Úvod k praktikám k experimentálnym metódam biofyziky

The university textbook titled Laboratory Techniques and Calculations is designed for the first-year students of the bachelor's degree in Biophysics at the Institute of Physics, Faculty of Sciences, P. J. Šafárik University in Košice. The objective is to equip students with fundamental knowledge and practical skills for the work in a chemical laboratory. It is essential for addressing different biophysical issues and experiments that students will have to solve later. The textbook comprises three principal sections: a theoretical part focused on the calculations, a section dedicated to laboratory work, and the last part offers a brief introduction to spectroscopy. The theoretical part summarizes the basic definitions and equations related to the characterization and preparation of solutions and mixtures. The second, most comprehensive part provides guidance and suggestions for safe and efficient practices in a chemical laboratory. The primary focus is on the manipulation of chemical substances and the use of specific small laboratory instruments and equipment. The fundamental laboratory procedure guides for the selected laboratory works are also provided. As part of a short introduction to spectroscopy, students can become familiar with fundamental spectroscopic concepts and principles. UV-VIS absorption spectrophotometry receives special attention, along with a brief introduction to fluorescence. The textbook is supplemented by various practical and theoretical tasks, as well as numerous web links to further explanatory texts and videos.

Učebný text je primárne určený pre študentov jednoodborového štúdia biológie a všeobecnej ekológie, ako aj odborom učiteľského štúdia v rôznych kombináciách s biológiou. Venuje sa v nich opisu jednotlivých skupín živočíchov, ich morfológiu a anatómiu ilustruje na obrazových materiáloch. K jednotlivým morfologickým a anatomickým štruktúram sa v texte nevyjadrujeme podrobnejšie, nakoľko text nadväzuje na predmet Porovnávacia morfológia živočíchov, kde na úrovni organológie boli tieto najvýznamnejšie štruktúry v rámci prednášok a cvičení detailne vysvetlené a opísané. Rozsah učebného textu nie je veľký, podávame v ňom základné minimum poznatkov, čo je podmienené jednak rozsahom predmetu, ktorý je len jednosemestrový, jednak tým, že ďalšie, špecializované predmety rozširujú spektrum poznatkov napr. na úrovni entomológie, hydrobiológie alebo pôdnej biológie. V zavere niektorých kapitol formulujeme niekoľko cvičných otázok, ktoré si študenti môžu na základe predchádzajúceho textu zodpovedať, s podobnými otázkami sa totiž môžu stretnúť na skúške alebo na štátniciach.

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.

The university textbooks entitled Global Navigation Satellite Systems: GPS, GLONAS, Galileo, Compass present four navigation systems of the GNSS (Global Navigation Satellite Systems): American NAVSTAR GPS, Russian GLONASS, European Galileo and Chinese Compass. The Satellite-Based Augmentation Systems (SBAS) are also briefly explained. They provide regional service in augmenting the reach and support of signals from satellites of the GNSS (GPS, GLONASS, Galileo, Compass). Each satellite navigation system in the frame of GNSS is elucidated in terms of its principles of operation, structure, specificities, applications, and future perspectives.

The university textbook aims to improve the reader’s understanding of the principles and activities of the presented GNSS. The book emphasizes the possibilities of GNSS applications in geodesy and geography. The university textbook constitutes the basic study literature for the class Global Navigation Satellite Systems within the study program Geography and Geoinformatics at the Faculty of Science of the Pavol Jozef Šafárik University in Košice. For a deeper study of the GNSS issue, it is necessary to extend the study materials to include other educational scientific literature dealing with navigation satellite systems and their applications.

The presented work provides basic knowledge of astronomy and astrophysics in a completely new multimedia format. The scope of the knowledge presented is mainly focused on stellar astrophysics and supplemented by cosmology beyond the title of the work.

A new approach in this work is the large proportion of visual materials, graphs, and video clips, contrasted with the brevity of the accompanying text. Such a form of presenting knowledge in this field is unprecedented in Slovakia, and therefore this work can be considered a completely innovative piece. It should be emphasized that the engaging form of the presented knowledge does not come at the expense of its content. The work contains all the necessary information that a physics student, especially one with a pedagogical focus, should master. The work can also be an invaluable aid to teachers in secondary and even primary schools, as well as professional astronomers in popularizing astronomical knowledge.

This suggests that the work covers a relatively wide range of needs at various institutions dealing with astronomy, from universities, through faculties of education and grammar schools, to observatories, planetariums, and astronomy clubs.

The movement of domain walls in ferromagnetic materials is utilized in various magnetic devices for storing, processing, or transmitting signals and information. This mainly includes transformer cores, various sensors, memory devices (e.g., HDDs in PCs), as well as modern spintronic devices such as Racetrack memories, domain wall motion-based electronics, and so on.

This book is intended to serve as a textbook for advanced courses in the field of magnetic materials. It is primarily aimed at students interested in studying magnetic materials, as well as professionals from various fields who wish to understand the basics of domain structure and its changes. It is divided into nine chapters. The first chapter deals with a brief history of the study of domain structure in magnetic materials. The second chapter provides an introduction to the causes and manifestations of magnetic anisotropies. The third and fourth chapters are devoted to the causes of domain structure formation and domain walls. The fifth chapter discusses the structure of domain walls, their potential, and the critical field required for domain wall movement. The sixth chapter is dedicated to magnetization processes, one of which - domain wall movement - is discussed in detail in chapter 7. The eighth chapter contains a theoretical solution for domain wall movement. The final ninth chapter presents a modern method of domain wall movement induced by electric current.

The presented work assumes that the reader has at least basic knowledge in the field of magnetism. Otherwise, the author refers the reader to basic literature (e.g., [2.1 - 2.6]).

Photonics is an application-oriented discipline at the interface of optics, opto-electronics and quantum optics. It includes classical optics extended by the description of physical phenomena and optical devices that rely on quantum (photon) nature of light.
The main objective of the Photonics course is to provide a comprehensive overview of essential optical and photonic phenomena routinely applied in experimental scientific research while working with various light sources (e.g. in the field of biophotonics). The first chapters are devoted to the description of light at different levels. The logical order of subsections in this part corresponds to the structure of the textbook: B. E. A. Saleh, M. C. Teich, Fundamentals of Photonics. The following chapters contain a description of laser operation and an overview of selected optical instruments and their applications.
The body text is complemented by practical notes on the use of theoretical knowledge during daily work in the laboratory. The course of Photonics requires a basic knowledge of mathematics, electromagnetism and optics, and thus it is recommended to students who previously passed through the courses of the Bachelor's program in Physics.

Nuclear Magnetic Resonance (NMR) is currently a widely used analytical tool that finds application in many fields of science and technology. The broadening of its practical use brings with it the necessity to create educational texts appropriate to the given scientific discipline.

This university textbook is intended for students of biology and serves as a supplement to the study materials for the advanced master's course "Biology of Lichens." At the same time, it represents a useful resource for master's and doctoral students involved in research, helping them interpret NMR spectra and present basic theoretical concepts.

The textbook briefly describes the important aspects of each NMR spectroscopic technique without delving excessively into the physical principles of individual methods or complex mathematical analyses. In this edition, the structures of lichen metabolites have been included, which students will isolate, purify, and identify using various analytical methods during practical exercises. An entire chapter is dedicated to a detailed description of solving the NMR spectra of isolated metabolites, with each step in elucidating the structures of both known and unknown metabolites explained in detail. The solved tasks are followed by numerous unsolved examples, including high-resolution 1D and 2D NMR spectra of metabolites, intended to further develop the acquired knowledge and skills of students and doctoral candidates in structure elucidation using NMR spectroscopy.

The aim of writing the university textbook "Selected Heterocyclic Compounds" was to create a study aid for students of the Organic Chemistry program, which provides essential information in a clear format for the subject of Heterocyclic Compounds. In selecting the content of the textbook, the goal was to present basic information about the chemistry of the most significant heterocycles. Given that the summary of chemical knowledge about heterocycles is vast, it was not possible to include all heterocyclic compounds in the content.

The intention was for readers to orient themselves in the field of heterocyclic compounds. Separate chapters included in the content address the nomenclature of heterocycles, basic chemical properties of individual heterocycles, their synthesis and reactions, the occurrence of heterocycles in nature, and their practical applications (medications, dyes, pesticides, detergents, etc.).

In 2018, the Student Scientific Conference was held on April 18, 2018, in 16 sections covering biology and ecology, chemistry, physics, geography, mathematics, computer science, and their subject didactics. There were 110 registered contributions from bachelor's and master's students. Additionally, eight high school students participated outside of the competition; these students already visit our alma mater at a young age, work in our laboratories, and prepare for further studies under the guidance of our enthusiastic teachers. The day also included a programming competition and the IHRA competition in three categories, where students from PF UPJŠ competed alongside pupils from elementary and secondary schools.

The abstracts of the Student Scientific Conference contributions convincingly demonstrate that PF UPJŠ students study their field not only theoretically but also actively engage in solving partial scientific problems that are part of the research goals at PF UPJŠ institutes. This collection provides an overview of scientific activity at the faculty, which we believe will be interesting for the broader public as well.
