Abstract- A new heating method for hyperthermia using microwave and ultrasound simultaneously is proposed‚ and temperature distributions are obtained by computer simulations. The results have shown that the simultaneous use of microwave and ultrasound can heat wider and deeper region than the sole use‚ and can reduce the input power of microwave and ultrasound. This implies that we can reduce the hazards that high power microwave and ultrasound may bring about. SUMMARY: In hyperthermia‚ tumors are

Calorimetry labs are frequently performed in order to determine the heat of reaction or the heat of fusion or the heat of dissolution or even the specific heat capacity of a metal. The calorimeter is a device used to measure the quantity of heat transferred to or from an object. The amount of heat needed to change the temperature depends on how much you want to change the heat. Specific heat capacity is different for all

Before beginning our research on radio waves‚ to us‚ radio waves were just waves going through the atmosphere‚ carrying sound from one place to another. Those were our ignorant days! We did not realize the complicated terms and theories involved. In the following report you will see how we advanced in our knowledge of radio waves‚ and we hope it will do the same for you. Radio waves are a combination of two kinds of electric vibrations. Audio frequency waves‚ which represent voice and other

Heat engine= device to turn heat energy into useful work: heat comes from something hot but only some goes to useful work. Satellites=free fall. Ionizing radiation=energy in the form of waves or paricle Beta radiation-just an electron‚ wont go through skin but really bad inside you alpha- he2+ nucleus-wont go through

What are the definitions of each type of heat transfer? 4. Is ice-cold bath the best cooling device to cool a soda? The goal of the project is to determine which type of cooling device will be effective in cooling a soda. In other words‚ the effect of cooling devices on soda cans. There will be four types of cooling devices used

1. Thermal inertia is a measure of the thermal mass and the velocity of the thermal wave which controls the surface temperature of a material. In heat transfer‚ a higher value of the volumetric heat capacity means a longer time for the system to reach equilibrium. 2. The ocean acts as a massive heat-retaining solar panel. 3. Salinity‚ temperature and depth all affect the density of seawater. 4. A pycnocline is the cline or layer where the density gradient (∂ρ⁄∂z) is greatest within a body of water

Radio Waves In the modern society‚ radio is the most widely used medium of broadcasting and electronic communication : it plays a major role in many areas such as public safety‚ industrial manufacturing‚ processing‚ agriculture‚ transportation‚ entertainment‚ national defense‚ space travel‚ overseas communication‚ news reporting and weather forecasting. In radio broadcasts‚ they use the radio waves which can be both microwaves and longer radio waves. These are transmitted in two ways: amplitude
