Identifying basic theoretical schemas (as images of real reality) with ideological doctrines (as subjective images of reality) has always been fraught with many dangers, and has often led to catastrophic consequences, sometimes visible to the naked eye. The post socialist transition is a good example of this claim. The subject of this paper is to e...

 The aim of this paper is to highlight the possibility of interpreting some recent mathematical theories without formulas. First, we will describe these mathematical theories (linear and metric spaces, affine transformations, and groups of transformations) via formulas in the language of modern mathematics. We will then explain these topics wi...

 In this work were synthesized hybrid materials based on aliphatic polyurethanes and small amounts of titanium dioxide nanoparticles (0.5; 2.0 and 3.0 wt.%). From an environmental point of view, this synthesized hybrid materials are significant engineering materials because the products of their thermal degradation are significantly less toxic...

 When designing machines that contain dynamic components, it is necessary to consider the tribological properties of the materials used for the functional parts of these components. The movement itself during the operation of the machines has a mechanical impact on these parts, which may result in the performance of the mechanism being affecte...
