Bimetallic corrosion of nickel-iron alloys may be of significance in welding operations. Ni-45 Fe alloys are used as filler materials in the welding of cast irons but the favourable area relationship of weld metal to base plate... 

Linlc effect in most atmospheres, except marine. Effects in sea-water anti marine atmospheres depend on surface area relationships. 

A detailed discussion of galvanic corrosion between dissimilar metals in contact in a corrosive environment has been given in Section 1.7, but in the case of coating discontinuities the effect of the anode/cathode area relationship and the nature of any corrosion products formed at small discontinuities may modify any choice made on strict considerations of general galvanic corrosion theory based on the potentials of the coating and substrate in the environment under consideration.

Mixtures of N-(a-methylbenzyl) stearamides with both stearoyltyrosine and stearoyltryptophan methyl esters show no discrimination in their pressure-area relationships at 35°C, regardless of the surface pressure to which the films are compressed (Fig. 34). The Yl/A curves for homo- and hetero-chiral pairs are exactly coincident. 

A word of caution from the authors The peak height and peak area are not interchangeable quantities. Consider for example how the height-to-area relationship depends on the resolving power of the mass analyzer or the response time of the detector.

If the amount of internal standard which was added to the sample is known, the concentration of the unknown amino acid can be determined using peak area relationships. These calculations must take the various response factors into account.

Dosage-surface area relationships In general, about 2 g of a topical product is required to cover the scalp, face, or hand 3 g to cover an arm 4 g to cover a leg and 30 to 60 g to cover the entire body. 

In an investigation of the spin-density (voidage) and spin-lattice relaxation time maps of many pellets, it was found that it was the heterogeneity in pore size, as characterized by the fractal dimension of the Ti map, that was consistent between images of pellets drawn from the same batch 58). The fractal dimensional of these images identifies a constant perimeter-area relationship for clusters of pixels of... 

To calculate monomer composition, these chemical shift assignments must follow peak area relationships deduced from isolated, paired, and > paired structures. 

Using these area relationships the equations in Table II were written to use the measured peak areas from a copolymer of vinyl chloride to calculate monomer compositions. The equations also provide checks on internal consistency of the spectra. 

Lacey next developed an important concept of the silt-factor-area relationship of a channel. Following Kennedy s formula and defining a regime channel" as a channel whose bed-silt and also self-silted side berms are nearly stable, self-derived, and long continued, then for two channels having the same mean velocities...

The dynamics of the relationship between gas supply, demand, and production can result in changing inter-area relationships with the passage of time. For this reason production projections based on an area-by-area approach do not have much validity beyond 5 years. Beyond that time span, estimates of the production available from a given reserve base are probably best made on a national basis.
