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 ...

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 ...

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 ...

Mapping Invasive Lupinus polyphyllus Lindl. in Semi-natural Grasslands Using Object-Based Image Analysis of UAV-borne Images
(2020-08-07)
Knowledge on the spatio-temporal distribution of invasive plant species is vital to maintain biodiversity in grasslands which are threatened by the invasion of such plants and to evaluate the effect of control activities conducted. Manual digitising of aerial images with field verification is the standard method to create maps of the invasive Lupinus polyphyllus Lindl. (Lupine) in semi-natural grasslands of the UNESCO biosphere reserve “Rhön”. As the standard method is labour-intensive, a workflow was developed to ...

Revisiting climate change effects on winter chill in mountain oases of northern Oman
(2020-10-07)
For centuries, traditional high-altitude oases in Oman have depended on the cultivation of deciduous fruit trees. This study explores the effects of climate change on winter chill (estimated as Chilling Hours—CH and Chill Portions—CP), a prerequisite to overcoming dormancy and initiating flowering, in three Omani oases. The results are compared with findings from an earlier study which reported a decrease in the numbers of CH in high-elevation oases by an average of 1.2–9.5 CH year−1 between 1983 and 2008. Location-specific ...

A value-theoretic approach to economic dynamics and evolution—synthesizing different Marxian modules in a simulation model
(2020-05-08)
This part is devoted to simulation experiments based on the simulation model developed in part I from the value-theoretic reconstruction of the main parts of Marx’s critique of Political Economy. After introducing the main parameters and the range of their variation (Section 1), a singular run as well as a sensitivity analysis for the chosen standard configuration (‘moderation regime’) is presented in Section 2. This is accomplished by configurations depicting characteristics of the capitalist development emphasized ...
