This work aims at recycling oil palm empty fruit bunches (EFB) as renewable resource. Comparative studies between artificial neural network (ANN) and Response surface methodology (RSM) in fermentation media optimization for the production of citric acid from EFB have been conducted. In a previous work, RSM method was employed to optimize the media

Psychophysical studies are elemental ways to describe sound perception which includes the identification of perceptual differences in children, young and older adults. This study summarizes various psychophysical abilities with aims to provide better understanding in the perceptual development of normal hearing subjects. This study investigated fre

Palm oil mill effluent discharged by the oil palm industries is considered as the mixed of high polluted effluent which is abundant (about 20 million tonnes year-1) and its effect contributes to the serious environmental problems through the pollution of water bodies. Approach: The aim of this study was to identify the potential of low cost substra

Constant rate microfiltration experiments are conducted in purification of sewage secondary effluent pretreated with polyaluminum chloride (PAC). Monolithic ceramic membrane having a nominal pore size of 1.0 micro meter with 19 tubular channels is used as a filter medium. The system is capable of selecting the required mode of membrane cleaning, i.

A 250MHz Surface-Transverse Wave (STW) resonator is employed as a sensor element for the detection of DF-1 cells. STWs are horizontally polarized shear waves which are generated and detected by the interdigitated transducers (IDTs) similar to surface-acoustic wave (SAW) resonators. Detection of chemical and biological agents in aqueous solutions is

Electro-osmosis is especially effective in removing liquid from sludge of colloidal particles for which conventional mechanical dewatering is not very successful. This work presents results of experimental work carried out to study and analyze the combined operation of electro-osmotic dewatering (EOD) and mechanical expression (ME) by use of the Te

Traditionally a telecommunication device, the emerging application of acoustic wave devices as sensors is rapidly gaining attention due to its high sensitivities. In this work, a comparative study of surface (SAW) and bulk (BAW) acoustic wave biosensors is presented. The MEMS SAW resonator is formed using a lithium niobate substrate with Al electro

Fish are popularly recognized as an excellent source of lipids that are composed of a wide range of important fatty acids. Fish also contain good quality protein and are an adequate source of many vitamins (e.g. fat soluble A, D, E and the water soluble B-complex), in addition to important minerals such as calcium and phosphorous. We recently inves

In this work, a finite element modeling of surface acoustic wave biosensors is presented. These resonators are formed using a lithium niobate substrate with Al electrodes as the interdigitated transducers. A study has been made to compare the efficiency and sensitivity of the acoustic wave biosensors in analyzing the DF-1 cells. DF-1 animal cell we
