Research ArticleOpen accessIn the abstractIDENTIFICATION, MOLECULAR CHARACTERIZATION AND EVALUATION OF SOME RUMINAL BACTERIA THAT CATALYZE AND DEGRADE PLANT CELLULOSIC MATERIALSAhmed A. Mansour, T. S. El-Tayeb, N. E. El-BordenyIn the last few years there was a growing economic awareness about plant wastes and use it in compost production or in feeding of farm animals, some of these wastes are useless and cause a lot of problems in Egyptian environment. This study was designed to isolate, identify and evaluate some ruminal bacterial isolates to facilitate the in vitro degradation … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 10 Dec 2013 · 7,134 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing Soil Fertility Status of Rehabilitated Degraded Tropical RainforestAiza Shaliha Jamaluddin, Arifin Abdu, Hazandy Abdul-Hamid et al.An assessment of forest rehabilitation program in relation to soil fertility status by using soil indices could provide fundamental information on soil suitability for species preferences and improve the effective technique for future rehabilitation program in tropical rainforests. This study was conducted in order to characterize the soil properties and identifying the soil fertility status of rehabilitated and secondary forests. … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 19 Jul 2013 · 8,457 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcoustic Properties of Innovative Material from Date Palm FibreLamyaa Abd AL-Rahman, Raja Ishak Raja, Roslan Abdul Rahman, Zawawi IbrahimProblem statement: An organic material is one of the major requirements to improve living environment and the invention of materials need to consider for the best solution. This study presents an experimental investigation on pure porous from Date Palm Fibre (DPF). The effectiveness of sound absorbers depends on structural architecture of this material. This study was conducted to examine the … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 17 Jul 2012 · 8,094 accessesView PDFCite
Research ArticleOpen accessIn the abstractFabrication and Experimental Investigation of PCM Capsules Integrated in Solar Air HeaterMahmud M. Alkilani, Kamaruzzaman Sopian, Sohif MatProblem statement: Thermal Energy Storage (TES) process can reduce the time or rate mismatch between energy supply and energy demand. Organic latent heat materials are suitable to use as storage medium, however, the low thermal conductivity of these materials slow the thermal response during charging and discharging processes. Approach: A solar air heater integrated with (PCM) has been designed, fabricated … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 11 Jan 2012 · 7,589 accessesView PDFCite
Research ArticleOpen accessIn the abstractTermite 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 · 26,765 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysical Composition, Nutrients and Contaminants of Typical Waste Dumping SitesH. Meuser, K. S. Grewal, R. Anlauf et al.Problem statement: The composition of wastes is quite variable depending upon the generating source and mode of collection. Most of the material from the domestic activities will be organic in nature and contains essential plant nutrients, whereas the dumping material of commercial and industrial wastes usually contains appreciable amounts of heavy and potentially toxic metals and organic pollutants. Approach: Objective … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 7,753 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Converting Secondary Tropical Peat Swamp Forest into Oil Palm Plantation on Selected Peat Soil Physical PropertiesMohd Suffian Firdaus, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: The conversion of forest land into oil palm plantation is considered to be one of the causes of soil degradation and loss of tropical land forest in Southeast Asia. The objective of this study was to compare selected peat soil physical properties of secondary tropical peat swamp forest and oil palm plantation to determine the effect of forest … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 8,742 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectrical and Optical Properties of N, N`-Bis (Inaphthyl)-N,N`-Diphenyl-1,1`-Biphenyl-4,4`-Diamine as Hole Transport Layer in Organic Light Emitting DevicesM. Y. Lim, W. M.M. Yunus, Z. A. Talib et al.Problem statement: The aim of this research was to study the electrical and optical properties of N, N`-bis(Inaphthyl)-N,N`-diphenyl-1,1`-biphenyl-4,4`-diamine (NPB) organic materials often used as hole transport layer in Organic Light-Emitting Devices (OLED). Approach: The NPB layer was prepared using the thermal evaporation method. From photoluminescence spectra, two peaks at 630 and 480 nm were observed with 55 nm NPB. The … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 9,125 accessesView PDFCite
Research ArticleOpen accessIn the abstractControlling the Morphology of Nano-Hybrid MaterialsAbdullah I. Al JaafariProblem statement: It is known that layer double hydroxide is one of the nano ordered layered compounds and possesses plate-like morphology if carefully crystallized. Approach: In this study, Co-Sn LDH consisting of divalent and tetravalent cations was prepared with new morphology. XRD patterns of the prepared Co-Sn LDH showed that the interlayer spacing of the LDH was 0.78 nm and … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 7,886 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Investigation on Geomechanical Properties of Tropical Organic Soils and PeatBujang B.K. Huat, Afshin Asadi, Sina KazemianProblem statement: Organic soils and peat were believed to be geotechnically problematic due to their very high compressibility, very low shear strength and difficult accessibility. Although conventional soil mechanics theory could be applied to the soils, it was found that important anomalies existed which required special considerations. Correlations between geomechanical parameters for the soils were known to be important for … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 10,172 accessesView PDFCite
