In the article, the embodying of operation of integrating of systems, being generalization of operation of integrating of sets within the limits of system generalization of the theory of sets is considered. This operation is similar to bulean integrating operation of the classical theory of sets. However, unlike the classical theory of sets, the concrete algorithm of integrating of systems in its system generalization is offered and the quantitative standard system effect (synergetic, emergetic) arising with the application of integrating of systems is proved. For this standard, the unique name is offered: «The generalized coefficient of emerge by R.Hartley» because of likeness of its mathematical form to the local coefficient of emerge by Hartley, reflecting a degree of difference of system from the set of its base elements. The reference to the author's program realizing offered algorithm and providing numerical modeling of integrating of systems at various restrictions on complexity of systems and at various power of generating set is given, some effects of numerical modeling are given

PROTECTION OF THE KUBAN RIVER AGAINST FLOODS BY MEANS OF WORKED-BU-WATER FLEXIBLE DAMS
Description
The article deals with constructions of fast-erected dams from high-strength polymeric materials as well as with their production engineering and erection at a point of the dam failures and washouts of riverbeds. And the flowchart of work production on elimination of consequences by dam failures, their geometrical parameters and estimated cost also. Parameters and criteria of flexible dam’s stability for shift and over-turning are presented

Description
Hereby are represented: method and results of experimental research for substantiation of rational operating mode for honey centrifuge electric drive. Empiric model of influence of honey temperature (from 20 to 30 оС) and honey humidity (from 17 to 21%) on initial rotating speed of centrifuge was worked out. Rational operating mode of honey centrifuge electric drive consists of 3 stages of honey output. Rotating speed of drum with allowance to the honey temperature and humidity for each stage was substantiated. There is an example of model using. Recommendations for application of research results are given

Description
Hereby an urgency of electric drive with rational operating mode for honey output centrifuge is substantiated. There was ascertained, that exposure of regularity of honey movement out of the cell-frames within centrifuge during the honey output will let to work out rational electric drive for centrifuge and to reduce a work content of the technological process. Principal electro scheme for centrifuge electric drive controlling is given here. Feasibility study for honey centrifuge rational electric drive application for serving an apiary, consisting of 100 colonies of bees is performed here. Recommendations for application of research results are hereby given

CAPACITY OPTIMIZATION ON THE IRRIGATION TECHNICS
Description
Mathematical modeling of process of an operational parameters choice of watering techniques, which can be used as the theoretical basis, allowing making multiple numerical experiments for the purpose of results reception for a concrete irrigated site, is considered. Article is recommended for researching and other organizations at designing new and reconstruction of existing sites, and for the operational organizations at decision-making of a choice of technology and watering techniques
