Degree of covering

The various orientations of the crystallites of a metal specimen show up clearly, and it can be shown that the electron emission depends on the degree of covering with adsorbed atoms, which itself depends on orientation and on temperature (285-287). 

In order to have a visualization of the degree of covering of the e B function in terms of the relative error committed when developii the proposed approach, Figure 5.1 shows the error between values and a linear combination Ljq, defined using equation (5.2), after complete linear and non-linear parameter optimization. 

Where consultants are involved in providing contracting services as well as consulting services, they must ensure that they have an adequate degree of insurance to cover both aspects of their work. Although not common, it is possible to obtain tailor-made policies that encompass the indemnification provisions of both a professional indemnity policy and a public liability policy providing the necessary degree of cover for pollution related claims. 

For extrnded products, frequent monitoring of the extmsion process is reqnired to adjust settings for the greatest product uniformity. The most important factors to control are moisture in the tempered raw materials, feed rate, temperatures/pressure in the different zones of the extruder and die, the extmdate expansion rate, and moisture. It is also important to monitor the degree of covering that usually correlates with the sugar content (Stauffer 1990). 

Gives an indication of degree of covering. The sodium content should be declared in the food label.

The measurement of heat of adsorption is of great interest. It can be carried out either directly by calorimetry or indirectly from the isotherms obtained at various temperatures. It is noted in experiments that the heat of adsorption varies frequently with the degree of covering [GER 59, p. 59] (Figure 6.2). The values given by the tables are thus in general initial heats of adsorption (with null covering). 

At the adsorption equilibrium, the degree of covering is 0, and equation [6.1] becomes ... 

In this type of adsorption, the saturation given by the presence of certain structure elements on the surface can be limited to a small degree of covering, even without the intervention of steric hindrance. 

We can write the reactivities of the elementary reactions by using relation [7.15], with 0 indicating the degree of covering of adsorbed oxygen, the equilibrium constant of reaction i and P the pressure of oxygen. In our case there are three steps, which are written as ...
