The result was 105 ppb. This is insane when you consider that Flint's level was 20 ppb during the crisis.
The cold water should be zero, but I installed a lead filter to ensure this.
Lead testing is pretty cheap and there are usually a lot of labs around big cities. Highly recommend water testing even if you don't think you have the risk factors.
86 dB at 10kHz (ouch my ears)
This is not at all flat and the implementation suggests it has low gain at lower frequencies. Without publishing of a full response curve this seems like nothing more than university PR.
Any comment from the authors of the study?
But I like the author's perspective, so I agree that we should at least consider the second price and prioritize purchase of items for which it is negative.
It's possible that society has imposed ridiculously stringent "requirements" for raising children (apparently families are buying a second washing machine just for their baby's clothes) that raising children responsibly is viewed as financially unachievable for most.
Probably not too many slumlords on HN, as evidenced by sibling comments.
"Employees are now discussing how best to respond, whether it be through another letter or legal action. About 10 people plan to resign or know others who will resign due to the hybrid policy, the report said"
Ten is more than one, but the article makes it sound like an exodus is impending.
That's an odd partnership. I'd expect they'd want to partner with a robotics company like Boston Dynamics.
>The concept has been in the works for well over two years
And all they have to show for it is a video? The article makes it sound like this is really happening but this is a very hard problem and they have nothing to show they've made any progress at all. Smells like marketing BS.
There's probably a lot of technical hurdles just to making a whole new type of engine. But they also need to design and build a new space plane. That's a brand new supersonic airframe.
There's a lot of engineering needed here. I hope we can see some indication of progress soon.
Ukraine is the only example where an autocrat was removed from power without the entire country falling into chaos. They were fortunate to lose control over just Crimea and the eastern zone.
The greater issue though, is that it seems the "majority" is now imposing their religious ideals on a "minority". That is an unacceptable violation of the basic right to religious freedom.
Sadly Turkey is far from the first country in the Middle East to do this. There's a guy in Saudi Arabia on death row because he admitted to being atheist on his blog / social media.
The fetus may be listening to the outside environment or hearing his or her mother talk, but if this was a prerequisite to the "specialness" of humans/primates you are referring to, then we would see significant differences in the immediate post-natal behaviour of congenitally deaf children. I haven't searched the literature for this topic, but I personally have never seen that mentioned.
An easier explanation is that these are genetically encoded. The ducks are a good example. Ducks hatched from eggs that are artificially incubated seem to have the same core instincts as those hatched from natural incubation.
That said, there are still important forms of communication between mother and child: chemicals. An extreme example is the disastrous and tragic affect of alcohol on fetal development.
Evidence?
I don't know if there's data showing those popups work, but they really ruin the user experience.
Personally I think it's stupid. Release the code under GPL and you'll save yourself a PR nightmare and future proof the company. Manufacturing and design of farm equipment is what keeps competition out, not software.
