Thermosphere and radiation effects in forward and inverse non-gravitational force modelling
(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. <br /> Satellite orbits are perturbed by gravitational ... -
Characterization of insecticide resistance in Hemipteran crop pests with special reference to aphids and whiteflies
(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
(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
(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
(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
(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 ... -
The Importance of International Quality Standards in Negotiating Trade Agreements between the European Union and Third Countries as regards Global Trade in Agricultural Products and Food
(2023-12-14)The aim of this thesis is to assess the role of international quality standards in context of free trade agreements, taking into account international supply chains and global value chains. An intensive literature review ... -
The impact of automated, constant incomplete milking on energy balance, udder health, and subsequent performance in early lactation of dairy cows
(2023-12-14)During the first weeks of lactation, dairy cows experience a negative energy balance (NEB), because the energy supply provided by feed intake can not cover the energy needed for maintenance and rising milk production at ... -
Reduction of Gaseous Emissions from Slurry by the Application of Alkaline Additives
(2023-12-12)The agricultural sector is undergoing a profound transformation process to meet international and national regulations and laws. These are being enacted by policymakers to limit the sector's tremendous gaseous emissions ... -
Assessment of different innovative packaging strategies to maintain the quality of fresh produce
(2023-12-12)The objective of this thesis was to assess the influence of different innovative packaging strategies on typical quality parameters of fresh produce and thus to keep and even improve the resource efficiency in food supply ... -
Measuring and scaling environmentally induced dynamics of solar-induced chlorophyll fluorescence (SIF) from the ground to the aircraft
(2023-11-11)Chlorophyll fluorescence is the absorbed photosynthetically active radiation (PAR) re-emitted as a faint red glow when the photosynthetic apparatus is not able to run photochemistry. This relation that Chlorophyll fluorescence ... -
Transitions towards sustainable agriculture: The case of wheat-based production systems in Egypt
(2023-12-11)Egypt, the world's largest wheat importer, grapples with a critical challenge marked by a substantial disparity between its annual wheat production and consumption, with the latter doubling by 2050 due to a 1.94% yearly ... -
The role of transaction costs in strengthening agricultural market linkages to achieve higher welfare in Tanzania
(2023-11-24)Small-scale farmers (SSFs) have high levels of food insecurity and poor nutrition that are reflections of the still high prevalent poverty rates. Semi-subsistence smallholder farming is still predominant in many parts of ... -
Memory of past drought stress exposure effects plant responses in subsequent generations in winter wheat (Triticum aestivum L.)
(2023-11-23)Current research suggests that plants can memorize the environments experienced by their ancestors to alter their phenotypes. Parental environmental effects have been reported for the first offspring generation, and some ... -
Economics of consumer and business behavior related to environment: studies in Belarus
(2023-11-23)Environmental problems constitute a major risk to humanity. This thesis empirically analyzes the implications of consumer and business behavior related to environment on three levels: on a micro-; on a meso-; and on a ... -
Entomophagy in Myanmar: factors influencing edible insect consumption behavior
(2023-11-21)As the world population rapidly increases, food security and malnutrition are becoming ever more significant concerns, as well as challenges to achieving sustainable development. These global problems are exacerbated by ... -
Land in transition: Perceptions, narratives, and the governance of natural forest regrowth on abandoned land in Southwest Europe
(2023-11-21)Agricultural land abandonment is a widespread land use change in some regions of Europe. This change is driven by a complex interplay of ecological, socio-economic, and political factors, with rural depopulation as an ... -
Genotype-dependent phenotypic variation for agronomic traits, seed composition, and root architecture of Chilean Quinoa (Chenopodium quinoa Willd.)
(2023-11-20)Today, climate change is one of the biggest challenges facing agriculture practices, and it has significant implications for the sustainable provision of nutritious food in sufficient amounts. To meet such challenges, there ... -
Lignine aus Low-Input-Pflanzen: Einfluss von Biomasse, Vorbehandlung und Aufschlussparametern auf Struktur und Antioxidanz
(2023-10-31)Lignin ist ein aromatisches Biopolymer, das in den Zellwänden von Pflanzen vorkommt. Es ist hauptsächlich aus drei sogenannten Monolignolen (<em>p</em>-Hydroxyphenyl (H), Guajakol (G) und Syringol (S)) aufgebaut, die über ... -
Identification and characterization of evolutionarily conserved inositol pyrophosphate phosphohydrolases in plants
(2023-10-27)Inositol phosphates (InsPs), phosphate esters of <em>myo</em>-inositol, are cellular regulators with critical roles in a wide range of cellular processes in eukaryotes. Members of the subgroup containing at least one ...
