Vliv glyfosátu na fyziologické procesy v živočišném organismu
Jelínková, Lucie
This bachelor thesis deals with the effect of glyphosate on the animal organism. The influence of individual selected groups of animals and humans is examined in different types of expermients. The bees in the behavioral study showed a reduced response to sucrose, a deterioration in short-term memory and a deterioration in the formation of ofor-foos relationships. Glyphosate reduced biodiversity in the amphibian population and also halved the toxicity at lower doses when the active substance was studied. Glyphosate also affects carp hepatocytes, which are subject to histological changes. The deteriorating health of the fish, which is infested with exoparasites, makes it easier for glyphosate to enter the body. In rats and rabbits, they cause reproductive problems. Human placental cells respond to glyphosate by reducing the production of the enzyme responsible for estrogen synthesis and thus to fertility problems. Glyphosate is more common in professional exposure and i tis similar in the population living in the immediate vicinity of its application.

Development of children's communication skills with different Mother Tongues in pre-school education
Jelínková, Lucie ; Klenková, Jiřina (advisor) ; Korandová, Zuzana (referee)
This bachelor thesis focuses on analyzing methods of speech development skills of kids with different mother languages in preschool education. Main goal of this thesis is to get knowledge applicable in work with kids with different mother language and in developing their communication skills. Theoretical part is based on information from proffesional literature, current legislation and electronic information sources which desrcibe definitions of terms communication, speech and language, ontogenesis of child's speech till preschool age and specifics of bilingual child's speech development. In this thesis is also a describtion of Czech preschool education system and it is focused on a group of kids with different mother languages. The empiric part is processed in the form of qualitative research. The case study desrcibes development of communication skills of three kids with different mother language and the methods that are used.

Sexual incompatibility of protist cryptic species
Jelínková, Lucie ; Škaloud, Pavel (advisor) ; Urbánková, Pavla (referee)
The systematic and the evolutionary biology attempt to define a species category or a species taxon from the beginning of their existence. Specific taxons are considered species on the base of different criteria, so on the base of different species concepts. Most of these concepts emerged previous century. The biological species concept has been assumed to be most important species concept for dozens of times. It was based on a presence of the reproduction isolation of two species. However, its applicability was questioned by the existence of many asexual lineages and also the lineages with a large degree of hybridization between an approved species. This thesis is trying to give a description of the biological species concept and its changes during the time. And it is also trying to answer the question of its simultaneous usability for protist.

Analýza rozvoje krajů ČR
Jelínková, Lucie
The purpose of this master´s thesis is to assess the development of selected regions in Czech Republic between years 2010 and 2014. The development is assessed from economic, social and environmental perspective. In these areas the appropriate indicators of development (growth) are identified, which are assessed both individually and together. The introductory part is focused on theoretical overview of economic growth and development, measuring of economic growth, factors which affect the region level and the business environment within the specific region. Next part describes the method of construction of the composite indicator (KI). The thesis is based on selection and evaluation of the indicators with respect to their effect on the region development. It also provides possible recommendations. The proposed composite indicator is created by using the correlation matrix, appropriate method of data normalization, determining weights and aggregation. As a result of the work, there is a dimensionless quantity which establishes the order of selected regions within the given areas and the overall order, which is graphically visualized by cartogram.

Ecophysiological differentiation of Synura petersenii cryptic species (Synurophyceae)
Jelínková, Lucie ; Škaloud, Pavel (advisor) ; Elster, Josef (referee)
Synura petersenii represents a complex of pseudo-cryptic species. These are planktonic colonial organisms belonging to the class Chrysophyceae. The species are abundant in spring and autumn, when they produce golden-brown blooms in oligo-mesotrophic waters. In this thesis, I focused on investigating the effect of temperature to growth parameters of four selected species: S. petersenii, S. americana, S. glabra and S. conopea. Several temperature experiments were performed and statistically analyzed. According to growth curves the temperature 25 žC was mostly stressful for these organisms. Only S. petersenii sensu stricto was sometimes able to growth at this temperature. In general, the significant differences in growth rates were detected between S. petersenii and S. americana. In all experiments, S. petersenii had the lowest growth rate. This ubiquitous species probably acts as a K-strategist. S. americana grew generally very quickly, especially at temperature 13 žC that is obviously optimal for it. Further, I observed a significant strain specificity, which is largely a well-known phenomenon in the ecophysiology. Significant differences in growth rates were noted between temperatures 13 žC and 16 žC, where all tested species grew best, as well. This is in accordance with a general recognition of...

Management of the rain water in area
Jelínková, Lucie ; Synáčková, Marcela (advisor) ; Renata, Renata (referee)
There will be no life without water on Earth. Humans influence their surroundings more and more. There is less of drinking water every day. In a few years, absence of drinking water will be a big global problem. Therefore, we should learn how to manage with sources which we have. Especially, we should try to minimalize our influence on environment.
This thesis is focused on problems with rainwater in urban area. The first theoretical part of this work is devoted to legislation in the field and possibilities of using rainwater. The practical part includes design of management of rainwater in office complex in Prague. In this second part is several variants which could be realized on this location.
