Serotonin‐Induced Short‐Circuit Current in Pig Jejunum
Journal of Veterinary Medicine Series A, 1994SummaryThis paper presents the effects of serotonin (5‐HT) on short‐circuit current (SCC), sodium and chloride fluxes, and prostaglandin E2release in pig jejunum, using the Ussing‐chamber technique.5‐HT elicited a dose‐dependent increase in SCC, yielding an EC50of 6 ± 4 μM and EMAXof 77± 8 μA. cm−2using about 100 ±.

Limitation of short-circuit currents
2005The expansion of electrical power systems by new power stations and new lines (overhead transmission lines and cable circuits) results in an increase of short-circuit currents due to an increase in sources feeding the short-circuit and due to a reduction of system impedance. The improvement of existing installations and the replacement of equipment are

Short-circuit current of induction motors and generators
Journal of the American Institute of Electrical Engineers, 1921There has been a rather prevailing opinion that a sudden short circuit of an induction generator would not cause a serious initial rise in current such as occurs in synchronous generators. This has led to the proposal of the use of such machines as a partial solution of the short-circuit problem on a-c. systems.

Short circuit current in tight and leaky epithelia
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1978The effect of short circuit current on the unidirectional fluxes of ions transported across tight and leaky epithelia was investigated. It was found that short circuiting of the frog gastric mucosa (classified as a tight epithelium) caused a decease of the passive JClms and a significant increase of the net Cl- secretion. However, no significant change

Short circuit current in rat adrenal capsule/glomerulosa
Endocrine Research, 1998Angiotensin II (AII) and potassium are the primary regulators of aldosterone secretion by adrenal zona glomerulosa cells. Electrophysiological studies using isolated adrenal tissues and dispersed zona glomerulosa cells show that stimulation by these secretagogues results in depolarisation of the plasma membrane and the opening of voltage-sensitive ion ...

"Characteristic" Currents and Countercurrents. For short-Circuits Diagnosis
2020 IEEE Industry Applications Society Annual Meeting, 2020Many sophisticated software are available to analyse the design of electrical power systems. Therefore, it becomes relevant to know rules of the thumb to be able to diagnose in an elementary and intuitive way the computerized results.For the short circuit analysis, in most practical cases, it is sufficient to adopt simplified and standard based ...

Short-circuit current limitation by superconducting transformer
2016 13th Selected Issues of Electrical Engineering and Electronics (WZEE), 2016Limitation of thermal and dynamic effects of the passage of a short-circuit current can be obtained by limiting the short-circuit time and the value of the maximum initial short-circuit current — surge current. The paper presents the current state of research on superconducting transformers for the electrical power system, used for limiting the short ...

Short-circuit current ratings of equipment
49th IEEE/IAS Industrial & Commercial Power Systems Technical Conference, 2013The interrupting rating and short-circuit current rating of equipment is an key consideration for the installation of equipment in electrical distribution systems. To emphasize this consideration, the 2005 National Electrical Code (NEC®) added short-circuit current rating marking requirements for various types of equipment, that previously was not ...
