The article presents the model of the large-scale clustering
of the matter in the universe. The base for mathematical
calculations is interval mathematics
The article presents the problem of spanning trees with
topological criteria and interval scales. We have
introduced relationship preferences and
incomparability to find the complete set of alternatives
in the case of interval scales. The base for
mathematical calculations is interval mathematics
The article includes analysis of illegal publications, issued by the Siberian formations of the Party of the socialist-revolutionaries in 1901-February 1917, designated members of the party. The attention is given to their number and the ideological orientation
The research purpose was estimate of the red oak
growing suitability in Mari El Republic. To achieve
this goal we investigated experienced 44-year-old red
oak plantation at the Botanical garden-Institute,
determined acorns morphological characteristics of red
and English oaks and seedlings grown from them. The
evaluation of red oak plantings identified excess of
average height and tree diameter in comparison with
English oak, but the sanitary condition of both oaks
forests was weakened due to the influence of the
complex of unfavorable factors. Morphological acorns
evaluation showed that the shape factor of acorns of
English oak is equal to 1.64, while the red oak is 1.1.
Biometrics parameters of red oak bareroote seedlings
in the field were higher than English oak bareroote
seedlings. In greenhouse biometric parameters of red oak container seedlings had not excess. According to
this research, red oak is recommended for use in
landscape construction in Mari El Republic
The results of introduction test of species and cultivars
variety of irises in the Central Yakutia are described in
this article. Climatic conditions of the introduction
region are extreme and they are strong restrictive
factor at introduction to the culture of many other
species and cultivar of decorative plants. The condition
of plants after rewintering was estimated on a 4-mark
scale. Total number of the plants which were lost in
the first winter (0 points) is 126 species and cultivars
that is 60,9%. For 01.06.2015 year a collection of
irises in Yakutia makes 40 exemplar of species (22
species) and 31 exemplar of cultivars (30 cultivars), 7
species of them are successfully adapted (3 points)
(Iris biglumis Vahl., I. bloudowii Ledeb., I. potaninii
Maxim., I. scariosa Willd., I. setosa Pallas ex Link.,
I. tigridia Bunge, Pardanthopsis dichotoma (Pallas)
Lenz). The listed species annually plentifully blossom,
form seeds and intensive form escapes. Four species
Iris biglumis, I. scariosa, I. bloudowii, Pardanthopsis
dichotoma are form stable self-seedling
Clonal micro-multiplication – is this the basic method
of obtaining the qualitative virus-free planting
material. The high quality specificity of the explants
reaction of the grapes varieties to the composition of
nutrient medium requires the individual selection of
the medium components for the most successful multiplication
in vitro. In the article we present the results
of studies on the cultivation of the grapes apexes
in vitro the modified medium with the reduced
content of macrocells. As a result of conducted investigations
we have established that for the grapes varieties
of Academic Trubilin, Artemis, Gurman
Kraynova, Maria Kallas, Nizina, Petit Verdo and
Traminer Black the most effective introduction into
the in vitro culture (acclimatization of apexes 80-
100%) occurs on modified nutrient medium to
Murasige and Skoog (1962), by being differed in
terms of the content macro-elements (mG/l):
NH4NO3 – 1237; KNO3 – 1425; MgSO4 ·
7N2O – 277,5; KN2PO4 · H2O – 277,5, of the
vitamin Of v1 – 10,0 mG/l, nicotinic acid – 4 mG/l.
Remaining varieties of Kishmish luchistiy, Preobrajenie,
Roshfor K and Yubiley Novocherkasska in the
same medium were developed slowly and in a different
way
In this article we present information on features of
microcloning in culture of in vitro of perspective for
Eurasia, pink and white-berry table genetic grades of
grapes by I. A. Kostrikin, V. N. Kraynov and V. V.
Zagorulko. Researches were conducted at an input
stage in culture of in vitro of meristems of 0,1-0,2 mm
in size. At the majority of grades and forms, we noted
good regeneration abilities in the conditions of sterile
culture. It is bound to the fact that almost all the
studied grades: Anyuta, Bogatyanovsky, the Princess
Olga, Preobrazhenie, Anniversary of Novocherkassk,
Favor are received from crossing of couple the Mascot
× Sultana-ray grape. And only grades called Libya and
Lowland which showed lower regeneration properties
at stages of proliferation and rooting of shoots are
received from crossing the couple of Flamingo ×
Arkadya and (Talisman x Tomaysky) respectively. At
the same time, the grade of Talisman, being one of the
parents of the majority of the studied grades, showed
stable results at all stages of cultivation
The flora of Yakutia is rich in medicinal plants. Many
of these plants are not still studied totally. The species
Rhodiola (Crassulaceae) is one of the most popular
family which are widely used by the local population
for therapeutic purposes. Medicals use the rhizome and
roots of Rhodiola rosea as a source of medicinal raw
materials. This means the removal and destruction of
plants. The procurement should be carried out solely
on the basis of plants grown in culture because of the
rarity and few natural reserves of the species. R. rosea
L. passes a full cycle of the sprouts, blossoming and
bearing fruits during the introduction in the conditions
of Central Yakutia. The weather conditions of the year
influence on the rate of development and growth
processes very strong. The experiments determination
of the germination of local reproductions were
negative. The sprouts grow very good. In this case, it is
good possibility of intense vegetative reproduction of
Rhodiola. The evaluation of stability of introduction
may be attributed to the kind of group stability. The
great potential and adaptive capacity of R. rosea
significantly enhances the possibility of growing this
species under conditions of the Central Yakutia. It is
recommended to improve and elaborate of protection
of natural populations and unique plant communities
There were developed some methods of sterilization and introduction of the following endangered species of Caucasian flora to in vitro culture: Campanula sclerophylla Kolak., Lilium caucasicum Miscz. ex Grossh., Daphne woronowii Kolak., Pancratium maritimum L.. The effect of different plant hormones as well as their combinations and concentrations on the regeneration, growth and development of plants is studied. As a result of clonal propagation, more than 100 plants of Campanula sclerophylla Kolak, about 30 plants of Pancratium maritimum L., and 150 samples of Lilium caucasicum Miscz. Ex Grossh are saved in tissue culture
The article presents the results of studying of prospects
of use of the relative screw and combined drums in
agro-industrial complex. The developed and approved
classification of the relative screw and combined drums
has been shown in expanded form. The kinds of the
equipment on the basis of the relative screw and
combined drums making a rotary motion in which the
oscillating motion with a big amplitude, only at the
expense of an original spatial form of their internal
surfaces is reported to subjects of processing are
presented. In such devices, there are no vibroactivators.
Equipment samples in which the relative screw and
combined drums aren't rotated are also presented. They
are fixed elastically on the bed and are supplied with
vibroactivators. During the operation of the
vibroactivator, processing subjects in such cars, as a
result of the circulating movement in the relative screw
and combined drums in the planes, perpendicular axes
of their symmetry, receive the additional movement
from the walls of drums of various geometrical forms
inclined to each other
