IF that link is about fecal-transplant, to put a healthy biome into people,
THEN just taking a good pro-biotic, instead, puts a good microbiome into one ( cures diahrea in 2-ish hours ), if one takes it with a probiotic-supporting meal ( like one’s favorite diverse meal, including each of the kinds of food one eats, some starches, some proteins, etc… ), seems FAR saner, in my eyes.
The whole “you need a fecal-transplant procedure” thing is a scam, in my eyes, because pro-biotics provably work, after one’s gut has gotten borked ( by food-poisoning, by antibiotics, by whatever ), & it works in mere hours.
Repeatedly good pro-biotics have un-wrecked my gut, after things like food-poisoning ( & I’m a guy who’s racked-up 7+ years of outright-homelessness, so food-preservation isn’t always possible ).
Dad had been a medical-researcher: he taught me to think.
Getting the right diversity of microbes ( you need both Lactobacillus & Bifido strains, multiple of each ) in one’s gut doesn’t, in any way whatsoever, require any clinical-procedure.
It requires a good bottle of pro-biotics, of a good, trustworthy brand.
Doing the experiment is something that people can do on their own.

Forgot this stuff, sorry:
Aviation:
Boats:
Say one has reinforcement-fabric with graphite fiber going east-west & kevlar going north-south.
Then the next layer is with the graphite going north-south & the kevlar going east-west.
Now vacuum-infuse it, so resin spreads forces between all the fibers…
What happens when the temperature rises, in hot sun?
The kevlar SHRINKS. Kevlar has a NEGATIVE Coefficient-of-Thermal-Expansion ( CTE ), but graphite’s is close to zero, & epoxy’s is positive…
So, now your layup is stressing, because some fibers are shrinking, & others are not, & the matrix is expanding.
Worse, when you try flexing it, kevlar isn’t stiff, so NO flexing-force is going onto those fibers, ALL of the flexing-force is going onto the graphite.
But did you calculate your layup so the graphite fibers would be able to take all the flexing that your piece needs to bear?
If not, now it’ll break.
In composites, the stiffest fibers resisting flexing, are taking ALL of the stress of that flexing, until they break, then the next-stiffest are taking all the load.
Mixed reinforcement-fibers is IDIOCY, but you can buy many brands of differently colored aramid+carbon reinforcement-fabric, from many vendors.
It is Niu’s composite-airframes textbook that caused me to know that, & the industry is pushing snake-oil bling, instead.
The only 2 cases where mixed-reinforcement-fibers makes sense, are
Oh, & graphite-fiber’s just thinner, stiffer carbon, generally. Processed at a higher temperature.
There: hopefully I’ve given you enough so that you can compete against me better, in the future.
Salut, Namaste, & Kaizen, eh?
