Description and criteria

Clinical descriptions and criteria for diagnosis of disorders of mood will only be mentioned in passing. The reader should consult standard reference sources for this material. Here we will discuss how discoveries of various antidepressants have impacted the diagnostic criteria for depression and how they may have modified the natural history and course of this illness. The goal of this chapter is to acquaint the reader with current ideas about the clinical and biological aspects of mood disorders in order to be prepared to understand how the various antidepressants and mood stabilizers work.

Scale-up and performance of a 1.47-m Scheibel column have been reported (98,154,155), as have detailed description and design criteria for the Scheibel column (156) and scale-up procedures (157). The same stage efficiency can be maintained on scale-up, and total throughput can be increased by three and one-half times at the expense of higher HETS. As of this writing, Scheibel columns up to 2.75 m in diameter are in service. 

The rotating-disk contactor (RDC), developed in the Netherlands (158) in 1951, uses the shearing action of a rapidly rotating disk to interdisperse the phases (Eig. 15b). These contactors have been used widely throughout the world, particularly in the petrochemical industry for furfural [98-01-1] and SO2 extraction, propane deasphalting, sulfolane [126-33-0] extraction for separation of aromatics, and caprolactam (qv) [105-60-2] purification. Columns up to 4.27 m in diameter are in service. An extensive study (159) has provided an excellent theoretical framework for scale-up. A design manual has also been compiled (160). Detailed descriptions and design criteria for the RDC may also be found (161). 

The Oldshue-Rushton column (Eig. 15d) was developed (162) in the early 1950s and has been widely used in the chemical industry. It consists essentially of a number of compartments separated by horizontal stator-ring baffles, each fitted with vertical baffles and a turbine-type impeller mounted on a central shaft. Columns up to 2.74 m in diameter have been reported in service (162—167). Scale-up is reported to be reliably predictable (168) although only limited performance data are available (169). A detailed description and review of design criteria are available (170). 

Kuhni contacters (Eig. 15e) have gained considerable commercial application. The principal features are the use of a shrouded impeller to promote radial discharge within the compartments, and a variable hole arrangement to allow flexibility of design for different process applications. Columns up to 5 m in diameter have been constmcted (176). Description and design criteria for Kuhni extraction columns have been reported (177,178). 

Having decided on the vacancies that need filling, determine the number of people needed for each role. This should be done in accordance with the number of mentees and mentors you are planning to recruit. Then you can draw up job descriptions and selection criteria for each of the vacancies. With regard to the selection criteria for trainers, relationship supervisors and (if still necessary) the program co-ordinator, please refer back to Founding the implementation team and Table 8.1. 

Another point to remember in mentor selection is that the mentors you want to recruit might be very different from each other, requiring distinct job descriptions and selection criteria. This is due to the fact that the mentor target groups (and their associated criteria) are determined by the organization s and the mentees needs and objectives, as well as by the mentoring schemes that were selected. 

In the following description and discussion of our results, various criteria derived from the literature are used to determine whether or not each sample is of adequate preservation to allow it to be confidently included in a stable isotope study. The values applied in the various criteria have been found to be associated with archaeological bone collagen that retained an isotopic composition that was reflective of its diet, while the majority of samples that had values outside of the criteria did not retain an isotopic composition that reflected diet. The values for these criteria may vary slightly depending upon the collagen extraction methodology used, and such criteria are not exact. In this study samples that fall within the criteria values are deemed acceptable, and those that do not are deemed unacceptable. ... 

Rinard dedicated his research to a detailed analysis of methodological aspects of a micro-reactor plant concept which he also termed mini-plant production [85] (see also [4, 9, 10] for a commented, short description). Important criteria in this concept are JIT (Just-in-time) production, zero holdup, inherent safety, modularity and the KISS (keep it simple, stupid) principle. Based on this conceptual definition, Rinard describes different phases in plant development. Essential for his entire work is the pragmatic way of finding process solutions, truly of hybrid character ]149] (miniaturization only where really needed). Recent investigations are concerned with the scalability of hybrid micro-reactor plants and the limits thereof ]149], Expliddy he recommends jointly using micro- and meso-scale components. 

Test plans should include definite, measurable acceptance criteria, in addition to the amount of testing to be done. The test plan should include the data sets to be used and the detailed instructions for testing. Errors encountered during testing must be documented, including how they were discovered, their description, and any action taken to remedy the error. Errors must be remedied prior to the release of the software or computer system. Test results must be documented clearly to allow for pass/fail determinations to be made. 

The dilemma related to the details of a process description is fundamental. Generally, one should reach a point where a process description and the experimental potential for its quantification are optimal. The criteria for this optimum is a quantification of those processes relevant for the sewer performance focused on, expressed with sufficient accuracy, applicable under real conditions and at the same time in agreement with methods for a sound determination of model parameters. 

Comments on some trends and on the Divides in the Periodic Table. It is clear that, on the basis also of the atomic structure of the different elements, the subdivision of the Periodic Table in blocks and the consideration of its groups and periods are fundamental reference tools in the description and classification of the properties and behaviour of the elements and in the definition of typical trends in such characteristics. Well-known chemical examples are the valence-electron numbers, the oxidation states, the general reactivity, etc. As far as the intermetallic reactivity is concerned, these aspects will be examined in detail in the various paragraphs of Chapter 5 where, for the different groups of metals, the alloying behaviour, its trend and periodicity will be discussed. A few more particular trends and classification criteria, which are especially relevant in specific positions of the Periodic Table, will be summarized here. 

In a more detailed description and according to Nesper (1990), the criteria for defining the Zintl phases may be summarized in the following points ...
