Verfassungsrechtliche Analyse der Modernisierung des Besteuerungsverfahrens
(2023)
Große Teile des „Gesetz[es] zur Modernisierung des Besteuerungsverfahrens“ traten am 1. Januar 2017 in Kraft. Mit diesem Gesetz wollte der Gesetzgeber eine Zeitenwende im steuerlichen Verfahrensrecht einläuten, indem er die seit langem in der Verwaltungspraxis verwendete Möglichkeit, Verwaltungsakte ausschließlich automationsgestützt zu erlassen, erstmals gesetzlich regelte. Kernstück dieses Gesetzgebungspaketes ist die erstmalige gesetzliche Regelung eines Risikomanagementsystems zur Prüfung von Steuererklärungen.

Characterisation of Cold Asphalt Mixtures with the Addition of Active Fillers
(2023)
Climate change, the limited availability of natural resources, and energy crises are putting pressure on the global societies? to employ low-energy and low-emission technologies for road pavement construction. Cold Recycled Materials (CRM) is an efficient and low-impact solution. CRM with Bituminous Emulsion (CRM-BE) is one of the most common types of CRM. CRM-BEs are created at ambient temperature by combining a high amount of Reclaimed Asphalt (RA) with Bitumen Emulsion (BE). BE used in CRM is typically composed ...

Capital Accumulation, Sector Productivity, and Economic Growth
(2023)
This dissertation is motivated by the research results of Benigno and Fornaro (2014). Benigno and Fornaro (2014) research, how low interest rates impact the productivity of economies.
This dissertation implements extensions of the Benigno and Fornaro (2014) model, that particularly address the capital accumulation, the production functions, and the technology accumulation. In doing so, this dissertation shows that some of the Benigno und Fornaro (2014) research results require specific assumptions, to qualitatively ...

Design, implementation and application of a generic framework for integrated regional land-use modeling
(2008-02-19)
Land use is a crucial link between human activities and the natural environment and one of the main driving forces of global environmental change. Large parts of the terrestrial land surface are used for agriculture, forestry, settlements and infrastructure. Given the importance of land use, it is essential to understand the multitude of influential factors and resulting land use patterns. An essential methodology to study and quantify such interactions is provided by the adoption of land-use models. By the application ...

Preparation and applications of periodical gold nanoparticle arrays
(2009-07-14)
Diese Arbeit beschäftigt sich mit der Herstellung und Anwendungen von periodischen Goldnanopartikel-Arrays (PPAs), die mit Hilfe von Nanosphären-Lithografie hergestellt wurden. In Abhängigkeit der verwendeten Nanosphären-Größe wurden dabei entweder kleine dreieckige Nanopartikel (NP) (bei Verwendung von Nanosphären mit einem Durchmesser von 330 nm) oder große dreieckige NPD sowie leicht gestreckte NP (bei Verwendung von Nanosphären mit einem Durchmesser von 1390 nm) hergestellt. Die Charakterisierung der PPAs erfolgte ...

Die Beschreibung professioneller Handlungskompetenz von (angehenden) Lehrkräften in schulischen Praxisphasen
(2023)
Die Dissertation untersucht die subjektive Beschreibung professioneller Handlungskompetenz von (angehenden) Lehrkräften in schulischen Praxisphasen und ist in vier Teilkapitel gegliedert.
Der theoretische Rahmen bildet den ersten Teil der Arbeit und befasst sich mit der Frage, was die professionelle Handlungskompetenz von Lehrkräften ist, wie sie erfasst werden kann und welche theoretische Einordnung vorzunehmen ist. Drei Abschnitte geben Aufschluss über das Modell der professionellen Handlungskompetenz von ...

Geospatial crop yield modeling for climate change risk transfer, impact assessment, and adaptation strategies
(2023)
Changing climate and weather patterns increase the pressure on food production systems worldwide, significantly impacting livelihoods and economies at various scales. Understanding and adapting/mitigating climate change are essential to cope with the adverse effects of climate change. Biophysical crop modeling offers a unique way to assess the pros and cons of different adaptation strategies because they integrate physical and biological principles to simulate the use and allocation of captured resources mechanistically. ...

Sustainability of traditional cocoa agroforests in Ghana
(2022)
Cocoa (Theobroma cacao L.) is an important agricultural commodity that is important to the economies of many countries in the world. Due to cocoa’s dependence on fertile forests soils, its production is a major cause of deforestation and soil degradation in producing countries. When grown in agroforestry systems it can conserve biodiversity, sequester carbon (C), and maintain soil fertility. There are many cocoa agroforests which are managed without synthetic agrochemicals. Because organic cocoa certification is now ...

Analysis of a Coupled Fluid-Elastic Interaction Problem
(2023-01)
In this thesis, a non-linear system of partial differential equations is studied, describing the motions of an elastic structure which is immersed into an incompressible viscous fluid. The displacement of the elastic structure is modelled by a Lamé system and the fluid velocity as well as the fluid pressure are described by the Navier-Stokes equations. The structure and the fluid are coupled via two boundary conditions at the interface which correspond to continuity of velocities and forces. As the elasticity is ...

Nutrition transition in Kyrgyzstan: Understanding the triple burden of malnutrition and the importance of dietary quality
(2023)
Nutrition transition, including changes in lifestyle and diet, has been taking place globally. Malnutrition is a serious public health issue responsible for the considerable portion of noncommunicable diseases (NCDs). Currently, little knowledge about nutrition transition and its relation to malnutrition exists in low and middle-income countries. Kyrgyzstan undergoes a nutrition transition with health and diet implications, especially to women. Kyrgyzstan is believed to be at the end of the ‘receding famine’ stage ...
