Adherants, classification

After an area classification has been established, then anelectrical equipment, instruments, and wiring must adhere to that classification. Therefore, some motor enclosure types would not be electrically acceptable for specific area classifications. 

Woolfson and Mahmoud have classified the routes to preparation of decorated self-assembling peptide materials [53] as (1) co-assembly, where the functional part is already attached to a self-assembling component prior to assembly, and (2) postassembly, where a non-functionahsed self-assembled structure is modified by covalent or non-covalent means. This discussion adheres to this classification. A third route, beyond the scope of this review, is the use of structured peptides as templates for inorganic materials. Section 4.1 discusses functionalised self-assemblies formed from co-assembly-type approaches, while post-assembly modifications of self-assembled structures are considered in Sect. 4.2. 

MAO Is have not been evaluated systematically for treatment of PD under the current diagnostic classification and generally are reserved for patients who are refractory to other treatments.48,49 MAOIs have significant side effects that limit adherence. Additionally, patients must adhere to dietary restriction of tyramine and avoid sympathomimetic drugs to avoid hypertensive crisis. 

From the structural viewpoint there is much to commend the classification of problems based on the topology of the pipeline network— single branch pipelines, tree networks, and cyclic networks. However, since some methods are applicable to more than one category, rigorous adherence to this classification will lead to unnecessary duplication and overlaps. 

A reasonable organization of flow types on the basis of the mechanism of transport requires detailed theoretical analysis and extensive data. Perhaps for this reason, the majority of investigators with less comprehensive data have adhered to a classification based on visual observation of flow patterns. In the following sections both types of flow description will be used, and defined, with pattern referring to visual observations, and type or regime being applied to flow behavior which can be described by more quantitative expressions. 

It is essential always to ensure that there is clear understanding of how terms are being used, and there is considerable confusion between authorities using the same terms. In this chapter the following definitions will be used. They adhere as far as possible at least to the concepts, if not the actual text, used in the World Health Organisation s International Classification of Diseases 10th ed. (ICD 10) ... 

The classification of the 2s and 2p atomic orbitals of the central oxygen atom. The 2s(0) orbital transforms as Gg, the 2px and 2p orbitals transform as the doubly degenerate nu representation, and the 2pz orbital transforms as om+. In some texts the + and superscripts are omitted, but throughout this one there is strict adherence to the use of the full symbols for all orbital symmetry representations. Unlike the 90° case, the 2s and 2p7 orbitals have different symmetry properties so there is no question of their mixing. 

Fire hazard is viewed from the standpoint of safety, to which in the United States, the Occupational Safety and Health Standard (OSH) is often used as the basis for classification of flammables versus a combustible material. Additionally, the U.S. Department of Transportation also has very specific definitions regarding classification of fire hazards based on safe transport of materials. For initial discussions we will adhere to the OSHA definitions, and later refer to distinctions in U.S. federal definitions which are legal standards. 

We arbitrarily define the nrajority of metal ions in oxidation states II and III as being in normal oxidation states, but we do not adhere rigorously to this classification. 

Classification of Equipment.—Equipment for the mechanical handling of materials may be classified as the carriers which carry the material in a limited but continuous stream (endless conveyors and elevators), and the hoists, trucks and railways which carry more concentrated, and frequently more compact, loads more or less intermittently. This classification will be adhered to so far as practical to simplify a logical selection of handling equipment for the industrial establishment and consideration of equipment will parallel the passage of the material, commencing with its delivery. 

Tumor that is adherent to other organs or structures macroscopically is classified T4. However, if no tumor is present in the adhesion microscopically, the classification should be pTs. The V and L substaging should be used to identify the presence or absence of vascular or lymphatic invasion.
