Supported nanostructured Pd catalyst using atomic layer deposition: from methanol oxidation to hydrogen evolution reaction
Bawab, Bilal ; Knez, Mato (referee) ; Nielsch, Kornelius (referee) ; Macák, Jan (advisor)
V této práci byly zkoumány katalytické schopnosti druhů Pd deponovaných metodou Atomic Layer Deposition (ALD) na různých substrátech. Druhy Pd složené z nanočástic (NP) a jednotlivých atomů (SA) byly syntetizovány na vrstvách anodických nanotrubiček TiO2 (TNT) a uhlíkových papírech, aby se prozkoumalo jejich chování při elektrooxidaci methanolu a reakci vývoje alkalického vodíku (HER). Pd NP byly naneseny na vrstvy TNT jako katalyzátor oxidace methanolu, čímž se využil jejich velký povrch a přímý elektrický kontakt přes titanovou fólii. TEM analýza ukázala velikosti částic Pd mezi 7 a 12 nm, s posunem k tvorbě porézní vrstvy Pd po 450 cyklech ALD. Cyklická voltametrie odhalila, že katalytická aktivita dosáhla vrcholu po 400 a 450 cyklech, což ukazuje na optimální zatížení Pd a vlastnosti proti otravě, což potenciálně umožňuje přímou konverzi CH3OH na CO2. Další role Pd dosáhla přítomností SA a NP. Druhy Pd byly dekorovány na uhlíkových papírech a byly studovány jako HER katalyzátor. vzorky před a po elektrochemických měřeních byly charakterizovány rentgenovou fotoelektronovou spektroskopií potvrzující přítomnost druhů Pd2+. Elektrochemicky aktivní povrchová plocha se významně zvýšila s cykly ALD a dosáhla plató při 300c Pd. Pozoruhodné je, že CP 600c Pd vykazoval nadměrný potenciál 4,55 mV, což je nejnižší hodnota udávaná pro Pd elektrokatalyzátory v alkalických podmínkách. To zdůrazňuje synergické účinky Pd konfigurací na zesílení HER a zkoumá mechanismus, kterým dochází k HER procesu.

Detached House with Stable for Horses in Vysočina
Jaitnerová, Vendula ; Blažek, Petr (referee) ; Fišarová, Zuzana (advisor)
The aim of my bachelor´s thesis is the project of a family house and a horse stable. The building site is located on the outskirts of the village of Chlumek, in Czech-Moravian Highlands. The family house is designed for a family of four. There is no cellarge in the building, there is one floor and attic. There is a garage for one car located on the ground floor. In the northern part of the grounds there is a stable designed for four horses. The design of the stable respects modern approach and welfare of horses. The layout of the house and of the stable combines modern and traditional aspects in a way that it fits together with the countryside of Czech-Moravian Highlands. The appendix of this project is the seminar paper dealing with the principles of horse stables design.

The Area of the Horseback Riding Club in the Village Tereziny Dary
Vitík, Jan ; Pařízek, Miloš (referee) ; Kacálek, Petr (advisor)
The aim of the diploma thesis is design an area of a horseback riding club in the village Tereziny Dary in form of project documentation. The area will be used for comfortable housing of small amount of horses and their training for military competition. There are an accommodation for staff, an accommodation for guests, a meeting place for club´s members, a stable for horses, an outdoor riding school and an indoor riding school in the area. For purpose of the thesis the building SO01 – Club Facilities was processed in detailed design documentation. The buildings SO02 – Stable and SO03 – Indoor Riding School were processed in architectural study documentation.

Riding Grounds in Žďár nad Sázavou
Jaitnerová, Vendula ; Blažek, Petr (referee) ; Fišarová, Zuzana (advisor)
The diploma thesis deals with the project of the horse-riding grounds situated near the town of Žďár nad Sázavou. The complex of buildings consists of two riding halls, a groundskeeper’s flat, stables with a zone for riders and outside stable-boxes for horses. The buildings are laid out in a way to create a closed farmyard. There is a built-in unit located in the larger hall together with accommodation and restaurant with a great view to the riding hall. The horse-riding grounds are used for equitation In the first place. The two outside sandy riding arenas and the two indoor halls give an ideal opportunity for regular horse training as well as riders training. The halls would be also useful for holding the riding works all year round. It is possible to stable 19 horses in the indoor stable and 8 more in the outside stable-boxes in the farmyard. This diploma thesis deals with the project of horse-riding hall with a built-in unit, it also deals with a project for the groundskeeper’s flat and outside stable-boxes for horses. In the framework of the diploma thesis two specialties were elaborated – the project for heating in the built-in unit and the groundskeeper’s flat as well as the project for roofing the riding hall with the glue laminated timber girder. There are seminar paper and architectonic sketches included in the diploma thesis.

Band Gap - accurate voltage reference
Bubla, Jiří ; Petržela, Jiří (referee) ; Kolka, Zdeněk (advisor)
This diploma thesis is specialized on a design of a high accuracy voltage reference Bandgap. A very low temperature coefficient and output voltage approx. 1,205V are the main features of this circuit. The paper contains a derivation of the Bandgap principle, examples of realizations of the circuits and methods of compensation temperature dependence and manufacture process, design of Brokaw and Gilbert reference, design of a testchip and measurement results.

LITENČICE CASTLE - A NEW CONCEPT OF RECOVERY OF LAND USE CASTLE GROUNDS
Petrová, Markéta ; Pospíšil, Zdeněk (referee) ; Boháč, Ivo (advisor)
Thesis suggests a recovery of Litenčice castle in the Zlín region. In the current state of the castle it's apparent that in the past fifty years it went through rough times during which it has been decaying or has been inappropriately and inconsiderably renovated. My concept of revitalization is based on a humble approach to the current state and the effort to restore the dignity of this sumptuous mansion. Great emphasis was also put on the eventual execution of the project which is why I changed some of the aspects in order to meet with the owner's vision. Due to high costs of repairs and insurance of continuity of revitalization I was seeking to make opportunities for economic returnability. My aim was to create a complex in which it is possible to spend the weekend with whole family. Renovating the stables makes for an attraction for children just as much as it gives the opportunity travel nearby surroundings by horses. Furthermore, it will be possible to participate in workshops as to reduce the costs of partial repairs notably. As the owner of the castle currently offers the sale of hunting tickets I decided to renovate the premises of the main castle to function as accommodation for these clients. In the event that the above-mentioned objectives were successful it is convenient to think about the consequences. Maintenance of a large object naturally caries the burden of high costs which can be partially eliminated by workshopping, which will be supported by an ecocentre which is placed nearby the stables.

The aim of the master’s thesis is a project documentation of an farm building. It is a new building of stable for breeding of cows of Holstein cattle and accessories necessary for securing it is operation. The building is located in the cadastral territory of municipality Chromeč, district Šumperk. Base consist of a single building object and a stable construction builds up a second object. These two objects are operationally linked and they are connected by the gangway. The stable is designed for a maximum of 278 heads of Holstein cattle. The stable is a single-storey indoor building. In the background there are rooms and equipment necessary to procuring stable operation. A Base is a brick object with two floors. On the ground floor is a waiting room, parlour, technical facilities, rooms for a production of cheese and a cheese shop. Attic there is a background of employees, which is only over a part of the object. Roofs are slanting saddle-shaped. Building estate is situated in the flat terrain.

Sezonní dynamika vnitřních parazitů koní v aktivní stáji
HOŘEJŠOVÁ, Barbora
The aim of this thesis is to provide information on internal parasites, developmental stages and the possibilities of husbandry measures aimed at limiting the occurrence of gastrointestinal parasites in horses. This information is supported by our own analysis in horses observed on a farm in Mazice between 2020 and 2022. The aim was to evaluate the seasonal effect on the dynamics of egg excretion of gastrointestinal helminths of the Strongylidae family in horses kept in an active stable.
