Changes Modifications

Lower level of engineering changes, modifications and concessions. 

Document changes/modifications are reviewed and approved by the [design department], which has access to all pertinent background information upon which to base its review and approval. 

Specific modifications of proteins result from adding a selected reagent to the pure protein or crude protein-rich material. This may be done in the course of a fundamental study in protein chemistry or as a step in the production of a bulk protein product for practical purposes. The same chemical modification can be useful in both processes. For example, enzyme chemists use charge-changing modifications to dissociate oligomeric proteins to their monomer components, while the same modifications are proposed as a means of solubilizing yeast proteins to permit their extraction for use in foods (11). This chapter is concerned mainly with the many types of intended modifications. 

Evolutionary designs based on proven technology demonstrated in practice, incorporating some improvements, but no substantial changes, modifications, or novel features. These designs are fundamentally similar to the latest models operating or under construction, and are also perceived in this way. In principle, they are available for construction without the need for plant demonstration.

During formation of MMCs various thermodynamic side efiects driven by a thermodynamically favoured terms can occur. This includes conformational changes, modification of functional groups and also macrochain breakage. Examples of conformational changes are chain transformation in poly(oxyethylene)-transition metal complexes [61,62], double helix model of poly(oxyethylene)-alkali metal ion complexes [63], conformational modifications of poly(2-vinylpyridine) or poly(amidoamines) during complex formation [64,65], and others. Important to mention here is that chain destruction can occur in type I polymers during their formation [3,66,67]. 

At the bottom a porous alumina ceramic acts as a diaphragm which forms electrolytic junction with the studied medium (Fig. 5.2.2a). In a slightly changed modification (Fig. 5.2.2b) the bottom of the cylinder is filled with an additional solid salt mixture which plays a role of a bridge electrolyte. 

RDP 5.01 has a provision for an independent multi-disciplined review board chaired by the Reactor Engineering Department. It is the task of this board (per paragraph 4.1.7.5) to provide this review. This task applies to "Project" level Modifications. Lower level "Operating Expense" projects are handled by the requirements of DMP 3.01. These Design Changes/Modifications are of a much smaller scope than those handled by RDP 5.01 (less than 50K).
