Research ArticleOpen accessIn the abstractDevelopment and Testing of an Ammonia Removal Unit from the Exhaust Gas of a Manure Drying SystemA. E. Ghaly, K. N. MacDonaldThe storage and handling of animal wastes is one of the main sources of ammonia gas emissions. Ammonia gas has a distinct, unpleasant odor and can become detrimental to the health of humans and animals at high concentrations. Ammonia emissions are of particular concern in manure drying systems, where large losses of nitrogen, in the form of ammonia can cause … …American Journal of Environmental Sciences, Vol. 9, Issue 1 · 16 Feb 2013 · 7,415 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnumeration of Microbes and Gas Production During Denitrification and Nitrogen Fixation Processes in SoilA. E. Ghaly, K. N. MacDonaldDry plant material contains 2-4% nitrogen, making it an essential nutrient for all plants. The nitrogen cycle regulates the pathways which transform nitrogen from a relatively inert dinitrogen gas to forms of organic nitrogen such as proteins and nucleic acids. Denitrification and nitrogen fixation are the two most important processes that remove and add nitrogen to the soil, respectively. The … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 11 Sep 2012 · 8,618 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Analysis of How the Electrical Training Center Site is Affected by Air PollutionBassam A. Al-HelouThe study has come to the result that the monitoring site at the Electrical Training Centre (ETC) at Al-Hashimyeh town is exposed to grave pollution that goes beyond Jordanian standards of the ambient air. It has, indeed, shown that Sulfur dioxide (SO2) exceeds the limits and its seasonal concentration matches forward with the average wind speed. SO2 concentration reaches its … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 3 Sep 2012 · 7,111 accessesView PDFCite
Research ArticleOpen accessIn the abstractSequential Remediation Processes for Effective Removal of Oil from Contaminated SoilsDeepika Dave, Reema Alharathi, Abdel GhalyProblem statement: Over 2.2 billions of oil and oil products were transported every year and often these activities can result in air, water and soil contamination. Expousure to petroleum products can cause health problems to humn and animals and affect marine animals and wildlife habitats. Approach: The objective of this study was to developed a technology for the remediation of … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 18 Nov 2011 · 8,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Heat or Heat-Xylose Processing on Nitrogen Fractions and in Situ/In Vitro Ruminal and Post-Ruminal Protein Disappearance of Guar MealHossein Jahani-Azizabadi, Mohsen Danesh Mesgaran, Ali Reza Vakili et al.Problem statement: Guar meal is a by-product consisting of hull and germ and is mostly used as a protein source in poultry and ruminant rations. The aim was to determine the effect of heat or heat-xylose processing on nitrogen fractions, in situ ruminal degradation parameters and in situ/in vitro ruminal and post-ruminal disappearance of guar meal. Approach: Samples were intact … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 4 · 27 Dec 2010 · 8,153 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Chemical Properties on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: It is important to investigate the seriousness of degradation of peat swamp forest caused by skidding system in terms of its function as a carbon sink. In this study, we formulated assumptions that conditions of our research site before the introduction of skidding system were in their natural states, thus that changes measured are clearly caused by skidding … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 7,915 accessesView PDFCite
Research ArticleOpen accessIn the abstractForecasting and Time Series Analysis of Air Pollutants in Several Area of MalaysiaMohd Zamri Ibrahim, Roziah Zailan, Marzuki Ismail, Muhd Safiih LolaProblem statement: In keeping abreast with Malaysia’s rapid economic development and to meet the nation's aspiration for an improved quality of life, clean-air legislation limiting industrial and automobile emissions was adopted in 1978. Approach: Yet, to this day, air pollution from both sources still poses a problem for the nation. In order to predict the status of future air quality … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,761 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Morphological, Biochemical and Biological Studies of Halophilic Streptomyces sp. Isolated from Saltpan EnvironmentDeepika T. Lakshmipathy, Krishnan KannabiranProblem statement: Dermatophytes have developed resistance to the existing antifungal antibiotics. As a part of our continuous search we had isolated, identified and characterized actinomycetes from the halophilic environment having antagonistic activity against the dermatophytes namely Trichophyton, Microsporum and Epidermophyton. Approach: Actinomycetes were isolated from the soil sample collected from the Ennore saltpan region, Chennai, India and screened for antidermatophytic … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 7,735 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Precipitation Fluctuation on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: It is important to compare the effect of extremely different rainfall conditions on soil carbon storage of lowland tropical peat swamp forest. Therefore, under these natural rainfall gradient, the objectives of this study were to determine whether rainfall affects soil carbon storage of a tropical peat swamp forest and to determine what correlations between variables occurs which stimulate … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 8,603 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimizing of Trichoderma viride Cultivation in Submerged State FermentationHayyan Ismaeil Al-Taweil, Mohammad Bin Osman, Aidil Abdul Hamid, Wan Mohtar Wan YussofProblems statement: A study in Malaysia had shown a strain of Trichoderma viride was isolated from the soil. Questions were raised whether Trichoderma viride submerged state fermentation affected by parameters and which of them is effective? Approach: To investigate the effects of the submerged state fermentation parameters; concentrations of carbon g L-1; (10, 45 and 80), glucose, nitrogen g L-1; … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 10,076 accessesView PDFCite
