Enhancing Nitrogen Fertilisation Efficiency by Developing Novel Nitrification Inhibitors for a Greener Agriculture
Yildirim, Sibel Cansu (2024-03-25)Nitrogen fertilization in agriculture has serious environmental consequences, including production of the greenhouse gas nitrous oxide (N2O), pollution of groundwater with nitrate (NO3-), ... -
Ultrasound-assisted enzymatic maceration and valorization of by-products: A contribution to sustainable production of berry juices
Nemetz, Nicole Jasmin (2024-03-06)Red berry juice, rich in secondary plant metabolites such as anthocyanins, represents a good alternative to the consumption of red berries. According to the German Association of Nutrition, a consumption of five portions ... -
Analytical and nutritional evaluation of rye grain in diets for growing pigs
Schmitz, Klara Theresa (2024-02-22)Climate change and increasing consumer awareness of environmental and animal welfare issues are constantly challenging the animal nutrition sector to adapt and find improved solutions that are resource efficient, meet the ... -
Detection and Attribution of Spatiotemporal Trends of Climatic Disaster Mortality in Nepal
Chapagain, Dipesh (2024-02-16)The socioeconomic impacts of climatic disasters are increasing globally. Some studies have argued that this increasing trend results from the growing population and assets exposed to hazardous events. Other studies have ... -
Acceptance of innovations for sustainable food production: A consumer and farmer perspective on the use of soil-microbes
Ploll, Ursula (2024-02-05)In alignment with a transition to sustainable agriculture, alternatives for conventional harmful agricultural inputs are needed. Researchers in the field of plant production have emphasised that beneficial soil-microbes ... -
Thermosphere and radiation effects in forward and inverse non-gravitational force modelling
Vielberg, Kristin (2024-02-01)Precise non-gravitational satellite force models are crucial for various space-based applications, thus contributing to a better understanding of the Earth system.
Satellite orbits are perturbed by gravitational ... -
Characterization of insecticide resistance in Hemipteran crop pests with special reference to aphids and whiteflies
Müller, Viola (2024-01-26)Agriculture faces enormous challenges: In addition to the increasing demand for agricultural products with less available agricultural landscapes, there is a need to protect the environment and biodiversity and to minimize ... -
Temperature-dependent development of porcine skeletal muscle cells in an in-vitro model
Metzger, Katharina (2024-01-25)Satellite cells are quiescent myogenic stem cells and it is possible to derive an in-vitro model of these cells. This in-vitro model can be used to represent myogenesis using proliferating myoblasts and differentiating ... -
Root growth of sole and mixed cover crops in organic farming
Kemper, Roman (2024-01-23)Cover crops are an important tool in arable farming systems. They provide many different agroecosystem services. For many of these functions, such as nutrient uptake, erosion prevention and soil structure formation, the ... -
Market expectations, public information and uncertainty resolution in agricultural commodity and equity markets
Cao, Nguyen Que An (2023-12-14)The Efficient Market Hypothesis (EMH) states that price movements result from changes in market expectations when new information becomes available. This thesis focuses on such revisions of expectations around the releases ... -
Mapping and Interpolation of Tropospheric Ozone Data with Machine Learning Methods
Betancourt, Clara (2023-12-14)Tropospheric ozone is a toxic trace gas in the atmosphere. It threatens human health, damages crops and vegetation, and it is a short-lived climate forcer. Ozone is a secondary air pollutant that undergoes multiple physical ... -
