- (Contens №3 2020)
- ... Originality. It was shown for the first time that the “hanging” of the bit over the central part of the face is caused by the redistribution of axial load along the bit blades from the minimum value at the periphery of the blades to its sharp increase to the bit axis to compensate for the decrease in the path travelled by the bit in this zone. For the first time, it was proposed to perform blade bits with sharpened blades along a radius, and to destroy the resulting core with a special device. ...

- 2. Innovation development of transition countries in the context of their participation in global value chains
- (Contens №2 2020)
- ... Findings. It has been revealed that in the “core” countries, the economic growth is largely determined by investment in innovations, while for transition economies this dependence is much weaker. On the one hand, some of the transition countries (including Ukraine) have inefficient national innovation systems with low returns on R&D investments, and, on the other hand, some countries, that have experienced post-socialist transformation and joined the European Union, demonstrate relative economic success based on imported technologies brought up by the transnational capital. The vast majority of such countries has a low share of domestic value added in exports, while the EU “core”, which occupies higher positions in global value chains, on the contrary, shows a high share of domestic value added in exports, a significant share of high-tech exports in gross exports, along with higher GDP per capita. ...
