    Chapter 7 Olympic Cities Chapter 7 Olympic Cities 173 Section I Host City — Beijing Beijing, the host city of the Games of the XXIX Olympiad, will also host the 13th Paralympic Games. In the year 2008, Olympic volunteers, as ambassadors of Beijing, will meet new friends from throughout the world. The Chinese people are eager for our guests to learn about our city and the people who live here. I. Brief Information of Beijing Beijing, abbreviated“ JING”, is the capital of the People’s Republic of China and the center of the nation's political, cultural and international exchanges. It is a famous city with a long history and splendid culture. Some 500,000 years ago, Peking Man, one of our forefathers, lived in the Zhoukoudian area of Beijing. The earliest name of Beijing 174 Manual for Beijing Olympic Volunteers found in historical records is“JI”. In the eleventh century the state of JI was subordinate to the XI ZHOU Dynasty. In the period of“ CHUN QIU” (about 770 B.C. to 477 B.C.), the state of YAN conquered JI, moving its capital to the city of JI. In the year 938 B.C., Beijing was the capital of the LIAO Dynasty (ruling the northern part of China at the time), and for more than 800 years, the city became the capital of the Jin, Yuan, Ming and Qing dynasties. The People’s Republic of China was established on October 1, 1949, and Beijing became the capital of this new nation. Beijing covers more than 16,000 square kilometers and has 16 subordinate districts (Dongcheng, Xicheng, Chongwen, Xuanwu, Chaoyang, Haidian, Fengtai, Shijingshan, Mentougou, Fangshan, Tongzhou, Shunyi, Daxing, Pinggu, Changping and Huairou) and 2 counties (Miyun and Yanqing).

  • Transmission of Han Pictorial Motifs Into the Western Periphery: Fuxi and Nüwa in the Wei-Jin Mural Tombs in the Hexi Corridor*8
    DOI: 10.4312/as.2019.7.2.47-86 47 Transmission of Han Pictorial Motifs into the Western Periphery: Fuxi and Nüwa in the Wei-Jin Mural Tombs in the Hexi Corridor*8 ∗∗ Nataša VAMPELJ SUHADOLNIK 9 Abstract This paper examines the ways in which Fuxi and Nüwa were depicted inside the mu- ral tombs of the Wei-Jin dynasties along the Hexi Corridor as compared to their Han counterparts from the Central Plains. Pursuing typological, stylistic, and iconographic approaches, it investigates how the western periphery inherited the knowledge of the divine pair and further discusses the transition of the iconographic and stylistic design of both deities from the Han (206 BCE–220 CE) to the Wei and Western Jin dynasties (220–316). Furthermore, examining the origins of the migrants on the basis of historical records, it also attempts to discuss the possible regional connections and migration from different parts of the Chinese central territory to the western periphery. On the basis of these approaches, it reveals that the depiction of Fuxi and Nüwa in Gansu area was modelled on the Shandong regional pattern and further evolved into a unique pattern formed by an iconographic conglomeration of all attributes and other physical characteristics. Accordingly, the Shandong region style not only spread to surrounding areas in the central Chinese territory but even to the more remote border regions, where it became the model for funerary art motifs. Key Words: Fuxi, Nüwa, the sun, the moon, a try square, a pair of compasses, Han Dynasty, Wei-Jin period, Shandong, migration Prenos slikovnih motivov na zahodno periferijo: Fuxi in Nüwa v grobnicah s poslikavo iz obdobja Wei Jin na območju prehoda Hexi Izvleček Pričujoči prispevek v primerjalni perspektivi obravnava upodobitev Fuxija in Nüwe v grobnicah s poslikavo iz časa dinastij Wei in Zahodni Jin (220–316) iz province Gansu * The author acknowledges the financial support of the Slovenian Research Agency (ARRS) in the framework of the research core funding Asian languages and Cultures (P6-0243).

Faculty of Geomatics,Lanzhou Jiaotong University, China 2. National-Local Joint Engineering Research Center of Technologies and Applications for National Geographic State Monitoring, China 3. Gansu Provincial Engineering Laboratory for National Geographic State Monitoring, China Abstract: Color steel plate building has the characteristics of beautiful appearance, low cost, light weight and fast construction speed. It is an important product in the rapid development of the city. It is widely distributed in urban villages, urban fringe, new technology development zones, construction sites and other plots.Its spatial distribution has obvious aggregation characteristics and regularity. This paper takes the four main urban districts of Lanzhou as the research area. Based on the 2017 remote sensing image and urban regional vector boundary data, the GIS platform is used to obtain the color steel plate building vector data by human-computer interaction interpretation, using buffer analysis method, spatial statistical method, etc, the spatial distribution characteristics of color steel plate buildings in the study area were discussed. The results show that the building density of color steel plate decreases with the distance from the Yellow River, which is consistent with the logarithmic model. As the distance from the city center increases, the overall decline, rising at 4-6km, 12-16km.

Dynamics of Disintegration: The Later Han Empire (25-220CE) & Its Northwestern Frontier Abstract As a frontier region of the Qin-Han (221BCE-220CE) empire, the northwest was a new territory to the Chinese realm. Until the Later Han (25-220CE) times, some portions of the northwestern region had only been part of imperial soil for one hundred years. Its coalescence into the Chinese empire was a product of long-term expansion and conquest, which arguably defined the egionr 's military nature. Furthermore, in the harsh natural environment of the region, only tough people could survive, and unsurprisingly, the region fostered vigorous warriors. Mixed culture and multi-ethnicity featured prominently in this highly militarized frontier society, which contrasted sharply with the imperial center that promoted unified cultural values and stood in the way of a greater degree of transregional integration. As this project shows, it was the northwesterners who went through a process of political peripheralization during the Later Han times played a harbinger role of the disintegration of the empire and eventually led to the breakdown of the early imperial system in Chinese history.

    Australian Journal of Basic and Applied Sciences, 5(6): 704-717, 2011 ISSN 1991-8178 Regeneration, Cardenolide and Flavonoid Production from In Vitro Cultures of Cynanchum acutum L. (Asclepiadaceae) 1Ahmed A. El-Bakry, 2Ezzat Genady, 1Safeyia M. Ghazi and 1Shams A. Rafat 1Botany Department, Faculty of Science, Helwan University, Cairo, Egypt. 2Pharmacognosy Department, Faculty of Pharmacy, Al-Azhar University, Cairo, Egypt. Summary: Callus was produced from hypocotyl sections of in vitro germinated seedlings of Cynanchum acutum on Murashige and Skoog media (1962) containing 0.5 - 4.0 mg/l a-Naphthalene acetic acid in combination with 0.2-1.0 mg/l Benzyl adenine. After 12 weeks in culture both fresh and dry weights (g) were significantly higher on 0.5 mg/l NAA and 0.2 mg/l BA. Cardiac glycoside concentration was highest (1.2 mg/g DW) on the same growth regulators combination. Flavonoids were highest (0.198 mg/g) on 0.5mg/l NAA and 1.0 mg/l BA. Twenty eight weeks old callus gave highest cardiac glycosides (1.3 mg/g) on media lacking BA and 0.5 mg/l NAA. Flavonoids concentration (0.27 mg/g) was highest on the same auxin concentration in the presence of 0.2 mg/l BA. Regeneration from callus cultures was obtained when 8-weeks old callus was subcultured on MS hormone free media for 6 weeks. Shoots were rooted on MS supplemented with 0.1 mg/l NAA and acclimatized in growth chamber. Adventitious shoots showed significantly higher CG (6.5 and 4.3 mg/g) than the wild plants (2.8), while regenerants gave comparable concentration (2.3) to the wild.
