BACKGROUND The trapeziometacarpal joint is subjected to high compressive forces during powerful pinch and grasp tasks due to muscle loading. In addition, muscle contraction is important for stability of the joint. The aim of the present study is to explore if different muscle activation patterns can be found between three functional tasks. METHODS Isometric forces and fine-wire electromyograp...

The mechanisms that govern the voluntary transition from walking to running as walking speed increases in human gait are not well understood. The objective of this study was to examine the hypothesis that plantar flexor muscle force production is greatly impaired at the preferred transition speed (PTS) due to intrinsic muscle properties and, thus, serves as a determinant for the walk-to-run tra...

The pyloric mucosa and the gastric and intestinal juices of the dog were found to contain two cobalaminbinding proteins which have been identified as intrinsic factor and R binder. T h e ileal mucosa also contains unsaturated R binder and, in addition, a specific receptor protein which couples the intrinsic factormcobalamin complex. This receptor protein was solubilized using mechanical sharing...

A number of innovative methods exist to measure cell-matrix adhesive forces, but they have yet to accurately describe and quantify the intricate interplay of a cell and its fibrous extracellular matrix (ECM). In cardiovascular pathologies, such as aortic aneurysm, new knowledge on the involvement of cell-matrix forces could lead to elucidation of disease mechanisms. To better understand this dy...

The Torsion Pendulum Basic Properties The torsion pendulum has the useful property of being able to detect small differences in forces exerted on a body. To understand the mechanism behind this, consider a bar with two different bodies attached to either end hanging from a thin fiber. If parallel, equal forces are exerted on both test bodies, we expect to see no resulting torque on the device, ...

Fluid dynamics in intrinsically curved geometries is encountered in many physical systems in nature, ranging from microscopic bio-membranes all the way up to general relativity at cosmological scales. Despite the diversity of applications, all of these systems share a common feature: the free motion of particles is affected by inertial forces originating from the curvature of the embedding spac...

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...
