Diffusion coefficients were determined for the chloroform-air
system at 50°C and for the methanol-air system at 55°C by the Arnold cell
technique. The effect of concentration was studied by varying the
concentration of the gas stream passing across the top of the Arnold
cell.
The chloroform-air system exhibited a strong...
This paper discussed the human electrocardiogram, the instrumentation
used to graphically record it, and the design and performance
of a specialized system for vector cardiography: the Vector Electrocardioscope
(VECS) System. The introduction reviews in considerable
detail the pertinent known physiology of the heart, especially the
electrophysiology responsible for the genesis...
