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.

A significant part of inorganic chemistry is coordination chemistry, which deals with coordination compounds. Coordination compounds are numerous because they arise from the combination of central atoms, mostly metals, with ligands, and every organic compound is a potential ligand. This is confirmed by a recent report that American scientists M. Brookhart, C. Schauer, and their colleagues from universities in North Carolina and Washington described the preparation of a rhodium complex with methane as a ligand.

This textbook is based on the long-term experience of the author in teaching and testing this subject. The subject is well-covered in several textbooks of varying difficulty in English; their partial list can be found by readers in the list of used literature at the end of this textbook. On the other hand, in Slovak language, coordination chemistry issues are only marginally covered in several textbooks focused more on general inorganic chemistry but lack a comprehensive view on this topic. From this follows the goal of this proposed textbook - to cover the lack of study literature in this area for Slovak language.

Proceedings of Abstracts from Contributions by Participants of the Student Scientific Conference at the Faculty of Science, UPJŠ in Košice, Held on April 26, 2017

This is the fifth edition of the proceedings from the Student Scientific Conference (ŠVK) at the Faculty of Science, Pavol Jozef Šafárik University in Košice. We are pleased that ŠVK has become an integral part of faculty life and a showcase for the quality of education provided. In 2017, ŠVK took place as part of the traditional Science Days on April 26, 2017. 105 students from the Faculty of Science presented their work. Contributions were organized into 15 sections, supplemented by an open programming competition involving 17 students and the final round of the IHRA competition, which included 27 teams from across Slovakia.

The abstracts in this proceedings demonstrate that students at the Faculty of Science, UPJŠ, acquire knowledge and skills in their field not only through theoretical study of disciplines but also through active engagement in solving partial scientific problems aligned with research goals at the faculty’s institutes. These abstracts also provide an overview of the faculty’s scientific activity, which we believe will be of interest to the broader public.

Students studying biology as the single-subject or as a part of two-subject programs on various faculties of sciences are often encountered with the problem, how to limit the topics in the subject Human anatomy. This List of anatomical terms is aiming to help the non-medical students to get acquainted with the extensive anatomical nomenclature and to optimize the number of anatomical terms, which should be memorized, to preserve the sufficient capacity of the students for another knowledge of the field of systemic, comparative, developmental and functional anatomy. The emphasis on the arrangement of individual anatomical terms into the logical units supports the hierarchical view on the architecture of the human body.

Despite the common opinion, anatomical nomenclature represents a framework, which is during the further study gradually enveloped with the knowledge of more or less related disciplines concerning with the human body and its biological processes. Moreover, besides this ambition, which exceeds the area of the human anatomy, this List of anatomical terms continues the long tradition with respect to the valid Latin and Slovak anatomical terminology.

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.

Učebný text Počítačová fyzika I obsahovo pokrýva problematiku prednášanú v rovnomennom kurze na bakalárskom stupni študijného programu Fyzika a v kurze Aplikácia numerických metód na bakalárskom stupni študijného programu Aplikovaná informatika. Text nadväzuje na základný kurz numerických metód so zameraním na výklad základných princípov počítačového riešenia niektorých typických fyzikálnych úloh. Zahŕňa jednak oblasť deterministických metód riešenia problémov modelovaných obyčajnými a parciálnymi diferenciálnymi rovnicami ako aj oblasť stochastických Monte Carlo simulácií. Kurz Počítačová fyzika I vytvára základ pre ďalšie štúdium pokročilejších počítačových metód prednášaných na magisterskom stupni v rámci predmetu Počítačová fyzika II. V súčasnosti je používanie počítača ako nástroja riešenia reálnych fyzikálnych úloh, a v prípade študentov ako nástroja vypracovania ich záverečných bakalárskych či diplomových prác, takmer nevyhnutnosťou. To viedlo k vzniku množstva užívateľsky orientovaných softvérových balíkov v rôznych prostrediach pre riešenie širokej škály problémov. Avšak, bez dôsledného pochopenia fungovania jednotlivých počítačových techník sú tieto programy čiernymi skrinkami s množstvom úskalí a rizík pri ich používaní. Preto tento text kladie dôraz na pochopenie silných aj slabých stránok jednotlivých metód a predpokladov ich úspešného použitia.

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.
