DML-CZ: The Experience of a Medium-Sized Digital Mathematics Library

The Czech Digital Mathematics Library, one of the local digital mathematics libraries (DML) that have emerged world-wide in the last decade is presented. Authors survey basic facts about the project: its goals and how they were met, its structure, content and services offered to users, the experience from the first three years of routine operation in modest conditions, and visions of further development. It is believed that such local DMLs can form feasible building blocks for the envisioned global DML

Production of an alternative fuel from digestate using bio-drying method

Biogas represents one of the renewable sources of energy, which has been growing on use rapidly over the past decades. Biogas is produced during anaerobic digestion of organic material in biogas plants and it is most frequently used for heat and electricity production purposes. There are still plenty of unresolved questions as it is with the other renewable sources of energy. One of the most actual topics is the question of the subsequent usage of a digestate - side product of the biogas production process. Digestate is generally applied as an organic fertilizer for farmlands, but there are tendencies to use its solid phase for another energy producing processes or eventually as farm animal bedding, which is unfortunately connected with few problematic aspects such as transportation and storing of the biologically unstable material with high amount of water in it. Answer to those challenges could be provided by the bio-drying of the digestate's solid phaze - substrate is dried up by heat produced during the microbial decomposition of organic matter and artificial aeration. The main objective of the experimental part of this thesis was to comprehensively test the process of bio-drying of unmodified solid phase of digestate from different biogas plants with agricultural origin for the purpose of...Bioplyn představuje jeden z obnovitelných zdrojů energie, jehož podíl ve využívání v posledních dekádách prudce narůstá. Bioplyn vzniká anaerobní digescí organického materiálu v bioplynových stanicích a je nejčastěji využíván k výrobě tepla a elektřiny. Stejně jako u ostatních obnovitelných zdrojů energie však existuje i v jeho případě řada nevyřešených otázek. Jednou z nejaktuálnějších je otázka dalšího využití digestátu - vedlejšího produktu jeho výroby. Zpravidla je digestát přímo aplikován jako organické hnojivo na zemědělskou půdu, objevují se však i snahy o využití jeho pevné složky (tzv. separátu) jako dalšího zdroje energie, případně jako podestýlky pro hospodářská zvířata. S tím jsou však spojeny další problémové aspekty, zejména přeprava a skladování tohoto biologicky nestabilního materiálu s vysokým podílem vody. Řešení těchto problémů by mohla představovat úprava separátu procesem biosušení, při kterém je substrát vysušován teplem vznikajícím při mikrobiálním rozkladu organické hmoty a umělou aerací. Předmětem experimentální části této práce bylo otestovat proces biosušení na neupravených separátech z různých bioplynových stanic zemědělského typu a dále na separátu z vybrané bioplynové stanice po optimalizaci vstupního složení za účelem jejich dalšího využití jako alternativního paliva....Ústav pro životní prostředíInstitute for Environmental StudiesPřírodovědecká fakultaFaculty of Scienc

The Communist Organization of Children and its Discourse in Czechoslovakia between Two Wars

The submitted study focuses on the issue of the discourse and practice of the children’s and young people’s movement, which was organizationally connected to the Communist Party of Czechoslovakia (CPC). Through descriptions of the organizational base of this movement and an analysis of its discursive and social practices it strives to search for answers to the research questions on the share of the children’s organizations in the creation of the radically left-wing activist milieu around the CPC and the importance of indoctrination in order for it to work. Based on an analysis of the discourse of the children’s party press, flyers, etc., just like the breakdown of the everyday experience of the youngest activists, it uncovers the significance of institutions, such as the family, school, and not least the party in the real world of politically active children and their parents. The article is divided into three parts. The first part describes an organization that was able to capture only a fraction of the young population compared to its liberal nationalist (Sokol) or Christian (Orel) competitors, despite its considerable efforts. The second part presents an analysis of the discourse. It is organized around three themes: firstly, images of an antagonistic class society; secondly, categories that form class consciousness; thirdly, the depiction of competing images of reality as forms of false consciousness. The third part focuses on the practice of the children’s movement, in which discursive symbolic images of discourse were realized with varying degrees of success.Cette étude se concentre sur les discours et les pratiques du mouvement pour les enfants et les jeunes organisé par le parti communiste tchécoslovaque. À travers une description de l’activité organisationnelle de ce mouvement et une analyse de ses pratiques discursives et sociales, elle cherche à répondre aux questions autour de la place de l’idéologie dans la société et autour la part des organisations de jeunesse dans la constitution d’un milieu activiste d’extrême gauche. À partir d’une analyse des discours des tracts et de la presse du parti pour enfants, ainsi qu’une analyse des ruptures dans l’expérience quotidienne que représente pour ces jeunes activistes l’engagement du côté du parti communiste, elle interroge le rôle d’institutions comme la famille, l’école et le parti dans le monde concret de ces enfants et parents actifs en politique. L’article comprend trois parties. La première montre que l’organisation, malgré ses efforts considérables, n’a été capable d’attirer qu’une fraction des jeunes et qu’elle est restée loin derrière ses rivaux libéraux (Sokol) et chrétiens (Orel). La seconde présente une analyse des discours qui est organisée autour de trois thèmes : premièrement la représentation d’une société de classes antagonistes, deuxièmement les catégories qui doivent former la conscience de classe et troisièmement la création d’images au sujet de la fausse conscience. La troisième partie se concentre sur la pratique de l’encadrement des enfants, où le recours aux images rencontre divers succès

Egalitarianism, Welfare Policies and the Legitimation of Political Regimes. The Case of the Czech Republic

Članak se bavi razvojem socijalnih politika u Češkoj tijekom 20. i na početku 21. stoljeća, s posebnim osvrtom na njihovu legitimizaciju. U dijelu literature se razmjerno snažne težnje prema egalitarizmu u suvremenom češkom društvu nakon 1989. godine objašnjavaju kao prežitak komunističkih stereotipa (tj. kao neka vrsta češke inačice ostalgije). Drugi autori to pokušavaju objasniti kroz prizmu povijesti, smatrajući da je riječ o prežitku protestantske tradicije u kolektivnom mentalnom zemljovidu. U radu se iznose argumenti protiv obaju navedenih objašnjenja. Težnje prema egalitarizmu u suvremenom češkom društvu nisu tek puka posljedica života u socijalističkoj diktaturi između 1945. i 1989. Nadalje, vrlo je teško pokazati uzročno-posljedičnu vezu između ranog modernog protestantizma i suvremenog mentalnog zemljovida društva. Stoga se u radu nudi novo objašnjenje dugotrajne veze koja se javila tijekom izgradnje moderne češke nacije između kolektivnog mentalnog zemljovida i strukture društva. Pokazuje se da je ta veza preduvjetom nastanka društvenog konsenzusa koji je temelj legitimizacije svake socijalne politike. Članak se temelji na historiografskim podacima i suvremenim empirijskim sociološkim istraživanjima.Economic and social rights have been effectively used for the legitimation of the political regime both by pluralist democracies and, in their own way, by fascist or communist movements during the 20th century. These rights provide a basis for a type of distributive justice in the modern society. Sociological studies have indicated relatively strong egalitarian tendencies in the Czech society during the post-communist transformation after 1989, which were not easy to explain. In this article we will argue that the explanation should not be sought only by putting forward the obvious argument of the persistence of communist stereotypes or some kind of Czech Ostalgie. Rather, we will try to demonstrate that such egalitarian tendencies could be rooted deeper in the collective experiences shaped by the confrontation with the world wars and the particularities of the formation of the modern Czech nation. We may formulate this statement even more radically. Egalitarian tendencies in the present-day Czech society are not merely a result of the fact that the country was under socialist dictatorship between 1945 and 1989. On the contrary. The birth of a socialist dictatorship after the Second World War made these egalitarian tendencies easier, however the tendencies themselves are historically older, and they formed a strong consensus for the need for social reform in the Czech society, enabling the Communist Party to monopolize power much more easily. This article is divided into three thematic sections. The first one traces the formation of a post-war consensus for reform, which was the basis for the rapid growth of social expenses on both sides of the Iron Curtain, as a result of industrial crises and conflicts following the Second World War. The second part elaborates on the specific issues arising in the implementation of social rights under the conditions of the socialist dictatorship, whereas the third and final part concentrates on the formation of public opinion among the Czech population related to guaranteeing social rights in a transition economy
