Formulation definition

Apart from being complex, the human immune system also changes during the body s growth and development. The defense mechanisms involved in building immunity are equally complex. Thus, it is extremely difficult to formulate definite statements on the effect of particular environmental components on the immunological tolerance of a human body, including the impact of diet on the immune system. Until now, the research on human nutrition has focused primarily on the effect of... 

Many examples of polycyclic alkene osmylations have been reported in the literature in connection with the syntheses of specific target molecules such as alkaloids, prostanoids, or steroids. However, carefully determined diastereomer ratios are usually not available. Due to the varied nature of these substrates, it is not possible to formulate definite rules for diastereo-face differentiation except in specific cases. Thus, for example, the exclusive exo reactivity of bridged systems such as bicyclo[2.2.1]heptene derivatives (norbornene-type) is well known as Alder s rule of exo addition63. 

The relative solubilities of compounds are of great importance in connection with recrystallization and extraction. It is difficult to formulate definite rules as to what solvent or type of solvent to use. However, many common solvents are listed in Table 2-5, and their relative behavior with naphthalene will serve as something of a guide as to which solvent to use. 

Furthermore, relatively little progress has been made in formulating definite physical models to explain quantitatively the small-signal transfer functions which have been measured with reactor oscillators. For example, in the case of EBR-1, Mk 1, the first mechanically unstable core of the experimental breeder, it proved impossible to find the origin of the large delayed negative temperature coefficient needed to explain the very long... 

Hill and co-workers [28] give some well-formulated definitions ... 

In the case of motor fuels, when the content of the material added is relatively high, we will use the term components of the mixture. Thus the ethers, used in the formulation of motor fuels in significant proportions, will not be Included in our definition. 

To gain a proper perspective of the role of computed physical properties, the relationship between estimated and computed properties needs to be understood. A thorough reading of Horvath (25) permits formulation of the following definitions of estimating or computing properties. 

Thermodynamics. Many definitions and formulations exist for the laws of thermodynamics, a detailed treatment of which may be found in standard engineering texts (2). Definitions that apply best to air conditioning are as follows ... 

The first attempt to formulate a systematic nomenclature for polymers was based on the smallest repeating stmctural unit it was pubHshed in 1952 by a Subcommission on Nomenclature of the lUPAC Commission on Macromolecules (95). The report covered not only the naming of polymers, but also symbology and definitions of terms. However, these nomenclature recommendations did not receive widespread acceptance. Further progress was slow, with a report on steric regularity in high polymers pubHshed in 1962 and updated in 1966 (96). 

Equation 54 implies that U is a function of S and P, a choice of variables that is not always convenient. Alternative fundamental property relations may be formulated in which other pairs of variables appear. They are found systematically through Legendre transformations (1,2), which lead to the following definitions for the enthalpy, H, Hehnholt2 energy,, and Gibbs energy, G ... 

U.S. definitions and standards for chocolate are quite specific (19). Sweet chocolate must contain at least 15% chocolate Hquor by weight and must be sweetened with sucrose or mixtures of sucrose, dextrose, and com symp soflds ia specific ratios. Semisweet chocolate and bittersweet chocolate, though often referred to as sweet chocolate, must contain a minimum of 35% chocolate Hquor. The three products, sweet chocolate, semisweet chocolate, and bittersweet chocolate, are often simply called chocolate or dark chocolate to distinguish them from milk chocolate. Table 6 gives some typical formulations for sweet chocolates (5). 

The reasons (i.e., the motivations, concerns, activators, and needs) for considering the use of QRA define the requirements for information. The next question is, can QRA supply the appropriate information to satisfy the need By definition, QRA studies generate numerical estimates of the expected frequency and/or consequence(s) of undesired events. The results of the QRA can be formulated and used on two bases (1) an absolute basis and (2) a relative basis. 

The Severe Accident Policy Statement formulates systematic safety examinations for detection of accident vulnerabilities and implementation of cost-effective changes. The NRC issued Generic Letter 88-20 to implement this plan through IPEs. While the primary goal was the identification of plant vulnerabilities, no definition of vulnerability was provided. Only 4 operators of BWRs identified vulnerabilities and only 16 operators of PWRs did so. Over 500 plant improvements were identified, but few vulnerabilities were. 

Piezoelectric solids are characterized by constitutive relations among the stress t, strain rj, entropy s, electric field E, and electric displacement D. When uncoupled solutions are sought, it is convenient to express t and D as functions of t], E, and s. The formulation of nonlinear piezoelectric constitutive relations has been considered by numerous authors (see the list cited in [77G06]), but there is no generally accepted form or notation. With some modification in notation, we adopt the definitions of thermodynamic potentials developed by Thurston [74T01]. This leads to the following constitutive relations ... 

Conditional probability also can be used to formulate a definition for the independence of two events A and B. Event B is defined to be independent of event A if and only if... 

The original formulation of de Bruijn s theorem was for a quite general problem of this type, with a broad definition of the "weight" of a mapping. We assume that R is the union of a finite number of pairwise disjoint sets R- (i = 1,. .., k and that // is a direct product of groups //j, where //j acts on / j. For each there is a weight function where n is the number of elements of D that are... 

Thus, the formulated classification allows for the definition of the compound s crystal structure type based on its composition. In this process, the most important stage is the correct definition of the X Me ratio.
