Description
We investigated the basic soil types (brown, brown wood) of foothill zone of Dagestan. We revealed that the distribution of nickel, chromium and lead in the soils depends on several factors: soil-forming rock, physical clay, humus and pH. We defined the background content of heavy metals in the studied soils of the region

RECOMMENDATIONS FOR THE ESTABLISHMENT OF PROCESS CONTROL SYSTEMS FOR HEATING AIR DRYING OF SEEDS
DescriptionThe article presents the recommendations for a process control system of heated air for drying seeds. The problem of selecting a control device is solved. The calculations of transfer functions of the closed ACS are made. The optimal controller gains are found.

MONITORING INTENSE THE DEFORMED CONDITION HYDRAULIC ENGINEERING CONSTRUCTIONS MELIORATIVE SYSTEMS
DescriptionResults of operational monitoring are given is long maintained GTS of meliorative systems with nondestructive control methods. Possibility of use of devices of nondestructive control is especially noted at inspection of hydraulic engineering constructions, on an example of water carrying out channels that allows operatively, without additional damages, to receive an objective assessment of their technical condition. When using this approach, there is a possibility justification of parameters of defects and damages, which is impossible to establish at visual survey. The program complex for modeling of a technical condition of holding channels for calculation of predicted term of their service is also presented
