Novoafonskaya cave is located in Abkhazia. It is
equipped for visits in 1975. The cave has permanently
installed lighting. In caves with artificial lighting, a
vegetation of cyanobacteria and algae, bryophytes and
ferns can be found around lamps. The development of
lampenflora is a typical problem for cave management.
We have identified 69 species of phototrophs in
Novoafonskaya cave: Magnoliophyta 2 species,
Pteridophyta 6 species, Bryophyta 11 species,
Cyanobacteria 34 species, Bacillariophyta 9 species,
Ochrophyta 2 species, Chlorophyta 5 species. The
article considers main habitat of lampenflora and gives
their characteristics. We have also revealed
predominance of cyanobacteria in the cave
The article presents the results of the research on the
effect of processing cuttings grapes Moldova and
Bianca by a growth regulator called Stimolant 66f
(Stimolante 66f) on their regenerative properties, the
yield and quality of seedlings. In Moldova grade, we
tested three concentrations of the drug - 0.001; 0.01
and 0.1% and grade Bianca - five - - 0.001; 0.005;
0.01; 0.05 and 0.1%, compared to treatment with IAA
(standard) or without treatment (control). It was found,
that both types of processing cuttings with IAA led to
the inhibition of blooming buds. Application of
Stimolanta to both varieties accelerated blooming
buds, and to the greatest extent on grade Bianca. On
the variety Moldova, the processing cuttings with
heteroauxin and Stimolant at 0.01 and 0.1% had an
inhibitory effect on the growth of shoots, which
survived to the end of the experiment. On the variety
of Bianca, both the IAA and Stimolant at all
concentrations of working solution contributed to a
significant increase the length of the shoots. At grade
Moldova, basal ends of cuttings treatment for 24 hours
in solutions of Stimolanta at 0.01 and 0.1%
concentration had the root-growing ability stimulated,
enhanced the yield and quality of seedlings. In grade
Bianca, better rooting of cuttings with 3 or more roots
was observed in the variant of "Stimolant - 0.05%",
and a greater number of roots were produced in the
version of "Stimolant - 0.1%." In cuttings of varieties
ofMoldova, Stimolant showed better results than the
IAA in optimal concentrations, and grade Bianca had
about the same results

The article shows that for the essential oil industry of
the Russian Federation to solve the problems of import
substitution it is urgent to develop effective technology
to extract fatty oil from the crushed and deprived of
ether by water vapor coriander fruits. The existing
technologies for obtaining fatty oils from deprived of
ether coriander were considered. It is shown, that at
small-scale enterprises it is most advisable to remove
fatty oil by screw pressing. A brief analysis of main
factors affecting the completeness of oil extraction in
screw presses was carried out. The conclusion about
the necessity of preparation of deprived of ether
coriander for extraction with the purpose of increasing
the yield of fatty oil was made. It is shown, that one of
the stages of such preparation is the removal of part of
the shell from deprived of ether coriander, which also
increases the nutritional value of the oilcake.
Fractional composition of deprived of ether coriander
after extraction of essential oil by water vapour and
drying was investigated by sieve analysis method. On
the basis of obtained data, prior to separating the shell
by pneumatic separation, it is recommended to
separate deprived of ether coriander into three
fractions by size – coarse (riddling from the sieve with
the diameter of 1.8 mm), medium (riddling from the
sieve with the diameter of 1 mm) and fine (undersize
from a sieve with a diameter of 1 mm). Component
composition of the coarse fraction of deprived of ether
coriander was studied. It was found, that the content of the shell in this fraction is 36%, which indicates the
possibility of its effective separation by pneumatic
separation
The article investigates a fractional composition and
quality indices of industrial raw materials of coriander
in the North Caucasus economic zone of cultivation. It
was found, that losses of essential oil in raw materials
associated with the splitting of the fruit reach 23.4 %.
Essential oil from split fruits is enriched with valuable
components - linalool, geraniol, geranyl acetate.
Changes of the component composition of essential oil
from split fruits cause the following changes of
organoleptic and physicochemical quality indicators in
comparison with the oil from whole fruits: color from
almost colorless intensifies to a pale yellow; in a spicy
oil smell, similar to the smell of linalool, there appears
a more intense shade of geraniol and geranyl acetate;
acid degree value in oil from fruitlets and fruitlets
without the shell increases, respectively, by 38.5 %
and 65.4 %; ether index increases by 19.2 % and 97.5
%, respectively. It is recommended to use oil from
split fruits to correct the composition of coriander
essential oil in order to increase the content of linalool
with a simultaneous decrease in the content of
undesirable components – hydrocarbons and camphor,
or, preferably, to separate valuable components –
linalool, geraniol. It was proved expedient to separate
split fruit factions during the post-harvest treatment,
with their primary processing and intended use of the
obtained essential oil
The goal of the study is to research time characteristics

multicarrier communication systems of MC-DSCDMA,
that allows low hardware requirements and
able to operate in low quality channels. The way of
achieving this lies in using a mathematical model of
algorithm. The achieved results show suitability of
MC-DS-CDMA-signals optimization for pseudo-noise
sequence acquisition efficiency increase. The achieved
results can be applied in MC-DS-CDMA
communication systems development
This article utilizes wavelet analysis, a relatively new
mathematical tool, designed to develop an algorithm of
analysis for electrical transients in electric power
systems. Techniques, which are currently used, fall into
two main categories: time domain or the integral
transform domain. Both of the aforementioned categories
can be stressed when solving equations with a wide
spectrum or when a system of equations is subjected to a
nonstationary forcing function. One of the benefits of
wavelet analysis, however, is the ability to resolve
nonstationary nature signals easily. Based on the discrete
time domain approximation, the system components such
as resistor and inductor are modeled in discrete wavelet
domain for purpose of transient analysis. The method can
be implemented by any kind of orthogonal wavelet
transform. Computer simulations verified the
effectiveness of the proposed method. The proposed
algorithm can be implemented to calculate the shortcircuits
in electric power systems
