Lattice Models with Interactions on Caylay Tree
Research Output | Dar Al-hikmah Library | IIUM Only

We consider an Ising competitive model defined over a triangular Husimi tree where loops, responsible for an explicit frustration, are even allowed. We first analyze the phase diagram of the model with fixed couplings in which a “gas of noninteracting dimmers (or spin liquid) — ferro or antiferromagnetic ordered state” zero temperature transi

Applying Computational Materials Design (Cmd) Toward Efficient Hydrogen Production from Water
Research Output | Dar Al-hikmah Library | IIUM Only

Hydrogen is probably the most promising solution to our global energy problems for the future. However, in order to support the developing hydrogen economy, efficient processes for hydrogen production and storage become necessary. Now a days, the hydrogen production is a large and growing industry. Globally, some 50 million metric tons of hydrogen

Understanding Terrorism: Contested Concept, Conflicting Perspectives and Shattering Consequences
Research Output | Dar Al-hikmah Library | IIUM Only

Terrorism is an old phenomenon but its modern manifestation was first noted in the 19th century with the anarchist group who assassinated Czar Alexander II in 1881. Since then it has continued unabated but its intensity and frequency increased in the 21st century. This study examines the trends in international terrorism and, in particular, analyse

problem-Based Learning as Viewed by Medical Students in a non-Problem Based Medical Curriculum
Research Output | Dar Al-hikmah Library | IIUM Only

The Medical Faculty of the International Islamic University Malaysia runs an undergraduate medical programme which implements a combination of traditional and new medical curricular trends. Problem based learning (PBL) is one of the teaching-learning approaches used in the preclinical years. This study analyses the effectiveness of PBL from the pre

Optimization of Cnts Production Using Full Factorial Design and its Advanced Application in Protein Purification
Research Output | Dar Al-hikmah Library | IIUM Only

Carbon nanotubes (CNTs) have been successfully synthesized by using in-house fabricated Double Stage Chemical Vapor Deposition (DS-CVD) technique, using acetylene (C2H2) and hydrogen (H2) as the precursor gases. The purity, morphology and the structure of CNTs were then characterized using Field Emission Scanning Microscope (FESEM), Transmission El

On Dynamical Systems and Phase Transitions for Q + 1-state p-Adic Potts Model on the Cayley Tree
Research Output | Dar Al-hikmah Library | IIUM Only

In the present paper we are going to investigate phase transition phenomena from the dynamical system point of view. Using the derived recursive relations we define one dimensional fractional p-adic dynamical system. We establish that if q is divisible by p, then such a dynamical system has two repelling and one attractive fixed points, in this cas

Intellectual Property Rights in the Light of Islamic Law and man-Made Regulations
Research Output | Dar Al-hikmah Library | IIUM Only

Intellectual property means the publication that is protected and remains as an exclusive right of its author. It is divided into two types. The first kind is auditory such as: sermons and lectures and its alike that are delivered orally. Customarily the right of this type of intellectual property belongs to all Muslims without any restriction. The

in-Utero Effects of the Crude Ethanolic Extract of the Leaves of Mitragyna Speciosa on Neural Tube Formation in Rats
Research Output | Dar Al-hikmah Library | IIUM Only

The developmental effects of in-utero administration of the crude ethanolic extract of the leaves of itragyna speciosa (MS) on neural tube in fetal rats were investigated. Pregnant Sprague-Dawley rats were dosed orally once daily by gavage, with graded (500, 1000 and 1500 mg/kg) doses of the extract between the 8th and 13th day prenatally. The cont

On Marginal Markov Processes of Quantum Quadratic Stochastic Prosses
Research Output | Dar Al-hikmah Library | IIUM Only

In this paper quantum quadratic stochastic process (q.q.s.p.) on von Meumann algebra M is considered. It is de¯ned two marginal Markov processes on von Neumann algebras M and MM, respectively, to given q.q.s.o. We prove that such marginal processes uniquely determine the q.q.s.p. Moreover, certain ergodic relations between marginal processes and

On the Description of Bistochastic Kadison–schwarz Operators on M2(C)
Research Output | Dar Al-hikmah Library | IIUM Only

In this paper we describe bistochastic Kadison-Schawrz operators on M2(C). Such description allows us to ¯nd positive, but not Kadison-Schwarz operators. Moreover, by means of this characterization we can construct Kadison{Schawrz operators which are not completely positiveOpen Systems & Information Dynamics Vol. 17, No. 3 (2010) 245{253 DOI:
