Pastoral Practices, Economics, and Institutions of Sustainable Rangeland Management in Kenya
(2016-04-08)Rangelands contribute greater value than is generally acknowledged. The ecosystems provide a significant portion of the world’s biodiversity and culturally diverse habitats and are also of great ecological and economic ... -
Untersuchungen zur Steuerung und Kontrolle der Vermikompostierung von organischen Abfällen
(2016-03-29)Die Abwasserbehandlung muss die Aufgaben der Abwasseraufbereitung und der hygienisierenden Behandlung der Feststoffe erfüllen. Besonders in Wassermangelgebieten und dünn besiedelten Regionen bietet sich darüber hinaus die ... -
Generation, enrichment and characterization of bioactive oligosaccharides and peptides from milk
(2016-03-22)Milk is considered to be a rich and one of the most important sources of bioactive compounds containing various milk-borne biologically active constituents or precursor substances for bioactive components. The present work ... -
Interpretation of Aerial Images with Learned Graphical Models
(2016-02-16)In this thesis we present a new approach for image interpretation of aerial images using learned graphical models.<br /> The approach uses a region based hierarchical feature adjacency graph. This contains homogeneous ... -
Genetic and Physiological Analyses of the Tolerance Mechanisms to Ferrous Iron Toxicity in Rice (Oryza sativa L.)
(2016-04-20)Rice is a widely consumed staple food for more than half of the world population. Iron (Fe) toxicity is a major nutrient disorder affecting rice production. The understanding of the genetic and physiological basis of Fe ... -
Fahrspur- und Routenplanung für teilautonome, GNSS-gestützte Landmaschinen
(2016-02-19)Die Entwicklungen in der Landwirtschaft sind durch Automatisierung und Informationstechnologie geprägt. Parallelfahrsysteme sind zu einem wichtigen Werkzeug geworden, um die Maschine mit einer Spurgenauigkeit von wenigen ... -
Endocrine activity of adipose tissues as influenced by energy intake in the periparturient cow
(2016-02-09)With the onset of lactation, dairy cows have to mobilize body reserves, mainly in form of fat, to cover the energy output via milk. Homeorhetic adaptations, achieved via the orchestrated actions of hormones, are necessary ... -
Identification of candidate genes for porcine meat quality and investigation of effects of sulforaphane on porcine satellite cells
(2016-01-21)Meat quality has received more and more customer's attention. Muscle growth rate is closely related with the efficiency of pig production. Meat quality and muscle growth are two important issues in pig production. The ... -
Use of Biogenic Volatile Organic Compounds to assess the Health Status of Tomato Plants (Solanum Lycopersicum) cv. “Moneymaker”
(2016-02-16)The goal of the present study is to test if tomato biogenic volatile organic compounds (BVOC) can be used as an early stress indicator. In this study, influences of drought and biotic stresses on BVOC emissions were ... -
Sensing the response of sugar beet and spring barley to abiotic and biotic stresses with proximal fluorescence techniques
(2016-01-22)The aim of these studies was to evaluate the potential of non-destructive fluorescence techniques for the detection and differentiation of abiotic and biotic stress situations. For this purpose, sugar beet cultivars were ... -
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
