Hydroelectric immune tests were applied to steel examples that were cover by concrete and tried when submersion in Salt lake water for different periods at temperature and at 50C. Results taken from Nyquist and forecast plots and as were broke down by recommends that of programming framework provided with the instrument. Results were gave on the grounds that the upsides of capacitance and opposition (Cdl and Rct). Results show that corruption happened when submersion inside the actually look at reply, and were extra serious at higher temperature. Examples were analyzed underneath examining magnifying lens, and micrographs showed clear crack and debasement in concrete coatings.

The article discusses the development of methods for preventing mechanical clogging of layers during underground leaching of uranium and the form of clogging.

The article notes that a suspended planner has been developed, equipped with a device that creates a soft layer of soil on the surface of the field. The leveler is designed with a central section and a side section that are pivotally connected to each other. The side sections are transferred from the working position to the transport position and from the transport position to the working position with the help of hydraulic cylinders. All sections consist of front and rear transverse and longitudinal braces connecting them to each other. The front cross brushes of the sections are equipped with leveling working bodies, and the rear cross brushes are equipped with compacting working bodies. Devices are installed on the rear crossbars of the sections, creating a layer of loose soil on the field surface. They consist of two rows of transverse beams equipped with teeth and are pivotally attached to the rear braces of the sections. To ensure the same depth of processing of the tool, its angular vibrations in the longitudinal vertical plane were studied. The results obtained show that for given operating conditions, the processing depth of the device is uniform at the level of requirements based on the correct selection of the thickness of its pressure spring.
