We have used electrical stimulation of the vestibular apparatus to reveal parallels between the physiological responses of the vestibular afferents activated at different currents and the properties of the evoked eye movements before and after magnifying spectacles had been used to cause motor learning in the vestibulo-ocular reflex (VOR). Stimulation with the lowest currents caused little or n...

Generation and features of the radio frequency (RF) hollow cathode discharge (HCD) are compared for the atmospheric and moderate pressures. The atmospheric-pressure plasma systems, fused hollow cathode (FHC) and hybrid hollow electrode-activated discharge (H-HEAD), are described. Examples of applications where both FHC and H-HEAD have already been employed are given, and potentials for new proc...

introduction: better use of water and soil resources in paddy fields, increase in rice production and farmer's income, installation of subsurface drainage system is necessary. the main goalof these systems, are aeration conditions improvement prevention of water logging, yield increase, land use increase and multiuse of the land. in different countries, installation of subsurface drainage cause...

This two-part paper describes a compressor redesign program for improving efficiency, lowering sound emission, and cost. Part 2 indicates how sound and discharge pulse were reduced through research conducted on transmission loss of plastic vs. steel manifolds and discharge pulse modeling using four pole parameters Common reciprocating compressors utilize steel flapper valves and a Cylinder Head...

OBJECTIVE Our study examined the prognostic factors involved in the outcome of patients with chronic subdural hematoma (CSDH) who had undergone burr hole drainage procedures, and investigated the association between outcome and traumatic head injury. In addition, we explored factors related to recurrence. METHODS This study enrolled 238 patients with CSDH who had undergone burr hole drainage....

One of the most important conflicts that shaft spillways have to deal with is vortex formation. This phenomenon leads to some unfavorable effects such as vibration in the body of structures, air entrainment and reduced overflow capacity of the spillway. Among all solutions for disrupted vortex formation, an innovative one called circular piano-key spillway, based upon piano key weir principles ...

ABSTRACT- Measurement of irrigation water in agricultural areas is necessary, especially, in arid and semi-arid regions. Long-throated flumes have been used to measure irrigation water and are known to be inexpensive devices with high performances. In these structures, head-discharge tables are predicted theoretically with no need to calibrate. In this study, the model of LOTF ...

Milled rice from a laboratory mill and a commercial–scale mill was evaluated for head rice yield using a shaker table and a machine–vision system called the GrainCheck. Comparisons were made for both medium– and long–grain rice varieties. For each variety, samples with different levels of broken kernels were analyzed to determine the performance of the two instruments over a range of head rice ...
