Smoleńska roszada 2010. Walka o wartości czy gry rzeczywistością

The study deals with the phenomenon of reality transformation by means of semantic modification and change of meanings of key concepts in narrative about the reality. It explains how political parties undertook such an attempt and the context of the transformation of this phenomenon as a result of the Smolensk plane crash and subsequent short-term replacement of before crash reality with a new reality constructed just after the event. Deals with relationship of Sapir-Whorf theory of Linguistic relativism with the concept of Social Construction of Reality by Berger and Luckman. The context of teoretical frame is the Jaroslaw Kaczynski’s presidential campaign of 2010 with the focus on key statements of the candidate and their changes over time. Concluding with the problem of disorder in the realities after the presidential elections and the consequences of which appeared to be completely different for the organization of the party than the general population.Tekst dotyczy problematyki zjawiska przemiany rzeczywistości za pomocą językowej manipulacji znaczeniami symboli i pojęć kluczowych dla narracji o rzeczywistości partii politycznych, w kontekście przemiany tego zjawiska na skutek katastrofy smoleńskiej i następującego po nim zjawiska krótkotrwałego zastąpienia rzeczywistości nową wytworzoną tuż po katastrofie. Przedstawia związek teorii relatywizmu językowego Sapira-Whorfa z koncepcją społecznego tworzenia rzeczywistości Bergera i Luckmana w kontekście próby uchwycenia kampanii prezydenckiej Jarosława Kaczyńskiego w paradygmacie konstruowania językowego rzeczywistości społecznej ze wskazaniem kluczowych wypowiedzi i ich zmiany w czasie, a także pozostawiony po wyborach bałagan w rzeczywistościach i jego konsekwencje, które ukazały się zupełnie inne dla organizacji partyjnych niż dla ogółu wyborców

Tests of the acoustic emission of the power steering column equipped with a modified composite worm gear housing

Paper presents results of the laboratory tests concerning with measurements of the acoustic emission of the power steering column equipped with a modified composite gear body juxtaposed with the production version of the power steering column with the gear body made of aluminium alloy. The new, developed power steering column worm gear housing is made of a polymer called polydicyclopentadiene (PDCPD) and the Reaction-Injection-Moulding technology was used to produce it (the shortcut of the technology name is RIM technology). Both types of the worm power steering housings were tested to analyse their properties of acoustic emission. Results of the tests are very important considering noise generated during exploitation of a car’s power steering system

A preliminary study of three-dimensional reconstruction of the human osseous labyrinth from micro-computed tomography scans

The adult human temporal bone was investigated using micro-CT scans. Various aspects of the osseous labyrinth were presented in figures which are effect of the volume rendering. The 3D reconstructions were performed to visualize the cochlea and the semicircular canals embedded in the petrous bone. The final product of this study was a digital three-dimensional model of the entire osseous labyrinth which can be viewed at different angles on the computer screen

Hydrogen bonding and infrared spectra of ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide/water mixtures : a view from molecular dynamics simulations

[Image: see text] Simulations of ab initio molecular dynamics have been performed for mixtures of ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIM-TFSI) ionic liquid and water. Statistics of donors and acceptors of hydrogen bonds has revealed that with increasing water content, hydrogen bonds between EMIM cations and TFSI anions are replaced by bonds to water molecules. In the mixture of liquids, the total number of bonds (from EMIM cations or water molecules) formed by TFSI acceptors increases. IR spectra obtained from ab initio molecular dynamics trajectories are in good agreement with literature data for ionic liquid/water systems. Analysis of oscillations of individual C–H and O–H bonds has shown correlations between vibrational frequencies and hydrogen bonds formed by an EMIM cation or water molecule and has indicated that the changes in the IR spectrum result from the decreased number of water–water hydrogen bonds in the mixture. The tests of DFTB methodology with tailored parameterizations have yielded reasonably good description of the IR spectrum of bulk water, whereas available parameterizations have failed in satisfactory reproduction of the IR spectrum of EMIM-TFSI/water mixtures in the region above 3000 cm(–1)

NaFSI and NaTFSI solutions in ether solvents from monoglyme to poly(ethylene oxide) : a molecular dynamics study

[Image: see text] Classical molecular dynamics simulations have been performed for a series of electrolytes based on sodium bis(fluorosulfonyl)imide or sodium bis(trifluoromethylsulfonyl)imide salts and monoglyme, tetraglyme, and poly(ethylene oxide) as solvents. Structural properties have been assessed through the analysis of coordination numbers and binding patterns. Residence times for Na–O interactions have been used to investigate the stability of solvation shells. Diffusion coefficients of ions and electrical conductivity of the electrolytes have been estimated from molecular dynamics trajectories. Contributions to the total conductivity have been analyzed in order to investigate the role of ion–ion correlations. It has been found that the anion–cation interactions are more probable in the systems with NaTFSI salts. Accordingly, the degree of correlations between ion motions is larger in NaTFSI-based electrolytes

Explicit and hybrid solvent models for estimates of parameters relevant to the reduction potential of ethylene carbonate

Using ethylene carbonate as a sample solvent, we investigated two molecular parameters used to estimate the reduction potential of the solvent: electron affinity, and the energy of the lowest unoccupied molecular orbital (LUMO). The results showed that the values of these parameters are inconsistent for a single ethylene carbonate molecule in vacuum calculations and in the continuous effective solvent. We performed a series of calculations employing explicit or hybrid (explicit/continuous) solvent models for aggregates of solvent molecules or solvated salt ions. In the hybrid solvent model, values of the two estimates extrapolated to an infinite system size converged to one common value, whereas the difference of 1 eV was calculated in the purely explicit solvent. The values of the gap between the highest occupied molecular orbital (HOMO) and the LUMO obtained in the hybrid model were significantly larger than those resulting from the explicit solvent calculations. We related these differences to the differences in frontier orbitals and changes of electron density obtained in the two solvent models. In the hybrid solvent model, the location of the additional electron in the reduced system usually corresponds to the LUMO orbital of the oxidized system. The presence of salt ions in the solvent affects the extrapolated values of the electron affinity and LUMO energy
