惠州市中大惠亚医院男科专家惠阳区包皮手术怎么样Back at the explosives lab, examiners use a high-tech instrument called a Raman spectrometer, a device that determines if a package contains explosive material. With the Raman, what we are doing is that we are using, a, a light source to go into the container and actually get a spectrum off of the substance inside the container. There we're actually able to examine a suspected explosive substance without even having to open the container. And that's great for in the laboratory when you don't wanna put yourself at risk any further than you have to. At the federal building in Oklahoma City, no secondary devices are found. But while the nation is horrified at the carnage. The Explosives is quickly searching the wreckage for evidence to be used in a test called: residue analysis. This helps the FBI determine what chemicals fuel the blast. First thing that happens is... is that the part of our unit that does the residue analysis takes the evidence, extracts anything that they can find from there that would help them identify the explosives. Within hours, residue analysis pinpoints a key piece of evidence. There we were fortunate that we actually did find a piece of debris that had some of the ammonium nitrate prills that were still embedded in it. And from those prills, we were able to conclude that it was an ammonium nitrate based explosive. From these findings the FBI concludes that a fertilizer bomb was used in the most deadly terrorist attack on US soil. Now the search for a suspect begins. The challenge for the Explosives is to determine how the massive bomb was brought to the scene. If it's a very large bombing, it's probably gonna be a vehicle. So we wanna try to identify that vehicle as quickly as we can. And here you can see some pieces that we did in a test with a vehicle. And you can just see the extent to which these are mangled by the explosion. Within a short time, investigators located the axle of a truck that was blown nearly 600 feet away from the federal building. From that axle, the bomb technicians who were at the scene were able to very quickly identify it as having come from the bomb vehicle, and then they were able to give that information to other investigators who tracked it back to the rental facility. In less than a day, suspected bomber Timothy McVeigh is taken into custody. But examiners investigating the murder of the New Jersey ad executive are not so lucky. With no sign of a suspect, they focus their attention on the bomb itself and begin a process known as device analysis. When we're doing an analysis of a device, what we were trying to do is simply to identify the components found there, and trying to see if we can figure out how they were put together, how they worked, or in some cases, how they didn't work?Raman spectrometer: a device to analyze the intensity of Raman scattering of monochromatic light (单色光) as a function of frequency of the scattered light; the information obtained is useful for determining molecular structure12/93048博罗县中医医院看男科怎么样   Russian President Dmitri Medvedev will be in the ed States in the next few days. His visit will focus on economic and trade matters.The high point of President Medvedev's stay in the ed States will be his visit to Silicon Valley - an area in northern California known for its high-tech companies, venture capitalists and forward-looking entrepreneurs.  Experts, such as Robert Legvold from Columbia University, say Mr. Medvedev is trying to generate interest in his plan to create a Russian Silicon Valley in the suburbs of Moscow known as the Skolkova Innovation Initiative."That area of Skolkova, where the Skolkova School of Business and Management is located, has a fair amount of acreage," he said. "So when Medvedev committed himself to the idea of creating a Silicon Valley, and there were a number of parts, different cities in Russia that vied for its location, it was decided to put it in this park. I think the notion is that there will be some link between the businesses and research centers that are created and the school."David Kramer, former senior State Department official in the George W. Bush administration, says the Russian president will be in northern California to try and form business partnerships and to learn how Silicon Valley got started."He's looking for investment. He's looking for expertise and know-how," he said. "He's looking to form consortiums and alliances with the private sector, with the universities." "And the question is how much interest there really will be and how much money there might be, at least from the outside. There's money in Russia that can be provided to fund some of this, but how much money from the West is there in supporting this kind of initiative? Those are questions that don't have answers yet," he added.Skolkova initiativeAnalysts say President Medvedev's idea of creating a Russian Silicon Valley is tied to his broader plan to modernize the country's economy."There is a realization at the end of the day that despite all the profits that Russia got from its sale of oil and gas over the last 10 years, that unless it modernizes its economy and reforms it, it will be a declining power," said John Parker [expressing his own, personal views] with the National Defense University. "So there is what seems to be a growing body of opinion in Russia among leadership circles that Russia has to start investing in its own technology sector."For that to work, Parker says the Skolkova initiative must be copied throughout Russia. "The danger is that it would just be a very confined experiment," he said. "You really need system-wide Skolkovas - Silicon Valley - otherwise it ends up just like under Catherine the Great when they imported a lot of German tradesmen and planted them in various settlements - but they were fairly self-contained. To really do the trick, Skolkova can't be self-contained. Its rules have to apply to all of Russian society, to all of Russia's economy."After visiting Silicon Valley, President Medvedev comes to Washington for a brief summit with President Barack Obama. Bilateral relationsExperts such as David Kramer say relations between the two countries are good. "The Obama administration touts the U.S.-Russian relationship as one of its major foreign policy successes," he said. "I wonder whether that says more about the rest of its foreign policy than about the U.S.-Russian relationship." Experts say the two sides also will discuss a host of other issues, including arms control after the recent signing of the New START Treaty, what to do about Iran following tougher ed Nations sanctions, as well as trade and economic questions."But having said that, relations are certainly better than they were at the end of 2008, when there were significant tensions between Moscow and Washington in the aftermath of the Russia-Georgia war. And so the tone and environment are much better than they were," he continued. 俄罗斯总统梅德韦杰夫即将来美国访问,这次访问重点将集中在经济和贸易方面。 梅德韦杰夫在美国逗留的重点将是访问硅谷,这个位于北加州的地区以高科技公司、风险投资家和前瞻性企业闻名。 专家说,梅德韦杰夫为他计划在莫斯科郊外建立俄罗斯硅谷而努力激发人们的兴趣。俄罗斯计划在斯科尔科沃开发科技创新园区。 哥伦比亚大学教授罗伯特.莱格沃尔德说:“ 斯科尔科沃管理学院所在地区就是这个科技创新园区选定的地址,那里有比较宽阔的土地。当梅德韦杰夫致力于兴建这个硅谷的时候,俄罗斯有很多地方的不同城市争相提出承办这个科技创新园区,最后确定在斯科尔科沃。我认为这意味着在这里创立这个园区是要和这个管理学院形成一种联络。” 小布什政府时期在国务院任职的高级官员戴维.克拉默说,梅德韦杰夫将到硅谷努力建立生意伙伴关系,学习硅谷创业的经验。 他说:“他是来寻找投资的。他来搜寻专业技术和高科技。他希望成立财团,和私营企业和大学形成联盟。” “问题是从外界能真正吸引多少兴趣,能得到多少可能的资金。俄罗斯可以为此提供资金,但是从西方国家可以得到多少对这一园区的持呢?这些问题还都没有。” 分析人士说,梅德韦杰夫要创立俄罗斯硅谷的想法和他更广泛的实现俄罗斯经济现代化的计划是密不可分的。 约翰.帕克是国防大学的教授,他表达了他个人的看法。他说:“ 俄罗斯最终认识到,尽管他们过去10年一直通过出售石油和天然气获得了大量收益,它仍将是一个走下坡路的大国。除非它实现经济现代化,将经济进行改革。俄罗斯领导层逐渐认识到,必须开始对本国技术领域投资了。” 帕克说,俄罗斯要做到这一点,斯科尔科沃科技园区必须成为俄罗斯各地的榜样。他说:“ 危险在于这仍是一个非常受限制的实验。俄罗斯真正需要的是体制的改革,也就是体制范围的硅谷化。否则这些努力不过是当年俄国女皇叶卡捷琳娜改革的翻版。她吸收了大批德国商人把他们安置在各地,但这些人基本上是自成一体的。俄罗斯的条例必须适用于整个国家和社会,适用于俄罗斯的经济。”  访问硅谷之后,梅德韦杰夫总统将前往华盛顿与奥巴马总统举行简短的峰会。包括克雷默在内的一些专家说,美俄两国之间的关系良好。克雷莫说:“奥巴马行政当局把美俄关系大力宣扬为它外交政策的重大成功之一。我想这也许是对奥巴马政府外交政策的其它部分的评价,而不是评价美俄关系。” “不过,尽管如此,两国之间现在的关系肯定比2008年年底的时候要好。那个时候,俄罗斯打完了和格鲁吉亚的战争,莫斯科和华盛顿的关系相当紧张。现在两国对话的语调和气氛比过去改善了很多。” 专家说,美国和俄罗斯将讨论很多其它方面的问题,包括最近签署了削减战略武器新条约之后的军备控制、联合国对伊朗实施更严厉制裁之后如何应对伊朗、以及其它贸易和经济问题。201006/106700The U.S. Senate has approved a bill aimed at helping the country's small businesses, giving President Barack Obama a political victory in his effort to revive the country's economy.The Senate passed the bill Thursday with the help of two key votes from opposition Republicans. It now heads to the U.S. House of Representatives, which is expected to pass the bill and send it to the president to become law.President Obama says U.S. exports had a bigger-than-expected increase during the past year, which he says will help fight unemployment.奥巴马总统说,过去一年来美国的出口增长超过预期,这会帮助降低美国的失业率。"Obviously working off a low baseline, given the crisis last year, exports are expected to be up, but we are very pleased to see that they are up 18 percent, to where they were a year ago," Mr. Obama said. "And manufacturing exports are up 20 percent, and that is helping put a lot of our people back to work."奥巴马说:“我们的起点显然很低,尤其是在去年发生经济危机的情况下,出口预期会增加。但出口一下子增长了18%,并恢复到一年前的水平,这让我们非常高兴。特别是制造业的出口增长了20%,这会让很多美国民众重新就业。”The U.S. unemployment rate remains mired at 9.6 percent, which has depressed Mr. Obama's public approval ratings and hampered candidates from his Democratic Party.美国失业率继续维持在9.6%的水平,这影响到奥巴马总统的公众持率,并影响到民主党籍候选人的选情。The president says one way out of the recession is to sell more American goods and services in other countries.奥巴马总统说,摆脱经济衰退的一个途经就是向海外出口更多的美国产品和务。"The more American companies export, the more they produce," the president said. "And the more they produce, the more people they hire. And that means more jobs - good jobs that often pay as much as 15 percent more than average."他说:“美国公司出口越多,生产就会越多。生产越多,新聘雇员就会越多。这就意味着会创造更多的就业,而且是薪酬不错的工作,经常比平均工薪高出15%。”201009/113979惠州女性皮肤科医院诊所

惠州友好男科医院包皮手术多少钱Chinese factory fears Normally shut down this time of year, factories in China open their doors to stranded workers. CNN's Eunice Yoon reportsBlizzards, icy weather and freezing temperatures, that pretty much sums up what China's had to deal with for more than a week now. It's left millions stranded and sent a big chill right through the economy. Asia Business Editor Eunice Yoon has more details on that. Eunice, things do look like they are improving a bit at the moment, but you know, really it has been an atrocious situation for so many millions of people.It really has. I mean for more than a week now, migrant workers have been huddled at train stations with little hope of catching a ride home. But it's not just the workers who have been left out in the cold.The start of the Lunar New Year, generally a slow time for business in China. Most factories shut down as millions of workers head home for the holiday. But this year with China's worst winter in half a century, halting trains and traffic, manufacturers like Goldlok are getting y for some workers to return earlier than expected. "Some of them, you know, twenty percent almost start coming back to the factory because there's a lot of traffic jam on the station. And that's why we need to reopen the factory for them."Heavy snowfall paralyzed sections of the country's rail system, leaving millions of people---many of them factory workers---stranded. Some services are resuming, still with the backlog of travelers, the government urged migrant workers to cash in their tickets and spend their only holiday for the year back at their factory dormitories."We need to have some people to especially to care their emotional needs. They leaving their hometown, you know, and work for a whole year and what their hope is going back home to visit their family, so if they can not go back because of the traffic, they would be very very upset."It's a painful move for manufacturers, too. They have the added expense of reopening factories early at a time when the snowstorms have caused power shortages and are threatening to delay shipments. Analysts say it adds to growing concerns and costs for exporters."China's export sector has its own problem. The production cost went up quite a bit. And the new labor law certainly has all kinds of implications to the cost and exchange rate continue to appreciate."Not a very auspicious start to 2008.Some economists said that the severe weather is likely to affect exports for January and possibly into February. And as far as the longer term forecast. Eunice, do you think that the effects of the snowstorm are going to be felt down the road? "Well, not for exports, but definitely for food prices. We're aly seeing a spike in a lot of the prices for staple vegetables, such as cabbages, some of them as high as 50% up. But going down the road a lot of economists say that the summer crops have likely been severely damaged, that's going to escalate inflation in China at a time when they really don't need er, higher prices up, but one thing that I thought was pretty interesting is that even further down the road for the autumn crops, some economists that I have been talking to say that those crops might benefit from the snowfall because there is more melted water or melted snow which turns, of course, into water, and right now there is a water shortage in China. So that's, of course, another possibility, er, positive possibility down the road." Notes: blizzard: A violent snowstorm with winds blowing at a minimum speed of 35 miles (56 kilometers) per hour and visibility of less than one-quarter mile (400 meters) for three hours03/63455惠城区男科电话 On a previous show we discussed how, every 200,000 years or so, the north and south poles switch places. Not that the places themselves move—rather, the entire magnetic field of the earth flips around, resulting in the pole we now call “north” being on the southern tip of the planet, and vice versa. Why does this happen? Although it seems pretty solid, the outer core of our planet is in a molten state. That means it’s partway between what most folks would call liquid and solid. Much of this molten interior is iron and nickel. These are elements that conduct electricity very well. It’s the fluid metals that move about inside earth that generate a magnetic field around our entire planet. Although from close up these metals are bubbling like hot soup, you could also say that in general their motions follow a pretty steady pattern. That’s why the magnetic field on earth is pretty stable.【生词注释】switch v.转换magnetic field 磁场flip vt.快速翻动tip n. 顶端solid adj. 固体的, 坚固的molten adj. 熔化的partway adv. 到某种程度interior n. 内部close up n. 靠近bubble v. 冒泡, 沸腾在先前的节目中我们讨论了每隔20万年,地球的南北极都要互换位置,不仅是地点的移动,而是整个地球的磁场快速翻转,导致我们现在称作“北极”的地方原来在地球的南端,正好与原来磁场相反。这种现象为什么会发生呢?尽管地球的外壳看起来很牢固,实际上它处于融化的状态中,那意味着地壳处于液体和固体间的中间形态。这种溶化物质的大部分组成部分是铁和镍。这些都是极易导电的物质。它们也是在地球内部流动的液体金属,从而形成了整个地球的磁场。尽管从近处看,这些金属就像热汤那样冒泡,你也可以说从整体上来看,他们的运动遵循着一种十分稳定的模式。那也是地球磁场十分稳定的原因。 201111/160149惠州那家男科好

惠城区人民男科医院治疗生殖感染价格Music TortureGroups call on U.S. to stop using music as torture It is torture. I have no doubt about it in my mind. It is torture.Donald Vance was a detainee in the US military's Camp Cropper in Iraq, held for months after he reported evidence of corruption. Vance says he was forced to listen to ease but in music for months on end and that nearly drove him to suicide. Detainees, some US officials and human rights groups say US forces have systematically used loud music against hundreds of detainees in Afghanistan, Guantonamo Bay and Iraq.You can hear them screaming. You can hear them crying out aloud. They are usually calling out for their mothers or calling out for God to help them. And, yeah, you can, you can hear someone calling insane.But they keep loud all that long by blasting loud music. We're trying to get them stop it.In a campaign being launched on International Human Rights Day, Reprieve, a legal group, representing some Guantonamo detainees, along with musicians, are protesting the use of music during interrogations. Not all of the music can question it. It's hard rock either.~~Put down the duckie Put down the duckie Yeah, you gotta leave the duck alone...~~~Christopher Cerf, a songwriter for Sesame Street was horrified to learn that songs he penned for children's TV shows were used in interrogations.Humorously, I made the point that I was going to sacrifice those, those writings for my country. But this is not the way I want my songs to use.Reprieve Zero DB for Zero decibel campaign calls for the enforcement of UN convention against torture and the courageous musicians to hold a minute of silence at concerts. One interrogator at Guantonamo bragged that he needed only four days to break someone, using music and lights. Ruhal Ahmed, a British citizen who was captured in Afghanistan told Reprieve he was much worst when the music started.That makes you feel like you are going mad. After the wall, you don't hear the lyrics. All you heard is heavy, heavy band gink.A Guantonamo Bay spokeswoman would give details of 'when' and 'how' music has been used at the prison and would also not respond when I asked whether music might be used again in the future.Tracy Brown, the Associated Press.200812/59478 Microsoft and Intel微软和英特尔Wintel swings微软和英特尔各觅新欢The marriage that dominated personal computing becomes more open强强联姻主导个人电脑市场之势日趋明朗Sep 17th 2011 | from the print editionTOGETHER Microsoft, the maker of the Windows operating system, and Intel, the world’s biggest maker of semiconductors, used to rule the world of personal computing. Now that new computers are as likely to sit in people’s hands as on their desks or laps, life for the Wintel couple is less comfy. On September 13th, at their annual conferences for software developers, both claimed to have found new zest—not least from dallying with other partners.微软(Windows操作系统的开发者)和英特尔(世界最大的半导体制造商),曾联手统治了个人电脑市场。然时代变迁,如今的电脑已不再局限于放在桌上、膝上,还能持于手上。于是乎,微软和英特尔这两口子也开始心猿意马。就在9月13号,一年一度的软件开发大会上,两口子都宣布已有了新的对象——不仅仅只是和别人眉目传情、暗送秋波了。Gartner, a research and consulting firm, expects that this year only 3.8% more laptop and desktop PCs will be shipped than in 2010. That is partly because people have tightened their belts, but also because they are snapping up tablets and smartphones. Both Microsoft and Intel have struggled to adjust. The phone version of Windows has had good reviews but was installed in only 1.6% of smartphones sold in the second quarter; Google’s mobile operating system, Android, scooped 43%. Windows’ share of tablets is minuscule. And in markets where battery life is prized, economical chips designed by ARM, a British company, have made the running. Intel has made virtually no impression in tablets and none at all in smartphones.研究与顾问咨询公司高德纳预计,今年的笔记本和台式个人电脑的发货量较2010年顶多增长3.8%。这里面部分是因为现在的人都在拉紧裤腰带生活,但也有部分原因是他们都去抢购平板电脑和智能手机了。对此,微软和英特尔都是心急如焚,急于转变。Windows手机综合测评不错,但第二季度只有售出的智能手机只有1.6%是安装其操作系统。而谷歌的安卓操作系统却抱走了43%的市场份额。在平板电脑市场Windows所占份额更可谓是芝麻粒豆。再者,在如今这个极其重视电池续航能力的市场情况下,节能型芯片可谓是前景广阔,而英国ARM公司在这方面已是先拔头筹。可怜的英特尔对平板电脑市场几无影响,对智能手机更是无比汗颜。Both firms boasted this week of liaisons with others. Intel and Google said that future versions of Android would be tuned for Atom, Intel’s family of low-power processors. Phones with Intel inside should be on sale in the first half of next year. Microsoft showed off the next version of its operating system, code-named Windows 8, using ARM chips. It wants to reassure the army of developers who write programs to run in Windows that these will be just as reliable as Intel’s.本周,微软和英特尔都在高调宣传他们的新感情生活。英特尔和谷歌结了姻,英特尔家族的节能处理器凌动未来将会和安卓系统合体,预计将会于明年上半年诞生。另一方面,微软则看上了ARM,并对他们的后代表示出极高的自信,冠以Windows 8的美名。微软此举也就是想消除那些开发Windows系统软件的人们的疑虑,表明此产物会如与因特尔所产的那样稳定可靠。201110/155825惠州中医院包皮手术多少钱惠城区阳痿早泄价格
