Subject: [TN] Element Quiz Question



 The Question:

This element is one of the Rare Earth Elements (REEs) so like most of the

rare earths, it forms trivalent ions with fluorescent properties and is

used as phosphors in various applications. Researchers at Iowa Statue

University/Ames Laboratory are using compounds containing this

element investigating its giant magnetocaloric effect for magnetic

refrigeration near room temperature, which could provide significant

efficiency and environmental advantages over conventional refrigeration

methods. This element is also used in nuclear marine propulsion systems as

a burnable poison. What element is being described?







The winner of the quiz will get the services of Clumpy and Kloumpios for

the week.

Week 65  Frank Kimmey, VeriFone Inc

-  Since the boys are probably tired from all the work George made them do,

they can join me for the week at Sunset Beach on the Monterrey Bay. Pure

relaxation on vacation. Maybe they can convince the local raccoons to stay

out of my camp. We’ll have some great games of Cards Against Humanity with

them.



Week 66  Jerry Dengler, Pergamon Corp

- Good timing.  We just purchased another oven and I can use the help

getting ready to take delivery



Week 66 Leland Woodall

- assisted with ????



Week 67  Eray Canli,  ANDAR Electromechanical Systems

- While I am on leave, guys can spend whole week trying to tidy my

desktop...hope they can finish before I'm back!



Week 68  James Head

- It appears that Clumpy and Kloumpios brought the rain with them after

we've had several weeks of dry and hot weather. I've been keeping them busy

all week with some Orcad layout work with a brief excursion to take my two

year old daughter to Mini Professors to learn about friction whilst

constructing a hover craft out of an old CD, balloon and the top of a

washing up liquid bottle. I caught them trying to violate the second law of

thermodynamics but managed to stop them in time before they could give

Louise bad ideas.



Week 69 ????

- assisted with ????







I hope everyone has a awesome week!
