Untreated Sullage from Residential Areas - a Challenge Against Inland Water Policy in Malaysia
Research Output | Dar Al-hikmah Library | IIUM Only

Malaysian water policy was mainly focusing on the protection of the inland water resources by controlling point pollution from industrial activities and domestic sewage. Contribution of pollution loading from untreated sullage is not determined yet in Malaysia. This study was conducted to evaluate the quantity and quality of sullage discharged from

Improvement of Existing Water Quality Index in Selangor, Malaysia.
Research Output | Dar Al-hikmah Library | IIUM Only

A reviesd and improved water quality index (WQI) is proposed for the State of Selangor in Malaysia. Analyses were conducted to develop the rating curve, find the new subindices and weighing factors for the selected parameters. The water quality parameters were grouped according their similarities. The class of water gained at 1K07 (Klang River stat

High Performance Liquid Chromatographic Method Development and Validation of Cimetidine in Human Plasma for Bioequivalence Study
Research Output | Dar Al-hikmah Library | IIUM Only

Purpose. The aim of this study was to develop a validated and simple method for the determination of cimetidine in human plasma for bioequivalence study. Methods. A reverse phase high performance liquid chromatography (RP- HPLC) method for the detection of cimetidine was performed from human plasma spiked with standard cimetidine. Ranitidine was us

The Effect of the Surface Roughness of Porcelain on the Adhesion of Oral Streptococcus Mutans
Research Output | Dar Al-hikmah Library | IIUM Only

Aim: Dental plaque has a harmful influence on periodontal tissue. When a porcelain restoration is fabricated and refinishing of the glazed surface is inevitable, the increase in surface roughness facilitates the adhesion of plaque and its components. The aim of this in vitro study was to evaluate the effect of surface roughness of glazed or polishe

Tunable Bandpass Filter Using RF MEMS Switches
Research Output | Dar Al-hikmah Library | IIUM Only

A band pass tunable RF filter is proposed by using Radio Frequency (RF) Microelectro Mechanical Systems (MEMS). The tunability is obtained by using capacitive MEMS switches that can be tuned within the bandwidth of 3.6 GHz to 4.4 GHz. The performance of the filter depends on geometry and location and types of the MEMS switches. Optimization has bee

Design of multi-Valued Quaternary Based analog-To-digital Converter
Research Output | Dar Al-hikmah Library | IIUM Only

Problem statement: The design of multi-valued quaternary based Analog-to-Digital Converter (ADC) circuit was presented. The ADC generates multi-valued logic outputs rather than the conventional binary output system to overall reduction in circuit complexity and size. Approach: Design was implemented using pipeline ADC architecture and was simulated

Reconfigurable Patch Antenna by RF MEMS Switches
Research Output | Dar Al-hikmah Library | IIUM Only

A planar reconfigurable microstrip antenna is proposed by using RF MEMS switches. The proposed antenna structure comprises a center patch antenna known as driven patch and two adjacent microstrip patches defined as wing patches. Cantilever MEMS bridges are introduced to provide to operate antenna either 21.73 GHz or 23.6 GHz depending on the positi

Design of Reconfigurable Patch Antenna with a Switchable v-Slot
Research Output | Dar Al-hikmah Library | IIUM Only

In this paper we present the design of a novel Patch Antenna with Switchable V-Slot (PASVS) that resonates at two di®erent frequencies. The antenna operates at the lower frequency when the switch is OFF and at the higher frequency when the switch is ON. This antenna is designed for special applications which need small frequency ratio. The di®ere

Sewage Sludge as an Alternative Resource: Optimization of Media for Citric Acid Production
Research Output | Dar Al-hikmah Library | IIUM Only

Sewage is the largest contributor of organic pollution to water resources as well as to surrounding environments all over the world. In Malaysia, its contribution is top listed (64.4%), followed by animal husbandry wastes (32.6%), agro-based (1.7%) and industrial effluent (1.3%) in terms of the BOD load (Alam et al. 2009). Approximately 4.2 million

Keajaiban Sains Dalam Hadis (Terjemahan Al-"ijaz Al-'ilmi Fi al-Sunnah al-Nabawiyah)
Research Output | Dar Al-hikmah Library | IIUM Only

Di pasaran, kita boleh dapati dengan banyak sekali buku-buku yang menceritakan tentang "Keajaiban Sains Dalam Al-Quran". Namun amat jarang dan sukar kita temui buku-buku yang mendedahkan tentang "Keajaiban Sains Dalam Hadis." Kelahiran Rasulullah s.a.w yang membawa rahmat dan sinar cahaya ke seluruh alam bukan sahaja untuk mengeluar
