The volume contraction in dissipative reversible transitive Anosov flows obeys a large deviation rule (fluctuation theorem).

It is well established that the degree of airway smooth muscle shortening produced by a given dose of bronchial agonist is greatly affected by lung volume. The airways are tethered by parenchymal attachments, the tension of which increases progressively with lung volume, thereby presenting a commensurately increasing hindrance to smooth muscle contraction. Earlier studies (P. F. Dillon, M. O. A...

Coronary arterial inflow is impeded and venous outflow is increased as a result of the decrease in coronary vascular volume due to cardiac contraction. We evaluated whether cardiac contraction is influenced by interfering with the changes of the coronary vascular volume over the heart cycle. Length-tension relationships were determined in Tyrode-perfused rat papillary muscle and when coronary v...

Volume change and pressure development in muscle during contraction. 1967.-Volume changes recorded in isometric and isotonic twitches of gastrocnemius muscle are similar to those recorded in sartorius muscle. The major differences are the greater difficulty in approaching isometric recording conditions in the gastrocnemius muscle and the possibility that a portion of the volume change could be ...

Volume changes in the spleens of hooded seals (Cystophora cristata) and harp seals (Phoca groenlandica) were measured plethysmographically in vitro in response to epinephrine, norepinephrine, isoprenaline, phentolamine, and acetylcholine. Dilated spleens contracted forcefully within 1-3 min of alpha-adrenoceptor activation with 1.0-5.0 micrograms epinephrine/kg body mass, whereas stimulation of...

Abstract This paper presents selected numerical simulations performed using Johnson–Segalman model with specific setting of the convected derivative resulting in shear-thinning behavior model. The results are compared generalized Oldroyd-B model, which is typically used to simulate viscoelastic flows. Both models solved an in-house finite-volume solver on structured grid simulating steady flow ...

A new finite volume method for solving the incompressible Navier–Stokes equations is presented. The main features of this method are the location of the velocity components and pressure on different staggered grids and a semi-Lagrangian method for the treatment of convection. An interpolation procedure based on area-weighting is used for the convection part of the computation. The method is app...

muscle fatigue assessment has been the basis of numerous studies, specifically, in neuromuscular rehabilitation and the applications of fessystems. various emgbased techniques, in time and frequency domains, have been investigatedover years for the detection and evaluationof this phenomenon. the main objective of this study has beento evaluate the efficiency of applying a number of techniques w...
