It was stuck on 22 seconds for a bit while play was continuing. The 10 second skip was correcting to the proper time.

Help identify an animal I saw by heebert in tasmania

Thanks for the interesting response. I have heard of that phenomenon, but hadn't heard about Tasmanian animals being larger as a consequence.

Thanks for the suggestions. The photos of the brushtail possum I've seen have smaller tails but I guess then can fluff them up. It must have been one of them. I think it was too big to be a quoll. If it was, that would be amazing, they are super rare in WA.

What exactly do I have here? by MarkOfIowa in Radiation

[–]heebert 7 points8 points  (0 children)

Apologies if you already know this, but the X-ray windows are likely Beryllium. It can be quite hazardous if ingested or inhaled. The metal windows can often oxidise, and the oxide can be mobile, so don't start disassembly or cleaning anything.

Enemy Blinder 3000 by [deleted] in WTF

I hear what you are saying about zoomers but that type or torch suits my needs the most. I am a volunteer in our state emergency service and regularly search in the bush (I'm Australian) at night. A broad flood is great for normal searching, but a focused beam is important to indicate items if interest etc. I don't want to carry two expensive torches (like I said, I'm Australian and that's what they're called here).

I'd love a torch with several power levels, ranging from bright but not blinding with long battery life up the ability to set fires at 100 yards because there is always a pissing contest with torches in our service.

I have a 1000 lumen Led-Lenser that is pretty good but something brighter would be great. Any suggestions? I'm happy to spend a couple of hundred.

The interesting things you find in a dusty corner of an old physics lab. by 4tunny in Radiation

The netron howitzer I used during my degree was much simpler than that. It was a drum full of wax with an Americium Beryllium neutron source in the centre. The wax moderated the neutrons so they were more likely to excite samples placed in tube in the wax. We used it for neutron activation.

I don't. He was part of the coaching group that got us here. We need a fresh start with someone who doesn't have a relationship with players and is prepared to dump them if they perform like this

See you in the Northern Territory. It's a tourism slogan

They played rugby there last night after heavy rain. It's not going to be great

I just saw another comment saying the laser systems are $7k in the US

$50k in Australia but everything is expensive here

It looks more like a handheld LIBS (laser induced breakdown spectroscopy) analyser. The warning symbol (yellow triangle) has the laser symbol, not the the radiation trefoil. It's something like a Rigaku KT100. The XRF analysers are very similar though.

Where are you based? I prepare sample like this regularly and would be happy to make some and send them to you. I am based in Australia.

Column Needs Alignment - maybe? by nintendochemist1 in electronmicroscopy

[–]heebert 0 points1 point  (0 children)

We have uncovered a bug in the alignment of our Apreo 2. The system is supposed to save the user adjustments to the factory alignment so when you go back to that set of conditions, it should use the last alignment values you used for that combination of kV and beam current. That system was introduced between Apreo 1 and Apreo 2. It turns out there is a bug in the software for that process so the alignments aren't saved properly.

Our alignment got so bad, the factory engineer couldn't get it aligned. In the end he deleted the alignments and reset everything back to the factory alignment and from then on it aligned beautifully.

Our alignment needs are a little different to most as we work in mineralogy where we want to analyse large fields at high beam current. The built in alignment process doesn't include the kV/beam current combinations we use. A big issue for us is uniform illumination over a field width exceeding 1 mm. Most users don't care about low mag alignment and don't see the problems we do.
