Information System Proposal for Automation of Selected Processes
Mruškovičová, Timea ; Oravec, Matej (referee) ; Luhan, Jan (advisor)
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 (advisor) ; Cibulková, Petra (referee)
This thesis examines the interests of the Member States of the Shanghai Cooperation Organisation with a narrow focus on the interests of the four Central Asian members of the organization. The first two chapters are devoted to theoretical approaches to international relations and the concept of state interest. The work considers liberal-idealistic tradition as the most suitable theoretical approach for applying. There is no single, universally accepted definition of state interest, therefore the assessment of national interest is always subjective in nature. The state interests are then compared in the three chapters focusing on political view, security and economic cooperation. The security cooperation within the international organization is the only area of cooperation with tangible results. Economic cooperation among the countries as members of the Shanghai Cooperation Organization is indeed verbally declared, however, the real results are not visible. The work concludes that the common interests of the four Central Asian states are in the area of security and economic cooperation, cooperation in transport infrastructure development, as well as solving energy issues and issues related to water resources. Specific interests of the monitored countries are determined by their geographical location...
Combined effect of temperature and CdO nanoparticles treatment on Picea abies
Večeřová, Kristýna ; Mikuška, Pavel ; Oravec, Michal ; Kozáčiková, Michaela ; Pompeiano, Antonio ; Coufalík, Pavel ; Urban, Otmar
Three-years old seedlings of Picea abies were pre-treated under two different\ntemperatures (20x35 °C) and subsequently exposed to elevated concentration of CdO\nnanoparticles (CdONPs). Two-week exposure to airborne CdONPs of ecologically\nrelevant size and concentration significantly reduced photosynthetic light use efficiency\nin plants as well as contents of photosynthetic pigments and saccharides. In contrary,\namino acid content was increased under CdONPs. These changes were further\nmodulated by previous growth temperature.

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

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.
Metabolomic approach to the study of nanoparticles impact to barley plants
Večeřa, Zbyněk ; Večeřová, Kristýna ; Oravec, Michal ; Kozáčiková, Michaela ; Urban, Otmar ; Tříska, Jan
Barley plants in the pots after formation of second leaves were exposed in the special chamber to elevated concentration of CdO nanoparticles. After three weeks exposure the content of primary metabolites was measured using metabolomic approach and compared with the control.

The content of microcystin in the chosen tissues at different fish species
Hlávková, J. ; Adamovský, Ondřej ; Oravec, M. ; Bláha, Luděk ; Mareš, J. ; Kopp, Radovan ; Palíková, M.
The aim of this study was to assess quantity of microcystins in muscle and hepatopancreas of different fish species (Cyprinus carpio, Oreochromis niloticus, Sander lucioperca and Esox lucius). Microcystins were detected in liver/hepatopancreas (hundreds of ng per gram of tissue) as in muscles (nanograms per gram of tissue). It seems that acumulation of microcystins in eatable parts of fishes represent only small risk for man.
