Peculiarities of Land Reform and Introduction of the Land Market in Ukraine: Legal Security and Consequences
Authors: Zyhrii Olha
Published: September 2021

During the years of Ukraine's independence, the issue of land reform and the opening of the market for agricultural land was on the agenda of the legislative and executive branches of government. According to the Constitution of Ukraine, land is the most valuable wealth and property of the Ukrainian people. Land reform is not the first attempt by the authorities to change land relations in Ukraine, but it was to resolve the controversial issues of Ukrainian land. The implementation of land reform provided not only the introduction of effective mechanisms of land tenure and land use, but also the development of a modern land market on the basis of a market economy. Land reform has been hampered by corruption, a moratorium on the sale of agricultural land, and the desire of some politicians to speculate on the issue. Therefore, the moratorium in Ukraine was introduced as a temporary tool to protect landowners in the underdeveloped infrastructure of the land market. The adopted Law of Ukraine in 2020 removes the moratorium and gives the right to owners of agricultural land to dispose of their land at their own discretion. In the future, the opening of the land market should be a significant change in the life of Ukrainian society. However, the villagers face a number of unresolved issues that need to be clarified. Parliament and the government are expected to adopt and implement new land laws, such as decentralization of land management, the state e-auction, and the establishment of an independent Partial Lending Fund to increase smallholder access to flexible financing.
Frankreich und die Türkei – Machtpoker ohne Sieger
Authors: Kempin Ronja
Published: September 2021

In the summer of 2020, Franco-Turkish relations deteriorated dramatically. Since then, Paris has accused Ankara of deliberately influencing the Turkish diaspora in France in order to undermine the values of the French Republic. In terms of foreign policy, France criticizes Turkey for encircling the European Union (EU) and its member states with the consequence of deliberately acting against their interests. Neither the ideological nor the geopolitical power poker of the two states has produced a winner. The Franco-Turkish rivalries offer the EU the opportunity to undertake a comprehensive reorientation of its Turkey policy. The expansion of its conditionality to include domestic political issues is just as important as an improved division of roles and work in its institutions and the geopolitical view of the respective neighbourhood.

Published: September 2021

The area of Wireless Sensor Networks (WSN) bring a new era of connected on-demand embedding systems which are mostly resource constrained. Despite of having design and operational challenges in real-time, WSN is currently being deployed for wide range of applications where traditional networking systems are most of time unfeasible. The prime focus of the study is to realize the significance of energy efficient routing in WSN. The core motivation is derived by addressing energy problems of WSN. An extensive analysis drawn from reviewing literatures, clearly shows that very few studies incorporated optimization towards modeling the routing schema. This chapter introduces a methodology consisting of three different types of analytical modeling where two of them focus on energy efficient clustering and another one is integrated to attain higher degree of security during data aggregation. The chapter basically provides an insight into the background of the problem which is related with the energy and security in WSN and also further provides preliminary information regarding the research overview. Further the study performs a thorough investigation on existing literatures to extract the open research problem. It basically highlights the gap which still exists and does not meet the requirements of proper energy and security demands. Literature survey on hierarchical protocols of WSN and their basic characteristics towards energy conservation is performed.

The Nanocellulose Fibers from Symbiotic Culture of Bacteria and Yeast (SCOBY) Kombucha: Preparation and Characterization
Authors: Aditiawati Pingkan , Dungani Rudi , Muharam Salsabila , Sulaeman Aminudin , Hartati Sri , Dewi Mustika , Rosamah Enih
Published: September 2021

Symbiotic Culture of Bacteria and Yeast (SCOBY) is a by-product in the form of cellulose polymers produced by bacteria in the kombucha fermentation process. Until now, SCOBY products still have application limitations. Several world designers have succeeded in making works using fabrics based on SCOBY. The resulting fabric has a flexible texture and is brown like synthetic leather. Fabrics based on SCOBY are also considered cheap and more environmentally friendly with short production time. The use of SCOBY as a fabric base material still has problems, where the fabric produced from SCOBY kombucha, directly through the drying process, has the characteristic of being very easy to absorb water. Another problem is that SCOBY production in the kombucha fermentation process is difficult to achieve a uniform thickness and SCOBY production in a large surface area is also difficult to stabilize. The development of SCOBY into cellulose fibers can be done by first changing the structure of SCOBY into nanocellulose. This nanocellulose production can then be developed into nanocellulose fibers in the form of threads and then spun to become a complete fabric. The production of nanocellulose is carried out using cellulase enzymes. It is known that cellulase enzymes can be obtained through the growth of bacteria or specific fungi. One of the groups of fungi and bacteria commonly used to produce cellulase enzymes are Trichoderma and Bacillus.

Data Mining Applied for Community Satisfaction Prediction of Rehabilitation and Reconstruction Project (Learn from Palu Disasters)
Authors: Irfan Rifai Andri
Published: September 2021

Natural disasters can occur anytime and anywhere, especially in areas with high disaster risk. The earthquake that followed the tsunami and liquefaction in Palu, Indonesia, at the end of 2018 had caused tremendous damage. In recent years, rehabilitation and reconstruction projects have been implemented to restore the situation and accelerate economic growth. A study is needed to determine whether the rehabilitation and reconstruction that has been carried out for three years have met community satisfaction. The results of further analysis are expected to predict the level of community satisfaction for the implementation of rehabilitation and other reconstruction. The method used in this paper is predictive modeling using a data mining (DM) approach. Data were collected from all rehabilitation and reconstruction activities in Palu, Sigi, and Donggala with the scope of the earthquake, tsunami, and liquefaction disasters. The analysis results show that the Artificial Neural Network (ANN) and the support vector machine (SVM) with a DM approach can develop a community satisfaction prediction model to implement rehabilitation and reconstruction after the earthquake-tsunami and liquefaction disasters.

Published: September 2021

The state of Meghalaya is situated in the north-eastern India and it comprises three major regions, namely, the Khasi Hills, the Jaintia Hills and the Garo Hills inhabited by three main tribal groups, the Khasis, the Jaintias and the Garos respectively. The tribal communities of Meghalaya protect and nurture the forests located close to their habitation and consider them as sacred. These Community reserved forests are managed by the community for their benefits and they comprise almost about 90% of the total forest cover in Meghalaya. With the recent trends of development and construction in the state many habitats are getting destroyed at an alarming rate. These community reserve forests have been seen to provide the maximum number of existing and stable habitats for many amphibian (anuran) species. In addition, they served as suitable sites for the breeding activities and oviposition by anurans. Discovery of many new anuran species have also been reported from such reserved forests.
Evaluation of Weldability based on Alignment Condition of Horns and Anvils used in Multilayered Battery Cell Welding Process in Ultrasonic Metal Welding
Authors: Shin Seungmin , Kim Dongcheol
Published: September 2021

A battery cell has a foil-to-tab structure that is connected with multi-layer foils and a tab, and it is important to secure the weld quality to improve the battery performance. Ultrasonic metal welding (UMW) is widely applied as a technology suitable for battery cell welding because it provides a relative low heat input to welds owing to solid-state welding. In this study, 40 layers of 8 μm Cu foil and one layer of nickel-plated 0.2 mm Cu strip applied to a multilayered battery cell were used to evaluate the weldability of the materials for the UMW process. An experiment was conducted under four alignment conditions of a horn and an anvil to investigate the effect of the alignment on the weldability. The weld quality was classified based on the weld strength, discoloration, and failure mode of the test specimen to obtain a suitable welding range. The effect of the alignment condition on the deformation and weld shape was investigated by observing the cross-section of welds made under the four alignment conditions.
APPLICATION OF THE CL-SYSTEMS TECHNOLOGY FOR WATER INJECTION WELLS AT AN OIL AND GAS FIELD
Authors: Saychenko Liliya , Karantharath Radharkrishnan
Published: September 2021

To date, the development of the oil and gas industry can be characterized by a decline in the efficiency of the development of hydrocarbon deposits. High water cut-off is often caused by water breaking through a highly permeable reservoir interval, which often leads to the shutdown of wells due to the unprofitability of their further operation. In this paper, the application of straightening the profile log technology for injection wells of the Muravlenkovsky oil and gas field is justified. In the course of this work, the results of field studies are systematized. The reasons for water breakthrough were determined, and the main ways of filtration of the injected water were identified using tracer surveys. The use of CL-systems technology based on polyacrylamide and chromium acetate is recommended. The forecast of the estimated additional oil produced was made.

Authors:   Associate Professor of Social Studies and Citizenship, College of Education, Sultan Qaboos University, Oman, Al-Maamari Saif
Published: September 2021

Educational system in Oman is attempting to educate Omani students to be "good" citizens in an increasingly globalized society. However, a few studies that have been conducted until now in Oman revealed a gap between the intentions of the educational policy of teaching citizenship education in the schools and the actual practices of teacher education preparation programs. Therefore, any endeavor to develop citizenship in Oman schools will not achieve its goals without taking teacher education into account both pre-service and in-service. Accordingly, the present study aims to propose a framework for developing citizenship education in the initial teacher education in Oman. This descriptive study highlighted the gap between the policy and practice in social studies teacher education. The international literature reveals that student teachers feel insufficiently prepared to develop citizenship and Omani student teachers are not exceptional. Thus, the present study proposed a framework to incorporate citizenship education in the current teachers' preparation programs. Furthermore, the study reveals the inadequate presence of the topic of citizenship in teacher education. Therefore, teachers' understanding of citizenship becomes shallow, which undoubtedly leads to superficial learning on the part of the students. Therefore, a framework was proposed to develop citizenship in teacher education. This framework consists of the rationale behind the change, the Layout of the ground for change in teacher education, the mechanisms of the change, and the areas of the change.

Published: September 2021

The aim of this research was to estimate the prevalence of Campylobacter in imported broiler drumsticks and wings. During the one-year study period, 138 imported broiler samples (raw wings and drumsticks) were collected and tested from 3 different sellers. Campylobacter spp. were detected and isolated using traditional microbiological methods, identified using a multiplex polymerase chain reaction (PCR) method. The results of PCR products were analysed in agarose gel using electrophoresis. After an epidemiological study, C. jejuni and C. coli strains were selected and the prevalence of virulence genes was evaluated. The study identified Campylobacter spp. in 36 (26.1%) samples – 19 raw wings (27.9%) and 17 raw drumsticks (24.3%) samples were infected with these bacteria. Campylobacter spp. were most frequently detected in raw broiler samples during autumn (September–November) (47.2%) and winter (December–February) (41.6%) periods than spring (March–May) (5.5%) or summer (June–August) (5.5%). Contamination of products was not significantly impacted by the sale location (p > 0.05). The examination of virulence factors of Campylobacter spp. revealed that C. jejuni and C. coli strains contain 2 out of 3 virulence genes – CadF and CdtA. The CdtA gene was found in nearly all tested Campylobacter spp. strains isolated from broiler samples (94.4%).

O diagnóstico organizacional é uma ferramenta que permite a visualização global da organização através do mapeamento sistemático de condições passadas, presentes e futuras afim de visualizar possibilidades de melhoria. Para realizar tal diagnóstico é preciso recorrer a ferramentas consolidas cientificamente. No presente estudo se objetivou descrever o processo de mapeamento da realidade de uma Agência X do IBGE através de ferramentas de diagnóstico organizacional. Para tanto, se utilizou de um estudo de caso, descritivo e de abordagem quantitativa e qualitativa, que utilizou de três ferramentas de diagnóstico organizacional: Cadeia de Valor, Análise SWOT e Matriz GUT. Os dados foram tratados, apresentados em figuras, quadros e tabelas e analisados de maneira estatística e qualitativa. No estudo se percebeu um claro ordenamento da organização em relação as atividades que promovem o seu objetivo principal de gerar estatísticas necessárias à sociedade, a existência de fatores positivos tais como credibilidade do órgão e fatores negativos, tais como a alta probabilidade de recusa da população às pesquisas, como problemas relacionados à rotatividade de pessoal devido ao alto índice de servidores temporários, bem como problemas cotidianos relacionados aos transportes utilizados pelas equipe para executarem suas atividades. Por fim, concluiu-se que o maior desafio da organização é melhor avaliar e melhorar o seu processo de treinamento, dada a alta rotatividade de seu pessoal, para que a abordagem à população seja realizada da melhorar maneira possível.
levantamento bibliométrico do uso de imagens na prática da comunicação da governança pública em portais governamentais municipais
Authors: Martins Marcio do Nascimento , Vicentin Ivan Carlos
Published: September 2021

A comunicação do governo com seus cidadãos e o avanço das ferramentas de informação e contribui para que o Estado busque continuamente uma maior interação e proximidade com a população através de seus portais governamentais na internet. Dessa forma, a comunicação pública está diretamente associada à governança pública, representada pelo Estado executor de políticas públicas. E a manifestação de imagens nas plataformas governamentais (sites) é objeto de estudo da semiótica, uma vez que esta é quem organiza a produção e compressão do sentido da linguagem não verbal. O objetivo deste trabalho é realizar um levantamento bibliométrico de publicações nacionais e internacionais concernentes ao uso de imagens na prática da comunicação da governança pública nos portais governamentais dos municípios brasileiros e de outros países. A área de conhecimento do estudo é a Administração Pública (Business, Management and Accounting). A abordagem metodológica se utiliza da teoria bibliométrica e os procedimentos de coleta de dados ocorrem junto às bases Eric - Educational Resources Information Centre, Google Scholar, Science Direct, Scopus e Web of Science. Quanto aos seus objetivos, a pesquisa é definida como exploratório-descritiva, e definida como aplicada, quanto à sua natureza. As análises conduzidas demonstram que, com o emprego da totalidade dos termos de pesquisa, quais são Public Communication, Public Governance, Semiotics e Image(s), nenhum artigo foi encontrado nas cinco bases utilizadas. Embora mereça destaque o volume significativo de artigos que retornaram a partir da busca com emprego de frações dos termos de pesquisa, trata-se de produções científicas alheias ao objeto de pesquisa. Os resultados sugerem que esse déficit científico apontado no presente trabalho pode ser revelador de uma menor percepção dos cidadãos em relação ao conteúdo dos portais governamentais dos municípios. Ademais, face a amplitude de significação do campo de estudo da semiótica, os resultados também sugerem que não seria pelo aumento do número de bases de dados ou robustez da amostra, que a produção científica seja mais evidente em levantamentos bibliográficos dessa natureza.
O Ministério Público como ombudsman de políticas públicas
Authors: Santos Antonio Miguel Barros Tenório Varjão dos , Rita Luciana Peixoto Santa
Published: September 2021

Este artigo investiga o papel do Ministério Público na fiscalização de políticas públicas. O Ministério Público é instituição permanente, essencial à função jurisdicional do Estado, que exerce atualmente um grande protagonismo na sociedade brasileira. Esta realidade é relativamente recente, haja vista que, com a Constituição de 1988, o Ministério Público foi profundamente transformado. Antes de 1988, o órgão era responsável, basicamente, pela persecução criminal em juízo. Ao longo da década de 1980, o Parquet recebeu novas atribuições, entre as quais a de fiscalização de políticas pública, ganhando um design institucional único no mundo. O presente estudo tem como objetivo geral a descrição desta nova atribuição de controle de políticas públicas. Para atingi-lo, será descrita a trajetória de empoderamento, bem como as atribuições do Ministério Público na fiscalização de políticas públicas e os instrumentos de que a instituição dispõe para o cumprimento desta tarefa fiscalizatória, como a ação civil pública, o inquérito civil, o compromisso de ajustamento de conduta, a recomendação e a audiência pública. Como metodologia, foi empregada a análise de conteúdo de textos científicos, bem como de leis, propostas legislativas, autos de processos judiciais e de procedimentos extrajudiciais.
Reflexões sobre evasão na educação superior brasileira: possibilidades de prevenção e intervenção
Authors: Araujo Ana Carolina da Costa , Silva Thales Fabricio da Costa e , Pederneiras Marcleide Maria Macêdo
Published: September 2021

Nos últimos anos, houve significativa expansão do acesso ao ensino superior no Brasil, com a criação de universidades e cursos e com o aumento do número de vagas nas Instituições de Educação Superior. Paralelamente, também ocorreu aumento das taxas de evasão dos estudantes, fenômeno influenciado por diversos fatores acadêmicos e subjetivos. Este artigo tem o objetivo de apresentar uma revisão da literatura nacional sobre evasão no ensino superior brasileiro entre os anos de 2016 e 2020. A pesquisa documental foi realizada nas bases de dados SciELO e Banco de Teses e Dissertações da Capes. Os resultados encontrados nos 27 artigos publicados no Brasil foram analisados em cinco categorias: elementos que contribuem para a evasão dos discentes; evasão e adaptação ao contexto universitário; evasão, cursos noturnos e conciliação trabalho-estudo; evasão, políticas afirmativas de acesso e permanência e adoção do Sisu; estratégias utilizadas para prevenção e combate à evasão. Grande parte da literatura aponta a necessidade de as universidades repensarem as estratégias de permanência dos estudantes, tendo em vista que somente a expansão das vagas e a garantia do acesso aos cursos não concretizam o direito ao ensino superior. É importante que sejam criadas ações preventivas e de intervenção que facilitem a adaptação do discente ao ambiente universitário, especialmente nos primeiros anos dos cursos, momento em que os estudos apontaram maior percentual de abandono. Espera-se que as reflexões aqui geradas possam contribuir para o planejamento e para a realização de ações com vistas a reduzir as taxas de evasão e que mais estudos possam ser realizados com foco preventivo e interventivo.
Inovação na produção científica brasileira em gestão e negócios: mapeamento bibliométrico nas bases Web of Science e Scopus
Authors: Menezes Edivaldo Rabelo de , Fernandes Antônia Rafaela Pamola Mota , Rego Filho Francisco Souza
Published: September 2021

A inovação é amplamente difundida como um mecanismo capaz de promover o desenvolvimento da sociedade através da criação de novos aparatos tecnológicos e melhoria de técnicas utilizadas na atualidade. No Brasil, o tema ganhou marco legal com a publicação da Lei 10.973, de 2 de dezembro de 2004 (Lei da Inovação), e a partir daí mecanismos para uma série de investimentos públicos e privados. Nessa perspectiva, o presente estudo objetivou avaliar qual o impacto na produção cientifica brasileira sobre inovação e negócios acerca da inovação após a implementação da referida lei. Utilizou-se, portanto, um estudo bibliométrico com a string de busca “TS = (Innovation*) AND CU = BRA?Il*” em um espaço temporal de 2005 até 2019 nas bases de dados da Web of Science e Scopus. O estudo evidenciou um crescimento das pesquisas sobre a temática, partindo números entre 2 e 7 no ano de 2005 para números como 230 e 288 em 2018, na Scopus e Web of Science, respectivamente. Entre às áreas de publicação, se evidenciou que as áreas de gestão e negócios concentram a maior parcela de publicações, sendo a maioria publicado em formato de artigo nas duas plataformas. A instituição que mais se destacou no estudo foi a Universidade de São Paulo (USP), sendo a que mais publicou em ambos as bases de dados. Observou-se também que as revistas que mais publicam sobre o tema são a Espacios e a Geintec, sendo a professora do Centro Universitário UNIFBV/Wyden Eliana Andrea Severo e o professor da USP Felipe Mendes Borini os pesquisadores brasileiros que mais se destacam na área, com 21 e 15 publicações, na Scopus e Web of Science, respectivamente. Porém, entre os estudos mais citados pelos pesquisadores brasileiros, ainda se evidenciou uma predominância do uso de referências internacionais, sendo que as publicações mais citadas pelos estudos brasileiros em ambas as bases são de autoria internacional, mesmo havendo colaboração brasileira em casos específicos. O estudo, portanto, evidenciou o crescimento do interesse sobre a temática após a promulgação da Lei da Inovação, e que possui instituições que produzem bastante sobre a temática, mas ainda evidenciou a necessidade dos pesquisadores brasileiros de recorrem a fontes internacionais para embasar seus estudos.

Estudo comparativo: método empírico do DNIT e mecanístico-empírico (Medina) no dimensionamento de pavimentos flexíveis
Authors: Silva Larissa Macário da , Santos Rafaella Oliveira Guimarães
Published: September 2021

O presente estudo de pesquisa fez uso do novo programa de dimensionamento de pavimentos flexíveis o Método de Dimensionamento Nacional – Medina programa totalmente Brasileiro, desenvolvido por meio de parcerias entre entidades brasileiras. Como objetivo realizou-se uma análise comparativa entre os métodos de dimensionamento de pavimentos, o empírico atualmente empregado pelo Departamento Nacional de Infraestrutura e Transportes (DNIT) e o método mecanístico-empírico de Dimensionamento Nacional de Pavimentos (MEDINA), a fim de elucidar o uso do método mecanístico-empírico. Com a finalidade de comparar o dimensionamento das camadas de base e sub-base de pavimentos flexíveis, por meio dos diferentes métodos, sendo adotado o método empírico que tem como fundamento os dados de CBR, empregado pelo DNIT e o mecanístico-emprírico (Medina) com base em conceitos da teoria da elasticidade. Para cálculo das espessuras das camadas do pavimento flexível, foram propostos dois volumes de tráfego diferentes. Os dados dos materiais que foram utilizados nas camadas de base e sub-base foram obtidos a partir de estudos bibliográficos prévios. Na sequência foi realizado o dimensionamento do pavimento com os dois métodos propostos. Dentre os resultados obtidos, observa-se que Medina permite maiores análises e variações de materiais de revestimento, com base nas propriedades dos materiais. Para as possibilidades analisadas, destaca-se o tipo de material utilizado na camada do revestimento influenciando consideravelmente em sua espessura, fator relacionado ao módulo resiliente desses materiais, ou seja, para os casos propostos a espessura da camada de revestimento foi menor quanto maior foi o MR do revestimento adotado. O resultado que mais se destacou foi no caso 2.2 em que o revestimento foi de concretos betuminoso com 7,5cm de espessura no método empírico e pelo método mecanístico-empírico concreto asfáltico de classe 4 com 9,4cm manifestou melhores resultados para as camadas de revestimento, atendendo aos padrões de dimensionamento do programa. Ressalta-se que o dimensionamento efetuado pelo novo método colabora com a viabilidade a longo prazo e o pavimento tende a alcançar seu tempo de vida útil com maior segurança e economicidade, comparado ao método empírico.

Authors: Borchert Oliver , Lee Kyehwan , Sriram Kotikalapudi , Montgomery Doug , Gleichmann Patrick , Adalier Mehmet
Published: September 2021

In this paper, we first describe the problem space. Following that, we describe the design and implementation of the NIST reference implementation for RPKI-based route origin validation (BGP-OV) and BGPsec path validation (BGP-PV) within a BGP router. The system we developed is called BGP Secure Routing Extension (BGP-SRx). We describe the system design, explain the design choices, communications between all components, and present the performance measurements obtained during the implementation stages. This paper is organized so that it first explains the high-level system design with a brief explanation of all components and how they interact. We will explain why we chose this design and provide a discussion of its benefits as well as shortcomings. Furthermore, we show which open-source components we chose and how we extended them for this project. The BGP-SRx implementation is a reference implementation for RPKI-OV with all its router side components as specified in RFC 6811, RFC 6810, and RFC 8210 as well as for BGPsec path validation as specified in RFC 8205 and RFC 8608. The implementation allowed early identification of issues while the specifications were still under development, hence provided important feedback to the development of the different IETF RFCs.
Assessing the quality of as-received 4340 steel for the production of NIST Charpy reference specimens
Authors: Lucon Enrico , Martin May
Published: September 2021

The Charpy Machine Verification Program at NIST in Boulder uses heat-treated 4340 steel for the production of indirect verification Charpy specimens at low- and high-energy level. Recently, a batch of steel purchased for the program turned out to be unacceptably inhomogeneous, causing several NIST Contractors to produce specimen lots that did not fulfil our variability requirements, despite repeated attempts at modifying the heat-treatment process. The whole batch of steel had to be eventually scraped. In order to avoid such an occurrence in the future and develop an investigation procedure that can detect variability issues in the acceptance phase of newly purchased batches of 4340 steel, we have performed the following investigations and measurements on samples from good and bad heats: hardness measurements (Rockwell C and Vickers), instrumented Charpy tests, optical investigations, and texture analyses (including grain size measurements). Of all the parameters considered, we found that grain size can clearly differentiate between acceptable (30 m 40 m) and unacceptable (60 m 70 m) heats, and should therefore become the basis of future heat quality assessments. In support, hardness measurements can also be performed, while Charpy tests are not recommended in view of their relative experimental and economic burden.

Short-medium chain saturated triglyceride is a low viscosity and degradable liquid dielectric material, which has potential applications in the field of transformer internal insulation. In this paper, the molecular properties of short-medium chain saturated triglycerides under the action of electric field are studied by using density functional theory and time-dependent density functional theory. The results show that the molecular bond length is obviously dependent on the electric field intensity, which is consistent with the shift of the infrared wave number peak. Under the same electric field, with the increase of the length of carbon chain, the dipole moment and polarity of the molecule increase correspondingly. When the electric field intensity is 109 V/m, the energy of the highest occupied molecular orbital of tricaprylin and tricaprin increases obviously, and the ionization potential decreases sharply. The difference in excitation characteristic between molecules is small, and the decrease of excitation energy is much smaller than that of ionization potential under the same electric field. The results are helpful in improving the understanding of discharge mechanism in ester dielectric, and provide the theoretical support for the performance improvement of natural ester insulating oil.
Novel ACE2 protein interactions relevant to COVID-19 predicted by evolutionary rate correlations

Angiotensin-converting enzyme 2 (ACE2) is the cell receptor that the coronavirus SARS-CoV-2 binds to and uses to enter and infect human cells. COVID-19, the pandemic disease caused by the coronavirus, involves diverse pathologies beyond those of a respiratory disease, including micro-thrombosis (micro-clotting), cytokine storms, and inflammatory responses affecting many organ systems. Longer-term chronic illness can persist for many months, often well after the pathogen is no longer detected. A better understanding of the proteins that ACE2 interacts with can reveal information relevant to these disease manifestations and possible avenues for treatment. We have undertaken an approach to predict candidate ACE2 interacting proteins which uses evolutionary inference to identify a set of mammalian proteins that “coevolve” with ACE2. The approach, called evolutionary rate correlation (ERC), detects proteins that show highly correlated evolutionary rates during mammalian evolution. Such proteins are candidates for biological interactions with the ACE2 receptor. The approach has uncovered a number of key ACE2 protein interactions of potential relevance to COVID-19 pathologies. Some proteins have previously been reported to be associated with severe COVID-19, but are not currently known to interact with ACE2, while additional predicted novel ACE2 interactors are of potential relevance to the disease. Using reciprocal rankings of protein ERCs, we have identified strongly interconnected ACE2 associated protein networks relevant to COVID-19 pathologies. ACE2 has clear connections to coagulation pathway proteins, such as Coagulation Factor V and fibrinogen components FGA, FGB, and FGG, the latter possibly mediated through ACE2 connections to Clusterin (which clears misfolded extracellular proteins) and GPR141 (whose functions are relatively unknown). ACE2 also connects to proteins involved in cytokine signaling and immune response (e.g. XCR1, IFNAR2 and TLR8), and to Androgen Receptor (AR). The ERC prescreening approach has elucidated possible functions for relatively uncharacterized proteins and possible new functions for well-characterized ones. Suggestions are made for the validation of ERC-predicted ACE2 protein interactions. We propose that ACE2 has novel protein interactions that are disrupted during SARS-CoV-2 infection, contributing to the spectrum of COVID-19 pathologies.
Цифровая флуоресцентная микроскопия: новый аналитический инструмент для изучения микроорганизмов, "Природа"

За последние двадцать лет флуоресцентная микроскопия трансформировалась из субъективного визуального метода в объективный аналитический подход — цифровую флуоресцентную микроскопию (ЦФМ). Произошло это благодаря совокупности инноваций, связанных с модернизацией микроскопов, использованием компьютерной обработки и анализа цифровых изображений, а также применением новых флуорофоров и методов их внедрения в клетки микроорганизмов. ЦФМ открыла принципиально новые возможности для изучения микроорганизмов, которые позволяют получать уникальную информацию о локализации и динамике внутриклеточных процессов при изучении единичных клеток микроорганизмов на субклеточном уровне.
Реологические процессы в земной коре, "Природа"
Authors: Ермолаев Г.С.

Реологические свойства вещественного состава определяют геодинамическое взаимоотношение геологических образований и отражают послеальпийское тектоническое течение горных масс. Оно проявляется в виде неоднородностей, таких как структурные и бесструктурные образования. Материки и океаны, платформы и подвижные пояса, рудные и безрудные участки тесно связаны с современным рельефом, подчеркивая геодинамическую взаимосвязь между формой и содержанием, пространством и временем. Движущей силой в реологических преобразованиях служит термодинамическая пластическая геомасса, которая зарождается в недрах Земли. Взаимодействие подкоровых (пластичных) и коровых (жестких) образований приводит к расслаиванию последних и перемещению их термодинамической, пластической геомассой на значительные расстояния — как по вертикали, так и по горизонтали (с преимуществом горизонтальной компоненты). Территория Центральной Азии характеризуется преобладанием выровненного рельефа над возвышенным. Установлена общая реологическая закономерность в размещении геологических объектов, в том числе рудных. Так, наиболее жесткие образования слагают преимущественно возвышенные участки рельефа, а пластичные коррелируют с выровненной его частью. Рудный минеральный комплекс, характеризуясь вязкоупругими деформационными свойствами, занимает промежуточное положение. Рудные районы, содержащие крупные промышленные объекты, такие как Алмалыкский и Кызылкумский, располагаются в торцовых сочленениях структур преимущественно домезозойского возраста (Южный и Центральный Тянь-Шань) с мезозойско-кайнозойским и четвертичным комплексами. Это может свидетельствовать о разрыве рудоносных структур в местах наибольшего скопления минерального вещества, что подтверждается широким развитием разрывных нарушений, якобы «контролирующих» размещение рудных полей и месторождений.
КАК АНГЛИЙСКИЕ КРЕСТЬЯНЕ ПЕРЕДАВАЛИ ИМУЩЕСТВО? ОБЫЧАЙ И МАНОРИАЛЬНАЯ ПРАКТИКА, "Средние века"
Authors: Винокурова М.В.
Published: September 2021

В статье (на основе изучения манориальной документации по преимуществу XIII–XIV вв.) обобщаются формы передачи имущества в среде средневекового английского крестьянства через манориальную курию. Показано, что, поскольку вилланы и копигольдеры как зависимые слои населения, не могли составлять завещаний, в повседневной жизни они были вынуждены прибегать к особым формам «наследования» движимого и – особенно – недвижимого имущества. В частности, согласно обычаю, практиковались так называемые передачи земли (через «руки лорда» в курии манора) с письменной фиксацией условий держания в договоре с последующим принесением держателем феодальной присяги лорду и выплатой им вступного файна. К числу таковых относились: «сдача» земли в курии по истечении сроков копий или после смерти держателя; оформление вдовьей доли; фиксация имущества в случаях возникающей срочной необходимости (болезнь, долговые обязательства, голод и пр.); передачи «из милосердия» чужим лицам; передачи, связанные с изменением статуса земли, и некоторые другие. Особенное внимание уделено так называемым устным передачам имущества на смертном одре в присутствии свидетелей с последующей их письменной фиксацией в манориальной курии.

Aims: The objective of this study was to investigate on microbial related food safety issues and microorganisms associated with the production of Sri Lankan traditional seafood Jaadi.

Place and Duration of Study: Food Technology Section, Industrial Technology Institute, Colombo, Sri Lanka, between December 2013 to April 2016.

Methodology: Seven Jaadi processing centers along the Southern and Western coastal belt of Sri Lanka were evaluated for its compliance to food safety, in terms of environment, processing techniques, hygiene and sanitation, physiochemical and microbiological quality of the final product. 

Samples drawn from all sites were analyzed for its water activity, salt content, pH and microbiological quality.  Microorganisms associated with Jaadi production were isolated in selective media, followed by phenotypical, biochemical and molecular biological characterization.

Results: The pH, water activity and salt content of Jaadi samples ranged between 3.60-5.85, 0.73-0.82 and 24.82-40.47%, respectively. Thirteen bacterial strains and one fungal strain detected were strains found to be responsible for human pathogenesis and food spoilage. These include,  Bacillus cereus strain I (MN726935.1), Bacillus cereus strain II (MN901259.1), Bacillus haikouensis strain I (MN901262.1), Bacillus haikouensis strain II (MN726976.1), Bacillus licheniformis (MN726987.1), Acinetobacter baumannii (MN901499.1), Bacillus pumilus strain I (MN901264.1), Bacillus pumilus  strain II (MN901263.1), Bacillus paralicheniformis (MN901167.1), Bacillus thuringiensis strain I (MN901165.1), Bacillus thuringiensis strain II (MN901257.1), Bacillus cereus (MN901161.1), Staphylococcus saprophyticus (MN901156.1) and Trichoderma longibrachiatum (MN907169.1).  Presence of such organisms clearly proclaims the poor hygienic practices and risks related to food safety in this traditional processing technology.

Conclusion: Jaadi processing facilities of Southern and Western coastal belt of Sri Lanka needs scientific and technical knowledge to upgrade their processing in order to assure food safety and product quality.
