Some methods of direct determination of the parameters of a two‐dimensional structural fault with horizontal plane faces, from the gravity profile caused by it, have been formulated in this paper. The upward continuation of the two‐dimensional gravity profile plays an important role in these methods. The determinations by these methods are unique for structures of the same type in the sense that no structure of the same type other than that arrived at by the proposed methods can give rise to the observed anomaly. The necessary coefficients for upward continuation of two‐dimensional gravity data and the theory involved in their determinations form the appendix of this paper.

Gravity Profile

In their paper, Paul et al. have outlined a useful method by which the parameters of a two‐dimensional fault can be directly determined from the gravity data. The upward continuation of the gravity profile over the fault plays a very important role in this method. The necessary coefficients for the upward continuation and the theory involved in their determination form the appendix of the paper. The equation (9) in the appendix is incorrect since for any positive integral values of m and n, the coefficients Q(m, n) become quite large and negative, which will never satisfy the relation (10). The correct equation (9) should be [Formula: see text]

Abstract This spectrophotometric method for the direct determination of potassium in serum or plasma is based on the selective complexing of potassium by a specific macrocyclic polyether, with the subsequent formation of an ion-pair with a colored anion. The colored anion is extracted into an organic solvent, clarified by centrifugation, and then measured at 415 nm. The absorbance of the chromogen varies linearly with [K+] to at least 15 mmol/L. Results of this colorimetric method (y) correlate well with the results obtained by a flame-photometric method (y = 1.04x - 0.22, r = 0.97, n = 81), with CVs ranging from 2 to 4%. We observed no interferences from lipemia, added bilirubin, or various electrolytes. We also evaluated the use of this reagent in a new automated blood analyzer developed by Abbott, a two-dimensional centrifugal system (Clin Chem 31:1457-1463, 1985). Potassium determined with this system (y) correlated well with results by flame photometry: y = 1.02x + 0.02 (r = 0.94, n = 168). With this system one can use whole-blood specimens in measuring potassium.
