Hi folks - Here is the Friday Element Quiz Answer. Sorry for the long 
delay as I was out on business travel:

The Question:

This element has low ductility and high reactivity to air resulting in 
limited industrial uses. The largest use of this element is in the 
electronics industry in resistors and in hybrid integrated circuits. This 
element is used as a catalyst in the petroleum refining industry. 
Additions of this element to Titanium piping result in a significant 
corrosion resistance improvement for sour gas oil well applications. What 
element is being described?

The Answer:

The element is Ruthenium (Ru). Ruthenium is a member of the platinum group 
metals (PGMs). PGMs are some of the least abundant elements in the Earth's 
crust but have a number of unique characteristics. Ru is the least costly 
of the PGMs and is used extensively by the electronics industry in 
resistors, integrated circuits, Ta capacitors and computer hard disks. The 
Russian scientist Karl Ernst Claus discovered Ru in 1844.


The winner of this quiz is Denny Fritz of SAIC. A number of the other PGMs 
elements were suggested so many folks were on the right track in their 
sleuthing. Clumpy and his cousin Kloumpios will fire up their John Deere 
tractors and head for Indiana to work for Denny. I saw them putting chains 
on the back tires so this weekend's late winter snow storm won't stop them 
from traveling. Kloumpios seemed extremely unhappy about the snow but was 
determined to not let it interfere with their travel.

So far Clumpy and Kloumpios have:

Week 1 Lamar Young, SCS Coatings
- accomplished nothing (drank lots of coffee)

Week 2 Bev Christian, RIM
- conducted REACH material testing

Week 3 Drew Meyer, Benchmark Electronics Inc.
- Solderability testing and mowed the lawn

Week 4 Ian Fox, Goodrich
- had an epic journey of travel

Week 4 Gary Ferrari, Garrick Global
- unknown

Week 5 Fredrick Miller, Astrolab
- unknown

Week 6 David Nelson, Raytheon

Week 11 Dick Krug of Sparton Corporation
- assisted with AS9100 quality management systems requirements audit

Week 12 Steve Creswick of Balanced Enterprise Solutions
- Acted as Steve's "go fer" due to a broken leg!

Week 13 Gebhard Neifer, Delphi
- conducted a plasma pre treatment Taguchi DOE for a sealing process

Week 14 Bev Christian, RIM
- assisted with a tin pest investigation/test

Week 15 Bev Christian, RIM
 - assisted Bev shoveling snow

Week 16 David Bealer of Waatchfire Signs
 - unknown

Week 17 Brian Ellis, rumored to be retired
 - assisted with rewiring the house, had a tractor accident and found his 
cousin Kloumpios

Week 18 Denny Fritz, SAIC
 - assisted with tin whisker inspection/examinations
