Research ArticleOpen accessIn the abstractChange in Growth Performance and Liver Function Enzymes of Broiler Chickens Challenged with Infectious Bursal Disease Virus to Dietary Supplementation of Methionine and ThreonineElham Maroufyan, Azhar Kasim, Seyed Reza Hashemi et al.Problem statement: The aim of this study was to verify the effects of methionine and threonine supplementations higher than the NRC recommendation on growth performance, liver function enzymes, blood parameters and immune tissues of broiler chickens challenged with infectious bursal disease. Approach: A total of 450 day-old male broiler chicks were assigned to nine groups. Chickens were fed by three … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 9,469 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling of an Industrial Riser in the Fluid Catalytic Cracking UnitMehran Heydari, Habib Ale Ebrahim, Bahram DabirProblem statement: The aim of this study is to obtain a model that can simulate the performance of an industrial fluid catalytic cracking unit in steady state. Approach: The reactions in the riser occur in a transported bed with the fluid and the solids in ideal plug flow. One of the main advantages of the model is that it does … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 8,117 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Seven-Lump Kinetic Model in the Fluid Catalytic Cracking UnitMehran Heydari, Habib AleEbrahim, Bahram DabirProblem statement: The effective simulation of the Fluid Catalytic Cracking (FCC) operation requires a good understanding of many factors such as, reaction kinetic, fluid dynamics and feed and catalyst effects. Approach: In this model the reactor has been considered as an isothermal riser. The reactions in the riser occur with the fluid and the solids in ideal plug flow. Because … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,607 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of L-Leucine Supplementation on Growth Performance and Carcass Characteristics of Grower-Broiler Chickens Fed Low Protein DietsE. Erwan, A. R. Alimon, A. Q. Sazili et al.Problem statement: Supplementation of broiler diets with cristalline amino acids (i.e. lysine, ethionine and threonine) may support equal broiler growth and improve overall amino acids balance and enable a reduction in CP level of diets. Approach: A trial was conducted to evaluate the effect of supplemental L-leucine in diets containing recommended levels and low crude protein (20 and 18%, respectively) … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,965 accessesView PDFCite
Research ArticleOpen accessIn the abstractGrowth, Feed Utilization and Haematology of Clarias gariepinus (Burchell,1822) Fingerlings Fed Diets Containing Different Levels of Vitamin CM. Adunni Adewolu, O. Olakunle AroProblem statement: In an effort to increase growth, improve feed utilization, reduce stress and prevent certain diseases, a 14 week feeding trial was conducted to determine the effects of different levels of dietary vitamin C (ascorbic acid) on growth, feed utilization and hematological changes in Clarias gariepinus fingerlings. Approach: Diets were formulated to contain 0, 50, 100, 150, 500, 1000 … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 7,698 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtilization of Soft Wood Wastes as a Feed Stock to Produce Fuel EthanolAdnan M. Khalil, Ali F. Al-Shawabkeh, Ayman S. Mazahreh et al.Problem statement: The current research investigated the utilization of soft wood waste as a feedstock to produce a value-added product-fuel ethanol. Approach: The main issue in converting soft wood waste to fuel ethanol is the accessibility of the polysaccharides for breaking down into monosaccharides. This study focused on the use of steam as the pretreatment method. The governing factors for … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,628 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Reduced- Protein Diets at Constant Total Sulfur Amino Acids: Lysine Ratio on Pullet Development and Subsequent Laying Hen PerformanceFariborz Khajali, M. Faraji, Saeid Karimi DehkordiThe effect of using a low protein regime in pullet development and subsequent layer performance was studied. The experiment consisted of two periods of rearing and laying. Two hundred and sixty Hy-line W36 chicks were used. In the rearing period, dietary protein level and ME content series of the control group used during starter (18-42), grower (43-63) and developer (64-119d) … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe 2D Eulerian Approach of Entrained Flow and Temperature in a Biomass Stratified Downdraft GasifierA. Rogel, Jasni AguillónThis paper describes a “1-D+2-D” numerical model used to simulate the gasification of pine wood pellets in a stratified downdraft gasifier whereby Eulerian conservation equations are solved for particle and gas phase components, velocities and specific enthalpies. The model takes into account the biomass particle process such as heating up, drying, primary pyrolysis of biomass, secondary pyrolysis of tar, homogeneous … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 7,252 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment on Biocides Bioaccumulation in Mullet Liza klunzingeri in Kuwaiti Waters, off the Arabian GulfA.H. Bu-Olayan, B. V. ThomasBiocides, such as formaldehyde (HCHO), sodium hypochlorite (NaOCl) and glutaraldehyde (C5H8O2) that are commonly used in thermal, desalination and power plants and industries were tested on the commercially important mullet fish, Liza klunzingeri to determine the environmental contamination in the stressed ecosystem of Kuwait Bay sites. Multi-factor Probit analysis toxicity tests (96 h) on L. klunzingeri showed the lowest observed … …American Journal of Environmental Sciences, Vol. 2, Issue 3 · 30 Sep 2006 · 6,768 accessesView PDFCite
Research ArticleOpen accessIn the abstractCombined Partial Oxidation and Carbon Dioxide Reforming Process: A Thermodynamic StudySompop JarungthammachoteProblem statement: CO2 reforming is one of the methods to utilize a greenhouse gas to produce syngas, an important feed for methanol and Fischer-Tropsch synthesis. However, CO2 reforming is strong endothermic reaction requiring large amount of supplied energy. Partial oxidation, an exothermic reaction, is combined with CO2 reforming to serve the energy requirement. Thus, the optimum ranges of O2 and … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,527 accessesView PDFCite
