Research ArticleOpen accessIn the keywordsComparative Study by Electrochemical Impedance Spectroscopy (EIS) On The Corrosion Resistance of Industrial and Laboratory Zinc CoatingsY. Hamlaoui, F. Pedraza, L. TifoutiIn this work, corrosion monitoring of Zn-based coatings is investigated through potentiodynamic and electrochemical impedance spectroscopy (EIS) methods. The first part of the study is devoted to galvanised coatings conventionally manufactured in the industry. The second part focuses on the corrosion resistance of a laboratory-made electrolytic coating. For such purpose, the corrosion behaviour is studied in NaCl media under various … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,594 accessesView PDFCite

Research ArticleOpen accessIn the keywordsINCREASED NUTRIENT SOLUTION CONCENTRATION DURING EARLY FRUIT DEVELOPMENT STAGES ENHANCES PUNGENCY AND PHENYLALANINE AMMONIA-LYASE ACTIVITY IN HOT CHILI (CAPSICUM ANNUUM L.)Parichat Dittakit, Thammasak ThongketThe effect of increased nutrient concentration during different fruit development stages on the yield, pun-gency and PAL enzyme activity in hot chili cv. ’Super hot’ was studied during August 2009-January 2010. The seedlings were planted in plastic containers containing 20 L of coconut-coir-dust substrate placed inside a plastic-roofed net house and received Resh’s Tropical Dry Summer nutrient solution at a … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 27 Dec 2013 · 7,492 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInhibition of Skin Colour Darkening (Skin Clearing and Lightening); Skin Firming; Body Calming and Body Vitalizing Effects of Vernonia amygdalina Leaf ExtractUtoh-Nedosa Uchechukwu AnastasiaProblem statement: Obese human subjects treated with oral Vernonia amygdalina (V. amygdalina) aqueous leaf extract for one month who experienced the anti-obesity effects of V. amygdalina leaf extract reported a lighter; clearer; more glowing and firmer skin as side effects of the treatment (unpublished findings). In this study, oral Vernonia amygdalina aqueous leaf extract was taken daily for six months … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 2 · 17 Aug 2011 · 8,259 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of MgCl2 on Germination, Growth and Biomass Allocation of the Radish CV. "Cherry Belle"William Brandenburg, Catherine KleierProblem statement: To determine the effect of MgCl2 on radish (Raphanus sativus), plants were grown in controlled environmental growth chambers and given one of three watering treatments; 0.01, 0.1 and 0 M (control) MgCl2. Approach: At high concentrations (0.1 M), MgCl2 was toxic resulting in very low (44%) germination rates and the subsequent death of all but three undersized plants … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 8,232 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Software Agent for Speech Abiding SystemsR. Manoharan, K. Vivekanandan, V. SundaramProblem statement: In order to bring speech into the mainstream of business process an efficient digital signal processor is necessary. The Fast Fourier Transform (FFT) and the butter fly structure symmetry will enable the harwaring easier. With the DSP and software proposed, togetherly established by means of a system, named here as “Speech Abiding System (SAS)”, a software agent, which … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 7,744 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOptimization of Cultural Conditions for Production of Exopolysaccaride by Halomonas marina HMA 103 under Batch-CultureArundhati Pal, Amrita Biswas, Sriya Chatterjee, A. K. PaulA moderately halophilic bacterium, Halomonas marina HMA 103 (MTCC 8968) accumulating intracellular polyesters also produced significant amount of exopolysaccharides (EPS) under batch-culture. Production of EPS by the bacterium was more or less parallel with the growth in modified basal synthetic medium. During growth, it produced 0.46 g/L of EPS after 50 h of incubation and was accompanied by the complete … …Current Research in Microbiology, Vol. 6, Issue 2 · 27 Jul 2015 · 7,932 accessesView PDFCite

Research ArticleOpen accessIn the keywordsKinetic Study of the Effect of Selected Surfactants on Corrosion of CopperHowaida M. El-KashlanThe rates of copper corrosion were determined by measuring the limiting current of anodic dissolution of copper in phosphoric acid in presence and in absence of cetyl trimethyl ammonium bromide (CTAB) and cetyl pyridinium bromide (CPYB). The rate of corrosion is found to decrease by increasing the concentration of the surfactant. The percentage of inhibition ranged from 1.85 to 33.97% … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,137 accessesView PDFCite
