はてなキーワード: speedとは
2012年ぐらいのOSXは画像フィードをスクリーンセーバに入力するという方法で自分のtumblrをスクリーンセーバ化するというのが出来たけど(たぶん)Mavericks以降は,それが無くなってしまったので代替方法について書きたいと思う。
まず tumblub を開き「staff」に自分のtumblr IDを入れる。「Random」のチェックボックスをチェックし「Photo size」を500, 「Animation speed:」をslowとチェックしshowボタンを押す。以下はサンプルとして作成したotsune氏のtumblr IDを入力したスクリーンセーバの入力データだ。女性の尻がいっぱい出てくるので職場のMacのスクリーンセーバにすると軽くアナーキー感が出て良いと思う。
speedは好みで変えて良い。ぼくは14400くらいが良いと思っているのでクエリストリングのところをそんぐらいに手で変更して使っている。
Screensaver Ninja - Never miss important information again という任意のwebページをスクリーンセーバとして表示できるツールがある。1200円。本来はなんらかのビジネスのダッシュボードなどを表示する用っぽい。
購入しアクティベーションしてScreensaver Ninjaを起動し「Add new site」する。先ほどのURLを追加する。
「システム環境設定」から「デスクトップとスクリーンセーバ」を選び「Ninja」を選ぶ。これで女性の尻がどんどん流れてくるスクリーンセーバの完成である。
もちろん自分のtumblrをスクリーンセーバにする事も可能だ。
普段肌色をreblogするのにも緊張感が走るし,肌色が離席中の職場Macに出てきてしまったらしまったで同僚の人とかと会話も弾んで良いと思うのでみなさん,どんどんスクリーンセーバを設定すれば良いと思う。
トラックバックしてくれた人に教えてもらったがbrockgr/websaveというScreensaver Ninjaと同等のことができる無料ツールがあるのでそれを使おう。

Ottavio Cinquanta
From Wikipedia, the free encyclopedia
2011 Rostelecom Cup - Ottavio Cinquanta.jpg
Ottavio Cinquanta (born 15 August 1938, in Rome), is President of the International Skating Union and a member of the International Olympic Committee.
He has held the ISU position since 1994 and the IOC position since 1996.
In 2000 he was elected member of the IOC Executive Committee, position that he has held until 2008.
Prior to becoming ISU President he was ISU Vice President and before the Chair of its Technical Committee for Short Track Speed Skating.
Cinquanta grew up in Milan, Italy, where he practiced as an ice hockey player, in athletics and as an ice speed skater. Cinquanta attended university and he was mainly active in business administration. At the time of his election to the ISU Presidency, at the age of 56, he retired from his position as a manager of an international chemical company.
When Cinquanta was first elected to the ISU Presidency, he was initially regarded as a progressive who introduced prize money at ISU Events after negotiating several commercial contracts, including an important television contract with ABC Sports. This allowed the ISU to retain athletes who might have otherwise left Olympic-eligible skating to participate in unsanctioned made-for-television professional skating competitions, which were then offering large appearance fees to top skaters. The television money also allowed the ISU to sustain a variety of development programs in both Figure Skating and Speed Skating branches, including, for example, the ISU Grand Prix of Figure Skating.
However, because of his speed skating background, Cinquanta has been the subject of a considerable amount of criticism from the figure skating community, particularly in Canada and the United States. During the 2002 Olympic Winter Games figure skating scandal, he was criticized for his evasiveness and his admission that he didn't "know figure skating so well".[1] In spite of his professed lack of knowledge about the sport, he proposed a new scoring system for figure skating[2] whose major feature is secrecy which would prevent anyone from ever knowing how an individual judge had marked the competition. The implementation of secret judging at the 2003 World Figure Skating Championships in Washington, D.C., was controversial enough to result in a fan protest at that event,[3] with Cinquanta personally being jeered by the audience whenever he was introduced.[4][5]
Cinquanta had previously been loudly booed by fans at the 1996 World Figure Skating Championships in Edmonton, Alberta, after he invoked a technicality to prevent local skating favorite Kurt Browning from skating in the opening ceremony of that event[6][7] and again at the 1998 Championships in Minneapolis, Minnesota.[8]
Cinquanta has been consecutively reelected to the ISU Presidency at all the ISU elective Congresses and it is estimated[by whom?] that since his first election in 1994, approximately thirty innovations have been introduced in the International Skating Union regarding the two branches administered of Figure Skating and Speed Skating.

ニューヨーク証券取引所のとある一企業の株式売買の様子を0.5秒だけ映像化した動画を見た人の感想です。
https://news.ycombinator.com/item?id=5678116
いつだったか、ソースコードを全部印刷したことがあるよ。その時のソースコードはASP、HTML、CSS、Javascriptで、僕の雇い主の最も重要なWebサイトのホームページを1ページ読み込んで出力したんだ。僕は紙を一枚一枚テープで繋いで壁に吊り下げた。
同僚と貴重な意見を交わすことができたね。技術に明るくなかったみんなは（大半はそうだったけど）凄く驚いてたよ。彼らが毎回ホームページをロードするごとに（1秒以内の短い時間で）こんなにも多くのテキストが読み込まれ、実行されることにね。
そんなことをしてどんな意味があったって？プリントアウトしたことが僕たちの会話に一定した感情的な緊張をもたらすのに役立ったんだ。1ページを読む裏で行われてる複雑なことに直に対面したことで"今すぐにやって、簡単でしょう"とプロジェクトに要求することが困難だってわかったんだよ。
同様に、高頻度で取引を行う果てしないスピードと複雑さに焦点をあてたこの話(注: HNのトピックです)も、疎外感や恐怖といった感情的な緊張をもたらすのを助けてるね。"誰もコントロールできない技術の暴力を解き放ったかもしれない"と、反射的にフランケンシュタインやターミネーターと争ったのと同様の契機になるかもしれない。
でも、テクノロジーに対して思慮と公正さをもって対峙すれば、もちろん、そんな気持ちは起きないのだけど。僕らのくだんないパンフレットのようなウェブサイトが行き着く先はそんなに複雑じゃないと思ったよ。
One time I printed out all the code--at that time ASP, HTML, CSS, and Javascript--that got executed for one page load of the homepage of my employer's primary website. I taped the pieces of paper end-to-end and hung them on my wall.
It made a great conversation piece with my coworkers. Non-technical folks (most of them) were astounded that so much text was being interpretted and executed every single time they loaded the homepage (in less than a second).
What was the point? It helped set a certain emotional tone to our conversations. Folks found it a lot harder to demand their project be done "right now, it's easy" when directly confronted with the complexity behind a single page load.
Likewise, stories that highlight the immense speed and complexity of high frequency trading help set an emotional tone of alienation and fear. It helps trigger the same reflex Frankenstein and The Terminator played off of: "maybe we're unleashing technological forces that no one can control."
But of course if you are well and truly versed in a technology, that feeling goes away. I knew that our crappy brochure website was not very complicated as websites go.

インフォグラフィックス、なんて言葉ができて久しいけど(今じゃこんなサイトまであるんだね)、
僕が初めてこの言葉を知ったのはウェブではなく、生物学だった。
バイオインフォマティクスについて、東大のサイエンスカフェに聞きに行った時、
この学問は「生物」と「情報」が融合した学問だけど、さらに美術と融合させるような試みも
欧米ではあるんですよ、みたいな話を聞いて、美しく染め上げられた生体写真や幾何学的な何かのノードの写真に
研究成果をこうやって示す方法があるのだと衝撃をうけたのをよく覚えている(...内容は忘れました、すみません)。
そんなインフォグラフィックスは、美術的なセンスと才能と技量が要求されるけど、
ただ単にプリントアウトして見せるだけでも、クライアントを説得するには十分だと
このコメントを読んで、その素朴さにはっとなった。
試しにTwitterのホーム画面でソースコードを見たら、2200行あった。
これにロードされるjavascriptのライブラリやCSSを加えたらどうなってしまうんだろう。
僕は今、テクノロジーの詳細がわけ分からないという普通の人の感覚を抱きながら一方で、
ティム・バーナーズ＝リーがWWWを考案してから積み上げられてきた技術的資産を前に途方に暮れている。
おそらく技術屋として中途半端だから、こんなないまぜな気持ちなのだけど、

http://www.dailytitan.com/2011/04/the-inevitable-decline-of-cds/より転載：
Almost 11 years ago, stores like Tower Records and Wherehouse Music were mobbed with over 2.4 million people waiting to purchase N'Sync's No Strings Attached album.
Today, music stores like those are almost non-existent, and those that are still in business do not receive much foot traffic in the CD aisles.
The sales of compact disc albums have seen a significant decline since that record week in 2000. Nielsen Sound Scan reported that over 730 million units sold in 2000. In 2010, album sales hit an all-time low of 326 million units sold, including digitally downloaded albums.
"Nobody wants to go through the trouble of going to a music store, finding and buying a CD, opening the package, etc. Now we just click a button on the Internet and instantly have music," said Keegan Gogerty, 22, a singer/songwriter and radio-TV-film student.
Digitally downloading music has played a major role in the decline of CD sales, but the biggest factor is the illegal digital downloading of music.
Pirating music has been on the rise since Napster launched its peer-to-peer file-sharing software in 1999. Napster was known for allowing users to share and trade their MP3 files with one another over the Internet for free.
Napster was later shut down after multiple lawsuits, but more peer-to-peer outlets surfaced, such as Kazaa, Morpheus and LimeWire.
Peer-to-peer sharing has grown from MP3 sharing to multiple-file sharing and torrent sharing.
"I don't blame people for not wanting to purchase music. If I want to support a band, I will attend their concerts or buy a T-shirt. That is where they receive the most royalties anyway," said Charlie Hatano, an advertising graduate student.
"We live in a generation of simple living, the digital age," Gogerty said.
Online music stores such as iTunes and Napster give consumers the option to purchase music at the click of a button.
However, Ashley Sutton, 24, a psychology major, still buys compact discs.
"Nothing beats getting a new CD, reading the booklet and reading the lyrics," said Sutton. "I agree Internet downloading is more convenient, but I find owning a physical CD collection rewarding, rather than clogging up my computer with music I download."
The music industry has tried to crack down on the peer-to-peer file-sharing software programs, but people are still using different forms of illegally downloading or sharing music.
"I'll admit that I have had friends burn an album for me or copy them into my computer for my iPod," Sutton said. Making copies of CDs, illegally downloading the album and sharing, it is all the same.
In an interview with USAToday.com, the Recording Industry Association of America's (RIAA) CEO said illegal music sharing has been "contained."
"I remember people downloading one song at a time with Napster. More recently I have seen people download 10 albums at the same speed they could download one song in 1999," Hatano said.

The green environmental protection battery is to point to in recent years has been put into use or are development, the development of kind of high performance, no pollution batteries. At present already use large nickel metal hydride battery, the lithium ion battery and is expanded use of mercury free alkaline battery manganese zinc and rechargeable batteries and is research and development of lithium or lithium ion plastic pack and fuel cells belong to this category. In addition, it is widely used and use of solar energy for photoelectric convert solar cell (also called photovoltaic power generation), can also be included in this category.
Nickel metal hydride battery (Ni-MH) and nickel cadmium battery (Ni-Cd) have the same working voltage (1.2 V), due to the adoption of rare earth alloy or TiNi alloy anode materials for the activity of hydrogen storage material, replacing the carcinogen cadmium, which not only makes this battery became a kind of green environmental protection battery, and make a battery of energy than increased nearly 40%, to 80-60 Wh/kg and 210-240 Wh/L. The battery is 90 s gradually realize industrialization PANASONIC VW-VBK360 Battery , and the first to use in the cell phone battery. At present although it on their dominance of the gradually be lithium ion battery replaced, but mobile phone applications in Europe and America, and its market share is still at about 50%.
The lithium ion battery (Li-ion) is by can make the lithium ion embedding and take off the carbon embedded as negative, reversible intercalated-li metal oxide as the positive (LiCoO2, LiNiO2 or LiMn2O4) and organic electrolyte constitute, the working voltage of 3.6 V, so a lithium-ion battery is equivalent to three cadmium nickel metal hydride battery or nickel. Thus the batteries than energy is the over 100 Wh/kg and 280 Wh/L, and considerably more than the nickel metal hydride battery than energy. In view of the above advantages, since the 1993-2000 in just a few years, its production and usage with extremely high speed growth.
Alkaline manganese zinc dry (alkaline) compared with ordinary dry cell size has higher capacity PANASONIC CGA-S005E Battery, and have high discharge current ability. In recent years has been used on mercury zinc powder, therefore make the battery become a green battery, and become the mainstream battery products, at present the alkaline xinmeng dry cell is still BP machine use most power supply. At the same time, the world is the battery charged on the sex, an American company has launched a charged battery alkali manganese, product and application of slow growth. Such batteries keep the battery discharge characteristics, but also can be recharged using a dozen times to hundreds of times (deep recharge cycles life of about 25 times).
Lithium plastic battery (LIP) is for lithium metal anode, conductive polymers of electrolyte for new battery, the energy than has reached 170 Wh/kg and 350 Wh/L. The lithium ion battery is will present plastic of organic lithium ion battery electrolyte stored in a polymer membrane, or use conductive polymer as electrolyte, make a battery in no free the electrolyte. Such batteries can use aluminum plastic composite membrane realize hot pressing encapsulation, with light weight, shape can be arbitrary change, safety better characteristics.
Fuel cells (FC) is a kind of use of fuel (such as hydrogen or contain fuel) and antioxidant (such as pure oxygen or the oxygen in air) for power generation device directly, because avoided the carnot cycle limit, this power unit is not only high efficiency (electrochemical reactions conversion efficiency can be as high as 40% or more), and no pollution discharge gas, so is the future of efficient and clean power generation method. Many companies at home and abroad are engaged in development for mobile phones, notebook computers, the PEM fuel cell, once put into application, and its economy benefit greatly.
Seal lead-acid battery is a kind of lead-acid batteries.
The following new green battery technology and related industry development is rapid.
1. Hydrogen storage material and nickel metal hydride Battery-the nimh batteries (PANASONIC CGA-S101E/1B Battery)
2. Lithium ion embedded material and liquid electrolyte of lithium ion battery
3. Polymer electrolyte of lithium battery or lithium ion battery
4. Zinc air battery and PEM fuel cell
In addition to the above, in view of the communication industry growth, China's battery industry is with extremely high speed to promote environmental protection mercury-free alkali manganese zinc original pool and rechargeable batteries and seal lead-acid battery technology development and application expansion market.

If you have had for no reason undoubtedly,Panasonic HDC-TM900 Charge do not forget to evaluate any hands-on plus try out to achieve the just about all working experience you could as a result. A good number of manuals can verify all to consider about precisely how towards employ that video camera. Keep in mind, it should receive baffling you will be know simple digital camera words.
The most crucial several stipulations to consider together with taking photographs might be:
1. Shutter Full speed
step 2. Aperture

February With the world going mobile and billions of new devices requiring electrical storage, battery technology is almost certainly due for a renaissance in the near future and recent developments suggest MIT will play a role in the next significant battery technology. Less than a week ago, we reported on work being done by MIT's Laboratory for Electromagnetic and Electronic Systems (LEES) that could become the first technologically significant and economically viable alternative to conventional batteries in 200 years. Now a second new and highly promising battery technology is emerging from MIT - a new type of lithium battery that could become a cheaper alternative to the batteries that now power hybrid electric cars.
Until now, lithium batteries have not had the rapid charging capability or safety level needed for use in cars. Hybrid cars now run on nickel metal hydride batteries, which power an electric motor and can rapidly recharge while the car is decelerating or standing still.
But lithium nickel manganese oxide, described in a paper to be published in Science on Feb. 17, could revolutionize the hybrid car industry -- a sector that has "enormous growth potential," says Gerbrand Ceder, MIT professor of materials science and engineering, who led the project.
"The writing is on the wall. It's clearly happening," said Ceder, who said that a couple of companies are already interested in licensing the new lithium battery technology.
The new material is more stable (and thus safer) than lithium cobalt oxide batteries, which are used to power small electronic devices like cell phones, laptop computers, rechargeable personal digital assistants (PDAs) and such medical devices as pacemakers.
The small safety risk posed by lithium cobalt oxide is manageable in small devices but makes the material not viable for the larger batteries needed to run hybrid cars, Ceder said. Cobalt is also fairly expensive, he said.
The MIT team's new lithium battery contains manganese and nickel, which are cheaper than cobalt.
Scientists already knew that lithium nickel manganese oxide could store a lot of energy, but the material took too long to charge to be commercially useful. The MIT researchers set out to modify the material's structure to make it capable of charging and discharging more quickly.
Lithium nickel manganese oxide consists of layers of metal (nickel and manganese) separated from lithium layers by oxygen. The major problem with the compound was that the crystalline structure was too "disordered," meaning that the nickel and lithium were drawn to each other, interfering with the flow of lithium ions and slowing down the charging rate.
Lithium ions carry the battery's charge, so to maximize the speed at which the battery can charge and discharge, the researchers designed and synthesized a material with a very ordered crystalline structure, allowing lithium ions to freely flow between the metal layers.
A battery made from the new material can charge or discharge in about 10 minutes -- about 10 times faster than the unmodified lithium nickel manganese oxide. That brings it much closer to the timeframe needed for hybrid car batteries, Ceder said.
Before the material can be used commercially, the manufacturing process needs to be made less expensive, and a few other modifications will likely be necessary, Ceder said.
Other potential applications for the new lithium battery include power tools, electric bikes, and power backup for renewable energy sources.
The lead author on the research paper is Kisuk Kang, a graduate student in Ceder's lab. Ying Shirley Meng, a postdoctoral associate in materials science and engineering at MIT, and Julien Breger and Clare P. Grey of the State University of New York at Stony Brook are also authors on the paper.
The research was funded by the National Science Foundation and the U.S. Department of Energy.

Due to the nature of a digital camera, they need a lot of voltage and also need to keep good battery long periods of inactivity digital camera rechargeable batteries to a big hit, many current digital camera has a flash, may also make a short film, the two characteristics is very good, but can drain battery two times normal speed, photo shooting.
Most people are familiar with basic rechargeable battery, but the key to finding a good a doctor to give your digital camera is to look at the battery material, how will charge, and how long will the cost in use and sitting on the shelf or in the digital camera.
A little I look in my purchase any digital camera I buy is to ensure that there is a common battery size. The reason is, no matter how you plan a photo shoot, things happen, you may have to resort to the old alkaline batteries solve your problems, then. Panasonic battery my first choice is a rechargeable battery, but you never know, this is a very good thing can find a new set of batteries.
There are several important factors to consider, rechargeable batteries is the best. The first is the amount of voltage, followed by long time, then the battery of the time; Four is charge (how long shelf life will be held responsible for the storage battery).
Here are a series of typical rechargeable batteries and their voltage output:
Ni-Cad rechargeable battery, 12 volts
Nickel metal hydride rechargeable batteries-1.2 to 1.5
Ni-ZN rechargeable batteries-160 volts
Standard alkalines is 1.5 volts
Also have a level a reference number of energy storage, from the ability to represent called milli ampere hour. These level general fleeing to 2100 from 750 from is high, the more the number of the battery capacity (higher digital better).
The Ni-Cad and nimh most common, almost every major brand battery multiple versions. The latest technology is Ni-ZN are excellent storage capacity and long shelf life. Many types of rechargeable batteries can be charging many times, but they didn't mention that drop down power amount of recharges x.
And this is the real factors to consider. Let us say that if you find new battery you can use about 100 photos before they go to the south. Recharges Numbers increase, reduce many pictures. Some can only continue to before they start, recharges loose the ability to completely costs. Clever cost is still good savings from an ordinary AA alkaline battery cost $1.15 and the comparable charge is $2.50, according to the figures from $5.00.
Recent Ni-ZN cost about $5 each request and take over 500 recharges in any losses before the injury charge ability. But they also play more voltage so for example your flash recycling half the time to complete the normal alkaline batteries. If you have 100 threw a set of alkaline, you should get at least 175 vote of Ni-ZN are the same size. Plus storage life N-ZN than any other choice.
Rapid turnover a flash can be a big problem, because it is a very painful, but when photographs in the interior, need to wait for two minutes of the flash is full of power. Or, if you are shooting a series of short a minute video and ran out of the juice in the middle is not a good thing.
So, based on the pricing and ability, if you can recharge the battery is more than 500 times more the highest price, they use more cheap long-term development. If they hold up close to claim 500 cost, well, you can do the math. This is a no brainer, Ni-ZN provide more voltage, better life, and more fees each battery.

When the diesel generators were gone, the reactor operators switched to emergency battery power. The batteries were designed as one of the backups to the backups, to provide power for cooling the core for 8 hours. And they did.
Within the 8 hours, another power source had to be found and connected to the power plant. The power grid was down due to the earthquake. The diesel generators were destroyed by the tsunami. So mobile diesel generators were trucked in.
This is where things started to go seriously wrong. The external power generators could not be connected to the power plant (the plugs did not fit). So after the batteries ran out, the residual heat could not be carried away any more.
At this point the plant operators begin to follow emergency procedures that are in place for a “loss of cooling event”. It is again a step along the “Depth of Defense” lines. The power to the cooling systems should never have failed completely, but it did, so they “retreat” to the next line of defense. All of this, however shocking it seems to us, is part of the day-to-day training you go through as an operator, right through to managing a core meltdown.
It was at this stage that people started to talk about core meltdown. Because at the end of the day, if cooling cannot be restored, the core will eventually melt (after hours or days), and the last line of defense, the core catcher and third containment, would come into play.
But the goal at this stage was to manage the core while it was heating up, and ensure that the first containment (the Zircaloy tubes that contains the nuclear fuel), as well as the second containment (our pressure cooker) remain intact and operational for as long as possible, to give the engineers time to fix the cooling systems.
Because cooling the core is such a big deal, the reactor has a number of cooling systems, each in multiple versions (the reactor water cleanup system, the decay heat removal, the reactor core isolating cooling, the standby liquid cooling system, and the emergency core cooling system). Which one failed when or did not fail is not clear at this point in time.
So imagine our pressure cooker on the stove, heat on low, but on. The operators use whatever cooling system capacity they have to get rid of as much heat as possible, but the pressure starts building up. The priority now is to maintain integrity of the first containment (keep temperature of the fuel rods below 2200°C), as well as the second containment, the pressure cooker. In order to maintain integrity of the pressure cooker (the second containment), the pressure has to be released from time to time. Because the ability to do that in an emergency is so important, the reactor has 11 pressure release valves. The operators now started venting steam from time to time to control the pressure. The temperature at this stage was about 550°C.
This is when the reports about “radiation leakage” starting coming in. I believe I explained above why venting the steam is theoretically the same as releasing radiation into the environment, but why it was and is not dangerous. The radioactive nitrogen as well as the noble gases do not pose a threat to human health.
At some stage during this venting, the explosion occurred. The explosion took place outside of the third containment (our “last line of defense”), and the reactor building. Remember that the reactor building has no function in keeping the radioactivity contained. It is not entirely clear yet what has happened, but this is the likely scenario: The operators decided to vent the steam from the pressure vessel not directly into the environment, but into the space between the third containment and the reactor building (to give the radioactivity in the steam more time to subside). The problem is that at the high temperatures that the core had reached at this stage, water molecules can “disassociate” into oxygen and hydrogen – an explosive mixture. And it did explode, outside the third containment, damaging the reactor building around. It was that sort of explosion, but inside the pressure vessel (because it was badly designed and not managed properly by the operators) that lead to the explosion of Chernobyl. This was never a risk at Fukushima. The problem of hydrogen-oxygen formation is one of the biggies when you design a power plant (if you are not Soviet, that is), so the reactor is build and operated in a way it cannot happen inside the containment. It happened outside, which was not intended but a possible scenario and OK, because it did not pose a risk for the containment.
So the pressure was under control, as steam was vented. Now, if you keep boiling your pot, the problem is that the water level will keep falling and falling. The core is covered by several meters of water in order to allow for some time to pass (hours, days) before it gets exposed. Once the rods start to be exposed at the top, the exposed parts will reach the critical temperature of 2200 °C after about 45 minutes. This is when the first containment, the Zircaloy tube, would fail.
And this started to happen. The cooling could not be restored before there was some (very limited, but still) damage to the casing of some of the fuel. The nuclear material itself was still intact, but the surrounding Zircaloy shell had started melting. What happened now is that some of the byproducts of the uranium decay – radioactive Cesium and Iodine – started to mix with the steam. The big problem, uranium, was still under control, because the uranium oxide rods were good until 3000 °C. It is confirmed that a very small amount of Cesium and Iodine was measured in the steam that was released into the atmosphere.
It seems this was the “go signal” for a major plan B. The small amounts of Cesium that were measured told the operators that the first containment on one of the rods somewhere was about to give. The Plan A had been to restore one of the regular cooling systems to the core. Why that failed is unclear. One plausible explanation is that the tsunami also took away / polluted all the clean water needed for the regular cooling systems.
The water used in the cooling system is very clean, demineralized (like distilled) water. The reason to use pure water is the above mentioned activation by the neutrons from the Uranium: Pure water does not get activated much, so stays practically radioactive-free. Dirt or salt in the water will absorb the neutrons quicker, becoming more radioactive. This has no effect whatsoever on the core – it does not care what it is cooled by. But it makes life more difficult for the operators and mechanics when they have to deal with activated (i.e. slightly radioactive) water.
But Plan A had failed – cooling systems down or additional clean water unavailable – so Plan B came into effect. This is what it looks like happened:
In order to prevent a core meltdown, the operators started to use sea water to cool the core. I am not quite sure if they flooded our pressure cooker with it (the second containment), or if they flooded the third containment, immersing the pressure cooker. But that is not relevant for us.
The point is that the nuclear fuel has now been cooled down. Because the chain reaction has been stopped a long time ago, there is only very little residual heat being produced now. The large amount of cooling water that has been used is sufficient to take up that heat. Because it is a lot of water, the core does not produce sufficient heat any more to produce any significant pressure. Also, boric acid has been added to the seawater. Boric acid is “liquid control rod”. Whatever decay is still going on, the Boron will capture the neutrons and further speed up the cooling down of the core.
The plant came close to a core meltdown. Here is the worst-case scenario that was avoided: If the seawater could not have been used for treatment, the operators would have continued to vent the water steam to avoid pressure buildup. The third containment would then have been completely sealed to allow the core meltdown to happen without releasing radioactive material. After the meltdown, there would have been a waiting period for the intermediate radioactive materials to decay inside the reactor, and all radioactive particles to settle on a surface inside the containment. The cooling system would have been restored eventually, and the molten core cooled to a manageable temperature. The containment would have been cleaned up on the inside. Then a messy job of removing the molten core from the containment would have begun, packing the (now solid again) fuel bit by bit into transportation containers to be shipped to processing plants. Depending on the damage, the block of the plant would then either be repaired or dismantled.
Now, where does that leave us?
・The plant is safe now and will stay safe.
・Japan is looking at an INES Level 4 Accident: Nuclear accident with local consequences. That is bad for the company that owns the plant, but not for anyone else.
・Some radiation was released when the pressure vessel was vented. All radioactive isotopes from the activated steam have gone (decayed). A very small amount of Cesium was released, as well as Iodine. If you were sitting on top of the plants’ chimney when they were venting, you should probably give up smoking to return to your former life expectancy. The Cesium and Iodine isotopes were carried out to the sea and will never be seen again.
・There was some limited damage to the first containment. That means that some amounts of radioactive Cesium and Iodine will also be released into the cooling water, but no Uranium or other nasty stuff (the Uranium oxide does not “dissolve” in the water). There are facilities for treating the cooling water inside the third containment. The radioactive Cesium and Iodine will be removed there and eventually stored as radioactive waste in terminal storage.
・The seawater used as cooling water will be activated to some degree. Because the control rods are fully inserted, the Uranium chain reaction is not happening. That means the “main” nuclear reaction is not happening, thus not contributing to the activation. The intermediate radioactive materials (Cesium and Iodine) are also almost gone at this stage, because the Uranium decay was stopped a long time ago. This further reduces the activation. The bottom line is that there will be some low level of activation of the seawater, which will also be removed by the treatment facilities.
・The seawater will then be replaced over time with the “normal” cooling water
・The reactor core will then be dismantled and transported to a processing facility, just like during a regular fuel change.
・Fuel rods and the entire plant will be checked for potential damage. This will take about 4-5 years.
・The safety systems on all Japanese plants will be upgraded to withstand a 9.0 earthquake and tsunami (or worse)
・I believe the most significant problem will be a prolonged power shortage. About half of Japan’s nuclear reactors will probably have to be inspected, reducing the nation’s power generating capacity by 15%. This will probably be covered by running gas power plants that are usually only used for peak loads to cover some of the base load as well. That will increase your electricity bill, as well as lead to potential power shortages during peak demand, in Japan.

Gigazineで、「27歳になると知能が低下する」という記事が注目されているようだ。
日本語訳：「一方、27歳になると推理力・思考速度・空間の具現化の3つの項目が著しく低下し始めていることが研究で明らかになったとのこと。」
げ、やべ、俺25歳、後2年だ。大学時代、もっと勉強しておけばよかったしくしく・・・と思って、元の英語の記事を読んでみる：
原文："The first age at which performance was significantly lower than the peak scores was 27 – for three tests of reasoning, speed of thought and spatial visualisation."
あれ？「著しく低下する」なんてどこに書いてあるの？じ～～～・・・・
・・・・もしかして、"was significantly lower than"を、「著しく低下する」って訳したのか？バカタレ！このsignificantlyは、「有意に」だ。データ取ってみたら、22歳がピークだったから、22歳とx歳の間に統計的な有意差があるかどうかを、xを23, 24, 25,...と増やしながら、年齢ごとに検定していって、x=27で、初めて、推理力・思考速度・空間視覚化の３つのテストで統計的に有意に（significantly）差が表れました、って意味だろ。
心理や教育のような人間を対象とする科学の分野の学術論文で、"significantly"とか"significant"って書いてあったら、それは、統計的な検定を行った時の「有意に」とか「有意な」という意味に決まっているではないか！論文中で"significantly"に差が出ましたって書いておいて、検定やっていなかったら「ちゃんと検定やってください」って査読者にはねられて、論文が通るわけがないのだから。
俺、心理も教育も全然専門外で、単に情報系大学院出ただけだけど、これぐらいはわかるぞ。「著しく」じゃなくて「有意に」であることがわかったら、「あー、そんなもんだろうなぁ」、と、納得できる。一般的に年を取ると知能が低下することは知られているが、具体的に何歳でどれぐらい知能が低下かを計測するのは、かなり難しい問題のはずだ。ある一人の知能テストを継続的に受けさせて、年をとったところで点数が下がったとしても、偶然である可能性もあるし、計測した人がたまたま、「年齢と知能テストの相関がとても激しい特異体質」であったかも知れず、一般の人がどうこう、ということについては何も言えないからだ。
この論文は、2000人について、知能テストを継続的に受けさせて（それ自体がものすごいことだと思う）、年齢以外に知能が低下した原因が考えられないような状況を作り出した。そこまでして、やっと、「27歳は、22歳と比べて知能が低いという統計学的な証拠が出ました」ということが、いえたという印象。頑張ったなぁ、力技の論文だなぁ、マジメに検証して偉いなぁ、と思う。
世の中ね、そんな簡単に「著しい」なんていえないんですよ。特に一般的に常識になっていることほど、そう。「女子は感情的、男子は理論的」とか、「一人っ子はわがまま」とか、常識的に信じられているけど、それをサイエンスとしていうためには、すごく限定された設定でものすごくたくさんアンケートをとって、ようやく言えるか言えないかってところ。そう簡単に「著しい」差なんて出たら苦労しないわ、バカタレ。
追記：
「心理や教育のような人間を対象とする科学の分野」でなくても、自然科学系なら一般的に"significantly"は「統計的に有意」の意味だろう、という指摘があったけど、以下の理由により、こういう表現をしました。
・分野によっては、「統計的に有意」という概念が有用でない場合がある
例えば、物理・数学・情報科学などで、何か命題を証明するときに、「実験してみて統計的に有意ですから、この数式は正しい」ということは普通やらず、数学的な操作を繰り返して証明する。こういう風に、統計や検定が関係ないということが明らかな文脈では、"significantly"は「統計的に有意」以外の意味を持ってもおかしくないので、限定しておいたまでです。

私はプロとして最近確定申告に行き税務署員とのつかみ合いの押し問答もした音楽作家です。↑の記事を見て技術的な面で思ったことがあったのでひとこと。
Perfumeはオートチューンと言われるヴォーカルのピッチ(音程)を修正するソフトを使っている。↓のリンク先の写真をよく見て頂きたい。
http://content3.e-frontier.co.jp/products/antares/at5/images/at5_auto_l.jpg
このオートチューンと言われるソフトだが、どんなに下手に歌っても強制的にピッチ(音程)を維持してくれるのだ。本来なら、人間らしく修正する為の使い方をするのだが、
つまみをいじってぴっちり合うように強制的に歌のデータを修正させている。写真で言うとretune speed("ド"というメロディなのに下手に歌ってしまった音程が"ド#"だったら、ピッチをどれだけ本来の"ド"に近づけるかの値)・Humanaize(人間らしくする値)を0の値する。すると強制的に、言い方を変えるとピッチ(音程)が完璧な"ド"だからロボットのような聞こえ方になったりする。たまに歌がケロケロ聞こえるのは、ソフトが強制的に本来のピッチ(音程)に戻そうとするからだ。
説明がわかりづらかったら申し訳ないのだが、言ってみればPerfumeは機械の声。人間味はいらない(中田ヤスタカ氏のプロデュース以前は含まない)。そんなトコロが面白いし快感だ。
極端だが初音ミクはその反対。
初音ミクというヴォーカルを扱うクリエイターの方々はいかに"人間に近づけるか"に技術と時間をつぎ込んでいるのだとおもう。発音の具合、タイミング、ビブラートの調節などなど。自分は少し触ってみたがとても使えなかった。"使えない"と言うのは音楽的にではなく、作業時間と労力にだ。当然本業で音楽をやっているのでヴォーカルは人間の歌を録っている。仕事として(もちろん音を楽しんで)歌を録る(初音ミクだと作る、息を吹き込むと言えばいいかな)作業なのでクオリティとスピード、作業時間が大切。そういう点で使えなかった。
初音ミクはソフトやハードが技術的に進歩し、初音ミクを扱う人間の技術も向上する。いずれ一聴しただけでは人間との区別がつかなくなる日が必ず来る。
と言った彼が本当の人間の歌声じゃない歌声の楽曲を気に入って購入する日も、そう遠くはないと本気で思う。
今の初音ミクとPerfumeの状況はちょうどお互いの向かっている方向がクロスしていて友達以上、恋人未満。だけどいずれ親戚以上。
無限エネルギー源をもととするエネルギー変換能力の向上である。エネルギー源は無限にあるので、変換効率すなわち出力の向上を狙えば良い。
有限エネルギー源を最大限使用して、短時間に出力へとエネルギー変換する能力である。ここを突き詰めると ATP/CP の貯金を増やすための筋肉量の増加を狙うことになる。筋肉量が増えるので当然、時間当り変換容量も増えることになる。
それぞれのエネルギー変換能力は筋肉量に依存するのだが、代謝系が異なるので両方の能力を同時に得ることはできない。それぞれの代謝系に対して効率良くアプローチする必要がある。

こんばんは、しがないニコ厨です。
さてさて、EXIT TRANCE PRESENTS CODE SPEED アニメトランスBESTという商品が市場デイリーランキングで、
7/22（日） 5位
7/23（月） 3位
7/24（火） 1位
7/25（水） 1位
と推移していました。昨日からランキングが自動化されましたね。
このアルバム、なぜ売れたかっていうとレビューにもあるように"組曲『ニコニコ動画』"を真似たのかと見紛うほど、
曲目リストが被っているかららしいですね。 あれだけ中毒性のあるものだとCDで欲しくなりますもんね！
ぼくは、昨日はてブ経由でニコニコ動画で行われているオープンソース現象 組曲『ニコニコ動画』
を読んで、そこから見事にハマり、だいたいの動画を視聴しました。
歌ってみた系、素材系、元曲系などなど、ほとんどの動画で上記の商品が市場の上位に上がっていました。
まあ実際に売れているので、当たり前と言えば当たり前か。
でも、左上に来るのを4回くらい連続で見たときは、さすがに違和感を感じました。
今、ニコニコ市場はプレミアムユーザーが商品の登録・削除を行うシステムになっています。（一般なので見たことない）
