Hope you all are well. Penetrations????!!!!
Penetrations of DU military shells into tank side etc. walls????
What are you all thinking?????!!!!! Sorry, I must have been elsewhere
intellectually in the last
Penetrations are holes, voids in shielding walls at accelerators
Places where incident or produced radiation are not being shielded by the
primary shield walls.
For example, penetrations can be places where beam pipes pass through
For a reference, please see Cossairt's Accelerator Health Physics
(1993 and other times). See also Gollon and Awschalom "Design of
penetrations in hadron shields"
CERN report 71-16, Volume 2 (1971), also published in IEEE Trans. Nucl.
Sci. NS-18 (1971)
I do not have this reference.
Tanks????!!!! How cool. Abrams tanks????!!!! Tigers,
Sherman's, Panzers, etc.
The little sewing machine company (NJ) (Singer/Kearfott/Astronautics) I
inertial guidance systems and accelerometers for tank systems. The lower
part of a tank needs one
guidance system to tell one where the tank is with respect to the ground of
Some other kind of angular positioning system (or perhaps even a second
guidance system) is
needed to tell one what the position of the tank turret with respect to the
bottom section of the tank.
The turret system is physically connected to the bottom of the tank.
Tank side wall etc. thickness to prevent shell penetration, well, look it
up for the tank of interest.
Jane's Military guides (England), Popular Mechanics, Popular Science may be
sources of information
about such things and flying objects.
A while ago now, Popular Science and/or Popular Science had an
article on Hydrogen weapon
fundamental designs. I recently saw a TV show lately on fundamental
hydrogen weapon designs.
Cool. Testing in the South Pacific also. Bernie C., does Israel test its
weapons in deserts
Global Warming again... Well, we'll see if temperatures of the
globe become more average in the
next 5-10 years.
Dr. Long, if you have data from 1954 on, you might plot US or
global hot weather/cold
weather deaths (per million persons????) as a function of time. Highs in
such deaths would be
around 1954 and 1998. Lows in about 1976??? Is this the case???? This
would only be the case if you
believe what I say about Earth polar motion peaks in 1910, 1954, and 1998.
Long Counter --- a form of neutron detector.
Geiger-Mueller detector --- see Cossairt's book.
Don't pick on the Mueller's ---- they tend to strike back... Many
in Germany, Switzerland, Austria. Uh oh, I said the magic word,
Austria... Better go offline
Have a good week!!!!!
