There were wide scale reports of authorities using chains and locks to seal individual dwellings on apartment buildings by chaining the metal gates closed. If you look at pictures from the field hospitals that they built you'll also note that there were metal grills on the windows as well. Although given what we are seeing here with people refusing to isolate and going out I don't necessarily blame them.


Where do hospitals get their O2 supply from out of curiosity? Do they buy it from one of the major gas suppliers like praxair or airliquide and store it in the back as GOX/LOX or can it also be produced on site?


In the past they had large tanks of liquid O2.

More recently, many have a large oxygen concentrator machine on site which just takes it from the air.


Smear some alcohol on your forehead before the check, the phase change as it evaporates will drastically decrease the local temperature where it's applied.


You can also pick up a flightaware dongle, they have extra hardware inside of them that lets you pick up aircraft a bit further out/with more information. Benefit if you pick up one of those normal sdr kits from nooelec is that it comes with antennas. Easiest way to start is to take one of the antenna and trim it down to 14cm and stick the magnetic base on the roof of a car.


The 5% is quoted further in the article for overall grid waste. The per mile basis is purely there to compare why higher voltages for the Samer power lead to less waste.


Wait what,holy shit this changes everything. Always thought those were just random manufacturer marks on smt resistors.


Geotech is a bitch. Soils aren't homogenous and vary a lot in both composition and characteristics. There are multiple types of TBMs that are designed to operate under very specific conditions, for example a soft rock/soil TBM excavates through different mechanisms than a hard rock TBM. One of the big problems in any excavation is you have no idea what's actually down there until you start working in it. The underlying material can differ a lot over very short distances. You can very easily be minding your own business driving the TBM and run into a transition that will straight up mess you up. Combine that with all the previous mentioned stuff and you get a lot of cost overruns and time overruns. But yea, subsurface is a bitch.


Great answer, but I also want to add:

Even if you had ideal conditions or an amazing new TBM that goes through any material, you're still dealing with a machine that scrapes at rocks for miles on end. The parts that do the digging need constant replacement, underground, on the inconvenient side of the boring machine, and even if you did the actual digging faster that'd mean repairing it even more often.


I’m not disagreeing with you (I know nothing about geotechnical), but I was thinking the bottleneck is all the bureaucracy and infrastructure factors, which don’t have mechanically scalable solutions. I’m assuming tunneling through Las Vegas is much different than tunneling in NYC or SF or even LA.


I'm not sure if this will be great or I'm being punked.


PB goes kind of well with meat, as do peanut sauces in Asian cuisine. I get the same vibe out of it but only eat organic PB, not the processed garbage which has the texture of liquid plastic.


I'd add that development is also pretty foolproof since there are charts with precise times and concentrations for every known film and developer combo. There's also stand development which is actually fool proof.


Althought as a Montrealer I am really unhappy that the C-series is now called the A220, I was very happy when Bombardier basically bitch slapped Boeing by getting Airbus to buy it and make it in the US.


It was hilarious to watch the Airbus licensing, but Bombardier also got the raw end of the deal - with the corner they were backed into they're going to end up seeing a lot less revenue off that model then they had planned.


> they're going to end up seeing a lot less revenue off that model then they had planned

Per unit. Lifetime revenues could likely be higher given the heft of Airbus’ marketing machine.

Agree, however, that it compounds Boeing’s image as a distracted company.
