AbdullahProblem statement: Daily retrieved Ozone (O3) column data for 12 day for periods varying (11-18 August) 2005 and 2003 and (12-19 February) 2005, obtained from the Atmospheric Infrared Sounder AIRS, are utilized to investigate the ozone distribution over the Southeast Asia. Approach: AIRS included on the Earth Observing System (EOS) Aqua satellite launched on 4 May 2002. Ozone (O3) is … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,978 accessesView PDF Cite

Research ArticleOpen accessIn the abstractToxicological Response of the Green Alga Chlorella vulgaris, to Some Heavy MetalsE. Afkar, H. Ababna, A. A. FathiProblems statement: The disturbance of aquatic ecosystems provoked by heavy metals pollution from industrial and domestic sources, has as consequence the loss of biological diversity, as well as increased bioaccumulation and magnification of toxicants in the food chain. The aim of this study was to evaluate the effect of some heavy metals on some physiological activities of Chlorella vulgaris beyerinck … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 10,787 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStudy on the Thermal Accumulation and Distribution Inside a Parked Car CabinHussain H. Al-Kayiem, M. Firdaus Bin M. Sidik, Yuganthira R.A.L MunusammyProblem statement: When a vehicle is parked under the direct sun, the accumulated heat is affecting many interiors inside the vehicle cabin, such as the vinyl materials of the dashboard, the leather covers and the electronic components. Also, it represents an uncomfortable operating period for the passengers. The studies under this topic are entitled by the vehicle manufacturers as "Vehicle … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 15,521 accessesView PDF Cite

Research ArticleOpen accessIn the abstractKnowledge Representation of Ion-Sensitive Field-Effect Transistor Voltage Response for Potassium Ion Concentration Detection in Mixed Potassium/Ammonium Ion SolutionsWan Fazlida Hanim Abdullah, Mohd Alaudin Mohd Ali, Md Shabiul Islam, Masuri OthmanProblem statement: The Ion-Sensitive Field-Effect Transistor (ISFET) is a metal-oxide field-effect transistor-based sensor that reacts to ionic activity at the electrolye/membrane/gate interface. The ionic sensor faces issue of selectivity from interfering ions that contribute to the sensor electrical response in mixed solutions. Approach: We present the training data collection of ISFET voltage response for the purpose of post-processing stage neural … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,820 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluation of Leaf Total Nitrogen Content for Nitrogen Management in a Malaysian Paddy Field by Using Soil Plant Analysis Development Chlorophyll MeterA. Gholizadeh, M. S. M. Amin, A. R. Anuar, W. AimrunProblem statement: Laboratory plant testing is usually time-consuming and high-costing. Hence, plant nutrient variability must be measured rapidly and the information made known to the farmers before the new season starts. Site-specific crop management, well-established in some developed countries, is now being considered in other places such as Malaysia. Approach: The application of site-specific management principles and techniques to diverse … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 9,240 accessesView PDF Cite

Research ArticleOpen accessIn the abstractValidation of the Calculation and Measurement Techniques of Earth Resistance ValuesN. Mohamad Nor, R. Rajab, K. RamarMuch research has been published in the literature on the mathematical approaches to obtain the most accurate earth resistance and resistivity values. However, the published research only conducted the comparisons among the mathematical/computational techniques and so far none has conducted validation tests of these mathematical/computational methods against the real earth resistance measurement at real field sites. Thus, the main contribution … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,220 accessesView PDF Cite
