Experimental analyses of individual sustainable choices
(2023)
This dissertation complements the aforementioned studies by considering choice and allocation experiments which allow to directly examine how individuals choose between sustainable prod-ucts and their conventional counterparts. It particularly examines how different experimental designs and interventions causally affect choices between sustainable electricity contracts and investments over their conventional counterparts and provides guidance on how to analyze these choices using a Monte Carlo experiment.

Joining of Contact Pins and Conductive Compounds via Injection Molding – Influence of the Flow Situation on the Electrical Contact Resistance
(2020-04-09)
While a lot of research can be found in the field of bulk resistance of carbon filled polymers, comparatively few papers focus on contact resistance between compound and metal contacts. Due to that small number of researches that deal with contact resistances, studies of the influence of injection molding conditions and parameters on the contact resistance are also very rare. In contradiction to that, these influences on bulk resistance have been studied. The objective of this work was to investigate the electrical ...

Effects of aging on the stress-induced martensitic transformation and cyclic superelastic properties in Co-Ni-Ga shape memory alloy single crystals under compression
(2022)
Co-Ni-Ga shape memory alloys attracted scientific attention as promising candidate materials for damping applications at elevated temperatures, owing to excellent superelastic properties featuring a fully reversible stress-strain response up to temperatures as high as 500 °C. In the present work, the effect of aging treatments conducted in a wide range of aging temperatures and times, i.e. at 300–400 °C for 0.25–8.5 h, was investigated. It is shown that critical features of the martensitic transformation are strongly ...

Microstructure of an additively manufactured Ti-Ta-Al alloy using novel pre-alloyed powder feedstock material
(2023-05-01)
Binary Ti-Ta and ternary Ti-Ta-Al alloys attracted considerable attention as new potential biomaterials and/or high-temperature shape memory alloys. However, conventional forming and manufacturing technologies of refractory based titanium alloys are difficult and cost-intensive, especially when complex shapes are required. Recently, additive manufacturing (AM) emerged as a suitable alternative and several studies exploited elemental powder mixing approaches to obtain a desired alloy and subsequently use it for complex ...

Von postkolonialen, dekolonialen und indigenen Studien lernen: Ein Scoping Review
(Verlag Julius Klinkhardt, 2023)
Der vorliegende Beitrag stellt anhand eines Scoping Review dar, wie postkoloniale, dekoloniale und indigene Studien in den Disability Studies rezipiert werden. Hierzu führt er zunächst in den Diskurs über die Dekolonisierung der Disability Studies ein (1) und reflektiert die Kolonialisierung des Wissens auch anhand unseres Forschungsdesigns (2) in Form eines Scoping Reviews als Herangehensweise, mit Literatur umzugehen. Danach stellen wir erste Ergebnisse dar (3) und diskutieren diese (4).

Making transdisciplinarity happen: Phase 0, or before the beginning
(2022-06-21)
Both within science and society, transdisciplinary approaches are increasingly employed to address today’s sustainability challenges. Often transdisciplinary research processes are structured in three core phases: a) problem identification and formation of a common research object; b) co-production of solution-oriented and transferable knowledge; c) embedding co-produced knowledge through transdisciplinary reintegration. In all phases of this ideal-typical model, the involvement of non-academic actors is essential ...

Diffusion of Material Flow Cost Accounting and its Contribution to Sustainable Development
(2022)
This thesis aims to analyze how further take-up of Material Flow Cost Accounting (MFCA) in practice can be encouraged to support sustainable development. To achieve the aim of the thesis, three studies on MFCA are conducted at multiple levels. The first study provides a better understanding of MFCA application at the corporate level in developing countries, which are characterized by rapid structure transformation leading to serious environmental problems. The second study considers the contextual and transformational ...

Assessment of the variation of marbling and intramuscular fat content of beef, and validation of possible factors to increase sensory beef quality
(2021-11)
This thesis focuses on the intramuscular fat content (IMF) or the marbling of beef as main parameters of sensory beef quality. The aim is to identify the high variability of these traits and to verify possible influences such as genetics, age, gender and feeding strategies to increase marbling.
The first part of this research focuses on the variation of quality traits within a genetically homogeneous line of an endangered German beef cattle breed “Rotes Höhenvieh” (RHV). The intramuscular fat content of beef samples ...
