Iinfluence of Mg/ctab Ratio on the Structural, Physicochemical Properties and Catalytic Activity of Amorphous Mesoporous Magnesium Silicate Catalysts
Research Output | Dar Al-hikmah Library | IIUM Only

This study investigated the physicochemical and catalytic properties of mesoporous magnesium silicate catalysts prepared at various Mg/CTAB ratio (0.25, 0.50, 0.75 and 1.00). The XPS analysis detected a mixture of enstatite and magnesium carbonate species when the Mg/CTAB ratio was 0.25, and 0.50. A mixture of forsterite and magnesium carbonate spe

Modelling of patient-Specific Femur with Osteogenesis Imperfecta to Determine the Fracture Risk Under Various Loads
Research Output | Dar Al-hikmah Library | IIUM Only

Osteogenesis imperfecta (OI) is a fragile bone disease characterized by easy fractures. The femur consists of cortical and cancellous bone, each with different mechanical properties. Bone fractures often occur throughout patients’ lifetime. However, doctors still have no quantitative method to predict fractures. Therefore, this project’s purpos

Stress Analysis of thin-Walled Laminated Composite Beams Under Shear and Torsion
Research Output | Dar Al-hikmah Library | IIUM Only

An educational software which can aid students in the stress analysis of thin wall open sections made of composite material has been developed. The software enables students to easily calculate stresses in different shapes of thin walled open section and evaluate the stresses in each ply under shear and torsion. Results obtained through this softwa

Finite Element Analysis of Tibia with Osteogenesis Imperfecta: the Influence of Considering Cancellous Bone in Model Reconstruction
Research Output | Dar Al-hikmah Library | IIUM Only

The paper aims to develop the finite element (FE) models of tibia with Osteogenesis Imperfecta (OI) based on a patient-specific computed tomography (CT)-images. Two types of FE model have been developed. The first model was set the tibia bone as a single solid model whereas the second model consists of cortical bone and cancellous bone. The develop

Complexity Analysis of Quranic Chapters for Word Cloud Generation
Research Output | Dar Al-hikmah Library | IIUM Only

Word cloud analysis is often used to identify important words within a text. The analysis itself is usually based on frequency analysis, where the most frequent words in a text may be deemed most important. However, words that are frequent may be centered in certain sections only; therefore, it is argued that word cloud analysis based on fractal di

Numerical and Experimental Study on the Effect of cab-Extender on the Flow Characteristics of a tractor-Trailer
Research Output | Dar Al-hikmah Library | IIUM Only

The aerodynamic drag on trucks can be reduced by use of active and passive techniques. In this work a passive method of using a cab-extender that is attached to the rear of the tractor is attempted. This cab-extender will help in reducing the drag force that act on the truck by minimizing the gap between the tractor and trailer. In this study, a tr

Effect of Thermoplastic Polyurethane (Tpu) on the Thermal and Mechanical Properties of Polylactic Acid (Pla)/ Curcumin Blends
Research Output | Dar Al-hikmah Library | IIUM Only

Polylactic acid (PLA) is known to be brittle by nature and thus limits the flexibility of the polymer. A possible solution to enhance the flexibility of PLA is to add a flexible polymeric based material such as thermoplastic polyurethane (TPU). In this study, 30-50 wt% of TPU was added into PLA/curcumin blends to improve its flexibility. Thermal an

Educational Software for Stress Analysis of Idealized Closed Thin Walled Sections
Research Output | Dar Al-hikmah Library | IIUM Only

Aerospace structures are typical semi-monocoque structures that are made up of thin-walled closed section reinforced with stiffeners. Stress analysis of such closed thin-walled structures which are statically indeterminate is tedious and time consuming. An educational software which can aid students in stress analysis of such idealized thin-walled

Measuring Attitude Towards Learning Science in Malaysian Secondary School Context: Implications for Teaching
Research Output | Dar Al-hikmah Library | IIUM Only

The aim of education is to ensure a holistic development towards knowledge and well-being. Despite exhaustive effort on embedding twenty-first century skills in science teaching, students show lack of interest to learn and pursue their science careers. This present study has attempted to develop an instrument for measuring attitude towards science

News Diffusion of a Significant Event: How Malaysians and Indonesians Learnt of the Indonesia Airasia Qz8501 Tragedy
Research Output | Dar Al-hikmah Library | IIUM Only

This paper examines how a significant event is diffused in two different countries. Using the News Diffusion as a theoretical perspective, the study initially focused on the role of media in influencing the spreading of information during an enfolding aviation disaster. Taking the 2014 Indonesia AirAsia QZ8501 crash as a significant event, the rese
