FORMATION OF THE COMMERCIAL INFRASTRUCTURE OF THE EURASIAN ECONOMIC UNION’S COMMON POWER MARKET
The commercial infrastructure formation is a key challenge of creating a common electric power market for the Eurasian Economic Union member states (Russia, Belarus, Kazakhstan, Kyrgyzstan and Armenia) provided for in the Treaty on the Eurasian Economic Union. The comparative analysis of electricity trading arrangements in the Eurasian Economic Union states have been presented in the article. It has been shown, that there are notable differences between combined power markets of these group of states in terms of the organization of trade relations (participants, infrastructure services, rules on trade and pricing policies). It has been established, that only the characteristics of the Russian electric power market fully comply with the requirements of program documents for the Eurasian Economic Union common electric power market. The appropriate recommendations on measures to adapt the power markets of other Eurasian Economic Union States to these requirements have been give

Trifluralin-induced disorganization of microtubular cytoskeleton alters the development of roots in Hordeum vulgare L.
The extensive use of herbicides in agriculture becomes an important factor in environmental pollution, especially in case of slowly degradable compounds. Some agents act on plants during a long period of time, even if a very low concentration of the herbicide remains in the soil. Here, we investigated the toxicological effect of a low concentration of dinitroaniline herbicide, trifluralin, on growing seedlings of
Hordeum vulgare
L. Trifluralin in concentration of 1 μg/ml inhibited root growth. The mitotic activity of meristematic cells was suppressed due to the retardation of metaphase progression — alteration that can be caused by cytoskeleton disorder. Using antibodies to α-tubulin, we investigated the distribution of microtubules in root meristem cells. During all stages of mitosis, the highly regular system of microtubular cytoskeleton observed in control cells was slightly disorganized. An examination of root structure using light and electron microscopy demonstrated that the cell walls did not form normally during cell division that led to the appearance of large multinucleated cells. Also, the premature (pathological) cell differentiation was induced by trifluralin. A part of differentiating cells showed intracellular structural changes that are consistent with programmed cell death. It seems that the development of alterations in trifluralin-treated roots was due to the microtubular cytoskeleton disorganization
