ABSTRACT The webbed foot structure of mallards (Anas platyrhynchos) exhibits effective anti-subsidence properties when walking on soft ground. To investigate the effects of quartz sand particle size and thickness on joint angles and the movement patterns of webbed feet, we created a testing substrate with quartz sand and utilized high-speed cameras and …

ABSTRACT In this study, a superconducting high gradient magnetic separation (S-HGMS) technology was used to separate and extract quartz from sea sand. Under optimal conditions (i.e., a magnetic flow ratio of 0.085 T·s/m, slurry flow velocity of 400 ml/min, and pulp concentration of 40 g/L), the SiO2 grade increased from 79.45% of the raw material to 91.35% …

Moreover, the internal friction angle of carbonate sand is more than that of quartz sand. Quartz sand is more affected by initial relative density, whereas, carbonate sand is influenced by inherent packing. Keywords: Carbonate sand, Quartz sand, Shear behavior, Triaxial test.

Sandpaper consists of fine particles from either natural or synthetic sources. The particles (also known as grains or grit) are sifted through screens and sorted by size before being bonded with adhesive to a paper, sponge, or cloth-type backing to create an abrasive material. In the United States, grit is determined based on …

Soil-filled wire and geotextile gabions are commonly used to construct defensive infrastructure in military bases, where the attenuating properties of soil are used to protect personnel and key assets from the effects of blast and fragmentation. The behaviour of soils in these extreme loading regimes is not well understood, and so designers require data at these …

The commonly used ratios of the training datasets to testing datasets are 0.7:0.3, 0.85:0.15, 0.9:0.1. In this paper, we adopted the split ratio of 0.85:0.15, which was also used by many other authors (e.g., Wu et al., 2022, Qing and Niu, 2018). For each LBS particle, 30 point subsets were generated, in which 26 point subsets were used as the ...
