Assessment of Company Financial Situation Using Time Series
Dvořák, Václav ; Štěpánková, Vladěna (referee) ; Novotná, Veronika (advisor)
This bachelor’s thesis focuses on the use of statistical methods in practice, especially interested in the financial analysis of HELIX Liberec s.r.o. expressed by selected economic indicators in the time series from 2000 to 2010. The work has both theoretical and practical parts. The theoretical part is important to clarify the terms of the statistical and financial analysis in the practical part will apply the theoretical basis for undertaking an assessment of the situation and outline possible recommendations for improvement.

Use of Statistical Methods for Assessment of the Financial Company Performance
Dvořák, Václav ; Štěpánková, Vladěna (referee) ; Doubravský, Karel (advisor)
This thesis deals with the use of statistical methods in practice. From the field of statistics is the work of regression analysis and time series analysis, which brought to a critical assessment of the financial situation of the company HELIX Liberec, s.r.o. The work is divided into theoretical and practical parts. The theoretical part focuses on explanations of important terms of statistical and financial analyzes that are subsequently applied in the practical part. Finally, the practical part are assessed and proposals to improve the economic situation.

Production and elimination of superoxide radical in relation to the compatibility of snails and trematodes
Cibulková, Lucie ; Skála, Vladimír (advisor) ; Nývltová, Eva (referee)
Almost all trematodes use snails as the intermediate host in their life cycles. To survive within the host, they have to efficiently avoid defense reactions of its immune system. The most important effector cells, haemocytes, produce reactive oxygen species with the first molecule known as superoxide radical. Various snail species produce different levels of these radicals in relation to the compatibility with the invasive trematode species. The parasite decreases the levels of toxic radicals by using antioxidant enzymes including superoxide dismutase which catalyzes transformation of superoxide radical into hydrogen peroxide. This dismutation reaction is the first step during the oxidative burst and likely influences survival of trematodes within the host. Based on the current knowledge the production and elimination of superoxide radical in relation to the compatibility between snails and trematodes have been described thoroughly for a few models such as for example Biomphalaria glabrata-Schistosoma mansoni. However, this interaction appears to play a key role and, therefore, it deserves more attention in another models as well. Key words: trematodes, snails, compatibility, haemocytes, oxidative burst, antioxidant enzymes, superoxide dismutase, superoxide radical

Larval Stages of Flukes (Platyhelmintes: Trematoda) in Secondary School Education
Šulcová, Hana ; Říhová, Dagmar (advisor) ; Podroužková, Štěpánka (referee)
The parasites are one of the most important factors that shape relationships in the nature. This thesis deals mainly with developmental stages of trematodes (Platyhelmintes: Trematoda), especially the cercariae of so-called Schistosomes and sporocysts of Leucochloridium paradoxum, as well as with and their intermediate host - freshwater snails. Introductory chapters are focused on general introduction into the topic, such as basic terminology or occurrence issue of trematodes (mainly schistosomes) in the world and in the Czech Republic. In order to determine larval stages of flukes and their morphological types, the research was conducted in four Prague localities with known presence of aquatic snails. Only in one site, Kunratická tůň Pond, the constant presence of echinostomous cercariae (and in lesser extent also furcocercariae) in Radix labiata was recorded during summer season of 2015. In small pond in the Botanical Garden of the Natural Sciences Faculty of Charles University and in Modřanské tůně Ponds, xiphidocercarie in Lymnaea stagnalis were found. No cercarie were detected in the pond in the Genetic garden of Charles University. The presence of Leucochloridium paradoxum in the European Amber Snail Succinea putris was confirmed in the vicinity of Modřanské tůně Ponds. The verified...

Vybrané aspekty vlivu bezobratlých herbivorů na složení travinného společenstva
HRUBÁ, Karolína
The first part of my thesis is focused on observation of the leaf damage by invertebrate herbivores during season. I examined how the selected traits affect the palatability of plant species. In the next project, I investigated the effect of herbivory and gaps on seedling establishment. And finally, in the last part, I studied the effect of herbivory of terrestrial gastropods on competitive relationships among selected species.

Life around the water and in the water, five environmental programs for kindergarten
KREJČOVÁ, Hana
Krejčová Hana 2014: Life around the water and in the water, five environmental programs for kindergarten. Bachelor thesis. Faculty of Education, University of South Bohemia in České Budějovice, 63 pp. My bachelor thesis contains practical elaboration of five environmental programs for kindergartens. Main theme is life of animal around the water and in the water. I have chosen these themes: "Snails", "Insects", "Fishes", "Frogs", "Lizards and Snakes." Bachelor thesis contains beside practical part also theoretical part focused on pedagogy and natural science. Theoretical part is way-out for practical elaboration of all activities included in the submitted programs. My bachelor thesis also contains a discussion about suitability of form and content of the suggested environmental programs according to experiences of kindergarten teachers. Respondents have been asked by on-line questionnaire.
