Resilience, collapse and reorganization of a rangeland socio-ecological system in South Africa
(2016-05-24)Communal rangelands in semi-arid areas are complex socio-ecological systems (SES). Their complexity arises from non-linear feedbacks between the social- and the ecosystem. To understand the social system requires tackling ... -
Resistenzinduktion und Pathogenabwehr durch Reynoutria sachalinensis-Extrakt und Physcion: Signalkette im Vergleich zu systemischen Induktoren und Beziehungen zur Hypersensitiven Reaktion
(2004)Der heutige Stand der Forschung zeigt, daß die Vorgänge der Induzierten Resistenz (IR) bei Pflanzen relativ spezifisch in bezug auf verschiedene Induktoren, Wirtspflanzen und Pathogene sind. Neben vielen bekannten chemischen ... -
Resolving the inner circumstellar disks of T Tauri and Herbig Ae/Be stars with infrared interferometry
(2015-03-20)Circumstellar disks around young stellar objects (YSO) are a fundamental element of star and planet formation. The inner disk regions of pre-main sequence stars are hot enough for dust sublimation and a rim between dust-free ... -
Resonanzen und Repräsentationen der Alten Heimat: Musik und Musikkultur der Vertriebenen in der Bundesrepublik Deutschland
(2015-06-08)Im Kontext einer Erinnerungskultur, die sich als Folge der historischen Vorgänge von ‚Flucht und Vertreibung’ entwickelt, spielen musikkulturelle Handlungen als Mittel der Identitätsbildung in der Bundesrepublik Deutschland ... -
Resource Allocation for Health in Tanzania – Determinants and Development Implications
(2015-04-09)The optimal allocation of scarce resources for health improvement is a crucial factor to lower the burden of disease and to strengthen the productive capacities of people living in developing countries. This research project ... -
Resource utilization and sustainability of conservation-based rice-wheat cropping systems in Central Asia
(2011-08-26)Excessive and inefficient water use, intensive soil tillage and decreasing soil fertility have caused land degradation and desertification, which are threatening the sustainability of rice-wheat systems in the irrigated ... -
Resource-efficient feeding of fattening pigs based on body composition related performance groups: Studies on technical and environmental aspects
(2021-10-26)Livestock husbandry is increasingly confronted with the growing demands for more animal welfare and better environmental protection. As the largest component of agricultural animals in meat production, fattening pig husbandry ... -
Responders and Non-responders to the therapy of Hypercholesterolemia: Serum ratio of lathosterol to campesterol predicts the outcome of the therapy with Sitostanol ester margarine and Ezetimibe
(2006)Plant stanol margarines are recommended as a lipid-lowering dietary supplement in the treatment of hypercholesterolemia. Parameters predicting the individual cholesterol-lowering effect have not been elucidated so far. ... -
The response of human myeloid cells to the infection with Listeria monocytogenes
(2013-05-22)Macrophages and dendritic cells (DC) constitute the first line of defense against invading microorganisms. These myeloid cells have been identified as the major components of the outer ringwall of suppurative granulomas ... -
Response of the Medial Octavolateral Nucleus (MON) in the Goldfish, Carassius auratus, to constant-amplitude and amplitude-modulated water wave stimuli
(2008)Lateral line units in the MON of goldfish exhibited phasic or tonic responses to constant-amplitude stimuli. When stimulated with amplitude-modulated stimuli, most MON units exhibited phasic-tonic or tonic responses ...

Restenose nach perkutaner transluminaler Koronar Angioplastie und Insertion/Deletion Polymorphismus im Gen für das Angiotensin-I-Konversionsenzym
(2006)Derzeit wird die Bedeutung des Insertions/Deletions (I/D) Gen-Polymorphismus (GP) im Intron 16 des Gens für das Angiotensin-I-Konversionsenzym (ACE) für kardiovaskuläre Erkrankungen kontrovers diskutiert. Für das D-Allel ... -
Retrieval of biophysical parameters from multi-sensoral remote sensing data, assimilated into the crop growth model CERES-Wheat
(2008)This study investigated the possibilities and constraints for an integrated use of a crop growth model (CERES-Wheat) and earth observation techniques. The assimilation of information derived from earth observation sensors ... -
Retrieval of cloud and rainwater from ground-based passive microwave observations with the multi-frequency dual-polarized radiometer ADMIRARI
(2015-03-24)A ground-breaking new-concept multi-wavelength dual-polarized passive microwave radiometer ADMIRARI (ADvanced MIcrowave RAdiometer for Rain Identification) has been developed to perform observations of atmospheric precipitating ... -
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 ... -
