To extract metals and increase the pH value of water around a historical mine waste deposit a series of barrels are used. Polluted water is forced to pass inside these barrels where different filter materials purify the water. This research project is carried out in Sweden by MTM at Örebro University and Bergkraft in Kopparberg, titled “Methods for characterisation and remediation of historical mine waste”.   The fluid flow trough the filter materials in the barrels are needed to be understood, in order to improve the extracting process.   In this work a small transparent model filled with sand was made to visualise the fluid flow. In that model coloured water is representing the polluted water. To describe the flow in the transparent model a mathematical model is presented. The theory used in this work is the complex variable method in fluid dynamics together with numerical methods and computer programming. There is a pretty good match between the theoretical and experimental results presented in two dimensions. Continuing work could result in a three dimensional model with different geometries using the same technique.

This thesis deals with the history of the Cistercian monastery of Žďár nad Sázavou in the second half of the 17th century, specifically from 1676 till 1705. In 1676, after almost four decades since the Cistercian Order had regained control of the seigniory in Žďár and the convent had been re-established, the monks were allowed to elect their own Abbot. Benedikt Zaunmüller, the prior of the monastery of Vyšší Brod, was elected and remained Abbot of Žďár till 1691 when he was forced to resign on health grounds. He was succeeded by Edmund Bagner, the first of the Abbots of the re-established monastery who was elected from the members of the Žďár convent and remained in office till his death in 1705. The scope of this thesis corresponds with the terms of office of these two Abbots who significantly contributed to the improvement in the economic situation of the monastery and the expansion of the personnel of the convent in Žďár and who are indisputably among the significant personalities of the Žďár Abbey. The outset of the thesis provides an overview of the available archival sources and existing literature on the topic. The first chapter outlines the history of the Žďár monastery from its establishment in the middle of the 13th century. The second chapter captures the transformation of the...

Text in English / This thesis investigates the relationship between humans and the nonhuman world or natural environment in selected literary works by black female writers in colonial and post-colonial Namibia and Zimbabwe. Some Anglo-American scholars have argued that many African writers have resisted the paradigms that inform much of global ecocriticism and have responded to it weakly. They contend that African literary feminist studies have not attracted much mainstream attention yet mainly to raise some issues concerning ecologically oriented literary criticism and writing. Given this unjust criticism, the study posits that there has been a growing interest in ecocriticism and ecofeminism in literary works by African writers, male and female, and they have represented the social, political (colonial and anti-colonial) and economic discourse in their works. The works critiqued are Tsitsi Dangarembga’s Nervous Conditions (1988) and The Book of Not (2006), Neshani Andreas’ The Purple Violet of Oshaantu (2001) and No Violet Bulawayo’s We Need New Names (2013). The thrust of this thesis is to draw interconnections between man’s domination of nature and the subjugation and dominance of black women as depicted in different creative works. The texts in this study reveal that the existing Anglo-American framework used by some scholars to define ecocriticism and ecofeminism should open up and develop debates and positions that would allow different ways of reading African literature. The study underscored the possibility of black female creative works to transform the definition of nature writing to allow an expansion and all encompassing interpretation of nature writing. Contrary to the claims by Western scholars that African literature draws its vision of nature writing from the one produced by colonial discourse, this thesis argues that African writers and scholars have always engaged nature and the environment in multiple discourses. This study breaks new ground by showing that the feminist aspects of ecrocriticism are essential to cover the hermeneutic gap created by their exclusion. On closer scrutiny, the study reveals that African women writers have also addressed and highlighted issues that show the link between African women’s roles and their environment. / English Studies / D.
