Notes on Diffusion
These summarize methods for solving the diffusion equation. 1 Parabolic equations The diffusion equation is ∂φ ∂t = ∂ ∂x k ∂φ ∂x (1) This can describe thermal diffusion (for example, as part of the energy equation in compressible flow), species/mass diffusion for multispecies flows, or the viscous terms in incompressible flows. In this form, the diffusion coefficient (or conductivity), k, can b...

متن کاملSome notes on distributions
Formally, distributions are usually defined as continuous linear functions on a certain topological vector space of “test functions”. However, it is not surprising that useful mathematical objects such as distributions also have a natural, concrete description. We shall start from this viewpoint, and later explain the abstraction to topological vector spaces, and explain why the latter is impor...

investigate its toxicity to the rat. They noted that animals dying after sulphaguanidine showed goitres which on microscopical section were found to be due to hyperplasia and were practically free from colloid. The same effect was produced more or less by other sulpha drugs such as sulphadiazine and sulphapyridine, and Richter and Clisby (1942) showed that other sulphur compounds, notably thiou...
