2. Intro
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. ...

5. Why Asteroid 2008 TC3 Represents a Landmark - Dr David Asher, from Armagh
... A hundred years later, a handful of Tunguska-sized asteroids have been spotted by telescopes, but most remain unseen. The asteroid designated 2008 TC3 , which made the news on October 6th before colliding with the Earth on October 7th was too small to constitute a part of the "Earth impact hazard". ... 2008 TC3, for example, finally exploded in the atmosphere above Sudan . ...

Marc White . ... Turbulent entrainment processes may play an important role in the outflows from young stellar objects at all stages of their evolution. In particular, lateral entrainment of ambient material by high-velocity, well-collimated protostellar jets may be the cause of the multiple emission-line velocity components observed in the microjet-scale outflows driven by classical T Tauri stars. ...
