Research ArticleOpen accessAll words, across the recordAnaerobic Transformation of Biodegradable Waste; Simultaneous Production of Energy and FertilizerAmirhossein Malakahmad, Syazana Nasrudin, Noor Ezlin Ahmad Basri, Shahrom Md ZainAlmost 40% of the total waste produced in developing countries is made of biodegradable waste. Typically the waste including the biodegradable portion is transported to the so-called landfills without any segregation process, treatment and utilization in advance. Although mitigation practices such as source reduction, reuse and recycle are essential and required to be practiced in any integrated waste management plan, … …American Journal of Environmental Sciences, Vol. 9, Issue 2 · 10 Mar 2013 · 7,379 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSynthesis and Biological Evaluation of 6-Hydroxy-4-Methyl-5,7-(Bis-p-ChlorophenylAzo) CoumarinDalal M. Ibrahim, Juliana Jumal, Farah Wahida Harun6-hydroxy-4-methyl-5,7-(bis-p-chlorophenylazo)coumarinhas been synthesized and characterizedby CHN elemental analysis, FTIR, 1H-NMR-spectroscopy andmass-spectral data. Cytotoxic screening by MTT assay was carried out on the compoundagainst breast cancer cells. The overall results from preliminary screeningprogram revealed that the cell proliferation was highly inhibited by 6-hydroxy-4-methyl-5,7-(bis-p-chlorophenylazo)coumarin with the value of 2.81%, at concentration of 30 µg mL-1 comparedwith the untreated control cells and also … …American Journal of Applied Sciences, Vol. 13, Issue 1 · 21 Dec 2015 · 7,673 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTermite Damage to Buildings: Nature of Attacks and Preventive Construction MethodsAbdel Ghaly, Skai EdwardsProblem statement: Termites are an essential member of the soil ecosystem and are found throughout the world. In their natural environment, they improve soil pH, organic carbon content, water content and porosity by cycling dead organics. However, they can negatively impact human welfare by causing damage to unprotected timber structures, underground cables, earthen dams, irrigation ditches and farming equipment. Globally, … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 12 Jul 2011 · 26,775 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordInfluence 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 · 6,567 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDesign, Synthesis, Biological Screening and Structure Activity Relationship Study of 4, 6-Dimethyl-2-(Substituted) Mercapto-3-(Substituted) Pyridines as Anti Tubercular AgentsMehul M. Patel, Mahesh T. ChhabriyaProblem statement: Tuberculosis is a leading global mortality factor which has not been effectively controlled, with 1.7 million deaths per year and 8.9 million new cases. Aerobic microbe Mycobacterium tuberculosis H37Rv (MTB) is the causative agent of tuberculosis. Although many active antitubercular agents have since been developed, drug resistance will continue to be a problem. Therefore, there is a clear … …American Journal of Infectious Diseases, Vol. 7, Issue 3 · 3 Nov 2011 · 7,432 accessesView PDFCite
