The optical and morphological properties of resveratrol were investigated. This nontoxic fluorescent natural material, emitting in the visible blue light, was used as an optical marker, enabling the enhancement of the image contrast coming from relief pictures marked on challenging surfaces. By applying appropriated imaging softwares, this marker was verified to be very useful in the latent fingerprint recognition deposited on different wood surface types, mainly those with high level of roughness, where conventional forensic materials do not allow effective fingerprint image visualization. 相似文献

Fair trade represents an innovative approach to make the rules of global trade work for disadvantaged producers in the South and for sustainable development. But who are the real beneficiaries of fair trade? Has fair trade resulted in any discernible improvements in the lives of small coffee producers and their communities? This paper examines the effectiveness of fair trade as a development tool and the extent of its contribution to the alleviation of poverty in coffee-producing regions of Nicaragua. The paper argues that it is crucial to analyse the experiences and problems of small coffee producers and producer organisations involved in the fair trade market to ensure that the objectives and claims of fair trade are achieved in practice. The study concludes that there are limits to the extent to which fair trade can significantly raise the standard of living of small coffee producers because of factors such as the debt problems faced by cooperatives, lack of government support, and volatile international coffee prices. 相似文献

In the battle to curry the favour of the fast-food consumer,McDonald's collided head on with its competitor Burger Kingat the beginning of this year; the key question in this disputewas whether Burger King was entitled to use the famous characterRonald McDonald in its commercials or whether, by doing so,Burger King was infringing the trade mark rights of McDonald's. 相似文献

Making a first sketch of philosophical issues arising fromEuropean Community law I want to present a series ofmore or less obvious, and more or less interrelated dilemmas,or even double binds.(i) Deepening the community becomes incompatible withwidening membership. (ii) National states seem bothnecessary for and obstructive in articulating transnationalproblems. (iii) The more democracy is needed as a warrantfor the public exercise of political power in Europe, themore the very concept of democracy on a European scaleevades understanding. (iv) European unity presupposes aunifying rule of law, while member states have radicallydifferent conceptions of this principle. (v) Even the verycore of European integration, the common market, is subjectto two conflicting and, indeed, incompatible doctrines ofcompetition. In explaining the nature of each dilemma I willtry to take my cue from the Maastricht Treaty wherever thisseems suitable. Then I will elaborate on the jurisprudentialproblems involved in it. Finally, each section will be closedby an attempt to state the nature of these problems inphilosophical terms. 相似文献
