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 ...

Zum Forschungsstand über Ansätze des Dual Career Coachings
(2021-04-13)
Der vorliegende Artikel zeigt den Forschungsstand zur Beratung von Dual Career Couples (DCCs) anhand von zehn theoretisch, empirisch und praxeologisch entwickelten Ansätzen auf. Zunächst wird die Bedeutung des Phänomens DCCs für die Karriereberatung konturiert und anschließend vor dem Hintergrund gesellschaftlicher Transformationsprozesse eingeordnet. Die Einführung eines triadisch konzeptualisierten Beratungsraums schafft einen Rahmen, der eine vergleichende Darstellung und Einordnung der zehn Ansätze ermöglicht. ...

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 ...

Social Machines
(2021-11-11)
Social Machines sind ein Paradigma für die Gestaltung soziotechnischer Systeme, die unter Verwendung von Web- und Plattformlösungen das Potenzial digitaler Technologien mit der Eigenlogik sozialer Interaktion, Organisation und Strukturbildung auf neue Weise zusammenführen. Im Folgenden diskutieren wir das Paradigma der Social Machine aus den Perspektiven der Informatik, der Wirtschaftsinformatik, der Soziologie und des Rechts, um Orientierungspunkte für seine Gestaltung zu identifizieren. Der Begriff ist in der ...

Using New Spare Parts for Repair of Waste Electrical and Electronic Equipment? The Material Footprint of Individual Components
(2022-02-21)
The growing production of waste electrical and electronic equipment (WEEE) requires close loop management to protect the environment and save resources. Repair and reuse can extend the product’s life span. However, debates on the differences seen in resource consumption linked to the different ways of repairing devices have received a limited amount of attention. This article demonstrates quantification of the resource consumption (cradle-to-gate) of five types of appliances on a component level based on life-cycle ...

Wine quality under integrated, organic and biodynamic management using image-forming methods and sensory analysis
(2021-12-24)
Background and aims
The image-forming methods copper chloride crystallization, capillary dynamolysis and circular chromatography are presented as an instrument for assessing wine quality. Wine quality of samples from a long-term field trial comparing integrated, organic and biodynamic management were investigated by using image-forming methods and sensory analysis.
Methods and results
Concerning the image-forming methods copper chloride crystallization, capillary dynamolysis and circular chromatography, the images ...

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 ...
