Scaling forces to asteroid surfaces: The role of cohesion
0019-1035/$ see front matter 2010 Elsevier Inc. A doi:10.1016/j.icarus.2010.07.009 * Corresponding author. E-mail address: [email protected] (D.J. Schee The scaling of physical forces to the extremely low ambient gravitational acceleration regimes found on the surfaces of small asteroids is performed. Resulting from this, it is found that van der Waals cohesive forces between regolith grain...
متن کاملUnit cohesion and mental health in the UK armed forces.
BACKGROUND Unit cohesion is recognized as a potentially modifiable factor in the aetiology of mental illness among military personnel. AIMS To examine the association between unit cohesion and probable post-traumatic stress disorder (PTSD), common mental disorder and alcohol misuse, in UK armed forces personnel deployed to Iraq. METHODS A sample of 4901 male UK armed forces personnel who ha...
متن کاملQuantitative estimate of the paleo-Agulhas leakage
The Indian-Atlantic water exchange south of Africa (Agulhas leakage) is a key component of the global ocean circulation. No quantitative estimation of the paleo-Agulhas leakage exists. We quantify the variability in interocean exchange over the past 640,000 years, using planktic foraminiferal assemblage data from two marine sediment records to define an Agulhas leakage efficiency index. We conf...
متن کاملOn the initial estimate of interface forces in FETI methods
The Balanced Domain Decomposition (BDD) method and the Finite Element Tearing and Interconnecting (FETI) method are two commonly used non-overlapping domain decomposition methods. Due to strong theoretical and numerical similarities, these two methods are generally considered as being equivalently efficient. However, for some particular cases, such as for structures with strong heterogeneities,...
متن کاملQuantitative assessment of dynamic control of fingertip forces after pollicization.
Dexterity after finger pollicization (reconstruction to thumb) is critical to functional outcomes. While most tests of hand function evaluate a combination of strength, coordination, and motor control, the Strength-Dexterity (S-D) paradigm focuses on the dynamic control of fingertip forces. We evaluated 10 pollicized and 5 non-pollicized hands from 8 participants ages 4-17 years (2 female, 6 ma...
