15510796_马丁·路德如何改变了啤酒_

Life 职场58WORLD VISION 2017.NO.23生活·美食文|郭北衡路德的啤酒杯总是满满的,他喜欢各地的啤酒,还吹嘘他妻子的酿造技能,并发起了一场有助于促进啤酒花使用的宗教改革运动。

这是否可以让他成为啤酒的守护神呢?马丁·路德如何改变了啤酒另外一种改革500年前的一天,一个不起眼的僧侣马丁·路德发起了反对天主教的抗议运动,从而改变了欧洲的历史。

马丁·路德的新教改革不仅改变了欧洲人的生活,崇拜,工作和创作艺术的方式,也改变了他们的饮食习俗。

其中就包括全世界,尤其是路德的德国同胞,都爱喝的东西:啤酒。

啤酒生产的变化是加入了一种野生多产植物的淡绿色圆锥型花:啤酒花。

今天,每个兜售啤酒的工厂都应该对路德和他的追随者表示感谢,因为他们把使用啤酒花作为反叛天主教的行为。

但是为什么新教徒决定拥抱这朵美丽的花呢,啤酒花与宗教反叛又有什么关系呢?新教徒热爱啤酒花这是一段如啤酒花一样稍带苦味的历史。

在16世纪,天主教垄断了啤酒的生产,因为它垄断了用于调味和保存啤酒的草本植物,比如甘草,艾叶,活血丹,蓍草,帚石楠,迷迭香,刺柏果,姜黄和肉桂。

但是教会没有对啤酒花征税。

当时啤酒花被认为是不受欢迎的杂草,它们在野外充满活力地四处生长着,这种植物的拉丁名字为Humulus lupulus意思是“爬狼”。

“天主教会不喜欢啤酒花”,《华尔街日报》的啤酒评论家,《酿酒师的故事:啤酒的世界史》一书的作者威廉·波斯特维克说,“其中一个原因是,德国12世纪的神秘主义者和著名的女修道院长希尔德加德今天,每个兜售啤酒的工厂都应该对路德和他的追随者表示感谢,因为他们把使用啤酒花作为反叛天主教的行为。

毒药简史及侦探小说中常用的毒药

毒药简史及侦探小说中常用的毒药

毒药简史及侦探小说中常用的毒药毒性等级划分(针对正常人)6级剧毒少于5mg/kg 少于7滴5级极毒5-50mg/kg 7滴至1勺4级很毒50-500mg/kg 1勺至1盎司3级有毒0.5-5g/kg 1盎司至1品脱或1磅2级轻毒5-15g/kg 1品脱至1夸脱1级微毒15kg以上1夸脱或2.2镑以上传统的毒药砷——元素的一种,不能再分解,在工业生产上应用广泛,因此比较容易取得,包括很多家用产品:墙纸、涂料、油漆等等。

人体中都有微量的砷存在,其在自然界最常见的103种元素中列第20位。

名称:砷、三氧化砷、氧化亚砷、白砷、灰砷、金属砷,砒霜。

毒性:5级性质:纯净的砷是灰色的晶体,具有金属性;自然状况下是白色的粉末状。

谋杀中,多以固体吞食物出现,其实作为汽状一样可以用作毒药使用。

但固体与气体中毒症状是有区别的。

症状:中毒者的皮肤会出现皮疹,甚至导致皮肤癌变。

最常见的则是胃剧痛,还有腹泻并带血,呕吐,体温下降,血压下降,头晕,痉挛,严重的是昏迷,血液循环停止导致死亡。

如果不是猝死,则中毒者会出现头疼、语言混乱或瘫痪,几天之内,砷会侵入肝脏和肾脏。

砷一般可以在患者的头发、指甲和尿液中找到,但如果是猝死者,则砷会在消化系统中被找到。

慢性中毒者手脚会极度疼痛,局部肿胀,脱发,心力衰竭等。

发作时间:症状最快会在1.5个小时内出现,急性中毒者会在24小时内死亡。

解毒:洗胃,注射“凝固剂”,肾透析手术注意:砷中毒的症状与胃炎有相似之处,慢性砷中毒会引发结肠炎。

使用推荐:三星半(满分五星),有效,容易取得,难以解救,但是使用的太多而导致太容易被发觉,没有个性,且中毒者发作的太慢。

氰化物——应用广泛,尤其是在工业上。

毒性:6级性质:除氢氰化物为液体,其它为白色固体,带有刺鼻的杏仁味道。

固体需要吞食,气态可由皮肤吸收。

症状:无论固体、液体或气体中毒,会导致人失去知觉、抽搐或死亡。

摄入量可致死的话,中毒者呼吸急促,头晕,面色发红,恶心,呕吐,心动过速,血压下降,抽搐,四小时内死亡,就算注射钠硝酸盐,十小时后仍会死亡。

红楼梦中的术语翻译,以杨戴译文为例参考资料

红楼梦A Dream of Red Mansions(杨,戴夫妇译本)Dream of the Red Chamber (美国人霍斯译本)个人认为后者比较恰当。

Mansion是大厦,楼房的意思;而chamber指女子闺房,更能体现红楼意境。

地名:大荒山 Great Waste Mountain无稽崖Baseless Cliff 即无根据的,无稽的悬崖青埂峰 Blue Ridge Peak 若从意思上看倒没什么问题,只是失去了“情根”的谐音,甚是可惜。

这也是翻译中最难顾全的方面之一。

仁清巷(甑士隐住处) the Lane of Humanity and Purity 即人道与纯净的小巷葫芦庙 Gourd Temple 这个易解,只是字面直译。

灵河岸(绛珠草所在) the bank of Sacred River 神圣之河,勉强。

三生石畔 beside the Stone of Three Incarnations 这里有些晦涩。

直接看就是“三次赋予人身的石头边”,好怪。

不过因为轮回是中国独特的说法,所以此处确实难以处理得当。

赤瑕宫 Palace of Red Jade 将“瑕”理解为“玉”?似乎有些联系。

太虚幻境 the Land of Illusion 因“太虚”原有“虚幻”的意思,因而此处只取“幻境”而略去“太虚”,个人认为极当。

智通寺 Temple of Perspicacity敕造宁国府 Ningguo Mansion Built at Imperial Command 奉皇旨建造的宁国府邸荣国府 Rong Mansion 这里只翻译了“荣”字,而之前宁国府却翻了“宁国”二字,不知什么原因。

荣禧堂 Hall of Glorious Felicity 荣耀,幸福之殿碧纱橱(黛玉初入荣国府住处) Green Gauze Lodge 绿色薄纱小屋。

其实意思上并无问题,只是总觉得一经翻译便少了那份优雅的美感。

Fake drugsPoison pillsCounterfeit drugs used to be a problem for poor countries. Now they threaten the rich world, tooSep 2nd 2010 | NEW YORKDRUG smugglers can expect harsh penalties nearly everywhere—if the drugs in question are heroin or cocaine. Those who smuggle counterfeit medicines, by contrast, have often faced lax enforcement and light punishment. Some governments deem drug-counterfeiting a trivial offence, little more than a common irritant. After all, whose spam filter does not groan with ads for suspiciously cheap “Viagra”?This could be changing, however. The pharmaceutical industry has persuaded several governments to stiffen regulations against fake drugs and to conduct more aggressive raids (see chart). Companies are also devising novel technologies to outfox the criminals. Even the Catholic church is joining the cause, issuing a stern statement in August that it is in “the best interest ofall concerned that smuggling of counterfeit drugs be fought against”.The pope’s concern is justified. Counterfeit drugs can kill. Many are shoddily made, containing the wrong dose of the active ingredient. Taking them instead of the real thing can turn a treatable disease into a fatal one. It can also foster drug resistance among germs. This has been a big problem for a long time in developing countries. Studies of anti-infective treatments in Africa and South-East Asia have found that perhaps 15-30% are fakes. The UN estimates that roughly halfof the anti-malarial drugs sold in Africa—worth some $438m a year—are counterfeits.Roger Bate of the American Enterprise Institute, a think-tank in Washington, DC, cautions that any such estimates should be treated with care. The countries with the most fakes may not be cracking down, so official figures will look rosy; in contrast, countries with a smaller counterfeittrade that are vigilant may end up with more seizures. The World Health Organisation agrees,and has recently taken its estimates off its website. Even so, Mr Bate says his field work has convinced him that counterfeits kill at least 100,000 people a year, mostly in the poor world.Now it appears that fakes are taking off in the rich world too. Yes, Viagra still tops the list of knock-offs seen by Pfizer, says John Clark, the American drug firm’s global head of security; but fake versions of at least 20 of its products (including Lipitor, a blockbuster cholesterol drug) have been detected in the legitimate supply chains of at least 44 countries. Mr Clark’s intelligence comes from Pfizer’s global network of informants, consumer tip-offs and in-store inspections. He sees worrying trends.Counterfeiters used to operate chiefly in developing countries, says Mr Clark, but now his firm sees fakes coming from such rich and well-regulated places as Canada and Britain. And the crooks are growing more technologically sophisticated: some can even counterfeit the holograms on packets that are meant to reassure customers that pills are genuine.A consumer study funded by Pfizer recently found that nearly a fifth of Europeans polled in 14 countries had obtained medicines through illicit channels. That, the firm reckons, makes for a grey market in the EU of over €10 billion ($12.8 billion). Terry Hisey of Deloitte, a consultancy, thinks the global market for fakes could be worth between $75 billion and $200 billion a year. Those staggering sums, he argues, help explain the emergence of a flurry of new technologies and companies hoping to help the drugs industry “secure its global supply chain”.In July Oracle, an American software giant, unveiled Pedigree, a programme that helps drugs firms “track and trace” pills all the way from the factory to your fingers. IBM has a rival offering, as well as one using radio-frequency identification (RfID) chips, which are embedded in packaging to detect tampering and allow precise tracking. 3M, a materials company, and Abbott Laboratories, an American medical firm, are also rolling out an RfID-based product. A division of Johnson & Johnson, a drugs giant, has developed web-based software to help customs officials quickly verify whether drugs are fake or real.Poor countries find it hard to take advantage of such technologies. Sophisticated radio tags and database software are not much use in places where street hawkers peddle fakes with impunity. Still, even in such difficult circumstances, a combination of political will and business ingenuity can make a difference.Bottom-up battleA Ghanaian start-up firm, mPedigree, has come up with a clever way to use mobile phones in this fight. Participating drugs companies emboss a special code onto packages, which customers find by scratching off a coating. By sending a free text with that code, they can find out instantly ifthe package is genuine or a fake.Bright Simons, the firm’s boss, argues that technologies like his can be a useful bottom-up complement to top-down enforcement. Having successfully completed initial trials, he says, mPedigree is ready to expand its service in the region. The government of Nigeria, where fakery is rife, recently declared its intention to adopt such a text-based validation system.Thomas Kubic of the Pharmaceutical Security Institute, an industry-funded outfit, gives warning that this war will be hard to win. After more than 30 years as an investigator, he is sure that crooks will eventually find a way around any defence.Even so, he thinks novel approaches such as mobile-based validation may “harden the target”, just as a burglar alarm makes your home somewhat trickier to rob. If the cost and complexity of faking drugs goes up, crooks may choose to fake Gucci handbags instead. This would still be theft, not to mention a crime against fashion. But it will not kill anyone.BusinessAbout The Economist online About The Economist Media directory Staff books Career opportunities Contact us Subscribe[+] Site feedbackCopyright © The Economist Newspaper Limited 2010.
