The research was done on the basis of 47 CТ of TMJ of subjects with the orthognathic occlusion without any pathology of TMJ. The measurements of parameters aquired by CT of TMJ were taken by the personal computer with the use of the program EzImplant-Dental3D-Professional. Position of mandibular axis concerning orbital area is characterized by strength, but concerning the area po-po (external auditory meatuses) position of mandibular axis appears more variable. Received issues confirm existence of imprecisions by the use of face bow, which is aimed for transferal of models of jaws in articulator, what influences accuracy of articulator’s operation in the long run
Considered theory of termofluktuacion strength of solids. Formulas for predicting long-term strength limits. Set the value of a safe low voltage of compression depends on the physical and mechanical
material constants. For a number of technical glass received the numerical estimation of compressive stresses safety.

One of the factors of the destruction of the bonds of grain with the hit when threshing the bread mass with a shock-vibrating threshing device is the impact of the roll edge on the bread mass. The very word "blow" without a clarifying supplement can have various meanings associated with various branches of science. Its meaning expresses the idea of a sudden fact; although in different branches of knowledge it is not identified. We have considered only certain aspects of the physical impact associated with the impact of the working organs of machines and the material being processed. The article presents a study of the impact pulse of a threshing device on bread mass. To reveal the essence of phenomena when a working organ is impacted by grain, a graph analytical method is used. Dependences allowing determining the impact pulse of the milk roll edge on the bread mass, geometric and kinematic parameters of the threshing device are obtained, and also can be used to determine the energy costs
Since the industrial revolution a huge amount of pollutants
emitted annually into the water most of which is
occupied by toxic metals. These metals widely distributed
in the environment and of accumulation of a
threat to human health. It is known, that cadmium and
zinc at high concentrations have a negative impact on
nature. In modern wastewater treatment technology we
widely use polymeric sorbents with chelating properties.
The use of polymeric chelating sorbents (PCS)
usage allows separating individual or group trace elements
from large volumes of solutions of complex
composition, lowering the limit of detection, eliminating
or reducing significantly the impact of macrocomponents
which increases the cleaning efficiency.
The article presents the results of a study of conditions
of interaction of zinc (II) ions and cadmium (II) with
PCT - polystyrene-azo-o-phenol-azo-rhodanine. We
found the optimal values of the conditions for zinc (II)
ions and cadmium (II) sorption. We investigated the
effect of interfering of the macro- and micro- water
components with the sorption of the ions studied.
Maximum desorption of metal ions is achieved by
washing the concentrate with 10 ml of 2M hydrochloric
acid. The data indicate availability of the investigated
sorbent for concentration and separation of zinc
(II) ions and cadmium (II)
The urgent task facing the agro-industrial complex is the improvement of storage methods for agricultural products and the development of new ones. One of the actively cultivated crops, characterized by a variety of species, valuable taste and medicinal properties – grape. It is possible to provide the population with fresh grapes of high quality through the introduction of effective storage technologies that reduce losses, preserve marketable properties and biological value. One of the effective ways to preserve the quality of grapes during storage is the use of sulfur dioxide (SO2). This gas inhibits oxidative enzymes in berries, thereby reducing the rate of development of the phytopathogen Botrýtis cinérea, which causes gray rot. At the same time, it is especially important to control the rate of release of sulfur dioxide, since at the beginning of storage it is necessary to ensure the receipt of a large amount of it, which will eliminate Botrytis spores present on the surface of the berries and stabilize the existing damage. Further, during the entire period of storage of grapes, sulfur dioxide must be supplied in minimal quantities. Such dynamics of SO2 emission can be ensured by the use of two-phase generators of sulfur dioxide. The article investigated the effects of sulfur dioxide generators on the quality of grapes during storage. The study also investigates quality indicators of grapes of several varieties zoned in the Krasnodar region under long-term storage
