To clean the glassware I have been using the sink in the galley and we have an autoclave behind the biosafety hood. As far as reference books, I like the idea but the last time we had a bookshelf it wasn't really kept up and became a dumping ground for older underused textbooks. Down the line we might get one but I want to make the area more organized beforehand. [6/16/2017 5:43 PM] albertm0015239 No worries I'm just glad to help and thank you for letting me know. I have the simple distillation set up with just water right now.

The course is free for everyone to attend and all are invited to attend. The first class will be the 26th from 1:30 to 2:30 pm.

When you take the double helix DNA molecule, another enzyme (helicase) unwinds the helix so you have 2 template strands: the leading and lagging strand. Each strand has its own polymerase to synthesize a new whole DNA molecule [6/19/2017 2:15 PM] clone1018 Wait so you start with one strand, it replicates to two strands with each their own ability to replicate more times ?

[6/19/2017 5:22 PM] ashley_newland8586 I know absolutely nothing about optics. [6/19/2017 5:24 PM] slunchery need shelving, storage? [6/19/2017 5:24 PM] ashley_newland8586 We have some microscopes that were donated to us from UT. I know they need new light sources, but maybe see if we could replace the objectives in them?

They can't be stacked unless in a box and I don't want to put them back in the cardboard box they came in [6/19/2017 6:19 PM] ashley_newland8586 Where do you think we should put them [6/19/2017 6:19 PM] ashley_newland8586 As long as they are out of the way and I the science area I don't care [6/19/2017 6:19 PM] ashley_newland8586 Thank you for taking the time to clean them though ^.^ [6/19/2017 6:22 PM] ashley_newland8586 Feel free to use any of the drawers to store them if you think that's the best place.

The Q factor they're claiming is *thermal*, at the back of the process, and none of it was - or could be - converted to useful ends. While relevant for improving theoretical understanding of deuterium/tritium fusion, it doesn't mean we're suddenly 5-10 years from practical commercial fusion. Because that actual Q factor was almost certainly <0.01 accounting for all the inefficiencies in the laser pumps and other apparatus. [12/15/2022 10:06 AM] chadpursley Thank you for sharing that.
