Deployment of quality-of-service (QoS) based value-added services in IP networks necessitates the use of traffic engineering. Traffic engineering allows service providers to use the network resources efficiently, according to the different quality levels associated with the range of services they offer. Traffic engineering relies typically on monitoring(More)
Ultrastructural cytochemistry was used to localize a previously undescribed retinal enzyme activity, ie, "manganese-dependent pyrimidine 5'-nucleotidase" (MDPNase) activity in retinas from rats raised in cyclic light and killed at various times in the lighting cycle. In retinas fixed during the last 3 hr of darkness, at the beginning of the shedding period,(More)
The morphogenesis of the outer dense fibers (ODF) in rat spermatids has been studied by electron microscopy, and the synthesis and incorporation of proteins into the ODF during this process have been followed by radioautography using 3H-proline and 3H-cystine as precursors for ODF proteins. In the first phase (step 8-14), nine very fine fibers termed(More)
Indirect immunofluorescence and antibodies to tubulin were used to visualize the distribution of microtubules (MT) in short-term primary cultures of retinal pigment epithelial (RPE) cells isolated from the eyes of control RCS rats and those with inherited retinal degeneration. At all stages of cell spreading in vitro, the pigment granules (PG) in these(More)
