Research ArticleOpen accessIn the abstractZero Geometry, Zero Space Time, The Seeds of The Final TheoryKambiz-AfrasiabiProblem statement: Lack of understanding And scientific formulation of zero geometry and zero space-time and the truth about initiation conditions would continue to keep us all in dark and we would continue to create more theories defining our observations about the known universe which could Indeed be part of our illusionary perception of reality And as long as they continue … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 10 Oct 2011 · 7,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractClinical Signs of Hairballs in Cats Fed a Diet Enriched with CelluloseA. C. Beynen, J. Middelkoop, D. H.J. SarisProblem statement: The intake of cellulose may delay gastric emptying and raise the intestinal transit rate. These effects could antagonize hairball formation. Thus, it was hypothesized that a diet enriched with a cellulose preparation (Arbocel BWW40®), forming a completely insoluble fiber network, would diminish the severity of clinical symptoms of hairballs in cats. Approach: In a double-blind, placebo-controlled trial with … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 2 · 8 Aug 2011 · 11,925 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Different Exogeneous Compounds on Biosorption of EndosulfanDeepika Dave, A. K. DikshitProblem statement: Organochlorine pesticide endosulfan is widely used as a replacement for DDT and dieldrin in many parts of the world. Presence of residual pesticides in the water, air and soil environment was confirmed since 1960s. Such Persistent Organic Pollutants (POPs) are of concern because of their long-term subtle effects on hormones, the immune system and reproduction. Therefore, it becomes … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 7,205 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation of Pathogenic Microorganisms during Atmospheric Tempestat North AfricaU. Ali RahomaProblem statement: Dust continued to blow across northern Africa and the Mediterranean Sea on March 3, 2005. Many sources are associated with areas where human impacts are well documented. Approach: Nonetheless, the largest and most active sources are located in truly remote areas where there is little or no human activity. Dust activity is extremely sensitive to many environmental parameters. … …Current Research in Medicine, Vol. 2, Issue 1 · 29 Mar 2011 · 7,402 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysical Composition, Nutrients and Contaminants of Typical Waste Dumping SitesH. Meuser, K. S. Grewal, R. Anlauf et al.Problem statement: The composition of wastes is quite variable depending upon the generating source and mode of collection. Most of the material from the domestic activities will be organic in nature and contains essential plant nutrients, whereas the dumping material of commercial and industrial wastes usually contains appreciable amounts of heavy and potentially toxic metals and organic pollutants. Approach: Objective … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 7,761 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanical Strength and Durability Properties of High Performance Mortar Containing Densified Silica FumeCheah Chee Ban, Mahyuddin RamliProblem statement: Numerous data and information on pozzolanic reaction and microfiller properties of silica fume were derived from laboratory investigation on silica fume in undensified form. Currently, due to low bulk density of undensified silica fume which poses problem in transportation and handling of the material, silica fume are commercially supplied in densified form. Densification process used to increase bulk … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,958 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Simplified Analytical Modeling of the Hole Erosion TestMohammed Bezzazi, Abdellatif Khamlichi, Miguel Prron Vera et al.Problem statement: Internal erosion occurs in soils containing fine particles under the action of high pressure gradients that could result from water discharge. This phenomenon can yield in its final stage to the formation of piping which constitutes a real threat for hydraulics infrastructures as it can precipitate their entire rupture in very short time. In order to mitigate this … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 30 Nov 2010 · 8,032 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Wall Roughness and Concentration of Clay on Erosion in the Hole Erosion TestKissi Benaissa, Parron Vera Miguel Angel, Rubio Cintas Maria Dolores et al.Problem statement: Internal soil erosion is a real threat for hydraulic infrastructures. In its final stage it develops in piping involving the formation and progression of a continuous void inside the soil between the upstream and downstream sides. The hole erosion test was introduced to characterize kinematics of piping in terms of the time left to rupture. Actual modeling approaches … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 22 Nov 2010 · 8,510 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of a Heavy Duty Chisel Plow at Various Tillage Depth and Forward SpeedsS. A. Al-Suhaibani, A.E. GhalyProblem statement: Tillage is a process of creating a desirable soil condition for seed germination and growth. The tillage of soil is considered to be one of the biggest farm operations as the tillage operation requires the most energy on the farm. Manufacturers of tillage implements tend to overdesign their products due to a lack of the proper testing and … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 8,319 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimizing Coagulation Process for Low to High Turbidity Waters Using Aluminum and Iron SaltsAkbar Baghvand, Ali Daryabeigi Zand, Nasser Mehrdadi, Abdolreza KarbassiProblem statement: Turbid waters, containing colloidal particles, are normally treated by coagulation-flocculation followed by clarification. Ferric chloride and alum, which are the most common types of coagulants in water treatment plants of Iran as well as many other countries, were investigated with the aim of determining their capabilities to reduce turbidity of drinking water. Turbidity was added as kaolin. Optimization … …American Journal of Environmental Sciences, Vol. 6, Issue 5 · 31 Oct 2010 · 21,088 accessesView PDFCite
