The development of immiscible viscous fingering patterns in a rotating Hele-Shaw cell is investigated. We focus on understanding how the time evolution and the resulting morphologies are affected by the action of the Coriolis force. The problem is approached analytically and numerically by employing a vortex sheet formalism. The vortex sheet strength and a linear dispersion relation are derived...

The Yokogawa Group has developed the ROTAMASS 3 series Coriolis flow and density meters. A Coriolis flowmeter can directly measure mass flow of fluid regardless of its temperature and pressure. The ROTAMASS 3 series meters have such unique features as fast signal processing, anti-vibration mechanism, and high accuracy density measurement. This paper describes these features and applications of ...

Cosmology stands at a critical juncture. Over ve years, microwave background experiments will map in exquisite detail the properties of density uctuations three hundred thousand years after the big bang. Large-scale structure surveys will characterize both the properties of galaxies and their large scale distribution. In many ways, the outstanding problem in cosmology is understanding how the t...

1. Reaching movements made in a rotating room generate Coriolis forces that are directly proportional to the cross product of the room's angular velocity and the arm's linear velocity. Such Coriolis forces are inertial forces not involving mechanical contact with the arm. 2. We measured the trajectories of arm movements made in darkness to a visual target that was extinguished at the onset of e...

– We present a theoretical and experimental analysis of the transverse monopole mode of a fast rotating Bose-Einstein condensate. The condensate’s rotation frequency is similar to the trapping frequency and the effective confinement is only ensured by a weak quartic potential. We show that the non-harmonic character of the potential has a clear influence on the mode frequency, thus making the m...

<abstract><p>In the present paper, we study a multiscale limit for barotropic Navier-Stokes system with Coriolis and gravitational forces, vanishing values of Mach, Rossby Froude numbers ($ {\rm{Ma}} $, $ {\rm{Ro}} {\rm{Fr}} respectively). The focus here is on effects gravity: albeit remaining in low stratification regime {\rm{Ma}}/{\rm{Fr}}\, \rightarrow\, 0 consider scaling number...

Choosing a career within the military has many positive and negative factors associated with it. For instance, many recruits join as young adults when they are beginning to shape their own values, beliefs and attitudes about their self, world and others. The armed forces (AF) culture socialises these young adults, leading them to adopt military values and ideals as their own which they will pro...
