The 48f oxygen position parameter x, cohesive energy, bond type and defect-formation energy are discussed. The results show that parameter x can be used to indicate the disordering tendencies within a given pyrochlore family. Bond type, cohesive energy and defect-formation energies can be used to explain some experimental observations, but they are not determined exclusively by radiation ＂resistance＂ for a different pyrochlore family.展开更多

The problems of agriculture protection in the developed countries, for example in the EU and USA and also in the developing countries, were becoming serious obstacles during the negotiations. Despite the undeniable benefits of the multilateral WTO forum for trade liberalization, the rapid increase of North-South bilateral and multilateral free trade areas （FTAs） begs a systematic explanation for why some forums are prioritized relative to others. The main aim of the article is the presentation of some new aspects of the international business theory in the context of international economy. The article presents the mercantilist tendencies in the international trade policy, the theory of public choice in the foreign trade policy, protectionist pressures in different political systems, the level of protectionist pressures, food producers＇ pressure, and conflicts between the tendencies to sustainable international trade liberalization and environmental protection.展开更多
