Approach: Gurpi formation consisted of thin to medium sized layers of gray marl and marlstone interbedded with thin layers of argillaceous limestone and shale. The dominant microfacies in this … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,738 accessesView PDFCite
Research ArticleOpen accessIn the abstractSuitability Evaluation of Groundwater for Irrigation, Drinking and Industrial PurposesM. A. Hakim, A. S. Juraimi, M. Begum et al.Problem statement: Groundwater is an important source of freshwater for agricultural, drinking and domestic uses in many regions of the world including Bangladesh. Demand of groundwater has been increasing day by day for irrigation by bringing more area under cultivation. As a drinking water the bottled water market currently has an average annual growth rate of 7.4% between 2002 and … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 8,646 accessesView PDFCite
Research ArticleOpen accessIn the abstractPresence and Origin of Fluoride in the Complex Terminal Water of Ouargla Basin (Northern Sahara of Algeria)Imed Eddine Nezli, Samia Achour, Mohamed Djidel, Saïd AttalahProblem statement: The underground waters in the oriental regions of the Algerian Sahara, present real chemical quality problems. Their content in fluorides always exceeds the limit of the recommended levels. That is 0.8 mg L-1, according to the maximum temperature in the region. Combined to a high salinity, it affects the health of the population living around the region. The … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,677 accessesView PDFCite
Research ArticleOpen accessIn the abstractContribution to the Study of the Origin of Salinity in Alluvial Aquifer System in the Ain chabro-Hammamet (North-East ALGERIA)K. Seghir, N. KhériciTebessa is located in the Algerian North East. It is characterized by a semi-arid continental climate with an average interannual precipitation of less than 400 mm. It belongs to the Eastern Saharian Atlas field along the Tunisian borders. It is drained by a certain number of the wouady of which Chabro and Bouakous are the most important. The surface area … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,611 accessesView PDFCite
Research ArticleOpen accessIn the abstractProteomics Approach for Investigating the Disease Resistance Using Cucumber as Model PlantSaligrama A. Deepak, Junko Shibato, Hideo Ishii et al.The profile of proteins induced in cucumber leaves pretreated with Acibenzolar-S-Methyl (ASM) and challenge inoculated with Colletotrichum orbiculare are presented. ASM was applied to the first leaf and the third leaf collected at different time intervals of 0-48 h and the total protein extracted using trichloroacetic acid acetone was analyzed by two-dimensional gel electrophoresis. Increased expressions of pyridoxine biosynthesis protein, … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 7,243 accessesView PDFCite
Research ArticleOpen accessIn the abstractSesame Oil As A Protective Agent Against Doxorubicin Induced Cardio Toxicity In RatKaneez F. Shad, Suhail Al-Salam, Alaaeldin A. HamzaThe therapeutic value of doxorubicin (DXO) as anticancer antibiotic is limited by its cardiotoxicity. This study aimed to investigate the protective effect of sesame oil against DXO-induced cardiotoxicity and oxidative stress. The administration of DXO (20 mg/kg) to Wister male rats, increased serum aspartate aminotransferase and creatine kinase activities (as cardiotoxicity indices) as well as cardiac malondialdehyde and protein carbonyl … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 4 · 31 Dec 2007 · 7,672 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of D- and L-Glucose and Mannitol on Retinal Capillary Cells: Inhibition by Nanomolar AminoguanidineYongxin Yu, Wei Li, Barbara Wojciechowski et al.Hyperglycemia may contribute directly to pericyte loss and capillary leakage in early diabetic retinopathy. To elucidate relative contributions of glycation, glycoxidation, sugar autoxidation, osmotic stress and metabolic effects in glucose-mediated capillary damage, we tested the effects of D-glucose, L-glucose, mannitol and the potentially protective effects of aminoguanidine on cultured bovine retinal capillary pericytes and endothelial cells. Media (containing 5 mM … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 4 · 31 Dec 2007 · 7,751 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Low-Temperature Technology of Producing Calcium Feed Phosphate with MicroelementsJózef HoffmannThe possibility of producing feed calcium phosphates in a way ensuring a low physical water content in the product was investigated in laboratory conditions. For this purpose the process use of a phosphoric acid solution with a higher (than in conventional methods) P2O5 content (53-63% by wt. P2O5) with CaO (molar fraction of 0.5-0.8) and CaCO3 in the phosphoric acid … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,743 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Provenance of the Varzaneh Aeolian Sand Field Regarding to Lithology and Texture, SW Esfahan, IranH. Pakzad, R. AjalloeianThe main mineralogical/lithological composition of the Varzaneh aeolian sands is sedimentary and igneous lithics.
