flows past objects have been studied extensively because of their many practical applications. For example, airfoils are made into streamline shapes in order to increase the lifts, and at the same time, reducing the aerodynamic drags exert...
history of Cardiovascular Sonography. Discussion The word ultrasound refers to sound waves beyond the range of human hearing (oscillations above 20,000 cycles per second or 20kHz). The dog whistle is an often-used example. Both sound and ul...
quantum mechanical signal functions describing matter. The occurrence of quantum mechanical interference of distinct neutrino states, neutrino oscillations, has provided one of the most stimulating developments in high energy element physic...
propagation. Parameters of an ultrasound wave include frequency, pressure, wavelength, velocity, power, and intensity. The last two are measures of the “strength” of the wave. Ultrasound is attenuated as it travels through the body due to b...
circuits it is essential to measure very small values of resistances. To measure very low values of resistances (resistances of m ohms) we should develop a circuit which can works under small amount of currents. Here i took micro ohm meter ...
physical region at (sin2 2_;_m 2) = (1:35; 2:0_10??3eV2) and _=1.02. On the other hand, if we bound the oscillation parameters in the physical region, _ 2 min(=12.8) takes place at (sin2 2_;_m 2) = (1:00; 3:2 _ 10??3eV2) and _=1.00. For the...
physical work setting of a company and safety and health issues related to the work setting. Physical Work Setting and Employee Health Some of the factors associated with the physical setting are mentioned as follows. Thermo hygrometer Cond...
