重庆市爱德华医院激素检查江北市看不孕不育医院那家好Keeping roofs cooler to cut energy costs想省钱?先帮你的房顶降温吧!The roof of a house can get pretty hot in the summer. Even if there is an insulated attic below, some of that heat can work its way into the living space. That can make air conditioners work harder and pump up electricity bills. But a thin, paint-like coating could help keep roofs cooler, a teen researcher finds. And in urban areas, widesp use of her new roofing treatment might even cut the formation of lung-irritating ozone on hot days.夏季炙热的太阳烤的屋顶奇热无比,尽管有有隔热作用的阁楼,但还是抵挡不住骄阳的高温穿透屋顶进入房间内。这可累坏了家里的空调,甚至还会有额外的电费账单等着付呢。但一位青年研究员发现一层薄薄的涂料就能帮助房顶凉爽下来。在市区内,尽管是很热的天气,使用她的新式屋顶隔热法即使在很热的天气下也能减少会对肺造成刺激的臭氧的形成。Shingles come in many colors, but dark ones are especially popular, says Jesseca Kusher. The 18-year old attends Spartanburg Day School in South Carolina. Like most dark objects, shingles absorb a lot of heat from sunlight. In the summer sun, they can easily reach 73.5° Celsius (164° Fahrenheit), she notes. If those shingles reflected more sunlight, they#39;d stay cooler. And that could help cut down on home cooling bills. According to the Environmental Protection Agency, air conditioning consumes about 5 percent of all the energy used in the ed States. Cooling buildings costs the nation about billion each year.据一位来自南加利福尼亚州斯帕坦堡走读学校的18岁学生Jesseca Kusher介绍,这种特殊的屋顶由多种颜色组成,黑色尤为受欢迎。像多数黑色物体一样,这种材质的屋顶吸收阳光热量。经过夏天太阳的照射后,他们能很容易的达到73.5摄氏度(164华氏摄氏度),如果这种屋顶能返射更多的光,那么他们能保持更加凉爽的状态。家用降温设备产生的额外费用也会因此减少。根据环境保护署提供的数据,美国每年在降温设备上就会消耗约110亿美元。Jesseca Kusher, an 18-year-old researcher from Spartansburg, S.C., invented a paint-on coating for roofing shingles. Her formula could reduce a home#39;s cooling costs and possibly cut ozone pollution in urban areas.Jesseca Kusher,一名来自斯帕坦堡走读学校的18岁学生发明了一种房顶隔热涂层。她的发明能减少一个家庭因制冷而产生的额外费用并同时降低市区的臭氧层污染物。So Jesseca looked into ways to make shingles reflect more light. She mixed tiny particles - a powder - made from any of several different substances into a clear paint-like coating. One coating got graphite, the same material in pencil lead. Another recipe included gypsum. That#39;s a soft mineral often found in the drywall干式墙 used in construction. She even tried adding mica. That#39;s a mineral used in some lampshades. It ily breaks into small, glittering flakes.Jesseca也尝试过寻找能让这种屋顶反射更多光的方法。她把由任意几种不同物质组合而成的粉状物,也就是微小粒子混合成一种类似涂料的东西。这种涂层包括黑铅(和铅笔芯一样的材料),另一种成分是石膏,这是一种常见于干式墙建筑中的软矿物材料,甚至她还尝试着加上云母,一种很容易被捣碎成闪亮的晶片的矿物。Each of these powders came in several colors. In each of Jesseca#39;s test recipes, her reflective powder accounted for 40 percent of the weight of the final mixture. She also prepared some of the paint-like coatings with no additive. That would let her judge whether a powder - versus the transparent goop it was added to - affected a shingle#39;s reflectivity, she explains.每一种粉状物都会放入几种不同的颜色,在jesseca的成分实验中,能进行反射的粉占最终混合物重量的40%。同时她也准备了无任何添加的类似涂料的东西,这样她能判断单纯的粉状物以及添加了透明物质的粉状物是否会对屋顶光的反射产生影响。译文属 /201506/379857重庆治疗宫颈肥大的妇科医院 BRUSSELS — The European Union’s antitrust chief on Wednesday formally accused Google of abusing its dominance in web searches to the detriment of competitors and began official proceedings into whether its Android smartphone software forces phone makers to favor the company’s own services and applications.布鲁塞尔——欧盟反垄断最高官员周三正式指控谷歌(Google)利用其在网络搜索方面的主导地位,损害竞争对手,并将就Android智能手机软件是否强制手机制造商偏袒谷歌自身务和应用的做法提起诉讼。“If the investigation confirmed our concerns, Google would have to face the legal consequences and change the way it does business in Europe,” said Margrethe Vestager, the European Union competition commissioner.“如果调查结果实了我们的忧虑,谷歌将不得不面临法律后果,并且改变它在欧洲的商业模式,”欧盟竞争事务专员玛格丽特·韦斯塔格尔(Margrethe Vestager)说。The abuse charge focused on accusations that Google diverts traffic from its rivals to favor its own products and services, particularly websites for shopping. That led the European Commission to issue a set of formal charges, known as a statement of objections.指控主要集中在指责谷歌从竞争对手分流流量,偏向其自身产品和务,尤其是购物网站。这导致欧盟委员会发布了一套被称为异议声明的正式指控。A large number of online operators have complained about Google in other areas, like travel and mapping. Ms. Vestager said that the inquiry might eventually expand beyond shopping sites.许多在线运营商已经抱怨过谷歌在旅游和地图等其他领域的做法。韦斯塔格尔说调查或将最终扩展到购物网站以外的领域。The commission also said it was stepping up a separate investigation into whether phone makers that agree to use Android — and that also want Google applications like YouTube — face contractual requirements to place those applications and other Google-branded applications in prominent positions on a mobile device.委员会还称,其正在加强一项独立调查,针对同意使用Android系统并希望使用YouTube等谷歌应用的手机制造商,调查是否存在合同要求它们在移动设备的显著位置放置谷歌品牌应用。 /201504/370539巴南做孕前检查怎么才能免费

黔江照影痛不痛 Smallpox Inoculation人痘接种Smallpox inoculation or variolation was a great invention of medicine in ancient China. Inoculation against smallpox using material from small-pox patients was probably first practiced by the Chinese in the 10th century. A story was recorded that a Song Dynasty (960-1279) chancellor of China, Wang Dan,summoned physicians from all over the country to try to find some remedy for smallpox. From Mount Emei in Sichuan, a Taoist hermit, known as a ; miracle-working doctor; brought the technique of inoculation and introduced it to him.However, the first clear and credible reference to smallpox inoculation in China comes from Douzhen Xinfa written in 1549 by Wan Quan. Inoculation, according tothe historical records, was not widely practiced in China until the reign of Emperor Longqing (1567-1572) during the Ming Dynasty. Powdered smallpox scabs were blown into the noses of the healthy, and they would then develop a mild case of the disease and from then on were immune to it. During the seventeenth century,the practice sp to the Turkish regions, and then to the European countries. The French philosopher Voltaire once praised, ;I am informed that the Chinese have practised inoculation in the past hundred years; this is a great precedent and ex-ample set by the Chinese nation considered to be the most intelligent and courteous in the world. ;人痘接种预防天花是中国古代医学家的伟大发明。中国人可能早在10世纪已懂得利用天花患者的病毒来接种的人痘接种法。有史书记载了一个故事:宋朝宰相王旦曾召集全国各地医师商议防治天花的方法,随后有一个被称为“神医”的四川峨眉山道教隐士将人痘接种术传给了王旦。不过,中国关于人痘接种最早的明确可信的记载来自明代医学家万全1549年的《痘疹心法》一书。据史料记载,人痘接种被广泛应用是在明朝隆庆年间(1567一1572)。将天花痘痂粉末吹人健康者的鼻孔,使其染病但症状较轻,痊愈之后便会终身对天花具有免疫力。17世纪,这一方法流传至土耳其一带,后又传至欧洲各国。法国哲学家伏尔泰这样赞扬人痘接种:“我听说一百年来,中国人一直就施用人痘接种法;这是被认为全世界最聪明、最讲礼貌的一个民族的伟大先例和榜样。” /201601/419336璧山潼南区痛经多少钱重庆治疗子宫肌瘤医院哪家好
