Research ArticleOpen accessIn the abstractSomatic Chromosomes of the Bornean Sambar Deer and Rusa Deer Interspecific HybridsIsmail Idris, Saidi MoinProblem statement: Hybridization has potential benefits to the Malaysian farmed deer industries in terms of increased growth rate and increased proportion of muscle and an improved alignment of feed supply and annual energy requirement. Species or subspecies of different chromosome constitution could mate to produce healthy hybrid offspring in a normal ratio of males and females. If any of the … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 8,692 accessesView PDFCite
Research ArticleOpen accessIn the abstractCementation Analysis by Eddy Current MethodM. Zergoug, H. Oubouchou, N. AmimeurIncrease the hardness, the endurance and the life time of material can be realised by surface treatments and remetallings, the electromagnetic properties of steels depend on their composition, their microstructures and constraints applied. We can use the electric and magnetic parameters to evaluate their microstructure. The object of this work is the characterization of cementation by the non-destructive methods and … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,569 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiological Control of Rice Blast (Magnaporthe oryzae) by use of Streptomyces sindeneusis isolate 263 in GreenhouseM. Ebrahimi Zarandi, G.H. Shahidi Bonjar, F. Padasht Dehkaei et al.Soil Actinomycetes particularly Streptomyces spp. have antagonistic activity against wide range of plant pathogens. In the recent decades they have attracted high interests as biocontrol agents. In search for finding such principles, in vitro suppression of Magnaporthe oryzae the causal agent of rice blast disease was studied by use of Streptomyces sindeneusis isolate 263 in greenhouse. Spray of rice seedling-leaves … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 11,496 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review on Supercritical Fluid Extraction as New Analytical MethodK. A. Abbas, A. Mohamed, A. S. Abdulamir, H. A. AbasThis review study summarized the Supercritical Fluid Extraction (SFE) as new analytical method. The advantage and disadvantage of CO2 (SC-CO2 )as well as special applications of SFE in food processing such as removal of fat from food, enrichment of vitamin E from natural sources, removal of alcohol from wine and beer, encapsulation of liquids for engineering solid products and extraction … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 10,505 accessesView PDFCite
Research ArticleOpen accessIn the abstractSmall Size and Dual Band of a Quadratic Koch Dipole Fractal Antenna DesignFawwaz J. Jibrael, Faez F. Shareef, Wafaa S. MummoThe performance and analysis of a small size, low profile and dual band quadratic Koch curve dipole antenna was introduced. The proposed antenna design, analysis and characterization had been performed using the method of moments (MoM) technique. The radiation characteristics, VSWR, reflection coefficient and input impedance of the proposed antenna were described and simulated using 4NEC2 software package, MATLAB v7.2 … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,120 accessesView PDFCite
Research ArticleOpen accessIn the abstractTaxonomic Significance of ISTR to Discriminate Species in AgavaceaeMartha Isabel Torres-Morán, Norma Almaraz-Abarca, Ana Paulina Velasco-Ramírez et al.Family Agavaceae is endemic of American Continent. From the around 300 species recognized in this family, 217 occur in Mexico. Relevant ethnobotanic relationships among Agavaceae and the several native human cultures of the American Continent have been established since prehispanic times. Agave is one of the most important genus in that family due to its great diversity and abundance, mainly … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 8,195 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneralization of Differential OperatorMaslina Darus, Rabha W. IbrahimThe main objective of this study was to generalize a differential operator. The generalized differential operator reduced to many known operators studied by various authors. New classes containing this generalized operator were studied and characterization of these classes was obtained. Further, subordination and superordination results involving this operator were studied and obtained the sandwich theorem. …Journal of Mathematics and Statistics, Vol. 4, Issue 3 · 30 Sep 2008 · 6,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractTamoxifen Drug Loading Solid Lipid Nanoparticles Prepared by Hot High Pressure Homogenization TechniquesNagi A.

So, Solid Lipid Nanoparticles have recently received considerable attention as alternative drug delivery carrier. In this study Solid Lipid Nanoparticles (SLNs) containing tamoxifen, nonsteroidal antiestrogens have been loaded and to be … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 3 · 30 Sep 2008 · 15,176 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrobial Biodiversity Screening for Metal Accumulators from Mineral Ore Rich Site in Andhra Pradesh, IndiaAditya Kumar Sarkar, Susmita Roy, Ananya Pal et al.Problem statement: Since the site selected for screening was a source of magnetite, the objective of this study was to isolate some groups of magnetotactic bacteria and microbes with potential of metal accumulation. Approach: The culture based approach was used for the study. Pure isolates obtained were characterized on the basis of morphology, biochemical tests, physiology as well as at … …OnLine Journal of Biological Sciences, Vol. 8, Issue 2 · 30 Jun 2008 · 7,553 accessesView PDFCite
Research ArticleOpen accessIn the abstractWeyl's Type Theorems for Quasi-Class A OperatorsM.H.M. Rashid, M.S.M. Noorani, A.S. SaariA variant of Weyl theorem for a class of quasi-class A acting on an infinite complex Hilbert space were discussed. If the adjoint of T is a quasi-class A operator, then the generalized a-Weyl holds for f(T) , for every function that analytic on the spectrum of T. The generalized Weyl theorem holds for a quasi-class A was proved. Also, … …Journal of Mathematics and Statistics, Vol. 4, Issue 2 · 30 Jun 2008 · 7,224 accessesView PDFCite
