Research ArticleOpen accessIn the abstractEngineering of Ground for Liquefaction Mitigation Using Granular Columnar Inclusions: Recent DevelopmentsA. Murali Krishna, M.R. MadhavProblem statement: Liquefaction was the most hazardous damage during an earthquake. Ground improvement techniques were employed to mitigate liquefaction hazards. Most common methods to improve engineering properties of soils are densification, reinforcement, grouting/mixing and drainage. Among various remedial measures available, installation of columnar granular inclusions is the most widely adopted method for liquefaction mitigation. Approach: Columnar granular inclusions function as … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 3 · 30 Sep 2009 · 7,739 accessesView PDFCite
Research ArticleOpen accessIn the abstractCamel's Milk Protects against Aluminum Chloride-Induced Toxicity in the Liver and Kidney of White Albino RatsFahaid Al-HashemProblem statement: Aluminum chloride (AlCl3) is commonly used in daily life but it can be potentially toxic. Therefore, the present study was carried out to investigate the protective effects of camel’s milk against aluminum-induced biochemical alterations and oxidative stress in the liver and kidney of white albino rats. Approach: White albino male rats (230-250 g) were divided into three groups … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 3 · 30 Sep 2009 · 10,376 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of Garbage Sorting MachineStephen Kwasi Adzimah, Simons AnthonyProblem statement: Domestic waste collection, sorting and disposal are major problems in many developing countries such as Ghana. It is an undeniable fact that the environment has been engulfed in filth. This filth comprises of the garbage and waste generated in homes, workplace and industrial setups. Most of this waste has found its way into the streets, gutters, in and … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,520 accessesView PDFCite
Research ArticleOpen accessIn the abstractAlnus subcordata C.A.M. Cambium Cells Dynamics Along Transport Corridors in Hyrcanian ForestsAidin Parsakhoo, Hamid Jalilvand, Mehdi SheikhiProblem statement: In this study, we considered transport corridors and sampling aspects to be the major indicators of ecological effects on Alder (Alnus subcordata) cambium cells dynamics. Approach: Thus, 240 cores were taken from forest-facing and road-facing trunk of Alder trees along Amre, Neka and Darab Kola transport corridors in hyrcanian Forests of Iran. Results showed that the roads corridor … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 6,953 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntifungal Activity of Essential Oils from Some Medicinal Plants of Iran against Alternaria alternateI. Hadizadeh, B. Peivastegan, H. HamzehzarghaniProblem statement: Increasing public concern over the level of pesticide residues in food especially fresh produce has built up adequate pressure for scientists to look for less hazardous and environmentally safer compounds for controlling post harvest diseases. Essential oils as registered food grade materials have the potential to be applied as alternative anti-fungal treatments for fresh fruits and vegetables. Approach: … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 9,810 accessesView PDFCite
Research ArticleOpen accessIn the abstractImprovement on the Design of a Cabinet Grain DryerAdzimah K. Stephen, Seckley EmmanuelProblem statement: Grains are routinely seen dumped in villages and major cities during the peak of harvest. Therefore it is necessary that these grains are properly dried and stored to ensure availability and wholesomeness throughout the year. Advancements have taken place in the practice of drying since the first world war. Manufacturing methods have greatly improved production rate and the … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,726 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Cadmium (II) Ions Biosorption onto Pretreated Dried Activated SludgeR. Darvishi Cheshmeh Soltani, A. Jonidi Jafari, Gh. Shams KhorramabadiProblem statement: Heavy metals have been one of hazardous components in industrial effluents that can be damaged on the environment by discharging uncontrolled wastewater. The aims of this investigation were biosorption of Cd (II) ions onto pretreated dried activated sludge and determination of kinetic and isotherm of biosorption. Approach: Activated sludge was obtained from Tehran municipal wastewater treatment plant. Activated … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,713 accessesView PDFCite
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.
