Research ArticleOpen accessEvery word in the titleAtmospheric Moisture Condensation to Water Recovery by Home Air ConditionersAmir Hossein Mahvi, Vali Alipour, Leila RezaeiEarth’s atmosphere contains billion cubic meters of fresh water, which is considerable as a reliable water resource, especially in sultry areas. What is important in this context, how to extract the water, in an economic manner. In order to extract water from air conditioner, no need to spend any cost, because water produced as a by-product and trouble production. This … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 7,929 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleQuality Enhancement of Producer Gas From Cassava Rhizome Using High Temperature Air-Steam Downdraft GasificationWorapot Ngamchompoo, Kittichai TriratanasirichaiHigh Temperature Air-Steam Gasification (HTAG) was performed on a bench-scale downdraft gasifier. A cassava rhizome was used as feedstock for the gasification. Air and steam were utilized as the gasifying agents. The objectives in this study were to study the potential of HTAG technology applied with a downdraft gasifier to improve producer gas quality in terms of Higher Heating Value … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 26 Apr 2013 · 6,856 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMathematical Analysis of How the Electrical Training Center Site is Affected by Air PollutionBassam A. Al-HelouThe study has come to the result that the monitoring site at the Electrical Training Centre (ETC) at Al-Hashimyeh town is exposed to grave pollution that goes beyond Jordanian standards of the ambient air. It has, indeed, shown that Sulfur dioxide (SO2) exceeds the limits and its seasonal concentration matches forward with the average wind speed. SO2 concentration reaches its … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 3 Sep 2012 · 7,116 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSeasonal ARIMA for Forecasting Air Pollution Index: A Case StudyMuhammad Hisyam Lee, Nur Haizum Abd. Rahman, Suhartono et al.Problem statement: Both developed and developing countries are the major reason that affects the world environment quality. In that case, without limit or warning, this pollution may affect human health, agricultural, forest species and ecosystems. Therefore, the aim of this study was to determine the monthly and seasonal variations of Air Pollution Index (API) at all monitoring stations in Johor. … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 14 Feb 2012 · 10,332 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFabrication and Experimental Investigation of PCM Capsules Integrated in Solar Air HeaterMahmud M. Alkilani, Kamaruzzaman Sopian, Sohif MatProblem statement: Thermal Energy Storage (TES) process can reduce the time or rate mismatch between energy supply and energy demand. Organic latent heat materials are suitable to use as storage medium, however, the low thermal conductivity of these materials slow the thermal response during charging and discharging processes. Approach: A solar air heater integrated with (PCM) has been designed, fabricated … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 11 Jan 2012 · 7,596 accessesView PDFCite
