| 1 | Recent advances in assessment of soil erosion vulnerability in a watershed显示文摘Soil erosion is one of the most critical hazards adversely affecting both environment and economy.Assessment of the annual soil erosion rate provides information on soil erosion risk zones indicating the areas with high,severe and low risks.Modelling and prediction of soil erosion has a long history of more than seven decades.It becomes imperative to be familiar with the quantum of studies conducted and methods employed across the world to assess vulnerability of ecosystems to soil erosion to plan strategies for their conservation.There are several methods based on various factors like land use,soil quality,topography etc.available to assess the susceptibility of a region to soil loss.With time the gap in understanding of such models and their use around the world has increased.Numerous models for assessing soil erosion exist but there is a lack of knowledge on spatial distribution of the methods being used.Academic papers related to assessment of soil erosion vulnerability published during the past three decades(1991—2019)were reviewed.Total 160 studies were reviewed to understand advances in the methods used to assess soil erosion vulnerability worldwide,identification of the most popular methods and proportion of studies conducted in the fragile region of Himalayas.The results show that 18 different methods have mainly been used to assess soil erosion risk in different regions.These methods include statistical,physical,process based and empirical models.The use of few physical methods like ANSWERS and SHE has decreased with time while that of physical and process methods like RUSLE,SWAT,WEPP and PESERA has increased with time.The review highlighted that various models being used worldwide are based on their suitability to the region.It also brings to attention that few models like PESERA,EUROSEM and WEPP are mostly being used concentrated in a particular region.Models like PESERA and EPM are mostly used in European region and may be encouraged to estimate soil erosion in Himalayan region.The review also highlights lack of studies with inclusion of water quality as an important parameter while assessing soil erosion vulnerability in the region.The review suggests that in case of lack of data,various statistical methods like PCA,CF,FUZZY etc can be preferred for qualitative assessment over quantitative assessment Considering availability of accurate input,researchers need to attempt more methods and perform comparative studies to attain accurate results for assessing soil erosion vulnerability leading to strategizing soil conservation in fragile regions. | Shachi Pandey Parmanand Kumar Miodrag Zlatic Raman Nautiyal Vijender Pal Panwar | 2021 | International Soil and Water Conservation Research2021,9,3: | 2 |
| 2 | Isolation and Characterization of Phytoconstituents from the Stems of Ichnocarpus frutescens显示文摘AIM: To study the chemical constituents of the stem part of Ichnocarpus frutescens. METHODS: The ethanolic extract of Ichnocarpus frutescens was used for the isolation of chemical constituents with the help of silica gel G and Sephadex column chromatography and their structures were elucidated on the basis of spectral data and chemical methods. RESULTS: Five compounds were isolated and identified as n-butyl oleate (1), n-octyl tetracontane (2), tetratriacontadiene (3), n-nonadecanyl benzoate (4), and benzocosanyl arachidate (5). CONCLUSION: Compound 5 is new; and compounds 1-4 are isolated from genus Ichnocarpus frutescens for the first time. | Babita Aggarwal Mohd.Ali Vijender Singh Rajeev K.Singla | 2010 | 中国天然药物2010,8,6: | 2 |

| 10 | Using hybrid models to predict blood pressure reactivity to unsupported back based on anthropometric characteristics显示文摘目的:准确测量血压(BP)对于流行病学研究、筛查规划、调研研究和高血压相关病变(冠心病、中风、肾衰竭等)的早期诊断及预防有重要意义。被测者体位对于准确测量血压有重要影响。血压测量指南建议测试时被测者应在后背有支撑的情况下保持坐姿,以避免血压读数偏高。本文使用混杂模型预测血压对于无支撑后背的反应。创新点:本文考虑血压正常和高血压测试者的人体预测变量(如年龄、身高、体重、体块指数和上臂周长(AC)),使用基于PCA的前向逐步回归(PCA-SWR)、基于PCA的人工神经网络(PCA-ANN)、基于PCA的自适应神经模糊推理系统(PCA-ANFIS)和基于PCA的最小方差支持向量机(PCA-LS-SVM)等模型预测血压对无支撑后背的反应。方法:使用PCA消除人体预测变量间的多重共线性,并在原始数据集中选取主元(PC)。所选主元被输入至所建立预测模型用于建模及测试。结论:通过评估合适的统计指标(确定性系数、平均平方根误差、平均绝对百分比误差),得出较之其他模型,PCA-LS-SVM对于预测血压反应较有前景。此评估也展示了混杂模型在预测生物医学领域其他参数时的重要性和先进性。 | Gurmanik KAUR Ajat Shatru ARORA Vijender Kumar JAIN | 2015 | Frontiers of Information Technology & Electronic Engineering2015,16,6: | 1 |

| 13 | Evaluation of anti-inflammatory potential of leaf extracts of Skimmia anquetilia显示文摘Objective:To evaluate anti-inflammatory potential of leaf extract of Skimmia anquetilia by invitro and in-vivo anti-inflammatory models.Methods:Acute toxicity study was carried out to determine the toxicity level of different extract using acute toxic class method as described in Organization of Economic Co-operation and Development Guidelines No.423.Carrageenan(1% w/w) was administered and inflammation was induced in rat paw.The leaf extracts of Skimmia anquetilia were evaluated for anti-inflammatory activity by in-vitro human red blood cell(HRBC) membrane stabilization method and in-vivo carrangeenan-induced rat paw edema method. Results:The in-vitro membrane stabilizing test showed petroleum ether(PE),chloroform(CE), ethyl acetate(EE),methanol(ME) and aqueous extracts(AE) showed 49.44%,59.39%,60.15%,68.40% and 52.18%protection,respectively as compared to control groups.The in-vivo results of CE,EE and ME showed 58.20%.60.17%and 67.53%inhibition of inflammation after 6h administration of test drugs in albino rats.The potency of the leaf extracts of Skimmia anquetilia were compared with standard diclofenac(10 mg/kg) which showed 74.18%protection in in-vitro HRBC membrane stabilization test and 71.64%inhibition in in-vivo carrangeenan-induced rat paw edema model. The ME showed a dose dependent significant(P< 0.01) anti-inflammatory activity in human red blood cell membrane stabilization test and reduction of edema in carrageenan induced rat paw edema.Condusioiis:The present investigation has confirmed the anti-inflammatory activity of Skimmia anquetilia due to presence of bioactive phytoconstitutes for the first lime and provide the pharmacological evidence in favor of traditional claim of Skimmia anquetilia as an antiinflammatory agent. | Vijender Kumar Zulfiqar Ali Bhat Dinesh Kumar NA Khan IA Chashoo | 2012 | Asian Pacific Journal of Tropical Biomedicine2012,2,8: | 0 |
| 14 | Retrocaval ureter presenting at 6 years of age in a girl child e An extreme rarity显示文摘Retrocaval ureter is one of the very rare congenital anomalies.We report a case of retrocaval ureter in a 6-year-old girl who presented with right flank pain and hydronephrosis.The diagnosis was made on intravenous urography which showed typical“J”shape deformity in the proximal dilated ureter with moderate hydronephrosis.CT scan delineated the course of ureter.The patient was operated and findings were confirmed.The ureter was transected near the pelvis and a pyeloureteric anastomosis with pre-caval transposition of the ureter was performed and the patient was discharged in fair health. | Pradeep Kajal Kamal Rattan Vijender Sangwan Namita Bhutani | 2016 | Asian Journal of Urology2016,3,2: | 0 |
