Research ArticleOpen accessIn the abstractAir-Cooling Used For Metal CuttingBrian Boswell, Behrad Katirachi, Tilak T ChandratillekeAir-cooling and dry machining are both being trialled as possible solutions to the metal cutting industry’s long running problems of extending tool life, reducing tool failure and minimising the heat generation at the tool tip. To date, large amounts of expensive coolant which cause both environmental damage and health hazards have had to be used. The introduction of dry machining … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 8,215 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesigning for Comfort and Reliability in an Intelligent Car SeatD.A. Wahab, N.F. Adull Manan, M.A. Hannan et al.Today, intelligent safety systems are installed in modern cars in view of minimising road hazards. An intelligent air bag system for example, comprised several subsystems that are integrated to include the weight sensor system, image sensor system, crash sensor system and tyre pressure monitoring system. These systems when poorly positioned into the car seat, will certainly affect comfort and reliability … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,601 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 · 7,004 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Ethical Appraisal of Hormesis: Towards a Rational Discourse on the Acceptability of Risks and BenefitsOrtwin RennIt is ethically mandated that potential beneficial aspects of low exposure to potentially hazardous material are incorporated in the risk-benefit balancing procedure. The potential harm done by pollutants does not justify the invocation of a categorical principle. Minimisation of risk is not required if health benefits are also at stake. Society needs to find an informed consent on the threshold … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,080 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review on Construction Technologies that Enables Environmental Protection: Rubberized ConcreteG. Senthil Kumaran, Nurdin Mushule, M. LakshmipathyThroughout the world, the disposal of used tires is a major environmental problem causing environmental hazards such as breeding ground for mosquitoes, producing uncontrolled fire and they are contaminating the soil and vegetation. Therefore, there is an urgent need to identify alternative outlets for these tyres, with the emphasis on recycling the waste tyre. Concrete is an excellent structural material … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,921 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Modelling of an Industrial Smelter Furnace and Converter Off-gas SystemHelen Shang, Megan Dillabough, Phillip Nelson, Bryan SaltIn smelters, metal ores or concentrates are smelted to reduce a metal oxide to a metal through a series of reactions and processes. In a smelting process, a large amount of off-gas emissions are often generated, which can cause serious environmental and plant hygiene problems if not properly treated. Off-gas systems extract and treat the off-gas emissions, and ensure that … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 7,158 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of the Upland Weed Control Potentiality of Green Tea Waste-Rice Bran Compost and Its Effect on Spinach GrowthM.A.I. Khan, K. Ueno, S. Horimoto et al.This study evaluated the upland weed control potentiality, germination inhibition ability and growth suppression efficiency of the five combinations of green tea waste - rice bran compost (GRC). GRC was prepared by mixing green tea waste and rice bran at five ratios, and allowed to decompose for 5 mo. Application of GRC suppressed weed growth up to 93.4% in number … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 8,207 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Role of Quality Control and Everyone’s Participation in Japan to Prevent Pollution During Last Five DecadesMohammed Matouq, Nasir Kloub, Kazue InoueEconomic Growth in Japan after World War II was very remarkable and products from its manufacturing industry were widely accepted in the world market after productivity and quality of them were tremendously improved. On the other hand, Japan soon found itself in severe environmental deterioration, due to not being paid any attention to environment. However, that pollution from industry was … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 30 Apr 2007 · 7,999 accessesView PDFCite
Research ArticleOpen accessIn the abstractRisk Assessment Study for Storage ExplosiveS. Saiful Azhar, M. Abdul Rahman, M. Saari et al.In Malaysia, there has been rapidly increasing usage in amount of explosives due to widely expansion in quarrying and mining industries. The explosives are usually stored in the storage where the safety precaution had given high attention.
