Influence of military disturbances on succession of arthropod communities in Brdy
Palivcová, Lucie ; Tropek, Robert (advisor) ; Knapp, Michal (referee)
The thesis aims for relationship between military-caused disturbance intensity and species richness, conservation value and composition of arthropods communities in the Brdy Mts. In the Brdy abandoned military area (MTA), a highly heterogeneous habitat mosaic developed by the long-term influence of military disturbances on two shooting areas of Jordán and Tok. The habitats range from strongly disturbed sites with sparse vegetation, through heterogeneous growths of Erica and Vaccinium in moderately disturbed sites, to sparse woodlands in the least disturbed sites. Based on the shooting areas history reconstruction, 24 study plots of 4 categories of different disturbance intensity were selected in both shooting areas together. Standardized sampling of seven groups of arthropods was performed in summer 2017 by pitfall traps, yellow pan traps, and light traps. More intensive disturbances positively influenced species richness of Aculeates and conservation value of spiders and beetles, but negatively affected species richness of moths. Simultaneously, the intensity of disturbances affected community composition of spiders, moths, beetles, Aculeates and Orthopteroids. Endangered species mostly affiliated to the more intensively disturbed plots. This results should be helpful in understanding of influence...

Motives of fire and blood in Bohuslav Reynek's Thirsts and in Pierre Jean Jouve's Les Noces
Raušerová, Andrea ; Vojvodík, Josef (advisor) ; Hrdlička, Josef (referee)
AN ABSTRACT IN ENGLISH LANGUAGE This diploma thesis regards poems of Bohuslav Reynek and Pierre Jean Jouve with a prism of fire and blood motives. The analysis is focused on their early works, i.e. on Bohuslav Reynek's Thirsts and Pierre Jean Jouve's Les Noces. The diploma thesis is divided into two parts, the theoretical and the practical ones. The theoretical part gives the view into problematics of blood and fire motives. It is encouraged with several theories, such as literary (Bachelard), psychoanalytic (Jung) and theological (Spidlik). The second chapter of theoretical part sums up already existing perception of the analysed texts, with the main focal point on the motives. This aim fulfils either Med's and Putna's interpretations of Reynek or Pic's and Kelly's interpretations of Jouve. The main part of the diploma thesis is then seen in the analysis of motives itself. The author of the diploma thesis searches for different representations of these motives, e.g. flaming tongues of fire (the symbol of the Holy Spirit), a pierced heart of Jesus Christ and Virgin Mary equally as their mixing, such as flaming heart, bloody sun etc. In the results of this diploma thesis there is summarised the analysis of these topoi - fire and blood and their different realisations in each work of the poets. Their attitude...

Remnant of forest at the transition from Late Glacial period to Holocene: dendroecological and palaeobotanical reconstruction
Moravcová, Alice ; Šamonil, Pavel (advisor) ; Rybníček, Michal (referee)
The remains from a sub-fossil pine forest burried in layers of peat deposits at the northern edge of the CHKO Křivoklátsko in the Central Bohemia is completely unique findings for the area of the Czech Republic. It offers new opportunities for palaeoenvironmental reconstruction and related climate changes during the Late Glacial and early Holocene epoch. The methods of dendrochronology and radiocarbon dating were used to date subfossil trees. The results of radiocarbon dating determined the existence of the forest in the period approximately 12,000 to 10,300 cal yr BP. The dendrochronological analyses revealed two continuous floating chronologies. The chronology RD4, which is long 200 years, originates from the Younger Dryas. The chronology RD6, 300 years long, originates from the Preboreal. The growth dynamics of the forest were reconstructed on the basis of the tree- ring analysis. Hydrological regime has been identified as a major disturbancy factor that influenced the growth of trees. This has been evident from synchronous phase depressions in the growth of synchronized tree-ring series. The high water table was the main cause of their extinction. This was in concordance with the results of macrofossils analyses. The effect of hydrological regime was largely influenced by microsite differences...

Possibilities for the use of fire extinguishing equipment for extinguishing fires
HRNČÍŘ, Miroslav
In my bachelor thesis about the Possibility of usage fixed fire extinguishing systems for extinguishing fires I was mainly interested in the topic of fixed fire extinguishing systems and their usage and also in the problematics of fixed fire extinguishing systems installed and used in the SYNTHOS Kralupy a. s., SYNTHOS PBR s. r. o. and TAMERO INVEST s. r. o. (companies) For this purpose, four fixed fire extinguishing systems were chosen based on the used fire extinguishing agent. According to these criteria were chosen water, foam, powder and gas based fixed fire extinguishing systems, which are described in the thesis with regard to their construction, operation and usage. Chosen fixed fire extinguishing systems were further evaluated regarding their capabilities for extinguishing fire. According to the conducted research current options for fixed fire extinguishing systems are used. Even though current options of usage fixed fire extinguishing systems are used it is possible to improve the usage of them by introducing technical and organizational measures. As a crucial technical measure, there is proposed a technical adjustment of the water based fixed fire extinguishing system. For improving the usage of this fixed fire extinguishing system and increasing the level of fire safety of the guarded object it is proposed to change this non-automatic fixed fire extinguishing system to automatic. Other devices are automatic and the proposed improvements do not have such underlying character as it in case of the evaluated water based fixed fire extinguishing system. In the theoretical part of the thesis there are described terms like fire, burning and conflagration (fire). There are named conditions and possibilities for the origin of fire and its spreading and is described the spreading of conflagration in time and space. Furthermore, the theoretical part of the thesis is concerned about named fixed fire extinguishing systems. There is the history of their use for fighting fire, the overview of fixed fire extinguishing systems based on the used agent and the description on the different kinds of fixed fire extinguishing systems along with the description of the possibilities of their use for fighting fire. In the theoretical part are also mentioned new technologies used in the field of fixed fire extinguishing systems. The conclusion of the thesis is focused on the problematics of operation and operational capability of fixed fire extinguishing systems.

Temperature as Source Sphere of Conceptual Metaphors
Hýsková, Tereza ; Vaňková, Irena (advisor) ; Pacovská, Jasňa (referee)
This thesis is focused on a research of the source domain of temperature and related concepts. It is based on the approaches of American and Polish Cognitive Linguistics. The first part is regarded to the relationship between the concepts of WARMTH / COLD and other basic concepts. The crucial part of the thesis deals with temperature as the source domain in conceptualization of emotions, emotional states and human behaviour. This part includes the description of general phenomenon in the process of mapping from the source domain of temperature to the target domain of emotions. The next chapters are focused on the Czech expressions related to separate emotions which are viewed as the target domains. There are marked the source domains of WARMTH, COLD, HEAT and FIRE in the thesis. These source domains are considered to have different roles and the human corporealness is assumed to be the main reason for the differences.
