Eurycoma spp., also known locally as Tongkat Ali is considered the most popular medicinal plant in Malaysia. The tremendous attention put to it by the public for its medicinal properties has led to its non-selective harvesting at a very alarming rate. Concerted efforts by a number of institutions in the country have been initiated to manage, conser

Maghemite nanoparticles were synthesised using the co-precipitation method and characterised by various techniques, including X-ray diffraction, transmission electron microscopy, alternating gradient magnetometry, dynamic light scattering and zeta potential. The stability of the suspension was monitored by measuring the particle size distribution a

Purpose: To investigate the microscopic diffusion properties of formalin-fixed breast tissue. Methods: Diffusion microimaging was performed at 16.4T with 40-mm isotropic voxels on two normal and two cancer tissue samples from four patients. Results were correlated with histology of the samples. Results: Diffusion-weighted images and mean diffusivit

In managing shortness of breath due to asthma or related symptoms, the practice in the emergency department is often uniform across the country. Patients who attend unannounced, ‘walk-in’ is the medical lingo, with symptoms suggestive of a sudden asthma attack will be directed to the asthma bays for immediate treatment. These patients are often

This paper presents a lab-on-chip biosensor containing an enclosed fluidic cell culturing well seeded with live cells for rapid screening of toxicants in drinking water. The sensor is based on the innovative placement of the working electrode for the electrical cell–substrate impedance sensing (ECIS) technique as the top electrode of a quartz cry

The upgrade recycling of cast-iron scrap chips towards β-FeSi2 thermoelectric materials is proposed as an eco-friendly and cost-effective production process. By using scrap waste from the machining process of cast-iron components, the material cost to fabricate β-FeSi2 is reduced and the industrial waste is recycled. In this study, β-FeSi2 speci

This study applies the clonal selection algorithm (CSA) in an artificial immune system (AIS) as an alternative method to predicting future rainfall data. The stochastic and the artificial neural network techniques are commonly used in hydrology. However, in this study a novel technique for forecasting rainfall was established. Results from this stu

The upgrade recycling process of cast-iron scrap chips toward β-FeSi2 is regarded as an eco-friendly and cost-effective production process. It is useful for reducing the material cost in fabricating β-FeSi2 by utilizing the waste that is obtained from the manufacturing process of cast-iron components. In this research, β-FeSi2 was successfully o

Thermostable enzymes have several benefits in various industrial applications. Cellulase has been used in various industries such as textile, detergent, food and feed, pulp and paper, and recently in bioethanol production. The major aim of this work is to predict the potential site for mutagenesis computationally and produce the mutant experimental

Cellulose is the most abundant biopolymer on earth. Enzymatic degradation of this biopolymer is a crucial step toward its conversion to bioethanol. However the current cellulosic enzymes are unable to withstand high temperature of industrial processes. In this work we use computer simulations to predict thermostable endoglucanase. The molecular dyn
