Research ArticleOpen accessIn the abstractEquilibrium Kinetics and Isotherm Studies of Cu (II) Adsorption from Waste Water onto Alkali Activated Oil Palm AshZaira Zaman Chowdhury, Sharifuddin Mohd. Zain, Rashid Atta Khan, Abdulbari Abdulrahman AhmedProblem statement: Heavy metal accumulation in waste water could affect aquatic life, human health and overall ecosystem adversely. Therefore, in recent years much emphasis has been given for the use of industrial waste material as low cost adsorbents for removal of metallic contaminants from waste water. Approach: Present study deals with the adsorption equilibrium and kinetics of Cu (II) cation … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,933 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDifferent Sorption Approaches and Leachate Fluxes Affecting on Mn2+ Transport through Lateritic AquiferSrilert Chotpantarat, Chakkaphan SutthiratProblem statement: Contamination of the underlying aquifer beneath a mining area is usually of great concern even when a prevention plan has been implemented. Approach: To assess the potential risk of heavy metal contamination, the simulation of heavy metal transport was carried out with different leachate fluxes and sorption parameters derived from equilibrium models with linear and Langmuir isotherms and … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 6,145 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPhysiologic Human Fluids and Swelling Behavior of Hydrophilic Biocompatible Hybrid Ceramo-Polymeric MaterialsAversa Raffaella, Relly Victoria V. Petrescu, Apicella Antonio, Florian Ion T. PetrescuAll synthetic and natural materials to be used in biomedical applications that involve the contact with human body need to be investigated for their physical and chemical modification induced by the human physiological fluids contact and sorption. The development and testing in human physiological equivalent fluids of new hybrid biomaterials are presented. The role of water and its equilibrium modification … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 8 Nov 2016 · 8,387 accessesView PDF Cite

EditorialOpen accessIn the abstractAn Opportunity for the Agricultural Sector: The Renewable Energy SourcesRiccardo Testa, Salvatore TudiscaToday, among the most important issue for energy decisions by policymakers, there are security challenges and environmental impacts on climate change and economic aspects. Since the seventies, in fact, global warming and environmental issues have had an increasing importance in international debate, attracting the attention of several scientific studies (Landi and Benelli, 2016). Many of these studies denoted that over … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 3 · 6 Sep 2016 · 8,092 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRegeneration of Lyes for Cleaning-In-Place (CIP) Processes in Dairies: Comparison of Recycled Potash and Soda Solutions Cleaning PropertiesMarie Furic, Anne Elain, Walid Blel, Olivier SireThe regeneration of lyes for their integration in the dairy CIP was investigated applying an original process combining adsorption/coagulation and flocculation operations. Solutions of potassium hydroxide (KOH) and caustic soda (NaOH) soiled with 1% (v/v) of whole milk were submitted up to twenty successive regeneration cycles. The multiple recycling of the regenerated solutions was found to modify their physicochemical characteristics … …American Journal of Applied Sciences, Vol. 12, Issue 5 · 6 Jul 2015 · 6,624 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDetermination of the Exergy of Four Wheat StrawsYaning Zhang, A. E. Ghaly, Bingxi LiExergy is a measurement of how far a certain material deviates from a state of equilibrium with the environment. It is a useful tool for improving the efficiency of energy-resource use. The exergy values of four wheat straws (Absolvant, Max, Monopol and Vuka) were determined in this study. The effects of physical and chemical properties (moisture content, ash content, LHV … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 7,493 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComprehensive Investigation into the Exergy Values of Six Rice HusksYaning Zhang, A.E. Ghaly, Bingxi LiExergy is a measurement of how far a certain system or material deviates from a state of equilibrium with the environment and it is a useful tool for improving the efficiency of energy-resource use. Based on the previous work, the exergy values of six rice husks were investigated in this study. The effects of physical and chemical properties were also … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 2 · 10 Jun 2013 · 7,596 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
