Synthesis and Structure Determination of S,s′-(Naphthalen-2-ylmethyl Sulfanyl (1-p-Tolyl-ethylidene) Hydrazine
Research Output | Dar Al-hikmah Library | IIUM Only

S,S′-(Naphthalen-2-ylmethyl sulfanyl (1-p-tolyl-ethylidene) hydrazine (SNM4MA) was prepared by the condensation of S-napthalen-2-ylmethyldithiocarbazate (SNMDTC) and 4-methylacetophenone. Yellow needles of SNM4MA were obtained upon slow evaporation of a 50:50 mixture of acetonitrile and DMSO over a period of weeks. The compound crystallizes in th

Study of Operating Conditions for Biodiesel Production from Sludge Palm Oil Using Chemical Reactor
Research Output | Dar Al-hikmah Library | IIUM Only

The main challenges for biodiesel production are the cost of raw material (fats and oils) and the cost of processing. In oil palm industry there are large amounts of low grade oils that could be converted to biodiesel such as sludge palm oil (SPO). SPO is an attractive feedstock and a significant raw material for biodiesel production. The use of SP

Study of Operating Conditions for Biodiesel Production from Sludge Palm Oil Using Chemical Reactor
Research Output | Dar Al-hikmah Library | IIUM Only

Biodiesel is receiving an increased attention because of increases in crude oil prices, limited resources of fossil oil and environmental concerns. There has been renewed focus on using vegetable oils and animal fats to make biodiesel fuels. The main challenges in biodiesel industry are its production cost and limited availability of fats and oils

Daya Anti Bakteri Ekstrak Daun Sisik Naga Dibandingkan dengan Ekstrak Daun Saga, Daun Sirih dan Kayu Manis Terhadap Isolat Bakteri dari Penderita Periodontitis Kronis (Antibacterial Effect of Drymoglossum Piloselloides, Abrus Precatoris, Piper Bettle and Cinnamon Aldehyde on Isolated Bacteria from Periodontitis Chronic Patients)
Research Output | Dar Al-hikmah Library | IIUM Only

Drymoglossum piloselloides, Abrus precatoris, Piper bettle and Cinnamon aldehyde have been traditionally used in dentistry. However, there are not many scientific research on investigating those leafs and their therapeutic efficacy to bacteria causing periodontitis. Aims: to investigate antibacterial of extracted of Drymoglossum piloselloides, Abru

urban-Rural Differentials of non-Communicable Diseases Behavioural Risk Factors Among Adult People in Northeastern Bangladesh
Research Output | Dar Al-hikmah Library | IIUM Only

Background: The rapid social, cultural and economic changes in Bangladesh have given rise to a number of deaths that can be attributed to non-communicable diseases. The hospital records showed that death from cardiovascular diseases accounted for more than 12 percent of all deaths. Objectives: This study was undertaken to generate information that

Prevalence of Cardiovascular Risk Factors in a Selected Community at Kuantan, Pahang, Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

Hypertension and obesity are established and independent risk factors for cardiovascular diseases. There are important inter-relationships between these two factors that may explain the aetiology of cardiovascular diseases. To determine the prevalence of hypertension and obesity in a rural community setting in Malaysia, and to identify their associ

Application of taylor-Newton Homotopy Method for Solving Electrical Engineering Design Problem
Research Output | Dar Al-hikmah Library | IIUM Only

We describe simple implementations of homotopy (also called continuation) algorithm for determining the proper resistor to dissipate energy at a specified rate of an electric circuit. Homotopy algorithm can be considered as a developing of the classical methods in numerical computing such as Newton- Raphson and fixed point methods. In homoptopy met

A Hmrsvp Approach to Support Qos Challenges in Mobile Environment
Research Output | Dar Al-hikmah Library | IIUM Only

The current Internet architecture with its best effort service model is inadequate for real time applications that need certain Quality of Service (QoS) assurances. Several QoS models are proposed, however, these models were proposed for static environment. The main aim of this paper is to propose a set of protocols that enable the support of seaml

Biodiesel Production from Sludge Palm Oil by Ultrasonic Energy
Research Output | Dar Al-hikmah Library | IIUM Only

The main challenges for biodiesel production are the cost of raw material (fats and oils) and the cost of processing. In this study free fatty acid (FFAs) of sludge palm oil has been converted to fatty acid methyl ester via acid-catalyzed reaction using ultrasonic energy. Batch esterification process of SPO was carried out to study the influence of

C1 and C2 Vertebrae Osteomyelitis: a Misleading Presentation Leading to a Fatal Outcome
Research Output | Dar Al-hikmah Library | IIUM Only

Cervical vertebral osteomyelitis is rare. While an early and correct diagnosis is critical to prevent catastrophic neurological injury, the diagnosis of cervical vertebral osteomyelitis is often difficult because of its rarity and variable symptoms. We present a case of C1 and C2 vertebrae osteomyelitis with a misleading presentation and its fatal
