The article describes the visualization of the space of initial excitation area in sinoatrial node of the cat’s heart
In patients, there has been registered luminescence of
skin sites affected by basal cell skin cancer at stage III
in high-frequency electric field. The diagnosis was
confirmed by histological analysis of excised cancer
sites
It is proposed to use the visualization method of
propagation of excitation in the nerve in a highfrequency
electric field
Oak Durmast and English Oak researches on a sanitary-pathological condition of oak stands are conducted in different growing conditions direction of slopes, forest stand height on a slope (top, average, bottom) and cutslope ratio (5 – 15º and 25 – 35º)
In the article we present the data of empirical research of life values and life-purpose-orientations of teenagers - children Kurdish migrants living in the village of Preobrazhensky of Adygea
The article presents the data on vitality and age
structure of Beckmannia syzigachne and
Calamagrostis langsdorffii соеnopopulations under
conditions of the Lena-Viluy interfluve. The study
revealed 3 types of vitality of Beckmannia syzigachne
(prosperous, equilibrium, and depressive), 2 types of
vitality of Calamagrostis langsdorffii (prosperous and
depressive). The age spectrum in both species is
normal, non-complete, left-sided. According to the
delta-omega classification, the coenopopulations are
considered to be young
The article presents the results of studies of vitality
and of the correlation variability of morphological
traits cenopopulations Lilium pensylvanicum Ker.-
Gawl. on the natural territory of the Yakutsk Botanical
Garden and in cultura. The study shows variability of
their parts (variability) and the estimation

The article is devoted to the analysis of wide public
discussions, permanently renewable in Imperial Russia
during 1860-1990 in the connection with an organization and activity of peasant courts
In agricultural production, the direction of introduction
of renewable energy for power consumers remote from
the external electrical network is relevant. Here,
prospects are revealed in front of the solar PV stations.
One of the main functional units of solar power is
inverters that convert the DC voltage of the solar
panels into alternating current. The article describes
the advantages and disadvantages of the main methods
of voltage regulation of the autonomous inverters of
solar photovoltaic power plants. We have proposed
new structural designs of autonomous voltage
inverters, described their advantages, features of
design and operation for voltage stabilization. We
suggest stand-alone inverters designed using high
frequency link, which will significantly improve mass
and dimensions parameters of the converter. Due to the
use of single-phase transformer with a rotating
magnetic field in stand-alone inverters, we improve the
efficiency of the converter and the reliability of the
work. Patents of the Russian Federation confirmed the
novelty of technical solutions of the considered
schemes of autonomous voltage inverters. Structural
schematics of the voltage regulators considered in the
article, as well as features of their work, will allow to
increase efficiency of preliminary works on
development of autonomous voltage inverters with
improved operational and technical characteristics for
solar photovoltaic power plants
In the article we have considered the technical solutions of voltage regulators and the frequency of current of the asynchronous generators of the wind power installations executed with the help of the direct frequency transformers. The comparative analysis of them has been carried out as well
