Self-organization in the A + B → 0 reaction of charged particles
1992
The formalism of many-particle densities developed earlier by the authors is applied to the study of the self-organization phenomena occuring during the course of the bimolecular A + B → 0 reaction between charged particles, interacting via the Coulomb law. Unlike the Debye-Huckel theory, charge screening has an essentially non-equilibrium character. It is shown that for the asymmetric mobility of reactants (DA = 0, DB ≠ 0) similar immobile reactants A form aggregates characterized by a sharp maximum, observed at short distances, in the joint correlation function XA(r, t). Such an aggregation leads to the accelerated particle recombination n ∝ t-54 (nA = nB = n) instead of the generally acc…
Edukacja artystyczna na Ukrainie w kontekście dynamicznych zmian współczesnej cywilizacji
2015
W artykule analizuje się rozwój edukacji artystycznej w obrębie noosferogenezy. Uzasadniono znaczenie orientacji noosferycznej całego systemu edukacji artystycznej polegającej na formowaniu świadomości opartej na wiedzy noosferycznej i światopoglądzie noosferycznym. Osiągnięcie integracji edukacji artystycznej ze współczesnym globalnym światem informacyjnym wymaga włą- czenia przyszłych nauczycieli dyscyplin artystycznych w metasystem działalności artystyczno-pedagogicznej, który mimo swej dynamiczności posiada pewną strukturę i organizację, pozwala orientować się w procesie samorozwoju, dodając mu własne ukierunkowanie.

Copper( ii ) complexes with phosphorylated 1,10-phenanthrolines: from molecules to infinite supramolecular arrays
2016
International audience; The reaction of phosphorylated 1,10-phenanthrolines 3-Pphen, 3,8-Pphen and 4,7-Pphen (3-Pphen = 3-diethoxyphosphorylphenanthroline, 3,8-Pphen = 3,8-bis(diethoxyphosphoryl) phenanthroline, 4,7-Pphen = 4,7-bis(diethoxyphosphoryl) phenanthroline) and hydrated copper(II) nitrate in a 1 : 1 ratio leads to the formation of supramolecular architectures. In the 1D coordination polymer [Cu(3-Pphen)(NO3)(2)](n) (2) the copper atom is coordinated to only one phenanthroline ligand and the coordination sphere is completed by two oxygen atoms of nitrate anions and the oxygen atom of the phosphoryl group from the neighbouring phenanthroline ligand. Complex Cu(3,8-Pphen)(NO3)(2) (3)…
3D nanoscale ordered architectures in thin films for organic electronics
2011
Order in molecular thin films is of fundamental importance to gain and exploit a series of properties in nanotechnology. In this contest, engineering 2D supramolecular and molecular superstructures is of particular interest. They offer great possibilities for several applications whose achievement also allows for new theoretical approaches and nanoscale laws [1]. A natural extension of 2D nanopatterning concerns the attainment of a 3D nanoscale control in molecular films [2]. This question is complex to challenge and it is of ultimate importance in emerging fields like organic and hybrid photovoltaics, organic thin film transistors and sensors as well as plastic electronics. For example, th…
Self in NARS, an AGI System
2018
This article describes and discusses the self-related mechanisms of a general-purpose intelligent system, NARS. This system is designed to be adaptive and to work with insufficient knowledge and resources. The system’s various cognitive functions are uniformly carried out by a central reasoning-learning process following a “non-axiomatic” logic. This logic captures the regularities of human empirical reasoning, where all beliefs are revisable according to evidence, and the meaning of concepts are grounded in the system’s experience. NARS perceives its internal environment basically in the same way as how it perceives its external environment although the sensors involved are completely diff…
Changes in farmers’ participation in rural Organizations of Opolszczyzna Region
2016
W artykule podjęto próbę określenia zmian w zakresie samoorganizacji społeczności wiejskiej Opolszczyzny z uwzględnieniem konstruktu kapitału społecznego. W tym celu wykorzystano dane uzyskane od osób kierujących gospodarstwami rolnymi zamieszkałych w wybranych gminach Opolszczyzny. Zostały one zebrane za pomocą kwestionariusza wywiadu. Zawarte w nim pozycje umożliwiły określenie zmian, jakie zaszły w latach 2008–2014, m.in. pod względem: przynależności respondentów do różnych organizacji samorządu wiejskiego, sposobu postrzegania przez rolników efektów działań tych instytucji czy postrzegania przez kierowników gospodarstw rolnych możliwości wywierania wpływu przez różne podmioty na sytuacj…
Simple Rules for Complex Near-Glass-Transition Phenomena in Medium-Sized Schiff Bases
2022
Glass-forming ability is one of the most desired properties of organic compounds dedicated to optoelectronic applications. Therefore, finding general structure–property relationships and other rules governing vitrification and related near-glass-transition phenomena is a burning issue for numerous compound families, such as Schiff bases. Hence, we employ differential scanning calorimetry, broadband dielectric spectroscopy, X-ray diffraction and quantum density functional theory calculations to investigate near-glass-transition phenomena, as well as ambient- and high-pressure molecular dynamics for two structurally related Schiff bases belonging to the family of glycine imino esters. Firstly…
Hexagonal Microparticles from Hierarchical Self-Organization of Chiral Trigonal Pd3L6 Macrotetracycles
2021
Construction of structurally complex architectures using inherently chiral, asymmetric, or multi-heterotopic ligands is a major challenge in metallosupramolecular chemistry. Moreover, the hierarchical self-organization of such complexes is unique. Here, we introduce a water-soluble, facially amphiphilic, amphoteric, chiral, asymmetric, and hetero-tritopic ligand derived from natural bile acid, ursodeoxycholic acid. We show that via the supramolecular transmetalation reaction, using nitrates of Cu(II) or Fe(III), and subsequently Pd(II), a superchiral Pd3L6 complex can be obtained. Even though several possible constitutional isomers of Pd3L6 could be formed, because of the ligand asymmetry a…
Developing a metatheoretical framework for second language development : a cultural-historical theory and dynamic systems theory perspective
2017
The main aim of this article-based dissertation is to construct and articulate a dialectical metatheoretical architecture for the study of second language development termed Purposive-Historical Systems Theory (PHiST) invoking, inter alia, the axiomatic imperatives of dynamic systems theory (DST), Vygotskian cultural-historical theory (CHT), and Pepperian root metaphor theory (RMT). Specifically, it primarily purports, first, to demonstrate the tenability of a dialectical synthesis of DST and CHT; second, to philosophize on the fundamental contours of PHiST; third, to apply a novel metatheoretical perspective, as a quintessential example, to reconceptualizing the seminal construct of the Zo…
