Influence of ethylene oxide and gamma irradiation sterilization processes on the degradation behaviour of poly(lactic acid) (PLA) in the course of artificially accelerated aging
(2024-02-10)
To promote the application of bio-based materials in the field of medical technology, it is essential to conduct additional research, focusing on their long-term performance after sterilization. For this purpose, the study examines the aging behaviour of three poly(lactic-acid) (PLA) materials, sterilized with either ethylene oxide or gamma irradiation, over a two years aging period, in accordance with ASTM F1980-21. During these investigations, a direct correlation between moisture absorption and degradation progression ...

Putting Walkscapes on the Map: GIS-based Visualization for Mobile Methods in Landscape Research
(2024)
The idea of exploring landscapes by walking is historically and socially deeply rooted and fundamental to our modern understanding of landscapes but is often methodologically underrepresented. This paper illustrates that walking can be considered and applied as a method in landscape research. After a brief explanation of walking as a source of knowledge, a selection of mobile methods from literature is explained and their potential in landscape research is outlined. Based on these expla-nations, a new and innovative ...

Robotically winded full scale timber prototypes
(2024-05-10)
Additive manufacturing is a promising and resource-efficient construction method, applying material only where needed. Demand for these processes in construction is growing, but research into their use in timber construction is limited. The 3DWoodWind project explores additive application methods using thin wood veneer strips. Robotic winding processes can be used to develop wood-based hollow parts with minimal material input and optimised structural properties. This paper presents a modular building system of ...

The political: A view from Jakarta's kampungs
(2024-04-26)
This article is a response to Leitner and Sheppard’s recent publications on Jakarta. I argue that Jakarta’s kampungs and the eviction of their communities is a topic that needs to be situated in the realm of social reproduction. The multidimensional problems in kampungs fall within capitalism’s wider ‘crisis of care’. From this methodological position, we can access the political domain of the kampung, from which a new political agency emerges as collective bodies beyond merely the sum of individual survival tactics.

Analysis of the Similarity between Injection Molding Simulation and Experiment
(2024-05-01)
In the plastics industry, CFD simulation has been used for many years to support mold design. However, using simulation as a substitute for experimentation remains a major challenge to this day. This is due to the unknown congruence between simulation and experiment. The present work focuses on a comparison between simulation (generated with the software Moldflow Insight Ultimate from Autodesk Inc., San Francisco, CA, USA) and experiment by using molds of different complexity, where, in contrast to a large number of ...

Peak shaving at system level with a large district heating substation using deep learning forecasting models
(2024-05-20)
The decarbonisation of urban district heating (DH) systems requires increased heating grid flexibility. Therefore, this article examines the optimised operation of a tank thermal energy storage (TTES) on the secondary side of a new DH substation for an industrial site in a German city, in order to shave the peaks of the whole DH system and thus reduce the need for heat-only boilers (HOB). The accuracy of heat load and return temperature forecasts for both the industrial consumer and the DH grid is critical to the ...

Conditions and Effects of Norm Internalization
(2023-01-31)
Norm internalization refers to the process of adoption of normative beliefs by individuals, thus representing a link between individual and social change. However, there are several questions regarding norm internalization which need to be answered. These include understanding under which circumstances norm internalization does occur by considering the effects of internalizing either a certain norm or even conflicting norms. To investigate the conditions and effects of norm internalization, we developed a theoretical ...

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 ...

Dynamic tensile deformation behavior of AISI 316L stainless steel fabricated by laser-beam directed energy deposition
(2023-11-07)
The dynamic deformation behavior of metallic materials is the key to crash-safe design in many applications, e.g., in the automotive sector. However, in the field of additive manufacturing, dynamic deformation properties have only been scarcely studied. Based on the intrinsic interrelationships of process parameters, post-process heat treatments and the resulting microstructure, the present study seeks to provide a holistic overview of the dynamic tensile deformation properties of AISI 316L stainless steel, fabricated ...

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 ...
