Evaluation of the Efficiency of Cassava Peel as a Cement Retarder in Oil Well Cementing
Authors: A Cookey G. , F Chuku , L Konne J.
Published: April 2023

Cementing around the casing in oil and gas wells provides proper zonal isolation, holds the casing in place and prevents fluid migration. This procedure is an important part of completing the process and well plugging for abandonment. Retarders are one of the most important additives in oil well cementing if the desired pumping time of cementitious slurry is to be achieved. These retarders can be extracted from natural sources or chemically synthesized. However, synthesized retarders can have significant environmental effects. Thus, this study evaluated the efficiency of cassava peel powder as a biocompatible retarder in oil well cementing and its cement slurry properties.Cement slurry was prepared, and the thickening time and rheology were tested according to API RP 10B2 (2005) procedures. The performance of cassava peel powder as an oil well cementing retarder was tested at various concentrations and temperatures. Its retardation property was compared with those of a commonly used lignosulfonate-based and a synthetic retarder, respectively. The results obtained at various concentrations of the retarders showed that the thickening time for cassava powder at 70Bc was 02hr: 17mins for 0.03% by weight of cement (%bwoc), 02hr: 20mins for 0.06% and 02hrs:32mins for 0.1%bwoc. The results for lignosulfonate-based retarder are 02hr: 19mins for 0.03%, 02hr: 30mins for 0.06% and 03hr: 02mins for 0.1% bwoc. For the synthetic retarder, the results are 02hr: 29mins for 0.03%, 02hr: 31mins for 0.06%, and 02hr: 51 mins for 0.1% bwoc. These results suggest that the retarding ability of cassava peel powder in oil well cementing is much comparable with those of the existing retarders. It was also observed that cassava peel demonstrates a high-performance concentration response without hampering other cement properties.

A dessalinização consiste na remoção de sais da água salobra ou da água do mar. Dentre os vários métodos de dessalinização de água conhecidos, os principais são o térmico e de membranas, onde a osmose reversa é a mais comum, e por eletrodiálise. A dessalinização da água é uma alternativa de aporte hídrico que visa atender as demandas por água potável. O objetivo desse estudo foi realizar uma prospecção tecnológica de patentes relacionadas à dessalinização de água. Foram consultados os seguintes bancos de dados on-line de patentes: Instituto Nacional da Propriedade Industrial (INPI), World Intellectual Property Organization (WIPO) e European Patent Office (EPO) usando diversos termos descritores. Com os resultados obtidos foram feitos levantamentos cronológicos de depósito, distribuição das patentes por países e classificação das patentes de acordo com a Classificação Internacional de Patente (CIP). Verificou-se que o banco de dados da WIPO apresentou o maior número de depósitos (208.425), seguido pelo EPO (190.906) e INPI (118). De acordo com a CIP, a maioria das patentes apresentaram estas classificações: 52,91% contemplam a seção C (Química; Metalúrgica), seguida pela seção B (Operações de procedimentos; Transporte) com 39,84%. O maior número de patentes ocorreu em 2019, com 3.026 depósitos, sendo que os Estados Unidos da América e a China detêm o maior número de patentes registradas. Frente ao cenário de crescimento populacional mundial e às mudanças climáticas, a promoção de novas tecnologias que reciclem a água apresenta uma alternativa promissora.

Dentre as inúmeras patologias que estimulam o declínio funcional de idosos, vale a pena destacar a hanseníase. Uma doença infecciosa, crônica e dermatoneurológica, que compromete os nervos periféricos, podendo agravar as dificuldades funcionais assumindo caráter incapacitante, além de causar deformidades físicas quando não tratada adequadamente. Neste estudo descritivo com abordagem quantitativa, objetivou-se analisar os dados coletados, a fim de avaliar as características epidemiológicas, diagnóstico clínico e classificação, através da ocorrência da Hanseníase na população idosa em relação às outras faixas etárias no estado de Alagoas entre os anos de 2007 a 2020, a partir dos dados do Sistema de Informação de Agravos de Notificação (SINAN). Houve uma prevalência do sexo masculino compondo 50,2% da população total. A maior faixa etária foi 29-39, porém houve uma quantidade significativa da população idosa acometida. Quanto à classificação operacional, houve maior prevalência da forma multibacilar, compondo 70,49% dos casos. Em relação ao grau de incapacidade, o sexo masculino apresenta maior predominância nos casos de incapacidade e comprometimento físico que o sexo feminino, sendo o grau I acometendo a maioria dos pacientes masculino e feminino. Dessa forma, conclui-se que os cuidados e o tratamento devem ser assertivos e iniciados o quanto antes, com vistas à redução, e das incapacitações presentes em graus de lesões, na população idosa acometida pela doença.

O uso de plantas de cobertura pode otimizar a proteção do solo, índice de matéria orgânica e a ciclagem de nutrientes, favorecendo o aumento da produtividade de grãos. O objetivo deste estudo foi avaliar a influência das plantas de cobertura do solo na produtividade da cultura do milho verão, na altura de planta e umidade. O experimento foi conduzido no município de Ubiratã-PR, visto que, ainda não há nenhum experimento a campo, desenvolvido nas condições edafoclimáticas desta região. Para isso, utilizou-se o híbrido Morgan 545PWU, em delineamento de blocos casualizados (DBC), com cinco repetições e cinco tratamentos, sendo: T1- Testemunha; T2- Aveia branca; T3- Milheto; T4- Brachiaria e T5- Mix 210. Os dados foram submetidos ao teste de Shapiro-Wilk e de Barlett. E, as médias, posteriormente comparadas pelo teste de Tukey a 5% de probabilidade. O uso do Mix 210 para cobertura do solo, proporcionou maior produtividade, altura de planta e umidade de grãos para o híbrido estudado. Isto sugere que a utilização de espécies em associação tende a proporcionar maior fixação de N, em função da grande diversidade de raízes. Além disso, o incremento na produtividade, obtido deve-se ao manejo sustentável, empregado aqui, pelo uso de espécies vegetais em substituição a fertilizantes artificiais.

Pesquisas sobre a utilização da Modelagem da Informação da Construção (BIM) vêm ganhado bastante espaço ultimamente. A tecnologia BIM traz inúmeros benefícios para os projetos de engenharia por meio da integração de dados multidisciplinares e a criação de representações digitais detalhadas. Por esse motivo, o presente trabalho teve como objetivo analisar o estado da arte da integração do BIM com os softwares Abaqus, Ansys, Robot e SAP2000, muito utilizados para projetos estruturais e simulações numéricas. Para tanto, foi realizada uma revisão sistemática da literatura nas bases de dados Web of Science e Scopus, buscando artigos que associavam o termo BIM com cada software analisado. Um total de 30 artigos foi encontrado inicialmente e, após uma filtragem dos mesmos, restaram 17 artigos relevantes, que foram então analisados e discutidos um a um. Após a análise dos artigos, diversos benefícios foram encontrados, contudo, lacunas e limitações também foram identificadas, mostrando a necessidade de estudos sobre a interoperabilidade entre o BIM e os softwares estruturais.

Published: April 2023

Quando as necessidades fisiológicas humanas são acometidas, algumas terapêuticas para serem alcançadas podem demandar recursos específicos, tais como o uso de biomateriais. Assim, para dar suporte à vida, desenvolveram-se ao longo dos anos diversos dispositivos, como sondas/cateteres para o sistema digestório, respiratório, urinário, vascular, entre outros. Esses dispositivos médicos diferem desde a constituição dos materiais a designs. Nesse universo, elegeu-se discorrer sobre os cateteres venosos quanto aos critérios de dimensões, durabilidade, inserção, infecção/biofilme, material, inovações, avanços tecnológicos e eventos adversos. O estudo realizou-se por meio de uma revisão bibliográfica sistemática na pubmed, google acadêmico e, materiais complementares foram elencados, porque poderiam possibilitar alçar esses critérios e contribuir com informações fundamentais ao entendimento da interação do cateter com o sangue. A relevância do presente estudo, deve-se ao overview de cunho interdisciplinar com foco sobre o cateter venoso. Percebeu-se, que ocorreu o desenvolvimento tecnológico desses dispositivos médicos ao longo dos anos, porém, ainda se encontra na literatura traços conflitantes acerca do cateter, cita-se: a obstrução por coágulo sanguíneo relacionado ao uso de anticoagulante x solução fisiológica como formas de resolver o problema; diferentes recomendações da durabilidade do cateter atrelado ao tipo material. Portanto, concluiu-se que são complexas as circunstâncias do cateter venoso, assim como as relações de interface substrato/sangue e eventos adversos. Nota-se, que os eventos associados ao cateter têm caráter interdisciplinar, envolvendo conhecimentos da biotecnologia, farmacologia, enfermagem, engenharia, etc.

Interações medicamentosa entre Bupropiona e anti-hipertensivo e entre Bupropiona e antidepressivo em pacientes tabagistas: uma revisão de literatura
Authors: Lima Ana Débora Coutinho , Pachú  Clésia Oliveira
Published: April 2023

O tabagismo é uma doença crônica que afeta o funcionamento normal do cérebro e do coração, podendo causar depressão e hipertensão. Nesse sentido, a terapia prescrita para pessoas portadoras de dependência à nicotina e hipertensão associadas é a bupropiona, um fármaco antidepressivo atípico que melhora os sintomas de abstinência de quem deseja parar de fumar. Tal terapia deve ser feita com cautela, porque há interações medicamentosas a serem consideradas entre a bupropiona, agentes anti-hipertensivos e antidepressivos, podendo trazer riscos ao paciente. Diante disso, foi feita uma revisão de literatura, com o objetivo de identificar as interações medicamentosas presentes entre bupropiona e medicamentos anti-hipertensivos, e entre bupropiona e fármacos antidepressivos. Sendo assim, realizou-se buscas nas bases de dados Google Scholar, Periódicos Capes e Science Direct, para encontrar trabalhos entre os anos 2018 e 2022. Foram encontrados 130 trabalhos, nos quais 25 artigos foram analisados e 17 artigos foram selecionados. Dessarte, notou-se que dentre as classes diuréticos e anti-hipertensivos analisadas, a única classe que apresenta interação fármaco-fármaco com a bupropiona é a dos bloqueadores adrenérgicos. Dessa maneira, ocorre um antagonismo competitivo entre bupropiona e os bloqueadores adrenérgicos pelas enzimas hepáticas CYP2D6, provocando o aumento da concentração plasmática dos bloqueadores adrenérgicos, visto que a bupropiona é um forte inibidor dessa enzima, podendo gerar riscos de hipotensão e queda da frequência e contratilidade cardíacas do paciente. Quanto à interação medicamentosa entre bupropiona e antidepressivos, foi visto que a bupropiona interage com a fluoxetina e com antidepressivos tricíclicos, provocando riscos de arritmias e hipertensão.

Published: April 2023

A pele é um revelador do envelhecimento saudável, em que diversos recursos buscam desacelerar a sua senescência e impedir os danos causados pelos fatores extrínsecos. A curcumina, composto ativo da Curcuma longa L., vem sendo estudada como um possível adjuvante antienvelhecimento, por apresentar propriedades funcionais, em principal, as atividades antioxidantes e anti-inflamatórias. Entretanto, a sua instabilidade química e biodisponibilidade dificultam a sua utilização. Neste contexto, pesquisas vêm sendo realizadas com o propósito de encapsular a cúrcuma em nanoestruturas. O objetivo desta revisão é atrelar o potencial da curcumina no processo de envelhecimento cutâneo às abordagens que utilizam a nanotecnologia, através de nanoestruturas lipídicas, a fim de melhorar sua aplicabilidade no uso tópico. Para obtenção dos dados, foi realizada uma pesquisa qualitativa através de uma busca sistemática utilizando os bancos de dados Google Acadêmico, Web of Science e Pubmed com diferentes combinações de palavras-chaves. Apesar de inúmeros estudos correlacionando a curcumina e a nanotecnologia, neste trabalho foi possível observar a escassez de resultados que trazem a participação desta substância no processo de envelhecimento, sendo necessária uma maior exploração por meio de pesquisas, tendo em vista o grande interesse comercial da curcumina para o desenvolvimento racional de fármacos.

Published: April 2023

The aim of this study was to evaluate the incidence of UTI in Salahadin governorate/Iraq, identify the causative agents, their antibiotic sensitivity and their ability to form biofilms; such studies are mandatory to determine the empirical therapy of such cases. A total of 650 urine samples were collected. Two hundred and fifty samples were cultured, as suspected of having UTI, and 193 samples (77.2 %) showed growth (Positive culture), while 57 samples (22.8 %) were negative cultures. Gram-positive bacteria were the predominant cause of UTI (66.7%), while Gram-negative species were found in 33.3%. Staphyloccus spp. were the predominant Gram-positive genus to isolate from UTI patients, while E. coli was the predominant among Gram-negative bacteria. The isolates were tested for antibiotic susceptibility and biofilm formation. The most effective tested antibiotic on the Gram-positive isolates was Nitrofurantoin followed by Chloramphenicol (resistance percentage 19 and 20% respectively), and the least effective one was Azithromycin (64% resistance). While the most effective tested antibiotic on the Gram-egative isolates was Amikacin (only 8% resistance), and the least effective one was erythromycin (98% resistance). Biofilm detection by Congo red agar (CRA) method and microtiter plate (MTP) assay were done; the results showed that by CRA method 81.3% of isolates were biofilm formers. While 96.7% of isolates were detected as biofilm formers by microtiter plat assay. Generally, biofilm formation was more predominant among Gram-positive isolates than Gram-negative ones

Vaccine uptake and coverage in susceptible populations are needed through effective vaccination campaigns to address the COVID-19 pandemic in South Asian countries. We aimed to measure the pooled proportion of COVID-19 vaccine hesitancy in this regard. Research articles published between January 1, 2020, to December 31, 2021, were searched through Medline, PubMed, Cochrane, Google Scholar, and the WHO COVID-19 database. The Joanna Briggs Institute (2014) tool for prevalence studies was used to assess data quality. We performed a meta-regression test and a sensitive analysis among the studies and used the DerSimonian and Laird random-effects model to measure the pooled effect estimates. Subgroup analyses were performed concerning vaccine hesitancy, countries, study population, study level, and the time since the first outbreak of the pandemic. A total of 43 studies out of 598 published articles across the eight countries in South Asia were included. The pooled proportion of COVID-19 vaccine hesitancy was 26.5% (95% CI [22, 31], I2 = 99.59%). Vaccine hesitancy was higher in Afghanistan (37%), Pakistan (33%), and Bangladesh (28.9%); among the general population (29%); at community levels (27.9%); and the duration of time of 1–12 months since the first outbreak in each country (27.5%). Vaccine hesitancy exists in South Asia with different rates among countries, population sub-groups, communities, study- levels, duration of time since the first outbreak, and study population. Therefore, enhancing public awareness of vaccination and vaccine hesitancy is required to prevent future pandemics.

This study aims to determine the prevalence and associated factors of turnover intention among interprovincial migrant workers in garment companies in a rapidly urbanizing area of Vietnam. This study employed a mixed method approach, beginning with in-depth interviews with 12 migrant garment workers to develop survey instruments, which were then used in a quantitative survey. The survey recruited and interviewed 328 inter-provincial migrant workers working in garment factories using a social mapping sampling method. Multivariable backward stepwise logistic regression analysis was used to investigate factors associated with worker turnover intention. The results show a high prevalence of turnover intention (46.3%) among the survey participants. High psychological demand (OR = 2.5, 95% CI [1.4, 4.4], p < .001), low job control, income dissatisfaction (OR = 3, 95% CI [1.5, 6], p < .01), migration intention (OR = 13, 95% CI [7, 24], p < .001) and male gender (OR = 2.5, 95% CI [1.3, 4.8], p < .01) are factors significantly associated with turnover intention among migrant workers. This study provides a model for understanding migrant laborers’ turnover intentions in the garment industry, as well as critical data for developing needs-based intervention programs for this vulnerable group, such as appropriate resettlement strategies and the creation of a healthy working environment, both of which could play essential roles in the garment industry’s workforce retention.
Leading-Edge Cone Method for Waverider Design

Published: April 2023

Leading edge is a primary element that forms waverider configurations. To design waveriders from given leading edges directly and accurately, a new method named the “leading-edge cone method” has been proposed. The leading-edge cone is a conical surface whose tip lies on the leading edge. The shock surface related to the leading edge is the enveloping surface of multiple leading-edge cones. The geometric relationship between leading-edge cones and the shock surface is a particular case of the Apollonius problem in mathematics. Six conditions of leading-edge cones have been discussed, and mathematical expressions of the shock surface are presented. The leading-edge cone method is then established based on these mathematical expressions. Three test cases and three application cases are employed to validate the effectiveness and accuracy of the leading-edge cone method. Results show that all the cases designed by the leading-edge cone method meet the design requirements, and shocks derived from given leading edges coincide well with the shocks generated in numerical simulations.

This study presents a fully automated Cartesian-grid-based compressible flow solver, named FrontFlow/Violet Hierarchical Cartesian for Aeronautics based on Compressible-flow Equations (FFVHC-ACE), for large-eddy simulation (LES) and its aeronautical applications. FFVHC-ACE enables high-fidelity LES of high-Reynolds-number flows around complex geometries by adopting three key numerical methods: hierarchical Cartesian grids, wall modeling in LES, and the kinetic-energy and entropy preserving (KEEP) scheme. The hierarchical Cartesian grids allow fully automated grid generation for complex geometries in FFVHC-ACE, and high-fidelity LES of high-Reynolds-number flows around complex geometries is realized by the wall modeling and the KEEP scheme on the non-body-fitted hierarchical Cartesian grids. We apply FFVHC-ACE to wall-modeled LES around high-lift aircraft configurations at wind-tunnel-scale Reynolds number [Formula: see text] and real-flight Reynolds number [Formula: see text], demonstrating the capability of FFVHC-ACE for fully automated grid generation and high-fidelity simulations around complex aircraft configurations. The computed flowfield and aerodynamic forces at the wind-tunnel-scale Reynolds number agree well with the experimental data provided in the past AIAA High Lift Prediction Workshop (Rumsey et al., Journal of Aircraft, Vol. 56, No. 2, 2019, pp. 621–644). Furthermore, the wall-modeled LES at the real-flight Reynolds number shows good agreement of the lift coefficient with flight-test data.

Authors: Sourav Kastha  , Pranabpati Karmakar
Published: April 2023

The pandemic COVID-19 has a catastrophic impact on people’s social activities across the globe, and it’s necessary to pay profound attention to this. This study focuses on a detailed comparison of the social activities and difficulties faced by the general population during COVID-19 in between urban and rural areas of the Southern part of West Bengal, India. The data were obtained through the online Google Form, using snowball sampling technique from 20.05.2020 to 08.06.2020. The respondents of ≥18-year age was considered for this study. Total 472 respondents of 69 villages and 47 town areas have taken their perception through a said questionnaire, among them 43.88% and 56.12% respondents were residing in the rural and urban region respectively. Two modified five-point Likert-type scales were adopted: Social Activity Scale (SAS-15: Cronbach’s alpha of .875 for urban and .720 for the rural region) and Social Difficulty Scale (SDS-18 Cronbach’s alpha of .884 for urban and .914 for the rural region). It was used to study the respondent’s attitude towards social activities and difficulties in rural and urban regions based on five demographic aspects. Non-parametric Kruskal-Wallis test was also performed to know the relation between demographic aspects and social activities. This study reveals that the rural respondents were engaging themselves in more social activities (Mean of SAS score 57.49 and 54.78 respectively) and facing more difficulties (Mean of SDS score 42.59 and 38.03 respectively) compared to urban respondents. Overall, mild disagreement and little difficulty have been observed in social activities and difficulties, respectively.
CONSTRAINTS IN AGRICULTURAL PRODUCTIVITY OF LATERITIC SOIL OF WEST BENGAL
Authors: Dr. Soumita Ghosh
Published: April 2023

In an agrarian economy-dominated livelihood system, soil factor considered to be an essential determinant to prioritize the choice for crop selection and productivity. The laterite soil is formed under conditions of high temperature and heavy rainfall with alternate wet and dry periods, which leads to leaching of soil, leaving only oxides of iron and aluminum. It lacks fertility due to a lower base-exchanging capacity and a lower content of nitrogen, phosphorus, and potassium. Laterite soil is found in the western plateau region (mainly found in the parts of Birbhum, Bardhaman, Bankura, Purulia, West Midnapore districts) of West Bengal. This soil is red in colour, acidic in nature (from 5.5 to 6.5 approx.) and poor in organic matter, calcium, phosphates and nitrogen. Overall, leaching under slight to very high soil erosion makes this soil infertile; though with proper irrigation facilities, scope of growing vegetation and cultivation can be possible in this soil. It has been observed that, Increase in yield of paddy with nitrogen is not significant in cultivation; but, when phosphate is added along with it high responses are obtained, indicating a typical phosphate deficient tract. The present paper tries to highlight on the factors responsible for the limited scope of agricultural productivity on lateritic tracts of West Bengal, which need to be addressed for effective land use planning and management in future.
ENVIRONMENTAL AND ECOLOGICAL AWARENESS IN THE MAHABHARATA
Authors: Anima Bairagi
Published: April 2023

This article focuses on environmental and ecological awareness in the perspective of the Mahabharata, a noble Hindu epic. The existence of good life on this planet- earth, is not possible without pure environment. Today, the interest in environmental and ecological awareness is seen spreading its wings to humanities. It embraces literature, art, music, history, religion and many branches of knowledge. The Hindus have responded in a very positive way for the concern of ecology. They say “One tree is equal to ten sons”. Sanskrit literature is not only rich in the grammatical composition and romantic expression but also in knowledge about environment, its destruction and the need for its protection which come up in many contexts every now and then whenever any attempt is made to study this literature. Starting from the Vedic age till now it carries a number of appearances in the writings of scholars. This need to be explored in detail as the vast size and span of it leaves enough scope for researchers to dig up those sources of knowledge. Mahabharata reflects a conflict over social policy in the face of an environmental disaster. The epic teaches to love and respect all the creatures equally. The paper would include images on environment and ecological awareness as raised in text.

Authors: Dr. Tanmoy Dhibor
Published: April 2023

Urbanization and modernization are closely interlinked to each other and hence they are now in the forefront of research in social sciences. The most significant aspects of worldwide post-war demographic phenomena are associated with the fast growth of urban area in developing countries. However, the pattern of urban growth varies according to the spatio-temporal scale. The study of trend and pattern of urbanization in spatio-temporal variation is important for any urban development planning. Urban Growth gives rises to various types of economic, industries benefit from concentration of suppliers and consumers, which allow saving in communication and transport costs and also exerts adverse effect on environment. In India, the highest urbanized state is Maharashtra whereas the rate of urbanization is comparatively less in West Bengal in comparison with other states of India. Uneven rate in urbanization process is also found in different parts of the state of West Bengal too. South 24 Parganas and Bankura are two marginal districts situated in the south-eastern and western part of the state has been selected for the study. These two districts have different level of urbanization depending upon their distinctive socio-economic conditions. The present study is an effort to compare the spatio-temporal pattern of urbanization between these two districts and trace out the prime responsible causes behind such variations.
A Sociological Outlook of Knowledge in the Age of Post Truth Era
Authors: Soumitra Sarkar
Published: April 2023

In Media trends have steadily increased in the past few decades, given the current social context. This indicates how much the media has naturally affected the scope of knowledge by presenting a rich array of digital and print media. It has been difficult for people to reveal the true truth in the current context due to the effects of post-truth ideology. It is very difficult to say that any one subject will be properly presented to all equally in a volatile world where globalization has ushered in the unraveling of the true meaning of knowledge. Today's society depends heavily on the media to portray historical events and to portray the nature of political representation. Digital and print media are being used in this case to present an image that people believe to be true. Modern society has thus become a booming market for post-truth ideologies. A true essence has a form that changes with time and place, so there is no such thing as a real truth from a sociological perspective.

Floods are common natural disaster stirring in most parts of the world. It is considered to be one of the important natural climatic component and climatic variability. Ecology is an important aspect of our environment that keeps our environment quivers. The spectrum of river flow variability is a most important ecologically component in a river ecosystem. This research study is to examine check Floods, causing cataclysm, frequently occur in the Dwarka River basin. In this study, We used Remote Sensing (RS) and Geographical Information System (GIS) Techniques which can helped us to identified and prepared Flood Risk zonation Mapping by the accruing and analyzing massive amount of data in short time. The main objectives are (i) To find out the Flood zone assessment affected by Dwarka river basin using various technique for flood causes influence to physical elements. (ii.) To determine the ecological impact of flood in Dwarka river basin. When results were overlayed with various data (Qualitative and Quantitative) regarding this study area, it was seen, that the settlement and agricultural areas in the study area will be affected by floods. The upper part of the Dwarka river basin is more flood effected due to over flowing of water which is one of reasons for high rainfall and also, ecological environmental problems, such as soil and water pollutions, agricultural land degradations causing flood sediments as well as the ecological deterioration on living environment of natural flora and fauna will be caused by floods in the Dwarka River basin. This Research will be helpful to flood management program, dissection makers and planning in local administrative level.

Published: April 2023

To improve women's status in society, education is a need. Women with education can contribute significantly to the socioeconomic advancement of society. As a means of regaining their standing both inside and outside of their families, education decreases gender inequalities. It is a crucial element for the welfare, prosperity, and empowerment of women. Both the government and civic society in India have been particularly concerned about the education of women, as educated women can contribute significantly to the country's growth. Women's empowerment focuses on education since it gives them the tools to respond to difficulties, accept their conventional roles, and improve their lives. Rural areas have very slow educational growth for women. Rural areas have very slow educational growth for women. This clearly indicates that a significant portion of women in our nation are still uneducated, frail, ignorant, and exploited. The most effective instrument for changing a woman's standing in society is education of women. After enacting the 86th Constitutional Amendment, which declared that every Indian child had a basic right to education from ages 6 to 14, the Indian government introduced the EFA programme in 2002. However, the status of girls' education is not increasing in accordance with the criteria set for women. The current article aims to explain the current state of women's education in India.
Adiponectin: The Wonder Hormone in Therapy of Obesity
Authors: Dr. Tanima Paul (Das)
Published: April 2023

Adiponectin is a crucial hormone and adipocytokine secreted mainly by adipocytes of adipose tissue. Insulin plays a central role in the synthesis of adiponectin. Adiponectin plays an important role in insulin sensitivity by increasing insulin release from pancreas, increasing basal glucose and insulin-stimulated glucose uptake in fat tissues, preventing hepatic glucose production, increasing fatty acid oxidation and storage of fat in subcutaneous tissues of liver or skeletal muscle which reduces visceral fat mass and systemic inflammation, improved glucose and fat metabolism and increased insulin sensitivity. Therefore increased expression of adiponectin is associated with therapeutic effect on treatment of a wide range of metabolic diseases like diabetes mellitus, obesity, inflammatory and cardiovascular diseases. Alterations in adiponectin levels have been demonstrated to directly influence lipid and glucose metabolism that in turn increase lipids, free fatty acids and inflammatory cytokines synthesis. Recent therapeutic approaches have focused on the indirect upregulation of adiponectin through various therapeutic strategies and/or lifestyle modifications. Loss of weight,dietary modification, lifestyle changes and/or medications including orlistat, sibutramine, rimonabant, increase adiponectin levels.Insulin sensitizers, like thiazolidinediones, and lipid-lowering composition like statins and fibrates, upregulate adiponectin and may influence Insulin Résistance. These approaches ushers a new era in the management of cardiovascular diseases, diabetes mellitus and metabolic syndrome. The current review focuses on these new insights of the therapeutic role of adiponectin to reckon with.
