Strategies for risk oriented inspections between customers and suppliers in agri-food supply chains
(2014-05-02)One of the primary outcomes of this thesis has been to develop an assessment model of the operational and organisational structure with regard to the AMOR approach (Alliances for the Mutual Organisation of Risk oriented ... -
Retrieval of Sea Level and Surface Loading Variations from Geodetic Observations and Model Simulations: an Integrated Approach
(2014-04-07)The mass distribution in the system Earth changes dynamically over time. Time-variable mass transport mainly arises from the interplay between the terrestrial hydrological water cycle, the ocean and atmosphere, and the ... -
Characterisation of fitness parameters and population dynamics of Botrytis cinerea for the development of fungicide resistance management strategies in grapevine
(2014-03-18)Gray mold caused by the fungus<i>Botrytis cinerea</i> is an economically important disease in grapevine. The pathogen has a high tendency to become resistant to frequently applied systemic fungicides. Only a few years after ... -
Energy and protein intake, anthropometrics, disease burden and 1-year mortality in elderly home-care receivers living in Germany
(2014-02-25)The demographic structure in Germany has changed remarkably within the last decades. The number of old and very old people rises steadily and subsequently the number of elderly home-care receivers. Quality of life of this ... -
Assessing People´s Early Warning Response Capability to Inform Urban Planning Interventions to Reduce Vulnerability to Tsunamis: Case Study of Padang City, Indonesia
(2014-03-10)In the last decade, more emphasis is given on the human aspect of early warning or the attribute of “people-centered” early warning systems. This study seeks to better understand the specific conditions that shape people´s ... -
Analysis of functional candidate genes related to ubiquitination process for meat quality in commercial pigs
(2014-03-07)During the conversion from muscle to meat, the degradation of myofibrillar proteins impacts on the water holding capacity of meat. Besides the calpain/calpastatin proteolytic system, the activity of ubiquitin proteasome ... -
Characterization of adiponectin at different physiological states in cattle based on an in-house developed immunological assay for bovine adiponectin
(2014-02-07)Adipose tissue (AT), through secretion of adipokines, plays a central role in regulating metabolism. Adiponectin is one of the most abundant adipokines and is linked with several physiological mechanisms such as insulin ... -
Life cycle assessment of carbon and energy balances in Jatropha production systems of Burkina Faso
(2014-05-12)Modern bioenergy offers several advantages to Burkina Faso, a country that is heavily dependent on imported fossil fuel and greatly relying on traditional biomass use. In this context, Jatropha curcas has been recently ... -
Herbicide Resistance: Molecular and Physiological Characterization of the Glyphosate Resistant Weeds Amaranthus ssp. and Sorghum ssp.
(2014-02-06)Herbicides are an important tool for agricultural production to control weeds, avoid soil erosion, and maintain high yields. Highly competitive weeds like <i>Amaranthus</i> ssp. and <i>Sorghum halepense</i> have to be ... -
Entwicklung einer optimierten Produktion von Miscanthus-Mischpellets für Kleinfeuerungsanlagen
(2014-02-17)Die umweltverträgliche „low-input“-Kultur <em>Miscanthus x giganteus</em> ist einer der ertragsstärksten und am vielfältigsten einsetzbaren Nachwachsenden Rohstoffe. Ziel der Dissertation war es zu prüfen, welche Faktoren ... -
Infection and spread of Peronospora sparsa on Rosa sp. (Berk.): a microscopic and a thermographic approach
(2014-01-21)Downy mildew caused by Peronospora sparsa is one of the most destructive disease of roses, observed to produce asymptomatic infections and therefore difficult to control. The present research took different approaches to ... -
Comparative studies on the infection and colonization of maize leaves by Fusarium graminearum, F. proliferatum and F. verticillioides
(2014-09-01)Infection of <em>Fusarium</em> species causes quantitative along with qualitative damage on small grains and maize plants. This is due to leaf damage together with contamination by formation of different mycotoxins. Because ... -

(2014-01-17)The key objective of the present work was to acquire fundamental knowledge on the impact of nutrient supply and light quality on the accumulation of pharmaceutically relevant secondary metabolites, particularly saponins ... -
Vitamin K dependent γ-carboxylation in chronic kidney disease
(2014-01-10)Vascular calcification is present in atherosclerosis, ageing, chronic kidney diseases and diabetes and is strongly associated with an increased morbidity and mortality. Calcification of arteries occurs at the tunica intima ... -
Probiotics as a novel approach to modulate incretins, insulin secretion and risk factors of type 2 diabetes and complications
(2014-01-10)<u>Background and Aim</u>: Ingestion of probiotics can modify gut microbiota and alter insulin resistance and diabetes development in rodents. We hypothesized that daily intake of <em>Lactobacillus (L.)</em> reuteri increases ... -
On High Performance Computing in Geodesy: Applications in Global Gravity Field Determination
