Fancy_Breakfast posted:That sounds fatal. The "alignment" that the nuclei experience has to do with the complicated physics of nuclei and their spin state, it doesn't like physically align the molecules by moving them around. The nuclear spin state of your atoms is on a very different time and physical scale than the biochemical interactions making you live. Looking at the signals from the changes induced can identify types of atoms and bonds, basically.

cyberbug posted:CT scanners running at full speed are some of the more mad scientist contraptions out there https://www.youtube.com/watch?v=2CWpZKuy-NE I used to work for a place that built CT Scanners. I had no part of that side of the business. Our side was even more hosed up, but I won't even get into that because of various regulations, yada yada. But let's just say that if you have an option between using one or not, take that latter.

Think of it this way: there's a field right now that's exerting force on every single atom in your body, pushing all of them around. It's called gravity. A MRI machine, by comparison, can't even move your atoms. Just make them rotate or flip back and forth. And the atoms that actually do want to move from a magnetic field are held in place by all the rest of the atoms around them. Just like how your feet are perfectly adequate at stopping gravity from collapsing you into a pile of goo on the floor.

I have a degenerative back condition that required surgery a few years ago. I was sent for a CT ahead of the surgery and went to see my neurosurgeon for a pre-op appointment. Him: Why did you get a CT done? You had an MRI 3 months ago. Me: Your office sent me to get one. Him: Well, that was a waste. The MRI is fine. Me remembering how they warned me the CT raised my lifetime risk of cancer like 1.5%: Okay. At least insurance paid for all of it. Him: Good. Nice imaging, though. I will say this, having had a bunch of MRIs from various hockey injuries and things, the CT is paradise considering it takes like 3 minutes total vs 45-ish trying to sit completely still for the MRI.

Oh I get it, but unfortunately they're not completely interchangeable. "Funny" part is MRI's are usually a poo poo ton costlier so Hospitals like to use the because money. But if it's a soft tissue thing they are worth it...I guess. My comment about other options definitely wasn't geared toward an MRI, we built those too! My best advise is to never leave your house. All risks go way down at that point

CT's are usually quiet machines in comparison to MRI's. Something about MRI's scared me but it turns out CT's are the ones more likely to kill you. https://www.youtube.com/watch?v=8oI9YnhPNcQ

Yeah a CT is basically an ex-ray(see radiation) on steroids. An MRI, as the name implies, involves magnetic fields and radio waves, which apparently are quite noisy at large doses. schmug fucked around with this message at 18:57 on Sep 27, 2018 |

Cojawfee posted:Is that even a rental truck? No... The bridge height, marked on signs, was 3.4m which incidentally is the bridge height that I feared the most when I drove a delivery truck because it was also the registered height of my vehicle. Whether it would fit depended on a plethora of variables like my tires and cargo and the evenness of the pavement. The only way to know would be to test it real slow. I wouldn't take the risk. Here it looks like the truck fit under the old stone bridge deck but then bumped into the new bridge's structures. It may have been an old tried and trusted route that to the driver's surprise wasn't anymore.

Grundulum posted:What the hell was leaking out of it? And was this a reasonable use scenario (like, did the lack of resistance mean the blade spun faster than it was designed for)? Super-dense smoke. You can see it's smoke as it rolls off the table edge. You would generally expect your angle grinder to spin without completely melting, yes. The speed at which it is designed to spin is when it is like this, without load. HF's electric poo poo is just that, poo poo. Not made well with no QA, so sometimes you get this. There's also probably someone out there with this same make and model of grinder that has been working fine for a long time, it's just a real crapshoot.

POOL IS CLOSED posted:Sooo how OSHA is not having flashback arrestors on the tubes for an oxygen - acetylene welding setup? People used oxyacetylene rigs for a hundred years or more without flashback arrestors and only occasionally killed themselves horribly, so you're probably okay, just make sure you purge both lines before lighting the torch and kill the torch by turning off the oxygen first. BUT. Flashback arrestors are cheap, go buy one now. Turn that "occasionally" into a "never" today. If you want real oxyacetylene OSHA, go look up acetylene generators, which work by dumping calcium carbide into water. Real easy to splatter yourself with one of those. Sagebrush posted:
