| 1 | Effects of 42-year long-term fertilizer management on soil phosphorus availability, fractionation,adsorption–desorption isotherm and plant uptake in flooded tropical rice显示文摘Soil phosphorus(P) fractionation, adsorption, and desorption isotherm, and rice yield and P uptake were investigated in flooded tropical rice(Oryza sativa L.) following 42-year fertilizer and manure application. The treatments included low-input [unfertilized control without N, P, or K(C0N0)], farmyard manure(FYM)(C1N0), NP(C0NP), NPK(C0NPK), FYM + NP(C1NP), and high-input treatment, FYM + NPK(C1NPK). Grain yield was increased significantly by 74%over the control under the combined application of FYM + NPK. However, under low- and high-input treatments, yield as well as P uptake was maintained at constant levels for 35 years.During the same period, high yield levels and P uptake were maintained under the C0 NP, C0 NPK,and C1 NPK treatments. These are unique characteristics of a tropical flooded ecosystem, which is a self-sustaining system for rice production. The Fe–P fraction was highest compared to the Ca–P and Al–P fractions after 42 years of fertilizer application and was significantly higher under FYM + NPK treatment. The P adsorption capacity of soil was highest under the low-input treatment and lowest under long-term balanced fertilization(FYM + NPK). In contrast, P desorption capacity was highest under NPK and lowest in the control treatment. Long-term balanced fertilization in the form of FYM + NPK for 42 years lowered the bonding energy and adsorption capacity for P in soil but increased its desorption potential, increasing P availability to the plant and leading to higher P uptake and yield maintenance. | Pratap Bhattacharyya Amaresh Kumar Nayak Mohammad Shahid Rahul Tripathi Sangita Mohanty Anjani Kumar Rajagounder Raja Bipin Bihari Panda Banwari Lal Priyanka Gautam Chinmaya Kumar Swain Koushik Singha Roy Pradeep Kumar Dash | 2015 | The Crop Journal2015,3,5: | 5 |
| 2 | 基于遥感影像的甘达基流域博卡拉和巴拉普尔的土地利用变化及其驱动力研究(英文)显示文摘城市扩张是反映经济增长的重要指标,但随意的城市扩张也带来了严重的社会经济问题、环境问题以及城市土地管理问题。在这个背景下,理解城市扩张的过程对于指导城市的可持续增长具有重要意义。本研究采用基于遥感影像的监督分类方法,分析了甘达基流域内的两个大城市—博卡拉和巴拉普尔1990–2018年的城市用地变化。结果表明:在过去的28年,博卡拉和巴拉普尔的城市面积分别显著扩张了300%和近500%。人口增长、城市基础设施和便利的生活方式引起周边地区向城市的人口迁移,是造成本研究区城市扩张的主要原因。除此之外,不断变化的城市定义和城市边界的扩张是造成城市快速扩张的关键因素。由于上述两个城市拥有高水平的商业活动以及现代化的设施,未来城市规模可能继续扩大。应当通过城市规划和政策减少随意的城市扩张,从而实现城市的可持续发展。 | Raju RAI 张镱锂 Basanta PAUDEL Narendra Raj KHANAL Bipin Kumar ACHARYA | 2020 | Journal of Resources and Ecology2020,11,1: | 3 |
| 3 | 表面缺陷对硅橡胶密封性能的影响规律研究显示文摘采用有限元方法研究金属表面凸起缺陷对硅橡胶密封性能的影响规律。基于ABAQUS软件,建立密封接触过程有限元模型。重点分析表面凸起的高度、半径和位置对密封性能的影响。结果表明:表面凸起缺陷对密封性能影响显著;高度和位置对接触压力和接触面积影响较大,凸起的高度越大、距离接触压力的峰值位置越近时,越容易发生泄漏;而凸起半径对密封性能的影响相对较小。 | 吴健 董吉义 Bipin Kumar Gond 王友善 粟本龙 崔志博 | 2018 | 橡胶工业2018,65,5: | 3 |

| 11 | 基于CAMEL模型的尼泊尔银行和纳比尔银行的比较绩效分析显示文摘银行是被政府许可的一种金融机构。它接受公众存款,贷款给需要钱的民众、实业家或商户。它把分散在经济领域的资金融通到生产部门,从而促进经济的全面发展。分析银行业绩效很大程度上是检验宏观经济表现的一种有效的指标和措施。银行业的绩效表现被认为是经济活动的替代品,健全的银行系统是经济、社会和产业增长的基石。商业银行绩效评价研究常常和银行能够在多大程度上利用它的资产、股东权益和负债、收支等有关。因此许多研究人员、学者、政策制定者用CAMEL来对银行绩效进行评估。CAMEL是一种非常有用的、检验银行安全性和稳固性的分析工具,可能帮助减轻导致银行破产的潜在风险。 | Prakash Kumar Bipin 孙雨晗 | 2019 | 价值工程2019,38,5: | 0 |
| 12 | Clinical Efficacy of Inhaled Nitric Oxide in Preventing the Progression of Moderate to Severe COVID-19 and Its Correlation to Viral Clearance:Results of a Pilot Study显示文摘Hypoxic patients with coronavirus disease 2019(COVID-19)are at high risk of adverse outcomes.Inhaled nitric oxide(iNO)has shown anti-viral and immunomodulatory effects in vitro.However,in vivo evidence of efficacy in hypoxic COVID-19 is sparse.This open label feasibility study was conducted at a single referral center in South India and evaluated the effectiveness of repurposed iNO in improving clinical outcomes in COVID-19 and its correlation with viral clearance.We recruited hypoxemic COVID-19 patients and allocated them into treatment(iNO)and control groups(1:1).Viral clearance on day 5 favored the treatment group(100%vs 72%,P<0.01).The speed of viral clearance as adjudged by normalized longitudinal cycle threshold(Ct)values was positively impacted in the treatment group.The proportion of patients who attained clinical improvement,defined as a≥2-point change on the World Health Organization ordinal scale,was higher in the iNO cohort(n=11,79%)as compared to the control group(n=4,36%)(odds ratio 6.42,95%confidence interval 1.09–37.73,P=0.032).The proportion of patients progressing to mechanical ventilation in the control group(4/11)was significantly higher than in the treatment group(0/14).The all-cause 28-day mortality was significantly different among the study arms,with 36%(4/11)of the patients dying in the control group while none died in the treatment group.The numbers needed to treat to prevent an additional poor outcome of death was estimated to be 2.8.Our study demonstrates the putative role of repurposed iNO in hypoxemic COVID-19 patients and calls for extended validation. | Merlin Moni Thushara Madathil Dipu T.Sathyapalan Veena Menon Georg Gutjahr Fabia Edathadathil Deepthi Sureshkumar Preetha Prasanna Soumya Jose Roshni Jerome Ajai Krishnan Indulekha C.L.Pillai Geetha Kumar Bipin Nair Victor Nizet Aveek Jayant | 2022 | Infectious Microbes & Diseases2022,4,1: | 0 |
| 13 | 气候变化对喜马拉雅中部甘达基河流域濒危物种的影响预测显示文摘甘达基河流域位于喜马拉雅山脉中部,是众多濒危野生物种的重要栖息地。然而气候变化使该流域的生态环境变得愈发脆弱。本研究利用最大熵物种分布模型(Max Ent)评估气候变化对喜马拉雅黑熊(Ursus thibetanus laniger)和印度花豹(Panthera pardus fusca)等濒危物种空间分布变化的潜在影响。研究基于物种出没地点、生物气候和地形(海拔、坡度和坡向)等数据拟合模拟并预测物种在目前与未来的潜在分布情况。研究结果显示,目前喜马拉雅黑熊的高度适宜区面积约为1642 km^(2),占流域面积的5.01%,预计至2050年,其高度适宜区面积在甘达基河流域内将会增加约51 km^(2);印度花豹的高度适宜区面积约为3999 km^(2),占流域面积的12.19%,预计至2050年可能会增加到4806 km^(2)。喜马拉雅黑熊的栖息地面积可能会在研究区域的东部(伯塞里、塔托潘尼和班塞以北)增加,而在东部(颂当、切坎帕)、西部(布尔提邦和波邦)和北部(桑波切、玛南、切坎帕)减少;印度花豹的栖息地面积则将在研究区域东南部(班塞)、西部部分地区(赫里乔尔和桑迪哈克北部)和西北部(桑波切)增加,而在研究区域的东部、南部和其他西部地区减少。研究同时指出,海拔、Bio 15(季节性降水变化)和Bio 16(最湿润季度降水量)等环境因素对喜马拉雅黑熊的栖息地变化影响较大,而Bio 13(最湿润月降水量)和Bio 15(季节性降水变化)对印度花豹的栖息地变化影响较大。总之,这两个物种的栖息地在不同海拔下均会受到气候变化的影响,需要加强对该区域内濒危物种的保护力度。 | Raju RAI 张镱锂 刘林山 Paras Bikram SINGH Basanta PAUDEL Bipin Kumar ACHARYA Narendra Raj KHANAL | 2022 | Journal of Resources and Ecology2022,13,2: | 0 |

| 15 | 扭带式换热器水热关联的机器学习辅助建模显示文摘本文介绍了机器学习(ML)算法在带扭带插件的换热器传热关联(如努塞尔数和摩擦系数)建模中的应用.采用换热器在不同雷诺数(Re)、扭转比(t)、穿孔率(p)和不同扭带数(n)下的实验数据进行相关建模.在数据驱动的代理建模中使用了三种机器学习算法:多项式回归(PR)、随机森林(RF)和人工神经网络(ANN).为了保证模型的通用性,对ML模型的超参数进行了优化,分析了不同ML算法的性能参数(如R 2和MAE).结果表明,在不同的测试数据集上,人工神经网络对传热系数的预测优于PR和RF的预测.基于本文分析内容,对未来数据驱动的传热关联建模工作和类似研究提出了建议. | Jyoti Prakash Panda Bipin Kumar Anil Kumar Patil Manoj Kumar Ravi Kumar | 2023 | Acta Mechanica Sinica2023,39,1: | 0 |
| 16 | ON THE VOLUME OF FLUID METHOD FOR MULTIPHASE FLUID FLOW SIMULATION显示文摘Numerical study of multiphase fluid flows require mathematical methods for distinguishing interface between two fluids.The volume of fluid(VOF)method is one of such method which takes care of fluid shape in a local domain and reconstructs the interface from volume fraction of one fluid.Maintaining sharp interface during reconstruction is a challenging task and geometrical approach of VOF method better suits for incompressible fluids.This paper provides a complete mathematical discussion of extended form of VOF method using a approach known as piecewise linear interface calculation(PLIC).An analytical relation between volume fraction and interface position has been explored with the help of primitive geometrical shapes.The method with this analytical relation has been applied to multiphase fluid flow benchmark problems and found to be in good agreement. | BIPIN KUMAR MARTIN CRANE YAN DELAURE | 2013 | International Journal of Modeling, Simulation, and Scientific Computing2013,4,2: | 0 |
