The discovery of radioactivity at the turn of the 19th and 20th centuries stimulated the rapid development of nuclear sciences. At the interface between nuclear physics and chemistry, disciplines such as radiochemistry, radiation chemistry and nuclear chemistry were formed.

The aim of the Nuclear Chemistry course which is taught at the PF UPJŠ is to provide basic knowledge, with an emphasis on the general value of the subject. It is important to make available the basics of various methods, techniques and their specifics in the application of nuclear phenomena in chemistry and related fields. Emphasis is also placed on the use of correct terminology, knowledge of the context of relationships and basic principles, supplemented by illustrative concrete cases.

The choice of material is rather difficult, but we count on additional monographs and textbooks to fill in the gaps of these teaching texts.

An important part of theoretical computer science is the problem of Turing machines. This computational model has two basic properties: like any other computational program, the software of a Turing machine is composed of instructions, but in its case they are all of a single type. Every other (so far known) computer program can be transformed into a Turing machine program without loss of information. While the second feature reduces the question of what a calculator cannot do to the question of what a Turing machine cannot do, the first feature allows a much simpler investigation of such a question. Using this computational model, we can thus find concrete problems that no automaton can ever deal with (perhaps the most famous is the problem of the Turing machine stopping). Their existence demonstrates the fundamental limitations of (not only ideal) computational means, and thus encourages both criticality and humility in our thinking.

Selected tasks and problems from biochemistry – metabolism follow biochemistry lectures on metabolism and individual metabolic pathways for students of the second and third year of the bachelor’s degree in the fields of chemistry, biology and their combinations with other fields. Scripts provide an opportunity to better understand the lectured subject matter of metabolism through the solution of tasks and problems as serve as a basis for one-hour exercises. The scripts are divided thematically into eleven chapters, and each chapter contains 10 tasks and 7 problems. At the beginning of the chapters there is a short description and explanation of the given metabolic pathway. However, when solving the tasks, the student must focus mainly on the curriculum that was presented on the given topic in the lecture. Subsequently, at the end of chapter, answers to problems are also presented. These scripts are intentionally accessible only in electronic form. The reason is the effort to continuously update and modernize individual tasks.

The laboratory rat (Rattus norvegicus) is one of the most commonly used experimental animals. It serves as a model organism for analyzing numerous biological processes and pathological mechanisms, such as cardiovascular diseases, metabolic disorders (e.g., lipid metabolism, diabetes mellitus), neurological and neuropsychiatric conditions (e.g., stroke, epilepsy, or Alzheimer's disease), neurobehavioral research, autoimmune diseases (e.g., arthritis), cancer, and renal diseases. It offers many unique advantages for modeling human diseases, testing drugs and natural substances, and studying responses to environmental factors. The size of the laboratory rat, compared to the mouse, creates ideal conditions for physiological manipulations. Additionally, rats are used in clinical toxicology to test chemical substances (Hedrich, 2000).

We have prepared a publication that focuses on the personalities of professors. These personalities represent entire scientific teams, participated in the creation of new study programs, and had a significant impact on the formation of the faculty. Factually, we tried to capture the basic data in a uniform structure. We are building on a similar publication from ten years ago, which greatly helped us, especially with professors who worked at the faculty many years ago and whose memories are gradually fading. The ambition of the publication is to contribute to the preservation of basic information that is closely related to the history of the faculty.
