Educational Software for Stress Analysis of Idealized multi-Spar Aircraft Wing
Research Output | Dar Al-hikmah Library | IIUM Only

The cross-section of a wing carries stresses such as bending, torsional and shear. The analysis in aircraft structure courses is done by assuming bending stress is only assumed to affect boom areas while shear stress only affects the skins of the cross-section. A MATLAB software has been developed with the purpose to compute the stresses and the sh

Control of Nozzle Flow in a Suddenly Expanded Duct with Micro Jets
Research Output | Dar Al-hikmah Library | IIUM Only

This paper presents results of an experimental investigation carried out to control the base pressure in a suddenly expanded axi-symmetric passage. Four micro-jets of 1 mm orifice diameter located at 900 intervals along a pitch circle diameter of 1.3 times the nozzle exit diameter in the base region were employed as active controls. The tests were

Solid Phase Microextraction Analysis of Volatile Constituents of Heated Palm Olein and Selected Oils
Research Output | Dar Al-hikmah Library | IIUM Only

Effect of heating on the development of volatile aroma constituents of palm olein and selected oils was studied. The aroma constituents of heated oils were collected using a solid-phase microextraction (SPME) headspace technique with an adsorbent of a divinylbenzene/carboxen (50/30μm) on polydimethylsiloxane (PDMS) fibre. The extracted volatiles w

High Frequency Oscillating Ventilation (Hfov) in Severe Acute Respiratory Distress Syndrome (Ards): a Case Report
Research Output | Dar Al-hikmah Library | IIUM Only

High frequency oscillating ventilation (HFOV) provides a rescue therapy for patients with refractory hypoxaemia in severe acute respiratory distress syndrome (ARDS). HFOV utilizes high mean airway pressures to maintain an open lung and low tidal volumes at a high frequency that allows for adequate ventilation while at the same time preventing alveo

Oxidative Bioconversion of ω-fatty Acid from Giant Snakehead Fish Oil
Research Output | Dar Al-hikmah Library | IIUM Only

Studies on bioconversion of ω-fatty acids in giant snakehead and mudskipper fish oil were carried out using guinea pig lung homogenate. The fish oils were incubated aerobically at 37oC in phosphate buffer solution with the addition of guinea pig lung homogenate. After incubation it was found that ca. 72-76% of arachidonic acid has been converted t

Survey on Knowledge and Practice of Intraoperative Temperature Management
Research Output | Dar Al-hikmah Library | IIUM Only

PURPOSE OF STUDY Intraoperative temperature monitoring and management is critically important to prevent complications associated with hypothermia. Satisfactory knowledge and practice in this area amongst the clinicians who are managing the patients intraoperatively is of utmost important to prevent development of hypothermia and its subsequent com

Poverty of Malaysian Rice Farmers in a Changing Climate -an Empirical Investigation in Kedah, Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

This research aims to assess the economic impact of climate change on the poverty of rice farmers in Kedah. A personal interview was conducted in a sample of 400 farm households in Kedah, Malaysia. To achieve the goal of the analysis, a logit model was used. The findings indicate that education and non-farm have major positive effect on the probabi

Bioconversion of ω-fatty Acid from Giant Snakehead (Channa Micropeltes) Fish Oil
Research Output | Dar Al-hikmah Library | IIUM Only

Study on bioconversion of ω-fatty acid contained in Channa micropeltes fish oil was carried out using guinea pig lung homogenate. The fish oil of C. micropeltes was incubated aerobically at 37oC in phosphate buffer solution with the addition of guinea pig lung homogenate. After incubation it was found that ca. 76% arachidonic acid has been convert

Switching Algorithm to Avoid Attitude Representation Singularity
Research Output | Dar Al-hikmah Library | IIUM Only

In this paper, the singularity associated with a minimal attitude parameterization using Euler angles is avoided by a switching algorithm. This algorithm is based on describing the attitude as a function of time with two sets of Euler angle sequences that possess nonconjunctive singularities. This property exists when the singularity causing values

Flow-3d Cfd Model of Bifurcated Open Channel Flow: Setup and Validation
Research Output | Dar Al-hikmah Library | IIUM Only

Bifurcation is a morphological feature present in most of fluvial systems; where a river splits into two channels, each bearing a portion of the flow and sediments. Extensive theoretical studies of river bifurcations were performed to understand the nature of flow patterns at such diversions. Nevertheless, the complexity of the flow structure in th
