Research ArticleOpen accessIn the abstractEffect 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 accessIn the abstractElectromagnetic Assessment on Human Safety of Mobile Communication Base Stations at University of MacauK.H. Chiang, K.W. TamAssessment of the electromagnetic exposure due to the mobile communication base station at University of Macau is presented by two testing scenarios. The first scenario about 20 in-situ measurements and the maximum E-field strength was 2.46 V/m that well below the threshold and compliant to the safety guideline. The second scenario investigates on the distance effect of exposure due to … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 6,752 accessesView PDFCite
Research ArticleOpen accessIn the abstractTreatment of Remazol Brilliant Blue Dye Effluent by Advanced Photo Oxidation Process in TiO2/UV and H2O2/UV reactorsM. Verma, A.E. GhalyAdvanced oxidation processes involving TiO2/UV and H2O2/UV were evaluated for their potential use in decolorization of textile dye effluents. A coil photo reactor, consisting of UV radiation source and a spiral coil coated with TiO2, was used to treat synthetic effluent of Remazol Brilliant Blue dye. The TiO2 coating was performed using the sol-gel technique. The effects of UV radiation, … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 7,813 accessesView PDFCite
Research ArticleOpen accessIn the abstractDecolorization of Remazol Brilliant Blue Dye Effluent by Advanced Photo Oxidation Process (H2O2/UV system)A. S. Mahmoud, M. S. Brooks, A E. GhalyAdvanced photo oxidation processes hold great promise for the improved treatment of textile dye effluent. In this study, the effectiveness of a H2O2/UV system for the decolorization of remazol brilliant blue effluent was investigated by examining the optimum conditions for dye removal in two reactors (coil and conventional). The results showed that the coil reactor had a higher temperature profile … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 8,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractImprovement of the Vertical Dispersion of Pollutants Resulting From Chimneys by Thermosiphon EffectA. O.M. Mahmoud, J. Zinoubi, R. B. Maad, A. BelghithThe dispersion of pollutants, resulting from industrial chimneys, in the surrounding atmosphere made the interest in realizing emitting conditions appears. It also encourages the vertical dispersion of these pollutants. At a given wind velocity, the height of this dispersion is essentially a function of the thermal power and the flow rate at the chimney exit. To improve these qualities, we … …American Journal of Environmental Sciences, Vol. 2, Issue 2 · 30 Jun 2006 · 7,406 accessesView PDFCite
Research ArticleOpen accessIn the abstractInduction of Micronuclei in Mice Lymphocytes Exposed to Microwave and TolueneS. B. Mortazavi, A. Safari, A. Khavanin et al.Increasing applications of microwave radiation are of great concern with regard to public health. Several studies have been conducted detect effects of microwave exposure genetic material leading to negative or questionable results. The Micronucleus (MN) assay which is proved to be a useful method for detection of radiation exposure-induced cytogenetic damage was used in the present study to investigate the … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,614 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of UV-C on Drought Tolerance of Alfalfa (Medicago sativa) CallusAli Akbar Ehsanpour, Roya RazavizadehWater stress and unfavorable climate decrease the growth and development of plant globally. Medicago is a valuable plant as a source of food for animal, foliage and for medicine. Since, Iran is located in a dry area; consequently, the study of plant responses to water stress is important. In this research UV-C radiation was used to induce physiological and genetic … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,805 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhotovoltaic Technology of Electricity Generation for Desert CampingShafiqur Rehman, Ali A. Shash, Omar S. Baghabra Al-AmoudiThis study presents a case study on the utilization of global solar radiation data on horizontal surface to perform economical feasibility of using Photovoltaic (PV) panels with battery backup to meet a small load for a camping site in Saudi Arabia. The analysis considers three scenarios with daily average energy demands of: (i) full load, (ii) 75% load and (iii) … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,922 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Mutual Coupling of Typical Commercial UHF RFID Tags in a High-Density EnvironmentGbamélé Konan Fernand, Akpata Edouard, Assamoi Claude Daniel et al.In the context of high-density passive UHF (Ultra High Frequency) RFID (Radio Frequency Identification) tag technology, the problem of mutual coupling has to be taken into account as one of the performance criteria of UHF RFID systems. In practical applications, mutual coupling changes the intrinsic parameters of the antennas attached to these tags, i.e., the impedance matching of the antenna … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 3 · 14 Oct 2022 · 6,578 accessesView PDFCite
