 512  132. Biological methods of purifying water are given much attention to by our scientists. 133. The association of the disubstituted phosphine oxides is probably similar, and the shift of tile P — H stretching frequency can be interpreted as reflecting the change of electron affinity of the phosphorus atom. 134. Nowhere can we see such rapid progress as in computing technique. 135. Since the relationship between opalescense and cholesterol release is evidently profoundly influenced by extract concentration, the progress of the two induced changes in serum with time was systematically compared at several different concentrations of streptococcal extract. 136. Powers approaching 10 or more times greater than those now being achieved are forthcoming. 137. It is of importance to know the basic principles to be observed in the design and use of optical equipment. 138. We know the velocity of a particle to be continuously changing if this particle has a nonuniform motion. In each successive time interval the particle acquires some increment of velocity. 139. Human erythrocytes from donors with blood group typings A and AB treated with an adenovirus type 1 suspension exhibited the same decrease in agglutinability against the test viruses as did group 0 erythrocytes. 140. For two thousand years the basic laws of geometry offered by Greek scientist Euclid were considered to be indisputable. 141. The input signal will be taken to be small enough for the condition of equal fast and slow waves to be reached before the electron's orbits have become large enough to cause any significant departure from the small-signal theory. 142. Different gases might cause the currents to differ by altering the surface of the metal either by combinig with it, or by condensing on its surface. 143. Having obtained information as to the homogeneity and chromosome constitution of the low ploid stemline of PK1-2, we introduced chromosomal variants into the population by means of x-ray treatment. 512 |
