Factors and Components Affecting Dairy Smallholder Farmers and the Local Value Chain— Kvemo Kartli as an Example
(2021-05-20)
Smallholder farmers are the cornerstone of the livestock sector and an essential element in building and developing the local dairy value chain, critical for developing its local economy. In Georgia, and despite the efforts made since independence from the Soviet Union until now, farmers still face many problems that prevent them from participating effectively in developing the dairy value chain, especially heavy metal pollution that afflicts the study region. This research study refers to smallholder farmers’ ...

Role of SSD1 in Phenotypic Variation of Saccharomyces cerevisiae Strains Lacking DEG1-Dependent Pseudouridylation
(2021-08-15)
Yeast phenotypes associated with the lack of wobble uridine (U34) modifications in tRNA were shown to be modulated by an allelic variation of SSD1, a gene encoding an mRNA-binding protein. We demonstrate that phenotypes caused by the loss of Deg1-dependent tRNA pseudouridylation are similarly affected by SSD1 allelic status. Temperature sensitivity and protein aggregation are elevated in deg1 mutants and further increased in the presence of the ssd1-d allele, which encodes a truncated form of Ssd1. In addition, ...

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 ...

Sensitivity of Convection-Permitting Regional Climate Simulations to Changes in Land Cover Input Data: Role of Land Surface Characteristics for Temperature and Climate Extremes
(2021-10-14)
Characterization of climate uncertainties due to different land cover maps in regional climate models is essential for adaptation strategies. The spatiotemporal heterogeneity in surface characteristics is considered to play a key role in terrestrial surface processes. Here, we quantified the sensitivity of model results to changes in land cover input data (GlobCover 2009, GLC 2000, CCI, and ECOCLIMAP) in the regional climate model (RCM) COSMO-CLM (v5.0_clm16). We investigated land cover changes due to the retrieval ...

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 ...

Optical Quality of InAs/InP Quantum Dots on Distributed Bragg Reflector Emitting at 3rd Telecom Window Grown by Molecular Beam Epitaxy
(2021-10-21)
We present an experimental study on the optical quality of InAs/InP quantum dots (QDs). Investigated structures have application relevance due to emission in the 3rd telecommunication window. The nanostructures are grown by ripening-assisted molecular beam epitaxy. This leads to their unique properties, i.e., low spatial density and in-plane shape symmetry. These are advantageous for non-classical light generation for quantum technologies applications. As a measure of the internal quantum efficiency, the discrepancy ...

How political philosophies can help to discuss and differentiate theories in community ecology
(2021-04-09)
This paper uses structural analogies to competing political philosophies of human society as a heuristic tool to differentiate between ecological theories and to bring out new aspects of apparently well-known classics of ecological scholarship. These two different areas of knowledge have in common that their objects are ‘societies’, i.e. units composed of individuals, and that contradictory and competing theories about these supra-individual units exist. The benefit of discussing ecological theories in terms of their ...

Development of optical MEMS-based micromirror arrays on flexible substrate for curvilinear surfaces
(2021-04-18)
This research work is targeting to demonstrate that micromirror arrays can also be fabricated successfully on flexible substrates—not only on glass substrates. The paper reports on the technological data of a successful process on a flexible substrate for curvilinear surfaces. Polyethylene naphthalate substrate was selected for its low cost, strong resistance against chemicals which are used in fabrication process and sufficient optical transmission for the visible and near infrared spectrum. Finally, electrostatic ...

Urm1, not quite a ubiquitin-like modifier?
(2021-09-09)
Ubiquitin related modifier 1 (Urm1) is a unique eukaryotic member of the ubiquitin-fold (UbF) protein family and conserved from yeast to humans. Urm1 is dual-functional, acting both as a sulfur carrier for thiolation of tRNA anticodons and as a protein modifier in a lysine-directed Ub-like conjugation also known as urmylation. Although Urm1 conjugation coincides with oxidative stress and targets proteins like 2-Cys peroxiredoxins from yeast (Ahp1) and fly (Prx5), it was unclear how urmylation proceeds molecularly and ...

Qualifizierung der Qualifizierenden
(2021-08-24)
Die wachsende Aufmerksamkeit für die Lebensphase Kindheit fordert die beruflichen Qualifizierungsformate wie die entsprechenden akademischen Studienprogramme. Die Bewältigung des diagnostizierten Fachkräftebedarfs und die damit eng verbundene Herausforderung der weiteren Professionalisierung sind unterdessen nach wie vor ungelöst. Vor diesem Hintergrund werden in dem Beitrag Wandlungsprozesse sozialpädagogischer Qualifizierungsformate skizziert und an bildungsorientierte Erwartungen erinnert, die eine Ausdifferenzierung ...
