Research ArticleOpen accessIn the abstractOptical Properties of Crosslinked Chitosan Thin Film with Glutaraldehyde Using Surface Plasmon Resonance TechniqueYap Wing Fen, W. Mahmood Mat Yunus, Mohd Maarof Moksin et al.Problem statement: The aim of this research is to study the optical properties of crosslinked chitosan thin film with glutaraldehyde using Surface Plasmon Resonance (SPR) technique. Approach: The crosslinked chitosan is synthesized by homogeneous reaction of medium molecular weight chitosan in aqueous acetic acid solution with glutaraldehyde as crosslinking agent. Four different amount of chitosan, i.e., 0.40, 0.50, 0.60 and … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 28 Jan 2011 · 9,624 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Cooling and Supplemental Bovine Somatotropin on Milk Production relating to Body Glucose Metabolism and Utilization of Glucose by the Mammary Gland in Crossbred Holstein CattleSiravit Sitprija, Somchai Chanpongsang, Narongsak ChaiyabutrProblem statement: The low milk yield and shorter persistency of lactation of dairy cattle is the major problem for the dairy practices in the tropics. High environmental temperatures and rapid decline of plasma growth hormone level can influence milk production. Regulation of the milk yield of animals is mainly based on the mechanisms governing the quantity of glucose extracted by … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 3 · 30 Sep 2010 · 7,341 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 abstractThe Use of Insects as Human Food in ZambiaA.E. GhalyProblem statement: The life cycle and culture structure of two commonly eaten worms in Zambia (Isoberlinia paniculata and Miombo/Mopani) were evaluated. The worms were grown on an artificial medium to evaluate the potential of producing them on a commercial scale. Approach: An interesting characteristic of the worms studied was that they reached their maximum weight and maximum length at the … …OnLine Journal of Biological Sciences, Vol. 9, Issue 4 · 31 Dec 2009 · 8,701 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Black Cutworm as a Potential Human FoodA.E. GhalyProblem statement: The black cutworms (Agrotis ipsilon) were grown in an artificial medium to evaluate their potential as a human food. Approach: The culture was started from moths and the life cycle and culture structure were evaluated. There was an initial adjustment period of 3 days during which the growth of the larvae was very slow. The size of the … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 4 · 31 Dec 2009 · 7,573 accessesView PDFCite
Research ArticleOpen accessIn the abstractCoating and Encapsulation of Nanoparticles using Supercritical AntisolventG. H. Chong, R. Yunus, N. Abdullah et al.Problem statement: Literature on the production of nanoparticles using supercritical fluids is substantial, but comparatively much less for nanoencapsulation. Approach: In this study, a modified Supercritical Anti Solvent (SAS) apparatus was fabricated for use in the production of nanoparticles using carbon dioxide as the supercritical fluid (SCF). SAS technique involves precipitation of solids from liquid solution under supercritical antisolvent-induced condition. … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 8,417 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Characterization of Novel Metal Accumulating Extracellular Protease Secreting Bacteria from Marine Coastal Region of Digha in West Bengal, IndiaSusmita Roy, Kaushal Mishra, Sanhita Chowdhury et al.Problem statement: The objective of the present piece of work was to explore the existing biodiversity of protease secreting microbes in a marine ecosystem, the site selected being the coastal region of West Bengal (Digha), India. Approach: The culture dependent method was used for isolation and characterization of novel microbes from the point of biotechnological application. The isolate obtained was … …OnLine Journal of Biological Sciences, Vol. 8, Issue 1 · 31 Mar 2008 · 7,187 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Method to Estimate Intrinsic Parameters in the Ping-pong Bisustrate Kinetic: Application to the Oxipolymerization of PhenolJosé L. Gómez, Antonio Bódalo, Elisa Gómez et al.A new method for determining the intrinsic parameters of reaction in processes involving a high initial rate has been developed. The usefulness of this alternative, which consists of determining several sets of apparent parameters at different times and then extrapolating these to time zero, is demonstrated proved by the linear dependence obtained between the apparent parameters and the reaction time. … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,531 accessesView PDFCite
