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 abstractComparison of Tuberculin Skin Test and Interferon Gamma Assay for the Diagnosis Latent TuberculosisAbolfazl Poorhasan, Mehdi Haghdoost, Omid MashrabiProblem statement: After HIV infection, TB is the most common cause of mortality due to a single infectious agent. Until 1985, tuberculosis cases in the world were decreasing every year, but then with the prevalence of HIV infection, TB cases are increasing every year. Obviously, with this prevalence of tuberculosis, the best way to control it is to track the … …American Journal of Infectious Diseases, Vol. 6, Issue 2 · 30 Jun 2010 · 7,305 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe First Report of the Occurrence of Anthracnose Disease Caused by Colletotrichum gloeosporioides (Penz.) Penz. & Sacc. on Dragon Fruit (Hylocereus spp.) in Peninsular MalaysiaMasanto Masyahit, Kamaruzaman Sijam, Yahya Awang, Mohd Ghazali Mohd SatarProblem statement: The increasing of dragon fruit (Hylocereus spp.) plantations in Malaysia enhances the researches on this crop, particularly focusing on its physico-chemical characteristics, great potential health benefits and nutritional value. However, its scientific report of disease is still lacking, primarily on anthracnose disease. This study was then conducted to investigate the distribution of anthracnose disease on dragon fruit and … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 11,824 accessesView PDF Cite

Research ArticleOpen accessIn the abstractModeling of Oxygen Transfer Correlations for Stirred Tank Bioreactor Agitated with Atypical Helical Ribbon ImpellerMohd Shamzi Mohamed, Rosfarizan Mohamad, Ramakrishnan Nagasundara Ramanan et al.Problem Statement: Mixing filamentous fungi entails delicate balance between promoting high volumetric oxygen transfer coefficient (kLa) while keeping low hydrodynamic stresses in the microenvironment of cultures. This study examined the oxygen transfer capability of a prototype low shear helical impeller as a potential replacement for the standard Rushton turbine. Approach: The dependence of kLa upon specific power uptake, superficial gas … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 9,167 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEngineering Properties and Compressibility Behavior of Tropical Peat SoilYouventharan Duraisamy, Bujang B.K. Huat, Azlan A. AzizThis paper presents the engineering properties and compressibility behavior of various types of tropical peat soil collected from several locations in Malaysia. These soils represented fibric, hemic and sapric type of tropical peat with organic content ranging from 70% to 90%. The correlations of the various basic engineering properties of the tropical peat soils have been found to be close … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 8,570 accessesView PDF Cite
