Hanafi [1] and Asep [2] et. al. have shown that the presence of water vapor in oxidation environment enhances the oxygen transport along the precipitates oxide/metal interface. This explains the reason of accelerated oxidation rates and anomalous oxidation behavior in water vapor condition. Oxygen potential on the surface of oxide during the oxidat

Many studies1-3 have shown that oxidation rates in humid environment are higher than in dry environment. The formation of Cr2O3 scale during high temperature oxidation is beneficial in protecting metals from severe oxidizing environment. A dilute solid solution, such as Fe-Cr alloy with small Cr concentrations, forms internal oxide of Cr2O3 when ex

A kinetic study of solid state bioconversion for the production of citric acid from oil palm empty fruit bunches was conducted. Locally isolated Aspergillus niger IBO-103MNB (IMI396649) was used for this study. As citric acid production typically exhibits product-associated kinetics, both fungal growth in term of protein content and citric acid pro

Discussing the relevancy of nuclear power plant.

An investigation was carried out to determine the production of lignocellulitic enzymes: ligninase and cellulases (exo-cellulase and edo-cellulase) and their effects during the bioconvertion of empty fruit bunches (EFB) for the production of citric acid. The result shows that the maximum production of citric acid was 181.25 g/kg of dry EFB from A.

This paper presents the results of experimental investigations conducted on a vertical machining centre (VMC) using spindle speed, feed rate, and depth of cut as machining variables to ascertain the effectiveness of TiAlN insert in end milling of hardened steel AISI H13, under workpiece preheated conditions and hence a statistical model was develop

OBJECTIVE The objectives of this project are:  To clone stem bromelain from pineapple  To sequence the cloned bromelain gene  To study the stem bromelain characterization  To express the bromelain gene in the expression vector  To purify the expressed bromelainMOLECULAR CLONING, SEQUENCING, PURIFICATION AND PURIFICATION OF STEM BROME

Hardened materials like AISI H13 steel are generally regarded as difficult to cut materials because of their high hardness due to high carbon content, which however allows them to be used extensively as the hot working tools like, dies and moulds. The challenges in machining this steel in hardened state led to many research works dedicated towards

Silicon has been widely used in different branches of industrial engineering. Most application of silicon is in computer parts or hardware especially for the production of integrated circuit (IC) chips. Machining of silicon is a big challenge and expensive affair because of it inherent brittleness which is a major limitation as the process of remov

Minggu lalu Pendaftar Pertubuhan (ROS) mengejutkan semua pihak dan mungkin Datuk Seri Chua Soi Lek sendiri apabila beliau menyatakan bahawa Chua adalah timbalan presiden MCA yang sah. Sebelum ini musuh politiknya yang juga Presiden MCA Datuk Seri Ong Tee Keat menggunakan mekanisme dalam parti itu untuk memecat Chua dan kemudian melantik salah seora
