Thoughts of Plants
ŠOBROVÁ, Lenka
This diploma thesis called "Thoughts of Plants" consists of two parts, theoretical and practical. The theoretical part focuses on an explanation of the basic thoughts and inspiration that comprise the main resources for the practical part in my thesis. In context of this thesis subject, there is a documentation of the main points in the current art scene, which deals with plant and landscape detail. The practical part is composed of the monumental triptych connected to the subject. This triptych is made of acrylic paint on canvas.
Vegetation of heat pipelines and participation of invasive species
SVĚTLÍKOVÁ, Petra
Both climate change and plant invasions are phenomenons affecting vegetation structure and its functioning. This study compares vegetation of heat pipelines with surrounding vegetation and investigated survival of thermophilic species in the zone on heat pipelines. Reactions of plants on global warming, including possible invasive behaviour of alien species, are briefly discussed.
Rural villages as biocentres. Plants mapping utilization for biodiversity evaluation.
JURÁŠ, Jan
Rural villages are important elements in cultural landscape. Thanks his variety here often enact biocentres and make possible to existence wide spectrum of plant, that could occur in other places and by other conditions only rock hard. At present however happens under the thumb of wasteful management to typical provincial nature suppression and to extinction of some species. This work was bent on vegetation investigation in three villages in Volyňsko in district Strakonice. Ascertained kinds spectrum distinguish on the basis of many factors, for example location position, abiotic factors or way of management. To other subject of interest was derived, let us say invasive kinds occurrence as well as protected species. On the basis these results can tell, that the rural villages are in monotonous agricultural landscape significant biotope that it is necessary to protect.
Phytoremediation of air - plans and reality
Vaněk, Tomáš ; Maršík, Petr ; Soudek, Petr
Results obtained so far indicate that selected plants can be effectively used to remove contaminants from the air, both horizontally and especially near sources of contamination, such as roads. When choosing plants, it is necessary to pay attention to their sorption capacities, as well as their ability to survive in contaminated sites, which are also exposed to other stresses such as lack of moisture and salinity.
Short peptides with antimicrobial activity from plants
Doležílková, Ivana ; Macková, M. ; Macek, Tomáš
Several families of plant antimicrobial peptides have been isolated from different organs and intercellular washing fluids of plants. Antimicrobial peptides were isolated by precipitation of fractions and separared by HPLC and then characterized by tricine electrophoresis.
PHARMACEUTICALS IN URBAN WASTEWATER AND THEIR POSSIBLE DEGRADATION BY PLANTS
Kotyza, Jan ; Soudek, Petr ; Kafka, Z. ; Vaněk, Tomáš
Work is focused on pharmaceuticals in wastewaters and watercourses and their removal by plants. We made short-time hydroponic experiments with Lupinus alba, Hordeum vulgaris and in vitro experiment with Armoracia rusticana L. As a model pharmaceuticals were chosen ibuprofen, diclofenac and paracetamol.
Report for the Project Optimization of Supercritical Fluid Extraction for Maximal Yield of Biologically Active Substances from Plants
Sovová, Helena ; Sajfrtová, Marie ; Pavela, R. ; Karban, Jindřich ; Bárnet, M.
Savory, caraway, peppermint, lavander and ruta were selected out of more than twenty plants as the best resources of biologically active substances soluble in supercritical CO2 and effective against pest insect. Lethal doses and antifeedant activity of plant extracts against four model insect species were evaluated. Chemical composition of isolates was determined using GC and GC-MS. Two novel methods were used to examine relation between the composition and the acute toxicity of isolates.
Equilibrium Concentrations of Solutes Extracted from Plants with Supercritical CO2
Sovová, Helena
Phase equilibrium is the crucial factor for extraction feasibility and rate. In supercritical fluid extraction from plants it depends not only on extraction pressure, temperature, and solvent composition, but also on solute-matrix interaction and on mutual interactions of solutes. A new method for measurement and quantification of these phenomena is reported, as well as some results obtained in the project.
