I hadn't heard about the mind state thing until I went onto Wikipedia just now, but I've known I was allergic to Yellow #5 since early childhood. It brings on rapid asthma type symptoms. Also discovered around Halloween time when I ate a large number of orange cookies from the grocery store, that I'll break out in hives all over my body if I ingest enough of the stuff. Have made a point not to do that again.
We found about (about our son's allergy) on Halloween, too, when he was 5. He got an uncontrollable neurologic eye tic that persisted for about a week.
So far as I can tell this is basically an anecdote. She doesn't even try to back it up aside from vague mentions of "articles" that she found (no specific studies were mentioned). Why should we give any credence to this over any other random HN commenter?
"The Food Standards Agency today announced its decision to recommend to Ministers the phasing out of six colours in food and drink in the EU. These six colours - sunset yellow (E110), quinoline yellow (E104), carmoisine (E122), allura red (E129), tartrazine (E102) and ponceau 4R (E124) - had been shown to increase hyperactive behaviour of children in a study published by a University of Southampton research team in September 2007."
> Currently, NOVAS has three different editions, for C, Fortran, and Python.
I imagine the Python versions wraps one of the other two. But are the C and Fortran versions separate, or does one wrap the other? If not, how are they related? Parallel implementations kept in sync by hand? Used to check each other? Machine translated? Code-generated from an upstream definition?
My knowledge is a few years out of date (but I would be surprised if the situation is different now). The Fortran is the primary version, the C is a parallel implementation that follows the Fortran, and the Python wraps the C. Calculations from each are compared to each other as well as calculations produced by https://iausofa.org/
Is there a way to get air quality via an api in the US that doesn't require api keys? weather.gov is one example of what I'm sorta looking for. I have a shell script [1] that gets weather and solar radiation from free and open APIs. Adding in some sort of air quality index would be great.
Supporting higher pressures or higher flow rates through the same area is one way to scale up reverse osmosis, but it requires some serious engineering to do (from the discussion above, very nearly at the “controlling placement at the individual atom” level). Meanwhile another way to scale it up is just make more of these membranes that we know how to easily make, and have bigger areas of membrane.
Ignoring the "how impossible is it to drill 0.2nm holes in anything" conversation above for a moment, what do you get out of stainless steel? My gut tells me you're looking for something with more permanence, but even stainless steel seems like a bad choice for something whose job requires constant contact with salt water (ergo, rust)
