Analysis of the electron component of EAS at observational level 700 g x cm(-2) with a scale breaking interaction model and gammaisation hypothesis

Scale breaking model and gammaisation processes for high energies give a correct description of the longitudinal development of extensive air showers (E.A.S.). From the analysis of phenomenological characteristics of E.A.S. at Tien-Shan experiment, it follows that for energies near 10 to the 6 GeV the secondary particle multiplicity increases with energy faster than is predicted by the accepted scale breaking model

A Catalog of Very Isolated Galaxies from the SDSS Data Release 1

We present a new catalog of isolated galaxies obtained through an automated systematic search. These 2980 isolated galaxies were found in approximately 2099 sq deg of sky in the Sloan Digital Sky Survey Data Release 1 (SDSS DR1) photometry. The selection algorithm, implementing a variation on the criteria developed by Karachentseva in 1973, proved to be very efficient and fast. This catalog will be useful for studies of the general galaxy characteristics. Here we report on our results.Comment: 67 pages, which includes 14 figures. Accepted for publication by A

A study in university students on the applied methods of transferring information through integrated teaching of anatomy

Ten years ago we introduced an integrated method in the teaching of Anatomy at a university level. It incorporates not only the classical methods of teaching, but also the use of electronic devices. The surveyed students are from five different courses. Despite their various specialization and qualification goals, they all share an insufficient amount of academic lessons on the difficult subject of Anatomy. The aim of this study is to improve the teaching practice, using the method of student feedback. We proposed a short survey to the students, after they completed their Anatomy course. The results were organized into tables and consequently were statistically analyzed. The following report is an analysis of the received data on the importance of the individual teaching methods in the context of integrated teaching. During the study the principle of voluntary participation was explicitly used.
