Context. Cassiopeia A is one of the most extensively studied supernova remnants (SNRs) in our Galaxy. The analysis its continuum spectrum through low-frequency observations plays an important role for understanding evolution radio source and propagation synchrotron emission to observers SNR environment ionized interstellar medium. Aims. In this paper we present measurements integrated Cas chara...
Planetesimal formation is a crucial yet poorly understood process in planet formation. It widely believed that planetesimal the outcome of dust clumping by streaming instability (SI). However, recent analytical and numerical studies have shown SI can be damped or suppressed external turbulence, at least outer regions protoplanetary disks are likely weakly turbulent due to magneto-rotational (MR...
OBJECTIVES The study was undertaken to investigate vancomycin-resistant (vanA) Enterococcus faecalis isolates carrying aggregation substance (AS) gene(s) for their ability to co-transfer vanA and AS genes. METHODS Six vanA clumping-positive E. faecalis isolates (five human and one food sample) carrying one or more AS genes (prgB, asa1, asa373) were analysed for co-transfer of vanA and AS gene...
