粉尘薄膜爆轰

与普通爆轰不同，粉尘薄膜爆轰波前氧化剂与燃料处于分离状态．由于激波作用下壁面燃料的注入才于壁面附近形成燃烧的粉尘云，燃烧释放的热使激波自持形成粉尘薄膜爆轰。本文在长2、8m，横截面20mm×20mm的方型水平激波管中对此类爆轰进行了实验研究．并根据作者建立的模型对其二维结构进行了数值模拟。     

Protruded lumbar intervertebral nucleus pulposus in a 12-year-old girl who recovered after nonsurgical treatment: a follow-up case report

Restless legs syndrome affects millions, but most healthcare providers don't know it exists. Its sleep-deprived victims are plagued by indescribable crawling sensations in their legs that occur at night and that are only relieved by moving the legs. Many home healthcare clients, already challenged by their primary illness, are also affected by the persistent symptoms of Restless Legs Syndrome. It is important that home care nurses learn about Restless Legs Syndrome-what it is, how to assess it, and what can be done about it.

An inhibitor of DNA topoisomerase I from Xenopus laevis ovaries

A novel, heat-resistant and Pronase-sensitive, inhibitor of eukaryotic DNA topoisomerase I has been purified from Xenopus laevis ovaries. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of the most purified fraction revealed three bands with apparent molecular masses of 25, 28.5, and 33.5 kDa. The 25- and 33.5-kDa peptides recovered from an SDS-PAGE gel inhibited X. laevis DNA topoisomerase I. The purified inhibitor was specific to DNA topoisomerase I and did not inhibit other DNA enzymes tested. The inhibitor blocked the catalytic activity of DNA topoisomerase I by interacting with the enzyme, rather than by competing for binding sites on substrate DNA. Binding of DNA topoisomerase I to substrate DNA was blocked by the inhibitor, as was the cleavage reaction catalyzed by DNA topoisomerase I. Inhibition of DNA topoisomerase I was relieved by divalent cations Ca2+, Mg2+, or Mn2+.     

TNT-RDX混合废水处理的实验研究——生物-吸附法

介绍了在２５￣３５℃的温度下，用厌氧－兼氧－水生生物－吸附组合工艺处理ＴＮＴ和ＲＤＸ混合废水的方法，进行了日处理量为６０￣９００Ｌ的实验室放大实验。当ＴＮＴ和ＲＤＸ混合废水总浓度为４￣１２ｍｇ／Ｌ时，经过该工艺处理后可达到国家排放标准。其中厌氧－兼氧能去除废水中８０％以上的ＴＮＴ和ＲＤＸ，水生生物（水葫芦）对ＴＮＴ及ＲＤＸ也有一定的降解效果，最后用活性炭吸附可以实现深度处理。
