Spurný, František
Contribution presents new achievements and tendencies concerning the onboard aircraft and spacecraft dosimetry. Some selected results of long-term monitoring onboard an aircraft of the Czech Airlines; Review of individual aircraft crew dosimetry, particularly during 2004-2005 years. Participation at common experimental measurements onboard International Space Station (ISS); Selected results of the last ICCHIBAN intercomparison; Estimation of the neutron component contribution onboard ISS and FOTON capsule.

Vibrations of a gable of a church excited by ringing
Fischer, Ondřej ; Urushadze, Shota
The gable is of triangular shape, not being supported horizontally by the roof or any other stiffening structure. The measurements revealed that the bells excite the vibrations of towers and of the basement of the gable with moderate amplitudes, while the cantilever of the gable wall apmlifies the motion by the resonance - effect.

Teplotní závislost dodatkových molárních objemů v systémech oktan-aromatické uhlovodíky
Linek, Jan ; Morávková, Lenka ; Wagner, Zdeněk
Densities were measured for the liquid benzene and 1,3,5-trimethylbenzene, and for nine their mixtures at four temperatures between 298.15 K and 328.15 K and at pressures up to 40 MPa. An apparatus for density measurements of liquid and liquid mixtures whose main part is a high-pressure vibrating-tube densimeter working in a static mode was used for the measurement. The density data were fitted to the Tait equation and the isothermal compressibilities were calculated with the aid of this equation. Excess molar volumes were also calculated from the densities and fitted to the Redlich-Kister equation.
