Research ArticleOpen accessIn the keywordsMathematical 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 · 7,116 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Correlations Between Mercury Speciation and Dissolved Organic Matter in the Sediment of the Red SeaM. A. Wedyan, F. A. Ababneh, S. Al-RousanThis study addresses the correlations between Hg and organic matter in recent sediment; samples were collected from the Gulf of Aqaba, Red Sea coasts (oligotrophic regions) during 2010. In the present study TOC analyzer was used to determine Total Organic Carbon (TOC) and Total Nitrogen (TN) concentrations and the total amount of mercury (HgT) in sediment samples were analyzed by … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 21 Jun 2012 · 6,799 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBiodegradation of Phenolic Compounds in Creosote Treated Wood Waste by a Composting Microbial Culture Augmented with the Fungus Thermoascus aurantiacusAbdel E. Ghaly, Bopeng Zhang, Deepika DaveProblem statement: Creosote is used as a wood preservative and water proof agent in railway sleepers, utility poles, buildings foundations and fences and garden furniture. It is a mixture of over 300 hydrocarbons which include 75% polycyclic aromatic hydrocarbons, 2-17% phenolic compounds and 10-18% heterocyclic organic compounds. Exposure to creosote may result in several health problems including damage to kidney, … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 2 · 26 Aug 2011 · 9,453 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnticancer Activities of Some New Synthesized Thiazolo[3,2-a]Pyrido[4,3-d]Pyrimidine DerivativesAshraf M. Mohamed, Abdel-Galil E. Amr, Musaed A. Alsharari et al.Problem statement: This study describes the synthesis and anticancer activities of a new series of thiazolo[3,2-a]pyrimidines derivatives (2-7) using 3,5-bisarylmethylene-1-methyl-4- piperidone and 4-aryl-8-arylmethelene-6-methylpyrido[4,3-d]pyrimidine-2(1H)thiones as a starting materials. Approach: The antitumor activities of the newly synthesized compounds 4-7 were evaluated utilizing 60 different human tumor cell lines, representing leukemia, melanoma, lung, colon, brain, ovary, breast and prostate as well as kidney. … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 2 · 23 Aug 2011 · 10,093 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Effect of Rumen Acid Load on Postpartum Performance and Blood Metabolic Responses in Transition Holstein CowsSadjad Danesh Mesgaran, Alireza Vakili, Alireza Heravi Moosavi, Ghasem KoolabadiProblem statement: The transition period is the most stressful time in the production cycle of a dairy cow because of depressed feed intake, endocrine and metabolic changes at parturition. The aim was to determine the effect of rumen acid load on postpartum performance and metabolic parameters in transition Holstein cows. Approach: The Acidogenicity Values (AV) of the diets were determined … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 1 · 25 May 2011 · 7,444 accessesView PDFCite
Research ArticleOpen accessIn the keywordsComparison of Selected Chemical Properties of Peat Swamp Soil Before and After Timber HarvestingMuhamad Ismawi Salimin, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Peat swamp is an important component of the world’s wetlands. Once they are disturbed the tendency for the soil degradation is very high. This study compared selected chemical properties of a peat swamp soil before and after timber harvesting. Approach: Peat soil samples were taken at 0-15 cm depth in 6 plots with 0.1 ha each plot at … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 8,792 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImpact of Emissions from Power Stations on the Ambient Air Quality of Selected Urban Areas in KuwaitBader N. Al-Azmi, V. Nassehi, A.R. KhanIn Kuwait, two main power stations, one comprising of seven-300MW steam generators at Doha and other with eight-300MW steam generators at Subyia cover the major power requirement of Kuwait city.

Research ArticleOpen accessIn the keywordsRedox Sensing and Cardiac Myocyte Loss: Some Recent InsightsShyamal K. GoswamiGeneration of reactive oxygen-nitrogen species (ROS/RNS) has long been ascribed to pathophysiological conditions like ageing, neurodegenerative and cardiovascular disorders. However, more recent evidences suggest that while generation of ROS/RNS at a higher threshold is deleterious, at a lower dose these can act as second messengers, influencing specific cellular events like cell growth and differentiation, embryonic development, protection against ischemic injuries … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 4 · 31 Dec 2007 · 6,350 accessesView PDFCite
