上饶市第二人民医院切眼袋手术多少钱上饶眼部祛皱方法 Money really does grow on trees – at least in Australia.树上真的可以长黄金——至少在澳大利亚是如此。Scientists have found gold in the leaves of eucalyptus trees.科学家们在桉树树叶里找到了黄金。The particles are much too small to be seen with the naked eye but have been detected using a type of x-ray that is especially good at picking up trace amounts of metals and minerals.这种树叶中含有的黄金粒子十分微小,不足以凭肉眼观察到,但是科学家们通过一种专门探查微量金属和矿物的X射线仪器发现了它们。However, gold hunters shouldn’t start felling gum trees in the hope of becoming rich.但是,猎金者们大概不能通过伐木来采金致富。Study leader Mel Lintern told the Brisbane Times: ‘If you had 500 eucalyptus trees growing over a gold deposit, they would only have enough gold in there to make a wedding ring.’科研小组的领队梅尔·林特恩对记者说,“如果让500棵桉树生长在一个金矿上,这些树中收集到的金子大概足够打一枚金戒指。”The real value of the study is that nature’s own version of gold leaf could provide mine companies with an inexpensive and environmentally friendly indicator of where to drill test sites.这一研究的真正价值在于,这种自然界而非小说里出现的金叶子可以充当金属探测器,这种探测方式既环保又方便,可以告诉探勘者在哪里能开采到金子。The study by the Commonwealth Scientific and Industrial Research Organisation in Western Australia showed levels of the precious metal were highest in trees growing directly over gold seams, one of which was 115 feet down.这项研究成果是由澳大利亚西部的联邦科学与工业研究组织成员做出的,该研究组织发现,直接生长在金矿层上的桉树叶中的黄金含量是最高的,其中一个金矿在地下115英尺(约35米)深。The researchers believe the gold was taken up by the trees’ extensive roots from while scouring for water during times of drought.研究者们相信,树叶中含有的金子是树根在干旱时期、四处蔓生以寻找水源时被吸取到树中的。It was then transported through the tree to the leaves, where concentrations are higher than in the twigs, trunk or surface soil.被树根吸取的金子被输送到枝干和叶子中,金子在叶子中的密集度比在树枝、树干和表层土壤中都要高。The researchers said: ‘Gold is probably toxic to plants and is moved to extremities, such as leaves in order to reduce deleterious biochemical reactions.’研究者说,“对于植物来说,黄金是有毒的,因此黄金被传送至树叶等植物的末端,这样可以减少破坏性的生化反应。”Writing in the journal Nature Communications, they said it was the first time that gold had been found naturally incorporated into a living thing.这一研究成果已经在《自然通讯》期刊上发表,科学家称,这是人们首次在植物体内发现自然贮藏的黄金。 /201310/262668上饶广丰区大腿抽脂价格多少

上饶信州区光子脱毛多少钱The private jet company owned by Warren Buffett’s Berkshire Hathaway is moving into China, where it sees huge growth potential.沃伦#8226;巴菲特(Warren Buffett)持有的伯克希尔哈撒韦公司(Berkshire Hathaway)旗下私人飞机业务NetJets正进军中国,在这里看到了巨大的增长潜力。NetJets has secured a licence to fly from the Chinese civil aviation authority, allowing it to set up in a country where there is little private jet activity.NetJets已从中国民航局获得飞行牌照,将在中国展开业务。中国的私人飞机业务几乎还是空白。“With the wealth distribution in China right now, where you have over a million millionaires and quite some number of ultra-high net worth individuals growing each year in leaps and bounds, we see private flying becoming more dominant,” said Robert Molsbergen, chief operating officer of Executive Jet Management, the brand under which Netjets will operate in China.Netjets的在华业务品牌为“Executive Jet Management”。在华公司首席运营官罗伯特#8226;莫尔斯伯根(Robert Molsbergen)表示:“根据目前中国的财富分配状况,中国拥有100万名百万富翁,还有很多超高净值个人,他们的数量每年都在飞速增加,我们认为私人飞机业务将变得更为重要。”Over time, Mr Molsbergen said he believed China could provide more business than NetJets’ main market in the US.莫尔斯伯根表示,他认为,假以时日,中国的业务规模可能会超过该公司的主要市场美国。China’s vast distances and potential demand for corporate aviation could make it a lucrative market, but the main barrier to setting up in the country has been government regulation.中国地域辽阔,企业航空业务潜在需求巨大,可能成为一个利润丰厚的市场,但在中国开展业务的主要障碍是政府监管。NetJets has been trying to win its operating certificate for two years, and to make its venture work it has partnered with two Chinese companies that together own a majority stake in the business – private equity firm Hony Capital and investment fund Fung Investments.NetJets用了两年时间获得运营牌照,并让该公司与中国两家公司联手创建的合资公司开始运转。这两家中国公司是私募机构弘毅投资(Hony Capital)和投资基金冯氏投资(Fung Investments),它们持有该合资公司的多数股权。“If they’ve got a licence, that’s a start,” said Gerald Khoo, analyst at Liberum. “But there are all sorts of operational and regulatory restrictions. There is an awful lot of regulation over who can fly where – the Chinese military doesn’t like the idea of people flying wherever they like.”“如果他们获得牌照,只是个开始,”Liberum分析师杰拉德#8226;邱(Gerald Khoo)说。“中国有着各种各样的运营和监管限制。对于谁可以飞到哪里,有着大量规定,中国军方不喜欢看到人们随意飞行。”China also lacks a developed infrastructure network for private aviation, although Mr Molsbergen said there were 200 airports private jets could fly to.中国还缺乏完善的私人航空基础设施网络,不过,莫尔斯伯根表示,目前私人飞机可以在200个机场起降。NetJets has begun operations in China by basing two aircraft at Zhuhai Jinwan airport in the wealthy southern province of Guangdong, and will initially offer charter flying and services such as maintenance, crewing and storage of jets.NetJets目前在富有的中国南方广东省的珠海金湾机场拥有两架飞机,最初将推出包机和维修、机组人员配备以及飞机存储等务。Ohio-based NetJets was set up 50 years ago and its biggest market is in the USIn Berkshire Hathaway’s annual report, NetJets’ 2013 revenues were recorded as increasing 7.5 per cent to 8m. Earnings were up 7 per cent to an undisclosed figure.NetJets总部位于俄亥俄州,创建于50年前,最大市场在美国。在伯克希尔哈撒韦公司的年度报告中,NetJets 2013年的收入增长7.5%,至2.88亿美元。收益增长7%,但具体数字未披露。 /201409/331605 上饶妇保医院做抽脂手术多少钱横峰县脸部抽脂价格
