Diffusion-reaction problem in a porous solid catalyst is important in the design and analysis of heterogeneous phase reactors and has been extensively studies. However, the effect of intraparticle convection on the substrate transport inside the solid has been scantly reported in the literature, though intraparticle convection plays significant rol

INTRODUCTION: COVID-19 pandemic has caused a major impact to global public health including one of the high risk groups which is the medical students. This study was intended to assess knowledge, attitudes and practices (KAP) towards COVID-19 among medical students in International Islamic University Malaysia (IIUM). MATERIAL AND METHOD: An online

Abstract Overall Equipment Utilisation (OEU) plays an important role as a benchmark for manufacturing companies to determine each machine's efficiency. Currently, there is no proper OEU measurement system in legacy machines and only relies on human observation. This project aims to develop a measurement of OEU system by using Optical Character

In this paper, experimental vibration analysis on Teflon, woven roving glass and carbon/epoxy composite squeeze film dampers have been carried out. Composite dampers, each consists of 30 layers, were fabricated by hand lay-up method. Different outer and inner diameters of all the fabricated dampers and lengths have been used. Effect of squeeze film

The skyrocketing prices of oil and food are matters of great concerns for consumers, producers, national and international bodies. This book addresses this aspect in five independent but related essays. The first two essays model the extent of volatility of oil and food price shocks. Third essay examines the cross country mean and volatility spillo

Porous alumina containing hydrothermal derived hydroxyapatite (HA) composite were successfully fabricated via protein foaming-consolidation method. Alumina and HA powders were mixed with yolk, starch and darvan 821 A at an adjusted mass ratio to make slurry. The slurries were cast into cylindrical shaped molds and then dried for foaming and consoli

Handwritten digits classification has many useful applications. This has prompted decades of research into algorithms to produce an effective system of classifying handwritten images into text. Image processing and feature extraction play a large role in this process. An intelligent system is one, which is taught, and one, which uses this learning

The design and development of a pressure sensor based typing biometrics authentication system (BAS) is discussed in this paper. The dynamic keystroke, represented by its time duration and force generates a waveform, which when concatenated results in a user’s typing pattern for the typed password. The design of the BAS is in two stages, whereby t

Sapium baccatum is usually used as a timber. Its medicinal values are not well known and very little research has been conducted concerning the plant. Consequently, this study was conducted to observe toxicity effects of hexane extract of stem bark of S. baccatum. The toxicity effects were assessed through observation of physiological changes of th

A rigid-flexible manipulator may be assigned tasks in a moving environment where the winds or vibrations affect the position and/or orientation of surface of operation. Consequently, losses of the contact and perhaps degradation of the performance may occur as references are changed. When the environment is moving, knowledge of the angle α between
