A method is presented to determine significant frequencies of oscillations of cavitation structures from high-speed camera recordings of a flow around a 2-D hydrofoil. The top view of the suction side of an NACA 2412 hydrofoil is studied in a transparent test section of a cavitation tunnel for selected cloud cavitation regimes with strong oscillations induced by the leading-edge cavity shedding. The ability of the method to accurately determine the dominant oscillation frequencies is confirmed by pressure measure- ments. The method can resolve subtle flow characteristics that are not visible to the naked eye. The method can be used for non- invasive experimental studies of oscillations in cavitating flows with adequate visual access when pressure measurements are not available or when such measurements would disturb the flow.

俄罗斯月球-全球-1着陆器将于2015年发射,主要目的是测试月球着陆器的软着陆技术。月球-全球-2轨道器计划于2016年发射,将先后在距月面500km、150km和50km的高度上飞行。2017年计划发射的月球-资源-1着陆器,将是搭载大量科学载荷和承担相应探测任务的月面科学研究站。与苏联时期所研制的月球车相比,分别在月球-资源-2和月球-资源-3着陆器上搭载的俄罗斯新一代月球车——月球车-3和月球车-4,将携带更加先进的科学仪器,能够精确分析采集样品的化学成分、光谱特征等。其运行模式包括行走、勘察、接近目标、接触目标和样品采集与分析,将对月球极区表面环境进行全面探测。结合对俄罗斯"月球-全球"和"月球-资源"探月任务的介绍,针对中国的探月计划提出如下建议:探月任务的实施,应以科学研究为主要目的,以建立月球基地为目标,借鉴国外探月技术,开展国际合作,为形成独立的月球科学体系打下坚实基础。

从理论和实验上研究了77K和300K温度下,本征型半导体InSb,Hg_(1-x)Cd_xTe,Hg_(1-x)Mn_xTe和高掺杂Hg_(1-x)Cd_xTe在2.5～50μm波段范围内的自由载流子吸收,结果表明:对于所研究的三种本征型样品,均是极性光学声子散射起主要作用,对于InSb还应考虑声学声子和电离杂质散射。对有缺陷的Hg_(1-x)Mn_xTe样品,理论计算的自由载流子吸收系数与实验值不一致,表明存在附加的散射机制,对高掺杂Hg_(1-x)Cd_xTe的研究证实了这一假设。还讨论了非弹性电子-声子散射机制的起因,估算了特性参数。

Frontiers of History in China 2014年第2期9卷 321-326页

作者： rostislav Berezkin Fudan University

The new book by vladimir Uspensky （alternatively, Uspenskiy）, Professor and Chair of the Department of Mongolian and Tibetan Studies, Faculty of Asian and African Studies of Saint Petersburg State University （Russia）, deals with various aspects in the history of Tibetan Buddhism in Beijing; the time is mainly the period from the middle seventeenth to the early twentieth century. During the reign of the Qing dynasty, the ruling class, namely Manchu and Mongolian nobility, patronized Tibetan Buddhism. This aspect of Qing history is studied too little in Chinese and foreign works, and Uspensky＇s book fills this lacuna. One can see that the author successfully achieved his aim, as he has drawn a vivid picture of institutions and cultural activity among Tibetan Buddhists in Beijing.

AIM: To investigate whether selected single nucleotide polymorphisms (SNPs) in miR-196a2, miR-27a and miR146a genes are associated with sporadic colorectal cancer (CRC).METHODS: In order to investigate the effect of these SNPs in CRC, we performed a case-control study of 197 cases of sporadic CRC and 212 cancer-free controls originating from the Central-European Caucasian population using TaqMan Real-Time polymerase chain reaction and allelic discrimination analysis. RESULTS: The genotype and allele frequencies of SNPs were compared between the cases and the controls. None of the performed analysis showed any statistically significant results. CONCLUSION: Our data suggest a lack of association between rs11614913, rs895819 and rs2910164 and colorectal cancer risk in the Central-European Caucasian population, a population with an extremely high incidence of sporadic colorectal cancer.
