Research ArticleOpen accessIn the abstractChemical and Physical Characteristics of Cocopeat-Based Media Mixtures and Their Effects on the Growth and Development of Celosia cristataYahya Awang, Anieza Shazmi Shaharom, Rosli B. Mohamad, Ahmad SelamatProblem statement: Cocopeat is considered as a good growing media component with acceptable pH, electrical conductivity and other chemical attributes but it has been recognized to have high water holding capacity which causes poor air-water relationship, leading to low aeration within the medium, thus affecting the oxygen diffusion to the roots. Incorporation of coarser materials into cocopeat could improve the … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 19,015 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordInfluence of Chemical Properties on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: It is important to investigate the seriousness of degradation of peat swamp forest caused by skidding system in terms of its function as a carbon sink. In this study, we formulated assumptions that conditions of our research site before the introduction of skidding system were in their natural states, thus that changes measured are clearly caused by skidding … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 7,919 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordCohesiveness and Flowability Properties of Silica Gel PowderE.C. Abdullah, A.M. Salam, A.R. AzizProblem statement: The measurement of powder flowability is a major concern for most industrial processes that deal with the handling of bulk solids as raw materials, intermediates, or products. Approach: The influence of particle size on the flowability of silica gel was investigated using aerated and non-aerated methods. The aerated method involved the measurement of the Hausner Ratio (HR) and … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 15,536 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPreparation of WO3 Nanoparticles Using Cetyl Trimethyl Ammonium Bromide Supermolecular TemplateNilofar Asim, S. Radiman, M. Ambar bin YarmoProblem statement: WO3 is one of the most interested metal oxides because of its application as catalysts, sensors, electrochromic devices, ceramic, solar cell, pigments and so on. More investigation is needed to find the good and low cost method for preparation of WO3 nanoparticles with uniform morphology and narrow distribution using a surfactant mediated method. Approach: In this study, the … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,703 accessesView PDF Cite
