Effect of Energy Input on Microstructural Features and Mechanical Properties of Medium Chromium Ferritic Stainless Steel Welds
Research Output | Dar Al-hikmah Library | IIUM Only

Medium chromium ferritic stainless steel conforming to AISI 430 was TIG-welded with different energy input 205J/mm ≤ HI ≤ 2304J/mm in argon shielding environment and characterized for microstructural features as well as mechanical properties. Macro profiling of the weld section show large distortion with wider HAZ as the energy input increases.

Analysis of Sensitization Profile in Medium Chromium Ferritic Stainless Steel (Fss) Welds
Research Output | Dar Al-hikmah Library | IIUM Only

The sensitization features in Ferritic Stainless Steel (FSS) welds are discussed in the present work. The welds were produced on a 1.5mm thick plate of 16wt%Cr FSS conforming to AISI 430 commercial grade, using TIG torch in argon environment at a heat flux between 1008W and 1584W and speed between 2.5mm/s and 3.5mm/s. The sensitization was evaluate

Estimation of Aerodynamic Parameters of IIUM Hybrid Airship
Research Output | Dar Al-hikmah Library | IIUM Only

The aerodynamic parameters of a preliminary IIUM low speed winged-hull airship design is investigated. The objective is to study the aerodynamic parameters of the wingedhull airship and to find the necessities of attaching wings to the existing IIUM low speed airship. The research methodology involved the use of numerical simulation and laboratory

Ganoderma Boninense Disease Detection by near-Infrared Spectroscopy Classification: a Review
Research Output | Dar Al-hikmah Library | IIUM Only

Ganoderma boninense (G. boninense) infection reduces the productivity of oil palms and causes a serious threat to the palm oil industry. This catastrophic disease ultimately destroys the basal tissues of oil palm, causing the eventual death of the palm. Early detection of G. boninense is vital since there is no effective treatment to stop the conti

Astaxanthin as a Valuable Natural Carotenoid
Research Output | Dar Al-hikmah Library | IIUM Only

Carotenoids can be obtained naturally from several sources like fruits, algae, plants, and crustaceans, contributing to varying red or yellow pigmentation. Carotenoids are acyclic substances having several transformations, leading to more than 800 compounds derived by the addition of oxygen-abundant functional groups or end group cyclisation. Hence

Resonant Breathing Biofeedback Training for Stress Reduction Among Manufacturing Operators
Research Output | Dar Al-hikmah Library | IIUM Only

The aim of this study was to examine the effect of resonant breathing biofeedback training for reducing stress among manufacturing operators. Resonant breathing biofeedback works by teaching people to recognize their involuntary heart rate variability and to control patterns of this physiological response. Thirty-six female operators from an electr

Antifungal Activity of Andrographis Paniculata Extracts and Active Principles Against Skin Pathogenic Fungal Strains in Vitro
Research Output | Dar Al-hikmah Library | IIUM Only

Context: Andrographis paniculata Nees. (Acanthaceae) is an annual herbaceous plant widely cultivated in southern Asia, China, and Europe. It is used in the treatment of skin infections in India, China, and Malaysia by folk medicine practitioners. Objective: Antifungal activity of the whole plant extracts and isolation of active principles from A. p

مساهمات اللغة العربية في أسلمة وسائل الإعلام في ماليزيا = the Contributions of Arabic Language in the Islamization of Mass Media in Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

As time passed, Arabic Language has become a worldwide language which it has become one of the five most spoken language in the world. Among them is Malaysia, where Arabic Language is widely taught in schools and universities. Especially we can see the widespread use of Arabic Language in the mass media of Malaysia and constantly relate with religi

Electrical Behaviour of yttrium-Doped Potassium Sodium Niobate Thin Film for Piezoelectric Energy Harvester Applications
Research Output | Dar Al-hikmah Library | IIUM Only

This study evaluates how the electrical characteristics of potassium sodium niobate, K0.5Na0.5NbO3 (KNN) thin film, are affected by yttrium doping. For the KNN thin films doped with yttrium, the secondary phase was not observed, which means that the films preserved the orthorhombic lattice. Yttrium doping affected the grain structure where microsco

Squalene Recovery from Palm Fatty Acid Distillate Using Supercritical Fluid Extraction
Research Output | Dar Al-hikmah Library | IIUM Only

The objective of this research is recovery of squalene from palm fatty acid distillate (PFAD) using supercritical fluid extraction (SFE). The extraction process was performed by using the SFE and recovered squalene was analyzed from total lipid extracts using HPLC. A central composite design was used to study the effect of SFE variables namely pres
