Analytical Investigation of step-Square Wave in Time and Frequency Domain Using Transform Equations
Research Output | Dar Al-hikmah Library | IIUM Only

A unit step function can be used for generating a pulse of given width and height. The same pulse can be used for generating a stepped waveform of known levels and a given width in time-domain which when translated to frequency or complex S-domain provides the fundamental constituent frequencies. This paper is about studying the frequency of the ab

High Voltage Discharge Profile on Soil Breakdown Using Impulse Discharge
Research Output | Dar Al-hikmah Library | IIUM Only

Grounding terminals are mandatory in electrical appliance design as they provide safety route during overvoltage faults. The soil (earth) been the universal ground is assumed to be at zero electric potential. However, due to properties like moisture, pH and available nutrients; the electric potential may fluctuate between positive and negative valu

Discharge Current Distribution in Stratified Soil Under Impulse Discharge
Research Output | Dar Al-hikmah Library | IIUM Only

The mobility of charge particles traversing a material defines its electrical properties. Soil (earth) have long been the universal grounding before and after the inception of active ground systems for electrical appliance purpose due to it semi-conductive properties. The soil can thus be modelled as a single material exhibiting semi-complex induct

anti-Atherosclerotic Effects of Eurycoma Longifolia (Tongkat Ali) in Rats Fed on high-Fat Diet
Research Output | Dar Al-hikmah Library | IIUM Only

Atherosclerosis in cardiovascular disease (CVD) is a growing health problem, especially in developing countries. Hyperlipidemia is known as a dominant risk factor for the development of atherosclerosis. This study was designed to investigate the effects of Eurycoma Longifolia (EL) also known as Malaysian Ginseng/Tongkat Ali on the testosterone leve

The Cholesterol Lowering Effects of Eurycoma Longifolia Jack (Tongkat Ali) Root Extract in Male Rats
Research Output | Dar Al-hikmah Library | IIUM Only

Background: To investigate the effect of Eurycoma longifolia Jack root extract on serum lipids in rats. Methods: Twenty-six mature male albino Wistar rats were used in this study. A group of 18 rats were fed a high fat and high cholesterol diet for 4 weeks, after which their lipid profile was compared to the control group, who were kept on a normal

Depression, Anxiety and Stress Among Diabetic and non-Diabetic Patients with Periodontitis
Research Output | Dar Al-hikmah Library | IIUM Only

The aim of this study is to determine the prevalence and severity of depression, anxiety and stress among diabetic patients with periodontitis and to assess the association of emotional disturbances with the severity of periodontitis. A total of 72 diabetic patients with periodontitis and 87 non diabetic patients with periodontitis who attended Kul

Changes in Leptin in Relation to Increased Testosterone Levels Associated with Eurycoma Longifolia Jack (Tongkat Ali) Root Extract Consumption in Male Rats
Research Output | Dar Al-hikmah Library | IIUM Only

Objectives: Eurycoma longifolia jack root extract has been known for its aphrodisiac and anabolic properties. Our study aimed at investigating the effects of this extract on the serum leptin in relation to the well-known effects on testosterone levels of male rats. Methodology: Twenty-four mature male Albino Wistar rats were used in this study. The

Development of Discrete Event System (Des)-based Controller
Research Output | Dar Al-hikmah Library | IIUM Only

The importance of robotic devices for upper-limb rehabilitation therapy has been underscored by clinical evaluation of some existing robotic platforms. The devices have been used largely with the aid of expert human therapists who are required to specify appropriate therapy placement and adjust the therapy in consonant with the patient physical rec

Effect of carbon-Based Nanomaterial on Growth of Microalgae and Production of Exopolysaccharides
Research Output | Dar Al-hikmah Library | IIUM Only

Microalgae are a source of numerous compounds that can be used in different industries. Significantly, microalgae can produce exopolysaccharides (EPS) and the synthesis of EPS can be amplified under several stress conditions. Carbon- based nanomaterials have attracted great deal of interests by researcher due to many unique properties (i.e. chemica
