Authors: Chaudhari S. R. , Deshmukh N. S.
Published: March 2022

The process typically begins with a botanist, ethno botanist, ethnopharmacologist, or plant ecologist who identifies the plant of interest. Collection may involve species with known biological activity for which active compound(s) have not been isolated (e.g., traditionally used herbal remedies). On the basis of intensive literature survey, Vigna mungo. phytochemical screening of the methanol extract and water extract of fruit powder of Vigna mungo showed the presence of various phytoconstituents such as Carbohydrates, phenolics, tannins resin, and protein. Heavy metal content was found below detection limit. In addition from the result of microbial load, it was found that raw material showed the presence of TPC, yeast and molds, E.coli but were found to be absent in both ethanolic and aqueous extracts. S.aureus and Salmonella were found to be absent in raw material as well as both the extracts. The viscosity of the extracted dried mucilage was compared with starch. The viscosity of the dried mucilage has viscosity comparable with starch. The polydispersity of isolated mucilage was obtained as 1.45. The polydispersity index (Mw/Mn) is used as a convenient measure of the range of molecular weight present in a distribution and is in the range of 1.4-6.0 for natural polysaccharide gums. The data of intrinsic viscosity was used to calculate the average molecular weight of the extracted mucilage and was found to be 1.8X103 kDa, which was comparable to Vigna mungo powder polysaccharides reported for its food applications (1.3X103 kDa). The mucilage of Vigna mungo consists of about 50.17 % of total carbohydrates. The total carbohydrates were estimated as dextrose by using anthrone reagent. The results showed that as the concentration of mucilage or sodium CMC increases, viscosity increases and consequently flow rate decreases gradually. The results obtained so far therefore have indicated that, the mucilage isolated from Vigna mungo has the potential to be used as a suspending agent; however, its actual in vivo performance on suitable animals or humans remains to be studied.

Published: March 2022

Antioxidative enzymes are a family of powerful free radical scavenging proteins, naturally synthesized by all aerobic organisms. Family of antioxidant enzymes include superoxide dismutase (SOD), catalase (CAT), peroxidase (PRX), thioredoxins /thioredoxin reductase (TrxR), and glutaredoxins/glutathione reductase (GPx). These oxidative enzymatic machineries, sequentially sequester singlet oxygen (O2 −) and Hydrogen Peroxide, which are the well-known reactive oxygen species. These enzymes can be intracellular as well as extracellular. In the present study, two most common soil fungi namely, Aspergillus Sp. and Cladosporium Sp. were cultivated by submerged cultivation on Potato dextrose broth and pellets were separated by filtration. Pellets were disrupted by detergent lysis method (0.5% Triton X 100, 1% CTAB, 1.5% Tween 80, 5% SDS). Culture media and cellular extracts were analyzed for intracellular and extracellular total proteins and their panel of antioxidative enzymes. Enzyme activity of SOD was carried out by Beauchamp and Fridovich method. Catalase and Peroxidase activities were determined by simple spectrophotometric method. In Aspergillus Sp.1.33 U of superoxide dismutase, 0.115 U catalase, 0.00097 U peroxidase activities per mg of protein was observed. Similarly, in Cladosporium Sp. 1.38 U Superoxide dismutase, 0.1460 U catalase, and 0.00150 U peroxidase activities per mg protein was recorded. Significant amount of antioxidative enzyme activity observed in both the test cultures. And comparatively, Cladosporium Sp has given promising results. Probably, with altered culture conditions and improved extraction procedures, still higher amounts of antioxidative enzymes would be expected.

Authors: Sharan Mahek , P. Meghana D.
Published: March 2022

There are three main cereal crops, rice, maize and wheat, in which, latter constitutes the major portion in the category. According to 2017 reports, it is known to be harvested around 772 million tonnes. Wheat is present in a diverse range and gets its elasticity, viscosity and properties of binding by the storage protein, Gluten, which is a secretory protein synthesised on rough endoplasmic reticulum. Gluten is roughly 78-85% of total wheat protein and made of gliadin and glutenins. There is a part of population with genes which develop autoimmune response against gluten that majorly affects the small intestine by damaging its lining and have to suffer from problems like pain in abdomen, joints, anaemia, osteoporosis and various gastro intestinal problems, developmental problems and problems like cramping, itching and lactose tolerance and excess weight loss. The patients who suffer from this disease undergo either biopsy of small intestine or serological assay like Rapid or ELISA for diagnosis. There are currently no treatments available for coeliac disease as the only way to curb this is strict gluten-free diet. There have been advances made in the field of agriculture, which resulted in production of the low gliadin content by use of gene editing technology and RNAi but the customer acceptance is the major issue faced. The most recent technological advancements in the field of biotechnology, like CRISPR-Cas9 is capable of producing the genetically modified wheat with lowest gliadin composition to curb the celiac disease impact in population.

Published: March 2022

A small village named Murti is situated along the bank of river Murti in Dooars. The adjacent area of murti is rich in insect biodiversity. Knowledge on the diversity and the role of Orthopteran insects in tea ecosystem of West Bengal including Dooars and Terai is very scanty. Hemocytes are the chief immune cells of insects. The number and shape of hemocytes can change rapidly in response to environmental stress and pollution. Grasshopper (Orthoptera) species were collected from Murti and adjoining areas and from different agricultural fields of North 24 Parganas (West Bengal). Hemolymph was stained by Giemsa, and Neutral Red. Cellular morphology and phagocytosis was examined. Normal cell shape and behavioural activities like phagocytosis, cell-cell fusion was observed in insects collected from Murti, and adjoining areas of Dooars. But in case of insect hemocytes isolated from different agricultural fields of North 24 Parganas and its adjacent sites showed altered shape and different phases of cell death like degeneration of nuclei, formation of membrane blebs and rupture of plasma membrane. Toxic environmental pollutants may be responsible for alteration of hemocytes size and function which may effect on biodiversity. Hemocytes can be used as an effective bio-indicator by which the health of the ecosystem can be screened.

A Corpus-Based Study of the Use of Temporal Markers in English Writing of Thai EFL Writers
Authors: Sophea Yin , Chanyoo Natthapong
Published: March 2022

The current study aimed to investigate the tendency to use temporal markers (TMs) in English writing by three different levels of Thai writers. Data used in this study were based on the Corpus of Thai Writers of English. The corpus size of approximately 8,800,000 words consisted of essay writing produced by intermediate and advanced student writers and professional writers from two Thai English newspapers. Fraser’s (2005) taxonomy of temporal markers was used as an analytical framework. Microsoft Excel was used to calculate the frequency of occurrences, while a Statistical Package for the Social Sciences (SPSS) was the primary research tool for data analysis. A one-way ANOVA reveals a statistical difference in the use of TMs among three groups of writers (p =.000). The intermediate and professional writers were found to prefer using temporal markers at a comparable ratio. However, the intermediate group used temporal markers in a more diverse attitude than the advanced ones. Six temporal markers (as soon as, immediately, meantime, meanwhile, originally, and subsequently) were hardly utilized in writing by all groups of writers. However, no significant differences were found regarding preferences on the position of the TM in the sentences. The findings improve teaching and learning of cohesive devices, especially temporal markers, in EFL writing classes. 
Complementarity and Variability of Wind and Solar Energy in Complex Terrain
Authors: Belu Radian , Koracin Darko
Published: March 2022

Wind and solar energy are expected to play a major role, in the near future electricity generation mix. However, wind and solar energy-based generation are intermittent and non-dispatchable, not being suitable to supply base-load electric power. Their greater penetration and grid integration are critical issues due to their inherent intermittency and variability. Moreover, there are strong evidence that wind and solar energy are showing complementary over appropriate time and space scales. This work investigates such spatiotemporal complementarity and variability as a means by which electricity planners, developers, and grid operators might advance uses and grid integration of wind energy. Over 14 years of synchronous wind velocity and solar radiation measurements at several sites, located in complex terrain of Nevada are used in this study. To do so we used auto-correlations and cross-correlations in wind speed and solar radiation time series, by applying detrended fluctuation analysis and detrended cross-correlation analysis.

Authors: Machado Renata Guanaes
Published: March 2022

Os gastos públicos devem ser constantemente monitorados pelos órgãos governamentais. Neste contexto, torna-se primordial a aplicação de tecnologia para a produção de informações estratégicas que apoiem ações de combate à corrupção e à má gestão dos recursos públicos. Com a disponibilização do Sistema de Informações sobre Orçamentos Públicos em Educação (SIOPE), o presente trabalho emprega técnicas de mineração de dados para a detecção de despesas atípicas no Ensino Fundamental, realizadas pelos municípios em 2018 – que podem constituir eventos ocasionais (como obras em escolas) ou representar indícios de irregularidades. Aplicou-se clusterização de municípios e algoritmos de detecção de anomalias em um grupo de municípios semelhantes. Os resultados alcançados (se o município é anômalo e seu grau de anomalia) podem ser agregados ao planejamento das ações de controle e, ainda, subsidiar a adoção de providências cabíveis por parte de demais instâncias, como o Ministério da Educação e conselhos de controle social.

Assim, longe de se contrapor ou mitigar avanços da normatização da política urbana nas últimas décadas, a Lei Federal nº 13.089/15 representaria um catalisador do direito à cidade, tanto para superar passivos quanto, principalmente, para dar sustentabilidade ao crescimento e às transformações das metrópoles.

Este trabalho é um estudo sobre o Estudo de Impacto de Vizinhança — EIV, dispositivo garantido pela Lei nº 10.257 (o denominado Estatuto da Cidade) e importante instrumento na preservação do espaço urbano, na garantia da função social da propriedade e na gestão democrática da cidade. A partir de um levantamento dos aspectos principais do EIV, acompanhamos sua regulamentação no território brasileiro e analisamos os projetos de lei propostos no Congresso Nacional com o objetivo de alterar o Estatuto da Cidade no que se refere ao EIV.
Mata do Planalto: um caso de resistência ao mercado imobiliário
Authors: Rugani Jurema M.
Published: March 2022

A Região Norte de Belo Horizonte, nas últimas décadas, tem sido alvo de intervenções que lhe conferiram potencial de centralidade, como a construção da Cidade Administrativa de Minas Gerais – CAMG, da Linha-Verde – ligando o centro da cidade ao aeroporto de Confins –, a expansão do trem metropolitano, entre outros, o que aumentou as possibilidades de articulação metropolitana naquela região. A isso segue-se a valorização do solo urbano, reforçando os interesses do grande capital imobiliário associado à produção dos condomínios fechados. Na busca por melhores localizações, o capital imobiliário – associado ao Estado – avança sobre os últimos fragmentos florestais, entrando em choque com os interesses da sociedade civil, que se organiza em função da preservação dessas áreas. Este artigo consiste numa reflexão sobre o processo de disputa entre o setor imobiliário, com o apoio do Estado, e a sociedade civil, pela destinação de um das últimas áreas verdes de Belo Horizonte, a Mata do Planalto.
Democracia e cidades: a experiência juiz-forana de revisão da legislação urbanística de edificações e de uso e ocupação do solo
Authors: Reis HelenaAna Beatriz Oliveira
Published: March 2022

Se propõe a resgatar a experiência de revisão da legislação urbanística de edificações e de uso e ocupação do solo da cidade mineira de Juiz de Fora ocorrida em 2013, procurando verificar quais são as características desse processo, em especial, quanto à dimensão da participação popular. Essa análise não se restringe apenas ao âmbito formal do processo legislativo na Câmara de Vereadores. Privilegia-se aqui a constante interação do referido processo formal com os diversos atores sociais da cidade. Destaca-se a atuação do movimento popular urbanista MaisJF na ampliação do debate público acerca das propostas de modificação legislativa e dos seus possíveis impactos no espaço urbano juiz-forano, ressaltando-se a importância das redes sociais nessa empreitada e a grande projeção alcançada pelo coletivo durante as jornadas de junho de 2013. A análise da democracia nesse processo toma por consideração o ambiente político-institucional brasileiro que consagra a participação popular no planejamento e na gestão das cidades em diversas normas amparadas pela Constituição Federal promulgada em 1988. Destaca-se dentre essas normas, a consagração do princípio da gestão democrática das cidades no Estatuto das Cidades. Para a construção desse trabalho são apresentadas, primeiramente, as características econômicas, sociais e político institucionais da cidade de Juiz de Fora para, em seguida, resgatar como ocorreu o processo de revisão legislativa. Esse estudo de caso foi feito por intermédio das técnicas de pesquisa de revisão bibliográfica, análise documental, sistematização de dados e entrevistas.
Derecho a la ciudad y gestión urbana democrática en villas y asentamientos precarios: aprendizajes a partir de experiencias en Argentina
Authors: Peñalva Gerónimo Leandro
Published: March 2022

En el presente trabajo nos proponemos abordar la temática referida a la necesidad de repensar las estrategias y políticas públicas en materia de integración urbanística, urbanización o procesos relocalización en villas o asentamientos precarios teniendo en cuenta las particularidades que tales ámbitos exhiben y los postulados que surgen del Derecho a la Ciudad vinculados a la idea de gestión urbana democrática. A partir de la relación entre las nociones de gestión urbana democrática, participación ciudadana y Derecho a la Ciudad planteamos la identificación de una serie de aprendizajes a través del análisis de algunas experiencias producidas en el contexto de casos complejos actualmente en camino de debate y construcción en Argentina.

A proteção das populações excluídas e grupos vulneráveis frente à COVID-19 pelo direito internacional dos direitos humanos
Authors: Osorio Leticia Marques
Published: March 2022

O presente artigo apresenta e analisa as resoluções e recomendações dos organismos de direitos humanos das Nações Unidas e do Sistema Interamericano relacionadas à prevenção e ao combate do coronavírus. O foco recai na abordagem de direitos humanos, colocados na linha de frente de proteção ao direito à vida e à moradia das populações que vivem nas cidades, sobretudo os grupos vulneráveis e excluídos. As diretrizes e recomendações para enfrentamento da COVID-19 emitidas por esses organismos, especialmente o Alto Comissionado das Nações Unidas para os Direitos Humanos, a Corte e a Comissão Interamericanas de Direitos Humanos, colocam as pessoas e comunidades afetadas pela pobreza no centro da atenção e resposta, frente ao perigo de omissão, exclusão ou desigualdade na oferta de informação e serviços públicos de prevenção ou tratamento da doença. Ao colocar as pessoas no centro das atenções, as respostas que protegem os direitos humanos colhem melhores resultados no combate à pandemia, garantindo cuidados de saúde a todos e preservando a dignidade humana.
O Fórum Direito à Cidade e a revisão do Plano Diretor de Natal: da forma ao conteúdo por uma cidade mais justa
Authors: Leôncio Érica Milena Carvalho Guimarães , Andrade Sarah de Andrade e , Brasil Amíria Bezerra , Ataíde Ruth Maria da Costa
Published: March 2022

O protagonismo histórico da Universidade Federal do Rio Grande do Norte como agente mediador e propositivo nos processos de participação social e o início da revisão do atual Plano Diretor de Natal estão entre as motivações para a criação do projeto de extensão Fórum Direito à Cidade UFRN, em 2018. Diante disso, o trabalho tem como objetivo, apresentar e discutir a trajetória do grupo no contexto de revisão do Plano Diretor, refletindo sobre a relevância, os limites e as potencialidades da extensão como ponte entre a Universidade e a sociedade, no enfrentamento das lutas urbanas cada vez mais acirradas no contexto de avanço das políticas neoliberais e sua materialização nas disputas territoriais e afirmação da segregação socioespacial. Destaca-se também o desmonte das políticas sociais construídas ao longo das décadas de 1980 e 1990, em especial da participação popular nos seus processos de construção, implementação e gestão. Em Natal, evidencia-se a disputa de narrativas entre vários segmentos da sociedade na relação entre a forma e o conteúdo no desenho da cidade, com uma constante depreciação dos argumentos dos movimentos sociais e da Universidade, em contraponto à defesa da prevalência do discurso modernizante que traduz os interesses dos segmentos vinculados ao capital imobiliário.
O desmonte da política ambiental do Brasil: da boiada à desregulação dos mangues e restingas
Authors: Taborda Elaine , Tierno Rosane de Almeida
Published: March 2022

Na última semana de setembro de 2020, o CONAMA – Conselho Nacional do Meio Ambiente deliberou pela revogação da Resolução nº 284/2001, que dispõe sobre o licenciamento ambiental de empreendimentos de irrigação; da Resolução nº 302/2002, que trata dos parâmetros, definições e limites de áreas de preservação permanente de reservatórios artificiais e o regime de uso do entorno, e da Resolução nº 303/2002, que tem por objeto os parâmetros, definições e limites de áreas de preservação permanente. Essas revogações, materializadas na Resolução CONAMA nº 500/2020, têm sido objeto de verdadeira perplexidade pela sociedade civil, sistema de justiça, meio acadêmico, e sistema político. Contudo, conforme veremos no presente artigo, a revogação arbitrária desses importantes marcos legais protetivos da diversidade de biomas brasileiros, materializa-se como decorrência do desmonte da política ambiental que vem sendo perpetrada desde que o governo federal atual ingressou no poder, em janeiro de 2019. Decorre assim, de uma lógica perversa da prática de atos coordenados para a efetiva fragilização de todo o sistema protetivo e fiscalizatório do meio ambiente,
O direito à moradia digna: de direito fundamental à transformação em ativo financeiro
Authors: Alfonsin Betânia de Moraes , Lanfredi Eduarda Schilling
Published: March 2022

Considerando o processo de urbanização no Brasil e os impactos ocasionados na efetivação de direitos fundamentais dos indivíduos, o presente trabalho tem como propósito analisar a relação estabelecida entre o crescimento dos grandes centros urbanos e a transmutação do conceito e da finalidade do direito à moradia digna no atual estágio do capitalismo sob dominância financeira. Para tanto, inicia-se o trabalho abordando a forma com que se sucedeu o desenvolvimento urbano no Brasil e as consequências sofridas pela população migrante. Em seguida, são abordados os instrumentos implementados pelo Estado para minimizar os efeitos da urbanização desigualmente distribuída no território e profundamente hierarquizadora do espaço urbano no Brasil. Por fim, verifica-se que o Estado, com o advento do capitalismo financeirizado e no contexto do atual governo brasileiro, opta por abandonar a efetivação dos direitos fundamentais, especificamente o direito à moradia digna, para privilegiar a adoção uniforme da titulação via direito de propriedade plena. Para tanto, adotou-se o método indutivo e a técnica da pesquisa bibliográfica. Desta forma, observou-se que o Estado, com as transformações experimentadas pelo sistema capitalista, eximiu-se de seu papel primordial de reconhecimento e defesa dos direitos fundamentais outorgando tal responsabilidade, especialmente no tocante ao direito à moradia digna, ao próprio particular, através da validação de  financeirização da terra, da moradia e da cidade, aprofundando desigualdades sociais e perpetuando os processos de acesso irregular ao solo urbano no país, bem como reforçando o direito de propriedade.
