A multi-analytical approach for the study of brazilwood and its lake pigments was carried out based on historically accurate reconstructions. Recipes for brazilwood lakes from the fifteenth century technical text Livro de como se fazem as cores and the Winsor & Newton nineteenth century colourman's archive were reproduced and compared. Both primary sources allowed for the successful preparation of brazilwood lake pigments with colours that vary from light pink to dark red. The main steps and ingredients for the manufacture of these pigments were common in both sources, particularly the addition of Al3+ in the form of alum, and calcium carbonate (chalk). Reconstructions revealed that the latter acts as a pH buffer and filler, controlling the pH at which the lake pigment precipitates. The main difference between the two sources is that the nineteenth century recipes give the quantities for all ingredients, the precise temperatures and time, and achieved higher relative pigment yields (75% versus 45%). Full chemical characterisation of the reconstructions provided detailed information on the individual steps in the pigment manufacture and revealed that the presence of calcium sulphate dihydrate (gypsum) in the final pigment was a result of its formation in situ. Infrared, reflectance, and fluorescence spectroscopy proved to be essential and complementary techniques: while infrared was used to characterise additives and binders, reflectance and fluorescence data were fundamental for identifying the chromophore. The pigments and paints produced can now be used as standards for the identification and investigation of brazilwood lake pigments found in artworks. 相似文献

全球化语境下,市场经济的全球扩张、国际组织的迅猛发展、跨国公司的无国界经营、人权的滥觞、新科技革命的负面效应都对我国国家主权构成了挑战。为了回应挑战,我们应当积极融入全球化,加强国际合作,反对霸权主义和强权政治;加强党的执政能力建设;转换政府角色,从“划桨”转为“操舵”;消弭“化乡愁”,实现中华民族化的现代转变。 相似文献

“自然无为”是老子哲学思想的显著特色。老子思想中“自然无为”命题并不是无所作为,随心所欲,而是要以辩证法的原则指导人们的社会生活,帮助人们寻找顺应自然、遵循事物客观发展的规律。结合道法自然的生态理念、清静无为的处世哲学、自然纯真的人生旨趣等若干问题,揭示老子“自然无为”这一思想的现代价值。 相似文献

AbstractWhile most equate Mexican Olympism with the 1968 Olympic Games, few know the drama of the event that laid its groundwork. From the creation of the Ministry of Public Education in 1921, cultural and military leaders heavily invested in sports infrastructure to help regenerate its rural masses, but by the 1940s, post-war modernizers sought the hosting of large international athletic events to boost its prestige, foment national pride, and prove to the world it was ready to springboard into modernity. This paper recounts the triumphs, betrayals, corruption, and politics of Pan-American sport and the Olympic movement in Mexico in the 1940s and 1950s that culminated in the improbable success of the 1955 Mexico City Pan-American Games. 相似文献

AbstractThe Olympic Games of the modern era are powerful global mediated events. Olympic cities receive an overwhelming examination by world media. As the 2016 Olympic host, Rio de Janeiro has been given an enormous amount of attention, both by the international media and researchers who looked at the urban spaces of Rio, the struggles over the hegemony of the city and the social meanings the Olympics bring to the host city’s citizens. However, studies over the historical relationship between Rio, sport and media are rare. This paper addresses the historical uses of the term Olympic by Brazilian media during the late nineteenth and the early twentieth centuries. By looking at the main articles in the newspapers of these periods, we examine the extent to which ideologies over sports have changed the way the Olympics were represented in Brazil’s national imaginary. We demonstrate how the use of expressions associated with the Olympics historically generated a closer appreciation of these events by the public. We also show how political authorities appropriated the Olympics for their own benefit. The paper concludes by asking whether or not the historical lessons from the early Olympic ideas in Brazil have been learned by the 2016 Rio Games organizers. 相似文献
