    Notizen: Abstract The electrical properties and preferred lattice site of Cu in GaAs were investigated combining electrical and optical measurements with ion beam and structural analysis. From this comprehensive study it was determined that Cu introduces two levels in the band gap, that the concentration of electrically active centers introduced by Cu diffusion is considerably smaller than the total Cu concentration, that this ratio of electrically active to total Cu concentration depends strongly on the cooling speed after diffusion, and that the portion of Cu that remains electrically inactive forms Cu-Ga precipitates.

    Notizen: Abstract In a retrospective study, 50 patients withobvious necrotizing pancreatitis (NP) were allocated infour groups according to the morphological aspects ofthe necrosis. Appearance of ascite (N1), extrapancreatic spread of necrosis towards neighboring organs(N2), a large amount of necrosis (N3), and infectednecrosis (N4), appears to be an easy and usefulguideline for the management of NP patients. Organfailures (72%) and mortality rate (36%) are higher whenthe process is infected. In the other groups, organicdysfunctions were frequent, but all the patients exceptone survived. The majority (80%) of patients were operated on. Only 20% of patients hadsuccessful nonsurgical treatment and they were in N3group. This percentage may increase through amorphological approach to treating necrosis, with theuse of endoscopic treatment for the disruption ofpancreatic duct, and better accuracy in the managementof patients with noninfected necrosis, whenever organfailures are present.
