Research ArticleOpen accessIn the abstractEffect of Size of Heated Obstruction within Room on Three Dimensional Air Flow CharacteristicsAbduljabbar Muttair Ahmed, Mukhtar Ahmad, Abdur RahimProblem statement: This study reported a numerical investigation of three-dimensional turbulent buoyant recirculating flow within a room with heated obstruction. Approach: The study involved the solution of partial differential equations for the conservation of mass, momentum, energy, concentration, turbulent energy and its dissipation rate. These equations were solved together with algebraic expressions for the turbulent viscosity and the heat diffusivity, … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 6,934 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRisk Factors for Bacteremia and Predictors of Mortality of Patients with Bloodstream Infection with Methicillin-Resistant Staphylococcus aureusElcio Bakowski, Sérgio Barsantini Wey, Eduardo Alexandrino Servolo MedeirosThe objective of this study was to evaluate the incidence of infection and the risk factors associated to bacteraemia and mortality due to Methicillin-Resistant Staphylococcus Aureus (MRSA). This cohort study, conducted from August 2004 through November 2005, involved 60 consecutively identified patients with bloodstream MRSA infection.

Research ArticleOpen accessIn the abstractAnalysis of Cross and Single Sided Naturally Ventilated Rooms Using CFDK. Visagavel, P. S.S. SrinivasanNatural ventilation contributes to the improvement of thermal comfort and quality conditions of the internal air, while at the same time it is recognized as a very efficient technique that, when applied properly. The present project refers to the numerical prediction of air velocities in cross and single-sided naturally ventilated rooms, which are considered along with atmospheric zone. Continuity and … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,738 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDesign and Development of a Photovoltaic Power System for Tropical Greenhouse CoolingFaisal Mohammed Seif Al-Shamiry, Desa Ahmad, Abdul Rashid Mohamed Sharif et al.Renewable energy sources like photovoltaic (PV) panels are used today in many applications. Natural ventilation in tropical greenhouse is common method for ventilation, which gives higher inside temperatures compared to the outside temperatures. In addition, this type of ventilation is not enough to reduce high temperature inside the structure in low land areas. Thus the requirement of cooling is increased. … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 8,213 accessesView PDF Cite
