盐城/市月经不调多少钱滨海县治疗肛周囊肿多少钱When it comes to weird sea-creatures, octopuses arehard to beat.说到怪异的海洋生物,那就的非章鱼莫属了。Theres the well-known ink-squirting defensesystem, the bird-like beak, and the eight tentacles with theirdouble rows of suckers.因为他们有闻名的喷墨防御系统,有像鸟儿一样的嘴巴,以及八条带着两行吸盘的触角。Whats less well known is that octopuses have more than one heart.没那个为人所知晓的是,章鱼不只有一个心脏。They have three, to be exact, each one crucial to maintaining the robust blood pressure that allows octopuses to be active hunters and powerful swimmers.确切的说,它们有三个!每一个对于章鱼拥有强健的血压都至关重要,因为它们能让章鱼成为敏捷的猎手,成为游泳健将。Human hearts have two main jobs.人类的心脏有两大功能。One is to pump blood to the lungs, where it dumpscarbon dioxide and picks up oxygen.一是将血泵到肺中(肺是排除二氧化碳,吸收氧气的地方);The second is to distribute freshly oxygenated blood to therest of the body.二则是将新鲜的含有氧气的血液传输到身体的其它部位。Making sure enough blood gets to the lungs is so important, in fact, that two of the humanhearts four chambers are reserved solely for that task.事实上,确保有足够的血进入肺部是很重要的,而这个任务是由人类心脏的4个腔中有两个来单独完成的。Octopus hearts solve the circulation problem a bit differently.章鱼的心脏解决这个(血液)循环问题就有点不一样了。They have one main heart,called the systemic heart, and two smaller hearts located near their gills.它们有一个主心脏叫系统心脏,还有两个心脏要小点且位于腮附近。The two smaller heartsperform the same task as the right side of the human heart.这两个小点的心脏(的功能)就跟人心脏的右边部分功能是一样的。They pump blood to the gills where it dumps waste and loads up on oxygen, then pump the oxygen-rich blood back to the main heart.它们将血泵到排除废物收集二氧化碳的腮里,在将含有丰富氧气的血液泵回到主心脏。The main heart then pumps the refreshed blood through the octopuss body.主心脏接着就会将焕然一新的血液泵到章鱼的身体。Besides having three hearts, the octopus circulatory system differs from the human systemin one other way.除了有三个心脏外,章鱼的循环系统在另一方面也和人类的不一样。Human blood contains the protein hemoglobin, which helps it absorb oxygen and causes its red color.人类的血液含有含蛋白质的血红蛋白,它会帮助吸收氧气,并使血液呈红色。The blood coursing through the three hearts of the octopus is blue,thanks to a different protein called hemocyanin.血液流经章鱼的三个心脏就成了蓝色,这多亏了一种叫血蓝蛋白的蛋白质。Octopuses are rather shy, so despite their blue blood they are not exactly kings of the sea.章鱼是很害羞的,所以尽管它们有蓝色血液,却并不能使之成为真正的海洋之王。But theres no denying that theyve got a lot of heart.但毫无疑问它们是“太有心”了! 201412/350752盐城协和医院流产多少钱 Young trevally, they dart for the fish, causing them to panic and break ranks.澳洲鲹鱼飞快地冲向鱼群,恐慌的鱼群四下逃散。By putting themselves in the midst of the shoal, the sharks are in a perfect position to exploit the chaos.而这对等待在浅滩的鲨鱼来说,是浑水摸鱼的好机会。For a hungry lemon shark, no water seems too shallow.一条饥饿的柠檬鲨可以在任何浅水中活动。The sharks are able to use these special tactics to feed inshore, because of the rhythm of the tides, which change conditions every few hours.鲨鱼们这种独特的近岸狩猎策略是为了适应每几个小时就发生一次的潮汐,适应周而复始的变化而发展出来的。The cycle of day and night also has a dramatic effect on everything that lives on the reef.还有日夜的循环,也能产生出戏剧性效应,进而影响着珊瑚礁中的每个生物。 201411/341639江苏省东台市人民医院流产手术多少钱

But if Harish Bhaskaran of Oxford University is right, their days may be numbered. The essential feature of LCDs is that the pixels in them switch between amorphous and crystal-like phases, which changes their optical properties. In a paper in this weeks Nature, Dr Bhaskaran and his colleagues describe something similar in a solid material. At the least, that would stop the messy abstract-impressionist patterns which happen when an LCD is dropped too hard. At most, it might open up a new range of applications, from clothes that change colour to dimmable windscreens.液晶显示屏是一项成熟而广泛应用的技术。但如果牛津大学的Harish Bhaskaran的想法实现,液晶屏的好景也就没几天了。LCD的基本特征是其像素在非晶相和类晶相间转化,因此改变其光学性质。在本周的《自然》杂志上,Bhaskaran士及其同事陈述了一种类似的固体材料。至少该材质可以防止当LCD猛烈坠地后产生麻烦的抽象印象派图案。最理想情况下,它会有新的应用范围,从变色布料到可调光挡风玻璃。Solid phase-change materials are aly used to store data in optical memory disks. They are also being considered for use in memory chips, because the switch between amorphous and crystalline states alters their electrical properties in ways that can store electronic bits of data. Dr Bhaskaran, though, has shown that thin enough films of the right sort of material can be made to change colour, too.固态相变材料已经用于在光储存盘中储存数据。也可能被用于记忆芯片,因为其非晶态和晶态之间的转变也改变了其电学性能,因此他们能储存电子数据。然而,Bhaskaran士展示了一种特定材料膜,在足够薄的情况下也可以改变颜色。This property would make them suitable both for displays that rely on reflected light (so-called electronic paper) and the older, backlit sort that rely on transmitted light. The resulting displays would be thin and could be flexible if printed on the right material—increasing the range of applications they might be used in. And they would consume little power, since energy need be used only when a pixel has to be flipped from one phase to another.这一性能将使其适合于反射光显示(所谓电子纸)和早期的依赖透射光的背光显示。所得显示屏不仅薄,而且铺在合适材料上时非常灵活,增加了其应用范围。而且它消耗的功率更少,因为这种材料只需要在变相的时候消耗能量。The researchers material of choice is an alloy of germanium, antimony and tellurium. Both the crystalline and the amorphous phases of this substance are stable at any temperature a device is likely to experience, and thin films of it are more or less transparent. The power needed to effect the phase change could be fed to individual pixels by electrodes made of indium tin oxide, which is also transparent.研究人员选择的材料是镓、锑和碲合金。这一物质的晶态和非晶态在任何设备适用温度下都很稳定。其薄膜也几乎透明。要激发相转变所需的能量可以由透明的铟锡氧化物电极向单个像素提供。The colour of a pixel would depend not only on its phase, but also on its thickness, which would affect the way light waves being reflected within it interfere with one another, cancelling out some frequencies while amplifying others. (The effect is similar to the creation of colours by a thin layer of oil on a puddle.) Generally, the alloy layer needs to be thinner than 20 nanometres for that to happen.单个像素的颜色不仅取决于其相态,也同其厚度有关。厚度会影响光波在两个像素间界面处的反射,削弱部分频率,加强其他频率。(此效应类似于池塘表面薄油层产生的色。)一般来说,合金层需要薄于20 nm才会发生这一现象。To demonstrate their idea, the researchers sprayed films of their alloy onto pieces of silicon, quartz and plastic. They then used a device called an atomic-force microscope, which has a tip a few nanometres across, to apply appropriate electric currents in a grid pattern across the films surface. This grid mimicked an array of pixels, creating a stable pattern. The result, as their picture of a Japanese wave shows, is a recognisable image—if not, yet, a perfect one.为了明其观点,研究人员将其合金铺覆到硅,石英和塑料上。然后他们使用所谓原子力显微镜的设备来施加合适的电流在横穿膜表面的网格上。原子力显微镜尖端仅有几个纳米大小。网格模仿像素排列,产生稳定的模式。他们对日本电波的拍摄结果是一个可识别的图像,即便不可识别,也是非常完美的。Adding the indium-tin-oxide electrodes is a more complicated process, but to show it can be done in principle, Dr Bhaskaran has made a single pixel this way. Whether his idea will get off the lab bench and into the shops remains to be seen. It is by no means the only suggestion around for a new generation of display screens. But it looks plausible.加入铟锡氧化物电极是更为复杂的过程,但是可以从原理上展示其过程。Bhaskaran用这种方式制备了单个像素。他的想法能否从实验室走进商用还是未知。这绝不是新一代显示屏的唯一方案,但颇得看好。翻译:赵兴昊译文属译生译世 /201505/377287盐城协和医院产检费用

盐城第一医院治疗月经不调多少钱 听力参考文本:Last week I discussed a new bill that would make it easier for citizens to get absentee ballots in Michigan, a bill sponsored by a Republican state representative, Lisa Posthumus Lyons, and enthusiastically supported by Secretary of State Ruth Johnson.Shes also a conservative Republican and Michigans chief elections official. The bill is scarcely radical; it would merely allow any voter who wants an absentee ballot to get one. Two-thirds of the states aly allow what is called ;no-excuse; absentee voting.In fact, all those states also allow early voting, meaning that on certain days before the election, the polls are open to allow people to vote who aly have made up their minds.This both encourages turnout and reduces lines on Election Day.Three states – Colorado, Washington and Oregon – require everyone to vote absentee. As it now stands, Michigan is definitely backward when it comes to helping citizens participate in democracy.But unfortunately, Republican leaders in the Legislature have exceeded my worst expectations. Senate Majority Leader Arlan Meekhof made it very clear he has no interest in doing anything to help more people vote.;They should be responsible enough to make sure they get to their own polling places,; he said. ;I think thats the least we can ask.” He also said he feared ;fraud and abuse,; although there has been no evidence of that reported in any of the thirty-six states that are more voter-friendly than Michigan.And State Senator Dave Robertson, a former insurance salesman from Grand Blanc, was, if anything, worse. Robertson is the chair of the Elections and Government Reforms Committee, and he made it clear that he will do everything he can to sabotage Lyons bill if it makes it to the senate.Not only did he say he would oppose it, he said he wouldnt even allow hearings to consider this, hearings in which he and his fellow senators could hear testimony about how open absentee balloting has worked in other states.Why does he feel this way?Well, Robertson was at first largely incoherent, called Election Day a “focal point” he didnt want to diminish, but then gave a fantastically incredible reason. He said no-fault absentee voting would unfairly handicap candidates because they wouldnt have enough time to reach those voting early.If he really believes that, he may be the only person in the nation who thinks our campaigns are too short. The truth is that he and Meekhof dont want to allow this because they are indeed afraid more people would vote. They know that higher voter turnout tends to favor Democratic candidates, which they are determined to prevent.But it isnt politically acceptable to say they want to keep people from voting, so they make up hypocritical excuses instead. The fact is that no-excuse absentee voting is highly unlikely to change very much, especially in our heavily gerrymandered legislature.And it is encouraging that two principled Republican women have had the integrity to come out in favor of doing what is right and helping more people vote.It would be nice if they could be supported by a little citizen outrage against the men who want to prevent more people from participating in democracy.Jack Lessenberry is Michigan Radios political analyst.
