Research ArticleOpen accessIn the abstractIndoor Air Quality and Prevalence of Sick Building Syndrome Among Office Workers in Two Different Offices in SelangorMohd Ezman Zamani, Juliana Jalaludin, Nafiz ShaharomThis study was done to investigate the relationship between Indoor Air Quality (IAQ) and prevalence of Sick Building Syndrome (SBS) in two different offices (old and new) in Selangor. Hundred and seventy workers were selected consist of 85 office workers for each building. Questionnaire based on Indoor Air Quality and Work Symptoms Survey, NIOSH, Indoor Environmental Quality Survey, 1991 was … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 10 Oct 2013 · 9,468 accessesView PDFCite
Research ArticleOpen accessIn the abstractEVIDENCE OF THE ENVIRONMENTAL KUZNETS CURVE: IMPLICATIONS OF INDUSTRIAL TRADE DATAJamalludin Sulaiman, Azlinda Azman, Behnaz SabooriThis study examines the dynamic relationship between CO2 emissions and economic growth in Malaysia for the period of 1980-2004. The evidence of the Environmental Kuznets Curve (EKC) is tested by including energy consumption, dirty export from Malaysia to China and dirty import from China to Malaysia based on the two and three-digit ISIC data which reflect pollution-intensive manufacturing. Using dirty … …American Journal of Environmental Sciences, Vol. 9, Issue 2 · 26 Mar 2013 · 7,254 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Potentialof Renewable Energy: Using The Environmental Kuznets Curve ModelJamalludin Sulaiman, Azlinda Azman, Behnaz SabooriThis study examines the potential of Renewable Energy Sources (RES) in reducing the impact of carbon emission in Malaysia and the Greenhouse Gas (GHG) emissions, which leads to global warming. Using the Environmental Kuznets Curve (EKC) hypothesis, this study analyses the impact of electricity generated using RES on the environment and trade openness for the period 1980-2009. Using the Autoregressive … …American Journal of Environmental Sciences, Vol. 9, Issue 2 · 13 Mar 2013 · 14,783 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of pH and Cellular Response in Pulmonary Fibroblasts After Exposure to Market Street World Trade Center Particulate MatterMichelle Hernandez, Sung Choi, Ann Marie DiLorenzoChronic health conditions have been noted among first responders and residents exposed to the dust generated from the World Trade Center (WTC) collapse on September 11, 2001. This study sought to isolate a single factor thought to play a substantial role in the decreased lung function of World Trade Center (WTC) workers and victims. Human pulmonary fibroblasts were exposed to … …OnLine Journal of Biological Sciences, Vol. 12, Issue 4 · 8 Feb 2013 · 7,327 accessesView PDFCite
Research ArticleOpen accessIn the abstractGaseous Emissions and Combustion Efficiency Analysis of Hydrogen-Diesel Dual Fuel Engine under Fuel-Lean ConditionPrateep Chaisermtawan, Sompop Jarungthammachote, Sathaporn Chuepeng, Thanya KiatiwatExhaust gas emissions from diesel engine combustion using alternative fuel may change in their quantities that can affect exhaust gas after-treatment devices and environmental ambient. This study presents theoretical analysis of combustion generated emissions and efficiency of hydrogen-diesel duel fuel in fuel-lean condition. A chemical equilibrium method by minimizing Gibbs free energy is employed to estimate exhaust gas products from … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 1 Sep 2012 · 7,514 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Ambient and Indoor Air Quality in the Building Built on the Former LandfillAnuar Ithnin, Nazipah Zakaria, Nor Azura Sulong et al.Problem statement: The air quality study of PPR Taman Wahyu II, Selayang, Selangor was a residential project that was built on the former landfill site. The landfill site will produce landfill gases which can influence the air quality level in and outside the building. Approach: This air quality study also involving PPR Intan Baiduri, Batu Caves, Selangor as a control … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 21 Jun 2012 · 6,994 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Dry Ice Application in Fish Hold of Fishing Boat on the Fish Quality and Fisherman IncomeSemin, Alam Baheramsyah, Amiadji, Abdul Rahim IsmailProblem statement: This study presents the effect of dry ice application in the fish hold of fishing boat on the fish quality and fisherman income. Dry ice is made with compressed CO2 gas to produce hot, high-pressure gas. Hot gas then cooled to condense into liquid CO2, which is still high pressure. Dry ice can be used to cool a … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 11 Oct 2011 · 8,106 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrobial Activities as Affected by Peat Dryness and AmeliorantEdi Husen, Fahmuddin AgusProblem statement: Acceleration of microbial activities and thus of CO2 emission in drained peat soils used for agriculture, is of the main environmental concern. The objectives of this study were to (i) examine microbial activities in peat samples treated with different levels of water contents and ameliorants and (ii) evaluate the relative contribution of microbial groups to peat respiration. Approach: … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 29 Sep 2011 · 7,548 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing Forest Plantation Productivity of Exotic and Indigenous Species on Degraded Secondary ForestsYetti Heryati, Arifin Abdu, Mohd Noor Mahat et al.Problem Statement: There is general agreement that human activities such as deforestation and land use change to other land use types have contributed to degraded secondary forests or forestland and increases the emission of greenhouse gases which ultimately led to global climate change. An establishment of forest plantation in particular is regarded as an important approach for sequestering carbon. However, … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 10,520 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis of Zeolite A from By-Product of Aluminum Etching Process: Effects of Reaction Temperature and Reaction Time on Pore VolumeKanokorn Hussar, Sombat Teekasap, Nisakorn SomsukProblem statement: Increasing of the carbon dioxide (CO2) concentration in the atmosphere creates a global warming. Zeolite is used as CO2 absorbent. Approach: By-products from aluminum etching process, which carry a large amount of Al2O3 content, are useable as raw materials for synthesis zeolites type A using hydrogel process. A pore volume of zeolites is the key to achieve high … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 7,840 accessesView PDFCite
