At the present time a new design document
“Ventilation and heating of shipyard shops”
commissioned by the Department of
shipbuilding industry, Ministry of Industry and Trade of Russian
being worked out. The second edition of the document was endorsed by
leading shipbuilders, design and research organizations. Government
confirmation of the document is planned on December 2013.

The features of microclimate creation in living
quarters where outside air inflow comes through ventilation valves are
with respect to different types of heat appliances (convection heaters
radiators). The numerical simulation was used. Hydrodynamic equations
solving taken with
initial and boundary conditions allowed us to obtain information about
temperature distribution and air speed in the studied volume.

The possibility of "membrane
activation" of the coagulation process was tested with the polystyrene
latex model system. In addition, there was shown a lower rate of the
electrolytic coagulation with the model system based on phosphate
sodium chloride, an organic dye, gasoline, sodium sulfide than with a
system adjusted to positive values of redox-potential using hydrogen
The basic laws of Prandtl semi-empirical turbulence theory were
in the article. It was shown, that the Prandtl – Nikuradse
distribution of velocities are not strictly universal. The change of
the first and second turbulence constants was analyzed on
the basis of experimental data of I. Nikuradse. The logarithmic
profiles for smooth and rough pipes have been transformed.
A version of the
engineering kinematic theory of contact earth pressure in the
the water-transport and offshore structures was suggested in the
article. A dimensionless static “compression
– tension” diagram of the soil, presented by
curvilinear function, was used in
the method. In this case, the displacement of the limit point of the
determined with the account of the plastic deformation modulus in the

This paper is dedicated to the development and
approbation of methodology and GIS-based tools for calculating
potential of rivers, located in Russian Federation. The list of initial
and information sources used in research were described. The approaches
and GIS-tools described in present
paper allow executing an assessment of hydropower potential of the
rivers in a
short time on large areas.
