... The magnetic field of the Earth has been investigated by satellites for several decades now, and enough of it is known to model its average strength and shape during different levels of overall magnetic activity. Presently the most used empirical global magnetic field models are the Tsyganenko models (1987, 1989) , referred to as T87 and T89, respectively, although even these consist of several submodels. ...

... As a summary I present a probable model for the evolution of the nearby starburst galaxies by taking into account observations of their large-scale and nuclear gas dynamics as well as numerical simulations of gas flows in galaxies. ... Thus, it is very likely that galaxy interaction plays an important role in the formation of bars . ... A good example is the barred starburst galaxy NGC 1808. ... In fact, one can nearly see the gas flowing toward the galaxy centre where it fuels the nuclear starburst...

... Optical designers have long relied on geometric optics, or ray-tracing, to predict performance of optical instruments. ... As commonly implemented, physical optics codes unfold an optical system into a simplified linear sequence of ``thin lenses,'' which collapse the phase effects of optical elements into a plane. ... This approach accurately determines the effects of vignetting, aberrations and induced aberrations, based on the actual optical instrument geometry and prescription. ...

... An estimate the rotation period of cometary nuclei is important for understanding and describing the physical processes of the cometary activity. Unfortunately, the measurements of the rotation periods of the comet nucleus depend on the model assumptions and it is one of the main reasons for the scatter of the estimates given in various articles for a given comet. ... Right: the image of the comet 29P/Schwassmann-Wachmann 1 obtained at the 6-m telescope. ...

... The most powerful and widely used methods to calculate the scattering matrix of a fractal cluster are based on the coupled dipoles methods (e.g. the Discrete Dipole Approximation, DDA) and the theory of light scattering by a cluster of spherical particles [2-4]. ... At present the procedure of calculation of the scattering matrix is well developed for both an oriented cluster of spherical particles and for chaotically oriented clusters of such particles [4]. ...
