The regulation of brown bullhead - \kur{Ameiurus nebulosus} (Lesueur, 1819)
BLÁHA, Jan
The presence of non-native fish species is one of the causes of loss of biodiversity or even degradation of entire ecosystems. The spread of non-native species is often of invasive nature, which is accompanied by a number of direct and indirect effects on the original organisms. These species are often characterized by greater aggressiveness, resistance, growth rate, early sexual maturity period or the presence of anti predatory mechanisms. The expansion of non-native species is mostly and significantly the result of human behaviour. This bachelor thesis is focused on the possibility of regulation of Brown Bullhead or its similar relative Black Bullhead. Brown Bullhead has been present in our country since 1890. The regulation was done by the means of traps. Different kinds of baits were also used in order to maximize the efficiency and selectivity. The data on the actual occurrence of these species in the Czech Republic has been obtained based on the mapping. Historical data need to be confirmed or disproved of and an assessment of its occurrence had to be made as accurately as possible. The thesis also describes other non-native fish species currently present in the waters of the Czech Republic that can affect water ecosystems. The conclusion also contains suggestions of some preventive measures that could be taken to eliminate the possibility of further spread of non-native species of fish in the Czech Republic.

Ellagitannins -occurence, metabolism and effects on human body
Raabová, Karin ; Karlíčková, Jana (advisor) ; Martin, Jan (referee)
CHARLES UNIVERSITY PHARMACEUTICAL FACULTY IN HRADEC KRÁLOVÉ DEPARTMENT OF PHARMACEUTICAL BOTANY AND ECOLOGY Title of the Diploma thesis: ELLAGITANNINS - OCCURENCE, METABOLISM AND EFFECTS ON HUMAN BODY Candidate: Bc. Karin Raabová Supervisor: PharmDr. Jana Karlíčková, Ph.D. Diploma thesis 2016/2017, pp. 77 Ellagitannins belongs to a class of hydrolysable tannins, which are susceptible to hydrolysis to give ellagic acid in the digestive tract. Ellagitannins occur in many plant families, for example plants in the family Rosaceae, Myrtaceae or Lythraceae. There are naturally found in some fruits (pomegranate, strawberries, blackberries, raspberries, grapes), but also in the seeds of walnuts and thus form a diverse group of bioactive polyphenols with anti-inflammatory, antitumor, antioxidant and antimicrobial activity. Special instrumental methods (HPLC, DAD, MS) are most often used for subsequent evidence of occurrence of these compounds in plants and their identification. This diploma thesis is a literature review, which aimed at processing the available knowledge about the ellagitannins. Attention was focused on the biological activity demonstrated in an animal or human organism. Keywords: ellagitannins, occurrence, metabolism, effects, human body
The occurrence of the HW element in Welsh English
Kolísková, Barbora ; Skarnitzl, Radek (advisor) ; Šturm, Pavel (referee)
The aim of this diploma thesis is to investigate the accent realizations of the initial consonant in wh- words in Welsh English. The theoretical background of this study deals with the development of Welsh language and its interactions with the British standard variety. Together with the previously mentioned the phonological inventories of Welsh, RP, and Welsh English are described in the first part. We further analyzed the development of the <hw> element in the British Isles in general. The research part of this study is concerned with the analysis of the data from 20 speakers of Welsh English. Three speech styles were used for the final analysis: spontaneous speech (informal style), isolated words (formal style) and reading of Cinderella (formal style). Signal-to-noise ratio and voicing of the <hw> segments were measured in order to discover the occurrence and the nature of the <hw> element. The lowest levels of harmonicity were measured in segments that were obtained from the formal reading style. The highest levels were measures in the spontaneous speech tokens. Younger speakers showed higher levels of harmonicity than older speakers. The results of the male and the female participants were different in each type. In the spontaneous speech style the male speakers tended to have lower levels of...
Loriini - trade, captive breeding, distribution pattern
HOSPŮDKOVÁ, Hana
This project concerns with making data about numbers of populár lories in wildlife, their biology, protection and threat. Timespace evolution of legendary business was rated from 1981 2013 with using of CITES database. The results are evaluated within the framework of export, import, commoditis, purpose of trade and source of specimens. It was found out that the biggest business was with a live specimens, the most often reason was commercial and ancestry all animals was kept in captivity. Singapore, USA and Japan belonged between main importers. Indonesia, Singapore and South Africa were main exporters. Trichoglossus haematodus and Eos rubra were main kind of animals for business. The biggest success in this industry was registered in 1990 and then less in 1991 and 2005.
The Incidence of Pertussis in South Bohemia
HOLINKOVÁ, Petra
The thesis deals with the problem of the occurrence of whooping cough in the South Bohemian Region in the period of 2003-2012. Despite the high level of vaccination the incidence of this illness after a significant fall in the 1980s has been growing constantly since 1993. This trend evidently also applies in other developed countries with a high rate of vaccination. The main aim is to draw up an overview of the occurrence of whooping cough in the South Bohemian Region in the monitored period of the last 10 years, compare this occurrence with other regions in the Czech Republic and map out the changes which have occurred in whooping cough vaccination. Quantitative and qualitative research was chosen to process the empirical part. Data for quantitative research was acquired from the database of infectious diseases (EPIDAT), and consisted of reported cases of whooping cough. Another essential group of data were demographic figures about the number and age structure of the population. The second qualitative part was drawn up on the basis of a literary search. I acquired additional information by communicating with individual territorial workplaces of the Regional Hygiene Station of the South Bohemian Region based in České Budějovice. Using the processed data I discovered that the incidence of whooping cough in the South Bohemian Region does not have an ascending trend in 2003-2012 unlike the trend in the whole of the Czech Republic. The highest occurrence of whooping cough in the Czech Republic in the monitored period was reported in the 10-14 age group. The research also showed that in the period of 2003-2012 individual regions differed greatly in the occurrence and can be divided into two groups ? regions with the highest reached incidence below 10 cases/100,000 people and regions with incidence with the highest reached incidence above 10 cases/100,000 people which includes the South Bohemian Region. There have been many changes in the vaccination of whooping cough and the most important was the transition from whole cell vaccine to acellular in 2007 and adding a 6th booster dose between the 10th and 11th year in 2009. The greatest attention should be paid above all to increase information or test the knowledge of the lay public, especially women preparing for pregnancy and people taking care of newborn babies and infants about the occurrence, potential risks and possibilities of vaccination against this infection even at an adult age. In my opinion a further necessity is the consolidation of diagnostics, definition of a case and procedures of surveillance throughout the Czech Republic, education of paediatricians and general practitioners about the illness and topicality of the problem, an appeal to report the occurrence of this infection to epidemiologists, observing the isolation of the patient, monitoring possible epidemiological connections between cases and making use of the offer of the NRL (National Reference Laboratory) services against whooping cough and diphtheria. This thesis can be used in practice as a summary of information material for the lay and professional public about the occurrence of whooping cough in the South Bohemian Region and throughout the Czech Republic and overview of vaccination against whooping cough. It can be an incentive for further anti-epidemic measures and the need for further research into this problem.
The occurrence of weed control methods in stands of grasses spring cereals
SLABÁ, Jiřina
This work focused on the problems of weed plants in spring cereals on plots of agricultural cooperative Čížová. The company is located in South Bohemia, 5 km from Písek. The evaluation of weed infestation was made by numerical method in period from spring 2011 to summer 2011. The issue of weed plants is one of the main negative factors affecting yield and grain quality. Number of weed plants, which at a given location occurred, was regularly observed and evaluated. The most commonly occurring weeds were Viola arvensis, which made up approximately 50 % of all the range of weeds which occurred in the explored land. Other significant weeds were Thlaspi arvense L. and Capsella bursa-pastoris L. We can suppose that Viola arvensis will be a problematic weed. The conclusions can be stated that long-term regulation against the occurrence of perennial weeds must be done carefully and must be based on complete protection which consists of direct and indirect methods of weed control products. Underestimating the occurrence of weeds in crops can cause serious problems.
