Youth activism in Poland: Perceptions, participation and diverging perspectives from young people and activists

British Educational Research Journal, EarlyView.
Abstract Recent years have seen a growing scholarly interest in youth activism (YA), a phenomenon often viewed as a positive development in response to declining civic and political engagement among young people. However, most of the research focuses on the activists themselves and gives less attention to how YA is perceived by the broader youth ...

Design of a Hydroelectronic Solar‐Tracking System for Solar Panels

Energy Science &Engineering, EarlyView.
A prototype of a passive solar‐tracking system utilizing buoyant force based on water level was developed, and its MATLAB/Simulink model was implemented. This study is expected to encourage researchers to design solar‐tracking mechanisms using metals with different thermal expansion coefficients, air, oil, and other fluids. ABSTRACT This study presents

Astrometry of Galactic Star Forming Region Sharpless 269 with VERA : Parallax Measurements and Constraint on Outer Rotation Curve

, 2007
We have performed high-precision astrometry of H2O maser sources in Galactic star forming region Sharpless 269 (S269) with VERA. We have successfully detected a trigonometric parallax of 189+/-8 micro-arcsec, corresponding to the source distance of 5.28 +
