Electrical stimulation of the vestibular sensory system during virtual environment simulations reduces the incidence of simulator adaptation syndrome (SAS). However, interactions between vestibular stimulation and complex visual scenery can increase oculomotor symptoms. This study examined an alternative technique to reduce symptoms of SAS using the application of galvanic cutaneous stimulation...

In this paper, a new kind of carbon steel (CS) and stainless steel (SS) galvanic sensor system was developed for the study of rebar corrosion in different pore solution conditions. Through the special design of the CS and SS electronic coupons, the electronic resistance (ER) method and zero resistance ammeter (ZRA) technique were used simultaneously for the measurement of both the galvanic curr...

BACKGROUND Technological advances in wire selection and bracket design have led to improved treatment efficiency and allowed longer time intervals between appliance adjustments. The wires remain in the mouth for a longer duration and are subjected to electrochemical reactions, mechanical forces of mastication and generalized wear. These cause different types of corrosion. This study was done to...

An anti-galvanic replacement reaction (AGRR) of copper(II) ions reduced by ultra-small ssDNA-templated silver nanoclusters forming Ag-Cu alloy nanoparticles was observed. The reaction is against the classic galvanic theory and was monitored sensitively by the light-scattering technique.

Biocompatible materials used for the fabrication of dental crowns were studied. Patients were treated with Gold, Porcelain and Zirconia crowns. Dental crowns were selected according to patient’s clinical status and needs. We found that Gold crowns had low patient acceptance because of poor aesthetics and high cost. Gold crowns could not be used opposite to amalgam restorations for the fear of g...

tro-galvanic battery provides a perfect and instantaneous cure in ordinary cases ; that a record shewing a very large number of cases so treated is available, and that during the hot and wet months some of the medical subordinates request the privilege of taking home the galvanic batteries so as to be able to resort to this method of treatment without loss of time. I have the honor to be, Sir, ...

Stainless steels are susceptible to the localized pitting corrosion that leads to a huge loss to our society. Studies in the past decades confirmed that the pitting events generally originate from the local dissolution in MnS inclusions which are more or less ubiquitous in stainless steels. Although a recent study indicated that endogenous MnCr2O4 nano-octahedra within the MnS medium give rise ...

BACKGROUND Currently available methods for permanent removal of unwanted body hair are either slow or may result in painful side effects or scarring. OBJECTIVE The authors investigated the safety and effectiveness of galvanic current by patch and probe technique as a method of permanent hair removal. RESULTS Microscopic evidence confirmed that galvanic current treatment using either a probe...

In a recent paper in Frontiers Cohen et al. (2012) asked "What does galvanic vestibular stimulation actually activate?" and concluded that galvanic vestibular stimulation (GVS) causes predominantly otolithic behavioral responses. In this Perspective paper we show that such a conclusion does not follow from the evidence. The evidence from neurophysiology is very clear: galvanic stimulation activ...
