Available information on the composition and methods of production for particulate reinforced metal matrix composites (PRMMCs) for wear resistant applications is reviewed. In general, PRMMCs exhibit better wear resistance compared to its unreinforced counterparts. Nevertheless, under specified conditions, the wear performance of PRMMCs is similar t

Enhanced weld cooling via forced convection using cryogenic cooling technique is an option for controlling grain growth in the HAZ of ferritic stainless steel and hence improves weld ductility. However, this technique probably alters the martensite distribution in the high-temperature heat affected zone (HTHAZ) which is a critical constituent in an

Other than grain coarsening, the loss of corrosion resistance in ferritic stainless steel (FSS) welds due to intergranular precipitation of chromium carbides restricts the use of the alloy for structural application. The use of cryogenic cooling offers dual opportunities for the control of weld geometry and grain structure in FSS. This results in i

The paper proposes first to study the behavior of honeycomb alone under uniform cyclic compression-relaxation loading. It is found that the behavior is linear until it reaches the maximum force following by a sudden drop of force and at the end following by a constant force during the compression. This force-displacement behavior is observed to be

This paper includes the performance of a solar assisted heat pump desalination system. Renewable, solar and ambient, energy and waste heat from air conditioning system are used for the production of fresh water. The experiment was conducted under meteorological conditions of Singapore (1o21’N; 103o55’E). The coefficient of performance (COP) for

An experimental campaign on metallic-palm fiber-metallic hybrid subjected to impact loading using spherical projectile has been carried out. High initial energy impact with projectile mass of 24 kg and speed of 1, 3 and 5 mm/s, has been set enabling to determine the energy absorption capability of hybrid composite panel. The influence of stacking s

Solid polymer electrolytes comprised of various weight percent ratios of poly(ethyl methacrylate) (PEMA) and lithium perchlorate (LiClO4) salt were prepared via solution casting technique using N,N-dimethylformamide (DMF) as the solvent. The conductivity values of the electrolytes were determined via impedance spectroscopy. The conductivity of the

Purpose – Islamic banking and finance is an emerging global industry founded on Islamic ethical precepts. Just as in the case of conventional banks, Islamic banks are expected to offer products that consider the needs of their customers. The present study investigates the effects of the following factors: attitude; social influence; religious obl

Despite considerable research in advanced countries on public perceptions of and attitudes to modern biotechnology, limited effort has been geared towards developing a structural model of public attitudes to modern biotechnology. The purpose of this paper is to identify the relevant factors influencing public attitudes towards genetically modified

Earlier studies on public attitude and risk perception have concluded that the public’s attitudes towards biotechnology was primarily driven by several factors such as familiarity, perceived benefits, perceived risks, risk acceptance, moral concerns and encouragement. Demographic characteristics have been known to affect attitudes towards science
