Abstract. The comparative research of the influence different types auroral particle precipitation and polar cap patches (PCPs) on global positioning system (GPS) signals disturbances in ionosphere was done. For this purpose, we use GPS scintillation receivers at Ny-Ålesund Skibotn, operated by University Oslo. presence determined using data from EISCAT 42m radar Svalbard. optical aurora observ...

The plasma in the cusp ionosphere is subject to particle precipitation, which important for development of large-scale irregularities density. These can be broken down into smaller scales have been linked strong scintillations Global Navigation Satellite System (GNSS) signals. We present power spectra density regions with and without auroral precipitation based on in-situ measurements from Twin...

talon cusp is a rare developmental anomaly that occurs most commonly on the lingual side of the incisors. occurrence of the labial talon cusp is rare in the dental literature. till date only seven cases of isolated nonsyndromic labial talon cusps have been reported in the maxillary permanent dentition. however, a few cases of syndromic labial talon cusps and faciolingual talon cusps have been r...

Fig. 1. A photograph captured intraoperatively (a) and schematic representation of QAV (b) as viewed through the aortotomy. The right and left coronary cusps were almost normal in size and had sufficient effective height. While the noncoronary cusp (NCC) was relatively thick and large, the accessory cusp (AC) was too small to independently act as a competent cusp. The raphe between the NCC and ...

Equine rhinitis A virus (ERAV) is closely related to foot-and-mouth disease virus (FMDV), belonging to the genus Aphthovirus of the Picornaviridae. How picornaviruses introduce their RNA genome into the cytoplasm of the host cell to initiate replication is unclear since they have no lipid envelope to facilitate fusion with cellular membranes. It has been thought that the dissociation of the FMD...

This is a brief review of aspects galactic astrophysics and astronomy which have possible bearing on particle dark matter. It still quite normal for physicists to try solve “well known anomalies“ that are apparently seen in observations galaxies (missing satellites, cusp vs. core, etc.) whereas lot these anomalies actually been resolved many years ago. We will briefly the field discuss areas qu...
