Human Gut Microbiome as an Indicator of Human Health
Authors: Ivanova Anasnasiia , Yalovenko Olena , Dugan Alexey
Published: December 2021

The undeniable achievement in the study of the gut microbiome as an association of different microorganisms, including viruses, that colonize various organs and systems of the body, is the establishment of the fact that some diseases that were consmicrobiotaidered as non-infectious can also be transmitted through microorganisms. This resulted in the gut microbiome being called a forgotten organ that could serve as an additional and kind of missing link for a more objective and better diagnosis and treatment of many diseases that were not considered infectious. The rapid development of gut microbiome research in recent years not only is connected with better understanding of the functioning of the microbiome by the scientific community, but also inseparable from the strategic support of each country. Global investment in researches, related to the human microbiome, has exceeded $1.7 billion over the past decade. These researches contribute to the development of new diagnostic methods and therapeutic interventions. Our review is dedicated to the analysis of the possibilities of application of the human gut microbiome for the diagnosis of diseases, and the role of the intestines in the provocation and causing of certain diseases. Significant differences in the composition and diversity of the human microbiome are shown depending on geographical location and the change of socio-economic formations towards a gradual decrease in the diversity of the gut microbiome due to three stages of human population’s existence: food production, agriculture and industrial urban life. We analyze the influence of dietary patterns, various diseases (including malignant neoplasms) and viral infections (in particular, coronavirus) on the gut microbiome. And vice versa – the influence of the gut microbiome on the drugs effect and their metabolism, which affects the host's immune response and course of the disease.

Published: December 2021

Os dois últimos anos trouxeram inúmeros desafios para a sociedade, especialmente devido à Pandemia da COVID-19, que mudou as vidas de todas as pessoas (UNESCO, 2020). Nesse período, muitas tiveram que desenvolver seu trabalho em casa, no formato de home office, buscando atender aos protocolos sanitários de saúde acerca da pandemia. Especificamente para estudantes e professores, muitos tiveram que desenvolver as suas atividades de pesquisa e aulas de forma remota, que associadas às tarefas domésticas, causaram um desgaste emocional na maioria deles (Langin, 2021). Há pesquisas, inclusive, que afirmam que a pandemia ainda afetará a vida das pessoas ainda por bastante tempo (Gruber, et al., 2021). No Brasil, o ano de 2020 também foi marcado pelo problema da propagação de desinformação (mais conhecida como fake news) no intuito de desacreditar a ciência quanto a eficácia das vacinas contra COVID-19 (Assis, Komesu & Pollet, 2021) e da importância da necessidade de manter o distanciamento social e uso de máscara para evitar o contágio e propagação da doença. Infelizmente, de acordo com o Consórcio de Veículos de Imprensa do Brasil a partir de dados de Secretarias Estaduais de Saúde , o país é um dos mais afetados pelo novo coronavírus, com 618.484 mortes registradas até 26 de dezembro de 2021. No entanto, semelhante ao ano de 2020, e buscando se manter atualizada na ciência internacional, dentre os inúmeros artigos recebidos ao longo do ano, a Revista Brasileira de Educação do Campo (RBEC) publicou outras pesquisas sobre a Pandemia da COVID-19, a partir de diferentes contextos e perspectivas internacionais, algo fundamental para elevar a qualidade da discussão no que concerne à formação docente em escolas e universidades, tanto do meio urbano quanto do campo. Além do fluxo contínuo, publicado regularmente no formato de Publicação Contínua desde 2019, a RBEC publicou importantes dossiês no ano de 2021 que abordam desde o ensino desenvolvido no período pandêmico, a pesquisas referentes à Educação do Campo na América Latina, egressos da Educação do Campo no Brasil, psicologia rural, além de estudos sobre a arte no campo. São estudos desenvolvidos em diferentes contextos sociais, que ajudam a ampliar um pouco mais o campo de investigação acerca da Educação do Campo no Brasil e em outros países. Desejamos a todos e a todas boas leituras e um próspero ano de 2022!
The Adoption of Found Child According to Islamic Law and Law No. 3 of 2006 on Religious Courts in the Perspective of Maqasid Al-Shari'ah
Authors: Muniroh Siti , Nasution Khoiruddin
Published: December 2021

Islam is a religion that regulates everything in the life of Muslims. No exception in the case of adoption, the jurisdiction of the court up to the adoption of a minor. in the case of child adoption. Today, Islam applies limitations in some matters, such as the prohibition of lineage, the establishment of non-mahram relationships to the issue of inheritance and guardianship. In addition to that field, there is the authority of the judge in the Religious Court to be ijtihad to determine the best decision for the child of the findings as the extent of its authority is based on Law No. 3 of 2006 on Religious Justice. The purpose of this study is to analyze how the legal impact on the adoption status of the findings based on the rationale maqasidus syar'i and its relevance to the development of Islamic law. Research methods use the study of literature through its sources of reference through primary law, both derived from religious sources and from positive legal sources that apply in Indonesia. In addition, the researcher used jurisprudence from the relevant judicial decisions used.The results of this research are (1) through the approach of maqasid al shari'ah doruriyah that children (including children of discovery) must be protected their rights, both their right to life (an nafs) and their intellect (al aql), the right of lineage, religion, as well as paying attention to his rights, including his right to obtain the obligatory will/right of inheritance from the parents who raised him (al maal), (2) The legal impact is, the child is found as a person, he is an orphan so the religious treatment is the same as an orphan. While the adopted child then the legal status can be assessed through recognition by the adoptive parents such as the child of guardianship, then the adopted child has the right to be guarded by his adoptive parents due to the absence of a lineage guardian. (3) While the relevance to the development of Islamic law is that in maintenance (other than the issue of lineage and inheritance), then the child has the same protection and education status of both adoptive parents. There is a need for efforts from various related parties to prioritize the benefits to protect from unwanted things and save the lives of children.

Прямой метод определения космологических расстояний использует наблюдения
на этапе роста светимости сверхмощных сверхновых, чья кривая блеска может
быть объяснена взаимодействием ударной волны с плотным околозвездным веществом. В основе метода лежит предположение о сферической симметрии образующегося в системе плотного тонкого слоя, который в неодномерной модели может
быть неустойчивым. В данной работе рассматривается моделирование сверхновой
SN2009ip, хорошо показавшей себя для прямого метода, с помощью радиационно-гидродинамического кода FRONT. Показано, что текущая реализация кода корректно воспроизводит в упрощенной модели болометрическую кривую блеска и
динамику движения плотного слоя. Также продемонстрировано, что в рассматриваемой постановке слой сохраняет сферическую симметрию по крайней мере на
этапе роста кривой блеска.

Evaluation of phosphate sorption capacity and external phosphorus requirement of some agricultural soils of the southwestern Ethiopian highlands
Authors: Dinssa Berhanu , Elias Eyasu
Published: December 2021

One of the most soil fertility management problems for crop production on acidic soils of the Ethiopian highlands is phosphorus fixation. The research was executed to assess the P-sorption capacity and to determine the external P requirement of different acidic soils in the Southwestern highlands of Ethiopia. Phosphorus sorption capacity (Kf) and its relation with selected soil characteristics were assessed for some major agricultural soils in the Ethiopian highlands to answer the questions, ‘What are the amount of P-sorption capacity and external P requirement of Nitisols, Luvisols, Alisols, and Andosols in Ethiopia?’. Twelve surface soil samples (at depth of 0-30 cm) were gathered and the P-sorption capacity was estimated. Phosphorus-sorption data were obtained by equilibrating 1 g of the 12 soil samples with 25 ml of KH2PO4 in 0.01 M CaCl2, having 0, 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, and 330 mg P L-1 for 24 hours. The data were adjusted to the Freundlich adsorption model and the relationship among P-sorption and soil characteristics was established by correlation analysis.  Clay content and exchangeable acidity, organic matter, Al2O3, and Fe2O3 oxides have affected phosphorus-sorption at a significance level of (P < 0.05).  Alisols had the highest Kf value (413 mg kg-1) but Nitisols had the lowest Kf (280 mg kg-1). The external phosphorus fertilizer requirement of the soils was in the order of 25, 30, 32, and 26 mg P kg-1 for Nitisols, Luvisols, Alisols, and Andosols sequentially. The Kf varies among different soil types of the study area. The magnitude of the soil’s Kf was affected by the pH of the soil, soil OM content, and oxides of Fe and Al. Therefore, knowledge of the soils’ P retention capacity is highly crucial to determine the correct rate of P fertilizer for crop production.

Published: December 2021

Sustainability of the Cocos Nucifera’s High Production Block (HPB) in Tanjung Jabung Timur Regency. Jambi Province is threatened by falling coconut prices. It influences the farmer's interest to do replanting and use certified seeds produced by HPB. The evaluation of HPB not only base on the economic dimension, but it should also accommodate broader dimensions. The purpose of the study is to analyze the sustainability of HPB. Primary data were obtained from observations, focus group discussions, and interviews with 20 respondents of HPB plantation owners, while secondary data were obtained from Statistics office and government agencies. The existing condition of the HPB was analyzed by comparing it with the standard of HPB and selected parent trees issued by the Indonesian Ministry of Agriculture. Analyzing of HPB sustainability used a modified Multi-Dimensional Scaling (MDS) Rapfish for coconut, then called Rap-ProBlock (The Rapid Appraisal of the Status of Cocos Nucifera's High Producing Block). The results showed that the sustainability indexes were sufficient and good for the social (64.18) and ecological (85.69) dimensions, the economic and technological dimensions had less sustainability (34.76 and 32.58), and the legal/institutional dimension was poor (9. 16). On a multi-dimensional basis, HPB sustainability was lacked (40.30). The recommended policies based on this research results among others are i.e. issuing the Local Regulation on Cocos Nucifera, establishing the Warehouse Receipt System which guarantees farmers a fair price, and, involving village enterprise to build coconut business units.

The study used a quasi-experimental pretest, posttest non-equivalent group design. two intact classes were selected in Chiro district of Oromia Regional State, Ethiopia. The first class belonged to the treatment group where TM contents are integrated through 5E’s learning cycle with the topic Microorganism and Disease and the second was assigned as comparison group learning the same biology unit on Microorganisms and Disease using the usual approach. Biological Attitude Questionnaires (BAQ) was administered for both groups as pre- and post-tests. The findings showed that the integration of TM with the school biology enhanced students’ attitude towards biology as compared with teaching the topics without integration.
Seismic Tomography of Kamchatkan Volcanoes
Authors: Koulakov I.Yu.
Published: December 2021

—The Kamchatka Peninsula is one of the most tectonically active regions in the world, where intensive and diverse modern volcanic activity takes place. In the recent decade, substantial progress in the investigation of deep structures beneath Kamchatka has been achieved owing to numerous tomography studies based on seismological data provided by permanent stations and temporary networks deployed in some key areas. The goal of this review is summarizing and systematizing dozens of separate multiscale geophysical studies in Kamchatka and constructing an integral model of volcano-feeding systems. An important part of this review contains the description of results of various seismic studies related to the Klyuchevskoy group volcanoes, which can now be considered one of the best studied volcanic areas in the world. The results of the regional-scale seismic tomography reveal the existence of the Pacific slab window, which determines the particular activity of the Klyuchevskoy group volcanoes. Middle-scale tomography studies have found traces of an ascending hot mantle flow that passes through the slab window, reaches the bottom of the crust below Shiveluch Volcano, and then propagates laterally toward the Klyuchevskoy group. Seismic models of the entire crust in the area of the Klyuchevskoy group were used to identify different mechanisms of magmatic feeding of three most active volcanoes: Klyuchevskoy, Bezymianny, and Tolbachik. The data of local networks deployed on several volcanoes of Kamchatka were used to image the magma sources in the upper crust, which are directly responsible for the current eruption activity. The comparison of the results for the Kamchatka volcanoes with tomography models of several other volcanoes of the world allowed determining some common features and differences in feeding active magmatic systems.
A thermodynamic origin for the Cohen-Kaplan-Nelson bound
Authors: Ramakrishna Satish
Published: December 2021

The Cohen-Kaplan-Nelson bound is imposed on the grounds of logical consistency (with classical General Relativity) upon local quantum field theories. This paper puts the bound into the context of a thermodynamic principle applicable to a field with a particular equation of state in an expanding universe. This is achieved without overtly appealing to either a decreasing density of states or a minimum coupling requirement, though they might still be consistent with the results described. The paper establishes that the holographic principle applied to cosmology is consistent with minimizing the free energy of the universe in the canonical ensemble, upon the assumption that the ultraviolet cutoff is a function of the causal horizon scale.

Authors: Feng Qiu-Xia , Tang Bo , Liu Xi-Sheng
Published: December 2021

Background: The study aimed to evaluate the diagnostic performance of machine learning-based CT radiomics models for predicting the recurrence and metastasis of gastrointestinal stromal tumors (GISTs) preoperatively.Methods: A total of 382 patients with histopathological confirmed GISTs were retrospectively included. According to postoperative follow-up, patients were classified into non-recurrence and metastasis group (NRM) and recurrence or metastasis group (RM). Radiomics features were extracted from arterial and portal venous phase CT images. Four feature selection methods and ten machine learning techniques were used to train predicting models on training cohort with internal validation by 10-fold cross-validation. F1 score was used to evaluate the performance of the classiﬁcation model. The best model of two phase were stacked to build an ensemble model. The area under the curve (AUC), recall, precision, accuracy, and F1 score were used to evaluate the performance of the models and compare with clinical criteria based on diameter.Results: Eighty machine learning models in two phases were built and the ensemble model was integrated by analysis of variance and Naive Bayes (ANOVA_NB) model in arterial phase which selected only 5 features provided the highest F1 Score of 0.560 and Kruskal Wallis and Adaptive Boosting (KW_ AdaBoost) model in venous phase which selected only 4 features provided the highest F1 Score of 0.500. The AUC of the generated ensemble model and the clinical criteria showed no difference (0.866 vs 0.857; DeLong Test, P = 0.865). But the ensemble model had higher accuracy (0.961), recall (0.826), precision (0.905), F1 Score (0.864), and the area under the Precision-Recall curve (0.774; 95%CI, 0.552 - 0.917), compared with clinical criteria, of which, the accuracy was 0.942, recall was 0.367, precision was 0.478, the F1 Score was 0.415 and the area under the Precision-Recall curve was 0.354(95%CI, 0.552 - 0.917).Conclusions: Our findings highlight the potential of machine learning techniques based on CT radiomics in the prediction of recurrence and metastasis of GISTs preoperatively.
Experiments And Simulations of Thermometric Lateral Flow Immunoassay For Point-of-Care Testing
Authors: Azuma Terumitsu , Hui Yuen Yung , Chen Oliver Y. , Wang Yuh-Lin , Chang Huan-Cheng
Published: December 2021

Temperature sensing is a promising method of enhancing the detection sensitivity of lateral flow immunoassay for point-of-care testing. A temperature increase of more than 100 °C can be readily achieved by photoexcitation of reporters like gold nanoparticles (GNPs) or colored latex beads (CLBs) on the strips with a laser power below 100 mW. Despite its promise, processes involved in the photothermal detection have not yet been well-characterized. Here, we provide a fundamental understanding of this thermometric assay by combining experiments and simulations using non-fluorescent CLBs as the reporters deposited on nitrocellulose membrane. By measuring the dependence of temperature rises on the number density of membrane-bound CLBs, we determined a 1.5-fold enhancement of the light absorption at 520 nm by the beads (diameter of 0.4 μm). The enhancement, however, was compromised by a 5-fold reduction of the incident laser power due to multiple scattering of the light in this highly porous medium. The limit of detection was measured to be 1 × 105 particles/mm2. In line with previous studies using GNPs as the reporters, the CLB-based thermometric assay provides a 10× higher sensitivity than color visualization, as demonstrated with the immunoassay for nucleocapsid proteins of the SARS-CoV-2 virus.

Published: December 2021

The emergence of the highly-transmissible B.1.1.529 Omicron variant of Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is concerning for antibody countermeasure efficacy because of the number of mutations in the spike protein. Here, we tested a panel of anti-receptor binding domain monoclonal antibodies (mAbs) corresponding to those in clinical use by Vir Biotechnology (S309, the parent mAb of VIR-7831 [Sotrovimab]), AstraZeneca (COV2-2196 and COV2-2130, the parent mAbs of AZD8895 and AZD1061), Regeneron (REGN10933 and REGN10987), Lilly (LY-CoV555 and LY-CoV016), and Celltrion (CT-P59) for their ability to neutralize an infectious B.1.1.529 Omicron isolate. Several mAbs (LY-CoV555, LY-CoV016, REGN10933, REGN10987, and CT-P59) completely lost neutralizing activity against B.1.1.529 virus in both Vero-TMPRSS2 and Vero-hACE2-TMPRSS2 cells, whereas others were reduced (COV2-2196 and COV2-2130 combination, ~12-fold decrease) or minimally affected (S309). Our results suggest that several, but not all, of the antibodies in clinical use may lose efficacy against the B.1.1.529 Omicron variant.

Published: December 2021

This study was designed to compare the postoperative outcomes of bicanalicular intubation using different diameters of silicone tubes to treat post-saccal nasolacrimal duct obstruction. A total of 130 patients diagnosed with post-saccal obstruction who underwent endoscopic-assisted silicone tube intubation were included in the study. The patients were divided into two groups; those intubated with a 1.5-mm large diameter tube (Group LD) and those with a 1.0-mm normal diameter tube (Group ND). The patency rates of the two groups at one year after tube removal were compared using the Kaplan–Meier's curve and Restricted mean survival time (RMST) method with τ = 365 days. Results showed that the recurrence rate after tube removal was significantly lower in the LD group compared to the ND group (p = 0.001). The patency rates at one year after removal in the LD and ND group were 0.857 (0.754-0.919) and 0.739 (0.617-0.828), respectively. When comparing the patency rates by the RMST method at τ = 365 days, the RMST difference, RMST ratio, and RMTL ratio were significantly higher in the LD group at p = 0.045, 0.052, and 0.046, respectively.
Hypernet Model of Media Communication: new qualities of risks for children
Authors: Polyanina A. K.
Published: December 2021

The technologically determined hyperbolic growth of communicative connectivity and the imperfection of administrative mechanisms of control over this process lead to an emergence of new phenomena and new risks, including risks in relation to the most vulnerable social group – children. The article proposes a new approach to describing the nature of the risks of the media space in relation to the health and development of children. Minimization of these risks is defined by the author as the goal of ensuring the information security of children. New qualities of risks are described on the basis of a hypernet model of media communication and developed on the basis of the hypernetwork brain theory. The author specifies the properties of hypernet education and their riskiness, mediated by the network morphology of connections, which implies the impossibility or ineffectiveness of the application of customary management practices. The vulnerability of the child group to these risks stem from the psychological immaturity. The importance of the phenomenalization of “media” and “information” is noted for the purposes of information policy and security – media security. The article reveals the tendencies of the media hypernetwork that increase the risks, especially the growth in the speed and volume of information transfer provided by technologies, which excludes the action of the well-known mechanisms for regulating the circulation of information and filtering content.
Ecology of Communication: the toxicity factors in media
Authors: Glushchenko O. A. , Grishanin N. V. , Kirillina N. V.
Published: December 2021

The paper raises the problem of media ecology. The concept of media ecology is considered from the standpoint of post-nonclassical rationality: the object of research is viewed as a system that unifies communicants, their communities and the information environment within the framework of ongoing interactions, which, in turn, affect all elements of the ecosystem. The authors analyze socio-cultural changes caused by media influence and give the interpretation of the manifestations of media toxicity through five components of communication (toxicity factors): (1) subject; (2) sign code; (3) content; (4) method and (5) discourse background. The experimental base of the research is represented by a lexical-semantic analysis of materials from print and electronic media and students' essays (n>300), an associative experiment conducted with students of the direction of training “Advertising and public relations” (Moscow and St. Petersburg, n> 200). At the end the authors share the experience of holding a scientific conference dedicated to the discussed problem as an optimal format for involving students in the problems of the ecology of media communication.

The relationship between dividend policy and bank growth
Authors: Fawzi Shubita Mohammad
Published: December 2021

The purpose of this study is to investigate the association between bank growth and the retained earnings amount for Jordanian banks between 2010 and 2020. The method to be used is regression models. Bank growth is measured using the change in total assets; income retention is measured by subtracting dividends from earnings per share and by deducting dividend per share from the operating cash flow on the accrual basis and cash basis. In addition, another specification will be used to the association between the growth of a bank’s total assets and income retention using the percentage change in the growth of a bank’s total assets and income retention on the accrual and cash basis. The findings of pooled OLS regression models and random effect models show that there is no relationship between income retention using the accrual basis and the bank total assets growth (Adj-R2 was –005). There is a significant relationship between income retention using the cash basis and the bank growth in total assets (Adj-R2 was 14%). There is no significant association between change in income retention using the cash basis and the bank growth in total assets, and bank size affects the relationship between income retention and bank growth in total assets.

Authors: Niyama Beatriz Mendes , Cabral Guilherme Perez
Published: December 2021

O artigo tem como objetivo analisar o processo de construção normativa, no cenário de Guerra Fria, do Protocolo de Buenos Aires (1967) – que reforma a Carta da Organização dos Estados Americanos (OEA) – particularmente a introdução da noção de educação para democracia. Partindo da relação entre governos autoritários e a Organização Interamericana, a pesquisa se concentrou na atuação da Ditadura Civil-militar brasileira neste processo. Foi adotado método histórico documental, a partir de fontes primárias, como relatório, atas de reuniões e correspondências da Organização e dos representantes dos Estados, identificados a partir da sistematização dos arquivos físicos do Centro de Pesquisa e Documentação de História Contemporânea do Brasil (FGV-RJ), complementado pela revisão bibliográfica crítica da matéria.  Os resultados atingidos permitem a conclusão de que a conexão entre educação e democracia, inserida na Carta da OEA por meio da atuação de governos autoritários, atende à perspectiva econômica liberal, constituindo, em última análise, uma educação para o capitalismo liberal, na luta anticomunista.  Conclui-se que a inserção da democracia como objetivo educacional representa, do ponto de vista político-pedagógico,  uma promessa vazia.

Published: December 2021

A soberania é um dos elementos essenciais para a constituição do Estado moderno. Nesta condição, representa as exigências efetivas de governabilidade do domínio interno e da independência externa. Portanto, a soberania é uma das condições fundamentais para o reconhecimento desta grande estrutura organizada e centralizada que se constitui como uma unidade política independente. Desse modo, a soberania atribui ao Estado um poder extraordinário. Isto tanto para produzir um processo de autonomia quanto para gerar submissão e obediência. Então, o presente texto se preocupa em analisar, a partir das contribuições teóricas de Michel Foucault, Giorgio Agamben e Achille Mbembe, como a produção do domínio interno pelo Estado pode produzir a destruição dos direitos humanos. A análise parte do exame do conceito de biopolítica, perpassa pelo conceito de campo e de homo sacer e alcança da ideia de necropolítica. A convergência destes conceitos ajuda na compreensão do fenômeno político moderno e dos riscos de serem adotadas políticas perversas, como as que definem, a partir dos lugares do poder, de quem deve viver e de quem deve morrer. O resultado é denúncia da instrumentalização da soberania e da possibilidade da emergência de políticas de destruição de corpos humanos e de grupos humanos específicos. Assim, a contribuição dos autores é uma lição muito importante e que deve ser vista como um alerta para o presente e para o futuro da humanidade. À vista disso, o método utilizado na pesquisa foi o compreensivo e a técnica de pesquisa utilizada foi a bibliográfica.
REPENSANDO A DEGRADAÇÃO DO REGIME HÍBRIDO NA VENEZUELA DE UMA PERSPECTIVA MINIMALISTA DE DEMOCRACIA
Authors: Oliveira André Silva de , Marques Rodolfo Silva
Published: December 2021

Após a redemocratização que varreu a América Latina nos anos 1980, a literatura em Ciência Política assinalou o surpreendente advento das democracias iliberais – tão bem descritas por Fareed Zakaria em icônico artigo de 1997 – e/ou regimes híbridos, conforme produção científica recente. Tais arranjos políticos pretendem modificar substancialmente as instituições da democracia representativa do tipo liberal, substituindo-as por desenhos consonantes com as concepções de democracia participativa ou radical. A discussão ganhou notável contribuição com a recente publicação do livro “Como morrem as democracias”, de Steven Levitsky e Daniel Ziblatt, que apresentam seu diagnóstico para a erosão gradual das instituições da democracia representativa do tipo liberal ao redor do planeta. O caso mais emblemático de regime híbrido na América Latina, segundo a literatura dominante, é o da Venezuela bolivariana que exibe hoje profunda divisão política e está à beira do colapso econômico. Por meio da revisão da literatura e a partir de uma perspectiva minimalista de democracia, o presente artigo busca repensar as causas que levaram à ascensão e, agora, ao iminente colapso do regime bolivariano que substituiu a oligarquia competitiva representada pelo Pacto de Punto Fijo (1958-1998). As conclusões principais são, dentre outras, a de que a robusta degradação do ambiente político-institucional venezuelano decorreu, no campo político, da miragem do outsider redentor e, na esfera econômica, do cálculo mágico de custo zero.

Authors: Colombo Silvana
Published: December 2021

No Brasil, a questão ambiental passou a ter relevância jurídica, pois o direito de viver num ambiente ecologicamente equilibrado foi erigido à categoria de Direito Humano Fundamental. Sob a perspectiva da Constituição Federal e da legislação infraconstitucional, o presente artigo analisa a participação popular nas decisões ambientais. Após, aborda-se os fundamentos constitucionais do direito à participação e os princípios que o norteiam. Posteriormente, menciona-se quais são os mecanismos disponibilizados pelo direito para viabilizar esta participação na seara do direito ambiental. Por fim, discute-se se a previsão legal destes mecanismos é suficiente para garantir a efetividade do direito à participação.

Published: December 2021

Bu çalışmada, Sorel çimentolu hafif betonların (SÇ) bazı mekanik ve yalıtım özellikleri incelenmiştir. SÇ numunelerinin yalıtım özelliklerinde iyileştirmeler yapabilmek için SÇ karışımları içerisine; hava sürükleyici katkı (HSK), ahşap talaşı (AT), mısır koçanı talaşı (MT), Puzolanlı madde (P), Afşin-Elbistan Termik Santral uçucu külü (AEUK) katkıları ayrı ayrı ikame edilerek numuneler üretilmiştir. Numuneler, bazı mekanik testlere ve yalıtım testlerine tabi tutulmuştur. Ayrıca referans numunelerin (R) farklı ortam koşullarına karşı dirençleri incelenmiştir. Numune dayanım değerlerinin yüksekten düşüğe sırasıyla SÇ, SÇ+HSK, SÇ+P, SÇ+AEUK, SÇ+AT ve SÇ+MT olduğu tespit edilmiştir. SÇ+AEUK numunelerinin çatlaması nedeniyle SÇ ve AEUK malzemelerinin birlikte kullanılmalarının uygun olmadığı gözlemlenmiştir. Suda bekletilen SÇ numunelerinin dayanımlarının zamanla düştüğü saptanmıştır. Ortam sıcaklık artışının R numunelerinin dayanımlarında 100 C’de artış, 500 C ve sonrasında düşüşe neden olduğu görülmüştür.

Sonuç olarak katkı kullanılan numunelerin R numuneye göre dayanımlarında düşüş, yalıtım özelliklerinde ise bazı iyileşmelerin olduğu gözlemlenmiştir. Saptanan değerler kullanılan katkıların türüne ve oranına göre farklılık göstermiştir.

Authors: Adane Teshale , Adugna Amare Tiruneh , Alemayehu Esayas
Published: December 2021

Adsorption offers an efficient, cost-effective, and eco-friendly method for the treatment of dye-laden wastewater. This work presents reactive red 198 (RR198) removal by adsorption using bentonite clay (BC) blended with sugar cane bagasse ash (SCBA). The adsorbent's surface morphologies, crystalline phase structures, functional groups, and specific surface before and after adsorption were examined using SEM, XRD, FTIR, and BET respectively. Central composite design (CCD) under response surface methodology (RSM) was applied to optimize independent and dependent variable values. The optimal parameters for RR198 removal using the blended adsorbent were 107 minutes contact time, 0.934 g/L adsorbent dose, and 15 mg/L initial dye concentration, and 85.2% RR198 removal efficiency was achieved. The sorption isotherms and kinetics were evaluated using various existing models. The Freundlich isotherm model (R2 = 0.95) and the pseudo-second-order equation best described the adsorption parameters and the RR198 adsorption kinetic mechanism, respectively. Desorption and reusability experiments in batch study confirmed that BC blended with SCBA can be used multiple times for dye removal from wastewater.
