In this work the first results of the creation of a substorms catalog including the mid-latitude positive bays (MPB) registered at the Bulgarian station Panagjurishte (∼37° GMLat, ∼97° GMLon) are presented. MPB index characterizes the mid-latit

The goal of this work is to examine the effects of the “expanded” or “high-latitude” substorms at mid-latitudes. These substorms are generated at auroral latitudes and propagate up to geomagnetic latitudes above ∼70° GMLat. They are usuall

SUMMARYHuman papillomaviruses (HPV) are small, non-enveloped viruses with a dsDNA genome. About 40 HPV types infect the mucosa and skin of the anogenital tract, and they are further subdivided into low-risk HPV (LR-HPV) and high-risk HPV (HR-HPV). Lo

In the present work, the variations in Total Electron Content (TEC) induced by changes in the ionizing radiation of the Sun, which are related to the rotation period (about 27 days), were investigated. This study was based on a 30-year period. The re
