In this review article, we present the main results from our most recent research concerning oscillations of fast rotating neutron stars. We derive a set time evolution equations for investigation non-axisymmetric rapidly compact objects in full general relativity, taking into account contribution dynamic spacetime. Using code, which features high accuracy at comparably low computational expens...

Context. Several fast radio bursts have been discovered recently, showing a bright, highly dispersed millisecond radio pulse. The pulses do not repeat and are not associated with a known pulsar or gamma-ray burst. The high dispersion suggests sources at cosmological distances, hence implying an extremely high radio luminosity, far larger than the power of single pulses from a pulsar. Aims. We s...

The modelling with the Geant4 toolkit of moderated 3He-filled proportional neutron counters is studied. The energy deposition spectra by the neutron capture products in the gas counter is compared with experimental results. On the other hand, efficiency calculation for polyethylene moderated proportional counters are compared with experimental and MCNPX results.Finally, the application of the G...
