This research demonstrated the use of conventional milling machines with diamond coated tools, high speed attachments, and air blowing mechanisms for ductile mode machining of silicon and subsequently modeling and optimizing the resultant surface roughness. Spindle speed, depth of cut, and feed rate, ranges: 60,000 to 80,000 rpm, 10 to 20 μm, and

The presentation aims to inform businesses of various consumer protection laws in Malaysia, in particular the laws under the jurisdiction of the Ministry of Domestic Trade,Cooperatives and Consumerism. It specifically focusses on understanding business’ obligations under the Consumer Protection Act 1999. It also highlights the recent amendment an

Machining of silicon is an expensive affair because its inherent brittleness leads to subsurface crack generation. Research endeavours have therefore focused on ductile mode machining of silicon to obtain crack free machined surfaces with roughness as low as 0.22 μm or even below, hence eliminating the need for subsequent polishing/grinding operat

Platinum, gold and palladium are precious metals which are widely used in industries for catalysts preparation, electronic components, electroplating, etc. Recovery of these trace metals in low concentration from solutions, plating bath, industrial effluents, etc. are essential for economic reasons and pollution prevention. One option is to use a s

This paper presents the development of an emissions-controlling technique for oil burners aimed especially to reduce oxides of nitrogen (NOx). Another emission of interest is carbon monoxide (CO). In this research, a liquid fuel burner is used. In the first part, five different radial air swirler blade angles, 30°, 40°, 45°, 50°, and 60°, resp

This paper presents a novel generic weak classifier for object detection called “Square Patch Feature”. The speed and overall performance of a detector utilising Square Patch features in comparison to other weak classifiers shows improvement. Each weak classifier is based on the difference between two or four fixed size square patches in an ima

Plants of the Rutaceae family are sources of active alkaloids with high potential to defeat microbial infectious diseases and overcome microbial resistance towards antibiotic. The anthranilic acid derived alkaloid especially quinoline, furoquinoline, acridone and 4-quinolone alkaloids are the common types of antimicrobial active alkaloids found in

Entada spiralis Ridl. which is locally known as Sintok or Beluru is a woody climber with a characteristic spiral stem. The stem bark is traditionally used as natural shampoo and body wash among Malays due to its high content of saponins and its medicinal properties. The methanol extract of the stem bark possess promising antimicrobial activity agai

Unlike research on environmental variables, interpersonal relationships, personal characteristics, and organizational factors, all of which have been empirically supported as the common sources of employee stress, evidence on the effects of commuting on their well-being is relatively scarce. The purpose of this study was to investigate the relation

The purpose of this paper is to make a contribution to the performance measurement system (PMS) literature by concentrating on the service context. Providing a Malaysian perspective on PMS design, the study aims to identify the desirable PMS attributes that are perceived to be important for the service sector. Data were collected by administering a
