Sudeckie linie życia. O "Grandhotelu" Jaroslava Rudiša
2012
Powieść Grandhotel to utwór czeskiego pisarza młodego pokolenia Jaroslava Rudiša. Portrety i losy bohaterów powieściowych zostały wpisane przez Rudiša w dwudziestowieczną historię Liberca i sudeckich okolic. Stworzenie postaci Fleischmana – głównego bohatera powieści, o skomplikowanej osobowości i tożsamości – posłużyło pisarzowi w próbie zdiagnozowania zbiorowego ducha współczesnych Czechów. Z powieściowego świata Grandhotelu wyłaniają się dwa zasadnicze wymiary: egzystencjalny z całą galerią indywidualności poszukujących swojego miejsca na ziemi, z ich pogmatwanymi „liniami życia” i osobistymi dramatami; oraz zbiorowy, historyczno-społeczno-kulturowy, wypełniony skomplikowanymi dwudziesto…
Urban Heat Island and air quality, Dijon, winter 2014-2015.
2016
For the 2014-2015 Winter, thetemperature patterns and the Air Quality measured over the Grand Dijon urban area are studied together.Meteorological conditions favoring the development of an Urban Heat Island (UHI) are distinguished fromthose giving rise to pollution episodes. Winter UHI are next characterized, with radiative situations followedafter the sunset by relatively strong UHI (about 3°C), and days with no insolation during which anthropogenicheat is suspected to produce a small UHI (few tenths of °C).
Discriminating impacts of geomorphological and human factors on vineyard soil erosion (Burgundy, France)
2014
International audience; The Burgundy vineyards have been recognized for the high diversity of Terroirs, controlled by complex interactions between natural features, historical parameters and soil management practices. Vineyards are known to undergo substantial soil loss in comparison with other types of agricultural land. Hydric erosion on vineyards is controlled by complex interactions of natural and anthropogenic factors leading to intra-plot spatial heterogeneities of topsoil at a scale of a metre. Studying the relationship between soils and their degradation is crucial in this situation where soil sustainability is threatened. This study explores the relative influences of historical an…
Prawa człowieka w rzeczywistości globalnej wioski
2015
The area widely and loudly discussed, often raised in the public discourse is the topic of human rights. This topic is not new, it was already known in antiquity. Today it acquires a specific context of a shrinking global reality. As a result of computerization and media the world has become a global village, in which the events happening in the one place can at the same time can be reported in another. On the one hand we can see the cultural diversity and on the other there is a global diffusion of symbols and values. So does globalization help or impede the adoption of the same rights as fundamental human rights? Is the universality of these rights possible? Or perhaps cultural difference…

Performance of the cost-effective Planacon ® MCP-PMTs in strong magnetic fields
2020
We present the behavior of the cost-effective Planacon MCP-PMTs with pore diameter in the presence of axial magnetic fields up to 0.5 T. Having a batch of 62 devices of the same type, two MCP-PMTs were selected and their gain variation measured in different magnetic fields. These two otherwise identical devices satisfied the selection criteria by requiring the lowest (1.15 kV) and one of the highest (1.4 kV) bias voltage values to achieve a given gain. Both MCP-PMTs have a nearly identical tolerance of the strong magnetic field despite the significant difference in the bias voltage. This clarifies the mechanism of the B-field influence on the MCP-PMT gain, emphasizing the importance of the …
The role of maternal effects in host-parasite interactions: examination of the development of the immune defense in a colonial seabird, the black-leg…
2004
One of the main aims of evolutionary biology is to understand the mechanisms responsible for the phenotypic variation on which natural selection can act. Maternal effects occur when a mother's phenotype or her environment influence her offspring's phenotype. Despite the importance of such effects for the ecology of host-parasite interactions, their role has been relatively neglected to date. In this thesis, we examined how mothers influence the immune defense of their young in an environment that varies in space and time. This work has primarily focused on a colonial seabird, the black-legged kittiwake (Rissa tridactyla). Using this model, we have first shown that specific maternal antibodi…
Post-synthesis alumination of MCM-41: Effect of the acidity on the HDS activity of supported Pd catalysts
2010
Abstract Siliceous MCM-41 with different amount of alumina, from 0.25 up to 4.0 wt%, were prepared by impregnation of the MCM-41 with aqueous solution of Al(NO) 3 ·9H 2 O. The modified mesoporous silicas were then used as supports for Pd catalysts prepared by wet-impregnation from PdCl 2 precursor. Supports and corresponding Pd catalysts were characterized by XRD, XPS and NH 3 -TPD. The catalytic behavior was tested in the hydrodesulfurization (HDS) reaction of thiophene. An increase of the hydrodesulfurization activity with increasing alumina amount up to 0.5 wt% was observed. On the basis of the acidity change of the support and the structural modification underwent by the deposited palla…
EPR/ALANINE PELLETS WITH LOW Gd CONTENT FOR NEUTRON DOSIMETRY
2013
This paper reports on results obtained by electron paramagnetic resonance (EPR) measurements and Monte Carlo (MC) simulation on a blend of alanine added with low content of gadolinium oxide (5 % by weight) to improve the sensitivity to thermal neutron without excessively affecting tissue equivalence. The sensitivity is enhanced by this doping procedure of more an order of magnitude. The results are compared with those obtained with the addition of boric acid (50 % by weight) where boron is in its natural isotopic composition in order to produce low-cost EPR dosemeters. The gadolinium addition influences neutron sensitivity more than the boron addition. The presence of additives does not sub…
