The Photovoltaic (PV) system converts only a selected band (0.35μm to 0.82 μm) of solar radiation to electricity. The absorption of radiation outside this band leads to a temperature raise of PV module which affects its performance. Experiments were performed to prevent radiation outside the selected to reach the PV panel using water filtersand d

In recent years, wireless communication particularly in the front-end transceiver architecture has increased its functionality. This trend is continuously expanding and of particular is reconfigurable radio frequency (RF) front-end. A multi-band single chip architecture which consists of an array of switches and filters could simplify the complexit

This paper discusses the effect of propagation of electromagnetic waves through a cloud of very small particles. The size of these particles is normally less than 0.2 mm in radius, much smaller than the microwave wavelength; therefore it is possible to avoid laborious computation by using approximations. In this work we have checked the Rayleigh th

‘Islamic Economics Education in Southeast Asian Universities’ deliberates on an important, yet relatively neglected and under-written area in Islamic economics, i.e. Islamic economics education. In view of the importance of providing the necessary guidance in the integration and Islamization process in the discipline of economics, this book sta

Automatic adjustment rear view mirror system is designed to constitute for the weak points of the manual adjustment rear view mirror. This system determines the optimal position angle of the rear view mirror based on height of the driver, categorised as short, medium and tall. To achieve this target, the driver’s face coordinates are measured by

In Asia the tradition of using natural products for preservation and conservation of art works has been common along the history and still in practice. Malaysia being rich in natural resources the tradition of using local herbs, fruits and plants has been common among the craftsmen to preserve their cultural heritage. In this paper as the case stud

Desalination methods are used to convert saline/brackish water to drinkable freshwater. Major processes use either thermal energy (conventional distillation) or pressure energy (Reverse osmosis). Different methods of desalination are discussed and their influence on overall water production has been highlighted. With the increase in appreciation fo

A new widdrane sesquiterpene was isolated from Knema patentinervia by chromatographic methods. The structure was elucidated by spectroscopic methods, including 1H–1H COSY, HMQC, HMBC, and NOESY NMR experiments. The compound showed no inhibition of leukemia cancer cell growth and no inhibition towards bacterial growth of Staphylococcus aureus, Bac

The increasing incidence of obesity has opened the gap to search for the adipogenic differentiation-inhibitory compounds from natural products. This has raised our concern to evaluate the effects of Garcinia species which is well-known for its phytochemical contents such as flavonoids, phenolic acids and xanthones. Despite its highest medical prope
