Enhancing Tool Life of Silicon Nitride Inserts via Hybrid Microwave Post Sintering
Research Output | Dar Al-hikmah Library | IIUM Only

Silicon nitride is in the group of hard covalent materials (Homlberg and Matthews, 1994) and often has amorphous structures with the atomic bonding which are formed with very high cohesive forces (Grzesik, 2008) that can withstand high temperatures, higher resistance to abrasive wear and improved oxidation and chemical resistance (Kalpakjian, 2013)

Improving Efficiency and Enhancing Productivity in Transporting Fertilizers by Using Conveyor Belt Cleaners
Research Output | Dar Al-hikmah Library | IIUM Only

Conveyor belts are used widely to carry and transport various materials ranging from fertilizers to foods items from the cargo ship to the packaging site. Spillage and carryback problems are common issues relating to transportaion of these types of materials at Malaysian ports. This leads to lots of wastage in fertilizers and food. In addition, ext

Electronic State Transition in Cooperatively Interacting point-Defects in Semiconductor Crystals
Research Output | Dar Al-hikmah Library | IIUM Only

Electron state transition of deep level point defects in a semiconductor crystal was studied. Low-temperature grown GaAs produced excess antisite As (AsGa) which produces localized spin when doped with Be. A nearly abrupt decrease of 1.7% of the resistance is detected at a temperature around 4 K which is consistent with abrupt decrease of magnetiza

Synergism Between Antibiotics and the Extract of Selected Prophetic Medicine Toward Different Types of Bacteria
Research Output | Dar Al-hikmah Library | IIUM Only

It is important to find new ways that are effective for the treatment of infectious diseases caused by drug-resistant bacteria such as the usage of plant extracts which have the antibacterial activity together with antibiotics which do provide synergistic effect. The objectives of this study are to evaluate synergism between different types of prop

α-mangostin Improves Glucose Uptake and Inhibits Adipocytes Differentiation in 3t3-l1 Cells
Research Output | Dar Al-hikmah Library | IIUM Only

α-Mangostin is a major compound found in mangosteen fruit hull and it has been reported to have wide range of pharmacological activities. The current study seeks to evaluate the in vitro activities of α-mangostin on adipocyte differentiation, glucose uptake and related gene expressions. The inhibitory effect of the compound on lipid accumulation

Bromelain: an Overview of Industrial Application and Purification Strategies
Research Output | Dar Al-hikmah Library | IIUM Only

Abstract This review highlights the use of bromelain in various applications with up-to-date literature on the purification of bromelain from pineapple fruit and waste such as peel, core, crown, and leaves. Bromelain, a cysteine protease, has been exploited commercially inmany applications in the food, beverage, tenderization, cosmetic, pharmaceuti

Third Sector socio-Economic Models: How Awaqf Fits In?
Research Output | Dar Al-hikmah Library | IIUM Only

In this paper, we investigate various theoretical frameworks of third sector (voluntary sector) economy with an aim to propose for a sustainable and inclusive socio-economic development model. An economic model that incorporates the third sector, together with the public and private sectors, is argued to be not only economically viable, but ethical

The Impact of Landscape Setting and Architectural Element on the Outdoor and Indoor Microclimate: a Case Study of Masjid al-Mukarramah, Bandar Sri Damansara
Research Output | Dar Al-hikmah Library | IIUM Only

Being in the tropical region, Malaysia experience relatively high air temperature and humidity throughout the year. People are trying to avoid the sun. Improper landscape design could contribute further in the increasing outdoor air temperature. This would further affect the indoor microclimate. Nowadays people are turning to the mechanical solutio

Effect of Lectin from Artocarpus Heterophyllus Seed on Cancer Cell Lines
Research Output | Dar Al-hikmah Library | IIUM Only

The objective of this paper to present cytotoxic effect of jacalin, a purified protein and crude protein from A.heterophyllus seed against cancer cell, human breast cancer (MCF7) and non-small lung carcinoma (H1299). The extraction and purification were carried out by phosphate buffer precipitation and reverse miceller, respectively. MTT and trypan

Carbon Dioxide Capture at Various Temperatures Using Ca(Oh)2 Sorbent Fabricated by sol-Gel Route in Ethanol Media
Research Output | Dar Al-hikmah Library | IIUM Only

Carbon dioxide (CO2) is considered to be the main greenhouse gas contributing to global warming and climate change. Therefore, the present paper investigates the CO2-capture performance of synthesized calcium hydroxides, Ca(OH)2 sorbent at different temperatures which are 350, 450, 550 and 650ºC. The CO2 adsorption of the materials synthesized was
