This thesis deals with widespread, chemically-themed misinformation. The the- oretical part describes psychological effects leading to myth spreading. It also descri- bes the debunking possibilities of such myths and the didactic reasons for misinformation- based work on the high school level. General practical part uses methods of content analysis upon random sample of School educational programmes to prove the usability of misinformation-based work in education. It also summarizes the organisations and resources useful for myth debunking. Specific practical part deals with analysis of chosen suspicious information, their credibility and the possibilities of educational work based on them. The chosen in- formation was the "medicinal" usage of chlorine dioxide solution. Rumors of alkaline diet and alleged harmfulness of aspartame, an artificial sweetener, were also chosen. The way they tend to be presented, none of these claims are backed. In all these cases, multiple unsubstantiated claims were found among proponents of these ideas.

This thesis presents a summary of published data on forest fires and which during these fires are likely to arise and endanger human lives, especially professional firefighters. It also contains general information on fires and forests, but there are also listed the most common causes of this type of fire. It also deals with the knowledge of the public, both professional and lay, of substances generated during forest fires.

The object of the diploma thesis is to analyse the environmental taxation in the OECD countries, to inform the readers about the development of environmental taxes and current trends in tax revenues from environmental taxes. The thesis is also focused on the structure of revenues from environmental taxes, the significant part is created by energy taxes, especially by taxes on motor fuels. Attention is also paid to taxation of carbon dioxide, according to the OECD the carbon taxes are one of the effective tools to reduce CO2 emissions, which is important to achieve the targets set under the Kyoto Protocol. The explicit carbon taxes are applied in the 12 tax systems of 12 OECD member countries and in the Canadian province of British Columbia. An increase of the countries applying carbon taxes since 2010 demonstrates the increased demand for this tool in recent years. The object of the last part of the thesis is to analyse whether declining tax burden on labour while increasing tax burden on energy is put into practice.

This thesis is focused in calculation and designing of fluid bed boiler for burning coal and wood biomass in the form of wood chips. The uniqueness of fluidized bed boiler is circulating fluidized layer and cyclone ash separator from flue gases beyond the combustion chamber.Work was divided into several parts due to different parameters of the fuel.. Stoichiometry calculations, emissions calculations, enthalpy of combustion and flue gas desulphurization calculations are performed in various parts.Further, calculating of the losses of boiler and its efficiency comparing to the calculation and design of each heat transfer surfaces was also solved so that resulting size and quantity meet the required specifications.Drawn set of this designed boiler based on calculations is included in the annex to this paper.

The main aim of this thesis was to optimalise composition of the titanium dioxide with a silica binder deposited on a PET foil. Emphasis was put on achieving maximum possible adhesion and hardness of the layer and the effect on photocatalytic activity. For the evaluation of photocatalytic activity comparative experiments with prepared layers were performed. Benzoic acid, dimethyl sulfoxide and azo dye Acid Orange 7 were used as model pollutants. Photocatalytic activity was investigated using UV-VIS spectrophotometry, formal rate constants and degree of conversion were also determined. The study results can be used for removing water pollutants from the water solution.

The thesis deals with the study of magnesium oxide burned by various burning regimes and his possibilities of its usage as potential expansion additive. The theoretical part of the thesis concerns mainly the volume changes and how they can be influenced. The practical part focuses on monitoring morphology, phase composition and the hydration process of magnesium oxide.

Tato práce je zaměřena na návrh terénní bezdrátové senzorové sítě pro mikroklimatologická měření, zejména výronů juvenilního oxidu uhličitho v oblasti hydrotermílního krasu, založené na LoRaWAN. V teoretické části práce je předložen přehled cílové oblasti, možností řešení měření, získávání a přenosu dat. Praktická část se pak věnuje kompletnímu návrhu celého systému, to znamená od měřicího zařízení přes koncentrátor a gateway až po backend odesílání dat do cloudového úložiště. Výsledky tohoto komplexního problému jsou prezentovány průběžně a přílohy obsahují detailnější a názornější ukázky.

This diploma thesis deals with matte coatings for 3D scanning purposes. The coatings are made with spray gun which uses a vibrating membrane atomizer and air blow gun. A suspension of titanium dioxide and alcohol is used as a coating material. This thesis describes the effect of the spray gun process parameters on the deposited coatings. These include, for example type of the coating suspension or setup of the blow gun. Phase Doppler Anemometry was used to measure spray characteristics. Deposited coatings were measured with profilometer and scanned with 3D scanner to study their thickness and effect on the results of 3D reconstruction. The result of this work was the coating with thickness below 1 µm with good optical properties for 3D scanning purposes. Standard deviation of the captured point cloud from the reference plane was below 0.0011 mm.

Metapovrchy sú nanoštruktúrované povrchy vytvorené za účelom špecifického ovládania propagácie svetla. Predstavujú revolúciu v oblastiach ultratenkých optických prvkov a nanofotonických obvodov. Zakomponovaním laditeľných dielektrických materiálov do metapovrchov sa otvára možnosť aktívne ovládať ich optické vlastnosti aj po tom, čo boli vyrobené. Oxid vanadičitý (VO2) takéto ladenie umožňuje vďaka svojej fázovej premene už pri teplote okolo 67°C a preto sa radí k najsľubnejším z laditeľných dielektrických materiálov. Nakoľko je možné postupnú fázovú premenu vo VO2 vybudiť opticky a lúč svetla je možné fokusovať do stopy s veľkosťou pár stoviek nanometrov, laditeľné metapovrchy obsahujúce VO2 by mohli byť ladené postupne a dokonca s nanometrovým rozlíšením. V tejto práci skúmame fázu a amplitúdu svetla po prechode VO2 nanoštruktúrami usporiadanými do metapovrchu navrhnutého pre viditeľnú zložku elektromagnetického žiarenia. Výskum fáze a amplitúdy je založený na numerických simuláciách VO2 nanoštruktúr (stavebných kameňov metapovrchov), ktoré sú následne overené experimentálnymi výsledkami. VO2 nanoštruktúry vykazujú taktiež Mieho dielektrické rezonancie, ktoré sú v závere tejto práce využité v postupne laditeľnom metapovrchu fungujúcom vo viditeľnej oblasti. Okrem termálneho ladenia je možné vyrobený metapovrch ovládať taktiež opticky, čo dokazuje možnosť postupného ladenia na nanometrových rozmeroch.

Project is target on design and realisation of device for control of central ventilation and air distribution. Control unit evaluates air quality in habitable rooms and assure automatic air change. System is driven by microprocessors and uses electronically controlled valves and ventilator regulation. Project is focused on evaluation of carbon dioxide concentration and detection of fire in rooms. Control unit cooperate and communicate via data bus with already designated control unit of hot water heating. Whole unit can be easing connected to the PC using ethernet.
