A volume licensing key (VLK), however, can be used on several computers. Vendors can take additional steps to ensure that their products' key are only used in the intended number. These efforts are called product activation .

Feb 24, 2014 · The volume of @A00093@ is interpreted, according to @T06470@, as the difference between the partial molar volumes of the @T06468@ (\(V\)) and the sums of the partial volumes of the reactants at the same temperature and pressure, i.e. \[\Delta ^{\ddagger}V = ^{\ddagger}V- \sum \left(r\ V_{\text{R}}\right)\] where \(r\) is the order in the ...
Oct 11, 2021 · In contrast, the following two types of application-relevant chemical reactions are driven almost entirely by shear: (i) material synthesis leading to growth of deposits or films on surfaces, and (ii) material removal from surfaces resulting in wear or polishing.

Oct 5, 2018 · 1. Introduction. Bulk metallic glasses (BMG) have no long-range order due to their amorphous structure, but it has been shown numerously that their short-range order is of great importance. By changing the short-range order and therefore the state of the metallic glass, intrinsic properties such as hardness or toughness can be changed [ 1, 2 ].

Mar 14, 2022 · The effect of pressure on the rate of a chemical reaction is measured by the activation volume (or volume of activation) . 5 - 18 The activation volume is the volume change of a reaction system from the reactant (s) to the transition state.
The volume of activation, as derived from the pressure dependence of the observed rate constant of a chemical reaction, is discussed in general terms, rather than a systematic treatment of various classes of reactions, which are in fact reported elsewhere (1–7).
