In the present study, an effort was made to investigate the effect of physio-chemical parameters on the silver nanoparticle formation with the fungus Chrysosporium tropicum Carmichael and Fusarium oxysporum Schltdl. Approach: The possibilities to manipulating the geometry of silver … …Current Research in Nanotechnology, Vol. 2, Issue 1 · 20 Jan 2012 · 19,454 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Citrullus colocynthis Pulp Extract on the Liver of Diabetic Rats a Light and Scanning Electron Microscopic StudyMohammad Khalil, Gamal Mohamed, Mohammad Dallak et al.Problem statement: The goal of the current investigation was to clarify the effects of Citrullus colocynthis pulp extract on the structure of the liver of diabetic rats at both light and scanning electron microscopic levels. Approach: Forty-eight adult male albino rats were equally allocated into four groups: Group1: control, Group 2: Citrullus colocynthis-treated, Group 3: diabetic rats and Group4: diabetic … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 3 · 30 Sep 2010 · 9,478 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Process Parameters on Electrical Discharge Machined Job Surface IntegrityA.K.M. Asif Iqbal, Ahsan Ali KhanProblem statement: Electrical Discharge Machining (EDM) is the most widely used non conventional machining process for removing material from workpiece by means of a series of repeated electric discharges. Electrical Discharge milling (ED-milling) is an emerging technology where a cylindrical tool electrode follows a programmed path in order to obtain the desired shape of a part. During machining of metals … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,584 accessesView PDFCite
Research ArticleOpen accessIn the abstractOsteoporosis Induction in Animal ModelKamran Kaveh, Rashid Ibrahim, Mohd Zuki AbuBakar, Tengku Azmi IbrahimProblem statement: Osteoporosis; the major health problem is an imperative disease requires a significant attention to discover different aspects of this threatening abnormality. There are some problems in osteoporotic human population to conduct researches such as lack of a homogenous sample size or ethical problems. So, there was a need to have protocol in animal model to let the scientists … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 9,305 accessesView PDFCite
