Structural transformation and labour market development in Sub-Saharan Africa: Evidence from Ghana and Nigeria
(2023-09-13)The thesis examines the changing economic and employment structure in Sub-Saharan Africa by focusing on Ghana and Nigeria. It is structured into an introduction and four main chapters, each answering specific research ... -
Effect of organic soil amendments on increasing soil N retention and reducing N losses from agricultural soils
(2023-09-01)In the course of my doctoral studies, I actively engaged in my advisor's research projects, which involved participating in the establishment of lysimeter experiments and conducting research on isotopes. My research findings ... -
Linking land use-land cover change with annual and perennial plant growth models for the spatio-temporal explicit simulation of ecosystem services: A case study in a savanna region of Ghana
(2023-08-30)Many West African economies have been experiencing fast growth over recent decades. At the same time, their landscapes are also experiencing one of the fastest changes in the world, and the pace has accelerated over recent ... -
Impact of dietary interventions on metabolism and the gut-brain axis in adults with metabolic syndrome traits
(2023-08-09)In recent decades, the incidence of obesity and obesity-associated comorbidities such as the metabolic syndrome has exponentially increased in both developed and developing counties. It is widely accepted that inadequate ... -
Effects of nutritive antioxidants on bone during immobility
(2023-07-27)Age and disease related inactivity in older people and inactivity during space flight and in ground-based analogs, such as 6° head-down tilt bed rest (HDBR) are associated with bone loss. This bone loss is mainly induced ... -
Adjuvant-induced alterations of cuticular waxes and their consequences for mechanisms of drought stress resistance
(2023-07-26)The most important function of the cuticular waxes is the shielding of the plant from uncontrolled water loss as well as from pathogens, UV radiation and pollutants. Penetrating agrochemicals are also effectively shielded ... -
The role of inositol pyrophosphates in the regulation of plant stress responses
(2023-07-13)Inositol polyphosphates (InsPs) have been described as important messengers in eukaryotic cells. InsPs with one or more diphospho groups are also termed inositol pyrophosphates (PP-InsPs), which gained special attention ... -
Georeferencing of Mobile Mapping Data
(2023-07-06)One of the main tasks in Engineering Geodesy is the measurement and monitoring of geometry related phenomena on local or regional scales. Examples are the generation of high-resolution 3D city models, as they are needed ... -
Assessing emerging technologies for sustainability transitions: An analysis from a technology, company and ecosystem perspective
(2023-06-29)Understanding the role of technological innovations has always been a central concern of strategic management research. Specifically, to address the current challenges of the 21st century, such as climate change ... -
Strategies for the Empirical Determination of the Stochastic Properties of Terrestrial Laser Scans
(2023-06-28)Terrestrial laser scanners (TLS) are suitable for the surface approximation of objects and their geometric changes due to the temporally and spatially high-frequent data acquisition. However, precise geodetic engineering ... -
Soil Erosion under Spatially Heterogeneous Field Conditions: Experimental Analysis and Dynamic Modeling
(2023-06-28)Soil erosion is a significant problem for most of the agroecosystems worldwide, as it is one of the primary causes of soil degradation caused by a loss of the topsoil layer. Most of the existing soil erosion models provide ... -
Conditional cash transfers, migration, and child welfare in rural El Salvador
(2023-06-23)Governments and households take various initiatives to protect and improve children’s welfare. The present research explores how effective some of those initiatives are in protecting child nutrition, increasing schooling, ... -
Improving nitrogen retention in soils treated with Pig and cattle slurry through the use of organic soil amendments
(2023-06-21)Animal slurry has recently experienced a renaissance as organic nitrogen (N) fertilizer because, on the one hand, sustainable organic farming is receiving growing attention in order to protect the environment and, on the ... -
Nutzung der regenerativen Energiequelle „Abluftreinigungsanlage“ für das Kühlen und Heizen von Tierställen: Fallstudienuntersuchungen
(2023-04)Ziel des Forschungsprojektes „Nutzung der regenerativen Energiequelle Abluftreinigungsanlage zum Kühlen und Heizen von Tierställen – Fallstudienuntersuchung“ (EnergARA) war es, durch Langzeituntersuchungen in der Praxis ... -
Characterization of porcine milk exosomes from different stages of lactation
(2023-05-11)Exosomes are membranous vesicles considered major players in cell-cell communication. Milk provides adequate nutrition, transfers immunity, and promotes neonate development, and milk exosomes are suggested to have a key ... -
The effect of information provision on attitude, intention, and food choice behaviour: Four experimental studies
(2023-05-09)The agricultural and food sector in Germany is facing a number of challenges. Consumers are increasingly dissatisfied with contemporary livestock production and, in addition, livestock farming accounts for a substantial ... -
Improvement of Piglet Rearing's Energy Efficiency and Sustainability Using Air-to-Air Heat Exchangers: A Two-Year Case Study
(2023-02-11)Pig farming in mechanically ventilated barns requires much electricity for ventilation or exhaust air purification. Furthermore, thermal energy is needed to fulfill the animals’ temperature requirements, especially in ... -
Glucocorticoids in relation to behavior, morphology, and physiology as proxy indicators for the assessment of animal welfare: A systematic mapping review
(2023-01-06)Translating theoretical concepts of animal welfare into quantitative assessment protocols is an ongoing challenge. Glucocorticoids (GCs) are frequently used as physiological measure in welfare assessment. The interpretation ... -
Recovering from Financial Implications of Flood Impacts: The Role of Risk Transfer in the West African Context
(2022-07-10)In many West African river basins, households regularly experience floods and the associated impacts. In the absence of widely accessible formal risk transfer mechanisms (e.g., insurance), households often have to cope ... -
Differences among domestic chicken breeds in tonic immobility responses as a measure of fearfulness
(2023-04-04)Background: One priority for animal welfare is for animals to experience less fear, especially during human contact. For domestic animals, breeds that are less fearful may provide genetic resources to develop strains with ...
