Research ArticleOpen accessIn the abstractAnalysis of Heat Transport in a Proton Exchange Membrane (PEM) Fuel CellE. Afshari, S.A. JazayeriIn this study a two-phases, single-domain and non-isothermal model of a Proton Exchange Membrane (PEM) fuel cell has been studied to investigate thermal management effects on fuel cell performance. A set of governing equations, conservation of mass, momentum, species, energy and charge for gas diffusion layers, catalyst layers and the membrane regions are considered. These equations are solved numerically in … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,343 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThermal Energy Loss in the Steam Valves and its EffectsGalip Temir, Durriye BilgeIn this study, the effects of thermal losses in steam valves for flow have been analyzed. In a set of experiment built to achieve this, pressure and condensate values have been calculated in different temperatures for insulated and non-insulated cases in three different nominal diameter steam valves. The amount of energy lost from the valve surface in the natural convection … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,210 accessesView PDF Cite

Review ArticleOpen accessIn the abstractBiomechanically Inspired Machines, Driven by Muscle Like Acting NiTi AlloysAntonio Apicella, Raffaella Aversa, Florian Ion Tiberiu PetrescuThe Shape of the Memory Alloy (SMA) is a very promising class of metallic materials with interesting non-linear properties such as Pseudo-Elasticity (PE), memory (MEM) and damping capacity due to high mechanical hysteresis and internal friction. Research shows a bioinventory approach to Shape Memory Alloy (SMA) design, a class of intelligent materials capable of reacting to a pulse (thermal for … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 23 May 2018 · 8,288 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordExtrusion of Peas (Pisum sativum L.): Effects on the Apparent Metabolisable Energy and Ileal Nutrient Digestibility of BroilersCatootjie L. Nalle, Ganesharanee Ravindran, Velmurugu RavindranProblem statement: The potential feeding values of grain legumes, such as peas (Pisum sativum), are limited because of the presence of anti-nutritional factors. In particular, protease inhibitors are of interest, but these can be readily destroyed by thermal treatments. In the present study, the influence of extrusion on the chemical composition and nutritive value of peas was evaluated. Approach: Two … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 1 · 26 Apr 2011 · 8,417 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSpraying Effects on Goat Welfare in Hot and Humid ClimateNazan Darcan, Fatin Cedden, Okan GuneyHeat stress is one of the major factors adversely affecting animal welfare and thus economic benefits of farms. This study was designed to determine the effects of three different spraying methods on goats for reducing heat stress. Thirty goats divided into three groups for the trial (One time sprayed a day: OTS, Two times sprayed a day TTS and Non-sprayed: … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,302 accessesView PDF Cite
