This study was designed to determine antiproliferative properties of curcusone B from the stem bark of Jatropha curcas on cell lines K562 (chronic myelogeneous leukemia), and H1299 (human non-small cell lung carcinoma). Cells were cultured in the presence of curcusone B at various concentrations and the percentage of cell viability was evaluated by

Transducers are devices that transform energy from one form to another. Such transformation process may be applicable in the measurement of physical quantities, transfer of information and also in performing a certain control action. Transducers used as measuring devices are generally termed as sensors. Such transducers detect the changes in charac

This chapter investigates the effects of voltage supply interference on the performance of hybrid stepper motor. MATLAB Simulink is used to model the power supply, sinusoidal interfering signal, stepper motor driver circuit and the hybrid stepper motor. This stepper motor is using a DC Voltage supply of 28 volts and it is a two-phase motor with a s

Heterogeneous, {hetero + genos 'type', from Greek), is defined in Oxford Advanced Learner's Dictionary as "consisting of many different kinds of people or things" and defined in Longman Dictionary as "consisting of parts or members that are very different from each other." The design of interconnected nodes may be hetero

This paper reports a study on the perceptions of learning via online games among Arabic elementary language learners at the Centre for Foundation Studies (CFS), International Islamic University Malaysia (IIUM). The survey was a part of a front-end analysis for the design and development of an online Arabic vocabulary games prototype. It elicited le

The study of the gasification of a droplet via vaporization, which involves heat, mass and momentum transfer processes in gas and liquid phases, and their coupling at the droplet interface, is necessary for better understanding and modeling of complex spray and mixture formation issues. A detailed description of the vaporization of an isolated drop

The gasification of a droplet via vaporization is one of the main processes in combustion systems, namely diesel and propulsion engines. In these combustion systems, always the liquid fuel is atomized as a cloud of droplets in the chamber, which then vaporizes, and mixes with the oxidant and burns to release heat. Therefore, to afford a better know

This paper involves analysing and designing a prototyping system that automates the evaluation of land. The main objective of this study is to eliminate the needs to rate the suitability of land areas for several land use types (LUTs) manually. Tropical Crops Selection Advisory (TROPSEL) will be able to auto select LUTs according to known land char

This innovation features an online Arabic vocabulary learning games prototype spe-cifically designed for Arabic elementary learners at the pre-university level from Cen-tre for Foundation Studies (CFS), International Islamic University Malaysia (IIUM). This game-based learning prototype enables lecturers’ and students’ access to addi-tional Ara

Variations in the arterial pattern of the upper limbs are frequently observed. During ultrasonography with General Electric Ultrasound machine with 12L-RS linear probe on a 47-year old Malay man, superficial brachioulnar arteries (SBUA) were found bilaterally. While persistent median artery (PMA) was only found on the right forearm. Both SBUA origi
