Domestic schools of architectural restoration in the XX century

One of the aspects of the development of Russian architectural restoration in the twentieth century was the selection and formation of regional architectural restoration schools. The purpose of the study: to identify the features of the leading schools of Russian architectural restoration in the twentieth century. Methods: a comprehensive study, comparative analysis of architectural and restoration practices of Moscow, Novgorod, Vladimir-Suzdal, Leningrad, Pskov restoration schools based on the generalization of bibliographic material. Results: the role of architectural and restoration schools in the development of scientific theory and practice of restoration in the twentieth century is Revealed.the features of restoration techniques and methodological approaches of Moscow, Novgorod, Vladimir-Suzdal, Leningrad, Pskov restoration schools are Analyzed. The influence of the typological and architectural and artistic context, the degree of its preservation, on the specifics of architectural and restoration activities of individual schools is revealed. The prevailing types of restoration (integral, fragmentary, compromise, synthetic) at the main stages of formation of domestic restoration schools are determined

Nanoparticles of Bioactive Metals/Metal Oxides and Their Nanocomposites with Antibacterial Drugs for Biomedical Applications

The increasing appearance of new strains of microorganisms resistant to the action of existing antibiotics is a modern problem that requires urgent decision. A promising potential solution is the use of nanoparticles of bioactive metals and their oxides as new antibacterial agents, since they are capable of affecting pathogenic microorganisms by mechanisms different from the mechanisms of action of antibiotics. Inorganic nanoparticles possess a wide spectrum of antibacterial activity. These particles can be easily conjugated with drug molecules and become carriers in targeted drug-delivery systems. This paper discusses the benefits and prospects of the application of nanoparticles from metals and metal oxides and their nanocomposites with antibacterial drugs
