The application of plant-derived biologically active substances for shelf-life improvement of elderflower syrup
Grosmanová, Anna ; Klouček, Pavel (advisor) ; Fraňková, Adéla (referee)
The aim of this thesis was to find biologically active substances that would be
suitable as natural conservatives for herbal sirups, in our case elderflower sirup.
Because esential oils are among biologically active substances well known for
their antimicrobial aktivity we chose thyme, lemongrass and clove bud essencial oils to
be tested on the eldeerflower sirup.
Potencial use in a private small scale production was one of the reasons for this
particular topic and therefore its technological inovation.
The emulgated essential oil was mixed with the sirup and observed for 14 days
for the colonies forming units (CFU) which was determined by the drop plate technique.
Cultivation was done at a room temperature 22° C as its expected by the consumer that
sirups may be stored this way. After the cultivation the numbers of colony forming units
were counted and turned into a logaritmic value.
Clove essential oil proved a significant difference between control specimen and
the essential oil preserved specimen. Statistically remarkable corelation was found also
between different concentrations. As well as clove, lemongrass essencial oils proved
certain antimicrobiologial activity also with statistical significance. Thyme essential oil
proved antimicrobiological activity as well only with no significant difference between
concentrations.
Essential oils are suitable as natural conservatives for not only their proven
antimicrobiological activity but also low price and easy application.

Konzervace kukuřice silážováním
BROŽ, Petr
Modern livestock production is in many ways a progressive discipline, which is characterized in that it blends several seemingly unrelated industries. One of the most important nutrition and feed livestock. With the development of the cultivation of maize (Zea mays), and the need for its preservation, it was necessary to develop a methodology proper ensiling. This practice establishes the correct principles for the production of high-quality, nutritional value and harmless silage. It already belongs to the selection of the optimal hybrid, suitable agronomic measures during cultivation, build a functional and efficient silage lines, selection and application of additives, proper layering and ramming masses and responsible handling of ready-made food, including a ration.

Strojní linky pro senážování
Práza, Martin
This bachelor thesis describes the various stages in production of roughage from wilted forage by silaging. There are machines and machine lines that are suitable and necessary for the operation. The practical part of the thesis is focused on technical-economical estimation of the transport line for collectioning of cuted forage from the field. There were monitored turnover time, weighed amount and fuel consumption of the transport lines.

Evaluation of industrial heritage
Navrátil, Oldřich ; Králová, Eva (referee) ; Zemánek, Václav (referee) ; Ryšková, Michaela (referee) ; Zemánková, Helena (advisor)
The main subject is evaluation of effective use in terms of care (not only within protection of monuments) in order to save and protect industrial heritage. Pointing out on critical issues connected with the end of production of traditional branches which played the key role in historical development of our cities. Nowadays abandoned buildings and sites are represented by memory of the place or its prosperity. New owners often don't share the positive approach to the industrial heritage, developers are seeking new sites, cities and inhabitants have developed new needs through the time. The work will demonstrate examples within European context and will make recommendations in monitoring and classification of industrial heritage to prevent undo able losses.

Dlouhodobá péče o sochařská díla a díla uměleckých řemesel z kamene v krajině
Novotný, Jiří ; Lesniaková, Petra ; Halda, Josef ; Kaše, Jiří ; Kotlík, Petr ; Štaffen, Zdeněk
Předkládaná metodika byla vytvářena v letech 2012-2015 v rámci řešení projektu NAKI č. 27 vedeného pod názvem „Dlouhodobá péče o sochařská díla a díla uměleckých řemesel z kamene v krajině“ financovaného MK ČR. Podkladem pro vypracování této metodiky je mnohaletá restaurátorská a pedagogická činnost doc.Jiřího Novotného akad. soch. na FR a na řadě významných památek, mezi nimiž sochařská výtvarná a architektonická díla zhotovená z kamene, zvláště z pískovce, zaujímají významné místo.
Na tvorbě metodiky se podílel kolektiv odborníků složený z různých oborů participujících na péči o památky: P. Lesniaková, R. Tišlová, P. Dvořák, J. Halda, J. Kaše, P. Kotlík, Z. Staffen. Metodika se na interdisciplinárním základě zabývá postupy, které se v rámci dlouhodobé péče podílejí na poučené přípravě prací na památkách - sochařských a uměleckořemeslných dílech z kamene. Metodiku, která může být základem pro systematické poznání aktuálního stavu památek v jejich historické zprostředkovanosti, které lze využít při identifikaci díla, popisu a zhodnocení závad a postižení možných příčin, jejich vzniku. Získané údaje následně slouží zpracování materiálů pro posouzení přípravy prací na památce, zpracování plánů dlouhodobé péče, přípravy podkladů pro přípravu restaurátorských záměrů a vč. jejich základní koncepce. V metodice je vytvořen systém po sobě jdoucích kroků směřujících k hlubšímu poznání materiálové i výtvarné struktury památky a postižení jejich současných i možných budoucích významů pro nás.

Conservation of corn silage
KŠANDA, Martin
This bachelor thesis deals with using of maize for production of silage that has a high potential and that are an irreplaceable part of a cattle nutrition. The introductory part focuses on the origin, characteristics and description of individual parts of plants. This chapter is followed by a mention of the posibilities and use of silage hybrids of maize. Following chapter describes the procedure of conservation and fermentation. The thesis also mentions microorganisms that have a positive as well as negative influence on the whole procedure. An interesting chapter is an introduction ofa silage additives. The conclusion is about constructions that are used for silage. One of the most important parts of a thesis is a technological description of the procedure of silage, together with harvest methods and factors, which are of great importance for a final product- a good quality and eneregy- rich feed, that a corn silage undoubtedly is.

Revitalization of the former Bata's factory in Zlin
Horníčková, Nela ; Lindner, Milan (advisor) ; Zelený, Martin (referee)
Bachelor's work is focusing on problematics of monument care, redevelopment and conservation of industrial culture heritage. Theoretical part is closely connected to the problematics this work is dealing with. Practical part is focusing on re-use of factories nowadays, on change which is visible from since the area was founded, by the time we are looking for the new options and opportunities for its use and purpose. Also the attempt is to look more closely if today's function of the area is on behalf of inhabitants needs and whats more if there is still a bit of Bata's legacy and atmosphere which the city surely deserves.
