The influence of a pre-print thick layer paste viscosity on forming of layer
Ondráček, Michal ; Švecová, Olga (referee) ; Klíma, Martin (advisor)
This bachelor thesis deals with the theory of thick film technology and applying these layers. The work also includes basics of liquid rheology, methods of measurement viscosity and ways of mixing liquids. The main aim is to determine the influence of viscosity of thick film pastes for printing quality of the test structure using screen printing, in particular its flatness and sharpness. The aim is also measure the dependence of viscosity thick film pastes on mixing time.

Dielectric properties of liquid insulators
Jahn, Michal ; Starý, Jiří (referee) ; Špinka, Jiří (advisor)
This master‘s thesis deals with measurement of liquid dielectric materials (insulators). Above all, it is the different kinds of clean and drinking water, but also transformer oils. There was done theoretical information retrieval about the given topic in this project and on the basis of theory there were realized the relevant measurements of selected properties of liquid dielectric, such as permittivity, capacitance, loss number, conductivity, but also temperature dependence of these parameters. The measurements were realized with the help of product manufactured at the faculty FEKT VUT and with the help of measuring system AGILENT 16452A. The measured results were evaluated, graphically processed and compared.

Uncertainties of measurements of the dynamic viscosity
Januš, Petr ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
The thesis is deal with measuring the temperature dependence of dynamic viscosity and the calculation of measurement uncertainties. The thesis writes up the physical nature of viscosity and rheological properties. Next it is write up an overview of possible methods for measuring viscosity of liquids and overview of methods for measuring the density of liquids. An important chapter is the statistical evaluation of measured data represented mainly measurement uncertainties. In the practical part of the work is done workplace for measure the temperature dependence of dynamic viscosity. It is used two methods of measuring viscosity of liquids and two samples of liquids. Finally is done statistical evaluations of measurement. Based on the calculated measurement uncertainty measurement methods are compared.

The meaning of hydratation old people from the perspective of nurses
GRIMM, Viktor
The aim of the bachelor work is to fulfill the following: 1. to research the nurses´knowledge of seniors´ hydratation, 2. to research the nurses´procedure of monitoring the seniors´hydratation and 3. to research the nurses´role in seniors´care concerning hydratation. To achieve the aims mentioned there have been seven research questions to be answered: What is the nurses´ knowledge in the field of hydratation?, How do nurses keep their knowledge and how do they extend it? Are there any significant differences as for maintaining and upgrading knowledge regarding hydratation among nurses of individual units? What are the hydratation signs nurses monitor and evaluate? Are there any differences as for the seniors´hydration procedures among nurses of individual units? What interventions concerning seniors´ hydratation care do nurses carry out? And How do nurses perceive their part of care connected with seniors´liquid intake? To get valuable information for the empiric part of the work there has been carried out a qualitative research method for which a semi-structured dialogue has been used.This dialogue included 22 open questions which were completed by follow-up questions if necessary, see the attachment 1.The questions were aimed at the following: what do nurses monitor while taking care of seniors in danger of hydratation, what are the key interventions the nurses carry out but also if they are being educated in this field and how important do they consider their part. The respondents were 6 general nurses who provide care for geriatric patients endangered by dehydratation. To analyse the research results the method of open coding, pencil-paper, was used. For better orientation the research results have been put into four main categories and several sub-categories. These logically created categories were set to deal with individual hydratation issues from the nurses´point of view, complexly, taking wider circumstances into consideration including nurses´education and their personal opinions on this topic.Thank to opinions of the general nurses, the most competent ones, the work´s results provide us with a complex view on the matter and that is why it can be used as the source of information not only for students, hospital attendants and nurses but also for common people who look after a senior at home and that is why they are highly interested in this issue.

SENIORS´DRINKABLE REGIME CONSIDERIN the PRODUCT ASSORTMENT and PARTICULAR SEASON
SVOBODOVÁ, Michala
This diploma work is aimed at the basic information about the importance of the drinkable regime especially at elderly people and at the topic of the drinkable regime at seniors in collective facilities in general. The theoretical part contents information about the process of human organism ageing and about the importance of the drinkable regime in senior age. It solves health consequences while the drinkable regime is not being kept sufficiently and it specifies the drinkable regime in senior age during hot and colder periods of the year. In particular chapters there are specified different kinds of water, their elements, particular parts of beverages and their pertinence for the senior population. The practical part analyses the results of the research that was performed by means of anonymous questionnaires in the facilities for seniors and in hospitals for patients under long-term treatment. These questionnaires are aimed at the frequency, amount and the assortment of the consumed beverages in particular periods of the year and it should reveal if the seniors are well informed about the drinkable regime in connection with their health condition. The research has proved that seniors are sufficiently informed about the principles of the drinkable regime but they are often limited by the financial situation or by the level of their self-support.
