Published: November 2023

Regulatory bridge is a hydraulic structure to control the flow of water through a water body. It can also act a bridge for commuting between the two shores of the river across which it is built. The present study focuses on the feasibility assessment of the need of a regulatory bridge at at Kannattupadam, across Kurumali River. Presently a temporary bund is built each year at the proposed site to accommodate both water storage and two-wheeler traffic between the two banks of the river. The transportation infrastructure across the river is very weak, especially during the wet season. The periodic construction of the temporary bund will finally result in land filling and is not a sustainable approach. Considering the above situation, the need for a regulator cum bridge feasibility study had been intense for a considerable amount of time, and it initially appears that such a project is highly beneficial for the development of the area in terms of improving water storage and transportation facility; The main objective of our work is to investigate about the feasibility of a regulator cum bridge for the storage of river water and benefit analysis of the proposed bridge was conducted based on traffic survey and questionnaire survey among the road users and the people residing in the proposed location. The estimation of the quantities needed for the construction of regulatory bridge was obtained in the quantity survey. The amount which is required for the construction of the bridge for the following quantities was also estimated. Cost benefit analysis of the bridge was done so that the feasibility study for the bridge could be completed.

Representing autism as a discourse within ableist economies of doubt
Authors:   , Ebben Hannah
Published: November 2023

This thesis explores the theme of epistemological uncertainty about autism in visual culture. It is based around the research question ‘What is the epistemology of autism as a discourse in the film Extremely Loud & Incredibly Close (2011), the CBBC Newsround special “My Autism and Me” (2011), and the YouTube video In My Language (2006)? My study of the representation of autism is constructionist and solely focused on autism as a discourse, and not on autism as a clinical condition. My critical consideration of the autism category in society is informed by Fiona Kumari Campbell’s definition of ableism: the normative power enforcement of abled-centric social standards. “My Autism and Me” and In My Language contain personal accounts of autistic people. In my thesis, I regard the personal account not as a static source on inside knowledge on life with autism, but as a relational process of acknowledgement of cultural texts as autistic voice. Each case study conveys the state of ‘not-knowing’ autism. Extremely Loud & Incredibly Close portrays a character who is not definitively diagnosed with autism and whose characterisation invites audience speculation about the nature of his condition. “My Autism and Me” renders the abstract notion of autism concrete for a young audience and explains that the cause of autism is still unknown. In My Language problematises certainties about non-verbal autism by resisting the interpretation of non-verbal self-expression as meaningless. My thesis theorises these topics of speculating, rendering and resisting as important aspects of the cultural significance of epistemological doubt on autism. I propose the term ‘political economy of doubt’ to highlight that uncertainties on knowing autism are at the forefront of meaning exchange on the concept of autism. I argue that my case studies continue, rather than criticise, ableist normativity with their peculiar themes of knowing and not-knowing autism.

Authors: Kaasbøll Jannike , Brøndbo Per Håkan
Published: November 2023

Bakgrunn: Denne artikkelen er en kunnskapsoppsummering og klassifisering av tiltaket Cool Kids, et program med hovedmålsetting å hjelpe barn og unge i alderen 6-18 år å håndtere angst og relaterte vansker. Programmet kan tilbys både individuelt og i gruppeformat, med ca. 10 møter. Cool Kids -programmet er teoretisk forankret i kognitiv adferdsterapi. Sentrale metoder i programmet omfatter psykoedukasjon, kognitiv restrukturering, eksponering og inkludering av foreldre. Opplæring, godkjenning av veiledere og godkjenning som Cool Kids-terapeut tilbys gratis av RKBU Vest. Programmet tilbys per i dag i Norge i kommunehelsetjenesten, skolehelsetjenesten og spesialisthelsetjenesten

Metode: Denne kunnskapsoppsummeringen bygger på et systematisk litteratursøk i databasene Embase, Medline og Psykinfo, NORART, Cochrane, Cristin, NORA, SCOPUS og SweMed. Det er også søkt i internasjonale kunnskapsdatabaser om evidens samt innhentet informasjon om tiltaket fra tiltakseier. Litteratursøk og annen innhentet informasjon ble gjennomgått for å identifisere nordiske effektstudier, internasjonale oppsummeringsstudier og eventuelt andre norske studier om tiltaket.

Resultater: Litteratursøket resulterte i 220 treff hvorav totalt 9 artikler ble inkludert, åtte nordiske effektstudier og en kunnskapsoppsummering. Cool Kids er detaljert beskrevet og er teoretisk forankret i kognitiv atferdsterapi, som har bred forskningsstøtte som behandling for angstlidelser. Studiene av Cool Kids holder god forskningsmetodisk kvalitet, med før, etter, og oppfølgingsmålinger, relevante og utprøvde måleinstrumenter og et multiinformant perspektiv i flertallet av studiene. Studiene ble gjennomført både i en klinisk gruppe og en gruppe som fikk indikert forebyggende (barn og ungdom som skårer over en terskelverdi på angst) tiltak. I flertallet av studiene var det en statistisk signifikant forskjell mellom intervensjonsgruppen (Cool Kids) og sammenligningsgruppen. I både en klinisk og i en indikert forebyggende kontekst  ble det påvist små til store effektstørrelser. Oppfølgingsstudier viser at effektnivået i stor grad opprettholdes over tid.

Konklusjon: Cool Kids er et evidensbasert tiltak som har et solid teoretisk fundament. Programmet er godt beskrevet. Resultater fra nordiske effektstudier tyder på at programmet kan bidra til reduksjon av angst og depresjonssymptom sammenlignet med vanlig behandling og effekten er vist å holde seg over tid for flere hoved utfallsmål. Cool Kids klassifiseres på evidensnivå 5 – Tiltak med sterk dokumentasjon på effekt.
Instance attack: an explanation-based vulnerability analysis framework against DNNs for malware detection
Authors: Sun Ruijin , Guo Shize , Xing Changyou , Duan Yexin , Yang Luming , Guo Xi , Pan Zhisong
Published: November 2023

Deep neural networks (DNNs) are increasingly being used in malware detection and their robustness has been widely discussed. Conventionally, the development of an adversarial example generation scheme for DNNs involves either detailed knowledge concerning the model (i.e., gradient-based methods) or a substantial quantity of data for training a surrogate model. However, under many real-world circumstances, neither of these resources is necessarily available. Our work introduces the concept of the instance-based attack, which is both interpretable and suitable for deployment in a black-box environment. In our approach, a specific binary instance and a malware classifier are utilized as input. By incorporating data augmentation strategies, sufficient data are generated to train a relatively simple and interpretable model. Our methodology involves providing explanations for the detection model, which entails displaying the weights assigned to different components of the specific binary. Through the analysis of these explanations, we discover that the data subsections have a significant impact on the identification of malware. In this study, a novel function preserving transformation algorithm designed specifically for data subsections is introduced. Our approach involves leveraging binary diversification techniques to neutralize the effects of the most heavily-weighted section, thus generating effective adversarial examples. Our algorithm can fool the DNNs in certain cases with a success rate of almost 100%. Instance attack exhibits superior performance compared to the state-of-the-art approach. Notably, our technique can be implemented in a black-box environment and the results can be verified utilizing domain knowledge. The model can help to improve the robustness of malware detectors.
Effects of a single bout of mobile action video game play on attentional networks
Authors: Wang Biye , Jiang Jiahui , Guo Wei
Published: November 2023

Background

Video game play has been linked to a range of cognitive advantages, and investigations in this domain have predominantly utilized cross-sectional designs or long-term training paradigms. Nevertheless, the specific effects of engaging in a single bout of video game play remain poorly understood. Consequently, the objective of this study is to examine the influence of a single session of mobile action video game (MAVG) play on attentional networks among college students.

Methods

Seventy-two nonvideo game players were assigned randomly into an MAVG and a control game group. Participants in the MAVG group engaged in a 60-minute session of an action video game played on mobile phones, while the control group played a mobile card game for the same duration. All participants completed the attentional network test (ANT), which assesses alerting, orienting, and executive control network efficiencies, before and after the intervention.

Results

The MAVG group had significantly improved alerting network efficiency following the intervention, compared to before (p < 0.05); the control game group did not. Neither executive control network efficiency nor orienting network efficiency were found to be improved by the intervention.

Conclusion

The present data demonstrated that a single bout of MAVG play can improve alerting network efficiency selectively in young-adult college students. MAVGs may be useful for promoting attentional function with the advantages of being accessible virtually any time and anywhere.
Jorge González: síntesis y bisagra de la música popular chilena
Authors: Larrea Melgarejo Felipe
Published: November 2023

El presente artículo tiene como objetivo plantear que la obra de Jorge González –considerando en esta a su música (canciones, álbumes y colaboraciones), su iconografía (videos, portadas de discos y estética visual en general), así como su discursividad y rol público–, o lo que llamaremos su locus de enunciación, produce una síntesis de la música popular chilena. Desde el disco La voz de los 80, González permite replantear la inscripción crítica de la historia de la música popular chilena, desde los años 60 hasta el presente (de ahí su carácter de «bisagra»), pero también al producir un encuentro singular entre la tradición lírica que cimentó la Nueva Canción Chilena con el primer movimiento de pop en Chile, que se llamó La Nueva Ola (en esto consistiría la «síntesis»). No obstante, esta lectura es efecto de los acontecimientos políticos ocurridos en Chile durante la revuelta de octubre del 2019 hasta el inicio de la pandemia, donde Jorge González se elevó como ícono y algunas de sus canciones fueron coreadas e interpretadas en las masivas protestas. Finalmente, este desplazamiento constituye una importante resistencia crítica a la cultura neoliberal, que trató de borrar, desde los años 80, el pasado musical anterior.

Poéticas Anarchivísticas Algoritmos que activan el patrimonio audiovisual
Authors: Hofman Matusevich Vanina Yael , Montero Valentina
Published: November 2023

En las últimas décadas la apropiación y construcción de archivos ha ido ganando terreno dentro de las prácticas artísticas, permitiendo visibilizar las políticas de archivo y los órdenes sociales a los que responden. Al mismo tiempo, han propuesto modos divergentes de activación de la memoria, problematizando creativamente las jerarquías y protocolos tradicionales, constituyéndose, así, en lo que podemos llamar estrategias anarchivísticas. Considerando que, en el seno de la cultura digital, la IA (Inteligencia Artificial) se ha vuelto clave en la gestión de la información, el presente artículo se pregunta de qué manera la utilización artística de esta tecnología contribuye a ofrecer nuevos enfoques para pensar el archivo, el patrimonio y la memoria. Dentro de la madeja de prácticas existentes, jalaremos de dos hilos: 1) por un lado, las tácticas apropiacionistas que operan activando nuevas lecturas sobre archivos ya constituidos; 2) por otro, aquellas que proponen la construcción de archivos nuevos, generalmente abarcando elementos dispersos u otrora ignorados. Ahondaremos en estas tendencias centrándonos en dos casos que abordan específicamente el patrimonio fílmico –Jan Bot y Oráculo de Capturas de Pantalla– identificando sus estrategias y características.
Irrupciones trans*temporales (a 50 años del golpe de Estado)
Authors: Carvajal Fernanda
Published: November 2023

Este artículo aborda la biografía de Marcia Alejandra, mujer transexual que inició su proceso medicalizado de «cambio de sexo» durante la Unidad Popular y logró su cambio legal de nombre en 1974, ya en dictadura. En el primer apartado, presento las nociones de cistemporalidad, trans*temporalidad y trans*historicidades como claves teórico-metodológicas. En la segunda parte, reconstruyo cómo la prensa abordó la historia de Marcia Alejandra desde una matriz cistemporal. Por contraste, en la tercera parte, retomo archivos informales reenfocando la biografía de Marcia desde una dimensión trans*temporal. A partir del análisis desde estas dos matrices temporales, interrogo qué sucede cuando ponemos en contacto lo travesti/trans* y la historicidad, a 50 años del golpe de Estado.
Retratos cinematográficos de Salvador Allende: tensiones entre tiempos, voces e imágenes
Authors: Véliz Mariano
Published: November 2023

El artículo se propone explorar tres documentales sobre Salvador Allende a partir del género del retrato: Compañero presidente (Miguel Littin, 1971), Salvador Allende (Patricio Guzmán, 2004) y Allende, mi abuelo Allende (Marcia Tambutti Allende, 2015). En cada uno de ellos se privilegia el estudio acerca del modo en el que se inscribe en la vasta tradición de este género recurriendo a textos teóricos dedicados a indagar en la historia y la actualidad del retrato. Al mismo tiempo, se busca problematizar la relevancia política de los retratos sobre Allende a partir de los diferentes contextos de producción y de las elecciones estéticas y políticas presentes en cada caso. A raíz de estas divergencias se proponen una serie de nociones: el «retrato de intervención» para dar cuenta del gesto emprendido por Littin, el «retrato fúnebre» para evaluar la particularidad del documental de Guzmán y el «retrato privado-público» para pensar las dimensiones más conflictivas del trabajo audiovisual de Tambutti Allende.

Este artículo explora el concepto de trauma colectivo y su aplicación en el contexto histórico y social de las sociedades latinoamericanas. La transferencia del término «trauma colectivo» desde el campo del conocimiento psicológico a la esfera social e histórica plantea preguntas sobre su legitimidad y marco conceptual. El estudio examina la fidelidad de esta transferencia conceptual y su relación con la comprensión psicoanalítica temprana de los fenómenos traumáticos. El contexto cultural europeo de finales del siglo xix y principios del siglo xx proporcionó la base para teorizar las consecuencias de experiencias intensas y violentas, lo que resultó en el concepto de «neurosis traumática», influenciado significativamente por el trabajo de Freud. El artículo discute la apropiación de herramientas psicoanalíticas en la crítica histórica y cultural para comprender eventos que desafían marcos tradicionales y la inteligibilidad social, como el Holocausto. La noción del trauma como una fuerza enigmática y recurrente en la experiencia histórica se explora a través del enfoque de los estudios del trauma. El artículo pone de relieve a destacados y destacadas académicas en este campo y su uso de conceptos psicoanalíticos, demostrando la preservación y aplicación significativa de estas nociones en la comprensión de fenómenos históricos y colectivos. Al acortar la brecha entre las experiencias psicológicas individuales y los traumas colectivos, los estudios del trauma ofrecen un enfoque único para interpretar y representar eventos que resisten las narrativas históricas tradicionales.

A tendência positiva registada nos últimos anos não supera e nem deve ignorar ou camuflar uma realidade preocupante e comprometedora socialmente, que é a subnutrição permanente. Esta se apresenta como um problema grave nos países lusófonos e implica que sejam tomadas medidas urgentes para o devido combate e a necessária prevenção. Diante dessa problemática, o presente artigo tem como escopo central apontar a importância da agricultura familiar e da agroecologia na produção de alimentos no Brasil e nos países Lusófonos da Comunidade dos Países de Língua Portuguesa, como uma estratégia mitigadora da problemática supracitada. Para tanto, esta pesquisa adotou o método procedimental bibliográfico com abordagem qualitativa em relação à problemática e estudo exploratório de natureza básica em relação aos objetivos pretendidos. No tocante a coleta de informações, adotou-se a técnica da revisão de literatura. Quanto aos resultados, conclui-se que nos países lusófonos estudados apesar do agricultor familiar representar a maioria nos trabalhos campesinos, este ainda enfrenta dificuldades no acesso a créditos e a tecnologias sendo de extrema importância a existência de políticas públicas voltadas para essa realidade. Por seu turno, a agroecologia é o instrumento que agrega à produção familiar, o aprimoramento e a melhoria do produto, respeitando as interações ecológicas e os conhecimentos tradicionais que são transmitidos entre as gerações.

La carga fiscal a la que se ven sometidas las personas naturales como resultado de las reformas tributarias implementadas por los gobiernos ha llevado a que estas recurran a prácticas ilegales para evadir sus responsabilidades fiscales, como la evasión y elusión del impuesto de renta. El objetivo de este análisis es comprender la normatividad en Colombia y Perú, cuestionar los privilegios que se otorgan y examinar la falta de formalización de empresas y personas. Como resultado se evidencia que ambos países sufren un déficit fiscal que intentan combatir con la imposición de más normas, lo que culmina afectando a las personas más vulnerables. A través de un ejercicio comparativo, se analizan los efectos de las reformas tributarias de cada gobierno, y también es importante conocer la opinión de los contribuyentes a través de una encuesta, que permite comprender mejor el dinamismo de estos sistemas tributarios similares.
Um estudo sobre a possível aplicação do modelo de imposto único sobre o consumo: o caso de Portugal

Published: November 2023

A adoção de um sistema de taxa única de IVA, nos Estados-Membros da União Europeia, tem sido uma questão controversa e complexa. Atualmente, a UE utiliza um sistema de várias taxas, concebido para acomodar as necessidades dos sectores e para promover a equidade na tributação do consumo. Este estudo procura avaliar a eficiência de diferentes modelos de impostos sobre o consumo - taxas diferenciadas versus uma taxa única. A investigação é baseada em dados oficiais, da Pordata, e abrange o período 1996-2022. A receita é avaliada através do modelo comum de IVA da União Europeia, com os devidos ajustamentos para o modelo de taxa única. Foram aplicados métodos quantitativos e teve como objetivo determinar qual dos modelos de IVA é mais eficiente na cobrança de receitas. O estudo analisa dois cenários para uma taxa única de IVA (17% e 21%). Os resultados apontam que o modelo de taxa única gera mais receitas em comparação com o atual sistema de taxas diferenciadas. O modelo de taxa de IVA de 21% é preferido em relação ao modelo de taxa de 17%, apesar de esta poder manter os níveis de receitas atuais e ainda aumentar o nível de cobrança. O estudo conclui que o modelo de taxa única é tecnicamente superior e mais eficiente do que o atual modelo prevalecente na UE, sugerindo que a oposição à sua adoção radica mais em considerações políticas do que técnicas.

The Brazilian legislation recognizes water springs and their surroundings as permanent preservation areas. In rural areas, many property owners do not follow the legislation, compromising their integrity and ecosystem functions. The objective of the study was to evaluate the environmental integrity of water springs in rural areas using the Environmental Impact Index of Springs and new indicators for planning, recovery, and preservation actions. The study was carried out in the northwest of the state of Rio Grande do Sul, Brazil, analyzing water springs with different use and conservation conditions. The Environmental Impact Index of Springs was evaluated and a detailed description of risks of pollution was carried out, called Characterization of the Surroundings of the Water Spring. The Environmental Impact Index of Springs shows that the preservation of springs in rural areas is compromised, mainly due to absence of vegetation, use by humans and animals, and easy accessibility. The Characterization of the Surroundings of the Water Spring pointed out that, even in the presence of vegetation, potential sources of contamination are found, showing the need for action plans to mitigate these effects. The joint use of these methodologies provides multidisciplinary and comprehensive subsidies to assess the integrity of these threatened ecosystems.

Authors: Justin Gradlin Roy , Maramreddy Revanth , Peesapati Sirisha , Mahajan Sachin
Published: November 2023

Introduction: The Fontan operation is a surgical technique used to treat cyanotic heart diseases with single ventricle physiology. Although it has undergone several modifications since its inception in 1971, it is still associated with significant morbidity and mortality. Aim: To examine the outcomes of the Fontan operation and identify various risk factors associated with it. Materials and Methods: This retrospective observational study was conducted at the Postgraduate Institute of Medical Education and Research (PGIMER) in Chandigarh, India from January 2014 to December 2017. All patients who underwent the Fontan operation at PGIMER were included in the study. The study analysed outcomes such as survival, arrhythmias, neurological complications, heart failure, cirrhosis, and Protein Losing Enteropathy (PLE) following the Fontan operation. Various risk factors that could potentially influence the outcome of the Fontan operation were assessed, including preoperative, intraoperative, and postoperative factors. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS) software, version 25.0. The Chi-square test was utilised to determine predictors of survival and other longterm outcomes, with a p-value of <0.05 considered statistically significant. Results: A total of 35 patients underwent the Fontan operation during the study period and completed five years of follow-up. Out of these, 28 were known to be alive at the last contact. There were six early deaths (less than one year). The overall oneyear and five-year survival rates from the time of the operation were 29 (83%) and 28 (80%), respectively. Graft thrombosis/ thromboembolism was observed in three cases (8.6%) and neurological complications in three cases (8.6%) during the early postoperative period. Arrhythmias in 6 cases (14%) were the most common late postoperative complication. Conclusion: The Fontan procedure is currently the best available palliative treatment for cyanotic heart diseases with single ventricle physiology. Patient selection is crucial in this procedure, as the presence of risk factors may adversely affect the outcome.

Authors: Setvaji Nisshitha Rao , Jain Ravindra Kumar
Published: November 2023

Introduction: Measurements of tooth crown dimensions and enamel thickness are useful guides for interproximal stripping procedures aimed at creating space. In borderline non extraction orthodontic treatment cases, interproximal stripping is performed to gain space. Intraoral periapical radiographs and bitewing radiographs are commonly used to determine Proximal Enamel Thickness (PET). Aim: To determine the predictability of using IOPA-based PET measurements for assessing real/anatomic PET. Materials and Methods: This was a single-centre, crosssectional study conducted at Saveetha Dental College and Hospital, Chennai, Tamil Nadu, India, between March 2022 and April 2022. Digital Intraoral Periapical Radiographs (IOPAs) of 40 premolar teeth with intact crown structures were obtained using the paralleling technique. The PET of both the mesial and distal sides of the same teeth was measured using Carestream Imaging software. Subsequently, the extracted teeth were sectioned and examined under a Stereomicroscope (SM), and PET measurements of the mesial and distal surfaces were obtained along the heights of contour using ImageJ analysis software. Pearson’s correlation, along with linear and polynomial regression analyses, was performed using International Business Machines (IBM) Statistical Package for Social Sciences (SPSS) software. Results: A low but significant positive correlation between the PET of the sectioned teeth and the PET measured from IOPAs was observed (p=0.002, R=0.55). A significant difference in PET between the two methods for both sides was noted (p<0.05). The mean distal enamel thickness was significantly greater than the mean mesial enamel thickness for both the IOPA and SM methods (p<0.05). A polynomial regression equation, Y=2.084- 1.234X+0.318X3 , was established to predict PET of the sectioned teeth (Y) based on PET measured from IOPAs (X). Conclusion: The present study establishes a correlation between the true PET of teeth measured using cut-sections and PET measured from IOPAs, which are readily available in clinical practice. A correlation coefficient was determined, and PET can be predicted using IOPAs, although not with absolute accuracy. Distal PET was found to be higher than mesial PET, with no significant difference in enamel thickness between the two sides.

Published: November 2023

This study aimed at investigating climate variability and its impact on livestock production across Nigeria. Observational data of monthly rainfall was obtained for a period of 42 years (1979 to 2021) from Nigerian Meteorological Agency (NiMET). The yearly animal production data was also obtained for a period of 10 years (2013 to 2022) from Federal Ministry of Agriculture and Natural resources. The data obtained was subjected to descriptive statistical analysis (mean, standard deviation and coefficient of variation) to show spread and variability; linear regression to show trend (changes with time); coefficient of correlation to show statistical relationship between the variables (rainfall and each of the animal production); revealing insights into changing precipitation patterns. Positive and negative correlations were identified, indicating how changes in rainfall influenced livestock output. And the significance of these correlations was determined through t-tests, shedding light on the strength of the relationship between rainfall and livestock production.

Understanding the consumer buying behavior of vermicompost in the Lucknow district of Uttar Pradesh is a critical aspect that needs to be understood in order to promote sustainable agriculture. This study aims to analyze the factors that influence the buying behavior of consumers towards vermicompost. The researcher employed a mixed-method approach, including both quantitative and qualitative data collection methods. The data was collected from primary as well as secondary sources of data. Secondary data was collected from published literature. In this study, we are going to find out the mindset of the consumer while purchasing vermicompost or bio-fertilizer. Nowadays, vermicompost is becoming increasingly popular because heavy chemical fertilizers are used to grow food grains, vegetables, and pulses, which has led to a lot of health issues in humans, with cancer being one of the major concerns. Apart from health issues, degrading soil health is a major problem faced by Indian farmers, and the only solution they have is vermicompost or bio-fertilizer. The researcher found that out of 100 respondents, only 40% were using vermicompost, while 60% were not using it. It has been noticed that the maximum number of respondents using vermicompost are marginal farmers or the urban population who are interested in kitchen or terrace gardening. The findings reveal that out of 100 respondents, only 40% were currently using vermicompost, indicating a relatively low adoption rate. Among the vermicompost users, 37% belonged to the marginal category of farmers with smaller land holdings. In contrast, the majority of non-users were large-scale farmers, citing higher costs as the primary reason for not adopting vermicompost. The study identifies key factors influencing consumer behavior. Awareness plays a significant role, with 20% of respondents reporting it as a motivation for purchasing or using vermicompost. Other factors include health consciousness (12.5%), involvement in vermicompost production (25%), nature-loving practices (17.5%), and the ease of application (12.5%).

The researcher concluded the research by recommending appropriate and useful strategies to promote the adoption of vermicompost among consumers in the Lucknow district of Uttar Pradesh

The study aimed to determine the conditions leading to maximum protease production using submerged fermentation and detecting the presence of protease genes in the bacteria. This is necessary to meet the increasing demand for protease enzymes in the industrial market. The ability of the bacterial isolate to produce protease enzymes was evaluated through primary screening. After that, morphological characterization, biochemical tests, and 16S rRNA analysis were done to identify the bacterial strain. To confirm the presence of the gene-encoding enzyme, the protease (npr) gene primer was amplified using a polymerase chain reaction. The pH, incubation duration, temperature, carbon, and nitrogen sources were studied. Others include metal ions, substrate concentration, and agitation speed. The bacterial strain has 100% similarity to Bacillus cereus A9, while the protease encoding gene was confirmed with positive bands of 951bp. The enzyme was optimally produced at 40 oC with a pH of 9 after 72 h incubation. Starch, gelatin, 1 % substrate concentration, 1mM K+, and agitation speed of 160 rpm fully supported protease production. The presence of the npr gene in the isolate was confirmed. Also, the optimization study reveals that Bacillus cereus LS23B can be used in large-scale protease production, which may be used in different biotechnological applications.

People in the inter-tidal zones of the Ganga-Brahmaputra-Meghana Delta regions are reliant on mangroves for food, medicine, protection, and livelihood. The present Anthropocene epoch has a deteriorated impact on people's societal, fiscal, and demography due to the climate change loss of agriculture and land use. The mangrove vegetation of Indian Sundarbans is declining in the South 24-Praganna district, West Bengal, the world’s largest estuarine forest, and the UNESCO Heritage, site.  

Remote sensing (RS) and geographic information systems (GIS) techniques were used to download data of the Landsat 8 OLI from USGS/GLOVIS of SOUTH 24 Parganas, West Bengal and analysed by ERDAS IMAGINE applications for speculation of the land use/land cover dynamics from the year 2015 to 2020. Ground truthing was conducted by site visits and compiled the medicinal use of plants to investigate the sustenance of SDG-3 and SDG-14.2 and SDG 14.5 of life in the Sundarbans.

The distribution of various mangrove species was identified in the core, buffer and manipulation zones of the Sundarbans Biosphere Reserve, their stratification along the cross-sections, zoning, and use as folk medicines. The research reveals mangrove vegetation is dwindling along the coasts of the South 24 Parganas. There is subsidence, emergence and submergence of land in the archipelago of nearshore Islands. The mangrove loss has been transformed into settlements or agricultural land. Recommendations are made to sustain the inter-tidal vegetation.

A field experiment was conducted during rabi, 2019-20 and 2020-21 at the PG experimental plot of the Department of Agronomy, BNCA to assess seed priming and moisture conservation measures on productivity and profitability of baby corn under the rainfed situation. The soil of the experimental site was acidic (pH 4.64), sandy loam in texture, medium in organic carbon (0.64%), low in available N (232.06 kg ha-1), P2O5 (13.84 kg ha-1) and K2O (115.27 kg ha-1). The experiment was laid out in factorial randomized block design with 4 levels of seed priming methods. S0: No priming; S1: Seed priming with 1% urea solution; S2: priming with 1% potash solution (MOP); S3: priming with 3 times diluted cow urine and 3 levels of soil moisture conservation measures viz. M0: No mulching; M1: use of bio mulch; M2: use of black polythene mulch. Results revealed that the highest and quickest seedling emergence (11.96 numbers m-2) was recorded under the treatment of seed priming with three times diluted cow urine which was at par with the treatment of seed priming with 1% urea and 1% KCl (MOP) solution. The total number of leaves m-2, total leaf area plant-1 and leaf area index (LAI) of baby corn were also changed significantly due to different moisture conservation measures but those parameters remain static due to different seed priming methods. The CGR (g m-2 day-1), RGR, (g g-1 day-1) and NAR (mg cm-1 day-1) of baby corn were also changed significantly due to different soil moisture conservation measures. The highest and most significant baby corn yield without husk(22.59 q ha-1) with 305.61 q ha-1 of green fodder yield along with harvest index (6.00), production efficiency (25.67 kg‑1 day-1 ha-1) and nutrient use productivity (9.41 kg‑1 ha-1 kg-1) were recorded under the treatment where black polythene mulching was used as soil moisture conservation measure.
