Tail flick apparatus is an analgesia meter and is helpful in determining
pain sensitivity accurately and reproducibly in rats and mice. The instrument
has a shutter controlled lamp as a heat source. Activation of an intense light
beam to the tail through opening of the shutter results in a discomfort at some
point when the animal will flick its tail out of the beam. The photo detector
detects the tail motion. The total time elapsed between shutter opening and
animal's reaction is displayed on an easily read display. Data can be printed
directly or may be collected via RS-232 port. If you need more information, please
provide your street address. I will be happy to send you more information about
Tail flick apparatus.

I,m working on a project in school that deals with the question of
current trends in research.  I decided to look at current trends in the
use ofreptiles and amphibians for research.  I need this question answered
by somebody who has some authority on this issue, i.e. a herpetologist:
        What are the current trends in herpetological research
	and for	what reasons could they be accounted for?
Any answer to this question would be greatly appreciated!!  You can e-mail
the response to: oasis@mail.bcpl.lib.md.us
	Thank you for your time!	Timothy Thate 

A low cost data acquisition system is available which plugs directly into 
the serial port of your PC to measure such parameters as temperature, pH, 
pressure, strain, level, flow rate, light intensity, and viscosity.  Unit 
has 8 independent channels for simultaneous monitoring and recording.  
Data can be displayed in either tabular or graphic format.  Monitor comes 
complete with software program for DOS or Windows.  For further details 
contact Lazar Research Labs., Inc. at service@lazarlab.com or by fax at 
1-213-931-1434 or in the U.S. at 1-800-824-2066. Or see the Lazar web 
site at http://www.lazarlab.com

The National Academy Press, the publisher of the National Academy of
Sciences, National Academy of Engineering,  National Research Council, 
Institute of Medicine, has put 1000 science, engineering, and health
books on-line in their entirety free for the reading. You can find them
in the "Reading Room" section of the site.  The URL is:

This is a great resource, so be sure to check it out.

This is a call for any information, advise, help, collaboration
or selling offer.
For the reason explained bellow, I need a CH2 (polyethylene)
target depletted in Deuterium (99.999 % pure proton, at least)
and about 0.2 mg/(square cm) thick. 
It's quite easy to get either CD2 target or pure H2 gas, but,
up to now, nobody has been able to provide us with a pure CH2
target. Does someone know how to produce some?
We are actually measuring (p,gamma) reactions cross section
using radioactive beams. So we always have to work in 
reverse kinematic. We usually use CH2 target but the
natural deuterium in it induces a significant contamination.
Indeed, althought there is only 1 D atom per 10000 protons,
the cross section for (d,n) reaction processing by 
nuclear interaction and thus being far larger, the number
of counts comming from deuterium and from protons are
roughly the same. This makes data analysis very difficult,
especially when we are dealing with very low cross-section
and low beam currents. A CH2 target depletted in deuterium 
would be of huge help. 
Thank you,
