I think the gentleman is looking for any organisations that hold 
congresses on the subject of TNT, and would also like to know if there 
are any future congresses coming up, and the names of those which have 
been held during the last 10 years.

This is calculated from the protein/fat/carbohydrate/alcohol content and
a standard formula.  It is very much affected by legal requirements (for
example, the same material can be either starch or fiber depending on what
test you use.  Starch is 4 calories per gram; fiber none.  Somebody generally
mandates what test to use).  The absolute best way to get more information 
is to call the Cooperative Extension Service (a division of USDA run through

The commercial "Cyalume" sticks use a peroxide reaction, but as far as I
can tell, the details are only written up in their patent.

These reactions are all outlined in the literature in detail. I do not
have the literature list (a friend 'lost' it for me) but you should
be able to dig around in your library's database and find what you need.
These are "chemiluminescent" reactions.


> Is it

Yes! Luminol is available from Aldrich and Aldrich-like companies. There
are other compounds you can get which will do the same thing in different
colors.

>Would it be cost effective?  

You mean as opposed to buying a bunch of Cyalume sticks? Probably not
the Luminol reaction (priced it out at one time) but if you investigate
making your own compounds, I think you'll find it is indeed possible.

Shoot, I wish I could remember the name of that book, "Chemiluminscent

I can do a quick search here for title and publisher.

Distribution: sci.chem
Organization: University of Regina, SK, Canada

I have read most of the arguments about the explosive gold dust. Is 
it possible that gold combines with O2 resulting explosion? Certainly not. As
pointed out by many guys, gold oxide releases O2 at high temperature. 
Is it possible that gold combines other gases in the air, such as N2,
CO2, etc? No, that sounds ridiculous. The conclusion seems clear: gold
dust is not explosive!

However, do we have to have a chemical reaction to have an explosion?
An explosion is resulted from a sudden release of enormous amount of
energy. The energy can be from chemical reaction, or it can be from
simply physical condensation. If the gold dust is so fine that 
its surface energy is very significant, explosion could happen. Of
course you won't see gold oxide being formed, you will see chunks of gold 
formed from the gold dust. Actually, most of the dust explosion are 
mainly due to the surface energy problem (at least ignited by the surface 
energy problem).

     I never said anything like that, but I understand how my posting
might have been misconstrued in this way.  I was objecting to the idea
of saving gold for jewelry.  If there are good reasons for saving gold
or for making a special effort to recover it, and I am sure that there
are, surely jewelry is not one of them.

     I think that David and I agree.  I was taking issue with the idea
of saving gold because of its "charm".  By all means, let's save gold
because of its technological utility.  On the other hand, if we do have
a real use for it, let's not be shy.  (Making good catalytic converters
is extremely important to our efforts to clean up the atmosphere.  It
should be a high priority.)  Since, as David mentioned in another part
of his post, so much gold goes into jewelry, we do have a large repository
of it in relatively pure form sitting right under our noses, not to
mention in our nations' vaults.  I either missed the point of Rajat's
posting, or David missed mine.

That's an excellent suggestion. I hadn't thought of that. After all,
the use of e.g. flammable solvents in the lab is quite common.

If that is what they are worried about, I would have liked them

It is my understanding that as soon as you start with any type of
liquid fuel you are automatically out of the 'model' rocket catagory -
since by definition a 'model rocket' uses only pre-manufactured motors
(among other things). Therefore, any regulations that are for model
rockets probably will not apply to your project.

You are getting involved in 'Amateur' rocketry which has a completely
different set of regs.

Where the line between 'model' and 'high power' rocketry is kind of
fuzzy (read: 'high power model rocketry'), and, as we just learned,
the FAA is now proposing a 'large model rocket' class, the definitions
between 'model' and 'amateur' rocketry is pretty well spelled out. 

Especally when dealing with the government, it will be important to
make the distinction clear.

The applicants should be eligible for a D.Phil degree, by holding a good
Honours or Masters degree. No specific experience of carbon dating is required,
as full training will be given.  The candidate's background should be in
science or archaeology, and experience in practical science would be advantage.

In addition to the Scholarship, the applicant will work as a technical
assistant for 10 hours a week in the Laboratory.  This position is
available for 3 years subject to progress.  The part-time technicians
position will carry a minimum salary of $NZ6,193.00 per annum, based on

I would like to get some perspective on the current
and future (5 years) uses of computers in undergraduate
chemistry education. I am a mathematician who is
involved with making plans for math and science
departments that may have a long term effect. There
is not any strong indication from the chemistry
faculty that computers are/will be important in the
lower division service courses. Computers are currently
used now and then in labs for data analysis.

Being interested in computer issues I am aware of the new
field of computational chemistry. I am also aware that 
dynamical systems like several coupled harmonic oscillators
can be simulated and visualized, since I have done so myself.
Do these developments have no impact on undergraduate 
chemistry?

I know what curriculum projects the NSF is supporting in
math, but not in chemistry. Are there innovative projects
requiring advanced workstations for teaching chemistry?

I know that chemists use Maple, Mathematica, Matlab. Will
these be demanded for use in the chemistry curriculum?

Should the chemistry dept want its majors to be using a
computer in their calculus classes? Should we expect the
chemistry faculty to ask for an introductory course in
Maple/Mathematica taught by the math dept?

I would appreciate the opinions and experience of those
who know more about these questions than I do. I will monitor
this newsgroup, but if you want to be sure I get your 
message, send it to me directly.

And try Chem Abstracts (60-70's?).  There's a whole bunch of papers and patents

in a relatively well stocked Chem Dept.  I did some of them for a course
