ABSTRACT Extragalactic jets are generated as bipolar outflows at the nuclei of active galaxies. Depending on their morphology, they classified Fanaroff–Riley type I (FRI) (centre-brightened) and II (FRII) (edge-brightened) radio jets. However, this division is not sharp, observations these sources large scales often show intermediate jet morphologies or even hybrid with a FRI one side FRII othe...

We investigate the sample of 213 GPS sources selected from simultaneous multi-frequency 1– 22 GHz observations obtained with RATAN–600 radio telescope. We use publicly available data to characterize parsec-scale structure of the selected sources. Among them we found 121 core dominated sources, 76 Compact Symmetric Object (CSO) candidates (24 of them are highly probable), 16 sources have complex...

Residual gas saturation is one of the most important parameter in determining recovery factor of water-drive gas reservoir. Visual observation of processes occurring at the pore level in micromodels can give an insight to fluid displacements at the larger scale and also help the interpretation of production performance at reservoir scale. In this study experimental tests in a glass micromod...

We propose, that the knots of the large-scale jets in powerful radio sources represent moving and separate portions of the jet matter, with the excess kinetic power. This can explain many morphological properties of quasar jets — like high knot-tointerknot brightness contrasts, frequency-independent knot profiles and almost universal extents of the knot regions — independently of the exact emis...

BACKGROUND Protein adsorption is the first of a complex series of events that regulates many phenomena at the nano-bio interface, e.g. cell adhesion and differentiation, in vivo inflammatory responses and protein crystallization. A quantitative understanding of how nanoscale morphology influences protein adsorption is strategic for providing insight into all of these processes, however this und...

We want to look at the dynamics of the coherent vortex structures which are generated at the bottom of sea waves by 1) the instability of the laminar boundary layer and the development of turbulence, 2) the nonlinear interaction of the oscillatory boundary layer with a wavy bed of small amplitude and with a sloping bottom and 3) the separation of the boundary layer at the crests of 2-D ripples ...

We present results from global VLBI (Very Long Baseline Interferometry) observations at 5 GHz of the radio source OQ208. The milliarcsecond (mas) morphology of the radio emission is described by an asymmetric compact double structure with a flux density ratio between the two components of about 10:1, and a projected total size of ∼ 7 mas (i.e. ∼ 7 pc). Both components are resolved by the presen...
