Sorry, lots of topicsā¦.
Fundamental maths really. Convection in an inclined porous box. When the layer is infinite in length a linear instabilty analysis shows that the layer is stable after about 31 degrees from the horizontal. However, a finite length box is unstable to a much higher inclination if nonlinearities are allowed. No-one knows about the infinite box, but that is more complicated - that said I have a good idea of roughly how it goes. I am computing the maximum inclination for instability as a function of the Rayleigh number and aspect ratio of the box. Turns out to be more complicated than I first thought. I guess that someone has to do it, for its been the elephant in the room for decades. Use of a spectral scheme plus Newton-Raphson means quartic sums, but that is detail. You did ask! And I enjoy this more than planting flowers or do-it-yourself! Weird, I knowā¦.
The Stroke Assocation website immediately asks for cash. Oops, wrong emphasis. Yes, cash is important but secondary for us. Ideas, things to try are more important.
There are so many different things I do therapy-wise that I have to keep a record of it, otherwise things get missed.
Keep the blood pressure low. That has to be a higher priority than any Stroke Association. See the situation, assess it coolly and rationally, then act. Dispassionately. There are so many stresses anyway that we can do without self-generated ones!
Iāll be there this afternoon at 1.
