  1. Re:Sorry, let me clarify on Worldwide Shortage of Barium · · Score: 1

    Medical-purity BaSO4 is likely to be a further cut above the lab-grade stuff you can buy from any number of common chemical suppliers - purifying it is trivial - they do it all the time to make the stuff in the first place.

    Purifying it of hepatitis virus is NOT trivial (and I won't even go into what's necessary to denature prions).

    Once it's been through the intestinal tract of one patient, making it pure enough to be inserted to another's is likely to be far more expensive than purifying something that came out of a mine.

  2. Iodine is now restricted by federal law. on Worldwide Shortage of Barium · · Score: 2

    Iodine is used in the illegal manufacture of Methamphetamine. As a resule, Iodine has recently been reclassified as a List I chemical under federal law. Those handling or selling iodine and its compounds must now go through a bunch of bureaucratic red tape with the DEA.

    I found this out right after the Fukushima disaster (when I tried to find some potassium iodide supplement {or other potable iodine compound, such as water purification tablets or tincture of iodine} to take to bump my iodine level before the fallout arrived). Guess what: None to be found. Not just because it had been sold out by those who responded faster. But because most retailers (including large drug store chains and sporting goods stores) had stopped carrying it, rather than deal with the drug warriors.

    I suspect that, even if some iodine compound is suitable for a gastrointestinal contrast medium, the drug industry has not been interested in developing it and seeking approval, at least until now. While barium was in cheap supply why should they spend money developing a replacement whose distribution would involve expensive federal red tape?

    Not owning a gun makes you safer .

    Ah, the Lippmann study rears it's head.

    Hint: There is one time that people in the gun culture believe it is not merely moral, but sometimes morally required, to lie. That is when someone asks you about whether you have/what guns you have, in an inappropriate context and/or when they're not entitled to the information. An example of such a context is when you're in a doctor's office or emergency room being treated for something NOT related to an injury resulting from your own firearm.

    The right answer to such questions is "no", unless it's obvious (like from an accidental self-inflicted wound) the answer must be "yes" - but with details withheld.

    Such reporting bias invalidates studies dependent on questioning the subjects. (And how else can you obtain the information?) Authors of similar studies in the past (notably Kellerman, author of the debunked study behind the "43 times more likely" meme) have actually repudiated and withdrawn their own work once things like this were pointed out.

    If they were talking IPv6, UDP packet overhead is 48 bytes, leaving only 22 for keeping the CODECs synchronized and specifying how much silence is being encoded.

    While I don't know whether, or how, skype does this, it would be reasonable to either actually send the connection's real background noise at a reduced bit rate, or send some small amount of information to the receiving end in a mechanism for avoiding artifacts (like those I've heard on AT&T cell service) which make it obvious that a noise generator is being switched on and off, or repeating waveforms that sound like a "Max Headroom" style failing connection.

  7. Re:Perpetual war on Senate Renews Warrantless Eavesdropping Act · · Score: 1

    We have been cutting taxes for the past ten years. It has not worked.

    First: The key is cutting SPENDING. As long as the government spends enormous amounts of money the value behind that money is sucked out of the public sector economy, depressing it, regardless of whether this is done by taxes, inflation, or borrowing. Spending has EXPLODED over the past ten years - especially with the "bailouts".

    The different modes of ripping off the people hurt the economy in somewhat different ways, and some have greater "hurt multipliers" than others. But the value bled out of the economy to be squandered on non-producing (or under-producing) government projects sets a minimum level of damage.

    Second: Most of the so-called "tax cuts" weren't. They were typically government giveaways administered through the IRS. To be a "tax cut" of the form that stimulates productivity it must be a cut in the RATE of tax on a FUTURE activity, and must be passed into law or regulation in time to influence the taxpayer to make a decision to perform the action that is now taxed less. Things like a lump sum given to each tax filer and passed into law after the taxpayer has already made all his economic decisions and done all his actions fails on both tests, no matter how many politicians call it a "tax cut".

  8. Sometimes old ideas suddenly become practical. on Mini-Tornadoes For Generating Electricity · · Score: 1

    an old idea from decades ago when all manner of weird and quirky ideas was bandied about from solar panels in orbit many miles square beaming microwave energy back to a receiver on earth (except any living thing in its path would be fried!),

    Except that:
      - Things wouldn't be fried, microwave-oven style, because microwave oven makers picked a frequency that is strongly absorbed by water (to heat food) while space-solar people picked on that passes through water very well (to not waste power heating clouds, birds, cows, ...). Intensity of the microwave heating would be about a tenth solar input - and birds in outdoor tests of such systems at realistic power levels mostly ignored them (except on cold nights when they huddled near the transmitting antennas)
      - This might have been practical even back in the '70s when it was first proposed - except NASA shot it down with high priced lift-to-orbit systems and an analysis with a fundamental error (turbine size) that made a specialized lift system look far too expensive.
      - Recent developments (privatization of space launches, improvements in the technology of photovoltaic collectors,power radio, and high-efficiency lasers for ground-based lift systems) have made the cost and price/performance equations better - by orders of magnitude. (See Keith Henson's recent papers on this.)

    Saw a makerbot being demonstrated with black ABS plastic at a conference last month. The parts made with it were STRONG. (Replacement components of the print head had been manufactured this way.) Also a sample was being made with internal, hollow, completely enclosed and sealed, honeycomb cells, which made it very light without substantially reducing its strength or dimensional tolerances. Should be ideal for things you need to float. (Try building THAT without a 3-D printer: You'd need to bond two or more pieces together.)

    I understand one of the problems with the makerbot that metal-frame follow-ons like this are trying to address is that the wooden frame flexes and changes size with relative humidity, making tolerances lower than they could be with a metal frame.

      - Reducing the guns "in circulation" will reduce violence.

    Last I heard of the plan the next step after WB-8 (and maybe another small model with a different symmetry), if the scaling rules worked out in practice, was to be a beyond-breakeven proof-of-concept machine with 100 MW output, for about $200M - which, if it could run continuously for little ongoing cost, would be cheaper than a solar panel farm (which only gets about 5 hour-equivalents of the panel rating per day). I was hoping that the end-of-2012 news would be that WB-8 had worked as expected and they were going ahead with the real thing. So I was both elated and disappointed at the news that things seemed to be working as expected but that they were going to spend a couple more years doing engineering and science with WB-8.

    I'm NO friend of Mitt Romney - to put it mildly. But let's not blame him for something that's not his doing.

    1) Because Romney was running for president, US law REQUIRES he put his money in a blind trust.

    2) Also under US law the trustee has a "fiduciary duty" to do his reasonable best to protect and grow Romney's money for him. That includes seeing to it that is not taxed substantially more than the law requires.

    TFA notes the language "Assembled in the USA" so that's pretty clear.

"Made in Japan" was synonymous with cheap and shoddy.

    "Assembled in" doesn't say squat about the components in the assembly. But at least it does tell you where the final assembly process is employing workers.
