Most of research projects on cyclical motor activity focus on locomotion. They provide ambivalent data on the considered theme. Saito et al. [1] present the results of their research on the relationship between step length and frequency in sprint, which was not a decreasing one. Laurent and Pailhous [2] observed that step length and frequency both correlate with walking speed but are relatively...

The object of this study was to examine the relationship between excitatory postsynaptic potential (EPSP) amplitude, posttetanic potentiation, and EPSP amplitude modulation at synapses made by group Ia afferents on motoneurons in the rat. These relationships were evaluated in cells in untreated rats and in cells in rats treated with the gamma-aminobutyric acid-B (GABAB) receptor agonist baclofe...

the interactive effects of adjacent buildings on their seismic performance are not frequently considered in seismic design. the adjacent buildings, however, are interrelated through the soil during seismic ground motions. the seismic energy is redistributed in the neighboring buildings through multiple structure-soil-structure interactions (sssi). for example, in an area congested with many nea...

The aim of this study was to determine the most suitable shaking frequency and amplitude for shake harvesting lime fruit (C. aurantifolia). A tractor mounted limb shaker with adjustable shaking frequency and amplitude, powered by the tractor power-take-off shaft was designed and developed for this study. The rotating input power was transmitted to the shaker flywheel through a multiple sheave v...

this paper proposes a new method for parameter estimation of distorted single phase signals, through an improved demodulation-based phase tracking incorporated with a frequency adaptation mechanism. the simulation results demonstrate the superiority of the proposed method compared to the conventional sogi (second-order generalized integrator)-based approach, in spite of the dc-offset and harmon...

background and aim: the normal response of h-reflex depression (hd) was reduced in chronic spinal cord injury (sci) patients. the reduction of this normal response can lead to increase the muscle tone and spasticity. the purpose of this study is to investigate the effect of tripolar cathodal stimulation on hd in sci patients.   materials and methods: this study was conducted in 10 volunteered s...
