I have absolutely no idea what is being said here, but congratulations to newly minted PhD, Jeremy Stewart MacLeod.

Dr McLeod focused on the nucleation and growth kinetics of alpha lactose monohydrate. Lactose represents about one-third of the solids in cows' milk, and is recovered using crystallisation.
A model has been produced that can predict the changing concentration profile as lactose crystallises from an industrial solution. The primary nucleation of alpha lactose monohydrate was investigated, including identifying the changing relationship as lactose nucleation moves from being dominated by the heterogeneous mechanism to homogenous mechanism.
The effect of mixing was studied using a Rushton turbine and a Venturi to agitate the system. Increasing agitation increased the frequency of activated molecular collisions, but the critical nucleus size remained constant. A strong correlation was found, for both mixing systems, between the nucleation rate and the frequency of vortex shredding.
