Selected factors affecting the performance of racehorses
Jirásková, Petra ; Vostrý, Luboš (advisor) ; Karel, Karel (referee)
The aim of this thesis is the selection of most significant factors influencing the performance of racehorses and a subsequent analysis of selected factors in terms of influence on the performance of racehorses in the Czech Republic. Furthermore, the scientific hypothesis was that the obtained databases would allow for an exact analysis of the influence concerning selected factors (gender, age, season of birth and others) on the performance of racehorses in the Czech Republic
The horses´ performance depends on a larger number of factors, which can be divided into two groups. The first group is the internal factors (genetic preconditions, build, constitution, temperament and character) and the second group is external factors, i.e. factors influenced by the environment and independent of a horse. The conditions of the environment along with the horses´genotype influence horses´performace the most.
There is a wide range of external factors, e.g. season in which the horse was born, weight at birth, rearing of a foal, preventative health care, nutrition, moving regime, training, conditions of a particular race, the impact of age and gender.
The aim of this thesis was to evaluate the influence of selected factors on the performance. The general handicap has been used as the basic indicator of performance in individual horses, which is the performance evaluation of a horse in races in a particular year. The final database has been created in Excel, in which some calculations and graphs have been carried out as well. The very statistical processing has been done in the R program.
The influence of the birth season, gender and age on the horses´ performance has been gradually evaluated. It has been found that in two-year horses the birth period significantly influences the age when starting races for the first time (i.e. the later the horses were born, the earlier they were able to start racing). Moreover, a connection between the amount of prize money and the gender in two-year horses has been found, with mares reaching higher prize money. A lower number of days from the birth to the first start in a race has been found in mares. An interesting connection has been found between the age of the first start and the general handicap rate (participating in the first race at the age of two had a positive influence on the handicap rate at the age of three.)

Analysis of sheep utility attributes in Valachian sheep in selected flock.
Habětínová, Kateřina ; Ptáček, Martin (advisor) ; Jan, Jan (referee)
The aim of my Diploma thesis was to evaluate a basic reproductive, milky and growth characters of sheep tribe Wallachian sheep in the chosen facility. The monitoring of the reproductive fiures has been made in years 2012, 2013 and 2014. There have not been shown any results for the year 2015, that is why these particular figures are not explicit. The measures of reproductive figures of Wallachian sheep were compared to the average of Czech republic. The evaluation of the figures given at the chosen farm has had a good results in all four evaluated figures (fertilization, fertility, intensity and nursling).
The evaluation of an utility value processed in 2015. The milk production in order of the milk utility value (% fat, % proteins, % kasein, % lactose, % TPS, % solilds) has been dependent from the authority of mother sheep as well as the influence of the countability of farrow.
The influence of mother sheep´s age on the milk production has had a demonstrable influence mainly on the milk sicking and the percentage of fatty solids (TPS). The best results have been achieved on three aged sheep and the worst results on five aged sheep. At the percentage of proteins and kasein there has also been fount the explicit impact of mother´s age. Differences have been measured also on the fat percentage, milk and solid with a statistically provable measures.
The impact of a farrow´s countability on the milk utility has been proved in milk sicking. Mothers with geminus sicked in average 93 g milk more. This difference was apparent on the level of detectability P < 0,05.
The evaluation of meat utility processed in the year 2015 where the birth weight of lambs and their growth abilities (40, 70, 100 and 140 days of age) were measured.
Sex influence on meat utility has been statistically demonstrable on the weight at the age of 70 and 140 days. In both cases the fleeces showed biger weight. Also another measurements have showed the gaps between the weight of fleeces and lambs on the fleeces´s behalf.
The mother´s age influence on meat utility has not been statistically proved in any of figures although the measured figures have been slightly rising.
The results can serve as a preparation or adaptation of these sheep cultivation as well as an improvement of their utility.

Sperm phenotype and it's relationship to individual condition
Köstelová, Linda ; Svobodová, Jana (advisor) ; Pavlína, Pavlína (referee)
Animals are known to have evolved many different characters in order to improve their chances during the sexual selection. These secondary sexual characters should correlate with given male´s quality of ejaculate, according to previous research. The literal part of this paper shows us, that the longer the sperm was, the faster, more viable and agile it was. There was a connection between the viability and the length of the middle part of the sperm, that holds the mitochondria. At the same time, sperms with longer tails were faster, as oppose to those with bigger heads, that were slower. This paper was meant to clarify the influence the sperm phenotype on male's ejaculate. For this paper, which focuses on Great tit, the sperm length was chosen as the character of quality. Not only the length of the whole sperm, but also the length of all of its parts were measured. Every one of these parts is associated with the movement and the viability of the sperm in its own way. We tested whether the length of the sperm correlates with characters of the condition or not. The characters we had chosen for this were the length of melanine ornament, the weight of the male, the length of tars and number of leukocytes in blood. The results show that the length of the sperm head correlates with the length of melanine ornament of Great tit. We did not find any other connection among the other secondary sexual characters we had chosen.

The quality of water sources in the Czech Republic
Boháčová, Tereza ; Petrtýl, Miloslav (advisor) ; Kyriánová, Iveta Angela (referee)
The following bachelor thesis on the subject of The quality of water sources in the Czech Republic is supposed to introduce its readers to both historical development and current state of surface water quality in the Czech Republic. The works methodology is creation of a literature review of available scientific literature and especially Reports on surface water quality in particular river basins. The first part briefly describes Czech hydrological network and basic water quality indicators. The second part deals with the development of surface water quality in particular river basins. Another part of the work describes legal measures concerning surface water protection.
In the last century, surface water contamination was considered one of the biggest environmental problems in our country. Waste water flowing into surface water were not perfectly treated and often werent treated at all. Because of this and also because of intense industry development, surface water was highly polluted. It wasnt until 1989, when the surface water quality improved significantly, mainly due to reduction of contaminants discharge, waste water treatment plants and sewerage system construction and development. Main danger for quality of rivers after 1989 were floods in 1997 and 2002, during which water treatment plants outage were often and dangerous chemicals were leaking from factories.
The main finding of this work is the fact that quality of surface water in Czech Republic is much better than in the last century. However, it is still needed, that we focus on smaller rivers which are being endangered the most by discharge of contaminants from villages that dont have their own waste water treatment plants.

The Influence of the Basic Training of Soldiers on the Growth of their Physical Performance
Petrovský, Luděk ; Přívětivý, Lubomír (advisor) ; Hanák, Petr (referee)
Title: The Influence of the Basic Training of Soldiers on the Growth of Their Physical Performance Aim: The purpose of this work is to find out and verify in practice whether the basic training in the Armed Forces influences favourably the growth ofphysical performance, and to suggest possible changes in the system of the basic military training that lead to increase its efficiency. Method: The objects of the monitoring were the basic somatic indicators (height, weight and BMI) and tests of physical performance (running for 12 minutes, free style swimming for 300 metres, sít ups in 1 minute, push ups in 30 seconds, repeated pull-ups and ajumping- acrobatic exercise). During the basic training, the soldiers were tested by a test battery, which combines six motoric tests used in annual physical testing. The results of all individua! tests were processed statistically and further analyzed. Results: The research has showed that a three-month basic training influences positively the growth of the physical performance of soldiers. I have noticed an increase of physical performance, even though the basic rules of sports training theory conceming the nutrition, hygiene, regeneration and recuperation had not been kept. I can claim that soldiers who have gone through this demanding training are physically...

Measurement of ECG signal for TWA analysis
Řezáč, Petr ; Vítek, Martin (referee) ; Kozumplík, Jiří (advisor)
The thesis deals with possibilities of using wavelet transform in the field of surface electrocardiogram (ECG) signals denoising and ECG signals measuring. Several algorithms have been used to detect and estimate T-wave alternans (TWA), such as spectral method (SM), Poincaré Mapping (PM) or correlation method (CM). T-wave alternans, also called repolarization alternans, is a phenomenon appearing in the electrocardiogram as a consistent fluctuation in the repolarization morphology on every-other-beat basis. Electrical TWA has been recognized as a marker of electrical instability, and has been shown to be related with patients at increased risk for ventricular arrhytmias. Presence of TWA has been reported in a wide range of clinical and experimental situations including long QT syndrome, myocardial infarction, angina pectoris, acute ischemia, etc. Projected methods of detection TWA are realized in Matlab software, and they are experimentally verified on real ECG signals from the European ST-T Database.

The impact of digestate fertilisation on the structure of yield and selected qualitative indicators of potatoes.
Polák, Miloslav ; Hamouz, Karel (advisor) ; Pavel, Pavel (referee)
The thesis studies the effect of digestate fertilisers on the structure of yield, starch content and scab of potato tubers. The introduction outlines the problems of potato fertilisation, including the existing knowledge on the fertilisation by digestate. The subsequent, experimental part was executed in the form of a field experiment in SENAGRO Senožaty a.s. This enterprise produces table potatoes for TESCO chain of supermarkets. The company was interested in using the waste material (digestate) from biogas station as efficiently as possible and tried to use it as a dose of nitrogen under potatoes. The company uses the technology of destoning with a line width of 90 cm.
The experiment was carried out in such a way to enable to determine the effectiveness of digestate as a substitute for the usual N fertiliser for potatoes. It was based on three variants: Variant A. Ammonium sulphate applied areally before destoning and 15-15-15 local application of NPK fertiliser (in total dose of 100 kg N/ha). Variant B. Ammonium sulphate + NPK + DAM 390 applied during vegetation on 27th May 2015 (in total dose of 120 kg N/ha). Variant C. Digestate in quantity of 120 kg N/ha. Early to midseason Luciana variety was used in the experiment.
In compliance with the methodology, before the harvest I dag away the bushes to find out the level of yielding elements. I took samples that were evaluated in terms of starch content in Vesa Velhartice, and personally examined the scab of potato tubers. On the basis of statistical evaluation of the examined variants (executed at the Department of Crop Production), I reached the following findings:
Compared to the usual variants of N fertilisation, digestate fertilisation of potatoes did not have any statistically significant effect on the weight of tubers under one bush or the weight of table potatoes. Compared to the control variants of N fertilisation, digestate fertilisation did not influence verifiably the total number of tubers per one bush or the number of table potatoes per one bush. In terms of the effect on the average weight of one potato, the variant
with the application of digestate fully equalled, or even exceeded, the experimental variants of mineral N fertilisation. It is therefore possible to say that in terms of yield, this type of fertilisation can serve as a substitute of fertilisation by nitrate and mineral fertilisers. Starch content and scab of potato tubers were not demonstrably influenced by digestate fertilising compared to traditional N fertilisation.
In conclusion, I would like to point out that the experiment has been carried out only for one year and its results cannot be generalised yet. That is why I recommend to continue in the experiment also in the future years.
In my opinion, digestate and the problem with its application is becoming an increasingly pressing theme. If experiments carried out for several years prove that the result of its application is positive to potatoes, digestate, in my opinion, will again have broader possibilities of use and we can count with it as a full-value fertiliser also in the future.
Keywords: potatoes, digestate, starch content, scab, yield

Composite indicators: the construction, usage and interpretation
Hudrlíková, Lenka ; Fischer, Jakub (advisor) ; Čadil, Jan (referee) ; Hužvár, Miroslav (referee)
This thesis brings a comprehensive view on the construction, usage and interpretation of composite indicators. Methods and techniques, which can be used for constructing composite indicators, are introduced. The focus is on their contribution to the transparent solution of the problem of correlation and compensability among underlying indicators. Transparency in construction of composite indicators is a crucial requirement for obtaining reliable results and their correct interpretation. The thesis consists of two main parts. The first part is theoretically oriented. First, the problem of adequacy and subsequently a measurement of the phenomenon by means of statistical indicators are discussed. Different methods for data normalization, setting a weighting scheme and aggregation are introduced and compared. These three steps are considered to be crucial in a process of constructing a composite indicator and thus, they are the core of the thesis. The aim is to investigate an interaction of normalization methods, weight-setting and aggregation methods, since these steps are not separate. The second part of the thesis consists of two comprehensive cases. Theoretical findings are applied and empirically verified in these cases. I investigated a robustness of the composite indicator depending on a combination of selected methods of normalization, setting weights and aggregation on a set of Europe 2020 indicators. Whereas this first case dealt with the comparative analysis of methods, the second case is focused purely on one issue -- university ranking. The proposed method reacts to criticism of currently published university rankings and takes into account specifics of the particular university as well as the exogenous background characteristics. The main added value rests in a contribution to a discussion about the improvement of construction and overall quality of composite indicators including their interpretation. I pointed out the main concerns and difficulties of composite indicators that often remain unnoticed by users and even constructors. The conclusion brings several beneficial findings, which can be used for the construction of a composite indicator and an interpretation of final scores and ranking. This work can also serve as a scientific ground for further research and development of the methodology of constructing composite indicators.
