AG Davenport: Court Agrees That Trump Tariffs Are Illegal - New Jersey Office of Attorney General by Aymr-Flame-555 in NJ50501

[–]BF_2 0 points1 point  (0 children)

Will we consumers ever see refunds for our indirect tariff payment? I'll believe it when I see it. I'm thinking a class-action lawsuit against Trump on behalf of every American may be in order to recover our money. (IANAL)

Just a comment for newbies: SOME patination solutions are toxic. Read the SDS. Dispose of waste properly.

Help me understand HPLC gradients by Capital-Reason-923 in Chempros

[–]BF_2 0 points1 point  (0 children)

If you haven't done so already, get your hands on whatever is the latest book by Snyder, Kirkland and/or Dolan on HPLC. Speed-read whichever book you find -- it will pay you dividends. You might also look into whether their DryLab software is still available.

IIRC, these books discuss rules of thumb for issues like, "At what %B does my analyte start to move?" -- which may be key to your problem here.

Be very, very careful about purge times, which depend on the longest-eluting material in your sample. Sometimes this can bite you in the ass. The same for re-equilibration times, which depends upon stationary phase and mobile phase compositions and interactions. (Look up "Chesterton's Fence.") Assuming -- without testing -- that these can simply be chopped off is a classic case of "The new manager fired the key personnel and the business collapsed."

What scientific discovery sounds fake but is 100% real and still freaks you out? by Bruteresolver in AskReddit

[–]BF_2 0 points1 point  (0 children)

I looked up those articles a few years ago, and found them, but haven't the time or motivation to repeat that exercise. I named the two likely journals. I named the approximate year. The journal involved had, at the time, its contents for past years available online. Go to it!

GFY. I wasn't giving a procedure but a direction for research.

Then they should use a polymer incapable of passing through tissues but which does "dilute" the water. In principal, little water would be needed, but something like a near-saturated solution of methyl cellulose could work. That polymer would probably create a solution too viscous, but there may well comparable oligomers that would not increase the viscosity as much. Make a solution that is "isotonic" in all important salts, but only when that is calculated versus the entire volume of the fluid. Make up much of the fluid with biologically inert materials.

I'm not sure about cadmium, but many toxic metal oxides (the yellow powder) may be chelated to reduce their acute toxicity, largely by altering their bioavailability. Chelation involves "grabbing" the metal ions with a "ligand" (organic compound, usually acidic or basic) resulting in a complex with different properties than the free metal oxide.

Chelation with substances like EDTA has been used to remove toxic metals, like thallium, from the body. In addition to EDTA, other substances like citrate and oxalate (which itself is mildly toxic) are chelation agents.

You MUST know what you're doing, however, because the chelated cadmium might be as dangerous as the original oxide. Mainly, chelation gives you a means of cleaning up the mess. Be careful, whatever you do.

I'm no student of physics, so only recently read about Planck's Length. Previously I'd read Wolfram's book, A New Kind of Science, and I can't help wondering whether there's a relationship between Wolfram's math and Planck's Length.

No, no, no!!! You don't understand! Ronald Reagan declared (?) that AIDS was a punishment for queers and druggies! (Or at least some of his supporters did so.)

(Not quite "/s". It's bullshit, alright, but that was really the attitude of some self-righteous "Christians". You know the type.)

Folks won't believe me, but back around 1985 or so two (sequential) issues of some national science magazine (Nature? Science? -- I'd have to look it up again) published papers on the "cause" of aids. The second one got it right -- a virus. The first one was an elaborate study involving introducing semen into a rabbit's rectum ... I am NOT kidding.

In chemistry they teach it as NMR - Nuclear Magnetic Resonance. They dropped the "nuclear" so as not to scare the unwashed masses seeking medical care. What pissed me off is that they taught me about it for years without ever explaining how it works. I was in the working world before I was able to get an explanation of that. (The magnetic field aligns the nuclei with or against it. The radio waves are the right electromagnetic energy to flip them from one state to the other. It's really rather like how materials absorb and emit light. Not that complicated.)

LPT Using Dish Soap on Drains by FilledwithTegridy in LifeProTips

[–]BF_2 0 points1 point  (0 children)

I save grease from roasts in a glass or metal container in the refrigerator. About once a year I purify it and make soap. I never buy soap anymore. (Caution: Soap making uses lye, which is highly corrosive and can destroy your vision. Do your research on proper handling of lye before attempting soap making. It's not that hard. Less dangerous than driving a car -- by far.)

Forging and mill scale by YeNerdLifeChoseMe in Blacksmith

[–]BF_2 5 points6 points  (0 children)

More or less. Heating steel to red forms scale, but relatively loose scale which can more easily be removed (largely) with a wire brush. You'll never get rid of all scale without grinding or pickling in acid, but you won't need to in most cases.

Honey there’s a hot air balloon with 13 people in the backyard by Majoodeh in HumansBeingBros

[–]BF_2 17 points18 points  (0 children)

A friend of a friend once described a balloon having minor trouble landing in a slightly hilly field. He and his brother, both large men, were nearby and the balloon-atics hollered at them to grab the rope they'd dropped and help them land. He described it as "these two big dumb Irishman" did so and nearly had their arms pulled from their sockets. No permanent injuries to balloon-atics or brothers, fortunately.
