Zasłużeni dla miasta. O mikrosystemie plateonimicznym Opola

2016

The Opole urban nomenclature has for many years been a space of special homage paid to the local heroes. Taking into account this fact, in my research I have concentrated on Opole streets, squares, buildings and estates named aftcr persons associated with this region. The analysis covered not only outstanding historical personalities, bul also contemporary authorities - writers, politicians and scientists. The purpose of this paper was to present the most important nomenclature trends associated with the regional history and to show the impact of names commemorating prominent historical figurcs on the contemporary image of Opole. This urban nomenclature microsystem eonsisting of about one h…

Âzyk do Kieva dovedët: âzykovaâ kommunikaciâ v oblasti turizma

2008

The paper covers the issues related to the intercultural communication in the area of tourism. The problems of linguistic communication are considered from the point of view of the adequacy of the translation of texts or statements related to the promotion of a country, a region, a place and a tourist objects into Russian or German. Historical information included in the texts of tourist guides appears to be an important matter in this area, because in the historiography of particular linguistic and cultural areas of language, there are noticeable differences in perception and interpretation of some historical facts. A notable issue is the adeąuacy of the translation of proper names relatin…

Numerical Simulations of the Flow Field of a Submerged Hydraulic Jump over Triangular Macroroughnesses

2021

The submerged hydraulic jump is a sudden change from the supercritical to subcritical flow, specified by strong turbulence, air entrainment and energy loss. Despite recent studies, hydraulic jump characteristics in smooth and rough beds, the turbulence, the mean velocity and the flow patterns in the cavity region of a submerged hydraulic jump in the rough beds, especially in the case of triangular macroroughnesses, are not completely understood. The objective of this paper was to numerically investigate via the FLOW-3D model the effects of triangular macroroughnesses on the characteristics of submerged jump, including the longitudinal profile of streamlines, flow patterns in the cavity regi…

Vertex corrections for positive-definite spectral functions of simple metals

2016

We present a systematic study of vertex corrections in the homogeneous electron gas at metallic densities. The vertex diagrams are built using a recently proposed positive-definite diagrammatic expansion for the spectral function. The vertex function not only provides corrections to the well known plasmon and particle-hole scatterings, but also gives rise to new physical processes such as generation of two plasmon excitations or the decay of the one-particle state into a two-particles-one-hole state. By an efficient Monte Carlo momentum integration we are able to show that the additional scattering channels are responsible for the bandwidth reduction observed in photoemission experiments on…

High-Reynolds-number turbulent cavity flow using the lattice Boltzmann method

2018

We present a boundary condition scheme for the lattice Boltzmann method that has significantly improved stability for modeling turbulent flows while maintaining excellent parallel scalability. Simulations of a three-dimensional lid-driven cavity flow are found to be stable up to the unprecedented Reynolds number $\mathrm{Re}=5\ifmmode\times\else\texttimes\fi{}{10}^{4}$ for this setup. Excellent agreement with energy balance equations, computational and experimental results are shown. We quantify rises in the production of turbulence and turbulent drag, and determine peak locations of turbulent production.

Lipid Binding Controls Dimerization of the Coat Protein p24 Transmembrane Helix

2019

Abstract Coat protein (COP) I and COP II complexes are involved in the transport of proteins between the endoplasmic reticulum and the Golgi apparatus in eukaryotic cells. The formation of COP I/II complexes at membrane surfaces is an early step in vesicle formation and is mastered by p24, a type I transmembrane protein. Oligomerization of p24 monomers was suggested to be mediated and/or stabilized via interactions within the transmembrane domain, and the p24 transmembrane helix appears to selectively bind a single sphingomyelin C18:0 molecule. Furthermore, a potential cholesterol-binding sequence has also been predicted in the p24 transmembrane domain. Thus, sphingomyelin and/or cholestero…

Few-body insights of multiquark exotic hadrons

2018

In this contribution we discuss the adequate treatment of the $4-$ and $5-$body dynamics within a constituent quark framework. We stress that the variational and Born-Oppenheimer approximations give energies rather close to the exact ones, while the diquark approximation might be rather misleading. Hall-Post inequalities provide very useful lower bounds that exclude possible stable states for some mass ratios and color wave functions.

Zur Semantik und Wortbildung der Personenbezeichnungen im oberschlesischen Deutsch

2020

Similar to various other diatopic varieties of German language, one finds numerous person names in Upper Silesian German, in which all possible qualities and modes of existence of the human being are focused and expressed. In the article attention is drawn once to the semantic classes oc-curring here, as well as to the types of nomination activated in the formation of the names, and then to the word formation types and the languages from which the morphemes forming the names were derived.

Statistical Approximation of Fourier Transform-IR Spectroscopy Data for Zinc White Pigment from Twentieth-Century Russian Paintings

2017

We present a statistical model for approximation of experimental Fourier transform-IR spectroscopy (FTIR) data for paint samples from paintings of different ages. The model utilizes random variations in some parameters (initial ageing rate, degree of change in ageing rate and time at which the change occurs). We determine the parameters characterizing variation in the paint composition and the storage conditions for the paintings. The numerical calculation is qualitatively consistent with the experimental data. In the proposed model, changes in the initial composition of the paint and the storage conditions make about the same contribution to the experimentally observed scatter in the data …
