Research ArticleOpen accessIn the abstractExperimental Investigation of Cluster Bed-Form Formation Over Uniform SedimentMasoud Karbasi, Mohammad H. Omid, Javad FarhoudiProblem statement: Cluster microforms are a type of small scale bed-form found in the surface layer of some gravel bed rivers. These bed-forms are comprised of discrete, organized groupings of particles that sit above the average elevation of the surrounding bed. As part of the structural organization of the bed, clusters are believed to impact the local dynamics of the … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,878 accessesView PDFCite
Research ArticleOpen accessIn the abstractEco-Friendly Synthesis of Fucoidan-Stabilized Gold NanoparticlesKriengsak Lirdprapamongkol, Warangkana Warisnoicharoen, Suwicha Soisuwan, Jisnuson SvastiProblem statement: Metallic gold nanoparticles (AuNPs) are widely used in many applications including medical, pharmaceutical, diagnostics and sensors. The chemical synthesis of AuNPs normally requires synthetic materials which might cause the toxicological concerns. The use of naturally occurring materials like fucoidans for successful synthesis of AuNPs is of interests. Approach: Fucoidans as sulfated polysaccharides from marine algae Cladosiphon okamuranus (o-fucoidan) … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 9,630 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Morphological Method for Detection and Recognition of Vehicle License PlatesS.H. Mohades Kasaei, S.M. Mohades Kasaei, S. A. MonadjemiProblem statement: License plate detection and recognition is an image-processing technique used to identify a vehicle by its license plate. This notable technology has got multiple applications in various traffic and security cases. To name but a few, toll roads, border control, security and car tracking are same of its applications. The main stage is the isolation of the license … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 7,656 accessesView PDFCite
Research ArticleOpen accessIn the abstractMorphological Characteristics and Pathogenicity of Synchytrium psophocarpi (Rac.) Baumann Associated With False Rust on Winged BeanAbdollah Karami, Zainal Abidin Mior Ahmad, Kamaruzaman SijamProblem statement: Winged bean (Psophocarpus tetragonolobus L.) is an important tropical legume in countries like Malaysia due to its potential as a high protein value crop. However, bright-orange pustules observed on the veins of young leaves, stems, pods and sepals depict symptoms of false rust disease on beans. The causal agent of this disease has been found to be Synchytrium … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 9,581 accessesView PDFCite
Research ArticleOpen accessIn the abstractStressors Influence on Salmonella enterica Serovar Enteritidis Colonization in BroilersE. S. Soliman, E. Taha, K. D. Infante et al.Problem statement: Poultry industry usually exposing birds to a variety of actions and stressors includs fasting for gastrointestinal emptying before transportation and where birds are often exposed to high environmental temperature during the summer months. These environmental stressors may have influences on bird performance and susceptibility to pathogens such as Salmonella enteritidis by altering the intestinal micrbiota and changes in … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 3 · 12 Sep 2009 · 7,190 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Milling Time on Ni0.5Zn0.5Fe2O4 Compositional Evolution and Particle Size DistributionI. Ismayadi, M. Hashim, A. M. Khamirul, R. AliasProblem statement: This study involved an investigation to ascertain the diffusion of NiO and ZnO into the tetrahedral and octahedral sites using mechanical alloying method. The effect of mechanical alloying towards particle size was also reported. Approach: NiO, ZnO and Fe2O3 precursors were mechanically alloyed to synthesis ultrafine powders of Ni0.5Zn0.5Fe2O4. Various milling times were employed to study the effect … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 8,001 accessesView PDFCite
Research ArticleOpen accessIn the abstractScale Formation Due to Water Injection in Malaysian Sandstone CoresAmer Badr Bin Merdhah, Abu Azam Mohd YassinProblem statement: Scale deposition is one of the most serious oil field problems that inflict water injection systems primarily when two incompatible waters are involved. Approach: This study was conducted to investigate the permeability reduction caused by deposition of calcium, strontium and barium sulphates in sandstone cores from mixing of injected Malaysian sea waters (Angsi and Barton) and formation water … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,630 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).
