Re: [ccp4bb] crystallisation and mosaicity

Hi Charlie, yes you are right, but I assumed if people see a cloud of condensed fog over their LN2 bath they should remove that by a) filling up the bowl completely e.g. some LN2 drips out of the bowl b) blow the fog away before you dip c) ask someone for advice In general I have observed

Charlie, The insulating gas cushion is due to the Leidenfrost effect ( http://en.wikipedia.org/wiki/Leidenfrost_effect). We discussed this somewhat in: J. Appl. Cryst. (2005). 38, 945-950 -Lokesh On Wed, Jun 4, 2008 at 8:11 PM, Charlie Bond [EMAIL PROTECTED] wrote: I seem to recall an

Re: [ccp4bb] Fwd: [ccp4bb] crystallisation and mosaicity

I think the important thing here is that liquid nitrogen in the lab tends to be exactly at its boiling point, since the temperature is maintained by continuously boiling off some of the N2. This means the only mechanism for heat absorption is through vaporization, depending on the latent heat of

Re: [ccp4bb] 3D model building without CRT monitor

There is a 20-inch (20-3D2W04) display that costs around $6000. For $13000 you get a 42-inch, so I guess the 52-inch that was introduced today will cost a lot. Vangelis On Jun 5, 2008, at 7:30 PM, Juergen Bosch wrote: Interesting! Their PDF says it works with OpenGL:

Hi: Just a related question. To measure MW of membrane proteins, the density of detergents needs to be matched by D2O/H2O and should be within 1.0 to 1.1. Anyone knows some literature that gives a list of detergents having suitable density? Unfornatatedly, the common ones like Foscholine

Has anyone tried a 3D DLP-TV? They have the input for a stereographics emitter. Probably too big for a desktop but at 50-72 they would work in a conference room. They range in price from $1900-3500. Here is the link for the SAMSUNG website http://product.samsung.com/dlp3d/index.html.
