Research ArticleOpen accessAll words, across the recordEffect of Some Fermentation Parameters on Ethanol Production from Beet Molasses by Saccharomyces cerevisiae CAIM13Awatif Abid Al-JudaibiProblem Statement: Some component of fermentation medium showed to reduce the Saccharomyces cerivisae production of ethanol. Approach: This study was designed to evaluate the role of some fermentation parameters in affecting ethanol productivity from beet molasses BM by Saccharomyces cerevisiae CAIM13. Results: Increase in cell concentration (inoculums size) of the yeast above 3.6×105 cells/100 mL decreased the ethanol yield. The … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 25 Jun 2011 · 8,921 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordComparative Study of the Effect of Lossy and Lossless Block Based Binary Plane Techniques on Medical ImagesNalla Subhash Chandra, Mahaboob Basha Shaik, A. Govardhan, M. BalrajuProblem statement: The general and medical images in specific contain different regions holding information of different significances. To elaborate medical information, the doctor prefers to focus on certain selected region (s) of interest. So for medical images the diagnostically important regions must be preserved at high quality, whereas the rest of the image is required only in a contextual sense. … …Journal of Computer Science, Vol. 6, Issue 11 · 23 Oct 2010 · 7,380 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect of Partial Orientation in [100] Direction on the Magnetic Properties of Co-Ferrite Prepared from Nano ParticlesH. M. El-SayedChemical co-precipitation method was used for the preparation of Co-ferrite nano particles. The particle size was about 18 nm. A magnetic anisotropy of Co-ferrite could be increased by applying an external magnetic field during the pressing of the nano particles before the final sintering. This anisotropy enhanced the squareness and the coercivity of investigated samples. …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,220 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect of Infrastructure Development on Income Generation: A Study on Jamuna Bridge Project in BangladeshShaikh MoniruzzamanThis research is an attempt to examine the impact of infrastructure development on income generation in the north eastern region of Bangladesh which enjoyed a wide range of amenities after the construction of Jamuna Bridge in 1998. The application of 'difference in difference estimator' using the pooled household level income data of the treatment and control area in the pre … …Journal of Social Sciences, Vol. 4, Issue 2 · 30 Jun 2008 · 8,365 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect of Processing on the Electrical Properties of Spray-Deposited SnO2:F Thin FilmsShadia J. Ikhmayies, Riyad N. Ahmad-BitarHighly transparent SnO2:F thin films were produced by the Spray Pyrolysis (SP) technique to be used as forcontacts in the home made CdS/CdTe solar cells. Films of thickness 100-200 nm were prepared at substrate temperatures in the range 380-480°C. To improve the electrical properties of the films, annealing in nitrogen atmosphere at 400°C and etching by HNO3 were tried. The … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,002 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordExperimental Study of Parameters Influencing the Purity of Potassium Sulfate Fertilizer Produced from Jordanian Raw MaterialsMousa GougazehThe general objective of the present investigation was to make a contribution towards improving the purity of the produced potassium sulfate from (KCl, Arab Potash Company-Dead Sea) and (H2SO4, Jordanian Phosphate Company). The process parameters influencing the contamination of the poisoning chlorine within the product were experimentally investigated. The experiments were performed in a small-scale batch reactor equipped with a … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 7,042 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect of Gamma Irradiation on the Structure Diffusion Coefficient of Co-Zn Doped FerriteDalal Mohammed HemedaA series of the ferrite system Co0.6Zn0.4MnxFe2-xO4 with (x = 0.7, 0.8, 0.9 and 1) were prepared by general ceramic method. The X-ray diffraction patterns confirmed the formation of the cubic single phase structure. The lattice parameter and the crystal size increased after irradiation which was attributed to the formation of ferrous ions of larger radius than that of ferrous … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,728 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAn Approach to Develop a Dynamic Job Shop Scheduling by Fuzzy Rule Based System and Comparative Study with the Traditional Priority RulesRamin Ahmed, Md. Muzahid Khan, Md. Hasibul Haque, Md. Hasibur RahmanThis paper aims at developing a dynamic job shop scheduling by establishing fuzzy rule based system and comparing its effectiveness with the traditional priority rules. In order to understand the priorities of different jobs in a job shop, the paper investigates all the contributing criteria of different parameters. Since the traditional priority rules only emphasis on a single parameter at … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 11 Feb 2016 · 8,365 accessesView PDFCite
