The effect of MDOC on testicular tissue II. Intratesticular application of a medicament with MDOC
Havlová, Martina ; Semecký, Vladimír (advisor) ; Herink, Josef (referee)
1 Abstract The aim of my rigorose work was to inspect and assess the effects of time and application of calcium/sodium salt of microdispersed oxidised cellulose (MDOC) to the structural components of testes, especially in the time after an operational localization of one testis into the intraabdominal cavity. We used a model of an experimental unilateral cryptorchidism in the adult male Wistar rats. The surgery was performed under standard conditions using a method introduced in the Department of Biological and Medical Sciences of the Faculty of Pharmacy Charles University. The rats were killed by overdosage of aether aenesthesia and the bilateral testes were removed. The tissues were immediately histologically processed. After the histological modifications we tained the sections with hematoxylin - eosin, green trichrome, Periodic acid Schiff and toluidin blue histological stainings. The evaluation was histological with optical microscope. We compared our results with studies, which are described in the theoretical introduction of my work. In the preparations from the time interval of 7 days after surgery with injection application of 1% solution of calcium/sodium salt of MDOC under the tunica albuginea we randomly measured the diameter of the seminiferous tubules. The diameter of the tubules that...

The posibilities of a landscape restoration after send mining
Vernerová, Marie ; Vacek, Oldřich (advisor) ; Havlová, Martina (referee)
This thesis deals with the possibilities of a reclamation after sand and gravel surface minig. It is based on our knowledge of the mining activities effects on the landscape and landscape character. The impacts of mining can be seen in all levels of the landscape structure. Minig activities affects geomorphic components of the landscape as well as a land use and landscape character. The most significant changes occure as a result of an extraction of send and gravel from the wather. As a reasult of mining huge lakes appear in those areas. This brings a change of landscape character and a land use. The second used method of surface mining is a dry extraction. The review of the reclamation possibilities in the Czech Republic is aso based on law in area of mining understanding. Studied literature divides reclamation techniques into two groups. The first group is composed of a traditional reclamation, which are agricultural, forest and hydric reclamation. The second group consists of ecological restoration tools - natural and managed succession and management tools.

Gladišová, Kateřina ; Vaněk, Jindřich (advisor) ; Havlová, Martina (referee)
The thesis is divided into several chapters, which continously follow one another. The introductory part is focused on the definition and the general characteristic of the territory of the Zlaté Hory. Subsequently it deals with the detailed history of the mining town and the surrounding area from 13th century, from when the first written mention of the town has survived, to this day. The thesis describes the gradual development of mining, the methods of mining the ore, the modern extraction and the total gold production. In the next chapter there are in short outlined the historical cultural monuments and their surroundings affected by mining. A separate part consists of the local gold washing area, which are divided according to the preserved mining relicts. The last chapters are focused on the general characteristics of the landscape memorial zones and the methodology for the creation of maps, which is the output of a literary review and includes the remains after the ore extraction and surface mining. In conclusion, the potential of the site in the context of landscape memorial zones reservation is scanned.
Part of the literary review, but also the whole of the thesis are my own photographs, which are trying to complement and to better navigate in the content of the entire work.

Comparison of economic and environmental aspects of waste management in selected municipalities of different sizes
HAVLOVÁ, Marie
The industrial development of our society pushes waste management into becoming an important part of both the economy as well as the environmental protection. It is essential to reduce the amount of waste which is being deposited in landfills without any further use. In the next 10 years it is necessary to completely eliminate waste disposal of the reusable waste and especially of the mixed municipal waste. This thesis focuses on the waste management of various types of municipalities. It aims to provide optimization of waste management, in the connection with economical and technical possibilities of various types of municipalities. This thesis is divided into two parts. The theoretical part describes the issue of waste management in the course of history. It shows the various methods of waste disposal and describes the economic and environmental aspects and impacts in general. It briefly summarizes the development of waste management legislation. The second part of this thesis is focused on the analysis of waste management in selected municipalities. Twelve towns in three groups of different sizes were chosen. A survey of waste disposal and the influence of the size of the town and its technical options on the waste management was conducted. The results showed that municipalities have substantial reserves in reducing the amount of waste going to landfill and also in the practical use of waste sorting. In the conclusion of this thesis suggestions to optimization of waste disposal are being presented.

Determination of mercury in selected foods
HAVLOVÁ, Michaela
The thesis resolves problems about the contain of mercury in chosen articles of food. Mercury, hydrargyrum, is a heavy metal, which is an important pollutant of environment. Mercury was determined for comparision in all in nine common articles of food. In rice, mushrooms, fish, lentils, poppy seeds, soya, soya dehydrated slice and oat flakes. Mushrooms were collected in four different provinces of Czech republic. In Highlands, Central province, South Bohemia and in province of Liberec. For comparings were analyzed cultivated mushrooms, Agaricus bisporus, from supermarket. As a fish were analyzed lyofilized samples of catfish, Silurus glanis. The other articles of food were bought in supermarkets. On an atomic absorption spectometer AMA 254 (Altec, Prague, CR), was made validation of analytic method. Results: accuracy (97%), precision (3,33%), sensitivity (0,00251 l/kg), limit of detection ((LOD= 0,31 ?g/l), limit of quantification (LOQ= 1,04 ?g/l), linear dynamic range (LDR= 1,04 až 100 ?g/l) and correlation coefficient of linear part of calibration (0,9979). Measurement of all samples was done with spectometer AMA 254. By analysis of all materials was detected that increased concentration of total mercury in all occures especially in mushrooms. The highest measured value, 5,7 mg/kg, was found in a mushroom Xerocomellus chrysenteron from South Bohemia. Measured concentrations at lyofilized fish weren't important, it was only 0,04 mg/kg. In other articles of food weren't detected overlimited values. We obtained from acquired results, that the highest amount of mercury is contained in our conditions in mushrooms. According to World Health Organisation is determined that the highest tolerable concentration for articles of food is 0,5 mg/kg of mercury. In mushrooms was found after recalculation as a top limit 0,57 mg/kg of mercury. So, this result is overlimited.

Obstacles to waste sorting of households in Southern Bohemia
HAVLOVÁ, Marie
Waste sorting and recycling has come to the fore in the last decades in all European countries. The main reason is a necessity to reduce the total amount of waste landfilled without further use. The aim of waste management is to reduce formation of waste and handling with waste for its maximum utilization as a raw material and minimal encroachment to environment. This bachelor's work deals the waste sorting of household and an obstacles in waste separation in households. The work is divided into two main parts. The first, theoretical part, contains a summary of information about the history of waste management and legislation from the European Union level to the regional and municipal planning of waste management and waste management of waste producers itself. The practical part of this work examines through a questionnaire survey the attitudes of the population to waste sorting and influences that may encourage waste sorting or conversely hinder from it. The results demonstrated that the majority of population understands the importance of waste separation and recycling. On the other hand, there is a scope for raising awareness about the usefulness of utilization of recycled materials. Therefore the conclusion summarizes some of the main issues and suggestions for promoting waste separation.
