Chržová, Anna ; Bažant, Václav (advisor) ; Vítámvás, Jan (referee)
Abstract
This thesis deals with the evaluation of the annual radial increment measured during the vegetation period 2014 and 2015 on three species of trees in the Arboretum of The Faculty of Forestry and Wood Sciences of the Czech University of Life Sciences Prague in Kostelec. Evaluation of the seasonal dynamics of radial increment of Abies grandis (Grand fir), Picea sitchensis (Sitka spruce) and Pseudotsuga menziesii (Douglas fir) on plot stands in the Arboretum in Kostelec was made by comparing the climate in the time period and the annual radial increment as it changed during the season. Annual radial increment of Abies grandis, Picea sitchensis and Pseudotsuga menziesii was detected by device EMS DRL26A. This device also subscribed information about the temperature during the growing season. Data was processed by software EMS Mini32 and exported to Microsoft Excel 2016. Information about the temperature, I determinated with using a meteorological station in the area of the Arboretum. Data fromdendrometer and weather station and their interdependence was evaluated using Microsoft Excel 2016 in the form of line charts. In 2014, I was dealing also phenological phases and the time of onset and end of it on observed species. Due to the extremely warm and dry year 2015, I had the opportunity to compare the responses of individual species at these climatic phenomens. In conclusion, the results are confronted with the literature searches and the discussion in this thesis, where I focused on the characteristics of measured trees and their application in European conditions

Human behaviour in crisis situation
Radová, Markéta ; Kebza, Vladimír (advisor) ; Daniel, Daniel (referee)
This dissertation thesis is based on behavior of human in crisis situations, and the focus is on stressful situations that police officers are involved in. The thesis defines basic concepts issues, analysis not just of the stressful situations, but also reaction to them, furthermore characteristics of the studied group and it lays out some of the general recommended stress management techniques.
Performance of the municipal police in the Czech Republic are so specific, that the foreign principles were mentioned only marginally, and only because of the complex transnational perspective.
The practical part of the final paper is focussed on identifying the most stressful situations that threaten officers and policemen in their work. This empirical research was conducted at pre-selected locations, so that they can compared with the capital city Prague to the results of smaller towns, villages at several locations in the Czech Republic.
In addition, techniques were examined for coping with stress for the municipal police, and from the perspective of the individual police officer.
In conclusion, there are specific recommendations to the data found in the survey.

Factors affecting the nitrogen compounds removal process in specific types of wastewater
Radechovský, Josef ; Balík, Jiří (advisor)
Abstract:
This work summarizes the current knowledge about removing of nitrogen compounds from wastewater using non-traditional biological methods. They include for example process of nitritation/denitritation and a process of deammonification. Special innovative biological methods are economically advantageous because of savings of oxygen for the oxidation of N-ammon and organic substrate for the formation of N2.
Achieving of accumulation of nitrites (achieving of shortcut nitrification) due to suppression of nitrite oxidising bacteria (NOB) is the basis of methods mentioned above. Stable shortcut nitrification is influenced by many factors and achieving of this process in a low-strength wastewater is still problematic, so some new procedures how to optimize it are investigated. This was also the main aim of research that was realized at the Department of Agroenvironmental Chemistry and Plant Nutrition of the Czech university of Life Sciences in Prague.

ICT support for regional development
Očenášek, Vladimír ; Havlíček, Zdeněk (advisor) ; Vostrovský, Václav (referee)
There are many of different rankings in the world, which relate to information and communications technology. For example, United Nations e-Government survey evaluates expansion of e-government administration in 193 countries in the world every two years and publishes worldwide ranking of EGDI (e-government development index). Since 2003 web portals of the capitals of the largest countries in the world are evaluated evaluated by - Digital Governance in Municipalities Worldwide (Holzer et al., 2014) every two years. This rating is organized by the "The E-Governance Institute" which is part of Rutgers University Newark. Prague (15 in) was included for the first time in 2007. Prague was ranked in excellent 2nd place in 2009, in the period 2011 - 2012 was in 4th place and in the period 2013 - 2014, Prague ranked 10th. Our methods of evaluation are based on methods of Digital Governance in Municipalities Worldwide, which is focused on regional web portals. We evaluated 6 regional web portals using 40 parameters in the area privacy, usability, content, services, citizen and social engagement. For instance, we evaluated if web portal provides: online publications, multilingual access, GIS, calendar of events, searchable database of articles, accommodation reservation etc. For evaluation of regional web portals, we chose two regional touristic headquarters (Centrála cestovního ruchu -- Jižní Morava (www.ccrjm.cz), Jihočeská centrála cestovního ruchu www.jccr.cz)), one regional touristic web (Posázaví - vítejte v turistickém regionu kolem řeky Sázavy (www.posazavi.com)), two Austrian web portals, which represents cross-border cooperation between Austria and Czech republic (Urlaub am Bauerhof -- dovolená na selském statku (www.agroturistika-v-rakousku.cz), Rakousko -- přijeďte a ožijete (www.austria.info/cz)) and official touristic web portal of Switzerland (Officielle Website von Schweiz Tourismus (www.mojesvycarsko.com)). As it turned out during our model usage, which took into account five important areas, level of regional web portals significantly differ. Some criteria are fulfilled across the all sites, but some of them are partly or completely missing. Individual solutions therefore often prefer different criteria, thus providing different perspectives on the region and its issues. If all criteria were met, the informational content and thus even usefulness of the individual portals would rise. Theoretically, this would lead to a "content compatibility" of individual solutions, which would ultimately bring profit to users and consequently the visitors of their respective regions.

Changes of proline concentration and electrolyte leakage in the selected species of the Panicoideae tribe under water deficit.
Nováková, Hana ; Hnilička, František (advisor) ; Václav, Václav (referee)
The theme of this thesis is the impact of water deficit on the concentration of proline and electrolyte leakage from representatives of the Panicoideae tribe. The impact of drought on agricultural production in the environment of the Czech Republic is currently an important issue. The exceptionall dry year of 2014/2015 and the associated water deficit in the soil had an impact mainly on the harvest of wide-row crops, including maize. Representatives of the Panicoideae tribe - sorghum and foxtail millet are the most drought-resistance crops in the world. Sorghum and foxtail millet belong to II. group of cereals like maize. Sorghum and foxtail millet show lower transpiration coefficient than maize, they also tolerates less demanding growing conditions and are more resistant to diseases and pests. They also compete with maize in a wide range of applications. It is therefore appropriate to determine how these crops respond to water deficit during their ontogenetic development. For the purposes of this experiment genotypes originating from conditions of temperate climate were selected, this genotypes have a shorter growing season. A short growing season is an important factor in the timing of the harvest of the late sown crops in our climate.
The aim of the thesis was to determine and evaluate the impact of water deficit on the concentration of proline and electrolyte leakage in selected genotypes of sorghum and foxtail millet and on the basis of the results to select genotypes with high resistance to water deficit. Based on the aims the following hypotheses were set: to determine whether there are differences in the concentration of proline and electrolyte leakage between selected genotypes depending on the effect of water deficit and whether there are differences in these physiological characteristics in response to water deficit between sorghum and foxtail millet. To fulfill the objectives and evaluation the hypothesis was based on the greenhouse experiment with selected genotypes of sorghum and foxtail millet at the Department of Botany and Plant Physiology in the Czech University of Life Sciences Prague.
The experiment included 4 genotypes of the species Sorghum bicolor (L.) Moench. (Sorghum): 1216, 30485, Barnard Red and Ruzrok and one variety of the species Setaria italica (L.) Beauv. (Foxtail millet) Ruberit. A total of 4 variants were designated for the experiment (one control and three under the influence of water deficit in different times). The plants in the control variant were full irrigated throughout the experiment. Variant KS was irrigated for the first 14 days, followed by 10 days without watering and the last 4 days were again irrigated. Plants in variant SK were under the influence of water deficit for the first 10 days of the experiment, then 18 days with watering and the plants in the variant SS were without watering for the first 10 days, for the next 4 days were without watering, then the same pattern was repeated: 10 days without and 4 days with watering. Physiological characteristics were observed in plants in the developmental stages BBCH 14-16. The concentration of proline was determined by measuring the absorbance of the samples formed by the reaction with ninhydrin. Subsequently, the measured values were compared with the calibration curve. To measure the sample absorbance at 520 nm a spectrophotometer Hellios gama (Thermo) was used. Electrolyte leakage on discs made from leafs was measured with electrical conductivity meter GRYF 158 (HB Griffin, Ltd.).
The obtained results show that the proline concentration increased in response to water stress, since the highest concentration of proline was detected in plants growing in the most stressed variant of SS (670.13 micrograms) compared with other variants of stress. Plants variant KS (643.85 micrograms) showed a higher accumulation than the proline in variant SK (636.69 micrograms). The highest concentration of proline was measured on a genotype in the variety of sorghum Ruzrok (642.94 micrograms). The lowest content of proline was found in the variety of sorghum 1216 (623.78 micrograms), this value was also the only significant difference from the contents of proline to other genotypes. Which at least partly confirms the proposed hypothesis that there are differences in the content of proline between genotypes.
The highest electrolyte leakage cell damage was respectively exhibited in plants from the variant SS (39.56%). Plants of the SK variant showed a higher rate of cell damage (32.95%) than plants from the variant KS (29.88%). The lowest cell damage was exhibited in plants grown under control conditions, which again indicates that damage cells increases in response to water deficit. In this experiment the highest degree of cell damage was found in the variety of sorghum 1216 (29.26%) and lowest cell damage was observed in the variety of sorghum Ruzrok (27.03%). A significant different degree of cell damage appeared only in the variety foxtail millet Ruberit (28.6%), which confirms our hypothesis that there are differences in the electrolyte leakage between sorghum and foxtail millet.
The hypotheses were not fully confirmed by the experiment. Nevertheless, on the basis of obtained results we conclude that the least drought-resistance genotype is the 1216 variety and the best adapted to the water deficit was the Ruzrok variety. It also confirmed that the higher proline accumulation may protect the plant against the negative effects of water deficit on the cell membranes, which is then reflected in a reduced electrolyte leakage.
