These indisputable facts does not change our view of the situation in which the EU is, or at major tasks whose managing can be considered as condition of its continued existence as an important part of the global economy. As the fundamental problem of the EU, persisting differences in economic level of the member states is considered. The aim of this paper is not to formulate and even to propose how the EU should look like in the future, but to assess criteria of decision making about concept of its future direction. In this context, the verification of argument will be performed, that only the integration of the countries that have common interests and objectives respectively are able to make the same efforts to meet them, is in certain stages of integration possible and functional. Conversely, a broader territorial structured integration of countries with significantly different economic parameters is feasible and functional only at lower stages of integration. This paper starts from that the process of economic convergence among member states as a condition for integration can be realized at the lower stage of the integration process, in terms of economic and monetary union, then only the expense of reducing the dynamics of economic development of integration group as a whole. Some degree of equilibrium of economic levels represents an important condition for the success of the integration project. To meet this goal, current differences in economic level of individual EU member states （comparative analysis using indicators of growth rate and development of GDP/capita） will be analyzed, including the assessment of the cost of the EU for the implementation of cohesion policy, both in terms of the economic crisis and the phase of requirement to the revival of the European economy. In this context, also the effectiveness of institutional arrangements of decision-making procedures will be assessed.展开更多

However, they have rarely been reported. In this work, a series of crystalline complexes of rare earth perchlorate coordinated with glutamic acid have been synthesized in water medium, and their thermodynamical data, including the heat capacity in low temperature range and the standard enthalpy of formation, were determined. These complexes were identified to be [RE2(Glu)2(H2O)8](ClO4)4·H2O (RE = Nd, Eu, Dy) by using thermogravimetric analysis (TG), differential thermal analysis (DTA), and chemical and elementary analyses. Their purity has been determined. No melting points were observed for all the three complexes. The heat capacity of the complexes was measured by an adiabatic calorimeter from 79 to 370 K. Abnormal heat capacity values were detected for two of the complexes and the decomposition range of one complex was found. The temperature, enthalpy change and entropy change of the decomposition processes of the three complexes were calculated. The polynomial equations of heat capacity in the experimental temperature range have been obtained by least squares fitting. The standard enthalpy of formation was determined by an isoperibol reaction calorimeter at 298.15 K.展开更多
