Giant convecting mud balls of the early solar system
Carbonaceous asteroids may have been the precursors to the terrestrial planets, yet despite their importance, numerous attempts to model their early solar system geological history have not converged on a solution. The assumption has been that hydrothermal alteration was occurring in rocky asteroids with material properties similar to meteorites. However, these bodies would have accreted as a h...
متن کاملArmored Mud Balls ' Their Origin , Properties , and in Sedimentation
.\BSTR.\ CT A brief summary of the limited literature devoted to mud balls centers around nomenclature, the ideas regarding the origin of mud balls, and the factors limiting their size. A report is made of a combined field and laboratory study in which an investigaticn of the size which mud balls may attain leads to conclusions that differ from those in the literature; findings are presented wh...
متن کاملBalanced Allocations: Balls-into-Bins Revisited and Chains-into-Bins
The study of balls-into-bins games or occupancy problems has a long history since these processes can be used to translate realistic problems into mathematical ones in a natural way. In general, the goal of a balls-into-bins game is to allocate a set of independent objects (tasks, jobs, balls) to a set of resources (servers, bins, urns) and, thereby, to minimize the maximum load. In this paper ...
متن کاملNonspherical armoured bubble vibration.
In this paper, we study the dynamics of cylindrical armoured bubbles excited by mechanical vibrations. A step by step transition from cylindrical to spherical shape is reported as the intensity of the vibration is increased, leading to a reduction of the bubble surface and a dissemination of the excess particles. We demonstrate through energy balance that nonspherical armoured bubbles constitut...
متن کاملArmoured fighting vehicle injuries in peacetime.
A year-long prospective study of injuries caused by armoured fighting vehicles on exercises in West Germany revealed that 2 soldiers were killed. Another 41 needed hospital admission for treatment of injuries of the lower limb (16), upper limb (15), head (8) and back (2). Tank loader/signallers were peculiarly susceptible to severe leg injuries, due to the ankle being trapped and twisted by the...
