Requirements for Compatibility

Distance between dissimilar materials Degree of exposure to corrosive environment 

Relative sizes of anode to cathode, or of a contaminator to the affected material Conductivity of environment versus conductivity of materials Resistivity of environment versus resistivity of materials Temperature gradients and spread Fluid current strata, directions, and velocities 

Contents of cathodic metals or aggressive materials in liquid media or atmospheres Criticality of resultant failures 

Sources of DC stray currents and their conductive paths Development of corrosive fumes in specific conditions Nature of the effect - beneficial or detrimental, etc. 

Dissimilar metals in intimate contact or connected by conductive path, such as water, condensation, or electrolyte, should be applied only when the functional design renders this unavoidable. If the use of dissimilar metals is necessary, an attempt to select metals which form compatible couples or groups should be made. The Galvanic Corrosion Indicator published by the International Nickel Company Ltd. can be useM. Table 9.1 shows examples of other environments with different indicators.

With the progress in optical communications, there has been a corresponding demand for the use of polyimides in optical components. Table 15.1 summarizes the primary requirements for optical communication materials and the approach used in this work. Thermal stability above 300°C is required for compatibility with conventional 1C fabrication. Polyimides have sufficient thermal stability in addition to easy processability for this use.z...

The selection of extrinsic fluorescent probe is driven by the consideration of which biological macromolecule or lipid is to be labelled, the requirement for compatibility between the intended fluorescent probe (in terms of solubility in water, pH sensitivity and so on) and the properties of the molecule to be labelled. Also, choice of the fluorescent probe should be consistent with experimental objectives. For instance, FRET experiments require that extrinsic donor and acceptor fluorophores should be properly matched for their capacity to participate in the FRET effect (see Section 4.5.4).

Synthesis of monomers with protected functional groups in the periphery. The protection is required for compatibility with the polymerization conditions. 

Polarizers are another type of accessory that may have special requirements for compatibility with the spectrophotometer. Again the manufacturer s literature should be checked to be certain that the polarizer will be usable on the instrument, and has the desired frequency range. 

Retrofitting of masonry joints with mortar is a common intervention work of restoration projects. Before designing the mortar s composition, a systematic analysis of existing mortars is made to meet requirements for compatibility and a decision is made about strength demand and durability. The selected traditional type binding system, such as lime-pozzolan, may also include a small percentage of brick bust or cement and admixtures to meet the compatibility and... 

FORTRAN IV Language—Changes in the program may be required for compatibility with the particular computing system to be used. These are permitted provided that the altered program gives the results shown in Table 4 with the input data of Table 3. 

The computer subroutines for calculation of vapor-liquid equilibrium separations, including determination of bubble-point and dew-point temperatures and pressures, are described and listed in this Appendix. These are source routines written in American National Standard FORTRAN (FORTRAN IV), ANSI X3.9-1978, and, as such, should be compatible with most computer systems with FORTRAN IV compilers. Approximate storage requirements for these subroutines are given in Appendix J their execution times are strongly dependent on the separations being calculated but can be estimated (CDC 6400) from the times given for the thermodynamic subroutines they call (essentially all computation effort is in these thermodynamic subroutines). 

The basic requirements for the Mephisto model was satisfactory accuracy, that means prediction of amplitude, position and phase relation between the various signals, and short computation times, typically a few minutes for the simulation of a whole Cscan, compatible with an intensive use. These a priori contradictory characteristics have been contented by means of appropriate approximations based on physical considerations. 

It should be emphasized at this point that the basic requirements of compatibility and consistency of finite elements used in the discretization of the domain in a field problem cannot be arbitrarily violated. Therefore, application of the previously described classes of computational grids requires systematic data transfomiation procedures across interfaces involving discontinuity or overlapping. For example, by the use of specially designed mortar elements necessary communication between incompatible sections of a finite element grid can be established (Maday et ah, 1989).

A general requirement for LIMS analysis is that the material must be vacuum compatible and able to absorb UV laser radiation. With regard to the latter require-... 

Once the identity of the material is known, the literature can be consulted to determine potential reactions. At this point, incompatibility may be obvious. If not, then laboratory testing for compatibility is required. 

The fundamental analysis of a laminate can be explained, in principle, by use of a simple two-layered cross-ply laminate (a layer with fibers at 0° to the x-direction on top of an equal-thickness layer with fibers at 90° to the x-direction). We will analyze this laminate approximately by considering what conditions the two unbonded layers in Figure 4-3 must satisfy in order for the two layers to be bonded to form a laminate. Imagine that the layers are separate but are subjected to a load in the x-direction. The force is divided between the two layers such that the x-direction deformation of each layer is identical. That is, the laminae in a laminate must deform alike along the interface between the layers or else fracture must existl Accordingly, deformation compatibility of layers is a requirement for a laminate. Because of the equal x-direction deformation of each layer, the top (0°) layer has the most x-direction ress because it is stiffer than the bottom (90°) layer in the x-direction./ Trie x-direction stresses in the top and bottom layers can be shown to have the relation... 

Advantages of the Stille reaction include neutral conditions under which the reaction takes place, often with full retention of stereochemistry, and compatibility with nearly all functional groups thus eliminating additional steps required for protection and deprotection. Conversely, a highly undesirable drawback is the use of toxic tin compounds and the ensuing difficult removal of these from the reaction mixture. 

Deletion of the Cavl.l and Cav1.2 gene is not compatible with viable mouse pups [4, 5], The Cav1.2 channel is absolutely required for the contraction of the developing mouse heart after embryonal day 14. 

Our studies of the absorption, permeation, and extraction properties of containers produced from high nitrile barrier resins have demonstrated that they meet or surpass the basic criteria established for retention of taste and odor characteristics of carbonated soft drinks. Sensory tests, which can isolate and identify end results as well as integrate collective effects, have confirmed this judgement and have established the general compatibility of these containers with a variety of beverage products from a taste and odor standpoint. Furthermore, these materials have the excellent physical properties required for containers which will find wide use in food and beverage packaging.
