    On the retention of high-energy protons and nuclei with charges Z or equal to 2 in large solar flares after the process of their acceleration

    Data which suggest that the protons with energies of up to several GeV should be retained on the Sun after the process of their acceleration are presented. The protons are on the average retained for 15 min, irrespectively of the solar flare heliolatitude and of the accelerated particle energy ranging from 100 MeV to several GeV. It is suggested that the particles are retained in a magnetic trap formed in a solar active region. No Z or = 2 nuclei of solar origin during large solar flares. The absence of the 500 MeV/nucleon nuclei with Z or = 2 may be due to their retention in the magnetic trap which also retains the high-energy protons. During the trapping time the approx. 500 MeV/nucleon nuclei with Z or = 2 may escape due to nuclear interactions and ionization loss

    An Understudied Household Complex Golden Horde Period in the Entrance Area Of Kislovodsk (North Caucasus)

    The author addresses the current issue of identifying the monuments of the Golden Horde period in the Kislovodsk basin. In this archeologically thoroughly studied region of the central part of the North Caucasus, these are almost unheard of, which appears strange, as there are mausoleums and traces of settlements at a distance of 10 km to the northeast. The sources introduced into scientific circulation, long discovered, but previously inaccessible to specialists and not attributed – materials from the household pit, remains of a ceramic workshop, random finds in the entrance area of Kislovodsk, and other information and data – suggest that settled population continued to exist in the area under consideration in the 13th–15th centuries AD
