diffusion-Reaction of Substrate in Immobilized Slab Biocatalyst for michaelis-Menten Kinetics
Research Output | Dar Al-hikmah Library | IIUM Only

The mass transfer effect on the overall reaction rate in a biocatalyst with a slab geometry containing an immobilized enzyme or cells has been investigated theoretically; Michaelis-Menten kinetics was studied. Numerical solution is used to solve the diffusion-reaction problem for Michaelis-Menten kinetics. The numerical scheme used was shooting met

Wastewater Treatment by Immobilised Cell Systems
Research Output | Dar Al-hikmah Library | IIUM Only

The immobilization of whole cells is an important technique which provides alternative solution in the field of wastewater treatment for the purification of wastewater contaminated with various materials, such as organic compounds, inorganic compounds, metals, and so on. The immobilized cells are biocatalysts which can easily be separated from trea

Aerobic Biodegradation of Oil and Grease in Palm Oil Mill Effluent Using Consortium of Microorganisms
Research Output | Dar Al-hikmah Library | IIUM Only

The current methods adapted for the treatment of Palm Oil Mill Effluent (POME) in most of the palm oil mills are not very effective in treating the pollutants in the POME to the stringent standards required. Furthermore the status and concentration of oil and grease after the treatment processes is given less attention and this suggests that these

Optimum Medium Components for Biosurfactant Production by Klebsiella Pneumoniae Wmf02 Utilizing Sludge Palm Oil as a Substrate
Research Output | Dar Al-hikmah Library | IIUM Only

In the present study, optimizing critical nutritional constituents was attempted as a primary strategy to improve biosurfactant production from Klebsiella pneumoniae WMF02 in liquid state fermentation utilizing sludge palm oil as a substrate. One-factor-at-a-time (OFAT) optimization was employed to evaluate the effects of sludge palm oil (SPO), suc

A New Geometrical Approach to Solve Inverse Kinematics of Hyper Redundant Robots with Variable Link Length
Research Output | Dar Al-hikmah Library | IIUM Only

In this paper a new approach that generates a general algorithm for n-link hyper-redundant robot is presented. This method uses repetitively the basic inverse kinematics solution of a 2- link robot on some virtual links,where the virtual links are defined following some geometric proposition. Thus, it eliminates the mathematical complexity in compu

لا يخفى على متتابع تطورات الوقف في عالم اليوم، من أن تطبيق عقود (BOT) أصبح على نطاق أوسع لدى تطوير الاقتصاد وشئونه ومتعلقه، وأعني بالذات من خلال إعادة إعمار البنية التحتية العامة، وسبب ذلك يعود إ

Nonproliferative and Proliferative Retinopathy
Research Output | Dar Al-hikmah Library | IIUM Only

Diabetic retinopathy falls into two main classes: non proliferative and proliferative. The word "proliferative" refers to whether or not there is neovascularization (abnormal blood vessel growth) in the retina. Non-proliferative diabetic retinopathy, previously called background retinopathy, is the earliest stage of diabetic eye d

This story as most detailed and fascinated about one of the companions of prophet Rasulullah (S.A.W) and his contribution and sacrifice tonards Islam. It is an edutainment that targeted audience

Comparative Study of Bioreactors Used for Palm Oil Mill Effluent Treatment Based on Chemical Oxygen Removal Efficiencies
Research Output | Dar Al-hikmah Library | IIUM Only

The conventional treatment method for palm oil mill effluents (POME) is predominantly anaerobic system, which involves the use of various bioreactors. Some of these bioreactors have been studied for the treatment of POME at laboratory scale, though few have been applied industrially. Such bioreactors include up-flow anaerobic sludge blanket (UASB)

Effect of Homogenization in Breaking protein-Carotenoid Complexes for Releasing Active Compounds
Research Output | Dar Al-hikmah Library | IIUM Only

The effect of homogenization in breaking protein-carotenoid complexes from cassava leaves was examined by monitoring three process conditions; amount of solvent per 0.5 g sample (ml), homogenization speed (rpm) and homogenization time (s). Acetone-n-hexane (1:1, v/v), tetrahydrofuran-methanol (1:1 v/v) and acetone were employed in the extraction pr
