Developments in electrical power transmission systems require the use of circuit-breakers with increasing breaking capacity. To test these equipments, direct testing is no longer feasible. This means that synthetic tests are necessary. These tests require circuits with a response specified by ANSI, IEC, ..., standards. Specific software has been created to(More)
The biological diagnosis of alcoholism is conducted routinely by assay of gamma-glutamyltranspeptidase (GGT) and mean corpuscular volume (MCV). However, their low specificity and sensitivity have prompted research to find other more reliable parameters. Stibler showed an increase in desialylated transferrin [carbohydrate-deficient transferrin (CDT)] in(More)
In an open, clinical trial comprising a total of 49 depressed in-patients, a new selective 5-HT uptake inhibitor citalopram was administered by intravenous infusion in doses of 20-60 mg once daily for per 3 weeks. The therapeutic effect was assessed globally and by means of the CPRS subscale for depression (MADRS). About 40 per cent of the patients showed a(More)
We describe a single-crystal emitter fabrication process compatible with self­ aligned bipolar transistor architectures. Combined with an epitaxial SiGe base, the single-crystal emitter is shown to provide the high speed and low l/f noise features required for RF and microwave circuit applications.
