If the strategic goal of education is declared as social economic progress, the humanity should not have any problems with solving its current and future problems significant for the living arrangement of the world population. It should be noted that the process of globalization of a biospheric environmental disaster is not an urgent problem for Russia. In particular, Russia has spent its territorial biocapacity by 50% and, as a consequence, it acts as a global ecodonor. However, even in the 80s of the last centur...

After the end of use, they become e-waste and are recycled or put on the landfills. Recycling rate of e-waste in Slovakia was in 2017 according to Eurostat only 36.7 %. Recent studies show that yields from e-waste (mainly computers, mobile phones) are much higher than in metal ores and thus can be considered as valuable secondary sources of precious and base metals. In presented paper five different parts of computer e-waste were investigated for possible gold recovery, namely CPUs, CPU sockets, BGA chips, pins fr...

A thermocline is a layer of water in which a vertical temperature gradient is observed. On freshwater lakes, it is caused by seasonal warming of the surface layer. In the absence of wind mixing, the upper water layer is heated relatively uniformly, the temperature in the lower layer does not change. The temperature transition between the surface and bottom layers creates a thermocline. Since a change in water temperature leads to a change in its electrical conductivity and dielectric constant, a thermocline can be...
