The paper contains a literature review of studies on several firearms operation systems and a review of articles on modern methods of calculating the kinematic characteristics of weapons. It includes the presentation of the short recoil operated 9 mm PW INKA pistol numerical model. The model was created in the MCS Adams software which uses the multibody systems. The boundary conditions for each part were specified and their implementation was determined. As the preliminary results of numerical investigations, the slide and barrel velocity and displacement curves were obtained. Comparison of a numerical solution with the literature data allowed for its qualitative verification.

Polarization Characteristics

Multi-frequency radio polarization observations of external galaxies are now available. The resolution is such that we can sample many positions over the galaxy, and different scale sizes. Faraday rotation measures, initial polarization angles, and depolarization can be used as indicators of magnetic field morphology in the source. In order to interpret the variation of polarization characteristics with frequency, a numerical model of Faraday rotation in galaxies is being developed. Preliminary results show that a wide range of situations can be investigated with the model.

ABSTRACTIn the framework of the Enresa 2000 PA exercise and as a continuation of the developments made during SR 97, we have developed a conceptual and numerical model to calculate the release of radionuclides from spent fuel under repository conditions. The model includes both thermodynamic and kinetic considerations. Hence, although certain radionuclides are solubility controlled, for other radionuclides their release is governed by kinetic processes such as radiolytically promoted oxidative dissolution of the matrix and the associated water turnover inthe gap. The fluxes of selected radionuclides are calculated as an indication of the relative importance of the various processes considered to define source term concentrations in the performance assessment of the spent fuel repository.
