František Záviška. Inventory of personal papers
Haasová, M. ; Kábová, Hana
František Záviška (1879-1945)habilitated in theoretical physics at Charles University (Prague) in 1906, he was appointed professor extraordinarius in 1914 and professor ordinarius in 1919. He studied in the Cavendish laboratory in Cambridge (1906/7). He was physicist, primarily engaged in physical optics, theories of electromagnetic fields and hydrodynamics. He became member of the Royal Bohemian Learned Society (1919), the Czech Academy of Sciences and Arts (1914) and the Association of Czechoslovak Mathematicians and Physicists (1898). His personal papers are housed in 14 boxes. Biographical documents are rather rich as regards his study and university career, though correspondence, scientific work and documentation from his public activities are scarce. Set of testimonies of Záviška's death, obituaries, memories and articles to jubilees are an important part of the fonds. Documentation of his wife, Emilie Antonie, née Škodová, is preserved, too.

Modeling of Transformation of Coal-N to Nitrogen Oxides in Fluidized Bed Combustion
Svoboda, Karel ; Pohořelý, Michael
The report contains an overview of transformation phenomena and reactions for coal nitrogen leading to nitrogen oxides emissions. Initial nitrogen in volatile matter from coals is considered in three forms: NH3, HCN and N2. The precursors (NH3 and HCN) are oxidized primarily to NO and N2O and further they react with carbon, CO and NH3. The nitrogen from coal-char is directly oxidized to NO ane N2O,which can be reduced by carbon and CO. An attempt has been made to quantitatively characterize effect of coal properties and combustion conditions on nitrogen oxides emissions.

Equilibrium Concentrations of Solutes Extracted from Plants with Supercritical CO2
Sovová, Helena
Phase equilibrium is the crucial factor for extraction feasibility and rate. In supercritical fluid extraction from plants it depends not only on extraction pressure, temperature, and solvent composition, but also on solute-matrix interaction and on mutual interactions of solutes. A new method for measurement and quantification of these phenomena is reported, as well as some results obtained in the project.

Kdy se platí v „ženských“ povoláních více?
Jurajda, Štěpán ; Harmgart, H.
In this paper, we use a 1995 sample of social-security wage records of full-time German workers to show that in East Germany predominantly "female" occupations pay more to both men and women and that there is no relationship between occupation-specific concentration of women and wages in West Germany.
