Qauntum theory of magnetism

E-book

Michal Jaščur

This is a supporting text for the undergraduate students interested in quan- tum theory of magnetism. The text represents an introduction to various theoretical approaches used in this eld. It is an open material, in the sense that it will be supported by appropriate problems to be solved by student at seminars and also as a homework.

The text consists of four chapters that form closed themes of the in- troductory quantum theory of magnetism. In the rst part we explain the quantum origin of the magnetism illustrating the appearance of the ex- change interaction for the case of hydrogen molecule. The second chapter is devoted to the application of the Bogolyubov inequality to the Heisenberg model and it represents the part which is usually missing in the textbooks of magnetism. The third chapter deals with the standard spin wave-theory including the Bloch and Holstein-Primakoff a approach. Finally, we discuss the application of the Jordan-Wigner transformation to one-dimensional spin-1/2 XY model.

The primary ambition of this supportive text is to explain diverse math- ematical methods and their applications in the quantum theory of mag- netism. The text is written in the form which should be sufficient to de- velop the skills of the students up to the very high level. In fact, it is expected that students following this course will able to make their own original applications of the methods presented in this book.

The reading and understanding this text requires relevant knowledges from the mathematics, quantum and statistical mechanics, and also from the theory of phase transitions. It is also expected that students are familiar with computational physics, programming and numerical mathematics that are necessary to solve the problems that will be included in the MOODLE educational environment of the P.J. Safarik University in Kosice.

Finally one should note that the text is mathematically and physically rather advanced and its understanding assumes supplementary study of the books listed in the list of references.

Systematika cievnatých rastlín, 5. vydanie

E-book

E-book

Pavol Mártonfi

The university textbook deals with the latest knowledge from the systematics of vascular plants in a clear manner. Vascular plants arose in the Silurian period in the Paleozoic, when the first primitive plants moved from water to dry land, which required evolutionary progress in the morphological and anatomical structure of these plants. During about 420 million years of the existence of vascular plants, several of their main groups have evolved: the spore vascular plants, including the lycopods (branch Lycopodiophyta) and group of ferns and related plants (branch Monilophyta), and the seed plants, including gymnosperms (branch Gymnospermae) and angiosperms ( Angiospermae), which currently dominate among plants. The textbook provides a brief but comprehensive overview of the main groups, orders and families of plants with their description, distribution, main representatives, while also addressing the useful properties of selected species. The work is complemented by an overview of the system of plants by Cronquist, Tachtadžjan, APG and an overview of the families of the Slovak flora, as well as a taxonomic index.

Stresová fyziológia rastlín - Návody na cvičenia

E-book

E-book

Jozef Kováčik

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.

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.
