Investment in health within the agriculture, water, sanitation and hygiene nexus for rural households in Bangladesh
(2018-02-16)Water, sanitation and hygiene (WASH) related burden of disease is one of the most important aspects of human capital formation. As WASH is a system issue, it needs to be investigated with many other complementary factors ... -
Application of proximal sensing techniques for epidemiological investigations of Fusarium head blight in wheat under field and controlled conditions
(2018-02-13)Sensors can provide valuable insight into studying the physiological disorder due to plant pathogens. <em>Fusarium</em> head blight (FHB) influences the optical properties of wheat (<em>Triticum aestivum L.</em>) at canopy ... -
Interventionsstudie zur Rolle von Isoflavonen im Fettstoffwechsel gesunder postmenopausaler Frauen
(2018-03-19)In postmenopausalen Frauen (PMF) gehen hormonelle Veränderungen mit charakteristischen Wechseljahrsbeschwerden und Veränderungen der Körperfettverteilung sowie der Lipoprotein- und Serumlipidkonzentrationen einher und ... -
Occasional direct-seeding of grain legumes in Organic Agriculture in Germany and Brazil: fertilisation with P and S & weed control with natural herbicides
(2018-02-13)The aim of this work was to test strategies, which improve nutrient supply and weed control in occasional direct-seeded (DS) grain legumes in Organic Agriculture. The effect of intra-row fertilisation of rock phosphate ... -
Analyzing trade-offs between ecosystem services in multi-functional landscapes
(2018-03-06)The urgent need to preserve multiple ecosystem services is one of the key challenges in natural resource management globally. A management decision can cause undesired con- sequences when a decision is made without a ... -
Reactions between nitrite and soil organic matter and their role in nitrogen trace gas emissions and nitrogen retention in soil
(2018-01-22)As a key intermediate of both nitrification and denitrification, nitrite (NO<sub>2</sub><sup>-</sup>) is highly chemically reactive to soil organic matter (SOM), and it was proved previously that considerable amounts of ... -
Identification and characterization of a cystatin-like effector protein from beet cyst nematode Heterodera schachtii and its role in plant-nematode interaction
(2018-01-18)Sedentary cyst nematodes are of high economic interest as they can cause substantial yield losses in important crop plants. Due to their complex soil-based life cycle and severe restrictions on the application of nematicides ... -
Effects on Aerobic Processes at Silage Faces
(2018-01-31)In animal nutrition, one of the most important and indispensable requirements is high quality of feed. Especially the staple feed, which builds the basic feed for animals’ rations, has to fulfill high quality criteria. In ... -
MicroRNA-424/503 cluster involvement in regulation of bovine granulosa cell function and oocyte maturation
(2018-01-11)Several microRNA (miRNA) clusters are known to be differentially regulated during follicular development. Previously, it was reported that the miR-424/503 cluster was highly abundant in bovine granulosa cells (bGCs) of ... -
Environmental behavior of cesium and strontium in agricultural and forest soil
(2018-01-11)Radionuclides are critical soil contaminants, particularly cesium (Cs-137) and strontium (Sr-90) are harmful due to their high radiotoxicity and metabolic similarity to major soil nutrients (e.g. K<sup>+</sup>, Ca<sup>2+</sup>) ... -
Dynamics of nitrogen and phosphorus under the impact of climate change and agricultural land use in the West African Sudan Savannah
(2018-01-16)Changing climate and agricultural land-use dynamics seriously challenge the future of cropping in the West African Dry Savannah, and, in turn, the livelihoods and food security of rural populations. Current production ... -
Lucerne silage for high yielding dairy cows: evaluation of the nutritional value using chemical and in vivo methods
(2018-02-07)Lucerne has a high yield potential and can provide ruminants with significant amounts of energy and protein as well as having excellent structural properties. This thesis focussed on the response (dry matter intake (DMI), ... -
Analysis of the role of polygalacturonase inhibiting proteins in the interaction between plants and nematodes
(2018-01-04)Plant-parasitic nematodes (PPNs) are a great threat to crops, causing billions of dollars of losses worldwide. Cyst nematodes and root-knot nematodes belong to a small group of sedentary endoparasitic PPNs that parasitize ... -
Determinants of incentive-based forest governance in the Amazon: Evidence from Ecuador, Peru, and Brazil
(2018-02-07)Command-and-control policies are often criticized as insufficient to tackle tropical deforestation. Over the past two decades, both academics and policy-makers have promoted incentive-based policies, such as payments for ... -
Incremental Map Building with Markov Random Fields and its Evaluation
(2018-01-04)This thesis presents a novel occupancy grid mapping approach which takes the dependencies of neighboring grid cells into account. The grid maps are estimated based on a compact environment representation which is derived ... -
Water Quality in Multipurpose Water Systems, Sanitation, Hygiene and Health Outcomes in Ghana
(2018-03-29)This thesis examines the interlinkages between water quality, water use, sanitation and hygiene practices, other household characteristics and health outcomes in the context of multipurpose water systems in Ghana. ... -
Subcellular glutathione homeostasis and characterisation of glutathione transport across the plasma membrane in Arabidopsis thaliana
(2017-12-22)Challenging environmental conditions are known to alter glutathione homeostasis, notably by inducing the accumulation of oxidized glutathione, an effect that may be influential in the perception or transduction of stress ... -
Epigenetic and exosome-mediated cell-cell communication in follicular cells and preimplantation embryos
(2017-12-21)Follicular cells and preimplantation embryos communication with their in vivo or in vitro environments via mechanisms including cell adhesion and extracellular vesicles is crucially essential for normal oocyte and embryo ... -
