Utilization of unconventional biomass for energy production
Boumová, Markéta ; Kropáč, Jiří (referee) ; Pavlas, Martin (advisor)
Tato diplomová práce se zabývá netradičními druhy biomasy využitelnými v České republice a Španělsku a jejich srovnáním. V prvních kapitolách jsou popsány netradiční druhy biomasy, mezinárodní projekty, smlouvy a legislativa. V následujích kapitolách je rozbor netradičních druhů biomasy zejména vznikajících z potravinářského průmyslu každé země s detailním rozborem a srovnáním zbytků z průmyslového zpracování slunečnice a oliv. V závěru je uděláno celkové srovnání těchto druhů biomasy České republiky a Španělska z aspektů výkupních cen, výhřevností, vlhkosti a množství popelovin.

Building survey and evaluating the state of construction
Kolláriková, Simona ; Anton, Ondřej (referee) ; Heřmánková, Věra (advisor)
The diploma thesis deals with building survey of the New synagogue in Velké Meziříčí. It is focused on diagnostics of timber structures using non-destructive and semi-destructive testing methods, such as visual inspection, moisture content measurement, penetration depth of a steel pin measurement and endoscopy. The aim of the thesis is to evaluate the condition of the timber structures according to the results of the building survey.

Fuel properties: Determination of moisture solid fuels
Tretera, Michal ; Musilová, Petra (referee) ; Lisá, Hana (advisor)
This bachelor's thesis deals with the determination of moisture content in solid fuels. First part contains classification of solid fuels, proximate analysis of solid biofuels and a research of methods for determination of moisture content in solid biofuels. Description of impacts of the moisture content on fuel is included in the proximate analysis. Second part of the thesis is experimental. Thirteen solid biofuels and one solid recovered fuel were measured to obtain their moisture content. The methods used to determine the moisture content include four different drying methods and a xylene distillation method. For each method there are details of the procedure and a summary of the results.

Biokompozitní materiály v nábytkářství
Kopecká, Magdaléna
This bachelor thesis deals with the issue of using biomaterials as an alternative substitute for non-renewable materials and raw materials to ensure future ecological sustainability. The referential biocomposite chosen as an alternative to non-renewable materials was fungal mycelium. The basic properties of this biomaterial, the method of production, and the safety requirements are described in this thesis. Furthermore, selected tests of physical and mechanical properties were undertaken. There tests included moisture, density, swelling and determination of transverse tensile strength perpendicular to the plane of the board. All measurements were carried out in accordance with ČSN, the tests results were described and statistically verified.

Vliv tepelné a chemické modifikace na sorpční, difuzní a hygroexpazní vlastnosti dřeva
Imramovský, Pavel
This thesis dealed with the influence of heat and chemical modification on sorption, diffusion and hygroexpansion properties of wood. To this aim, a thermal modification of European beechwood was carried out at temperatures (180 °C, 200 °C, 220 °C) in the special modified chamber of Katres. Furthermore, chemical modification was required on individual samples using acetic acid anhydride. The individual samples had to be sliced in radial and tangential directions using microtoma. A dynamic vapour sorption (DVS) device was used to determine the sorption and diffuse properties of all these beech slices as well as the reference unmodified sample. In addition, dynamic swelling was determined for all groups studied in radial and tangential directions. In order to determine the rate of swelling, sample sizes were measured using a scaler in specified directions before and after the 24-hour period in the water. The results indicated that both heat- and chemically-treated beechwood scored better against moisture than reference untreated samples. The diffusion coefficient in the radial direction was also higher than in the tangential direction, which corresponds to the professional literature. The results indicate that heat- and chemically-treated beechwood resisted better moisture than the reference untreated samples. Within swelling, direction plays a large role, as measurements in the tangential direction are nearly twice as high as the radial. The possibilities of using modified wood in construction as well as from the perspective of the researched characteristic were considered. The statistics were performed in the ANOVA program.
