Final Engineering

Finally, engineered surfaces may contribute to the understanding of adhesion (172). Control of adhesion is essential to a large number of industrial processes and is often associated with various problems, but currendy (ca 1997) there is Htde if any understanding of how specific molecular ordering and interactions at the surface may affect adhesion.

Finally, engineering modeling studies for prediction of deactivation behavior are needed which consider quantitatively all of the chemical and rate processes involved in the commercial process. 

Detailed schematics, equipment specifications, and construction details of the various systems are developed during the final stages of project implementation. As demonstrated in Figure 6, several parameters are orchestrated simultaneously. Obviously, with this degree of detail, the project involves input from several disciplines. The final engineering phase includes development of the following ... 

In some cases, construction and startup are separate phases of a project and are not included in final engineering. In oil packaging projects, this is normally part of the final phase. Thus, concise definition and agreement on the contents of final schematics and specifications cannot be overestimated, as both system capability and overall project cost can be traced to this definition. 

The final engineering tests with the civilian mask offered some interesting problems which had not been encountered before. Prior to this test no item of like materials and like construction had been subjected to such severe environmental conditions at Dugway Proving Ground. The tests consisted of storing the masks for 9 weeks in chambers at —65°F. (arctic), +165°F. (desert), and -fll3°F. and maximum humidity (tropic). In addition, masks were stored for 3 weeks under each of these climatic conditions in succession (cyclic). Upon completion of this surveillance, the masks were compared with controls as to physical condition, gas life, and aerosol penetration. 

Action. The final engineering tests on the civilian protective masks CDV-805 have been completed. OCDM has initiated action for the final production studies on this mask. The Army Chemical Corps is acting as the OCDM agent in this study. When the study is completed this information will be made available to industry and distribution of the mask, through commercial channels, is planned. 

The putative structure of the BAR protease can be inferred from its sequence homology to chymosin (see Fig. 1.5 b Protein Data Bank entry ICMS). When the mutations that were found in the final engineered BAR variant are mapped onto this structure, approximately 50% of the mutations lie in or close to the substrate binding site of the protease, while the other 50% are found at distant sites in the protein. This distribution confirms that directed evolution processes efficiently generate mutations at relevant positions.

Because the designed part must satisly certain functional requirements, it is necessary to verily the suitability of the design before it is finalized. Engineering analyses such as kinematic analysis and heat transfer are carried out from the design. Finite element methods can be used, often directly from a design model. The more critical a product or part is, the more detailed an analysis needs to be conducted. 

Specimens for strength testing are often smaller than a final engineered component. Will the strength of the component be higher or lower than the test specimen ... 

Finally engineering judgment has to be exercised for categorizing observed component damage, which has an influence on the value of k in Eq. (9.34). For example a failure shortly after a repair points to unprofessional maintenance rather than to renewed failure.
