One of problems in terrain surveys in geology and archeology is sample obtaining. Among all possible complications are limits in sample volumes and masses, including possible toxicity or radioactivity and also the legal status of the samples. In his contribution, these problems are addressed by application of microsampling by surface exfoliation of geological objects and archaeologic artifacts using various tapes and subsequent analyses of the resulting samples. Among method used were both optical and electron mic...

Influences of earthquakes on nuclear power plants and their parts are studied in frame of nuclear safety. In the past, the authors have dealt with the effects of earthquakes and vibrations in the primary circuit. However, it cannot be omitted that the seismic influences can show up also on the secondary circuit. Turbines installed in secondary circuits of nuclear power plants are big and heavy machines. For example the turbine installed in JETE (Temel?n Nuclear Power Station ? Czech Republic) generates 1003MWe. It...
