For an infinitely long circular cylinder, the solution of the light scattering problem for the perpendicular incidence was first derived by Rayleigh [ 418 ] who returned to this problem once again in his last work [ 417 ] written a short time before his death. The problem for oblique incidence was solved in 1955 by J.R. Wait [ 491 ] (Kerker [ 274 ] at p.256 mentions also the paper of Blank, 1955); a bit later the same result was obtained in [ 172 ]). ...

... Actor Prolog supports so-called repeated proving of sub-goals. ... Logical actors are a name of these repeatedly proved sub-goals. ... A logic program consists of sub-goals that must be proven in the course of an execution of the program (like a usual imperative program consists of commands to be executed). ... There are some logical actors in the outside world from the standpoint of the ideology of Actor Prolog , and a program interacts with these external actors. ...

Since the days of Sputnik and Explorer 1, thousands of spacecraft have gone into space, some of them carrying human passengers. The first person to orbit the Earth was the Russian Yuri Gagarin, on April 12, 1961. The first American to do so was John Glenn, who completed three orbits on February 20, 1962; more than 26 years later, at age 77, Glenn returned to space aboard the space shuttle. ... in orbit. ...

... In order to describe the effect of distortion of the trajectory of an electromagnetic wave in atmosphere, it is needed to use the solution of the dispersion equation of moving medium electrodynamics for the spatial case of atmosphere motion. The solution of the dispersion relation for the propagation of an electromagnetic wave in a medium is valid for an atomic layer with a thickness on the order of a few wavelengths of the electromagnetic radiation. ...
