Reference Management Software?

I am looking for some reference management software, preferably running
under MS Windows.

We have heard of DOS based packages called Ref Manager and Procite.
Are these packages also available under MS Windows?

We specifically want to be able to insert paper ID Numbers (or something
similar) into the paper and have them generate a list of references
for the paper based on the reference database contents.  Also the
abililty to search the database by keyword, contents, etc. is required.

Does anybody have experience with such packages, where they can be
purchased and how much they cost?

If you mail your messages to me directly, I will summarize the replies
for the net.

You can reach me at      mb…@uoguelph.ca

This message is being posted by a friend at an other address.

Thanks for your assistance.

Wanted PREAMP for PMT

We have an old Raman spec. instrument that has recently decided not to work.
We have also isolated the source of our grief as the pre-amplifier from the
photomultiplier tube.  Yet we cannot find a suitable replacement, the company
that used to make the pre-amp (Harshaw model NB-28) has gone out of business
(probably a long time ago).  If anyone knows about what happened to the company
, where we can get a new pre-ampor how to build a new one, I would appreciate
hearing from you.
Thank you,   Lorne Fell    email:  shurv…@qucdn.queensu.ca

The best source is U Washington Analytical Chem, Seattle. They have a
group called Center for Process Analytical Chem (CPAC)
that has lots of chemometric stuff.

They publish lots in Analytical Chem – look for James Callis or ABruce
Kowalski as authors. I do not know of any on the net.

Oh, Peter Jurs at Penn State was giving away some stuff they developed
for the PC. You might check with him.

Egyptian Science?

I am in the process of researching a book on late bronze age Egyptian
science. I’d like to know if there are any good reference books on
chemical processes known to and used by the Egyptians circa 1200 – 1400
BC. I am particularly interested in their knowledge and practices in
inorganic chemistry and metallurgy.

I’d like to know what the Egyptians knew regarding the following metals
and their compounds, how were they smelted, what were the byproducts of
their manufacture: lead, copper, tin, arsenic, silver and antimony. Did
I miss any important minerals?

I’d also like to know the chemistry and history of Natron, impure
Sodium Carbonate.

If there are no specific reference books (and I have not been able to
find any) who are the current authorities in these matters?

Thanks in advance,

Steve Glines

Re: Solvent for soot

    Try limonene.  It’s made from orange peels and is considered safe.
    It’s an excellent cutting solvent for soot.

universal indicators

Hi, I’m wondering if anyone has a list of the component indicators found
in a universal pH indicator.  Thanx for any info, and if you would like to
reply (Please!) send email rather than posting, because I don’t normally
read this usegroup.  Thank you.

Mat'l Safety Datasheet?

Greetings,
Does anyone know of an electronic form of the Materials Safety Data Sheet
published by the state of California?  (CD-ROM or on-line database
source)  This has to do with transporting hazardous materials, and
employees right to know (prop 65).  Thanks to all answers in advance.
