Polycentric urban forms: The relevance of scale for metropolitan and city planning
Malý, Jiří; Krejčí, Tomáš
2021 - English
The paper deals with the importance of scale in metropolitan and urban planning, in connection with the promoted and often applied concept of polycentric development. Although the normative conceptualization of polycentricity to some extent reflects the multi-scalar dimension, the operationalization of the concept encounters a number of limitations and fuzzy meanings that result from different scales of analysis and interpretation. Using the Czech context of planning practice, the negligence of the importance of overlapping geographical scales and limits of binding spatial planning materials is documented. The dependence of polycentricity on the scale has consequences both for the analytical evaluation of the spatial situation of the settlement system and for the subsequent interpretation of the results and the setting of further development strategies.\n

RTIN-based strategies for local mesh refinement
Kolcun, Alexej; Sysala, Stanislav
2021 - English
Longest-edge bisection algorithms are often used for local mesh refinements within the finite element method in 2D. In this paper, we discuss and describe their conforming variant. A particular attention is devoted to the so-called Right-Triangulated Irregular Network (RTIN) based on isosceles right triangles and its tranformation to more general domains. We suggest to combine RTIN with a balanced quadrant tree (QuadTree) decomposition. This combination does not produce hanging nodes within the mesh refinements and could be extended to tetrahedral meshes in 3D.

Resuscitation of landscape painting by research of landscape changes
Havlíček, M.; Slach, T.; Skokanová, H.; Halas, Petr; Kallabová, Eva; Koutecký, T.; Šebesta, J.
2021 - English
An analysis of selected landscape paintings shows that only a third of them are located directly on a hiking trail, bike path or nature trail. In the case of other landscape paintings, it is possible to make other, hitherto neglected parts of the territory more attractive to tourists by locating the places of the painter's shots, which may lead to their desired deconcentration from the places that are frequently visited by tourists.

New opportunities for geotourism development at geoarcheological site Holedná Hill (Brno, Czech Republic)
Kubalíková, Lucie; Kirchner, Karel; Kuda, František
2021 - English
Special Interest Tourism is often seen as a form of ‘alternative’, ‘ethical’ or ‘environmentally responsible’ tourism and it occurs when the tourists’ motivation and decision-making are primarily determined by a particular special interest with a focus either on activities and/or destinations and settings and search for novel experiences (Novotná et al. 2019). \nOne of the types of sites are called geocultural sites (Reynard and Giusti 2018). Geoarcheological sites can be considered a type of geocultural sites and can be defined as sites where geological aspects are accompanied and closely related to archaeological issues. \nThe Holedná Hill (Brno, Czech Republic) can be considered an example of such geoarcheological site. It is important from the Earth-science point of view and it includes specific archaeological issues that are closely related to the geodiversity. This paper briefly sums the natural and cultural values of Holedná Hill and based on the geomorphosite assessment and SWOT analysis.\n

Anthropogenic relief transformations - their knowledge and evaluation with regard to the uniqueness and cultural identity of regions
Kirchner, Karel; Kubalíková, Lucie; Kuda, František; Havlíček, M.
2020 - English
Within the development of new regional geography, the role of human geographic research in the study of regions is emphasized. Regional uniqueness, a consciousness of belonging to a particular However, physical geography disciplines, e.g. geomorphology, can also contribute to the knowledge of these aspects with regard to the definition of regions. Currently, within the framework of geomorphology, attention is paid to the diversity of anthropogenic landforms. The knowledge and evaluation of these anthropogenic landforms, which are an important part of the historical elements of the landscape and are also referred to as cultural artefacts of the landscape, enables to supplement the cultural-historical values of the region and to specify the cultural identity of the region. On the example of sites - Staré Hradisko and Hostýn - we will present the specifics of secondary geodiversity with respect to the cultural identity of the sites.

Geological paths – their use for the regional geography teaching
Kubalíková, Lucie; Drápela, E.; Bajer, A.; Zapletalová, D.; Balková, M.; Zágoršek, K.; Kirchner, Karel; Kuda, František; Roštínský, Pavel
2020 - English
Geological paths (geopaths, geotrails) represent a type of educational paths that connect sites, which are interesting from the Earth-sciences point of view. These sites (e.g. outcrops, old quarries, historical buildings built of local stone or viewpoints) often represent the links between geodiversity and other phenomena within a region (which is in accordance with a holistic approach to geotourism). Thus, they can give complex information not only about the abiotic nature but also about biodiversity, history or culture of the region, usually through narrative. Suitable interpretation of geodiversity and its relationships to the biodiversity and cultural heritage allows to identify regional specifics, it helps to find the mutual connections between particular phenomena within the region and it supports the holistic perception of a given region. The contribution presents an example from the Brno city where the urban geopath can be used for teaching regional geography of Brno and its surroundings.

Developing urban geotourism in Brno (Czech Republic)
Kubalíková, Lucie; Kirchner, Karel; Bajer, A.; Balková, M.; Kuda, František
2020 - English
The term “urban geotourism” is defined as tourism based on the places within the city boundary (both in the form of built heritage - monuments, buildings, statues - and rock outcrops) that is related to geological concepts and features. As a first step for the development of urban geotourism it is necessary to identify and inventory the geotourist resources, which should take into account both natural (geological, geomorphological, hydrological or palaeontological, and ecological aspects related to geodiversity), and cultural aspects related to geodiversity (e.g. monuments, building stone, geo-toponyms, anthropogenic landforms). Based on the classification of geotourist sites, selected examples from Brno (Czech Republic) are given, supplemented by geotourist and geo-educational activities. In the conclusion, the advantages of urban geotourism are summarized and its importance for the protection of abiotic nature and sustainable management of valuable sites is suggested.\n\n

Residual ancient landscape segments in Carpathians of Moravian-Slovak borderland
Kolejka, Jaromír; Nováková, Eva; Kirchner, Karel
2020 - English
The Moravian Carpathians border region is a large area located in the east of the Czech Republic. Historically, most of the time it was a peripheral border area between the Czech state and Hungary. The well-preserved segments of pre-industrial landscape were inventoried here. They have such arrangement of land use, which originated in the period before the main wave of the industrial revolution in the Czech lands (i.e. before 1850), and has been preserved until present. A total of 182 segments of pre-industrial landscape were identified. Spatial analysis of their location in the area shows that the highest concentration of segments is near the international border (50% up to 10 km from the border), in dissected highland relief (52%), but often in the foothills between 300-500 meters above sea level (51%). Due to their location and appearance, they can represent interesting geotourist objects in the border area.

Characterization of fine-grained montmorillonite fractions suitable for composite preparation
Valovičová, Věra; Vaculíková, Lenka; Plevová, Eva; Dolinská, S.; Znamenáčková, I.; Danková, Z.
2019 - English
The aim of this experimental study was to characterize a fine-grained fraction of montmorillonites (SAz-2, STx-1, SWy-2 and Kunipia-F). It was investigated in order to provide more precise information of used montmorillonites than could be obtained by analysis of the unfractioned montmorillonites. At first, the fine fraction of montmorillonites were prepared by sedimentation and activation by means of Na2CO3. The prepared clay materials were characterized by the X-ray diffraction analysis and FTIR spectroscopy. The thermal behaviour of the studied samples was determinated according to the characteristic temperatures obtained from TG/DTA curves. The temperatures of dehydratation and dehydroxylation were evaluated and kinetic parameters were also calculated. The porosity and surface properties of the studied samples were gained by the nitrogen adsorption measurements. The obtained results confirmed that the fine fraction of montmorillonites could be a suitable material for subsequent preparation of composites with enhanced sorption properties, especially montmorillonite/MnO2 composite.

Adsorption of pharmaceuticals from aqueous solutions onto clay minerals
Vallová, S.; Sokolová, B.; Valovičová, Věra; Plevová, Eva
2019 - English
The objective of this work was to investigate to possibility of clay minerals for the removal of drugs from aqueous solutions. Natural minerals such as montmorillonite, vermiculite, kaolinite and modified montmorillonites KSF and K10 (intercalated by Fe3+) were used as potential sorbents for three analgetics: paracetamol, ibuprofen and diclofenac from aqueous solutions. This research demonstrated that adsorption of all three pharmaceuticals onto natural untreated clay minerals, except paracetamol sorption on Na-MMT, is negligible. On the other hand, the chemically modified montmorillonites demonstrated significant sorption ability in the order diclofenac>ibuprofen>paracetamol.
