Freshwater water resources are not inexhaustible [1]. In recent decades, more and more facts point to this statement from the European Charter for Water. Uncontrolled drinking water interventions, losses in water supply and climate change indicate the problem of sufficient quantities of drinking water [2]. Looking at this problem, it is hard to bel...

The article studies the effect of solar radiation at different seasons on the mode of deformation (MD) of a span structure with an orthotropic plate. The temperature fields of the elements of the structure were measured during daylight hours at different times of year at various air temperatures and sun positions. Cases were identified in which it ...
