Kvasny Prum. 1984; 30(5): 102-105 | DOI: 10.18832/kp1984019
Production and export of Czech beer has a long tradition. Between 1970-80 the beer export exceeded its production andCzechoslovakiawas on the fourth place in the world export of beer. The part of beer that have been exported to the whole beer production was higher in comparison to majority of the countries that exported beer. Here, the analysis of beer export is made from the standpoint of the territorial structure and its effectivity. The level of the production base including the stage of its reconstruction as well as the main requirements to the increased stability to beer, the increased quantity of bottled beer, an enlargement of assortment offered,...

Kvasny Prum. 1984; 30(5): 105-108 | DOI: 10.18832/kp1984020
To determine the accuracy of proposed methods for a testing of beer (alcohol, extract) on a base of the values of repeatability and reproducibility a computer was used. According to the international standard ISO/DIS 5775 and British Standard BS 5497 the program in Fortran language was developed for the computer M 4030-1 inComputer center of the Corporation of Breweries and Malt-Houses Prague. The values of repeatability (r) and reproducibility (R) of the testing method were calculated from results obtained in 13 laboratories for samples. Cochran, Dixon and Youden tests were used for the verification of extreme of experimental data. With...

The practical purpose has been explained pertaining to the deposit of a sample of a new micro-organism as well as that of a reference to the registration number of a deposit in an application for the grant of legal protection of an invention in general. Requirements of the Czechoslovak Law for the deposit of new micro-organisms in events when the application concerns either a technological process in microbiology or a product or a new and artificially obtained strain. The most significant collection of micro-organism in Czechoslovak Question connected with priorities.(In Czech, English summary only)
