2Significant increase in HBV, HCV, HIV and syphilis infections among blood donors in West Bengal, Eastern India 2004-2005: Exploratory screening reveals high frequency of occult HBV infection显示文摘AIM: To evaluate the prevalence of markers of hepatitis B virus (HBV) and hepatitis C virus (HCV) and human immunodeficiency virus (HIV) among blood donors in Kolkata, Eastern India for two consecutive years and to conduct a pilot study to explore the presence of HBV DNA among hepatitis B surface antigen (HBsAg) negative but anti-HBc positive blood donors. METHODS: Seroprevalence of HBsAg, anti-HCV and anti-HIV was studied among 113 051 and 106 695 voluntary blood donors screened in 2004 and 2005, respectively. Moreover, a pilot study on 1027 HBsAg negative donors was carried out for evaluating the presence of HBV DNA by PCR on HBsAg negative/anti- HBc positive donors. RESULTS: A statistically significant increase in the prevalence of HBV (1448 vs 1768, P < 0.001), HIV (262 vs 374, P < 0.001), HCV (314 vs 372, P = 0.003) and syphilis (772 vs 853, P = 0.001) infections was noted among blood donors of Kolkata West Bengal in 2005 as compared to 2004. Moreover, the exploratory study on 1027 HBsAg negative donors revealed that 188 (18.3%)of them were anti-HBc positive out of which 21% were positive for HBV DNA. CONCLUSION: The findings of this study underscore the significantly increasing endemicity of hepatitis viruses, syphilis and HIV among the voluntary blood donors of our community. The pilot study indicates a high rate of prevalence of HBV DNA among HBsAg negative/anti-HBc positive donors and thus emphasizes the need for a more sensitive and stringent screening algorithm for blood donations.Prasun Bhattacharya Partha Kumar Chandra Sibnarayan Datta Arup Banerjee Subhashish Chakraborty Krishnan Rajendran Subir Kumar Basu Sujit Kumar Bhattacharya Runu Chakravarty 2007World Journal of Gastroenterology2007,13,27:9
3动态统计预报模型及其在2008奥帆赛风场预报中的应用显示文摘通过比较各种MOS方法在短期风速风向预报中的优劣,建立了一种基于动力统计预报模型和数值预报结果进行优化集合的动态MOS预报方法。在2005—2007年8月份风速的后报检验中,集合MOS预报可以将数值模式MM5的风速预报绝对平均误差减少30%以上。对风向预报的准确性也有明显的改进。从2008年8月10日至21日奥帆赛期间浮标A、B、C和D的检验结果来看,观测风速不大于6m.s-1的情况下,MOS平均绝对误差仅为1.1m.s-1,比MM5相应的预报误差(1.45m.s-1)减小24%。值得指出的是MM5对8月17至18日和21日的大尺度大风天气过程预报相对准确,而统计模型对这三天的风速快速加速过程反应迟缓。MOS的风向预报与MM5没有本质上的差别。两者的平均绝对误差总的来说相差小于10°,对预报员的风向预报决策影响没有明显的区别。林行 马艳 杨育强 谢立安 Sujit Ghosh 刘斌 苗卉平 高荣珍 孙桂平 2008气象2008,34,S1:7
4Earthquake swarms near eastern Himalayan Syntaxis along Jiali Fault in Tibet:A seismotectonic appraisal显示文摘The seismotectonic characteristics of ten repeated earthquake swarm sequence within a seismic cluster along Jiali Fault in eastern Himalayan Syntaxis(EHS) have been analysed.The swarms are spatially disposed in and around Yigong Lake(a natural lake formed by blocking of Yigong River by landslide) and are characterized by low magnitude,crustal events with low to moderate b values.Ms:mb discriminant functions though indicate anomalous nature of the earthquakes within swarm but are considered as natural events that occurred under condition of high apparent stress and stress gradients.Composite fault plane solutions of selected swarms indicate strike-slip sense of shear on fault planes;solution parameters show low plunging compression and tensional axes along NW-SE and NE-SW respectively with causative fault plane oriented ENE-WSW.dipping steeply towards south or north.The fault plane is in excellent agreement with the disposition and tectonic movement registered by right lateral Jiali Fault.The process of pore pressure perturbation and resultant 'r—t plot' with modelled diffusivity(D = 0.12 m^2/s) relates the diffusion of pore pressure to seismic sequence in a fractured poro-elastic fluid saturated medium at average crustal depth of 15-20 km.The low diffusivity depicts a highly fractured interconnected medium that is generated due to high stress activity near the eastern syntaxial bent of Himalaya.It is proposed that hydro fracturing with respect to periodic pore pressure variations is responsible for generation of swarms in the region.The fluid pressure generated due to shearing and infiltrations of surface water within dilated seismogenic fault(Jiali Fault) are causative factors.Basab Mukhopadhyay Sujit Dasgupta 2015Geoscience Frontiers2015,6,5:6

8Applying deep learning and benchmark machine learning algorithms for landslide susceptibility modelling in Rorachu river basin of Sikkim Himalaya, India显示文摘Landslide is considered as one of the most severe threats to human life and property in the hilly areas of the world.The number of landslides and the level of damage across the globe has been increasing over time.Therefore,landslide management is essential to maintain the natural and socio-economic dynamics of the hilly region.Rorachu river basin is one of the most landslide-prone areas of the Sikkim selected for the present study.The prime goal of the study is to prepare landslide susceptibility maps(LSMs)using computer-based advanced machine learning techniques and compare the performance of the models.To properly understand the existing spatial relation with the landslide,twenty factors,including triggering and causative factors,were selected.A deep learning algorithm viz.convolutional neural network model(CNN)and three popular machine learning techniques,i.e.,random forest model(RF),artificial neural network model(ANN),and bagging model,were employed to prepare the LSMs.Two separate datasets including training and validation were designed by randomly taken landslide and nonlandslide points.A ratio of 70:30 was considered for the selection of both training and validation points.Multicollinearity was assessed by tolerance and variance inflation factor,and the role of individual conditioning factors was estimated using information gain ratio.The result reveals that there is no severe multicollinearity among the landslide conditioning factors,and the triggering factor rainfall appeared as the leading cause of the landslide.Based on the final prediction values of each model,LSM was constructed and successfully portioned into five distinct classes,like very low,low,moderate,high,and very high susceptibility.The susceptibility class-wise distribution of landslides shows that more than 90%of the landslide area falls under higher landslide susceptibility grades.The precision of models was examined using the area under the curve(AUC)of the receiver operating characteristics(ROC)curve and statistical methods like root mean square error(RMSE)and mean absolute error(MAE).In both datasets(training and validation),the CNN model achieved the maximum AUC value of 0.903 and 0.939,respectively.The lowest value of RMSE and MAE also reveals the better performance of the CNN model.So,it can be concluded that all the models have performed well,but the CNN model has outperformed the other models in terms of precision.Kanu Mandal Sunil Saha Sujit Mandal 2021Geoscience Frontiers2021,12,5:4

11Stabilization of expansive soils using chemical additives: A review显示文摘Volume instability of expansive soils due to moisture fluctuations is often disastrous,causing severe damages and distortions in the supported structures.It is,therefore,necessary to adequately improve the performance of such soils that they can favorably fulfil the post-construction stability requirements.This can be achieved through chemical stabilization using additives such as lime,cement and fly ash.In this paper,suitability of such additives under various conditions and their mechanisms are reviewed in detail.It is observed that the stabilization process primarily involves hydration,cation exchange,flocculation and pozzolanic reactions.The degree of stabilization is controlled by several factors such as additive type,additive content,soil type,soil mineralogy,curing period,curing temperature,delay in compaction,pH of soil matrix,and molding water content,including presence of nano-silica,organic matter and sulfate compounds.Provision of nano-silica not only improves soil packing but also accelerates the pozzolanic reaction.However,presence of deleterious compounds such as sulfate or organic matter can turn the treated soils unfavorable at times even worser than the unstabilized ones.Dharmendra Barman Sujit Kumar Dash 2022Journal of Rock Mechanics and Geotechnical Engineering2022,14,4:3
12Suspended load in flows on erodible bed显示文摘Steady state suspended-load of sediment transported in flow over erodible beds usually is treated by the advection-diffusion approach, though in recent years, it is being treated as a two-phase flow phenomenon incorporating kinetics of sediment particles. Among the advection-diffusion approaches, Rouse's equation is the well-known, although a number of researchers in later periods have attempted to improve it by modifying the mixing length concept taking into account other aspects. In this paper, the advection-diffusion approach and associated logarithmic law of flow velocity are revisited. It is concluded from the logarithmic law that the Reynolds shear stress is a linear function of height above the bed, which reduces to bed shear stress in the case of a long horizontal channel. As a consequence, it is shown that the volumetric concentration of sediment is best approximated by the sum of two power laws of height above the bed. An equation is derived for the suspended-load transport rate in terms of elementary functions.Sujit K. BOSE Subhasish DEY 2009International Journal of Sediment Research2009,24,3:3
13Thermal analysis of a constructal T-shaped porous fin with simultaneous heat and mass transfer显示文摘The present work establishes an analytical model for computing the temperature distribution, fin efficiency and optimum design parameters of a constructal T-shaped porous fin operating in fully wet condition. For more practical results, this study considers a cubic polynomial relationship between the humidity ratio of saturated air and the corresponding fin surface temperature. The temperature distribution has been determined by solving the highly non-linear governing equations using a semi-analytical transformation technique called Differential Transform Method. A comparison of the results with that of a numerical model shows that this transformation method is a very efficient and convenient tool for solution of non-linear problems. The effects of various geometric, thermo-physical and psychometric parameters on the temperature distribution, fin efficiency and optimum design condition have been investigated. Also, a comparison has been presented between solid and porous fins and the results point out that by selecting an appropriate value of porosity, the heat transfer rate can be increased than the corresponding solid fin.Saheera Azmi Hazarika Tuhin Deshamukhya Dipankar Bhanja Sujit Nath 2017Chinese Journal of Chemical Engineering2017,25,9:3
14Functional outcome of tibial fracture with acute compartment syndrome and correlation to deep posterior compartment pressure显示文摘AIM To measure single baseline deep posterior compartment pressure in tibial fracture complicated by acute compartment syndrome(ACS) and to correlate it with functional outcome.METHODS Thirty-two tibial fractures with ACS were evaluated clinically and the deep posterior compartment pressure was measured. Urgent fasciotomy was needed in 30 patients. Definite surgical fixation was performed either primarily or once fasciotomy wound was healthy. The patients were followed up at 3 mo, 6 mo and one year. At one year, the functional outcome [lower extremity functional scale(LEFS)] and complications were assessed.RESULTS Three limbs were amputated. In remaining 29 patients, the average times for clinical and radiological union were 25.2 ± 10.9 wk(10 to 54 wk) and 23.8 ± 9.2 wk(12 to 52 wk) respectively. Nine patients had delayed union and 2 had nonunion who needed bone grafting to augment healing. Most common complaint at follow up was ankle stiffness(76%) that caused difficulty in walking,running and squatting. Of 21 patients who had paralysis at diagnosis, 13(62%) did not recover and additional five patients developed paralysis at follow-up. On LEFS evaluation, there were 14 patients(48.3%) with severe disability, 10 patients(34.5%) with moderate disability and 5 patients(17.2%) with minimal disability. The mean pressures in patients with minimal disability, moderate disability and severe disability were 37.8, 48.4 and 58.79 mmH g respectively(P < 0.001).CONCLUSION ACS in tibial fractures causes severe functional disability in majority of patients. These patients are prone for delayed union and nonunion; however, long term disability is mainly because of severe soft tissue contracture. Intracompartmental pressure(ICP) correlates with functional disability; patients with relatively high ICP are prone for poor functional outcome.Saumitra Goyal Monappa A Naik Sujit Kumar Tripathy Sharath K Rao 2017World Journal of Orthopedics2017,8,5:3
15Association of vitamin D and knee osteoarthritis in younger individuals显示文摘BACKGROUND The incidence of primary osteoarthritis knee is gradually increasing among young individuals.The increasing prevalence of obesity,sedentary lifestyle,sporting activity,and vitamin D deficiency(VDD)has been hypothesized for this shifting disease trend.This study was designed to look for the association of serum vitamin D among these young arthritic patients.AIM To look for the association of serum vitamin D in younger knee osteoarthritis(KOA)patients.METHODS In a 2-year observational study,146 non-obese KOA patients of 35-60 years were evaluated clinically(Knee injury and Osteoarthritis Outcome Score,KOOS)and radiologically(Kellegren-Lawrence stage,KL).The serum 25(OH)D level of these patients and 146 normal healthy individuals of same age group were estimated.RESULTS Both the groups were comparable in terms of age and sex.The average serum 25(OH)D level in healthy individuals and KOA patients was 45.83 ng/mL and 34.58 ng/mL,respectively(P<0.001).Inadequate serum 25(OH)D level(<30 ng/mL)was found in 46.57%of KOA patients and 24%of normal healthy participants indicating a significant positive association(odds ratio 2.77,95%CI:1.67-4.54,P<0.001).The 25(OH)D level in KL grade I,II,III and IV was 43.40,30.59,31.56 and 33.93 ng/mL respectively(no difference,P=0.47).Similarly,the KOOS score in sufficient,insufficient and deficient groups were 65.31,60.36 and 65.31,respectively(no difference,P=0.051).CONCLUSION The serum 25(OH)D level is significantly low in younger KOA patients.However,the clinical and radiological severities have no association with serum vitamin D level.Sujit Kumar Tripathy Amrit Gantaguru Saurav Narayan Nanda Sandeep Velagada Anand Srinivasan Manaswini Mangaraj 2020World Journal of Orthopedics2020,11,10:2

18Wind environment around the setback building models显示文摘The irregular shape of buildings always tenders an enormous challenge to the designers.The wind velocity at the pedestrian level has a specific approach from a comfortable point of view.This investigation highlighted the characteristic of the pedestrian level wind velocity for distinct types of asymmetrical setback buildings.The passed study explored the pedestrian level effect for the axisymmetric models,while this study is based on the models that have symmetry about a single axis.This study investigates the pedestrian level flow fluctuation of setback models with single and double side setbacks at multiple levels.The double-side double setback buildings are efficient to reduce 28%-30%velocity in front of the building and 68%-70%velocity behind the building.Finally it suggests that the double side double setback building is efficient to maintain the velocity at the pedestrian level,roof level,and backside of the building.The setback building can easily control the frequency of fluctuating velocity at downstream flow for both along and across wind conditions.Amlan Kumar Bairagi Sujit Kumar Dalui 2021Building Simulation2021,14,5:2
