 517  184. This suggests that adaptations, probably in the form of mutation-selection, can occur in the quasi-diploid components as well as in the components of higher ploidy which have been considered as being genetically more versatile by Levan. 185. This will happen if beryllia is heated above about 1,850 F in the presence of water vapor, or if small-enough particles are mechanically produced from the solid. 186. The data in Table 1 and results of other experiments involving tests for various host responses, while indicating that the quantity of lipid present in endotoxins did not parallel their host reactivity, were not considered conclusive since the content of bound lipid had been determined by only one method. 187. As the cells involved in maintaining such a set point might be expected to have some unusual metabolic response to temperature level, Hall, Grant and Field made a systematic study of the Q10 of the tissues of the mammalian hypotehalamus using the Warburg method to see if they could find such a relationship. 188. The first column gives the cavity made, the second referring to Fiq. 4 and indicating the position of the ferrite with respect to the ef field, the third column giving the orientation of the dc field. 189. In celestial mechanics, one of the basic problems is to determine orbits of planets, asteroids, comets and meteors. For instance, a recent determination of the orbits of the five outer planets is reported to have involved over twelve million arithmetic operations still within easy reach of a fast computer. 190. A simple modification of the basicplot of Fig. 3 permits this procedure to be applied to a crystal oscillator using the crystal in its series mode. 191. The satellite is in a 70 per cent sun-time orbit with the transmitter assembly located on the shadow side of the satellite, normal to the sun vector. This is a transient condition with the transmitter assembly never receiving direct solar energy, but receiving refleced solar radiation 70 per cent of the time. 192. In the event of any pair of bars not completing its normal full travel, the machine is automatically stopped so that remedial action can be taken. The standard feed mechanisms, which have a travel of 7 in., can be used either singly or in pairs, for two simultaneous movements at one station. 517 |
