  1. When I was a doctor... on Japan Imposes "Fine On Fat" · · Score: 3, Informative

    When I was working on the vascular surgery ward, the beds were crammed with two kinds of people ; smokers, and type-2 diabetics. Many of them were both kinds. Most type-2 diabetes is self-inflicted and can be avoided through managing your weight and diet properly. Combining smoking with type-2 diabetes is basically asking to have your legs amputated.

    When I was working on the pulmonary ward, the beds were crammed with 2 kinds of people - smokers, and asthmatics.

    When I was working the infectious diseases ward, the patients were predominately junkies, with conditions brought on as a result of their habit.

    When I was on ENT, the patients were of three types ; young children needing routine surgery like tonsillectomies and ear grommets, persistent nosebleeds, and really nasty mouth and throat cancers. The cancer patients were, you guessed it, all smokers.

    So the vast majority of patients with chronic, manageable, expensive conditions, some requiring multiple surgeries just to get back a fraction of the function they should have had, were smokers, and fatties, and the worst of them were fat smokers.

    Smoking and obesity cost the health service huge sweaty wads of money and I find your assertion to the contrary to be baseless.

    This guy (who isn't even a programmer by trade - he's a radiologist) wrote a USB webcam driver because he bought his daughters a pair of webcams that didn't work in Linux. From there, he realized that much of the code in webcam drivers is applicable to all webcams.. the end result is that his drivers now support a large number of cameras with various chipsets, and that any improvements to the driver code improve the drivers for ALL those cameras and not just the ones from a single vendor.

    That's a statistic ; not a fact.

    Statistically speaking, yes, women are not as strong as men ; but this is more to do with male and female culture differences than actual physical makeup.

    On the tissue level, both sexes are built of the same bone and muscle materials. Even if you take into account the effects of higher androgen levels in men, there is no reason that a woman cannot achieve musculature equal to a man of similar height.

    Women DO tend to be shorter than men, because their skeletal structure matures earlier, so statistically speaking, their mass will be less than a man. Again, this does not account for any particular individual.

    As for your assertion that an athletic woman would be beaten by a "normal, decently in shape man", statistics state that "normal" does NOT mean "decently in shape" in most western nations.

    I dated a Phys. Ed. teacher once ; she was an ex-member of a national swimming squad. While I was in my school rowing team and worked out regularly, she could probably have kicked my ass. Her upper body was most definitely not weak.

    Strength is a minor part of combat ability anyway. As Firefly fans will know, it takes less than a pound of force with a sword to break skin. It's far more important that you choose a weapon appropriate to your build, and learn to wield it properly.

    And most people will get badly hurt in one-on-one fighting, especially if their ability is reasonably matched to their opponent... on BOTH sides of the fight. It's only highly imbalanced fights where the "hero" has a level of ability far higher than the "henchmen" that the hero gets off scot-free while the henchmen eat dirt.

    "electrons are injected directly into the powergrid" That's a piece of whimsy on the part of the submitter, but it's not entirely inaccurate. The reactor is designed to collect power in two ways ; primarily from the energy of the emitted alpha particles, secondarily from an x-ray photon converter (would be a "solar panel" if it was solar rays, I suppose). Neither method involves the usual intervening step of using the heat of reaction products to boil water to run through a turbine, and both could be called a direct injection of electrons.

    This has all the hallmarks of a bogus project that has succceeded in milking some funding out of some gullible soul You could say the same of ITER and other tokamak fusion projects ...

      * No viable product
      * No discernible progress

    Oh wait, you can't say any of those things about the dense plasma focus. Nowhere close to the billions that have been poured into tokamaks, it's a viable product on it's own (as a portable bright X-Ray source), and despite the apparent handicaps of a slightly kooky project leader and miniscule funding, their numbers look just as good, if not better, than ITER.

    we are not even talking about pure deuterium You are quite correct. We are not talking about ANY deuterium ; this is a proton-boron fusion process.

    At that temperature the atoms will move about a bit, to say the least .. there will be highly energetic collisions all over the place Watch the google video ; the reaction is confined to a tiny plasma toroid, which is how it achieves such a high temperature. The p-B reaction itself just emits alpha particles (otherwise known as helium ions), and plenty of X-rays, which do not persist and are intended to be captured to generate part of the power output.

    Ionization energy of atomic hydrogen

    Proton-boron fusion

    1 x p + 1 11B => 3 x 4He + 8.7 MeV

    So you're only off by around 5 orders of magnitude.

    The electrolysis is by far the lowest-energy part of the process. The bulk of the energy in fusion research is spent energizing and containing the plasma, and the difficulty of collecting that much energy from your reaction products is the reason that no fusion project so far breaks even.
