Dear Colleagues, dear Readers! We have prepared for you the second issue of the fourth volume of our scientific journal Acta Technologica Dubnicae, which is polythematic again. As a novelty, we are happy to announce that we have entered into cooperation with De Gruyter Open and our journal will use the open access publishing model from this issue onwards. De Gruyter Open (www.degruyter.com) is one of the world’s leading academic publishing houses headquarted in Berlin. Its name has been a synonym for first-class publications presenting significant scientific findings and discoveries for more than 260 years. De Gruyter Open publishes Open Access scholarly journals across all major disciplines. These journals are freely available at www.degruyteropen.com. Most of them are owned by universities, research institutions, scientific societies and other organisations. Acta Technologica Dubnicae has become one of them and you can find our studies and professional articles there. The printed version of the journal remains unchanged. What is new in this issue? The first section of the journal is opened by Slávk
