Based on the analysis of the designs of feed mixers for farm animals, the option of using a two-stage mixer is being investigated. The proposed design of the mixer allows you to improve the quality of the feed mixture and reduce energy costs per process. To optimize the mixing workflow, the design parameters of the machine and their influence on the technological process under various working conditions are determined. It has been established that the design of the mixer and the initial physical and mechanical properties of the components of the feed mixture directly affect the most important technological characteristic of the installation, its performance. Therefore, the study aims to optimize the process of mixing feed

Using queuing theory (QT) for the new technology of harvesting of grain crops by the method of «Neveyka», the method of optimal designing of maintenance system and elimination of failures of units used in cleaning technology and post-harvest processing of grain has been considered. On the basis of a systematic approach, taking into account the probabilistic nature of the change of operating factors the methodical directions of validity test of the adoption of the Poisson distribution in the calculation of operating modes were substantiated to optimize maintenance level units and eliminate failures in the operation of the machines, the probability of failure-free operation of harvesting and transport aggregates. The probability of failure-free operation of each type of units used in the cleaning of grain depends on their number and intensity of service. According to the numerical value the probability of failure-free operation of units is equal to the probability of idle units for maintenance and elimination of failures. Since it is impossible to determine separately the value of the probability of failure-free operation for all types of units and all kinds of services at different operating conditions the generalized solution has been offered, this solution is applicable to any serviced unit during both the technical inspection and elimination of failures. By specifying the desired value of the probability of failure-free operation of harvesting units, according to their number we can determine the appropriate ratio between the average length of service and the average period of time between incoming service requirements (technical inspection and elimination of failures) from one unit
Numerous studies have found a different quality of the
buds along the length of the fruit arms, which expressed
various degrees establishing embryonic inflorescences in
the central buds. It is revealed that many of the grapes
have more fruit-bearing eyes formed on average (4-6
knots) and upper (7 to 10 knots) levels of fruit escape,
compared to the lower (1-3 nodes) layer. In connection
with the different quality of the buds along the length of
fruit vines should be used and different ways of cutting
them. It is necessary to consider the biological
characteristics of varieties, ways of doing and shaping
the bushes, the weather conditions of the area during the
growing season and relative calm. To receive annually a
stable high yield of grapes, we must first set the optimal
length of pruning fruit shoots and optimal load on the
Bush healthy eyes. This requires for each class on the
eve of trimming bushes to carry out the analysis of the
wintering holes along the length of the fruit shoots and
to identify the embryonic fruitfulness of Central buds,
i.e. to carry out the prediction of grape yield next year.
The article presents data on the formation of the
embryonic fruitfulness of Central buds of wintering buds
at the Taman group of grapes – Arcadia, Viorica,
Hibernal, Cabernet Sauvignon, Merlot, Moldova, Pinot
white, Riesling, Saperavi, Traminer pink, Tsimlyansky
black, Chardonnay. Found higher rates of embryonic
fruitfulness of Central buds buds in the studied grape
varieties - Chardonnay, Riesling, Viorica, Hibernal,
Merlot, Moldova, where the coefficients of fruiting
ranged from 1.40 m from Riesling to 1.69 from Merlot;
factor productivity of 1.58 from the Chardonnay to 1.77
from Merlo. The high percentage of fruitful buds from
80,8 from Cabernet Sauvignon to 95.6 in the cultivars
Merlot and Chardonnay. A higher percentage of eyes
with 2 embryonic buds in the cultivars Merlot and
Viorica who have this indicator amounted to, respectively: 75,6 and 70.6%. Forecasting a crop of
grapes next year to trim the bushes on the proposed
method will provide a full crop of grapes
A diet of a modern man affects the formation of a healthy lifestyle very highly. It supplies the body with the main and irreplaceable nutrients, mineral components and energy. The Russian Federation population surveys, which were carried out by government agencies of the country show us that there is a lack of many nutrients with high nutritional value. Russian market is gradually stuffed with food products which have high nutritional value. For the maintenance of health, active longevity, and for improving their performance, people must consume their organism with all the necessary nutrients. That's why achieving an optimal balance among the nutrients is one of the important question of vital activity. In this article, there were considered optimization approaches to human diet with considering different types of metabolism and maintain weight with using economic and mathematical methods. Also in this article you can find the calculated values of the daily values depending on your calorie eating plan, anthropometric parameters and energy expenditure. We obtained daily value of calories and distributed basic food components- carbohydrates, proteins and fats, and also we calculate the optimal diet for the results of each type of physique - ectomorph, endomorph and mesomorph
