New heading of the journal: Pages of memory

Abstract

BACKGROUND: Relevance. In the development of Russian dentistry, one can clearly trace the emergence and gradual formation of two independent directions that merged together only after the October Socialist Revolution. The first of them is connected with the organization and treatment of maxillofacial wounded, the second with the organization and treatment of dental diseases. It is impossible to imagine the development of these areas without specialists who have made a unique contribution to the development of domestic and world dentistry and maxillofacial surgery. The Russian Journal of Dentistry opens a new section Pages of Memory, which will be dedicated to prominent scientists, clinicians, organizers of dental care, as well as prominent public figures of healthcare. This section begins with materials about the life, professional activity and contribution to military and practical dentistry of academician, Colonel-General of the medical service Fyodor Ivanovich Komarov.

On the distribution of charge carriers in branches thermoelectric cooler

“…Since practically used thermoelectrics are doped semiconductors of the n-or p-type, usually carriers of only one sign are taken into account during optimization, which are the main ones. There are at least two ways to increase efficiency by doping: this is the optimization of the efficiency parameter in the operating temperature range [2] and the use of the distributed Peltier effect [3]. In these and other studies devoted to the optimization of charge carriers, charge carriers of only one sign are taken into account.…”
