We performed ball-on-disc tests at different values of residual humidity, in pure oxygen atmosphere and at different temperatures, in order to disentangle the role of water and molecular oxygen during sliding.
Withering was also associated with during-work declines in pulmonary function, which might be due to the fact that some workers had performed ball-rolling or panning before the tests.
Evidence supports that girls are less proficient than boys at performing ball skills.
Limitations were related to sport activities (n = 12), in particular performing ball sports, push-ups, and other bimanual activities that required strength.
Three similarly performing balls would be the Bridgestone e6+ ($25), the Titleist NXT Tour ($30) and the TaylorMade Burner TP ($25).
Dry sliding wear resistance of samples was determined by performing ball-on-disc wear testes.
You may want to consider wearing protective eyewear, such as sports goggles, when performing ball-throwing exercises.
A set of ball-on-disc experiments is performed, with ball materials being nylon, steel and ceramic, on hard steel disc material.
Badylak et al. repaired surgically created abdominal wall defects in dogs with SIS (8 × 12 cm); they performed serial ball burst strength tests after 1, 4, 7, and 10 days and then at 1, 3, 6, and 24 months) [ 52].
Reciprocating ball on disc tests was performed, using balls with two different surface roughnesses.
