Research ArticleOpen accessIn the abstractTrends in Maximum Daily Rainfall in Marginal Desert Environment: Signs of Climate ChangeKhaldoun A. Al-Qudah, Abdullah A. SmadiProblem statement: Change in intense precipitation has been used as an indicator for anticipated climate change. The trend in maximum daily rainfall in 10 rainfall stations distributed in the north and north east of Jordan has been investigated. Based on mean annual rainfall and geographic location, rainfall stations were divided into subhumid, semi-arid and arid stations. Approach: The regression approach … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 14 Sep 2011 · 7,401 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Carbon and Selected Macronutrients in Forest-Floor Litter of Rehabilitated and Secondary ForestsMelvin Ku Kin Kin, Japar Sidik Bujang, Osumanu Haruna Ahmed et al.Problem statement: Forest rehabilitation with human assistance by species selection and management shortens the time needed to rehabilitate degraded land as compared to natural succession. Empirical data on litter nutrient contents of tropical rain forests in Southeast Asia have been established, however it is limited to rehabilitated degraded lands. The objective of this study was to determine contents of carbon … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 20 Aug 2011 · 7,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractCognitive-Enhancing and Antioxidant Activities of Quercetin Liposomes in Animal Model of Alzheimer's DiseaseTerdthai Tong-un, Panakaporn Wannanon, Jintanaporn Wattanathorn, Wathita PhachonpaiProblem statement: Recent findings demonstrated the crucial role of oxidative stress on the pathophysiology of Alzheimer’s Disease (AD). Antioxidant intake is beneficial to delay or inhibit the progression of this disease. Quercetin, a bioflavonoid in fruits and vegetables, has a powerful antioxidant activity both in vitro and in vivo. Claims that quercetin has many biological activities. However, quercetin is rapidly … …OnLine Journal of Biological Sciences, Vol. 10, Issue 2 · 31 Oct 2010 · 7,880 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpacts of Typhoon on Wave Height at Bangkhuntien ShorelinePrasertsak Ekphisutsuntorn, Prungchan Wongwises, Jiang Zhu, Suphat VongvisessomjaiProblem statement: In this study, the changing of wave height at Bangkhuntien during a passage of typhoon LINDA was simulated by using the Simulating WAves Nearshore Model (SWAN) version 40.41. The study domain covered from 99-101°E longitude and 12-14°N in latitude with resolution of 2.4×2.4 km. The simulation covered 10 days during typhoon LINDA entering into the Upper Gulf of … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 7,465 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatistical Optimization of Fermentation Conditions for Cellulase Production from Palm Oil Mill EffluentJamal I. Daoud, Md. Zahangir AlamProblem statement: Palm oil mill effluent discharged by the oil palm industries is considered as the mixed of high polluted effluent which is abundant (about 20 million tonnes year-1) and its effect contributes to the serious environmental problems through the pollution of water bodies. Approach: The aim of this study was to identify the potential of low cost substrate such … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 8,192 accessesView PDFCite
Research ArticleOpen accessIn the abstractRelationship between Rice Yield and Apparent Electrical Conductivity of Paddy SoilsM.H. Ezrin, M.S.M. Amin, A.R. Anuar, W. AimrunProblem statement: Understanding the relationships between rice yield and soil properties such as bulk electrical conductivity is of critical importance in precision farming. The apparent Electrical Conductivity of soil (ECa) is influenced by a combination of physico-chemical properties including soluble salts, clay content and mineralogy, soil water content, bulk density, organic matter and soil temperature. Accordingly, ECa is considered as … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 8,545 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Daily and Monthly Results of Three Evapotranspiration Models in Tropical Zone: A Case StudySeyed Reza Saghravani, Sa’ari Mustapha, Shaharin Ibrahim, Elias RandjbaranProblem statement: Evapotranspiration (ET) has crucial role in agricultural activity, water management and hydraulic engineering. Recently many forms of the equation have been applied for estimating daily and monthly evapotranspiration around the world. Approach: In this study, the daily and monthly ET was estimated by Penman, Penman-Monteith (P&M) and Hargreaves equation to evaluate general relationships for estimating monthly and daily … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 7,645 accessesView PDFCite
