here, saved you a read:

The institute also said that Poland had one of the lowest shares of part time workers in the EU at just 6.2% – well below the bloc’s average of 17.7%.

not sure but excessive caffeine can definitely make it worse

i mean technically it’s possible, you can show someone lab i guess there’s nothing extremely dangerous, not sure how it works legally, but the process is rather boring and we’re talking about a place that stores literal tons of piss why would you go there

what kinda drug tests are we talking about here? i’m talking about the kind where you send piss sample and then get result, or in fact hundreds of results. you need to make sure all your paperwork is complete and lab is certified and so on because someone might say that results are legally invalid

the process is a bit more involved, samples need tracking and monitoring and storage and preparation, and if it’s like you describe then guy’s sketchy and won’t survive audit

to run drug tests you need six figure range machine (when new), maybe 5 euro worth of plastic (spe column, eppendorfs, pipette tips), couple ml of acetonitrile and maybe 5-7 min of machine time on average. it can run 24/7 and if you find anything you can do more detailed analysis. bro’s not earning shit, he’s paying down the machines (and maintenance)

e: no way i’m nerd-sniped this easily. you can get hplc-ms for 90ish grand, add milliq water purification system, solvent recycling system, lots of fridges, a couple of laptops and company server and various other equipment and we’re probably in 200k range, excluding lab building itself. then you’ll need, say, $5 of consumables per sample ($2 per spe cartridge), so we’re talking about $40 revenue minus material costs. wages: you’ll need something about four people to run this thing at full tilt, two lab workers, one (?) clerk, half time driver and half time it guy, if you pay everyone 15k/mo then you need to go through 100ish samples just to pay wages not counting rent utilities and debts. but you can probably run 200 per day per machine, 300 if pushing it, so the main constraint will be logistics. because most of lab is in place then adding another hplc/ms will be only 90k. 300 samples per day print 9k per day, if you can get these samples. that’s probably why he’s expanding

god forbid a man has hobbies

pigments are the least problem, and many are not dependent on oil, like titania. some might, like soot, but because we’re talking about japan, it’s likely they get it from chinese manufacturer, and chinese chemical industry relies on coal heavily. but it’s such a small part of it all, binder, solvent and the entire packaging are likely petroleum-derived or dependent so there’s close to zero savings here. not to mention fuel and fertilizer use in farming that led to that product

it’s such unbelievably petty corner cutting, the only value of it is in marketing

you know what would help them? switch to solar process heat, best time for it was decade ago, second best time is now (they’re using heavy fuel oil for heating something)

cap, that’s a marketing move. black ink still needs solvent and amount of it saved by using one pass instead of 3 is tiny, transport will take more

4-5V is state of the art and pushing it there or beyond that gets very tricky very quickly. pure water has electrochemical window of 1.23V, but you can go a bit over that because at low overvoltage water splitting is slow at most electrode materials. that’s why lead battery can have 2V per cell and will generate hydrogen when charged much over nominal voltage

storage of heat is also very cheap compared to some other options and can just be using ground around boreholes, especially considering that most of residential energy use is in form of heat. if you have a hill that you don’t need you can even put an artificial lake on top of it

there’s a speciality resin (that new material) in that battery. resins are nonrecyclable. i don’t think it can be 4x cheaper per kg than LiFePO4 battery because of that material

some of you people itt have never imagined that there could be something like a research dead end and it shows

use of water as a solvent limits maximum voltage

wanted to use water to get electricity anyway for a laugh? we have a tool for that: it’s called STEAM TURBINE

or you could go with sodium battery, or LiFePO4, or thermal energy storage at this scale. hell maybe even pumped hydro

just put butter in the toothpaste tube smh
