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.

This electronic material provides the basic principles of creating a systematic nomenclature of organic compounds, from the simplest hydrocarbons to the more complicated nomenclature of carbohydrates. For some groups of derivatives, alternative ways of generating system names are also mentioned, as well as the most common trivial names that are still in use in the literature and in practice, in some cases being the characteristic (dominant) ones. In the introductory section, the basic rules to be respected when writing names of organic compounds are discussed. This document is intended primarily for interdisciplinary undergraduate and graduate students as support material for the courses Organic Chemistry and Selected Chapters in Organic Chemistry and Biochemistry. In the final section of this document, solved examples are given so that the student can check how the rules for forming the names of organic compounds have been understood.

V tomto učebnom texte sú spracované základy fenomenologickej termodynamiky v rozsahu, ktorý je prednášaný v štandardných kurzoch teoretickej fyziky na bakalárskom stupni študijného programu Fyzika. Mierne zredukovaný rozsah sa prednáša tiež na všetkých medziodborových študijných programoch v kombinácii s fyzikou. Časová dotácia pre jednotlivé kurzy bola v posledných rokoch mierne zredukovaná, čomu zodpovedá náš výber a rozsah jednotlivých tém. Našou primárnou snahou bolo dostatočne fundovane vysvetliť kľúčové pojmy a zákony termodynamiky, ktoré sú nutné pre zvládnutie ďalších teoretických fyzikálnych kurzov na magisterskom stupni štúdia (napr. Štatistická fyzika, Fyzika kondenzovaných látok, Kvantová teória tuhých látok, Kvantová teória magnetizmu atp.). Kniha tiež prestavuje nutné minimum vedomostí, ktoré sú nevyhnutné pre štúdium ďalších aplikácií termodynamiky v biofyzike, biológii, chémii, prípadne v inžinierskych odboroch. Porozumenie jednotlivých častí, ale aj textu ako celku vyžaduje ovládanie základných pojmov termodynamiky na úrovni kurzu Všeobecnej fyziky a znalosti v rozsahu štandardného univerzitného kurzu matematiky. Jednotlivé témy sú spracované s maximálnym dôrazom na koncepčnosť a matematickú rigoróznosť. Tak ako v iných teoretických disciplínach, aj v termodynamike vyžaduje pochopenie kľúčových pojmov a zákonov paralelné riešenie praktických úloh k jednotlivým témam, čo sa prirodzene deje na numerických cvičeniach, ktoré sú súčasťou kurzu. Pre čitateľov, ktorí nie sú univerzitnými študentami odporúčame ako cvičebnicu knihu R. Kubo: Thermodynamics, North Holland Publishing Company (1968). Tak ako každá kniha, aj tento text nie je dokonalý a určite sa v ňom nájdu nedostatky rôzneho charakteru. Budeme preto vďační každému čitateľovi za konštruktívne obsahové i formálne pripomienky. Na záver chceme poďakovať Janke Jaščurovej za jazykové korekcie a Ing. Mgr. Viliamovi Štubňovi za technickú podporu pri spracovaní obázkov v tomto učebnom texte a tiež za korekcie textu.

The proposed text focuses on the history of studying biology, medicine, and pharmacy as scientific disciplines from prehistoric times through antiquity, the Middle Ages, and the modern era. The text chronologically organizes the most significant figures in the history of biological scientific disciplines, outlines key characteristics of major historical discoveries, and reevaluates their significance from the perspective of 21st-century science.
The educational text is chronologically divided into the most significant periods of civilization development. The last two completed centuries—the 19th and 20th—are subdivided into major life science fields due to the unprecedented growth of biological disciplines and the resulting volume of acquired information.
Since it can sometimes be challenging in science to define what constitutes the past versus the present of a particular discipline, we have excluded significant biological discoveries from the early 21st century, which are typically regarded as the “present” of biology.

Tieto „Návody na cvičenia“ prezentujú stručný prehľad bežne používaných metodík i progresívne metodiky napr. s použitím kvapalinovej chromatografie a fluorescenčného mikroskopu. Jednotlivé úlohy sa selektovali na základe výskumného zamerania Katedry botaniky PF UPJŠ v Košiciach z hľadiska „stresovej fyziológie“. Niektoré úlohy je tiež možné využiť v rámci predmetu „Ekológia rastlín“. Ako modelová rastlina pre jednotlivé úlohy sa typicky používa rumanček kamilkový z dôvodu dlhoročnej histórie jeho výskumu na Katedre botaniky PF UPJŠ a jeho nenáročnosti na kultiváciu v laboratórnych podmienkach. Jednotlivé kapitoly prezentujú aj stručný význam sledovaných parametrov, princíp stanovenia a metabolizmus (vznik alebo odbúravanie) s cieľom naznačiť ich vzájomný kontext, keďže stanovenie individuálneho parametra nemôže poskytnúť všeobecnejšiu výpoveď o celkových príčinách a dopadoch pozorovanej zmeny (ale naopak, môže poskytnúť predpoklad pre preverenie hypotézy na úrovni iných parametrov...). Pre hlbšie štúdium jednotlivých problematík existuje dostatok kvalitných zahraničných monografií a prehľadových (tzv. „review“) článkov.
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.

This textbook is intended for master's degree students and is a follow-up to the Computational Physics I course studied at the bachelor's level. The content of the textbook Computational Physics II focuses on stochastic methods of solving physical problems, mainly on Monte Carlo (MC) simulation of many-particle systems. The focus on this computationally intensive approach is motivated by the gradual increase in the computing capacities of ordinary computers as well as the introduction of high-performance computing clusters. This has led to significant progress in the development of new simulation techniques, thanks to which MC simulations have found application in various areas of research and application practice. Considering the main research focus of the department, this text is particularly devoted to the presentation of basic and more advanced MC simulation techniques applied to a simple Ising spin model in order to investigate its magnetic, thermodynamic and critical properties. The next part is devoted to MC simulations of random processes. It focuses on the simplest but also the most basic random walk process and demonstrates its applications in financial analysis and the solution of a quantum system described by the time-dependent Schrödinger equation. The last part is dedicated to the basics of molecular dynamics, applied to simulating the classical movement of atoms in a given force field. By mastering the problems addressed in this course, students will obtain a potential tool for working out of their diploma theses, or a methodology useful for their further scientific and research practice in the field of investigating of complex systems. The lectured topic is subsequently exercised in the form of preparing projects implemented in the freely distributable software Octave, which is easy on the user's programming skills and which students have the opportunity to familiarize themselves with in the previous study.

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.

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.
