Hodnocení vlivu prostředí na produkční parametry plantáží rychle rostoucích dřevin
Šťastný, Hubert
This thesis deals with the cultivation of fast growing trees, mainly the Japanese poplar, as the most widespread species cultivated in our territory. The first part of the thesis describes the history of fast growing timbers, followed by presentation of individual species of poplars. Furthermore, the individual methods of cultivation technologies are analyzed, from the selection of suitable habitat to the final reclamation of the plantation. The final part of the literary review describes the non-production functions of plantations, including possible negative impacts of growing fast growing timbers. The practical part of the thesis describes a private plantation of Japanese poplar clones located in the cadastral area of Žabčice. The measurements were made on a particular plantation. From the obtained data an estimate of the future plantation yield for individual clones was performed by power regression. The final part of the thesis discusses the data obtained mainly from the economic point of view.

Šťastný, Hubert
This thesis is focused on the evaluation of the influence of intentional solar panel cleaning on the production parameters. The basic theoretical information about solar energy, photovoltaic effect, division of the photovoltaic cells, solar power station equipment, the legislation and factors affecting the power of photovoltaic plant is described in the theoretical part. The practical part deals with the specific characteristics of the photovoltaic plant, its production parameters and technical equipment. The same, performance of the panels before and after cleaning is compared in this part. And finally, this part focuses on the benefits of cleaning for the plant and its production increase. Financial costs and the financial contribution to the owner of power station are discussed in the conclusion part.
