The mechanisms of CH4 transport commonly found in plants are simple molecular diffusion (differential partial pressures between the sediment, plant, and atmosphere), convective throughflow ventilation (via lacunal pressurization), and effusion (partial pressures differences in pore of plant). 

Now let turn to an examination of the obtained calorimetric data presented in Figs. 3-6 and in sequence to analyze the changes of differential partial molar enthalpy depending on hydrogen concentration in the IMC and experimental temperature.

Examples 4.2 and 4.3 and the models from Section 4.4 show that the stochastic models can frequently be described mathematically by an assembly of differential partial equations.

The basis for any numerical reactor performance simulation is a mathematical model, consisting of a set of ordinary differential-, partial differential-or integro-differential equations and initial and boundary conditions. An optimized solution method must then be designed for this particular set of equations. 

Ceramic electrochemical reactors are currently undergoing intense investigation, the aim being not only to generate electricity but also to produce chemicals. Typically, ceramic dense membranes are either pure ionic (solid electrolyte SE) conductors or mixed ionic-electronic conductors (MIECs). In this chapter we review the developments of cells that involve a dense solid electrolyte (oxide-ion or proton conductor), where the electrical transfer of matter requires an external circuitry. When a dense ceramic membrane exhibits a mixed ionic-electronic conduction, the driving force for mass transport is a differential partial pressure applied across the membrane (this point is not considered in this chapter, although relevant information is available in specific reviews). 

Thus, when y has been differentiated partially with respect to each c, in turn, i = 1, 2,..., r,..., n, a set of n homogeneous equations is obtained which are called the secular equations of the system. They are of the general form ... 

The mass transfer in the adsorption column can be deseribed by a set of differential partial equations, but the analytical solution is often difficult to establish. The adsorption parameters can also directly be obtained by the determination of the moments of the beakthrough curve. The fisrt moment, fi, is only related to equilibrium parameters, while the second moment, is related to mass transfer parameters [11], and they can be directly calculated by integration of the response curve. 

Volatile solvents (e.g., benzene, carbon tetrachloride) are excreted via the lung based on differential partial pressures between the capillary blood and the ah lar air. 

Deterministic models. Analogous to fluid mixing, the deterministic mathematical models of solids mixing are derived from the continuity (mass conservation) of a key component being mixed in a certain volume element in the mixer. If this volume element is finite in size, a lumped model is obtained, and if it is infinitesimally small, a continuous model. Under steady-state conditions prevailing in a continuous mixer, the lumped model manifests itself as a set of difference equations, and the eontinuous model, a set of ordinary differential equations naturally, a combined or hybrid model is expressed in the form of a set of differential-difference equations. The corresponding mathematical expressions under unsteady-state conditions prevailing in a batch mixer are sets of ordinary differential equations, partial differential equations, and ordinary differential-partial differential equations. 

Oxygen Permeance (P 02) may be defined as the ratio of the oxygen transmission rate to the differential partial pressure of oxygen on the two sides of the film. Oxygen Permeabihty Coefficient (PO2) is the product of the permeance and the thickness of the him as shown by Eqn (8.19).
