Prediction of biomass and N fixation of legume-grass mixtures using sensor fusion
(2021-01-21)
European farmers and especially organic farmers rely on legume–grass mixtures in their crop rotation as an organic nitrogen (N) source, as legumes can fix atmospheric N, which is the most important element for plant growth. Furthermore, legume–grass serves as valuable fodder for livestock and biogas plants. Therefore, information about aboveground biomass and N fixation (NFix) is crucial for efficient farm management decisions on the field level. Remote sensing, as a non-destructive and fast technique, provides ...

Effect of Fibre Material and Fibre Roughness on the Pullout Behaviour of Metallic Micro Fibres Embedded in UHPC
(2020-07-14)
The use of micro fibres in Ultra-High-Performance Concrete (UHPC) as reinforcement increases tensile strength and especially improves the post-cracking behaviour. Without using fibres, the dense structure of the concrete matrix results in a brittle failure upon loading. To counteract this behaviour by fibre reinforcement, an optimal bond between fibre and cementitious matrix is essential. For the composite properties not only the initial surfaces of the materials are important, but also the bonding characteristics ...

Farmers’ and Herders’ Perceptions on Rangeland Management in Two Agroecological Zones of Benin
(2021-04-16)
The sustainable use of rangelands in pastoral areas requires the inclusion of all stakeholders to develop sound management strategies. However, the role of these actors in the sustainable management of natural resources is still poorly understood. The present study aims to (i) assess the perception of farmers and herders of the risks and opportunities of transhumance on rangeland resource use and management, and to (ii) generate useful knowledge for the design and implementation of policies that favor the coexistence ...

Automatically Detected Pecking Activity in Group-Housed Turkeys
(2020-11-04)
Simple Summary
Cannibalism is one of the biggest welfare issues of today’s turkey husbandry. We hypothesized that changes in pecking activity might indicate imminent cannibalism. Therefore, in this pilot study a newly developed automatic pecking activity detection was validated, and continuously applied to gain information about pecking activity of group-housed turkeys during the rearing phase and before a cannibalistic outbreak. The pecking object was used by turkeys the whole recording time. Activity on the object ...

Felder und Akteur*innen kultureller Bildung in ländlichen Räumen
(2021-04-01)
Das vom Bundesministerium für Bildung und Forschung (BMBF) geförderte Verbundvorhaben zielt auf eine empirisch fundierte Darstellung der kulturellen Landschaften und insbesondere der Akteur*innenkonstellationen der kulturellen Bildung in drei als peripher bis sehr peripher gekennzeichneten Regionen. Konkret wird mittels quantitativer und qualitativer Erhebungsmethoden den Fragestellungen nachgegangen, welche Felder und Akteur*innen in welcher Form und mit welchen Angeboten den Kultursektor bespielen, welche ...

Gestalt in Coaching und Beratung
(2020-07-29)
Der Erfolg der Gestalttherapie besteht nicht nur darin, dass sie sich seitdem als wichtige Therapierichtung etabliert hat, sondern in ihren theoretischen und praktischen Einflüssen z. B. auf die Systemtheorie, die Motivations‑, Persönlichkeits‑, Lern- und Entwicklungs‑, Organisations- und Arbeitspsychologie sowie die praktischen Anwendungen in Coaching, Organisationsberatung und Change-Management. Die „offene Gestalt“, Achtsamkeit und „Awareness“, Orientierung an eigenen Bedürfnissen und Wünschen, Selbstsorge, ...

Placemaking in Action: Factors That Support or Obstruct the Development of Urban Community Gardens
(2020-01-16)
The paper examines factors that support or obstruct the development of urban community garden projects. It combines a systematic scholarly literature review with empirical research from case studies located in New Zealand and Germany. The findings are discussed against the backdrop of placemaking processes: urban community gardens are valuable platforms to observe space-to-place transformations. Following a social-constructionist approach, literature-informed enablers and barriers for the development of urban community ...

Induction of protein aggregation and starvation response by tRNA modification defects
(2020-08-29)
Posttranscriptional modifications of anticodon loops contribute to the decoding efficiency of tRNAs by supporting codon recognition and loop stability. Consistently, strong synthetic growth defects are observed in yeast strains simultaneously lacking distinct anticodon loop modifications. These phenotypes are accompanied by translational inefficiency of certain mRNAs and disturbed protein homeostasis resulting in accumulation of protein aggregates. Different combinations of anticodon loop modification defects were ...

Carbon use efficiency and microbial functional diversity in a temperate Luvisol and a tropical Nitisol after millet litter and N addition
(2020-07-10)
Tropical soils often contain less soil organic C (SOC) and microbial biomass C (MBC) than temperate soils and, thus, exhibit lower soil fertility. The addition of plant residues and N fertilizers can improve soil fertility, which might be reflected by microbial C use efficiency (CUE) and functional diversity. A 42-day incubation study was carried out, adding leaf litter of the C4 plant finger millet (Eleusine coracana Gaertn.) and inorganic 15N fertilizer. The aim was to investigate amendment effects on CUE and ...
