The article gives an analysis of the elemental
composition in raw materials of stevia. Stevia plant is
able to regulate the flow of heavy metals, allowing
them, on the one hand, actively oppose the excessive
intake of toxic elements and on the other hand,
selectively cumulate essential elements. The contents
of essential elements in plant raw materials do not
exceed the acceptable standards regardless of the
growing conditions
The author describes the dynamics of commercial
catches and the forecasts of pikeperch catch in 2010-
2016 with an analysis of the causes that affect the
state of stocks. The analysis of the effectiveness of
the recommended pikeperch catch has been made
taking into account the factors that affected the
fishery. Researches were carried out to study the
population structure, seasonal distribution, migrations
and other characteristics of the pikeperch populations
in the Azov limans. The obtained data made it
possible to assess the state of the pikeperch stocks
and give recommendations on their rational use.
Based on the results of ichthyological studies, the
pikeperch age, length and weight composition have
been determined and its biological state has been
studied. The preliminary forecast of the stocks and
the recommended pikeperch catch in the Azov limans
for 2018 is given. The forecast of the recommended
pikeperch catch in the Azov limans for 2018 is based
on the analysis of the stocks of commercial fish
species for a number of years of observations, taking
into account the total mortality rate under the
influence of the fishery load (commercial mortality
coefficient) and the amount of replenishment of
commercial population with fish mature for the first
time
The article gives the results of the study of an effect of
mechanochemical powder of wood green of Abies
(MPA) on potato morphogenesis in vitro. The study
involved the hormone-free nutrient mediums (MS, ½
B5, ½ LS) for growing microcuttings from preliminary
obtained aseptic plants. Plant morphogenesis was
observed on the 15th and 30th days. At that, the number
of developed shoots, plant height, leaves number,
rhizogenesis rates, root number and length were
estimated. MPA appeared to have the regulatory effect
on morphogenesis of potato microcuttings. Based on mineral composition of the nutrient agar medium for
potato microcuttings growing, MPA at 100 mg/l
concentration induced root development (½ B5
medium), reduced height of shoots (MS medium),
while the number of leaf blades was not affected
The study concerns the results of the study of
coenopopulations of the following Fabaceae species:
Medicago falcata, Oxytropis candicans, and
Onobrychis arenaria under conditions of the Middle
Lena River. The study was conducted in Yakutsk
vicinities, 13 km north-east of the city. It is stated that
all the studied coenopopulations are normal. Rather
small values of substitution and recovery indices
evidence certain problems in self-maintaining
processes. The age structure analysis using two age
indices, “delta” and “omega”, allows to classify the
coenopopulations of Medicago falcata, Oxytropis
candicans and Onobrychis arenaria in phytocoenoses
of the Lena River valley as normal young populations.
They were prevailed by juvenile, immature, virginile,
and young reproductive plants
We have presented information about species diversity
of the coastal zoobenthos in some of Karasun lakes,
Krasnodar. We have shown methodology information
and reported the research area. We have made a
taxonomic analysis. The biomass and the quantity of
the main zoobenthos groups were calculated. Based on
the two main fodder objects - Olygochaeta and
Chironomidae and the P/B coefficient, there was
calculated zoobenthos production of the studied lakes.
The potential fish capacity was defined
There are three main growth points of modern information technologies: global network and mobile communication, advanced human-machine interfaces, intelligent technologies. As it is known, the system (synergistic) effect is usually observed in multidisciplinary and interdisciplinary researches. This means that an interesting direction of research and development is located at the overlap of these three promising areas, namely: advanced interfaces in the global mobile networks, advanced intelligent interfaces and the application of artificial intelligence technologies in the Internet and mobile communications. In addition, a particularly high relevance goes to the development and application prospective of intelligent interfaces to the Internet and mobile communications. The Internet intellectualities gradually, it turns from non-local storage of large data (big data) in information space that contains meaningful big data, i.e. "great information" (great info), and then in the space of knowledge or "cognitive space" in which most information is actively used to achieve goals (management) and turns into the "great knowledge" (great knowledge). There are more sites devoted to artificial intelligence, free databases for machine learning (UCI, Kaggle, and others) and even on-line intelligent applications, and interfaces used in the Internet are improving. Recently, there was an acquisition of company Oculus, which is the world's leading developer and manufacturer of ammunition of virtual reality by the developer of one of the first global social networking Facebook - Mark Zuckerberg. However, students and scientists still do not notice that open, scalable, interactive, intelligent on-line environment for learning and researches already exists and operates, based on automated system-cognitive analysis (ASC-analysis) and its programmatic Toolkit – intellectual "Eidos" and the author's website. This article is an original presentation and it is designed to familiarize potential users with the capabilities of this environment

Numerous studies confirming the effectiveness of the
use of the ozone-air mixture in various fields of
agricultural production lead to an increase in demand
for devices that generate ozone. With the increase in
demand, the requirements for these devices also
increase. Requirements from customers can be
combined in the following series: mobility, ease of
operation, ability to smoothly control performance.
The solution of these tasks is an important scientific
and technical task. This article describes possible
options for power supplies for ozone generators, and
offers a power supply circuit with the ability to adjust
the frequency, the duty cycle and the amplitude of the
signal arriving at the discharge gap of the ozonizer.
Using this scheme will reduce the mass-size
indicators of the ozonizer, thereby increasing its
mobility, in addition, it will be possible to accurately
regulate its performance and improve efficiency. If
necessary, with the help of the proposed scheme, it is
possible to introduce the ozone generator into the
electric resonance mode, which will allow obtaining
the maximum productivity of the ozonator. Thus, the
ozonizer, equipped with the proposed power scheme,
can be used in various technological processes of the
same enterprise
The article considers the model of granulometric
composition of foundry dust. We used the method of
