Management of infectious waste
Martinek, Karel ; Touš, Michal (referee) ; Konečná, Eva (advisor)
The aim of the thesis is the summary of processing rules, handling and disposal of waste from medical facilities in the Czech Republic and comparison of approach with other countries. Legislation of dangerous waste varies from country to country. Slight differences are also observed in the conception of individual regions of Czechia. Increasingly, infectious waste is decontaminated before final disposal by incineration. The thesis provides basic information, advantages or disadvantages of individual decontamination methods and comparison of some of them.

Infectious waste management at regional level
Martinek, Karel ; Pavlas, Martin (referee) ; Máša, Vítězslav (advisor)
Současná pandemická situace ukázala obrovské dopady rozšíření infekce na společnost, i přesto stále ještě chybí jednotný přístup k problematice infekčního odpadu. Cílem této práce je představení metodiky nakládání s infekčním odpadem v rámci regionu v kontextu situace v Česku a Evropské Unii. V teoretické části práce je uveden legislativní rámec, charakter produkce, možnosti dekontaminace a podmínky spalování infekčního odpadu. Na základě těchto poznatků je navržena metodika pro nakládání s infekčním odpadem v rámci regionu. V praktické části práce je pak metodika aplikována na konkrétní region – Královéhradecký kraj. V rámci metodiky jsou navrženy možné scénáře nakládání s infekčním odpadem a vybrány nejvhodnější z nich z pohledu zdravotních rizik, rozpočtové zátěže a dopadu na životní prostředí. Na závěr je metodika kriticky zhodnocena a srovnána s metodikami jiných studií na podobné téma.

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...

Geophysical and gravimetric pattern of Ethiopia, construction, and verification of a new gravity map of Ethiopia

Soil erosion risk analysis in Sidama Region, southern Ethiopia
Bizunhe, Getie Balkie ; Martínek, Karel (advisor) ; Hroch, Tomáš (referee)
Soil erosion is one of the most important environmental issues in Ethiopia. Studies on erosional processes and soil loss rates can provide insight into the landscape evolution, climate change, and human activities, as well as on land degradation risk. The soil coverage of the Sidama Region study area, Main Ethiopian Rift, is characterized by Major Reference Soil Groups as follows: Luvisols, Cambisols, Nitisols, Vertisols, Andosols, Fluvisols, Regosols, and Leptosols. Cambisols and Luvisols are more susceptible to erosion. Revised Universal Soil Loss Equation (RUSLE) is most developed and recently widely used algorithm which was used to map and estimate the spatial distribution of soil erosion rates in the study area. Two rainfall datasets and three soil structure datasets were tested for reliability. The resulting 6 RUSLE calculations were validated by field mapped polygons in selected areas. It showed that most reliable input datasets are new more complete rainfall data and soil structure data derived from field mapping and sample analysis. The most susceptible areas of soil loss are mapped and the mean soil loss rate in the study area is 28 t/ha/yr. The mean annual soil loss of Sidama study area is above the tolerable mean soil loss (18 t/ha/yr for Ethiopian highlands). The Revised Universal Soil Loss...

Utilising satellite imagery for geological mapping and structural analysis
Sokolová, Anna ; Lexa, Ondrej (advisor) ; Martínek, Karel (referee)
The use of remote sensing data is becoming very important in Earth sciences. Satellite images are invaluable for studying hardly reachable places on Earth and they can significantly help increase the efficiency of work in areas with existing field data . In arid areas where rocks are exposed and directly visible at the surface, a lithology contacts mapping can be done based on satellite images. An overview of the possibilities of processing multispectral images is included in the theoretical part of this thesis, as well as a description of previously known methods for performing structural analysis based on remote sensing data. As the main part of this thesis, a new method for finding orientations of planar geological structures including a quality control of the input data was developed and described. This method was then applied in the Bodonchin area of the Mongolian Altai where the metamorphic foliation and pegmatite veins were analyzed. The method showed good applicability in the given area despite its limitations which are also discussed in the thesis.

Quaternary climate and origin of eolian deposits
Obersteinová, Tereza ; Kadlec, Jaroslav (advisor) ; Martínek, Karel (referee)
The Quaternary climatic conditions have controlled the origin of eolian deposits. The loess/paleosol sequences represent a valuable natural archives used for understanding of Quaternary climate and stratigraphy. Loess deposits cover about 10% of the continent areas. We can compare a proxy-record from these sediments, often from distant areas, to get knowledge of global significance. The applied mineral magnetic analyses enable understand the paleoenvironmental signal preserved in the loess/paleosol sequences and compare it with a proxy-record obtained from deep ocean sediments

Geochemical study of the lacustrine deposits of the extinct Komořany Lake
Valentová, Daniela ; Martínek, Karel (advisor) ; Beneš, Jaromír (referee)
Komořany Lake, regarded as one of the most important sites of the Czechoslovak Quaternary, was situated at the southern foot of the Krušné hory Mountains, northwest from the Starý Most town, between the villages of Souš, Komořany, Ervěnice, Dřínov, Albrechtice, Černice and Dolní Jiřetín. Due to its size, Komořany Lake belonged to the largest bodies of water in the Czechoslovak Republic (25 km2 ) and due to the quantity of organogenic sediments get into the focus of paleoecologists. Gyttji sediments which occupy comparatively thick position in the lake infilling, formed a continuous record from the Last Glacial period to the Subatlantic period and up to now have been processed mainly from the paleoecological point of view. In this work the organogenic sediments are studied from the sedimentary record using modern geochemical methods (TOC/TN and d13C) for the first time in Komořany Lake history. The work was based on profiles (PK-1-C, PK-1-Ch, PK-1-I and PK-1-W) which were taken between 1977-1983 before a complete exploitation of Komořany Lake sediments as a result of coal mining in the Most Basin in the 1980's.
