Fault isolation in overhead distribution networks: new developments in outdoor fault detectors

In recent years, the importance of power quality is rapidly growing. As a consequence, distributors are called to guarantee a reduced number and duration of supply interruptions by adopting new strategies in order to identify and isolate faults along distribution feeders. In the paper some recent results obtained in the development of outdoor fault detectors for overhead lines are reported. Furthermore many possible applications of the innovative current and voltage sensors to future active distribution networks with distributed generation have been identified

Persistence of elevated aminotransferases in Wilson's despite adeguate therapy.

Wilson's disease (WD) is characterized by a dramatic build-up of intracellular hepatic copper with subsequent hepatic and neurological abnormalities.1, 2 Prompt recognition of WD is crucial, because if not treated, the disease is fatal.2, 3 Most childhood cases of WD present with liver disease that mimics various liver disorders, while the typical neurological signs are usually absent. Hypertransaminasemia may be the only altered laboratory sign in early WD. Histological evidence of severe liver disease may occur in children with isolated hypertransaminasemia.4, 5 The response of serum transaminase levels to penicillamine and zinc treatment in WD is poorly understood, because the children with WD in earlier studies had a relatively advanced disease, and treatment efficacy was evaluated from parameters (i.e., jaundice, ascites, and neurological symptoms) other than serum transaminases.6–
