RESEARCH OF POWER IMPULSES TRANSFER THROUGH THREADED CONNECTIONS OF THE DRILL-STRING DURING ROTARY-PERCUSSION DRILLING OF PILOT HOLES FOR TRENCHLESS PIPELINE LAYING

The relevance of the research.Pilot wells for horizontal directional drilling can be attributed to slim holes that are widely used in mining, in particular, for detailed exploration and underground development of non-ferrous metal ores, for degassing mine workings of coal mines, as well as in a lot of other industries to limit the diameter of Stimu

Due to its periodic porous structure and high mechanical strength, carbon honeycomb (CHC), a new carbon allotrope, possesses a high energy absorption capability and thus great potential for the design and fabrication of advanced impact-resistant materials.In this work, the propagation and attenuation of shock waves in CHC are investigated for the f

Providing cyber-resilient IoE systems has become the need of modern times.In particular, IoT Candles drones are prone to several cyber attacks while navigating in the air.Deliberate transmission of deceptive GPS signals targeted at commercial applications can misdirect global positioning system (GPS)-guided drones, causing them to deviate from thei

The article analyzes the provisions of the current criminal procedural legislation of Ukraine and separate scientific works in the field of criminal procedure regarding the detention of a person under suspicion of committing a criminal offense without a decision of the investigating judge or a court, especially when the detention of a person under

Honey bees are valuable bioindicators.As such, they hold a vast potential to help shed light on the extent and interdependencies of factors influencing the decline in the number of insects.However, to date this potential has not yet been fully leveraged, as the production of reliable data requires large-scale study designs, which are very labour in
