The Mass Function of Dark Halos in Sup erclusters and Voids E. P. Kurbatov1 1 ,* Institute of Astronomy of the Russian Academy of Sciences A mo dification of the Press­Schechter theory allowing for presence of a background large-scale structure (LSS) ­ a sup ercluster or a void is prop osed. The LSS is accounted as the statistical constraints in form of linear functionals of the random overdensity field. ... Variance as a function of mass for different sets of constraints. ...

... Day З In common usage the word "day" unfortunately has two different meanings: (1) the period of time when the Sun is up (what we have been calling "daytime") (2) the period of time between consecutive sunrises (or sunsets), or one daytime + one nighttime. ... The sky turns dramatically dark and bright stars and planets can be seen. ... З The planets move roughly along the same path as the Sun and Moon. ... The Moon took a month to circle the sky, the Sun a year, each planet its own period of time. ...
