The success of any international transaction depends on whether the involved parties are familiar with each other or not. A good knowledge of the economic rules used worldwide is the key factor in finding one’s way into the international market. As one of the most promising Third World countires ,China, with her pending entry into WTO,is in urgent need of human resources familiar with the international economic rules. Besides, China’s West Development Project brings China’s vast interior closer to overseas enterprises and as a result versatile local talents well versed in these rules are in great demand. As Incoterms 1990 is a convenient guide to the international economic rules, it is an ideal coursebook for the training of these people. This paper highlights the merits of Incoterms 1990 and thus acquaints readers with these rules.展开更多

This kind of filters are not only characterized by high-transparency, but also by high - reflection ,therefore , it is superior to the common equal thickness interference system with quarter wavelength . it is easier to control the manufacturing techniques of the new design as compared with that of interference filter of non- quarter wavelength.展开更多

We assess promising directions and negative effects of development of agglomerated formations and zones of their influence in the Republic of Kazakhstan as a region having an advantageous geostrategic position in the Eurasian space. In Kazakhstan, the current process of urbanization has a multiple- vector nature, and the course of formation of urban agglomerations provides convincing evidence of an increase in their share in settlement and in the total population. It is agglomerated forms of urban development that are a kind of indicator of the onset of maturity in settlement, specifying key points of the socio-economic space, namely: cores of regions, nodes of foreign economic relations and contacts, main areas of new territories development, the most important links in the internal infrastructure, etc. It is urban agglomerations that should act as a kind of special platform of integration processes, on the basis of which the Republic of Kazakhstan should revive its historical role in the development of the global project "New Silk Road" and become a major trade and logistics, finance and business, innovation and technology, and tourism hub of the Central Asia region, a bridge between Europe and Asia.展开更多
