Contact of working surfaces for spherical washers and recommendations for determining the gap in the joint by Dehtiarov I. M., Neshta A. O., Samardak M. P., Antosz K., Avramenko S. E.

“…In the article was proposed to introduce into the technical requirements for the spherical washers drawings changes concerning the gap size allowable in the conjunction, and as well as tolerances value changes of the radii of the working surfaces of the washers, thus increasing their manufacturability without conflicting with the requirements of the current standards.…”

Community centres in increasingly diverse neighbourhoods by Eveline Althaus, Liv Christensen

“…However, individualisation and pluralisation processes, the aging of the facilities and built structures, and economic pressures pose challenges for the community centres. The current Covid-19 crisis reinforces these challenges by limiting and impeding cultural activities and direct (physical) social encounters. …”

Dissolved organic carbon and microplastics decrease the biodiversity effect on resource use efficiency of crustacean zooplankton by Yongchao Peng, Ninghui Xu, Haojie Su, Qingyang Rao, Chaoyue Cheng, Jun Chen, Xinli Wen, Ping Xie

“…Our results suggested that biodiversity effects on ecosystem functioning could be probably reduced in the current global environment change context, indicating that we may underestimate the negative impact of diversity loss on ecosystem functions and services. …”

Influence of white etching layer on rolling contact behavior at wheel-rail interface by Qinglin Lian, Guanyu Deng, Hongtao Zhu, Huijun Li, Xi Wang, Zhiming Liu

“…Stress changes along the rail depth matched with the previously reported microstructure evolutions. The current work revealed that the maximum difference in contact stress between the wheel passages of rail matrix and the WEL region (noted as stress variation) rises with the increase of loading pressure, the value of a/b, and Sr; but drops with the friction coefficient (μ). …”

Contact Resistance between Calcareous Sand and Electrodes Based on the Two-Electrode Method by Weikang Wan, Heying Hou, Tianxiang Li, Binghui Wang, Pengming Jiang, Aizhao Zhou

“…The results show that the larger the particle size and relative density are, the greater the contact resistance. The contact resistance decreases with an increasing current frequency, and the decreasing amplitude decreases with an increasing saturation. …”

Influence of aerodynamic parameters of current collector on current collection at movement speeds up to 160 km/h by N. V. Mironos, M. N. Emel’yanova, D. V. Tartynskiy

“…This article investigates the influence of the aerodynamic parameters of the current collector on the contact force. For this purpose, the influence in the speed range up to 160 km/h on the quality of the current collection, in particular on the increased wear of the current collector contact strips, was determined.Materials and methods. …”

Optimization of Poly-Si/SiOx Passivated Contacts for Crystalline Silicon Bottom Cells Applications by Julci Ditsougou, Thibaut Desrues, Anne Kaminski, Sébastien Dubois

“…Moreover, these thicker poly-Si layers benefit more from hydrogenation steps, enabling i-Voc of around 720 mV and carrier lifetimes of up to 5 ms on cell precursors. Finally, while increasing the thickness leads to current limitation under AM1.5G (1 Sun) illumination, this limitation is less pronounced under IR illumination. …”
