(2019-01-09)<em>Miscanthus</em> bietet als nachwachsende Industrie- und Energiepflanze zahlreiche Vorteile, die neben den direkten landwirtschaftlichen Anwendungen wie Verbrennung und Tiereinstreu auch eine stoffliche Nutzung im ... -
Assessment of incidence, severity and distribution patterns of citrus greening in Kenya and Tanzania; the role of African Citrus Triozid endosymbionts in disease epidemiology
(2019-01-02)Infestation by insect pests and infection of disease causing pathogens are among the major biotic constraints hindering production, profitability and contribution of citrus to economic development. The African citrus triozid ... -
Extrinsic Calibration and Ego-Motion Estimation for Mobile Multi-Sensor Systems
(2018-12-20)Autonomous robots and vehicles are often equipped with multiple sensors to perform vital tasks such as localization or mapping. The joint system of various sensors with different sensing modalities can often provide better ... -
Deciphering the role of apoplastic root barriers in the interaction between sedentary nematodes and Arabidopsis
(2018-12-13)The plant-parasitic nematode species Heterodera schachtii and Meloidogyne incognita infect economically important crop plants in the entire world. Their infection causes yield losses, but effective and environmentally ... -
Metabolic profiling in serum and muscle of dairy cows during the periparturient period and the subsequent lactation
(2018-12-17)The transition period in dairy cows, spanning three weeks before and after parturition, is characterized by complex metabolic processes required for the homeorhetic adaptation to the needs of late pregnancy and the onset ... -
Identification and functional characterization of core effectors from cyst nematodes through comparative genomics
(2018-12-18)Plant parasitic nematodes (PPNs), are one of the most important constraints in agricultural production causing substantial losses in quantity and quality of food. The economically most important PPNs are the sedentary ... -
Intrinsically antimicrobial active polymers to improve the hygienic conditions during processing and preparation of fresh meat
(2018-12-10)The objective of this thesis was the investigation of the potential of intrinsically antimicrobial active polymers to improve the hygienic conditions in all steps of the processing and preparation of fresh meat, from the ... -
Exploring ethylenediurea (EDU) as an ozone biomonitoring and screening tool for rice (Oryza sativa L.)
(2018-12-10)Tropospheric ozone concentrations are rapidly rising in many developing parts of the world, thereby threatening food security. Therefore, breeding for adapting rice varieties is essential in Asia, especially in the Indian ... -
Analyzing photosynthetic performance in natural fluctuating environment using light-induced fluorescence transient (LIFT) method in high-throughput
(2018-12-04)In the present work, the knowledge gap concerning the interaction of photosynthesis with its fluctuating environment was filled by acquiring over one million chlorophyll fluorescence measurements in semi-field and field ... -
Post-harvest losses in Sub-Saharan Africa: measurement concepts and economic assessment of reduction strategies
(2018-11-27)Post-harvest loss (PHL) is a major source of inefficiency in the agricultural value chain in Sub-Saharan Africa (SSA). It wastes productive resources, reduces economic agents' income, and aggravates the problem of insufficient ... -
Einfluss von Bodenhilfsstoffen auf die Wasserhaltekapazität bewässerter Böden
(2018-12-05)Das Ziel der vorliegenden Dissertation war es, den Einfluss von Bodenhilfsstoffen auf die Wasserhaltekapazität (WHK) von Böden mit unterschiedlichen Bewässerungssystemen zu untersuchen. Um die Wirkung dieser Stoffe in der ... -
Sensor fusion for localization of automated vehicles
(2018-12-13)Automated vehicles need to precisely know where they are at all times to be able to make informed driving decisions. Therefore, multiple localization systems are typically installed on such vehicles to provide redundant ... -
Robot Mapping and Navigation in Real-World Environments
(2018-11-27)Robots can perform various tasks, such as mapping hazardous sites, taking part in search-and-rescue scenarios, or delivering goods and people. Robots operating in the real world face many challenges on the way to the ... -
Prospects of Cooperation in the Eastern Nile Basin: The case of Experimental Game Application
(2018-11-23)Tensions over the use of Nile waters have recently increased and no comprehensive agreement till date acceptable to all Eastern Nile Basin riparian countries exists. After years of escalating tensions between upstream and ... -
High precision lysimeters improve our understanding of water cycle and solute transport dynamics
(2018-11-28)Water is the most precious natural resource on earth. Understanding the movement of water and dissolved substances between the different compartments soil, vegetation, and atmosphere is of crucial importance to resolve ... -
Investigating the Potential of UAV-Based Low-Cost Camera Imagery for Measuring Biophysical Variables in Maize
(2018-11-27)The potential for improved crop productivity is readily investigated in agronomic field experiments. Frequent measurements of biophysical crop variables are necessary to allow for confident statements on crop performance. ... -
Identification and characterisation of Heterodera schachtii susceptibility genes AtPANB1 and HIPP27 in Arabidopsis thaliana
(2018-11-08)Sedentary plant-parasitic cyst nematodes are obligate biotrophs that infect the roots of their host plant. Their parasitism is based on modification of infected root cells to form a hypermetabolic syncytium from which the ...
