Particular subject

Wire cords are particularly subject to degradation of their adhesion values by moisture. To combat this, halogenated butyl (HIIR) is used in tire innerliners because of its property of low air and water vapor diffusion rates. Moisture is present in most air pumps and many tires are mounted with water left in the tire on mounting. For these reasons tires and tire compounds are tested extensively at simulated aging conditions in the laboratory and on test vehicles before they are sold to the customer. [Pg.252]

Staff do not work to policies but in fact work in accordance with procedures which themselves direct actions and decisions within the framework of the stated policies. In order to make the decisions required in the procedures, staff will often need to know the company policy on a particular subject, such as procurement, recruitment, release of product, licensing agreements, agreeing design changes, etc. Can they or can they not do something and if so what criteria would they satisfy ... [Pg.165]

CT+-values may not differ too widely from ct-values. Since the charges in 2 and 4 actually reside in the ring, the pyridine system may, in addition, be particularly subject to the variability of cr-values, and consequently a careful analysis of some rather extensive material in the sense of some of the most refined methods might be very profitable... [Pg.217]

In general, the specialist may often be much more of an expert in a particular subject under this system than under the generalist approach, and consequently more depth into the pertinent factors of a problem may come... [Pg.44]

Improper sampling can introduce errors originating at the surface (8.7) because x-ray emission spectrography operates only on a surface layer of critical thickness (6.4). Powders are particularly subject to errors that result from segregation and lack of uniformity in general (7.8, 7.15). Nonuniform residues from the evaporation of solutions can be troublesome. [Pg.288]

Community-wide regulation of medical devices commenced with the introduction of Council Directive 90/385/EEC of 20 June 1990 on the approximation of the laws of the Member States relating to active implantable medical devices. Two further base directives followed that cover all other medical devices The Medical Devices Directive 93/42/EEC and The In Vitro Diagnostics Directive 98/79/EC. All three base directives are similar in content and structure. However, it should be noted that, in addition to dealing with the particular subject matter, the Medical Devices Directive and the In Vitro Diagnostics Directive also contained amendments to the previous device directives. The Medical Devices Directive amended articles in the Active Implantable Medical Devices Directive, while the In Vitro Diagnostics Directive amended articles in the Medical Devices Directive. [Pg.10]

The author index is compiled by computer from the lists of references. Thus it tells whose publications are cited and in that respect is comprehensive. It is not a list of authors, beyond those cited in the references, whose results are reported in the text. However, as the references cited are leading ones, consulting them, along with the use of appropriate works of the secondary literature, will rapidly lead to the complete literature related to any particular subject covered. [Pg.18]

The reason for this lies not least in the increasing instrumentalization and delibei automation of all those processes which were earlier particularly subject to eri (Fig. 2). Modem high performance thin-layer chromatography (HPTLC) is no Ion inferior to other liquid chromatographic techniques with respect to precision and s sitivity (Fig. 3) [6]. [Pg.743]

The correlation is valid in the range 0.25 m < /// < 0.6 m. Equation 9.63 tends to predict low values of Kr and hence can be considered to be conservative, especially at high pressures and high liquid rates. Also, the system might be subject to foaming, in which case Kr must be decreased to allow for this. For a system particularly subject to foaming, the value of Kt from Equation 9.63 should be multiplied by a factor that is less than unity to allow for this13 ... [Pg.172]

Bz s-imidoesters like DMS may be used to couple proteins to PE-containing liposomes by crosslinking with the amines on both molecules (Figure 22.24). However, single-step crosslinking procedures using homobifunctional reagents are particularly subject to uncontrollable polymerization of protein in solution. Polymerization is possible because the procedure is done with the liposomes, protein, and crosslinker all in solution at the same time. [Pg.892]

Like so many other reactions, the ene reaction has been given new life by metal catalysis. The use of metals ranges from common Lewis acids, which simply lower the barrier of activation of the hetero-ene reactions to transition metal catalysts which are directly involved in the bond-breaking and -forming events, rendering reactions formal ene processes. This review is meant to serve as a guide to the vast amount of data that have accumulated in this area over the past decade (1994-2004). If a particular subject has been reviewed recently, the citation is provided and only work done since the time of that review is included here. Finally, the examples included within are meant to capture the essence of the field, the scope, limitations, and synthetic utility therefore, this review is not exhaustive. [Pg.557]

For example, the subject-observer pattern uses a set of actions that enables the following the subject to notify its observers of changes the observer to query the subject about its state and the observer to register and deregister interest in a particular subject. These actions, taken as a set, form a collaboration. When several actions have the same participants, it is convenient to draw them on top of one another. The collaboration in Figure 4.12 describes a set of three actions between retailers and wholesalers. This collab-... [Pg.197]

Figure 9.11 on the next page shows the collaboration framework as we would normally draw it. The subject-observers association links particular instances of the two types, and the update action applies only to Observers that have a current Subject. The register action links a particular Subject to a particular Observer. It is a joint action We have not specified here how it happens or even to whom you send the message to make it happen we have specified only that there should be such an action, with responsibility for executing it distributed somehow between Subject and Observer. When designers apply the framework to a particular pair of types, it tells them to provide this facility. [Pg.374]

Much has been written in recent years about unit operations, but very little about unit processes. It is strange that this particular subject which means so much to every chemical engineer should have received... [Pg.65]

The most difficult to interpret of the available evidence is the nature of the vibrational spectra of the OH stretching regions of H20(as) and liquid H20. This particular subject is a minefield littered with conflicting opinions and sometimes emotionally held positions. I do not pretend that the following discussion is definitive, but I think it is consistent with the other information available to us. [Pg.182]

This book does not aim to be an all-inclusive text, rather a companion to other books you will already have in your collection. It aims to allow you to have an additional reference point when revising some of these difficult topics. It will enable you to quickly and easily bring to hand the key illustrations, definitions or derivations that are fundamental to the understanding of a particular subject. In addition to succinct and accurate definitions of key phrases, important equations are derived step by step to aid understanding and there are more than 180 diagrams with explanations throughout the book. [Pg.261]
