Triggers include natural disasters like earthquakes and floods, as well as accidents, attacks and explosions. Reinforced concrete flat slab structures, which are eminent for their architectural flexibility and have larger spans, are particularly susceptible to disproportionate collapse, due to the lack of floor beams, which can redistribute loads after a column failure, unlike moment frame buildings. This research examines how multi-story reinforced concrete flat slab buildings behave, under prescribed gravity load combinations, compared to conventional framed buildings. The effects of removing columns at specified locations from an intermediate floor of the multistorey building are also examined. However, this investigation covers both the column removal approaches to check a possibility of disproportionate collapse which are; static removal and dynamic instantaneous removal. Furthermore, the research also assesses the efficacy of perimeter beams, in minimising the risk of gradual collapse in flat slab structures, by scrutinising their ability to reduce joint displacement, chord rotation, and demand capacity ratio. \u0000ETABS v18 was used to analyze all the 18 models. The findings revealed that buildings are more prone to progressive collapse when corner columns are removed, as opposed to edge and interior columns, due to higher Demand-Capacity Ratios (DCR) and joint displacement. In comparison to dynamic analysis, the static evaluation exhibited greater DCR values and vertical joint displacement. Furthermore, since they have a more efficient load redistribution mechanism, traditional framed structures performed better than flat slab models. The simulations additionally indicated that, adding edge perimeter beams, substantially lowered the possibility of progressive collapse in flat slab structures. Moreover, the tested flat slab building models, with and without perimeter beams showed no indications of progressive collapse, when specified columns were removed from the intermediate floors, since the DCR values of the crucial columns stayed within the permissible range of 2.0. In conclusion, structures built in compliance with IS 1893:2016 code and designed to withstand seismic loads demonstrate stronger resistance against significant damage, brought about by column failures.","PeriodicalId":16985,"journal":{"name":"Journal of Scientific Research and Reports","volume":"16 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141646692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ideally, all emitters should discharge equal amounts of water, but variations occur due to hydraulic and manufacturing factors. This study established the pressure-discharge relationship curve and determined emitter flow variation caused by the hydraulic and the manufacturer’s coefficients of variation for 2 and 4 lph inline emitters. The power exponent and constant of the pressure-discharge curve were determined by measuring the emitter flow rates at operating pressures ranging from 0.2 to 3.0 kg/cm². The emitter flow rates of 100 emitters were measured at an operating pressure of 1.0 kg/cm² to determine the manufacturing coefficient (Vm) and emitter flow variation (qvar(m)). The discharge exponent was found to be 0.46 for both emitter flow rates, with proportionality constants of 0.692 for 2 lph and 1.387 for 4 lph emitters respectively. The results showed a strong correlation between pressure and flow rate, with RMSE values of 0.51 and 0.34 lph, and coefficients of determination of 0.988 and 0.991 for 2 and 4 lph emitters, respectively. High manufacturing precision was indicated by low Vm values of 0.0491 for 2 lph and 0.055 for 4 lph emitters, while qvar(m) values were 0.261 for 2 lph and 0.283 for 4 lph emitters. Total coefficient of variation (Vq) values were 0.1 for 2 lph and 0.14 for 4 lph emitters, with total emitter flow variations (qvar) of 0.29 for 2 lph and 0.39 for 4 lph emitters. The study established the pressure-discharge curve for inline drip irrigation systems, emphasizing the critical relationship between pressure and flow rate. The derived chart from pressure discharge relationship is a valuable tool for estimating emitter flow variation due to hydraulic variation within the same subunit. Precise manufacturing and effective management of hydraulic variations are essential for ensuring uniform water distribution, optimizing drip irrigation systems, and ultimately enhancing crop yield and resource utilization.","PeriodicalId":16985,"journal":{"name":"Journal of Scientific Research and Reports","volume":"44 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141644818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

February month shows the highest decrease in the values (ZMK -2.33 to -1.72, p<0.05). Winter and summer shows highly significant decreasing trends, Manvi showing the maximum decreasing trend in winter (ZMK = -2.57, p < 0.01) and Raichur in summer (ZMK = -2.89, p < 0.01). Sen’s slope estimates show average decrease of -0.18 to -0.15 mm/month in winter and an average value of -0.246 mm/month in summer. For monsoon and post monsoon, the trends are weaker and not significant ranging from -0.05 to 0.03 mm/month. Yearly changes reveal slightly negative values (-0.12 to -0.04 mm/month). Spatial interpolation of the ETo changes is done using ArcGIS’s inverse distance weighting (IDW) method to show the regional differences. An increase in air temperature results in the rise in the trends in some months while, a decline in wind speed may be reason in other region. These findings are useful in understanding the ETo dynamics in the region and its relation to water and agriculture.

Bread wheat possesses remarkable adaptability to diverse climates and soil types. However, heat stress, exacerbated by global climate change, poses a significant threat to wheat production. Developing heat-tolerant wheat varieties is essential to ensuring food security. This study identified to identify genetic variance in heat tolerance through the Line × Tester analysis, a breeding tool that evaluates the combining ability of parental lines. The experimental material comprised 16 crosses derived from four high-yielding lines and four heat-tolerant testers. These were cultivated in Pantnagar, India, under late-sown conditions to replicate heat stress. Agronomic traits such as plant height, tiller number, grains per spike, days to maturity, and grain yield were evaluated. Analysis of variance (ANOVA) was used to estimate general combining ability (GCA) and specific combining ability (SCA), providing insights into additive and non-additive genetic variances. Results indicated significant genetic variability among genotypes, with substantial non-additive genetic components influencing most traits. Plant height, for instance, demonstrated significant GCA and SCA variances, with SCA effects being more pronounced. Similarly, traits like the number of tillers per plant and grains per spike were predominantly controlled by non-additive genetic factors. The study revealed that hybrid combinations significantly influenced growth and yield traits, underscoring the importance of both GCA and SCA in breeding programs. The significant Line × Tester interactions suggest that specific combinations of parental lines and testers are crucial for achieving superior phenotypes. This study supports the notion that both additive and non-additive genetic effects are vital for crop improvement under heat stress, providing a robust foundation for future breeding programs aimed at enhancing wheat resilience to increasing temperatures.","PeriodicalId":16985,"journal":{"name":"Journal of Scientific Research and Reports","volume":"17 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141653889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During investigations of the pathogen, it was found that there was a considerable variation in the conidial characteristics of Stemphylium species compared to the available literature. Stemphylium vesicarium was invariably found associated with typically blighted onion leaves throughout the growing period (82.75 per cent in January to 77.40 per cent in February), though its relative occurrence declined slightly in March (49.15 per cent) and April (37.75 per cent).

This review explores the feasibility, implementation, and benefits of biogas technology in hilly regions, where unique geographical and climatic conditions present both opportunities and challenges. The paper discusses types of feedstock, biogas plant designs, socio-economic impacts, and policy frameworks pertinent to hilly areas, supplemented by case studies from various regions worldwide. Through a comprehensive analysis, this review aims to provide insights into the potential of biogas technology to contribute to sustainable development in hilly terrains. Biogas, in its raw form, that is without any purification can be used as clean cooking fuel like LPG, lighting, motive power and generation of electricity. It can be used in diesel engines to substitute diesel up to 80% and up to 100% replacement of diesel by using 100% Biogas Engines. Further, Biogas can be purified and upgraded up to 98% purity of methane content to make it suitable to be used as a green and clean fuel for transportation or filling in cylinders at high pressure of 250 bar or so and called as Compressed Bio-Gas (CBG).","PeriodicalId":16985,"journal":{"name":"Journal of Scientific Research and Reports","volume":"67 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141658496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
