Research ArticleOpen accessIn the abstractThermal Energy Storage in the Ground of a Greenhouse by the Polypropylene Capillary Heat ExchangerM. Lazâar, S. Koôli, M. Hazami et al.The problem of temperature inversion is one of solar origin principal problems about which the cultures under shelters complain. Indeed, for the winter period, the temperature under greenhouse is very low at night and it is rather high during the day in summer. Consequently, the heating of the greenhouses is essential. In this work, we studied the advisability of using … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,944 accessesView PDFCite

Research ArticleOpen accessIn the abstractPredictors of Technology Deployment Among Malaysian TeachersNaresh Kumar, Raduan Che Rose, Jeffrey Lawrence D’SilvaTechnologies advocate researchers had identified a number of factors that affect individual teachers' usage of computers. Nevertheless mix results were reported in literature. Hence, this study used personal characteristics and the technology acceptance constructs to understand the Actual Usage of Computer (AUC) among Malaysian teachers. The final model derived from this study was able to explain and predict approximately 54.5% … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,036 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review on Some Organic Acids Additives as Shelf Life Extenders of Fresh Beef CutsMohamed B. Jamilah, K.A. Abbas, R. Abdul RahmanThis study was aiming to present some approaches by which the shelf life of fresh beef cuts was extended. These approaches were based on using organic acids. Therefore the work was started with highlighting the deterioration of some quality attributes due to spoilage and pathogenic microorganisms. These attributes included colour, flavour and lipid oxidation changes. In a given holding temperature, … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 8,739 accessesView PDFCite
