Carbon nanotubes (CNTs) are interesting materials which are being researched intensively in the past few year. Application of CNTs in water treatment with their unique properties has attracted the attention of many scientists and engineers. Moreover, manipulation of CNTs with other polymers has been done for different applications. This study descr

Purpose – The main purpose of this paper is to investigate the acceptance level of Islamic accounting course by undergraduate students at the Universiti Malaysia Sabah (UMS). The study used theory of reasoned action (TRA) to analyze the findings. Design/methodology/approach – The primary data for the study are collected using self-administered

The design of a prototype monolithic Micro Electro-Mechanical Systems (MEMS) electronic circuits, namely the Voltage Controlled Oscillators (VCOs) is presented. The components can achieve the stringent requirements of wireless communication applications such as GSM cellular telephony. The VCO meets the low phase noise specifications of -136 dBc/Hz

Modeling and design of a single photon detector and its various characteristics are presented. It is a type of avalanche photo diode (APD) designed to suit the requirements of a Quantum Key Distribution (QKD) detection system. The device is modeled to operate in a gated mode at liquid nitrogen temperature for minimum noise and maximum gain. Differe

The Performance of Orthogonal Frequency Division Multiplexing (OFDM) combined with Quadrature Amplitude Modulation (QAM) has been analyzed in presence of fiber optic dispersion. The influence of dispersion on the (OFDM) spectrum is investigated with fiber lengths, bit rates, no. of channels and source line widths. The inter-channel interference occ

Many configurations of EDFA producing triple pass EDFAs have been used, however, only two configurations are commonly used in the optical fiber communication system due to their high performance. Those two configurations are configured in a double stage EDFA. The first configuration is (configuration A) consists of a single-pass EDFA as the first s

As the main statute on consumer protection in Malaysia, the Consumer Protection Act 1999 deals with various aspects of consumer protection including a supply of goods. The CPA not only provides a new set of guarantees which are implied in every contract of supply of goods to consumers but also introduces a different remedial scheme in cases of brea

In this work, various activated carbons have been prepared by steam activation from oil palm empty fruit bunches to study the effect of activation temperature, activation time and steam flow rate. Series of batch laboratory experiments were conducted in order to investigate the feasibility of activated carbon – derived from oil palm empty fruit b

Security is the most tedious problem in highly sensitive communications. Quantum security is the key issue in solving the problem. A key distribution protocol based on the use of hash functions is proposed. The essential part of the protocol depends on sending a string of random characters from sender to receiver. Then, a selected hash or a cascade

This research reports the study that aims to enhance the activity of xanthine oxidase inhibitor, a secondary metabolite, found in Chrysanthemum indicum and to identify the most suitable elicitors with the optimize elicitation time and concentration. Many plant species are well known source of secondary metabolite with a variety of biological activi
