  1. http://en.wikipedia.org/wiki/Tensor_tympani_muscle Voluntary control Contracting muscles produce vibration and sound[2]. Slow twitch fibers produce 10 to 30 contractions per second (equivalent to 10 to 30 Hz sound frequency). Fast twitch fibers produce 30 to 70 contractions per second (equivalent to 30 to 70 Hz sound frequency)[3]. The vibration can be witnessed and felt by highly tensing one's muscles, as when making a firm fist. The sound can be heard by pressing a highly tensed muscle against the ear, again a firm fist is a good example. The sound is usually described as a rumbling sound. Some individuals can voluntarily produce this rumbling sound by contracting the tensor tympani muscle of the middle ear. The rumbling sound can also be heard when the neck or jaw muscles are highly tensed.

  3. A picture of a Nuclear Power near me and the 50 mile evacuation radius if it were to effect the Salem plant. http://www.nzherald.co.nz/japan-tsunami/news/article.cfm?c_id=1503051&objectid=10712802 Heroes of Fukushima - 50 remain at Daiichi By Paul Harper 12:32 PM Wednesday Mar 16, 2011 Residents leaving Fukushima Prefecture in droves. Photo / AP Following yesterday's explosion at Fukushima Daiichi's unit 2 reactor, a decision was made by a manager on site to evacuate staff working in the area. But around 50 employees - dubbed the Fukushima 50 - have remained at the site working tirelessly around the clock to avoid possible meltdowns at three reactors at the quake-hit nuclear power plant. They are attempting to cool down fuel rods at three reactors by injecting seawater into them. Despite wearing protective clothing, experts say there will be negative effects to their health as a result of the radiation levels. David Richardson, a professor of epidemiology at the university of North Carolina who has studied the long-term health risks for nuclear plant workers, told the BBC those at Fukushima would receive in an hour the same amount of radiation a US nuclear worker is exposed over an entire career. "These workers in a few hours are getting fairly high doses I would say by contemporary standards for worker protection and that's likely to pose some risks down the line. "To my knowledge there's not a good way after exposure of trying to protect somebody from the risks of a subsequent later cancer." Lee Tin-lap, a toxicologist at a Hong Kong university, told Reuters the current radiation levels would not be immediately dangerous - but there could be long-term effects. "You are still breathing this into your lungs, and there is passive absorption in the skin, eyes and mouth and we really do not know what long-term impact that would have," he said. Following the fire at unit 4 yesterday, radiation levels peaked to levels dangerous for human health. At 10.22am (2.22pm NZT) a radioactivity monitoring post near the unit 3 reactor showed 400 millisieverts per hour, 400 times the amount an average person is exposed to in a year, the Japan Times reported. The radiation level was 100 millisieverts per hour near the unit 4 reactor and 30 millisieverts per hour between the unit 2 and 3 reactors. An official at the Institute of Applied Energy told the Japan Times radiation exposure of 7,000 to 10,000 millisieverts per hour is considered a lethal dose. "There is no doubt it is an amount that would have (a harmful) effect on the human body." Without protective gear, exposure to 100 millisieverts per hour can render a man infertile, one Japanese expert told NHK News. Chief Cabinet Secretary Yukio Edano said yesterday the levels would "no doubt" have a harmful effect on the human body. "But that is the amount right near the leak. The farther away, it drops." Radiation readings at the site have since fallen and stabilised, but are still above safe levels. The situation - which is currently rated a level 4 accident by Japanese officials (Chernobyl was a level 7) - has led to the evacuation of around 200,000 people from nine towns within 20km of the Fukushima Daiichi nuclear power plant and within 10km of the Fukushima Daini plant. Officials in Fukushima say around 190 people may have been exposed to radiation, and around 230,000 units of iodine have been distributed to evacuation centres in the area around Fukushima Daiichi and Fukushima Daini as a precautionary measure. The ingestion of stable iodine can help to prevent the accumulation of radioactive iodine in the thyroid. Residents outside of the evacuation areas have been advised by authorities to stay indoors.

  6. don't speak too soon. just saw this: LATEST UPDATE: Japan issues a state of emergency at a second nuclear power plant after its cooling system failed as thousands evacuate from the area near the Fukushima Daiichi nuclear power plant with radiation levels surging to 1,000 times their normal levels. There in lies the problem..... 1000 times their normal levels is still less than what you will get with a transcontinental flight. The limits imposed on nuclear facilities are less than many buildings. Grand Central Station in New York City would fail if they applied for a nuclear permit because the building emits too much radiation (Granite) How was I to know? Is there a higher power at work here? Haven’t they already gone though a enough! Isn’t anyone thinking this Nostradamus 2012 might just come true now? I surely hope not. I have no idea what else is in store maybe California would sink into the ocean after 10.0 on the Richter scale hits lasting 5mins? Get out of California now why you can save yourselves I have strong gut feeling the BIG ONE IS COMING! A Nuclear Engineer describes what is happening After scram (complete shutdown), about 5% is still there and that level reduces in half every 15 minutes. So for a 3000MW thermal reactor (like this one), 600MW is still there after immediate shutdown, 300MW 15 minutes later, 150MW 30 minutes later, and so forth. In a Boiling water reactor of that model, there are 3 cooling pumps in series (one for the cold feed and two after each hot feed loop). During a scram, those pumps must be shut off so that you don't get vibrational feedback (which could break a pipe). However, in the core is designed such that there are jet pumps (16 in parallel on the standard design) on the wet stream loop. This jet pump has no moving parts but can circulate the some water regardless of what the pumps are doing. Further, there is an single emergency main pump on the main loop that can push the full coolant load. This pump can be driven by any one of several diesel systems or a battery backup. If all of this fails, you then start to depend on the cold water back up re-condenser. In a BWR, underneath the first reactor containment, there is a large torus shaped area that is filled with a large amount of water. You can drop the steam from the reactor into this ring. The steam recondenses and reduces pressure. With the jet pumps, you can push the cold water into the reactor. This system can prevent first containment failure but doesn't prevent core damage. Then there is a second level containment. The design based accident for this reactor is assume a main coolant pipe dissappears (double guillotine break), all of the coolant flushes out and there is no way to cool down the reactor. In this case, 600MW post scram level will melt the reactor and possibly damage first containment, but second containment can hold the total heat produced post scram. You also have a coreium (term for molten core) catcher that catch the core, mix in a huge amount of radiation shield, and reduce the temperature. What is happening: Earthquake happens, core is scrammed because something might break. When the scram happens, main pumps turned off, emergency main pump turned on. However, the diesel generator doesn't work, maybe damage in earthquake, maybe something else. They turn on the battery system. It can last 4 hours, which is enough to reduce core power to 10kW. However, it is hot in there and 10kW is still enough to continue to make steam. So the water level (which tells you how much steam has been made) is dropping. They can go to the recondenser if they need to, but the recondenser doesn't rule out core damage (not melting, but material warping and oxidation) which would be expensive or impossible to repair. So for now, they are bringing in new coolant so they can prevent expensive core damage. They are NOWHERE close to the design based accident, and there is very little worry about containment failures. They are doing the evacuation because there isn't the safety factor they want, not because they are anywhere close to a radiation leak.

  10. I have not read this post but.... My state senator is beat watson [] http://www.nj.com/news/index.ssf/2011/03/rep_rush_holt_defeats_ibm_supe.html
  11. There was mention that the simpsons was wy nuclear was never accepted in America. Also yeah there is a funny situation in one of the nuclear plants around us. They do maintenance around now (february/march) every year and I believe the carp that thrive on the warm water die in mass. They are supposed to built a cooling tower for that sooner or later.
  12. I thought Jane Fonda was part of Nader's Raiders. If we had nuclear, there would be less of a energy problem we have now. I live in a state that has the highest percentage from nuclear power and we are fine.
  13. Why did God put our oil under their sand? We have plenty of oil in our unexplored wilderness but We want to be politically correct and leave that in a pristine state. That being said we do need to get our act together and further enhance our use of alternative power supplies. I am for nuclear power and as dangerous as it could be, for now we have to accept it. But if we are going to risk the potential disaster to the environment a nuclear power plant can bring, then we should also be willing to drill for oil anywhere where we can get it. Just my 2 cents. There is another option that I was going to post but it may cause to much of an uproar. Oh I hate Nader for this..... Nuclear is safer in nearly all respects comparatively to any form of energy. Coal kills more people per year in just mining the damn stuff than nuclear. Hydroelectric holds the record in killing people (a dam collapsed and wiped a town out) Europe has an anti movement to wind power due to the noise and ice throw (300 foot tall windturbines when subject to snow and ice and a burst of wind are known to throw sheets of ice 1/2 a mile or so that cut houses in half) This information came from my Croatian friend) Also if it were not for our government deciding to use uranium based power plants to keep a steady supply of nulcear weapons we most certainly would have gone to thorium based nuclear which is much safer and can be reprocessed and recycled over and over with very little nuclear waste.
  14. As with most other countries the price of gas is heavily taxed. We pay a little over 3 dollars now. I think from a german tourist I talked to on the train he said it was 2 euro a liter.
  15. You would have to hear it for yourself, there are many differences, it would be hard to really explain it and give you a clear picture. You may not like it ? I agree with dtel, every klipschorn I heard sounded a bit different to me (I heard now atleast 12) but I think it has to do with the room shape due to the horn. The Jubilee is more standard of a sound room to room. I think you should aim for the WMW ha!

  19. Although it may sound silly, if you can find a large cardboard box (good size 4X5 piece or larger) cut it out and place it on the wall or ceiling that you think the echo is coming from and then you can buy panels that suit the wall and look.
