The electrokinetic phenomena is also used for decontamination and enhancement of soil–chemical interaction, apart from electro-osmotic consolidation of dewatering. In this paper, an attempt is made to decontaminate the Na contaminated clay using electro-kinetic principle for varying voltage, spacing and number of electrodes. Box type electrokinetic cell was used for this purpose. Results indica...

Permanent pervenous atrial synchronized ventricular pacing was successfully accomplished in three patients. Atrial sensing was obtained from an electrode positioned in the coronary vein. Atrial electrograms with P waves greater than 1.5 mv were present in all three cases. Ventricular stimulation was accomplished through a separate electrode placed in the right ventricular apex. The left cephali...

abstract wenner direct contact method is a method of estimating apparent electrical conductivity (eca) of agricultural soils in situ. this method can be affected by factors such as quality of electrodes in contact with soil, type of employed electric current, moisture content, clay content and compaction of soil. in this research, the effect of electrode type (rod and plate) and electric curren...

objective: the current study was undertaken to examine the bactericide effects of atmospheric plasma produced by flat and comb electrodes on e.coli. materials and methods: dc (20 w) and ac (500 w) power supplies, flat and comb electrodes, insulator and oxygen gas were used to produce atmospheric plasma. bactericide effects of the atmospheric plasma were studied on e.coli on sterilized plate pla...

A general approach for enhancing the selectivity of anion-responsive liquid-membrane electrodes is described. The method is based on use of the receptor channel of a flowthrough dialyzer unit as the injection loop in a flow-injection system. An appropriate membrane in the dialyzer prevents ionic interferents from reaching an inselective electrode in the final flow stream The concept is demonstr...

In the visual cortex of rabbits and a marmoset monkey, 32 and 64 microwires, respectively, were chronically implanted by an indirect insertion method so that the cortex was penetrated from the white matter. For more than 1 year recordings of action potentials of good quality were obtained at most electrodes. Recording stability was judged by spike shape, spike train autocorrelograms, and spike ...

In-situ three terminal electron field emission characterisation of an isolated multiwalled carbon nanotube has been performed. Both anode and gate electrodes are attached to high precision piezo-drivers allowing for the characterisation of single emitters. All measurements are performed in a scanning electron microscope allowing accurate knowledge of the local environment of the nanotube to be ...

In order to extract neural information, action potentials recorded with cuff electrodes from peripheral nerves were classified into unit activities. The classification was performed based on their waveforms, as it was considered that they were affected by the radius of nerve fiber and the distance between fiber and recording electrode. This study focused on automatic classification method. Acti...

The analysis of network interactions among dynamical units and the impact of the coupling on self-organized structures is a challenging task with implications in many biological and engineered systems. We explore the coupling topology that arises through the potential drops in a flow channel in a lab-on-chip device that accommodates chemical reactions on electrode arrays. The networks are revea...

Introduction: Different Perimodiolar electrodes were developed by many cochlear implant (CI) manufacturers in the past few years. Possible advantages are lower stimulation thresholds and a better channel separation. A position close to the modiolus can be facilitated by different means: preformed electrode shape (Nucleus ContourTM electrode, Cochlear Corp., Australia), additional positioning el...
