青岛有哪些地方可以做四维彩超青岛一个月打胎要多少钱It isn’t easy to track down a positive word about the Middle East these days. Then again, Juan Cole is not your typical observer. A professor of history at the University of Michigan, he is also a prolific and popular blogger on current affairs. An American, he spent part of his childhood in France and Ethiopia. A left-leaning idealist, he comes across as far more optimistic than the dour Occupy crowd. A cosmopolitan in constant touch with 20-somethings, he seems to be addressing boomers in his latest book, “The New Arabs,” which is replete with explanations that digital natives would never need. (Don’t know what the “meatspace” is? Read on.)在如今,关于中东,你很难听到什么正面的说辞。此外,胡安·科尔(Juan Cole)可不是一般的观察家。他是密歇根大学的历史教授,也是既高产又受欢迎的时事客写手。他是美国人,但童年时期曾经在法国和埃塞俄比亚生活过。他是个左倾的理想主义者,比那些阴沉沉的“占领者”们要乐观得多。他是个世界主义者,还经常和20多岁的人打交道,他的新书《新阿拉伯人》(The New Arabs)中有很多注释是数码一代根本不需要的,所以更像是对婴儿潮一代发表的讲演——你不知道什么叫“肉体空间”(meatspace,来自赛朋克和科幻小说术语,指和“网络世界”“虚拟世界”相对的“现实世界”——译注)?接着往下读。“The New Arabs” chronicles the heart-stirring youth revolts in Egypt, Tunisia and Libya. Early on, Cole does some defying of his own. “The rise of the Internet,” he notes, “may not have been as central to these social movements as some Western press coverage assumed.”《新阿拉伯人》按时间顺序记载了发生在埃及、突尼斯和利比亚激动人心的青年反抗运动。一开始,科尔的观点有些矛盾,“互联网的崛起在这些社会运动中所起的作用,或许并不像某些西方媒体所报道的那样重要,”他指出。To be sure, Cole affirms that online networks dramatically amplified the reach and resonance of protesters’ demands for state accountability. Take the iconic story of Mohamed Bouazizi. Ripped off and slapped by a government employee, the young Tunisian self-immolated in front of his local city hall, igniting the first of the uprisings. Internet buzz propagated the myth that Bouazizi had graduated from college, making an educated underclass think of him as one of their own and thus take up his cause. In fact, because of poverty, Bouazizi had not even finished high school. Nor was his name Mohamed; it was Tarek. Ah, the baptismal power of social media.科尔认为,抗议者们要求政府更有责任感,而网络也确实极大地扩展了他们的影响力,为他们带来更多共鸣。就拿已经成为典型的穆罕默德·布瓦吉吉(Mohamed Bouazizi)的故事来说吧。这个突尼斯年轻人被政府官员敲诈和掌掴,于是在当地市政厅门前自焚,成为起义的导火线。互联网迅速放大了布瓦吉吉的神话,说他是大学毕业生,这会令一个受过教育的下层社会成员觉得他是自己人,想继承他的事业。事实上,由于贫穷,布瓦吉吉连中学都没念完。他的名字也不是穆罕默德,而是塔里克(Tarek)。啊,这就是社交媒体的洗脑力量。Still, the Internet is only one strand of a much broader web that Cole weaves. His is a huge challenge: to map the outbreaks of tumult that have crisscrossed Tunisia, Egypt and Libya over the past decade. Strikes, b shortages, lack of water, inflation, unemployment — all on top of a generational thirst for personal autonomy and political liberty. It makes for chaotic ing. Policy wonks get their fill. The rest of us need patience.不过,科尔编织了一张更大的网络,互联网只是其中一环。他的网络是一个巨大的挑战——要描绘出过去十年内突尼斯、埃及和利比亚爆发的各种骚乱。罢工、面包短缺、缺水、通货膨胀、失业——这一切都落在渴望个人自治与政治自由的一代人头上。这些事件令这本书充满混乱。热衷政治的读者会心满意足,而其他读者则需要耐心。Yet Cole does eventually deliver. In a particularly vivid section, he describes the breath#173;taking pluralism of those who put themselves on the front lines to protect Egyptian demonstrators. Coptic Christian youths served as bodyguards for their Muslim peers. They knew that as Muslims prostrated during Friday prayer — the prelude to pouring into the streets — their bowed heads would invite attack. Soccer thugs found new purpose as bouncers around Tahrir Square. Muslim Brothers, too, shielded secular friends, especially on the day some jobless tour guides rode camels straight into crowds of activists.但是科尔最终还是做到了。他描述了那些站在最前列去保护埃及抗议者的人们,这是激动人心的多元主义,这个部分也格外生动。埃及信奉基督教的年轻人为他们的穆斯林伙伴充当保镖,因为他们知道穆斯林在周五要匍匐礼拜——这是他们走上街头抗议的序曲——而穆斯林们都低着头,军警会攻击他们。足球流氓们有了新的的活动:在塔里尔广场附近保护抗议者。穆斯林兄弟会也去保护他们世俗的朋友,特别是在有些失去工作的导游骑着骆驼径直冲进行动分子人群的那一天。The book hits its stride in Libya. Catching revolution fever after Tunisia and Egypt, young Libyans took advantage of the world’s eyeballs. Their online savvy combined with old-fashioned lobbying to secure a no-fly zone above Libya. When one of Qaddafi’s sons shut down Internet access, he was outwitted: Using their cellphones, dissenters called a special number that automatically turned their voice mail messages into tweets.这本书对利比亚的报道也很精。年轻的利比亚人目睹了突尼斯与埃及的革命狂热,也想趁机利用世界的关注。他们把网络智慧和老式的议会游说结合起来,保利比亚上空有了禁飞区。卡扎菲的一个儿子关闭了互联网,但他被人们的智慧击败了。不同政见者们用手机拨打一个特殊的号码,可以自动把他们的语音信息传到Twitter上去。Ultimately, though, it was rebels in the fields, factories and alleys who kept Qad#173;dafi and his gang on the run. Ramadan, the Muslim month of fasting, stopped nothing. Sunset marked an opportunity to refuel with food and arms. Dusk prayers served “as a signal to begin the uprising,” even among those who were secretly fighting to separate mosque and state.但最后,还是发生在农田、工厂与小巷中的抗议行动导致了卡扎菲和同党的下台。穆斯林的斋月也没有导致事态停止。日落后,人们就有机会补充食物和武器。晚祷成了“起义的信号”,甚至那些密谋让伊斯兰教与政府分离的人们也遵守这个信号。For all of the “liking” and “sharing,” Cole shows that the revolution’s most important triumphs took place in the sphere of physical effort — the “meatspace.”至于社交网络上那些“赞”和“分享”,科尔的书表明,革命最重要的胜利都是现实社会中的努力所带来的——也就是我们前面所说的“肉体空间”。But to what end? Is the Middle East truly transforming? Tunisia offers a clue. In the wake of the uprisings, “over a hundred new political parties had been founded.” By contrast, the previous regime “allowed only eight.” And those parties will be busy. A “celebrated” Tunisian rapper supports Shariah law. A “prominent intellectual” scorns Shariah as the product of Judaism and therefore a travesty. Above all, a teacher observes, “Now we have to learn democracy.”但是胜利到什么程度呢?中东真的改头换面了吗?突尼斯的情况可以提供线索。起义之后,“成立了100多个新政党”。相反,之前的政权“只允许八个政党存在”。这些政党将会很忙。一个“有名的”突尼斯说唱歌手持伊斯兰教法。一个“著名知识分子”鄙视伊斯兰教法,称其是犹太教的产物,是拙劣的模仿品。一个教师指出:“现在我们必须学习民主。”Unorthodox wisdom for an era in thrall to instant gratification.对于一个受困于当下满足感的时代来说,这堪称异端的智慧。 /201409/325598青岛医院人流手术那比较好 A doughnut created in a lab and made of silk on the outside and collagen gel where the jelly ought to be can mimic a basic function of brain tissue, scientists have found.科学家发现,实验室里制造的一个类似甜甜圈的东西,可以模仿脑组织的一项基本功能。这个圆圈的环状部分由丝材料制成,圈里面填的是胶原蛋白凝胶。Bioengineers produced a kind of rudimentary gray matter and white matter in a dish, along with rat neurons that signaled one another across the doughnut’s center. When the scientists dropped weights on the material to simulate traumatic injury, the neurons in the three-dimensional brain model emitted chemical and electrical signals similar to those in the brains of injured animals.生物工程师在培养皿中制成了相当于原始灰质和白质的材料,其中用了大鼠神经元,这些神经元能通过圆圈中间的物质相互交换信号。当科学家让重物掉到这个圆圈上,以模拟创伤性损伤时,这个三维大脑模型中的神经元释放出了化学信号和电信号,与受伤动物的大脑释放的信号类似。It is the first time scientists have been able to so closely imitate brain function in the laboratory, experts said. If researchers can replicate it with human neurons and enhance it to reflect other neurological functions, it could be used for studying how disease, trauma and medical treatments affect the brain — without the expense and ethical challenges of clinical trials on people.专家们表示,这是科学家首次能在实验室里如此逼真地模仿大脑功能。如果研究人员能用人的神经元重建这个模型,并提升到足以反映其他一些神经系统功能的水平,那么这个模型或可用于研究疾病、创伤和治疗如何影响大脑,从而避免人体临床试验的高费用和伦理问题。“In terms of mechanical similarity to the brain, it’s a pretty good mimic,” said James J. Hickman, a professor of nanoscience technology at the University of Central Florida, who was not involved in the research. “They’ve been able to repeat the highest level of function of neurons. It’s the best model I’ve seen.”“从与大脑的机械相似性来看,这是一个相当不错的模仿,”詹姆斯·J·希克曼(James J. Hickman)说。他是中佛罗里达大学(University of Central Florida)的纳米科学与技术教授,没有参与这项研究。“他们能够复制出最高水平的神经元功能。这是我看到过的最好的模型。”The research, led by David Kaplan, the chairman of the bioengineering department at Tufts University, and published Monday in the journal PNAS, is the latest example of biomedical engineering being used to make realistic models of organs such as the heart, lungs and liver.该研究由塔夫茨大学(Tufts University)生物工程系主任戴维·卡普兰(David Kaplan)主持,于周一发表在《美国科学院院刊》(PNAS)上。这是用生物医学工程手段制造器官——比如心脏、肺和肝脏——仿真模型的一个最新例子。Most studies of human brain development rely on animals or on brain slices taken after death; both are useful but have limits.研究人类大脑发育的工作大多依赖于动物实验,或人死亡后获取的大脑切片;两者都有用,但都具局限性。Brain models have been mostly two-dimensional or made with a three-dimensional gel, said Rosemarie Hunziker, program director of tissue engineering and biomaterial at the National Institute of Biomedical Imaging and Bioengineering, which funded Dr. Kaplan’s research.美国国家生物医学成像和生物工程研究所(National Institute of Biomedical Imaging and Bioengineering)的组织工程与生物材料项目主任罗斯玛丽·亨齐克(Rosemarie Hunziker)称,以前的大脑模型大多是二维的,或是用三维凝胶制作。该研究所资助了卡普兰的工作。None of those systems replicate the brain’s gray or white matter, or how neurons communicate, Dr. Hunziker said. “Even if you get cells to live in there, they don’t do much,” she said.亨齐克还表示,过去的系统都没有复制大脑的灰质或白质,也没有复制出神经元如何传导信号。“就算你能让细胞在模型中存活,它们基本上也做不成什么。”Dr. Kaplan’s team found that a spongy silk material coated with a positively charged polymer could culture rat neurons, a stand-in for gray matter. By itself, silk did not encourage neurons to produce axons, branches that transmit electrical pulses to other neurons.卡普兰的研究小组发现,一种涂有带正电聚合物的海绵状丝制材料可以培养大鼠神经元,用以替代灰质。丝制材料本身并不能让神经元产生轴突,也就是把电脉冲传递给其他神经元的突出部分。The researchers formed the silk material into a doughnut and added collagen gel to the center. Axons grew from the ring through the gel — the white matter substitute — and sent signals to neurons across the circle.这些研究人员将丝制材料做成一个圆圈,在其中心添加了胶原蛋白凝胶。轴突从圆圈的一边长出来,通过替代白质的凝胶,把信号发送给圆圈另一边的神经元。They got “these neurons talking to each other,” Dr. Hunziker said. “No one’s really shown that before.”亨齐克说,他们让“这些神经元互相交流。以前没人真正做到了这一点。”By adding nutrients and growth factors, scientists kept the brainlike tissue alive in an incubator for two months, at which point they experimented on it.通过添加营养物质和生长因子,科学家把这个类似脑的组织放在孵化器中,让其存活了两个月,然后开始在它上面做试验。Adding a neurotoxin essentially killed the neurons, as it would in a real brain. To simulate traumatic brain injury, they dropped weights from different heights.添加一种神经毒素基本上会把神经元杀死,就像在真正的大脑中那样。为了模拟脑外伤,他们从不同高度让重物掉到模型上。Dr. Kaplan said the brain-in-a-dish “didn’t go splat,” but reacted like “a kitchen sponge, and it would compress down and then partially spring back up.”卡普兰称,这个培养皿中的大脑“没有四处飞溅”,其反应更像是“厨房里的海绵,先是向下压缩,然后部分反弹起来。”He said measurements of glutamate, a neurotransmitter that surges in injury, showed that “the more severe the damage, the higher the spike” in glutamate.他说,大脑受伤会导致神经递质谷氨酸激增,而对模型中谷氨酸的测量显示,“受伤越重,激增的峰值越高。”Gordana Vunjak-Novakovic, a biomedical engineering professor at Columbia who has worked with Dr. Kaplan on other studies, described the model as a kind of “Lego approach,” a “modular structure” that can be expanded and made more complex.哥伦比亚大学生物医学工程系教授戈尔达娜·乌尼亚克-诺瓦科维奇(Gordana Vunjak-Novakovic)曾与卡普兰在其他研究上有过合作。她称这个模型的建造有点像“乐高用的方法”,是一种“模块结构”,可以扩展成更复杂的形态。“It is the first proof of principle that something like this can be achieved outside of the body,” she said.她说,“这是首次在原理上明,类似这样的东西可以在体外实现。”Dr. Hickman said future experiments would need to study other cells and regions in the brain. “They’ve set up an architecture so some clever person in the future could then do it,” he said. Dr. Kaplan said his team was working on sustaining the brainlike tissue for six months — and with human neurons created from stem cells. He plans to add a model of the brain’s vascular system, so researchers can study what happens when drugs cross the blood-brain barrier.希克曼表示,还需要有未来的实验来研究大脑的其他细胞和区域。他说,“他们已经建立了一个构架,将来会有聪明人用它来做工作。”卡普兰称,他的研究小组正在努力让这个类似脑的组织存活六个月,还要用上从干细胞生成的人类神经元。他打算加建一个大脑血管系统的模型,让研究人员得以观察当药物通过血脑屏障时会发生什么。Ultimately, he hopes the bioengineered model can be used “to study everything from drugs to disease to surgical effects to electrode implants,” he said. “I mean, the list is endless.”他的最终目标,是让生物工程模型能被用于“所有的研究,从药物,到疾病,到手术效果,再到植入电极,”他说。“我的意思是,可做的研究多得没完没了。” /201408/323607青岛无痛人流怀孕

青岛处女膜休复 Elon Musk might be facing some serious trouble in his quest to make Tesla Motors a global brand.埃隆·穆斯克一心想将特斯拉汽车公司(Tesla Motors)打造成一个全球知名品牌,但他现在可能真的碰上大麻烦了。The CEO of the electric car company is facing a trademark dispute in China, one of the foreign markets he was hoping to break into, according to Bloomberg News.据彭新闻社(Bloomberg News)报道,这家电动汽车公司的首席执行官在中国正面临商标纠纷,而中国是他非常希望打入的海外市场之一。Tesla began delivering Model S Sedans to China in April. That triggered a trademark suit from businessman Zhan Baosheng, who owns the trademark to the name in China.今年4月,特斯拉开始在中国市场投放Model S车型。这个举措促使中国商人占宝生提起了商标诉讼,他称自己在中国拥有特斯拉这个商标。Zhan wants Tesla to stop all marketing activities, and he is seeking around .9 million from the company. Zhan may face an uphill battle in winning his challenge though, as last year a Chinese regulator sided with Tesla regarding the trademark dispute.占宝生希望特斯拉公司取消所有营销活动,同时还要求这家公司赔偿约390万美元。不过占宝生要想赢下这场官司恐怕将面临艰苦的斗争,因为去年中国有位监管者明确表示,他在这场商标之争中持特斯拉公司。Bloomberg notes that other companies, such as Apple and Burberry, have faced international trademark disputes in the past.彭社指出,苹果公司(Apple)和柏利公司(Burberry)这些企业过去都曾深陷国际商标争端。The latest development casts a pall over Tesla’s ambition to expand in the world’s biggest auto market.最近这场争端无疑为特斯拉拓展中国这个全球最大的汽车市场的雄心壮志蒙上了一层阴影。 /201407/310982青岛即墨市做四维彩超多少钱城阳区妇幼保健院客服中心
