Research ArticleOpen accessIn the author namesEvaluation of Some Vaccination Programs in Protection of Experimentally Challenged Broiler Chicken against Newcastle Disease VirusMousa A. Ayoub, Wael K. Elfeil, Diaa El Boraey et al.The current study was carried out to evaluate efficiency of different vaccination programs in protecting broiler chicken against Virulent Viscerotropic Strain of Newcastle disease virus. Different live and inactivated NDV vaccines were used throughout the experiment including; ND-HB1,Elite, LaSota, Inactivated GII and Inactivated GVII. Broiler chicks were divided into 8 groups; 6 groups undergo different vaccination programs against NDV while … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 3 · 16 Sep 2019 · 8,404 accessesView PDFCite
Research ArticleOpen accessIn the author namesA Survey Study on Productive and Reproductive Performance of Indigenous PoultryPeter Ayodeji Idowu, Maliviwe Mpayipheli, Voster MuchenjeA survey study was conducted to analyze the reproductive and productive performances of four indigenous chicken breeds (Potchefstroom Koekoek, Venda, Naked Neck and Ovambo) under different rearing system. Six villages located in Eastern Cape, South Africa were used for the study from July 2017 to June 2018. Data on Clutch Per Year (CPY), hatchability (HATCH), Egg Per Clutch (EGC), survivability … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 1 · 27 Feb 2019 · 9,177 accessesView PDFCite
Research ArticleOpen accessIn the author namesAn Elite Pool-Based Big Bang-Big Crunch Metaheuristic for Data ClusteringIbrahim Al-Marashdeh, Ghaith M. Jaradat, Masri Ayob et al.This paper delves into the capacity of enhanced Big Bang-Big Crunch (EBB-BC) metaheuristic to handle data clustering problems. BB-BC is a product of an evolution theory of the universe in physics and astronomy. Two main phases of BB-BC are big bang and big crunch. The big bang phase involves a creation of a population of random initial solutions, while in … …Journal of Computer Science, Vol. 14, Issue 12 · 19 Jun 2018 · 7,885 accessesView PDFCite
Research ArticleOpen accessIn the author namesCost Effective Expa-Max-Min Scientific Workflow Allocation and Load Balancing Strategy in Cloud ComputingJames Kok Konjaang, Fahrul Hakim Ayob, Abdullah MuhammedThe rise in demand for cloud resources (network, hardware and software) requires cost effective scientific workflow scheduling algorithm to reduce cost and balance load of all jobs evenly for a better system throughput. Getting multiple scientific workflows scheduled with a reduced makespan and cost in a dynamic cloud computing environment is an attractive research area which needs more attention. Scheduling … …Journal of Computer Science, Vol. 14, Issue 5 · 13 Jan 2018 · 8,589 accessesView PDFCite
Research ArticleOpen accessIn the author namesPetrography and Geochemistry of Orin-Ekiti Basement Rocks, Southwestern Nigeria: Implications on BauxitizationAbel Ojo Talabi, Akin Ojo Oyinloye, Olusola Amos Olaolorun et al.The petrography and geochemistry of Orin-Ekiti Basement rocks were evaluated to determine their mineralogical and chemical composition, assessed their petrogenesis and susceptibility to the formation of bauxitic clay. Ten representative rock samples were selected for thin section petrography and bulk rock geochemical analysis using Petrographic microscope and XRF, Rh Tube, 3k Watt respectively. Field observations revealed charnockites as the dominant … …American Journal of Applied Sciences, Vol. 15, Issue 4 · 1 Jan 2018 · 8,769 accessesView PDFCite
Research ArticleOpen accessIn the author namesModelling the Error Term of Australia Gross Domestic ProductAyodele Abraham Agboluaje, Suzilah Ismail, Chee Yin YipThe main aim of this study is to model the Gross Domestic Product (GDP) with the new Combine White Noise (CWN) Model and compare the results with the Vector Autoregressive (VAR) Model and Exponential Generalized Autoregressive Conditional Heteroscedasticity (EGARCH) Model which are the existing models. The CWN model estimation yields best results with least information criteria and high log likelihood … …Journal of Mathematics and Statistics, Vol. 12, Issue 4 · 2 Nov 2016 · 6,932 accessesView PDFCite
Research ArticleOpen accessIn the author namesModeling the Error Term by Moving Average and Generalized Autoregressive Conditional Heteroscedasticity ProcessesAyodele Abraham Agboluaje, Suzilah bt Ismail, Chee Yin YipThis study has been able to reveal that the Combine White Noise model outperforms the existing Generalized Autoregressive Conditional Heteroscedasticity (GARCH) and Moving Average (MA) models in modeling the errors, that exhibits conditional heteroscedasticity and leverage effect. MA process cannot model the data that reveals conditional heteroscedasticity and GARCH cannot model the leverage effect also. The standardized residuals of GARCH … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 20 Nov 2015 · 6,726 accessesView PDFCite
Research ArticleOpen accessIn the author namesSOUND AND VIBRATION CONSIDERATIONS OF SOME MATERIALS FOR AUTOMOTIVE ENGINEERING APPLICATIONSMohammad Al-Zubi, Emmanuel Ayorinde, Nabeel Alshabatat et al.Vibration and noise amelioration in and across several components and modules of the automotive, such as the panels, doors, engine covers, seats and others, is extremely important. NVH performance has been recognized as a critical factor in the purchase decisions of many buyers. This study examines the vibro-acoustic characteristics of some monolithic and composite materials and some generally periodic material … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 2 Dec 2014 · 6,491 accessesView PDFCite
Research ArticleOpen accessIn the author namesTHE IMMUNOMODULATORY EFFECTS OF PROBIOTIC BACTERIA ON PERIPHERAL BLOOD MONONUCLEAR CELLS (PBMCS) OF ALLERGIC PATIENTSSomaya M. El Sheikh, Mona A.M. Shalaby, Raghda A. Hafez et al.Allergic diseases represent major health burden. An allergic reaction is characterized by a disrupted T- helper 1⁄T-helper 2 balance toward a preferential allergen specifically induced TH2 cytokine profile, causing allergic inflammation Probiotic bacteria have various benificial effects in many pathologic situation. Studies have shown that the bacteria present in the intestinal micro flora play a role in the TH1/TH2 balance … …American Journal of Immunology, Vol. 10, Issue 3 · 10 Sep 2014 · 8,276 accessesView PDFCite
Research ArticleOpen accessIn the author namesDesign, Development and Numerical Analysis of Honeycomb Core with Variable Crushing StrengthShabnam Sadeghi Esfahlani, Hassan Shirvani, Ayoub Shirvani et al.A honeycomb core with half-circular cut-away sections at the spine (the adjoining cell walls) is designed and developed and numerically tested under axial dynamic load condition. The parametric study is invoked to identify the effect of various circular cut-away dimensions. In one embodiment a half-circular shaped cuts are removed from the top of the cell where the cell is impacted … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 15 Jan 2013 · 7,577 accessesView PDFCite
