Current research purposes to find economical basis for choice among the
most widespread illuminating equipment. The analysis includes
comparison of its power and price, price of electric power, and also
durability of different illuminating equipment.
In the article energy saving in individual heating due to the low
temperature of heating agent is considered.
The optimal temperature drop for saving of heating agent is found.
Dependances between expenses on heating systems construction,
temperature drop and heating agent temperature are analysed.

The article includes algorithm for acoustic calculation of modern
ventilation and air conditioning system. The calculation for three
types of premises and the example of calculation for local radio and TV
studio are given.
It is the fifth part from a series of articles about influence of
climate systems on human organism
using the method of crystallization in gels.
Mathematical modelling and experimental data for crystalls growth in
gels are given. It is shown
that similar processes take place in human organism when polluted air
come into it.

Ways of influence of underground microflora and humic substances on
underground building structures
are analysed. Experimental data for soil samples are given. Soil
samples were taken from metro tunnel in the time of its technic
The classification for biological aggression of soils is proposed. On
basis of this classification the
research was conducted in the place of future inclined tunnels for
projectible branch of underground railway.

The classification of principal mistakes when designing and
constructing the industrial floors is made on basis of operational
experience and its scientific analysis. Mistakes in different phases of
project are considered: investigation of present foundation,
developpment of requirements specification, designing, construction and

In the article the waterproofing technology is described. It is the
alternative and in the same time the heir of traditional method "clay
lock". New materials on basis of hydrolyzed aluminosilicates of
have the same principle of work, but avoid a lot of disadvantages of
traditional method. Results of material tests for principal
physicomechanical properties are given in the article.

In the article the technology of waste use for developpment of armed
man-caused soil is considered. This material can be used in landscaping
and planning work, for creation of structural layers of road
foundations and as binding agent for stabilization of soft ground.
