Determination of total antioxidation activity of tea pickles in selected sorts of tea
Bartošová, Jitka ; Vitoulová, Eva (referee) ; RNDr.Jana Skopalová, Ph.D. (advisor)
This thesis deals with the total antioxidant activity (TAA) evaluation of various sorts of tea (green, black, half-fermented, white, mate, rooibos and herbal) depending on the process and time of their treatment. The main emphasis is put on testing a new method of measuring the total antioxidant activity by flow coulometry. The results acquired by this method are compared to the results of the chemiluminescent Trolox equivalent antioxidant capacity (TEAC) method which is a standard for measuring the total antioxidant capacity in various materials and raw materials. The work discusses the reasons for the differences in the values found by both methods.

Effects of human demonstrator on horse's performance in a spatial task: Does social learning occur?
Pokorná, Miroslava ; Bartošová, Jitka (advisor) ; Fuchs, Roman (referee)
Social observational learning is one of learning abilities expected in domestic horses (Equus caballus) because of their ecological and evolutional history. However, a few studies focused on this type of learning in horses failed to provide clear evidence of observational learning and/or could not distinguished it from other types of learning. We tested interspecific observational learning abilities using the spatial task and a human demonstrator. We hypothesised that 1) horses with possibility of observing a human demonstrator will complete the task in shorter time than control horses without any demonstrator, and 2) horses observing a familiar demonstrator will carry out the task in shorter time than horses with an unfamiliar demonstrator due to established positive human - horse relationship. Twenty - four riding horses of mixed age and breed were randomly allocated to three groups per 8 and started the task either with observing a familiar demonstrator, unfamiliar demonstrator or no demonstrator (control group). Each horse was released individually at the starting point in the experimental paddock and the latency to pass the task was recorded. A horse completed the task once it walked 25 m from the starting point to the squared area (4x4 m) fenced by a tape, went into it through the entrance on the...

Studie možnosti obnovy malé vodní nádrže v k.ú. Pavlov
Bartošová, Jitka
This bachelor thesis deals with the possibility of recovery of a small water basin in Pavlov register. The base of this thesis is based on literature research associated with this theme, assessment of natural conditions and copious terrain exploration. Current flow and flow within ten years period are also determined. Plan of a small lateral water basin is then created based on these facts. The thesis also deals with the connection to the territorial system of ecological stability and the possibilities of how to fund this project as well as the alternative draft of pools and wetland.

Real Convergence of Economies
Sobotková, Kateřina ; Bartošová, Jitka (advisor)
The diploma thesis deals with the analysis of the convergence of the Czech Republic and selected countries of the former Eastern Bloc over a long time period (2004-2015) based on the macroeconomic indicator GDP. In the practical part, the data is first introduced and the Solow model is compiled for all countries. Development of GDP per capita over time is also graphically illustrated using basic indices. The main part of the diploma thesis is the implementation of convergence or divergence analysis using the concept of beta and sigma convergence and the convergence method in absolute and relative differences. Sigma convergence is based on standard deviations and variation coefficients. For both variants, the time period is divided into two parts causing different results.

Statistics and its Utilization (Abuse) in Gaining Information
Baumann, Martin ; Bartošová, Jitka (advisor)
Public opinion is formed in couple phases which are linked to each other. However, some specific information or happening, which a given member of society or a given part of population faces, stands every time at the beginning. Constantly increasing opportunities of data gaining, processing and analysing enable a creation of information about various areas of human activities. This information plays a significant role in the process of public-opinion creation. For data analysis, various elements of statistics are used. A thesis deals with the opportunities of utilization of statistics for creation and spreading of information. A theoretical part of the thesis deals with knowledge of public opinion area and statistics. In practical part of the thesis, mostly used methods for intentional or unconscious manipulation with public opinion are presented. The main element of the practical part of the thesis is the formation of a questionnaire survey and the analysis of its data. The cardinal research hypothesis of the thesis is a discovery, if the knowledge of statistic terms affects the ability of respondent to interpret an information message.
