Marginal productivity index policies for scheduling a multiclass delay-/loss-sensitive queue [PDF]

open access: yes, 2005
We address the problem of scheduling a multiclass M/M/1 queue with a finite dedicated buffer for each class. Some classes are delay-sensitive, modeling real-time traffic (e.g.

Oxygen tension-independent protection against hypoxic cell killing in rat liver by low sodium

open access: yesEuropean Journal of Histochemistry, 2017
The role of Na+ in hypoxic injury was evaluated by a time-course analysis of damage in isolated livers perfused with N2-saturated buffer containing standard (143 mM) or low (25 mM) Na+ levels. Trypan blue uptake was used to detect non-viable cells. Under

Characterization of the multiple-chamber perifused fat cell system.

open access: yesJournal of Lipid Research, 1979
A multiple-chamber perifused fat cell system is described. Six chambers containing fat cells were perifused in parallel with buffer. Perifusate was collected for assay of glycerol as an index of lipolytic rates and cells in each chamber can be taken for ...
