Objective: To study the effect of both laser and ultrasound radiation on bone fracture healing process. Materials and Methods: Nd:YAG laser (1064 nm wavelength, 135 mW power, 16 joules energy) and ultrasound (1 MHz frequency, 50 mW/cm2 power intensity) were used in this work. Fifteen mature, male, albino rats, were divided into three groups and sub

Attenuation due to rainfall can severely degrade the FSO links operating under tropical weather. It restricts the distance of FSO communication systems and limits the availability for line-of-sight terrestrial link. Practical FSO link has been setup, monitored and analyzed. A commercially available FSO system was installed at 800 m length together

Femtocell network is a new technology that uses the advantage of an Internet backbone to enhance the cellular coverage in residential or small business areas. However, due to the expected random deployment of the femtocell access point (FAPs), there is a strong probability of interference among the femtocell nodes and between the femtocells and the

Identification of marine sand-dwelling species is important due to the toxin-producing abilities of some species that may harm human beings. In this study, sand samples were collected for 12 months at Dinawan Island, Sabah. Samples were identified using light microscopy (LM) and Scanning Electron Microscopy (SEM). Sixteen dinoflagellates species ha

A novel design is proposed for a I-Gbps Impulse Radio lJltra Wideband (IR-lJWB) pulse generator. The generated pulse is not just suitable for solving the problem of UWB interference with Wireless Local Area Network (WLAN) 802.11a and Worldwide Interoperability for Microwave Access (WiMAX) systems, but it has no interference on any narrowband system

Study on bioactive compounds in essential oil of Malaysian wild ginger species, Zingiber puberulum was carried out. The essential oil was extracted from the inflorescence of Z. puberulum using SFE at 48 Mpa and 40°C of extracting pressure and temperature respectively. The oil was then analysed using gas chromatography-mass spectrometry (GC-MS) ins

A new experimental porous glass ceramic coating for dental implants was prepared with a new formula consisted of a sintered glass ceramic based on alumina, silica glass and boron trioxide. The resultant sintered objects were anodized by one step anodization method at a constant potential of 40V and at a temperature of 22°C. X-ray diffraction analy

A novel design of 4-Gbps and 6-Gbps Impulse Radio Ultra Wide band (IR-UWB) pulse generator for short range wireless communication is presented. The simple structure of the proposed pulse generator helps to overcome the limitations of generating the two high speeds, the pulse generator based on two synchronized sources of 2GHz only. The pulse genera

Periodontitis is a chronic inflammatory disease, elicited by a complex mixture of anaerobic, Gram-negative bacteria that result in the destruction of the supporting structures of the dentition (Pihlstrom et al, 2005). This disease affects the majority of population (Brown et al, 1996) and the periodontal tooth mortality was reported by Ong, 1998 to

The development of Sukuk market as the alternative to the existing conventional bond market has risen the issue of rating the Sukuk issuance. These credit rating fulfil a key function of information transmission in capital market. Moreover, basel Committee for Banking Supervision has now instituted capital charges for credit risk based on credit ra
