山东省青岛市二院网上预约挂号Researchers from the Third Military Medical University in China said they have developed a cheap, easy test to determine a patient#39;s blood type in a matter of seconds with nearly perfect accuracy.我国第三军医大学的研究人员日前表示,已研制出一种鉴定病人血型的低成本简易测试,准确率接近百分之百,耗时数秒。The new assay is able to pinpoint whether a person is type A, B or O in just 30 seconds, and determine the blood type in full detail in about two minutes.这项新测试能够在仅仅30秒内就准确鉴定某人的血型是A、B还是O,并在约两分钟内鉴定血型的所有详细情况。Results on the new device were published in Science Translational Medicine.《科学转化医学》杂志刊登了这一血型鉴定新方法的研究结果。To create the test, the researchers took advantage of chemical reactions between blood serum proteins and a widely-available dye called bromocreosol green.为了实现这项测试,研究人员利用了血浆蛋白和一种使用广泛的染料溴甲酚绿之间的化学反应。Each test paper strip was also equipped with antibodies that recognized different blood type markers, such as A or B antigens, which can be found on the surface of red blood cells.每张试纸也都配备有可以识别匹配不同血型的抗体,例如他们可以在血红细胞的表面发现A型或者B型血的抗原。When a drop of blood was applied, the results appeared as visual color changes in the observation window of the paper strip: teal if a blood group antigen was present in a sample and brown if not.当血滴在测试条上面,会有肉眼可以观察到的颜色变化,这些颜色变化会在测试纸的观察窗变化范围之内,若提交样本是血型匹配的抗原,为蓝绿色,如果没有为棕色。The method was tested on 3,550 samples of human blood with results of more than 99.9% accuracy, and the only inconsistencies occurred in trials with highly uncommon blood types.研究人员已用该方法对3550份人类血样进行测试,结果准确度超99.9%,在试验中唯一失败的案例是由于血型罕见。 /201703/500915青岛妇科知名医院The 11,700-year-old Holocene epoch is over. We#39;re now living in the Anthropocene epoch.长达11700年的全新世结束啦。我们如今正生活在“人类世”纪元。You don’t need to be paying much attention to the world around you to know that humans are having a massive influence on the planet, but our influence is now on the way to being officially recognised in geologic terms.无需劳神费力,我们都能感受到人类对地球产生的巨大影响。如今,地质学界打算用地质术语来确认这些影响。The 11,700-year-old geological Holocene epoch has ended, scientists say, and we’re now living in the Anthropocene: an era defined by humanity’s influence on the world around us.科学家表示,长达11700年的全新世已结束,我们现在正生活在“人类世”:即人类活动对地球施加影响的时代。In fact, unless you’re over the age of 66, you’ve always been living in it. A 35-strong team of international researchers from the Working Group on the Anthropocene voted 30-3 (two were absent) in favour of the epoch shift, and the starting date is 1950.事实上,66岁以下的人自出生起就生活在这个纪元了。一由35位国际顶尖研究者组成的“人类世”工作小组开展了纪元更变与否的投票,投票结果以30比3(有两位研究人员缺席)的压倒性优势宣布地质纪元进入“人类世”,并将开始时间确定为1950年。The date isn’t random: it matches when the first nuclear tests created a new stratum in the planet’s surface.这个日期可不是随便定的:它与首批核试验对地质表面造成影响的时间相符。Actually, it won’t necessarily be nuclear tests that ended the Holocene. Humanity’s impact on the planet is so great that we’re left “spoiled for choice” in terms of which particular signal to choose.实际上,核试验并非结束全新世的唯一必要条件。人类活动对地球的影响是如此深刻,可供选择的因素简直多到让人“眼花缭乱”,很难定夺到底哪一因素起了决定性作用。Plastic pollution, soot from power plants, concrete and even domestic chicken bones were considered possible contenders.塑料污染,发电厂煤烟,钢筋混泥土,甚至是家养鸡的骨头都被列入可能的影响因素。“The radionuclides are probably the sharpest – they really come on with a bang,” said the Working Group’s chair Jan Zalasiewicz, of the University of Leicester. “But we are spoiled for choice. There are so many signals.”工作组主席、莱斯特大学的简#8226;扎拉斯维奇表示:“放射性核素大概是这其中最厉害的一个因素—— 放射性核素真是伴随着‘砰’声来临,但是可供选择的因素太多了,许多因素都对地质产生了巨大影响。”Now that the vote has been done, we’ll see a few years of site sampling to figure out the best Global Standard Stratigraphic Age (GSSA) to date the start of the Anthropocene, which will then be presented to the International Commission on Stratigraphy.纪元变更的投票结束后,工作组在未来几年会利用现场勘测数据计算出最佳的全球标准低层年龄(GSSA),并确定“人类世”的开始日期,届时会把研究结果呈递国际地层委员会。It will then need ratification from the Executive Committee of the International Union of Geological Sciences.随后还需要国际地质科学联合会的执行委员会正式认可研究结果。So it’s not official yet, but Zalasiewicz believes the team has a “pretty good case” to present.所以现在官方其实还未正式承认人类世的开始,但扎拉斯维奇相信他的团队递交的案例非常棒。“The significance of the Anthropocene is that it sets a different trajectory for the Earth system, of which we of course are part,” he explained.他解释说:“‘人类世’的意义在于,它让地球体系步入了一个与众不同的轨道,在这个新纪元里,人类也参与其中。”“If our recommendation is accepted, the Anthropocene will have started just a little before I was born. We have lived most of our lives in something called the Anthropocene and are just realising the scale and permanence of the change.”“如果我们的提议通过审核,‘人类世’在我出生前不久就开始了。我们大半辈子都生活在‘人类世’中,而且刚意识到地质纪元变更的规模和持久性。”In other words, geologically at least, there will be no denying the influence mankind has had on the planet. And it’s a hard one to put a positive spin upon, no matter how you frame it.换句话来说,至少从地理的角度看,我们将无法否认人类对地球造成的影响。而且无论我们如何定义都很难将这个影响扭转成正面影响。 /201609/466794If you plan on travelling abroad, make sure to protect your iPhone. Replacing your device could prove quite costly outside of the ed States, according to a report by Deutsche Bank.如果你计划出国旅游,那么请一定要保管好你的iPhone。根据德意志日前发布的一份报告显示,在美国之外的国家和地区,换一个手机已经被明是非常昂贵的了。The study, helmed by strategist Jim Reid, compared the price of purchasing an Apple iPhone 6 and 6S - the 4.7-inch screen, 16GB models - in 27 different countries.这项研究是由高级策略师吉姆·瑞德负责的,比较了27个国家和地区4.7英寸、16G的iPhone 6和6S的售价。;Don#39;t lose your phone while away in Brazil, India, Sweden, Denmark or Italy as a new iPhone is most expensive there,; Reid#39;s team wrote in the research note.瑞德的团队在研究报告中写道:“千万不要在诸如巴西、印度、瑞典、丹麦或者意大利这些国家丢失你的手机,因为在哪些地方,一台新的iPhone是全世界最贵的。”Brazil holds the highest price tag in the report for both iPhone models. The iPhone 6 will set a buyer back about 1, while the 6S model costs about ,164.报告显示,这两款iPhone在巴西售价最高,iPhone 6要花费约931美元,而iPhone 6S的售价约为1164美元。In the US consumers pay around 8 for the Model 6 and 7 for the iPhone 6S. Prices for the smartphones in Japan, Hong Kong and South Africa are also on the lower end.消费者在美国购买同款iPhone 6仅需付约598美元,购买iPhone 6S仅需707美元。这两款智能手机在新加坡、日本、香港和南非的售价也比较低。The Chinese mainland comes out as the 18th expensive place to buy the 6S model among the 27 countries and regions.该款iPhone 6S在中国大陆的售价在27个国家和地区中排在第18位。Reid#39;s report said his team ;tried to ensure that all taxes and surcharges are included; so the figures are comparable, but there could still be some variation depending on discounts and local fees.瑞德的报告中还表示,他的团队尝试着确保把所有的税金及附加费包括在内,因此这些数字是具有可比性的,但是仍有一些取决于折扣和地方性收费的变化。 /201606/447675青岛做孕前检查要多少钱

青岛做流产多少钱在青岛查妇科,哪家医院好点Google Inc is in discussions with NetEase Inc, China#39;s second-largest online games provider, to bring its Google Play mobile app store to the Chinese mainland, according to The Information, a US news portal, which cited people familiar with the matter.美国新闻门户网站The Information近日援引知情人士消息称,谷歌公司正与中国第二大在线游戏提供商网易公司磋商,欲将谷歌旗下的移动应用商店谷歌Play引入中国大陆。Google and NetEase did not respond to requests for comment amid the buzz that Google may be mulling a comeback in the world#39;s largest mobile internet market.谷歌和网易两家公司目前均未对有关谷歌可能会考虑在全球最大的移动互联网市场东山再起的置评作出回应。Sandy Shen, a Beijing-based research director at technology consultancy Gartner Inc, said forming a partnership with local players could help Google get a green light from the Chinese government.技术咨询公司高德纳北京研究主管沈哲怡表示,与本土公司合作有助于谷歌获得中国政府的许可。The Cyberspace Administration of China issued a new regulation in January saying app store operators need to register with the local government before rolling out services.网信办今年1月发布新规称,应用商店运营商在推出务前需在地方政府处备案。;That#39;s perhaps why Google is reportedly considering a joint venture. NetEase can offer lots of help in government relations,; she said.沈哲怡说道:“这也许是有报道称谷歌考虑开办合资公司的原因。网易在政府关系方面能提供许多帮助。”Wang Xiaofeng, a senior analyst at Forrester Research Inc, says any relaunch of Google Play will be welcomed by Chinese users because the app store still has a strong reputation in the country.弗雷斯特研究公司的高级分析师王晓峰表示,谷歌Play的重返肯定会受到中国用户的欢迎,因为该应用商店在中国仍旧有着出色的声誉。The move also came after Apple Inc raked in millions of dollars from China. In the third quarter of 2016, Chinese consumers spent .7 billion at Apple#39;s iOS mobile app store, more than five times what they spent just two years ago.这一举动也是在苹果公司从中国市场获得数百万美元收益之后开始进行的。在2016年第三季度,中国消费者在苹果的iOS移动应用商店共计花费了17亿美元,这一数字为两年前的5倍。 /201702/493344青岛市好一点的妇科医院青岛市哪家医院可以做四维
