Appraisal, preliminary

An appraisal of artificial weathering methods was given in a report by Hoey and Hipwood who described the effectiveness of various weatherometer tests such as are described in BS 3900 Part F3 and ASTM 42 1964 (now ASTM G23 1989). Although these tests simulate atmospheric exposure it is not possible to obtain a direct correlation owing to variation in outdoor exposure conditions from place to place, but they serve a very useful purpose in providing a preliminary sorting of paints that can then be tested in the field.

Though still only very incompletely explored and subject to major revisions, Canada s coal resources are so extensive as to place this country among the most richly coal-endowed nations Ql>. ->3). Recent appraisals (Table I) set ultimate in-place resources in >2h ft thick seams under less than 2500 ft of cover at some 518 billion tons and preliminary estimates from deeper testhole logs suggest that similar, if not even larger, tonnages may lie in coal occurrences at depths between 2500 and 4500 feet. 

Further project evaluation (post-project appraisal) should be based on project objectives. Therefore, the main objectives must be explicitly defined in the preliminary study of any project. For many restoration projects, no clear objectives were ever formulated and consequently it is not really possible to assess their final success. The objectives should include elements of the environment/ecology, the economy and society. According to Reichert et al. [12], objectives can be divided into fundamental objectives (directly related to what a decision maker would like to achieve) and means objectives (leading to the accomplishment of fundamental objectives). Fundamental objectives are structured hierarchically. In the Rhone-Thur project, we used a hierarchy of fundamental objectives [12,13] that can be used for other restoration projects (Fig. 3). 

The most convenient and economic techniques of choice for the rapid analysis of starting materials and for the assessment of purity of a crude reaction product are t.l.c. and g.l.c. These techniques may also be used to monitor the progress of a reaction for which optimum conditions are uncertain, as may be the case when an established published procedure is used as the basis for carrying out other preparations of a similar nature. In these cases the reaction is monitored by the periodic removal from the reaction mixture of test portions for suitable chromatographic study. Clearly the chromatographic behaviour of starting materials and, if possible, expected products, needs to be established prior to the commencement of the reaction. For t.l.c. this would include solvent and thin layer selection, a detection method, and an appraisal of sensitivity of detection with respect to the concentration of components in the reaction medium. For g.l.c. preliminary experiments would be required to select a suitable column and the appropriate operating conditions.

Notes are concise accounts of original research of a limited scope. They may also be preliminary reports of special significance. The material reported must be definitive and may not be published again later. Appropriate subjects for notes include improved procedures of wide applicability or interest, accounts of novel observations or of compounds of special interest, and development of new techniques. Notes are subject to the same editorial appraisal as full-length articles.

Rules of thumb, also known as heuristics, are statements of known facts. The word heuristics is derived from Greek, to discover or to invent, so these rules are known or discovered through use and practice but may not be able to be theoretically proven. In practice, they work and are most safely applied by engineers who are familiar with the topics. Such rules are of value for approximate design and preliminary cost estimation, and should provide even the inexperienced engineer with perspective and whereby the reasonableness of detailed and computer-aided design can be appraised quickly, especially on short notice, such as a conference. 

These rules are valuable for preliminary design and cost-estimating. Moreover, they provide perspective and a foundation whereby the reasonableness of detailed and computer-aided calculations can be appraised.

In Europe, particularly in Germany (Munich, Cologne, Berlin, Braunschweig etc.) preliminary comments, reports and reviews have been obtained. Women in Germany have paid much attention to the preparations of Sila-cosmetics that Russian women appraised five years ago, namely, Sila-stimulators , Valery , Fluffy eyelashes and the Baikal collection .
