Dear netters!

I'm really glad to be able to send this post. It's the final action after
a (sometimes) very hard struggle for this, our beloved newsgroup.

Finally --- we made it!!!

SCI.CHEM.ORGANOMET is active now!!!

I want to thank all the people who made it possible to get this group
working. It was a great deal for me --- the first newsgroup creation in my
history --- and I don't think I'd have managed it without your help!

Well, that's it! 

And now --- keep this newsgroup alive, ladies and gentlemen.....

START POSTING!!!

Greetings, Hartwig Kuehbauch.

The acid would taste bitter (sour), but the ester shouldn't.  Essentially,
they made sort of a fat.  Why they would put this in a soft drink, is
beyond me, but I think you're right that it is for texture.

Yeah, this is some good advice .... after all, ethyl alcohol is a pretty 
nasty drug ... the LD-50 to effective dose ratio is low, the hepatotoxicity
is high, it can be highly addictive, it causes both impairment of judgement
*and* coordination, tends to make people act violently, ..... Just say no

Oh, or were you talking about some other drug? :-)

Hi!

Can someone explain to me the difference between Ab Initio and Semi-Empirical
modelling? 

The way I understand it: the former uses the exact Hamiltonian and an approx.
wave equation while the latter uses an approximate Hamiltinian (PM3, etc) and
an exact wave equation. What does that mean? Which is recommended for Cope
Rearrangements and why?

Also, what is a singlet, doublet and triplet state, as in multiplicity 1, 2, 3.

Thanks!

If I understand you correctly, you are looking to a book that will introduced

Martin, Y.C. "Quantitative Drug Design", Marcel Dekker, Inc., New York, 1978.

In general, look for literature articles by Leo Hansch of Pomona College.

Ok, let's say you do allow total phosphate concentration = [H3PO4] +
[H2PO4] + [HPO4] = 0.10 M ([PO4] negligible).  But, will we still need
water to dilute?  (Remember, the total volume must be one liter.)

I needed gold electrodes once so I spent $20 and bought a small gold piece
from a metal dealer and just pounded it into the proper shape. Pure gold is
very soft and malleable....perhaps you can do the same with platinum...

It seems quite adequate to use a linked-list to represent the

which each atom and bond are data types that can express some more

Well, this answer is more or less from Cecil Adams Stright Dope
column, but what is in those lamps is:
water and wax.
The wax is manufactured so that its density is nearly identical to
water, and so that a small amount of heat can cause tit to expand and
become less dense, and rise, and upon cooling, contract and
become more dense than water, and sink to the bottom.  A bit
of coloring in various places, and a light bulb to provide heat
and light, and voila.
Apparently maintaining the wax density is quite tricky, and the actual
ingredients seem to be proprietary...

Subject: Re: Alternative refrigerants
Date: Sun, 20 Dec 92 00:29:09 PST
Organization: The Portal System (TM)

With regard to refrigerants and alternatives to fluorocarbons, there
are many alternatives, though none combine the low flammability,
low toxicity, and chemical inertness of the various fluorocarbon products
(such as Freon).

The National Refrigeration Safety Code Group divides refrigerants
into three categories:  Group I (safest), Group II (toxic and somewhat
flammable), and Group III (very flammable).

Group I contains all of the fluorocarbons, plus methylene chloride
and carbon dioxide.  Methylene chloride has been used in some
home refrigerators and air conditioning equipment.  Carbon dioxide
is generally undesirable because of the high operating pressure it
requires, although it has seen some use on ships due to the small
physical size of the equipment.

Group II contains dichloroethylene, methyl formate, ethyl chloride,
sulfur dioxide, methyl chloride, and ammonia.  Methyl formate was
used in a line of GE home refrigerators many years ago.  Sulfur
dioxide once was the dominant technology for home refrigeration,
but has since disappeared.  It is very irritating to the lungs.
Ethyl chloride and methyl chloride have also been used in some
models, and have likewise disappeared.  Both gases are about as toxic
as carbon tetrachloride (i.e. not nice).  Ammonia was at one time
used in home refrigerators and is still commonly used, especially in
large plants like fish processing plants and for systems powered by
natural gas (used where electricity is not available).  If there is a
little water in the system, ammonia will attack copper, bronze, or
brass components.  It is very irritating to the lungs.

Group III contains butane, iso-butane, propane, ethane, ethylene,
and methane.  All of these gases are quite flammable, but well-
behaved with regard to toxicity, corrosiveness, and lubrication.
Isobutane has been used in home refrigerators.

Although Freon has been the dominant home refrigerant for many
years, it would not be a disaster to lose this technology.  It would be
like losing PCB electrical insulating oils was.  It was a nuisance, but
other oils were available that had similar properties.  Likewise, there
exist several refrigerants besides Freon which are acceptable
replacements for Freon.  Once Freon is eliminated, we might expect
a few deaths due to fire or toxic effects that we would not get
otherwise.  For example, a common refrigerator-related accident
is due to the use of a knife to defrost a freezer.  If the knife slips
and pierces the freezer coils, the refrigerant will be released.  Future
refrigerators may need to be more secure against this type of
accident.

Well, Schweppes Bitter drinks used to be bitter because of the quinine added to
them as a tribute to the swampier parts of the British Empire. Quinine is a
drug with a multitude of effects (or side-effects), best known as the classic
anti-malaria drug. It is fairly toxic (MLD about 1 gm) and, worse than that,
known to have caused lethal allergic or intolerance reactions in far smaller
doses.

While quinine in soft drinks may have been a useful trick to smuggle a malaria
prophylactic into the gin tonics of drunk colonial officers, it is hardly a
suitable flavour for todays soft drinks - stuff like tonic water and bitter
lemonades probably escaped from the drugstores into the bars during prohibition
and its "medical" applications of cocktails.

Anyway, in most countries quinine has been banned as a food indigrient, and
soft drink manufacturers are using less harmful bitter flavours.

True quinine tonic water (Schweppes Kenia still used to sell pretty strong
stuff some years ago...) has a strange blueish hue, which might be mimicked
with glycerol ester of wood rosin, to give quinine replacement tonics the
colour of the real stuff.

I can't quite believe that the opalescence would be missed in bitter lemon,
though...

	What of Walt Disney?  Why is his condition not publicized

Perhaps some bad publicity that the procedure has could be alleviated if
the cryonics industry didn't rely on outsiders to dispell rumors
about it.  And, besides, where did this Walt Disney stuff get started?
