Although e-commerce is growing at a significant rate, a number of stumbling blocks continue to hamper its development. One stumbling block relates to formation of e-contract. There remains uncertainty whether the traditional principles of contract law can be adapted to the needs of electronic contracting. Consequently parties might disagree as to w

Besides the problem of low ductility and poor notch toughness of ferritic stainless steel welds due to the microstructure characteristics of the weld section as a result of the weld heat input rate and the heat transfer factor, susceptibility to intergranular corrosion caused by the depletion of the chromium content of the weld matrix particularly

The inclusion of provisions relating to a supply of services in the Consumer protection Act 1999 (the CPA) is very significant in the development of the law of services which previously has been left behind compared to the law on sale of goods. With the main aim of protecting consumers against sub-standard, defective or ineffective services, the CP

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
