Zborník abstraktov príspevkov účastníkov Študentskej vedeckej konferencie PF UPJŠ v Košiciach, ktorá sa konala 26. apríla 2017.

Už po piaty raz vychádza zborník zo Študentskej vedeckej konferencie (ŠVK) na Prírodovedeckej fakulte Univerzity Pavla Jozefa Šafárika v Košiciach. Teší nás, že ŠVK je pevnou súčasťou života fakulty a výkladnou skriňou kvality poskytovaného vzdelávania. V roku 2017 sa ŠVK konala v rámci tradičných Prírodovedeckých dní dňa 26. apríla 2017. Vystúpilo na nej 105 študentov Prírodovedeckej fakulty. Príspevky boli zaradené do 15 sekcií, ktoré navyše dopĺňala otvorená súťaž v programovaní, do ktorej sa zapojilo 17 študentov a finále súťaže IHRA, v ktorej súťažilo 27 tímov z celého Slovenska.

Abstrakty príspevkov prezentované v tomto zborníku dokumentujú, že na PF UPJŠ získavajú študenti poznatky a vedomosti zo svojho odboru nielen teoretickým štúdiom jednotlivých disciplín, ale aj aktívnym zapojením sa do riešenia čiastkových vedeckých problémov, ktoré sú súčasťou výskumných zámerov na ústavoch PF UPJŠ. Abstrakty príspevkov predstavujú svojim spôsobom aj prehľad o vedeckej aktivite na fakulte, ktorý, veríme, bude zaujímavý aj pre širšiu verejnosť.

This electronic material provides the basic principles of creating a systematic nomenclature of organic compounds, from the simplest hydrocarbons to the more complicated nomenclature of carbohydrates. For some groups of derivatives, alternative ways of generating system names are also mentioned, as well as the most common trivial names that are still in use in the literature and in practice, in some cases being the characteristic (dominant) ones. In the introductory section, the basic rules to be respected when writing names of organic compounds are discussed. This document is intended primarily for interdisciplinary undergraduate and graduate students as support material for the courses Organic Chemistry and Selected Chapters in Organic Chemistry and Biochemistry. In the final section of this document, solved examples are given so that the student can check how the rules for forming the names of organic compounds have been understood.

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.

Neuroscience is an interdisciplinary field of science at the interface of biological, psychological and computer sciences, which aims to describe the functioning of the brain and mind. Computational and cognitive neuroscience are subfields of neuroscience focused on the study of information processing in the human and animal nervous systems, and on the theoretical description of the brain and mind. This university textbook contains several assignments that provide an overview of the methods used in computational and cognitive neuroscience, with an emphasis on mathematical modeling and on the behavioral study of cognitive processes. The textbook builds on the author's previous works.

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.

Photonics is an application-oriented discipline at the interface of optics, opto-electronics and quantum optics. It includes classical optics extended by the description of physical phenomena and optical devices that rely on quantum (photon) nature of light.
The main objective of the Photonics course is to provide a comprehensive overview of essential optical and photonic phenomena routinely applied in experimental scientific research while working with various light sources (e.g. in the field of biophotonics). The first chapters are devoted to the description of light at different levels. The logical order of subsections in this part corresponds to the structure of the textbook: B. E. A. Saleh, M. C. Teich, Fundamentals of Photonics. The following chapters contain a description of laser operation and an overview of selected optical instruments and their applications.
The body text is complemented by practical notes on the use of theoretical knowledge during daily work in the laboratory. The course of Photonics requires a basic knowledge of mathematics, electromagnetism and optics, and thus it is recommended to students who previously passed through the courses of the Bachelor's program in Physics.

An important part of theoretical computer science is the problem of Turing machines. This computational model has two basic properties: like any other computational program, the software of a Turing machine is composed of instructions, but in its case they are all of a single type. Every other (so far known) computer program can be transformed into a Turing machine program without loss of information. While the second feature reduces the question of what a calculator cannot do to the question of what a Turing machine cannot do, the first feature allows a much simpler investigation of such a question. Using this computational model, we can thus find concrete problems that no automaton can ever deal with (perhaps the most famous is the problem of the Turing machine stopping). Their existence demonstrates the fundamental limitations of (not only ideal) computational means, and thus encourages both criticality and humility in our thinking.
