The object of the study was the sweet pomace of red
varieties of grapes grown in village Taman Temryuk
district of the Krasnodar region. By grinding in a
laboratory mill and drying in a drying oven at a
temperature of not above 60 ºC, a powder is obtained
from the mash. Its quantitative chemical analysis has
been carried out. The mobile forms of metals and the
total content of metals are determined. The content of
mercury, lead, arsenic does not exceed the permissible
levels of the maximum content of toxic elements in
flour confectionery products. The influence of powder
from grape pomace on the quality of the finished
product and on the properties of the pastry test was
studied, as the control sample was chosen the recipe
for the sugar cookies "Carrot". A part of the flour was
replaced with grape-dried powder in amounts of 1 %, 2
%, 5 % of the mass of wheat flour of the highest grade
in the test. The recipe of sugar cookies with the
addition of powder from grape pomace and without,
calculated on 200 g of finished product, and
organoleptic parameters of the finished biscuit is
given. It is established that the use of grape-dried
powder allows to increase the mass fraction of dry substances and to reduce the mass fraction of sugar in
confectionery products, as well as to enrich them with
mineral substances, microelements, which are
necessary for normal functioning of the organism.
Biscuits with the addition of powder from grape
pomace are a good source of ballast substances
reducing caloric content, which contributes to the
removal of harmful substances from the body:
cholesterol, heavy metal salts, etc
The article deals with the application of the theory of

The article considers a combination of the process-based and systematic approach in the management of OSH at the enterprise for the development of the OSH management system model. The OSH management system is created by the enterprise based on the model provision, the branch requirements and recommendations of the current standards. Features of the system are determined by the state of the external and internal environment of the enterprise (context). The context forms the basic requirements for the inputs of the system and determines its capabilities. An analysis of the context of the enterprise makes it possible to identify the system: describe its inputs and outputs, identify key stakeholders and consumers. Based on this analysis, a model of the OSH management system is suggested, which, in analogy with the modern model of the quality management system, allows us to identify the place of the OSH in the context of the organization, and also to clarify the interaction of the main groups of OSH
The article presents a study of types of expert systems
(ES) and methods of their construction. We have

Improvement is offered for working bodies’ forms in
devices for preparation of forages by methods of
engineering geometry and computer graphics. That
opens not only great opportunities for intensification,
increase in productivity and efficiency of the
technological processes, but also opens ways for
creation of small-sized devices for their realization.
Constructive study of geometry of working bodies
surface, allows us to give wavy movement to particles
of forage and impart them the movement with bigger
power consumption. In such installations forage
particles components, meeting walls of working body,
change their direction and, meeting other portions of
particles of forage components, mix up. From loading
to unloading, throughout the installations working
body length, flexible and strong waves of forage
particles components movement inside the working
body are born. The conducted pilot studies have
shown that as a result of working bodies’ forms
improvement of devices for preparation of forages by
methods of descriptive geometry such devices can be
implemented in a variety of industries
In automatic devices, relay-contact circuits are widely used. The development and description of such schemes is quite a challenge. It is known that the apparatus of algebra of logic can be used with success here.
In the article the description of the elevator movement scheme is considered first in the usual way (as it is customary to describe in the instructions), then by the formulas of mathematical logic. A mathematical description of the movement of the cabin of a passenger elevator in the form of a logical function has been obtained
At present, electrochemical analysis methods are increasingly used to solve the problem of research on quantitative and qualitative indicators of organic substances. One of the most common electrochemical methods of analysis is conductometry. Along with the straight line, indirect conductometry is often used, in which the substances under analysis react with the corresponding components before the measurement, and the fixed change in electrical conductivity is determined exclusively by the presence of the products of the reaction that occurred. A necessary condition for the application of this method is the presence of ions in the reaction medium, and since the pectic substances are polyelectrolytes, this condition is met, which allows us to use the conductometric titration method to determine the quantitative and qualitative characteristics of pectic substances. The technique we propose relates to technical biochemistry, namely, to the determination of the amount of pectin substances in plant raw materials. We have prepared "standardized" solutions of fractions of pectin substances. Samples of solutions of fractions are taken. Saponification of fractions of pectin substances in the samples of the solutions under analysis is carried out with 2.5 ml of 40% NaOH solution. Fractions of the pectin substances are precipitated with 2.5 ml of concentrated HCl. The solutions to be analyzed are centrifuged in 50 ml test strips at a rotor speed of at least 5000 rpm for 5-7 min. Suspensions of pectin fractions with distilled water are suspended in a beaker for titration with a magnetic stirrer for at least 30 minutes. Conductometric titration of suspensions of precipitates of fractions of pectic substances is carried out with stirring. Based on the results of conductometric titration, graphs are plotted, according to which the volume of titrant consumed for titration of pectic acid is established. Calculation of the mass fraction of fractions of pectic substances is carried out according to the formula. The methodology is distinguished by the simplicity of implementation, which makes it possible to obtain accurate data at high convergence of parallel analyzes, and it saves labor and time costs at all stages of the process

In agriculture, the high reliability of electricity supply is necessary because of its main feature production is associated with biological objects. The change in the state parameters can lead to a sharp decrease in the productivity of the biological system or, in general, to the death of it.
