The speed of optical transmission links is growing at a rate which is difficult for the micro-electronic technology of ATM switches to follow. In order to cover the transmission rate gap between optical transmission links and ATM switches, ATM switches operating at multi Gbit/s rate have to be developed. A 10 Gbit/s/port shared memory ATM switch is under(More)
Isolated superfused field stimulated biopsy specimens of human peripheral arteries and veins, preincubated with 3H-( - )-NOradrenaline (NA) to label the neural stores of NA, were used to study the potency of dopamine (DA) and of NA as triggers of alpha-adrenoceptor mediated negative feedback control of sympathetic neurotransmitter secretion, evoked by(More)
To study the ultrastructural characteristics of the sympathetic nerve terminals of human omental veins, and of their relationship to the innervated smooth muscle cells, biopsy specimens were taken during abdominal surgery, rapidly fixed in glutaraldehyde/osmium and stained with uranylacetate. The results indicate that the veins have an extensive(More)
