Powell-Sabin splines are C-continuous quadratic splines defined on an arbitrary triangulation. Their construction is based on a particular split of each triangle in the triangulation into six smaller triangles. In this article we give an overview of the properties of Powell-Sabin splines in the context of computer aided geometric design. These splines can be represented in a compact normalized ...

962142. 43 In this more recent work, McGinnis and Rappaport cite Powell to instruct us on the interpretive conventions of the founding generation. Id. at 8 (citing Powell, supra note 39). And Powell at least provides McGinnis and Rappaport some useful support when he announces: "Although the Philadelphia framers did not discuss in detail how they intended their end product to be interpreted, th...

A combination of emetine hydrochloride with chloroquine yields better results than either drug alone in the treatment of amoebic liver abscess in adults (Wilmot, Powell, and Adams, 1959). A similar combination of dehydroemetine with chloroquine is equally satisfactory (Wilmot, Powell, MacLeod, and Elsdon-Dew, 1964; Powell, Wilmot, MacLeod, and Elsdon-Dew, 1967). Dehydroemetine is claimed to be ...
