The challenge in managing e-waste will be in developing sustainable recycling tech- nologies that are able to address the volume and complexity of this waste using cost effective and ecologically sen-sitive methods. In this study, the capability or microorganism metabolic acids in dissolving the metallic tractions from waste printed circuit boards was examined. Several factors were considered in the examination of the activityof the acids-including secondary reactions, solution pH, temperature and the nature of ligands in solutions （or bioacid constituents）. The leaching tests were cgnducted ex-situ, using synthetic organic acids. Leaching was performed for periods of up to 6 hat 70-90 ℃ and 1000 r-min-1.展开更多

After the victory of the Revolution in 1959, Cuba tackled this challenge in a very original way, prioritizing the development of scientific and technical know-how and of an advanced scientific system. Moreover, it pursued this goal with an extremely open attitude, using characteristic Cuban resourcefulness while at the same time taking advantage of every possible support and collaboration. While the country was increasingly integrated into the Soviet system and the Council for Mutual Economic Assistance （COMECON）, and therefore benefited from a close collaboration with the Soviet Union and the Eastern European countries＇ higher education and scientific systems, nevertheless it constantly sought collaboration with scientists and institutions in other countries as well, in particular in the Western world. The most meaningful instance of this collaboration is the development since the 1980s of an advanced biotechnological and biomedical system, which was created independently by the Soviet Union. Quite remarkably, when the socialist system collapsed, though Cuba faced a critical situation, the strategic choice was made not to cut support to this scientific sector, but rather to reinforce it. At present Cuba produces and exports advanced and in some cases unique vaccines and drugs, and this sector ranks as third in the country＇s source of current hard currency.展开更多

Such principles and norms are a typical expression of Chinese people＇s wisdom in the analysis of their surroundings. However, traditional Chinese culture also contains some poisonous thinking that has been carefully nurtured by feudal rulers to maintain their power. In the practice of the great social changes of pre-1949 China, after repeated experience, people gained a relatively clear and comprehensive understanding of traditional Chinese culture： it should neither be totally affirmed nor totally rejected. Rather, we should analyze it concretely, endeavoring to separate the dross from the essence. In late Qing and Republican China, traditional culture was continuously handed on and renewed, and this process will be carried on and on.展开更多

The victory of the October Revolution turned socialism from an ideal into a reality and brought Marxism to a new stage： the stage of Leninism. The October Revolution changed the direction of world history and the Chinese revolution, a continuation of the October Revolution, became part of the proletarian-socialist world revolution. Any talk about Marxism in isolation from China＇s characteristics is merely Marxism in the abstract, Marxism in a vacuum. We can put Marxism into practice only when it is integrated with the specific characteristics of our country and acquires a definite national form. Deng Xiaoping Theory comes down in one continuous line from Leninism and Mao Zedong Thought and is Marxism in practice with the characteristics of the times and national traits. The magnificent achievements in the development of contemporary Chinese society are the outcome of unwavering adherence to and development of socialism with Chinese characteristics. In the context of economic globalization, we are still living in a transitional time from capitalism to socialism, an era started with the October Revolution. The 21 st century will see the rejuvenation of socialism, for the replacement of capitalism by socialism is an inevitable trend of world history.展开更多

The Comintern was established on the theoretical foundation of the theory of world revolution, but it underestimated how long that would take. Despite being the unified organizational vehicle of the ＂World Communist Party,＂ the Comintern underestimated the complexity of relations between itself and each country＇s Communist Party, among these national Communist parties, and between Communist and social democratic parties. A classic example was the fact that although the Comintern developed close relationships with the Communist Party of China （CPC）, it underestimated the particularity of Chinese revolution.展开更多
