Fluorine is one of the most widespread elements on our planet. Its content in brewing by-products (spent grains, malt culms, yeast), which are used for the preparation of animal feed is limited in accordance with Regulation No 356/08 of the Czech Republic law. This Regulation reflects the guidelines of the European Committee 2008/76 / EC of 25 July 2008 and Commission Regulation EU No 574/2011 of 16 June 2011 and determines its limit in brewing by-products at 150 mg/kg. The paper is focused on information about fluorine occurrence in the environment and about potential harmful effects of increased fluorine intake on animal and human health including...

The article deals with the kinetics of the pressure growth in the headspace of the bottle filled by carbonated beverage after the rapid opening and closing of the output valve placed on the bottle neck. The rate of pressure growth was measured by an electronic pressure recorder with quick response. Escape of CO2 was also initiated by electrolysis or by inserting a porous material into beer. The pressure growth in the bottle can be described by a simple kinetic equation with two parameters, the initial rate of pressure growth and the constant describing the suppression of bubbles detachment from the surface of the solid particles. Continuous removal...

The article informs about a research of an early modern malt house in Chanovice chateau (Klatovy district). The malt house was analysed during renovation works in 1996-8. The multi-disciplinary research included a research of written sources, an architectural and historical survey, use of available iconographic sources, an archaeological research, an archaeobotanical analysis of a sample of found carbonised grains and an anthracology of the same sample. The archaeological research and the architectural and historical survey revealed a uniquely and completely preserved malt house originating in the 16th century and destroyed probably in the 19th century....
