The article focuses on current issue of improving the
reliability of water intake buildings in the Far North.
We have given special operating conditions of these
structures, particularly ice drift, shore ice piles, windrowing
ice fields and erosion of the bottom of the
moving ice field with keel protrusion. We have described
physiographic, structural and morphological
conditions of the construction site, generalized information
on the parameters ice drift during an ice
moving in the waters of the Gulf of Ob in Salmanovskaye
deposit area. For these conditions, we
have accepted to make water intake structure with
recessed filtering part and given idea about their ice
protection and proposed an effective design of protective
constructions for all possible effects of ice
hummocks. We have also given a description of bases
of technology of construction works the rationale
for the design parameters of facilities. In view of the
possible load, two rows of closed pile foundations are
provided for the protection of water receivers consisting
of bored piles and channel filtering grillage. In
the first row, near to the water receivers we have provided
metallic, lattice constructions from metal profile
pipes laid on the top of water receivers on the
grillage. The second row of protective structures
around water receivers was designed as a halfly indepth
monolithic reinforced concrete grillage of rectangular cross-section form with an ice pick from a
metal corner rental rendered monolithic on the outside
perimeter of the grillage. Concrete grating are
designed also to protect the gravity pipelines along
the borders. Rectangular grillages interconnected
with cross bar bonds witch are also made of reinforced
concrete. The proposed technical solutions
provide reliable protection against possible water
intake facilities including dynamic effects from windrowing
ice fields in the Far North. Options include
new constructions of underground horizontal and
channel filter water intake structures that could be
effectively used in such conditions
Eight-year research data of crop rotation of new
six-field crop rotations and energy-saving methods
of their cultivation are presented in the article. More productive grass- grain ploughing crop rotation and energy-saving means of main soil cultivation, rates
of fertilizers and regime of irrigation, increasing productivity of agricultural lands, keeping fertility
and biodiversity of irrigated agro landscapes were revealed.
The results of three years experiments of using local mineral raw materials such as bentonite clay as ferti-lizer are given in this article. Autumn bentonite appli-cation in the dosage of 10 ton/hecht has given 21,7% crop addition. Usage of N30Ph30 and N60Ph60 on this background has assured addition up to 32,6-34,1%
The results of the experiment to study the influence of aromatic additive “Caramel-Vanilla” at the killing indicators of pigs of large white breed are presented in this article. It is established that the cultivation and a fattening of pigs when adding this aromatic additive to animal feed is an effective technique. The use of aromatic additives in rhythm input: 10 days with the addition of 10 days without it until the end of fattening positive impact on feed intake, growth, and the payment of his live weight gain of pigs. The live weight of animals for the period of experiment (123 days) increased by 8.6 % compared with the control
This article presents results of trials of feed additives
called "Yoddar-Zn" and "Glimalask-Vet" to improve
quality characteristic of meat of beef cattle. It was
established that the most efficiency of these additives
was achieved when used in complex. The carcasses of
calves, which were consuming a complex of additives
"Yoddar-Zn” and “Glimalask-Vet” (I c.), contained
meat of the highest sort more than control by 6.48 kg,
the animals which consumed only "Yoddar-Zn” (II c.)
- 3.50 kg, the first-sort - at 15.19 and 7.86 kg. In
experimental groups of calves there were observed
more intense integral characteristics of meat color. The
flesh of carcasses from the calves of experimental
groups, the fat was higher than control, 0.13 and
0.07%, protein - by 1.79 and 0.97%. Animals
experimental groups synthesized more protein at 5.45
kg, or 13.70%, and 2.62 kg, or 6.59%, energy - to
304.3 MJ, or 18.17%, and 146.8 MJ, or 8.77%. Meat
of experimental animals, contained more essential
amino acids. Protein meat quality indicator was higher
than control, 0.73 and 0.28, amino acid index - by 0.17
and 0.04. The meat from calves of experimental group
had a higher culinary and technological parameters,
optimal fractional composition of muscle protein and
lipid composition of adipose tissue, better digestibility
The results of studies of the effect of different types of formation to the content of pigments in the leaves of apple trees in the central zone of Horticulture Kuban Krasnodar region. It is determined, that the content of chlorophyll «a» and «b» in the leaves is seasonal and depends on the biology class. The highest amount of chlorophyll in the leaves of apple in the autumn varieties (Prima, Gala) cultivars has been observed in August, in the winter varieties (Reinette Simirenko, Florine) - in September
The term "methodology" is understood differently. Methodology - the doctrine of the organization. Methodology (from the "method" and "logy") - the doctrine of structure, logical organization, methods and means of action. Methodology - the system of principles and methods of organization and construction of theoretical and practical activities, as well as teaching on this system. From these definitions it follows that the methodology - is an intellectual base rod defining approach to specific activities to management decisions. The methodology, which adheres to the manager, lies at the heart of its activities, determines its success or failure, manifested in the consequences of decisions. We give some examples of methodological errors which lead to wrong management decisions. So, the person who seriously requires providing "maximum profit at minimum cost" should be classified into one of two classes, which can be briefly described as "fools" and "liars". Profit must not be the sole purpose of business. The following section will discuss the methodology in place of conducting various scientific economic and technical studies. A natural continuation of the topic - the wording of some of the methodological problems using mathematical methods
The article presents the results of the studies of the use
of "Selenium-Vita" bioactive feed additive, containing organic forms of iodine and selenium, in the rations of lactating cows of Black-motley breed of Danish origin; positive influence of the tested drug on milk production and milk quality is revealed
The influence of agrochemical and physical properties of a soil on the growth of the seedlings of Pinus sylvestris in the forest nurseries in Chuvash Republic is studied. The correlations of the growth of the seedlings and agrochemical and physical properties of the soil are simulated
The original soils were investigated at the Black Sea coast of Russia. Severe degradation of the soil in a Utrish nation reserve were identified as a result of high recreational pressure. Soils with high recreational load have low humus content (2-3 times) and a lower en-zymatic activity than the control of the soil. Biological parameters can be successfully used for environmental monitoring of soil of Utrish reserve, in contrast to the chemical and physic-chemical properties
