JOHN WESLEY POWELL

Revealing sparks: John Wesley and the religious utility of electrical healing.

In the eighteenth century, dramatic electrical performances were favourite entertainments for the upper classes, yet the therapeutic uses of electricity also reached the lower strata of society. This change in the social composition of electrical audiences attracted the attention of John Wesley, who became interested in the subject in the late 1740s. The paper analyses Wesley's involvement in t...

Pike, John Wesley 1,25-dihydroxyvitamin D: Hormonal Regulation of Biosynthesis and Purification of Its Intestinal Receptor

The renal biosynthesis of 1,25-dihydroxyvitamin D (l,25-(OH)2B) is known to be stringently regulated by extensive ionic and hormonal controls. Quantitation of this mineral regulating hormone by radio­ receptor assay has recently enabled a study of its influence and syn­ thetic control during physiological states of growth and reproduction. The data reveal that 1,25-(0H)̂ D is strikingly elevated...

This study compared various biased estimation and subset selection regression techniques over a wide range of realistic situations. In an attempt to make the results applicable to the class of all practical regression problems, the parameters relevant to a comparison of the techniques involved were varied systematically. An outline of the design follows. (1) The residual variance ((sigma)('2)) ...

A multivariate Powell-Sabin interpolant

We consider the problem of constructing a C1 piecewise quadratic interpolant, Q, to positional and gradient data defined at the vertices of a tessellation of n-simplices in IR. The key to the interpolation scheme is to appropriately subdivide each simplex to ensure that certain necessary geometric constraints are satisfied by the subdivision points. We establish these constraints using the Bern...
