40 Gbit/s signals are simultaneously all-optically demultiplexed and wavelength converted into four 10 Gbit/s channels of individual wavelengths with a penalty below 1.5 dB,using only one monolithically integrated Mach-Zehnder interferometer with semiconductor optical amplifiers.
Scanning electron microscopy (SEM) was used to study an IUD from an asymptomatic patient with Actinomyces-like organisms on Papanicolaou smear and in whom Actinomyces israelii was determined to be present in cervical smears. The objective was to determine if there were any variations in surface morphology that might be correlated with the Actinomyces-like… (More)
The Authors study the lipidemic effects of a "middle-term" treatment with heparin calcium in vasculopathic subjects undergoing the drug for antithrombotic purposes. The series consists of 35 subjects (21 m, 14 f, mean age 57 +/- 8) suffering from peripheral arteriopathy (24 cases) and instable angina (11 cases) of arteriosclerotic nature, and free from… (More)
