Environmental taxes in OECD countries
Franková, Martina ; Láchová, Lenka (advisor) ; Kouba, Tomáš (referee)
The object of the diploma thesis is to analyse the environmental taxation in the OECD countries, to inform the readers about the development of environmental taxes and current trends in tax revenues from environmental taxes. The thesis is also focused on the structure of revenues from environmental taxes, the significant part is created by energy taxes, especially by taxes on motor fuels. Attention is also paid to taxation of carbon dioxide, according to the OECD the carbon taxes are one of the effective tools to reduce CO2 emissions, which is important to achieve the targets set under the Kyoto Protocol. The explicit carbon taxes are applied in the 12 tax systems of 12 OECD member countries and in the Canadian province of British Columbia. An increase of the countries applying carbon taxes since 2010 demonstrates the increased demand for this tool in recent years. The object of the last part of the thesis is to analyse whether declining tax burden on labour while increasing tax burden on energy is put into practice.

Vliv zvýšené vzdušné koncentrace oxidu uhličitého na růst buku lesního
Sokolová, Tereza
Elevated CO2 concentration influences the anatomical, physiological and morphological characteristics of plants, both directly and indirectly. The aim of this thesis was to determine the effect of increased atmospheric CO2 concentration on growth of European beech (Fagus sylvatica). The experiment was carried out from autumn 2005 on environmental work place Bílý Křiž in Beskydy and established in artificial conditions (A-ambient - natural air concentration of CO2 - 385 ppm, E-elevated - 700 ppm, C-control - open control area). Two-year old seedlings of beech and three years old spruces seedlings have been planted in a triangular spacing in lamellar biospheres in a total of 96 individuals. The study is focused on biomass production of beech in different types of mixed cultures together with Norway spruce (P-pure - monoculture, I-Individual -- individual mixing, G-group -- group mixing). In mid August 2013 has begun destruction of beeches, which was completed in September 2013. Aboveground parts were dividend in to group consisting of branches and trunk and roots were subjected to destructive analysis later. Separate parts of the trees were dried in the oven for 48 hours at 80 °C and subsequently 2 hours at 105 °C and then were weighed to determine the biomass. After eight years of experiment, cultivation of spruce and beech in lamellar biospheres, there were no signifiant differences in total biomass of trees between varieties A and E. However, it showed significant influence of CO2 on the biomass of individual organs (leaves, branches, trunks and roots, including stumps ) as well as trees grown in a single mixed culture (I). When comparing the total biomass in the spheres, sphere E showed average total biomass of an individual tree about 27 % higher, in mixed G variety 25 % lower and in the P mixing 147 % higher than mixed I in the sphere A. Biomass production of roots without identification of mixing factor increased by 60 % in the E variety. Most significant difference in belowground biomass was detected in variety of mixing I. In the E sphere was 200 % more belowground biomass compared to sphere A. These preliminary results show that total biomass of beech was higher in sphere E than in the sphere A. Differences in total biomass , however, can be caused by mixing and correspond to the concentration of CO2.

Způsoby a metody zpomalování zralosti jablek
Majorová, Anežka
Three cultivars of apple (Idared, Prima, Golida) were harvested in three stages of ri-peness (unripe, ripe, overripe) that were stored for 30 days in two different temperatures (2 °C a 20 °C). On all cultivars, the ripeness was studied during the storing based on objective measurements. The performed measurements enabled to determine 3 basic criteria (penetration stress, soluble solids, acid-based titration). From the stored cultivars, Prima was ripe in the time of measurement, cultivars Idared and Golida reached similar in descibed parameters that are stated by the average and standard deviation. The aim of this work was to find optimal ripeness of apples, especially for long-term storage. Knowing of materiál composition during the harvest was important for studying of ripeness. The changes and values are observed and recorded. According to these values, the conditions for every cultivar for long-term storage and maintenance of apples at optimum ripeness are determined.

Contribution capnometrics in pre-hospital emergency care
BENEDIKT, Ladislav
In terms of prehospital emergency care (PEC), the rescuers get into contact with patients, who have breathing difficulties in connection with their health condition. As breathing, together with consciousness and bloodstream, is included in the observed vital signs, it is necessary to focus on the precise monitoring of its quality. Except evaluation by sight, we can also beneficially use device monitoring of breathing, more precisely the quality of blood gases exchange. During PEC we can monitor oxygen or carbon dioxide saturation in blood (pulse oximetry or capnometry, respectively). In this bachelor thesis we focused on capnometry. The principle of capnometry measurement is based on infrared light absorption. In comparison with pulse oximetry, the capnometry is useful in situations when we are not able to get objective results by using pulse oximetry. The greatest advantage of capnometry is the almost immediate reaction of a device to metabolic changes in respiratory system of a patient. Using this method is also beneficially during intubation, using combitube and laryngeal mask, because we can get precise overview about cannula position. Theoretical part of this bachelor thesis is focused on capnometry problematics. At the beginning is explained what capnometry and PEC are and they both are described. Also view on monitoring in general is present. The capnometry itself is divided into types according to way of use. Theoretical part is ended by chapter about capnography. The aims of practical part are monitoring of South Bohemian rescuers' knowledge about using of capnometry and using of capnometry during PEC. Data collection were realised quantitatively by using questionnaire focused on theoretical knowledge. Data were collected in March 2015. 100 pieces of anonymous questionnaires were given for filling across the South Bohemian Region (regional centre in České Budějovice and local centres in Český Krumlov, Písek, Prachatice, Strakonice and Tábor). 63 respondents answered the questionnaire (rate of return was 63 %). Questionnaire consisted of 24 questions targeted on knowledge of respondents about capnometry problematics. Results were analysed in statistical software SPSS into graphs and charts and hypotheses were statistically analysed by using of chi-square test method. Statistical analysis shows to us that South Bohemian rescuers have enough information about capnometry and that capnometry is not used for every patient with controlled air passages. The aim of this bachelor thesis is to get information about South Bohemian rescuers' knowledge about using of capnometry. Another aim is to monitor the using of capnometry in prehospital emergency care. Statistical analysis proves that knowledge about capnometry is sufficient among South Bohemian rescuers and they are able to use this method. Furthermore the guide for using of capnometr for rescuers was created on the basis of obtained information. This guide is included in this thesis as an appendix (app. 11).

Environmental aspects of energy crops growing - production of CO2eq
PÍSAŘÍK, Martin
This thesis deals with the partial evaluation of the life cycle of three kinds of power plants, particularly flint corn ( Zea mays L.) , reed canary grass ( Phalaris arundinacea L.) , Szarvazi I ( Agropyron elongatum L.) and their environmental impact during their cultivation. As an evaluation framework was used seedbed preparation time from the first year to the last harvest after ten years growing cycle. To calculate the emissions of greenhouse gases has been used software tool SimaPro . The aim was to find out how much greenhouse gas emissions (kg CO2eq per 1 kg of dry matter ) is created in the cultivation of selected power plants and compare that plant is from an environmental point of view the most environmentally friendly. The total emission load produced during the life cycle of corn is sown CO2eqv 0.199210 kg per 1 kg of dry matter , with reed rákosovité CO2eqv 0.182075 kg per 1 kg of dry matter. I Szarvasi is from an environmental point of view the most friendly CO2eqv produces 0.110232 kg per 1 kg of dry matter.
