Research ArticleOpen accessIn the author namesMechanical Strength and Durability Properties of High Performance Mortar Containing Densified Silica FumeCheah Chee Ban, Mahyuddin RamliProblem statement: Numerous data and information on pozzolanic reaction and microfiller properties of silica fume were derived from laboratory investigation on silica fume in undensified form. Currently, due to low bulk density of undensified silica fume which poses problem in transportation and handling of the material, silica fume are commercially supplied in densified form. Densification process used to increase bulk … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,956 accessesView PDF Cite

Research ArticleOpen accessIn the author namesOptimization of Mix Proportion of High Performance Mortar for Structural ApplicationsCheah Chee Ban, Mahyuddin RamliProblem statement: Mortar mix is a major construction material in fabrication of ferrocement structural elements. However, there have been scarce amount of technical data available on suitable mix proportion to achieve structural grade mortar with specific strength requirement and adequate level of workability for proper placement into construction formwork. Moreover, current practice in ferrocement construction work which uses mortar mix … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 8,810 accessesView PDF Cite

Research ArticleOpen accessIn the author namesDeoiling and Regeneration Efficiencies of Spent Bleaching ClayA. W. Nursulihatimarsyila, K. Y. Cheah, T. G. Chuah et al.Problem statement: Disposal and reuse of Spent Bleaching Clay (SBC) from palm oil processing industry is a problem of growing importance. The residual oil in the SBC can be recovered using hexane as solvent. Approach: In this study, the effect of different solid to solvent ratio on the deoiling efficiency of SBC samples from palm oil refinery and palm kernel … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 8,684 accessesView PDF Cite

Research ArticleOpen accessIn the author namesRandom Amplified Polymorphic Dna-PCR Typing of Vibrio parahaemolyticus Isolated from Local Cockles (Anadara granosa)Lesley Maurice Bilung, Son Radu, Abdul Rani Bahaman et al.Randomly amplified polymorphic DNA (RAPD) was used in this study to examine the genetic relatedness among the Vibrio parahaemolyticus strains. In the analysis by RAPD-PCR, the size for RAPD fragments ranged from 0.25 to 10.0 kb with average number of ten bands. The RAPD profiles revealed a high level of DNA sequence diversity within the Vibrio parahaemolyticus strains tested. Hence, … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 8,606 accessesView PDF Cite
