Pull environment of migration in the EU countries: Migration vector from Ukraine [PDF]

open access: yesProblems and Perspectives in Management, 2021
The growing Ukrainian migration towards EU countries determines the need for evaluation of pull factors shaping their environment to regulate these processes better. The study aims to assess the EU’s pull environment attracting migrants, and evaluate the

Comparison of the shear behavior in graphite-epoxy composites evaluated by means of biaxial test and off-axis tension test

open access: yesScience and Engineering of Composite Materials, 2021
Characterization of shear behavior in composite materials remains a not fully solved problem. In the last fifty years, many different approaches have been proposed to solve this problem (rail shear, thin-walled tube torsion, off-axis tensile, ±45 ...

A Minimalistic Prediction Model to Determine Energy Production and Costs of Offshore Wind Farms

open access: yesEnergies, 2021
A numerical framework for determining the available wind power and associated costs related to the development of large-scale offshore wind farms is presented. The idea is to develop a fast and robust minimal prediction model, which with a limited number

Investigation of the floating IEA Wind 15 MW RWT using vortex methods Part I: Flow regimes and wake recovery

open access: yesWind Energy, 2022
Floating wind turbines have the potential to enable global exploitation of offshore wind energy, but there is a need to further understand the complex aerodynamic phenomena they can encounter due to floater induced rotor motion.

Elasticity of the Achilles Tendon in Individuals With and Without Plantar Fasciitis: A Shear Wave Elastography Study

open access: yesFrontiers in Physiology, 2021
The elastic properties of the Achilles tendon (AT) are altered in local injury or other diseases and in response to changes in mechanical load. Recently, elastography has been used to evaluate variations in tendon elastic properties, mainly among healthy

Tensors in Newtonian Physics and the Foundations of Classical Continuum Mechanics

open access: yesMathematical and Computational Applications, 2019
In the Newtonian approach to mechanics, the concepts of objective tensors of various ranks and types are introduced. The tough classification of objective tensors is given, including tensors of material and spatial types. The diagrams are constructed for
