Knowledge of the performance of cutting fluids in machining process is important in order to improve the efficiency of any machining process. The objective of this work is to compare the performance of CPO to commercially available cutting fluid which is Solkut 2140 cutting fluid in terms of cutting forces, surface roughness of the workpiece and tool wear in turning process by using coated carbide insert as cutting tool and AISI 304 austenitic stainless steel as workpiece material. In general, the results indicated that CPO performed better than Solkut 2140 in reducing the cutting forces, improving the surface finish and reducing the tool wear. CPO has been used as a cutting fluid in this work because it provides the desirable quality for boundary lubrication, biodegradable, less toxic and vast resources.

Deposition of complex and heavy organic compounds, which exist in petroleum crude and heavy oil, can cause a number of severe problems. In present study wax deposition was studied at 80°C using cold finger device. Three crude oil samples were tested in original and demetalized composition for wax deposition. FTIR and GC-MS was used for chemical composition and structural analysis of the obtained wax. Significant difference was observed for wax deposition in original and demetalized crude oil samples. The chemical composition analysis of carbon-hydrogen stretching mode showed a strong absorption between 2850 cm•1, 2916 cm•1 and 2950 cm•1. GC-MS analysis confirmed the pattern of n alkanes with presence of other high molecular weight compounds in wax obtained from crude oil samples.

This paper presents the preliminary findings of on going study intended to develop a cool house by introducing roofing materials with higher Solar Reflectance Index (SRI). SRI is a composed measure that accounts for surface's solar reflectance and emittance. It is measured on a unitless scale from 0 to 1. Residential buildings in Malaysia are experiencing overheating of roof space due to inappropriate selection of roofing systems and materials. This badly affects the indoor thermal comfort of low rise buildings where roof represents 70% of heat gain. Emissions from building sectors are about 8.6Gt of CO2 per year. The thermal performance of a building is affected by the solar absorbance of roof. During a clear sky conditions up to 1kW/m2 of radiation can be incidental on a roof surface and between 20% and 90% of this radiation is typically absorbed. This study emphasizes on observation and documentation of main parameters which influence SRI of roof tiles i.e. (1) Roof color, (2) material composition, and (3) the degree of roof slope. The research methodology consists of (1) construction of one unit experimental house to study the effects of SRI of roof on indoor thermal comfort, and (2) semi-structured questionnaire survey conducted to determine the roof colors on existing buildings in Malaysia. Home buyer's roof color preference was also determined. The research outcomes will have important implication for application of cool roofs and sustainable development in Malaysia.

Cu-WC-Si composites were synthesized by using a planetary ball milling. Different composition of elemental Cu, WC and Ti powders were mixed and milled for 5 and 10 hours in an open air. The powder characterized before and after milling to expose the effect of milling variables on particle size, homogenization and contamination. Analyzing carried out by using X-ray and scanning electron microscope (SEM). The as milled particle size and homogenization generally influenced by milling time and tungsten Carbide (WC) content. With longer milling time and higher tungsten carbide content, particle size becomes smaller and smaller. The average particle sizes of the as milled powder are in ranged from 5µm to 30 µm and strongly depend on the copper content.

The heating of crude oil by using electromagnetic waves can enhanced the recovery of crude oil due to reduction in its viscosity and assisting in its movement. This paper describes effect of electromagnetic waves on oil recovery by using curve twin dipole antenna with four magnetic feeders in the radio frequency region. Two similar core rock samples were use in this study. The porosity and permeability of the core samples were measured by using Poroperm System. Oil saturated core rock samples were kept in tank filled with brine of 10000ppm salinity for efficient oil recovery. These core rock samples were kept at room temperature and 55°C with and without electromagnetic waves. The EM waves emitted by the curve twin antenna with 4 magnetic feeders were able to recover 10.60% of OOIP at room temperature and 29.28% of OOIP at 55°C. Core rock samples without electromagnetic waves give oil recoveries 7.66% of OOIP at room temperature and 23.15% of OOIP at 55°C.

Jatropha oil has been known as alternative substitute for diesel fuel but its potential use as lubricant is not much known yet. Esterified jatropha oil has been successfully synthesized through esterification process to be used as lubricant additives. This study is meant to investigate wear preventive characteristics of esterified jatropha oil as potential renewable lubricant additives. The characteristics were obtained using four ball test configuration. Addition of low percentage esterified jatropha oil to mineral oil is found to have good effect in reducing wear.

Testing of digital systems has been widely researched and studied. Many test methods have been developed and used. However, traditional voltage and current testing are not sufficient in modern integrated circuit (IC) design. This paper introduces a new method using electromagnetic field (EMF) generated from a circuit, which can be used to detect and diagnose possible faults in millimeter scale circuit. CST Microwave Studio and SONNET EM simulator are used to simulate detection of magnetic field intensity above several microstrip lines which are shorted and opened. Furthermore, the models have been fabricated on FR4 and measured the transmission coefficients by Network Analyzer. Both simulation and measurement show that faults in circuits result in high Standing wave for both short and open cases. Open line tends to induce higher Standing Wave (SW) than short line.

Chemical flooding, in particular ASP flooding is of increasing interest because of current high prices and the need to increase oil production. Recent lab research has shown significant benefits to using surfactants at high PH even if the oil has a low acid no. & thus little if any surfactant is generated in-situ. So high ph surfactant-polymer flooding is also of great current interest. Normally, the problem in water flooding is unfavorable Mobility Ratio and because of it viscous fingering may occur and as a result of viscous fingering early break through will be observed, so low oil recovery will be obtained. The viscosity and the size of the emulsion formed in the reservoir is of great importance because if the size is too large and viscosity is high it can plug the pore spaces thus reducing the overall recovery and if the size is too small and viscosity is very low than the desirable sweep efficiency will not be achieved thus again causing reduction in recovery.

Our healthcare system nowadays is far more advanced from what we are twenty years ago. Adding to that, healthcare system is moving towards computerization and informative era. At this moment, implementation of Knowledge Management (KM) within healthcare system is very popular and motivating subject to focus. This paper listed and discussed two challenges faced by the Malaysian healthcare system, followed with the state of the art of the combination of KM and IT within healthcare system. The main KM mechanism focused in this paper is knowledge integration and knowledge sharing. We believe the successful of knowledge integration lead to opening the door to knowledge sharing. As the result, we suggested a theoretical framework for healthcare portal in Malaysia to encourage knowledge sharing using a case study scenario.

Biomass steam gasification with in-situ carbon dioxide capture using CaO exhibits good prospects for the production of hydrogen rich gas. The present work focused on the determination of reaction rate kinetics for hydrogen production from oil palm waste steam gasification using optimization approach in MATLAB. The kinetics parameters were calculated by fitting experimental data to kinetics model and minimization of least squared error between the model predictions and experimental results. The model was validated and showed good agreement with the literature. The developed model was used to investigate the effect of temperature and steam/biomass ratio on the product gas composition. Based on the results, hydrogen purity of more than 70 mol% can be achieved. It was found that increment in temperature and steam/biomass ratio is in favor of hydrogen production. The study provided a useful optimization approach for the determination of kinetics parameters for a specific biomass in future experimental work.
