background and aim: tinnitus is an auditory phantom percept in the absence of any objective physical sound source. although advances have been made in its treatment, there is very low percent of patients that report an elimination of their tinnitus. a novel approach using noninv­asive neuromodulation has emerged as an inter­esting and promising modality for tinnitus relief. our aim in this revi...

in this paper, we have studied the electrical properties of the randomly distributed metallic (co and fe) nano/ micro wires on silicon substrate. deposition was carried out potentiostatically into the pores of the track-etch polycarbonate membrane spin coated onto the si substrate. spin coated films were irradiated with 150mev ni (+11) ions at a fluence of 8e7 ions/cm2, followed by uv irradiati...

Imaging of electrical current by measuring the magnetic field which it produces requires the solution of the magnetic inverse problem. For a current restricted to a plane, the inverse problem can theoretically be solved by a linear spatial filtering method. We have demonstrated experimentally that currents restricted to the surface of a printed circuit board can be imaged using this method. To ...

density or gravity currents have been always one of the main causes for sedimentation along many of the dam reservoirs. so controlling this phenomenon is very important for increasing useful life of such reservoirs. in this research study the effect of a combination of rough bed and obstacle on the control of sedimentary density current has been investigated. experiments were conducted in a til...

The inverse approach from MR images to electrical propagation is very novel, but difficult due to complicated processes from electrical excitation to heart contraction. A novel strategy is presented to recover cardiac electrical excitation pattern from medical image sequences and ECG data. We used MRI images to estimate the current density and visualize it on the surface of the heart model. The...

medical staples are one of the nitinol shape memory alloys applications which their pedicles have to be bent for suitable function with an appropriate angle at a specified temperature .it is achievable by shape memory effect. for this purpose, samples of nitinol super elastic alloys were bent in a steel mold with different angles & formed orthopedic staples. then shape memory effect was ind...

this study investigates the vertical replacement of salts, variability of electrical conductivity (ec) and soil acidity (ph) due to direct electrical current. a plexiglas cylinder 100 cm in depth with a 14 cm radius was used as a soil container and filled with uniform moist soil to 90 cm. during the experiments, the bottom 10 cm of soil in the cylinder was kept saturated. a steel bar was used a...

The origin of electrical burns under gel-type surface electrodes is a controversial topic that is not well understood. To investigate the phenomenon, we have developed an excised porcine skin+gel model. In the present paper, we describe methods to detect these burns in the skin+gel model in an effort to understand the genesis of these burns. Burns were induced by severe electrical stimulation a...
