The following problem is proved to be NP-complete: given n tasks, such that each task has processing time \tau=2, and has no more than k=3 possible starting times, does there exist a feasible schedule for these tasks on a single processor? This result establishes a sharp borderline between NP-complete and polynomially solvable versions of this problem with respect to the parameters \tau and k. [less ▲]

The levels of the water-soluble reductants ascorbic acid and glutathione and the activities of the enzymatic antioxidants superoxide dismutase, catalase, ascorbate peroxidase, monodehydroascorbate and ... [more ▼]

The levels of the water-soluble reductants ascorbic acid and glutathione and the activities of the enzymatic antioxidants superoxide dismutase, catalase, ascorbate peroxidase, monodehydroascorbate and dehydroascorbate reductases and glutathione reductase were determined in a fully habituated nonorganogenic sugarbeet callus line (considered a neoplasm) compared with a normal hormone-dependent callus of the same plant. Ascorbic acid was not recovered from either of the two calluses, irrespective of the technique used. Glutathione was titrated at a slightly higher level in the normal callus. Catalase activity was almost nonexistent in the habituated callus. The other enzymes (superoxide dismutase, glutathione reductase, monodehydroascorbate reductase, dehydroascorbate reductase, and ascorbate peroxidase) were found to have higher activities in the habituated callus. The results are interpreted as a higher protection of the neoplastic habituated cells against oxygen-free radicals and hydroperoxide-dependent oxidations. Such strong scavenging properties of the habituated cell line could explain previous results already reported, namely the stimulation of cell division at the expense of cell differentiation. © 1992 Tissue Culture Association.
