Competence definition

Faber, K., Notes on two competing definitions of multivariate sensitivity, Anal. Chim. Acta., 381, 103-109, 1999. [Pg.161]

Categories that cause problems for this definition of chemical substance include (1) enantiomers (species containing equal amounts of two optical isomers, like I- and d-tartaric acid) (2) azeotropic mixtures (3) dissociative compounds in equilibrium (4) certain types of mixed crystals or other polymorphic compounds (e.g,d- and /-camphoroxime) (5) synthetic polymers (6) many biochemical compounds (7) systems that are not in "pure" thermodynamic equilibrium and (8) isotopes. In each case, pragmatic decisions have to be made, as the notion of pure substance cannot be essen-tialized. There are no competing definitions of "pure substance" that can avoid the need for "inspired adhoccery" to deal with difficult cases. [Pg.173]

In addition to the above, the SCANS Report will contain the standard wording for a variety of other competencies. Whm the need arises, describe yourself by slightly rephrasing words, e.g. competency definitions in the SCANS report. Be aware, however, that you will need personal examples of competencies ready to discuss. If you can t provide an example, the competency may not be claimed. Fill any gaps with an example, even if it may seem minor and inconsequential. Another advantage of this action is that you... [Pg.22]

Where additional guidance exists for the competency category then the full framework points to where this is available, i.e. the framework does not repeat existing guidance. In the majority of cases this points to the competency definitions contained in the lET/BCS Blue Book. For example ... [Pg.223]

This standard proposal is limited to a format model. So, as it had been pointed out earlier, the implementation of this format requires some complementary work, which can partly be standardized. The definition of the Application Programming Interfaces (A.P.l.) could become a standard in the future. Nonetheless, this would require the creation of a new ad hoc group, with different technical competences. [Pg.927]

Definitive examples of intrinsic non-RRKM dynamics for molecules excited near their unimolecular tluesholds are rather limited. Calculations have shown that intrinsic non-RRKM dynamics becomes more pronounced at very high energies, where the RRKM lifetime becomes very short and dissociation begins to compete with IVR [119]. There is a need for establishing quantitative theories (i.e. not calculations) for identifying which molecules and energies lead to intrinsic non-RRKM dynamics. For example, at thenual... [Pg.1037]

The kinetic chain length has a slightly different definition in the presence of chain transfer. Instead of being simply the ratio Rp/R, it is redefined to be the rate of propagation relative to the rates of all other steps that compete with propagation specifically, termination and transfer (subscript tr) ... [Pg.389]

This section provides an overview of important definitions and terminology that the Hazardous Materials Worker and Emergency Response Personnel should know. Emergency response at sites other than hazardous waste clean-up sites are emphasized. Under OSHA s 29 CFR1910.120 emergency response personnel (that will take some action to control the situation other than call for help) shall be trained to a competence to protect themselves and other employees in ... [Pg.1]

Definition of competence assessment methods. The definition of formal methods of assessing competence is a neglected area in many training programs. It is obviously necessary to ensure that trainees possess the necessary skills to do the job at the end of the training program. [Pg.131]

The reader may remember the brief definition of a competent person, i.e. he must know what to look for and how to recognize it when he sees it . Perhaps what has been described in this section gives further insight as to how appropriate this definition is. [Pg.145]

If, for the purpose of comparison of substrate reactivities, we use the method of competitive reactions we are faced with the problem of whether the reactivities in a certain series of reactants (i.e. selectivities) should be characterized by the ratio of their rates measured separately [relations (12) and (13)], or whether they should be expressed by the rates measured during simultaneous transformation of two compounds which thus compete in adsorption for the free surface of the catalyst [relations (14) and (15)]. How these two definitions of reactivity may differ from one another will be shown later by the example of competitive hydrogenation of alkylphenols (Section IV.E, p. 42). This may also be demonstrated by the classical example of hydrogenation of aromatic hydrocarbons on Raney nickel (48). In this case, the constants obtained by separate measurements of reaction rates for individual compounds lead to the reactivity order which is different from the order found on the basis of factor S, determined by the method of competitive reactions (Table II). Other examples of the change of reactivity, which may even result in the selective reaction of a strongly adsorbed reactant in competitive reactions (49, 50) have already been discussed (see p. 12). [Pg.20]

There is no all encompassing definition issued by either ISO or any other competent international body. [Pg.275]
