Making the Land Cultural

Cultural Landscape Drinkers for cattle For my bachelor thesis I chose the topic which is dealing with the landscape and man's relationship to it. The selected area is unused rural landscape with almost no use at this moment. The project, among other things deals with the design of site-specific objects, sometimes land art installation. Javorníky valley, between the villages Bohuslavice u Zlína and Salaš, was consisted of a small fields. In 70s they built a fence around the valley with a drinkers inside and they began graze a cattle. Field were changed into pasture for several years . But already in the 80s was pasture canceled and cultural quality of the valley began to deteriorate. Present day, the area is primarily for hunting, cultivated by local Hunting Association. The result looks that the valley is overgrown, most of the meadows are not to mowed and the forest is expanding. The journey disappears. No one other is interested in the local landscape, and is here just a fewwho are attend it. My project uses construction of drinkers which are deployed in the valley. A concrete blocks with metal structures can serve as a basis for sculptural and architectural objects. Places in the landscape that have lost their meaning can be reused. And hopefully it will help to attract the people back into the landscape.

This Way That Place
Hašková, Tereza ; Trejbal, Jan (referee) ; Ambrůz, Jan (advisor)
The topic of the bachelor's thesis is the landscape in the student's place of residence. The concept of the bachelor's thesis is primarily the perception of the cultural landscape. Emphasis is put on artistic interventions with the socializing potential, which can be the reason for meeting the locals, sources of aesthetic experience, pleasant leisure time, walking or sports. The work has the ambition to reveal unusual perspectives, to offer possibilities and experiences with different perceptions of the village in the valley, for centuries formed in the logic of the local landscape and the resulting human needs. The tangible output of the bachelor's thesis is the locally unique work of art, a vantage point that will become part of the intended series.

Parliament of the Czech Republic and the European Union
Trejbal, Jakub ; Grinc, Jan (advisor) ; Syllová, Jindřiška (referee)
Parliament of the Czech Republic and the European Union ABSTRACT What are the effects of European integration on the functioning of the Parliament of the Czech Republic and how does the European law set the boundaries for the involvement of this key constitutional institution in European affairs? To what extent do the Chamber of Deputies and the Senate deal with the European agenda and engage in European Union policy-making, and are there differences between them in this respect? What is the role of both chambers in the European legislative process and what is the level of their activity compared to the activity of parliamentary chambers of other EU member states? The search for answers to these questions is the focus of this thesis. The first part of this thesis defines the concept of a parliament and its functions and powers as understood in theory, followed by a general characterisation of the Parliament of the Czech Republic, its two chambers and the constitutional basis for their involvment in European affairs. The second part introduces the major milestones in the history of European integration that have shaped the relationship between the Parliament of the Czech Republic and the European Union and an assessment of their impact on the functioning of national parliaments. The third part analyses...

Plasma treatment impact on physical and chemical properties of polymeric fibers
Hlůžek, R. ; Prošek, Z. ; Trejbal, J. ; Fládr, J. ; Potocký, Štěpán
Presented work focuses on chemical and physical properties of plasma modified polymeric macro-fibers. Polyethylene terephthalate (PET) and polypropylene (PP) fibers having approx. 300 mu m in diameter were modified using cold oxygen plasma in order to achieve their surface changes needed for durable bond and adhesion with cement matrixes. A duration of plasma modification differed between 5 to 480 seconds, where an effect of the treatment was examined. Fiber surfaces chemical changes were researched via wettability measurement with demineralized water (the measurement was repeated immediately and after 1, 7 and 30 days to find out the changes stability). Physical changes were studied by means of weight balance (determination of weight loss) and tensile strength tests. It was found that wettability was enhanced significantly - up to two times, while mechanical properties of treated fibers decreased only slightly.\n

Performance of cement composites reinforced with surface-modified polypropylene micro-fibers
Antoš, J. ; Dejdar, L. ; Trejbal, J. ; Prošek, Zdeněk
This paper focuses on the mechanical properties investigation of cement pastes reinforced with surface treated polymer fibers. The cement matrix was composed of Portland cement (CEM I 42.5 R, w/c ratio equal to 0.4). Two polypropylene fiber types (micro-and macro-fibers) were used as randomly distributed and oriented reinforcement in volume amount of 2 %. The fibers were modified in the low-pressure inductively coupled cold oxygen plasma in order to enhance their surface interaction with the cement matrix. The investigated composite mechanical properties (load bearing capacity and response during loading) were examined indirectly by means of four-point bending mechanical destructive tests. A response of loaded samples containing treated fibers were compared to samples with reference fibers. Moreover, cracking behavior development was monitored using digital image correlation (DIC). This method enabled to record the micro-cracks system evaluation of both fiber reinforced samples.\n

Wettability enhancement of polymeric and glass micro fiber reinforcement by plasma treatment
Trejbal, J. ; Šmilauer, V. ; Kromka, Alexander ; Potocký, Štěpán ; Kopecký, L.
Plasma treatments were used to modify surface properties of polyethylene terephthalate (PET) and glass micro fibers, to improve their wettability. PET fibers, having diameter of 400 μm, and glass fibers (14 μm) were exposed to low pressure oxygen plasma. A direct horizontal optical method was used for contact angle measurements on fiber surfaces submerged into distilled water. Surface morphology changes before and after treatment were characterized by scanning electron microscopy. Finally, cement paste specimens reinforced with PET and lime-based mortars reinforced with glass fibers were made and after 28 days of mixture curing tested by four-point bending tests. After oxygen plasma treatment contact angles decreased by 60 % on PET fibers and by 25 % on glass fibers in comparison with untreated fibers. Next, SEM images revealed the significant surface damages of PET fibers and minor damages of glass fibers. Both four-point tested samples reinforced with treated fibers exhibited the maximum bending strength loss about to 10 to 20 percent compared to samples with untreated reinforcement.
