Validation of a generalized model for the description of polycrystalline exchange-biased magnetic thin films
(2022)
Applications based on nano- and microscaled systems have become indispensable in many aspects in everyday life, industry, research and medicine. In this regard, thin film technology plays a crucial role with the physical properties of solids changing significantly when they are reduced to thin layers with thicknesses in the nanometer range. In this regime, a solid’s microstructure as well as boundary and surface effects start to dominate. A prominent example is the exchange bias effect, which results due to the ...

Land tenure in a changing climate
(2023)
Climate change and extreme weather have far-reaching impacts on agriculture. They do not only affect agricultural production, but also fundamental assets that shape agricultural livelihoods. In this dissertation, I study the relation of weather and climate with agricultural land tenure in low- and middle-income countries. Secure access to land is of vital importance for farmers, but insecure tenure is a reality for millions of farmers around the globe. They are unsure whether they will be able to continue farming ...

Consequences of Deep Rolling at Elevated Temperature on Near-Surface and Fatigue Properties of High-Manganese TWIP Steel X40MnCrAl19-2
(2021-11-05)
Due to pronounced work-hardening induced by the complex interplay of deformation mechanisms such as dislocation slip, twinning and/or martensitic phase transformation, high-manganese steels represent a class of materials well-suited for mechanical surface treatment. In the present study, the fatigue behavior of a high-mangsanese steel showing twinning-induced plasticity (TWIP) effect at room temperature (RT) was investigated after deep rolling at 550 °C. Results are compared to a former study discussing the behavior ...

Taste masking in vegan food processing with natural substitutes
(2022-12-29)
Climate change, sustainability issues, increased risks of meat diet on both ecology and human health cause changes in the eating habits of individuals. Plant-based foods supply protein sources with health-promoting compounds. The bitterness of plant-based foods is a challenge for both food manufacturers and consumers. So far, artificial taste blockers, salt, sugar, and fat have been applied to mask the bitterness of plant-based products. However, people are conscious of "clean labelling " and "natural " ingredients ...

The effects of weather factors on titrating acids accumulation in sweet cherry fruits
(2022-12-29)
During the fruit formation, the weather conditions have a decisive influence on the organic acids accumulation. In the context of global climate change, this issue has become new. The study of the titrated acids content in sweet cherry fruits was carried out for 12 years. Cherry fruits of three ripening groups were selected for the study. The average and strong correlation dependence between 11 weather factors and the titrated acids content for the sweet cherries varieties of early, middle, late ripening periods were ...

Design, implementation and application of a generic framework for integrated regional land-use modeling
(2008-02-19)
Land use is a crucial link between human activities and the natural environment and one of the main driving forces of global environmental change. Large parts of the terrestrial land surface are used for agriculture, forestry, settlements and infrastructure. Given the importance of land use, it is essential to understand the multitude of influential factors and resulting land use patterns. An essential methodology to study and quantify such interactions is provided by the adoption of land-use models. By the application ...

Ein klimaneutrales Kassel bis 2030: Handlungsleitfaden im Bereich Naturschutz
(2023)
2019 beschloss die Stadtverordnetenversammlung Kassel, die Stadt bis 2030 klimaneutral zu machen (StaVo 2019a); dafür wurde als Beratungsgremium der Klimaschutzrat eingerichtet (StaVo 2019b). In der Regionalgruppe Kassel der Scientists for Future wurde zur Unterstützung ein Forschungsprojekt initiiert, um für dieses Ziel einen Handlungsleitfaden zu entwickeln. Sinnvollerweise enthielt der Beschluss zum Klimaschutzrat auch die Einrichtung einer Unterarbeitsgruppe Naturschutz und Biodiversität, außer den üblichen Themen ...

The Sundarbans in Bangladesh
(2019)
Bangladesh is an agricultural-based country. Agriculture contributes 42.70% (BER) in the labor market through 4 categories namely crops, fisheries, livestock, and forestry. Forestry has the most significant role in renovation of infrastructures and balancing the natural environment. Due to human and natural induced threats, the forest resources are in danger and currently, the percentage of forest in Bangladesh is 13.22 % (BER). The sector is still mistreated on the basis of compared to the other three parts of ...

Land degradation and the upper hand of sustainable agricultural intensification in sub-Saharan Africa - A systematic review
(2024-05-13)
Sub-Saharan Africa (SSA) faces severe land degradation, driven by a combination of human and natural factors. Deforestation, inadequate land management practices, and unsustainable farming methods are the primary causes. The historical trends reveal the impact of soil erosion and nutrient depletion on 70% of the soil and 65% of its total land area. Unchecked degradation poses a critical threat to economic growth and poverty reduction initiatives. The region's food security is intricately linked to the complex interplay ...
