Research ArticleOpen accessIn the abstractThe Effect of Electricity Price on Saving Energy Transmitted from External Building WallsSamah K. Alghoul, Ammar O. Gwesha, Abdurrauf M. NaasSpace heating and cooling loads consume a significant part of the national produced energy in many countries. Therefore, substantial energy savings can be achieved by the reduction of spent energy in this category. Since wall insulation is rarely used in Libya, this research was conducted to study the effect of electricity price on residential heating and cooling energy consumption and … …Energy Research Journal, Vol. 7, Issue 1 · 31 May 2016 · 10,842 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Microwave Pretreatment on BMP of Decanter Cake from Palm Oil Mill FactoryThaniya Kaosol, Worawuth RungarunanotaiAnaerobic digestion is an effective method for treating decanter cake in the biogas production. Decanter cake usage is limited by its slow fiber degradation for anaerobic digestion process. The aim of this study is to study the possibility of using microwave pretreatment to enhance decanter cake digestibility. The power and heating time are the parameters that influence the biogas production … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 23 May 2016 · 7,625 accessesView PDFCite
Research ArticleOpen accessIn the abstractINFLUENCE OF REACTION TEMPERATURE AND REACTION TIME ON PRODUCT FROM HYDROTHERMAL TREATMENT OF BIOMASS RESIDUEJakaphong Kongpanya, Kanokorn Hussaro, Sombat TeekasapThailand is facing with problems associated with biomass residue such as palm oil residues (oil palm trunks, oil palm fronds, empty fruit bunches, shells and fibers). Biomass is promising source for the production of an array of energy-related produts including, liquid, solid and gaseous fuels, heat, chemicals electricity and other materials. Therefore, the use of biomass for energy is not … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 2 Jun 2014 · 7,676 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesigning and Manufacturing of a Non Thermal Milk Pasteurizer Using Electrical FieldAsaad Rehman Saeed Al-HilphyUsing of traditional milk pasteurization methods caused fouling by heat, particularly rapid pasteurization by ohmic heating at 220 volts resulted protein denaturation, when milk holding of 15 sec under ohmic heating at 72°C. So to control these properties a Non-thermal treatment by different electrical fields at 20, 27.5, 55 V/cm (80, 110, 220V, AC) and quickly milk pass between poles … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 3 · 4 Sep 2013 · 7,481 accessesView PDFCite
Research ArticleOpen accessIn the abstractGC-MS Analysis and PLS-DA Validation of the Trimethyl Silyl-Derivatization TechniquesKamalrul Azlan Azizan, Syarul Nataqain Baharum, Habtom W. Ressom, Normah Mohd. NoorProblem statement: Comparison and validation analysis of the conventional and power-adjusted Microwave-Assisted (MA) techniques of TMS derivatization using Gas Chromatography-Mass Spectrometry (GC-MS) and Multivariate Analysis (MVA) of Partial Least Squares Analysis (PLS-DA). Further improvement of the conventional technique using vigorous shaking was tested and analyzed. Approach: Cross-validation and response permutation test of PLS-DA and S-plot of Orthogonal Partial Least Squares … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 4 Jun 2012 · 10,320 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 · 7,676 accessesView PDFCite
