  • Light and Light Sources
    On the other hand, the electrodes may cause an early end of life of the lamp, if they get too hot, or the melting of an electrode tip might change the electrode shape and thus alter the operating conditions of the lamp.
  • Textbook of Stereotactic and Functional Neurosurgery
    … its coordinates or the angles and distance to the target point; plan up to five electrode tracks; display trajectories in two orthogonal views; simulate electrode insertion with a label and PFA-STN probability readout at the electrode tip as well as provide …
  • Review of resistance spot welding of steel sheets Part 2 Factors influencing electrode life
    Electrode deterioration causes growth of the electrode tip diameter, which has been shown to be dominant in determining the deterioration in weld quality in production operations.
  • Scanning Probe Microscopy
    Intrinsic electrode tips can suffer from wear effects that cause changes in electrode geometry and current response, as well as a loss of topographical resolution.
  • Impulse Breakdown of Liquids
    Repeated discharges on the barrier are displaced from the hemi- spherical electrode tip (r0 = 3.25 mm) approximately by 1.5 mm (Fig. 4.42).
  • Plant Electrophysiology
    … 6 Ag/AgCl coated Ag wire, 7 ion-selective barrel with sensor plug in the tip, 8 cell membrane potential barrel filled with 0.1 M KCl, 9 nutrient solution bathing plant, 10 plant tissue with micro electrode tip in a cell (cytoplasm …
  • Tumor Ablation
    With internal elec- trode tip cooling (of 15 ± 2°C using O°C saline perfusate), RF energy deposited into tissue and resultant coagulation necrosis were signifi- cantly greater (p < .001) than that achieved without electrode cooling.
  • Electrode pitting in resistance spot welding of aluminum alloy 5182
    The results indicated that electrode degradation, which eventually leads to weld failure, proceeded in four basic steps: aluminum pickup, electrode alloying with aluminum, electrode tip face pitting, and cavitation.
  • Patch-Clamp Analysis
    Finally to promote gigohm seals and to reduce the possibility of tip penetration into the cell during seal formation, electrode tips should be firepolished.
  • Current stepping programmes for maximising electrode campaign life when spot welding coated steels
    The most significant improvements in welding performance were obtained when the current was increased as a function of electrode tip growth.
