FongActive research and development of hydrogen-fuelled engine had been done for a few decades since hydrogen serves as a potential of infinite fuel supply. This paper discussed analytically and provides data on effects of compression ratio, equivalence ratio and spark timing of a hydrogen-fuelled engine as a guideline for the engine design. The change in the thermodynamic properties of the … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,886 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPotential of Rice Husk and Rice Husk Ash for Phenol Removal in Aqueous SystemsA. H. Mahvi, A. Maleki, A. EslamiThe potential of rice husk and rice husk ash for phenol adsorption from aqueous solution was studied. Batch kinetics and isotherm studies were carried out under varying experimental conditions of contact time, phenol concentration, adsorbent dose and pH. Adsorption equilibrium of rice husk and rice husk ash was reached within 6 hours for phenolic concentration 150-500 μg/L and 3 hours … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 10,171 accessesView PDF Cite

EditorialOpen accessIn the abstractThe Food Additives Nitrite and Nitrate and Microbiological Safety of Food ProductsStefanie Müller-Herbst, Anna Mühlig, Jan Kabisch et al.In Germany, raw sausages are typically produced according to a technology referred to as hurdle technology (Leistner, 2000). The combination of several stressful conditions should successfully inhibit growth and survival of pathogenic bacteria, which can be regularly found in raw pork or beef material (Mataragas et al., 2008; Rhoades et al., 2009). Hurdles applied during raw sausage fermentation are the … …Current Research in Microbiology, Vol. 6, Issue 1 · 29 Jun 2015 · 10,378 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExperimental and Skeletal Kinetic Model Study of Compressed Natural Gas Fueled Homogeneous Charge Compression Ignition EngineP. M. Diaz, B. Durga Prasad, D.S. Manoj Abraham, K. PalaniKumarProblem statement: In homogeneous charge compression ignition engines fuel oxidation chemistry determines the auto-ignition timing, heat release, reaction intermediates and the ultimate products of combustion. To shorten development time and to understand combustion processes, the use of simulation is increasing. Approach: A model that correctly simulates fuel oxidation at these conditions would be a useful design tool. Detailed models of … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 22 Mar 2012 · 7,255 accessesView PDF Cite
