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.

Among students of single-discipline and interdisciplinary biology studies at faculties with a natural science focus, there often arises a problem in defining the scope of the curriculum when studying the subject of Human Anatomy. The presented study material aims to help students of non-medical scientific fields navigate the extensive anatomical terminology and to limit the amount of required anatomical terms to an optimum, so that alongside mastering Latin nomenclature, students still have sufficient capacity to memorize additional knowledge in the areas of systemic, comparative, developmental, and functional anatomy.

Emphasis on organizing individual anatomical terms into logical units simultaneously supports a hierarchical view of the architecture of the human body. Despite its seemingly self-serving nature, anatomical terminology thus becomes the framework upon which students build knowledge from more or less related scientific disciplines studying the human body and the processes occurring within it throughout their further studies. At the same time, alongside this ambition that goes beyond the scope of the anatomy discipline, the Anatomical Terms follow a long tradition of anatomical handbooks while respecting the valid Latin and Slovak anatomical nomenclature.

This script represents a practical supplement to university textbooks of Anatomy or Neuroanatomy and especially to anatomical atlases, but it certainly does not aim to replace them. Here you will find all the necessary terms gathered in one place, which you can always have at hand on your phone, e-reader, or laptop. The emphasis on organizing individual anatomical terms into logical units supports a hierarchical view of the architecture of the human body, and the inclusion of a brief introduction to each system is intended to encourage you to seek further, more detailed information about the structure and function of the given organ system.

The text ‘Uptake and transport of mineral substances in plants’ in Slovak language provides a general overview of the uptake and distribution of substances in an easy-to-understand form.

The individual chapters introduce students to the properties of the soil environment, which have a significant influence on the availability of substances, as well as the transport of substances across membranes and over medium and long distances. The text contains the latest findings from the English literature, supplemented by diagrams and graphs created by the author on the basis of his own research or by compiling several sources.

The text is intended primarily for students of a master's degree in biology or ecology and assumes at least a basic knowledge of plant physiology.

Solving crystal structures is the royal discipline of X-ray crystallography. Its primary task, with the exception of defects, is to describe the atomic structure of the motif that, by its repetition, fills the volume of the entire crystal or crystalline phase. This task is nowadays more or less routine for single-crystal X-ray diffraction, which can locate hundreds to thousands of non-hydrogen atoms in large unit cells. However, in real practice, we often have material available only in powder form instead of single crystals. Solving the atomic structure from its X-ray diffraction data is non-trivial, mainly because the three-dimensional diffraction space of a single crystal is reduced to one dimension by measuring a large number of randomly oriented microcrystals (crystallites). Therefore, the solution itself requires, in addition to proper measurement methodology, the selection of suitable tools, procedures, and strategies that, through optimization, will lead to the solution and refinement of the given crystalline phase. The current limit of this method is approximately 100 non-hydrogen atoms in the asymmetric part of the unit cell, which, however, is sufficient for most inorganic materials.

The goal of these educational texts is to provide students in the second and third levels of university studies with specific guidance on solving crystal structures from powder X-ray diffraction data. These scripts build upon my first monograph and require practical knowledge of its content. Similar to my previous monograph, I offer solved examples without a deep theoretical introduction, demonstrating procedures and strategies leading to the correct solution of crystalline phases using the freely available GSAS-II program. The examples are arranged from simpler to more complex, and the reader will find many useful pieces of information in the literature references as well as in the comments below the line. Part of these scripts are data intended for your individual practice of the described procedures.

This electronic material focuses on the subject of secondary metabolism and its products - secondary metabolites. The material gives an overview of the basic building blocks and construction mechanisms through which molecules can be synthesized in living organisms (plants). The processes of formation of the mentioned metabolites are explained using the basic mechanisms of organic reactions. Several of the secondary metabolites presented have a remarkable biological profile and are used as therapeutics or serve as lead compounds for the development of novel pharmacological agents. This electronic document is primarily intended for students of the Master's degree programme in Organic Chemistry as supporting material for the profile subject Chemistry of Natural Products.

Flow cytometry is a diagnostic and research technique that enables rapid analysis of cells, nuclei and organelles of plants and other organisms. In plant biology, it is most often used for DNA content analysis in a wide range of applications. It is the method of first choice and its importance is even increasing compared to competing technologies. It is unrivaled in speed, accuracy, repeatability and low cost. Flow cytometry has become a standard tool in laboratories focused on biological-ecological plant research.

This textbook provides information on the historical development of flow cytometry and its establishment in the analysis of the plant genome. It describes the procedure of sample analysis to determine the nuclear DNA content and presents the basic applications, such as determination of genome size, ploidy level and reproduction modes of plants and determination of endopolyploidy level in plant tissues. These college textbooks are intended for students, teachers and anyone interested in the use of flow cytometry in scientific work with plant cells.

The EFFUSE Teacher's Guide is a practical educational material for primary and secondary school teachers who want to develop environmental awareness with their pupils through field-based learning. It is based on the concept of the EFFUSE project (‘Environment for the future by science education’), which aims to link science, research and education with environmental protection. The manual provides teachers with methodological support for planning and implementing outdoor activities aimed at observing and documenting organisms around the Laborec River and the Uh River. It contains instructions for working with real samples, basic biomonitoring procedures and offers the opportunity to participate in the creation of a virtual laboratory that mirrors the state of the local aquatic ecosystem. Through these activities, pupils will learn to understand the links between human activity and the state of the environment, while learning the basics of how scientists work in the fields of biology and ecology. The guide also motivates teachers to become agents of positive change, inspire the younger generation to be active and engage the community in conservation. It is a challenge and an opportunity to create a space for meaningful learning in line with current trends in environmental and digital education.
