RADIOGRAPHIC DENSITY VS. ANATOMIC DENSITY ?
RADIOGRAPHIC DENSITY VS. ANATOMIC DENSITY ?
Homework Answers
Radiographic Density - the overall amount / degree of darkening
on a radiograph. In
routine radiography, the useful range of density varies from 0.3 to
2.0 density. The
density below 0.3 is due to the density produced by the base and by
some fog on the
film (base plus fog). Density is primarily determined by mA.
Atomic density means the number of atoms per unit volume. The atomic number of an element represents the number of protons in the nucleus and the number of electrons surrounding it.

(i) Plot the current density vs. overvoltage (j vs. h) relationship – the Butler-Volmer equation – for this reaction in the range h = -0.5 to 0.5 V. Assume a transfer coefficient a = 0.5 and vary the exchange current density: j0 = 10-3, 10-6, 10-9 A/cm2. Define the sign conventions for current and overvoltage. (ii) Plot the j vs. h relationship for j0 = 10-6 A/cm2 and a = 0.25, 0.5 and 0.75. (iii) Plot log½j½ vs. h curves...

After a normal exhalation, some air is left in the "anatomic dead spaces" of the lungs and airways. This air cannot be used to oxygenate capillary blood, because it never comes in contact with the capillary network. Which of the following respiratory structures CANNOT be an "anatomic dead space"?

cheerleader is complaining of pain over the right anatomic snuffbox. You determine that the cheerleader fell on an outstretched hand while performing a back flip at practice the previous day. Observation reveals minor swelling but no discoloration or deformity. Palpation reveals sharp pain in the anatomic snuffbox. What injury should you suspect? Explain what steps you would take in managing and treating her injury?
