BACKGROUND In the past decade, the countries that emerged from the Soviet Union have experienced major changes in the inherited Soviet model of health care, which was centrally planned and provided universal, free access to basic care. The underlying principle of universality remains, but coexists with new funding and delivery systems and growing out-of-pocket payments. OBJECTIVE To examine p...

The present article is dedicated to the generalization of data obtained in the framework of the preparation of Armenian portion of European Soil Database. Briefly described geography of Armenia. Great variability of soil variants represented in Armenia is recorded. It is shown that nearly all zonal soil types those are developed not only in the region of Little Caucasus and the Armenian Volcani...

Based on the GLOBE model global dynamic computable general equilibrium model (to describe functioning and interaction of the Customs Union (CU) of Belarus, Kazakhstan, and Russia with Armenia, Kyrgyzstan, the European Union and the rest of the world) is developed and calibrated. The calibrated model is tested for the possibility of practical application and on its base the possibility of optima...

The generalization of the Yang-Baxter equations (YBE) in the presence of Z2 grading along both chain and time directions is presented and an integrable model of t− J type with staggered disposition along a chain of shifts of the spectral parameter is constructed. The Hamiltonian of the model is computed in fermionic formulation. It involves three neighbour site interactions and therefore can be...
