- 摘要：
- boulevard, Tarzana, 4-H member. Five calves were released. Ten youngsters had chance to catch them and drag across white lines. Five who did won calves. 21/22
Data from: Inference of facultative mobility in the enigmatic Ediacaran organism Parvancorina
- 负责人：
- DOI：
- doi:10.5061/dryad.2601h
- 摘要：
- also demonstrate that the amount of drag varied with orientation, indicating that Parvancorina would have greatly benefited from adjusting its position
Diary of Arthur Oram;;Hely's scribbling diary for 1903

- 摘要：
- nny and Ballygurney and the assistance they required to 'drag the machine' back to Mulranny (19 October 1903). - Describes the atmosphere in the rent office in Newport
Data from: Birds land reliably on complex surfaces by adapting their foot-surface interactions upon contact

- DOI：
- doi:10.5061/dryad.89rr53h
- 摘要：
- with probabilistic friction from their claws, which they drag to find surface asperities—dragging further when they can squeeze less. Remarkably, parrotlet claws
Data from: Three-dimensional simulation for fast forward flight of a calliope hummingbird
- 负责人：
- DOI：
- doi:10.5061/dryad.8ch1b
- 摘要：
- to overcome drag on the body, and such thrust production comes at price of negative lift induced during upstroke. This feature might be shared with bats
Data from: How to find home backwards? Locomotion and inter-leg coordination during rearward walking of Cataglyphis fortis desert ants
- 负责人：
- DOI：
- doi:10.5061/dryad.7k82t
- 摘要：
- in a normal forward-faced orientation, they will drag the load walking backwards to their home nest. A detailed examination of this behaviour reveals
Data from: Clap-and-fling mechanism in a hovering insect-like two-winged flapping-wing micro air vehicle
- 负责人：
- DOI：
- doi:10.5061/dryad.28713
- 摘要：
- with the force without the clap-and-fling effect. In the CFD simulation, the clap and flings enhanced the vertical force by 11.5% and horizontal drag force by 18
Data from: Nonlocal rheology of dense granular flow in annular shear experiments
- 负责人：
- DOI：
- doi:10.5061/dryad.693kt2j
- 摘要：
- of model parameters is able to capture the full range of data collected once we account for frictional drag with the bottom plate. Our measurements confirm
Data from: How body torque and Strouhal number change with swimming speed and developmental stage in larval zebrafish
- 负责人：
- DOI：
- doi:10.5061/dryad.r503m
- 摘要：
- with adults, larval fish experience relatively high (mainly viscous) drag during cyclic swimming. To enhance thrust to an equally high level, they must employ

- 摘要：
- pharyngeal filter feeding. The results demonstrate that an orientation with the mouth facing downstream of the current was optimal for drag and lift reduction
