Dave,
Love those firewalls. The boys will help review some environmental testing for explosive atmosphere, Sand & Dust, Humidity and Salt Fog at a local supplier. When they get bored with that they can help patch the roof over my head that might have a developed a leak during the winter. After that they can relax and go fishing in the bay or ocean near my house.
Have a great weekend.
Regards,
Tom

Subject: [TN] Element Quiz Answer
Here is the Element Quiz Question:
The Question:
This element is a metal that is almost impossible to machine as it is neither ductile or mallable. It is the most corrosive-resistant metal known. It is used to make instrumentation that has to withstand high temperatures without breaking down. One of its isotopes is used for Xray assessment of metal castings for flaws. The element also has found extensive use in Xray telescopes and unmanned spacecraft. Which element is being described?
The Answer:
The element in Iridium (Ir)! Iridium becomes more brittle upon cooling so it is either worked in a hot state or using powder metallurgy techniques. A 60nm layer of Ir is used on the mirrors of the Chandra X-ray Observatory as it provided the best x-ray reflecting characteristics. Iridium has extensive use as the containment shell for the plutonium fuel source for spacecraft radioisotope thermoelectric generators used on Voyager, Cassini, Galileo, etc. Iridium is found in asteroids and meteors which has allowed scientists a window into Earth/asteroid impacts as a layer of Ir can be found in the geologic record.
The winner of the quiz is Tom Carroll, Boeing and he will get the services of Clumpy and Kloumpios for the week. Leland and Tom both provided the correct answer but the Rockwell Collins firewall had Tom submitting his answer first (which was totally opposite of what the TechNet time stamp was). Sorry Leland, apparent the Collins firewall tried to lose your response or scramble the electrons.
So far Clumpy and Kloumpios have done the following:

Week 16 John Maxwell
- Picked Clumpy and Kloumpios at Dulles with the usual grousing about long flights. Because this is their second visit I reminded them of their first visit when the exhausted my collection of single malt scotch and found the keys for my lawn mower. The neighbors had not forgotten them terrifying neighborhood dogs and making unusual patterns in their lawns.
The lads understood and went to work clean up my documents and standards.
We had snow on Tuesday and they pitched in with the neighbors clearing drives and side walks. On Wed I took them to the Manassas Bull Run civil war battle field so they could understand our civil war and our history better. Thursday when work was done we visited a couple of cider vineyards and wineries. They enjoyed the Jefferson style hard cider very much. After we were done on Friday off to a distillery for a tasting and lunch. Then off to the airport for their next adventure. Perfect gentlemen and they seemed to enjoy the side trips.
Week 17 Leland Woodall
- The boys asked for an easy week, so I set them loose with their John Deeres. They performed a spring yard clean-up for the entire subdivision.
Everyone wanted to know who these little fellas were, and it evolved into a discussion about elements and TechNet. Don't think the neighbors will be asking me any more questions anytime soon...
Week 18 Leland Woodall
- The boys spent their weekend playing golf, and then enjoyed the NCAA tournament games. Since they were in NC, they rooted heavily for UNC, and their cheers were probably a deciding factor in the game. They were also quite curious as to how folks could grow to be so tall.
Week 19 Tom Carroll, Boeing
- assisted with ????
I hope everyone has a awesome week!
