However, they are not comfortable because they are not water proof and difficult to make movement.
Geomagic Studio is a platform that enables engineering and design professionals to create accurate digital model from any physical part.

Moreover, the cost of daily maintenance required is large and professionals are also required, which is not a small operation cost for travel operators.
They should choose environmental, green or ecological hotels with less energy consumption and form good habits of saving water and electricity.

In the first stage there is a 6-hour solid solution treatment at 530 ºC temperature and then the castings are intensively cooled down in water of 60-80 ºC temperature.
According to the professional literature [2] if the magnesium content of the alloy is solved it increases the value of lattice parameter.
Figure 8 illustrates G-P zones in different magnification rates. [4] Reading the professional literature we found photos where G-P zones can be seen more sharply but in these photos it is more difficult to see them in the matrix and their composition cannot be identified either. [5, 6] Figure 8: Photos of the Guinier-Preston zones Summary Our task was to find other heat treatment parameters to reduce the treatment periods and power consumption (530 ºC temperature - 6 hours and 210 ºC temperature – 3 hours).

According to Table 1, it can be verified that three different types of concrete samples have been molded, the only difference between them was the quantity of water in concrete.
It has also been verified that the higher the amount of water in concrete is, the lower the electrical resistivity is too.
It is know that the higher the amount of water in concrete is, the higher its permeability also is [9].

Water volume of roof gutter is concerned with diameter and amounts of the downspout.
The distance for rain water draining shall be no more than 30 m, and the water drop in gutter should not exceed 200 mm. 4.

It denotes great interest not only in scientific sphere but also in sphere of results application in the new developing methods and their using in professional practice.
In traditional power stations is combination of steam turbine and alternator, where aggregates are transformed into heat and mechanic energy removed from heated water vapor.
