Deep carbon cycle constrained by carbonate solubility

Nature Communications, 2021
Carbonate mineral aqueous solubility decreases as carbonates become more Mg-rich during subduction. Coupled with regional variations in amounts of carbon and water subducted, this explains discrepancies in estimates of carbon recycling, suggesting that ...

Orbital dynamics of earth-orbiting 'smart dust' spacecraft under the effects of solar radiation pressure and aerodynamic drag [PDF]

, 2010
This paper investigates how the perturbations due to asymmetric solar radiation pressure, in presence of Earth's shadow, and atmospheric drag can be balanced to obtain long-lived Earth centered orbits for swarms of SpaceChips, without the use of active ...

Lateral earth pressure on rigid retaining walls with EPS deformable geofoam inclusions

Yantu gongcheng xuebao, 2019
The finite difference program, FLAC3D, is used to model the rigid retaining wall with EPS (expanded polystyrene) deformable geofoam inclusions, and the lateral earth pressure on the wall is obtained from numerical results. The at-rest state, active state

Therapeutic Apheresis in Nigeria: A Multi‐Center Summary of Abstracts From the Inaugural Nigerian Society for Apheresis Scientific Meeting

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Reactive formation of magnesiowüstite at the lunar core-mantle boundary

Nature Communications
Seismological and geodetic data indicate that the lunar core-mantle boundary (CMB) exhibits a well-defined low-velocity zone (LVZ) with a combination of anomalous seismic velocities and density that remain unexplained.

Earth pressure and stability of deep arch tunnel with straight wall in cohesive strata

Yantu gongcheng xuebao, 2017
The limit analysis method is adopted to study deep arch tunnel with straight wall in cohesive strata based on the shear failure theory. Firstly, a theoretical model for ruptured zone in the deep arch tunnel is established based on loading tests. And then

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.
