Incompatible solutes

Administration of data. If PCs are selected and purchased on an individual basis without coordination, isolated and incompatible solutions will emerge. Information that is concentrated at the single computer system in the case of a centralized system, is distributed over many separated stations, perhaps on diskettes handled by various coworkers. The collection and administration of information that may be important to the operation of an organization is difficult to manage or impossible under such circumstances. 

A set of equations is inconsistent if two or more of the equations correspond to incompatible solutions. 

Two-Phase Aqueous Extraction. Liquid—Hquid extraction usually involves an aqueous phase and an organic phase, but systems having two or more aqueous phases can also be formed from solutions of mutually incompatible polymers such as poly(ethylene glycol) (PEG) or dextran. A system having as many as 18 aqueous phases in equiHbrium has been demonstrated (93). Two-phase aqueous extraction, particularly useful in purifying biological species such as proteins (qv) and enzymes, can also be carried out in combination with fermentation (qv) so that the fermentation product is extracted as it is formed (94). 

Care must be exercised in using sodium nitrite near other chemicals. It is incompatible with ammonium salts, thiocyanates, thiosulfates, and strong reducing agents. In acid solutions, sodium nitrite evolves toxic NO in the presence of secondary amines it can form nitrosamines which are suspected carcinogens. 

This solution assumes that the beams behave elastically and that all the energy dissipation is associated with the pullout process. Typically for rigid incompatible interfaces, this fracture energy is quite low, ca. 1-5 J/m [1,20,21,61,59]. 

Consider the incompatible A/B polymer interface shown in Fig. 16. In the absence of compatibilizers, the interface is very weak such that the strength can be described by the nail solution as [11... 

In general, these two targets are incompatible. Later, systematic techniques will be presented to enable the identifying an MOC solution and then minimizing the number of exchangers satisfying the MOC. 

The dipping solutions described in Part II of this book are usually less concentrated than the corresponding spray solutions. The solvents employed are specially chosen for their suitability to the special requirements of dipping solutions. Water, which on the one hand, can sit on the surface of RP plates and not penetrate them and, on the other hand, can cause disintegration of water-incompatible layers is usually replaced by alcohol or other lipophilic solvents. 

Wang and Chen [41] studied the compatibility problems of incompatible NBR-PVC blends. Poly(vinyl-idene chloride-covinyl chloride) is reported to act as an efficient interfacial agent. Blends of PVC, NBR, and the copolymer were prepared by the solution casting technique using THE as a solvent. Improvement in mechanical properties can be achieved in NBR-PVC blend by the addition of different types of rubbers [42]. Different rubbers include NR, styrene butadiene (SBR) and butadiene (BR). Replacement of a few percent of NBR by other rubbers will improve the mechanical properties and at the same time reduce the cost of the blend. 

Since the corrosion resistance of the high-silicon alloys depends upon the permanence and impermeability of a thin silica film on the surface of the metal, it is obvious that any reagent which can damage the film will cause accelerated corrosion of the metal. For this reason all solutions containing hydrofluoric acid must be regarded as incompatible with the alloys. 

The different food products discussed below illustrate compatibility/ incompatibility problems and solutions in flexible packaging. 

Nowadays economy and ecology render the reuse of the sulfite solution increasingly important. Normally the scrubber liquor is recovered as dilution water directly in the neutralization of sulfonation plant or in the slurry preparation unit of synthetic detergent plants. In some special cases, when the presence of sulfites is incompatible with the slurry composition, it is possible to install as optional a sulfite oxidation unit. This oxidation takes place with atmospheric air.
