This BBC article has a photograph of a clock (manufactured by the New England Clock Company - see History of Connecticut industry) where the face is divided both into the conventional twelve hours, and 32 smaller units. Does this time system have a name, and is there any more information out there about it? The Hexadecimal time system of John W. Nystrom divided the day into 16 hours, so the numbers read from the clock in question are four times the Nystrom value - it's therefore probably not an implementation of that system.

If we ignore diplomatic issues, is it possible to drive from the Alaskan mainland (whether Cape Prince of Wales or somewhere else) to the Russian mainland (again, either Cape Dezhnev or somewhere else)? Bering Strait crossing talks only about proposals to build a road or railroad that crosses the strait completely; I'm wondering whether the winter ice is typically thick enough and consistent enough that one could drive a land vehicle such as a truck or snowmobile, or whether one would be restricted to using a boat or aircraft.

One of my nostrils is always blocked, it switches but it's constantly either one of the other. Is that normal? 2.103.12.92 ( talk) 03:49, 28 March 2016 (UTC)
How many types of neuron cells do exist? I'm confused because According to the BRS gross anatomy (8th edition, p.6) there are three types (1. unipolar, also pseudo-unipolar. 2. bi-polar. 3. multi-polar) while according to the Moore anatomy book (7th edition. p.46) there are 2 types of neurons (multipolar and pseudounipolar) 93.126.95.68 ( talk) 03:49, 28 March 2016 (UTC)

I'm on a commercial R&D team where most of my colleagues are skeptical of any experimental process that is too "academic" -- still, we really want to increase average** particle size after magnetic particles linked to streptavidin bind to protein-functionalized-biotin conjugates, which doesn't appear to be really affected by pH (we have to stay within pH 5 to 9), and gets worse (smaller) with increasing ionic strength. So currently we're running optimization experiments by changing the temperature of the buffer during the biotin-streptavidin binding process.
To me, the obvious thing to do would be to obtain "double biotin" -- a covalent linker with biotin on both ends. We would only have to dope at around 0.1 to 2% ratio (per equivalent of "mono" functionalized and free biotin we're using) to get controlled increases in particle size, so the cost increase would be marginal. When I look up "dual biotin" I keep getting double biotin that is attached to some sort of nucleotide, which is pointlessly expensive because we have no use for the nucleotide. What is the right keyword to get a double biotin linker that *doesn't* have any nucleotide in it? Basically, if I can find a double linker that's cheap enough, then I might persuade my team (always bottom-line-minded) to try my idea.
** I really think we should be using the median as a useful marker of particle size to account for outliers, based on my previous experience with population statistics, but my team still thinks the mean is just good but sigh

According to budesonide: "The wholesale price for an inhaler containing 200 doses is about 5 to 7 USD as of 2014.[11] As of 2015 the cost for a typical month of medication in the United States is 100 to 200 USD"
Where do the $95-$193 go to? Couldn't a lab just offer it for $9.5-$19.30? Wouldn't US resident who need this medicine for treating a chronicle condition be better off traveling abroad to buy it? -- Llaanngg ( talk) 23:34, 28 March 2016 (UTC)
So while again this isn't legal advice, if you're lucky you may be allowed to import 3 months when coming back. Perhaps you'll even be allowed to import 3 months every 3 months. Even with usage 2 times a day, this will probably only be a single inhaler. If you need more than 2 doses a day, perhaps you'll get away with 2. So at most perhaps you're saying around $380. More likely $190.
If you live right next to the Canadian or Mexican border (and Mexican may bring additional safety concerns) perhaps it'll be worth the cost including your time spent (maybe a passport if you wouldn't have one otherwise). If you live far and need to either drive long distance or fly, it's unlikely to be worth it. And you have to hope you'd really be allowed to do it regularly, particularly if you were only gone for an hour or two. Even more so if you're trying to import 2 regardless of whether you use enough for this to be 3 months supply.
