“…To measure the temperature dependences of IF Q −1 (Т) and elastic modulus E(T), resonance vibrations at frequency f ≈ 2 kHz and the methods of a complete piezoelectric oscillator at frequency f ≈ 117 kHz and during alternative deformation ε ≈ 10 −6 in vacuum P ≈ 10 −3 Pa were used. The measurement error of IF determination was ΔQ −1 /Q −1 ≈ 10%, and the relative change in the elastic modulus was ΔE/E ≈ 0.1% [17][18][19][20][21].…”

The simultaneous influence of hydrogen H and ultrasound deformation on internal friction Q −1 and dynamic elastic modulus E of intermetallic Ti3Al alloy after cutting and polishing were studied. The relaxation maximum of internal friction Q −1 M1 at temperature Т М1 ≈ 398 К, conditioned by the mechanism caused by reorientation interstitial atoms in dumbbell configurations H-H was discovered. Internal friction maximum Q −1 M2 in intermetallic Ti3Al at temperature T M2 ≈ 439 K was discovered with an activation energy H 2 = 0.86±0.1 eV. 2D and 3D atomic force microscopy microstructure images of Ti (VT8) alloy after mechanical and thermal treatment are presented. Strengthening of Ti alloys is related to the cooperation of dislocations with point defects.

Developing a predictive system for water deficit analysis in the Black Sea Lowland, especially in climate change, involves integrating various data sources, modeling techniques, and technological tools to forecast water availability and demand. The analysis of the change in moisture deficit in the Kherson region is provided for the period from 1955 to 2022. A description of temperature gradients across the Kherson region is provided. The distribution of precipitation throughout the years in terms of quantity and intensity is provided. As part of the Black Sea Lowland, the Kherson region is critically important for southern Ukraine's agriculture and water security. Given the region's reliance on irrigation and the challenges posed by climate change, developing a predictive system for water deficit analysis is essential. Such a system can help stakeholders make informed decisions to ensure sustainable water management and mitigate the adverse effects of water scarcity.
