STALLING SPEEDS OF PRESSURE IN-FLOW STREAMS OF STOCK-RAISING FLOWS, MINERAL FERTILIZERS AND WATER
DescriptionThe article describes a circular two-surface threecomponent jet agitator (pump). The calculation method of critical precavitation speeds and in-flows of livestock wastes and mineral fertilizes was introduced

Description
The article contains a scientifically based approach to assessing and improving the reliability of DMU "Frigate" in the conditions of the Rostov region. The studied parameters for the elements with the lowest resource were: mean time between failure, mean time to repair, probability of failure, the parameter flow of failures, failure rate, actual and allowable factors of readiness. The analysis of the main faults of DMU "Frigate", identified nodes and elements, characterized by the low reliability, for which the dependences of probabilities of failure-free operation, as well as the dependence and developed the procedure for calculating the optimal duration of recovery of failed elements, to ensure acceptable availability. Statistics on major faults refuse items were collected over the three irrigation seasons from 2013 to 2015, were investigated failures due to wear of the elements for 17 irrigation machines. As a result of the research we developed mathematical apparatus of calculation and the comparative assessment of the readiness of the parks sprinklers of various farms to perform their processing functions at the same and different number of machines. We obtained the dependence for determining the allowable duration of the recovery elements that will allow you to determine the main directions of improving the reliability of DMU "Frigate" during the operational phase

COGNITIVE TECHNOLOGIES FOR SIMULATING OF A SYSTEM OF IRRIGATED FARMING OF REGION
DescriptionIt is suggested to realize simulating of a system of irrigated farming by means of cognitive technologies. A cognitive map for interaction of irrigated farming system with the environment is developed. Re¬search principles for scenarios of system behavior of a simu-lation model are stated

Description
The article describes the results of flume reinforced concrete survey carried out in Azov irrigation system and gives conclusion about their condition. It shows characteristic fea-tures of destructions for the period of fifty years of its operation. There have been given aver-age indices of reinforced concrete strenth and the question about the necessity of mainten-ance-restoration work in irrigation systems is raised.

Description
The technology of the close subsurface drainage construction with using the force-feed of the volume-filter material by the narrow-trench drainage machine bin is described in the article. The results of the field study of the drains laid by traditional and proposed technology efficiency are shown
-
Description
The testing of jet pumps, installed on the recirculation line of circulation axial pumps are dealt with in this article. A number of experiments with nozzles of different diameter and installation sites have been conducted to increase the suction head of circulation pumps. The main conclusions have been done after testing
