完美儿媳,你也可以做到

<正>"我的婆婆对我一直都不是很满意,"马乔里说,"她要是看见我穿红色的衣服,就会告诉我‘你还是穿黑色的吧’,黑色的看起来更苗条一些;我给孩子穿上了一件夹克衫,她非得给他套上羽绒服,因为她觉得孩子穿夹克会冷;如果我做饭油多了一些,她就会给我来一次胆固醇的‘指导’课程。我已经40多岁了,但是她还是拿我当个孩子。我真的不想再听见她的唠叨了。"     

推荐一个耐盐碱速生中林号杨树品种

在多年的中林号速生杨推广中，调查发现了一种粗皮中林号杨树，在土壤可溶性含盐量高达0.737％的盐碱地上仍能正常生长，在相同土壤条件下其单株活立木蓄积量比中林46号杨增长300％以上，充分体现其速生性，为我市轻盐碱地造林增加一个速生杨品种。     

Ethanol can contribute to energy and environmental goals

To study the potential effects of increased biofuel use, we evaluated six representative analyses of fuel ethanol. Studies that reported negative net energy incorrectly ignored coproducts and used some obsolete data. All studies indicated that current corn ethanol technologies are much less petroleum-intensive than gasoline but have greenhouse gas emissions similar to those of gasoline. However, many important environmental effects of biofuel production are poorly understood. New metrics that measure specific resource inputs are developed, but further research into environmental metrics is needed. Nonetheless, it is already clear that large-scale use of ethanol for fuel will almost certainly require cellulosic technology.     

Perfluorochemical emulsions can increase tumor radiosensitivity

An oxygen-carrying perfluorochemical emulsion enhanced the effectiveness of radiation therapy in two transplantable solid tumors in mice. The perfluorochemical emulsion had no effect on tumor growth after x-irradiation, but delayed tumor growth significantly when administered to oxygen-breathing mice before or during irradiation.     

梅花也能这样卖

重庆市江北区复胜镇的一个小山村，村名原叫银盆村，到了2002年，改名叫梅花村。叫梅花村不是为了好听，而是梅花和村民的生活已经紧密地联系到了一起。
