The partial pressure of ammonia in alveolar air was measured and found to be the same (within the limits of experimental error) as the calculated partial pressure of ammonia in arterial plasma. It is likely that ammonia is equilibrated between alveolar air and the blood during its passage through the pulmonary capillaries.
Linear multistep methods using higher derivatives are discussed. The order of damping at infinity which measures the stability behavior of a fc-step method for large h is introduced. ,4-stable methods with positive damping order are most suitable for stiff problems. A method for computing the damping order is given. Necessary and sufficient conditions for A… (More)
Linear multistep methods for the second order differential equation y" = 2 — X y, X real, are said to have an interval of periodicity if for a fixed X. and a stepsize sufficiently small the numerical solution neither explodes nor decays. We give a very simple necessary and sufficient condition under which a linear multistep method has an interval of… (More)
We propose a procedure to initialize the magnetic flux, possibly discontinuous, on a finite volume grid in an exactly solenoidal way. That is, a certain discrete divergence operator will vanish on each cell. Combined with a new locally divergence preserving numerical scheme we are able to conduct MHD simulations which have an exactly vanishing discrete… (More)
Boundary integral equation methods play a key role in computational electromagnetics. Here we discuss a special variant designed for the simulation of electromagnetic scattering at a non-smooth partly PEC coated dielectric object.
