Research ArticleOpen accessIn the abstractConformational Analysis of Trans-3, 6-Dibutanal-1, 2, 4, 5-TetroxaneEduardo A. Castro, Mariela I. Profeta, Jorge M. Romero et al.We report the results of theoretical semiempirical AM1 and PM3 molecular orbital methods on the conformational analysis of the title compound. The relative stability of different isomers and conformers are discussed on the basis of well defined electronic and steric effects, which are rather helpful in order to understand the relative stabilities. …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,695 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiological Control of Fusarium oxysporum f. sp. melonis, the Causal Agent of Root Rot Disease of Greenhouse Cucurbits in Kerman Province of IranSara Shafii Bafti, Gholam H.S. Bonjar, Sonia Aghighi et al.Antagonistic activity of 178 soil actinomycete isolates was assayed against Fusarium oxysporum f. sp. melonis Schlecht, Emend (Snyde and Hansen) cause of root rot and fusarium wilt of greenhouse cucurbits in Kerman Province, southeast of Iran. From tested isolates, Streptomyces olivaceus (strain 115) showed anti-fusarium activity revealed through screening and bioassays by agar disk and well-diffusion methods. The active strain … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,993 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Transcript Labeling Techniques and Development of a Membrane-based Parallel Gene Expression AssayMark A. Fisher, Bonnie B. Plikaytis, Thomas M. ShinnickAn inexpensive alternative to micro arrays was developed to examine the expression of small sets of genes in parallel and used to compare direct and indirect transcript labeling methods. Psoralen-biotin direct labeling was ~10-fold less sensitive than reverse transcriptase-biotin-dUTP labeling, but the enzymatic method generated higher levels of background noise in miniarray hybridizations. The reproducibility of hybridization intensities was the … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,868 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential of Rice Husk and Rice Husk Ash for Phenol Removal in Aqueous SystemsA. H. Mahvi, A. Maleki, A. EslamiThe potential of rice husk and rice husk ash for phenol adsorption from aqueous solution was studied. Batch kinetics and isotherm studies were carried out under varying experimental conditions of contact time, phenol concentration, adsorbent dose and pH. Adsorption equilibrium of rice husk and rice husk ash was reached within 6 hours for phenolic concentration 150-500 μg/L and 3 hours … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 10,171 accessesView PDFCite
Research ArticleOpen accessIn the abstractDepth Estimation of 2-D Magnetic Anomalous Sources by Using Euler Deconvolution MethodM. G.E. Dawi, Liu Tianyou, Shi Hui, Luo DapengEuler deconvolution method is the method of depth estimation which is best suited for anomalies caused by isolating and multiple anomalous sources. In the present study, algorithmic programs based on generalizing linear inverse theory, uses a least square sense to solve for Euler’s equation is being written. The Euler technique that can estimate the location of a simple body from … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,459 accessesView PDFCite
