinal infection can occur, with a handful of cases of cardiac involvement, of which the pathophysiological mechanism is unclear. We report a case of pericarditis in a patient with X-linked agammaglobulinemia presenting with chronic diarrhea and chest pain who evolved to cardiac tamponade, requiring a pericardial window and a long course of broad-spectrum antibiotics. To the best of our knowledge, this is the third case of pericarditis caused by Campylobacter jejuni reported in the literature, the second in a patient with X-linked agammaglobulinemia. Despite its rarity, this case serves as a reminder of Campylobacter as a potential cause of cardiac inflammation for clinicians treating pericarditis/myocarditis, especially in patients with a history of diarrhea or immunosuppression.
(Poly)phenolic compounds and gut microbiome: new opportunities for personalized nutrition
Authors: Narduzzi Luca , Agulló Vicente , Favari Claudia , Tosi Nicole , Mignogna Cristiana , Crozier Alan , Del Rio Daniele , Mena Pedro
Published: April 2022

For decades, (poly)phenols have been linked to cardiometabolic health, but population heterogeneity limits their apparent efficacy and the development of tailored, practical protocols in dietary interventions. This heterogeneity is likely determined by the existence of different metabotypes, sub-populations of individuals metabolizing some classes of (poly)phenols differently. The gut microbiota plays a major role in this process. The impact of microbiota-related phenolic metabotypes on cardiometabolic health is becoming evident, although the picture is still incomplete, and data are absent for some classes of (poly)phenols. The lack of a complete understanding of the main microbial actors involved in the process complicates the picture. Elucidation of the mechanisms behind phenolic metabotypes requires novel experimental designs that can dissect the inter-individual variability. This paper, in addition to providing an overview on the current state-of-the-art, proposes wider metabotyping approaches as a means of paving the way towards effective personalized nutrition with dietary (poly)phenols.

International Experience in the Design of China's Carbon Tax System
Authors: Zhang Xinyi
Published: April 2022

Since the beginning of the 21st century, developing a low-carbon economy and reducing greenhouse gas emissions have become the consensus of the international community. The modern tax system is a green tax system. In theory, levying a carbon tax has the intrinsic value of internalizing the external cost of carbon emissions, releasing the double dividend of environmental taxation, and supplying internal value of global public goods for addressing climate change. It is of strategic significance to achieve peak carbon dioxide emissions and carbon neutrality, promote high-quality development, build an ecological civilization, ensure the sustainable development of the Chinese nation, and build a community with a shared future for mankind. Some western developed countries have established relatively complete carbon tax systems and accumulated many useful experiences in this regard. Based on the various practices of carbon tax collection in foreign countries, this paper proposes system design suggestions for the introduction of carbon tax in our country from four aspects: tax model, tax scope, tax rate and tax preference, and revenue-neutral recycling.

Authors: Menezes Jean Michel dos Santos , Pereira Bárbara Samanta Almeida
Published: April 2022

O livro didático é um dos principais recursos didáticos utilizados pelos professores da Educação Básica. Esse instrumento apresenta papel fundamental na escolha e evidência dos conteúdos a serem abordados nas aulas de Química, ocupando um espaço importante no debate de políticas públicas voltadas à educação. Assim, o objetivo deste trabalho foi analisar como o livro didático de Química vem sendo utilizado por professores de Química da Educação Básica nas escolas da rede pública de um município do interior do Amazonas. A pesquisa foi realizada com 10 professores, que responderam a um questionário e participaram de uma entrevista semiestruturada. Percebeu-se que os docentes citam a linguagem didática e a pouca contextualização como fatores que dificultam o uso do livro em sala de aula. Além disso, os docentes compreendem que não se deve limitar-se apenas a esse recurso, e por isso fazem o uso de sites, blogs e vídeos de modo a levar seus alunos a uma melhor compreensão dos conteúdos abordados.
Pengkajian Transdisipliher dalam llmu Sosial di Indonesia

Published: April 2022

Masyarakat ilmuwan merupakan pejuang untuk memajukan bangsanya. Di bidang apapun ilmuwan selalu dihadapkan pada pilihan yang kadangkala amat sulit. Dalam pada itu lembaga-lembaga atau pusat-pusat penelitian di universitas menggantungkan tenaga penelitinya pada para dosen. Mengapa pusat-pusat penelitian tidak dikembangkan melalui pengangkatan tenaga peneliti yang tidak harus menjadi dosen pengajar di fakultas? Hal ini penting untuk dipikirkan, karena bagaimanapun perkembangan ilmu tidak mungkin terjadi tanpa penelitian. Ilmu-ilmu sosial di Indonesia, termasuk ilmu ekonomi, harus diakui belum cukup menggembirakan perkembangannya. Hal ini terutama disebabkan perguruan tinggi kita belum menjadi pusat-pusat penelitian, tetapi baru menjadi pusat pengajaran dan pengabdian kepada masyarakat. Agar perguruan tinggi bisa menjadi pusat-pusat penelitian diperlukan persyaratan, antara lain berupa pembukaan dan pemberian peluang pengembangan karier peneliti. Pusat-pusat penelitian perlu diberi kesempatan mengangkat tenaga-tenaga peneliti yang bukan dosen (tenaga pengajar), dan selanjutnya disediakan dana-dana penelitian yang memadai. Pemerintah perlu secara serius mengembangkan iklim yang merangsang penelitian dan menerbitkan hasil-hasilnya, termasuk diantaranya konperensi-konperensi antar peneliti dari pusat-pusat penelitian dan fakultas.
