Evaluation of freeze-thaw wind erosion and analysis of influencing factors on the Tibetan Plateau based on the improved RWEQ

open access: yesZhongguo dizhi zaihai yu fangzhi xuebao
Freeze-thaw wind erosion refers to the process in which temperature fluctuations cause changes in the surface structure, significantly impacting on the formation of surface landform and soil properties. However, due to the particularity and complexity of

Quantification of soil erosion in the Alps : measurement and modeling [PDF]

open access: yes, 2010
Alpine regions have a high potential for soil erosion associated to extreme climatic and topographic conditions. Because of aggressive development in the recent past, environmental damage enhanced by acid deposition, global warming and development ...

Astrocytic FDX1 Contributes to Copper Dyshomeostasis‐associated Synaptic Dysfunction in Depression and Is Modulated by Exercise

open access: yesAdvanced Science, EarlyView.
Chronic stress disrupts copper homeostasis and promotes copper accumulation in the prelimbic cortex, leading to astrocytic FDX1 upregulation. Elevated astrocytic FDX1 impairs calcium signaling, induces structural atrophy, and disrupts synaptic function, contributing to depressive‐like behaviors. Physical exercise reverses these alterations by restoring

Improving rehabilitation practices for the outer batter slopes of bauxite residue disposal areas at Worsley refinery, Collie, Western Australia [PDF]

open access: yes, 2002
Control of water erosion of soil at mine sites requires an ability to predict the effects of different management practices on soil loss. Using soil loss models such as the Revised Universal Soil Loss Equation (RUSLE) requires calibration of the model ...

Bridged h‐BN Nanosheets Coatings: Simultaneous Shielding Atomic‐Oxygen Irradiation and Achieving Superior Friction Performance

open access: yesAdvanced Science, EarlyView.
ABSTRACT To confront extreme space environments, a combination of inorganic and organic coatings can provide a pathway for offering highly durable radiation resistance and anti‐friction simultaneously. Herein, a strong interfacial 3D hydrogen‐bonding network is designed to create robust hexagonal boron nitride (h‐BN) based polymer coatings with ...

Attribution and Risk Assessment of Wind Erosion in the Aral Sea Regions Using Multi-Source Remote Sensing and RWEQ on GEE

open access: yesRemote Sensing
The rapid desiccation of the Aral Sea has transformed the region into one of the world’s most severe soil wind-erosion hotspots. Despite growing concern, long-term, high-resolution assessments and driver attribution remain insufficient.

Real‐Time Stress Visualization of Hydrogels Enabled by Supramolecularly Switched Stretch‐Induced Phase Separation

open access: yesAdvanced Science, EarlyView.
Supramolecular hydrogels enable real‐time visualization of mechanical stress through supramolecular switching mechanotransduction. Adamantane‐modified cellulose functions as a responsive domain that undergoes an on–off transition between hydrated and dehydrated states via reversible β‐cyclodextrin–adamantane complexation and decomplexation.

Wind reduction patterns around isolated biomass for wind erosion control in a desertified area of Central Sudan [PDF]

open access: yes, 2010
The aim of this study was to assess the effectiveness of sparse vegetation, feature common in arid zone, to reduce wind force (velocity) and hence protect the surface and regions downwind from drifting sand and their consequences.
