 492  140. Table 2 lists yields for several radiations. In this table g (H) denotes the sum of the radical-type reducing species whether it is the hydrogen atom, the solvated electron or some as yet unknown entity. Vields are slightly different in heavy water and depend somewhat on pH. 141. The blood was obtained from the marginal ear vein. Rabbits which failed to develop a leucopenia of less than 1000 cells per mm3 were given a second and occasionally a third injection of nitrogen mustard (3 to 7 mg) and were following in the same manner. 142. However, this must be achieved by straight-forward design rather than by resorting to «trick» circuits which make repeater performance unduly sensitive to component characteristics. 143. The formation of the indole is often accompanied by the production of much tar, but in other cases it takes place remarkably easily. Thus the phenylhydrazone of cyclohexanone gives an almost quantitative yield of tetrahydrocarbazole when boiled for a few seconds with glacial acetic acid. 144. The random distribution of large numbers of ferritin molecules throughout the basement membrane and the absence of visible channels or pathways suggests that the increased permeability of this layer in the neprotic animal is due to a fine, generalized defect. 145. Operation with a multiplication ratio of 4 times is similar to that for 8 times except that S1 connects VB to the third divider output instead of the fourth. 146. To some it appears that even the announcement of Oersted's discovery need not necessarily have led directly to the development of the electromagnet and electromagnetic telegraphy, for the contributions of Schweigger, Ampere, Arago, Sturgwon. Henry and Morse seemed essential additional contributions. 147. As a basis for our experiments, we have tentatively taken the view that agitations and depressions result from abnormalities in motivational and reward processes, agitation from pathological overactivity of reward processes, and depression from underactivity. 148. For loads such as a magnetron, for example, the behavior of the pulser with a linear load is not necessarily a good criterion. 492 |
