The goal of this thesis is to examine a possible influence of the water soluble cores on the microstructure of commonly used aluminum alloys AlSi7Mg and AlSi10Mg in the lost wax technology. This thesis only deals with the changes of the eutecticum on the contact surface between the metal and the core and its surroundings where interactions can appear between the core based on the alkali salts NaCl and KCl and the alloy modified by sodium or strontium. The experimental part investigates the influence of the alkali salts on the modification additives and the modification of the structure itself.

Czech Republic is called roof of the Europe, several rivers rise here and many of them flow away and continue to other countries. That's why I find, that’s extremely important to manage out water sources properly and carefully, because for example the weather has a huge impact on our limited sources and can affect them especially in a dry periods. These issues can be improved by finding a use for used water, good storm water management as well as using greywater. In my diploma thesis, I'll be mainly focused on an overall water management in an ordinary family house. It has two parts as theoretical part and practical part. The theoretical part is then split into another three parts. The first part covers a storm water management, the second is about waste water management. The third explains greywater management. In practical part of my diploma thesis, there's my study of not disposing rain water into a drain with other waste water, but making both waters useful. In this my particular subject in village called Plesnice, is projected a waste water treatment plant. Treated water will be accumulate together with rain water. Accumulated water will be used for irrigation. For a waste water treatment is projected a constructed wetland with vertical flow (down flow reed beds) and facility for sludge management. This is example of extensive technology. Irrigation system consists of storage tank with mechanical pre-treatment and pump valve shaft, sprinklers for lawns, drip irrigation decorative surfaces and everything is controlled by a control unit. Thanks to irrigation and rainwater remains in effect, which is important for local microclimate and save drinking water. This study is an example of that in water management is not necessarily a need for global action, but you can start with individuals and individual houses, which in total could have a significant effect on water retention in the landscape and to slow down and reduce the peak flow in rivers.

This diploma thesis deals with sound water management and is divided into theoretical and practical part. The theoretical part is divided into three main chapters. The first part focuses on rainwater, its quality characteristics and utilization. The second chapter focuses on the management of waste water, its properties, the amount of waste water and natural ways of wastewater treatment. The last chapter is devoted to the gray waters and their utilization. The practical part focuses on the study of the draft comprehensive management of sewage and rainwater in the village Pařezov district Domažlice. It focuses on wastewater treatment using constructed wetlands, using rainwater for irrigation and infiltration of the remaining water.

A travers une exploration filmique menée auprès d'une communauté religieuse de Port-au-Prince, l’analyse des images enregistrées avec les personnes filmées et l’expérience pratique de constructions audiovisuelles participatives, la recherche interroge le système de représentation des adeptes et le rapport qu'il entretient avec la notion de croyance. Elle étudie simultanément par ce biais la réception de formes audiovisuelles spécifiques et l’observation différée des enregistrements en tant qu’outil privilégié d'une anthropologie audiovisuelle appliquée à l'étude des systèmes symboliques de représentation et à leur dynamique évolutive. Cette recherche est marquée par trois étapes de réalisations concrètes selon des paradigmes audiovisuels définis : un multimédia interactif, un film d’observation descriptif chronologique, et un film linéaire poursuivant l’objectif d’une mise en scène de l’autoreprésentation des agents suivant les précédentes étapes collaboratives d’observations, d’interprétations et de constructions audiovisuelles participatives qui forment l’enquête. L’image, sous ses multiples acceptions, est envisagée ici en tant qu’objet transactionnel agissant à différentes échelles sociales, depuis ses usages et fabrications à un niveau individuel jusqu’à ceux-ci à un niveau collectif et transnational. Cet aspect est analysé, d’abord, au moyen de la confrontation successive entre imagerie religieuse produite au sein de la confrérie et représentations audiovisuelles produites par la recherche elle-même et retournées aux agents, et ensuite, par confrontation avec l’iconographie religieuse et les représentations anciennes et contemporaines produites par des sources endogènes et exogènes à l’aire culturelle haïtienne. Le texte analyse ainsi la construction de représentations et leurs effets depuis les expériences pratiques menées avec les individus d’une communauté jusqu’à celles qui intègrent certains évènements sociohistoriques, certains clichés et certaines figures mythologiques d’inspirations vodou ayant intégrés la culture occidentale à travers, notamment, des représentations romanesques et hollywoodiennes ayant eu un fort succès et continuant à alimenter l’imaginaire occidental et haïtien aujourd’hui. / The Haitian voodoo presents a profusion of practices and perceptible representations, symbolic ones, as material as corporeal. He influences the arts and the literature of a whole culture, well beyond the circle of his followers. If it is plural from origin, it was also collected and represented in a multiple way by his outer observers. Forged during a tempestuous history and present, its representation system seems to present a character at the same time persistent and permeable, connected to the faith itself. Through the analysis of worship images, a cinematic exploration conducted within a religious community of Port-au-Prince, and finally through a participatory experience of confrontation of the recorded images with the agents and film construction according to three different modalities, the study attempts to question the representation system of the followers and the relationship which it maintains with the faith. The research also tries to examine restitutions forms and specific visual anthropology tools applied to the study of symbolic representation systems and their dynamics.

The work is devoted to the definition of rainwater by applicable legislation. Furthermore, it defines the term of restraint systems and infiltration of rainwater, with their brief description. Documenting the calculation of retention volumes for the three selected watersheds in combination accumulation, regulated runoff and infiltration. The work is processed simplified design documentation of accumulation of rainwater in the selected property. Thesis is complemented by photographs liquidation and use of rainwater.

Title: Model of training preparation for young future flyboarders Objectives: The objective of the work is to create a model of training preparation for young future flyboarders based on the empiricism of the most successful professional flyboarders. Methods: Ten intentionally selected respondents filled out the survey on their current sports specializations. Three of them were selected based on the frequency of specific and non-specific sports. Individual non- standardized interviews were conducted with them, which were based on direct verbal communication with the respondents. Results: We created a model of training preparation for young future flyboarders. The training preparation model is divided for children from six to nine years old, in which we recommend general sports training (gymnastics, athletics, swimming, sports games). For children from ten to twelve years old, we recommend trampoline jumping, high jumping, swimming, balance exercises, body strengthening and stretching. For children over the age of thirteen, we recommend starting to fly on a flyboard. Keywords: extreme sport, fly on water , water sport, training preparation, change of sport, adrenaline

The aim of the diploma thesis is to describe and prepare the pilot plan for drought and water scarcity for the selected locality, according to the prepared amendment of water law. Recent years have shown that drought will play a significant role in water supply in the future. Therefore, the need for tools to provide procedures and guidelines for individual administrations is more than important. The first part of the diploma thesis deals with issues of drought and water scarcity, climate change and prospects for the future. The next section describes a plan for drought and water scarcity. In the next parts of the diploma thesis, there are procedures that can mitigate or completely avoid the consequences of drought. From this informations, a pilot study of the plan for drought and water scarcity for the town of Počátky is being prepared in the next part.
