The article describes two independent observations of swimming in the European Mole (Talpa europaea) and provides a review of previously published records. Moles are primary terrestrial mammals but different phylogenetic lineages show different attitudes to water/moist habitats. and Jan Robovský a kol.
The fact that recent demographic data have been pointing to gradual but consistent dying out of Europe has become the key point of strong philosophical, political and other clashes in the last years. Most discussions focus especially on the issues related to the causes of this situation, thus rather omitting the real consequences on everyday lives of Europeans in the upcoming decades. Namely the economic and sociological impacts. The structure of population change in terms of nationality is the second important process in today’s Europe: The majority population comprising original nationalities on whose basis the state composition of Europe had been formed is gradually losing its dominance. Conversely, immigrants (particularly Muslims) and their children are gaining more and more influence on the structure of society. Various kinds of economic pressure are related to these processes, which in the future will inevitably grow into the shape of events completely changing the society and its economic system. I assume that in order to maintain its economic power, traditional European population will go through a process, during which some usual democratic principles and traditions will be put aside, for example the attitude towards the right to vote will change. That is because despite many complications, traditional European society will behave quite economically by keeping its political power as a guarantee of its economic power, and particularly as a guarantee that the standards of living and thus the possibility of satisfying one’s needs - manifesting itself through life style, among other things - will be preserved., Luboš Smrčka., and Obsahuje seznam literatury
Two elementary processes - unaxial compression and creep - were chosen to demonstrate some structural effects in the mechanical behaviour of particulate materials. Six aspects of it - density, grain crushing, angularity, water effect, diffusion and garlandlike creep - were dealt with using firstly theoretical hypotheses and verifying them afterwards by laboratory experiments. Granular clay, silica gel, sand and oat flakes were experimented with. It was shown that the effect of density can be masked by other factors, granulometrical curve may change - due to grain crushing - its shape from Gauss-Laplace to concave form, angularity may radically modify the stress-strain curves, water may initiate hydrocollapses, dry granular material if loaded may be subjected to diffusion and creep may acquire a hybrid form (mixture of diffusion and garlandlike varieties). Various species of nonstandard behaviour have been described. and Obsahuje seznam literatury
