Measuring of the Vertical gravity gradient at the locality TS-73 "Polom", Trutnov - Babí
Pešek, Michal ; Weigel, Josef (referee) ; Pospíšil, Lubomil (advisor)
This master´s thesis deals with the determination of vertical gravity gradient in the shaft below the infantry bunker TS - 73 "Polom" located in village Babí. After performing position, elevation and gravity measurements detailed points, representing the two vertical profiles were calculated gravity, vertical gravity gradient, block densities ang gravity anomalies depending on the depth. Other outputs work as a topographic map and a map of full Bouguer anomalies for the wider area of the location and interpretive geologic profile.

Basic chemical characteristics of juices of selected honeysuckle varieties
Cibulcová, Pavla ; Vránová, Dana (referee) ; Vespalcová, Milena (advisor)
This thesis includes a theoretical part, which speaks about the classification and incidence of honeysuckle plant description, the conditions for growth, recovery, species and varieties. It also includes methods for the determination of selected chemical parameters such as yield, total solids, soluble solids, pH, titratable acidity, formol number and gravimetric determination of reducing sugars.

Review of methods to determining wear in hip replacements
Zapletal, Jakub ; Vrbka, Martin (referee) ; Ranuša, Matúš (advisor)
This bachelor thesis analysis issues of observation and measurement of wear on hip replacements. First of all there is a description of historical milestones in development of hip prosthesis. Afterwards there is a recherché study of measuring methods and devices, whereas each one of them is reviewed for pros and cons. In the last section these methods are compared and there is an author’s recommendation for the most viable method for observation and measurement of wear on hip prosthesis.

Geological and gravimetric pattern of the Ethiopia
Kuznetsova, Alevtina ; Valenta, Jan (advisor) ; Martínek, Karel (referee)
From a geological point of view, Ethiopia is a unique country where active tectonics displays can be studied, in the context of extensive East African Rift System (EARS) evolution, where the Main Ethiopian Rift (MER) is a part. The Main Ethiopian Rift (MER) is typical continental rift structure spread between the African, Somali, and Arabian lithospheric plates stretching over 6,000 kilometres from Syria to central Mozambique. This study of the gravity pattern in Ethiopia reveals significant crustal thinning in the Main Ethiopian Rift and Northern Afar regions. In the southern Afar, the earth's crust has a slightly higher thickness and, moreover, probably contains a significant proportion of the continental crust. The understanding of crustal thinning in the context of active rifting is essential to predict future geodynamic events in that region, which is crucial for the sustainable life of a rapidly expanding population and the necessary construction of infrastructure. This work provides an analysis and re-interpretation of archival gravity data collected from land surface surveys and airborne gravity studies (archive of Geological Survey of Ethiopia) in conjunction with available geological and structural data to evaluate overall gravimetric pattern of Ethiopia and determine main geological...

Structural and metamorphic evolution of thermal aureole of the Krkonoše-Jizera Plutonic Complex
Olšanská, Irena ; Verner, Kryštof (advisor) ; Štědrá, Veronika (referee)
Krkonose-Jizera plutonic complex is one of the largest composite plutonic bodies in the Czech massif. The emplacement of this pluton relates to the origin of the structural and thermal aureole. The processes of contact metamorphism are most evident in the northern and southern part. The topic of this work is to find influence of the contact metamorphism in the host rocks. Partial information about contact metamorphism in this area could be found in several papers, but there aren't work which discuss this topic in detail. Goal of this work is to make complex interpretation of contact metamorphic processes connected with intrusion of the Krkonose-Jizera plutonic complex and use this interpretation for discussion about model of magma intrusion. In rocks of contact aureole of Krkonose-Jizera plutonic complex (KJPC) were identified relicts of Variscan regional metamorphism, connected to creation of regional metamorphic fabric S1 and S2. Original mineral associations and deformation fabrics were in near-contact zone of KJPC 1 km in average in width heterogeneously overprinted by effects of the contact metamorphism, which intensity increases towards the intrusive contact. In the mineral associations of contact-metamorphic rocks appears characteristic minerals such as cordierite and andalusite, rarely...

Geophysical prospection of volcanic structures, in the area of Rybí loučky, Jizerské mountains
Fait, Václav ; Valenta, Jan (advisor) ; Skácelová, Zuzana (referee)
This thesis briefly depicts fundamental principles of three geophysical methods (gravimetry, magnetometry and electrical resistivity profiling), which had been used during research at the Rybí lou ky site in order to clarify local geological conditions. Furthermore, the reader gets acquainted with formation of a maar-diatreme, which is thought to be present at the researched site. The next part describes principles of field measurements and the procedure for evaluation of results. The results are graphically plotted in the last part. Also, the results are compared to previous investigations conducted at this site. Geophysical measurements showed that geological structures on the Rybí lou ky site are much more complex than expected. The simple diatreme structure is most likely not applicable in this case. In contrast, it is not a structure formed solely by a glacier. The origin is most likely a combination of tectonic predisposition, volcanic activity and subsequent selective erosion.
