Сontinued on the development of a new approach to solving the problem of automatic control system for the maintenance of a level of subsoil waters (GWL), which is organized on the base of industrial controller Octagon  with the use of invariant Nonstationary three-dimensional mathematical model of polder systems (IP) as a tool for monitoring parameters. However, the mathematical model of the PS does not count  soil temperature, which may affect the moisture transport processes in the drained filter coefficients through the array, moisture permeability are put, and so on, so the main objective of this work is to develop an effective algorithm for calculating the temperature regime of the soil in the drained area and some clarification of the controller software. The temperature of the soil is described by the equation of the effective thermal conductivity.

The change of embrittlement of U10A steel and microhardness of 65G steel due to the cathodic polarization in 0.1N H2SO4 solution in the presence of saccharin has been investigated at current densities within the range from 5 to 60 мА/см2 . It is established that at the densities of current 5 and 10 мА/см2 and concentration up to 0,1 g / l saccharin acts as an inhibitor of steel hydrogen charge. It is shown that saccharin at concentrations more than 0.1 g / L H2SO4 in the solution acts as a stimulant steel hydrogen charge U10A for all investigated current densities. Нydrogen charge of the 65G steel due to cathodic polarization in 0.1N H2SO4 in the presence of saccharin will causes as a rule to essential reduction of microhardness.

The differential thermal analysis of sulfur of different modifications is conducted from room temperature up to 400 0С at warming and cooling: rhombic sulfur, rhombohedral sulfur, alloys of rhombic and rhombohedral sulfur, plastic sulfurand several sorts of polymeric sulfur. The method of obtaining nonspecified in the literature of modification of polymeric crystalline sulfur of black colour essentially distinguished from filamentary sulfur, is offered. The dynamics of changing a state of rhombic, rhombohedral, plastic, filamentary and black chain modifications of sulfur in four-ten series cycles “heat - cooling” is researched. The outcomes of research testify to saving key features of frame of melts of the studied modifications of sulfur, that indicates a block structure of their melts. The research by a method DТА of melts of mixtures of rhombic and rhombohedral sulfur at heating and cooling has shown, that in limits of identical conditions the transition from one form of sulfur to another happens practically monotonically, that testifies to their mutual solubility in metastable melted and crystalline states and about saving individuality of appropriate nanoparticles.

Application of the EoS method allows to describe all kinds of equations of state leading to four types of singularities at nonzero value of the scale factor. In this paper, we consider the effect of crossing the phantom divide and raised the question of the form of the corresponding equation of state. It is shown that the point of crossing the phantom divide linked to a branch point of the equation of state.

Action of moderate Pb2+ concentrations on physiology-biochemical values of the 1 st true leaves of wheat (Triticumaestivum L.) seedlings using markers of general use was explored. Stress changings from 0,03 mg/l Pb2+ concentration and the switching of stress phases were demonstrated. Phenomena of predominance of anti-stress processes over toxic pollutant action, of stress answer without changes of photosynthetic pigments levels and of activation of some processes at minimal Pb2+ concentrations were found. Observed processes are discussing concerning with advisability of approaches for further researches of the lead-induced biological stress.
