 518  193. It was thought that a semi-positive vertical flash mould would modify the flow pattern and eliminate the cracking. This was not so, it being found that although the mould design could do much to reduce the cracking, it could not completely eliminate it. 194. If relations (29), (28) and (27) for u, v, and w are studied, it will be discovered that all the boundary conditions at both ends of the cylinder cannot be satisfied. This difficulty is seen to arise from relations (21) and (22), causing Sy and Sz to be proportional rather than independent. 195. There may be some increase in random red cell destruction during this entire period, but the bulk of the red cells that are to be destroyed are probably removed from the circulation during the first several days after infusion of the antibody. 196. There are, however, exceptions, or features which do not fit such a simple picture, and it is these that are being viewed in the light of the recently discovered properties of viral nucleic acids. 197. Mere mechanization is muscular action, that is to say, our limbs can move without our having to use our brains. It is only when our brain controls our movement that these can be adjusted to changes in outside circumstances, and it is precisely this element of control which the modern electronic computer introduces. 198. One would thus expect the second harmonic to grow along the beam in much the same way the voltage grows in time on a lossless resonant circuit which is excited by a signal at the resonant frequency. 199. Commercial nameplates — be they of anodized aluminum, etched aluminum, or just plain parer— are generally made through either screen or offset printing. 200. The chief power of a magnet to attract or repel is concentrated at certain poles — located at the ends of bar magnet — one being known as a north pole and the other as a south pole. 201.S-180 bearing Swiss mice will, on the average, lose slightly more than I gm. (in 8 days), even though their tumors may contribute a gram to their body weight. 202. It was on November 24,1831, that Faraday demonstrated to the Royal Society that an electric current can be produced in a coil of wire when a neighbouring electric current is made or broken. 518 |
