A two-level fractional factorial design (FFD) was used to determine the effects of six factors, i.e. substrate (domestic wastewater sludge – DWS) and co-substrate concentration (wheat flour – WF), temperature, initial pH, inoculum size and agitation rate on the production of cellulase enzyme by Trichoderma harzianum in liquid state bioconversio

The hybridization of thermoplastic natural rubber based on carbon fiber (CF) and kenaf fiber (KF) was investigated for its mechanical and thermal properties. Hybrid composites were fabricated with a melt-blending method in an internal mixer. Samples with overall fiber contents of 5, 10, 15, and 20 vol % were subjected to flexural testing, and sampl

A laboratory-scale study was conducted to evaluate the feasibility of using palm oil mill effluent (POME) as a major substrate and other nutrients for maximum production of citric acid using the potential fungal strain Aspergillus niger (A103). Statistical optimization of medium composition (substrate–POME,co-substrates–wheat flour and glucose,

In this paper, novel techniques in increasing the accuracy and speed of convergence of a Feed forward Back propagation Artificial Neural Network (FFBPNN) with polynomial activation function reported in literature is presented. These technique was subsequently used to determine the coefficients of Autoregressive Moving Average (ARMA) and Autoregress

Voice identification is a task of identifying a person based on the content of information in one’s voice signal which distinguishes his/hers from voices of other people. This paper presents an educational project on a simple voice identification system, which uses two parameters of voice features: the fundamental frequency or pitch and the vocal

Abstract: Objectives: This study was aimed to examine the effect of two different media on bone marrow stem cells (BMSCs) chondrogenesis in vitro and in vivo. Methods: BMSCs were isolated from sheep and divided into two test groups and control group. Control group was cultured in medium supplemented with 10 % fetal bovine serum (FBS). Test group A

The entering of men into nursing is widely spread in around the world; Malaysia is not excluded from this scenario. The former dominated profession by female now will become free-gender occupation. As the productions of male nurse keep increasing into health care institution, the researcher feels the need to know the other health care workers’ pe

This article argues about the importance of having a good energy mix in striking balance between various types of energy resources in order to have sustainable energy supply.

Presents the sets of conditions that make nuclear energy a viable option for the future and challenges faced in realizing that option.

This paper discusses the concept and application of Shari'ah compliant contract for construction works'. A Shari'ah compliant contract refers to a contract that incorporates the Islamic belief, practice and value system in its subject matter, agreement, terms and the conditions. The paper is presented in four parts. Part one describes t
