Phytochemical and bioactivity studies of the leaves of Melastoma malabathricum L. (Melastomataceae) have been investigated. The n-hexane extract yielded α-amyrin, patriscabatrine and auranamide, ethyl acetate extract gave quercetin and quercitrin, and methanol extract gave quercitrin and kaempferol-3-O-(2”,6”-di-O-p-trans-coumaroyl)glucoside.

The automated auditory brainstem response (AABR) is an important tool for detecting hearing impairment in newborns, but it is often hindered by unacceptably long test times. On average, it takes 3 to 5 minutes per infant to acquire sufficient data to determine if an AABR waveform is present or absent. The successful reduction of this average test t

This study was done in order to determine the presence of antioxidant and the level of antioxidant activity of garlic (Allium sativum) and shallot (Allium cepa). Garlic and shallot have been the most common ingredients in the preparation of Malaysian cuisines and it has been long-held belief that these two Allium species posses many medicinal prope

This work addresses the structural weaknesses that threaten to derail counterterrorism efforts by the Malaysian government. It also highlights the links between various pre-September 11 security issues in Southeast Asia and the terrorism threat facing Malaysia at present. The limitations of the current counterterrorism approach by the government ar

In the aircraft industry, manufacturers have to decide quickly whether an impacted sandwich needs repairing or not. Certain computation tools exist at present but they are very time-consuming and they also fail to perfectly model the physical phenomena involved in an impact. In a previous publication, the authors demonstrated the possibility of rep

This paper aims at exploring, discussing and analyzing some major issues in teaching creative thinking skills (CTS) based on IIUM experience.1 These issues are challenges encountering trainers and lectures in teaching (CTS), strategies to overcome these challenges, and future implications proposed to enhance the process. It is well recognized world

In this study a core crush criterion is proposed to determine the residual strength of impacted sandwich structures. The core of the sandwich is made of a Nomex Honeycomb core and the faces are laminated and remain thin. The mechanism of failure of this kind of structure under post-impact compressive loading is due to interaction between three mech

Pulsed eddy current (PEC) is a new emerging nondestructive testing (NDT) technique using a broadband pulse excitation with rich frequency information and has wide application potentials. This technique mainly uses feature points and response signal shapes for defect detection and characterization, including peak point, frequency analysis, and stati

A new reliable algorithm based on an adaptation of the standard Homotopy-Perturbation Method (HPM) is presented. The HPM is treated,for the first time, as an algorithm in a sequence of intervals (i.e., time step) for finding accurate approximate solutions of linear and nonlinear systems of ODEs. Numerical comparisons between the multistage Homotopy
