Opis:
This text contains initial reflections on the subject of the academic biography of Norbert Elias from the perspective of the theory of ritual interactions. The author outlines the spatial-temporal conditions that produced the emotional energy in Elias’s works and to a large degree determined his great popularity in the second half of the 20th century and now.

Opis:
In modern clinical practice in various areas of dentistry, there is a need to virtualize and determine the diagnostic parameters of the stomatognathic system (SS). The aim of this article is to provide an evaluation of correct SS structures based on a comparison of mappings in pantomography, lateral cephalometry, and volumetric tomography using bone and tooth anthropometric points. The digital measurements performed determine the applicability of the analyzed imaging techniques for clinical diagnostics by indicating discrepancies and errors in the evaluation of geometric parameters. They should verify the location of characteristic points, lines, angles, and planes in relation to spatial objects mapped on the 1:1 scale. The analyses performed confirm the appearance of bone and dental structure asymmetry in healthy patients.

Opis:
The aim of this work was to characterize the changes in microstructure and chemical composition of the austenitic overlays on a pressure vessel steel that occur in the vicinity of the interface between the overlay and the base material. The investigations were carried out on a 16Mo3 boiler pipes weld overlaid by 309 and 310 steels. The microstructural examinations were performed on longitudinal cross-sectioned samples. The qualitative and quantitative chemical composition analyses on metallographic samples were determined on Scanning Electron Microscopy (SEM) by means of Energy Dispersive Spectrometry (EDS). The article analyzes the influence of the solidification sequence in both types of steel on final microstructure.

Opis:
The effect of 0.2% addition of Mg, Co and Ce to 99.9% cast aluminium was studied by evaluation of changes in microstructure and mechanical properties. The microstructure was analyzed by scanning electron microscopy and transmission electron microscopy. The Al99.9 alloy contained only Al-Fe-Si phase particles. Similar Al-Fe-Si particles were observed in alloy with 0.2% Mg addition, because this amount of magnesium was fully dissolved in the solid solution. The addition of cobalt resulted in the formation of Al9.02Co1.51Fe0.47 phase particles assuming the shape of eutectic plates. The electron backscattered diffraction map made for the alloy with 0.2% Co addition showed numerous twin boundaries with distances between them in the range from 10 to 100 µm. The addition of cerium was located in the grain boundary area. Cerium also gave rise to the formation of two types of particles, i.e. Al4Ce and Al-Ce-Fe-Si. The Al-Ce-Fe-Si phase is a nucleation site for the Al4Ce phase, which forms eutectic plates. The results showed that the introduction of additives increases the mechanical properties of the cast materials. The 99.9% cast aluminium has a hardness of 16.9 HB. The addition of 0.2% by weight of Mg, Co, Ce increases this hardness to 21.8 HB, 22.6 HB and 19.1 HB, respectively.
