Effect On Growth

(1) If B. coli be subcultured into another sample of the same medium when growing at full pace, it will continue to grow at the same pace.(2) If the maximum rate of growth be interrupted by a short application of cold, growth will recommence without lag on the temperature being raised. If the cold be long continued, lag will tend to reappear.(3) Differences in the size of inoculum have practically no effect on lag in the case of large inoculums, in the case of small ones, on the other hand, diminution of the seeding has the effect of lengthening lag, and this lengthening effect is more marked the smaller the seedings become.(4) Lowering the temperature lengthens the lag. The effect is very similar to the effect on growth.(5) The older a parent culture (within limits) the longer the lag.(6) The length of lag varies with the medium even if adaptation has been arranged for beforehand.(7) Heat-stable products in B. coli cultures on peptone water have, in the case of overnight cultures, but little effect on lag.(8) After washing the bacteria for two hours with saline in order to remove possible inhibiting agents, it was found that the lag, on subculture, still occurred and was indeed slightly longer.(9) If a peptone water culture of B. coli be centrifuged, it is found that the few bacteria remaining in the supernatant commence to grow again at a quick rate but not without a period of lag.

Indentation Process

This paper investigates the thrust exerted on a vessel as a result of axial rupture, which has not previously been examined theoretically or practically. A simple model is developed to predict the peak thrust when the breach is large, that is when the fracture is propagating with constant velocity and the maximum rate of separation of the free edges downstream of the fracture tip has been achieved. The model assumes that the depressurization process within the breach zone is dominated by the transverse rarefaction wave initiated by the arrival of the breach as it advances along the vessel. The prediction is compared with a measurement made during a burst test on a large air-pressurized steel vessel. A novel measurement technique employed an inverse Brinell hardness test, in which the indentation size was used to calculate back to the force that produced it. This was interpreted with the help of a finite element computer simulation of the indentation process.

Plasma Effects

Plasma effects on the emission of synchrotron radiation are investigated using a two-dimensional electromagnetic relativistic simulation code. Results are compared with those for a vacuum; it is found that the emission lies between the vacuum emission for nc and nc + 1 where nc is the critical harmonic for EM wave propagation (nc = ωp/Ω0).

Rate Of Growth

INTRODUCTIONIn the genus Laminaria the origin of the growth of the frond (blade, lamina) is known to be the meristematic transition zone between frond and stipe. Parke (1948) showed, by observing holes punched in the frond, that the fastest rate of growth in length in L. saccharina (L.) Lamour. was in the proximal 25 mm. However, during measurements of the rate of growth of fronds of plants of known age on previously cleared areas (Kain, 1976), it was noted that in L. hyperborea (Gunn.) Fosl. the maximum rate of elongation occurred at some distance from the transition zone. This led to an investigation of the whole pattern of growth, in terms of elongation, increase in area, decrease in thickness and change in cell size and numbers over the surface of the frond at different stages.

Rate Of Growth

Investigations have been carried out in this department in recent years with the object of establishing the minimum protein requirements of the bacon pig. The results were recently summarized in this Journal (Woodman & Evans, 1948). The minimum protein standards recorded in that communication are consistent with the attainment of the maximum rate of growth compatible with the net energy content of the diet. The basal foods employed consisted throughout of 2 parts of barley meal and 1 part of middlings (fine bran), together with a little lucerne meal and minerals. Briefly, it was found that such a diet, when supplemented with 7% of white-fish meal, supplied the minimum amount of digestible protein required for the quickest possible rate of growth between weaning and 90 lb. live weight, when the level of feeding was such as is shown in the feeding chart (see Table 7). It was also found unnecessary to include any protein concentrate in the diet beyond 90 lb. live weight to ensure the maximum rate of growth over this later period. The requirements were based on the results of statistically designed growth trials, and were confirmed by nitrogen-balance determinations carried out in metabolism crates. It was found that nitrogen retention was just as favourable on the basal diet supplemented with 7% of white-fish meal as when the protein level was increased by feeding higher amounts offish meal.
