Research ArticleOpen accessIn the abstractGenetic Characterization of a Bovine Breed (Tabapua) Under Artificial Selection Located in the Amazon RegionJose Elivalto Guimaraes Campelo, Marcone Helmer da Silva, Ednaldo da Silva Filho et al.Brazil currently has the biggest commercial bovine cattle population in the world. Several different breeds that come from Europe and India compose it. They are primarily used for dairy and meat production. In Brazil, several high quality genetic background cattle are kept in a condition known as pure breed, meaning no other animal of different genetic background is interbreeding with … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 4 · 30 Jan 2013 · 7,552 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Seroepidemiological Survey of Hantavirus in Ilheus CountyMarcos Lazaro Moreli, Vivaldo Gomes da Costa, Flavia Rubia ParizHantaviral diseases are infections caused by a group of viruses that belong to the genus hantavirus and the family Bunyaviridae. In Brazil, several cases of hantavirus have been detected with the use of serological methods including immunofluorescence and Enzyme-Linked Immunosorbent Assay (ELISA). To date, 1.573 cases have been reported in several states across the country with a fatality rate of … …Current Research in Virology, Vol. 1, Issue 1 · 30 Aug 2012 · 13,382 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydrogeological Prognosis with Regard to Realisation of the New Colle Di Tenda Road TunnelCinzia Banzato, Massimo Vincenzo Civita, Adriano Fiorucci et al.Problem statement: The doubling of Tenda pass road tunnel jointing SW France to Piedmont (Italy) was planned to penetrate a complicate rock structure in which several complex play an hydrogeologic role including carbonate-Karst aquifer between flysch impervious complexes. The main problem of the project is the presence of an hydraulic circulation feeding a spring of social and economic great importance … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 7,363 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling and Optimization of the Vortex Tube with Computational Fluid Dynamic AnalysisK.K. Zin, A. Hansske, F. ZieglerProblem statement: This study illustrated the influence of the Length to Diameter (L/D) on the fluid flow characteristics inside the counter-flow Ranque-Hilsch vortex tube predicted by Computational Fluid Dynamic (CFD) and validated through experiment. Approach: The swirl velocity, axial velocity, radial velocity component and also secondary circulation flow (back-flow) along with the pressure within the vortex tube were simulated and … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,828 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Salivary Electrolytes during Normal Menstrual Cycle with Special Reference to OvulationS. Alagendran, Govindaraju Archunan, Enrique Orozco Bonnila Armando, Rosalinda Guevara GuzmanThere is evidence to imply that estrogen influences salivary electrolytes activity in women. Problem statement: In this study we investigated changes in sodium, potassium and inorganic phosphorus, calcium and magnesium which related to find out the precise day of ovulation. These changes might help to explain the fluctuation of ovarian hormones such as preovulatory estrogen surge. Approach: Human whole saliva … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 8,805 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy on the Thermal Accumulation and Distribution Inside a Parked Car CabinHussain H. Al-Kayiem, M. Firdaus Bin M. Sidik, Yuganthira R.A.L MunusammyProblem statement: When a vehicle is parked under the direct sun, the accumulated heat is affecting many interiors inside the vehicle cabin, such as the vinyl materials of the dashboard, the leather covers and the electronic components. Also, it represents an uncomfortable operating period for the passengers. The studies under this topic are entitled by the vehicle manufacturers as "Vehicle … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 15,508 accessesView PDFCite
