Research ArticleOpen accessIn the abstractInfluence of Supplementary Bioavailable Carbon on the Thermal and Biological Kinetic Parameters of the Composting Process of Tomato Plant TrimmingsA.E. Ghaly, F. AlkoaikThree laboratory-scale bioreactors were used to investigate the influence of bioavailable carbon addition on the composting process of tomato remains. Sugar, cheese whey and used cooking oil were used as bioavailable carbon sources. The amounts of materials added to the compost mixture had equal energy contents. The initial moisture contents and C: N ratios of the compost mixtures were maintained … …American Journal of Environmental Sciences, Vol. 2, Issue 1 · 31 Mar 2006 · 6,563 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Purification of Bacterial Strains from Treatment Plants for Effective and Efficient Bioconversion of Domestic Wastewater SludgeK. C.A. Jalal, Md. Z. Alam, Suleyman A. Muyibi, P. JamalForty six bacterial strains were isolated from nine different sources in four treatment plants namely Indah Water Konsortium (IWK) sewage treatment plant, International Islamic University Malaysia (IIUM) treatment plant-1,-2 and -3 to evaluate the bioconversion process in terms of efficient biodegradation and bioseparation. The bacterial strains isolated were found to be 52.2% (24 isolates) and 47.8% (22 isolates) in the … …American Journal of Environmental Sciences, Vol. 2, Issue 1 · 31 Mar 2006 · 7,575 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparison of Spatio-Temporal Bayesian Models for Reconstruction of Rainfall Fields in a Cloud Seeding ExperimentSujit k. sahu, Giovanna Jona Lasinio, Arianna orasi, Kanti V. MardiaIn response to the drought experienced in Southern Italy a rain seeding project has been setup and developed during the years 1989-1994. The initiative was taken with the purpose of applying existing methods of rain enhancement technology to regions of south Italy including Puglia. The aim of this study is to provide statistical support for the evaluation of the experimental … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,810 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermodynamic Investigation of Two-Stage Absorption Refrigeration System Connected by a CompressorL. Kairouani, E. Nehdi, R. B. IffaThe present work is to analyze a two-stage cycle based on the ammonia-water absorption system, with intermediate compression. The two generators of the system are heated by geothermal energy at low temperature. The study shows that this system makes it possible at lower generator temperature, under the limits permitted by the systems suggested up to now. For Tg = 335 … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractMacroeconomic Impact of Trade on Namibian Growth: An Empirical IllustrationCyril A. OgbokorThe study analyses the role of trade on the economy of Namibia by considering a different specification of the traditional export-growth model. Foreign direct investment is included to capture the potential effect of this variable on growth. Utilising a combination of bivariate and multivariate models, the researcher estimated the relationship between the selected macroeconomic variables used for the study. Macroeconomic … …Journal of Social Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,864 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmission of Nitrogen Dioxide from Butane Gas Heaters and Stoves IndoorsMarwan Ghosn, Roula Flouty, Najat A. SalibaLevels of indoor nitrogen dioxide (NO2) in a home equipped with butane gas stove and heaters are reported between the months of February and July 2003. Diffusion passive sampling was used for the simultaneous measurements of indoor and outdoor NO2 concentrations. The overall average indoor NO2 concentrations were 15.6 and 22.3 μg m-3 for the living room and kitchen, respectively, … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 9,471 accessesView PDFCite
Research ArticleOpen accessIn the abstractWind Speed Simulation Using WaveletsA. H. Siddiqi, S. Khan, S. RehmanMost of the renewable energy sources have direct or indirect link with the sun. Wind is also a form of solar energy. It is initiated by uneven heating of the atmospheric air by the sun, affected from the topography and surface roughness of the earth's surface and rotation of the earth. The earth's terrain, water surfaces and vegetation cover modifies … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,546 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Mechanism of Stock Market Integration: Evidence for the Taiwan and U.S. Stock MarketMin-Hsien Chiang, Rung-Ho Lai, Hsiao-Ching LeeThis study investigates the sources of the comovement of the Taiwan and U.S. stock market. The empirical evidence shows that both economic fundamentals and equity risk premiums can act as transmission mechanisms of both markets. In the meantime, the financial integration is much stronger than real economic integration. Moreover, the deregulation of foreign investments in Taiwan and the Southeast Asian … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 7,195 accessesView PDFCite
