Study of moisture conditions in the facade wall after application of the ETICS
Ševčíků, Robin ; Steuer,, Radek (referee) ; Šťastník, Stanislav (advisor)
In the last decades the application of ETICS (external thermal insulation composite system) became a popular measure to improve the energy performance and the weather resistance of facades in the building stock. However, hand in hand with that the problem of microorganisms such as algae and fungi on facades has substantially increased in re-cent years. One of the main reasons is the interaction of climate influences with modern compositions of thermal insulation systems resulting besides of large thermal and mois-ture loads in occurrences of green covers of algae on facade surfaces. The algae popula-tion on facades with ETICS is supported by the sufficient humidity, caused by the night temperature decrease of surface to the dew-point temperature and by consequent con-densation of vapour. The thermal radiation against clear night sky is responsible for the origin of this periodically repeated phenomenon. This bachelor’s thesis is concentrated to the description of available knowledge in this field and explains the phenomenons by means of principles of building physics. Moreover, at the end, in the practical part, there are presented the results of author’s own measurements concerning determination of basic properties of commonly used fa-cade materials (spectral emissivity, absorbing power), important with regard to the sub-ject of the thesis.

Use of combination of bacteria and algae for wastewater treatment
Hlavsová, Barbora ; Stříteský, Lubomír (referee) ; Hlavínek, Petr (advisor)
The aim of this bachelor's thesis is to introduce the reader to the ever improving methods of biological wastewater treatment with the use of bacteria, algae and combination of both. Further it elaborates on the promising ways of utilizing biomass gained from these treatments in various sectors, such as energetics, chemistry, pharmacy and agriculture. The second part of the thesis offers a techno-economic study of wastewater treatment using combination of bacteria and algae in a specifically assigned area.

Využití biologických přípravků (řasy, houby, výtažky) při závlaze zeleniny
Kořínek, Jaroslav
Algae has been using in many industrial and agricultural branches since 2 700 B. C. Application of algae, its extracts and preparations containing various extracts -- plant, mycorrhiza fungus, etc. -- in agriculture and horticulture is becoming more and more popular in these days. Several studies proved its positive effect on growth of various plant species. Scientific researches proved its impact on soil quality, growth of roots, plant's growth rate, photosynthesis, plant's quality and yield. Recent studies showed that extracts from seaweed for plant protection prevents from many factors that cause biotic and abiotic stress and also open up a potential of using in terrain. Main reason why biologic preparations should be used in agricultural is salinity and contamination of soil caused by using mineral fertilizers and pesticides.

Využití bioaditiv v produkci bazalky (Ocimum basilicum)
Pečenka, Jakub
This diploma work is focused on the use of bioadditives (products based on algae and bacteria) in the production of basil (Ocimum basilicum). In the literar rewiew, this bioadditives are described generally in terms of their material composition, effect and use in practise. The experimental part deals with a field experiment with basil, which took place in Lednice in the land of the Faculty of Horticulture, Mendel University in Brno in 2013. Basil was divided into 5 variants (4 + control). Individual variants were treated by Amalgerol Premium, EM -- farming Super aktiviert, Pro Milieu Terra and product from Rawat without trade name. The effect of these bioadditives on yield and nutritional parameters of basil were observed. Nutritional parameters were determined from fresh basil matter and from the dried matter. It was the total antioxidant capacity, content of phenols, flavonoids and dry matter. The results show that the application of these products has both positive and negative impact on the monitored parameters in basil. Yield parameters of these preparations were not significantly affected. The greatest effect has Amalgerol Premium and EM -- farming Super aktiviert on increase of total antioxidant capacity. EM -- farming variant was also found to increase total phenols and flavonoids.

How is the Traditional Canadian Value of Volunteering Surviving?
TROUP, Pavel
The aim of this thesis is to test and consequently disprove or confirm the hypothesis that with the large influx of immigrants to Canada, volunteerism might not be able to survive in its present form. In the theoretical part of the work focus has been set on term definition and volunteering classification because it is a structured activity with its own rules and policy. History of volunteering has been described in the following chapter. This part goes beyond the history of volunteering in Canada since it is a deeply rooted Anglo-Saxon tradition which had been brought there by the British and French. The last chapter has been dedicated to the current situation of volunteering in Canada including a profile of a volunteer and possible current threats. The practical part has been based on a survey conducted among York University community members and an analysis of their answers. This survey became, together with my visit to the 2011 Toronto Volunteer Fair and an in-depth interview, the main source for the comparison of practice and theory.

Primary algologic research in basin of Křemžký potok.
VYŽRALOVÁ, Anna
Area of my research was Křemžský potok and ponds in its environs. Křemžský potok situating in Blanský les is being got dirty over time. Polluting influences are caused by villages, which through the stream is flowing. Thereafter a watter in stream is polluted by sewage disposal plant and its tributaries. I found in environs of Křemžský potok and ponds many typical species for this country.

Floristic study of cyanobacteria and algae in south-east part of Vysočina region
MELICHAR, Antonín
The phytoplankton samples from 45 localities in Vysočina region were collected in 2009. Species composition and relative abundance of species were studied; ecological factors like pH, conductivity, temperature, water transparency and dissolved ions were measured. Ecological indices (Shannon and Simpson index of diversity) were calculated and compared with other ecological factors. Checklist of all species present in Vysočina region was made. There were found 262 species and 4 species new for the Czech Republic.

Euglenophytes of the Czech Republic in view of South Bohemia and the Bohemian Forest
JURÁŇ, Josef
A list of photosynthetic euglenoids of the Czech Republic was made from works about algal flora of the Czech Republic and this list was confronted with similar works from the Slovak Republic, Poland, Romania, Ukraine and Slovenia. Following the literature about algae from South Bohemia and the Bohemian Forest a checklist of photosynthetic euglenoids from this area was compiled. Data from this list were completed by my samples from this area. There were found 2 taxons new for the Czech Republic and 3 taxons new for South Bohemia and the Bohemia Forest.
