We investigated the analgesic effects of escalating doses (0.214, 0.286, 0.357, and 0.429 mg/kg) of oral morphine on tolerance to painful cold pressor in a double-blind, active placebo-controlled (diphenhydramine) study in 45 normal volunteers. The highest dose of morphine administered is equivalent to the starting dose recommended by the Agency for Health(More)
Figure 2.1. A 1-D example of the discontinuous thermal conductivity across the interface (Left) and the corresponding temperature profiles (Right). Figure 2.7. The illustration above shows the ghost nodes for the vapor phase (black nodes) and the liquid phase (gray nodes), which are used to calculate the temperature gradient in the other respective phase..(More)
A new method is presented for modeling contact surfaces in Lagrangian cell-centered hydrodynamics (CCH). The contact method solves a multi-directional Riemann-like problem at each penetrating or touching node along the contact surface. The velocity of a penetrating or touching node and the corresponding forces are explicitly calculated using the(More)
