In first-order kinetic model, predominant mechanism is simple diffusion
More specifically, simple diffusion
occurs in these areas that are quite important because most of sensory receptors are attached to these regions which quickly respond to specific changes in the body fluids; mainly, changes occur in osmolality and glucose concentration.
When [R.sub.k] is very large (red circles, Figure 8(e)), (33) reduces to (30) of simple diffusion
. In this case, the reaction resistor [r.sub.k] in the transmission line model (Figure 8(a)) is open circuit.
J'ai ecrit un scenario simple que j'ai essaye de realiser du mieux que j'ai pu avec des moyens limites[beaucoup plus grand que], a retorque M.Barkat, fair-play et visiblement content de la reaction sans complaisance de son public, d'autant qu'a sa decharge, les conditions normales de projection n'etaient pas reunies, s'etant contente d'une simple diffusion

Liquids dispensed into microtiter plates are often assumed to have been mixed thoroughly through simple diffusion
, multiple aspirate and dispense cycles with a liquid handler, or after a cursory shaking of the plate.
The results revealed that lipophilic enhancers were more effective than lipophobic ones  and in simple diffusion
experiments, this is very difficult to reveal possible interactions and it could be irrational to try and do so.
Given the increasing precision of available geochronological data and the computationally undemanding nature of simple diffusion
models, there is now little reason not to progress beyond Dodson's 1973 TC formulation in the quest for determining cooling rates.
