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
One of important features of development of modern society is special attention world the public to problems of rationality and efficiency of use of the existing energy resources, universal implementation of technologies of energy saving and search of renewable energy resources. Gradual depletion of world reserves of oil, increase in prices for traditional motor fuels, adverse ecological situation and other factors prove the relevance of more urgent use of the available resources and works promoting development of this direction. Deterioration in a global ecological environment requires adoption of more strict requirements imposed to the fuel used in an agro-industrial complex. According to the principle of cost accounting, each entity can rely only upon itself and consume only the resources it has. It is known that fuel costs constitute a considerable part in an expense structure of agricultural enterprises. In this case, the reduction in fuel consumption can be achieved through improved processes of fuel mixing and fuel processing (fuel dearomatization, ultrasonic treatment, magnetic, electrostatic and electromagnetic processing). Bench tests of a diesel engine equipped with an experimental device for ultrasonic treatment, showed good results, confirming the relevance of the use of such devices. Devices for processing are compact enough and consume little energy, while having a sufficiently high coefficient of performance. Having small size and relative simplicity of design that does not cause complex technical issues in production, these devices can be used on virtually any type of equipment that is used for the solution of agricultural problems. The purpose of this article is to evaluate the economy of the diesel fuel when ultrasonic treatment on the example of the motor transportation enterprise
Production ecological control is an integral part of the
national environmental monitoring system. The article
describes the results of production ecological control of
impurity of groundwater drawn from wells in the
territory of the Tuapse refinery and presents a situational
plan of wells layout in the Tuapse refinery. Analysis of
groundwater was represented from 2012 to 2016 with
their content (mg/l) of oil, phenols, plumbum, chloride,
and anionic surfactants. We have revealed the excess of
oil products and phenols and developed measures to
reduce concentrations of these substances in the
groundwater refinery in Tuapse
The accumulation of free radicals in the human body
in excessive quantities is one of the reasons that are
known to cause many dangerous diseases and aging.
To reduce the negative impact of free radicals to the
body is possible through regular consumption of food
products enriched with nutritional and dietary
supplements containing natural antioxidants such as
phenolic compounds, vitamin C, vitamin E and β –
carotene. Scientists of federal state budgetary scientific
institution "Krasnodar research Institute of storage and
processing of agricultural products" have developed a
technology for production of food additives from
secondary materials generated during the processing of
apples and pumpkins. The article presents data
characterizing the antioxidant and antiradical activity
of food additives derived from secondary plant
resources developed and known technology. It is
established that the antioxidant activity determined by
the amperometric method, and the antioxidant
(antiradical) activity, determined by DPPH method,
supplements, "Powder apple" and " Powder pumpkin"
obtained by the developed technology, is almost 1.5
times higher in comparison with antioxidant and
antiradical activity of food additives, obtained by
known technologies, because of higher content of
antioxidants in the developed supplements. It has been
established that the expression of antioxidants and
anti-radical activity of food supplements obtained from
secondary resources on the developed technologies,
can be positioned in a number of (descending):
"Powder from the seeds of grapes" → "Apple powder"
→ " Pumpkin powder"
The article discusses the use of regression methods of
forecasting the deterministic time series on the example
of the load curve. Forecasts of the load curve of
electrical equipment are the demands of consumers and
their security in EPS. All predictive tasks are based on
prediction models. Electricity consumption is happening
on an electronic level; storing electricity on an industrial
scale is impossible, the consumption depends on many
random factors. Therefore, generally, we use a
combination of mathematical and heuristic models. This
is the daily task of power systems and many technical,
economic and commercial decisions on the management
regimes depend on its solutions. Development of
methods of forecasting of the energy consumption in the
system of decision-making today is one of the priority
directions in the Russian power industry. Therefore, the
work associated with the development of methods and
algorithms of forecasting of power consumption in the
power sector is still relevant
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
Analytical survey has revealed that technologies of
flaxseed oil processing used nowadays are able to
produce technical flaxseed oil if the output is high and
food flaxseed oil if the output is low. The objective of
this work is to reason the most effective method to
increase the output of food flaxseed oil while keeping
its quality high. In this article a comparison has been
made between single cold pressing of flaxseeds
without preliminary preparation with microwave
processing, as well as traditional (conductive) heating
with traditional heating under vacuum. The object of
the research is samples of flaxseeds (high quality
variety VNIIMK-620 which contains 56.28% of
linolenic acid in its fatty acid composition. It has been
established, that the use of preliminary microwave
processing enables to increase the output of oil
compared to a single cold pressing without any
processing, whereby the mass content of oil in oil cake
can be reduced by 2.2%. At the same time the
indicators of acid number and peroxide value are
increased by 0,05 mg KOH/g and 0.37 mmol of
active oxygen/kg correspondingly. Preliminary
traditional heating of seeds before cold pressing
enables to increase the output of oil, though not
considerably, compared with preliminary microwave
processing. At the same time the changes in acid
number and peroxide value are similar to cold pressing
with microwave processing. The use of vacuum when heating seeds in a traditional way does not influence
the output of flaxseed oil but enables to decrease acid
number and peroxide value to the level which is
characteristic for the oil in original seeds. Thus, it is
reasonable to use preliminary microwave processing
under vacuum before cold pressing with the view to
produce food flaxseed oil of high quality in terms of
oxidative deterioration and the increase of its output
Currently, it is important to have a solution for
problems related to the prevention of potential
accidents and the minimization of technological risks,
particularly in the oil and gas industry, the number of
accidents in which remains at a high level. Causes of
incidents and accidents at hazardous production
facilities are often non-compliance with required
technological parameters, insufficient equipment of
the technological systems with safety devices and
automated control systems of processes. The article
presents a comparative analysis of the methods that
can be used in identification of hazards at different
stages of the life cycle of the technological object:
location, design, commissioning, operation,
reconstruction. In order to develop security measures
for the selected plant, we have used a method of
analysis hazard and operability (HAZOP). The object
of the study was projected technological installation
for obtaining of bitumen with 24 thousand tons per
year performance on raw material. For the working
group of experts we have step-described the order of
research dangers of specific nodes of the process
plant, including determining the adequacy of the
protective measures provided by the project and the
development of recommendations on elimination of
the revealed deviations and to reduce the effects of
their manifestation. The most harmful deviations of
process parameters during operation of the
installation were found. We have proposed hazard criteria of operation, taking into account the
probability and severity of deviations of
technological parameters. We have also confirmed
that the HAZOP method allows not only to identify
the causes of hazards and consequences of their
implementation but also to develop recommendations
for their elimination
The role of transport in agricultural production
is significant. It is the connecting link in the
technological chain of the agro-industrial
complex (of the APC). On-farm transport in the
APC together with cars and tractor transport are
widely used. The rationality of the use of
wheeled tractors for farm transport substantiates
the possibility of their movement on asphalt and
on dirt roads. The specific gravity of the tractor
transport in the domestic agriculture is 22-27%
of the total volume of transport and 50-60% of
the volume of farm traffic. A high level of use of tractor transport has been observed in the
countries of Western Europe and the USA. In
the farms of leading countries of Western
Europe (Germany, Italy, France, etc.) about 70-
90% on-farm transport of agricultural goods is
done by tractor transport. Tractor transport in a
live environment is running on roads with
varying terrain, a wavy profile cover, on soils
with different hardness and humidity. When
driving vehicles at high speeds, the trailer is
wobbling from side to side, constantly
accompanying tractor transport during its
operation. As a result, it is bad for propulsion,
transmission, and it deteriorates the dynamic
performance properties of equipment, working
conditions of the operator. To reduce the
amplitude of oscillations of the trailer, the
operator is forced to work strenuously with the
steering wheel or to slow down the speed,
which in turn affects operator fatigue, as well as
the performance and maneuverability of the
vehicle. Thus, advanced technologies in
electronics, sensor technology and software will
determine the nature of agro-technical
innovations and will lead to increased
automation of business processes in crop
production with the aim to organize the work
more effectively, efficiently, accurately,
environmentally friendly and economically
feasible. When working with intelligent
technologies, understanding the development of
high-tech, precision engineering requires a
revision to the personnel policy and education
in agriculture, which should be based on the
relevant organization of farms and their proper
new type engineering solutions
