Research ArticleOpen accessPhrase in the titleEffect of γ- ray, Microwave Heating and Solar Irradiation of Apple Juice on Organochlorinated Pesticides ResiduesK. Al-Ismail, S. Herzallah, H. DmoorThis study was conducted to evaluate the effect of solar radiation, microwave heating and γ-irradiation on the Organochlorinated Pesticide (OCP’s) in apple juice. The solar radiation caused a destruction of 20% after 20 hr exposure to sunlight compared to 12% reduction for the tested OCP’s after microwave heating for 10 min. On the other hand, the use of γ-irradiation leads … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,162 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Coupled Mathematical Model for a Temperature Dependant Blood Perfusion in Heterogeneous Biological Tissues during Microwave HeatingE. A. Adebile, B. N. Akintewe, K. M. OwolabiProblem statement: The temperature variation in heterogeneous three layered biological tissues was investigated. Approach: The blood perfusion was considered to be temperature dependent. The heating modalities were taking to go on simultaneously in each of the regions on the one hand and also sequentially in another arrangement. The asymptotic series solution was modified for the three layers and the matching … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 6,576 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSynthesis of Gold (Au) Nanoparticles for Mercury AdsorptionKhairul Sozana Nor Kamarudin, Mawarni Fazliana MohamadProblem statement: Mercury is not only hazardous to human health and the environment but could also attack equipment components resulting in a mechanical failure and gas leakage. Approach: Describes the preparation of various sizes and shapes of Au nanoparticles for mercury adsorption by using polyol method under MW heating. Au nanoparticles have been synthesized by a polyol method under Microwave … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,081 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Ultrasonic/Microwave Assisted Extraction (UMAE) and Rheological Properties of Polysaccharides from Auricularia polytrichaZe Zhang, Xiao Ding, Ziyi Xu et al.Polysaccharides from Auricularia polytricha (APPS) were extracted using Ultrasonic/Microwave Assisted Extraction (UMAE) technology. UMAE conditions of APPS were optimized with Response Surface Methodology (RSM). Rheological properties of APPS were investigated. The results suggested that the optimal UMAE conditions for APPS were ratio of water to raw material 22 (mL/g), extraction time 15.3 min and microwave power 59W. APPS solution exhibited … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 14 Mar 2020 · 7,420 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Novel Thermo-Chemical Treatment on Bending Strength of Laminated GlassAjitanshu VedrtnamThe science of thermal and chemical treatment of glass is well documented. The Laminated Glass (LG) is usually not treated as either treated glass is used during production or lower melting temperature of interlayer does not allow the treatment. The present work reports the novel methods of thermo-chemical treatment of LG having annealed soda lime glass plies. Five thermo-chemical treatments … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 29 Mar 2018 · 6,973 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
