Treatment generic

Surface treatment Generic term for processes applied to surfaces to achieve a surface condition of the adherends suitable for a bonded j oint or to optimize them in view of their adhesiveness. Such processes are divided into surface preparation, pretreatment and post-treatment.

The generic term azulene was first applied to the blue oils obtained by distillation, oxidation, or acid-treatment of many essential oils. These blue colours are usually due to the presence of either guaiazulene or velivazulene. The parent hydrocarbon is synthesized by dehydrogenation of a cyclopentanocycloheptanol or the condensation of cyclopentadiene with glutacondialdehyde anil.

Monta.n Wax. An important product of the direct extractive treatment of lignitic coals is montan wax [8002-53-7]. The term montan wax or Bergwachs refers strictiy to the material obtained by solvent extraction of suitable German brown coals. The generic term for similar materials is montana wax. The small quantities made outside Germany are usually referred to as montan, prefixed by the country of origin (see Waxes). 

L-Dopa and Trimethoprim are two other dmgs that can be made from vanillin. u-Dopa is used for the treatment of Parkinson s disease Trimethoprim is an antiinfective agent used mainly for urinary tract infections and certain venereal diseases. Also, Mebeverine, an antispasmodic agent, and Verazide, a generic antitubercular agent, are dmgs that can be made from vanillin or its derivatives. 

The sales of oral diuretics are declining, and are forecast to continue their decline in constant dollars during the 1990s (119,120). Several possible explanations can be offered for these trends. The patents of market leaders are expiring, lea ding to the introduction of generic brands at ca 40% below the cost of the branded market leaders physicians are switching to newer treatments for hypertension, eg, calcium channel blockers and... 

Table 3 lists the structures and generic names of the principal penicillins in current medical usage, and Table 4 indicates in summary form the relative antibacterial properties of these compounds. The reader is urged to consult reviews such as (B-77MI51106) for a more complete treatment, since summaries such as Table 4 inevitably omit a large amount of important detail. 

Of the generic aluminium alloys (see Chapter 1, Table 1.4), the 5000 series derives most of its strength from solution hardening. The Al-Mg phase diagram (Fig. 10.1) shows why at room temperature aluminium can dissolve up to 1.8 wt% magnesium at equilibrium. In practice, Al-Mg alloys can contain as much as 5.5 wt% Mg in solid solution at room temperature - a supersaturation of 5.5 - 1.8 = 3.7 wt%. In order to get this supersaturation the alloy is given the following schedule of heat treatments. 

Table 4 allows a generic identification of the various technology options suitable for treating wastes based on their hazardous characteristics and physical form Table 4 also identifies the kinds of data which must be collected to perform a valid evaluation of those technologies. The physical treatment data needs for different media shown in Table 5 are typically required in addition to those presented in Table 4.

Similarly, the Site B contractor s SSAHP provided corporate policy and procedures for permit-required confined space entry but lacked the site-specific detail necessary to describe the application of the corporate policy to procedures at the site. For example, the SSAHP did not identify specific components of the thermal treatment unit that presented confined space hazards, nor did it describe the specific circumstances or procedures that would require employee entry into these areas. In addition, the plan stated that the contractor would maintain an onsite employee confined space rescue team, but did not identify the members of this team. The SSAHP for Site F also contained a generic confined space entry program but did not identify the specific location of confined space hazards present at the site. 

The nuclear equipment failure rate database has not changed markedly since the RSS and chemical process data contains information for non-chemical process equipment in a more benign environment. Uncertainty in the database results from the statistical sample, heterogeneity, incompleteness, and unrepresentative environment, operation, and maintenance. Some PSA.s use extensive studies of plant-specific data to augment the generic database by Bayesian methods and others do not. No standard guidance is available for when to use which and the improvement in accuracy that is achieved thereby. Improvements in the database and in the treatment of data requires, uhstaiui.il indu.sinal support but it is expensive. 

Chapter 5—CCPS Generic Failure Rate Data Base Contains tables of generic process equipment reliability data that are structured by the CCPS Taxonomy. The data are extracted from data resources in Chapter 4. The chapter includes a discussion of the selection, treatment, and presentation of the data in the Tables. 

In connection with electronic strucmre metlrods (i.e. a quantal description of M), the term SCRF is quite generic, and it does not by itself indicate a specific model. Typically, however, the term is used for models where the cavity is either spherical or ellipsoidal, the charge distribution is represented as a multipole expansion, often terminated at quite low orders (for example only including the charge and dipole terms), and the cavity/ dispersion contributions are neglected. Such a treatment can only be used for a qualitative estimate of the solvent effect, although relative values may be reasonably accurate if the molecules are fairly polar (dominance of the dipole electrostatic term) and sufficiently similar in size and shape (cancellation of the cavity/dispersion terms). 

The thermodynamics treatment followed in this volume strongly reflects our backgrounds as experimental research chemists who have used chemical thermodynamics as a base from which to study phase stabilities and thermodynamic properties of nonelectrolytic mixtures and phase properties and chemical reactivities in metals, minerals, and biological systems. As much as possible, we have attempted to use actual examples in our presentation. In some instances they are not as pretty as generic examples, but real-life is often not pretty. However, understanding it and its complexities is beautiful, and thermodynamics provides a powerful probe for helping with this understanding.
