Landis Tests + for blood doping

[irishtrekker]

I haven't seen any stories that suggest it's him? They just say it's a cyclist and that they'll say who later, like they did for the others. He's MIA, but I'm willing to bet he's off getting that surgery he postponed for so long. I hope so, anyway. That would just crush me.

Its on 3 diff. news sites. His team confirmed its him. Maybe they news sites are all reporting something wrong but I doubt it. Dammit again.

AIGLE, Switzerland Jul 27, 2006 (AP)— While the cyclist who tested positive for doping at the Tour de France won't be identified until backup tests are complete, it does not appear to be any member of USA Cycling including champion Floyd Landis.
The International Cycling Union said Wednesday that an unidentified cyclist turned in a positive doping test during the Tour, widening the scandal that gripped this year's race before it began.

His name, team and nationality won't be released until the testing process is completed, including the analysis of a backup sample.

It doesn't appear to be this was 32 minutes ago

4th news agency...

CNN reports Floyd Landis has reported + for elevated levels of testosterone. His teammates confirm the report.

Now its testosterone. This is a bit more bizarre. One can have elevated testoterone levels at different levels naturally.

This Sport is for geeks.Doesn't surprise me that the resident Science teacher is interested.Tell me this,teacher,if the blasting power from many explosives comes from the massive amount of energy released from nitro-organic compounds(when Nitrogen gas is formed,)then why doesn't it also take a great deal of energy to form the nitro-organic compounds?(or does it indeed take a lot of energy to form them.)For instance,this compound:

How is this sport for geeks? I love cycling and am an aspiring amateur racer myself. I bike commuted every day of the work-week last year, through the rain and the dark, and it was the most addicting thing I've ever done! If nothing else, you get incredibly sexy calves and a seriously good cardio workout pumping up those hills...my partner's never looked hotter to me, and we both enjoy tearing across town together.

Just read the news about Landis. So bummed...although I do wonder about it, I mean, the guy has been a rather outspoken critic of dopers, and I'd imagine that he could have had some extra testosterone from those painkillers he has to inject for the hip. I guess either way, I still admire a guy who can ride the toughest race in the world on a dead joint. But man...I really hope it isn't true. Seems like the process of dope testing, as well as the how the results are interpreted, is extremely controversial. I wonder why?

When your foot slips,you guys must really get some pain in the loins.Not for me.

The conservation of energy is a powerful idea my good little dawg man. Here is the deal. Chemical bonds contain an enormous amount of energy. In fact the atom itself is held together by very powerful forces... thus breaking the atom, the atomic bomb, was quite a display. The bonding energy between the protons and neutrons of the atom is massive, getting it to come apart and to convert it into other forms of energy, heat, sound, and various forms of radiation, is a task we have sadly mastered. So quite simply, when the universe first cooled enough for atoms to actually be formed, that energy was trapped. We found a way to release it. The energy was already there when the universe first formec.
Now in explosives what you are basically doing is breaking chemical bonds that in most cases already exist. The energy is already there. All one is doing is taking chemical bond energy, and making it easier to turn into an enormous amount of heat energy very rapidly by tweaking a few bonds here and there and that does not require much energy. Kinda like pushing a big boulder on a frictionless surface 1 mm closer to the edge of a cliff. The heat energy released in the structure you found turns into gaseous products very rapidly which must expand. That my doggie lover, is an explosion. Wrap some tightly bound metal around this compound (that turns to gas very readily creating enormous pressures) any you got fragments of the metal shearing into millions of pieces and you tear a lot of people to shreds. Quite a horrible thing.

(CH2)6N4 + 4HNO3 → (CH2-N-NO2)3 + 3HCHO + NH4+ + NO3-

The reaction above taken from your site, is just the sythesis of said explosive. The first compound right after the--->

This reaction looks to me to be exergonic on its own. So you actually use no energy making the stuff, you give it off. So just making the stuff that is the explosive requires no energy at all, if fact it gives off energy. Thanks for the information.

One of my favorite teachers in the world taugh me physics for two years in high school. He was an amazing guy -- Vietnam vet, avid scuba diver, smart as hell but completely genuine and able to connect with all of the freaks and geeks like me...I still think about him and wonder if he's enjoying retirement. Sorry, totally OT, but just wanted to let you know that I think good science teachers are just fantastic people.

Yeah,you're getting a ton of energy released(when N2 GAS is formed.)To make these compounds that contain the Nitrogen,it doesn't seem like you are putting a lot of energy in(to make those,)but you sure get a ton of energy out of them.This is not supposed to be the way it works.Usually energy in,and energy out.What am I missing?
