Niemcy, Rosja i kwestia polska w publicystyce Jędrzeja Giertycha na łamach "Horyzontów" paryskich (1956-1971)
2017
The liberalization of the communist system in mid-1950s, disillusionment with the policy of the West, fears connected with West German revisionism, and dwindling chances of change in the situation of Central-Eastern Europe contributed to a differentiation of attitudes among the Polish emigrants. Some of them, notably the nationalists, voiced the need to seek compromise with Russia. This led to the emergence of a pro-Russian option alongside the still dominant pro-Western one. The thesis on the need of an alliance with Russia was propagated by Jędrzej Giertych in his jo umalism in the "Horyzonty” monthly published in Paris. This ideologically committed opponent of communism and a staunch Cat…
Przyczynek do kwestii estetycznej około roku 1897
2017
A ąuestionnaire on “the essence and goal of a novel” published in 1897 in “Kurier Niedzielny” is an interesting documentation of aesthetic views of writers and literary critics in the late 19th century. Representatives of all literary generations of that time - from pre-positivists through two generations of Polish positivists to Young Poland writers - speak in favor of moderate aestheticism protesting against bias in literaturę and defend the autonomy of an artist. Quotes from participants exhibit good command of both idealistic (post-Hegel) aesthetic tradition and emotionalistic concepts of Positivism. They also foreshadow aesthetic predilection of Modemism. They do not provide an in-dept…
Veselīga uztura „šķīvja principa” maltīšu ietekme uz ķermeņa miesas būvi raksturojošiem antropometriskiem parametriem
2021
“Šķīvja princips” tiek uzskatīts par vienu no labākajiem veidiem, kā izglītot sabiedrību par veselīga uztura pamatprincipiem (Harvard University, 2011), nodrošinot organismu ar visām nepieciešamajām uzturvielām, minerālvielām un vitamīniem. Veselīga uztura “šķīvja princips” tiek plaši pielietots un ieteikts daudzu valstu, arī Latvijas Republikas Veselības ministrijas veselīga uztura rekomendācijās. Tomēr ir vērojams zinātnisko datu un pamatojuma trūkums “šķīvja principa” atbilstības novērtējumam uztura vadlīnijām. Tādēļ šī pētījuma mērķis ir novērtēt antropometrisko parametru izmaiņas paaugstinātas augu izcelsmes produktu diētas sešu nedēļu ievērošanas rezultātā pētījuma dalībniekiem ar atš…
Józef Wacław Dąbrowski (1797–1862). Wołynianin w armii Królestwa Polskiego
2021
W artykule, w oparciu o nieznane i tym samym niewykorzystywane dotąd przez historyków wspomnienia, przedstawione zostały dzieciństwo i młodość Józefa Wacława Dąbrowskiego, oficera wojska Królestwa Polskiego, dowódcę w randze kapitana i majora oddziałów powstańczych jesienią 1830 – latem 1831 r. Koleje jego losów i kariera wojskowa są tak typowe, jak i odbiegające od znanych i omawianych w literaturze przedmiotu schematów. Typowe, gdyż dzięki wywodzeniu się z kręgów średnio zamożnego ziemiaństwa rozpoczął służbę wojskową od stopnia kadeta, aby przed upływem roku awansować na podchorążego i uzyskać skierowanie do szkoły podchorążych, stanowiącej niezbędny etap służby potrzebny do awansu ofice…

A study of the optical effect of plasma sheath in a negative ion source using IBSIMU code
2020
A plasma sheath inside an ion source has a strong focusing effect on the formation of an ion beam from the plasma. Properties of the beam depend on the shape and location of the plasma sheath inside the source. The most accessible experimental data dependent on the plasma sheath are the beam phase space distribution. Variation of beam emittance is a reflection of the properties of the plasma sheath, with minimum emittance for the optimal shape of the plasma sheath. The location and shape of the plasma sheath are governed by complex physics and can be understood by simulations using plasma models in particle tracking codes like IBSimu. In the current study, a model of the D-Pace’s TRIUMF lic…
Electromagnetic and Thermal Modelling for Calculating Ageing Rate of Distribution Transformers
2018
Prediction of the lifetime for transformers is very important for maintenance and asset management. Finite element analysis was performed on a 5 MVA distribution transformers with aluminium foil-type windings and voltage rating 6600 V/23000 V. Electromagnetic modelling is implemented on the full three-phase transformer to calculate distributed losses, taking the skin effect into account. To reduce the computational burden, the distributed losses in one phase are used to analyse temperature rise in one phase of the transformer. The temperature rise results were used to determine the ageing rate of the transformer. Further, the influence of ambient temperature and cooling on the temperature r…
The challenge in realizing an exchange coupled BiFeO3-double perovskite bilayer
2020
Abstract In this work we propose a device design for efficient voltage control of magnetism. The magnetization of a ferrimagnetic double perovskite may be manipulated by an exchange coupled layer of multiferroic BiFeO3. Bilayers of Barium doped BiFeO3 and ferrimagnetic double perovskite Sr2FeMoO6 have been prepared by pulsed laser deposition motivated by the possibility of strong interlayer exchange coupling. While single layers of each material show high quality we observe that in both stacking orders the first layer decomposes during the deposition of the second layer. The reason for the decomposition are strongly differing growth conditions for BiFeO3 and Sr2FeMoO6. This means that the g…
A new 18 GHz room temperature electron cyclotron resonance ion source for highly charged ion beams
2020
An innovative 18 GHz HIISI (Heavy Ion Ion Source Injector) room temperature Electron Cyclotron Resonance (ECR) ion source (ECRIS) has been designed and constructed at the Department of Physics, University of Jyväskylä (JYFL), for the nuclear physics program of the JYFL Accelerator Laboratory. The primary objective of HIISI is to increase the intensities of medium charge states (M/Q ≅ 5) by a factor of 10 in comparison with the JYFL 14 GHz ECRIS and to increase the maximum usable xenon charge state from 35+ to 44+ to serve the space electronics irradiation testing program. HIISI is equipped with a refrigerated permanent magnet hexapole and a noncylindrical plasma chamber to achieve very stro…
