Drinking water treatment plant Koryčany - used technology and their changes from the actuation to nowadays
Konečná, Veronika ; Mergl, Václav (referee) ; Mega, Jaroslav (advisor)
Bachelor's thesis describes the problems of drinking water treatment with regard to specific technology used at Koryčany drinking water treatment plant which covers about 13 per cent of drinking water production in Hodonín district and supplies about 20 thousand people. Technology used at Koryčany drinking water treatment plant and their changes over the years of its existence (from 1959 when the original project was developed until nowadays) were depicted using archives and other available sources. The drinking water treatment plant was designed originally as four-stage (partial decarbonization, clarification, filtration, dechlorination). Decarbonization was left out before completion and dechlorination was skipped during reconstruction in 1971. Since then there were two more reconstructions (in 1991-1993 and 1998-1999) but the technology remained two-stage (clarification, filtration) so far.

Ecotoxicity of selected pesticides
Konečná, Veronika ; Vávrová, Milada (referee) ; Zlámalová Gargošová, Helena (advisor)
Presented diploma thesis is focused on the ecotoxicological evaluation of insecticide mixtures Perfekthion and Bulldock 25 EC and their effective substances, dimethoate and beta-cyfluthrin, respectively. Dimethoate is an organophosphate insecticide while beta-cyfluthrin belongs to pyrethroids. Both mixtures’ target organisms are sucking and biting pests on grain crops, potatoes, vegetables, oilseed rape and ornamental flowers. Their application over large areas and transport in large volumes generates a significant risk of entering the environment. Mixtures and substances were tested on water plant Lemna minor, algae Desmodesmus quadricauda and crustaceans Daphnia magna and Thamnocephalus platyurus. The LC50, EC50, and IC50 values were determined and ecotoxicity of substances and mixtures was evaluated and compared.

Evolutionary drivers and consequences of parallel evolution in plants
Konečná, Veronika
Parallel adaptation to similar environmental pressures provides ideal model systems to study the repeatability of evolution in nature. Such replicated natural experiments can also provide important insights into the genomic basis of adaptations. However, well-documented examples are rare, particularly in plants. Here, I brought new evidence of parallel evolution from three plant systems facing one of the most challenging selective environments - alpine stands and toxic serpentine soils. Further, I leveraged the cases of naturally replicated parallel adaptation in Arabidopsis arenosa to study the extent of phenotypic and genomic parallelism and to address the evolutionary sources of the parallel genetic underpinnings. By combining population genetic and experimental approaches I documented the complex interplay of adaptive, historical, and ecological processes in parallel evolution. The island-like distribution of high-elevation and serpentine habitats promoted their independent colonizations by distinct genetic lineages of A. arenosa and Primula elatior separately in each geographic region. Further, I showed how challenging environments structure genetic diversity within a species. For instance, I found higher genetic differentiation among (sub)alpine populations than among foothill populations....

The concept and types of bills of exchange and promissory notes
Konečná, Veronika ; Zahradníčková, Marie (advisor) ; Čech, Petr (referee)
The topic of my diploma thesis is "The Concept and Types of Bills of Exchange and Promissory Notes". The reason, why I chose this theme, is my interest in business law and in particular in the securities law. However, the main motivation which led me to analyze this legal sphere, were anteriorly my previous work experiences. From the plenty of cases I have had the opportunity to see, emerged for me a surprising conclusion, namely that the participants of the bill relationships are often not in a significant amount familiar with the essential content requirements of a bill of exchange as a security, which in the case concerned led to serious and thoroughly negative consequences. It is obvious that a bill of exchange represents for a general public not easily understandable problematic which requires precision and excellent knowledge of law. For this reason I have paid attention to the issue of essential appurtenances of a bill of exchange whose presence is demanded by law and without their remark a bill of exchange is fundamentally not valid document. The goal of this diploma thesis is to analyze and characterize a bill of exchange as a legal instrument and to define its basic attributes in a view of the fact that in the Bill of Exchange and Cheque Act, not even in other legal rules including...

The patterns of local adaptation to serpentine bedrock in plant populations
David, Jan ; Čertner, Martin (advisor) ; Konečná, Veronika (referee)
The most important abiotic factors of serpentine habitats are lack of water, low content of main nutrients, high magnesium content and a high concentration of heavy metals. Thus, serpentine soils are a very stressful environment for most plant. For their exceptional characteristics, serpentine sites are suitable for the study of evolutionary processes. The present literary review contains a summary of the main topics related to the issue of plant populations growing on serpentine bedrock. In addition, the mechanisms of the local adaptation and the conditions that allows these processes are analyzed. At the end of the thesis, the ecological aspect of the habitats is discussed, which can serve as areas with reduced competition and provide the living space to the competitively weaker species. Due to the specific conditions at the serpentine areas, these areas are characterized by a higher level of endemism and often serve as a refuge for relict species. Keywords: Serpentinophyte, serpentine, serpentine endemism, local adaptation, substratum specialization

Phenotypic variability and evolutionary relationships among populations of Primula elatior along an altitudinal gradient
Konečná, Veronika ; Kolář, Filip (advisor) ; Mandák, Bohumil (referee)
Primula elatior represents a promising model for addressing the role of phenotypic plasticity vs. genetic basis of traits in populations differentiated along altitudinal gradients. Phenotypic plasticity is mainly exhibited by the extensive variability of the leaves. Genetic structure of P. elatior populations has been poorly studied so far, the first insights suggested potentially large intraspecific genetic variation. Therefore, the first aim of this study was to reveal the genetic structure as well as morphological and cytological variation of P. elatior populations in the central Europe and compare those to another two intraspecific taxa from the southeastern Europe. Further, I selected three target mountain regions to address the role of altitudinal differentiation for structuring genetic diversity. Finally, I evaluated the status of the putative endemic species Primula elatior subsp. corcontica from the Krkonoše Mts. Microsatellite analyses, multivariate morphometrics and flow cytometry were employed to evaluate variation of P. elatior populations. I identified six major genetic groups by genotyping 12 nuclear microsatellite loci in the study area of central and southeastern Europe with the clear separation of subp. intricata. Focused on the central Europe, three well-defined genetic groups...

Knowledge of nurses about posibilities of using moist wound healing in neonatology.
Konečná, Veronika ; Kulhavá, Miluše (advisor) ; Novák, Ivan (referee)
This thesis deals with nursing care of skin defects using a wet therapy in neonatology. The first section summarizes information related to preterm infants, the development of the individual layers of the skin in the embryonic period. It lists the types of skin defects which the neonatolgy nurse may frequently encounter at the department with including a list of modern therapeutic coverage that can be used. It lists a brief history of wound healing too, focusing just on the development of the wet therapy . Furthermore is marginally discussed the evaluation and documentation of damage to the skin wound. For interest, the thesis mentions a case reportof the preterm newborn with the necrosis of the lower limb, accompanied by commentaries of the alternative treatment for this type of skin damage from my own experience. The second part is assessing the awareness of the nurses in the modern methods of the healing. The priority is the mapping of the experience in using the wet therapy through the quantitative research, which is mediated by an anonymous questionnaire. The main goal of the research is to determine the awareness of the nurses from the neonatology intensive care unit, resuscitation and intermediate care in the nursing of the skin defects using a wet therapy. For this purpose the chosen method...

Endemic plants of the Sudeten Mts., with emphasis on the taxonomically controversial Primula elatior subsp. corcontica
Konečná, Veronika ; Suda, Jan (advisor) ; Knotek, Adam (referee)
The endemic species of the Czech Republic still present a hot topic. Effective research of this topic means understanding of factors which create and influence endemism. With the exception of the Alps and the Carpathians, endemics are relatively very rare in Central Europe. In the Czech Republic they are concentrated mainly in subalpine (alpine) areas in the High Sudetes. Majority of the Czech endemics is of relatively recent origin. They have not well differentiated yet and so it is difficult to taxonomically evaluate them. Endemics of the High Sudetes have probably originated in Holocene with the exception of apomicts, e.g. species of genus Hieracium, which have likely originated even earlier. The origin of most of the Sudetes endemics was possible due to geographic isolation of small populations called peripatric speciation. Peripatric speciation is probably responsible for the origin of taxonomically uncertain endemic species Primula elatior subsp. corcontica, which is a subspecies of highly variable P. elatior. In the Czech Republic occur three subspecies of P. elatior - subsp. corcontica, subsp. elatior and subsp. tatrensis. These subspecies are differentiated in the morphology of leaves and in their distribution. The description of P. elatior subsp. corcontica was based on morphological...
