Research ArticleOpen accessIn the abstractCuInSe2 (CIS) as A light Absorption Layer of Photovoltaic Solar-CellsOmar Abdulsada AliArrested precipitation methode used to synthesize CuInSe2 (CIS) nanocrystals were added to a hot solvent with organic capping ligands to control nanocrystal formation and growth. CIS thin films deposited onto Soda-Lima Glass (SLG) substrate by spray-coat, then selenized in Ar-atmosphere to form CIS thin films. PVs were made with power conversion efficiencies of 0.631% as-deposited and 0.846% after selenization, for … …Current Research in Nanotechnology, Vol. 7, Issue 1 · 29 Feb 2016 · 14,781 accessesView PDFCite
Research ArticleOpen accessIn the abstractFUNCTIONAL PROPERTIES OF PROTEIN CONCENTRATE FROM BLACK COWPEA AND ITS APPLICATIONAnuchita Moongngarm, Sirinapa Sasanam, Watcharee Pinsiri et al.Black cowpea (Vigna unguiculata L. Walp.) is high in protein, which makes it suitable for use as a protein supplement in food products. However, direct application of cowpea flour in food products is limited as it may affect some quality aspects of foods. Protein concentrate and isolate are a form of the protein that is gaining interest in industry. Therefore, … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 29 Nov 2014 · 6,403 accessesView PDFCite
Research ArticleOpen accessIn the abstractCLIMATE CHANGE IMPACT ASSESSMENT ON WATERSHED HYDROLOGY: A COMPARISON OF THREE APPROACHESSomsubhra Chattopadhyay, Manoj K. JhaSeveral methods of impact assessment have been developed over the years which basically incorporate future climate projections of atmospheric-ocean circulation based climate models into the simulation of land surface hydrological processes. This study attempted to evaluate three methods of climate change impact assessment: (a) Frequency perturbation method, (b) direct method and (c) delta change method. A well-calibrated hydrologic model, Soil … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 27 Mar 2014 · 8,597 accessesView PDFCite
Research ArticleOpen accessIn the abstractCritical Aging Segments of Power Transmission LineH. H. Goh, N. E. Chin, Q. S. Chua et al.Nowadays, blackouts or sags of a conductor are threatening the safety and stable run of the power transmission lines. These phenomena happen due to the environmental conditions which change over the time, such as aging or temperature variations, precipitation and hotspots of power transmission lines as a result of extreme weather conditions. A precipitation condition result loses of heat from … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 9 Dec 2013 · 9,264 accessesView PDFCite
Research ArticleOpen accessIn the abstractSeasonal Autoregressive Integrated Moving Average Model for Precipitation Time SeriesYan Wang, Xinghua Chang, Meng Gao, Xiyong HouPredicting the trend of precipitation is a difficult task in meteorology and environmental sciences. Statistical approaches from time series analysis provide an alternative way for precipitation prediction. The ARIMA model incorporating seasonal characteristics, which is referred to as seasonal ARIMA model was presented. The time series data is the monthly precipitation data in Yantai, China and the period is from … …Journal of Mathematics and Statistics, Vol. 8, Issue 4 · 20 Feb 2013 · 12,655 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmerging Trends in Designing Short and Efficient Protein Purification ProtocolsSaurabh Gautam, Joyeeta Mukherjee, Ipsita Roy, Munishwar Nath GuptaProtein purification is carried out in both academic and industrial sectors. Both non-chromatographic approaches (precipitation, crystallization, partitioning) and chromatographic methods are used. When recombinant proteins are over expressed in foreign hosts, inclusion bodies are obtained. Many purification methods can be used to refold proteins. Many strategies allow one to avoid formation of inclusion bodies. The concept of affinity based separation … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 4 · 25 Dec 2012 · 9,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation-Properties Relation of Mn-Cu Hopcalite CatalystArdita Mele, Ilo Mele, Altin MeleProblem statement: The Mn-Cu hopcalite catalyst was used for the conversion of CO to CO2 at low temperatures. It was the catalyst of choice in the gas masks for respiratory protection in mines, aircrafts, military, spatial laboratories. Approach: The efficiency of hopcalite catalyst depends on its surface parameters. Its surface characteristics can be influenced from the chosen way of the … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 7,888 accessesView PDFCite
