Approach: The profiles from follicular phase (6-12 days); ovulatory phase (13-14 days) and luteal phase (15-26 days) of menstrual cycle samples were compared … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 3 · 30 Sep 2010 · 8,365 accessesView PDFCite
Research ArticleOpen accessIn the abstractLippia graveolens and Carya illinoensis Organic Extracts and there in vitro Effect Against Rhizoctonia Solani KuhnFrancisco Daniel Hernandez-Castillo, Francisco Castillo-Reyes, Gabriel Gallegos-Morales et al.Problem statement: Plant extracts with polyphenolic compounds obtained with different solvents have been evaluated against plant pathogens. However, most of these extract have been obtained using solvents no allowed under an organic production context. Approach: In the present research was to evaluate the inhibitory effect of polyphenolic extracts from L. graveolens and C. illinoensis, obtained with alternative organic solvents (lanolin … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,991 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnzymatic Synthesis of Palm Alkyl Ester Using Dialkyl Carbonate as an Alkyl DonorsRoila Awang, Choo Yuen MayProblem statement: Though efficient in terms of reaction yield and time, the chemical approach to synthesizing alkyl ester has drawback such as difficulties in the recovery of glycerol and the need for removal of salt residue. On the other hand, biocatalyst allow for synthesis of specific alkyl esters and easy recovery of glycerol. However, the solvent-free alcoholysis, does not give … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,235 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Silver/Polyvinilpirrolidone (Ag/PVP) Nanoparticles Using Gamma Irradiation TechniquesShawkat Salameh Gasaymeh, Shahidan Radiman, Lee Yook Heng et al.Problem statement: In this study, attempts had been made to synthesize silver (Ag)/Poly Vinylpyrolidone (PVP) nanoparticles by ionizing radiation and at the same time overcoming some of the disadvantages previously reported by other methods such as impurities, solvent toxicity, size and distribution control and difficulty in their preparation that limits their commercialization potential. Approach: The use of this alternative method … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 9,962 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Implications of a Health Promotion Program on the Knowledge and Practice of Automotive Workers Exposed To SolventRumaizah Ruslan, Zailina Hashim, Ismi Arif Ismail et al.Problem statement: An in-house health promotion program aimed at promoting safety and health awareness when handling organic solvents at the workplace was carried out and its effectiveness was evaluated by comparing the Knowledge, Attitude and Practices (KAP) scores at the pre and post-intervention phase. Approach: A total of 104 workers participated in the program and another 176 workers served as … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 8,027 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpiral Wound Reverse Osmosis Membranes for the Recovery of Phenol Compounds-Experimental and Parameter Estimation StudiesG. Srinivasan, S. Sundaramoorthy, D.V.R. MurthyProblem statement: Reverse osmosis is increasingly used as a separation technique in chemical and environmental engineering for the removal of organics and organic pollutants present in waste water. The removal of an organic compound, namely phenol, using a polyamide membrane was investigated in this study. Waste water containing phenol present a serious environmental problem and increasing attention is being given … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 9,304 accessesView PDFCite
