福州省妇幼做试管多少钱福建妇幼保健院B超监测卵泡Self-treatments using baking soda, ash and hydrogen peroxide provided online with no dental experience, can strip tooth enamel and cause lasting damage to the gums, experts cautioned.   专家提醒,网上流传的用苏打粉、灰末和过氧化氢进行牙齿美白的方法,若没有牙医的指导,会损伤牙釉质,给牙齿带来永久的伤害。  The techniques are becoming an increasingly popular alternative to expensive professional treatment, especially among teenage girls.  目前这些美白方法广受欢迎,尤其是受到少女们的追捧,并逐渐取代了昂贵的专业美白治疗。 But dentists said some of the methods can erode the enamel covering of the teeth, making them appear darker rather than whiter.  但牙医提醒说,有些方法可能会损伤覆盖在牙齿上的牙釉质,反而让牙齿显得更黑。  Up to 100,000 people undergo some type of teeth whitening treatment each year, ten times more than did so five years ago.  近年来,每年进行牙齿美白的人数已经达到10万人,是五年前的十倍。  But for many people the process is prohibitively expensive, costing up to £1,300($2,096) for laser treatment and as much as £700($1,128) for professional bleaching.  但是对于很多人来说,进行专业牙齿美白的费用太过高昂。激光美白的费用是1300英镑(约2096美元),专业牙齿漂白至少需要700英镑(约1128美元)。 Professor Andrew Eder, clinical director of the London Tooth Whitening Centre, said using baking soda repeatedly would strip the teeth of enamel, leaving them browner and more sensitive, while salt would scratch the enamel and any use of acid was especially damaging.  伦敦牙齿美白中心临床主任安德鲁 埃德尔教授表示,反复使用小苏打会损害牙釉质,牙齿会变得越发暗沉、敏感;用盐可能会刮伤牙釉质;而使用任何盐酸美白牙齿带来的伤害则更大。 /201011/117713南平检查精子活性公立医院 THE BRIGHT SIDE Aquarians are lively, inventive and original. Anything goes with Aquarius, and being an individual does not worry this sign: in fact, Aquarius is always out of step with the rest of the world and revels in anything that is 'different'. Humanitarian The Aquarian personality is one of the most impersonal and detached, yet Aquarius has a deep care and concern for humanity. A progressive reformer, Aquarius is also full of humanitarian ideals, but these can be somewhat vague, giving Aquarians a reputation for keeping their heads in the clouds. EccentricAquarius is also one of the most happily eccentric of the signs. Although it can be extremely difficult to get close to an Aquarian, this is a Fixed sign and so is loyal and faithful. Ask an Aquarian for help and you will immediately get it, for this sign is a very soft touch and would willingly give some people the shirt off its back if necessary. UnpredictableTHE DARKER SIDE The Aquarian personality can be chaotic and unpredictable, stubborn and rebellious, cranky and perverse. It is a sign which can be totally dedicated to being unconventional, whilst remaining stuck in a rigid, unrecognized pattern. It is also a sign which can become detached to the point of coldness, making it very difficult for ordinary mortals to relate to them. Aquarians do not care what the world thinks, however, so that social conventions are sometimes thrown out of the window in favour of anarchy. The isolation this can sometimes bring can cone as a surprise to them as they find it difficult to see how they might have behaved unreasonably. /200911/89639Sometimes it's best not to keep your cool. In fact, hotheaded stock investors make better decisions, a study in the Academy of Management Journal showed. Adding emotions to the decision-making process can enhance creativity, engagement and decision efficiency, the researchers wrote in the study.The greater the average intensity of an individual's feelings, the higher their investment returns, they found. The study monitored 101 stock investors in a simulated trading exercise spanning four weeks. "Contrary to the popular belief that the cooler head prevails, people with hot heads--those who experienced their feelings with greater intensity during decision-making--achieved higher decision-making performance," they wrote.But showing emotion on the trading floor is still a controversial subject. "I'm no friend of emotion in trading," said Peter Kenny, managing director at Knight Equity Markets in Jersey City, New Jersey, who has been trading stocks for more than 25 years. "It's much more important to be disciplined." /200812/59014福州腹腔镜手术哪里比较好

福州省妇幼医院做试管怎么样Is it really? Well, according to Dr. Mao over at Yahoo Health, this is quite true. He also presents some practical things that we could all do to help the environment and be healthier at the same time. Seeing as we have just recently celebrated Earth Day, this topic is quite appropriate, don’t you think? Let’s take a look at some of Dr. Mao’s suggestions.Less Plastic, More HealthLightweight, durable and versatile, plastic is everywhere in our modern world; this is bad news for the environment and our health.He lists down a lot of things at home which are made of plastic. This prompted me to look through some of my things and he is right! Heck, even this laptop I am using has a lot of plastic parts. So what’s bad about plastic?According to Dr. Mao, “many plastics release vinyl chloride and other harmful estrogen-like substances that can lead to cancer, birth defects, hormonal imbalance, and lung and liver disease.”He might be right or he might be overstating things a bit but it wouldn’t hurt to use less plastic.Some practical suggestions? Instead of using plastic containers as the default, why not use glass ones instead? I also like the wooden and ceramic variations as well.Let’s look at a few more things next time. 这是真的吗? 好,通过毛士在雅虎健康网上说的,这的确是真的,他也举了几个我们能够做的实际事情保护环境,同时这些事情更有益于健康.鉴于我们刚刚庆祝的地球日 ,这个话题是比较合适的,你不觉得吗?让我们看看毛士的一些建议吧.少一点塑料,多一点健康。轻便,耐用以及多功能的塑料在现代社会随处可见,这对我们的环境和健康非常不利。他列举了一些在家使用的塑料制品。这促使我审视一些我的东西,我发现他说的对!令我来气的是我的笔记本电脑也用了许多的塑料零件。那么,关于塑料有什么不好呢?毛士说许多的塑料能释放氯乙烯和其他的有害的的雌性激素,人吃了能够致癌,导致出生缺陷,激素不平衡以及肺病和肝。他说的也许对或者是夸张了一点,但这并不对少用塑料的人造成伤害。还有其他的一些实际的建议吗?,既然不用塑料容器是默认,为什么不用玻璃代替呢?我同样喜欢木制的和陶瓷替代品。 /200806/42591福州卵泡监测公立医院 各位有没有想过,为什么在英语写作的时候,第一人称单数的代词I不管出现在句中什么位置都一定要大写呢?为什么you,we,they,he,she之类的人称代词不用大写呢?北京大学英语系教授辜正坤先生在央视《讲坛》“当茶遇到咖啡”系列节目“中西语言文字与文化比较”一讲中对上面这个问题有这样的解读:“我们人类的文化,包括中国的文化和西方的文化,有时候在口语当中容易表现出来,最简单一个字就可以把问题说清楚。举个例子来说,在英语当中,以代词来说吧,你(you),我们(we),他们(they),他(he),她(she),这些代词都是不大写的,但是只有一个字要大写,谁呀,I,我就要大写。那么反过来说,在中国他就刚好相反,同样的是称呼“我”,那么中国人是怎么称呼呢?他就不会去大写了,当然没有那个拼写的大写,用别的方式来表述,会说“在下”、“鄙人”,就是皇帝也会称自己“寡人”或者“孤”,都是尽量地尊重别人,克制自己的这种心态。这跟西方文化当中的“我”一下子就区别开了。一个代词的使用就可以看得出来这两种文化是分道扬镳的,在很多方面极性是相反的。”第一人称单数的代词I大写这个问题在语言学中是有共识的。《巴恩哈特语源学辞典》(The Barnhart Dictionary of Etymology ,W H. W. Wilson,1988)中就有这样的解释:"The pronoun 'I' developed from the unstressed form of Old English (about 725) ic singular pronoun of the first person (nominative case). Modern and Middle English I developed from earlier i in the stressed position. I came to be written with a capital letter thereby making it a distinct word and avoiding mising handwritten manuscripts. In the northern and midland dialects of England the capitalized form I appeared about 1250."也就是说,在古英语中“我”最初是用ic两个字母来表示,逐渐演变成为单个字母i。一旦成为单个字母i的时候就出现了一个问题,i这个小写的词在手写体中很容易与前后的词混淆,所以大约在1250年起英格兰中部和北部的方言中就开始使用大写的I。《莫里斯字词源词典》(Morris Dictionary of Word and Phrase Origins)也指出,把I(我)大写与ego(自我意识)无关,只是为了避免混淆和错误(the reason for the capital I is simply to avoid confusion and error)。此外,也有语言学者认为,I作为人称代词与you,they,he,she还是有区别的,因为这是书写者的自称,比如John Wilson是作者的话,如果写自己的名字当然要大写,所以当用I来代表John Wilson时也要大写。所以,英语中第一人称单数I大写并不是因为西方人个人至上、自我中心的思维逻辑。说到逻辑,辜正坤教授上面的那段话也有不严谨之处。英语中的I大写只是英语的语法,并不代表其他欧洲语言的第一人称单数也一定大写,比如法语的je(我)在句中出现时就不能大写。辜教授是如何从一个简单的英语单词推广到所有西方语言进而得出西方文化与中国文化“分道扬镳”的呢?当然,我质疑I大写的文化含义,只是认为这个例子举得不够恰当,并非否认英语和汉语词汇区别的确可以显示东西文化差别。美国夏威夷大学汉学家、哲学家安乐哲(Roger T.Ames)教授举过这样的例子:比如用英文说:“Everybody please stand up.”我们要用everybody(每一个身体)、everyone(每一个人)来讲,换作中文来说就是“大家请站起来”,“大家”和“everybody”的涵义是有区别的。在安乐哲教授看来,这个例子说明了中西方文化的差异,中国文化所强调的是一种人与人之间的关系性,人类是彼此依靠的,是相互关联的,了解一个人要从不同的社会关系上去了解。 /201007/108779南平去哪间医院检查早泄
