This master thesis investigates groundwater storage loss in the Ararat Valley’s aquifer system, driven by intensive groundwater extraction and associated with subsidence risks. Using both InSAR data and hydromechanical analysis, this research shows coherent aquifer storage changes related to localized changes in ground deformations. Non-compliance with recommended well-spacing has exacerbated stre
What drives change and continuity in welfare states? This master thesis contributes to the debate by examining the German cash-benefit “Kosten der Unterkunft und Heizung”. This cash-benefit is a component of the means-tested unemployment benefit II in Germany which was introduced by the Hartz-IV-Reform in 2005. 16 years later the case “Kosten der Unterkunft und Heizung” has undergone no major refo
This thesis examines the relationship between state-led security deployments and electoral violence during Nigeria’s federal elections from 2011 to 2023. Using a mixed-methods approach that combines subnational quantitative data with qualitative document analysis. It assesses whether the presence of military and police forces reduces or exacerbates violence. While officially justified as preventiv
This thesis investigates minority magnon excitations, firstly proposed by T. Skovhus and T. Olsen (Phys. Rev. B 110.16 (2024)), in the half-filled Hubbard model on the two-dimensional Lieb lattice. Starting from the mean-field ground state with finite Hubbard interaction, we find the splitting Hubbard bands with ferrimagnetic features and identify gapless Goldstone and gapped Higgs magnon modes wi
20-25% of semi-natural habitat per square-kilometre is required for the provision of local Nature’s Contributions to People. Farmers are key actors in reversing the severe habitat deficits in agricultural regions. Conceptually anchored in the Safe and Just Earth System Boundary Framework and the Tripartite Framework for Mitigation Pathways, this thesis combines a systematic literature review on ho
Building on recent advances of the embedded cluster approach combined with multiconfigurational theory, this work investigates the electronic states in thorium-doped CaF2 crystals. Th:CaF2 is established as a promising material for solid-state nuclear clocks, which utilize the laser-Accessible isomeric state in thorium-229. By comparing simulated absorption spectra of a library of defect configura
Migratory naive birds are thought to find the migration route from their natal site to a specific wintering area by either clock-and-compass orientation or goal area navigation. These two alternative hypotheses were tested by extensive longitudinal displacements of juvenile wheatears, hatched in northeastern Siberia, on their first autumn migration towards the wintering area in East Africa. Orient
The article demonstrates how international relations (IR) as a discipline has failed to sufficiently attend to caste and casteism as matters of crucial significance for analyzing international, transnational, and global politics. Despite ongoing initiatives to make IR scholars knowledgeable about and attuned to how issues of race and racism directly impact many of the discipline’s core areas of re
In slowly driven classical systems, work is a stochastic quantity and its probability distribution is known to satisfy the work fluctuation-dissipation relation, which states that the mean and variance of the dissipated work are linearly related. Recently, it was shown that generation of quantum coherence in the instantaneous energy eigenbasis leads to a correction to this linear relation in the s
In this paper, the local bonding structure in amorphous zinc tin oxide (a-ZTO) is probed using a combination of XANES and EXAFS techniques at the Zn and Sn K-edges to gain insight into charge carrier generation in the material. a-ZTO is prepared using two growth methods; spray pyrolysis and magnetron sputtering. It is seen that a-ZTO grown by magnetron sputtering shows no changes in the chemical e
Value-added bioproducts are linked to the expansion of lignocellulosic biorefineries based on agro-industrial waste and local economic growth. Thus, the aim of this study was to pretreat rice hull (RH), a highly recalcitrant biomass, with saturated steam and convert it to lactic acid (LA). Strategically, the individual fractions and the blend of detoxified liquor and water-insoluble solids were us
Dynamic resource management is a difficult problem in modern microservice applications. Many proposed methods rely on the availability of an analytical performance model, often based on queueing theory. Such models can always be hand-crafted, but this takes time and requires expert knowledge. Various methods have been proposed that can automatically extract models from logs or tracing data. Howeve
Aminoglycoside antibiotics are widely used to treat infectious diseases. Among them, streptomycin and kanamycin (and derivatives) are of importance to battle multidrug-resistant (MDR) Mycobacterium tuberculosis. Both drugs bind the small ribosomal subunit (30S) and inhibit protein synthesis. Genetic, structural, and biochemical studies indicate that local and long-range conformational rearrangemen
The aim of this study was to describe changes in the use of accident and emergency departments in the Copenhagen Hospital Co-operation after restricted admittance to the accident and emergency department at a large Danish university hospital, Rigshospitalet (admittance only for patients transported by ambulance or presenting with a referral from a doctor).MATERIAL AND METHODS: A retrospective stud
Segregated bimetallic nanoparticles like core-shell nanoparticles are of interest in various fields including biomedicine, catalysis, and optoelectronics. Aerosol technology is an optimal platform to control nanoparticle size, structure, and composition, which are some of the most important parameters tuning the material performance for the intended applications. Here, we develop a novel evaporato
This paper introduces a new lifting method for analyzing convergence of continuous-time distributed synchronization/consensus systems on the unit sphere. Points on the d-dimensional unit sphere are lifted to the (d+1)-dimensional Euclidean space. The consensus protocol on the unit sphere is the classical one, where agents move toward weighted averages of their neighbors in their respective tangent
Increase in wildfires has changed parts of the landscape and ecosystems of the Mediterranean region. By using the firecapes approach, this paper aims to establish a connection between wildfires as a natural phenomenon and the political dynamics surrounding land ownership, knowledge, and mitigation. Theoretically, we apply political ecology to contextualize firescapes by examining the historical pr
Antibunching effect is typically observed in individual systems possessing photoluminescence (PL) blinking and vice versa. Contrary to this common perception, absence of antibunching in strongly blinking methyl ammonium led tri-iodide (MAPbI3) perovskite crystals of sizes from tens to hundreds of nanometers regardless of the excitation power density is observed. Antibunching effect does not appear
Determining non-metallic inclusions (NMIs) are essential to engineer ultra-high-strength steel as they play decisive role on performance and critical to probe via conventional techniques. Herein, advanced Synchrotron X-ray absorption coupled with photoemission electron microscopy and first-principles calculations are employed to provide the structure, local bonding structure and electronic propert
