Is 155-dB ultrasound in the range of intensities used for deep heating? Calculate the intensity of...
Deep ultrasonic heating is used to promote healing of torn tendons. It is produced by applying ultrasonic sound over the affected area of the body. The sound transducer (generator) is circular with a radius of 1.47 cm, and it produces a sound intensity of 6.22 x 103 W/m2. How much time is required for the transducer to emit 5710 J of sound energy? Number Units the tolerance is +/-2%
Radio waves and microwaves are used in therapy to provide "deep heating" of tissue because the waves penetrate beneath the surface of the body and deposit energy. We define the penetration depth as the depth at which the wave intensity has decreased to 37% of its value at the surface. The penetration depth is 15 cm for27 MHz radio waves. For radio frequencies such as this, the penetration depth is proportional to λ−−√, the square root of the wavelength. What...
Calculate SNR(dB) given a noise voltage specification of 500.5nV/sqrt(Hz), used over an audio frequency range of 20Hz to 20kHz, with a voltage gain of 55dB. The output voltage is 1.75 V. Calculate the noise voltage specification given SNR(dB) = 150dB using the same output voltage, frequency range, and gain as in number 3.
dB (decibel) is a unit used to measure sound intensity and is graphically plotted using the linear scale? TRUE OR FALSE
0 14.P010. is 158 dB a) Calculate the intensity of the sound wave generated by the jet at the given location. W/m2
The process mass intensity (PMI) allows chemists to calculate how much material is used when generating a target amount of product in a chemical reaction. PMI is expressed as follows: PMI = [(mass of all input materials) / (mass of desired product)] To synthesize moclobemide, an anti-depressant pharmaceutical, 0.00381 moles of 4-(2-aminoethyl)morpholine (C6H14N2O) is dissolved in 20.0 mL of triethylamine (density: 0.726 g mL–1) and 0.00384 moles of 4-chlorobenzoyl chloride (C7H4Cl2O) is added. After rapid stirring for 30 minutes, 10.0...
1. Focusing on only the inpatient care cost (i.e., ignoring operating room costs), what is the cost of a TAH (non-oncology) under each of the cost accounting systems? A tuboplasty? A TAH (oncology)? What accounts for the differences? Croswell University Hospital This report doesn't describe where our costs are generated. We're applying one standard to all patients, regardless of their level of care. What incentive is there to identify and account for the costs of each type of procedure? Unless...
