Doležal, Jiří ; Valášek, Rudolf (referee) ; Bělík, Milan (advisor)
The topic of the Bachelor thesis is “Analysis of activities of components of the integrated rescue system at investigation of complicated traffic accidents”. The introductory part deals with an analysis of increasing traffic operation in general. It includes detailed reviews of increasing traffic flows, analyses of accident rates for the last decade, comparison of accident rates with foreign countries for the last decade according to the data obtained from traffic statistics. The Dissertation deals also with the issues of motorway traffic and possibilities of dangers arising for drivers in this context. Examples of mass traffic accidents on motorways are provided for as well. This part is followed up by an analysis of the structure of the integrated rescue system from such points of view as its tasks towards the government, individual components and their activities. The Dissertation analyses a model example of a complex traffic accident. The intervention is evaluated and specific positive and negative aspects are emphasised. A quality improvement for the intervention carried out is mentioned in the conclusion.

External conditions, seed characteristics and other factors affecting seed germination of alpine species
Veselá, Andrea ; Münzbergová, Zuzana (advisor) ; Jiménez-Alfaro, Borja (referee) ; Doležal, Jiří (referee)
Germination is the most critical and vulnerable stage in the life cycle of many plants and it directly influences the regeneration potential of populations and thus long-term survival of species. Species germination is affected by external conditions such as light, temperature and moisture acting both during germination (target conditions) and on maternal plants during their life (original conditions). Target and original conditions can interact and affect seed germination as well. The strong temperature and moisture control of seed germination suggests that species recruitment rates and success may be strongly impacted by ongoing climatic changes. Simultaneously, species germination is influenced by characteristics of the seeds themselves, such as, seed mass or seed nutrient content, which can be affected by external climatic conditions as well. This thesis aimed to i) investigate the effect of temperature and moisture acting separately and in interaction as target conditions, original conditions and as interaction between target and original conditions on germination behaviour of alpine species; ii) study effect of seed origin on seed mass and seed nutrient content and their effect on germination; iii) explore how abundance of species is affected by germination behaviour in central European...

Anatomical and physiological adaptations of high mountain plants in Ladakh
Binter, Jan ; Doležal, Jiří (advisor) ; Sklenář, Petr (referee)
The Ladakh region of the northwestern Indian Himalaya is a high-elevation desert that presents a suite of environmental conditions that constrain plant growth. At lower elevations, aridity and high temperatures constrain plant growth. However, at higher elevations, temperature steeply drops and an increase in precipitation occurs. Therefore, the Ladakh region can be considered a natural laboratory where the adaptive responses of plant traits to moisture and temperature gradients can be observed. Plants in high mountain regions had to evolve and adapt to harsh environmental stress including low temperatures, UV radiation, short growing seasons, etc. Morphological, anatomical and physiological adaptations allow plants in Ladakh to grow at altitudes up to 6150 meters. This limit for plant growth in Ladakh is not set by the permanent snow line or any other mechanical barrier, but instead by the inability of plants to survive at such an elevation. This situation allows us to study the physiological limits of plant adaptations in extreme conditions. Thus, studying plants in Ladakh can bring an important understanding to adaptive ability of mountain plants.

Spectroscopy of single molecules in STM nanocavity
Doležal, Jiří ; Švec, Martin (advisor) ; Frank, Otakar (referee) ; Roslawska, Anna (referee)
Scanning tunneling microscopy-induced luminescence (STML) combined with high- resolution atomic force microscopy (AFM) is a powerful tool for studying the photophysics of individual molecular emitters on surfaces. However, the mechanism of energy conver- sion between tunneling electrons and photons in decoupled systems placed in a nanocavity of STM is not fully understood as it depends on many variables. This thesis presents a range of proof-of-concept experimental approaches. The vi- ability of CO-terminated tips for STML is demonstrated by performing subnanometer- resolved spectroscopy and mapping of photon intensity acquired over zinc phthalocyanine on NaCl/metal substrate. For the same molecule, time-resolved phase fluorometry is de- vised and is used to reveal the exciton and charge dynamics as a function of the applied bias voltage. Of more fundamental character, the role of the chromophore environment on its exciton emission and binding energy is studied. For the first time, we observed and explained the presence of molecular librations in molecules on the surface from a comb-like emission line resulting from the exciton-libron coupling and the chiral adsorp- tion geometry. Finally, exciton delocalization in molecular aggregates is mapped using the tip nanocavity capable of detecting the dark states,...

Evaluation of yield parameters and first pod height in soya bean (\kur{Glycine max} L.)
DOLEŽAL, Jiří
This work deals with the influence of the growth regulator on soybean vegetation. The main part of the diploma thesis is the evaluation of individual parameters of selected varieties. For this purpose, a pilot experiment was established in 2019 in the Benešov region in location Netvořice. This area is located in a moderately warm climate area in the area of potato production at an altitude of 390 meters above sea level. Two very early soybean varieties, Amandine and Abelina, were selected for this experiment, which are suitable for these conditions due to their shorter growing season. These varieties were grown in two variants. Control variant without treatment and variant with treatment with Energen Apikál, which increases apical dominance. Each variant and treatment variant was repeated 4 times to obtain the most accurate data. The following parameters were evaluated for both varieties: seed yield, nitrogenous substances content, number of plants per square meter, fat content, weight of a thousand seeds, plant height, number of primary branches, number of pods per plant, number of seeds in the pod and height of first pod. The highest average yield was achieved by the Amandine variety in the treated variant 3.49 t/ha. The Abelina variety achieved a very satisfactory yield of 3.18 t/ha also in the treated variant. In the untreated variant, these varieties also achieved a satisfactory yield. Amandine variety 2.99 t/ha and Abelina variety 3.06 t/ha. Another parameter determined was the nitrogenous substances content. This indicator also showed an increase in nitrogenous substances in the seed in the treated variant in both varieties. A very important monitored parameter was the height of the first pod from the soil surface. Here, after the application of Apikál, the lower floor of the pods increased by approximately a centimeter compared to the control in both varieties (Amandine 10.68 cm and Abelina 11.88 cm). In conclusion, Energen Apikál has a positive effect on both qualitative parameters and the main yield elements, which favorably affects the yield and, together with the higher location of plant pods, also partially minimizes harvest losses.

Functional diversity in ecological communities
Džamba, Roman ; Hořák, David (advisor) ; Doležal, Jiří (referee)
Functional diversity is an important component of biodiversity. Value and range of functional traits and the number and composition of functional types are crucial for the short and long term functioning of ecosystems. Functional traits of species affect their performance in ecosystems and we can classify them as continuous or discontinuous. It has been suggested many ways to choose the appropriate traits and functional differences between species in estimating functional diversity. It is necessary to consider the nature and importance of ecosystem processes and environmental factors and consider properties of employed methodological approaches. There are many ways to estimate functional diversity. Functional diversity can be expressed by the number of functional groups, functional index or functional dendrograms. In natural communities, we see a positive relationship between species and functional diversity. Species diversity doesn't seem to be an adequate surrogate for functional diversity because the loss of an equal number of species may have different effects on the ecosystem, depending on the identity of the species. Functional redundancy refers to the functional similarity in the ecological niches occupation and is a source of stability in the ecosystem functioning.

Community property of spouses
Doležal, Jiří ; Salač, Josef (advisor) ; Dvořák, Jan (referee)
The topic of my paper is a legal arrangement regarding communal estate in the Czech Republic. This legal institute comes into power as a result of contracting marriage, which is done by the majority of people at some point in their lives. Marriage is a long- lasting union of a man and a woman and the communal estate, then, solves the legal and estate arrangements between the spouses and between the married couple and third persons. There have been different arrangements of such concerns throughout the historical and legal development, each of which depended on social and economical conditions of the time. Nowadays, the situation is certainly not perfect, but it can be said that it is very extensive and it is believed to become even more extensive and superior due to the new Civil Code, which is supposed to be accepted soon. At the present time, the arrangements of communal estate are to be found in the law no. 40/1964 of the Civil Code. In particular, it is a part of the second Head of the law, named Joint ownership and Communal estate, under the term Communal estate. My paper could be divided into three separate parts. In the first one (Chapter II), I describe the historical development of the institute with special regard to the development of the legal arrangement from the time of the Roman Law,...
