Research ArticleOpen accessIn the abstractMeasurement of Ground Level Ozone at Different LocationsYasmen A. Mustafa, Sinan J. MohammedProblem statement: Ground level ozone is the most important index substance of photochemical smog. Photochemical smog is now observed in many urban and industrial centers around the world and it has become a common phenomenon in many large cities. Ozone is a most harmful pollutant for humans, in addition it plays an important role in damaging vegetation and materials. Therefore … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 13 Jun 2012 · 7,402 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnnual Concentration Report and Emission Sources Analysis of the Air Pollutants Measured by the Air Quality Monitoring StationP Khaenamkaew, S. Raksawong, K. Wongsorntam et al.Problem statement: Air Quality Monitoring (AQM) station at Kasetsart University, Si Racha Campus, Thailand, was routinely monitor the annual concentrations and analysis the emission sources of the air pollutants in the area since 2007. The level of concentration CO, SO2, NOx and O3 were measured. PM10 concentration was measured by mean of TOEM method. The PM10 and TSP (manifold) filters … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 1 Oct 2011 · 6,733 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSugarcane Response to Water-Deficit Stress during Early Growth on Organic and Sand SoilsDuli Zhao, Barry Glaz, Jack C. ComstockProblem statement: Approximately 20% of sugarcane (Saccharum spp.) is grown on sand soils in south Florida, USA. Sugarcane yields in the region linearly increased in last 33 years on organic (muck) soils, but not on sand soils. Water deficit during the formative growth phase on sand soils probably limits sugarcane yields. Approach: A greenhouse study was conducted in 2009 and … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 10,260 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Different Sanitizers on Microbial, Sensory and Nutritional Quality of Fresh-Cut Jalapeno PeppersSaul Ruiz-Cruz, Emilio Alvarez-Parrilla, Laura A. de la Rosa et al.Problem statement: Sanitation is a critical step to insure safety of fresh-cut produce. The inadequacies of chlorine, currently used as a sanitizer, have stimulated interest in finding safer, more effective sanitizers, however little is known on the impact of these novel sanitizers on sensory and nutrimental quality of the treated products. Approach: The effect of four sanitizers: Sodium hypochlorite (OCl), … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 9,124 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPhysiological Response of Soybean (Glycine max) to Foliar Application of Methanol Under Different Soil MoisturesFarzad Paknejad, Mojtaba Mirakhori, Majid Jami Al-Ahmadi et al.Problem statement: Many cultivated area are situated in arid zone, where crop photosynthesis and productivity has limited by drought. Thus any treatment, such as methanol, that improve plant water relation and reduce stress impacts, could be benefit. Approach: In order to investigate effects of methanol application on some physiological properties of soybean under low water stress, a factorial experiment was … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,150 accessesView PDF Cite
