Photocatalytic Activity of Titanium Dioxide Printed Layers
Novotná, Michaela ; Jančovičová, Viera (referee) ; Veselý, Michal (advisor)
This diploma thesis was focused on the preparation of self-cleaning and photocatalyticaly active titanium dioxide thin films. Transparent and porous thin layers of titanium dioxide were prepared from sol-gel containing titanium tetraisopropoxide (TTIP) as precursor with addition polyethylene glycol (PEG). Transparent thin layers of titanium dioxide were also prepared from colloidal solution titanium dioxide. The immobilization of thin titanium dioxide layers was performed by a sol-gel process on the soda lime glasses. Diffusion of sodium cation from soda lime glasses into titanium dioxide layer were blocked. Sol was deposited by printig method – micropiezo deposition. Sol and thin titanium dioxide layers were characterised by the physical-chemical method. For prepared sol viscosity, density and surface tension were measured. Thickness and hydrophilicity of titanium dioxide layers also were studied. The photocatalytic activity of the printed titanium layers were tested via the photocatalytic degradation of the 2,6-dichlorindophenol. The influence of addition PEG into the sol and influence of sol loading was studied. It was found that the addition of PEG into the sol significantly increased the photocatalytic activity of titanium dioxide layers.

Stanovení biogenních aminů ve víně
Novotná, Michaela
This thesis focuses on the determination of the amount of individual biogenic amines in eight samples of wines coming from four European countries – Czech Republic, Spain, Austria a Hungary. There was chosen one white and one red wine variety from each country. All of wine samples was dry – content less than 9 g sugar per liter. Varieties were: Grüner veltliner (one sample from Austria and second sample from Hungary), Chardonnay (one sample from Czech Republic and second sample from Spain), Zweigeltrebe (from Austria), Cabernet Moravia (from Czech Republic), Blauer Portugieser (from Hungary) and Tempranillo barrique (from Spain). The amount of biogenic amines was determined by ion-exchange liquid chromatography with UV/VIS detection. The bigges amount of biogenic amines was detectected in Zweigeltrebe. The lowest in Chardonnay (Czech Republic). Putrescine was detected in all samples, by contrast histamin was mostly under the detection limit.

Communication with elderly people with dementia in nursing care
Novotná, Michaela ; Kutnohorská, Jana (advisor) ; Vachková, Eva (referee)
Institution: Charles University in Prague, Faculty of Medicine in Hradec Králové Department of Non-Medical Studies Title: Communication with elderly people with dementia in nursing care Supervisor: doc. PhDr. Jana Kutnohorská, CSc. Number of pages: 107 Number of appendices: 15 Year of defense: 2023 Keywords: Communication, elderly, dementia, ethics, dignity, nursing staff, nursing care, burnout syndrome Bachelor thesis focuses on the communication of nursing staff with elderly people with dementia in nursing care. It deals with communication with respect to human dignity, and also looks at the prevention of burnout syndrome. The basis of the bachelor's thesis is a quantitative research on the way of communication of nursing staff with elderly people with dementia syndrome and methods of staff's respite from work. The personnel studied are direct nursing care workers in hospitals and homes for the elderly in a total of 11 facilities (4 hospitals and 7 homes for the elderly) in the Hradec Králové region.

Hoof disease in dairy cows
NOVOTNÁ, Michaela
The bachelor's thesis is focused on a globally problematic topic, which is hoof disease in dairy cows. The theoretical part discusses the anatomy and physiology of the thoracic and pelvic limbs, as well as the influences that affect the structure and diseases of the hoof. Infectious and non-infectious hoof diseases and prevention are also written in this chapter. In the practical part, the number of sick dairy cows and types of hoof diseases were monitored in the company AGRA Březnice a.s. 804 cows were monitoredover a period of three years, from January 2018 to December 2020. During this observation, it was found that dermatitis and ulcer diseases of the hoofs are the most common in breeding. Hoof disease affects around 50 % of dairy cows in all lactations. In sick cows, milk yield is reduced.

Assisted reproduction - legal and ethical aspects
Novotná, Michaela ; Salač, Josef (advisor) ; Šustek, Petr (referee)
Assisted reproduction - legal and ethical aspects Abstract This master's thesis discusses legal and ethical aspects of assisted reproduction. The aim of this thesis is to describe current legislation governing assisted reproduction, evaluate whether such legislation is able to meet the needs of modern society and also to discuss possible amendments thereof necessary for establishing a reasonable and effective legal system. With respect to the fact that assisted reproduction still represents a controversial topic among the general public, this thesis also deals with related ethical aspects and mentions the most contentious topics debated both in the Czech Republic and worldwide. This thesis is divided into six chapters. The first chapter explains the term assisted reproduction and describes its main principles, methods and procedures along with conditions for assisted reproduction including infertility. The second chapter of this thesis is more practical and focuses on topics related to providing assisted reproduction, such as who may provide said medical service or who may be the recipient thereof. The question of financing this medical service and its connection with the public health insurance system is also reflected. The third chapter is aimed at donorship of gametes and related aspects including...

The effect of phosphorylation in the regulation of Rho-GTPases
Novotná, Michaela ; Rösel, Daniel (advisor) ; Hála, Michal (referee)
This bachelor thesis is focused on regulating of the activity of the Rho GTPases. Rho GTPases are important signalling proteins that are involved in regulation of many cellular processes, for example dynamic cytoskeleton changes (especially actin fibres) associated with cell adhesion and migration, vesicle trafficking or cell cycle. The activity of the Rho GTPases is primarily regulated by other proteins affecting the presence GTP/GDP or by posttranslational modifications. This thesis is focused on a narrow section of these modifications, namely phosphorylations. Phosphorylation of the Rho GTPases affects for example their activity, localization, or degradation. Understanding the mechanism of regulation of Rho GTPase activity is important for comprehension of cellular processes. Rho GTPases are involved, for example, in tumour cell invasiveness. By studying Rho GTPases and their regulation, it is possible to better target potential treatment or even prevent the occurrence of the metastases.
