1. A simple phosphate infusion technique was employed to produce a linear elevation of plasma phosphorus levels with time. Using this technique theoretical renal phosphorus threshold (TRPT) was determined from sixty-seven infusions performed in fifty subjects in order to evaluate this measure of the renal excretion of phosphorus. 2. Glomerular filtration rate (GFR) was determined from phosphate...

Changes in dispersion or concentration of pigment within melanophores of vertebrates have been studied chiefly by the use of tlie microscope, and as a scale of measurement the melanophore index of Slome and Hogben ('28) has been adopted widely. This system has the disadvantage of being arbitrary and incapable of detecting slight movements of pigment which may well prove to be significant. Of se...

Arabella believes that her cat, Glendower, wants to go out. Her belief has representational and semantic features. It is about Glendower; it represents him as wanting to go out, and it has truth conditions. Her belief also has causal and rationalizing powers. She opens the door because she believes Glendower wants to go out. If we think that Arabella and other believers are physical entities we...

Hierarchical terrain models describe a topographic surface at di erent levels of detail, providing a multiresolution representation as well as a data compression mechanism. In this paper, we consider the problem of computing the visibility map, with respect to a xed viewpoint, on a hierarchical triangle-based terrain model. This problem presents two aspects: the extraction of a visibility map a...
