separate spillway shapes. The spillways considered included (a) one corresponding to the shape of the nappe produced by flow over a ventilated, sharp-crested weir, (b) one corresponding to the shape of the nappe produced by flow over a ventilated, sharp...

"An experimental study of an electric arc in crossed convective and magnetic fields has been made. An electric arc was established across a rectangular test section through which argon gas was flowing at approximately atmospheric pressure...

corresponding to a trace of the heavy component."--Page 3752....

The study described was propounded to determine if it is possible to provide a biophysical driving force that will stimulate the operator in repetitive tasks to work at a rhythm that is comfortable, yet more productive than the rhythm he would...

"To determine the potential of a spacecraft, an electric field meter is needed to measure the field at the surface and in the neighborhood of the craft. A search was made for field measuring methods which would not involve rapidly moving parts...

"During the summer of 1963 the authors used fixed-time interval pictures to study traffic characteristics on a short section of Highway 400, Ontario. The purpose of the study was to obtain density-flow relationships, particularly a flux plot...
