International Journal of Automation and computing 2016年第5期13卷 417-427页

作者： S.Renuga devi P.Arulmozhivarman C.Venkatesh Pranay Agarwal School of Electronics Engineering VIT UniversityVellore 632 014Tamil NaduIndia Faculty of Engineering EBET Group of InstitutionsKangayamTamil NaduIndia

With an aim to predict rainfall one-day in advance, this paper adopted different neural network models such as feed forward back propagation neural network （BPN）, cascade-forward back propagation neural network （CBPN）, distributed time delay neural network （DTDNN） and nonlinear autoregressive exogenous network （NARX）, and compared their forecasting capabilities. The study deals with two data sets, one containing daily rainfall, temperature and humidity data of Nilgiris and the other containing only daily rainfall data from 14 rain gauge stations located in and around Coonoor （a taluk of Nilgiris）. Based on the performance analysis, NARX network outperformed all the other networks. Though there is no major difference in the performances of BPN, CBPN and DTDNN, yet BPN performed considerably well confirming its prediction capabilities. Levenberg Marquardt proved to be the most effective weight updating technique when compared to different gradient descent approaches. Sensitivity analysis was instrumental in identifying the key predictors.

Journal of Forestry Research 2009年第A2期20卷 151-155,I0003页

作者： L. Supriya devi, P.S Yadava Department of Life Sciences Manipur University Imphal - 795003 Manipur India

The aboveground biomass dynamics and net primary productivity were investigated to assess the productive potential of Diptero- carpus forest in Manipur, Northeast India. Two forest stands （stand Ⅰ and Ⅱ） were earmarked randomly in the study site for the evaluation of biomass in the different girth classes of tree species by harvest method. The total biomass was 22.50 ***^-1 and 18.27 ***^-1 in forest stand I and II respectively. Annual aboveground net primary production varied from 8.86 to 10.43 ***^-1 respectively in two forest stands （stand Ⅰ and Ⅱ）. In the present study, the values of production efficiency and the biomass accumulation ratio indicate that the forest is at succession stage with high productive potential.

Two-Generation of Sphalerite from Pb-Zn Mineralization of Riasi Inlier, Jammu and kashmir, India: Evidences from Sulphur Isotopes

引用

International Journal of Geosciences 2015年第5期6卷 497-503页

作者： Pankaj k. Srivastava Ishya devi Department of Geology University of Jammu Jammu India

Precambrian carbonate sequence of Riasi Inlier hosts epigenetic lead-zinc mineralization in the form of pockets, lenses and veins. The mineralization is having variable Pb:Zn ratio and shows lithological preferences. The sphalerite rich pockets are concentrated within the dolostone of older Trikuta Formation while galena rich mineralization occurs in form of veins, lenses and pockets hosted within siliceous varieties of dolostone and quartzite belonging to younger khairikot Formation. Sulphur isotope geochemistry is reported in the present paper for the sphalerire and galena from the area for first time. Overall?δ34S of sulphides varies from (+9.67‰ to +34.42‰). Sphalerite ores hosted within older Trikuta Formation and younger khairikot Formation, however, show different?δ34S values. It ranged from +9.67‰ to +10.59‰ for the sphalarite hosted in Trikuta Formation and from +18.38‰ to +34.42‰ for sphalerite hosted within khairikot Formation. Sulphur isotopic data and ore petrographic data suggest that there is two-generation of sphalerite present in the area.

Fermentative production of dextran using Leuconostoc spp. isolated from fermented food products

引用

Frontiers in Biology 2014年第3期9卷 244-253页

作者： C. SUBATHRA devi Shantan REDDY V. MOHANASRINIVASAN School of Biosciences and Techndogy VIT University Vellore-632014 Tamil Nadu India

Leuconostoc spp. （LSland LI1） isolated from sauerkraut and idli batter was selected for dextran production. To enhance the yield of dextran, effects of various parameters such as sucrose concentration, pH, temperature, incubation and inoculum percentage were analyzed. The optimum sucrose concentration for the Leuconostoc spp. （LS1 and LI1） was found to be 15% and 25% respectively. Isolates produced maximum dextran after 20 h of incubation at 29℃ and the optimum pH was found between 8 and 8.5. The inoculum concentration of 7.5% was more favorable for the production of dextran by Leuconostoc spp. （LS1 and LI1）. The growth kinetic parameters were studied and compared for the strains LS1 and LI1. Mass production of dextran was carried out using a stirred tank batch reactor. FTIR analysis was done to determine the functional groups of dextran, sephadex is prepared by cross linking dextran using epichlorohydrin and the functional groups are determined by FTIR analysis.

Recently,a single letter change has taken the world by storm.A group of experts have developed a consensus to upgrade the term non-alcoholic fatty liver disease(NAFLD)to metabolic associated fatty liver disease(MAFLD),suggesting that MAFLD would more accurately reflect not only the disease pathogenesis but would also help in patient stratification for management with ***,the difference of opinion exists,which has made the NAFLD vs MAFLD debate the current talk of the *** review will focus on the plausibility and implications of redefining NAFLD as MAFLD.
