If it matters, I read that the screen can't be flipped out when ports are in use

Nikon UN power supply lamphouse PLUG

Does anyone know exactly what this plug is called and where I can purchase one? Once upon a time I knew but have forgotten.

Thanks in advance,

Re: Diatoms: Centric&Pennate Slide

Very nice. Look great to me. I wonder if Klaus Kemp is still making slides. Last time I spoke with him (via email) he wasn't.

Re: On Lockdown

Not that it's relevant but Intel Fab 42 has been going strong here in Chandler Az., 6-10's+ has been pretty typical for the last year but work is slowing down but not because of COVID. I'd think that a semiconductor fab is one of the safest places to work in a pandemic. Maybe a Level-4 biohazard fa...

Re: On Lockdown

A few of the items I was reading about mask. Of courses there are many more that I've read, even from the CDC site, some of which were concerning on the mask testing protocol. https://www.medpagetoday.com/infectiousdisease/infectioncontrol/16278#:~:text=At%20the%20Interscience%20Conference%20on,of%2...

Re: On Lockdown

... and that's my point. From what I've read (not Facebook) if airborne (note the if) particles can float for hours depending on particle size, just like particles do in a semiconductor clean room environment. If that's the case and COVID particles are smaller than 300nm, then even N95 type mask wit...

Re: On Lockdown

For starters I'm not in the 'wear no mask' group, nor am I virologist etc. I understand the main point for wearing a mask. Keep in mind that Fauci even said in a interview wearing a mask isn't that effective. I think COVID is airborne therefore floats in the air longer, is smaller due to particle de...

Re: On Lockdown

... well my 2 cents. I think expelled particles are dispersed by airborne and/or droplet transmission and the particle size can be a small as 50nm. I think the typical masks being worn by the general public are highly ineffective at stopping particles. Not only from the poor fit but the material bei...
