Research ArticleOpen accessIn the author namesDynamic Mathematical Modelling of Reaction Kinetics for Cyclodextrins Production from Different Starch Sources Using Bacillus macerans Cyclodextrin GlucanotransferaseSyahinaz Shahrazi, Suryani Saallah, Mohd Noriznan Mokhtar et al.This study relates to the mathematical modelling of enzymatic production of Cyclodextrins (CDs) by Cyclodextrin Glucanotransferase (CGTase) from Bacillus macerans. The experiments were carried out in batch mode using different starch sources and the results were used to estimate unknown parameters using linearization and dynamic simulation methods. α- and β-CD produced from tapioca were found to give the highest Michaelis-Menten … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 20 Jun 2013 · 7,912 accessesView PDFCite
Research ArticleOpen accessIn the author namesTwist Springback Measurement of Autonomous Underwater Vehicle Propeller Blade Based on Profile DeviationAhmad Baharuddin Abdullah, Mohd Sapuan Salit, Zahurin Samad et al.Geometrical defects that are attributable to springback are among the major defects induced by the sheet metal forming process. Such defects are critical for sections with varying thickness, such as Autonomous Underwater Vehicle (AUV) propeller blades. In this study, the springback in the twist-bending of an AA6061 propeller blade was quantified by comparing the targeted and manufactured profiles obtained using … …American Journal of Applied Sciences, Vol. 10, Issue 5 · 31 May 2013 · 7,383 accessesView PDFCite

This study evaluated the manifestation of food insecurity in households in Abia … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 16 Aug 2011 · 8,091 accessesView PDFCite
Research ArticleOpen accessIn the author namesPerformance of IBS Precast Concrete Beam-Column Connections Under Earthquake Effects: A Literature ReviewPatrick Tiong Liq Yee, Azlan Bin Adnan, Abdul Karim Mirasa, Ahmad Baharuddin Abdul RahmanProblem statement: Despite demonstrating rather much benefits comparing to the conventional cast-in-place construction, the acceptance level of precast concrete building is still reportedly low in Malaysia. The implication imposed by stricter seismic design provisions would only worsen the matter. Approach: The main objective of this study was to identify the most appropriate type of beam-column connections to be introduced to … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 31 Jan 2011 · 17,566 accessesView PDFCite

Research ArticleOpen accessIn the author namesMolecular Characterization of Fusarium Oxysporum F. Sp. Cubense of BananaS. K. Leong, Z. Latiffah, S. BaharuddinProblem statement: Morphological characterization of Fusarium species which emphasize on microscopic and cultural characteristics are not sufficient to characterize Fusarium Oxysporum F. sp. Cubense (FOC) from banana as these characteristics could easily influence by environmental factors. As an alternative molecular methods were used to characterize and to assess genetic variation of FOC from different banana cultivars. Knowledge on the genetic … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 9,272 accessesView PDFCite
