Elements selected as ready-made modules were scanned by means of an Atos Professional 3D scanner (Fig. 1).
An important role in the description of robot movement under water is also played by the force present in equations (7) and (8), i.e. the buoyancy force defined by the expression: , (10) where: g - gravitational acceleration, ρ - medium density, U - robot volume.
It was necessary to select water as a liquid flowing around the robot and assume the liquid pressure as well as velocity.
Determining parameters for the robot body Simulations of liquid flow around the different robot configurations were performed at various pressures both for open water reservoir and various diameter pipe conditions.
In-depth knowledge of these parameters was necessary to perform simulation of robot behaviour in water and to design its control system.

The most valuable part of the object is a fresco of the fresco-secco type with shades of natural colours dissolved in lime milk or water and applied to a half-dry, respectively refreshed plaster.
Professional circles agree that year 1134 stated in the inscription is correct.
Degradation of the inner fresco decoration Stone, bricks, plaster, fresco and other materials that contain water-soluble salts in their pores are very sensitive to changes of the indoor climate.
Changes in the relative air humidity may cause the dissolution of these salts or conversely the crystallisation due to the water evaporation.
The pressure of water vapour at the wall surface pw [Pa] may be considered the same as the pressure of water vapour in the air pi [Pa].

The high contamination of water in such soils decrease the effective stress and reduce bearing capacity.
The problems of clayey soil appear when it is wetted or saturated with water [2,3].
The loading frame was locally manufactured with the aid of professional's technician consists of (1m) solid circular shaft made from stainless steel.
This new technique may increase the water absorption in addition to compact sides surrounding the stone column in a radial direction because the pure bentonite particle increases about 15 times, when wetted with water.
It is believed that using stone column may reduce the water content of soil by absorbing the additional water in radial direction through the porous inside the stone column with the aide of capillary action from the porous inside stones and then would extrude out water from the upper portion.

Professional microbiologists leave petroleum industry leading to less in-house
scrutiny of procedures and practices, and less research.
Even free water must be 'available' water which microbes can adsorb.
Water in fuel may come from sea water carry over from cargoes, rain water, ground water or from condensation.
This water will usually start as free bottom water or as condensate on surfaces but it may later become a water-in-fuel dispersion.
Corrosion in Water Tanks and Cooling Water Systems.

Several current problems about research methods of rainfall landslide were put forward:1)complex conditions apply problem;2)the Response rule of landslide surface moisture;3)the variation of surface the water content in different parts;4) The development and change law of landslide thrust force under the action of rainfall need further inquiry;5) lack of factor analysis of variation characteristics and influence of rainfall conditions the development law of landslide displacement and the displacement of landslide in different parts;6) lack of analysis and research interactions between multiple physical effects.
Domestic and international statistics show that the landslide process water is the most active and positive factor, most landslides induced by rainfall.
Godtet et al.(2005)[7] has study of the early influence of rainfall on landslide and puts forward the concept of pre-Moisture Index(Unit soil column retention capacity of the water height, to some extent, it implies that the soil, topography, landforms, hydrological condition), And as a basis for judging whether the landslide instability in a rainfall conditions, gives the curve of rainfall intensity induced landslides in Seattle area of the United States .
