The utility of artificial potential functions is explored as a means of translating automatically a robot task description into a feedback control law to drive the robot actuators. A class of functions is sought which will guide a point robot amid any finite number of spherically bounded obstacles in Euclidean n-space toward an arbitrary destination point. By introducing a set of additional con...

The effect of deuterium oxide (D20) on the survival of mice inoculated with Ehr l ich ls mouse asc i tes tumor has been studied. Mice maintained on 25%and 30% D P drinking water showed an improved survival t ime of about 6 days whereas 40%DZO drinking water had no effect on survival t ime. The effect is interpreted i n t e r m s of inhibition of tumor cell division and systemic toxicity. t Ann ...

As a means of determining the risk of absorption of water contaminative phenolic compounds through the skin, the permeat ion of a number of phenols, all on the U.S. Environmental Protection Agency ' s list of priority pollutants, through hairless mouse skin has been studied, using in vitro diffusion cell methods. Experimentally determined permeability coefficients through intact skin and stratu...

A comparative study was made of two alternative methods for the clinical trea tmen t of occlusal pits and fissures in the early post-eruption state. Contralateral pairs of permanent first and second molars wore carefully selected so that one mo/ar couM be given a preventive treatment with pit and fissure soal~n t, while the paired molar surfaces were restored with amalgam.
