โœฆ Synopsis

four kinds of particles are considered: (1) initial concentrate particles, (2) thermally decomposed particles, (3) burned particles, and (4) inert particles (mainly SiO2). Only one size fraction is assumed, and all transitions are assumed to be rapid and depend mainly on the local conditions. 1 In the gas phase, only one reaction is considered (-~S 2 -0 2 + SO9. = 0). Balance equations are written for four gas components (02, S 2, SO9., Ng.).

All together the developed model consisted of 18 partial differential equations, which were solved numerically with proper initial and boundary conditions.

The rate at which red blood cells fall in vitro is used as a common clinical test for a number of pathological conditions. But this test becomes unreliable when one finds flaws in the model under consideration and these doubts raise the issue of aggregation of the red blood cells in concentration wh
