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.

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.

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.

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 present textbook deals with exactly solved models and their diverse applications in several branches of physics such as mathematical physics, statistical physics, condensed matter physics and so on. Exactly soluble models are currently considered as an inspiring research field in its own right, which regrettably requires a considerable knowledge of sophisticated mathematics. Accordingly, my primary ambition was to provide an intro- ductory course for undergraduate students that would cover the simplest exactly solved models, whose rigorous solutions are available even after modest calculation. The present textbook should be therefore regarded as an auxiliary graduate-level textbook, which should serve as the student’s guide on this beautiful but surely intricate subject.
Even although I attempted to write largely self-contained textbook for undergraduate students, it is worthy of notice that the course on Exactly Solvable Models in Statistical Physics demands essential knowledges from the quantum mechanics, statistical physics, phase transitions and critical phenomena, which are its indispensable prerequisities. The most crucial fundamentals of these theories are briefly recalled in introductory remarks just for remembering and not for substituting those comprehensive courses. The rest of this textbook is entirely devoted to exactly solved lattice-statistical models with the main emphasis laid on their possible applications in the condensed matter physics. It is the author’s hope that the presented exact solutions are detailed enough in order to be easily followed by undergraduate students even without a support of tedious proofs, cumbersome theorems, longer argumentations, or obvious facts. This rather necessary compromise has of course a certain unadvisable impact on ’exactness’ of the presented solutions.
Finally, it is worthwhile to remark that the present textbook makes just a slight introduction into the simplest exactly solvable models and thus, the interested reader is referred for the follow-up study to several excellent books on exactly solved models quoted in the bibliography list on the next page. Note that the listed books were the major knowledge sources used by creating this textbook and they might be regarded as more advanced literature on this exciting research field.

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.

The aim of these study texts is to provide students in the second and third levels of higher education with specific guidance on processing 2D diffraction data, performing phase analysis from X-ray diffraction data, and refining microstructural parameters of identified phases using the Rietveld refinement method.
This guide is designed in the form of real-world tasks from materials research and leads the reader step by step through the processes of processing, evaluating, and interpreting the measured data. For this purpose, freely accessible programs such as Fit2D, QualX, POV-Ray, and GSAS II will be used, as well as a freely downloadable commercial program (Diamond) that allows for task execution in demonstration mode. Phase analysis will be conducted exclusively using the freely distributable crystallographic database Crystallography Open Database (COD).

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.
