The topic of this thesis is dissection of vertebrate skeletons while using available and appropriate methods. The theoretical part is prepared based on Czech and foreign sources. For this part, there were used print publications, articles from journals and some Internet sources. It summarizes theoretical knowledge of the occurrence and anatomical structure of vertebrates. The practical part includes methodology involving collection, preservation and actual processing of animals. In detail, there are described possible methods of work that are evaluated and compared in the closing part. These proposed procedures are used for the selected representatives of vertebrates, in the individual chapter called - Results. The outcome of this thesis is a detailed guide with the procedures of chosen methods and preserved skeletons with a description of their characteristics. Powered by TCPDF (www.tcpdf.org)

The subject of this final thesis was to study the techniques used to extend the life of plants, in practice to test and evaluate them. The obtained material is used to design an arrangement for specific historical interiors of Znojmo castle. The third task was to measure the temperature and humidity in one of the rooms where the arrangememnt was placed. The thesis includes a supplement with photographs of plants preserved with various techniques and examples of period interiors with installed floral arrangaments.

Lipases have been widely applied in the manufacture of food products and in some areas of the industry, nowadays they are used in synthetic organic chemistry catalyzing the hydrolytic/esterification reactions under very mild conditions in the field of protecting groups or enantiomer resolution. In this study, the commercial lipase from bacterium Pseudomonas fluorescens was immobilized using the sol-gel process into organosilicate materials with propyl, octyl or phenyl substituents. The highest hydrolytic activity was found in the enzyme on the octyl-derived carrier. The immobilized enzymes differ in their hydrolytic activities on 4-nitrophenyl esters of various lengths. Subsequent experiments revealed quite good pH stability of the enzymes in a buffer (incubations in pH 3 through pH 11), as well as good temperature stability in isooctane (incubations at up to 100 řC). The majority of organic solvents seem to have no substantial effect on the lipase activity. The biocatalytic properties were studied on a model compound from the group of the acyclic nucleoside analogues - 9-(2',3'-dihydroxypropyl)adenine (DHPA). It was found for example that the best acyl donors are vinyl esters, that the lipase shows a preference towards longer vinyl esters, that the reaction proceeds faster in non-polar solvents or that it...

TITLE: Manufacturing taxidermy mounts and their use as teaching aids AUTHOR: Jana Mazalová DEPARTMENT: Department of Biology and Environmental Studies SUPERVISOR: RNDr. Jan Řezníček PhD. ABSTRAKT: The main subject of this thesis is focused on preparation of taxidermal mounts with use of mammal bones and skins and their use as teaching aids. The target group are school children both of elementary and secondary schools. The thesis describes methods of bone preservation and cleaning, skin tanning and preparation of taxidermal mounts. I deal in it also with preparation of large vertebrates' skulls and preparation of taxidermal mounts. The procedures are described in details and the following chapters include photos of dissections made by me. Preparation of 4 bird and 6 mammal species is described. For each description, search of recent literature and PowerPoint presentation is included. KEYWORDS: preparation, taxidermal mounts, skin, vertebrates' skulls

This diploma thesis deals with common parasites of game animals, animals and human occurring in the territory of the Czech Republic. It focuses on their fixation and general preparation of such specimens for usage in teaching of Science. The first part is devoted to the phenomenon of parasitism, and the history and definition of this concept. Systematic hierarchy of various unrelated parasitic groups is clarified. The second part provides the list of parasites, from the evolutionary original to the highly derived groups. We give an overview of their morphology and anatomy with the emphasis on their life cycle. The detailed knowledge of life cycle is essential for obtaining specimens. In each group, we indicate methods of collection and fixation in detail. The co called smartmicroscope represent the main point of the third part of proposed diploma thesis. Text of the thesis is supplemented with pictures taken by smart microscope, as well as by common microscope. KEY WORDS parasite, parasitism, mikropredatore, vector, fixation, preparation, smart mikroscope

The thesis briefly describes some techniques of preparation which should lead to creating ornithological dermoplastic preparations and their use in education and biology. These techniques are shown on several bird species. The thesis can be also used as a instruction for creating ornithological dermoplastic bird preparations. It shows some problems of preparation technice. The main goal of the thesis is creating a real ornithological preparations which are, used for education on Pedagogical Faculty of Charles University in Prague. Key words: teaching practices, preparation, taxidermy, birds, ornithological preparation

This final thesis represents a complete guide to making didactic aids which can be used in teaching Biology in primary and secondary schools. It completes my bachelor thesis on the topic of the Taxidermy of selected species of birds with detailed photographs of individual steps made throughout the creation process of a dermoplastic mount. It also compares the creation of bird mounts to those of mammal mounts, and it deals with making skeletons of vertebrates. This final thesis acquaints the reader with the taxidermic species, and includes research of foreign literature focussing on interesting facts about mounts. The final output of this thesis is a series of mounts and assembled skeletons of different species of vertebrates, which can all be used as didactic aids at the Department of Biology and Environmental Studies, Faculty of Education, Charles University. KEY WORDS taxidermy, skeletons, vertebrates, didactic aids, dermoplastic mount

1 ABSTRACT The thesis is conceived as detailed guide to create a dermoplastic models for teachers of natural history and biology. The first part focuses on the actual field of taxidermy and its methods. It includes some possible methods leading to the making of dermoplastic models of mammals, reptiles and fishes. The second part describes the created models of mammals, reptiles and fishes. This section also contains the characteristics of individual species and recent research from specialized foreign literature.

Er: YAG laser is a new method of preparation that promises gentler and more accurate dental treatment. Its specific characteristics is large absorption of the beam in the water and a small absorption in the tissue without the thermal effect. Therefore the treatment is safer and effectiver. The research has the aim in its theoretical - cognitive part to assess its advantages in comparison with treaditional treatment method - drill. As an essential element will be evaluation of caries lesion in vitro and in vivo. The size of the cavity will be judged on, the shape of developing a smear layer and retention surface in relation to the filling and the . The extracted teeth will be scanned in electronic microscope to assess the formation of contact and non-contact preparation, focusing on the shape and size of the prepared lesion in relation to modern filling materials - low viscosity composites. Extensive research supported by the Ministry of Health (IGA : 9991-4 and 13351-4) that focuses on the the use of various therapeutic methods in the treatment of special needs patients. Dental treatment of a special needs patients is expensive and time-consuming than conventional dental treatment. Therefore, clinical application of theoretical cognitive part will create a electronical support system for the...
