Applications and Restrictions

All LEED data analysis must, however, rely on prior assumptions and model distributions and is, therefore, not really direct. Microscopic methods have the advantage of delivering directly the shape of the surface (domains, terraces, etc.) without any assumptions being made.

Equation 169, the fundamental residual property relation, is so general as to be useful for practical application only in restricted forms. Division by dP and restriction to constant T and composition leads to equation 17 ... 

Unfortunately for PPO its price is too great to justify more them very restricted application and this led to the introduction of the related tmd cheaper Noryl materials in 1966 by the General Electric Corporation. These will be discussed in the next section. In recent years the only sources of unmodified PPO have been the USSR (Aryloxa) and Poland (Biapen). 

Provide employee accident experience for the past 5 years, including the current year. The submittal shall specifically include OSHA recordable cases rate, lost and restricted workday cases rate, vehicle accident rate, and number of fatalities with a description of each. The workers compensation interstate experience modification rate should be less than 1.0, and applicable SIC codes should be noted. 

Both globulins exert their effect by depletion of circulating lymphocytes either by complement-dependent lysis or by phagocytosis after opsonization. However, antilymphocyte globulin (ALG) and antithymocyte globulin (ATG) are nonhuman polyclonal antibodies. To prevent sensitization application is restricted to a time period of several days only. 

Tg = Tg h), in addition to the usual one t6 < 1. However, this restriction is sufficiently weak in real-life situations and, therefore, it is meaningless to speak about any practical advantage of the three-layer scheme. For this reason the two-layer scheme is quite applicable and more efficient in practical implementations. 

Concerned mainly with the security of explosives and restricted substances. Applicable to the acquisition, keeping, handling and control of explosives, e.g. blasting explosives, detonators, fuses, ammunitions, propellants, pyrotechnics and fireworks. 

Hydrate control is not included in this chapter, but is discussed in Chapter 13 because of the relative importance and difference in chemical mechanism. Many chemicals added to water will result in a depression of the freezing point. The practical application is restricted, however, because of some other unwanted effects, such as corrosion, destruction of rubber sealings in engine parts, or economic aspects. 

Fluorescence is much more widely used for analysis than phosphorescence. Yet, the use of fluorescent detectors is limited to the restricted set of additives with fluorescent properties. Fluorescence detection is highly recommended for food analysis (e.g. vitamins), bioscience applications, and environmental analysis. As to poly-mer/additive analysis fluorescence and phosphorescence analysis of UV absorbers, optical brighteners, phenolic and aromatic amine antioxidants are most recurrent [25] with an extensive listing for 29 UVAs and AOs in an organic solvent medium at r.t. and 77 K by Kirkbright et al. [149].
