This article studies the influence of various methods of thermal, acoustic and electromagnetic exposure on free lipid content, acid and peroxidation number of oil in sunflower seeds during their after harvesting ripening. We have investigated the influence of traditional and microwave heating on lipase activity of seeds. We
have also founded the most efficient conditions for the rate and the temperature of microwave heating of freshly harvested sunflower seeds and determined their effect on the rate of drying
In this article we have investigated fatty acid composition of oil made of flex seeds of VNIIMK-630 traditional variety and new selected SURPRISE variety. The comparative analysis of composition and factional composition of tocopherol in oil made of these seed varieties has been carried out. We studied changes in acid and peroxidation numbers when flex seeds are stored in the dry condition
The investigation results in influence of recipes components of different kinds minces on their structurally-mechanical properties are presented
The article investigates a fractional composition and
quality indices of industrial raw materials of coriander
in the North Caucasus economic zone of cultivation. It
was found, that losses of essential oil in raw materials
associated with the splitting of the fruit reach 23.4 %.
Essential oil from split fruits is enriched with valuable
components - linalool, geraniol, geranyl acetate.
Changes of the component composition of essential oil
from split fruits cause the following changes of
organoleptic and physicochemical quality indicators in
comparison with the oil from whole fruits: color from
almost colorless intensifies to a pale yellow; in a spicy
oil smell, similar to the smell of linalool, there appears
a more intense shade of geraniol and geranyl acetate;
acid degree value in oil from fruitlets and fruitlets
without the shell increases, respectively, by 38.5 %
and 65.4 %; ether index increases by 19.2 % and 97.5
%, respectively. It is recommended to use oil from
split fruits to correct the composition of coriander
essential oil in order to increase the content of linalool
with a simultaneous decrease in the content of
undesirable components – hydrocarbons and camphor,
or, preferably, to separate valuable components –
linalool, geraniol. It was proved expedient to separate
split fruit factions during the post-harvest treatment,
with their primary processing and intended use of the
obtained essential oil
In complex multiparameter technical systems there are
numerous and varied physical processes which, on the
one hand, have a significant impact on the
performance of those systems, and on the other hand, it
is extremely difficult amenable to description in the
form of meaningful analytical models based on
equations, because these models must take into
account the specific features of the systems. As a
consequence, the development of conceptual analytical
models is a "hand-made work" and it is associated with
a large number of simplifying assumptions that reduce
their versatility and reliability. But there is also another
principle of modeling: the construction of
phenomenological information models, i.e. models that
do not have analytical forms of representation that
describes the simulated system superficially as a
"black box". Such models can be built directly based
on empirical data and with the appropriate software it
can be a standard technology much faster and much
less time consuming than developing meaningful
analytical models. On the other hand, the
phenomenological information model can be sufficient
to determine the rational design features and
parameters of the modes of operation of complex
technical systems. Besides, such phenomenological
models can be viewed as the first stage in the
development of meaningful analytical models. It is
proposed to use a new universal innovative method of
artificial intelligence for creating phenomenological
models of complex technical systems: automated
system-cognitive analysis (ASC-analysis) and its
programmatic Toolkit which is a universal cognitive
analytical system called "Eidos". In the system of
"Eidos" we have implemented a software interface that
provides direct input into the system large amounts of
empirical data from an Excel file. The system of
"Eidos" can directly (based on empirical
(experimental) data) calculate how much information about the results of the technical systems is contained
in the facts of possessing certain specific structural
elements and certain values of the parameters modes
of its work. On this basis, the system provides
research-based and appropriate recommendations for
the rational choice of design features and parameters
of the operation modes of the simulated system
Article is devoted to the decision of an urgent task-
real estimation of the Internet influence on purchases, changes in economy, in connection with its wide application, concepts of electronic business and optimization of its processes.
The aim of the work is theoretical and experimental
confirmation of the possibility of improvement in
tractor unit acceleration due to the variable inertia
moment of the rotating masses of the engine. The use
of high-speed tractors in agricultural production
meets a number of difficulties associated with unsteady
processes during acceleration of the tractor
units. The emerging significant inertial loads during
acceleration result in the loss of engine power because
of what the machine and tractor unit is operating
at reduced productivity and efficiency. An analysis
of published works shows that the tractor unit
acceleration is strongly influenced by the rotating
mass of the engine. A device based on the application
of additional rotating masses in a free flywheel
connected or disconnected automatically to the main
engine flywheel at appropriate stages is offered. As a
result, the tension during acceleration is reduced.
The results of experimental studies on the effect of
the additional rotating masses on the engine acceleration
characteristics of the machine and tractor units
on the basis of Class 1.4 tractor are given. It is
proved that the use of the tractor additional rotating
mass connected or disconnected to the respective
modes of movement of a machine and tractor unit to
the flywheel of the engine, improves acceleration
performance
