Debris development in fretting contacts – Debris particles and debris beds [PDF]
Tribology International, 2020 In this study, the formation and destruction of compacted beds of oxidized debris particles are investigated. Fretting tests of steel specimens were conducted, employing a cylinder-on-flat geometry with displacement amplitude being varied. The debris was examined, both in the form of the debris beds and in the form of loose debris; together, these were

Orbital debris–debris collision avoidance [PDF]
Advances in Space Research, 2011 We focus on preventing collisions between debris and debris, for which there is no current, effective mitigation strategy. We investigate the feasibility of using a medium-powered (5 kW) ground-based laser combined with a ground-based telescope to prevent collisions between debris objects in low-Earth orbit (LEO).

Simple ΔV Approximation for Optimization of Debris-to-Debris Transfers
Journal of Spacecraft and Rockets, 2021 A method for the rapid estimation of transfer costs for the removal of debris in low Earth orbit is proposed. Debris objects among a population with similar inclination values are considered. The proposed approximate analysis can provide estimations of actual Deltav between any debris object pair as a function of time; these estimations allow for the ...

CoSMO, 2023 Thinking about modernist urbanism as a period in architecture with potential for the future of cities has been outside the canon for several decades. But from a critical viewpoint, the postmodern stance on modernist mass housing continuously failed to dissociate high modernist urbanism as a unified architectural project from its socio-political ...

Plastic debris in lakes and reservoirs [PDF]
Nature, 2023 Plastic debris is thought to be widespread in freshwater ecosystems globally1. However, a lack of comprehensive and comparable data makes rigorous assessment of its distribution challenging2,3. Here we present a standardized cross-national survey that assesses the abundance and type of plastic debris (>250 μm) in freshwater ecosystems.

Plastic debris in the open ocean [PDF]
Proceedings of the National Academy of Sciences, 2014 Significance High concentrations of floating plastic debris have been reported in remote areas of the ocean, increasing concern about the accumulation of plastic litter on the ocean surface. Since the introduction of plastic materials in the 1950s, the global production of plastic has increased rapidly and will continue in the coming decades.

Monitoring litter and microplastics in Arctic mammals and birds
Arctic Science, 2022 Plastic pollution has been reported to affect Arctic mammals and birds. There are strengths and limitations to monitoring litter and microplastics using Arctic mammals and birds.
