This article is devoted to a comprehensive study of drinking water before and after its purification. Water samples taken at 5 water supply and 5 water distribution stations of the city were used in the study. The author comes to the conclusion that the use of the monitoring system allows you to respond quickly to any changes in the quality of the drinking water, and quickly make decisions that affect its purification.

This article deals with the task of design education in the training of specialists who are ready to implement creative ideas in the design of environmental objects. It gives a detailed analysis discipline of academic painting. It is reported about the study of pictorial techniques, rules and patterns of academic painting, which are necessary when performing creative tasks. The stages of color design of the project are considered in detail, with the implementation of which various graphic techniques of watercolor painting are used.

Relationships of cause and effect which are the cornerstone of the phenomenon of observability of area of hydrophysical indignations from an underwater moving object, including its exit to a sea surface when lighting the area in the thickness of water by a laser beam and radiation of the sea surface over an object with a radar station signal are described in the article. In the stationary marine environment the laser beam creates a backscattering signal of a fixed level. In the area of hydrodynamic indignations from an underwater moving object the signal of a backscattering of variable brightness to the relevant structure and level of indignations is seen. The similar phenomenon of a backscattering of the electromagnetic radiation of radar station that creates glare effects on the screen of radar station in a zone of an exit of hydrodynamic indignations is observed on a water surface. It is shown that these phenomenons have similar nature caused by the change of dimensional orientation of dipoles of molecules and liquid crystals clusters of water in the field of the hydrodynamic indignations accompanying the moving of an underwater object. Establishing of this characteristic, in case of its confirmation by test data, meets the requirements of qualification of opening.

Water has unique properties. The chemical composition of water is very important for humans, since a person 60-70% consists of water. My research was devoted to the study of the content in the water of the rivers of St. Petersburg of such chemical elements as iron and chlorine. The results of the research showed that tap water meets the sanitary requirements of drinking water quality, while in the river waters there was an increased content of the investigated elements.

This article examines the methodological aspects of the development of color vision at the initial stage of painting education. Various ways of solving this problem are proposed, namely, the implementation of the process of developing a color vision from various points of view, theoretical, practical and methodical. The article describes a set of exercises using the example of watercolor technique, with the help of which color problems of different levels of complexity are solved and stage by stage lead to the expected result.

The article presents the design of absorption-diffusion refrigeration unit distinguishes than that, with the aim of increasing efficiency, a reflux condenser and absorber is fitted with cooling jackets, and the evaporator has a collection of melt water, is connected in parallel to the shirts of the reflux condenser and the absorber. The article also presents the design of the test stand generator the above absorption-diffusion refrigeration unit, characterized in that, with the purpose of testing in a wide range of values of the cooling capacity of the test generators, the stand further comprises electrochlorinator with a regulating valve at the entrance, acting as a refrigerator evaporator, heat exchangers with the coils connected among themselves by means of piping and employees fracking, condenser, absorber with reservoir, liquid and gas heat exchangers of the refrigerator, and the water distribution manifold with regulating valves connected to mirzoalimov spaces of the respective h

The article deals with the organization of the market of container transportation by rail and water transport. The authors came to the conclusion that due to the excessive supply of transportation capacities, which will remain a fundamental problem of the world container market at least until 2019, negative dynamics of sea freight rates will be monitored.

This article discusses how to use solar energy to heat a building and develop a new device for generating heat from the sun. The author presents two types of solar energy usage.

The article represents an option of shared use of the solar energy equipment and traditional thermal equipment, which allows system to work from single heating room, and from solar energy in combined form. The graphs of the results of solar power measurements on different surfaces are represented. The formula obtained on the basis of measurements is given, which makes it possible to calculate the solar energy received per day.
