Solid particle erosion and viscoelastic properties of thermoplastic polyurethanes [PDF]

open access: yes, 2015
The wear resistance of several thermoplastic polyurethanes (TPUs) having different chemical nature and micronscale arrangement of the hard and soft segments has been investigated by means of erosion and abrasion tests.

A scenario of planet erosion by coronal radiation [PDF]

open access: yes, 2009
Context: According to theory, high-energy emission from the coronae of cool stars can severely erode the atmospheres of orbiting planets. No observational tests of the long term effects of erosion have yet been made.

Erosive arthritis [PDF]

open access: yesArthritis Research & Therapy, 2007
Inflammation and degradation of bone are two closely linked processes. Chronic inflammatory arthritis not only leads to inflammatory bone loss but it also involves local erosion of articular bone. This osteo-destructive feature of chronic inflammatory arthritis is a major cause of disability in patients with rheumatoid arthritis.

Global long-term observations of coastal erosion and accretion

open access: yesScientific Reports, 2018
Changes in coastal morphology have broad consequences for the sustainability of coastal communities, structures and ecosystems. Although coasts are monitored locally in many places, understanding long-term changes at a global scale remains a challenge ...

Enrichment of organic carbon in sediment transport by interrill and rill erosion processes [PDF]

open access: yes, 2008
Erosion and loss of organic carbon (OC) result in degradation of the soil surface. Rill and interrill erosion processes on a silt loam soil were examined in laboratory rainfall and flume experiments.

Assessment of the Permanent Gully Morphology Measurement by Unmanned Aerial Vehicle Photogrammetry with Different Flight Schemes in Dry–Hot Valley of Southwest China

open access: yesDrones
Unmanned Aerial Vehicle (UAV) photogrammetry technique offers significant potential for generating highly detailed digital surface models (DSM) of gullies. However, different flight schemes can considerably influence measurement accuracy.

Effects of Driving Factors on Forest Aboveground Biomass (AGB) in China’s Loess Plateau by Using Spatial Regression Models

open access: yesRemote Sensing, 2022
Forests are the main body of carbon sequestration in terrestrial ecosystems and forest aboveground biomass (AGB) is an important manifestation of forest carbon sequestration.

Shifts in soil nutrient concentrations and C:N:P stoichiometry during long-term natural vegetation restoration [PDF]

open access: yesPeerJ, 2020
Background Ecological stoichiometry (C:N:P ratios) in soil is an important indicator of the elemental balance in ecological interactions and processes.

Application of an Ultrasonic Sensor to Monitor Soil Erosion and Deposition [PDF]

open access: yes, 2020
While erosion and deposition are naturally occurring processes, these processes can be accelerated by human influences. The acceleration of erosion causes damage to human assets and costs billions of dollars to mitigate.

Estimating soil degradation in montane grasslands of North-eastern Italian Alps (Italy) [PDF]

open access: yes, 2019
Grasslands cover a large portion of the terrestrial ecosystems, and are vital for biodiversity conservation, environmental protection and livestock husbandry.
