Research ArticleOpen accessIn the abstractA Philosophical Analysis of the Challenges of Science and Technology in Contemporary Africa: The Nigerian ExperimentAkinnawonu Benson MonehinScience and technology engendered unexpected social, political and health related problems. These included corrupt and dubious utilization of information and communication technology, environmental pollution and protection and depletion of the ozone layer which endangered human health. This sstudy examined the positive and negative implications of science and technology in Africa using Nigeria as a case study. This attempt became germane … …Journal of Social Sciences, Vol. 4, Issue 2 · 30 Jun 2008 · 8,269 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvidence of Oxidative Stress in Autism Derived from Animal ModelsXue Ming, Michelle A. Cheh, Carrie L. Yochum et al.Autism is a pervasive neurodevelopmental disorder that leads to deficits in social interaction, communication and restricted, repetitive motor movements. Autism is a highly heritable disorder, however, there is mounting evidence to suggest that toxicant-induced oxidative stress may play a role. The focus of this article will be to review our animal model of autism and discuss our evidence that oxidative … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 7,121 accessesView PDFCite
Research ArticleOpen accessIn the abstractWater Quality Assessment of A Constructed Wetland Treating Landfill Leachate and Industrial Park RunoffC. Galbrand, I. G. Lemieux, A. E. Ghaly et al.A surface flow constructed wetland was used for the treatment of landfill leachate and industrial park runoff. The wetland consisted of seven cells and was designed as a kidney shape to facilitate high retention time. The water quality was assessed for iron, manganese, phosphorus (orthophosphate), pH, dissolved oxygen (DO), nitrogen (ammonia, nitrate, nitrite and TKN), chemical oxygen demand (COD), total … …American Journal of Environmental Sciences, Vol. 4, Issue 2 · 30 Apr 2008 · 7,376 accessesView PDFCite
Research ArticleOpen accessIn the abstractThree Mild Stresses Known to Increase Longevity in Drosophila melanogaster Flies do not Increase Resistance to Oxidative StressÉric Le BourgExposure to a mild stress at a young age (hypergravity, cold or heat) increases longevity and resistance to heat shocks in Drosophila melanogaster flies and it may also delay behavioral aging and increase resistance to other stresses. The effect of these mild stresses on resistance to oxidative stress has not been studied. Flies were thus fed on a saccharose solution … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,304 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Preliminary Investigation into the Environmental Awareness of the Omani Public and their Willingness to Protect the EnvironmentSabah A. Abdul-WahabThis study was conducted with the objective of evaluating the present status of environmental awareness of Omani citizens and their willingness to contribute to environmental protection. The focus of the study was to investigate the Omani public’s level of knowledge about general basic and current local and international environmental issues and to find out their environmental attitudes and behaviors towards … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 7,153 accessesView PDFCite
Research ArticleOpen accessIn the abstractRedox 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
Research ArticleOpen accessIn the abstractHIV/AIDS Prevention Knowledge among Youth in Cape Town, South AfricaKermyt G. Anderson, Ann M. BeutelHIV/AIDS knowledge is an important component of HIV/AIDS risk prevention strategies that may influence engagement in high risk behavior. This paper examines HIV/AIDS prevention knowledge among a representative sample of 4,174 youth living in Cape Town, South Africa. Data come from the Cape Area Panel Study (CAPS), and include black, coloured, and white respondents ages 14-22. Using an open-ended question, … …Journal of Social Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 9,224 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Case Study of River Rehabilitation for Fish in Northern Italy: The Panaro River ProjectClaudio Comoglio, Enrico Pini Prato, Mauro Ferri, Massimiliano GianaroliThe restoration of longitudinal connectivity of a watercourse altered by man-made obstacles is a key issue for the protection and safeguard of freshwater ecosystems and the construction of fish passes constitutes a relevant ad hoc measure. However, in many countries, like Italy, there is still not an adequate technical-scientific background and experience in this field and therefore several migratory species … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,031 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Canadian Regulations and Remediation Methods for Diesel Oil Contaminated SoilsD. G. Rushton, A E. Ghaly, K. MartinellDiesel fuel released into the environment can contaminate ground water, degrade potable water supplies and cause the collapse of fisheries. They are toxic to both animals and humans and can affect the liver, lungs, kidneys, and nervous system leading to cancer as well as immunological and reproductive effects. The objectives of this study were to review current Canadian regulations pertaining … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 8,764 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Study by Electrochemical Impedance Spectroscopy (EIS) On The Corrosion Resistance of Industrial and Laboratory Zinc CoatingsY. Hamlaoui, F. Pedraza, L. TifoutiIn this work, corrosion monitoring of Zn-based coatings is investigated through potentiodynamic and electrochemical impedance spectroscopy (EIS) methods. The first part of the study is devoted to galvanised coatings conventionally manufactured in the industry. The second part focuses on the corrosion resistance of a laboratory-made electrolytic coating. For such purpose, the corrosion behaviour is studied in NaCl media under various … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,602 accessesView PDFCite
