Oppressive Faces of Whiteness in Walter Mosley’s "Devil in a Blue Dress"

2018

Walter Mosley’s Devil in a Blue Dress contributes significantly to the literary debate on the definition of whiteness. The socio-historical construction of whiteness emerging from the novel is amplified by white imagery dovetailing with the claims made about white people directly. For the African American first person narrator, Easy Rawlins, living in post-World War II Los Angeles, whiteness mostly spells terror. The oppressive faces of whiteness consist in the following trajectories: property relations, economic exploitation, labour relations, the legal system, different miens of oppressive white masculinity denigrating blackness, spatial dynamics of post-World War II Los Angeles and the w…

Modelling and analysing oriented fibrous structures

2014

Abstract. A mathematical model for fibrous structures using a direction dependent scaling law is presented. The orientation of fibrous nets (e.g. paper) is analysed with a method based on the curvelet transform. The curvelet-based orientation analysis has been tested successfully on real data from paper samples: the major directions of fibrefibre orientation can apparently be recovered. Similar results are achieved in tests on data simulated by the new model, allowing a comparison with ground truth. peerReviewed

Characterization of three-dimensional microstructure of composite materials by X-ray tomography

2016

Analysis methods for X-ray microtomographic images of short fibre composite materials were developed. The methods enable estimation of microstructural properties of the material, e.g., aspect ratio and orientation of fibres. Being based on X-ray microtomography and image analysis, the methods are nondestructive and do not require user intervention. In particular, a method for determination of the aspect ratio of fibres was first developed. The method contains an assumption about similarity of the shape of the fibres. The assumption was relaxed in an improved method that can estimate cross-sectional properties of fibres, too, e.g., cross-sectional area. Additionally, the effect of finite ima…

Piotr Ogrodzki (1958-2013)

2013

News about the death of Piotr Ogrodzki came so suddenly that it left us numb. A good and unique person passed away – a lawyer, an expert on historical monuments, a theoretician on securing works of art, a sensitive soul. His loss is irreparable. Having known Piotr for years as a modest person shying from acclaim I am aware that he would not have wanted to become the topic of written reminiscences. On the other hand, it is our duty to express gratitude to men of merit and pay homage in return for all that they did for us. In this way, we demonstrate our respect, admiration and appreciation. Piotr Ogrodzki never sought popularity. He performed tasks, which he regarded as his duty as best and …

Język metaforyczny w modelu Wrocławskiej Szkoły Przyszłości

2020

W niniejszym artykule poszukuję odpowiedzi na pytanie: Jakie są sensy i znaczenia metafor we Wrocławskiej Szkole Przyszłości (WSP)? Ukazuję zastosowanie języka metaforycznego w szkole, gdzie metaforę traktuje się jako źródło wiedzy o otaczającym świecie, jako swoiste wspomaganie efektywniejszej komunikacji oraz jako stymulator wyobraźni. We WSP uważa się, że dziecko nie musi być skazane na edukację opartą na stereotypowych zachowaniach. Uważa się tam, że w procesie edukacji potrzebne jest myślenie kreatywne, oparte na rozmaitych skojarzeniach, w których wykorzystywana jest umiejętność tworzenia mapy myśli, wyobraźni, czyli tzw. edukacja z wyobraźnią. Taką edukację we Wrocławskiej Szkole Prz…

The Large Observatory For x-ray Timing

2014

The Large Observatory For x-ray Timing (LOFT) was studied within ESA M3 Cosmic Vision framework and participated in the final down-selection for a launch slot in 2022-2024. Thanks to the unprecedented combination of effective area and spectral resolution of its main instrument, LOFT will study the behaviour of matter under extreme conditions, such as the strong gravitational field in the innermost regions of accretion flows close to black holes and neutron stars, and the supra-nuclear densities in the interior of neutron stars. The science payload is based on a Large Area Detector (LAD, 10 m 2 effective area, 2-30 keV, 240 eV spectral resolution, 1 deg collimated field of view) and a WideFi…

Excess electronic recoil events in XENON1T

2020

We report results from searches for new physics with low-energy electronic recoil data recorded with the XENON1T detector. With an exposure of 0.65 t-y and an unprecedentedly low background rate of $76\pm2$ events/(t y keV) between 1 and 30 keV, the data enables sensitive searches for solar axions, an enhanced neutrino magnetic moment, and bosonic dark matter. An excess over known backgrounds is observed at low energies and most prominent between 2 and 3 keV. The solar axion model has a 3.4$\sigma$ significance, and a 3D 90% confidence surface is reported for axion couplings to electrons, photons, and nucleons. This surface is inscribed in the cuboid defined by $g_{ae}<3.8 \times 10^{-12}$,…

Hydrogels for Three-Dimensional Ionizing-Radiation Dosimetry

2021

Radiation-sensitive gels are among the most recent and promising developments for radiation therapy (RT) dosimetry. RT dosimetry has the twofold goal of ensuring the quality of the treatment and the radiation protection of the patient. Benchmark dosimetry for acceptance testing and commissioning of RT systems is still based on ionization chambers. However, even the smallest chambers cannot resolve the steep dose gradients of up to 30–50% per mm generated with the most advanced techniques. While a multitude of systems based, e.g., on luminescence, silicon diodes and radiochromic materials have been developed, they do not allow the truly continuous 3D dose measurements offered by radiation-se…
