... Future seminars . ... Long -term evolution of 27 days signal in solar activity and terrestrial magnetic indices - common features and differences ". ... The 27-day signal created by the solar rotation is reflected by the 27-day geomagnetic signal. We study the long-term evolution of the 27 days signal and compare its properties for solar and geomagnetic activity. ... We obtain that 'short' and 'long' period in the 27-days range are differently reflected in the solar and geomagnetic activity. ...

... The analysis shows, that asteroid ­ rubble pile loses its fast fragments in no time but the retaining fragments forms a compact structure immersed in dust ­ gas atmosphere, created by interaction of interplanetary medium with dispersed product of collisional evolution of asteroid. By interaction of an asteroid ­ rubble pile with interplanetary medium structures asteroid can increase its brightness on account of blowed up dust simulating phenomenon of distant comet's brightening. ...

In accreting binary neutron star systems matter is channelled by the strong magnetic field to the poles of the neutron star. The accreted matter accumulates at the poles to form accretion mounds. Pressure from the confined matter can significantly distort the local magnetic field structure, affecting the X-ray observations and long term evolution of the magnetic field. ...

... Table data are arranged in columns and rows, and stored in MIDAS files with the extension .tbl . ... An item in a table is accessed by giving its column and row in addition to the table name. The row number can either be given as an absolute value (i.e. the sequence number) or indicated by the value in a previously defined reference column. ... A table can be always expanded in the sense that its number of columns and rows is automatically increased when the allocated space is exceeded. ...
