Research ArticleOpen accessIn the keywordsRAM 1.0 Software for Gaussian-Plume Multiple Source Air Quality SimulationLiren Yu, Paulo I.F. de AlmeidaThis study presents a developed software in environmental engineering, namely RAM 1.0 (RAM: Regulatory Air Model), adopted completely Graphical User Interface (GUI) technique, for operating in various Windows-based microcomputers. RAM 1.0 software consists of the improved RAM Model and RAM Algorithm as well as developed RAM 1.0 Graphical User Interface, respectively. RAM Model takes into account different ambient characteristics, meteorological … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,458 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAir Quality Interpretation of Four Geographically Distinct Hot Spot States of India-An Appraisal Using Aerosol Optical Depth and Particulate MatterJacob Joshua, Aishwarya Sathyachandran, Chenicherry House SujathaThe application of Moderate Resolution Imaging Spectroradiometer-Aerosol Optical Depth (MODIS-AOD) for Air Quality (AQ) assessment has contributed significantly by making use of a spatiotemporal relationship between ground-level particulate matter and aerosol optical density at both city and state levels. Traditional ground-based site-specific particulate matter monitoring method has found a profound gap in their spatial coverage. Such challenging situations prevail over … …American Journal of Environmental Sciences, Vol. 18, Issue 6 · 8 Feb 2023 · 5,883 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPersonal Exposure to PM2.5 in the Various Microenvironments as a Traveler in the Southeast Asian CountriesSemih Ozler, Karoline K. Johnson, Michael H. Bergin, James Jay SchauerAir pollution has become a pressing issue in today’s society because of its significant effects on humans, animals, plants, air quality, climate and the wider environment. Most urban areas are associated with one or more air pollutants which are emitted from local or regional pollution sources including vehicle exhausts, fossil fuels using in energy production, emissions from industrial and mining … …American Journal of Environmental Sciences, Vol. 14, Issue 4 · 27 Oct 2018 · 9,274 accessesView PDF Cite

EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,521 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGaussian Dispersion Model to Estimate the Dispersion of Particulate Matters (Pm2.5) and Sulfur Dioxide (SO2) Concentrations on Tribal Land, OklahomaDejene Alemayehu, Francine HackettAir quality in most parts of Kay County is good and unlikely to cause major health problems. However, Kaw Nation wants to know if the concentration of Particulate matters (PM2.5) and Sulfur dioxide (SO2) released from power plants, refinery and carbon black plant in Oklahoma reaches the Tribal land at Kanza Travel Plaza, Braman, Kay Co. Oklahoma. Kanza Travel Plaza … …American Journal of Environmental Sciences, Vol. 11, Issue 6 · 8 Dec 2015 · 7,964 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Noises on Fujisaki’s Model of Fundamental Frequency Contours for Thai DialectsSuphattharachai Chomphan, Chutarat ChompunthProblem statement: Modeling of fundamental frequency (F0) contour plays an important role on the natural speech processing, since F0 is an important speech feature defining the human speech prosody. In Thai, there are four main dialects spoken by Thai people residing in four core region including central, north, northeast and south regions. Environmental noises are also plays an important role … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 25 Aug 2012 · 6,981 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Environmental Noises on Fundamental Frequency Contours of Thai DialectsSuphattharachai Chomphan, Chutarat ChompunthProblem statement: Fundamental Frequency (F0) is an important speech feature defining the human speech prosody. It is the resultant of the vibration of human’s vocal chords in speech production. In Thai, there are four main dialects spoken by Thai people residing in four core region including central, north, northeast and south regions. Environmental noises are also playing an important role … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 9 Mar 2012 · 7,031 accessesView PDF Cite
