What causes resistance to flow? Flow resistance in rivers is caused by any feature of the channel topography, shape, or bed texture (grain size and grain-size distribution) that serves to slow the river flow. How is blood flow related to pressure and resistance? In the arterial system, as resistance increases, blood pressure increases and flow […]
Is hole a real particle?
Is hole a real particle? Holes are not actually particles, but rather quasiparticles; they are different from the positron, which is the antiparticle of the electron. Holes in a metal or semiconductor crystal lattice can move through the lattice as electrons can, and act similarly to positively-charged particles. Why conductors do not have holes? In […]

What is meant by dielectric loss?
What is meant by dielectric loss? Dielectric loss, loss of energy that goes into heating a dielectric material in a varying electric field. For example, a capacitor incorporated in an alternating-current circuit is alternately charged and discharged each half cycle. Dielectric losses depend on frequency and the dielectric material. How does dielectric loss occur? In […]
What is the best type of body scan?
What is the best type of body scan? A CT/CAT scan can be performed on every area of the body and provides greater clarity than traditional X-rays. “A CT scan is sort of our workhorse of radiology,” Dr. Herron said. Which is better MRI or ultrasound? MRI is also preferred for conditions that impact deep […]
