Abstract The Southern Federal District is one of the main grain-producing regions of the Russian Federation. The share of the Southern Federal District, in which the Rostov Region is located, accounts for 12-15% of the total Russian barley production. In solving the problem of a further increase in yield and an increase in the quality characteristics of grain, the priority belongs to the variety. As a result of a long-term study of the collection of naked barley, sources of valuable traits and properties were identified: high grain content of an ear: K-9010 (Turkey), Akka (Israel), Nuda Bianco (Italy), 1057-1923 (Czech Republic), Buck CDC (Canada), K-266 (Pakistan); the number of productive stems per unit area: Kitaki-nadaka (Japan), K-11182 (Japan), K-3772 (Dagestan), Golozerny (RF); early maturity: Omsk golozerny 1 (RF), Brunee (Ethiopia), NB-owa (Nepal), K-11182 (Japan), Golozerny (RF), K-3038 (Turkmenistan), K-3426 (Japan), K-19103 (India), K-26598 (Ethiopia), K-266 (Pakistan), Korona Laschego (Poland). Over the years of research on a complex of traits, a number of samples have been identified that combine a high potential of grain productivity with resistance to lodging, different duration of the growing season and plant height: K-26598 (Ethiopia), 84469/70 (Czech Republic), CDC Dawn (Canada), Holozerny (RF), 1057-1923 (Czech Republic), Omsk Holozerny 1 (RF), K-6099 (Afghanistan), Akka (Israel), Kitaki-hadaka (Japan).

The fixed mixed prosthetic restorations (FMPRs) are often manufactured in dentistry. Fixed prosthetic restorations mixed (RPFM) are often used in dentistry. The aim of the study was the presentation of the deficiency and the differences arising between FMPRs with metallic framework plated with two types of dental resins, currently used frequently in Romania, Superpont C + B (Spofadental, Czech Republic) and Royaldent (Palatine Foggyart, Hungary). We have achieved at 102 patients, 132 FMPRs coated with Superpont C+B and Royaldent resins. Patients were divided into two equal groups according to dental polymer used for coating. Long-term study was conducted by biannual monitoring, over three years. The results of the study showed that both resins degrades over time, from the point of view of their physical appearance and their aesthetics, and induced the apparition of gingival inflammation, but restorations coated with Royaldent resin showed less irritation of the gingival tissues.
