Viscoplastic properties of chromium-nickel steel with the ever growing and a constant load. Part 1
Results of experimental studying of short-term creep of hromonikelevy steel are given at normal (room) temperature. Tests of thin-walled tubular samples were carried out in the conditions of a constant and in steps increasing loadings. When processing results it was used the main hypothesis of an uprogovyazkoplastichesky body according to which complete not elastic deformation is represented the sum elastic, plastic and vyazkoplastichesky a component. It is established that charts «vyazkoplastichesky deformation– intensity of nonequilibrium tension» depend on a type of a tension. Vyazkoplastichesky deformation at high level of complete not elastic deformation is comparable to instant plastic deformation therefore it should be taken into consideration at some types of processing of metals by pressure.

About destruction of concrete dams on the soft basis
The article covers physical and mathematical model of the process of breaching of concrete dams on a soft base by bottom currents. The model is represented by a system of ordinary differential equations of the first order. The numerical algorithm is developed for solving the system, presuming the special conditions are imposed for integration of the equations in case of washout of sections of a multisection dam. The solution is obtained through explicit single-step integration scheme (Runge-Kutta-Fehlberg method) — both for single-section and multisection dams. The integration scheme is modified taking into consideration the special conditions formulated to be imposed on the sections. The graphs are constructed for the following functions: breach development and water storage level. The worked out approach allows to solve a number of problems oriented on erosion of dams on a soft base, consisting of many sections. The model is burning for damage estimates from the consequence of the dam-break wave, the estimates necessary for undertaking protection measures from emergency situations connected with catastrophic breakdowns of dams, and for minimizing the damage from breakdowns as well.

Principles and methods of improving protectability of control systems of critical facilities
The paper addresses principles and methods of protection design of control systems (CS) of critical facilities (CF) from damage factors of technogenic accidents and catastrophes. It is necessary to note that when assessing the protectability level of СF control systems one should take into consideration mechanical, thermal, electromagnetic, radiation and other effects. The basic kinds of vulnerabilities of CS are identifi ed. These include: objective, subjective and stochastic vulnerabilities. The paper presents an algorithm for protection design of a control system based on threat and vulnerability analysis, the main directions of vulnerability reduction for control systems are discussed. The protection schemes based on classical concept of in-depth defense for protecting CF control systems are introduced.

Laboratory research of waste decomposing in bioreactors for assessment of biogas potential and choice of measures for aftercare phase
There is substantiated in the article suitability of carrying out experiments on research of waste decomposition processes on model samples in bioreactors. To assess in situ condition and impact of municipal solid waste (MSW) landfills on environment it is necessary carrying out long-term laborious full-scale observations. Thus more attention should be paid to calculation methods of assessment using laboratory research results obtained in bioreactors. There are simulated with high reliability conditions of going on biochemical processes in landfill body. It gives an opportunity to choose needed mathematical models and to correct their parameters. Using the specified methods allows in a short time to obtain necessary information on waste decomposition processes in landfills, to assess biogas potential, degree of their mineralization at various stages of biochemical processes and to choose measures for aftercare phase.

Heatmasstransfer in sea water desalination systems with solar heater
There are analyzed the heatmasstransfer processes, performing in equipment of one of possible sea water desalination systems, acting with solar heating source usage. The circulation in system air is humidized by the sea water, then it is heated in solar heater and enters in a dehumidizator — condenser, which is cooled by sea water in flow. A desalinated condensate is directed to fresh water consumer. There is considered in detail a process of condensation of system from moistened steam — air mixture in a heat exchanger — dehumidizator of plate type.

Formation of active forms of oxygen in water solutions of salts of uranium at influence of electromagnetic fields
Complexity of express control of compounds of uranium in natural waters is shown. Influence of electromagnetic fields on generation of active forms of oxygen in water solutions of compounds of uranium is investigated. Observable character of nonlinear generation peroxide compounds contacts macroscopical quantum behavior of system that will allow to consider at the further researches on working out of express control of uranium in natural waters.

Sufficient conditions for existence of free convection flow in vertical narrow channels
It is proved that the existence of free convection flow (FCF) in a vertical slit with asymmetric heating is sufficient to satisfy the condition:0 < n< nex, where nex — the polytropic index in the FCF, nex - polytropic index corresponding to the equilibrium state of the gas column. In particular, if the equilibrium state corresponds to the condition of no supply of heat, then: 0 < n< k, k— ratio of specific heats. For the existence of the gap in the maximum mass flow rate it is necessary that: n=gL/RT0, where L— the height of the slit, T0 - temperature at ground level. Polytropic index n is related to the intensity of heat transfer from hot wall to the flow: with increasing intensity of heat transfer n →+0.

Engineering-diagnostic inspection of build objects of north-western TEC
The features and results technical inspection structures of waste water treatment building of North-West TEC in St.-Petersburg are described. Non-load-bearing brick walls and reinforce–concrete columns lean on concrete foundation slab. The reasons of crack origin and development in brickwork are exposed. The main reason is uneven deformations of foundation slab at the different filling of reservoirs. The results of instrumental reserches and model experiment are confirmed by calculations. Offered and realised measures of constructions strengthening, after that cracks development was halted.
