23f, hypermobile, suspected hEDS (waiting for my doctor appointment).
I have all my years had problems with my joints, but lately been a bit more annoyed with all the pain etc. when I write, crochet, carry bags, etc. my pointer finger tends to do as pictured. I can fix it if I violently shake my hand, but I get pain when this happens. Any help?
Do i have none/low/moderate/high dental crowding, do i have high/narrow palate?
Have an exam coming up and wondering a few things not clearly communicated in the lessons. *I may use some terms wrong as I have learned this in a different language
Concrete will be able to handle different pressures before breaking depending on the ratio between ingredients, is there any other reason than cost for not using the strongest concrete?
When mixing you have superplasticizers (SP), viscosity regulator (VR) and air introduser. Which makes it more fluid, less fluid, and put air in it. Why use both SP and VR if they do the opposite?
What to do if there is a problem with the concrete? For example if it can’t stand as much pressure as it needs? If it loses water too fast and cracks?
Any other tips? Thanks for any answers given, I really enjoyed concrete as a theme, but a few questions went unanswered and having people who know well help with any tips I may not realise is great
Most functions I can imagine a graph (ish how it should be atleas) for example f(x,y)=1/(1*x**2*y**2), f(x,y)=cos(sqrt(x**2+y**2)), etc. but how can I match less recognisable ones (cos or sun waves are easy to spot), like (x**2-y**2)**2?
Any tips welcome🥰
