Abstract

The Nencki Institute of Experimental Biology of the Polish Academy of Sciences in Warsaw, one of the largest nonacademic biological research centres in Poland, celebrates its 100th anniversary. The Institute was established in 1918 by the Scientific Society of Warsaw. In 1945, after World War II, it was re-established in Łódź and in 1952 incorporated into the newly founded Polish Academy of Sciences. During the period of 1953–1955 a newly erected building at 3 Pasteur Street in Warsaw became the home of the Nencki Institute. Today, the Nencki Institute strives for excellence in basic research in the broad sense of biological sciences. Neurosciences and biological and molecular basic of civilization diseases represent two main research areas of the Institute in the context of the society needs to improve the quality of life. One of the strategic activities of the Institute is investments in bio- imaging.This has recently resulted in inclusion of the Institute in the EUROBIOIMAGING project of the European Strategy Forum on Research Infrastructures (ESFRI). An excellent example of a synergy of basic and innovative studies is the Neurobiology Centre established at the Nencki Institute in 2010–2013 as part of a strategic project entitled the CePT. Additionally, the Nencki Institute trains nearly 200 PhD students under various programmes, including the H2020.

Abstract

Professor Lech Wojtczak spent his entire scientific life at the Nencki Institute of Experimental Biology PAS, where he worked since 1947. He is the author or co-author of two hundred scientific papers, promoted 15 doctors of science, was the Full Member of PAS and has been awarded with several prizes and honors. Among his students are three successive directors of the Nencki Institute, the authors of the present article. Scientific interests of Professor Lech Wojtczak were always dealing with bioenergectics, a discipline that he led in Poland and Eastern-Central Europe. In particular, his studies focused on the role of fatty acids and their derivatives on bioenergetics, on the regulatory role of surface potential of biomembranes on enzymatic and transport activities, on the regulatory role of calcium and magnesium in mitochondria, on the role of free oxigen radicals in bioenergetics, etc. Apart from being a great scientist, Lech Wojtczak was also a fantastic teacher, and an excellent scientific supervisor. Being well recognized in the world, he was placing members of his research group in foreignlaboratories, as well as was sending tchem to courses and conferences. This was opening their minds to the world, and to other cultures, and allowed Lech Wojtczak to form from his collaborators the next generation of good scientists and future leaders. The list of the most important pupils of Professor Wojtczak is given in the article. Lech was also excellent in social contacts, and in creating a friendly atmosphere. Together with his wife Anna, they kept an open home, often inviting collaborators to parties that usually led to long scientific discussions. With the sudden death of Pofessor Lech Wojtczak Polish science suffered a great loss. This eminent researcher, the father of Polish bioenergetics, but also a warm and modest person, will be dearly missed.

Abstract

In this paper we described three Art & Science projects organized by the Nencki Institute of Experimental Biology (Polish Academy of Sciences), Marcel Nencki Foundation for the Support of Biological Sciences and the Art Department of the University of Rzeszów. First project, celebrating the 100th anniversary of the Nencki Institute, was entitled “Biological imaging: inspiration by invisible world” and took place in Mikołajki in 2017. Next two projects were relating to “Art of Biodiversity” (Rzeszów, 2018) and “Power of Biological Structures” (Przeworsk, 2019). The aim of the projects was to introduce ideas of modern experimental biology to artist. All symposia/workshops were followed by few exhibitions at the Nencki Institute of Experimental Biology, Art Department of the University of Rzeszów, etc. Some of paintings originated during these projects established Nencki Art Collection, collection of modern art at Nencki Institute of Experimental Biology.

Abstract

Paper presents methodology of generation of the uniform, compressive or tensile stresses in ring-shaped amorphous alloys core. In this study we use the set of special nonmagnetic, cylindrical backings. These backings enabled the core to be wound as well as create the possibility of generation of uniform compressive and tensile stresses. Using presented methodology the magnetoelastic characteristics were experimentally determined for Fe40Ni38Mo4B18 Metglas 2826 MB amorphous alloy. Knowledge about these properties is important for users of inductive components with amorphous alloys cores due to the fact, that changes of flux density due to magnetoelastic effect exceed 40%.
