Indices of dental health in children and adolescents from Saratov and the Saratov region

<p>Objective: to determine the level of dental health in children and adolescents living in the Saratov region. Material and methods. To assess the intensity and prevalence of major dental diseases 1510 patients have been examined by the method recommended by the WHO Collaborating Centre in Russia. Results. A comparative analysis of caries and occurrence of different types of teeth-maxillary anomalies among children aged from 3 to 18 years. Conclusion. The epidemiology of major dental diseases in the Saratov region is characterized by the significant spread of caries from 70 to 94,6% in the different age groups. The proportion of people with malocclusion among the surveyed reaches 46,6%.</p

A detailed literature reviewing, analysing the multiple and confusing concepts around the ideas of information literacy and digital literacy at the start of the millennium. The article was well-received, and is my most highly-cited work, with over 1100 citations

ELECTRONIC STRUCTURE OF AMORPHOUS Si3N4

On a effectué l'interprétation des états électroniques dans la bande de valence et la bande de conduction du Si3N4 amorphe et on a établi le diagramme des énergies d'après les spectres d'émission et le rendement quantique de SiK -, SiL2,3 -, NK en combinaison avec les données de la spectroscopie des photoélectrons de rayons X des couches internes et de la bande de valence.There is performed interpretation of electronic states in valence and conduction bands of amorphous Si3N4 and constructed an energy diagram of electronic levels using X-ray SiK -, SiL2.3 -, HK - emission and quantum yield spectra in combination with the XPS data of inner levels
