Eroding demand = sick people dying without the medicine they need

I’m starting to understand why people starting burning down all the real estate in the book “Parable of the Sower. “

Shit article. Only source is: “The warning came from authorities in eastern Zhejiang province on WeChat over the weekend after a comedian referred to her allegedly abusive marriage in a performance that went viral on Chinese social media.” There is no link to the primary source of any ‘warning’

The sound is caused by ‘gradient coils’ that are being switched on and off at kHz frequency, which is in the audible range for humans. The sound is caused by those coils vibrating due to the interaction of the magnetic field with the electric current in the coils: they’re non magnetic but they still feel the ‘Lorentz force’. As far as calibration, there is a pre-scan step (which is one reason why MRIs can take awhile) used to optimize the RF settings to each patient. Patients come in many shapes and sizes so the settings have to be tuned to get a good image every time. I’m actually not sure of how often they need to be serviced, but it seems like the manufacturers are here checking on the machines pretty often!

I recently tried spreading the word to other MRI folks about the dangers of ‘magnetic eyelashes’, which i learned was a thing from my fiance. Kind of suprised we havent seen any incidents with those, thankfully.

like others are saying: I installed a second NVMe SSD and put Linux Mint on it. This was a very simple task, and it automatically setup a boot window so when I start the computer it gives me the option to pick Windows or Linux. Linux Mint has a software center where I selected and installed Steam w/ Proton (again, super easy to setup, lots of online instructions) and my games work just fine. I keep Windows just because I dont want to lose my access to the OS, but Linux is now my main.

It’s both! MRI magnets are electromagnets that are cooled down to 4 Kelvin using liquid helium. Once they reach those low temperatures, they become superconducting. This way, the magnet isn’t gobbling up tons of electricity to stay at the desired field strength. Instead, the liquid helium needs to be replenished occasionally to keep it at superconducting temperature. Source: I work with MRI scanners.

Its an electromagnet that they have cooled down to 4 Kelvin with liquid helium. They take time to ‘wind up’ aka ‘ramping up to the desired/max field strength capable of the magnet’. They do this slowly because the magnet itself can crack if done too quickly, and many components are still affected by the strong magnetic field due to Lorentz forces. Also many components may be classified as ‘non-magnetic’ but still have some small amount of magnetism and can move when subjected to the extremely high magnetic fields. So, if the magnet is ‘quenched’ (all the helium shot out through a tube in the roof) then that process occurs in reverse, VERY quickly, potentially destroying many things. So its not like ‘cutting the power’ because the power is stored around the magnet itself by supercooled components creating a superconducting situation. Nonetheless, in case of harm coming to a person, techs should absolutely hit the quench switch. Not sure what happened to allow this guy in that room though

Just going through comments spreading MRI information (source: I work with MRI scanners). Nothing is spinning inside the MRI machine. CT scanners have an internal spinning component, but MRIs do not.

I’m just going through the comments spreading MRI information (source: work with MRI scanners). There is no radiation danger from MRI.

From Article: ‘’'She made those comments on a Sunday morning appearance on CBS’s “Face the Nation with Margaret Brennan,” when Brennan asked her if she felt the city was prepared to handle another fire emergency without a permanent chief.

“No, no, I don’t think that [the lack of a permanent chief is] a problem at all,” Bass said. “Our interim fire chief has 40 years of experience. In fact, he had just recently retired. I called him in, out of retirement, during the fires. He was doing the emergency operation center. So he stepped in, didn’t miss a beat by taking over the fire department. And we are prepared. We do know that it’s fire season.” ‘’’

Shit article whose only cited source is “A research team led by energy policy experts at Chinese universities”

Had the exact same thoughts about Blindsight. I got Watts’ second book in that series and didn’t even make it halfway. I think you described it well how Watt’s seems to have profound topics to discuss, but drapes it in some bizarre sci-fi/fantasy trope-filled amalgamation. I can’t think of another one I’ve felt that way about, but you’ve posed an interesting question for sure.

“A person”. Every single person has genetic mutations that differentiate them from every other person. Now if their mutation happens to be wings or something, then I don’t know, ‘Bird-Person’ probably.

Hasan - I feel like different people have different pronunciations of it and I can’t keep track of which is for who.

Adding to what the others wrote, solar cells become less efficient at power conversion (light -> electricity) as the temp of the solar cell materials (semiconductors) increases. So the issues is how to get more photons to the semiconductor without heating it up.

Is there any sort of regularly scheduled review to try and catch construction projects that may now be in floodplains that weren’t designated as such when constructed?
