Sorption and Stabilization of Metals/Mettalloids by Innovative Synthesized Sorbent Amochar.
Ouředníček, P. ; Trakal, L. ; Komárek, M. ; Pohořelý, Michael
Remediation of contaminated soil which is based on stabilization and immobilization of potential\nhazardous substance by sorption materials has been studied intensively nowadays. Biochar – activated organic carbon belongs to this group of stabilizing agents which can adsorb wide range of contaminants, including metals/metalloids. Surface area of the biochars is quite large in general and functional groups (e.g. COO–) can form chelates or alkaline elements on the surface, which is represented by cation exchange capacity. Altogether with the high pH values (7.00 – 10.00), biochars are quite effective sorbents and can adsorb metals/metalloids from the solution (ground water), especially in acidic soils (in the environments affected by intensive mining activities). Sorption\neffectiveness can be increased (especially for As (V) or Cr (VI) sorption) by modification of biochar by various types of secondary oxides. Innovative sorbent AMOchar (AMO + biochar) has been synthesized currently. The product was prepared by adding of biochar to the reaction solution during amorphous manganese oxide (AMO) synthesis. The AMOchar was formed mainly by Mn-oxalates which had coated surface of the pristine biochar. AMOchar composite was able to remove significantly higher amounts of various metal(loid)s from the solution despite the rather high pH of the material. Sorption effectiveness was high not only in case of Pb (II) sorption (almost 99%), and Cd(II) (51.2%), but also a very high amount of As(V), 91.4%. Additionally, both AMOchar composite was able to reduce Mn leaching. This can avoid potential post-contamination caused by the dissolution of less stable Mn-oxalates as observed in the pure AMO.

Colluvial soils - their characteristics and spatial delineation at chosen study areas in the Czech republic
Zádorová, Tereza ; Šefrna, Luděk (advisor) ; Borůvka, Luboš (referee) ; Sobocká, Jaroslava (referee)
Colluvial soils, formed in areas of increased accumulation of soil material, represent an important element in landscape and soil mosaic, whose development is still in progress. Their spatial distribution and profile thickess are considered to be important indicators of processes leading to significant landscape changes. Their importance also consists in very deep humus horizon which makes them a vast storage of organic carbon. Mapping of colluvial soils represents a substantial contribution in the update process of classic soil maps. The aim of the thesis is a complex analysis of the colluvial soil unit in terms of its relation to soil properties, terrain and geological predispositions and relevance in soil mapping. The study results are based mainly on detailed terrain survey, digital terrian model analysis and modern pedometric methods application. The research was proceeded in three study areas with significant pedological and geological differences and various predisposiotion for colluviation intensity and velocity and resulting character of colluvial profiles. Diverse character of the study areas was the main factor of the spatial distribution and properties of the colluvial soils. In Chernozem region, intensive erosion resulted in formation of colluvial soils characterized by thick humus...

Methods for class prediction with high-dimensional gene expression data
Šilhavá, Jana ; Matula, Petr (referee) ; Železný, Filip (referee) ; Smrž, Pavel (advisor)
Dizertační práce se zabývá predikcí vysokodimenzionálních dat genových expresí. Množství dostupných genomických dat významně vzrostlo v průběhu posledního desetiletí. Kombinování dat genových expresí s dalšími daty nachází uplatnění v mnoha oblastech. Například v klinickém řízení rakoviny (clinical cancer management) může přispět k přesnějšímu určení prognózy nemocí. Hlavní část této dizertační práce je zaměřena na kombinování dat genových expresí a klinických dat. Používáme logistické regresní modely vytvořené prostřednictvím různých regularizačních technik. Generalizované lineární modely umožňují kombinování modelů s různou strukturou dat. V dizertační práci je ukázáno, že kombinování modelu dat genových expresí a klinických dat může vést ke zpřesnění výsledku predikce oproti vytvoření modelu pouze z dat genových expresí nebo klinických dat. Navrhované postupy přitom nejsou výpočetně náročné. Testování je provedeno nejprve se simulovanými datovými sadami v různých nastaveních a následně s~reálnými srovnávacími daty. Také se zde zabýváme určením přídavné hodnoty microarray dat. Dizertační práce obsahuje porovnání příznaků vybraných pomocí klasifikátoru genových expresí na pěti různých sadách dat týkajících se rakoviny prsu. Navrhujeme také postup výběru příznaků, který kombinuje data genových expresí a znalosti z genových ontologií.

The reflection of František Bakule's work in a relation to a current special educational practice
BALÍKOVÁ, Tereza
František Bakule was a significant Czech teacher during the first half of the 20th century. He was known as the first director of the "Jedlicka Institute in Prague" as well as the founder of so-called "Bakule´s Institute" as well as one of the few representatives of the "Czech alternative approach towards education" which is very well recognized all around the world. His legacy and teachings, however, are currently not being developed on the systematic level and neither they are being put into practise by Czech professional mainstream educational community. We also need to mention that is not used by even the stream of special education, in contrast to many foreign alternative pedagogical trends, which are gaining popularity and are generally applied with success. The aim of this thesis is therefore to analyse the work of Frantisek Bakule through the prism of contemporary school educational environment with emphasis on the education of students with disabilities. The first chapter is devoted to outlining the life journey of Frantisek Bakule, particularly focusing on the major milestones that influenced the formation of his personality, his ideas, inspiration and motivation which was reflected in his teachings and then in his very own coherent concept of education. To be specific, we are introduced to his family background and a significant part is then devoted to description of Frantisek´s experience as a teacher, including stages of operating in Jedlicka´s Institute and in his own "Bakule´s institute". The second part is then focused solely on Bakule´s specific educational concept. First, the core principles of the concept are defined. Later parts then talk about Bakule´s original curriculum and a his proposal of an ideal classroom environment. The text also contains a detailed description of how Bakule approached several subjects, which were at the core of his teaching concept, namely "Work activities", "Music education" and "Arts". Original teaching practices are analysed by using current teaching methodology and terminology. Due to the identified aim and goals of the thesis, the third chapter analyses the current concept of education of the above, according to Bakule´s core areas and principles. The text is designed specifically to be subsequently reflecting the work of Frantisek Bakule from the perspective of today's teaching methods, namely the methods of special education. The idea is to define common points and possible differences and uncover hidden inspirational potential, which is then the main content of the fourth and final chapter. Based on the analysis and all its subsequent reflections, the final chapter tells us that although Bakule´s educational goals don´t differ too significantly from the current concept embedded in the relevant framework of educational programs, to achieve such goals we are currently using very different techniques and methods in comparison to Bakule´s ways. Even though Bakule himself tested and verified all of his concepts in practice, which can be very simply described as "do not teach students about life and work, but through life and work", and these concepts also have been proven correct by various subsequent results of psychological researches, the current system still doesn´t draw from them too much. From all the above it is quite obvious that the legacy of life´s work of Frantisek Bakule is currently not utilized nor it is being appreciated by our professional pedagogical community. On the other hand, we need to note that it may also be due to the level of fragmentation in which his concept and materials were preserved to the present days.

Human impact on creating the landscape
Lainová, Dana ; Janků, Jaroslava (advisor)
This bachelor thesis focuses on the differences in landscape structure caused by human influence in nature conservation area Czech paradise. It guide us though period from year 1955 until the present. It take into consideration both the previous and current landscape form, as for land area, landscape character, plant and animal association and abiotic factors. Bachelor work describes particular human influence on forming aspect of this natural heritage. It focuses on forestry and forest cover situation, agriculture and farmland. It does not forget hunting and its related situation of wild animals, fish farming which means purity of water. It will occupies water management and its watercourses modification. Least but not last it concentrates on infrastructure and related development and structural engineering. Attention will be aimed at sewage management, industry and natural raw materials extraction. It has to be mentioned the areas of tourism, mountain climbing and recreation, which should be kept only in marked areas and in accordance with nature conservation. Based on findings from individual areas is possible to compare what an impact did a human being on forming aspect of landscape of Czech paradise from year 1955 until the present. Even for such short time of history, it can be observed large change in landscape character or species association. For the future it will be necessary to reduce intensity of landscape recasting and more focus on conservation of indigenous of this nature heritage.

Performance of private MFIs and financial cooperatives
Neradová, Alena ; Van Damme, Patrick (advisor)
Developing countries have a long-term deal with a financial and economic instability in the current economic environment. Besides others, one of discussed solutions on that scheme is dedicated to microfinance where are evident efforts at delivering inclusive socio-economic development. Thus, the dissertation is focused on the analysis of the relative performance of private MFIs and financial cooperatives in Mediterranean region on selected socio-economic indicators, such as women's employment, education or level of material well-being. The impact of the offered products, such as credit and savings in the attempt to express what types of institutions are providing higher added value to clientele and in what intensity they change selected socio-economic indicator is also significant. Primary data of selected institutions will be inspected on the background of global data structured in the major regions of the world trying to understand the logics, risks and potentials of the development of the microfinance and cooperative sector and their intersections. The output will be a recommendation for the support of the microfinance and cooperative sector.

Impact of agroforestry on dragonflies diversity
Kajzrová, Soňa ; Lojka, Bohdan (advisor)
Tropical rain forests around the world suffer from deforestation, which is caused mainly by small-scale farmers. These farmers largely employ slash-and-burn methods to clear the land for agricultural settlement. Agroforestry systems are widely found in the humid tropics, where they could have great potential to increase the productivity of farming systems and sustain continuous crop production and they are also supposed to conserve biodiversity. As a group of freshwater invertebrates, dragonflies (Odonata) are commonly used as ecological indicators of freshwater ecosystems. The main objective of the study is to assess the impact of land use changes on dragonflies (Odonata) species richness and diversity, namely primary and secondary forest, cocoa agroforest and slash-and-burn agriculture in the Tropical Africa. We hypothesize, that the species richness and diversity of dragonflies decrease with disturbance of the ecosystems, along the land-use changes gradient.
