Dissimilarities in living of the psychical strain of men and women in the police of the Czech republic
SCHMIDT, Václav
This extended essay points out the problems of living of the psychical strain of men and women in the Police of the Czech Republic. It tries to reveal policemen´s work in the place of a criminal offence and to show some risks of this job in connexion with the influence of stress. The extended essay deals with some problems of an exacting character of the metioned occupation and the mutual comparsion of differences in living between both the sexes, origin and influence of stress on the man´s psychic as an individual. In addition to a simple division of successive parts and the organizational structure of the police, here are mentioned some descriptions and definitions of stress and its influence on the man´s sphere and areas. The essay tries to elucidate the criminologist´s work to a reader and to understand some stress situations in the execution af a policemen´s exacting job. It deals with women´s status in the society, too, namely both from a historical point of view and in the present as well. Some statistical data concerning the perpetrated criminal offences in the region of South Bohemia and numbers of policemen and policewomen are metioned here, too.

Stress state interpretation based on focal mechanism solution
Ptáček, Jiří ; Mořkovská, E.
Důlní otřesy vznikají za spolupůsobení přírodních a technologických faktorů. Obecně se má zato, že hlavními příčinami horského otřesu jsou nepříznivé geologické a geomechanické vlastnosti strukturních jednotek horského masivu a konsekventně tím způsobená nepříznivá, nerovnoměrně rozložená napěťová pole. Pro verifikaci tvaru napěťových polí a strukturního, napěťodeformačního modelu interpretovaného na základě paleonapěťové analýzy v české části hornoslezské pánve byla v rámci řešení projektu GAČR realizována měření pro zjišťování recentních napětí. Záměrem výzkumu bylo vytvoření modelu napěťodeformačních polí v sedimentárním uhelném ložisku a jeho srovnání s původním modelem interpertovaným na základě paleonapěťové analýzy. Pro studium byla vybrána nejvýchodnějčí část karvinské dílčí pánve.

Stress - one of the most important mining influenced factors
Waclawik, P. ; Ptáček, Jiří
Stress is one of the basic factors affecting rock massif behaviour by decisive way. Knowledge of stress fields facilitates projection and successful realization of workings (e.g. stability check of workings, behaviour of proposed supports, spatiotemporal situation of workings). Within the scope of sedimentary deposit of Karvina subbasin were used data from structure-tectonic analysis and from measures in situ by overcoring and hydrofrac methods for determination of natural stress state and its orientation. This report deals with contemporary recognition of stress fields in the eastern part of Karvina subbasin. There are also disscussed problems of long working line depending on orientation and size of horizontal stress in this report. Last but not least there is described new knowledge about geological-tectonic structure of Karvina subbasin.

Contactless Operational Identification of Turbine Blade Stress and Vibration
Procházka, Pavel ; Vaněk, František
The study deals with the contactless vibrodiagnostic system used for identification of steam turbine blade stress and vibration. The tip-timing method based on the evaluation of time differences of blade passages in different rotor revolutions is described and the results of the development of a new contactless magnetoresistive sensor are presented. A new approach to the identification of blade stress and vibration based on the analysis of the amplitude differences of impulse blade signals is applied.

Multiinstrumental analysis of the effect of cadmium ions on selected flax cultivars
Kryštofová, O. ; Baloun, J. ; Húska, D. ; Diopan, V. ; Shestivska, V. ; Zítka, O. ; Adam, V. ; Macek, Tomáš ; Macková, M. ; Havel, L. ; Kizek, R.
Multiinstrumental analysis of the effect of cadmium ions on selected flax cultivars was performed, revealing marked differences in synthesis of protective compounds by chromatographic, spectrometric and electrochemical techniques.
