The problem of turbulence is one of the most important and challenging problem of the modern science. ... An experimental investigation of turbulent flows with special experimental setup and equipment, which allow to obtain reliable data with good precision, is very difficult and expensive process. ... The natural assumption for the theory of turbulence is that there exist some (unknown yet) general and universal properties for wide range of different turbulent flows. ...

... One characteristic of the ATCA dishes is that they are big by 3-mm standards. Indeed van Hoerner (1967) has considered the limits to the size of an antenna before various effects become significant. ... As the ATCA dishes are twice this, it is not surprise that the ATCA antenna gain and primary beam response varies as a result of thermal distortions. ... A gain/elevation correction will solve this - to first order at least. ... This might be an important effect for widefield imaging and mosaicing. ...

Furthermore, two SAS tasks (odffix and epicproc) had to be updated to make possible a proper SAS data reduction of simulated data. ...

. Next: FSRQs Up: THE DEEP X-RAY RADIO Previous: Redshift Distribution . DXRBS' unique combination of a dual X-ray/radio survey method and high sensitivity has opened up important, large new regions of parameter space for both blazar sub-classes, within which a large fraction of our sample (nearly 50%) lie. This section is devoted to discussing these discoveries and their impact upon our understanding of the blazar class. љ . FSRQs . BL Lacs . Paolo Padovani . 1/5/1998

FAMILIES AND SCATTERING . ... An important observation on the orbital distribution of irregular satellites is that satellite families at Saturn, Uranus and Neptune are not well defined. At Jupiter one finds 3-4 reasonably compact retrograde families, corresponding to each of the previously known retrograde irregulars and one prograde family. ... That is contrary to the current doctrine that very little has happened to these irregular satellite families following their collisional formation. ...

... In electron-positron colliders, effect of the lattice modification by opposing bunch focusing on the equilibrium radiation emittance is important at high values of the space charge parameter, so one should correctly evaluate this dynamic radiation emittance of the weak beam, which may differ a lot from the nominal emittance, already in the linear beam-beam force model. ... The linearized beam-beam force is equivalent to focusing insertion in linear lattice of the collider. ...
