Determination of Local Electrical Properties Using a Potential Field Measurement for Electrically Conductive Carbon Fiber Reinforced Plastics with Metal Contact Pins Joined via Injection Molding
(2022-07-09)
Carbon fiber reinforced plastics (CFRP) bear a high potential in terms of electrical conductivity and its potential applications. A locally resolved electrical measurement method for these anisotropic materials is a key prerequisite for understanding the structural and manufacturing process-related interrelationships. The aim of this paper is to develop a measurement method that allows this to be achieved and also to investigate areas of overmolded metal contact pins in detail. CFRP samples with polyamide 6 and ...

Botanical concrete
(2022-06-30)
La ricerca sul Botanical Concrete indaga con un approccio innovativo, basato sul design thinking, i materiali e la fitotecnologia, nei sistemi di inverdimento per pareti al fine di dare nuove funzioni al calcestruzzo e consentire l’insediamento superficiale permanente contemporaneamente di crittogame e tracheofite, due specie con diverse esigenze di substrato che si traducono in due distinti requisiti del calcestruzzo. Dalla combinazione dei risultati delle sperimentazioni sulle crittogame e sulle tracheofite si ...

Enhancement of Weldability at Laser Beam Welding of 22MnB5 by an Entrained Ultrasonic Wave Superposition
(2022-07-09)
In this paper, the potential of directional ultrasonic wave superposition by moving sound generators for laser beam welding of high-strength steel alloys 1.5528 (22MnB5) is studied. Steel sheets of identical thickness and in form of tailored blanks were joined in butt joint configuration. The influences of the various excitation parameters of the moving sound generators on the ultrasonic coupling and their influence on the distribution of the AlSi coating components within the melting zone and the weld seam characteristics ...

Cultural Sensitivity in Preventive Infant Mental Health Care: An Example From the Developmental Guidance Project FIRST STEPS in Belgium
(2022-05-04)
Preventive developmental guidance programmes have been applied on a large scale for several decades now in many western countries. But how do we adapt these programs to families with very different ethnic backgrounds? How can we concretise the concept of cultural sensitivity into that context? The plea of von Klitzing, the former President of the World Association for Infant Mental Health, for further reflection on the concretization of cultural sensitivity in the context of infant mental health care is the main ...

Societal Evaluation of Bioeconomy Scenarios for Germany
(2022-05-05)
Transitioning to a bio-based economy is widely perceived as a necessary way to tackle climate change and other key environmental challenges. Given the major socio-economic consequences that such a transition entails for people’s everyday lives, it is crucial to take account of citizens’ perceptions and levels of acceptance of these changes. This study applies a holistic approach to gain an understanding of how citizens in Germany assess possible developments associated with transitioning to a bioeconomy. We developed ...

Teachers’ emotional exhaustion before and during the COVID-19 pandemic: Neither emotional exertion nor vacation feeling
(2022-08-08)
In this paper, we use latent change models to examine the changes in in-service teachers’ emotional exhaustion before and during the COVID-19 pandemic. As a result of the pandemic, teachers are confronted with challenging tasks, which can lead to stress and burnout. Resultingly, teachers’ stress experiences have been examined in different studies. However, often the change in those experiences remains unclear. Against this background, we investigate longitudinally how the emotional exhaustion of a cohort of German ...

Assessment of Multi-Satellite Precipitation Products over the Himalayan Mountains of Pakistan, South Asia
(2022-07-11)
Performance assessment of satellite-based precipitation products (SPPs) is critical for their application and development. This study assessed the accuracies of four satellite-based precipitation products (PERSIANN-CDR, PERSIANN-CCS, PERSIANN-DIR, and PERSIANN) using data of in situ weather stations installed over the Himalayan Mountains of Pakistan. All SPPs were evaluated on annual, seasonal, monthly, and daily bases from 2010 to 2017, over the whole spatial domain and at point-to-pixel scale. The assessment was ...

Loneliness and Emancipation: A Multilevel Analysis of the Connection between Gender Inequality, Loneliness, and Social Isolation in the ISSP 2017
(2022-06-17)
The present article analyzes the connection between, on the one hand, gender equality and, on the other hand, loneliness and social isolation. It hypothesizes that modern relational institutions that support gender equality, such as no-fault divorce laws, reduce loneliness in close relationships. This hypothesis is put to the test through a multilevel analysis of the International Social Survey Program (ISSP) 2017. The analysis reveals that the data agree, to a large extent, with the theoretical arguments. The ...

“Some hate it, others love it”: Formation of automatic and reflective affective processes toward exercising in fitness centers and mountain biking
(2022-03-18)
Based on a dual process approach, this study was conducted to test whether automatic affective processes toward exercise are not only interrelated with the amount of exercise but also distinctive for different types of exercise. In a quasi-experimental setting, N = 60 participants (30.87 years ± 7.53; 33% female) completed an Evaluative Priming task to assess automatic affective processes toward exercising in fitness centers, mountain biking and exercise in general and completed a questionnaire about their exercise ...

Comparative thermal analyses of solar milk pasteurizers integrated with solar concentrator and evacuated tube collector
(2022)
Solar-based milk pasteurization enables decentralized maintenance of milk in remote areas of developing countries like Pakistan. Two innovative and efficient medium temperature range solar techniques; solar concentrator (SC) and evacuated tube collectors (ETC) were employed and compared based on theoretical and experimental analyses for an expedient and effective milk pasteurization. The detailed thermal analyses of both techniques were conducted to investigate the useful energy and losses during pasteurization. The ...
