Research ArticleOpen accessIn the abstractPerceptions of Paddy Farmers towards Sustainable Agricultural Technologies: Case of Haraz Catchments Area in Mazandaran province of IranA. Bagheri, H. Shabanali Fami, A. Rezvanfar et al.Sustainable agriculture has defined and described in many ways. Despite the diversity in conceptualizing sustainable agriculture, there is a consensus on three basic dimensions of the concept, namely, ecological soundness economically viable and socially acceptable. The dimensions of ecological soundness refers to the preservation and improvement of the natural environment. Environmental issues emerge from the human use of natural resources. … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,803 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation of Vehicle Flows and Emissions for Various Scenarios of Street Network Modifications in Mexico CityAngelica Lozano, Francisco Granados, Juan Pablo AntunWe estimate flows and emissions (NOx, HC, CO) generated by vehicles circulating on the main streets of the Mexico City Metropolitan Area. The estimation is made for various scenarios, which include a set of changes to the street network for current and future horizons. These changes encompass the construction of new arcs or improvement of existing arcs. Network flows are … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 6,214 accessesView PDFCite
Research ArticleOpen accessIn the abstractGamma Radiosensitivity Study on Chili (Capsicum annuum)Shairul Rizdiyandi Omar, Osumanu Haruna Ahmed, Shaharudin Saamin, Nik Muhamad Ab. MajidInduced mutation by gamma irradiation has been found to be a very useful technique for crop improvement. Apart from this, the proper use of induced mutation in plant breeding has become a profitable approach. This investigation was carried out to determine the LD50 and effect of gamma rays on germination, plant height, survival percentage, root length, root dry weight and … …American Journal of Applied Sciences, Vol. 5, Issue 2 · 28 Feb 2008 · 9,033 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordNumerical Investigation on Performance Improvement in Tube Inserted with Delta Winglets on Discrete Right-Angled Triangular PlatesAmnart Boonloi, Withada JedsadaratanachaiNumerical investigations on flow topology and heat transfer behavior in a round tube heat exchanger inserted with Delta Winglets (DW) on Discrete Right-angled Triangular Plates (DRTP) are performed. The influences of DW heights; b/D or BR = 0.05-0.25 and flow directions; DW with V-Downstream (DWVD) and DW with V-Upstream (DWVU), are studied for turbulent flow; Re = 3000-10,000. The finite … …Journal of Mathematics and Statistics, Vol. 13, Issue 1 · 16 Mar 2017 · 7,049 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordENERGY PERFORMANCE IMPROVEMENT, FLOW BEHAVIOR AND HEAT TRANSFER INVESTIGATION IN A CIRCULAR TUBE WITH V-DOWNSTREAM DISCRETE BAFFLESWithada Jedsadaratanachai, Amnart BoonloiA mathematical study has been carried out to examine periodic laminar flow and heat transfer characteristics in a three-dimensional isothermal wall circular tube with 45° in-line V-discrete baffles. The computations are based on the Finite Volume Method (FVM) and the SIMPLE algorithm has been implemented. The fluid flow and heat transfer characteristics are presented for Reynolds numbers based on the … …Journal of Mathematics and Statistics, Vol. 9, Issue 4 · 23 Nov 2013 · 6,376 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordIMPROVEMENT OF AUTOMATIC HEMORRHAGES DETECTION METHODS USING SHAPES RECOGNITIONNidhal Khdhair El Abbadi, Enas Hamood Al SaadiDiabetic Retinopathy is a medical condition where the retina is damaged because fluid leaks from blood vessels into the retina. The presence of hemorrhages in the retina is the earliest symptom of diabetic retinopathy. The number and shape of hemorrhages is used to indicate the severity of the disease. Early automated hemorrhage detection can help reduce the incidence of blindness. … …Journal of Computer Science, Vol. 9, Issue 9 · 6 Aug 2013 · 6,486 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCytoprotective Effect of UlGen, a Polyherbal Formulation against Physical and Chemical Factor Induced Gastric Ulcers in Wister Albino RatsT. S. Muralidhar, Anna Balaji, Chinmay Bandopadhyay, S. L. ShanthaProblem statement: UlGen, a Polyherbal formulation, was investigated for its possible Ulcero-protective activity in ulcerogen and Cold-restraint stress induced Wister rats (Rattus rattus). Oral administration of UlGen, at a dose of 800 mg kg-1 significantly protected the onset of cold-resistance stress induced ulcerations. Approach: It significantly inhibited gastric ulceration induced by alcohol and aspirin.
