Transfer of genetic information between parasite and its host
Soukal, Petr ; Hampl, Vladimír (advisor) ; Votýpka, Jan (referee)
Horizontal gene transfer (HGT) is considered a rare evolutionary event. It can take place between unrelated organisms that coexist in an intimate symbiotic relationship. Such relationship have some parasites with its host. HGT between eukaryotic parasite and its host was identified in some holoparazitic and hemiparazitic plants, the most important human protozoan parasites, microsporidias, human blood-flukes, parasitoids and fruit flies.

Evolution of molecular interaction between host and parasite
Bílková, Barbora ; Vinkler, Michal (advisor) ; Synek, Petr (referee)
Coevolution between host and parasite is a long-term object of scientific interest, mostly because of negative influence of parasites and human need to defend against it., The evidence concerning host-parasite coevolution mechanisms is, however, still incomplete and various models and theories are considered separately, out of the general concept. Beside generally well-known theories such as the "Red queen" theory or the coevolution "arms race" theory, several other models were proposed, e.g. the "gene for gene" model or the "matching allele" model, which describe detailed aspects of host-parasite coevolution and principles of genetic variability maintenance in their interaction. Although there are many studies mapping reciprocal evolution of hosts and parasites, the connection between empirical evidence and theoretical models is often missing. Therefore, this thesis covers theory on host-parasite evolutionary interactions and provides examples of host-parasite systems and molecules, which correspond to behavior of described models.

What is criticism, what is not and what use is in the world. Typology of Czech literary criticism in the years 1995-2008
Proroková, Marie ; Kubíček, Tomáš (advisor) ; Peterka, Josef (referee)
This bachelor's thesis describes the development of literary criticism conception and it's earlier typology. The thesis deals with the difference between literary criticism and reviews - how these dissimilarities appear in theory and in practice. The applicable typology for present Czech literary criticism has been suggested in this thesis. The typology mentioned divides literary criticism into two main types: text-oriented criticism and context-oriented criticism. It discusses the development of value conception and what is a value even nowadays. For contemporary literary critics it is originality, credibility of the work and composition. It provides information on how criticism is presented by individual Czech periodicals including Host, A2, Revolver Revue, Tvar, Souvislosti and Literární noviny.

Extending Access Control List in Dokuwiki
Macháč, Ondřej ; Kočí, Radek (referee) ; Smrčka, Aleš (advisor)
The goal of this bachelor thesis is to introduce the Wiki systems, especially DokuWiki. It deals with history, legal aspects and possibility to create pluggable modules (alias plugins). Plugins are also main theme of this work. At first, a simple plugin for user access rights is designed. Afterwards is extended plugin's functionality with advanced settings of permissions and is also created the ability of automatic user login based on specific entry informations.

Optimization of network position prediction
Pospíšil, Petr ; Pfeifer, Václav (referee) ; Burget, Radim (advisor)
This work is about position prediction in network, it is focused to find Landmark closest to the Host in the network (with lowest distance vector). The algorithm is based on GNP system. In terms of GNP system simulation was selected method for mathematical part of position prediction. The method was Simplex Downhill. The designed algorithm was implemented in Java. In the first step chose Host continent by meassuring the distance vector. In next step is selected nearest part in the continent. In conclusion estimate Host its position and then closest Landmark. Results from this work is important for designing TTP protocol. The verdict is that the GNP can be used for TTP, but Landmarks must be located in uniform density.

Communication problems between hotel staff and guest
Holíková, Sandra ; Jenčková, Jiřina (advisor) ; Voříšková, Barbora (referee)
Bachelor's thesis deals with communication problems that may occur between hotel staff and a guest. Theoretical part is focused on explaining of terms communication, hotel staff and hotel guest and following division into categories. Furthermore, theoretical part includes general rules of proper communication, separately for personal, telephone, written and intercultural communication. Practical part is dedicated to particular crisis situations that may occur in the hotel, their possible proper solution and questionnaire prepared for receptionists.

Detection of cryptosporidia by means of molecular methods in clinical samples:infection or the transit of oocyst through the host gastrointestinal tract?
MUNZAROVÁ, Lucie
Representatives of the Cryptosporidium family are, from a medical and veterinary aspect, designated as important unicellular parasitic protozoa infecting all classes of vertebrates including humans. Their development cycle is monoxene, which means that its life cycle is completed uniquely in one host. Their exogenous stages of infection development ? oocysts ? are mostly secreted in faeces causing a parasitic disease called Cryptosporidiosis. Generally, it is assumed that isolated cryptosporidia from one class of vertebrates are not contagious for other hosts from different classes, and also, that the majority of cryptosporidia types and genotypes have low host specifity. However, there are many cases where the presence of oocysts was proved, or the presence of specific cryptosporidium DNA in faeces of atypical hosts. With regard to the fact that the majority of genotypes and their potential hosts were described only on the basis of the presence of the specific cryptosporidium DNA in faeces, the question arises as to whether the aforementioned hosts are in all cases perceptive to the given infection, or it was only contamination in a sample or the transit of oocysts through the host gastrointestinal tract. This issue is also characterised as being the main objective of this thesis. The study gives an appropriate answer to this question by a series of experiments. Different isolations of cryptosporidia were used for experimental infection of rodents which were per orally infected and put down after reaching the specified patent period. By means of the combination of standard parasitological and molecular methods, the presence of oocysts and specific DNA of cryptosporidia in faeces and in mucous membrane of the gastrointestinal tract of infected hosts was observed. The results of this study prove that the transit of oocysts through the gastrointestinal tract can be detected in the interval between 6 and 24 hours after infection, yet not in every case. On the basis of this finding, the first hypothesis which stated that it is not possible to qualify explicitly by detection of a specific cryptosporidium DNA in faeces whether the infection has begun in the host or it is the transit of oocysts through the host gastrointestinal tract, was thus partially proved. On the other hand the second hypothesis stating that the specific cryptosporidium DNA in clinical samples of faeces can be detected only in cases of the host´s successful infection, was rejected.

Host (do domu), the journal of literature under politic pressure and against it and its contemporary appearance
NAJBRTOVÁ, Barbora
The bachelor labour conserns about the research of Host do domu, the journal published between years 1954 and 1970, and its subsequent continuation after 1999 till the present. The work deals with czech cultural context as well as with the historic circumstances, which the journal react to. The main aim is firstly to analyze the present copies, which has been published in the last years since today. Secondly, the work compares the ralation between both of the homonymic journal in order to find out how was the Host oscillating. The folowing research inquires into the interpretation of the journal's charakteristic attributes.

The classification of accommodation facilities in the Czech Republic and foreign countries
KOHOUTOVÁ, Klára
The aim of my thesis is to aprise the reader with the meaning and purpose of classification of accommodation in the Czech Republic. I am trying to compare the classification of 2009 with the present classification valid since 2010 till 2012 but also with classifications of other countries. For this comparison I chose the classification of the accommodation in Great Britain which is according my opinion very detailed but also with the classification of other, mainly European countries (with the American classification I compare the classification only in general terms).
