The article gives the description and the algorithm of
the simulation model SMDS "Potok" 1.0, designed to
calculate the parameters of distribution and
sedimentation of technological alluviums in
watercourses. The relevance of the simulation model
is due to the need to determine the integral indicators
(the volume of water flowing through the areas of the
plume with a predetermined suspension
concentration, the average layer of the silt, the
specific density of the bottom silt in the calculated
zone) when calculating the harm to water biological
resources from the implementation of various
economic activities in accordance with the
methodology of calculation of damage caused to
water biological resources approved by the order of
the Federal Agency for Fisheries No. 1166 of
25.11.2011. Usage of the simulation model of SMDS
"Potok" 1.0 will increase the reliability of
calculations in determining the damage to water
biological resources, as well as bring the calculations
of parameters of distribution and sedimentation of
technological alluviums in watercourses in
accordance with the current regulatory legal acts of
the Federal Agency for Fisheries
We have studied the germination and the nature of germination of seeds of 20 species of FAM. Rosaceae. A wide range of germination characterizes their seeds: rapid, slow, with very poor or no germination. Laboratory germination of seeds stored at room temperature for 6-7 months have 80-100% - 8 species, 66-77% - 3, 1-9% - 4 species and 5 species did not germinate at room temperature, they need special conditions for germination
The article presents data on the growth of an
assimilation apparatus of Scots pine, silver birch and
pedunculate oak in the conditions of the Lipetsk
industrial center. It is established that the growth
dynamics of annual and biennial needles of Scots pine
under pollution is higher compared to the control,
while absolute values of length and mass of needles
less. Starting from the second year, in the conditions of
contamination noted stunted pine needle growth,
which increases by the third year. It is shown that the
linear dimensions of the lamina of birch in the
conditions of pollution are not changing much
compared to the control, whereas the linear dimensions
of the lamina of pedunculate oak in the conditions of
pollution is less than the control
The article presents the data about flora and vegetation of
the territory of the Yakut Botanical garden, where an
ecological trail will be; there is a characteristic of plant
communities and their classification. Preliminary, the
flora of the ecological path includes 310 species of
higher vascular plants belonging to 54 families and 172
genera
The article provides information about phytochemical
investigation, medical and nutritional importance of
fruits of Capparisherbacea L. including
CapparaceaeJuss. family in the area of the Nakhchıvan
Autonomous Republic. Some solvents had been applied,
fruit and leave extracts had been bought. The
purification and identification of content of plant
extracts had been investigated with spectroscopic and
chromotographic methods. The saponins, carotinoids,
chlorophyll pigments and flavonoids had been revealed
in the content of extracts. The extracts have been
acquired from fruits of this species by use of polar and
nonpolar solvents and the composition of extracts have
been studied with different applied methods. The
column and thin layer chromatography carried out in
order to purification of contents and extracts were
fractionation and Rf values were calculated
The review examines research unusual properties of
RNA. RNA has the ability to act as both genes and
enzymes (ribozymes). This property could offer a
way around the «chicken-and-egg» problem: genes
require enzymes; enzymes require genes.
Furthermore, RNA can be transcribed into DNA, in
reverse of the normal process of transcription. These
facts are reasons to consider that the RNA world
could be the original pathway to cells. The general
notion of an «RNA World» is that, in the early
development of life on the Earth, genetic continuity
was assured by the replication of RNA and
genetically encoded proteins were not involved as
catalysts. There is now strong evidence indicating
that an RNA World did indeed exist before DNAand
protein-based life. RNA has multiple functions.
Among these, "messenger RNA" carries genetic
information from DNA to protein formation. RNA is
often a single-stranded spiral, but also exists in
double-stranded form. In 1998, Craig Mello and
Andrew Fire discovered through their studies of the
roundworm C. elegans a phenomenon dubbed "RNA
interference". In this phenomenon, double-stranded
RNA blocks messenger RNA so that certain genetic
information is not converted during protein
formation. This "silences" these genes, i.e. renders
them inactive. The phenomenon plays an important
regulatory role within a genome. Recent years have
been perhaps the most fruitful period yet in terms of
research in the area of mRNA stability (Phenomena:
Gene Silencing; RNA interference; Identity of
mRNA decay in vivo and in vitro). The elaboration
of new methods in biothechnology have been
presented
Researches were carried out on three-eyed cuttings of
stock of phylloxera-resistant grape varieties
Berlandieri×RipariaCober 5BB (Cober 5BB),
Riparia× Rupestris101-14 (101-14), Berlandieri ×
RipariaСО-4 (СО-4), Gravesak and RSB. Cuttings of
presented varieties were wetted during 24 hours in
water and after preliminary drying of the surface were
covered in the upper part with antitranspirant, under
the temperature about 90°С. Then 40 cuttings of every
variety were placed with lower ends for 24 hours in
0,01% heteroauxin solution or for 8 hours in 1%
Radix Plus solution. Cuttings of the control variant
were placed in water. After treatment cuttings, were
couching in a film greenhouse on a heated rack in
humid steamed sawdust. In the result of the present
researches there was determined that the wetting of
basal ends of cuttings of stock phylloxera-resistant
varieties in 1% Radix Plus water solution plus during
8 hours leads to the essential activity of regeneration
processes in them. The expansion of the length of
shoots on rooted cuttings of the experimental variant
amounted for 19,2–154,5 %, the rooting of cuttings -
23,3–76,7 %, the output of cuttings having at least
three roots – 33,0–78,1 %, the number of calcaneal
roots– 80,8–257,1 %. The maximum increase of the
length of shoots under the influence of Radix Plus was
observed at varieties of Gravesak and СО-4, the
rooting – Cober 5BB and CO-4, the amount of
cuttings at least three roots and average amount of
roots on them –101-14 and Cober 5BB. The Radix
Plus caused the great stimulating influence the rootforming
ability of cuttings of stock varieties than
heteroauxin, the standard stimulator of root-forming
The article is devoted to visual analysis and its application in the selection process. New possibilities of application of visual display of information in the research process are considered. We have presented the examples of the use of visual phenotyping in breeding, evaluated the advantages and disadvantages in this area. In particular, the algorithm of the program of LHDetect for estimating leaf pubescence of wheat wafers is described, based on the analysis of digital images of the sheet bend. We have also considered Phenotiki platform that uses digital images of the profile of plants for visual phenotyping to assess plant growth. Based on the analysis of various studies it was noted that the application of visual analysis for some purposes is very effective, but for others, on the contrary, not effective. We highlight the actual problems of proper representation and converting information. The article shows the various causes of loss and distortion of data, as well as possible solutions to these problems. The work describes the application of ASK-analysis in the selection process. As an example, it describes the evaluation of the polymorphism of variety groups of grapes. We have presented interesting solutions and ways to minimize distortion and loss of information in the process of its transformation found by the authors of these works. The article reveals the concept of "computational biology" and describes fundamental differences from other areas as well as tasks, problems, possible research areas and promising directions of development of computer biology
The work was done in the research laboratory of the
department of Biotechnology, Biochemistry and
Biophysics of Kuban State Agrarian University, the
aim of which was to select the most appropriate
nutrient medium for maximum growth of lactic acid
microorganism growth. The object of the study was its
own microflora of gastrointestinal tract of quails ‒
Lactobacillus agilis, Lactobacillus intermedius and
Lactobacillus salivarius. As a nutrient substrate there
were used 4 of the nutrient media: the medium for
lactic acid bacteria (city Uglich), the melasse-autolysis
medium, the glucose-peptone medium and the MRS.
During the cultivation of the microflora of the variable
parameters were the time and temperature of
cultivation. During the cultivation of microflora the
time and the temperature of growing were the variable
parameters. In the process of growing there was
carried out the analysis of dynamics of consumption of
reducing substances and titers of microorganisms. According to the results of growing of microbial
cultures there was revealed the active consumption of
carbon substrate in used variants of nutrient media,
and it was found that there was observed the maximum
of cells to 24 h of cultivation. On the basis of carried
out results of cultivation on different media and at
different parameters there was determined that the
most titer of cells was reached to 24 h at the
temperature 38,0 °С on the melasse-autolysis medium.
So, the melasse-autolysis medium can be
recommended in production conditions as the cheaper
substrate at the further development of biological
preparations for poultry breeding
