Chosen natural resources: focuses of conflicts nad its economic consequences
Sytný, Patrik ; Vošta, Milan (advisor) ; Sankot, Ondřej (referee)
The bachelor´s thesis aims to three chosen natural resources, which are petroleum, natural gas and water, and conflicts based on disputes over them. The aim of the thesis was to valorize nature of the conflicts, define their main focus and draw prospective economic consequences. Professional literature that deals with this kind of issue, was used in order to find out the true nature of the conflicts. The result is an evaluation, which has proven, that the most influental conflicts are rising over disputes over petroleum. Their economic and political impacts are very perceptible and economically measurable in the way of GDP, the total product and other economic indicators. In the thesis has been also proven that the conflicts on the basis of natural gas have similiar nature and extent as it is in the case of petroleum, even thought in a smaller amount. The least important conflicts in a meaning of economic impacts are those over water, by those has been proven, that they do not poses such an impact on economic and political situation as petroleum or natural gas nowdays.

The Conclusion of a Contract under the United Nations Convention on Contracts for the International Sale of Goods in Comparison with Czech National Legislation
Krčálová, Kristýna ; Boháček, Martin (advisor) ; Levý, Jan (referee)
This Master's thesis focuses on the United Nations Convention on Contracts for the International Sale of Goods (CISG), better known as the Vienna Convention. The main purpose of this thesis is to evaluate conditions for application of this international treaty and to assess the contracting process under the CISG including the similarities and differences with the Czech national legislation. Finally, it seeks an answer to the question, which of these rules (international or national) are more advantageous for a Czech contractual party with respect to concluding a contract. The thesis is divided into five parts. The first one represents an introduction to the CISG, its origin and the Czech Republic's attitude to it. The second part identifies the conditions for application of the CISG and therefore defines a subject and an object of an international contract of sale under the CISG. Both third and fourth parts gradually introduce two phases of the contracting process (offer and acceptance) including the relevant case-law. The last chapter strives to complete the contracting process with an analysis of the exact moment, when a contract is concluded, as well as with an analysis of a potential battle of the forms and its impact on a contract conclusion.

Sorption and Stabilization of Metals/Mettalloids by Innovative Synthesized Sorbent Amochar.
Ouředníček, P. ; Trakal, L. ; Komárek, M. ; Pohořelý, Michael
Remediation of contaminated soil which is based on stabilization and immobilization of potential\nhazardous substance by sorption materials has been studied intensively nowadays. Biochar – activated organic carbon belongs to this group of stabilizing agents which can adsorb wide range of contaminants, including metals/metalloids. Surface area of the biochars is quite large in general and functional groups (e.g. COO–) can form chelates or alkaline elements on the surface, which is represented by cation exchange capacity. Altogether with the high pH values (7.00 – 10.00), biochars are quite effective sorbents and can adsorb metals/metalloids from the solution (ground water), especially in acidic soils (in the environments affected by intensive mining activities). Sorption\neffectiveness can be increased (especially for As (V) or Cr (VI) sorption) by modification of biochar by various types of secondary oxides. Innovative sorbent AMOchar (AMO + biochar) has been synthesized currently. The product was prepared by adding of biochar to the reaction solution during amorphous manganese oxide (AMO) synthesis. The AMOchar was formed mainly by Mn-oxalates which had coated surface of the pristine biochar. AMOchar composite was able to remove significantly higher amounts of various metal(loid)s from the solution despite the rather high pH of the material. Sorption effectiveness was high not only in case of Pb (II) sorption (almost 99%), and Cd(II) (51.2%), but also a very high amount of As(V), 91.4%. Additionally, both AMOchar composite was able to reduce Mn leaching. This can avoid potential post-contamination caused by the dissolution of less stable Mn-oxalates as observed in the pure AMO.

The occurrence of domestic and wild forms of the camels in the old world and their economic use
Burgerová, Michaela ; Gardiánová, Ivana (advisor) ; Jan, Jan (referee)
Genus camel (Camelus) includes two species, the Dromedary camel (Camelus dromedarius) and Bactrian camel (Camelus bactrianus). Camels have a wide range of utilization. People in Arabia countries but also in India and Egypt are using camels as a milk and meat animal, or even as a transport and companion animals and riding animals too. The aim of this thesis was to find sources about camel keeping and using and his role of farm animal in different cultures and countries. And about conditions and requirements in captivity. The first part of thesis contains information about phylogeny and origin of the camel family, taxonomy of camels, short information about the history of domestication and using of camels. There are also described the two species in terms of species biology etc. plus a brief mention of camel hybrids and camel breeds. The second part focuses on the use of camels. The preffered and most common use is in the production of milk, other dairy products from camel milk, fermentation of milk. Another use is for meat performance, meat composition, describes products. His utilization i also useful for other parts such as hair wool and mane, they come mainly from bactrian camel (Camelus bactrianus). The last is working utilization of camels, carrying baggage. Then hobby use. The thesis describes the conditions of keeping camels in captivity, keeping camels in Somalia, requirements for the supply of water and food, housing conditions in the Czech Republic, it is particularly widespread keeping camels in zoos. In Czech Republic they are small private camel breeders. For comparison they are conditions for keeping camels in captivity in Australia.

OPTION TREATMENT HYPERTENSIVE IN ČR AND THEIR INFLUENCE OVER NURSE CARE
HOLAROVÁ, Erika
The diploma paper was prepared on: Alternative treatment of hypertension in the Czech Republic and its impact on nursing care. Hypertension is one of the most common diseases of the cardiovascular system and it is the most frequent cause of morbidity and mortality in the Czech Republic. High blood pressure occurs more and more often nowadays and it is frequently underestimated by patients. Therefore, its treatment as well as its prevention is important. A nurse should be able to guide patients with hypertension along the right path and to advise them, especially in relation to preventive precautions against hypertension origination, but also a nurse should be close during the treatment of high blood pressure using other methods. Two types of interviews were carried out with nurses and patients at the cardiology department of hospital Nemocnice České Budějovice, a.s, at the cardiology department of hospital Na Homolce, a.s. and at the department of internal medicine at hospital Nemocnice Klatovy, o.p.s. In both the interviews, we first focused on the identification data of the nurses and the patients, and then questions were directed at answering our research questions specified in advance. According to the results of the data obtained from the interviews with the nurses and the patients, it was found that there was no difference in the nursing care provided to patients treated pharmacologically and patients with non-pharmacological treatment. The individual variants of hypertension treatment therefore have no impact on nursing care. Research question 1 was: Are there any differences in nursing care between pharmacological hypertension treatment and alternative hypertension treatment? Research question 2 was: Do alternative hypertension treatment methods affect nursing care? Both of these research questions have been answered by the data obtained from the interviews with the nurses as well as with the patients. Research question 3 was: Do patients view alternative hypertension treatment as part of the treatment of this disease? This question was answered by the data obtained from the interviews with the patients. Since the survey found that there are not any differences in the nursing care provided to patients with pharmacological therapy or non-pharmacological treatment, and that alternative hypertension treatment methods have no effect on nursing care, the two groups of patients should be educated properly and checked for high blood pressure. An appropriate recommendation is to organize additional research to the problems of educating patients on regimen precautions during non-pharmacological treatment of arterial hypertension.

Arctic tundra dendrochronology
Lehejček, Jiří ; Svoboda, Miroslav (advisor) ; Monika, Monika (referee)
Historically unprecedented environmental change in the Arctic ecosystems is often given into the context of its past and possible future development. In the region where instrumental meteorological observations are scarce archives need to be investigated in order to address this issues. The comprehensive synthesis one of the archives: long-live circumpolar evergreen Juniperus communis L. shrub is presented here. 20 individuals from southwest Greenland were investigated at the cell anatomy level to understand the ecology of the species and unhide its potential for environmental and climate reconstructions. The findings are as follows:
i) Stop of exponential cross-sectional conduit-lumen widening with increasing age is in contrast with conduit-lumen nature of trees. This indicates that shrubs do not need to saturate their water and nutrient demands via traits of classical hydraulic conductivity law but rather developed different mechanisms. Extreme weather conditions result in prostrate growth form. However, different weather factors probably influence shrub growth differently: While snow and wind act mechanically (a), temperature influences the form of growth physiologically (b). a) So long as the young shrub stem has high resilience to bend back to an upright position after snow melt and so long as it can withstand the wind during the vegetation season it most likely grows upright and the conduit-lumens widen. b) Temperature, resp. freeze-thaw events are responsible for the shrubs preference of safety (finite size of conduit-lumens) over hydraulic efficiency, thus not allowing for more primary growth. All of these (and other) factors are apparently working together and the transition of vertical to more horizontal growth is gradual. As a consequence, the conduit-lumen sizes may not have to be further increased (due to ecophysiological restrictions possibly also must not) because water is no longer transported against gravity.
ii) Observed age/growth trend has to be taken into consideration for further employment of the wood anatomical parameter in paleoenvironmental studies. That is, shrub cell parameters can only be used for this purposes if correctly detrended. This allows for more accurate as well as longer reconstructions because youth trend was often neglected in reconstructions based on shrub annual-rings.
iii) The south-western Greenland Ice-Sheet (GrIS) melt rates reconstruction is presented for the whole 20th century. This part of GrIS is considered as the most active. According to the presented reconstruction current GrIS melt rates are not uncommon for the last century being comparable to first decades of 20th century. This finding is particularly important contribution to the debate on Atlantic meridional overturning circulation (AMOC). Too high fresh water inputs into the Northern Atlantic from GrIS melting may slow down or even stop the AMOC which would result in more continental climate in Europe. Presented results indicate that this threshold lies higher than observed current melt rates of GrIS.
Fascinating Juniperus comunnis species has shown to be able to address many ecological as well as environmental open questions and due to its longevity and abundant distribution has a great potential to become an important player in the Arctic research.
