 510  111. Magnetic-head requirements have become stricter as a result of the trend toward better frequency response, higher packing densities and lower tape speeds. Gaps of 0.0005 inch were considered small a few years ago, but today's highresolution heads have gaps five to ten times narrower. 112. The techniques are based on conventional technology which Fig. 5 exploits to implement the operations specified in Fig. 3. 113. Single tumor fragments of S-189 and Ca-755, weighing approximately 15-20mg., were implanted subcutaneously by trocar. Leukemic cells were inoculated intraperitoneally, with 0.1 ml. of diluted ascites fluid containing 105 L1210 leukemic cells. 114. If computers are ever to gain wide acceptance for process control they must be understood by the people who have to operate them. For this reason they should be kept as simple as possible. 115. Professor A. B. Pippard of Cambridge University, England, said theoretical problems have now been largely solved, but production barriers have to be surmounted before cryotrons and similar devices are put to practical use. 116. Programming a computer involves analysing the problem to be solved and a plan to solve it. 117. In the argon, nitrogen, and hydrogen plasmas used in the experiments, the plasma densities can be chosen around 10-9cm-3, nd Te is about 50.000° K. 118. In the steam engine the fuel burns comparatively slowly, e heat being used to generate steam. 119. The increase due to endotoxin averaged 18 per cent and anged from 6 to 46 per cent. Within the ranges studied, 1 to 8 x 10-6 gm/ml endotoxin and 10 to 50 per cent blood, there appeared to be no correlation between the concentrations of these materials and the magnitude of the augmentation by endotoxin. 120. It is in the area of equation solution that computers are invaluable. 510 |
