Laser Doppler anemometry
Osička, Tomáš ; Lízal, František (referee) ; Jedelský, Jan (advisor)
This bachelor thesis deals with laser Doppler anemometry (LDA). It is a modern, non-intrusive flow measurement technique. The work deals with theoretical principles and components of the method. The experimental part is devoted to setting of the system. Vector plot and profile plot display the measurement results.

Faux amis in German and in English
KALOVÁ, Michaela
This bachelor thesis deals with the topic "Faux amis in German and in English". This thesis is primarily focused on the semantic faux amis which could pupils in the Czech Republic meet with. The theoretical part defines the basic terminology related to so called false friends. Furthermore, the theoretical part clarifies the formation and classification of faux amis. The practical part contains the gathered semantic faux amis which are classified in the reference levels according to the Common European Framework of Reference for Languages (CEFR). The lists of faux amis of individual levels are in the practical part further analysed.

Typical grammar errors in text production committed by Czech learners of German-as-a-Foreign-Language - a quantitative and qualitative corpus analysis.
BARTÁKOVÁ, Stanislava
This thesis is divided into two parts a theoretical and a practical one. The main topics of the thesis are the most common grammar mistakes of Czech pupils who learn German as a foreign language. The theoretical part explains terms such as mistake, error or contrastive linguistics, categorizes the errors and presents the reasons for those errors. The main part consists of a corpus analysis of texts written by Czech learners. Their errors are analysed, compared and explained. Graphics show the development of those errors in different learning process stages. Last but not least a questionnaire to explore the teachers' awareness of those errors and their correction will be provided.

A design of the system for continous evaluation of analytical samples quality in a clinical biochemistry laboratory
SVATOŠOVÁ, Kristýna
The aim of my work is to provide information about the process of evaluating analytic quality of samples. This kind of process is recommended in clinic biochemistry laboratory at present. Serum indexes are measured always, in any required sample test whose result can be influenced by sample quality. It is possible to evaluate the degree of haemolysis, icterus and lipemia in patients´ blood samples by the photometric method. The sample haemolysis is mostly caused by bad technic of blood samples taking or their inappropriate transport so that in the end of this process, in regular intervals there is a possibility to find out the level of results changes in connection with concrete laboratory services users. In theoretical part of my work I describe reasons of sample quality decreasing in vivo that´s something people can´t influence because they originate in a patient´s body and in vitro that are caused by wasteful manipulation. In this part there are also principles of the photometrical methods mostly used. The practical part contains the model example that shows how the analyts can be influenced by artificial adding of interfering substances. I could see increasing of some element concentration after making evaluation: Concentration of K increased by 24%, Fe by 10%, bilirubin by 13% and enzymatic activity ALT by 23%, AST by 179%, GMT by 26% and ALP was reduced by 25% in haemolytic serum. In icteric and lipemic serum there isn´t interference on such high level. Icterus causes decreasing of urea by 17%, creatinine by 27%, enzymatic activity ALT by 10% and activity GMT is increased by 11%. Lipemia decreases concentration of creatinine by 8%, enzymatic activity ALT by 6% and bilirubin is higher by 21%. In the end of my work I introduce statistic conclusion laboratory informatics system that gives laboratory management possibility to find out samples of bad quality in connection with concrete applicants and help to make some reparation.
