51.   This is known as heterogeneous nucleation and only affects the crystallization rate, not the spherulitic growth rate, at a given temperature.

52.   These grow unimpeded for a while but the leading edges eventually collide with others and growth rates are altered.

53.   The growth rate was established by flow cytometry and the morphological characteristics of the growing cells by electron microscopy.

54.   These objectives can be in quantitative terms eg.

55.   In this period the member states were experiencing lower growth rates, and higher unemployment than the USA and Japan.

56.   Fourth, the elimination of exchange rate uncertainty is likely to yield benefits in terms of higher growth rates of intra-union trade and investment.

58.   But such manipulation of the money supply growth rate is a source of inflationary pressures.

59.   However, there is no empirical evidence to suggest that exchange rate changes have a systematic or durable impact on productivity growth rates.

60.   So if that four and a half million was all incurred in the second half its underlying growth rate was something like sixty percent.
