Estimation of Mach Numbers in Supersonic Jets Using Schlieren Images
Research Output | Dar Al-hikmah Library | IIUM Only

supersonic nozzles are commonly used in mechanical and aerospace engineering applications for decades. Therefore, it is essential to study their characteristics and discover techniques to measure relevant flow properties with minimal investment in terms of time, money, and effort. Supersonic jets are composed of shock waves and expansion waves, mak

Early Procalcitonin Dynamics in Critically Ill Patients with Sepsis in a Tertiary Icu
Research Output | Dar Al-hikmah Library | IIUM Only

Introduction: In critically-ill patients, procalcitonin has been studied as an assessment of appropriateness of therapy, evaluation of sepsis severity and tailoring antibiotic prescription. Objectives: We evaluated serum PCT levels relative to patient characteristics, infectious status, and presence of septic shock, SOFA score and mortality. The se

Experimental Study of Midplane Jet Evolution in Multiple Jets at Mach 2.0
Research Output | Dar Al-hikmah Library | IIUM Only

The flowfield characteristics are experimentally studied in the inter-nozzle region of free jets from twin and triple supersonic nozzles. The nozzle is designed for Mach number 2.0, and the inter-nozzle spacing is twice the nozzle exit diameter. The impact of multiple jets on the flow characteristics such as the jet spread, supersonic jet core, and

An Antifungal Body Soap from Stem Bark of Entada Spiralis Ridl.(Akar Sintok) as a New Cosmeticeutical Product
Research Output | Dar Al-hikmah Library | IIUM Only

The stem bark of Entada spiralis Ridl. locally known as “sintok” has been used traditionally for generations as washing agent, syampoo and body soap. The formation of foam when stem bark agitated in water gave indication of the presence of saponin. The phytochemical investigations of methanolic extract and its fraction discovered saponins and t

Water Transportation from Islamic Perspectives
Research Output | Dar Al-hikmah Library | IIUM Only

Water transportation is one of the various types of transportation modes that are widely used nowadays. This paper deals with the Islamic perspectives of water transportation. In this paper, two categories of water transportation which are inland water transport (IWT) and ocean transport are been explained. IWT is energy efficient and cheaper mode

Liquidity Risk Management and Financial Performance in Malaysia: Empirical Evidence from Islamic Banks
Research Output | Dar Al-hikmah Library | IIUM Only

Liquidity risk arises from maturity mismatches where liabilities have a shorter tenor than assets. A sudden rise in the borrowers‟ demands above the expected level can lead to shortages of cash or liquid marketable assets (Oldfield and Santamero, 1997). This paper aims to analyse the liquidity risks and disclosure as well as to draw the relations

The Effect of Information Needs’ Program on Anxiety Among Family Members in the Intensive Care Unit (Icu)
Research Output | Dar Al-hikmah Library | IIUM Only

Background: Admission or hospitalization of a relative to Intensive Care Unit (ICU) can result in many psychosocial problems such as anxiety and trigger perceived needs of patient and their family members. Critical care nurses play a vital role in identifying needs and help them by providing information in this crisis period to reduce anxiety level

Optimization of Precision Grinding Parameters of Silicon for Surface Roughness Based on Taguchi Method
Research Output | Dar Al-hikmah Library | IIUM Only

Silicon being a typical hard-brittle material is difficult to machine to a good surface finish. Although ductile-mode machining (DMM) is often employed to machine this advanced material but this technique requires the use of expensive ultra-precision machine tools therefore limiting its applicability. However, by proper selection of grinding parame

Symmetrical Analysis and Evaluation of Differential Resistive Sensor Output with Gsm/gprs Network
Research Output | Dar Al-hikmah Library | IIUM Only

Differential Resistive Sensor Interface is industrially significant for GSM/GPRS transmission to a mobile phone in order to enhance communication technique. The Sensor output needs to be made digital, hence the need for a microcontroller and the signal is displayed in a PC as output voltage, sensed parameter, x. A frequency and voltage output are o

Iterative Spatial Sectoring Algorithm: a Computer Based Approach to Determining Area of Irregular Closed Space and Tumor Volume
Research Output | Dar Al-hikmah Library | IIUM Only

Measuring the properties of regular shapes like triangles, parallelogram, and geometric figures like circle, and spheres have well established methods and formulae. On the contrary, measuring the parameters of irregular shapes and particularly area of irregular closed space with snaky or wobbled edge is yet to have a definitive and assured approach
