Research ArticleOpen accessAll words, across the recordEfficiency of Carica papaya L. Seeds in Anticoccidial Control for Cockerel of Lohmann Brown StrainKomlan Mawouli Wampah, Kosi Mawuéna Novidzro, Namponi Dianam, Abalo Essosimna KuloTo combat avian coccidiosis, chemical products are widely used in poultry farming. However, chemotherapy has inconveniences due to the bioresistance of Coccidia and the presence of undesirable residues in consumer products. The aim of this study is to investigate the toxicity of papaya seeds as a bio-insecticide against Coccidia in Lohmann brown chickens in order to improve their zootechnical parameters. … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 1 · 27 Jan 2024 · 6,659 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEnergy Efficiency Analysis of a TR-UWB SystemAdil El Abboubi, Fouzia Elbahhar, Marc Heddebaut et al.In wireless communications, where sensors operate on batteries, the energy consumption must be reduced while considering the communication range and data rate requirements. In this context we analyze and compare, in this study, the UWB and TR-UWB system in terms of the total energy consumption. So, for that, we develop an analytical model to estimate the energy consumption of a … …Journal of Computer Science, Vol. 12, Issue 1 · 15 Feb 2016 · 7,317 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEVALUATION OF N ADDITIVES FOR IMPROVING N USE EFFICIENCY OF SURFACE APPLIED UREA TO DRY SEEDED AND PERMANENTLY FLOODED RICEDavid D. Dunn, Pawel WiatrakThere are several potential Nitrogen (N) loss mechanisms in a dry seeded and delayed flood system rice (Oryza Satvia L.) production system including urea volatilization and denitrification. The scope and magnitude of these potential losses are largely weather dependent. Two additives (stabilizers), Agrotain and Nutrisphere-N, have been offered to rice producers for controlling these potential losses. This study compared these … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 21 Jun 2014 · 6,692 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Wear of Tunnel Boring Machine Excavation Tools in RockClaudio Oggeri, Pierpaolo OresteSome of the most important aspects in the study of the fragmentation of rock due to the action of TBM disks concern the abrasiveness of the rock and the wear of the tools. The wear of the disks in fact means that they have to be substituted, with consequent effects on the efficiency of the excavation, on the speed of … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 16 Aug 2012 · 7,654 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordValidation of the Ceres-Wheat for Prediction of Wheat Varieties in Irrigation and Terminal Drought StressFarzad Paknejad, Fatemeh Majidi Fakhr, Seied Mehdi MirtaheriProblem statement: Crop growth models have many potential uses for crop managements. Approach: In order to evaluation of CERES-Wheat model on five varieties of winter wheat in Karaj weather condition in Full Irrigation (FI) and Stop Irrigation (SI) after flowering until final growth stage an experiment conducted in shape of split plot in based on randomize complete block design with … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 2 · 16 Mar 2012 · 7,723 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordImprovement of the Runner Design of Francis Turbine using Computational Fluid DynamicsSuthep Kaewnai, Somchai WongwisesProblem statement: The objective of this study is to improve runner design of the Francis turbine and analyze its performance with the Computational Fluid Dynamics (CFD) technique. Approach: A runner design process uses a direct method with the following design conditions: flow rate of 3.12m3/sec head of 46.4 m and speed of 750 rpm or dimensionless specific speed of 0.472. … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 25 Jan 2012 · 8,920 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Comparison between Electrical and Optical Chromatic Dispersion Compensation in Wavelength Divison Multiplexing Network Regarding to Electrical Pulse ShapesMohammad Syuhaimi Ab-Rahman, Majid MoghaddasiProblem statement: Besides of some impairment that has been inherited form single channel, specialists confronted with new obstacles in WDM implementation which bared them for achieving desired performance. Although Chromatic Dispersion (CD) exists in single channel too, it can worsens new nonlinearities which are occurs just in WDM systems. So CD compensation in WDM is even more vital than single … …Journal of Computer Science, Vol. 8, Issue 1 · 29 Oct 2011 · 6,920 accessesView PDFCite
