abstract   introduction: the purpose of present research was the study of the effect of sensory feedback on speed of the relative phase transition in anti-phase bimanual coordination pattern across old adults. materials and methods: therefore 15 intact male old adults selected in available with age range 60-70 years that were all of them hand-right. participants started their movement on bimanu...

OBJECTIVE Accurate and reproducible coil positioning is important for headache research using transcranial magnetic stimulation protocols. We aimed to design a transcranial magnetic stimulation coil holder and demonstrate reliability of test-retest coil positioning. METHODS A coil holder was developed and manufactured according to three principles of stability, durability, and three-dimension...

an experimental study of the phase inversion behavior of liquid-liquid dispersion has been conducted in a spray extraction column for systems of toluene / water, n-hexane/water, ccl4/water, toluene /water + glycerol (25 % wt), toluene + ccl4 (25 % wt) / water and toluene / acetic acid (5 % wt)/water. the effects of physical properties, mass transfer and column geometry on phase inversion have b...

this paper addresses the annealing temperature effect on nanostructure and phase transition of copper oxide thin films, deposited by pvd method on glass substrate (at 110 nm thickness) and post annealed at different temperatures (200-400°c) with a flow of 1 cm3s-1 oxygen. the x-ray diffraction (xrd) was employed for crystallographic and phase analyses, while atomic force microscopy (afm) was us...
