Wireless local area networks (WLANs) are considered to be the fastest growing communication technology because of their low cost and high data rates. In this paper the effect of interference caused by Bluetooth devices and Microwave ovens on the performance of 802.11b WLANs is investigated. Results show that 802.11b WLAN are not affected severely while operating in the presence of a Bluetooth l...

The measurement of the microwave absorptivity of materials typically requires expensive and arcane equipment and methods. I show that, for moderately absorbing materials (loss tangent δ ' 0.005 or higher), useful measurements can be easily made using a thermometer and a normal domestic microwave oven: the heat absorbed for suitably designed sample size and geometry relates directly to the absor...

The purpose of the study was to compare two methods for destruction of biological material for selenium (Se) analysis: wet digestion by conductive heating in programmed digestion block and digestion in microwave oven. In both methods samples were prepared in a closed system using nitric acid. Selenium was analysed by electrothermal atomic absorption spectrometry. The results have shown that bot...

Metal Nanoparticles have attracted considerable attention because of their excellent electronic and optical properties. They have been used in many fields, such as displays, solar cells, touchscreens, sensors, and electromagnetic interference shielding [1]. However, for most of these applications, metal Nanoparticles with high electrical conductance are required. Compared with various other met...

STATEMENT OF PROBLEM The fabrication of zirconium dioxide (ZrO2) dental prosthetic substructures requires an extended sintering process (8 to 10 hours) in a conventional oven. Microwave sintering is a shorter process (2 hours) than conventional sintering. PURPOSE The purpose of this study was to compare the fracture toughness of 3 mol % Y2O3-stabilized ZrO2 sintered in a conventional or micro...
