@article{47122, abstract = {{AbstractFeCo alloys are important materials used in pumps and motors in the offshore oil and gas drilling industry. These alloys are subjected to marine environments with a high NaCl concentration, therefore, corrosion and catastrophic failure are anticipated. So, the surface dissolution of additively manufactured FeCo samples is investigated in a quasi-in situ manner, in particular, the pitting corrosion in 5.0 wt pct NaCl solution. The local dissolution of the same sample region is monitored after 24, 72, and 168 hours. Here, the formation of rectangular and circular pits of ultra-fine dimensions (less than 0.5 µm) is observed with increasing immersion time. In addition, the formation of a corrosion-inhibiting surface layer is detected on the sample surface. Surface dissolution leads to a change in the surface structure, however, no change in grain shape or grain size is noticed. The surface topography after local dissolution is correlated to the grain orientation. Quasi-in situ analysis shows the preferential dissolution of high-angle grain boundaries (HAGBs) leading to a change in the fraction of HAGBs and low-angle grain boundaries fraction (LAGBs). For the FeCo sample, a potentiodynamic polarisation test reveals a corrosion potential (Ecorr) of − 0.475 V referred to the standard hydrogen electrode (SHE) and a corrosion exchange current density (icorr) of 0.0848 A/m2. Furthermore, quasi-in situ experiments showed that grains oriented along certain crystallographic directions are corroding more compared to other grains leading to a significant decrease in the local surface height. Grains with a plane normal close to the $$\langle {1}00\rangle$$ ⟨ 100 ⟩ direction reveal lower surface dissolution and higher corrosion resistance, whereas planes normal close to the $$\langle {11}0\rangle$$ ⟨ 110 ⟩ direction and the $$\langle {111}\rangle$$ ⟨ 111 ⟩ direction exhibit a higher surface dissolution.}}, author = {{Pramanik, Sudipta and Krüger, Jan Tobias and Schaper, Mirko and Hoyer, Kay-Peter}}, issn = {{1073-5623}}, journal = {{Metallurgical and Materials Transactions A}}, keywords = {{Metals and Alloys, Mechanics of Materials, Condensed Matter Physics}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{Quasi-In Situ Localized Corrosion of an Additively Manufactured FeCo Alloy in 5 Wt Pct NaCl Solution}}}, doi = {{10.1007/s11661-023-07186-7}}, year = {{2023}}, } @article{47117, abstract = {{Trotz der Annahme, dass Langzeitpraktika im Lehramts-studium hohe Belastungen für Studierende darstellen können, sind empirische Analysen zum Einfluss sozialer (z.B. die Betreuung eigener Kinder, Pflegeaufgaben) und organisationaler Bedingungsfaktoren (z.B.

Thirty‐seven participants learned a sequential arm movement with 192 trials in each of five practice sessions. Feedback, based on a performance adaptive bandwidth, was given after every trial. Electroencephalogram (EEG) was recorded in the first and last practice sessions. The degree of motor automatization was tested under dual‐task conditions in a pre‐test–post‐test design. Quantitative error information was transported in both feedback conditions (positive and negative). Frontal theta activity was discussed as a general signal that cognitive control is needed and, therefore, was expected to be higher after negative feedback. Extensive motor practice promotes automatization, and therefore, decreased frontal theta activity was expected in the later practice. Further, it was expected that frontal theta was predictive for subsequent behavioural adaptations and the amount of motor automatization. As the results show, induced frontal theta power was higher after negative feedback and decreased after five sessions of practice. Moreover, induced theta activity was predictive for error correction and, therefore, an indicator of whether the recruited cognitive resources successfully induced behavioural adaptations. It remains to be solved why these effects, which fit well with the theoretical assumptions, were only revealed by the induced part of frontal theta activity. Further, the amount of theta activity during practice was not predictive for the degree of motor automatization. It seems that there might be a dissociation between attentional resources associated with feedback processing and attentional resources associated with motor control.}}, author = {{Margraf, Linda and Krause, Daniel and Weigelt, Matthias}}, issn = {{0953-816X}}, journal = {{European Journal of Neuroscience}}, keywords = {{General Neuroscience}}, number = {{8}}, pages = {{1297--1316}}, publisher = {{Wiley}}, title = {{{Frontal theta reveals further information about neural valence‐dependent processing of augmented feedback in extensive motor practice - A secondary analysis}}}, doi = {{10.1111/ejn.15951}}, volume = {{57}}, year = {{2023}}, } @inproceedings{47125, author = {{Margraf, Linda and Krause, Daniel and Weigelt, Matthias}}, editor = {{Schott, N. and Klotzbier, T. and Korbus, H. and El-Rajab, I. and Holfelder, B. and Gomolinsky, U. and Park, S-Y.}}, location = {{Stuttgart}}, publisher = {{Stuttgart: Universität Stuttgart }}, title = {{{Frontal theta reveals further information about neural valence-dependent processing of augmented feedback in extensive motor practice.}}}, year = {{2023}}, } @article{43061, abstract = {{Purpose: The aim of this study was to examine whether cortical activity changes during exercise with increasing cognitive demands in preadolescent children. Method: Twenty healthy children (8.75 [0.91] y) performed one movement game, which was conducted with lower and higher cognitive demands. During a baseline measurement and both exercise conditions, cortical activity was recorded using a 64-channel electroencephalographic system, and heart rate was assessed. Ratings of perceived excertion and perceived cognitive engagement were examined after each condition. To analyze power spectral density in the theta, alpha-1, and alpha-2 frequency bands, an adaptive mixture independent component analysis was used to determine the spatiotemporal sources of cortical activity, and brain components were clustered to identify spatial clusters. Results: One-way repeated-measures analyses of variance revealed significant main effects for condition on theta in the prefrontal cluster, on alpha-1 in the prefrontal, central, bilateral motor, bilateral parieto-occipital, and occipital clusters, and on alpha-2 in the left motor, central, and left parieto-occipital clusters. Compared with the lower cognitive demand exercise, cortical activity was significantly higher in theta power in the prefrontal cluster and in alpha-1 power in the occipital cluster during the higher cognitive demand exercise. Conclusion: The present study shows that exercise complexity seems to influence cortical processing as it increased with increasing cognitive demands.}}, author = {{Becker, Linda and Büchel, Daniel and Lehmann, Tim and Kehne, Miriam and Baumeister, Jochen}}, issn = {{0899-8493}}, journal = {{Pediatric Exercise Science}}, keywords = {{Physical Therapy, Sports Therapy and Rehabilitation, Orthopedics and Sports Medicine, Pediatrics, Perinatology and Child Health}}, pages = {{1--11}}, publisher = {{Human Kinetics}}, title = {{{Mobile Electroencephalography Reveals Differences in Cortical Processing During Exercises With Lower and Higher Cognitive Demands in Preadolescent Children}}}, doi = {{10.1123/pes.2021-0212}}, year = {{2023}}, } @article{42717, author = {{Strotmeyer, Anne and Ortwein, Lena and Kehne, Miriam}}, journal = {{Playground@Landscape}}, number = {{1}}, pages = {{92--97}}, title = {{{Spielplatzgeräte: Potenziale zur ganzheitlichen Förderung von Heranwachsenden}}}, year = {{2023}}, } @article{47130, author = {{Güldenpenning, Iris and Jackson, Robin C. and Cañal-Bruland, Rouwen}}, journal = {{Human Movement Science}}, publisher = {{Elsevier}}, title = {{{The science of deceptive human movement}}}, doi = {{https://doi.org/10.1016/j.humov.2023.103147}}, volume = {{92}}, year = {{2023}}, } @inbook{47059, author = {{Weigelt, Matthias and Krause, Daniel and Güldenpenning, Iris}}, booktitle = {{Sport and Exercise Psychology}}, editor = {{Schüler, J. and Wegner, M. and Plessner, H. and Eklund, R.
