Darwin equation
WebThe generalized Darwin equations, which result from the A = 0 requirement, are for neutron transport in a mosaic crystal. The generalized Darwin equations are a set of homogeneous equations, which can be solved with applied boundary conditions, and yield solutions for the neutron number densities n τ ( r ) in the transmitted ( τ = 0) and ... WebNotice that when N is almost zero the quantity in brackets is almost equal to 1 (or K/K) and growth is close to exponential.When the population size is equal to the carrying capacity, or N = K, the quantity in brackets is equal to zero and growth is equal to zero.A graph of this equation (logistic growth) yields the S-shaped curve (Figure 19.5b).It is a more realistic …
