Retention device
The claimed utility model relates to medicine, directly to dentistry and orthodontics, and concerns the design of the retention device. The retention device consists of: a base 1 shortened from the roof of the mouth from photopolymer plastic and two rows of a reinforcing polymer filament 2 with a diameter of 0.35 mm, extending from the vestibular side, then continuing in the base of the device and covered with a photopolymer plastic in the cheek-b side of the crowns teeth 3 without overlapping their cutting edges and occlusal surfaces. The retention device provides an improvement in the result of the retention period after correction of various anomalies of the dentition and anomalies of the teeth.
The project to develop a cellular model of the placenta became the winner in the Scientific Materials category of the Young Scientists 3.0 competition, organized with the support of the Presidential Grants Foundation and T-Bank.
Ten scientific journals published by RUDN University have been included in the highest level of the state list of scientific publications, the White List.
Forests are not only the lungs of the planet, but also home to millions of species. However, it has remained unclear how underground interactions between trees and fungi affect forest species richness in different climatic conditions. Previous studies have yielded conflicting results: in some regions, the dominance of certain fungi reduced tree diversity, while in others it increased it.
