Biochemical Characterization of Microtubule-Associated Serine/Threonine Kinases
(2023)
The association of human microtubule-associated serine/threonine (MAST) kinases with different diseases, such as neurodevelopmental disorders and cancer, leads to hight interest in understanding the function of these understudied kinases. This PhD thesis provides the first consolidated biochemical analysis of three different human MAST kinases (MAST1-3) and the Drosophila melanogaster homologue drop out protein (DOP).

Evaluation of efficacy of homeopathic and antibiotic treatment in scientific research and practice with focus on bovine mastitis
(2024)
The use of homeopathy and antibiotics in treatment have the same goal: to cure a diseased individual. The first choice should be the most effective treatment and only a repeated treatment success will justify its use. If the chosen treatment is not effective, unnecessary suffering of diseased animals, spreading of disease or chronification of mastitis will be the result. Additionally, in case of antibiotic use, an ineffective use will select and promote the prevalence of multi-resistant bacteria in the environment, ...

Modeling analysis of 21st century climate change projections and their impacts on the hydrology of the Karaj-Jajrood basin, Iran
(2023-12)
Two main rivers, Karaj and Jajrood which provide metropolitan Tehrans’ water, flow in Alborz and Tehran province, respectively. In the last decades, the impact of climate change on temperature and precipitation is tangible in these two provinces. For the Karaj-Jajrood basin, during the period 2003-2012, the minimum temperature increased by 1°C, the maximum temperature by 0.6°C and precipitation decreased by -7%, relative to the average of 1972-2012.
To assess climate change impacts in the region, the Statistical ...

Effektive Integration von heterogenen Produktkatalogen im schnelllebigen Umfeld des E-Commerce
(2023)
Online-Marktplätze generieren von Jahr zu Jahr einen größeren Anteil des Einzelhandelsumsatzes. Ein wichtiger Faktor für den Erfolg von Online-Marktplätzen ist die korrekte Darstellung der Produktdaten für ihre Kunden. Diese Daten werden häufig von Zulieferern in Form von Produktkatalogen zur Verfügung gestellt, die in den Online-Marktplatz integriert werden müssen. Um dies zu erreichen, sind insbesondere kleine und mittelständische Unternehmen häufig auf aufwändige manuelle Arbeitsschritte bei der Datenintegration ...

Fostering sustainable consumption through communication: Consumers’ appreciation of biodiversity-friendly pasture-based cattle husbandry
(2024-01)
Considering dramatic environmental changes, there is an evident necessity of a transition to more sustainable animal production that caters to societal demand for ethical production and consumption. The slow but steady shift in consumer demand for animal-friendly, environmentally, and socially re-sponsible animal products has been well documented over the past years. The overarching goal of this dissertation is to provide insights regarding consumer perceptions, acceptance, preferences and com-munication of ...
Dissertation
Reporting Power
(2024)
An eclectic genealogy (Foucault, 1977) that reconstructs the previous understanding and emergence of a ‘taken for granted’ global practice: the practice of suspicious activity reporting. A governance practice whereby financial institutions worldwide document and report the conduct of consumers deemed suspicious. At the center of this practice is a material artefact, a multipage fillable form called the Suspicious Activity Report. Following Actor-Network Theory (Latour, 1987), the form also serves as the centerpiece ...

Dynamics of Norms in Decision-Making
(2024-01)
So far, there is a lack of understanding how norms change. The aim of the present dissertation was twofold: (1) addressing differences between change processes of different types of norms and (2) focusing more particularly on how norms are internalized. To study norm dynamics, a multi-method approach was chosen, combining theory, social simulation, and experimental research. In the theoretical contribution, a psychologically grounded conceptual model of norm change and decision-making was presented. Based on a refined ...

A Unifying Theory for Runge-Kutta-like Time Integrators: Convergence and Stability
(2024)
The work deals with two major topics concerning the numerical analysis of Runge-Kutta-like (RK-like) methods, namely their stability and order of convergence. RK-like methods differ from additive RK methods in that their coefficients are allowed to depend on the solution and the step size. As a result of this, we also refer to them as non-standard additive RK (NSARK) methods. We motivate and introduce modified Patankar (MP) schemes as a subclass of NSARK methods and emphasize their importance. The first major part ...

Immobilization of Neodymium Complexes on Semiconductor Surfaces and Processing of GaAs-based Photonic Crystals
(2024)
Lanthanide ion luminescence exhibits characteristic narrow emission bands ranging from VIS to NIR along with relatively long emission lifetimes which makes them attractive for applications in lighting, sensing, and display technologies. The focus of this dissertation lies on the optical characterization of newly synthesized neodymium complexes bearing phosphonate ester ligands and the fabrication of photonic crystal (PhC) cavities. Micro-photoluminescence (PL) spectroscopy is used to investigate the NIR emission bands ...

New Approaches for the Quantification of Metabolic and Economic Trade-Offs Related to the Health and Longevity of Individual Dairy Cows
(2024)
Background: In dairy cows, negative associations between the genetic merit for milk yield and fitness traits as well as a lack of success in lowering the prevalence of production diseases have been noticed over the past 30 years across different production methods, herd sizes and countries. On the other hand, individual farms and individual cows within a farm succeed in simultaneously achieving high performance, low prevalence and high profitability, while others cannot cope with these challenges. Differences in milk ...
