Title of the diploma´s thesis: Habitat characteristics weevils in beech and spruce forest ecosystems Moravian-Silesian Beskydy In forest ecosystems Moravskoslezské Beskydy was conducted from 2007 to 2015 collection epigeic fauna using ground traps. Trapping took place at 6-week inter-vals from May to October. Family (Curculionidae) was evaluated in beech spruce stands using faunistic index in relation to the basic typological units which are forest vegetation zones (LVS), edaphic category (EK), forest type (SLT) and ecotope conditions such as soil type, soil chemistry, humus form and composition of the herb layer. Incidence was compared of Curculionidae in selected nature reserves in silviculture stands. Total were captured 26,743 individuals of Curculionidae amount of 52 species. Eudominant species are Otiorhynchus carinatopunctatus, Plinthus tischeri, Otiorhynchus tenebricosus, Rhinomias forticornis and Strophosoma melanogrammum. In Beskydy they were captured rare species Barynotus moerens and Barypeithes mollicomus. It was found continuity of some species of Curculionidae on forest vegetation zones (LVS), edaphic categories (EK) and continuity some species of Curcilionidae on soil attribute.

The thesis describes the horizontal and vertical structure of two permanent research plots with the developmental stages of the tree layer of native beech stands in NPR Broumov in the area CHKO Broumov nature reserve in the Sudetenland. The horizontal structure of the tree layer is random and in the developmental stages of natural regeneration. The average number of individuals natural recovery is around 15 100 individuals per hectare.

This diploma thesis deals with issues of fine and ultrafine particles formation during thermal decomposition and combustion of biomass. An introduction is devoted to a utilization of biomass as fuel. A following part describes the gas products emerging generally during combustion process. A current emission and air pollution situation in the Czech Republic as well as the health impacts of solid pollutants on human are also mentioned. Within an experimental measurement three basic factors that have impact on fine particles formation during combustion of beech wood (i. e. oxygen content in combustion atmosphere, type of the sample and size of the sample) were thoroughly analyzed. Attention was paid to a progress of thermal decomposition and combustion of sample with respect to the particles formation. Finally, a measurement of fine particles amount was accomplished in a real boiler successively with four different biomass pellet types.

This diploma thesis is focused on the influence of thermal modification on the strength of bonded joint in tension according to ČSN EN 205. For the purpose of this work was used beech wood. The thermal modification of the test samples was performed at temperatures of 160 °C, 180 °C and 200 °C. The selected bond strength adhesives were melamine-urea formaldehyde adhesives (MUF), phenol-resorcinol formaldehyde adhesives (PRF) and one-component polyurethane adhesives (PUR). In addition to the thermal modification the effect of plasma modification on bond strength is also determined. The test lamellas were plasma treated (DCSBD) prior to gluing and pressing. The result is the determination of the tensile strength of the bonded joint in all the above-mentioned modifications and comparation of the results.

of PhD Theses The Thesis is centred around the influence the Lazansky of Bukova aristocratic family had on the artistic environment in the Czech lands from the 16th to 20th century. On the background of their cultural-historical monograph, the author introduces the individual family member's construction and patronage activities, the development of their art collections and the wider context. Using the interdisciplinary research, the author con- fronts the results of his own work with the conclusions of previous researchers. He chal- lenges some of the earlier hypotheses for the Early Modern Age and draws from the untapped sources a wealth of information about the Lazansky family cultural activities in the modern history. He compares the resulting summary with the realizations of other aristocratic families in the Czech lands and in Central Europe. The author's efforts result is the first comprehensive view of the Lazansky of Bukova family in the wider context of cultural history, and in the rehabilitation of their role in artistic patronage. Keywords: Lazansky of Bukova, Marie Gabriela Lazansky, Prokop Lazansky, patronage, art collections, noble families, Manetin, Rabstejn nad Strelou, Chyse, Lubenec.

Lightweight chamotte products are popular building material. There are many types of lightweight chamotte on the market, but the most popular lightening options are organic ingredients. This brings some problems to the production of these products. This thesis deals with the burning of various types of lighters from shards of fireclay materials. In the theoretical part are summarized raw materials, which are necessary for production of lightweight chamotte. The results of the published research studies on the topic of lightening of organic lightening products are being described here. The practical part deals with properties of products made of clay or kaolin with the addition of a certain amount of lighter. These added lighters are spruce sawdust, beech sawdust, peat, bran, paper slurry and anthracite. All these lighters are direct. For comparison, the cenospheres, which represent indirect lightweights, were also included in the research. For all specimens, the temperature interval of burnout of specimens, refractoriness, classification temperature, bulk density, thermal conductivity coefficient and other properties were defined.
