Global Value Chains and the Role of Innovation for Sustainable Palm Oil: An International Bioeconomy Analysis for Malaysia
(2016-01-22)Palm oil constitutes approximately one-third of the 130 million tonnes of major vegetable oils and fats consumed annually worldwide. The use of bio-based materials in palm oil production and the potential to achieve a ... -
Identification of Relevant Patterns in Spectral Signatures
(2016-01-04)For Plant Phenotyping, non-invasive measurements of early stress processes in plants and the quantification of soil parameters with hyperspectral sensors are of particular importance, but relevant information is often ... -
Nutritional strategies and their influence on the expression of nutrient sensing G protein-coupled receptors in adipose tissue of dairy cows
(2015-12-03)Adipose tissue (AT) plays a central role in the regulation of metabolism at the onset of lactation as a major contributor of energy through the mobilization of nonesterified fatty acids. This time period is especially ... -
Soil and water conservation technologies in the West African Sudan Savanna: Cropping system options to address variability of crop yield and impacts of climate change
(2015-12-03)In the Sudan Savanna region of West Africa, smallholder agricultural production is almost entirely rain-fed. Some of the major constraints to crop production are low soil fertility and high intra- and inter-annual rainfall ... -
Dietary strategies to optimize energy and glucose supply to lactating dairy cows
(2015-11-24)Ruminants usually absorb only small quantities of glucose directly from the small intestine, because the majority of the glucose, regardless of dietary source, is fermented in the rumen to short chain fatty acids. Thus, ... -
Optimierung der Temperaturüberwachung von nicht aktiv gekühlten Pharma Supply Chains
(2015-12-03)Das Ziel der vorliegenden Arbeit war die Entwicklung einer Methode zur Optimierung der Temperaturüberwachung in nicht aktiv gekühlten Pharma Supply Chains. Dabei galt es zunächst ein Anforderungsprofil zu erstellen, welches ... -
Application and perspectives of non-invasive urinary biomarker measurements in epidemiological research on child nutrition: hydration and iodine status, two health-relevant examples
(2015-11-23)Non-invasive biomarkers of nutritional status provide a promising and alternative measure of dietary intakes in epidemiological research. Hydration and Iodine Status are two examples of important predictors of long-term ... -
Effekte einer Nährstoffsupplementation (Molkenprotein und Kaliumbicarbonat) in Kombination mit Kraft- und Ganzkörpervibrationstraining auf den Knochenabbau in Bettruhe
(2015-12-03)Immobilisationsbedingte Veränderungen des muskuloskeletalen Systems führen auf Grund von fehlender Belastung zu Inaktivitätsatrophie und –osteoporose. Bereits nach kurzer Zeit wird dies durch einen verstärkten Knochenabbau ... -
Welfare and Economy-Wide Effects of Azerbaijan’s Accession to the World Trade Organization: A Quantitative Assessment
(2015-11-10)Azerbaijan applied for membership in the World Trade Organization (WTO) in 1997 and negotiations are still ongoing. Accession to the WTO requires the applicant countries to align economic policies with the organization’s ... -
Interpretation of L-band brightness temperatures of differently tilled bare soil plots
(2015-12-03)The structure of the surface soil layer is strongly influenced by soil tillage practices with important consequences for the soil hydraulic properties and soil moisture dynamics in the top soil layer. In this study, an ... -
Plant parameters for the marker and trait assisted selection of drought stress tolerance in barley (Hordeum vulgare ssp. vulgare)
(2015-12-03)The scarcity of water resources is becoming one of the most devastating stress factors for plants, which elicits a variety of responses. Therefore, effective screening techniques are necessary to understand the mechanism ... -
Micronutrient status in morbidly obese patients undergoing bariatric surgery - assessment and intervention
(2015-10-30)Although the benefits of bariatric surgery have been frequently proven, less is known about the micronutrient status of morbidly obese patients undergoing bariatric surgery. A deficiency in vitamin D pre- and postoperatively ... -
Farmer Innovation in Rural Ghana: Determinants, Impacts and Identification
(2015-11-23)Innovation is essential for agricultural and economic development, especially in today’s rapidly changing global environment. While farmers have been recognised as one of the key sources of innovation, many studies on ... -
Ecological interactions of Fusarium species and the meal beetle Tenebrio molitor
(2015-10-14)Contamination of stored grains by moulds and their mycotoxins results in quality and nutritional reduction. Ingestion of contaminated products and feed poses a significant hazard to human and animal health. The moulds ... -
Untersuchungen zur Eignung des „Auerochsen" für Ganzjahresbeweidung: Aspekte der Physiologie und Habitatnutzung
(2015-10-14)Der Einsatz großer Pflanzenfresser in extensiver Ganzjahresbeweidung ist ein viel diskutiertes Konzept. Die mit Herbivorie einhergehenden, natürlich ablaufenden Prozesse sollen unterstützt werden, um eine maximale Biodiversität ... -
Untersuchung der Kälteanpassungsmechanismen bakterieller Zellmembranen
(2015-10-14)Die Lebensmittelindustrie versucht stetig, die Haltbarkeit ihrer Produkte zu verlängern, um ihre Produktivität zu optimieren. Dafür verwendet sie auch Kühlungs- und Gefriertechniken. Durch den Einsatz dieser Techniken ... -
Convex Optimization for Inequality Constrained Adjustment Problems
(2015-10-14)Whenever a certain function shall be minimized (e.g., a sum of squared residuals) or maximized (e.g., profit) optimization methods are applied. If in addition prior knowledge about some of the parameters can be expressed ... -
Cellular energy supply and aging in dairy cows: Characterization of different physiological states and impact of diet-induced over-condition
(2015-09-24)Lactation in dairy cows is accompanied by dramatic changes in energy balance and thus requires the continued adaption of the key organs, namely adipose tissue (AT), liver, and mammary gland to the varying conditions. The ... -
International Cooperation for the Conservation and Sustainable and Fair Use of Biodiversity
(2015-09-17)This thesis contributes to the modelling of intergovernmental cooperation for global biodiversity conservation and analyses multilateral cooperation on the genetic resource market. The inter- and transdisciplinary research ... -
Genome-wide association study for reproduction traits in maternal pig breeds
(2015-11-23)The number of piglets born alive (NBA) is one of the most important reproduction traits due to its influence on pig production efficiency. It was shown in several studies that NBA has an antagonistic relationship with later ...
