In the course of upgrading an existing Hansch-type dye laser system, a noticeable temperature dependence of the peak power and divergence angle was observed for a variety of dye solutions. Cooling the solution over a temperature range of ~ 20° C resulted in a maximum increase in the peak power of 70%, accompanied by as much as a 13% decrease in the(More)
This paper concerns the stresses on the flight crew in various phases of space flight missions and the ability of the crew to perform piloting-type tasks as well as other specific operations in the presence of these stresses. The mission phases include powered flight, free flight, space maneuvers, atmospheric entry, terminal phase, and surface operation.(More)
The liver extraction of indocyanine green in concentrations of 0.2 mg./kg. and 0.5 mg./kg. in women taking oral contraceptive (norethindrone 2 mg. with mestranol 0.1 mg., and norethindrone 1 mg. with mestranol 0.05 mg.) is reported. No major alteration was noted in the hepatic function with the plasma concentrations of the dye employed. The probability of(More)
