Preface The necessity of the preparation and edition of such intricate publication, that is the printed version offered to the reader, of geoinformation system including the chronological catalogue and evolutionary database of the global tropical cyclogenesis is dictated, in opinion of the authors, whole number of objective circumstances. ... It derivates the serious dissensions in the initial ('raw') information as well as in databases and archives of regional cyclogenesises. ...

... Meade Instruments Corporation . ... Refracting telescopes (Meade Models NG-60, NGC-60, DS-2070AT, ETX-70AT, LXD55-AR5, LX55-AR6 ) and mirror-lens telescopes ( ETX-90AT, 105AT, 125AT, LXD55-SC8, 8LX90, LX200 GPS Series ) are generally more versatile in a wide array of land and astronomical applications. ... The intermediate-level observer, or the non-casual telescope user who wishes to purchase one telescope for a lifetime, should consider a Meade Model LXD55 series, 8LX90, or LX200GPS. ...

... Structure of Data . ... Catalog . ... In SAI OCL Catalog, we introduce our work on investigation of the Milky Way system of open star clusters. The main goal of our study is a search for new clusters using huge surveys. 168 new clusters have been already discovered by us using J,H,Ks data from 2MASS point source catalog. ... For 141 new clusters, we found their physical parameters using J,H,Ks data from 2MASS catalog and, for a number of clusters, our UBVRI CCD observational magnitudes. ...

... A nasty dispute between the Strategic Defense Initiative Organization (SDIO) and the space-science community was narrowly averted early this year when SDI officials backed down on a planned launch of a satellite with a Russian-built nuclear reactor on board. ... Early Soviet space reactors orbited for two to three months, and two Soviet Topaz 1 experiments, one for six and one 12 months, created radiation belts that disrupted the operation of scientific satellites. ...
