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.

In these university-level textbooks, we present the fundamental concepts of networks and graph theory. We explore breadth-first and depth-first graph searching. We present static and dynamic network models. We describe the issue of detecting overlapping and non-overlapping communities in directed and undirected networks. Various approaches to anomaly detection in networks also form an important part of this textbook. The final chapter is dedicated to spectral clustering, which plays a significant role in data mining in network graphs for various application domains.

These textbooks are suitable for first and second-year university students in computer science programs. The study materials are also suitable for students in non-computer science fields, with the aim of improving their knowledge and practical experience in computer science-related areas, and provide an opportunity for students to find employment in IT companies to solve practical tasks.

Bibliographies provide basic scientific information, illustrate quality and intensity of research in a particular topic, area, or time, and thus help build a cultural-historical perspective of society’s appreciation of knowledge and education. Here we provide a bibliography of herpetological research in the region of Slovakia between the years 1791 and 2017. We collected 2,183 references authored by 1,453 different authors and covering all species of amphibians (18) and reptiles (13) occurring in Slovakia and, in addition, amphibian and reptile taxa occurring in 94 other countries.

Most of the contributions were published in popular magazines and non-indexed journals, while only about 12% of all references represent scientific articles from journals indexed in relevant scientific databases. The extensiveness of study on amphibians and reptiles has varied among different periods within the selected time frame. However, an obvious intensification in the field of herpetology can be observed, especially during the second half of the 20th century. While there have only been few professionals specialized in herpetology, an important role in promoting the research and conservation of amphibians and reptiles in Slovakia has been played by non-governmental organizations and hobbyists. The most frequent type of herpetological data in the referenced literature comes from faunistic research, followed by conservation and general information on herpetofauna, with the majority of published articles in indexed journals coming from the fields of palaeontology, phylogeography, and population genetics.

The presented bibliography is the first step towards building a solid base for future systematic herpetological research in the country and Central Europe.

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.

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.

This book addressed the inquiry-based learning and teaching with the support of geospatial technologies. Today, geospatial technologies are influencing geography teaching learning, particularly in secondary education. Theoretical framework gives the reader the insight to inquiry-based learning, with special focus on inquiry in geography. The one-by-one step of inquiry is analysed in detail. The major part of the book presents the eleven models of geography lessons, representing the subject content of physical, human and regional geographies, various levels of inquiry and use of different geospatial technologies. The readers are acquainted with the use of geographic information system (particularly Google Earth and ArcGIS online), web portals, webGIS, open data, mobile applications and new forms of 3D cartographic visualisation (virtual reality, 3D print, dynamic 3D map) in teaching geography. The lesson models were tested with the students to be geography teachers in school year 2021/2022. This books serves as resource mainly for undergraduate teacher students and in-service geography teachers.

Pojem integrálu je jedným z najvýznamnejších pojmov v matematike vôbec. V naj- primitívnejšej podobe ho používali už starí Gréci pri tvorbe euklidovskej geometrie. No až po Descartovom diele o analytickej geometrii z roku 1637 mohli matematici začať považovať integrál za predmet analýzy. Descartova práca pripravila podmienky pre objav infinitezimálneho počtu Leibnizom a Newtonom okolo roku 1665. V tom čase vznikol veľký spor o prvenstvo tohto objavu, čo rozdelilo učencov Nemecka a Anglicka do dvoch bojujúcich táborov, z ktorých každý fandil svojmu favoritovi. Dnes vieme, že Newtonova práca o fluxiách a fluentoch bola o niečo skoršia, ale Leibnizovo označenie a prístup sa v matematickom svete ujali viac a symboly R a d sa používajú dodnes. Stručný prierez históriou integrálu bude uvedený v Kapitole 1.

Dnes existuje celá hromada skrípt, učebníc, či kníh venovaných výkladu pojmu integrál. Preto pred prvú otázku, či napísať ďalší text o tejto problematike, je postavený každý potenciálny autor. Nás ku kladnej odpovedi na túto otázku doviedla požiadavka študentov nájsť v určitej ucelenej podobe prednášanú problematiku časti zimného semestra druhého ročníka. Druhou motiváciou je trochu odlišný prístup k problematike. Ak si totiž uvedomíme, ktoré metódy sa zvyčajne používajú pri riešení úloh a zís- kavaní rutiny z určitého integrálu, ide hlavne o Newtonovu-Leibnizovu formulu a častokrát na výpočet určitého (Riemannovho) integrálu pomocou definície nezostáva veľa času. Preto sme zaradili pojednanie o Newtonovom integráli v Kapitole 2, ktorý reflektuje túto skutočnosť a má priamy súvis s neurčitým integrálom, ktorého rôznym metódam výpočtu sa venuje relatívne veľa pozornosti v predchádzajúcom semestri. Až za tým v Kapitole 3 vybudujeme teóriu Riemannovho integrálu, uvedieme kritériá jeho existencie, triedy integrovateľných funkcií, základné vlastnosti a nakoniec vzťah s Newtonovým integrálom. Otázky prevažne geometrických aplikácií riešime v Kapitole 4 a v poslednej kapitole sa venujeme rozšíreniu Riemannovho integrálu pre neohraničené funkcie a neohraničené intervaly.
