    When will the IT Industry realise the content industry as the biggest threat to innovation of business models? Innovation is what creates wealth in business and any business that stifles innovation should be treated as a threat to all businesses.

    A list of some scientific studies on the effects of tritium with references in case there is any doubt regarding Triated water's effect on living beings.

    Tritium is biologically mutagenic *because* it's a low energy emitter. This characteristic makes readily absorbed by surrounding cells. The available evidence from studies conducted journal a list of effects. From those works;

    Tritium can be inhaled, ingested, or absorbed through skin. Eating food containing 3H can be even more damaging than drinking 3H bound in water. Consequently, an estimated radiation dose based only on ingestion of tritiated water may underestimate the health effects if the person has also consumed food contaminated with tritium. (Komatsu)

    Studies indicate that lower doses of tritium can cause more cell death (Dobson, 1976), mutations (Ito) and chromosome damage (Hori) per dose than higher tritium doses. Tritium can impart damage which is two or more times greater per dose than either x-rays or gamma rays.

    (Straume) (Dobson, 1976) There is no evidence of a threshold for damage from 3H exposure; even the smallest amount of tritium can have negative health impacts. (Dobson, 1974) Organically bound tritium (tritium bound in animal or plant tissue) can stay in the body for 10 years or more.

    It's often said "of all the elements in nuclear waste tritium is one of the more harmless ones" and while it's more benign than most other radioactive effluents it's toxicity should not be under-estimated.

    Tritium can cause mutations, tumors and cell death. (Rytomaa) Tritiated water is associated with significantly decreased weight of brain and genital tract organs in mice (Torok) and can cause irreversible loss of female germ cells in both mice and monkeys even at low concentrations. (Dobson, 1979) (Laskey) Tritium from tritiated water can become incorporated into DNA, the molecular basis of heredity for living organisms. DNA is especially sensitive to radiation. (Hori) A cell's exposure to tritium bound in DNA can be even more toxic than its exposure to tritium in water. (Straume)(Carr)

    First, as an isotope of hydrogen (the cell's most ubiquitous element), tritium can be incorporated into essentially all portions of the living machinery; and it is not innocuous -- deaths have occurred in industry from occupational overexposure. R. Lowry Dobson, MD, PhD. (1979)

    How many different types of intelligence are there? What is intelligence in the first place?

    I've pondered this very question. We are arrogant enough to presume that a new intelligence will be our creation by calling it 'Artificial'. Isn't it possible that a new intelligence could arise from the complexity of our systems, and as they grow in complexity 'evolve'.

    What if intelligence is a product of complexity and a conclusion of something arriving at a certain critical mass, we see the product of critical mass in nature all the time, maybe it's not unusual. Are we so different from animals or is it that we have more computing power at our disposal. Could it be possible that once the amount of nodes on the net reaches a certain point *something* happens.

    I know it's probably far fetched but is it possible our systems could reach a point of instinctual but not yet aware, and if it reaches that point of awareness will we even recognise 'it' as intelligence. Could it happen and we don't notice it?

    On a more radical note, I propose that there already is a form of instinctual intelligence called 'Human Society'. It's laws and constructs define it's behavior and the governments, corporations and other things that make up it's vital organs make it largely hostile to human life. Consider for a moment bee and ant colonies, they act differently as a whole surely it's the same with humanity. Is it possible that we have already created a form of Artifical Intelligence, our civilisation, defined it's behavior through law and we are not even aware of it's instinctual existance. What if that forms the body and our super complex Internetwork forms the brain?

    What then can we say about it's mind?

  16. At what level should the NRC shut down the plant? on Tritium Leak At Vermont Nuclear Plant Grows · · Score: 1

    From my understanding the criteria for shutting down a Nuclear Power plant is assessed on mainly two parameters.

    A "Licencee Event Report" (LER) is submitted for issues above a safety significance threshold. For example at Davis-Besse, the frequency of the replacement water filters was out of spec. It should have signaled that something is going wrong in the reactor. This is the type of event that should be signaled as a LER even if it seems insignificant.

    The second stage is an "Accident Sequence Precursor" (ASP) which defines events that characterise the lead up to an accident at a Nuclear Plant. Sticking with the Davis Besse example which (from memory) was caused by a fine jet of borated water spraying onto the the *inside* of the reactor head. Water rusts steel, reactor head is steel, rust goes in water, water goes through filter, filter catches rust, management says it's ok, reactor head gets hole [if allowed to continue - reactor core breach and potential for explosion] - 'Accident Sequence Precursor'.

    By examining the trends for LER's and ASP statistically for all nuclear plants the NRC can get an overview of the operational state of all the plants *if* the operators of the plant co-operate and share their operational data (which I also believe to be a legal obligation of the Licensee) with the NRC. At issue is the characterisation of what sort of events should lead to a LER.

    At the Davis Besse plant I believe that it led to criminal charges as management allowed the plant to operate outside of it's "Basis Design" which is a known operational characteristic of the plant. Filter replacement intervals had been defined and were known about and thus should have characterised the plant as "not operating safely". I'm not sure if the criminal charges were placed because management should have reported several LERs instead of inspectors finding a hole in the reactor head when it was shutdown.

    "Basis Design Issues" (BDI) are also revealed whilst the reactors are operating - they are not all known when the reactor becomes operational due to the complexity of the machine. Industry wide knowledge of LERs contribute to knowing what BDIs lead to ASPs (and a sentence full of acronyms). Further information can be found in the NRC document NUREG 1275 - Volume 14 "Causes and Significance of Design Basis Issues at U.S Nuclear Power Plants"

    As often observed in plane crashes it's a combination of insignificant issues that lead to a problem. The question at hand is whether the leak is indicative of a larger problem for example; lets say our leak has led to filling a concrete void under the reactor core with water. Together the two events are insignificant, however when combined with a third event like a SCRAM of the reactor that suddenly heats that water in the concrete void you have the potential for a serious explosion.

    I'm not saying thats whats happening, just that the water leak my be an indicator (a LER) of a larger issue which is used as part of the determination if the plant should be shut down. A leak of triated water into the environment is a serious concern. What is yet to be revealed is if the leak reveals a Basis Design Issue that is serious enough to be a part of an Accident Sequence Precursor.

    No matter what the outcome the continued operation of the reactor will probably be determined on *if* they can find the leak. Anything that affects the cooling capacity of a Nuclear Reactor is not a situation that can be allowed to persist.

    Yup. Personal experience, too. I happen to have been a non typical-geek :

    I think I may fall in this category as well. I still had trouble with bullies but on reflection it may have been because I was self-centered. With plenty of friends outside of school - which was the early 80's - it wasn't really a priority for me to be interested in the kids at my school. Computers and electronics occupied my spare time but I also played a lot of hockey and cycling.

    I didn't share the things I played with because - frankly - most other kids didn't understand what to do with an electronics lab kit. One kid decided to trick me by acting all curious about what a 'floppy disk' was and when I showed him one (that contained the code I was writing at the time) he decided it would be a good idea to scrape his finger along the media. As I watched in horror he said 'you aren't supposed to do that are you?'.

    As soon as the kids found out I was a computer 'geek' or 'nerd' the bullying started. I would try to hide and avoid a confrontation until I was cornered. Problem for them was I had a foul temper and didn't they get a nasty surprise. I think they thought because I was trying to avoid them and just play with my computers and electronics I was somehow afraid, which I was, but of them and my temper in equal measure. I hated being bullied and every time it happened the fear, frustration and anger would build until confrontation was unavoidable. I never instigated it but I finished it. Once every 6 months one of these losers would come along to make life a misery.

    Towards the end of school everyone was asked what they were going to do when they left school. While everyone else was saying 'mechanic' or 'hairdresser' I outlined my 5 year plan to get into the IT industry. Most of the kids looked at me like I was some kind of loser but as I had already been paid for my code and magazine contributions I was confident that I wasn't. 20 years of IT work later it's a genuine pleasure to be talking to like minded people here. I still feel the joy of working with code that I did as a boy and no bully could ever take that away from me.

    They are completely put off by target who just ignore them.

    And they are even more astonished if their potential victim laughs their attempts off.

    I wish I had this kind of advice when I was a kid so I could have controlled the situation a little better only because I feel I could have done better at school. Even so I feel that there it's a valuable life skill to have learned how to confront bullies. It's satisfying to look at them while they apologise with a black eye and a busted nose. Now I don't get intimidated easily and this has translated to the ability to deal with drunken assholes as well as confidence in business negotiations.
