AIM： To investigate the prevalence and genotype distribution of Torque teno virus （TTV） in patients with different liver diseases and chronic renal failure treated at a referral hospital in North India. METHODS： Whereas prevalence of TFV was based on amplification of conserved region of ORF2 of TTV genome, the genotyping of TFV was carried out using restriction fragment length polymorphism （RFLP） procedure on the N22 region of ORFI. RESULTS： TTV-DNA was detected in 137 of 513 （26.7%） patients with liver diseases and 38 of 65 （58.5%） patients with chronic renal failure. Trv was also detected in 2/7% of healthy controls. The sequence analysis of the PCR product from 10 randomly selected cases failed to show a significant sequence divergence when compared with that of the TRM1 isolate of TTV genotype 1. The results of genotyping in 55 randomly selected patients showed the presence of genotype 1 （G1） in 53 （96.4%） and genotype 2 （G2） in 2 cases （3.6%）, respectively. Other genotypes were not identified in this patient subgroup, suggesting that G1 is predominant in this area. The results of genotyping by RFLP were also supported by phylogenetic tree analysis, where G1 was found to be the major genotype. CONCLUSION： These results indicate that TTV is moderately present in Indian patients, with G1 to be the major genotype in North India. The pathogenicity and etiological role of TTV in different diseases is still a question mark and warrant further studies.

The influence of different welding processes on the mechanical properties and the corresponding variation in the microstructural features have been investigated for the dissimilar weldments of 18% Ni maraging steel 250 and AISI 4130 steel. The weld joints are realized through two different fusion welding processes, tungsten inert arc welding(TIG) and laser beam welding(LBW), in this study. The dissimilar steel welds were characterized through optical microstructures, microhardness survey across the weldment and evaluation of tensile properties. The fiber laser beam welds have demonstrated superior mechanical properties and reduced heat affected zone as compared to the TIG weldments.

Cu–Co–O nano-catalysts as a burn rate modifier for composite solid propellants

引用

Defence Technology（防务技术） 2016年第4期12卷 297-304页

作者： D. Chaitanya kumar RAO Narendra YADAV Puran Chandra joshi Space Engineering and Rocketry Birla Institute of Technology Mesra Ranchi 835215 India

Nano-catalysts containing copper–cobalt oxides(Cu–Co–O) have been synthesized by the citric acid(CA) complexing method. Copper(II) nitrate and Cobalt(II) nitrate were employed in different molar ratios as the starting reactants to prepare three types of nano-catalysts. Well crystalline nano-catalysts were produced after a period of 3 hours by the calcination of CA–Cu–Co–O precursors at 550 °C. The phase morphologies and crystal composition of synthesized nano-catalysts were examined using Scanning Electron Microscope(SEM), Energy Dispersive Spectroscopy(EDS) and Fourier Transform Infrared Spectroscopy(FTIR) methods. The particle size of nano-catalysts was observed in the range of 90 nm–200 nm. The prepared nano-catalysts were used to formulate propellant samples of various compositions which showed high reactivity toward the combustion of HTPB/AP-based composite solid propellants. The catalytic effects on the decomposition of propellant samples were found to be significant at higher temperatures. The combustion characteristics of composite solid propellants were significantly improved by the incorporation of nano-catalysts. Out of the three catalysts studied in the present work, Cu Co-I was found to be the better catalyst in regard to thermal decomposition and burning nature of composite solid propellants. The improved performance of composite solid propellant can be attributed to the high crystallinity, low agglomeration and lowering the decomposition temperature of oxidizer by the addition of Cu Co-I nano-catalyst.

Multi-temporal forest cover dynamics in Kashmir Himalayan region for assessing deforestation and forest degradation in the context of REDD+ policy

引用

Journal of Mountain Science 2016年第8期13卷 1431-1441页

作者： Akhlaq Amin WANI Pawan kumar joshi Ombir SINGH Sumera SHAFI Faculty of Forestry Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir School of Environmental Sciences Jawaharlal Nehru University Silviculture Division Forest Research Institute (FRI) KVK Pulwama Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir

The role of forests is being actively considered under the agenda of REDD＋（Reducing Emissions from Deforestation and Forest Degradation plus） aimed at reducing emissions related to changes in forest cover and forest quality. Forests in general have undergone negative changes in the past in the form of deforestation and degradation, while in some countries positive changes are reported in the form of conservation, sustainable management of forests and enhancement of carbon stock. The present study in the Kashmir Himalayan forests is an effort to assess historical forest cover changes that took place from 1980 to 2009 and to predict the same for 2030 on the basis of past trend using geospatial modeling approach. Landsat data （Multispectral Scanner （MSS）, Thematic Mapper （TM） and Enhanced Thematic Mapper （ETM＋）） was used for the years 1980, 199o and （2001, 2009） respectively and change detection analysis between the dates was performed. The maps generated were validated through ground truthing. The study area （3375.62 km^2） from 1980-2009 has uffered deforestation and forest degradation of about 126 km^2 and 239.02 km^2 respectively which can be claimed under negative options of REDD＋, while as the area that experienced no change （1514 km^2） can be claimed under conservation. A small area （23.31 km^2） observed as positive change can be claimed under positive options. The projected estimates of forest cover for 2030 showed increased deforestation and forest degradation on the basis of trend analysis using Cellular Automata （CA） Markov modeling. Despite the fact that country as a whole has registered a net positive change in the past few decades, but there are regions like Kashmir region of western Himalaya which have constantly undergoing deforestation as well as degradation in the past few decades.

Influence of deposition rate on the structural, optical and electrical properties of electron beam evaporated SnO_2 thin films for transparent conducting electrode applications

引用

Journal of Semiconductors 2018年第8期39卷 20-26页

作者： Nitin kumar Bhawana joshi K.Asokan Department of Applied Physics Gautam Buddha University Materials Science Division Inter University Accelerator Centre

The role of deposition rate in the structural, optical and electrical properties of SnOthin films deposited by electron beam evaporation method is investigated by varying the deposition powers viz. 50, 75, and 100 *** structural characterization of the films is done by X-ray diffraction(XRD) technique. The surface morphology of the films is studied by scanning electron microscopy(SEM). Rutherford back scattering(RBS) measurements revealed the thickness of the films ranging from 200 nm to 400 and also a change in the concentration of oxygen vacancies which is found to be the maximum in the film deposited at the lowest deposition rate. Optical absorption spectrum is recorded using the UV–V is spectroscopy and the films are found to be transparent in nature. A shift in the absorption edge is observed and is attributed to a different level of allowed energy states in conduction band minimum. The Hall effect and electrical measurements show a variation in the carrier concentrations, mobility and resistivity of the films. In order to explore a better compromise in electrical and optical properties for transparent electrode applications, skin depths calculations are also done to find the optimized values of carrier concentration and mobility.

Landscape Characterization of Sariska National Park (India) and Its Surroundings

引用

Geo-Spatial Information Science 2011年第4期14卷 303-310页

作者： joshi Pawan kumar NARULA Sheena RAWAT Asha GHOSH Aniruddha Department of Natural Resources TERI University

Landscape characterization gives an overall information on the status of Land Use and Land Cover （LULC）, changes in its composition and the impact of natural and human influences operating at different spatial and temporal scales. This information can be used to monitor changes in natural forest resources and protected areas, delineate potential conservation areas and can serve in effective management of ecologically fragile landscapes. In the present study, geo-spatial tools were used to characterize the landscape of Sariska National Park and its surroundings. Satellite data was used to prepare LULC maps for 1989 and 2000, change detection analysis and computation of landscape metrics. Climatic data, field records and modeling tools were used to map the potential spread of two invasive species, Prosopis juliflora and Adhatoda vasica. The results show that the forest area increased from 1989 to 2000, indicating better management practices. Landscape metrics （PAFRAC, PLADJ and AI） also support this argument. Improvements in the degraded forest can further enhance this effect. The entire reserve however is suitable for the invasion of P. juliflora and A. vasiea but is more pronounced in Boswellia serrata and Anogeissus pendula - Acacia catechu （open） forests. A detailed landscape characterization map can help forest managers to make important policy decisions concerning issues such as invasive species.

Impacts of Bioinoculants Pseudomonas jesenii MP1 and Rhodococcus qingshengii S10107 on Chickpea (Cicer arietinum L.) Yield and Soil Nitrogen Status

引用

Pedosphere 2019年第3期29卷 388-399页

作者： Divya joshi Ramesh CHANDRA Deep Chandra SUYAL Saurabh kumar Reeta GOEL Department of Microbiology College of Basic Sciences and Humanities Govind Ballabh Pant University of Agriculture and Technology Pantnag ar-263145 Uttarakhand (India) Department of Soil Science College of Agriculture Govind Ballabh Pant University of Agriculture and Technology Pantnagar- 263145 Uttarakhand (India)

Cold-adapted bioinoculants are considered as harbingers of sustainable hill agriculture. Therefore, two previously characterized psychrotolerant diazotrophs, Pseudomonas jesenii MP1 and Rhodococcus qingshengii S10107, were evaluated for their plant growthpromoting potential for chickpea (Cicer arietinum L.) grown under natural field conditions. Comparative analysis of agronomical and biochemical crop parameters revealed the irrelevance of chemical fertilizers for chickpea production;the diazotrophs alone were sufficient to fulfil the crop's nutritional requirement. However, the integrated use of bacterial strains in combination with urea at 20 kg N ha^-1 as urea was being recommended for higher crop yield and better soil nitrogen status. Quantitative polymerase chain reaction (qPCR) and denaturing gradient gel electrophoresis (DGGE)-based soil bacterial dynamics unveiled the persistence of both diazotrophs until the end of the crop maturation period without affecting the native micro-flora. Therefore, these bioinoculants can be explored as natural nitrogen resource, and an additional incentive in their bio-formulation will be a step towards agricultural sustainability.
