Definition and description

The RAC and processed commodities to be collected for each crop are listed in OPPTS 860.1000. Close attention should be paid to the definition and description of many of the commodities listed in the footnotes to Table 1. Reviewing a summary of the actual commercial processing practices for the crop may be helpful. Once the processing procedures and the agronomic practices to be simulated in the field residue trial are understood, a field study can be designed that will truly represent commercial production and processing practices. This will ensure that the study will yield useful, reliable, and accurate data to be used in the tolerance setting process. 

Based on these definitions and descriptions, classification of chemical products can be performed in a more scientific way, without ambiguities and/or overlap. These classifications should help to understand the nature of some products and to organize their study. This preliminary approach is expected to give examples and/or methodologies of design using these principles in the near future. 

Note 7 There are definitions of linear viscoelasticity which use integral equations instead of the differential equation in Definition 5.2. (See, for example, [11].) Such definitions have certain advantages regarding their mathematical generality. However, the approach in the present document, in terms of differential equations, has the advantage that the definitions and descriptions of various viscoelastic properties can be made in terms of commonly used mechano-mathematical models (e.g. the Maxwell and Voigt-Kelvin models).

The Codex Alimentarius Commission, in its Draft Provisional Standard34 (following definition and description, and subsidiary definitions and designations) has laid down certain compositional criteria. It is obvious that all definitions of honey so far discussed deal with two chemically and physically distinct commodities namely, nectar honey and honeydew honey. A comparison between the two shows that honeydew honey is lower in D-fructose and D-glucose and higher in pH, oligosaccharides, acidic components, ash, and nitrogen than nectar honey. 

Detonation (or Explosion) by Infuluence or Sympathetic Detonation. Its definition and description are given in Vol 1, p X and in Vol 4, pp D395-R to D398-R. Its tests are listed on pp D398-R to D402-L and also under Booster Sensitivity Tests. 

Writing in the seventeenth-century textbook tradition, Lemerys book opens with a brief introductory section offering comments on chymistry in general, its definition and descriptions of its apparatus and basic procedures. The rest of the book is divided into three parts dealing with recipes for drugs derived from the mineral, vegetable, and animal kingdoms. The... 

The natural occurrences of montmorillonites are varied and complex, as is the mineralogy of this mineral group. They are particularly variable chemically, due in part to the completely undefined interlayer ion position which can be occupied in part or entirely by almost any cation except silicon. Definitions and descriptions of these expandable minerals are necessarily vague since the response of these interlayer ions to different chemical and thermal treatments is the most current method of identification for minerals in the group. This leaves the basic 2 1 structure identified in many cases. A broad differentiation of the basic... 

Isidorus Hispalensis or Isidorus of Seville was a writer of the seventh century who wrote a work on the origin and signification of words. For such definition and descriptions as pertain to natural science he was dependent upon Greek and Latin authors with no infusion of Arabian science. Throughout the middle ages Isidorus was a much respected authority. A modern Latin text, edited by W. M. Lindsay, was published in Oxford in two octavo volumes in 1911. 

Fig. 12.5 Illustration of the orientation angles used in the Stockmayer intermolecular potential. Molecule j consists of atoms A and B, and molecule i consists of atoms C and D. The vector ry runs from the center of mass of molecule i to the center of mass of molecule j. The vector JTJ gives the orientation and magnitude of the dipole moment of molecule i, with a similar definition for JTj. A ghost copy of molecule j is shifted to left to more easily visualize the orientation angle ifr. See Eqs. 12.11 to 12.13 and accompanying text for definition and description of these angles.

While the general idea of differentiating monitoring site types is present in all the monitoring strategies, the site type definitions and descriptions are different. The USA approach starts with different scales of representativity which are then linked to... 

This standard contains terms, related definitions, and descriptions of terms used, or likely to be used, in fire standards and fire-risk standards. 

There is a perfect parallel between the behavior of weak bases and weak acids. The definition and description of weak acids, the existence of and the production of H O iaq) ion when they are dissolved in water can be applied directly to weak bases, the existence of Kb, and the production of OH aq) ion. A weak base such as ammonia reacts only partially with water to produce OH (d q() ... 

The general section of Part C contains the definitions applicable to the regulations. Of Interest is the definition and description of child-resistant packaging and the associated test methodology. 

Huge advances have been made over the last 15 years in the research, development, application, commercialization and understanding of the mechanisms of action of nanoscale drug delivery systems. Many of these advances have had a spectacular impact on the prevention, diagnosis and treatment of a wide range of diseases. This is especially trae in the treatment of many cancers, and it is in the oncology field that the majority of the formulation advances have been made. Pharmaceutically, the most important nanotechnologies are exemplified and discussed below (see Table 39.10 for definitions and descriptions). 

Many definitions and descriptions of HAT, prior to the emergence of PCET as a field of study, did not adequately take into account the complexity embodied by Fig. 17.1. HAT is traditionally defined as the transfer of an electron and a proton from one location to another along a spatially coincidental pathway. In this case, the electron and proton are donated from one atom and they are accepted by another atom. These transfers are well described mechanistically as the diagonal pathway of Fig. 17.1 and they have been treated formally by a number of investigators [3, 4]. However, many reactions treated within a formalism of HAT are more complex as ET and PT are site-differentiated either along uni- or bidirectional pathways. As will be discussed in this chapter, traditional descriptions of HAT do not address how the electron and proton transfer events are coordinated mechanistically in these more complicated reactions and more general treatments of PCET are warranted. 

To develop a product from inception to market, the product and process have to be optimised and the process scaled up and transferred to commercial production. Definitions and descriptions of the requirements for all these stages of development are discussed in Chapter 8, although the major discussion is on the preformulation/formulation input to product optimisation. The many factors which a formulator should consider in the selection of pharmaceutical excipients and packaging are discussed. Useful sources of information and techniques for selection such as expert systems and experimental design tools are included. 

This has opened the way to a systematic, quantum chemical definition and description of functional groups, to macromolecular shape analysis, to macromolec-ular force computations, and to shape-code-based macromolecular similarity analysis [20-25],... 

It seems advisable first to define and describe the phenomena of oxidation and reduction from the newer chemical viewpoints, and then to apply these definitions and descriptions to a number of reactions.
