The university handbook Elementals of Population Geography and Demography - Part I, as an introduction to population studies, is primary study material for students of the geography study program, as well as for students of the Information Systems in Public Administration study program at the Pavel Jozef Šafárik University in Košice, but also for the wider public interested in about population phenomena and their spatiality. Among other things, the handbook offers the latest population reports in the world and its regions. The aim of the handbook is to introduce young geographers to the basics of population research, which includes the most frequently used tools and methods in geographic analysis. The first part of the handbook contains an introduction to the scientific disciplines of population geography and demography with an overview of basic sources of demographic data. The next part discusses the issue of anthropogenesis, i.e. the development of humans from our ancestors and the spatial spread of humans across our Earth. Part of this part is the recent development of the world population and changes in the size and distribution of the global population over time. The last part analyses how the population is distributed in the world and in relation to the geographical components of the space.

Tento učebný text je určený poslucháčom prvého ročníka študijného odboru 76–12–8 „Učiteľstvo všeobecnovzdelávacích predmetov“ v kombináciách s matematikou. Je vyhotovený na základe prednášok autorov a ich viac ako desaťročných skúseností z výučby tohoto predmetu na PF UPJŠ. Pri jeho písaní sa autori snažili zohľadniť špecifickosť učiteľského štúdia matematiky. Predkladaný učebný text nebol písaný pre nedostatok učebníc matematickej analýzy. Dôvodom pre jeho napísanie boli zistenia autorov, že poslucháči nemajú zo strednej školy dostatočné skúsenosti v práci s odbornou literatúrou, ťažkosti mnohým spôsobuje (najmä v prvých semestroch) čo i len trochu odlišný výklad, nie zriedka aj zmena v označovaní, čím im uniká podstata študovanej problematiky. Autori textu si nekládli za ciel byt originálni. Ich snahou bolo urobiť taký výber tém, aký je nutný pre budúceho učiteľa matematiky a zvoliť takú metódu výkladu, ktorá je podla ich názoru vhodná pre poslucháčov prvého ročníka. Dobré zvládnutie učiva (rozšírenie matematického aparátu a s tým súvisiace možnosti uplatnenia iných dokazovacích metód ako aj získanie potrebných početných schopností) predpokladá použitie aj ďalších literárnych prameňov (učebníc, zbierok úloh) podla odporúčania vyučujúceho.

One of the fundamental characteristics of the magnetic state of ferromagnetic materials is the existence of a domain structure. The university textbook "MAGNETIC DOMAINS: SPECIAL PHYSICAL PRACTICE 1" is intended primarily for students of the Master's programme in Physics of Condensed Matter FKLm and for the PhD programme in Progressive Materials PMd within the profile subject Special Practice 1 at the Institute of Physical Sciences of the Faculty of Sciences of the Pavol Jozef Šafárik University in Košice.  The textbook is divided into seven chapters. The first chapter is devoted to the basics of domain theory, including the history of domain observation and the specification of different types of energies in ferromagnetic body. The second chapter presents the relationship between domain structure and magnetisation processes in ferromagnetic materials The third chapter describes the different types of domain-wall interactions with the defect. The fourth chapter illustrates examples of domain structure in selected ferromagnetic body such as grain oriented and non-grain oriented electrical steels, amorphous and nanocrystalline ribbons. The fifth chapter summarises an overview of the different experimental methods used to visualise the domain structure and their advantages or disadvantages with respect to the structure of ferromagnetic materials. The last two chapters, the sixth and the seventh, are devoted to specific experimental tasks for observing the domain structure of a selected polycrystalline sample using the optical microscope Bitter powder method and the MFM (magnetic force microscopy) method. During the preparation of this undergraduate text, its individual parts were developed using the foreign language literature listed in the recommended references.

The presented scripts were created in an effort to update and especially clarify the tasks that are solved in the basic practical exercises in biochemistry students of the 2nd and 3rd year of the bachelor's degree in chemistry, biology and their combinations with other disciplines. Most of the tasks come from the original scripts "Podhradský, Mihalovová: Praktické cvičenia z biochémie, Košice 1989".

Some of them have been modified to a greater or lesser extent and adapted to current conditions in the laboratory. New tasks were also added, such as those dedicated to nucleic acids. The scripts are thematically divided into six separate units, each of which consists of several tasks. The names of the units correspond to the nature of the biomacromolecules, which form their central theme. Theoretical introductions at the beginning of the unit are newly constructed and their main goal is to provide a brief overview of the basic biochemical methods used in the study of biomacromolecules.

These scripts are intentionally only available in electronic form. The reason is the effort to continuously update and modernize individual tasks according to the changing possibilities of our laboratory. We hope that the scripts will fulfill their role and that students will have sufficient theoretical knowledge and practical skills in the field of basic biochemical methods after completing these laboratory exercises.

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.

Crystallography deals with discerning the arrangement and bonding of atoms in crystalline solids. Almost immediately after their discovery, X-rays began to be used to study the internal structure of substances. The first chapter of this textbook deals with the basic concepts of crystallography. At the beginning, crystalline solids are characterized. In the next section, the basic types of bonds and their characteristics are briefly presented. The main subject of this chapter is the interpretation of basic concepts such as symmetry operations, translational periodicity, grid, elementary cell. Spatial lattices and crystal systems are presented. At the end of this chapter, attention is paid to the description of individual types of defects in crystal structures. In the second chapter, the Bohr model of the hydrogen atom is presented. Individual quantum numbers and their meaning are given. Next, energy levels and allowed transitions within an atom with multiple electrons are described. The second chapter concludes with the characterization of the basic absorption and emission processes. The third chapter is devoted to the production of X-ray radiation and its properties. Sources of X-ray radiation and a description of their operation are presented. Interaction of X-ray radiation with matter, absorption and detection of X-ray radiation are the subject of the last part of this chapter.

Práca s učebným textom predpokladá primerané znalosti z oblasti fyzikálnej chémie, fyziky a biológie, bez ktorých je orientácia v predkladanom študijnom materiáli zložitá. Solídne znalosti z matematiky sú nevyhnutné a pomáhajú pri pochopení problémov koloidnej chémie. V skriptách, ktoré sa členia na jednotlivé kapitoly, po klasifikácii a charakterizácii disperzných sústav sa najprv rozoberajú optické a molekulovo-kinetické vlastnosti. 
Mimoriadne veľký medzifázový povrch, ktorý je charakteristický hlavne pre koloidne disperzné sústavy, pripisuje zvlášť dôležitú úlohu javom, ktoré prebiehajú na fázovom rozhraní, t.j. povrchovým javom. V súvislosti s týmto poznatkom diskutujú sa vlastnosti mobilných fázových rozhraní a fázového rozhrania tuhá látka/plyn a tuhá látka/kvapalina. Významná je následne zaradená kapitola o elektrických vlastnostiach disperzných sústav. Táto kapitola je tesne spojená s otázkami vzniku, štruktúry, stability a deštrukcie disperzií; pozornosť sa venuje predovšetkým koloidným sústavám. Neoddeliteľnou súčasťou je aj kapitola, ktorá popisuje reologické vlastnosti disperzných sústav. Ďalšie kapitoly uvádzajú jednotlivé typy disperzných sústav.

Tento vysokoškolský učebný text je určený najmä študentom chemických a ekologických odborov na Prírodovedeckej fakulte Univerzity P. J. Šafárika v Košiciach. Nekladie si za cieľ vyčerpávajúco rozoberať do detailov celú problematiku, lebo o nej pojednávajú monografie nielen z koloidnej a makromolekulovej chémie, často možno nájsť detailné rozpracovanie aj v základných učebniciach fyzikálnej chémie.

The structure of the animal body is extremely varied. Each species has its distinctive morphological features, which bears as a testimony to long-term development and belonging to the developmental lineage. At the same time, the body has been tested for a long time by natural conditions, resulting in unique adaptations to the environment and life strategy. Despite this admirable variety - which includes both recent and fossil animals and which we have far from mapped – a comparison of body parts brings knowledge we can generalize: the main building principles, and boundaries within which phenotypic diversity is realized.

Comparative animal morphology today uses the latest methodological material and knowledge from other disciplines, from genetics, molecular biology and experimental embryology, through progressive imaging methods (e.g. electron microscopy, computer micro-tomography) and the possibilities of subsequent software processing of image material (measurement, staining, etc.) to the view of physics, chemistry, statics and geometry on the structures (to nanostructures) of the living body. Detailed knowledge of historical and contemporary conditions on Earth is an important interpretative context in the study of animal morphology. Surprisingly, the knowledge accumulated after centuries of research is now rapidly supplemented by new knowledge, and often the traditional knowledge is subsequently reinterpreted. Finally, and no less important, in studying animal (and human) morphology, we learn surprising knowledge about ourselves.

The author of the presented textbook had the ambition in a simplified form to introduce the reader, especially the student of biological studies, into a dynamic and fascinating scientific discipline, as the current comparative animal morphology is.

Elektrochémia je veda, ktorá študuje iónové systémy a také procesy alebo javy, ktoré prebiehajú na hranici iónových systémov s kovmi alebo s polovodičmi. V súčasnom štádiu rozvoja môžeme elektrochémiu rozdeliť podľa jej zamerania na dve oblasti. Prvá z nich - ionika - sa zaoberá vlastnosťami iónových sústav (roztoky, taveniny, tuhé elektrolyty). Druhá oblasť - elektrodika - sa zaoberá javmi na fázovom rozhraní elektróda/iónová sústava.

Ionika aj elektrodika skúmajú rovnovážne aj nerovnovážne javy a procesy. Výskumom vlastností iónových sústav za rovnovážnych podmienok získavame informácie a predstavy o štruktúre a zložení roztokov a tavenín elektrolytov, ako aj tuhých elektrolytov, kým merania za nerovnovážnych podmienok referujú o elektrickej vodivosti iónových sústav. V oblasti elektrodiky sa štúdiom rovnováh na rozhraní elektróda/roztok (prípadne tavenina) zaoberá elektrochemická termodynamika. Meranie rýchlostí procesov prebiehajúcich na tomto fázovom rozhraní a vysvetlenie zákonitostí, ktorými sa tieto procesy riadia, je predmetom kinetiky elektródových procesov alebo elektrochemickej kinetiky.

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.
