The effectiveness of disinfection depends on used disinfecting materials for vans, their actions and technological parameters of the installation for applying disinfectants. Hot mist generators provide uniform distribution of particles of disinfectant solution inside the van for transportation of agricultural products. The parameters of the generator of hot mist affecting the quality of disinfection were investigated. Tests were conducted for the vans used to transport agricultural products. For studies we used the vans in operation, which transport farm animals (pigs) and had been disinfected before. Sampling for the research on contamination was performed with pre-prepared swabs. Factorial experiment was planned with using scheme #32, and as a result of significant factors in the univariate experiments we set a temperature of the aerosol disinfectant solution and the duration of surface treatment. As an optimization function we have chosen disinfection efficiency of bodies of vehicles carrying agricultural products. Comparing the results of the experiments on different groups of microorganisms we have found that the optimal mode of hot mist generator with a dispersing device are: the processing time of 1 m2 - 8.5 at the processing temperature - 65º C
The article, on a simple numerical example, deals with the application of the automated system-cognitive analysis (ASC-analysis) and its software tools - intellectual systems "Eidos" for the detection and investigation of determination of emergent macro preferences of systems in their composition and hierarchical structure, i.e. the sub-systems of various complexity levels (levels of the hierarchy). The article briefly discusses some of the methodological issues of creation and application of formal models in scientific knowledge. The system generalization of the principle of William Ross Ashby about the necessary diversity on the basis of the system of generalization of the theory of sets and systems theory, information, generalized formulation of the principle of Galileo-Einstein, the hypothesis about its relationship with the theorem of Emmy Noether are offered; and also there is a hypothesis "About the dependence of the force and direction of the relations between the basic elements of the system and its emergent properties as a whole, on the level of hierarchy in the system"
For the design of rotary-film evaporators of the
technology for food production we need summary
tables of performance parameters of the process. To
obtain them it requires a significant amount of
experiments that require a large investment of time and
resources. Therefore the actual task is reducing the
cost of designing of the technological process, due to
the choice of optimal parameters of the rotor-film
evaporator. This problem can be solved by conducting
a small series of experiments aimed at identifying
general mathematical dependences of the parameters
of the processes of evaporation on the performance of
the device. Based on the obtained dependencies it is
possible to find design and selection of evaporators.
The study proceeded from the assumption that the
maximum thickening of the initial solution in the
evaporator, it is possible while achieving the
maximum possible temperature, the filing of the
original solution in the apparatus and performance
during repeated evaporation and infusions from the
fruits of chokeberry. The calculation is performed
taking into account the prevention of adhesion of
evaporated solution on the walls of the apparatus and
the rotor blades, which may reduce the quality of the
end product. The data confirm the effectiveness of the
method of repeated evaporation on the example of
concentrating the water-alcohol extracts of black
chokeberry
The article provides a comparative analysis of two methods for assessing the structure of adhesive joint: optical microscopy and microtomography. Comparative analysis of the accuracy of measurement was shown; we have also built the graphs of the
thickness of adhesive joint. The depth of penetration adhesive into the wood was determined. The structure of adhesive joint for two types of binders was studied
The article deals with the issue of alternating irradiator installation for growing plants in protected soil. The point of the method of illuminative installation con-sists in periodical influence of relatively high irradiance upon plants against a background of constant influence of relatively low one. It reduces plant radia-tion irregularity, improves the quality of agricultural products and cuts down energy-output ratio of growing processes.
The aim of the research was to develop a geographical
information system (GIS) for monitoring soil fertility
based on calibrated remote sensing data within Rostov
region. The possibility of developing a geoinformation
system for irrigated agrolandscapes monitoring based
on modern computer geoinformation technologies for
problems solving of reclaimed territories management
in cooperation with other automated information
technologies is considered. An example of selecting
main degradation processes for the irrigated
agrolandscape within Rostov region boundaries, the
main possibilities of the system and the proposed
directions for its development are presented. To
develop a geoinformation monitoring system, the
ArcGIS 10.4.1 for Desktop software package has been
selected. Monitoring GIS includes remote sensing data
obtained from the VEGA-Science satellite monitoring
service. The technology for creating a geodatabase for
degradation processes monitoring, necessary for rapid
analysis of information and time-saving on collection,
processing and calibration of data bulk is introduced.
As a mapping principle, graduation of farm fields by
intensity of land degradation processes was used. GIS
monitoring includes multi-layer digital maps and data
attribute tables characterizing the main indicators of
soil fertility and crop seeding development. The use of
GIS technologies with satellite data will significantly
reduce the complexity of field survey data processing
by data processing automation and is promising for
developing computer monitoring systems for irrigated
agro landscapes. Farm specialists are offered a
convenient mechanism not only for data accumulation,
but also for maintaining fields’ history with reference
to the yield year. Analysis tools allow performing data
spatial and logical queries, to run samples and reports
In the article the expediency of application of ashe-ablation and claydite dust in concrete slabs and pipes widely used in the conducting grids of irrigation systems is shown
Tracking is a vast field of research associated with
navigation, robotics, and virtual environments (virtual
reality). Tracking for augmented reality requires higher
level of precision, increased range of action, as well as
work with a wider variety of input data. It is important
that augmented reality technology requires tracking in
real time, which also complicates the task. Correct
visualization of objects in three-dimensional space
requires six degrees of freedom tracking: three position
values (x, y, z) and three angles (rotation around the
respective axes) to determine the orientation. To solve
this problem, different approaches and sensor types are
being used. In this article, we present a brief history of
the development of tracking technology and analyze the
current approaches to implement the process of tracking
on mass mobile devices such as smartphones and tablet
computers. We also describe some issues in
implementing optical marker based tracking for
visualization of large scale models
Nine out of ten acts of sabotage are committed by
people one way or another associated with information
technologies. According to experts at InfoWatch,
developer of systems to protect confidential
information from insiders, the reason for this
profession lies in the psychological characteristics of
these employees. Reading more will allow
understanding the problem with a couple of examples
from the life that most powerfully illustrate typical
traits of professionals in the information environment.
And, although the first teller did not hide his name, the
second one decided to remain anonymous. Deep
psychological background of the act of sabotage often
leads to the fact that a disgruntled employee threatens
boss or colleagues, for example, by e-mail. Sometimes
he even shares his thoughts with someone from
colleagues. In other words, not only the attacker knows
the information about the upcoming sabotage. Analysts
estimate that other people know 31% of information
about the plans of a saboteur. Of these, 64% are
colleagues, 21% with friends 14% — family members
and another 14% were accomplices. It was also
determined that 62% of corporate saboteurs think
through their actions beforehand. In 47% of cases, they
commit preparatory acts (e.g., theft of confidential data
backups). 27% — design and test of the future
mechanism of the attack (preparing a logic bomb on
the corporate network, additional hidden system
entries, etc). In 37% of cases the activity of employees
can be noted: of this amount, 67% of preparatory
actions visible online 11% offline and 22% both
