Graphenes in the form of flexible thin films treated with different types of plasma were investigated by Mott-Schottky analysis. The possibility of variation of electrical conductivity in graphene prepared by plasma treatment was shown. Obtained materials are promising for electric energy storage devices.

In the article the authors considered electric loads for the period of August – October 2017. The values of mathematical expectation, dispersion, standard deviation, coefficient of variation of electrical loads, as well as the maximum and minimum of load values per day, month, quarter are determined.

An example of the course of extracurricular activities on the basics of programming the Arduino microcontroller. Describes the features of using project method in teaching electrical engineering for students.

The article analyzes ecological reforms of Uzbekistan’s industrial towns, especially towns of Tashkent region, during the years of Independence. The analysis shows the improvement of ecological balance, as a result of governmental arrangements undertaken for solving the ecological problems in the town. The article demonstrates the abatement of industrial pollution as a result of re-organizing industrial factories by investments. The statistical data shows the reduction of air pollution by deleterious waste in the town, which was caused by the effect of industrial plants reorganization that phase down during the first years of Independence, as a joint venture and technical and technological re-equipment of them. The ecological state of each industrial town is analyzed separately in the article. The author uses governmental decrees, periodicals, documents of town hall, archive data, as well newspapers and magazines that show eco-environment of the republic.

This article considers the problem of determining the quality of electrical energy. The author examines the main indicators of electric power quality. Finally the conclusion about the paramount importance of power quality in the development of measures to reduce the process of energy consumption was made.

One general definition of corrosion is the degradation of a material through environmental interaction. The authors consider the corrosion of pipelines. Material EC-sequence may be useful to those skilled in the technical field.
