Measurement of dynamic characteristic of check valves
Novák, Jan ; Himr, Daniel (referee) ; Habán, Vladimír (advisor)
Master thesis presents overview of existing types of check valves, their features, uses and issue called "cracking". Experimental part of this thesis focuses on the lift and swing check valves. Results of the measurement are evaluated from non-stationary flow point of view by developing and analyzing static and dynamic characteristics. This thesis takes into account losses and dynamic effects as main viewpoints. Two methods for measuring non-stationary velocities are used. Direct method called Gibson and indirect method laser doppler anemometry. Goal of the master thesis is to increase understanding of the check valves and their applicability.

The Quaternary Paleoecological Analysis of the Soos National Nature Reserve
Rajdlová, Hana ; Holcová, Katarína (advisor) ; Novák, Jan (referee)
The Quaternary Paleoecological Analysis of the Soos National Nature Reserve The aim of this proposed diploma thesis is to describe the structure of diatom communities in the diatomite deposits of the Soos National Nature Reserve and compare the finding of this thesis with those of older publications. Another aim was to reconstruct the history of the basin trough with the outputs of diatom analysis accomplished in the 3,4 m long sediment profile. The similarity of diatom communites in individual diatomite types was also tested. Key words: subfossil diatoms, Soos National Nature Reserve, paleolimnology, Late Glacial, Holocene

Care of The Soul and Problem of Education
Novák, Jan ; Hogenová, Anna (advisor) ; Prázný, Aleš (referee)
Care of the Soul and Problem of Education The Czech philosopher Jan Patočka shows two different modalities of soul concepts while thinking about Jan Amos Komenský's heritage for contemporary pedagogy. The close-set soul conceptus supposes simply recognizeable world, modern ideas of its controllability and scientific structure scheme. Education, which means care of the soul in three ways - care of the soul in the sense of cosmos order, in the sense of public and in the personal way, means (following close-set conceptus) formation, preparation and setting up the undone young being for life in the modern society. Reflexions of our contemporary situation find out, that modern situation appears as a crisis. This crisis demands a new approach to education, which could be found in the open-set soul concept. The open-set soul could be described as something incomplete, which is searching its fundamentals all the time. Another characteristic shows affinity of the soul for something superior or sense of own finality. Education in this way unveils itself like repeatedly reached humanity. This kind of education does not mean formation or setting up, this kind of education means revealing context of the world, society and finally own personality. Open-set mind should bring responsibility through this revealing....

Natural forest disturbances palaeoecology
Moravcová, Alice ; Pokorný, Petr (advisor) ; Novák, Jan (referee)
This Bc. thesis deals with the disturbances, which form an integral part of many ecosystems. The main foci are natural disturbances (in contrast to anthropogenic ones) of temperate and boreal forests. I deal with the causes of major disturbancy factors (fires, storms, disease and insect pathogens) and their impact on the ecosystem. I focused in detail on fires, because they represent an essential factor in the development of many ecosystems. Moreover, they can be studied in the past by using several tools of palaeoecological analysis: dendroecology, anthracology and pollen analysis combined with micro-charcoal particles quantification. The last part of the thesis discusses the role of disturbances in the secular succession of Holocene vegetation in Central Europe. It contains a chapter that describes a research strategy focused to the study of natural disturbances through paleoecological methods in a specific location (Rynholec, Central Bohemia). Key words disturbances, vegetation dynamics, fire dynamics, secular succession, palaeoecological methods

Environmental Factors In the Pathogenesis of Type 1 Diabetes Mellitus
Horáková, Lucie ; Novák, Jan (advisor)
Type 1 diabetes mellitus is autoimmune disease that is due to the interaction of environmental factors with genetically susceptible terrain. The increasing incidence of T1DM in western countries suggests the existence of environmental factors responsible for the increasing incidence of the disease. The identification of this putative factor is crucial for the development of strategies to prevent type 1 diabetes mellitus. By the analysis of literature, we identified the susceptible factors such as infection (coxsackie virus or cognate rubeola), early exposition to the cow's milk toxins etc. There exist even opposite theories such as hygiene hypothesis suggesting that the development of T1DM might be a result of the lack of protective environmental factor. Available data do not allow to detect causal relation between any of susceptible factors and the development of T1DM and do not allow to develop any strategy to prevent type 1 diabetes mellitus
