Research ArticleOpen accessIn the abstractAn Electrochemical Investigation of the Redox Properties of Murexide in Aqueous and Non-Aqueous MediaHossnia S. MohranKnowledge of solvent effects on the redox properties of Murexide (Mu) is important for understanding its role as an electron acceptor in analytical and inorganic chemistry. In the present study, an investigation of the electrochemical behavior of the compound by both Cyclic Voltammetry (CV) and Electrochemical Impedance Spectroscopy (EIS) in both aqueous and non-aqueous solutions was undertaken. It is suggested … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,738 accessesView PDFCite
Research ArticleOpen accessIn the abstractTrace Metals Co-Toxicity in Hard Body Structures of Liza klunzingeri (Mugilidae: Perciformes) Mullet FishA.H. Bu-Olayan, B.V. Thomas, S.M.H. Al-HusainiThe possibility of inorganic pollutants causing stress to the marine ecosystem instigated us to conduct eco-toxicological tests on the predominant trace metals (Cu, Zn, Pb and V) in commercial important fish. Among the four metals, V had the lowest observed effect concentration (LOEC: LC15) at 6.3 µg L-1. Toxicity tests (96 h) using Multi factor Probit analysis revealed V (6.3 … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,514 accessesView PDFCite
Research ArticleOpen accessIn the abstractNutritional control of HIV-AIDS-A case for SeleniumParisa Kalantari, Hema Vunta, Umamaheswari D. Palempalli et al.Selenium (Se) is a micronutrient that is incorporated into proteins. Some of the selenoenzymes such as GPXs and thioredoxin reductases exhibit glutathione peroxidase-dependent activities towards organic and inorganic peroxides. Thus, selenoenzymes play a pivotal role in mitigating oxidative stress caused by accumulation of peroxides. In this respect, selenoproteins may interfere with the transcription-driven by oxidative stress-dependent signaling mechanisms to influence … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 7,344 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Dietary Yeasts Enriched with Cu, Fe and Mn on Digestibility of Main Nutrients and Absorption of Minerals by Growing PigsDaniel Korniewicz, Zbigniew Dobrzanski, Katarzyna Chojnacka et al.Yeasts Saccharomyces cerevisiae containing in 1 kg of dry product, separately 32.0 g Fe (Y-Fe), 23.0 g Cu (Y-Cu), 35.4 g Mn (Y-Mn), were used as the source of these microelements in complete diet for growing pigs. If considering livestock requirements, feed supplementation with this organic form of microelements, covered animals’ requirements in: Fe-27%, Cu-75%, Mn-30%. ZnO was the source … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,707 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential Air and Groundwater Pollution from Continuous High Land Application of Cheese WheyA.E. Ghaly, D.G. Rushton, N.S. MahmoudExperiments were performed, using eighteen 280 cm deep soil columns with 20 cm inside diameter, to determine the relative amounts of nitrogenous compounds leached and volatilized from soils receiving high application rates of cheese whey during two seasons. Three soils (loamy sand, sandy loam and sandy clay loam) and two cheese whey application rates (560 and 840 kg-N ha-1), that … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 7,277 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Nitrogen and Potassium Uptake and Efficiency of Two Rice Varieties Cultivated on an Acid SoilShajarutulwardah Mohd Yusob, Osumanu Haruna Ahmed, Wan Asrina Wan Yahaya, Nik Muhamad Ab. MajidA pot study was carried with the following objectives: (i) To investigate N and K uptake of MR 220 and ARC 2 rice varieties grown on Bekenu series (Tipik Tualemkuts), and (ii) To investigate N and K use efficiency of MR 220 and ARC 2 grown on Bekenu series. Treatments evaluated were: (i) MR 220 and ARC 2 under fertilized … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 7,846 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential Environmental and Health Impacts of High Land Application of Cheese WheyA. E. Ghaly, N.S. Mahmoud, D.G. Rushton, F. ArabA laboratory scale experiment was carried out to study the transformation and transport of nitrogenous compounds in soils receiving high application rates of cheese whey (twice the nitrogen requirement for crops). The experimental apparatus consists of 36 soil columns constructed of 20 cm inside diameter PVC pipes. Three types of soil (sandy loam, loam and sandy clay loam) and three … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 8,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Total Dissolved Solids on Aquatic Organisms: A Review of Literature and Recommendation for Salmonid SpeciesPhyllis K. Weber-Scannell, Lawrence K. DuffyTotal dissolves solids (TDS) are naturally present in water or are the result of mining or some industrial treatment of water. TDS contain minerals and organic molecules that provide benefits such as nutrients or contaminants such as toxic metals and organic pollutants. Current regulations require the periodic monitoring of TDS, which is a measurement of inorganic salts, organic matter and … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Jan 2007 · 23,405 accessesView PDFCite
