The present investigation deals with the propagation of waves in a micropolar transversely isotropic layer. Secular equations for symmetric and skew-symmetric modes of wave propagation in completely separate terms are derived. The amplitudes of displacements and microrotation were also obtained. Finally, the numerical solution was carried out for aluminium epoxy material and the dispersion curv...

purpose: to compare fusional vergence amplitudes in patients with symptomatic and asymptomatic near exophoria methods: this cross-sectional study included 102 patients with near exophoria and asthenopia and 86 with asymptomatic near exophoria, all of whom were aged 15-35 years and had best corrected far visual acuity better than 20/25. far and near fusional vergence amplitudes were evaluated in...

in addition to optimal conditions, invariant laws of lorentz, parity and time reversal are imposed to find the relation between observables (spin rotation parameters) and bilinear combination of helicity amplitudes in pion-proton elastic scattering at 6.0 gev/c. by normalizing the differential cross-section to unity, the magnitudes of helicity amplitudes and the angle between them are determine...

In this study the interaction between self-excited and paramet rically excited oscillations in two-degree-of-freedom systems with quadratic nonlinearities is investigated. The fundamental parametric resonance of the first mode and 3:1 internal resonance is considered, followed by 1:2 internal and parametric resonances of the second mode. The method of multiple time scales is applied to derive f...

The effect of the slit length on acoustic transfer impedance micro-slit plates (MSPs) is investigated in linear and non-linear regime for a specific geometry. This geometry inspired by slits obtained cutting bending plate. MSPs are with arrays slit-shaped perforations, width order viscous boundary layer thickness. Impedance tube measurements two accurately manufactured compared to numerical sol...

Introduction: In this study we compared transcranial magnetic stimulation (TMS) elicited motor evoked potentials (MEPs) in a postural (bilateral low back extension: BLBE) and a respiratory (forced expiration during breath holding: FEBH) task.Methods: Using TMS of the left motor cortex, simultaneous patterns of corticospinal facilitation of the contralateral erector spinae (ES) and rectus abdomi...

Optimal conditions are used in nondynamical formalism to diagonalize the pionproton reaction matrix as much as possible. Invariance laws are imposed to simplify the relationship between observables and bilinear combination of amplitudes. Transverse amplitudes are determined by using measured polarization parameter in xfp elastic scattering at 6.0 GeVIC

several previous studies of adults have reported that the amplitudes of the sural and superficial radial nerve (sn and srn) action potentials are larger with antidromic than with orthodromic recordings. however, this difference has not been documented in children. this study evaluated the amplitudes of sn and srn sensory nerve action potentials (snaps), obtained with antidromic and orthodromic ...

The mammalian lateral geniculate nucleus seems organized to gate or control the gain of retinogeniculate transmission, the result of which is then relayed to the visual cortex. We have performed in vivo intracellular studies of retinogeniculate transmission along these retino-geniculo-cortical pathways in cats by recording the retinally evoked excitatory postsynaptic potential (EPSP) in genicul...
