Comparison of production and conditions of use of liquid biofuels in different countries
Semerák, Adam ; Pecen, Josef (advisor) ; Krepl, Vladimír (referee)
Biofuels production has experienced rapid growth in recent years. Many countries initiated legislative measures to promote their development, production and use in the transport sector. However, there are also growing concerns about the economic, environmental and social sustainability of biofuels, as well as their ability to truly meet the expectations of energy security. This paper attempted to point out the complexity and diversity of the production and use of liquid biofuels in the transport sector while using available information resources. More specifically, bioethanol and biodiesel which are most commonly used biofuels. Furthermore, he also tried to point out the diversity of characteristics and impacts in production and use of liquid biofuels, as well as the importance of consideration of the specific local conditions. That was examined from four perspectives of sustainability: technological, economical, socioinstitutional, and environmental. To illustrate the diversity and interdependence of the impacts of this whole issue two countries with very different human development indexes were selected. The Malaysia and India. At the basis of this paper the author concluded that for successful and sustainable production of liquid biofuels there must be taken into account all the factors examined equally. He also emphasized the importance of further research of this renewable energy source in terms of ensuring future energy security.

Kuperová, Zuzana ; Janeček, Vladimír (advisor) ; Vítámvás, Jan (referee)
This thesis mapped and analysed scattered vegetation in farmer landscape. The selected location was Litomerice area, especially the hill Lovos, what is an interesting place of its dendrology evolution in historical aspect. The goal of the thesis was to describe and analyse a vegetation diversity and dependency of it on the locations conditions. Also to map a trend in vegetation composition and structure. The composition of vegetation was strongly affected by post WWII era and a collectivization period. There was not described only the composition and structure of vegetation, but also a volume of the dead wood, visible stones above the land, connectivity, levels and water influence, means persistent water. It was found majority of fruit trees and isolated trees. The most successful vegetation was dog-rose (Rosa canina) and elderberry (Sambucus nigra). The mentioned vegetations are bushes and the big influence on the succession have the bird spreading and the seed resistance. The most successful trees were old world walnut (Juglans regia) and europian pear (Pyrus communis). The observation was compared with aerial photos in Marushka and aerial photos from 1953, which made sense of majority of fruit trees.

Smart Europe in Todays World
Karasová, Natalie ; Krejčová, Nikola (advisor) ; Kouřilová, Jana (referee)
With the twenty-first century bringing a completely new economic environment, the traditional way of economic growth shifted from the industrial concept towards knowledge-based economy. Skills, creativity, and knowledge as well as innovation capacity have become the significant aspects of economic activity. However, such transformation has created various problems and risks, putting regions into a position to review the management of their overall development. Against this background, the "smart model" increased in popularity in the policy area. This thesis outlines a summary of the smart concept and evaluates selected European NUTS2 regions based on the smart city approach. It discusses a focused overview of diverse definitions of the term smart city and its conceptual relatives in order to find out factors determining the performance of a successful smart area. The analysis exploits the most recent version of Eurostat and ESPON regional datasets to evaluate the smartness of selected 177 NUTS 2. Subsequently, the thesis offers a strategic division of selected NUTS 2 regions into three main categories; very smart, smart and less smart. The paper finds that the high concentration of R&D, high level of well-educated individuals, good focus on green regional economy and good global accessibility are among the main characteristics of the selected groups. The results show that out of 177 studied regions, 52 are categorized as very smart, 66 as smart regions and 59 as less smart regions. Additionally, the paper searches for the key factors determining the regional smartness. The findings explore that high level of innovation, good Internet accessibility, and high concentration of educated population together with good overall economic performance are among the most influential factors determining the regional smartness. Together the whole analysis creates a new view on the measurement of smartness in regional context.

Priming effects and its relation to accumulation of soil organic matter during succession
Galertová, Renata ; Cajthaml, Tomáš (referee) ; Frouz, Jan (advisor)
Priming effects are fast short-term changes in the turnover of soil organic matter (SOM). Depending on sources of released CO2, priming effects are classified as real (acceleration of mineralization SOM) or apparent (release of CO2 due to accelerated microbial biomass turnover). Mechanisms causing priming effects remain poorly understood. Microbial competition, nitrogen limitation, microbial diversity changes, effect of living roots are the most often mentioned among mechanisms that cause priming effect. In my thesis I have studied intensity of priming effects in soil from post mining heap that vary in age and SOM content. These soils were affected by addition of substrates with different complexity (glucose, starch and cellulose) in two levels. Addition of 0.2 ml 1.75 % glucose, starch and cellulose solution resulted in statistically significant increase in CO2 release only in one soil. Addition of 0.8 ml 1.75 % glucose, starch and cellulose solution cause significant increase in released CO2 in 3 from 5 soils. Causes of these changes are not clear however in some cases it exceed level of added C could mean real priming effects connected to release already stored C. In soils where organic matter was accumulated on the soil surface and is not mixed into soil was observed the most strong priming...

Global Environmental Agreements and Their Effectiveness
Tachecí, Petra ; Chlapcová, Ivana (advisor) ; Trávníčková, Zuzana (referee)
This diploma thesis deals with global environmental agreements and their effectiveness. Its aim is to disclose the causes of success of some agreements and, on the contrary, the motives of failure of other agreements. In the theoretical part, the specialities of the environmental problems are illustrated, followed by the introduction to the international environmental law and agreements. In the practical part, two well-known international agreements concerned with atmosphere are compared. They deal with similar problem, but they achieved very different results. The objective of step-by-step comparison of diverse aspects of both agreements is to discover what factors caused the great success of the Montreal Protocol in protecting the ozone layer and why the similarly conceived Kyoto Protocol failed in the combat against climate change. Last chapter concludes this comparison and defines key characteristics which are essential for the effectiveness of the global environmental agreements.

Large fixed price projects planning and analysis
Král, Miroslav ; Chlapek, Dušan (advisor) ; Reich, Pavel (referee)
A large number of different methods in the field of estimation of IS/IT projects have been developed in past years. Those methods should be used with regard to several factors. The choice and the application of an estimation method should take into consideration the current phase of each project and the wide variety of external factors, whose composition and intensity are very diverse and individual. The accuracy of the estimation considerably influences the success of the whole project. Therefore it is crucial to pay special attention to the mentioned phenomenon. The aim of this diploma thesis is to provide a comprehensive overview of the issue of the estimation of large projects for fixed price. The objective is particularly fulfilled by the provided overview and definitions of the chosen methods, the list of the most common mistakes and the interpretation of the results of an analysis concerning the portfolio of projects that were realised in an international company. The expected outcome of the diploma thesis is represented by the definition of the procedurally correct and comprehensive description of the creation of the price for a project with the fixed extent of work, which can be guaranteed with a reasonable rate of risk by a supplier. Another outcome of the thesis is the interpreted outputs of the analysis concerning the portfolio of projects realised by the international supplier of IS/IT products and services, which can be exploited for more effective estimations and project portfolio management.
