Research ArticleOpen accessIn the abstractEvaluating the Green Suppliers of the Printed Circuit Board Factories Base on the Fuzzy Analytic Hierarchy Process and Vlsekriterijumska Optimizacija I Kompromisno ResenjeJun-Yuan Kuo, Ben-Chang Shia, Yun-Chin Chen, Jou-Ying HoProblem statement: The “Energy Policy for Europe, EPE” and three environmental directives, proposed by the European Union (EU) in 2007, are stricter than those self-restrained by the enterprises. For this reason, the enterprises have to shortly improve their products for meeting with the strict requests setup by the EU. Consequently, it becomes even more important that the manufacturers evaluate the … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,882 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeat-Modeling of Microwave Assisted Epoxidation of Palm Acid OilN. Saifuddin, L. Wei Zhan, K. Xin NingProblem statement: While microwave chemistry could well be the most convenient, rapid and energy-saving way to initiate a chemical reaction, the issues of thermal versus microwave specific effect remain unaddressed. Approach: A three-dimensional Finite Element Model (FEM) was developed to predict temperature profile during the enzymatic epoxidation of palm acid oil using microwave heating. Three-dimensional partial differential equations are formulated … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,678 accessesView PDFCite
Research ArticleOpen accessIn the abstractCapturing Biogas: A Means to Reduce Green House Gas Emissions for the Production of Crude Palm OilS. Vijaya, A.N. Ma, Y. M. ChooProblem statement: The Malaysian oil palm industry is an important industry to the nation. In 2009 alone the total export earnings reached RM 49.6 billion. The industry is under constant attack of its performance from the perspective of the environment, especially with regard to its Green House Gas (GHG) Emissions. Being an export orientated industry; this issue has to be … …Current Research in Geoscience, Vol. 1, Issue 1 · 30 Jun 2010 · 14,394 accessesView PDFCite
Research ArticleOpen accessIn the abstractSustainable Housing RenewalM. Sitar, K. KrajncFollowing the already proved models the sustainable planning culture is endangering several methods directed towards the needs of tenants in the existing post-war housing stock. The case-study of our project is the renewal of the multi stored building in the housing estate Metalna, Maribor/Tezno (1949). It is based on the sustainable renovation principle for the quality of sustainable housing in … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 7,252 accessesView PDFCite
Research ArticleOpen accessIn the abstractMixing Patterns and Residence Time Determination in a Bubbling Fluidized Bed SystemA. E. Ghaly, K. N. MacDonaldFluidized bed gasification can be used to convert the solar energy stored as carboneous compounds in biomass into a carbon neutral fuel with reduced emissions. Canada produces 20.57 million tonnes of wheat straw annually which could be used for green energy production. Wheat straw residue gasification has the capability of replacing 7.5 % (0.62 EJ) of Canada’s annual fossil fuel … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 17 Aug 2012 · 8,119 accessesView PDFCite
EditorialOpen accessIn the abstractRe-Paving the Road Built by Chemistry: A Challenge to Biochemistry and BiotechnologyAlberto A. IglesiasBiochemistry’s birth can be placed at the end of the nineteenth century, when Eduard Buchner made a clever interpretation of experimental observations on the generation of gas bubbles after addition (the original purpose was preservation) of sucrose to a yeast crude extract (Lagerkvist, 2005). Intelligently, Buchner concluded that the disaccharide had been fermented by broken cells’ suspension to produce CO2, … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 26 Jan 2015 · 7,468 accessesView PDFCite

Research ArticleOpen accessIn the abstractLIFE CYCLE ASSESSMENT FOR OIL PALM BASED PLYWOOD: A GATE-TO-GATE CASE STUDYM. Shamim Ahmad, Vijaya Subramaniam, Halimah Mohammad et al.Life Cycle Assessment (LCA) is an important tool for identifying potential environmental impacts associated with the production of palm based plywood. This study is to make available the life cycle inventory for gate-to-gate data so that the environmental impact posed by oil palm based plywood production can be assessed. Conducting an LCA on the palm based plywood that are derived … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 15 Mar 2014 · 9,080 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance of Thin-Film as Wavelength Filter in Wdm-Pof NetworkMohd Syuhaimi Ab. Rahman, L. S. Supian, Hadi Guna et al.Problem statement: Huge capacity for data transmission and bandwidth are becoming a need nowadays. High cost of implementation using optical fibers prevents utilization of the technology as wide as possible. Approach: Wavelength Division Multiplexing (WDM) was a technique that offers the solution for providing better bandwidth. WDM technique allows several signals that have different wavelengths to be transmitted in a … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 9 Dec 2011 · 7,271 accessesView PDFCite
