The article presents an analytical solution to deterministic problems of infinite fatigue life (determining the safety factor, predicting tha carrying capacity and proposing the cross-section dimensions) of machine parts subjected to arbitrary pure harmonic loading. Presented mathematical models do not require to construct any fatigue strength diagram adopting it only as a basis of graphical solving. Finally, these models may serve as a starring point formulating analytical solution to deterministic problems of infinite fatigue life of machine parts under combined harmonic loading. and Obsahuje seznam literatury
The author devoted her study to íhe process that lead to the conclusion that certaln types offood can be considered an ethic feature of a nation. As an example she chose the Slovák nationalfood, Bryndz halušky (a type of roundpasta dumpling with goats cheese). In the first part she explains the origin and genesis of the basic ingredients for this food and its sociál and geographic correlation. Another part is devoted to an evaluation of relevant materiál from ethnographic, historical and cultural sources. She points out that the adjective Slovák or national was applied to a wide range offood and drink in the 19th and beginning of the ťwentieth century and that Bryndz halušky were first labelled the
Slovák national dish by Czech author B. Němcová, Later the author devotes attention to the self-identijication of Slovaks after the formation of Czechoslovakia in 1918 from a point ofview limited to national cuisine. She explains why the nationalfood ofSlovakia,
as one of its ethnic symbols, has its origins in the culture and traditions of the Carpathian mountain region. Further examples are given from the area of Slovák national art. In concluding the study, the author States that the process, by which a food, originally
a regional speciality associated with a specific sociál group, came to be presented as a national food, is not unique in Europe. On the contrary it is quite common and in most cases dosely linked with the forming of the national consciousness.
