The results of pilot research in the investigation of the effect of gouge which was formed with the scoop of the effector of the horticultural chisel plough during the row-spacing cultivation about the outline of a root age bedding on macro and microstructure of soil aggregates, the alteration of quantum indices subject to intensity and duration of culti-vation are given in this article
The article presents the results of studies of dynamic phenomena caused by the process of cutting band saw and clarified the zones in which resonance occurs, which negatively affects the overall bandsaw
The article contains the estimation of effectiveness in the use of by-products, cameline-seed oil and amaranth flour in the meat by-products in the dough. By-products were used for the purpose of the expansion of the assortment of the meat semi-finished products in the dough. Amaranth flour was introduced for the purpose of an improvement in the organoleptic and functional- technological characteristics of the stuffing and an increase in the quantity of protein. Cameline-seed oil was added for the purpose of the enrichment of product by omega- acids. As the experimental models we have made pelmeni (ravioli), the relationship of dough and stuffing in which comprised 1:1. In the prototypes the flour from the amaranth was introduced in quantity 5, 10 and 15%. Cameline-seed oil was introduced in quantity 2%. Models with the amaranth flour in quantity 5% had the smaller output of product and the insufficient moisture-binding ability. Models with the content of flour from the amaranth in quantity 15% had the strong smell of plant component. Experimental model with a quantity of amaranth flour 10% on the organoleptic characteristic proved to be best, and there composition was acknowledged most optimum. The studies of the experimental models of meat semi-finished products in the dough showed that the use of amaranth flour contributes to an increase in the moisture-binding ability of stuffing, to an increase in the output of product, to an increase in the content of protein and irreplaceable amino acids. According to the results of all conducted studies is made the conclusion that flour amaranth can be used as the moisture-binding component for making of meat semi-finished products in the dough
The events recognition problem in the field of central forces is discussed in the article. The currency forecast model based on the astronomical data is developed
Due to the mass construction activity during the recent years, many multistoried buildings with different height, shape and function have been built. Very often, such buildings are located on territories with very complicated subsoil conditions, which cause considerable total and differential subsoil displacements. Reachable variety of settlement calculation methods performs wide difference between achieved results. Thus the data of the geotechnical monitoring is very important for practical and scientific issues
The article deals with the study of the influence of the
elastic damping mechanism (EDM) on the operability
index for arable MTU on the basis of the 1,4 class
tractor. The elastic damping mechanism was designed
in order to smooth the aggregate starting, to reduce the
dynamic load in transmission, to protect the engine
from the external load vibration. The experimental
results that were obtained while full-scale field studies
of serial and test (containing EDM in transmission)
machines are given in the article. Various oscillograms
are analyzed: torque on the axis of tractor's driving
wheel, tractive effort, the speed of the driving wheel,
angular velocity of engine shaft and haulage. The
mass-spectrum analysis was carried out to study the
tractor characteristics in time more thoroughly. Such
analysis allows to evaluate qualitatively the EDM
influence. The normalized autocorrelation function and
spectrum density of variation in time are studied in
details for the following MTU characteristics: the
wheel torque, haulage and tractive effort. These
characteristics were compared with analogous
characteristics for serial MTU model. The obtained
results confirm that the EDM use in the tractor
transmission has a positive effect on the functional
MTU indexes. Obtained data can be used in
mathematical modeling of MTU functioning
The filling piles and their joint work with soil are the objects of research. The joint working of filling piles and soil has been researched with the constant rate of loading (CRL) and the continuous measuring of deformations of physical model. The experiment was realized at the physical model of filling pile in soil with the apparatus AKP-6NM. The hypothesis of mechanical working of near-pile soil was proposed as the result of the experiment
Results of engineering and scientific search of
improvement of resource-saving machine technologies
of finishing and cleanup processing of cars details,
development of new camps and technologies are
presented. The possibility of low-frequency
fluctuations with big amplitude can be implemented
due to assembling flat or curvilinear elements on
external surfaces of the relative screw reel. The use of
computer modeling enabled us to obtain a relative
screw drum that provides not only giving movement to
loading masses with a big fluctuations amplitude, but
also compression of loading masses in the process of
their motion from loading to unloading. In such
machines increase in processing efficiency is reached
not only due to achievement of great movement
amplitudes values of the loading masses, but also at
the cost of compression of loading masses in
processing and intensity increase of their mixing. The
scheme of the machine for continuous processing with
mechanization of separation of details from working
environments particles is provided. Results of
researches of quality and surfaces micro hardness
change processed in the offered machines designs
show that details processing time makes 3-6 min
The methodological, theoretical and applied aspects of making prognoses and estimation of information systems efficiency are under consideration in the paper. These ones are based on the original models of the principal constitutive of human factor, those are the preferences in the form of the matrix mechanisms of the complex estimating with the enlarged functional possibilities
The article deals with the reliability of the functioning of the equipment of the power supply substation, and the determination of the probability of uninterrupted supply of electricity to consumers. The following are presented: models of failures of separators, models of short-circuit failures, models of failures of disconnectors. Two statistical series for sudden and gradual failures are singled out. The reliability theory is shown as the main distribution of fail-safe time for sudden failures. The conclusions on the presented models are made and the suggestions on introduction into production are given. According to the presented models, it is possible to judge the reliability of the station's operation, which is necessary for implementing measures to improve the reliability of electricity supply in network companies
