To reduce the development of additional settlement
strip foundations of the existing building on the effect
of pressure transmitted to a ground base located near
the new slab foundation is considered the work of the
geotechnical barrier in various ground conditions. In
the first variant of soil, conditions (variant 1) made
geotechnical barrier structure in a homogeneous
thickness of the weak clay soil. In the second variant
of soil conditions (variant 2), a separating barrier is
performed in a two-layer base. The upper base layer
(carrying) is shown a weak water-saturated clay soil,
and the second (underlying) - low compressible soil
(sandy loam plastic). According to the results of the
calculations and modeling found that, the greatest
positive effect on the separating barrier structure
(geotechnical barrier) is achieved in the case when the
base is a two-layer. The lower part of the geotechnical
barrier must be recessed into the soil of low
compressibility. Additional settlement strip foundation
of the existing building in a uniform basis (variant 1)
in the absence of geotechnical barrier is approximately
8 cm. In the case of a two-layer base (variant 2), the
additional settlement strip foundation building is
reduced by 80-85% (6.6 cm) and will make about 1.4
cm
The power plant being investigated is Novocherkassk
State District Power Plant located in the settlement of
Donskoy, Rostov region. The power object is included
in the list of objects of the fuel and energy complex
subject to categorization and is defined as critically
important. The analyzed site is the "subsidiary farm",
which includes a chemical reagent warehouse and a
site for chemical water purification, where hazardous
substances are treated: sulfuric acid and technical
sodium hydroxide. The analysis of the main causes of
accidents at thermal power stations occurred during
processing, storage and transportation of hazardous
substances, and typical scenarios of possible accidents
at the chemical water treatment plant of thermal power
plants were considered
In recent years, many pigs of specialized breeds,
characterized by increased meat qualities, have been
brought to Russia from Canada and a number of
European countries. The article presents the results of
the assessment of slaughter and meat qualities of pigs
of different genotypes. Danish pig meat was used as
research objects: purebred landrace (CHL), benthic
hybrid Landrasx yorkshire (LxY), three-breed hybrid
landrace hyorkshire x dyurok (LxXxD), removed from
control fattening, and developed prototypes of delicacy
products. The commission evaluation of meat and
broth showed that the boiled meat from the three breed
animals received the highest score, and the quality of
the broth significantly exceeded the samples of
purebred landrace and two-breed animals. As a result
of the tasting evaluation of the Voronezh ham, it was
established that the samples of meat from threebreeded
pigs, in comparison with the samples from
purebred meat, show the most pronounced flavor,
aroma and soft consistency
Excess body weight is a serious problem, involving a
set of diseases presently. For this reason, taking into
account demands of science there was a development
of production of food with the lowered energy value
for the people having first of all obesity that led to
production of substitutes. Even more often producers
resort to use of nutritional supplements, which
generally receive in synthetic way. In this article, we
analyzed multiple references and summarized the
material regarding beet fibers. As a result of numerous
researches it has been proved that food fibers make
favorable impact both on the separate systems of a
human body, and on all organism. The use of the
minor products of processing of the plant raw material
is also critical; they allow improving the preventive
properties of products and enriching them with dietary
fibers, protein, and mineral elements and also
development of food development of curative and
preventive action. Citri-Fi food fibers which are
received from dried-up orange pulp are well-known,
they can keep a large amount of water throughout
technological process. They exert positive impact on
structure of fat that gives the chance to create a
product with the lowered content of fat
The article presents the results of the study of the
effect of the size of the explant clonal rootstocks for
stone fruit crops of the Krymskaya OSS VIR VSL-1,
VSL-2, LC-52, RVL-1, RVL-7, VVA-1, AP-1 injected
in vitro and concentration vitamins and
phytohormones in a nutrient medium on the efficiency
of introducing in vitro of these rootstocks. The optimal
size of the injected in vitro explant was determined and
nutrient medium in the first stage of micropropagation
was optimized. The optimal size of the dissected
meristem, which provides the maximum percentage of
explant initiation is 0.4 mm. The modified version of
the nutrient medium based on the Murashige and Skug
prescriptions with a reduced content of vitamins B1 0.1
mg / l, B6 0.4 mg / l, PP- 0.4 mg / l, and phytohormone
6-BAP - 0.3 mg / l. at the first stage of cultivation of
explants of clonal rootstocks for stone fruit crops is
optimal. The survival rate of explants in all tested
samples of clonal rootstocks on this modified nutrient
medium was in the range of 92.5-97.5%
In peach orchards of the Russian humid subtropics, leaf curl is the most dangerous and harmful disease. Due to the high degree of danger from the peach leaf curl, for the first time in this region the main task was to analyze peach leaf curl development on weather conditions. In order to solve the problem, it is proposed to apply a new innovative intellectual technology: automated system-cognitive analysis (ASK-analysis) and its software tools - the “Eidos” system. In order to build the model, based on our own observations and the experience of Russian and foreign colleagues, it was decided to use the following factors: the sum of temperatures above +4 ° C of the current year (for the period from January to April), the sum of temperatures above +4 ° C of the previous year (for the whole year), the sum of precipitation of the current year (for the period from January to April), the sum of precipitation of the previous year (for the whole year), the number of hours of infection (in the current year). It was established that such factors as the number of hours of infection, the sum of temperatures above +4 ° C in April and during the period from January to April, as well as the sum of precipitation in March and April, are the most important in the dynamics of peach leaf curl development and spread. High rates of leaf curl spread and development are caused by the number of hours of infection in the range of 1440 ... 2064 hours, as well as by low air temperatures in March and April (the sum of temperatures above +4 °C – 89,4-240,4° and 283,7-316,7°, respectively) and high air temperatures - in January and February (the sum of temperatures above +4 ° C – 155,3-259,6° and 243,5-280,1°, respectively)
Feijoa crop is valuable due to the complex of useful
traits (high frost resistance, big yield, ornamental
value and long profitable period). These fruits have
delicate flavor, nutritional and dietary properties. The
fruits are juicy with a pleasant, gentle, refreshing
sweet and sour taste, specific strawberry-pineapple
flavor and contain significant quantities of important
substances for the human body. Pectin (up to 2.5%),
sugars (6-14%), proteins, vitamins, organic acids,
mineral salts, etc. are among them. However, the
challenge of its cultivation is the lack of cultivars and
plantations are represented by a mixture of hybrids
originated from free pollination, and characterized by
a great variety in biological and morphological traits,
differing not only in yield, but in size, shape and
yield period. In this connection, the breeders faced
the objective to create new cultivars of feijoa, using
classical and modern breeding methods and available
genetic resources for commercial gardening and
production. Development of the core hybrid diversity
material and selection of promising forms are the
most important stages of the breeding process,
providing success of further breeding programs. The
breeding of varieties and forms for crossings was
carried out according to the principle of combining
the desirable traits of the obtained offspring. There
are direct and reverse crosses in six combinations
('Dachnaya' x 'Superba', 'September' x 'Superba',
'Dagomysskaya' x 'Superba', 'Superba' x 'Dachnaya',
'Superba' x 'September', Superba ; X 'Dachnaya'). The
viability of the pollen was evaluated prior to
pollination, by germination on a nutrient medium -
1% agar-agar + 15% sucrose. The degree of fertility
varied year by year: in 2015 - 60-62%, and in 2016 -
68-77-88%. The best crossing combinations were
established 'September' x 'Superba' and the 'Superba'
x 'Dagomyskaya for the creation of the hybrid
genepool of Feijoa sellowiana. A high percentage of germination of the feijoa seeds was noted in
combinations of 'Dagomyskaya' x 'Superba' (74%)
and 'Superba' x 'Dagomysskaya' (70%).
In the conditions of middle valley of the Lena River on
the cryogenic, inundated, cespitose and chernozemic
soils different steppe communities differently react on
dietary regime. Herb-grass phytocenosis at organic
dietary regime is reformed in cereal phytocenosis with
the contents of cereals to 76% and bean types 19% of
dry basis with productivity to 20 centner of hectare of
dry basis. At the same time the efficiency of the
improved phytocenosis was on charge exchange
energy of 17,3 mega joule of hectare, feed units 1032
and a crude protein of 247 kilo of hectare. The whetgrasses
phytocenosis has provided productivity to
19,4 centner of hectare and the content of perevarimy
protein in 1 feed unit up to 118 gram. So the most
effective for the steppe meadows is using complex
fertilizer (humus of 20 tons of hectare + N60P60K60),
increasing the productivity twice with a high quality of
food
The article identifies the value of livestock in the economy of the Bryansk region; we have also given the spatial-temporal analysis state of the industry and identified the key trends in its development over the past 25 years. This work considers the geography of industries and production of major livestock products
In the world, huge work is being done to create global
information banks of plant genetic resources. The need
for conservation and rational use of genetic resources
in modern conditions has become very relevant.
Genetic collections are the basis for selection work:
creating new varieties, replenishing the assortment
with new, classic, introduced and native varieties,
adapted to the natural (soil and climatic) conditions of
the cultivation sites. In the Anapa ampelographic
collection, 4911 varieties of various ecogeographical
and genetic origin are represented, the use of which
provides great opportunities for creating and breeding
new varieties, their state testing and zoning. In the
gene pool of the ampelographic collection, most
varieties of V. vinifera L. grapes are represented by
local honeycombs of different regions of the grape
culture, and more than one fourth of varieties of V.
vinifera L. are obtained from intraspecific crossings.
Despite the value of local varieties of grapes, they do
not always meet all the requirements of production.
Therefore, to improve the local assortment, it is
necessary to carry out selection - breeding new
varieties of grapes. This article presents the long-term
results of the work on the selection of varieties of table
and technical directions in the Anapa ampelographic
collection used for breeding. Also, the role of the
genetic collection in the creation of new generation
varieties by combinative selection is shown - as
donors for creating new varieties of grapes. Dedicated
varieties are the sources of valuable traits, which are given primary importance and are especially important
for the viticulture of the Russian Federation
