(n.) The part of a vacuum tube opposite the cathode. Upon it the cathode rays impinge.
Example Sentences:
Cathode
Definition:
(n.) The part of a voltaic battery by which the electric current leaves substances through which it passes, or the surface at which the electric current passes out of the electrolyte; the negative pole; -- opposed to anode.
Example Sentences:
(1) If this is what 70s stoners were laughing at, it feels like they’ve already become acquiescent, passive parts of media-relayed consumer society; precursors of the cathode-ray-frazzled pop-culture exegetists of Tarantino and Kevin Smith in the 90s.
(2) In a starch block, migration was toward the cathode at pH 8.0.
(3) A significant improvement in the precision of the hollow cathode as an emission source is reported.
(4) The parotid saliva of the caries-rampant group showed a significantly higher level of anodemigrating proteins, predominantly isoamylases, and a significantly lower level of cathode-migrating proteins than that of the caries-resistant group in both paraffin-stimulated and sour lemon-stimulated salivary flows.
(5) The variability in response is attributed to interaction between nearby, on-going synaptic bombardment and the stimulus, implying that surface cathodal stimuli directly activate corticospinal neurons at the spike trigger zone (presumably the initial segment).
(6) A pure Domal magnesium anode was utilized with this cathode, which seemed to be a good compromise between to battery's voltage, its lifetime, and its lack of toxicity to body tissues.
(7) When the new bone formation in the medullary canal surrounding an inactive cathode disappeared, it was replaced by a network of polymorphic cells.
(8) L-Glu induced F increase also in the receptors fully suppressed either by cathodal pulses or by high Mg (15 mM), which indicated the postsynaptic action.
(9) One fraction migrates towards the cathode: lysosyme (25 to 35%).
(10) By isoelectrofocusing in agarose, the properdin factor allotype BfF could be split into two subtypes: BfFa with one major cathodic band and BfFb with the same cathodic band but in addition a major anodic band.
(11) To determine if anodal excitation during bipolar stimulation facilitates the initiation of sustained monomorphic ventricular tachycardia, nonsustained polymorphic ventricular tachycardia, or repetitive ventricular responses, both bipolar and cathodal unipolar programmed ventricular stimulation with one to three extrastimuli delivered during ventricular pacing at two rates from the right ventricular apex were performed in 28 patients evaluated for spontaneous sustained ventricular tachycardia or ventricular fibrillation (11 patients), nonsustained tachycardia (eight patients), or syncope (nine patients).
(12) Four electrode configurations were tested: 1) distal electrode (cathode) to proximal electrode and chest wall patch (common anodes), 2) distal electrode (cathode) to chest wall patch (anode), 3) distal electrode (cathode) to proximal electrode (anode), and 4) chest wall patch (cathode) to proximal electrode (anode).
(13) Although all five proteins specifically bind to porcine thyroglobulin, the cathodal migrating proteins bind more strongly than the anodal migrating proteins.
(14) Two antigens migrated towards the anode, and the third migrated towards the cathode.
(15) In electrophoresis on cellulose acetate, TEB buffer, pH 8.5, mobilities are calculated as ratios of the mobility of simultaneously analyzed Hb C. In electrophoresis on citrate agar, pH 6.0, anodic mobilities are also related to Hb C, cathodic ones to Hb F. In globin electrophoresis in urea 2-mercaptoethanol buffers, pH 6.0 and 8.9, mobilities of the mutant globin chains are calculated in relation to the mobilities of normal alpha and beta chains.
(16) The protein S-100 was increased 3.4% and the neuronal protein 14-3-2 was increased 12.2% for the cathodal component whereas the anodal component was not increased.
(17) The continuous and direct registration of the vectorcardiogram was realized by cathode-ray oscillographic methods by F. Schellong in 1937 and hence introduced into clinical diagnostics.
(18) The content of the number of antigens (especially of cathode fractions) in trisomic cells was significantly low as compared with those in control diploid cells, whereas in triploid ones it differed slightly.
(19) The stimulus consisted of 2.5- to 4.0-mA cathodal pulses, each of 1-ms duration, beginning at a frequency of 10 Hz and increasing by 10-Hz increments to 100 Hz.
(20) RTG-2 and CHSE-214 cells with BSS and fish serum were attracted from the central chamber (to which each cell sample was added) to the cathode chambers, but no attraction was detected when these cells were used with phosphate-buffered saline.
