The major regulatory factors in the mesenteric circulation include general hemodynamic forces, the autonomic nervous system, circulating vasoactive substances, tissue metabolites and intrinsic characteristics of vascular smooth muscle. During mesenteric ischemic states smooth muscle spasm elevates resistance to blood flow and aggravates intestinal tissue hypoxia leading to mucosal necrosis. Clo...

We overview recent results on intrinsic frictional properties of adsorbed monolayers, composed of mobile hard-core particles undergoing continuous exchanges with a vapor phase. In terms of a dynamical master equation approach we determine the velocity of a biased impure molecule-the tracer particle (TP), constrained to move inside the adsorbed monolayer probing its frictional properties, define...

We study whether or not sine-Gordon kinks exhibit internal modes or "quasimodes." By considering the response of the kinks to ac forces and initial distortions, we show that neither intrinsic internal modes nor "quasimodes" exist in contrast to previous reports. However, we do identify a different kind of internal mode bifurcating from the bottom edge of the phonon band which arises from the di...

The rheological behaviour of soft glassy materials results essentially from the interplay between shearing forces and an intrinsic slow dynamics. This competition can be described by a microscopic theory, which can be viewed as a nonequilibrium schematic mode-coupling theory. This statistical mechanics approach to rheology results in a series of detailed theoretical predictions, some of which a...

When an object is lifted vertically, the normal force increases and decreases in tandem with tangential (load) force to safely avoid slips. For horizontal object transport, horizontal forces at the contact surfaces can be decomposed into manipulation forces (producing acceleration/deceleration) and grasping forces. Although the grasping forces must satisfy equilibrium constraints, it is not cle...

We derive and numerically solve a surface active nematodynamics model. validate the numerical approach on sphere analyse influence of hydrodynamics oscillatory motion topological defects. For ellipsoidal surfaces geometric forces these patterns is addressed by taking into account effects intrinsic as well extrinsic curvature contributions. The experiments demonstrate stronger coupling with prop...

Background. Several researchers have studied the effects of type of feedback on learning motor skills, but there are few studies on the interaction between personality traits and the type of feedback. Objectives. This study aimed at investigating the effect of type of feedback on intrinsic motivation and learning volleyball jump serve in students with neuroticism. Methods. A total of 59 femal...

Finger-pressing forces are produced by activation of the intrinsic hand muscles, which are finger specific, and the extrinsic muscles that connect to multiple fingers. We tested a hypothesis of greater weakening of intrinsic hand muscles with age and quantified associated indexes of finger interaction such as enslaving (force production by unintended fingers) and force deficit (loss of finger f...

42 The regulation of forces is integral to motor control. However, it is unclear how 43 information from sense organs that detect forces at individual muscles or joints is 44 incorporated into a frame of reference for motor control. Campaniform sensilla are 45 receptors that monitor forces by cuticular strains. We studied how loads and muscle 46 forces are encoded by trochanteral campaniform se...
