Abstract:
Nine strains of Vibrio parahaemolyticus from widely varied sources were exposed to heat in sterile clam homogenates. D-values were determined at temperatures ranging from 49 to 55 C for four strains, and at 51 C for the remaining five strains. The D-values in minutes, corrected for thermal lag and lethality during thermal lag, were 0.39 to 0.70 at 49 C. 0.26 to 0.54 at 51 C, 0.12 to 0.31 at 53 C, and 0.03 to 0.24 at 55 C. Values of z in degrees Centigrade determined for four strains were 5.6 to 12.4. One strain was found to be significantly more resistant at 53 and 55 C.

Thermal expansion and Thermal stress: Problem Solving
To solve the problem, first, identify the known and unknown quantities. The initial length (L) of the bridge is 1275 m, the coefficient of linear expansion (α) for steel is 12 x 10-6/°C, and the change in temperature (ΔT) is 55...
Homogeneous Equilibria for Gaseous Reactions
For gas-phase reactions, the equilibrium constant may be expressed in terms of either the molar concentrations (Kc) or partial pressures (Kp) of the reactants and products. A relation between these two K values may be simply derived from the ideal gas equation and the definition of molarity. According to the ideal gas equation:
Thermal Strain
Resistivity
Resistance
