Andrzej Twardowski

Kultura i Edukacja > 2022 > 2(136) > 48-61

This article aims to describe the cultural model of disability. In contrast to the social model of disability, which is strongly coherent, the cultural model of disability has not yet been specified, despite ongoing discussions on cultural determinants of understanding disability. In the first part of the article, the origins and essence of the cultural model are presented. Next, the four main assumptions...

Nowa koncepcja wczesnego wspomagania rozwoju dzieci z niepełnosprawnościami

Andrzej Twardowski

Forum Pedagogiczne > 2014 > 4 > 1 > 15-33

Przedmiotem artykułu jest nowa koncepcja wczesnego wspomagania rozwoju dzieci z niepełnosprawnościami. Dopiero w ostatnim dwudziestoleciu tradycyjny paradygmat wczesnego wspomagania, skoncentrowany na specjalistach, został zastąpiony nowym, skoncentrowanym na rodzinie. Istota zmiany polegała na odejściu od oddziaływań prowadzonych bezpośrednio z niepełnosprawnym dzieckiem na rzecz współpracy z rodziną...

Nanopowders of gallium nitride GaN surface functionalized with manganese

Michał Musiał, Jacek Gosk, Andrzej Twardowski, Jerzy F. Janik, more

Journal of Materials Science > 2017 > 52 > 1 > 145-161

Four GaN nanopowders of systematically varying surface properties, prepared via an anaerobic synthesis method from gallium imide (ammonia assisted decomposition in the range 600–975 °C), were subjected to functionalization with manganese centers. Each powder was slurried in a diluted hexane solution of manganese (II) bis{bis[trimethylsilyl]amide} Mn{N[Si(CH₃)₃]₂}₂ and stirred overnight at ambient...

Tuning the bimetallic amide-imide precursor system to make paramagnetic GaMnN nanopowders

Mariusz Drygas, Jerzy F. Janik, Michal Musial, Jacek Gosk, more

Materials Chemistry and Physics > 2016 > 180 > C > 173-183

A bimetallic molecular system made of gallium (III) tris(dimethyl)amide Ga(NMe₂)₃ and manganese (II) bis(trimethylsilyl)amide Mn[N(SiMe₃)₂]₂ (Me = CH₃, fixed initial Mn-content 10 at.%) was subjected to ammonolysis in refluxing/liquid ammonia. Upon isolation at room temperature, the amide-imide mixed metal precursor was pyrolyzed at elevated temperatures under an ammonia flow by two different routes...

A precursor system made of Ga(NMe₂)₃ and Mn[N(SiMe₃)₂]₂ (Me=CH₃, initial Mn-contents 5, 10, 20at.%) upon ammonolysis in refluxing ammonia afforded Ga/Mn amide-imide precursors. The 10at.% Mn-precursor was nitrided at 500, 700, and 900°C. The 5 and 20at.% Mn-precursors were nitrided only at 900°C. All nanopowders were characterized by XRD, FT-IR, SEM/EDX, whereas some by Raman spectroscopy and XRF...

Ferromagnetic spins interaction in networked triarylamine polymers

Piotr Kurzep, Jacek B. Gosk, Ireneusz Wielgus, Andrzej Twardowski, more

Synthetic Metals > 2015 > 199 > Complete > 27-32

Two hyperbranched polymers containing star-shaped conjugated triarylamine units altered with meta-phenylene units were synthesized. The polymers can be oxidized on chemically or electrochemically to radical cations which are the sources of electronic spins. The presence of meta-phenylenes in the polymers chemical structures allows for the ferromagnetic coupling of electronic spins which leads to the...

Micromagnetic Study of Dipole-Field-Mediated Synchronization Between Domain Wall Spin Torque Nano-Oscillators

Konrad Dziatkowski, Andrzej Twardowski

IEEE Transactions on Magnetics > 2014 > 50 > 11 > 1 - 4

Spin torque nano-oscillators (STNOs) exhibiting low power of microwaves generated from a single device have to be bundled and phase-locked to achieve levels of emission that are satisfactory for applications. In this paper, dipolar coupling and synchronization in the ensembles of nanowire-shaped domain wall STNOs are investigated with the micromagnetic modeling method. The stray field interaction...

Interdyscyplinarne Konteksty Pedagogiki Specjalnej > 2014 > 5 > 17-39

Inclusion of able peers into the process of aiding the development of disabled children is beneficial for both groups. Able children have the opportunity to get to know disabled peers better, to understand them and to develop an accepting attitude toward them. Disabled children have the opportunity to learn that their able peers pay attention to them and are willing to play and talk to them. They...

Structural and magnetic properties of MnAs/GaAs ferromagnetic semiconductor nanocomposite material

Adam Kwiatkowski, Dariusz Wasik, Maria Kamińska, Jolanta Borysiuk, more

Journal of Materials Science: Materials in Electronics > 2008 > 19 > 8-9 > 740-743

Self-organized (Ga,Mn)As nanoclusters, embedded in GaAs and formed during thermal annealing of Ga_1-xMn_xAs layer at 500 °C or 600 °C, were studied using Transmission Electron Microscopy (TEM) and Magnetic Force Microscopy (MFM). We found that 10–20 nm large NiAs-type hexagonal MnAs nanocrystals gave magnetic contrast in MFM images, whereas smaller zinc-blende nanoinclusions were not visible by means...

Maria Kaminska, Andrzej Twardowski, Dariusz Wasik

Journal of Materials Science: Materials in Electronics > 2008 > 19 > 8-9 > 828-834

III–V semiconductors doped with magnetic ions have been attracting interest of many laboratories all over the world during more than thirty years. At the beginning the reason was the will to understand influence of omnipresent unintentional, as well as intentionally introduced, impurities of transition metals or rare earths on electrical and optical properties of semiconductors commonly applied in...
