The thesis presents an investigation of the question whether it is viable for the English company Essential Care to introduce a direct selling channel in the United Kingdom. The thesis provides an outline of the direct selling and labour market in the United Kingdom, including organisations and legislation for direct selling. A SWOT analysis illustrates the external and internal factors that could have an influence on the feasibility of the project. The main part of the thesis focuses on a market research survey which was conducted in the United Kingdom. Followed by an analysis of the results it provides a detailed outline of the findings. At the end of the thesis the overall findings are summarised and recommendations for Essential Care are presented.
The primary objective of this work and the research at the “Helmholtz-Zentrum für Umweltforschung” was to gain a deeper understanding of the basically transformation processes, especially for nitrogen species, in constructed wetlands. Therefore two different types of laboratory scale model systems, run with two different artificial wastewaters, had been observed for about 4 months. Data about the situation of three nitrogen species (ammonium, nitrate, nitrite), the physical condition of the pore water and the carbon sources contained by the water had been collected and compared. The present work will provide a summary about the actual knowledge of the microbial processes in constructed wetlands and the general character of such constructions. It will explain the different methods used to gain the data which will be later wards discussed with the aid of the created graphs in the final argumentation.

The bachelor thesis is about cis-trans isomerization of Xaa-Pro (Xaa = any amino acid), their quantitative acquisition and the selection of 3D structure information for the prediction with a support vector machine (SVM). The quantitative detection of occurrence of cis-, trans- and cis/trans conformation in membrane proteins will be examined and evaluated. The 3D structure informa-tions include 12 features, the amino acids around proline and are including of proline. These include the inside/outside classification, the real secondary structure, energy consideration, as well as five further amino acid occur properties within a defined radius of the proline. From this information, a data set was created for the SVM. This program is used for the prediction of unknown and known Xaa Pro Isomerisms. The methods for the analysis were implemented with the platform independent programming language Java. Two programs have emerged from the work to a Xaa PIPT for the quantitative detection and extracting structural information and m Xaa-PIPT to the pure prediction of Xaa-Pro isomerism in protein structures. 389 Membrane proteins from the PDB (Protein Data Bank) served as a basis. The data were also statistically analysed and evaluated.
In this work a new method for the prediction of the Xaa-proline (where Xaa is any amino acid) cis/trans isomerization was investigated. By extraction of twelve structural features (real secondary structure, inside/outside classification, properties of the environment around proline and proline itself) a support vector machine (SVM) based prediction approach was evolved. The Java software Xaa-PIPT for structural feature extraction was developed. Based on 4397 (2199 cis and 2198 trans) prolines extracted from non-redundant, globular proteins a classifier was trained using the radial basis function (RBF) kernel. In ten-fold cross-validation it achieved an accuracy of 70.0478 % and a Matthews correlation coefficient (MCC) of 0.4223, a sensitivity of 0.5433 and a specificity of 0.8576. Based on this classifier a lightweight and easy-to-use Java software tool, called m Xaa-PIPT, for the prediction of the Xaa-proline cis/trans isomerization was devel-oped. It was shown that there are correlations between the proline surrounding environment and the isomerization state. m Xaa-PIPT can be used for the evaluation of low-resolution protein structures and theoretical models to improve their quality by the prediction of the Xaa-proline isomerization.
This paper explores the origins of Maori images in New Zealand film history. Discussing the history of Maori and their society brings us closer to a, once almost extinct, race and its struggle for self-representation and self-governance. By taking an in-depth look at New Zealands film history we get to understand how Maori were the subject of the earliest films and at what time they started making their own films. Combining those elements gives us the opportunity to understand how early images of Maori were created by Pakeha directors. By looking at different films throughout film history shows how Maori images evolved in time, especially when Maori started depicting themselves. This paper not only answers questions about Maori images in film but also tries to make people realise what odds Maori had to overcome in their daily struggle for selfdetermination.
This feasibility study shows possibilities, how logistical concepts can be
improved or reorganized. Therefore, the assambly line for hydraulic blocks at
Bosch Rexroth Changzhou is checked and new ideas are shown. To ensure
comparability, three different cases are considered. Based on this evaluation,
recommendations for further development are displayed.
