The potential of deep seabed polymetallic nodules
Tormová, Lucia ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
The deep seabed polymetallic nodules are one the major types of deep-sea ore resources. Oceanic deposits of these raw materials represent a potential source of numerous metals that are in short supply on the land-base deposits at the nearest future. The process of geological survey to the deep ocean floor is considered to be an onset of a quantitatively new stage in the process of mineral resource extraction. Continuation of the on-going work on polymetallic nodule deposits within the Clarion-Clipperton Zone is regarded as a serious task to be undertaken over a period until the year 2025, with a due consideration to advance in designing of an efficient mining unit and application of modern processing technologies for extraction of major metals : manganese, nickel, cobalt and copper. A prerequisite of a rational management of oceanic resources is the preservation of natural oceanic environment. Considered is the extraction's profitability of a concrete deposit within the Clarion-Clipperton Zone, which is the exploration area of the IOM, with annual production scale of 2.2 Mt of wet nodules for the year 2025.

Analysis of the vehicles on compressed natural gas purchased by RWE CZ Group
Bartejsová, Vladimíra ; Hadrabová, Alena (advisor) ; Dvořák, Antonín (referee)
This paper analyses the purchase and operation of vehicles on compressed natural gas. It contains a definition of Compressed Natural Gas (CNG) and discusses the various phases of its use in transport. It indicates the differences of this alternative fuel compared to traditional fuel such as gasoline or diesel. Then it focuses on the main reasons to support the use of compressed natural gas transport and talks about the legislation which has a major role in the development of alternative fuels. Then it specifies the disadvantages which can be associated with its use in transport. The last section includes an analysis on the specific example of the RWE CZ Group, which compares the different costs for compressed natural gas vehicles and vehicles which run on conventional fuel. Specifically the cost per kilometer of vehicle, CO2 emission and purchase price are given for comparison.
Construction efficiency of low-energy residential buildings
Zgúthová, Katarína ; Šauer, Petr (advisor) ; Dvořák, Antonín (referee)
Construction of low-energy residential buildings (i.e. houses with low energy demand) in the Czech Republic is not as common as in other countries in the region. This thesis examines the reasons for such development and whether or which obstacles potential buyers face. The analysis of the economic choice between "regular" house and a low-energy building will be primarily based on comparison of basic parameters of both types of constructions. Data for this research will be taken from commercial developers. Quality analysis in the form of detailed interviews with developers, architects and potential buyers will follow. The last section of this thesis will deal with the approach of Czech media towards low-energy development. Presentation of this issue to the public will be examined by the frequency and content of reports.
Analysis of environmental subsidy and its environmental impact
Alferiová, Diana ; Hadrabová, Alena (advisor) ; Dvořák, Antonín (referee)
Efficiency of subsidies which aim at improving of environment quality in Czech Republic we evaluate through the use of regressive analysis and we pursue dependence between environmental protection government expenditures in Euro per capita and % of GDP in years 1996 -- 2008 and total greenhouse gas emissions of selected countries of EU in years 1998 -- 2008. The results show us that expenditures of GDP are better index for efficiency evaluation of subsidies, which confirms the importance of economic performance, though I supposed that expenditures in Euro per capita have more significant part.
Low-energy buildings as a source of energy savings
Smoleňová, Daniela ; Hadrabová, Alena (advisor) ; Dvořák, Antonín (referee)
The issue of low energy construction is currently actual and often discussed topic. The main reason is continuously increasing consumption and price of energy. Additionally, projections show this trend is not going to rapidly change in the upcoming years. The construction of buildings in low energy standard should become one of the most significant sources in energy savings in European Union for the upcoming period. Low energy constructions in contrast with standard constructions are distinguished not only because of low energy consumption and lower operating expenses but also for its favorable impact on the environment. The main purpose of this thesis will be the assessment of economical effectiveness of current low energy constructions and underline the importance of energy saving constructions by using LCA method as one of the possibilities in increasing the quality of environment.
