A “cultura clássica" e a "subcultura" na magistratura: um diálogo entre ativismo judicial e os seus limites
Authors: Vitorio Marcelo Diego Gomes da Silva
Published: February 2020

O presente artigo tem por escopo delinear as possíveis respostas acerca dos limites entre o ativismo judicial e a posição dos magistrados frente aos processos. Nesse sentido, foi procedida uma análise de algumas decisões judiciais que repercutiram na comunidade jurídica e na sociedade brasileira, com o fim de lançar um olhar crítico acerca do contraponto entre as posições ativistas e “clássicas” na magistratura. Esse debate se torna cada vez mais relevante no Brasil, uma vez que, nos últimos anos, algumas decisões judiciais impactaram grandemente a sociedade brasileira e, por extenso, os magistrados por trás dessas decisões ganharam notoriedade. Em conclusão, tendo em vista o princípio da harmonia entre os poderes constituídos da república, observou-se que as decisões judiciais ativistas influenciaram substancialmente a ordem democrático-constitucional brasileira, ensejando uma reanálise profunda por parte da comunidade jurídica a respeito dos limites desse ativismo judicial.

A insuficiência de nutrientes essenciais na alimentação é um problema complexo de saúde pública, sendo responsável pela interrupção permanente ou momentânea da qualidade de vida de pessoas em todas as faixas etárias. Com aumento das doenças associadas à obesidade, deve-se orientar para a redução da carência dos nutrientes indispensáveis à conservação da saúde que prejudica o bem-estar das pessoas, contribuindo para que fiquem doentes com mais facilidade. A doença celíaca é uma reação auto autoimune a proteína prolamina presente no glúten, em indivíduos geneticamente vulneráveis e, que provoca enteropatia. As indústrias de alimentos estão se adaptando as legislações da ANVISA, que determina a declaração nos rótulos da informação nutricional obrigatória de valor energético, carboidratos, proteínas, gorduras totais, gorduras saturadas, gorduras trans, fibra alimentar e sódio. O presente artigo teve como objetivo desenvolver uma torta à base de grão-de-bico com castanha do Brasil e cenoura e avaliar sua composição nutricional. O estudo foi do tipo transversal quantitativo de característica descritiva, de desenvolvimento de um novo produto, com cálculo da informação nutricional, com base na RDC nº 360, RDC nº 359 para definição da porção, e a RDC 54. Por meio da pesquisa ficou constatado que o produto é uma preparação saudável, por apresentar alto teor de proteínas e de fibras alimentares conforme classificação pela RDC nº 54, baixo teor de sódio e de gorduras saturadas quando comparado com uma torta de frango industrializada.

Published: February 2020

Grande parte dos efluentes produzidos por indústrias e domicílios são lançados no ambiente tornando-se altamente nocivos aos seres vivos e ao ambiente. Muitos destes efluentes apresentam em sua composição metais pesados. Os metais pesados podem favorecer a inativação de algumas enzimas essenciais para o metabolismo celular causando diversos danos à saúde. Em efluentes líquidos há diversas técnicas que podem ser empregadas na remoção desses contaminantes, entretanto, alguns desses métodos apresentam custo elevado, baixa remoção do metal e alta demanda de reagentes. Uma perspectiva crescente, é o uso de materiais de origem biológica para remoção dessas substâncias nocivas. Neste trabalho, buscamos realizar uma revisão de literatura (1997-2019) acerca de métodos alternativos, especialmente os biotecnológicos como biossorção e fitorremediação, para remoção de metais pesados do meio aquoso. Tais técnicas foram escolhidas por apresentarem baixo custo associado e serem ecologicamente favoráveis. Para biossorção, encontramos diferentes subprodutos de origem vegetal capazes de remover diversos íons metálicos, como a casca de laranja, coco verde, folhas de bananeira e sementes. Fungos (Pleurotus ostreatus), bactérias (Bacillus licheniformis) e microalgas (Spirulina platensis) também foram descritos como bons removedores de metais pesados. As plantas, por meio da fitorremediação, também demonstraram-se eficazes, notadamente as espécies: Lemna aequinoctialis, Helianthus annuus, Commelina benghalensis. Zea mays, Amaranthus hybridus, Pistia stratiotes. Nesta perspectiva, podemos concluir que os processos de biossorção e fitorremediação empregando produtos/subprodutos vegetais, microbianos ou animais são viáveis pelo seu baixo custo e boa disponibilidade, além de apresentarem taxas expressivas na remoção de substâncias recalcitrantes, notadamente de metais pesados.

A leishmaniose tegumentar americana (LTA) é uma doença infecciosa causada por protozoários do gênero Leishmania que provoca úlceras na pele e mucosas. O objetivo da pesquisa foi verificar a incidência da leishmaniose tegumentar americana no município de Cacoal-RO no período de 2010 a 2018. A metodologia é do tipo transversal, documental, descritivo e quantitativa. As informações foram fornecidas pela vigilância em saúde do município atendidos nas unidades básicas de saúde, ambulatório e hospitais público/ privado, os dados foram tabulados utilizando um questionário elaborado pelos próprios pesquisadores contendo 4 perguntas básicas baseadas na ficha de notificação compulsória do SINAN. Verificou-se que no município de Cacoal-RO foram notificados 395 casos de leishmaniose tegumentar americana entre 2010 a 2018, sendo 89,62% no sexo masculino e 10,38% no sexo feminino 86,6% das notificações na faixa etária de 19 a 59 anos e 46,34% dos pacientes na cor parda, 91,13% dos pacientes apresentaram lesão cutânea e 10,67% apresentaram lesão de mucosa e 94,68% foram classificados como casos novos. Os diagnósticos dos pacientes foram confirmados 94,93% por meio laboratorial, sendo utilizado o por antimonial pentavalente em 95,95% dos pacientes. 58,48% dos pacientes eram pertencentes a zona urbana e 41,52% zona rural do município de Cacoal-RO. Conclui-se que a incidência dos casos de Leishmaniose tegumentar americana no município de Cacoal-RO tem aumento significativo anual correspondendo cerca de 1 caso a cada 100 habitantes. Torna-se necessário medidas preventivas por meio de orientações sobre a doença e sintomas, visto que, o uso de repelentes já diminuiria a incidência.
Is Corporate Social Responsibility Performance Related to Conditional Accounting Conservatism?
Authors: Burke Qing L. , Chen Po-Chang , Lobo Gerald J.
Published: February 2020

SYNOPSIS

We examine the relation between corporate social responsibility (CSR) performance and conditional accounting conservatism. Drawing upon the stakeholder-engaging and information-enhancing perspectives of CSR activities, we hypothesize that the demand for conditional conservatism, which primarily arises from various contracting parties' concern about managerial opportunism and/or information asymmetry, is lower for better-performing CSR firms. Using the CSR ratings from the KLD database, we find, as predicted, a negative relation between CSR performance and conditional conservatism. These findings are robust to using a difference-in-differences research design and alternative measures of conditional conservatism. Further, cross-sectional analyses reveal that the negative association is more pronounced for firms with greater information asymmetry and stronger corporate governance. Overall, this study enhances our understanding of how a firm's CSR engagement may relate to an important attribute of financial reporting.

Authors: Francisco de Andrade Alvarenga José
Published: February 2020

O presente artigo tem como objetivo investigar a recepção da obra de Marx em Althusser. Analisa-se em maior profundidade a leitura desenvolvida por Althusser a respeito do papel ocupado pela obra do jovem Marx no desenvolvimento do pensamento do filósofo alemão. Com base na análise de textos e livros publicados por Althusser durante a década de 1960 e 1970, conclui-se que a recepção de Marx por Althusser foi marcada pela busca de uma atualização da filosofia marxiana de modo que ela pudesse estar em condições de adentrar o debate filosófico-político desenvolvido na França na década de 1960.
Brasil 2013-2018:
Authors: Emanuel de Souza Coelho David
Published: February 2020

O artigo visa interpretar a situação brasileira entre os anos de 2013 e 2018 enquanto um processo de dissolução do antigo regime político chamado de Nova República. As manifestações de 2013 são consideradas enquanto o momento inicial deste processo dissolutivo, e teriam por origem, conforme argumenta-se no artigo, a partir das contradições insolúveis da Nova República entre as pretensões reformistas da constituição de 1988 e a permanência de uma estrutura econômica e social excludente. No período da Nova República, teria vigido uma forma política de cidadanismo, agora substituída por uma formatação política belicista, bem encarnada no bolsonarismo.

Venezuela and its Neighbors: The Discursive Struggle for Latin America
Authors: Pérez José Oviedo
Published: February 2020

Over the past decade, Venezuela has entered into a deep recession, which has resulted in millions migrating abroad. In February of 2019, the United States and its allies recognized the interim government of Juan Guaidó, creating a standoff with the Chavista government of Nicolás Maduro. This article conducts a nuanced analysis of the situation in Venezuela across multiple levels as it problematizes our ontological understanding of individuals, states, and international system. Through a post-structuralist approach to security, I argue that individuals have been portrayed in contradictory humanitarian discourses as a means of advancing particular political interests. Furthermore, I critically analyze the role of space, time, and multilateralism, and their subsequent effects for 21stcentury global order.

Values and electoral behavior of Russian citizens at presidential elections (2012, 2018): constancy and variability
Authors: Averin Yu. P. , Sushko V. A.
Published: February 2020

Based on the empirical data of two sociological studies conducted in accordance with the uniform methodology using the personal questionnaire method in April 2012 and May 2018 (almost immediately after the election of the President of the Russian Federation), the article analyzes the structure of values of Russian urban voters, influencing their attitude to participation in the presidential elections and to the competing candidates. The socio-economic and socio-political conditions in Russia and their influence on the structure of values of urban voters are considered in the article. The article reveals the reasons why the fewer urban voters participated in the elections and a much larger number of them voted for Vladimir Putin when the economic situation of voters deteriorated in 2012 compared to 2018.

The article shows that the structure of values of urban voters remains predominantly “materialistic” (according to Ronald Inglehart). The influence of the value structure of voters on their participation in voting at the presidential election and on the support of a certain candidate is revealed. On the basis of comparing the results of the presidential elections in 2012 and 2018, it is shown that during 6 years the ideological spectrum of candidates has expanded and began to express a wider range of political views on the further development of Russian society and state — from extremely liberal, democratic to extremely conservative, totalitarian, which is essential feature of the modern Russian party and political system. The middle of this spectrum was represented by liberal conservatism of Vladimir Putin, and his support in 2018 reflects a shift in the values of urban voters from the extreme right and the extreme left to the middle, toward liberal conservatism that is becoming inherent in an increasing number of urban voters.

It is revealed that within the framework of the “materialistic” value structure of urban voters, the value of material wealth does not play a significant role when voters choose the future development of Russia. The value of unselfish patriotism and family is in the first place. The difficult political conditions in Russia in 2018 gave the voters patriotism a militant character that was absent in 2012. It united Russian society around Vladimir Putin even more and was the cause of a significant increase in his support from voters. Liberal component of conservatism in the program of Vladimir Putin (the expansion of economic, political, and spiritual freedoms) led to his support from moderately liberal voters. All these factors together predetermined the great success of Vladimir Putin in the presidential elections in Russia in 2018.

A resilience-based approach to enhance the capacity of small villages to cope with intertwined threats
Authors: Galderisi Adriana , Limongi Giada
Published: February 2020

About 70 percent of Italian municipalities that have fewer than 5,000 inhabitants are located in difficult to access mountain areas which are often prone to multiple hazards. As clearly demonstrated by the seismic events that hit Central Italy in 2016, the socio-economic decline of these municipalities is also increasing their vulnerability. Nowadays, small villages represent an important challenge for Italy, because they require significant resources and effective strategies to both break the cycle of decline and promote their economic and social development, while also reducing their vulnerability to natural and climate related hazards. This contribution provides an overview of the initiatives recently launched in Italy in favour of small villages and outlines a methodological path to assess and enhance the overall resilience of these areas, with a focus on a case study area located in the Basilicata Region of Southern Italy.

Озеро Куэтсъярви (нижнее течение р. Пасвик, Мурманская область), расположенное в приграничной зоне между Россией и Норвегией, является одним из наиболее загрязненных водоемов Евро-Арктического региона. В результате деятельности расположенного на его берегах плавильных цехов металлургического комбината «Печенганикель» в водах и донных отложениях озера отмечаются чрезвычайно высокие концентрации тяжелых металлов. Долговременные комплексные исследования экосистемы оз. Куэтсъярви позволили выявить ответные реакции ее компонентов на глобальные и региональные изменения окружающей среды и климата в целом, результирующие в усилении токсификации вод и их эвтрофировании, сокращении численности стенобионтных видов гидробионтов на фоне возрастания численности эврибионтных и инвазивных видов. Современные сообщества оз. Куэтсъярви представляют собой результат воздействия комплекса факторов многолетних изменений абиотической среды и биотических взаимоотношений. Загрязнение оз. Куэтсъярви тяжелыми металлам, длящиеся с 30-х годов прошлого века, привело к формированию сообщества, устойчивого к данному виду воздействия и поддерживающего высокую численность толерантных и адаптированных организмов. Адаптации сообществ к динамике условий существования организмов, выражаются в изменениях видового состава, количественных показателей, соотношения отдельных таксономических групп, структуры популяций. Формирование симпатрических форм, различающихся экологическими нишами, морфологией, стратегиями жизненного цикла, включая переход на короткоцикловую стратегию выживания, позволяет сигу оставаться доминирующим видом и поддерживать высокую численность популяции. В отличие от организменного уровня, ответные реакции на среднесрочные изменения окружающей среды популяций и сообществ более инерционны и менее специфичны.

В связи с осуществляемой программой по очистке арктического побережья России от жидких радиоактивных отходов (ЖРО), накопленных за время функционирования атомного флота, возникает проблема дезактивации больших объемов регламентных ЖРО, а также малых и средних объемов ЖРО, для которых технологические регламенты переработки отсутствуют. В настоящее время не существует технологических процессов, позволяющих производить комплексную одностадийную очистку жидких радиоактивных отходов с возможностью дальнейшего долговременного захоронения продуктов очистки. Наши исследования показали, что для очистки нерегламентных ЖРО может быть успешно использован новый нанокристаллический сорбент LHT-9 (слоистый титанат гидразина), способный удалять из водных растворов более 50 химических элементов, в том числе большинство радионуклидов, включая 137Cs, 90Sr, 93Zr, 151Sm, 154Eu, 99Tc, 79Se, 107Pd, 126Sn, 238U, 235U, 239Pu, 237Np, 243Am. Быстрая одноактная очистка регламентных ЖРО реакторов водно-водяного энергетического типа от радионуклидов Cs, Sr и Co может быть проведена при помощи еще одного нового сорбента – минерала иванюкита (микропористый титаносиликат натрия), селективного в отношении этих элементов. Одновременное либо последовательное использование разработанных сорбентов с учетом их устойчивости в растворах любой кислотности-щелочности позволяет полностью решить проблему дезактивации и отверждения ЖРО практически любого химического состава. В статье вводится понятие «геоника» – инженерно-технологическое воспроизведение и использование уникальных свойств природных минералов для решения прикладных задач, по аналогии с бионикой.

Authors: Khadouri Hanan Kamal , Kandhan Karthishwaran , Salem Mohammed Abdul
Published: February 2020

Managing water consumption of the crops is one of the strategies which have been adopted locally and worldwide in current trends of sustainable agriculture. In addition to the low level of water resources in UAE because of the rare precipitation, no fresh, free-flowing water, rivers, lakes or streams. The present study was aimed to evaluate the effects of exogenous Glycine Betaine (GB) on Alfalfa (Medicago sativa) and Cowpea (Vigna unguiculata) within different levels of drought stress. A pot experiment was designed on a completely randomized block design (CRBD) with three replicates. Exogenous GB was applied as a foliar spray in three levels (0,100 and 200 ppm) five times with five days intervals. Drought stress starts within the second GB treatment in three levels (24h: 100% well-watered), (48h: 60% water deficit) and (72h: 40% water deficit) depending on the required quantity. Growth characteristics, pigment concentrations, biochemical content and Mineral nutrients levels were measured in response to the treatment variables. Results showed that the GB has a significant increment in Growth parameters, biochemical contents, and Mineral nutrients concentrations. The results of the present investigation suggested that the exogenous application of GB was improved the drought tolerance in Cowpea and has enhanced the Alfalfa performance under drought stress in both concentrations 100 and 200 ppm under drought stress of 60% of irrigations water.  In due of comparison of Cowpea and Alfalfa, it’s found from this study that GB has a better effect on the Cowpea under drought stress than Alfalfa.
Democracia y libertad en B. Spinoza

Negar el libre albedrío implica que el ser humano no es libre por naturaleza, sino que puede llegar a serlo mediante un uso adecuado de su inteligencia; libertad que solo la consiguen los “sabios”. Por eso, cuando Spinoza entiende la democracia como la forma de gobierno que mejor defiende la libertad, esto vale para los “sabios”, pero no para el vulgo, que solo mediante el miedo y la esperanza es conducido a obrar según los dictados de la razón. ¿No será esta indeseable consecuencia la que le impidió terminar su Tratado Político, precisamente cuando se aprestaba a estudiar la democracia?

A Systematic Method for Predictive in-silico Chemical Vapour Deposition
Authors: Danielsson Örjan , Karlsson Matts , Sukkaew Pitsiri , Pedersen Henrik , Ojamäe Lars
Published: February 2020

A comprehensive systematic method for chemical vapour deposition modelling consisting of seven well defined steps is presented. The method is general in the sense that it is not adapted to a certain type of chemistry or reactor configuration. The method is demonstrated using silicon carbide (SiC) as model system, with accurate matching to measured data without tuning of the model. We investigate the cause of several experimental observations for which previous research only have had speculative explanations. In contrast to previous assumptions, we can show that SiCl2 does not contribute to SiC deposition. We can confirm the presence of larger molecules at both low and high C/Si ratios, which have been thought to cause so-called step-bunching. We can also show that high concentrations of Si lead to other Si molecules than the ones contributing to growth, which also explains why the C/Si ratio needs to be lower at these conditions to maintain high material quality as well as the observed saturation in deposition rates. Due to its independence of chemical system and reactor configuration, the method paves the way for a general predictive CVD modelling tool.

Sclareol has demonstrated a broad variety of biological activities that belong to the antioxidant anti-inflammatory and anticancer activities that are used in traditional medicine. In the current study, we intended to explore the antitumor possible of sclareol along 7, 12-dimethylbenz (a) anthracene (DMBA) evoked golden Syrian hamster’s buccal pouch carcinogenesis. Lipid peroxidation and antioxidants were assessed by the buccal tissue, and plasma of DMBA evoked golden Syrian hamster buccal pouch carcinogenesis of observational animals. We observed 100% of tumor establishment and noted defects in the biochemical restrictions of lipid peroxidation and antioxidants and also histopathological observations of carcinogenesis in the hamster’s buccal pouch in DMBA only. Sclareol (20 mg/b.wt) has significantly inhibited the tumor burden, tumor volume, and increased phase II detoxification enzymes, antioxidant level, lipid peroxidation, and also phase I enzymes and has improved the histopathologically changes during carcinogenesis in the buccal pouch of  DMBA induced golden Syrian hamster. The outcomes of the present scrutinized study proposed that aiming biochemically and histopathologically that act upon the inheritance of cancer characteristics is an effectual system for chemoprevention. Therefore, our results resolved that sclareol has probably owing to its antioxidant or scavenging properties of free radical and transition act on phase I and II enzymes in regards to the evacuation of metabolites carcinogenesis, which is evoked by DMBA in hamster’s buccal pouch.

A RESTRIÇÃO DA TUTELA DE DIREITOS INDIVIDUAIS HOMOGÊNEOS DE NATUREZA TRIBUTÁRIA E O DIREITO FUNDAMENTAL DE ACESSO À JUSTIÇA
Authors: Gagno Luciano Picoli , Gomes Mariana Santos Camara
Published: February 2020

O presente artigo tem o escopo principal de analisar a restrição existente sobre a utilização de ações coletivas para a tutela de direitos individuais homogêneos de natureza tributária, contrapondo-a ao direito fundamental de acesso à justiça e trazendo à baila, especialmente, o parágrafo único do art. 1º da Lei de Ação Civil Pública, introduzido no ordenamento jurídico pela Medida Provisória nº 2.180-35/2001, bem como a interpretação dos tribunais superiores, antes e depois da vigência do referido diploma normativo. Para realizar este trabalho, foi utilizado o método dedutivo por meio de pesquisa exploratória bibliográfica e documental, dentre artigos científicos, legislação, jurisprudência e doutrinas jurídicas. Assim, o desenvolvimento foi distribuído em três seções, sendo que a primeira trabalha os aspectos gerais da tutela coletiva, destacando as espécies de interesses ou direitos coletivos, bem como os legitimados e os efeitos da coisa julgada, visando à situação do leitor no particular sistema jurídico das ações coletivas. O segundo seleciona e apresenta alguns importantes julgados a fim de trazer o posicionamento dos tribunais superiores, em especial do STJ, acerca do tema, para, finalmente, chegarmos a terceira e última seção, que traz a análise crítica, à luz do direito fundamental do acesso à justiça, foco principal deste trabalho. As considerações finais dão conta de que o parágrafo único do art. 1º da Lei de Ação Civil Pública vai totalmente de encontro com o direito fundamental de acesso à justiça, o que releva a sua flagrante inconstitucionalidade. Paralelamente, considerando-se a realidade fática e jurídica existente, se propôs que, diante do referido texto normativo, que nunca foi declarado inconstitucional, se alcance, ao menos, uma aplicação reduzida, que restrinja minimamente a tutela dos direitos de natureza tributária, com o objetivo principal de se permitir, em caráter difuso, a proteção dos contribuintes contra a cobrança indevida de tributos.

ABSTRACT

In this study, a microstrip antenna (MSA) was developed with the addition of a double U-slot to improve bandwidth performance. Previous studies have focused on adding single U-slots and designed for frequencies below 15 GHz. The main requirement for 5G antennas is high bandwidth performance and multiple inputmultiple output capabilities (MIMO). Therefore, it is necessary to develop a 5G MIMO antenna with broader bandwidth at the millimeter-wave frequency 28 GHz as the primary candidate for frequency allocation for 5G cellular communication. In this study, MIMO antenna design techniques were proposed with the addition of a double U-slot method to improve bandwidth performance. The calculation and simulation results show that with the addition of a double U-slot, an increase in bandwidth performance of 68% compared to antenna designs without U-slots and 76% when compared to using a single U-slot in previous studies.

We examine a rectangular cavity resonator method to accurately characterize the complex permittivity of dielectric materials over a wide frequency range of 1–5 GHz by exploiting the fundamental mode and higher-order TE(1,0,l) modes. For this purpose, a rectangular waveguide is coupled with a cavity resonator through a large inductive aperture. The permittivity characterization at both even and odd TE(1,0,l) modes enables continuous determination of the permittivity over operating frequencies. The characterization of the permittivity for even TE(1,0,l) modes suffers from potential errors due to the displacement of materials. This paper also proposes a method to compensate for these errors and improve the accuracy in the even modes. The experimental results of the fabricated cavity are presented using different materials (frequency-independent and frequency-dependent). The measured complex permittivity results show a good agreement with the reported results over a wide bandwidth available in the literature.
Design of a Small Array Antenna with an Extended Cavity Structure for Wireless Power Transmission
Authors: Hur Jun , Choo Hosung
Published: February 2020

This paper proposes a design of a small array antenna with an extended cavity structure for wireless power transmission. The proposed array element consists of a square radiating loop, which is designed to resonate at 5.8 GHz, and an extended cavity structure to reduce the mutual coupling between adjacent elements. We derive the optimal element number in a limited space by considering the input power for each element, fabrication cost, and aperture efficiency of the system. To verify the suitability of the proposed a small array with an extended cavity structure, a 2 × 2 downscaled array antenna is fabricated and measured in a full anechoic chamber. The results confirm that the proposed antenna element with an extended cavity structure is suitable for wireless power transmission systems; the proposed array has a transmission efficiency of about 1% at a distance of 2 m when the array is applied to both transmitting and receiving antennas.

Published: February 2020

Although universities and their faculty design courses for periodic learning, the “new learning society,” an increasingly diverse, mobile population is inexorably shifting to a model of continuous, self-directed, lifelong learning. Hence, the effective instructional practices that emerge through the role of the MOOC instructor have lasting value, whether the trend of MOOCs endures, or not. Understanding faculty experiences can inform online teaching as well as facilitate the success of MOOCs and other online offerings within and beyond the university. It can also help both faculty and learners thrive in a new learning society. As part of a larger study, this paper reports on the impact of online teaching on instructors’ pedagogical approaches. A key finding is that instructors improved their residential teaching by incorporating MOOC material into their courses; online format also forced instructors to think of both their subject matter and the presentation of their content in better and more inclusive ways.

This paper presents and discusses the use of simulation-based customizable online learning activities, virtual laboratories, and comprehensive e-Learning environments for teaching subjects such as materials science, chemistry, and biomanufacturing. The virtual equipment and lab assignments have been used for: (i) authentic online experimentation, (ii) homework and control assignments with traditional and blended courses, (iii) preparing students for hands-on work in real labs, (iv) lecture demonstrations, and (v) performance-based assessment of students’ ability to apply gained theoretical knowledge for operating actual equipment and solving practical problems. Using the associated learning and content management system (LCMS) and authoring tools, instructors kept track of student performance and designed new virtual experiments and more personalized learning assignments for students. Virtual X-Ray Laboratory and Web-based Environment for Single-Use Upstream Bioprocessing have been used to illustrate the implementation of the concept of Interactive and Adjustable Cloud-based e-Learning Tools. The virtual labs and e-learning environments have been used at two-year and four-year colleges and universities in the USA, UK, Tanzania and some other countries. The virtual X-Ray lab has also been integrated with the MITx course delivered via the MOOC (massive open online course) edX platform for Massachusetts Institute of Technology undergraduate students.

Indian Educational Technology under a Learning Sciences Lens
Authors: Saxena Nilanjana
Published: February 2020

Education delivery and design is being continuously recast by application of learning technology. Several web-based learning applications are contributing to accessibility, enabling differentiated learning needs at scale. No doubt this is an important first step towards education for all, however since learning is a complex socio-psychological experience, are current EdTech products simply replicating traditional teaching? This paper presents a Learning Science (LS) perspective on EdTech solutions emerging in India, aimed at examining their pedagogical efficacy and proposing recommendations for greater cognitive engagement. Results reveal that while teacher centred approaches are visible in the Indian EdTech products, designing products aimed at constructive and interactive learner tasks will likely pave the way for higher learning gains.

Modeling and optimization of technological process and means of mechanization of grain production for middle China based on Belarusian technology
Authors: Li Qingzhen , Leonov A. N.
Published: February 2020

One of the main problems in grain production in China is the high level of unit costs (high cost price). The main reason is the low level of mechanization. Development of efficient technologies and means of mechanization is a promising area allowing to decrease the level of unit costs at a given labor efficiency and maintaining the achieved yield. Grain production is a complex system associated with a large amount of information: agro-technological (crop variety, crop yield, physical-and-mechanical parameters of land plots, terms of operations, permissible speed range for specific operations, etc.), technical-and-economic (power and traction parameters, throughput, working width, operating weight, hopper volume , cost). At present, efficient methods for studying complex systems have appeared as a result of development and widespread implementation of computer mathematics systems, which allow us to study mechanization technologies and tools using multi-factor modeling and multi-criteria optimization. The paper presents a multi-factor mathematical model, peculiar for the fact that the three groups of simultaneously varying factors are taken for the first time engine power, MTA speed, timing of the main energy-intensive operations – plowing, harvesting, and as conflicting optimization parameters unit cost level, coefficient of crop losses, labor efficiency, which allowed a comprehensive study of the grain production process in any natural-production conditions. A technological process has been developed (units speed and timing of the main operations (plowing, harvesting) and the corresponding range of machines and equipment, ensuring minimum level of unit costs at a given labor efficiency and maintaining the achieved crop yield, taking into account the specifics of the Middle China (2 crops per year).

Ikan karang merupakan ikan bernilai ekonomis tinggi dan sering dimanfaatkan sebagai target tangkapan oleh nelayan. Keberhasilan pemanfaatan ikan karang agar optimal didukung oleh beberapa faktor, salah satunya daerah penangkapan ikan. Namun kondisi yang terjadi di masyarakat Pulau Kei Besar adalah bahwa mereka belum mengetahui daerah penangkapan ikan yang potensial. Tujuan penelitian ini  adalah menghitung kekayaan jenis dan indeks ekologi ikan karang di perairan pesisir timur Pulau Kei Besar, mengidentifikasi kelimpahan ikan karang yang layak tangkap di perairan pesisir timur Pulau Kei Besar, serta menentukan daerah potensial penangkapan ikan karang di perairan pesisir timur Pulau Kei Besar. Penelitian ini berlangsung dari Oktober 2018 hingga Februari 2019 dimana pengambilan data lapangnya mengambil 9 titik lokasi pada tanggal 3–18 November 2018 dengan menerapkan metode Underwater Visual Census. Analisis yang dilakukan adalah menghitung kelimpahan ikan, biomassa, komposisi jenis, indeks ekologi, ukuran layak tangkap dan pembobotan untuk menentukan daerah penangkapan ikan potensial. Hasil penelitian menunjukkan bahwa kelimpahan dan biomassa ikan paling tinggi terdapat di lokasi Fako dengan 4 dari 9 lokasi pengamatan memiliki persentase jenis ikan yang sudah layak tangkap lebih besar daripada yang belum layak tangkap. Lokasi perairan Kilwait, Ohoirenan, Ngufit Bawah, dan Yamtel bukan daerah yang potensial untuk menangkap ikan karang. Perairan Weduar, Hollat, dan Ohoifau merupakan perairan yang cukup potensial untuk menangkap ikan karang serta perairan Ohoiwait dan Fako merupakan perairan yang potensial untuk menangkap ikan karang. Penelitian ini diharapkan dapat bermanfaat dalam memberikan informasi kepada nelayan terkait daerah penangkapan ikan agar kegiatan penangkapan ikan yang dilakukan lebih optimal.
