Spatial and Temporal Variations of Stable Isotopes in Precipitation in the Mountainous Region, North Hesse
(2022-12-01)
Patterns of stable isotopes of water (¹⁸O and ²H) in precipitation have been used as tracers for analyzing environmental processes which can be changed by factors such as the topography or meteorological variables. In this study, we investigated the isotopic data in precipitation for one year in the low mountain range of North Hesse, Germany, and analyzed mainly for altitude, rainfall amount, and air temperature effects on a regional scale. The results indicate that the isotopic composition expressed an altitude ...

The potential of metabarcoding plant components of Malaise trap samples to enhance knowledge of plant-insect interactions
(2022-07-22)
The worldwide rapid declines in insect and plant abundance and diversity that have occurred in the past decades have gained public attention and demand for political actions to counteract these declines are growing. Rapid large-scale biomonitoring can aid in observing these changes and provide information for decisions for land management and species protection. Malaise traps have long been used for insect sampling and when insects are captured in these traps, they carry traces of plants they have visited on the body ...

Extended Reality in Marketing - A Multiple Case Study on Internet of Things Platforms
(2022-05-27)
This research highlights how cloud platform as a service technologies host extended reality technologies and convergent technologies in integrated solutions. It was only around 2019 that scholarly literature conceptualized the role of extended reality, that is, augmented reality, virtual reality, and mixed reality, in the marketing function. This article is a multiple case study on the leading eleven platform as a service vendors. They provide the programming technology required to host software as a service in the ...

Grain growth and precipitation behaviour of AISI 430 ferritic stainless steel subjected to pulsed laser beam welding using free-form pulse shaping
(2022-10-26)
Ferritic stainless steels are prone to grain coarsening and precipitation of chromium-rich grain boundary phases during fusion welding, which increase intergranular corrosion susceptibility. State-of-the-art techniques to overcome these challenges mainly feature heterogeneous nucleating agents with regard to grain coarsening or alternating alloy concepts as well as post-weld heat treatments as for restoration of intergranular corrosion resistance. The present investigation seeks to depart from these traditional ...

Dissimilar micro beam welding of titanium to Nitinol and stainless steel using biocompatible filler materials for medical applications
(2022-11-16)
In the present investigation, thin sheet geometries of commercially pure titanium (cp, grade 4) are butt-welded to AISI 316L stainless steel as well as Nitinol by means of micro electron beam welding using filler materials. In order to avoid mixing of the base materials, the refractory metals tantalum, niobium and hafnium are applied as intermediate layers. Owing to the biocompatibility of these filler materials, the final products are suitable for medical technology applications. In combination with low energy inputs ...

Late to the Party—Transferred Mulch from Green Manures Delays Colorado Potato Beetle Infestation in Regenerative Potato Cropping Systems
(2022-12-12)
The Colorado potato beetle (CPB) is an exceptionally challenging potato pest. Some regenerative farmers have reported that the use of transferred green manure mulch can considerably reduce CBP damage. Previous studies confirm this observation, but mainly with straw mulch, which is rarely used in Central Europe, and not embedded in the new regenerative cropping approach. For this, six trials conducted between 2014 and 2019 were evaluated, comparing CPB infestation in potatoes with and without transferred mulch as well ...

Kultur, Soziale Arbeit und Kulturelle Bildung
(2022-12-06)
Der Beitrag erörtert nach historischen Vergewisserungen die Wechselbeziehungen und die Zusammenarbeit zwischen kulturellen und sozialen Gesellschaftsbereichen, der Kulturellen Bildung und der Sozialen Arbeit. Angesichts gesellschaftlicher Veränderungen wird davon ausgegangen, dass eine konturenscharfe Trennung zwischen dem Kulturellen und dem Sozialen nicht mehr durchgängig möglich ist.

Farming system effects on root rot pathogen complex and yield of faba bean (vicia faba) in Germany
(2022-12-21)
A survey across Germany was undertaken from 2016-2019 to evaluate effects of management system (organic vs conventional), pedo-climatic conditions and crop rotation history on faba bean root health status, diversity of major root rot pathogens and yield. Root rot incidence was generally low and there was no effect of the management system on the spectrum of pathogens isolated. Among the most common fungal species identified, frequencies of Fusarium redolens and Didymella pinodella were significantly higher in roots ...

Housing in Germany and the Rebirth of the High‐Rise in Post‐Modern Urban Design
(2022-11-22)
High-rise buildings were a frequent design element in modernist urban planning and architecture. However, both the criticisms modernism faced and the negative experiences with large housing estates dating from that period led to post-modern designs that built strongly on traditional pre-modernist urban form. Despite the role of high-rise buildings in office areas, many brownfield and greenfield housing developments from the 1980s to the 2000s reflected this trend and abandoned high-rise buildings almost completely ...

Spatially explicit life cycle assessments reveal hotspots of environmental impacts from renewable electricity generation
(2022-08-30)
Renewable energy generation has great potential to reduce greenhouse gas emissions, however, it may exacerbate other environmental impacts, such as water scarcity, elsewhere in the supply chain. Here, we reveal a wide range of global environmental impacts of concentrated solar power, run-of-river hydropower, and biomass burning compared to classical coal-fired power: Spatially explicit life cycle impact assessment is used to evaluate their supply chains with respect to demand for energy, land, material, and water, ...
