Dual Modification of Starch via Partial Enzymatic Hydrolysis in the Granular State and Subsequent Hydroxypropylation
Research Output | Dar Al-hikmah Library | IIUM Only

The effect of enzymatic pretreatment on the degree of corn and mung bean starch derivatization by propylene oxide was investigated. The starch was enzymatically treated in the granular state with a mixture of fungal R-amylase and glucoamylase at 35 °C for 16 h and then chemically modified to produce enzyme-hydrolyzed-hydroxypropyl (HP) starch. Par

Statistical Optimization of Process Conditions for Cellulase Production by Liquid State Bioconversion of Domestic Wastewater Sludge
Research Output | Dar Al-hikmah Library | IIUM Only

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

Mechanical Properties and Dynamic Mechanical Analysis of thermoplastic-Natural-rubber-Reinforced Short Carbon Fiber and Kenaf Fiber Hybrid Composites
Research Output | Dar Al-hikmah Library | IIUM Only

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

Bioconversion of Palm Oil Mill Effluent for Citric Acid Production: Statistical Optimization of Fermentation Media and Time by Central Composite Design
Research Output | Dar Al-hikmah Library | IIUM Only

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,

Increasing the Speed of Convergence of an Artificial Neural Network Based Arma Coefficients Determination Technique
Research Output | Dar Al-hikmah Library | IIUM Only

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

Educational Project on a Simple Voice Identification Using mel-Frequency Cepstrum Coefficients and Vector Quantization
Research Output | Dar Al-hikmah Library | IIUM Only

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

Effects of Different Media on the in Vivo Chondrogenesis of Sheep Bone Marrow Stem Cells: Histological Assessment
Research Output | Dar Al-hikmah Library | IIUM Only

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

Perceptions on Male Nurse Among Health Care Workers in Hospital Tengku Ampuan Afzan (Htaa)
Research Output | Dar Al-hikmah Library | IIUM Only

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
