I only had one manual redirect link (I rarely enable JS).

And I only got the Abstract. Did you get more?

You can guess anything you like.

I like v in units of fathoms / microfortnight.

I was able to download the PDF without JS.

Hmmm... Interesting. The link you provided redirects to https://www.sciencedirect.com/scienc...94576518306398 (via a 302 Moved Temporarily HTTP response from the server).

And on that page I see a "Download PDF" link, which appears to only be active if you have Javascript enabled.

Maybe my IP has been encoded in the URL parameters so it might not work for others. Anyhow, now I try the link and I see "Purchase PDF" instead of "Download PDF", so it appears to be tracking IP addresses or something, and now I have burned my allotment of free access for some time period.

One solar neutrino detector (the Sudbury Neutrino Observatory) is in Sudbury, Ontario, deep, deep underground in a nickel mine. The locale shields the heavy-water detector from cosmic rays, which would otherwise swamp the neutrinos.

Been there, toured that, during a two-day visit, 6800 feet underground (during a nickel miner strike and a blizzard). It's home to the world's lowest and smallest sewage treatment plant, which they nevertheless must supplement with dog food to sustain it. Also the lowest clean room. Inside another clean room. SNO at one point had a large fraction of the available D2O in its detector, and managed to return all but a tiny tiny fraction after they were done with the heavy water phase and salt phase of their experiment. The engineer that designed and ran the water handling and purification system was quite proud of that. The system was also equipped with industrial sized UV water sterilizers as I recall. https://sno.phy.queensu.ca/

The trip was in preparation for design of the early water Cherenkov PMT version of DUNE. http://www.dunescience.org/ (Subsequently switched to liquid Argon and wire chambers for superior resolution.) A site visit to the Sanford mine site in preparation for DUNE was "only" to the 4150 level, except for an elevator ride down to 4800 to look down the tunnel, since the mine rehabilitation crew had not sufficiently stabilized the lower levels yet then to allow visitors to go into the 4800 level tunnels where the DUNE experiment far detector is being constructed. Over the century plus of mine operation, the rock had slowly flowed enough that in some places the narrow gauge ore car rail tracks that had initially been level had a sideways tilt of several degrees between rails.

Likewise. However, my first try ended with an error message because, in addition to having javascript disabled, I also had cookies disabled. I enabled cookies and tried again. Two manual redirects later, I was looking at the pdf.

Hayabusa latest image. couldn't find the space mission thread. It is at less than 125km now, going toward orbit (around a 8 face asteroid) at a staggering pace: 0.84 m/s. thats a bit more than 41H.

A spin-off from one of Rogue's posts, above. This sounds like a way to possible improvement, but my ingrained pessimism doesn't believe a word of it.

“From my experience, optimism is both a personality trait and a product of our environment,” says Karol Ward, LCSW, a licensed psychotherapist. “From an early age, babies and children pick up the emotional vibes in their homes. If the atmosphere is relaxed and loving, children blossom even if they innately have a tendency towards anxiety. But if the home environment is tense and filled with dysfunction, optimism is one of the first things to go. It's hard to be emotionally open and hopeful when that is not being modeled for you by your caretakers.”
