Research ArticleOpen accessIn the abstractInvestigating the Effect of Heat on Reinforced Concrete Frame Using Finite Element SoftwareReza Salehi, Abbas Akbarpour Nikghalb RashtiThe present paper examines the effect of heat on the reinforced concrete frame. A concrete frame with a specific geometric dimension has been modeled in ABAQUS finite element software and its loading capacity and other specifications, such as hardness and ductility, have been obtained. Then the concrete frame was heated under temperature 200, 400, 600, 800 and 1000°C and load … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 4 May 2018 · 8,325 accessesView PDFCite
Research ArticleOpen accessIn the abstractTrend Analysis of Some Indices of Extreme Rainfall EventsOlumuyiwa Idowu Ojo, Femi Dakaye, Masengo Francois IlungaClimate change events results in increased temperature, changing rainfall patterns, floods and droughts. These will not only affect human but also affect how environment responds to the events. In this study, analyses of the trend change of 10 indices of Extreme Rainfall Events were carried in three stations of middle belt of Nigeria namely Jos, Lokoja and Makurdi using the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 1 Jan 2018 · 7,865 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatus of Air Quality with Potential Linkage to the Metrological Conditions in Three Major Cities of PakistanNaima Hamid, Muhammad Junaid, Syeda Maria Ali et al.Environmental pollution being fatal for all living organisms is growing adversely due to excessive industrialization and urbanization. Vehicular emissions have aggravated the situation and pose detrimental effects on human health. In this study, the trend of ambient air quality was analyzed in the three metropolitan cities of Pakistan, including Karachi, Lahore and Islamabad for a period of three years (2008-2010). … …American Journal of Environmental Sciences, Vol. 15, Issue 2 · 11 Mar 2019 · 8,854 accessesView PDFCite
Research ArticleOpen accessIn the abstractKMnO4 Modified Carbon Prepared from Waste of Pineapple Leaf Fiber Production Processing for Removal of Ferric Ion from Aqueous SolutionSumrit Mopoung, Thaksaphon BuntermKMnO4 modified carbon materials from waste of pineapple leaf fiber production processing were prepared and characterized. The effects of % weight of KMnO4 (0-5 %wt) and carbonization temperature (500-700°C) were studied by SEM-EDS, XRD, FTIR and BET. The KMnO4 modified waste carbon was used for Fe3+ removal from aqueous solutions. The effects of KMnO4 modification, contact time, pH and loading … …American Journal of Applied Sciences, Vol. 13, Issue 6 · 25 Jun 2016 · 7,687 accessesView PDFCite
Research ArticleOpen accessIn the abstractAPPLYING SEASONAL CLIMATE TRENDS TO AGRICULTURAL PRODUCTION IN TANJUNG KARANG, MALAYSIAMohd Ekhwan Toriman, Lee Qiao Yun, Mohd Khairul Amri Kamarudin et al.The North West Selangor Integrated Agriculture Development Agency (NWS-IADA) is the most productive agricultural part in Selangor, Malaysia. This is partly because of the inherent high fertility of the soils and the moderate variable climate. However, with increasing global concern about climate impacts, this article examines relative importance of climate influences on the paddy production rate over 28 years (1980-2008). … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 6 Jan 2014 · 7,912 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemediation of Diesel Contaminated Soils Using Surfactants: Coulumn StudyE. Salehian, A. Khodadadi, B. HosseiniThis study presents the experimental remediation studies of diesel contaminated soil with Sodium Deducible Sulfate (SDS) as surfactants using column tests. Sandy selected soil had the grain size distribution of # 40 meshes to the # 200 mesh range. The soil columns were contaminated with adequate diesel amount to achieve the concentration of 10000 and 20000 ppm in soil. 0.1, … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 18 Jun 2012 · 8,320 accessesView PDFCite
Research ArticleOpen accessIn the abstractEarly Age Thermal Conditioning Improves Broiler Chick's Response to Acute Heat Stress at Marketing AgeAhmed M. Hassan, P. Gopal ReddyProblem statement: Acute heat stress at marketing age especially in broiler chickens raised in open houses with reduced means of heat exchange leads to economic losses. The objective of this study was to determine beneficial effects of early age thermal conditioning in reducing adverse effects of acute heat stress and decrease losses. Approach: Ninety one day-old broiler chicks were randomly … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 1 · 17 Feb 2012 · 8,660 accessesView PDFCite
Research ArticleOpen accessIn the abstractTime Series Analysis of Rainfall and Temperature Interactions in Coastal CatchmentsGurudeo Anand Tularam, Mahbub IlaheeProblem statement: As a result of climate change more work is now being done on climate indices such as SOI, rainfall, temperature and so on. The research concerning rainfall and temperature variations in coastal tropical and subtropical catchments as noted by the dated references in this study shows a lack of attention. The authors examined long term data from coastal … …Journal of Mathematics and Statistics, Vol. 6, Issue 3 · 30 Sep 2010 · 15,823 accessesView PDFCite
Research ArticleOpen accessIn the abstractDoes Predator Go for Size Selection or Preferential Toxic-Nontoxic Species Under Limited Resource?Joydeep Pal, S. Bhattacharya, J. ChattopadhyayProblem statement: Selectivity is common in predator-prey interaction but the selection mechanism is still unexplored and a debatable issue in modern theoretical and experimental ecology for numerous species across the globe. In present investigation we emphasized the hypothesis that the zooplankton is less inclined to opt the food based on size selectivity criteria than the preferential selectivity for the safe … …OnLine Journal of Biological Sciences, Vol. 10, Issue 1 · 30 Jun 2010 · 7,903 accessesView PDFCite
