Research ArticleOpen accessIn the abstractPerformance Comparison of Two On-demand Routing Protocols for Ad-hoc Networks based on Random Way Point Mobility ModelGeetha Jayakumar, G. GopinathAd hoc networks are characterized by multihop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols plays an important role. We compare the performance of two prominent on-demand routing protocols for mobile ad hoc networks: Dynamic Source Routing (DSR), Ad Hoc On-demand distance Vector Routing (AODV). A detailed simulation model with MAC and physical layer … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,693 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison Effects of Sucrose and Date Palm Syrup on Somatic Embryogenesis of Date Palm (Phoenix dactylifera L )Abdullatif AlkhateebThe effect of different concentration of date palm syrup (2, 4, 6, 8 and 10%) and sucrose at concentration of 30 and 60 g/l in addition to the control (without carbon source) on the micro propagation of date palm "cv. Suckary" were investigated. The results indicated that date syrup was taken up from the media as shown by the increase … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 1 · 31 Mar 2008 · 7,987 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Benthic Fauna in the Discharge Lagoon of a Shrimp Farm With Special Emphasis on the PolychaetesLuis Rafael Martínez Córdova, Luis Fernando Enríquez OcañaA study of benthic fauna, with special emphasis on polychaetes, was made in the discharge lagoon of an experimental shrimp farm and a pond of the farm. The discharge lagoon was divided into three sections and stocked with shrimp at low density (6 Pl/m2). Neither formulated feed nor fertilization was used in these sections. The control pond was stocked with … …OnLine Journal of Biological Sciences, Vol. 7, Issue 1 · 31 Dec 2007 · 6,684 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Bacillus subtilis 'PB6' (ATCC - PTA 6737) on Clostridium difficile Associated Diarrhea (CDAD) and Inflammatory Bowel Disease (IBD) in Animal ModelsEric Peys, Jerry Varghese, Ponusami Suresh et al.The administration of probiotic bacteria is emerging as a potential means of preventing the onset or recurrence of Clostridium difficile associated diarrhea (CDAD) and of attenuating inflammatory activity and preventing relapses in inflammatory bowel disease (IBD). We evaluated the efficacy of Bacillus subtilis 'PB6' (ATCC - PTA 6737) in a hamster model of antibiotic-induced CDAD and in a rat model … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 7,102 accessesView PDFCite
Research ArticleOpen accessIn the abstractHIV Prevention Intervention Outcome among Minority Adolescents in Court Mandated Drug TreatmentJessy Devieux, Robert C. McMahon, Rhonda Rosenberg, Robert M. MalowProblem statement: Delinquent adolescents with substance abuse disorders frequently engage in behaviors that elevate their risk of contracting HIV. Although effective risk reduction interventions are urgently needed, there is uncertainty about the nature of interventions required to produce change. Approach: This study evaluated whether Modified version of Becoming A Responsible Teen (M-BART) produced greater reductions in drug use and sexual … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 6,342 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Azadirachta indica on Sheep Infected Naturally with HelminthesF.R. Macedo, H. Louvandini, G.R. Paludo et al.The objective of this study was to evaluate the effects of neem (Azadirachta indica) on natural helminthes infection in lambs. Forty, four-month-old entire Santa Ines lambs were grazed on pasture, over a 20 week period. They were divided into 4 treatments: Without drenching (ND), 3 g A. indica/animal (A3), 6 g A. indica/animal (A6) and 9 g A. indica/animal (A9) … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 6,678 accessesView PDFCite
Research ArticleOpen accessIn the abstractStandard Versus Specific Therapy for Chronic Osteomyelitis TreatmentAngela Ingianni, Giorgio Lampis, Samuela Laconi et al.58 patients with chronic osteomyelitis were treated either with a standard therapy or with a specific targeted therapy based on the antibiogram assay. Standard therapy was performed by a 15-day course of a parenteral cephalosporin (usually ceftriaxone) in combination with an aminoglycoside (e.g. netilmicin), followed by oral therapy with a fluoroquinolone (generally ciprofloxacin) for 1 to 3 months; specific therapy … …American Journal of Infectious Diseases, Vol. 3, Issue 3 · 30 Sep 2007 · 6,879 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlow Characteristics in Elastic Arteries Using a Fluid-Structure Interaction ModelH. Niroomand Oscuii, M. Tafazzoli Shadpour, Farzan GhalichiIn this study the interaction of blood flow with arterial wall has been investigated using FSI (Fluid-Structure Interaction) modeling. Computer simulation of pulsatile blood flow was carried out on the basis of the time dependent axisymmetric Navier-Stokes equations for an incompressible Newtonian fluid flow. An elastic incompressible material with large deformation was considered for the arterial wall and momentum and … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,432 accessesView PDFCite
Research ArticleOpen accessIn the abstractBeta-2-Microglobulin in Autism Spectrum DisordersPaula Goines, Joseph Schauer, Luke Heuer et al.Autism spectrum disorders (ASD) are heterogeneous neurodevelopmental diseases of unknown etiology. There are no biological markers for ASD and current diagnosis is based on behavioral criteria. Recent data has shown that MHC I, a compound involved in adaptive immune function, is also involved in neurodevelopment, synaptic plasticity and behavior. It has been suggested that altered MHC I expression could play … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 7,565 accessesView PDFCite
Research ArticleOpen accessIn the abstractHow Youth in India and Lebanon Rate their IntelligenceRamzi Nasser, Sushila SinghalA sample of 648 Lebanese and 252 Indian students estimated their intelligences based on Gardner's 10 multiple intelligence. Males rated higher their body kinesthetic and religious dimension (spiritual) while females rated higher their verbal and intra-personal estimates of intelligence. Using the educational level of the parent, no significant correlation with self-estimates of intelligence for each of the national samples was … …Journal of Social Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 7,097 accessesView PDFCite
