摘要:Sedimentary rocks in the Ostrava-Karviná Coalfield (OKR) especially the Saddle Seams of the Karviná Formation are marked with considerable abrasive property following from the high content of siliceous component in these rocks. In these conditions drilling, using the classic...

摘要:Like an ideal model of the bumps rise is possible to create for the OKR saddle layers seams conditions on the base of analyses of oscillation effects resp. drifts using roofs of a seam resonance system - a coal seam at the mountain massif.

摘要:... To understand the roles of these cells in controlling eye movements, we studied the optokinetic responses ( OKR s) of mutant mice with dysfunctional ON ‐bipolar cells that have a functional obstruction of transmission to ON direction‐selective ganglion cells. Experiments...

摘要:Abstract(#br)This study compares brain activation patterns evoked by smooth pursuit and by fixation suppression of the optokinetic reflex (OKR) using similar retinal stimulation. Functional magnetic resonance imaging (fMRI) was performed during smooth pursuit stimulation in which...

摘要:... The gain of the optokinetic reflex (OKR) progressively decreased from mean values of 0.78 ± 0.15 to 0.05 ± 0.06 in the 0.025 Hz–0.5 Hz frequency range. A close correlation was observed between the OKR slow phase velocity and the modulation of the neuronal responses in t...

摘要:Abstract(#br)Vestibulo-ocular reflex (VOR)-optokinetic reflex (OKR) interaction was studied in normal human subjects during active sine-like head movements in the horizontal plane for a variety of vestibular-optokinetic stimulus combinations (frequency range, 0.05–1.6 Hz). At...
