... We address a question if globular clusters (GC) in a protogalaxy could for some time evolve chemically as isolated systems, enriching themselves with heavy elements produced in first supernova events that follow initial star formation. We determine both the critical mass of a protoglobular cluster that is needed to retain the ejecta of the very first supernova, and the critical energy (i.e., number of supernovae) that is needed to expel the residual gas from a cluster of a given mass. ...

... You will need a formal letter of invitation to get Russian visa and we will provide it to you. ... First, we will need a copy of first two pages of your passport. The best way to do it is to find a scaner, open the passport, put it on the scaner, scan it with 300 dpi resolution in grayscale mode, save as JPEG file and then send the file to ysc@bmstu.ru and please send a copy to coordinator Irina Yurovskikh yurovskikh.i@mail.ru . ...

... SHORT TERM PREDICTION OF POWER SOLAR FLARES FROM SSRT DATA .
