Effects of Dlc/tialn-Coated Die on Friction and Wear in sheet-Metal Forming Under Dry and oil-Lubricated Conditions: Experimental and Numerical Studies
Research Output | Dar Al-hikmah Library | IIUM Only

Experimental and numerical analyses were conducted to explore the influence of DLC/TiAlN-coated die surfaces in sheet-metal forming under dry and oil-lubricated conditions. In this study, ironing and deep-drawing experiments were performed to determine the potential of the DLC/TiAlN coating in the sheet forming of stainless steels under different t

Prevalence of Depression Among Elderly and its Predictors; a Cross Sectional Study in Community Felda Bukit Goh, Kuantan, Pahang.
Research Output | Dar Al-hikmah Library | IIUM Only

Background: The world’s population is ageing rapidly. Older people are at risk of having mental illnesses particularly depression but it is often misdiagnosed and undertreated. It affects general wellbeing and daily functions of the patients. Objectives: To measure the prevalence of depression and its associated factors among elderly living in FE

Aluminum Foil Waste as Catalyst for Esterification of Waste Cooking Oil
Research Output | Dar Al-hikmah Library | IIUM Only

In this study, aluminum chloride hexahydrate (AlCl3.6 H2O) was derived from aluminum foil waste as a heterogeneous acid catalyst in the esterification of waste cooking oil. The parameters of catalyst loading (2–8 wt%), ultrasonic frequency (12–40 kHz), and reaction time (15–60 min) were optimized for maximum biodiesel yield production. Under

Development of Inert Ceramic for Industrial Application Based on Ternary Phase Diagram of Potassiun oxide-Aluminum oxide-Silicon Dioxide
Research Output | Dar Al-hikmah Library | IIUM Only

An example of sintered inert ceramic is ceramic balls as catalyst support media. The composition of the ceramic is regulated by Universal Oil Products (UOP) standard. The requirement of the chemical composition will therefore determine the range of sintering temperature, number of phases or crystal during sintering, and the weight percent of starti

Development of Cao/pva Catalyst from Fish Bone for Biodiesel Production
Research Output | Dar Al-hikmah Library | IIUM Only

In this study, calcium oxide were synthesized from fish bone waste and the optimum condition: catalyst amount, reactor temperature, and methanol to oil ratio (molar) for biodiesel production were studied. The calcium oxide (CaO) derived from fish bone wastes was then supported on polyvinyl alcohol (PVA) to easily separate the catalyst and biodiesel

Convergence and Error Analysis of a bi-Quadratic Triangular Galerkin Finite Element Model for Heat Conduction Simulation
Research Output | Dar Al-hikmah Library | IIUM Only

Present paper elaborates solution of partial differential equations (PDE) of two dimensional steady state heat conduction by using a bi quadratic triangular Galerkin’s finite element method (QGFEM). The steady state heat distribution is modeled by a two-dimensional Laplace partial differential equations. A six-node triangular element model is dev

Contemporary Structuring of Corporate Waqf via Islamic Real Estate Investment Trusts (i-Reits): is it Viable?
Research Output | Dar Al-hikmah Library | IIUM Only

Waqf or Islamic endowment is an important institution in the social sector (ijtimia’i sector) of the Islamic economic system that has contributed significantly towards socio-economic and social development since the early days of Islam. There is an abundance of historical evidence that has shown the commendable contribution of waqf as a primary s

Production of Coloured Callus in Orthosiphon Stamineus Benth and Antioxidant Properties of the Extracted Pigments
Research Output | Dar Al-hikmah Library | IIUM Only

Purpose The purpose of the present study is to understand the role of auxin and cytokinin in stimulating the production of pigmented callus in Orthosiphon stamineus and to gain correlation between the callus colours with their antioxidant capacity and bioactive constituents. Design/methodology/approach In this study, plant tissue culture was used t

The Impact of Philosophical Inquiry Method on Classroom Engagement and Reasoning Skills of Low Achievers
Research Output | Dar Al-hikmah Library | IIUM Only

This research project attempted to investigate the impact of applying philosophical inquiry method of teaching on classroom engagement and reasoning skills of low achievers. Low achievers are those who have the potential to succeed but lagged behind because of several factors that demotivate them to perform at their highest ability. In this study,

The Book of Sale: Being the Second Chapter of Majallah Ahkam al-Adliyah
Research Output | Dar Al-hikmah Library | IIUM Only

Islamic jurisprudence and its law trace their origins back to the life of the Prophet Muhammad (PBUH) with the start of Holy Revelation (waḥī) from the cave of Ḥirā’ on the outskirts of Makkah. The start was from the Holy Commanad of iqrā’ which literally means read. Hundreds of rulings, principles, maxims were laid down during the life
