Almost anything you add to copper will reduce the conductivity slightly- probably not enough to matter for signal lines. However, copper is relatively easy to refine. The thieves would just have to sell it to someone further back in the processing line. In the limit, they could sell it as copper ore. Sending it through the process that turns raw copper ore into pure copper would certainly remove any additives. You would cut the profit margins for the thieves and perhaps they would quit stealing copper. That leads you to two other questions. What would they do instead? also, how could you protect old copper. There's lots of it already in place.

"We know that Al tends to form amorphous oxide layer when exposed to atmosphere at room temperature." No we don't. I'm fairly sure I have read that the layer has a definite structure- albeit different to corundum. If my memory serves me well it's a defect rock salt structure.

I rather suspect that this thread is written by Victor Rajic. If I'm right then this thread shouldn't last any longer than the last one. http://www.scienceforums.net/topic/56009-telepathy-schizophrenia-god-mystery-of-my-life/page__p__597780__hl__%2Brajic+%2B__fromsearch__1#entry597780

Are minors who have sex with adults 'victims'? Yes.

I looked at this "That's a fine premise for a really good question, but I wonder what data (if any) supports the premise. Perhaps... if no one has compiled data to support or reject the assumption... we could do it ourselves. Norway (and specifically, its GDP) I see was given in that regard, but looking at the top few countries listed by GDP per capita, I see that a good deal of the top listings (4 of the top 6 for example) do legislate the death penalty which stands out as the most severe punishment." And I wondered why someone chose GDP as a measure of "development". Personally, I don't see any country with a death penalty as civilised. (I might accept that, in wartime , that would be different for some crimes). In any event, Qatar has a very high GDP and an attitude to human rights that, at the most positive, could be described as "better than some of its neighbours". The UAE isn't most people's idea of a well developed country either. http://gulfnews.com/news/gulf/uae/crime/women-get-jail-and-deportation-for-kissing-on-dubai-public-beach-1.106824 Money really isn't everything.

It all rather depends on the definition of temperature. The temperature of the active material in a laser is, from at least one point of view, negative. As it cools down it goes through an infinite temperature.

"heavy water is water with deuterium oxide in it" Not really, it is deuterium oxide. "Deuterium unfortunatelyis heavy hydrogen and can be quite dangerous to manufacture." Nor particularly. "In order to gainhigh-purity deuterium, electrolysis of heavy water with the D2O concentrationof more than 99% is usually used. " Not much help, sine the OP is trying to get heavy water, not use it up. So basically to getheavy water, you need to get a dustbin full of water, electrolysis the shizmout of it, and then on the... cathode you should get your deuterium. Once youhave this, you can add it to water to make purer heavy water." nope. " And heavy water isonly used in so far as to MAKE deuterium, which thanks to the paper below hasthe following applications:" No, D2O is used for plenty of things without conversion to D2. So, as I said, Unless and until Klein gets back here and explains what his first post meant there's not a lot of point in continuing this thread.

For a start, I would do it without the aid of a fairy tale.

If that law required a gas cylinder of SO2 to be labelled "Sulfur Dioxide" rather than with the English spelling would it show that they didn't know what they were talking about? Will they rename the dept of labour to enforce the rules?

Unless and until Klein gets back here and explains what his first post meant there's not a lot of point in continuing this thread.

That works so much better if you remember to put capital letters on English and Scots as well as at the start of the second sentence. Incidentally, I think I know what he meant to say. I'm just trying to work out what was meant by what he actually did say.

Can anyone parse this "NATURAL SELECTION the last said so SOPHISTICATE MISSILE in the hand of scientists launched against REALITY . " in a way that actually makes grammatical sense?

Since magnesium hydroxide is practically insoluble measuring the change in density would be quite difficult.

"I have been told that you can pump water over the surface of magnesium and create heavy water." You were misinformed.

T2 needs to be a load cell too. (or at least, that's a more conventional set up because it's a whole lot easier to work with.)

Coal and charcoal are complex mixtures which contain carbon as well as a whole lot of other compounds. (Incidentally, you missed out the nitrogen, sulphur and other things.) "Charcoal and coal are hydrocarbons (with much C and little H) which allows them to burn, as opposed to graphite." That's the sort of thinking that gave us this http://en.wikipedia.org/wiki/Windscale_fire Graphite burns well enough- it's just a bit hard to light. Also, if you roast coal you get coke which is much closer to pure carbon (almost all the O, N, H, and S are removed) but which is still used as fuel. "Coal is extracted in mines and normally pyrolysed before use" Not really, most of it is burned. Some is turned to coke, but since the other products i.e. the gas and tar are valuable this process is just as much "using" the coal as setting fire to it. "Carbon is the element and is also a synonym for graphite" and also for diamond and C60 The properties of high purity well ordered graphite are reasonably well known. The properties of mixtures like charcoal are, of course, different and more variable.

I prefer the old version. "A friend will help you move house. A real friend will help you move a body."

"Oh Flying Spaghetti Monster, I pray you'll help John Cuthber learn how to use quote tags someday." Quote tags are an invention of the Devil- so I only use them sometimes.

My best guess is that the coal rods are for fuel rather than anything else. Perhaps as a way of using coal dust which is otherwise a messy nuisance. According to this http://info.ngwa.org/gwol/pdf/722500216.PDF (P39) The resistivity of coal varies a lot.

"Should they seek psychiatrict help or go to a churh where they will hear words like "Love" "Truth" "Honesty." " I can hear the same words from politicians, but that doesn't mean I should believe them. "Solving the problem might take a LOT of prayer. " Indeed. It seems the prayers a good fraction of the population of Haiti http://en.wikipedia.org/wiki/Religion_in_Haiti couldn't steer a earthquake out of the way http://en.wikipedia.org/wiki/2010_Haiti_earthquake So the likelihood of all the prayers from this site achieving much is nearly nil. Feel free to prove me wrong by praying for me to win the lottery this week. This reminds me of the story told by Emo Philips. "when I was a Kid I used to pray that God would give me a bicycle. Then I realised He didn't work that way. So I stole bike and prayed for forgiveness."

Consider yourself duly censured for saying "but I simply will not tolerate any more mind numbing stupidity". Unless you actually plan to do something about it, you plan to tolerate it. Ignoring it may well be the best thing to do. Also, I personally feel that you are being unfair to kangaroo farts and disadvantaged armadillos.

That's still mainly word salad.

What is the science of improving the brain called? Education.

My best guess is that people who live in developing countries are more used to death and suffering so they are less troubled by sentencing people to it. Also, I'm fairly sure that London (for example) is more crowded now that it was 100 years ago when we still had the death penalty so I don't think overcrowding is a major factor.
