Vliv klimatických podmínek na pevnost lepených spojů MDF
Boštík, Vít
This bachelor thesis deals with the influence of the climatic conditions on bonding strength of MDF. Three types of bonded joints were used for testing – MDF-MDF, MDF-oak and MDF-artificial stone. The specimens were glued together with two component polyvinyl acetate adhesive. One half of testing joints was exposed to higher temperature and humidity, the second half of testing joints was exposed to normal conditions. After conditioning the specimens were subjected shear tension test. Then it was compared strength of bonded joints between normal conditions and higher temperature and humidity conditions.

Posouzení vlivu podmínek skladováni loupané dýhy na její vlhkost v závodě ALFA Solnice
Borek, Ondřej
The purpose of this bachelor thesis is to assess the influence of the conditions of veneer storage in technological processes which are mainly dependent on the humidity of the peeled veneer. These are in particular the technological parts behind the peeling machine and the drying room from which the peeled veneer is transported to the warehouse. Determination of the moisture of the peeled veneer was carried out by the weighting method. Thanks to the moisture results it was judged how moisture was variable before the drying process which is then reflected on the dried veneers that are transported to the warehouse. Conclusion is how to modify the sorting and storage of peeled veneers in the production process so that the moisture content of peeled veneers is as balanced as possible during storage.

Návrh dřevěné fasády na rodinný dům
Trdá, Michaela
This work deals with design of wooden facade for a family house. In theoretictal part of work focuses primarily on diagnostics of problematice current wooden facades systems. Gradually is explained which kinds of wood are appropriate or inaproppriate for installation to exteriers what are essential rules in the realization of the facade and which way you can protect wood from external atmospheric influences. Theoretical section also includes design of three wooden facades of different trees. Practical part deals with designing and implementation of one wooden facade of the proposals. Drawing Documentation and justification why this type of facade was chosen are attached.

Proces sušení řeziva importovaného z tropických oblastí v teplovzdušné komorové sušárně
Skovajsa, Michal
The bachelor thesis follows and describes the drying process of tropical lumber in the company Weekamp Doors s.r.o., which is one of the major manufacturer of these woods in the territory of the Czech Republic. In the selected the chose drying batches of the tropical woods there is observed the drying process and the resulting quality of the dried lumber is assessed according to the generally applicable standards. Based on the information collected during the observation of the drying process was subsequently suggested possibilities of optimization of this proces.

Pevnostní vlastnosti lepidlových filmů v závislosti na klimatických podmínkách lepených spojů
Knápková, Adéla
The diploma thesis deals with influence of climatic conditions on the strength properties of adhesive bonded joints of outdoor wood furniture by using dispersion-based PVAc adhesive for assembly joints. Samples of acacia, beech and larch wood were glued with waterborne polyvinyl acetate adhesive. The glued joints were exposed to various humidity and temperature conditions in order to monitor the influence of climatic conditions on the shear tensile strength of adhesive film of individual wood species.

Možnosti rozvoje komunitního kompostování ve svozové oblasti města Lanškrouna
Šebrle, Jiří
The aim of this work was to analyze the current collection and disposal system of biowaste in the collection area of the town of Lanškroun and to propose an alternative in the form of community composting, which would be directed by Technical services Lanskroun. After the basic analysis, a community composting plant was designed, including description of all the actions needed for its implementation.

Analýza provozních a ekonomických ukazatelů pásové sušárny zemědělských komodit
Tichý, Michal
The thesis is focused on an analysis of operational and the economic indicators of belt dryer for agricultural commodities and factors which influence these indicators. In company Agros Haná s.r.o. had measured three consecutive dryings of corn for gains on a dryer line (years 2016, 2017, 2018). On the basis of the measured values were established the energy consuptions and the operating costs of a dryer for each of the years. In additional, the individual factors influencing the amount of drying costs were analysed. The humidity of the corn during harvest proved to be one of the main factors, the temperature of drying dependant on the ambient air temperature was determined to be another decisive factor.

Půdní semenná banka lužních lesů Jižní Moravy
Posslová, Jana
This dissertation thesis is dealing with the soil seed bank structure and composition in the flood forests on South Moravia, forest district Valtice. 97 soil samples was taken in 2011 and species composition was evaluated. Data were evaluated by appropriate statistical methods usány programs R, Turboweg and QGis. It was found that the species richness and the seed density is decreasing with the increasing age of the forest stand. Also the ratio of stress tollerant and ruderal species is changing. The soil seed bank is dominated mostly by Urtica dioica.

Preparation and Realization of Technical Survey of the Building
Brothánek, Jan ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
This thesis covers structural-technic research of family house situated in Brno. In the first part of thesis I discuss theoretical explanation of structures situated in the object and its assessment in vterms of structural engineering research. Goal of this research is to estimate strength of masonry. These properties are calculated in practical part of this thesis. Last part of thesis summarizes previous calculations of strength of masonry.
