Funny, I just walked around my ICU and everything is connected via ethernet. Monitors (philips), ventilators (dragers) and of course the computers (windows). Even the dialysis (prismaflex) machines hook via ethernet.
The ultrasound has an ethernet cable attached as do the image intensifiers. The biochem lab also works over TCP.
Certainly nothing major in the hospital that I work in uses serial connections.
Maybe the older equipment used to use serial but given the amount of data shuttled around I don't think it would be feasible so use serial. Of course I can only draw experience from where I work, other hospitals may be different.
From a quick googling it seems that the reason that water tanks are illegal in the above states is not to do with affecting the local environment but more to do with the fact that it 'deprives' downstream users of their share.
I get the feel from the articles that downstream providers are farmers and not parched wildlife.
Interesting numbers, except the specific heat of water is 4.18 J/K/g. So you'd need a power output of 4.18W to heat 1 g of water through one kelvin.
Water has a massive specific heat when compared to many other compounds in nature.

Whether or not a molecule emits energy in the form of light has nothing to do with the number of atoms. It has to do with the energy levels of the electrons in the outer shell.
As the electrons fall back from their excited state they emit a photon of light at a particular wavelenght, related to the energy drop. If you have a small drop then the wavelength will be large, ie red or infra-red light. If you have a large drop then the wavelength will be smaller, ie green, blue, violet.
Don't forget that when hydrogen reacts it produces water was well 2H2 + O2 -> 2H2O, so you'll have your triatomic molecule you want.
The reason that corn brooms are used to detect flames is that the flame from a slow hydrogen leak is not very intense, made up almost exclusively with blue and violet photons. These are hard to see.

Hydrogen flames are very definitely visible. Depending on the ratio of fuel to oxidant (ie oxygen) the colour of the flame can range from a very faint blue to an intense orange.
I do a chemistry demonstration where I explode a balloon with either pure hydrogen or a stoichometric ratio of hydrogen and oxygen. The first explosion is just a puff of orange flame, the second is a bright flash of light and a tremendous explosion which has been known to shatter fluoro tubes at 10 metres.
This is the kind of attitude that is damaging to linux.
If you are trying to get a user to switch over one of the important things you can point out is that linux works like windows. You want that program, well just download it and install it. None of this screwing around trying to compile it, downloading a million different libraries trying to find the right one
Most desktop users and new switchers are just not interested in compiling a program to get it to run. They want it to "just work"(tm).
Very few people die from polio, it's the crippling deformities that make this disease so nasty.
Rickets is a disease of vitamin D deficiency. I'd like to see you try and vacinate against that. Plenty sun, calcium or phosphate is the trick to preventing this.
Ebola. To my knowledge there isn't a vaccine for this disease. Though while nasty doesn't tend to spread to far and thus other nasty disease are concentrated on.
Diseases that should be immunised against:
Measels
Mumps
Rubella
Pneumococcal
Hep A/B
Diptheria
And those are the ones that I can remember off the top of my head.
As a user of SciFinder Scholar I really don't think that ACS should be trying to draw a comparison between their product and google's scholar.
SciFinder is terrible. The UI is non-consistent with the standard windows suite, cf to google's wonderful UI. SciFinder is also ugly as a dog (a pug at that).
It's slow as a dog, cf to google's speed.
Tell it to save to results and all you get is unprintable ascii characters.
Performing a search is painful task with poor boolean support.
On the whole scifinder is poor product that I hope is supersceded with google's scholar.

A Commentary on 'The Hare and the Tortise'
In reality the hare would have beaten the pants off the tortise in a
race, rarely does slow and steady win the race. Instead it is the fast
hare capable of the leaps and bounds of modern thinking that will win
the race. This fable is told to encourage fat stupid children.

Finally someone found a good use for Fosters beer. It's certainly not good for drinking.
Although we do manage to sell it to the Americans and claim that it is beer, they seem to buy it.

Have a look at http://hyperphysics.phy-astr.gsu.edu/hbase/hyde.ht ml
to see the spectra of hydrogen. It's got some visible lines in it.
Here's a picture of a hydrogen flame, faint but visible. http://jchemed.chem.wisc.edu/JCESoft/CCA/CCA3/STIL LS/CLH/CLH/64JPG48/2.JPG

What happens when you end up in hospital and the poor intern can't find any veins because you've got no blood pressure.
That intern is going to dig around looking for vein where ever s/he can.
I've seen veins burst whilst canulars are being put in. It's an inevitable thing that happens during an emergancy session.
I'll bet much vaunted biometric scanner fails.
