Abstract Efficiency improvement in wind conversion field is the most critical scientific-and-technical problem, which is chiefly settled by increasing the power of wind turbines. A new technique was pioneered for determining the efficiency of wind turbines operation in the wind conditions of the Northern Black Sea region of Ukraine. It is found out that the main parameters that have an impact on the cost of electricity are as follows: the cost of a wind turbine itself and annual electric energy production. The cost indicators of wind turbines of the Ukrainian wind farms were defined in the wind conditions of the Northern Black Sea region in 2018, according to which it was ascertained that the cost of electric energy generated in Ukraine was by 17 % cheaper as compared to the world cost value. In illustration of application of the first ever developed technique, we have made the assessment of effective operation of the Ukrainian wind farms in the years of 2019 – 2020. The results obtained bear compelling evidence as to the correlations between the cost of produced electric energy and the size of wind turbines. In view of the above, application of wind turbines of super-large sizes in the conditions of the Northern Black Sea area of Ukraine (as well as in other regions of the world) is hardly expedient due to increase in the cost of electric power generated by them.

<p>The article presents data on the species diversity, the number of birds, directions and altitudes of flight during the periods of seasonal migrations based on studies of 13 wind farms in the Ukrainian Azov-Black Sea region. In total 194 expedition field trips have been performed for 549 days. There are 3 wind farms in the Black Sea basin, 7 in the Sivash-Dzharylgach basin and 3 in the Azov basin. We registered 100 bird species, but they use the territory of wind farms in different ways: they always present, periodically fly or do not fly to the wind farm. A large number of wetlands located in the Azov-Black Sea region attract waterfowl bird species that dominated (79.8% of the total number in spring and 68.7% in autumn). The analysis of the birds stay at the wind farm sites shows that there were registered not more than 25% of the total number of birds recorded in the study area. The main flight directions were north-east in spring (23.7% of all flights) and south-west in autumn (29.6%). Flying birds were registered at different altitudes, but 89.5% of birds flew in the range up to 50 m above the ground in spring and 79.1% – in autumn. The threats of wind farms on birds was evaluated by integrated management assessment tolls. It was found that just few of birds (about of 1 percent) could fly at dangerous altitudes (45-155 m) over the wind farm areas and cross the wind farm barrier. This wind turbines’ impact on the birds was considered as rather insignificant. The bird deaths caused by collisions with the wind turbines were not registered.</p>

Basing on a constructivist approach to international relations and foreign policy, the author has defined the conceptual content of the script, in which the experts of the Ukrainian National Institute for Strategic Studies imagine Crimea and the Black Sea region. The study was carried out on the basis of the materials of the Institute's analytical reports to the messages of the President to the Verkhovna Rada of Ukraine in 2014-2018. It was found that the ideas about Crimea contained in them are extremely mythologized: in the political picture of the world of the Institute's experts, the peninsula is considered as a “Russian bridgehead”, a source of “military threat" and an "occupied territory". Ukrainian experts are convinced that the motives of Russia's foreign and defense policy in the Black Sea direction are allegedly due to its desire for "expansion", "imperial policy" and the desire to "restore the Soviet Union." They perceive the reunification of Crimea with Russia as an event that led to a cardinal transformation of the geopolitical space of the Black Sea region that contradicts Ukrainian national interests. At the same time, on rational grounds, the institute is actively searching for conceptual approaches to organizing a new regional security system and creating a long-term, broad and durable alliance of anti-Russian forces, which could act as a NATO parallel structure in the Black Sea region in the future. Moreover, Ukrainian experts do not have any own geopolitical project or idea on this. They are considering several options for regional coalitions at once, paying special attention to the Polish concept of "Intermarium", which consists in creating a block of Baltic-Black Sea states.

In the recent history of the world, especially in the last two decades, large-scale military actions by Russia and Russian intervention have attracted wide international attention. Russia's increasingly confrontational stance has been manifested in military interventions in Georgia (2008) and in Ukraine (2014). The occupation/annexation of the territories of Georgia and Ukraine by the Russian Federation is a gross violation of the principle of sovereignty and territorial integrity of a country, as well as of the norms and principles of international law, that have significantly changed the international order established between the states and called into question the security of the Black Sea region and Europe as a whole. The purpose of this chapter is to provide a legal analysis of Russia's aggressive policy and the economic consequences of Ukraine and Georgia as aggrieved parties.

Abstract Energy production by wind turbines has many advantages. The wind is a renewable energy that does not emit greenhouse gases and has caused a considerable increase in wind farms around the world. However, this type of energy is not completely free of impact. In particular, wind turbines displace and kill a wide variety of wild species what forces us to plan their location well. In any case, the determination of the effects of wind farms on fauna, especially the flying one, is difficult to determine and depends on several factors. In this work, we will try to establish a mathematical algorithm that allows us to combine all variables that affect the species with the idea of quantifying the effect that can cause the installation of a wind farm with certain characteristics in a given place. We have considered specific parameters of wind farms, the most relevant environmental characteristics related to the location of the wind farm, and morphological, ethological and legal characteristics in the species. Two types of assessment are established for the definitive valuation. Total Assessment and Weighted Assessment. Total Valuation is established based on a reference scale that will allow us to establish categories of affection for the different species while Weighted valuation allows us to establish which species are most affected.

Murder Weapon

The article compares the plots of the Ossetian Nart epic (the tale of Axsar and Axsartag, sons of Warxag, in which one of the brothers gets killed by a doubled or forked arrow due to a misunderstanding) and the Icelandic epic (the story of the accidental murder of Baldr by his blind brother Höd with a dart from a mistletoe shoot, in medieval illustrations to which the murder weapon is also depicted as forked sprout). The peculiarity of the plot (a strange, forked murder weapon), which was already incomprehensible to Ossetian storytellers and Icelandic medieval writers, is a typical example of “common oddity,” which can be a decisive argument when comparing folklore motifs for a common origin. In addition to the similarity of the plots, a commonality is found in the genealogy of the heroes of these legends, through which they fit into the mythological picture of the world of the corresponding traditions and in the mythological onomasticon: the parallelism of pairs Odin — Frigg / Freya (with her father Njord, the god of waters) and Warхag / Wastyrdg’i — Dzerassa (daughter of the god of waters Donbettyr), semantic similarities in the names of the heroes (‘Warrior,’ ‘Hero’) and the exact match in the names of their ancestors (Boræ — Buri, Bor). All these observations allow us to hypothesize for the presence of borrowed Gothic plots in the North German epic tradition, which also include the story of Hermanarich, Sunilda and her brothers, known from Jordanes’ Getica. It also leads us to explain why some sagas trace the location of the Ases and Odin ancestral home to the mouth of the Don. These German-Ossetian parallels do not go back to Indo-European antiquity but testify to the close Gothic–Alanic contacts in the northern Black Sea region in the 3rd–4th centuries.

The main objective of this work was to evaluate the nearshore wind resources in the Black Sea area by using a high resolution wind database (ERA-Interim). A subsequent objective was to estimate what type of wind turbines and wind farm configurations would be more suitable for this coastal environment. A more comprehensive picture of these resources was provided by including some satellite measurements, which were also used to assess the wind conditions in the vicinity of some already operating European wind projects. Based on the results of the present work, it seems that the Crimea Peninsula has the best wind resources. However, considering the current geopolitical situation, it seems that the sites on the western part of this basin (Romania and Bulgaria) would represent more viable locations for developing offshore wind projects. Since there are currently no operational wind projects in this marine area, some possible configurations for the future wind farms are proposed.

In the article geopolitical strategy of North Atlantic Treaty Organization in the Black Sea pool is examined. An author examines instruments and mechanisms of policy of NATO. The special attention is spared the problem of increase of military-strategic pressure from the side of evroatlantic structures. The «ukrainian», «georgian», «romanian», «turkish» factors is examined in the article.Attempts from the side of NATO to use these factors for strengthening of pressure on opponents having no prospects and do damage international relations. Interests of policy of neighbourliness suffer. Thus expressing interests of transnational soldiery, financial and industrial structures, the USA and their allies intrude in other civilization and politic space.An author comes to the conclusion, that experience of the last decade testifies with all evidence about strategic absence of any prospect of attempts of the use of the Black Sea area as a buffer area of isolation and inhibition of Russia. Exactly after the foreign-policy going of Russian diplomacy near development of the Black Sea region is the future.Changing of accents from a geopolitical rivalry and fight for the «spheres of influence» to mutually beneficial partnership and clear distributing of mutual spheres of responsibility for maintenance of international stability opens on principle new prospects and for a wide collaboration in the field of ecology, rational use of natural resources, development of rekreacionnoy infrastructure.
