Information System Proposal for Automation of Selected Processes
Mruškovičová, Timea ; Oravec, Matej (oponent) ; Luhan, Jan (vedoucí práce)
The bachelor thesis deals with the issue of business processes and its automation. The starting point of the assignment is the result of the analysis of the current situation of the company VEEM Ltd. and the requirements of the company. The analysis focuses on the company’s processes, its competitors and internal resources. As a solution to the problem of non-optimal processes this thesis presents a part of the information system via an Internet interface and a special Web application. These enhancements provide competitive advantages for the company, attractiveness and transparency for the customers and the main purpose is simplification and speeding up work of the employees.

The Shanghai Cooperation Organisation - interests of the member states
Oravec, Marián ; Horák, Slavomír (vedoucí práce) ; Cibulková, Petra (oponent)
Táto práca sa zaoberá záujmami členských štátov Šanghajskej organizácie spolupráce, s užším zameraním na záujmy štyroch stredoázijských členov tejto organizácie. V prvých dvoch kapitolách sa venuje teoretickým prístupom k medzinárodným vzťahom a pojmu záujem štátu. Práca považuje za najvhodnejší teoretický prístup pre aplikáciu liberálne- idealistickú tradíciu. Neexistuje jednotná, všeobecne uznávaná definícia pojmu záujem štátu, preto posudzovanie národného záujmu má vždy subjektívny charakter. Záujmy sledovaných štátov sú následne porovnávané v troch kapitolách zameraných na politický pohľad, bezpečnostnú a ekonomickú spoluprácu. Jedinou oblasťou spolupráce, v rámci sledovanej medzinárodnej organizácie, s hmatateľnými výsledkami je bezpečnostná spolupráca. Ekonomická spolupráca medzi sledovanými štátmi ako členmi Šanghajskej organizácie spolupráce je síce verbálne deklarovaná, jej reálne výsledky však nie sú viditeľné. Práca prichádza k záveru, že spoločnými záujmami štyroch stredoázijských štátov je oblasť bezpečnostnej a ekonomickej spolupráce, spolupráca na rozvoji dopravnej infraštruktúry, ako i riešenie energetických otázok a otázok súvisiacich s vodnými zdrojmi. Špecifické záujmy sledovaných štátov sú determinované ich geografickou polohou a charakteristikou, energetickou situáciou či...

Elevated temperature stimulates light-induced processes that contribute to protecting photosystem II against oxidative stress
Materová, Z. ; Štroch, Michal ; Holubová, I. ; Sestřenková, J. ; Oravec, Michal ; Večeřová, Kristýna ; Špunda, Vladimír
We focused on elucidating the impact of elevated temperature on rapid induction of zeaxanthin (Z)- dependent photoprotection in two different plant species. The dynamics of violaxanthin (V) de-epoxidation under different illumination regimes was studied together with chlorophyll a fluorescence transients in Picea abies seedlings and Arabidopsis thaliana leaves pre-acclimated to temperatures ranging from 20 to 40°C. Whereas for spruce seedlings the rapid phase of V de-epoxidation (induced by either 10 s illumination or 10 light pulses 1 s in duration at 1 min intervals) was gradually stimulated upon increasing temperatures, for A. thaliana leaves considerable acceleration of V de-epoxidation occurred only at 40°C. Moreover, only for spruce seedlings was a considerable amount of Z accumulated after 10 × 1 s illumination. Elevated temperatures stimulated rapid formation of Z-dependent non-radiative dissipation of excitation energy within photosystem II (NRD) induced by 1 s light pulses only for spruce seedlings. The possible role of a specific fatty acid composition in spruce thylakoid membrane lipids in facilitated V de-epoxidation and NRD induction at elevated temperatures is discussed.

The relationships of soil CO2 flux with selected Norway spruce root parameters and sterol content in the soil
Holub, Filip ; Fabiánek, Tomáš ; Večeřová, Kristýna ; Moos, Martin ; Oravec, Michal ; Tříska, Jan ; Marková, I. ; Edwards, Magda ; Cudlín, Pavel
The flow of CO2 from the soil is a very important part of the carbon cycle in an ecosystem. The aim of our work was to determine how roots and rhizospheric fungi contribute to CO2 flux from the soil. Preliminary results from two years of research are presented. The research on how root biomass as well as ergosterol and phytosterol contents in roots and soil affected CO2 flux from the soil was conducted in a 108-year-old Norway spruce (Picea abies (L.) Karst.) forest in the Drahany Highlands during 2010 and 2011. CO2 flow was measured using a LI-8100 portable closed gasometric system (Li-Cor, USA). The dry weight and volume of individual root categories (< 1 mm, 1–2 mm, 2–5 mm, > 5 mm), C and N contents in the roots, as well as ergosterol, β-sitosterol, and campesterol contents in the soil and roots were determined from root-containing soil samples located in the circular measurement chamber. In addition, sterol content was determined in the soil only. Our soil respiration results correspond with the findings of Buchman (2000) who found respiration values between 5–7 μmol CO2 m−2 s−1 in a 111-year-old spruce forest. A significant influence on soil respiration was proven only for sitosterol content in the soil. The relationships among soil CO2 flux, root characteristics, and nitrogen and sterol contents in the roots and soil are discussed.

Obsah microcystinu ve vybraných tkáních u různých druhů ryb
Hlávková, J. ; Adamovský, Ondřej ; Oravec, M. ; Bláha, Luděk ; Mareš, J. ; Kopp, Radovan ; Palíková, M.
Cílem této studie bylo zhodnotit množství microcystinu ve svalech a hepatopankreatu různých druhů ryb (Cyprinus carpio, Oreochromis niloticus, Sander lucioperca and Esox lucius). Microcystiny byly detekovány zejména v játrech (stovky ng/g tkáně), ale také ve svalech (ng/g tkáně). Akumulace microcystinů v konzumovaných částech ryb představují malé zdravotní riziko pro člověka.
