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 ...

Bewertung von Eigenspannungen nach dem Laserstrahlhärten von komplex geformten Komponenten und additiv gefertigten Bauteilen
(2021)
Die Laserstrahlbearbeitung hat sich im Laufe der letzten Jahre zu einem wichtigen Forschungsschwerpunkt in industrieller und akademischer Hinsicht entwickelt. Neben der Erschließung neuer Anwendungsgebiete durch den Vorteil einer hohen Bearbeitungsflexibilität überzeugt die laserbasierte Materialbearbeitung vor allem durch einen lokal beeinflussbaren Energieeintrag. Jedoch sind derzeit mit zunehmender geometrischer Komplexität und Bauteilgröße nur begrenzte Tiefenwirkungen der gewünschten Druckeigenspannungen ...

Community-Based Associations and Rural Development in Rwanda: A Local Perspective on the Contribution of Social Capital to Human Capabilities
(2022)
The post-World War II political discourse around development has stimulated academic debates in recent decades. While some of these debates simply aim to transform the development mainstream, many others among the post-colonial thinkers are more critical of and even reject mainstream development ideologies. Despite the valuable academic debates, most development practitioners seem to have remained unresponsive to some of the allegations. Their concept is incorporated in much of the contemporary political narratives ...

Generalized Involutive Bases and Their Induced Free Resolutions
(2022-05)
In this thesis, we generalize several types of involutive and marked bases for ideals in quotient rings of commutative polynomial rings. We apply these new types of bases to the analysis of infinite free resolutions and of Hilbert schemes defined over certain types of quotient rings. We are mostly concerned with Pommaret and Janet bases; the marked bases we consider are marked over monomial submodules that are quasi-stable, i.e., that possess finite Pommaret bases.
Involutive bases of the types we consider induce ...

A Language Ecosystem for Modeling Microservice Architecture
(2022)
The ongoing digital transformation of our economy and society poses significant challenges towards modern software systems. Application areas like Smart Cities and Industry 4.0 set high requirements on software quality attributes like scalability and reliability. At the same time, IT companies face an ever-growing demand in flexibility and continuous improvements of delivery cycles. Microservice Architecture (MSA) is a novel approach to the realization of software architectures that aims to foster their scalability, ...

Denaturation mechanism of whey protein by using the hot extrusion technology
(2022-02)
Milk proteins are one of the heat-sensitive nutritional components, especially whey proteins changing their structure through thermal treatment, consequently denaturizing and aggregating. The transformation of native whey proteins structure in presence of shear stress resulted in the microparticulation, which affected the functional properties. Many authors investigated these parameters with different conditions; however, understanding the combination of relevant parameters of the microparticulation process of whey ...

Implementation of targettarget-orientated approaches in antibiotic and homeopathic treatment of acute bovine clinical mastitis in dairy practice
(2022-07)
Diese kumulative Dissertation hatte das übergeordnete Ziel Rahmenbedingungen (Voraussetzungen) für einen hohen Behandlungserfolg bei der antibiotischen und homöopathischen Mastitistherapie auf Milchviehbetrieben zu identifizieren sowie mögliche Optionen zur Erhöhung der Heilungsraten zu ermitteln. Darüber hinaus wurde die Steigerung des Behandlungserfolges unter der Maßgabe eines reduzierten Antibiotikaverbrauchs untersucht.

Patterns of Practice - Interdisciplinary Negotiation of Cultural Complexity through Practice-Based Methods in Informatics
(2022)
Following the principle of knowing through making, this thesis discusses development and application of a practice-based methodology for construction of digital artefacts within
cultural contexts. It addresses the epistemological diversity and complexity inhering within interdisciplinary projects, suggesting methodological devices able to navigate the variegated disciplinary landscape present within respective development projects. The conceptual pair complexity/complication acts as theoretical point of reference ...

Using Optical Satellite Imagery to Monitor and Understand Agricultural Land-cover Change
(2020-06)
The activities of humans have transformed the earth over the last decades. The transformation is estimated to increase further in response to the growing world population. This has caused many countries to devise means to utilize resources sustainably. Bio-economy is seen as a means to reduce the high reliance on fossil materials and ensure the provision of raw materials, energy and food to the increasing world population in a sustainable manner. However, the rising demands for biomass to produce bioenergy have relied ...

The effect of physical activity on motor cognition in elderly people
(2021-12)
For the presented doctoral thesis, four cross-sectional studies and a longitudinal study were conducted to examine the correspondence between physical activity and motor cognition in older adults. A total of six hypotheses were tested. Forty older adults between 65 and 80 years of age (subdivided into an active and an inactive subgroup based on Freiburg Physical Activity Questionnaire) and 20 sports students as a control group participated in the cross-sectional studies. Eighty-two seniors aged between 65 and 80 years ...
