The 51st volume of the journal contains articles representing the latest research results in electrospinning and additive manufacturing technologies with the use and production of biodegradable polymer materials for wide applications, mining wastewater treatment and processing sludge from water treatment. This publication presents also the numerical investigation of methods for the settlement reduction of a light-weight highway embankment on soft soils, the study of the dynamic behaviour of a distributed static synchronous compensator installed in a distribution network, the design of a pantograph for railway overhead power lines, and results of experimental investigation performances of diesel generator fueled by biodiesel. This volume will be helpful to many engineers in the chemical industry, geotechnics, machinery and power engineering.
