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.

Organic chemistry is the chemistry of carbon. Organic compounds in the form of large molecules (macromolecules), such as nucleic acids, proteins, carbohydrates, and lipids are the basic elements of living organisms. This study material is created for non-chemistry students, especially students of biology. Most of these students have little or no knowledge of organic chemistry. Therefore, we proceed from the basic principles of organic chemistry to biochemistry.

The basic principles of organic chemistry and biochemistry are briefly summarized in individual chapters, but the main content consists of tasks for practising basic knowledge. To check the correctness of solving the tasks, the correct solutions are also given. The importance of this study material lies in the fact that students will get additional study material that they will use in studying the subject Basics of Chemistry.

Nanotechnology represent the fastest developing science in the present. They are based on the technologies that enable the matter manipulation at atomic level. Nanotechnology offer prepartion of the new materials with unknown and very specific properties and functions.Recent nanotechnology still stay in formative phase of their development. But more and more they are visible with nano-specific phenomenons in the fundamental control of the properties as well mater behaviour. This is quite possible that without nanotechnology will not work any science to the future, moreover that science will not exist anymore. Nanotechnolgy will give a chance and force to transform world to more environmental and comfortable. Expected is expansion of the nanotechnolgy to molecular nanosystems – heterogenous nets, in which molecules and supramolecules work as the nanodevices. The computers and robots will be reduced to the small and ultrasmall dimensions. In medicine will foremost the application of nanotechnology in genetic therapy and elimination of ageing. Nanosurgery will work at molecular level, cancer cells will be identified early and filtered , then substituted with healthy and unchanged. It is necessary to inform university or high school students  about principles of nanotechnolgy, preparation of the nanostructures, functionality of them and to offer full representation about molecular systems and nanodevices; the methods of nanostructures characterization and about application in miniaturized systems.

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.

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.

Over the past fifteen years, the course on ’Exactly Solvable Models in Statistical Physics’ has become an indispensable ground of the study programme ’Theoretical Physics’ at Faculty of Science of Pavol Jozef ˇSaf´arik University in Koˇsice. At first, the course based on the first edition of this textbook was intended for undergraduate students only, however, I have later prepared follow-up course taught at a postgraduate level on demand of several ambitious students who wished to continue in studying this exciting research field. It is already more than decade when our students enrolled in the study programme ’Theoretical Physics’ graduate from ’Introduction to Exactly Solvable Models in Statistical Physics’ at a master level and ’Exactly Solvable Models in Statistical Physics’ at a postgraduate level. Of course, it was necessary somehow to rearrange topics for the courses of undergraduate and postgraduate students. More specifically, a few more challenging topics concerned with exact solutions of 2D Ising model (chapter 3) were moved to a more advanced course intended for the postgraduate students, while an introductory course intended for the undergraduate students was contrarily supplemented with a few new topics requiring the second edition of this textbook. The second edition of this textbook thus contains a completely new chapter 4 devoted to the exact solution of the Ising model on the Bethe lattice using the method of exact recursion relations, while the chapter 5 was supplemented by exact results for ground state of a few frustrated Heisenberg spin models using the variational method. It is my hope that the next edition of this textbook will come soon and it will involve all topics specifically taught within the postgraduate course as well.

Zriadenie cvičebne fyziológie rastlín na Katedre botaniky PF UPJŠ v Košiciach v roku 1969 bolo spojené s menom Ing. Štefana Kocúrika, CSc. (1923 - 2006), ktorý spracoval aj prvé „Návody na cvičenia z fyziológie rastlín“ (Košice 1972, 1976). Od roku 1980 sa využívala príručka doc. RNDr. Karola Erdelského, CSc. a Ing. Fridricha Friča, DrSc. „Praktikum a analytické metódy vo fyziológii rastlín“ (Bratislava 1980).
Po zvýšení počtu študentov, sa v roku 1991 ukázalo aktuálnym vydať „Návody na cvičenia z fyziológie rastlín“ v záujme lepšej prípravy a efektívnej organizácie práce na cvičeniach. Doc. RNDr. A. Košturiak, CSc. svojimi podnetnými radami prispel k podstatnému rozšíreniu úvodnej časti návodov, za čo sú mu autori zaviazaní vďakou.
Pre štvrté vydanie sme inovovali a modernizovali niektoré úlohy a zohľadnili sme možnosti inovovanej praktikárne. Výber úloh sme prispôsobili aktuálnemu rozsahu cvičení jednotlivých predmetov fyziológie rastlín v bakalárskych a magisterských študijných programoch biológie a ekológie. Ide o predmety: Fyziológia rastlín, Metabolizmus rastlín, Minerálna výživa rastlín, Rast a vývin rastlín a Ekológia rastlín. Niektoré úlohy sú vhodné tiež pre stredoškolské pokusy. Výber tém ovplyvnila výskumná orientácia nášho pracoviska na sekundárny metabolizmus, ekofyziológiu a liečivé rastliny. V návodoch sa spravidla pridržiavame jednotiek SI sústavy, niekedy uvádzame iné zaužívané jednotky.

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.

Tento vysokoškolský učebný text je určený študentom chemických a ekologických odborov na Prírodovedeckej fakulte Univerzity P. J. Šafárika v Košiciach a má poslúžiť ako pomôcka pre experimentálne cvičenie z koloidnej chémie. Koloidná chémia je významnou súčasťou teoretického základu chemických vied, patrí medzi novšie interdisciplinárne odbory prírodných vied. Spája poznatky z oblasti fyzikálnej chémie, fyziky a biológie, pričom využíva aj solídne znalosti z matematiky a ďalších vedných odborov. Pri pochopení problémov koloidnej chémie sú často nevyhnutné aj experimenty, ktoré modelujú predstavy o priebehu javov a zákonitostí, ktorými sa tento vedný odbor zaoberá. Preto je pre zvládnutie učebnej látky z koloidnej chémie také dôležité a podstatné aktívne absolvovanie experimentálneho cvičenia. Pri výbere úloh pre tieto skriptá bolo treba rešpektovať aj značné obmedzenia dané možnosťami laboratórne prístrojového a materiálového vybavenia nášho pracoviska. Napriek tomuto obmedzeniu však môžu študentom ilustrovať základné teoretické fyzikálno-chemické princípy koloidne disperzných sústav, a čo je dôležité – ich pochopenie môže prispieť k porozumeniu niektorých dôležitejších zvláštností koloidných javov.
