To investigate the effects of SO2 and NOx reductions on the particulate sulfate and nitrate concentrations as well as their size distributions, size-segregated aerosol samples were collected using micro-orifice uniform deposit impactors （MOUDIs） at urban and downwind rural sites in Beijing before and after full-scale controls. During the sampling period, the mass concentrations of fine particles （PMI.s） at the urban and rural sites were 94.0 and 85.9 p.g m-3, respectively. More than 90% of the sulfates and 60% of nitrates formed as fine particles. Benefiting from the advantageous meteorological conditions and the source controls, sulfates were observed in rather low concentrations and primarily in condensation mode during the Olympics. The effects of the control measures were separately analyzed for the northerly and the southerly air-mass-dominated days to account for any bias. After the control measures were implemented, PM, sulfates, and nitrates were significantly reduced when the northerly air masses prevailed, with a higher percentage of reduction in larger particles. The droplet mode particles, which dominated the sulfates and nitrates before the controls were implemented, were remarkably reduced in mass concentration after the control measures were implemented. Nevertheless, when the polluted southerly air masses prevailed, the local source control measures in Beijing did not effectively reduce the ambient sulfate concentration due to the enormous regional contribution from the North China Plain.展开更多

The results of this monitoring show that high concentrations of PM2.5 pollution exhibited a regional pattern during the monitoring period （1 June-30 October 2008）. The PM2.5 mass concentrations were 53 μg m-3, 66 p.g m-3, and 82 μg m-3 at the background site, in Beijing, and in the Beijing-Tianjin-Hebei urban agglomerations, respectively. The PM2.5 levels were lowest during the 2008 Olympic Games （8-24 August）： 35μg m-3 at the background site, 42 μg m-3 in Beijing and 57 μg m-3 in the region. These levels represent decreases of 49%, 48% and 56%, respectively, compared to the prophase mean concentration before the Olympic Games. Emission control measures contributed 62% 82% of the declines observed in Beijing, and meteorological conditions represented 18%-38%. The concentration of fine particles met the goals set for a ＂Green Olympics.＂展开更多

Systematic doping with AAS occurred in the German Democratic Republic （GDR） from 1965 to 1989 which assisted that country to win many medals at Olympic Games, especially in female events. Currently, AAS are the most frequent category of prohibited substances detected in the urine of athletes both globally and at the last two Summer Olympic Games. Scientific confirmation that AAS are effective in enhancing sports performance was difficult because ethical approval was difficult for research involving male subjects taking massive doses of androgens as some athletes and bodybuilders did. Methods to detect AAS have evolved gradually over the past three decades and currently, despite an impressive array of sophisticated analytical equipment and methods, anti-doping authorities and analytical scientists continue to face challenges as have occurred from the use by athletes of designer AAS during the past few years. The future development and use of selective androgen receptor modulators （SARMs） can be anticipated to pose problems in the years ahead. Endocrinologists should be aware that on occasions, replacement testosterone （T） therapy may be authorized in sport as a therapeutic use exemption （TUE） and these circumstances are discussed.展开更多

This assumption comes from “common sense”, as a logical conclusion arising from the fact that host cities “inspire” and stimulate lifestyle changes. Benefits are also expected on tourism, self-image, architecture and the economy of the country as a whole. But are these expectations real and evidence-based? What parts of these “facts” are concrete and which ones are not? This paper suggests available ways of quantifying positive effects of hosting an Olympic Game, and puts the focus of this approach on the Rio de Janeiro 2016 Olympic Games and their true legacy, seeking scientific certainties.展开更多

[Method] Based on the analysis of particulate matter online observation data and meteorological data during the corresponding period in Chinese environmental science college, Hysplit Back trace model and Numerical weather prediction graphs, and combined with the different analytical methods on meteorological flow fields, a typical process of particles in Beijing during early 2008 Olympic Games was studied. [Result] The results indicated that during the ascent stage of PM2.5 concentration, the PM showed gradually aging phenomena; the process controlled by large scale synoptic system mainly. And the weak wind and the high humidity were not in favor of dispersion; the prolonged southerly air mass to bring the pollutant of Hebei, Taijin and Shandong to Beijing; mixing height and temperature curve took the importance role to the pollution. [Conclusion] The study provided theoretical basis for the discussion on factors influencing the production and elimination of particles in the air pollution process.展开更多

In the ancient religions, fasting was observed as common religious practice associated with many religious festivals. Fasting was also observed in the Judaism and Christianity as part of the religious belief. Therefore, Islam has also prescribed fasting for Muslim in the form of a-month long period of obligatory acts of worship. Ramadan is the ninth month of the Muslim calendar, during which they observed the fasting among daylight hours. The paper has explored significance of Ramadan and impact it had on Muslim athletes during the London 2012 Olympic Games. The Olympic Games were scheduled during the month of Ramadan and the impact of the Olympic Games on Muslim athletes, visitors, and viewers was described, because main Olympic events were scheduled during the breaking of the fast. This paper presents the findings of the primary research undertaken to assess the views and opinions of both the Islamic religion and other religions, concerning the impact of religious festivals on the Olympic Games. The results concluded that most of the people have no idea that there could be an impact of religious festivals on the Olympic Games.展开更多

With the constant development of the Olympic Games, people have proposed higher requirements for it and the reformation is eagerly needed and the reformation is mainly concentrated on the item setting. According to a large amount of theoretical research to the item setting of Olympic Games in academia, there is big issue about the item setting for the current Summer Olympic Games which has sustained for a long time. Its practical representations are the contradiction between narrowing the scope of the Olympic Games and borrowing in the new items and the contradiction of gender equality in item setting and also the contradiction of balancing the business value and social value. Therefore, this thesis will mainly study on the evolution and value of the item setting of the Summer Olympic Games and propose reasonable improvement measures for the issue of the item setting, combining with the practical conditions, and thus to better promote the sustain development of the Summer Olympic Games.展开更多

By comparing the data of a set of standard multi-element observation stations with the data of multiple measured traffic stations, the outliers of each element data at each station were analyzed. It could provide data support for the maintenance of Zhangjiakou traffic meteorological observation station and a guarantee for the accuracy of forest service during Beijing Winter Olympic Games period.展开更多

Wrestling has unique position among Olympic disciplines in India, from being provider of first individual medal to newly independent nation to lately becoming most significant contributor in medal tally. This coming of age of Indian wrestling team with double medal tally in the last Olympics has been outcome of long and steady journey of Indian wrestling team over a period of 40-50 years and numerous Summer Olympic Games. However, this journey of Indian wrestling team in the Olympics is also a stoW of significant twist and turn, near misses and also of glow. So this article covers the entire saga of Indian wrestlers at highest sporting event of world--Olympic Games, from inception of first Indian team of mere three grapplers to latest Olympics with debut of first Indian female grappler in Olympic arena. This history is written by sweat and hard work of Indian grapplers with its own highs and lows.展开更多
