The Relationship between the Resource Curse and Genuine Savings as an Indicator for Weak Sustainability: Theoretical Background and Empirical Evidence
(2017-07-11)This dissertation deals with the relationship between the Resource Curse (RC) – the empirically proven paradox that countries with abundant natural resources often show slower economic growth – and a measure for the ... -
Systems biology analysis of meat quality in Duroc × Pietrain pigs based on integrated omics approaches
(2017-07-03)Water holding capacity and drip loss are important commercially interesting meat quality parameters with low heritabilities and complex genetic and metabolic background. The aim of this thesis was the application of different ... -
The Impact of Public Policies on Deforestation in the Brazilian Amazon
(2017-07-03)Between 2000 and 2012, 2.3m sq. kilometers of tree cover, equivalent to 6.4 times the size of Germany, were lost globally due to land cover change. Forest loss often comes with significant social and environmental costs. ... -
Identification and characterization of effector proteins of the beet cyst nematode Heterodera schachtii
(2017-05-16)Plant parasitic nematodes (PPN) are considered as economically important pests of a wide range of plants including ornamentals, vegetables, and fruit trees. The beet cyst nematode <em>Heterodera schachtii</em> causes massive ... -
Conceptualizing the concept of disaster resilience: a hybrid approach in the context of earthquake hazard: case study of Tehran City, Iran
(2017-05-19)From the natural perspective, disaster resilience is defined as the ability of a system or community to resist, mitigate, respond, and recover from the effects of hazards in efficient and timely manner. How urban communities ... -
Binding and mobilization of pharmaceuticals in wastewater-irrigated soils and sediments of the Mezquital Valley, Mexico
(2017-05-16)The irrigation of crop fields with treated or untreated wastewater has been an ancient practice in many cities around the world and is still a common practice nowadays. In doing so, wastewater is disposed and at the same ... -
Immediate and protracted transcriptional response of muscle tissue to transient variation of incubation temperature in broilers
(2017-06-09)Eggshell temperature is a critical factor, which can possibly influence immediate and/or long-term gene transcription and expression. Manipulation of temperature (low 36.8°C and high 38.8°C relative to control 37.8 °C) at ... -
Managing seasonal soil nitrogen dynamics in inland valleys of the West African savanna zone
(2017-05-16)Most cropping systems in the Dry Savanna agro-ecological zone of West Africa qualify as low-input systems. Nitrogen is the most limiting nutrient element and the prevailing low-input systems rely mainly on the provision ... -
Einfluss von Vitamin D auf das klinische Outcome von Patienten mit chronischer Herzinsuffizienz
(2017-07-11)Hintergrund: Es hat sich gezeigt, dass eine Vitamin D-Mangel bei Patienten mit chroni-scher Herzinsuffizienz weitverbreitet ist. Zudem dichten sich die Hinweise, das Vitamin D einen günstigen Einfluss auf kardiovaskuläre ... -
Grazing behavior of two Holstein dairy cow strains under organic farming conditions in Switzerland
(2017-04-11)The aim of the thesis was to test if concentrate supplementation is required in an organic, pasture-based feeding system and if concentrate supplementation influences grazing behavior. The study consisted of two trials, ... -
The role of cellular and extracellular MicroRNAs in bovine follicular development and as potential indicators of early pregnancy
(2017-04-06)MicroRNAs (miRNAs), a class of short non-coding RNA molecules, emerged as major regulators of ~60% of all protein encoding genes. These molecules play an important role in mammalian follicular growth and embryonic development ... -
Drying front formation in topmost soil layers as evaporative restraint: Non-invasive monitoring by magnetic resonance and numerical simulation
(2017-04-04)Prediction of soil moisture changes on large scales is of various interests with regard to water resources management. Within this PhD work, different Magnetic Resonance (MR) concepts/apparatus and sequences were applied ... -
Subcellular localization of Glutathione peroxidase-like enzymes (GPXLs) in Arabidopsis thaliana and characterization of GPXL3 deficient mutants
(2017-03-27)A common feature of plants being exposed to diverse forms of environmental stress is the increased formation of reactive oxygen species (ROS) in both photosynthesis and respiration. Formation of ROS, however, is not ... -
Influence of nitrogen and water supply on evapotranspiration, yield and agronomic water use efficiency of winter wheat
(2017-05-09)The predicted climate change for North West Europe, which will be characterized by higher temperatures and lower rainfall during the summer months, will challenge future food production. Against this background, the question ... -
A global barley diversity panel uncovered novel drought inducible QTL and footprints of evolution
(2017-03-13)The fibrous root system is a visible sign of ecological adaptation among barley natural populations. In the present study, we utilized rich barley diversity to dissect the genetic basis of root system variation and its ... -
The impact of large-scale land-acquisition in East Africa on poverty reduction and the rural economy: Studies in Ethiopia and Uganda
(2017-02-28)There is an increasing interest of acquiring farmland abroad, especially following the food price crisis in 2007/08. East Africa is a hotspot of activities, and given the high prevalence of poor people in the area, impacts ... -
Mechanistic details into NADPH oxidase mediated resistance against Heterodera schachtii in Arabidopsis thaliana
(2017-03-24)The oxidative burst, production of Reactive Oxygen Species (ROS) in response to pathogen attack, is an important component of plant defence mechanisms. It is now generally recognised that the major source of ROS during an ... -
Spatial variation of biomass energy supply and demand in rural Nepal
(2017-02-24)In Nepal, the share of biomass in total energy consumption is about 88 % and of biomass for cooking and heating about 90 % in 76 % of the households. Fuelwood, crop residues and dung are the three main biomass types. The ... -
Analysis of wheat (Triticum aestivum L.) resistance to cereal cyst nematode Heterodera filipjevi by genome-wide association mapping
(2017-02-14)The cereal cyst nematode <em>Heterodera filipjevi</em> is an important plant parasite causing substantial yield loss in wheat. The use of resistant cultivars is the preferable method to manage this nematode, however, only ... -
