The relevance of proximity and work-related experience for the individual support for the expansion of power plants: An empirical analysis of wind, coal, and nuclear energy
(2024-06-14)
This paper empirically examines whether proximity to power plants and work-related experience in the wind, coal, and nuclear energy sectors are correlated with the individual support for the expansion of corresponding regional power plants. The data for this analysis stem from a large-scale computer-based survey among more than 3700 citizens in Germany. The econometric analysis with binary and ordered probit models reveals significantly positive correlations between work-related experience in a specific energy sector ...

The efficacy of spatio-temporal predictors in forecasting the risk of Cydia nigricana infestation
(2024-03-15)
The ability to estimate the risk of pest infestation can help farmers to reduce pesticide application and provide guidance that would result in better management decisions. This study tested whether different combinations of spatial and temporal risk factors may be used to predict the damage potential of pea moth, Cydia nigricana Fabricius (Lepidoptera: Tortricidae), a major pest in field pea (Pisum sativum L., Fabaceae). Over four consecutive years, the abundance of pea moth was monitored by placing pheromone traps ...

Enabling magnetic pulse welding for dissimilar tubular arrester cable joints
(2024-04-08)
Climate change exacerbates the need for resource-efficient and cost-effective production processes across manifold industries, including the field of electrical connections. This specific field is characterized by a conflict of objectives, i.e., weight reductions while maintaining joint strength and electrical conductivity. From a material point of view, the use of aluminum as a conductor material is suitable for this application, as it is lighter than copper, a classical conductor material. Electrical conductors are ...

Distinguishing fast change in social norms and slow change in personal norms in cooperative decision-making
(2024-05-30)
Psychological research on norms has shown that norms are highly relevant for individuals’ decision-making. Yet, there is so far little understanding of how norms change over time. Knowledge about how norms change may help better understanding their potential for as well as limitations in guiding decision-making and changing behavior. The present work investigated change in individuals’ cooperation norms. As an indicator of different underlying processes of norm change, the temporal dynamics of different types of norms ...

Mathematical modelling of a latent heat storage: Influence of PCM thermal conductivity and enthalpy-temperature relationship
(2024-06-08)
Mathematical modelling of latent heat storage units is useful to calculate their thermal performance for integration in larger systems. This requires the input of thermophysical properties of the phase change material (PCM) used, but data provided by manufacturers or published in the literature is often incomplete and/or varies between sources. However, it is not clear to what extent an accurate knowledge of these properties, including their phase dependency, is necessary to obtain reliable calculations, especially ...

Using co-creation to build knowledge on cultural ecosystem services – A tiered approach for enhanced regional economic development of Réunion Island
(2024-06-01)
Cultural Ecosystem Services (CES) are highly context-specific and inherently linked to local identity, which challenges their assessment. Participatory methods have proven to capture the multiple values and aspects of CES for local communities. This paper presents an attempt to understand the different dimensions of CES in the Saint-Philippe municipality, Réunion Island, France. We applied a tiered, participatory approach that utilises knowledge co-creation processes over a period of 3 years. First, we co-created the ...

Acceptance of demand-side flexibility in the residential heating sector — Evidence from a stated choice experiment in Germany
(2024-05-22)
The growing share of renewables and the electrification of the transport and heating sectors are increasingly leading to an imbalance between electricity supply and demand in the distribution grids at the regional and local level. While the supply side is becoming increasingly flexible and volatile, the demand side is largely rigid and inflexible, especially at the household level. However, households have great potential to provide flexibility for grid stability by matching their electricity demand to supply. In ...

Mechanical Analysis and Simulation of Wood Textile Composites
(2024-05-18)
Wood Textile Composites (WTCs) represent a new and innovative class of materials in the field of natural fiber composites. Consisting of fabrics made from willow wood strips (Salix americana) and polypropylene (PP), this material appears to be particularly suitable for structural applications in lightweight construction. Since the threads of the fabric are significantly oversized compared to classic carbon or glass rovings, fundamental knowledge of the mechanical properties of the material is required. The aim of ...

Self-generation and outage losses: A firm-level analysis for emerging and developing Asian countries
(2024-02-26)
Access to reliable and affordable electricity is critical to economic development in emerging and developing Asia. However, many firms in these regions face challenges in obtaining consistent and affordable electricity from the grid, leading them to invest in self-generation technologies. This paper examines the strategic decision of firms to self-generate electricity and the economic losses incurred during power outages. Using survey data from the World Bank Enterprise Survey (WBES) of 5639 manufacturing firms in ...

Performance comparison of a fixed-bed solar grain dryer with and without latent heat storage
(2024-04-21)
Latent heat storage has gained attention as an energy storage method for solar drying due to its high storage density. However, its overall impact in drying performance has not been sufficiently investigated. This study presents detailed, validated mathematical models necessary for the transient simulation of a solar dryer with latent heat storage with the aim of assessing the effect that such storage has on the deep bed drying of wheat. Computer simulations were run with weather data from Germany. A fixed bed dryer ...
