Einsatz von Mikroemulsionen zur Behandlung schwermetallkontaminierter und organisch belasteter Böden

Katzer, Silke 11 July 2009 (has links) (PDF)
Das entwickelte Verfahrenskonzept stellt eine abfallarme Sanierungsmethode zur simultanen Behandlung schwermetallkontaminierter und organisch belasteter Böden dar. Die vom Boden abgetrennten Schadstoffe - Schwermetalle und Organika - werden in den entsprechenden Phasen der Mikroemulsion solubilisiert. Die entwickelte Formulierung der Mikroemulsion ist dadurch charakterisiert, insbesondere polare Schadstoffe respektive Schwermetalle aus kontaminierten Bodenmaterialien zu extrahieren. Der Einsatz der entwickelten bikontinuierlichen Mikroemulsion bewirkt bereits im ersten Extraktionsschritt die nahezu vollständige Entfernung sowohl der Schwermetalle als auch der organischen Schadstoffe. Durch eine mehrstufige Extraktion ist es möglich, auch hochkontaminierte Materialien einschließlich der Feinkornfraktionen zu reinigen und somit die Menge des zu deponierenden Bodenmaterials deutlich zu reduzieren.

Galerie letecké techniky a tradic letectví na letišti Medlánky v Brně / Gallery aviation technology and traditions of aviation at the airport Medlánky in Brno

Sudolský, Filip January 2016 (has links)
The main subject of the diploma project was to create architecture study for new building of a Gallery for sport aircrafts and their traditions and other equipment that cooperate with this topic. The Gallery is designed in Brno´s Medlanky municipality and it is incorporated on current local sport airport. This project was preceded by studio project on the same area, which included reconstruction and development of this airport area. In this diploma project I was trying to continue with this development and establish a design which would react to my earlier design. The site has a sloped character and it separated from a dense city area. Starting point for the design was to gently touch the landscape and also trying to find certain references directly in the closest surrounding. From the views to surrounding was created the idea to preserve the horizontal lines and with a landscape and constructions demands was created the main idea to continue with the landscape over the spatial structure. The need to cover large-scale exhibit items like aircrafts and other items from this topic led to a starting point of my design. The structure is formed as a spatial truss structure and dominates the exhibition space. Building is connected by program and structure to services and other areas like conference hall, coffee, study room, work room and administration. As a one building it teems mainly from arrival at the airport area when the roofing is an organic, monolithic surface disappearing in surrounding. But gallery itself emerges from the ground and opens towards the aircraft take off and departure area where it is also direction of a main view to the surrounding. The building is also unique for its entering, such as the main entrance through narrow staircase gap in the roof. This entrance should evoke to people an aircraft landing, where while descent plane dive in to the clouds and appear underneath above a whole new landscape. Thus a person sore in to the roof surface a

Organická soudobá architektura a bydlení / Organic architecture and contemporary residential living

Čábelková Nahorniaková, Marcela January 2012 (has links)
Organic architecture is often used term especially in connection with the daring and experimental form. The exact definition or division is still missing. The founder of modern organic architecture is to be generally considered as Frank Loyd Wright. He was the man who created organic architecture and also made first definition in the early twentieth century, when formulating new architectural styles. Dissertation deals with insufficiently described problem of organic architecture. The main focus is on contemporary production of residential organic architecture in Central Europe. Especially on the particular realizations in Hungary, Czech Republic, Slovak Republic, Austria, Germany and Poland. Beside detail description of European realizations, the dissertation deals also with foundations of organic architecture in U.S.A. and important realizations here. Modern organic architecture primarily originated in the United States of America. The work presents most important contemporary realizations and architects creating resident living organic architecture in other countries around the world in order to complete the overview. The objective of dissertation was describing newest trends in designing buildings for living. Find position of organic architecture and give reasons for it´s increasing popularity, spread and necessity for new development in architecture according to the new trends. Organic architecture is an alternative way of contemporary residential living. It´s popularity is growing in last years in response to the development of modern technologies and materials, the need to protect our natural resources and also to the increasing negatives of globalization and to denial of local traditions and regional specificities. Aspects of organic forms were divided into three main groups according to their main characteristics: form, harmony and sustainable development. Another objective was find location of contemporary organic residential architecture in Czech Republic and abroad. It is rather spread all over the world than concentrated on certain places. Therefore I selected countries that are richer than the others on the occurrence of organic buildings. The objective was also to address architects, specialists, public and especially university teachers of architecture and students themselves. Communication with them was mainly connected with grant project in 2010. The theme of grant project was contemporary organic architecture in residential living. There were lectures about contemporary organic architecture and exhibition on the theme: Contemporary living organic architecture. The publication of the catalog was published under the title: Contemporary organic houses - Europe. I had the opportunity to visit a number of organic family houses abroad. Specifically houses in Slovakia, Hungary and Germany. Results of survey, which was realized by questions to owners and authors of chosen buildings, are included in dissertation. The mail results of dissertation are - make a detail review of organic architecture in residential living - define trends in contemporary organic architecture and residential living - obtain and process answers from owners and authors of chosen buildings within survey - analysis of organic house ( houses) in city planning and landscape - publication of catalogue focused on organic contemporary European houses - article about contemporary organic architecture and residential living will be published in 2012 on archiweb page
