... An Analysis of Modern Discrete Movements of the Earth's Crustal Blocks in Geodynamically Active Regions Based on GPS Data V. S. Zakharov and D. A. Simonov Moscow State University, Moscow, 119991 Russia e mail: zakharov@dynamo.geol.msu.ru; simon@geol.msu.ru Received March 24, 2009 Abstract--In this work original algorithms are proposed that allow us to provide a set of points (clusters) on a surface that are in cooperative motion, on the basis of an analysis of GPS data. ...

... Fluorescence induction curves registered from individual microalgae cenobiums in the process of population growth. ... Registration of chlorophyll fluorescence induction curves (IC) from individual microalgae cenobiums was performed during Scenedesmus quadricauda culture growth. ... Recording of the fluorescence induction curve for each individual cenobium was performed during 200 s. In the process of algae cultivation (52 days) 846 fluorescence kinetic curves were recorded. ...

For separation of anisotropy and inhomogeneity influence we recommend non-symmetrical rotation of arrays (for example, to rotate the D - array around the center of AB (or MN), instead of spacing center) and analysis of azimuthal diagrams' spectrum (Bolshakov et al., ... Dipole equatorial array is not so convenient for asymmetrical rotation, at which one dipole is gone along a circle’s arch, while other dipole turns around its center. ...
... Synchronous Evolution of Galaxies in Groups: NGC 524 Group O. K. Sil'chenko and V. L. Afanasiev 245 ISSN 1990-3413, Astrophysical Bulletin, 2012, Vol. ... Four of the five galaxies revealed synchronized bursts of star formation in the nuclei 12 Gyr ago. The only galaxy, in which the ages of stellar population in the nucleus and in the bulge coincide (i.e. the nuclear burst of star formation did not take place) is NGC 502, the farthest from the center of the group of all the galaxies studied. ...
