del Corro, Elena ; Peňa-Alvarez, M. ; Morales-García, A. ; Bouša, Milan ; Řáhová, Jaroslava ; Kavan, Ladislav ; Kalbáč, Martin ; Frank, Otakar
The research on graphene has attracted much attention since its first successful preparation in 2004. It possesses many unique properties, such as an extreme stiffness and strength, high electron mobility, ballistic transport even at room temperature, superior thermal conductivity and many others. The affection for graphene was followed swiftly by a keen interest in other two dimensional materials like transition metal dichalcogenides. As has been predicted and in part proven experimentally, the electronic properties of these materials can be modified by various means. The most common ones include covalent or non-covalent chemistry, electrochemical, gate or atomic doping, or quantum confinement. None of these methods has proven universal enough in terms of the devices' characteristics or scalability. However, another approach is known mechanical strain/stress, but experiments in that direction are scarce, in spite of their high promises.\nThe primary challenge consists in the understanding of the mechanical properties of 2D materials and in the ability to quantify the lattice deformation. Several techniques can be then used to apply strain to the specimens and thus to induce changes in their electronic structure. We will review their basic concepts and some of the examples so far documented experimentally and/or theoretically.

ELECTRON BEAM REMELTING OF PLASMA SPRAYED ALUMINA COATINGS
Matějíček, Jiří ; Veverka, J. ; Čížek, J. ; Kouřil, J.
Plasma sprayed alumina coatings find numerous applications in various fields, where they enhance the properties of the base material. Examples include thermal barriers, wear resistance, electrical insulation, and diffusion and corrosion barriers. A typical structure of plasma sprayed coatings, containing a multitude of voids and imperfectly bonded interfaces, gives them unique properties - particularly low thermal conductivity, high strain tolerance, etc. However, for certain applications such as permeation barriers or wear resistance, these voids may be detrimental.\nThis paper reports on the first experiments with remelting of plasma sprayed alumina coatings by electron beam technology, with the purpose of densifying the coatings and thereby eliminating the voids. Throughout the study, several parameters of the e-beam device were varied - beam current, traverse velocity and number of passes. The treated coatings were observed by light and electron microscopy and the thickness, structure and surface morphology of the remelted layer were determined and correlated with the process parameters. Based on the first series of experiments, the e-beam settings leading to dense and smooth remelted layer of sufficient thickness were obtained. In this layer, a change of phase composition and a marked increase in hardness were observed.\n

Comparison of paliative care by clients in hospice establishment and oncology department
KADLECOVÁ, Ivana
Comparison of palliative care for patients in a hospice and at an oncology ward This thesis was focused on the various aspects of palliative care for oncological patients. Palliative care and its principles have been defined and it seems crucial to apply these principles not only in hospices but also at hospital wards where there are patients indicated for palliative care. The objective of this thesis was to find out whether the care provided to hospice clients and to dying patients at hospital oncological wards corresponds to the methods and procedures defined for palliative care and to find out whether there are any significant differences between the nursing care provided to the dying in a hospice and the dying at an oncology hospital ward. Four survey questions were formulated and the question dealt with maintaining palliative care standards, differences in providing palliative nursing care for the dying at the individual institutions, whether the dying clients{\crq} needs are answered in a holistic and humane way, and the nurses{\crq} approach to the dying at the individual institutions. The carried out research is a qualitative one. The research part {--} data collection {--} was carried out in the form of uncontrolled interviews with selected members of nursing teams in a hospice and at an oncology ward. Observations and case reports were used in case of several patients in at the individual institutions. The research was carried out in St Stephen Hospice in Litoměřice and at the oncology ward of an undisclosed health care institution by which information was provided in exchange for absolute anonymity. The research part resulted in the finding that the palliative care provided in the hospice corresponds to the methods and procedures defined for palliative care. There are efforts at the oncology ward to provide as perfect care for their dying patients as possible but this care does not correspond to the methods and procedures defined for palliative care. There are problems in providing palliative care especially in inadequate spatial conditions, equipment, shortages, high workloads, and strictly specialized focus of the personnel and these clients need very individual care that cannot be frequently provided under everyday operating conditions at a standard ward that concentrates primarily on curative care. The results of this thesis will be provided to those who may be interested in the various aspects of palliative care.

Freezing technology of bull sperm in relation to its survivability and fertilization ability
Doležalová, Martina ; Stádník, Luděk (advisor) ; Jiří, Jiří (referee)
The aim of optimalization the insemination doses production is to provide the highest fertilization ability of spermatozoa during the demanding proces of processing fresh semen and its subsequent cryopreservation. Temperature changes causes spermatozoa damage during the cooling and freezing. Spermatozoa is exposed to cold shock and many others limiting factors, which leads to cell death and therefore to decline of fertilization ability of thawed insemination doses. For increasing spermatozoa resistance, exactly the plasma membrane resistance against cold shock was fraction of egg yolk LDL cholesterol (low density lipoprotein) at various concentrations into the comercially produced diluents added. It is believed that LDL acts possitively to plasma membrane and helps to maintain the fertilization ability of spermatozoa after thawing. Following step in the proces of insemination doses production is slow cooling of diluted semen and equilibration, when the straws are store at cooling box for 30 minutes to 240 hours. This period is necessary to penetrate of certain diluent components into the spermatazoa also maintain the balance between their intracellular and extracellular concentration. Also important is subsequent freezing temperature gradient of insemination doses. The most suitable freezing method is based on computer controlled temperature decline in freezing chamber which allows the precise control of ice crystals formation that could tear and kill the cell.
During 2012 to 2016 was repeatedly collected semen from the group of breeding bulls (n = 27, Holstein and Czech Fleckvieh breed) at AI centre. Semen which fulfill the standard entrance conditions in first step was evenly into several parts divided. For dilution the three types of comercially diluents AndroMed, Bioxcell and Triladyl with and without LDL addition were used. Into the diluents AndroMed and Bioxcell the concentration of LDL 4 %, 6 % and 8% into the dilent Triladyl 6 %, 8 % and 10 % was added. Diluted semen was filled into the glass capillares with volume 0,1 ml and temperature +4 °C. Subsequently the sample was placed to cold bath (0°C) for 10 minutes. Then the volume of capillare with physiological solution (37 °C) was mixed and for next 120 minutes was incubate. The effect of cold shock to proportion of live spermatozoa was evaluated by using Eosin and Nigrosine staining technique during heat test of spermatozoa survivability after spermatozoa heating and after 120 minutes of incubation.
The more suitable semen diluents which provide the higher spermatozoa resistance against cold shock were AndroMed and Bioxcell. Together the possitive effect of LDL addition into the diluents to lower decrease of proportion of live spermatozoa during heat test was found (P<0.05). The most suitable LDL concentration which had a favorable influence at spermatozoa resistance against cold shock was 6 % in diluent Bioxcell. Values of the proportion of live sperm were higher at the beginning of the heat test (+1.31% to + 3.2%) and after 120 minute incubation (+5.82% to +8.41%) compared to other diluents with and without addition of LDL.
In the next step the process of equilibration was optimized, is an important part of insemination doses production. The effect of the length of equilibration for subsequent fertilization ability of spermatozoa was evaluated using spermatozoa motility based of CASA and proportion of live spermatozoa after thawing and during heat survival test lasting 120 minutes (37 ° C). Suitable semen was diluted by comercially used diluent AndroMed based on soya lecithin, filled into the straws (0.25 ml), cooled and equilibrated in cooling box for 30, 120 and 240 minutes and freezed in programmable freezing box applying four types of freezing curves differing in temperature rate decline. There was used standard and by producer recommended 3. phase freezing curve, then 2. phase freezing curve, and 3. phase freezing curve with slower as well as rapid decline of temperature rate in freezing chamber, compared with standard freezing curve. The highest spermatozoa motility was found using 240 minutes of equilibration by +2.72% and +4.58% compared to other lengths of equilibration (P <0.05 to 0.01). The highest proportion of live spermatozoa was found using 120 minutes of equilibration (+6.87 % and +8.68 %). The highest average spermatozoa motility during heat test after thawing was achieved by using 2. phase freezing curve (from +2.97% to +10.37%, P <0.05), also in the proportion of live spermatozoa (from + 4.37% to +8.82%, P <0.01). When evaluating interaction between the length of equilibration and freezing curve (standard 3. phase and 2 . phase freezing curve), the highest average spermatozoa motility and proportion of live spermatozoa using 240 minutes of equilibration by both freezing curves was reached, there was no statistically significant differences. As well as, in all evaluated parts of this study the individual differences between ejaculate of bulls and within semen from one bull (P <0.05) as secondary effect were found.
To maintain good fertilization ability of semen during cryopreservation is necessary to increase the spermatozoa resistance against cold shock using addition of correct concentration of LDL into the commercially used diluents AndroMed and Bioxcell. Subsequently the fertilization ability of insemination dose is influenced by cooling, the length of equilibration and freezing. The length of equilibration 120 minutes and more as well as gentle way of freezing according to freezing curve, which ensures a gradual decrease of temperature in freezing chamber provided the higher average spermatozoa motility and proportion of live spermatozoa.

Life management - important concept in psychology
Procházka, Jan ; Niederlová, Markéta (referee) ; Bahbouh, Radvan (advisor)
The thesis brings forward an analysis of the phenomenon of life management (LM) and its research. The introduction ponders over the level of knowledge of the theme and its interpretation; the theoretical part deals with comparison of related theories or, to say it in another words, of theoretical foundations of the phenomenon of LM, taking their similarities and differences into account, where the conclusion of the thesis is that the phenomenon of life management is absolutely necessary; and the practical part deals with field research. In total, 125 subjects took part in it. The research combined various methods - interviews, life axes and questionnaires. The participants were asked to answer questions regarding the management of their own life, and the basic characteristics of it. Based on an analysis of categories, a theory of life management was laid down based on the most relevant pieces of knowledge. LM is a complex and individual phenomenon. Obviously adverse external factors, e.g. poverty, unemployment or illness, weren't necessarily signs of inadequate life management in the studied population. Mostly, the respondents associated proper life management with an idea of initiative and proper provision for themselves (or for their near relations), meeting their own goals and happiness. LM includes a...

Comparing the Price of a Transportation Structure and the Actual Costs Incurred in Various Stages of Construction
Nezbeda, Jiří ; Zímová, Štěpánka (referee) ; Kosová, Jaroslava (advisor)
This diploma thesis deals with the calculation of the cost of the building work in order to create the price, which at the stage of the contract becomes a selling price, and the costs are fixed as a budget. The subject of this work is to monitor the development of costs in time so that the cost does not exceed the budget and the construction did not get into the negative result. Then set the price by its own methods (item budget, calculation according to budget indicators) and compare the prices and costs thus obtained from different phases of construction between each other and determine the differences. In this work is monitored and compared the cost of a construction contract and its costs in the construction stages. In the practical part,is used the method of direct comparison of cost and price values over time, in the form of different outputs from the controlling program and outputs from compiled item budget and the calculation of the construction. Analyzing the differences between these costs and their evolution over time by more detailed examination of item budgets and cost calculations, they determine the origin of these deviations. In conclusion, is proposed measures for a particular transport structure whitch was handled by the author as"master and co-ordinator of the construction".
