Research ArticleOpen accessIn the abstractValidating Trace Metals Levels in PM2.5 Aerosols from Indoor and Outdoor Polluting PremisesA. H. Bu-Olayan, B. V. ThomasProblem statement: Our studies revealed high trace metals concentrations in PM2.5 aerosols from Residential Buildings (RB-I) and enclosed Car Parks (CP-I) indoor than in outdoor Residential Buildings (RB-O) and Car Parks Outdoor (CP-O), indicating possible dust accumulation in confined premises from six Kuwait Governorate areas. Approach: Trace metals in PM2.5 was high in the sequence of Bed Room (BR) >kitchen … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 7,381 accessesView PDFCite
Research ArticleOpen accessIn the abstractFreshwater Situation in Kuwait-Remote Sensing Inputs on Possibility of Artificial RechargeM. Al-Murad, S. Uddin, A. Al-DousariProblem statement: Kuwait is an arid country having per capita freshwater consumption of 485 l day-1. Almost the entire freshwater requirements are met through desalination. The water tariffs in the country are very low consequent to 60% subsidy provided by the government. The use of tertiary treated wastewater is restricted to irrigation and forestation; this leaves huge surplus that can … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 7,409 accessesView PDFCite
Research ArticleOpen accessIn the abstractSustainable Development through Waste Heat RecoveryP. S. Bundela, Vivek ChawlaProblem statement: Waste Heat Recovery (WHR) steam Technology is a proven Technology pioneered by Japanese for cement plant and it is economically viable. Electrical Power can be generated by adopting the latest technology in this field. It used a medium to low temperature (120-350°C) Turbine technology (standard thermal power plants run on steam temp-500°C). Approach: It requires treat exchangers (Hx) … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,401 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Yellow Mealworm as a Novel Source of ProteinA. E. Ghaly, F. N. AlkoaikProblem statement: Yellow mealworms of different sizes (4.8-182.7 mg) were grown in a medium of wheat flour and brewer’s yeast (95:5 by weight) to evaluate their potential as a protein source. Approach: There was an initial adjustment period (3-9 days) observed during which the younger larvae (4.8-61.1 mg) grew slowly while the older ones (80.3-182.7 mg) lost weight. After this … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 20,859 accessesView PDFCite
Research ArticleOpen accessIn the abstractHard Coal Fly Ash and Silica-Effect of Fine Particulate Matter Deposits on Brassica chinensisChristian Ulrichs, Uwe Schmidt, Tanja Mucha-Pelzer et al.Problem statement: One focus in recent atmospheric pollution research is on fine Particle Matter (PM), especially as result of increasing traffic and anthropogenic activity in urban areas. Here, the impact on animal and human health has been in the center of many studies. Despite the fact that PM depositions can affect plants on the long term, there are only few … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,648 accessesView PDFCite
Research ArticleOpen accessIn the abstractEngineering Properties of Locally Manufactured Burnt Brick Pavers for Agrarian and Rural Earth RoadsEmmanuel Akintunde OkunadeThis study explored the possibility of employing burnt bricks produced locally by completely traditional methods as pavers on unpaved agrarian and rural earth roads in indigent communities. The pavers would eliminate the problems on such roads of being waterlogged and impassible during the rainy season months and those of environmental and health hazards from raised dust during the dry season … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,000 accessesView PDFCite
Research ArticleOpen accessIn the abstractWaste Characterization in Steel Casting and Recycling Opportunities in EuropeSilvia Fiore, Maria Chiara Zanetti, Barbara RuffinoThe wastes coming from a steel foundry located in Italy, producing about 600,000 t/y of steel slabs, are considered in this work. The plant produces about 143,000 t/y of wastes, made of furnace and ladle slags (84%), pelletized dust (8%) and oxidised shaving (8%). The waste materials have been characterised by means of particle-size and chemical analyses, and some reuse/recycle … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 7,049 accessesView PDFCite
Research ArticleOpen accessIn the abstractLightning Over-Voltages on Amman-Aqaba 400 KV LineGhassan Halasa, Ibrahim Badran, Hafez El-ZayyatAn attempt is made to evaluate the lightning over-voltage failure rate for Amman- Aqaba 400kV transmission line by studying the geographical and temporal characteristics of lightning causing the line forced outages. The line was divided into three sections based on weather and pollution conditions. It was found that the line failure rate due to lightning over-voltages is low compared to … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,632 accessesView PDFCite
Research ArticleOpen accessIn the abstractPM Emissions in a Urban ContextEnrico Brizio, Giuseppe Genon, Stefania BorsarelliWithin a urban environment, three different sources of particulate matter should be considered: heating plants using different combustibles (natural gas, gas oil, fuel oil, wood), industrial plants placed in the surrounding area, traffic. While the effects of the first two origins can be easily calculated on the basis of existing emission factors, the PM emissions from traffic are of two … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 6,872 accessesView PDFCite
Research ArticleOpen accessIn the abstractFoundry Wastes Reuse and Recycling in Concrete ProductionSilvia Fiore, Maria Chiara ZanettiThe industrial process of a cast iron foundry plant located in the North of Italy was analyzed in order to determine the amount and kind of produced wastes. The main fractions are core and moulding sands, muds and powders from dust abatement plants, furnace and ladle slags, and exhaust lime, making about 750-800 t/d of residues for a production of … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,952 accessesView PDFCite
