[Gene pool differentiation between Altaic and trotting horse breeds inferred from ISSR-PCR marker data].

Using ISSR-PCR marker data, comparative analysis of the gene pools of Altaic and trotting horse breeds was carried out. Horse groups of different origin demonstrated differences in amplification spectra of DNA fragments flanked by inverted repeats of four microsatellites. Combinations of certain DNA fragments present in these profiles reproducibly distinguished genomes of the Altaic breed from the trotting breeds.

On limb radiance calculations and convergence of relaxation type retrieval algorithms.

Several approaches to the solution of the radiative transfer equation assume either Curtis-Godson average or linear change of the source function across grid segments. When such solutions are used for calculating limb radiances, the peak radiance response to the source function perturbation at tangent point i is displaced down to the tangent point i+1. This effect is explained through a geometric argument.
