Dendrochronologické datování a stavebněhistorické hodnocení krovu kostela svatého Jakuba Staršího v Omicích (okres Brno-venkov)
Tetur, Vladan
The aim of this work is determination of the age of roof construction of the Roman Catholic church of St. Jacob the Elder in Omics, using dendrochronological analysis. In this work is describes a standard procedure for dendrochronological dating from the sampling, editing, measurement and dating. There is also incorporated building-historical development of the building, where the effort is to determine chronologically the development of the whole building from historical literary sources. The roof of the church is mainly built of fir wood, except for two old oak binding beams, and binding beam belfry which is spruce. The fir trees used on the roof over the presbytery were cut away in autumn or winter in 1874 or in winter at the beginning of 1875. The oak trees used on the old binding beams were cut away after 1765. The fir trees above the main ship were cut away after 1917. The spruce tree used for the binding beam of the belfry was cut away in the autumn or winter of 1927 or in the winter of early 1928. Trees used for the bell tower failed to date. Using dendrochronological dating and anatomical wood building analysis, we were able to supplement or refine the historical development of the church.

Rekonstrukce přípravných porostů břízy bělokoré podsadbami
Souchová, Jana
The aim of the Dissertation Thesis was to assess the oak and fir tree seedling growth rate in the Deštná-Horákova Lhota, Bystřice nad Pernštejnem and Opatovec - Kukle areas. Measurements took place on 22 areas with various intensity release preliminary growth. The following parameters were measured: current height of the above-ground tree plant parts and its height in previous year, yearly growth rate, length of sideways growing tree parts, width of tree crown, height of dual and triple tree trunk parts, deflection of trunk from its vertical axis, width and length of leaf or needle, root neck diameter, multiple tree trunk, straightness of the trunk, multiple tree top, vitality of the plant, damages through animal bites or horn scrapings. It can be concluded that each variation results in different growth rate of the undergrowth. It has been found that the best growth rate under birch tree plants was achieved in a narrow strip of bare of the tree plant beds. The worst growth rate, on the other hand, was observed in the 0.5 tree trunk variation.

Dendrochronologické datování a stavebněhistorické hodnocení krovu kostela sv. Jakuba ve Staré Vsi u Bílovce (okres Nový Jičín)
Sochová, Irena
The aim of the thesis was to make a constructional-historical research and dendrochronological dating of the roof frame (truss) of St. James´s church in Stará Ves near Bílovce (the district of Novy Jicin). It is the case of the roof frame structure of hammerbeam type which was made from fir timber. The result of the dendrochronological analysis has shown that the trees used for the construction of the roof of the nave were fell down between 1712 and 1713. The trees used for the construction of the roof over the chancel were also fell down between 1712 and 1713. The oak bell stool could not be reliably dendrochronologically dated. The results of the dendrochronological analysis correspond to the historical development of the church found out from the literary and historical sources

Dendrochronologické datování a stavebněhistorické hodnocení krovu kostela Nalezení sv. Kříže ve Staříči (okres Frýdek-Místek)
Limberg, Tomáš
The purpose of this bachelor work was historical exploration of church of Founded st. Cross in Staříč (district Frýdek-Místek) and determine type of used wooden, roof construction. At first phase was looking for profesional litarature, dealing with problematics of roof construction and history of roof construction and looking for historical information about begining of church. Dating roof was solved by dendrochology. Next phase was knowing used wood (anatomical analysis) all the samples was removed by pressler drill. After that was known fir, as used element in construction and oak, used for construction wooden stool. Fir was cut in (1772 and 1773), corently in fall or winter 1772, or in winter 1773 when this year start. Oak was cut down in (1771 and 1772), corently in fall or winter 1772, or in winter 1773 when this year start. It was 18th. century, so type of construction in this age was hambálková soustava. After comparing this informations with literature, we got result , that hambálek´s roof systém was used as roof construction for this church.Formula clause:Prohlašuji, že jsem práci: Dendrochronologické datování a stavebněhistorické hodnocení krovu kostela Nalezení sv.

Povrchová úprava starého dřeva
Gerža, Pavel
This bachelor thesis deals with the issue of suitable surface treatment on the surface of degraded wood by atmospheric corrosion for indoor use. In this thesis three types of paint are compared. The paints are nitrocellulose coating, water-borne coating and two-component polyurethane paint. Surface treatments are evaluated for physical and mechanical properties of the surface. The physical and mechanical properties of the degraded surface are compared with the surface of fresh spruce wood prior to the application of paints and after the application of paints. This bachelor thesis also explains the issue of atmospheric degradation of wood and properties of degraded surface.

Dendrochronologické datování a stavebněhistorické hodnocení krovu zámku v Miloticích (okres Hodonín)
Foltýn, Pavel
The subject of this thesis is the construction and historic evaluation of the age of the wooden truss structure of the State Chateau Milotice in district Hodonín using dendrochronological analysis. There are used procedures of the dendrochronological dating that is procedure of sampling the samples, their subsequent processing and dating. The work also includes construction and historical description of the building, to which have been used available documents form the Moravian Museum in Brno. Fir trees used for construction of truss were originated from the end of year 1721 or from the start of year 1722. From pine trunk was dated just one sample, which met the requirements of period after 1893. Beams of oak trunks were originated from two periods after year 1813 and after year 1943. Probably, fir elements of truss are original and the rest came from of following repairs. Dendrochronologically data analysis helped to specify the previously estimated history of the building, which has a big meaning in the planned reconstruction of the truss structure of the chateau.

Dendrochronologické datování a stavebně-historické hodnocení krovu kostela svatého Václava v Lukovanech (okres Brno-venkov)
Brázda, Ondřej
The object of this thesis is the dendrochronological analysis determinating the age of the wooden roof of the Roman Catholic church of St. Wenceslas in the village Lukovany in the district Brno - venkov. The thesis describes the standard dendrochronological process from sampling, its modifications and measuring up to the actual dating. In the text there can be found also constructional-historical development of the building. The chronological order of this development was created based on the literature review, field work and questionnaires. The trees used for truss were cut after 1810, the trees used for the bell tower after 1837. The dendrochronological dating and the analysis of the anatomical structure of wood helped to validate and to narrow some historical periods of the church. The results of this work can help managers and possible investors in the managing of the building, considered repairs and reconstructions.

Dendrochronologické datování a stavebně historické hodnocení krovu budovy LDF MENDELU v Brně
Stefek, Ondřej
On inquiry of LDF MENDELU in Brno the age of wooden roof truss of building B of LDF MENDELU in Cerne Pole was determined. At the same time the age of wooden roof truss of building A in the university s areal was determined. Moreover, a compilation architectural and historical development of the same constructions was done. Because of the dendrochronological analysis, it is possible to date wood of archaeological researches, historical buildings or roof truss. In this bachelor thesis, the standard dendrochronological process is described; from obtaining initial samples, through samples treatment, determining of the type of wooden elements using anatomical structure, measurements of samples until final dating. The basis of historical development was formed with the aid of historical sources and articles, where it was possible to find the beginning of foundation of Mendel university in Cerna Pole and early history of buildings A and B, when building A served as an institute for blind people. Results which were found shows that condition of both constructions is good. Afterwards, the results were compared with available literature. Despite the fact, that both of buildings were damaged during The Second World War, roof truss preserved.

Přirozená obnova jedle bělokoré v převodu na výběrný les na Školním lesním podniku Masarykův les Křtiny
Opravil, Lukáš
The thesis demonstrates the progress and life of the natural regeneration of fir, spruce and beech in selected stands in the conversion to selection forest in Klepačov at TFE Masaryk Forest Křtiny. In the form of inventory circles there was further evaluated stand structure of interest stands and the health condition of fir on the plots. On the plots were assessed height, number and age of the seedlings. To assessing the impact of wild animals on the natural regeneration there were used existing fences. To evaluate the effect of light conditions on the regeneration, the plots were placed to represent the different lighting conditions. Based on the statistically evaluated data then was found a negative impact of game growing up main species of natural regeneration. For seedling fir and spruce is best suited perfect canopy. For seedlings beech is best suited temporarily interrupted canopy. It was also suggested practical recommendations designed to promote growing up fir regeneration in the area.
