This article fashion＂（＂kitaischina＂） reign of Peter the First demonstrates the role Russo-Chinese cultural examines special features of ＂Chinoiserie＂ or ＂Chinese in Russia from the late 17th to the early 18th century： The It discusses this cultural phenomenon＇s historical origins, of Chinese luxury goods and art objects in the era＇s exchange, and illustrates how Chinese decorative arts were used in Russian palaces. While Chinoiserie in Russia was influenced by similar trends in Western Europe, it was rooted in the unique history of regular contacts between Russia and the Qing Empire. Chinese objects not only appeared as commodities in the higher levels of Russian society, they also contributed to the prestige of the Russian state. Peter the First had a political purpose behind the collection, display and imitation of Chinese art objects in Russian palaces, as these practices demonstrated the growing wealth and power of newly established Russian Empire, which enjoyed trade connections with the Qing Empire. While contemporary perceptions of China in Russia were derived mostly by the exotic images of export art, ethnographic collections of genuine Chinese utensils, which were founded during that period, also contributed to Russian views of China. This research uses a comprehensive methodology, combining studies of material objects preserved in Russian museums and written sources, including archival records.

In this paper, I analyze pictorial representations of the Buddhist story of Mulian rescuing his mother in China, Japan, and korea in the pre-modern and early modern periods. I have collected several pictorial versions of the Mulian story in these countries, and comparison shows close proximity of several such works. All of them are related to the narrative texts that represent elaboration of the originally scriptural story (it originated in the apocryphal Buddhist scripture that circulated in China) in vernacular languages. Images of the Mulian story in the countries of East Asia had diverse nature: they could appear as separate scenes in devotional religious paintings, multi-scene handscrolls, and illustrations in the manuscripts and editions. I argue that the subject of Mulian rescuing his mother was of primary importance in the popularization of Buddhist ideas among different layers of society. The related images were used for both storytelling and reading practices and helped different audiences to comprehend the Mulian story.

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.

In this study,we present the development of microtubular solid oxide fuel cells(MT-SOFC)with a two-layer cathode:a composite cathode functional layer(CFl)adjacent to the buffer layer(Bl)and a cathode current-collecting layer(CCCl).CFl consists of a mixture of Bl material Ce_(0.9)Sm_(0.2)O_(1.95)(SDC)and perovskite Ba_(0.5)Sr_(0.5)Co_(0.75)Fe_(0.2)Mo_(0.05)O_(3-δ)(BSCFM5),which has a high exchange rate with *** widely used cathode material la_(0.6)Sr_(0.4)Co_(0.2)Fe_(0.8)O_(3-δ)(lSCF)with high electrical conductivity was used as the CCCl.A significant increase in the peak power density of the MT-SOFC to 1.2 W/cm^(2)at 850℃ was achieved using the proposed two-layer cathode.

The new book by Wilt l. Idema is a collection of English translations of six precious scrolls （baojuan 宝卷） from Western Gansu, also known as the Gansu Corridor or Hexi （河西, meaning the land to the west of the Yellow River/. It continues Idema＇s work on the English translation of the most important works of Chinese popular literature （mainly related to oral storytelling practices）, many of which still remain understudied or completely unknown in Western sinology. None of these texts has ever been translated into English or other Western languages before.

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.
