 491  131. Readings of about 50 test quanties on the line will be taken by the data logger and recorded every 20 minutes. Whenever test readings fall outside predetermined limits, the data logger will scan and record readings every 2 minutes until the values fall back into line. 132. On the whole, high-volatile coals, when stored for normal periods, do not suffer greatly, so far as the coking properties are concerned, whereas low voltage coals frequently give trouble through heating and deterioration during storage. 133. In this type of circuit, a low impedance path must be provided between cathode and earth at the second harmonic frequency if the efficiency is to be kept high. 134. The usual procedure when operating the machine is to select the next channel after each convolution of the tape to provide one long programme. Alternatively, any channel may be selected at any time if there are separate items of interest or one channel can be repeated continuously. 135. The unique property of DMBA in damaging adrenal is due to the fact that it alone among the hydrocarbons tested possesses the necessary geometry vis-a-vis the inner adrenal cortex. Thesteric factor assumes primary importance in DMBA-induced adrenal damage. 136. The output of the receiver in each channel is sent to a p.r.f. multiplier that multiplies the p.r.f. by a factor of either 3 or 8 (fig- 2). 137. Hart and Heroux observed that mice exposed to cold increased their oxygen consumption by sevenfold without appreciable change in the blood acid level, whereas running mice with a threefold to fivefold increase in oxygen consumption had pronounced elevations in lactate. 138. In what follows, the biochemical alterations are a used as a basis for discussion of possible mechanisms involved in 4 separate processes: (a) cessation of production of infective virus, (b) inhibition of mitosis, (c) production of cell damage, and (d) viral interference. 139. The required tolerances in alfa, beta, gamma, and delta for the measurement of height, speed and direction are tabulated in figure 3 together with a fourth row showing the tolerances which will satisfy all requirements together. 491 |
