Evaluation of wood surface treatments by non-destructive methods
Plšek, Matěj ; Brožovský, Jiří (referee) ; Vaněrek, Jan (advisor)
This bachelor thesis will be describing the basic technologies of timber processing and macroscopic signs according to which the visual strength grading is performed. Imaging methods will be described to identify the roughness of wood surface. In the experimental part, the surface roughness parameters for various surface treatment methods will be determined and the dependence of the surface roughness on wetting and penetration depth of the adhesive will be monitored.
Podlepování historických textilií: Metodika projektu Ministerstva kultury ČR NAKI II „Vývoj metod podlepování historických textilií“
Krejčí, Jan ; Škrdlantová, Markéta ; Drábková, Klára ; Bureš Víchová, Jana
Metodika doporučuje a popisuje konkrétní metody podlepování vhodné pro konzervování-restaurování historických textilií, a to s využitím v současné době dostupných adheziv a podkladových materiálů. Doporučení jsou v práci podložena výsledky rozsáhlého výzkumu, který byl proveden na Ústavu chemické technologie restaurování památek na Vysoké škole chemicko-technologické v Praze.

Gluing of plaster casts
Zítková, Petra ; Ďoubal, Jakub ; Tišlová, Renata ; Kokstejnová, Aneta
The aim of the conservation procedure was to create a study which first focused on the evaluation of materials (traditionally used and modern) according to criteria corresponding to the requirements for contemporary conservation procedures. Based on the information and findings of the study, the procedure subsequently recommends the use of a suitable adhesive material and further presents several possibilities of solving the gluing procedures depending on the damage of the works representing the most frequently solved situations in the restoration of plaster casts. The methods and procedures are demonstrated on selected objects made of plaster from the collection of plaster casts by Stanislav Sucharda, where they were used and verified during their restoration.

Evaluation of biological seed treatment of different field crops
TICHÁ, Eva
The thesis is focused on biological seed treatment of selected field crops using adhesive in combination with entomopathogenic fungi Metarhizium anisopaliae and mycoparasitic fungi Trichoderma virens. Guar gum, xanthan gum and carboxymethylcellulose were chosen as the adhesive. Within the experiments in laboratory conditions, the percentage of kernels germination of spring barley, winter oilseed rape and a cucumber was evaluated after 24 hours and energy of germination and vitality during 2 5 days. The adhesive in combination with the filamentous fungi had positive influence on growth and development of embryonic roots of spring barley and growth and development of seedlings in all tested crops. The evaluation of plant emergence took place under laboratory and field conditions and the plants were biologically treated. Furthermore, the ability to colonize environment of the entomopathogenic fungus M. anisopliae was verified in this thesis. The fungus was injected into the substrate using seed dressings. According to the results, the introduced fungus is able to infect larvae Tenebrio molitor and Galleria mellonella after specific time.
