Cat papillary muscles were tetanized with repetitive electrical stimulation in the presence of 10 ITIM caffeine and 10 mM calcium. Velocities were measured during the plateau of tetanus with quick releases to isotonic loads. The course of isotonic shortening was independent of time in the contraction cycle for at least 2 seconds after the attainment of peak isometric force. The force-velocity r...

We determine the Compton effect from the Volkov solution of the Dirac equation for a process in medium with the index of refraction n. Volkov solution involves the mass shift, or, the mass renormalization of an electron. We determine the modified Compton formula for the considered physical situation. The index of refraction causes that the wave lengths of the scattered photons are shorter for s...

Experiments show that the optical reflectance of a random medium can have a nonmonotonic dependence on wavelength even when its absorption spectrum is flat and its scattering coefficient decreases monotonically with wavelength. Measured at a particular radial distance from the illumination point, the reflectance is almost independent of wavelength over a wide band. The peak wavelength of the re...

styrene polymerization through frp and atrp methods was carried out at 110oc, while in-depth studies were performed by monte carlo simulation.the changes in monomer conversion, initiator concentration, average molecular weight, and polydispersity index were computed over the course of the polymerization. as the results indicate, compared to atrp, the frp reaches higher conversion in a similar r...

which describes a static, planar domain wall stretched along the x = 0 plane. Here Φ0 = M/(2 √ λ) denotes one of the two vacuum values of the field Φ — the other one is equal to −Φ0. The parameter M can be identified with the mass of the scalar particle related to the field Φ. The corresponding Compton length l0 = M −1 gives the physical length scale in the model. Energy density for the planar ...

VLA observations of large-scale HI and OH absorption in the merging galaxy of NGC6240 are presented with 1 arcsec resolution. HI absorption is found across large areas of the extended radio continuum structure with a strong concentration towards the double-nucleus. The OH absorption is confined to the nuclear region. The HI and OH observations identify fractions of the gas disks of the two gala...

In this paper, a Green’s function is developed for bending analysis of micro plates under an asymmetric load. In order to consider the length scale effect, the modified couple stress theory is used. This theory can accurately predict the behavior of micro structures. A thin micro plate is considered and therefore the classical plate theory is utilized. The size dependent governing equilibrium e...

Jalbert, Neath, Bireta, and Surprenant (2011) suggested that past demonstrations of the word length effect, the finding that words with fewer syllables are recalled better than words with more syllables, included a confound: The short words had more orthographic neighbors than the long words. The experiments reported here test two predictions that would follow if neighborhood size is a more imp...
