Indeed, in many experiments the 1×g reference centrifuge on board revealed the same data as the 1×g controls on ground, proving the lack of gravity was causing the results. In other cases, the reference centrifuge data were intermediate or clearly different to the ground data which was ...
The chemical composition, particle morphology, particle size distribution, specific gravity, maximum and minimum densities, and shear strength parameters have been determined. These parameters can be seen as standard metrics in the characterisation of planetary regolith simulants or analogues. The obtained...

When the inclination angle is small, the bale is stationary on the inclined surface, and the friction force at this time is the static friction force [18]. Varying the magnitude of θ, the equation of motion of the bale rolling along the inclined plane under the action of gravity, support...
A Nucleodur C-18 gravity 150 × 4.6 mm (5 μm) column was used for the quantitative determination of pesticide residues. Analytical standards of high purity were used for establishing linearity and linear range, and repeatability and accuracy of the analytical method. The analytical standard of ...
maximum value when the yaw angle was 90° with feathered blades, while the tower vibration response in the side–side direction was relatively severe with the yaw angle ranging from 10° to 50°. These observations are found to be well aligned with the aerodynamic characteristics of the airfoil...
The effects of the blunt body structure parameters and the center spacing ratio on the energy harvesting performance of the system are qualitatively explained by constructing a simulation model. Compared with the single blunt body energy capture structure, the side-by-side double blunt body structure...
