Finding Spaces for Urban Food Production – Matching Spatial and Stakeholder Analysis with Urban Agriculture Approaches in the Urban Renewal Area of Dortmund-Hörde, Germany
(Department of Organic Food Quality and Food Culture at the University of Kassel, Germany and Federation of German Scientists (VDW), 2015-05-20)
Using the case of an economically declined neighbourhood in the post-industrial German Ruhr Area (sometimes characterized as Germany’s “Rust Belt”), we analyse, describe and conclude how urban agriculture can be used as a catalyst to stimulate and support urban renewal and regeneration, especially from a socio-cultural perspective. Using the methodological framework of participatory action research, and linking bottom-up and top-down planning approaches, a project path was developed to include the population affected ...

Schlussbericht zum Projekt simject ‐ Simulationsgestütztes logistikintegriertes Projektmanagement im Anlagenbau
(2015-10-22)
Der kundenindividuelle Anlagenbau (z. B. im Bereich Energie-, Kraftwerk- und Umwelttechnik) ist durch ein klassisches Projektgeschäft geprägt und erfordert ein individuelles Projektmanagement in Abhängigkeit von dem zu liefernden Produkt und den jeweiligen kunden- und projektindividuellen Rahmenbedingungen. So steht das Projektmanagement hier vor der Herausforderung, dass Anlagen in Form einer Baustellenfertigung als Unikate realisiert werden müssen, wobei die einzelnen Module häufig an unterschiedlichen Standorten ...

Eigenschaften chromatischer Polynome
(2015-11-02)
Die Berechnung des 1912 von Birkhoff eingeführten chromatischen Polynoms eines Graphen stellt bekanntlich ein NP-vollständiges Problem dar. Dieses gilt somit erst recht für die Verallgemeinerung des chromatischen Polynoms zum bivariaten chromatischen Polynom nach Dohmen, Pönitz und Tittmann aus dem Jahre 2003. Eine von Averbouch, Godlin und Makowsky 2008 vorgestellte Rekursionsformel verursacht durch wiederholte Anwendung im Allgemeinen einen exponentiellen Rechenaufwand. Daher war das Ziel der vorliegenden Dissertation, ...

Information needs for a purchase of fairtrade coffee
(2015)
This research investigates what information German Fairtrade coffee consumers search for during pre-purchase information seeking and to what extent information is retrieved. Furthermore, the sequence of the information search as well as the degree of cognitive involvement is highlighted. The role of labeling, the importance of additional ethical information and its quality in terms of concreteness as well as the importance of product price and organic origin are addressed. A set of information relevant to Fairtrade ...

Ab initio Molecular Dynamics Simulations of the Structural Response of Solids to Ultrashort Laser and XUV Pulses
(2015-04-10)
The theoretical model and underlying physics described in this thesis are about the interaction of femtosecond-laser and XUV pulses with solids. The key to understand the basics of such interaction is to study the structural response of the materials after laser interaction. Depending on the laser characteristics, laser-solid interaction can result in a wide range of structural responses such as solid-solid phase transitions, vacuum phonon squeezing, ultrafast melting, generation of coherent phonons, etc. During my ...

Human and Raptor Interactions in the Context of a Nomadic Society
(kassel university press, 2015)
This research project focuses on contemporary eagle-taming falconry practice of the Altaic Kazakhs animal herding society in Bayan Ulgii Province in Western Mongolia. It aims to contributing both theoretical and empirical criteria for cultural preservation of Asian falconry. This cultural as well as environmental discourse is illustrated with concentrated field research framed by ecological anthropology and ethno-ornithology from the viewpoint of “Human-Animal Interaction (HAI)” and “Human-Animal Behavior (HAB)”.

Magnetic interactions between transition metal impurities and clusters mediated by low-dimensional metallic hosts: A first principles theoretical investigation
(2015-03-31)
The magnetic properties and interactions between transition metal (TM) impurities and clusters in low-dimensional metallic hosts are studied using a first principles theoretical method. In the first part of this work, the effect of magnetic order in 3d-5d systems is addressed from the perspective of its influence on the enhancement of the magnetic anisotropy energy (MAE). In the second part, the possibility of using external electric fields (EFs) to control the magnetic properties and interactions between nanoparticles ...

Integrated bioenergy and food production
(2015)
Rising global energy needs and limited fossil fuel reserves have led to increased use of renewable energies. In Germany, this has entailed massive exploitation of agricultural biomass for biogas generation, associated with unsustainable farming practices. Organic agriculture not only reduces negative environmental impacts, organic farmers were also prime movers in anaerobic digestion (AD) in Germany. This study’s aim was to identify the structure, development, and characteristics of biogas production associated with ...

Adsorption kinetic investigations of phthalocyanine derivatives self assembled monolayers (SAMs) on gold: Temperature influence on the SAM formation process and quality
(2015-08-12)
The ordered nano-structured surfaces, like self-assembled monolayers (SAMs) are of a great scientific interest, due to the low cost, simplicity, and versatility of this method. SAMs found numerous of applications in molecular electronics, biochemistry and optical devices. Phthalocyanine (Pc) complexes are of particular interest for the SAM preparation. These molecules exhibit fascinating physical properties and are chemically and thermally stable. Moreover their complex structure is advantageous for the fabrication ...

Identity and image dynamics – managing social exclusion in profitable way
(Publishing House of the University of Economics, 2015)
The above statement has long been established as the canonical view of economic reality, and it has only been a couple of years since we thoroughly started to contest and debate this world-view. Grasping this, we focus on two aspects about the above perception in detail: First, a suggestion to redefine the term ‘market’ in a more up-to-date fashion, second, the debunking of the suspicious correlation between ‘no money to spend’ and ‘no money to be made’.
