Here is the Element Quiz Question:

The Question:
Tools made of with a metal alloy containing this element do not create
sparks when they strike a steel surface. Due to this element's properties,
it has the best heat dissipation characteristics per unit weight. The
element was used to uncovered the existence of the neutron.  An early major
application of this element was in brakes for military airplanes because of
its exceptional ability to dissipate heat. This element is a p-type dopant
in III-V compound semiconductors. Which element is being described?

The Answer:
The element is Beryllium (Be)! Beryllium copper tools do not create sparks
when they strike a steel surface. Beryllium's high specific heat and
thermal conductivity make the metal with the best heat dissipation
characteristics per unit weight.  A sample of beryllium was bombarded with
alpha rays from the decay of radium in a 1932 experiment by James Chadwick
that uncovered the existence of the neutron. Beryllium is widely used in
materials such as GaAs and AlGaAs grown by molecular beam epitaxy. Acute
beryllium disease in the form of chemical pneumonitis was first reported in
Europe in 1933 and in the United States in 1943. A survey found that about
5% of workers in plants manufacturing fluorescent lamps in 1949 in the
United States had beryllium-related lung diseases.


The winner of the quiz is Ian Fox  and he will get the services of Clumpy
and Kloumpios for the week of January 1st. The boys will be spending Xmas
and the holidays with their families relaxing and having fun.


Doug and I would like to wish everyone a Merry Christmas, Happy New Year
and a joyous holiday season that we hope is filled with family and fun. The
TechNet community is a wonderful resource and we are privileged to be part
of a great community of folks who gracious with their time/talents.

Week 44 Russell Kido, Practical Components
- How good are they in basketball?  Maybe they can help my 8-year old
daughter in her practice and her game.  We will be having some warm
temperatures next week, in the 80F range so they can pack light.  They can
assist me in visiting customers, might have to take them to the beach or
Disneyland, finalize projects for year-end and keep my colleagues in line.  Can
I send them to my factory to assist in long lead-time delays on our
products? (They can play the good guy, bad guy)

Week 45 Leland Woodall
-You're a good guy, Frank.  I can use them both to help me prepare for
Christmas.  I'm so far behind it's not even funny!

Week 45 Frank Kimmey, VeriFone Inc
- Leland,  take 'em both, I have to travel next week and the boys can be a
pain when by themselves (like getting into mischief)

Week 46 Ian Fox
- assisted with ????


I hope everyone has a awesome week.
