We hypothesized that local contact forces between the pericardium and the heart cause regional variation in pericardial deformation during the cardiac cycle, reflecting volume changes of the underlying cardiac chambers. To test this, we measured regional pericardial area over the right atrium (RA) and right ventricle (RV) with orthogonal pairs of sonomicrometers in six open-chest dogs. At a lef...

Over the last decade, ecosystem management has been tending toward understanding ecosystems as having multiple stable states. Often such states are characterised as socially desirable and undesirable, with for instance high/low fish stocks or oligotrophic/eutrophic lake states. Their significance is that small stochastic forces may force the system over a threshold toward an alternative, potent...

All is not equal Theory suggests that market forces should bring the relative pay of skilled workers into line in different regions within a country. that this is not the case for the UK and argue that regional industrial policy needs to take this into account.

This paper identifies some of the forces that influence the impact of air transportation on regional connectivity and economic productivity in the United States. In light of recent threats to the financial viability of the airline industry, a conceptual model has been developed to highlight the interdependence of the national economy and the air transportation system. These complex relationship...

Nayak et al have discussed in detail the inertial forces such as Gravitational, Coriolis-Lense-Thirring and Centrifugal forces in the Kerr-Newman Space-time in the Kerr-Newman Space-time. The main theme of this paper is to study the Gravitational and Centrifugal forces in the NUT-Kerr-Newman Space-time. Keywords—Gravitational Forces, Centrifugal Forces, Nut-KerrNewman, Space time.

and James F. Lutsko Physics Department CP 231 Université Libre de Bruxelles Blvd. du Triomphe, 1050 Brussels, Belgium Abstract Many recent papers have questioned Irving and Kirkwood’s atomistic expression for stress. In Irving and Kirkwood’s approach both interatomic forces and atomic velocities contribute to stress. It is the velocity-dependent part that has been disputed. To help clarify this...

Traditional mobile phones have been used for alerting purposes by utilizing their SMS and cell broadcasting features. They do however not suit for demanding alerting and command purposes, for the observation of special forces, rescue officers and civilians, or for the post-evaluation of the operation. Current 3G and 4G/LTE smartphones can do all this, but the empirical evidence is missing. This...

Ines M. Hübler Department of General Engineering, University of Illinois at Urbana-Champaign, Urbana, Illinois 61801 (Dated: November 28, 2004) Abstract When an isotropic object is accelerated by plane waves, its limiting speed is less or equal to the wave speed. We study the acceleration of anisotropic objects in classical wave-particle systems. We investigate objects with anisotropic mass dis...

In models of economic geography, plant-level scale economies and trade costs create incentives for spatial agglomeration of production into a manufacturing core and agricultural periphery, creating regional income differentials. We examine tax competition between national governments to influence the location of manufacturing activity. Labour is imperfectly mobile and governments impose redistr...
