Geophysical survey of undermined area in Lukavice near Chrudim
Slavíčková, Michaela ; Blecha, Vratislav (advisor) ; Dohnal, Jiří (referee)
Lukavice village is located in Eastern Bohemia and it is known for its historical pyrite mining. The first mention of mining comes from the beginning of 17th century. The mines were abandoned in 1892 due to a significant depletion of the upper parts of the deposit and also because of the competition of cheaper pyrite from abroad. Old mine workings were often backfilled incompletely and their exact location is unknown. The occurrence of empty mine workings under the roads in the village centre could cause a collapse of the ground under the weight of heavy trucks which carry through Lukavice village aggregate from the nearby quarry. The aim of geophysics was to determine the thickness of dump material (seismics), subsidence monitoring in the village centre (repeated levelling) and the principal aim was to locate old mine galleries and shafts (gravity survey). Gravity measurements did not prove the presence of empty mine workings under the main road at the village centre. Most pronounced negative Bouguer anomaly, which occurs in the vicinity of Bartolomějská jáma schaft, may be caused by higher degree of alteration of underlying porphyroids. According to historical maps and photos we determined approximate location of the former water pit Vilemina. For the determination of the exact position of the...

The Personal Identity of Adolescents - Drug Usersafter Entering Therapy
Vaňková, Monika ; Šulová, Lenka (advisor) ; Miovský, Michal (referee) ; Boukalová, Hedvika (referee)
The aim of this thesis is to map the psychosocial characteristics of adolescents using drugs while subject to therapeutic intervention in connection with noticing changes in their identity. The theoretical part is divided into three chapters. The first chapter cites the characteristic signs of adolescence relating to biological, cognitive, emotional and psychosocial developmental changes. The content of the second chapter is the formation of identity as a key theme of adolescence. In the third chapter, dedicated to the specifics of drug using in adolescence, themes relating to the origins of addiction, the roles of psychosocial factors and rehabilitation possibilities are discussed. The empirical part presents the research, processed research data from Safety Line conversations on the theme of addiction, research data from questionnaires and conversations with 41 adolescent drug users who entered an educational-therapy stay in the Alternativa department, SVP Klíčov and research data from a case interpretation study. Key words: Adolescence -identity - drug use - therapy

Reconstruction and model of postglacial spread of subgenus Alnus in Europe
Jelenová, Hana ; Barták, Vojtěch (advisor) ; Mandák, Bohumil (referee)
Many paradoxes exist about postglacial tree migration and they dont solve for many European trees. One example is wetland trees subgenus Alnus, which spread across Europe during the last glacial very quickly according to fossil records. The aim of this thesis is detection their migration potential, with the help of empirical evaluation of interpolated pollen data (interpolation method IDW) and a simulation model based on environmental characteristics of the species. The results of interpolated maps are similar to the rate previously estimated speed and the results of simulation model achieve these speeds only by A. incana but with specific extreme environmental conditions. The mason of this may be adapting its seeds to anemochorii because the simulation model confirmed their good potential to spread by the wind. Results of model for A. glutinosa don´t confirm the ability to rapidly spread by the wind and the observed rate must have another explanation. Maybe rivers can explain the empirical spread rate. This suggests visualization of migration lines and river networks.
The model has also been disclosure of environmental properties that are related to migration potential. Within the parameterization of the model is demonstrated, that R0 of A. glutinosa is significantly better than A. incana. But main parameters of anemochory model are terminal velocity and generation time, which is shorter by the A. incana, and therefore is probably able to spread faster than A. glutinosa.

Perception of older adolescents
KRŠKOVÁ, Michaela
This thesis tries to show a view of current adolescents on older people. It focuses especially on attitudes and opinions which create an image of a senior in nowaday's society. The theoretical part which is divided into four chapters includes basic terms: these are widening general knowledge about discussed problematics. The most important terms appear in the first part - adolescence, old age and perception. They describe physical and psychical aspects and tendencies that are typical of both stages (relationship of an individual to himself or herself, adaptation to ageing, satisfaction in life and vitality in elderly). Attention is drawn to socialization process which allows larger integration of adolescents into social life. This area is strongly connected to the area of social relationships including both adolescents and seniors. Such relationships can be seen especially in families, among relatives, friends or peers and their intensity changes over time. Very important and highly debated topic is also discrimination of older people. This topic forms the final part of this thesis. The last chapter deals with meanings of children's drawing and follows units which form this meaning (colours, size of figure, quality of lines). This part also includes a research of perception of seniors which was made in the USA. The practical part shows seniors graphically pictured by students of the eighth classes. These pictures are completed by information obtained from questionaries. The conclusion compares results of both researches.

Physically-based Modeling and Simulation
Dvořák, Radim ; Racek, Stanislav (referee) ; Šujanský,, Milan (referee) ; Zbořil, František (advisor)
Disertační práce se zabývá modelováním znečištění ovzduší, jeho transportních a disperzních procesů ve spodní části atmosféry a zejména numerickými metodami, které slouží k řešení těchto modelů. Modelování znečištění ovzduší je velmi důležité pro předpověď kontaminace a pomáhá porozumět samotnému procesu a eliminaci následků. Hlavním tématem práce jsou metody pro řešení modelů popsaných parciálními diferenciálními rovnicemi, přesněji advekčně-difúzní rovnicí. Polovina práce je zaměřena na známou metodu přímek a je zde ukázáno, že tato metoda je vhodná k řešení určitých konkrétních problémů. Dále bylo navrženo a otestováno řešení paralelizace metody přímek, jež ukazuje, že metoda má velký potenciál pro akceleraci na současných grafických kartách a tím pádem i zvětšení přesnosti výpočtu. Druhá polovina práce se zabývá poměrně mladou metodou ELLAM a její aplikací pro řešení atmosférických advekčně-difúzních rovnic. Byla otestována konkrétní forma metody ELLAM společně s navrženými adaptacemi. Z výsledků je zřejmé, že v mnoha případech ELLAM překonává současné používané metody.

Secondary school polyhedrons with internet
Helm, Jan ; Hromadová, Jana (advisor) ; Šarounová, Alena (referee)
The thesis is destined mainly for high school teachers and students of descriptive geometry. Above all it deals with the intersection and the construction of pyramids and prisms in projections. Students can meet with these phenomena at high schools during lessons of descriptive geometry. The constructions of the intersections of figures are demonstrated on solved tasks. The tasks are processed in graphic programmes GeoGebra and Cabri 3D prospering from the following advantages and facilities of these programmes: a stepping of the construction, a contour accentuation or a secretion of auxiliary lines etc. Besides these solved tasks, there are also some unsolved tasks for practice at the ends of chapters. The introductory chapter contains definitions and characters of common polyhedrons and regular (Platonic) figures. The thesis consists of web sites, a printed version and an enclosed printed version in .pdf format.

The Renaissance Altar at Zbraslav. The Tree of Jesse - the Family Tree of Jesus Christ
Valentová, Klára ; Royt, Jan (advisor) ; Nespěšná Hamsíková, Magdaléna (referee)
Klara Valentova The Renaissance Altar in Zbraslav English abstract In the first half of 16. century an altar dedicated to St. James was ordered by the Cistercians for their monastery church of St. James.It was the first work of woodcarving in our country to show features of the Renaissance.This altar is very interesting both in terms of its realisation and of its iconographic meaning.It is made like a flat carving and the whole surface is covered with polychrome, gilding and silvering.It is 7 metres high and mobile.It consists of a predella and three altar extensions.The predella is crossed by an epistyle which supports the first altar extensions with four columns. On the two inner columns there is a square extension with another two columns and on it is the highest semi-circular extension.The main plan of this altar is a trunk, which shoots forth from the body of Jesse and grows up from below to the top, bearing the fruits of the line of David through the altar's architectural structure. On the altar there are eight Jewish kings, six from before the exile and two after the exile. The family tree culminates with Joseph and the Virgin and the whole altar with the throne of mercy, the four symbols of the evangelists, the child Jesus and the dove. In the centre of altar stands the Virgin in the guise of the...

Equipment used by the Army of the Czech Republic during radiation emergencies.
ANTOŠKIN, Sergej
This thesis deals with the possibility of support of the integrated rescue system with assigned Army detachments. The theoretical part summarizes the transformation of the Ministry of Defence which had a major impact on the extent of the assistance provided. All rescue battalions were canceled and three engineer battalions and two separate rescue companies were created. Two rescue battalions were transformed into light motorized battalions and forwarded to the subordination of the Fourth and Seventh Mechanized Brigade. Organizational components of the ACR allocate a number of specialized teams for support intervening IRS. These include teams for ground and aerial radiation survey and decontamination detachments of people and technology, as well as some others, such as rescue detachment, detachment of transport humanitarian aid, a subunit of the earthwork, a subunit of the blasting and demolition, and more. Conditions requiring deployment of detachment vary according to the type of the assistance requested. They are primarily intended deployment Permanent Standby Force as planned assistance on request. This is the detachments in the central alarm plan and in accordance with the Act on the IRS ACR is required to provide such assistance. In providing assistance in dealing with radiological emergencies, ACR is equipped with a large number of devices, equipment and technologies. These are mainly radiometers, personal and group dosimeters. In the decontamination means is a habitat for decontamination of people and habitat for decontamination techniques LINE-82nd. The purpose of this thesis was to analyze whether the equipment ACR is still up-to-date with the times and that will be sufficient in comparison with similar Fire Rescue equipment. In the event of a radiation emergency is important to minimize the harmful effects of ionizing radiation on the population and the affected people. The lower limit of measurement was elected as the main comparing of the parameters measuring devices. In the case of decontamination of the equipment, attention was focused on the capacity of decontaminated people and technology. Carried out research revealed that earmarked detachments are equipped with measuring devices of varying ages and abilities. Some devices have been created at the time of the risk of nuclear war. This corresponds to their durable construction and a relatively high threshold, which is insufficient for the conditions solving a radiation accident in peaceful state. In addition, some of these instruments provide information and the measured value in the old, disused units, which can cause transmission of misleading information. Other devices are, however, modern, ergonomic, highly sensitive at low dose rate values, providing real-time information on the clear LCD display. Unique capabilities of the ACR give the possibility of performing aerial radiation survey, which greatly helps to keep the overview and assessment of future developments spread of radioactivity in the environment. The equipment ACR is quite outdated in the area of decontamination technology. Again, it originated at the time of the risk of nuclear war. The priority was a simple construction and operation, the ability of decontamination of large numbers of affected persons and equipment. However, there was practically no environmental solutions, separate showers for men and women and water consumption. On the other hand, the number of decontamination equipment of ACR virtually doubles the capacity of the firefighters equipment, which in terms of large accidental release of radioactive substances and decontaminated large number of people and technology is a distinct advantage. Overall, the Army units are able to qualitatively and quantitatively support the affecting IRS components and thus contribute significantly to dealing with radiological emergencies of any kind.
