Culture Condition. Fifteen-day-old embryos numbering 11 to 14 per litter were removed by Caesarean section (23) and placed in Dulbecco s modified Eagle s medium augmented with glucose (600 mg %), 0.23% sodium bicarbonate, 90 units/ml penicillin,...

Development of the theory of nucleation is the long-standing problem in the statistical physics. The kinetic approach to this problem was proposed by Zeldovich" . For the nucleation rate. 7. i.e. for the number of critical and supercritical embryos being formed in the unit volume per unit time at early stages of nucleation, he obtained the following expression... 

Here the nucleation barrier AO is the excess thermodynamic potential needed to form the critical embryo within the uniform metastable state, while the prefactor Jq is determined by the kinetic characteristics for the embryo diffusion in the space of its size a. Expressions for both AO and Jo given by Zeldovich include a number of phenomenological parameters. 

Later on Cahn and Hilliard presented some thermodynamic estimates for the nucleation of liquid in vapour. Values of AO and the composition profiles c(r) of the embryos have been estimated using the mean-field and gradient expansion approximations for the free energy functional F c(7 ). A number of qualitative features in variation... 

Application of Eqs. (21)-(27) to the calculations of the nucleation rates J for various alloy models revealed a number of interesting results, in particular, sharp dependence of J and embryo characteristics on the supersaturation, temperature, interaction radius, etc. These results will be described elsewhere.

Fertile chicken eggs, 10-12 days old, have been used as a convenient cell system in which to grow a number of human pathogenic viruses. Figure 3.7 shows that viruses generally have preferences for particular tissues within the embryo. Influenza viruses. 

These equations allow us to calculate both numbers of embryos being formed and the energy involved in their formation. Thus, the interface structure affects the rate of nuclei formed and the rate of transformation... 

In Nature, however, we always have a contiiinous distribution of particles. This means that we have all sizes, even those of fractional parentage, i.e.-18.56n, 18.57p, 18.58 p, etc. (supposing that we can measure 0.01 p differences). The reason for this is that the mecheuiisms for particle formation, i.e.- precipitation, embryo and nucleation growth, Ostwald ripening, and sintering, are random processes. Thus, while we may speak of the "statistical variation of diameters", and while we use whole numbers for the particle diameters, the actuality is that the diameters are fractional in nature. Very few particle-size" specialists seem to recognize this fact. Since the processes are random in nature, we can use statistics to describe the... 

Growth at the level of the organism is an increase in cell number, cell mass, extracellular mass, fluid content and other components of the body that result in an increase of body mass. The mammalian body has very different growth phases with different functions. The pre-implantation embryo does not grow, but only divides, fuelled by materials that were deposited in the egg before fertilization. After implantation there is very rapid cell division which is tightly coupled to cell differentiation in the process of gastrulation — the creation of the different lineages...
