In order to find the optimal solution for the drainage of rainwater from roads in urban areas, as well as for the evaluation and ranking of conceptual solutions, appropriate mathematical models and software packages were used in this research. For relevant rain episodes, i.e. rainfall of appropriate duration and intensity, runoff coefficients and f...

Plasma coating technology was applied to machine parts. During application, the jet formed hits the surface of the material and particles are deposited on the surface. In this way, layers of high thickness can be applied and thus revitalize worn machine parts. The paper examines the abrasion resistance of Al2O3 and Al2O3 phosphate layers applied to...

Magmatic rocks of post-Late Eocene magmatic formation are widespread in the Sava segment of SavaVardar suture zone and adjoin areas. The rocks formed as a response to transpressional-transtensional tectonic activity preceded by the Cretaceous-Eocene compression of the Internal Dinarides and Tisia Unit as fragments of Eurasian continental lithospher...

Deicing reagents have an impact on the environment. The composition of the deicing reagents used in Moscow has undergone certain changes. However, the main components of deicing reagents were chlorides, including calcium chloride and (or) sodium chloride. We also conducted research on the effects of sodium chloride and calcium chloride on some urba...

The tentative permissible concentrations and the maximum permissible concentration of heavy metals do not always give a complete adequate assessment of the effect on plants. Plant growth inhibition can be at concentrations below the maximum permissible concentrations and tentative permissible concentrations. We studied the effect of copper, zinc, c...
