13. A-teams para um problema de transporte de derivados de petroleo
The present master s dissertation deals with the Prablem of Gil Transportation through Pipelines (PTDP) from the Brazilian Gil Company (Petrobrás). The company has a set of refineries and terminals all over the State of São Paulo, responsible for production and delivery of oil-derived products to consumers markets. The bases (terminals and refineries) don

14. Kinetics of desynchronization and distribution of generation times in synchronized cell populations.
The kinetics of the distribution of generation times in synchronized cells can be analyzed by using Fourier transform analysis. Deviations of the experimental data from the curve of completely asynchronous growth reflect the degree of synchrony at a particular time. Fourier transform analysis of these deviations yields the average generation time as well as

15. Regulation of Hemoglobin Synthesis in a Murine Erythroblastic Leukemic Cell: The Requirement for Replication to Induce Hemoglobin Synthesis
The induction of hemoglobin synthesis by dimethylsulfoxide in cells infected with Friend leukemia virus has been shown to depend on the number of cell divisions after the addition of the inducing agent. In asynchronous cultures the cells have a generation time of 24 hr, and hemoglobin synthesis occurs after 48 hr in the presence of dimethylsulfoxide. Generat

16. Effect of Nalidixic Acid on DNA Replication by Toluene-Treated Escherichia coli
Nalidixic acid inhibits DNA synthesis in toluene-treated E. coli, strain B/r, as it is well known to do in vivo. Both semiconservative and repair syntheses are affected, though to different degrees. Density-transfer experiments indicate that chromosomal replication is reinitiated when nalidixic acid is removed from toluene-treated cells after exposure to the

17. "Division potential" in Escherichia coli.
The phenotype of a minC mutant has been reexamined and found to correspond closely to the quantitative predictions of Teather et al. (R. M. Teather, J. F. Collins, and W. D. Donachie, J. Bacteriol. 118:407-413, 1974). We confirm that the number of septa formed per generation per cell length is fixed and independent of the number of available division sites a

18. Paramyosin phosphorylation site disruption affects indirect flight muscle stiffness and power generation in Drosophila melanogaster
The phosphoprotein paramyosin is a major structural component of invertebrate muscle thick filaments. To investigate the importance of paramyosin phosphorylation, we produced transgenic Drosophila melanogaster in which one, three, or four phosphorylatable serine residues in the N-terminal nonhelical domain were replaced by alanines. Depending on the residues

19. Random, Asynchronous, and Asymmetric Transcriptional Activity of Enhancer-Flanking Major Immediate-Early Genes ie1/3 and ie2 during Murine Cytomegalovirus Latency in the Lungs
The lungs are a major organ site of cytomegalovirus (CMV) pathogenesis, latency, and recurrence. Previous work on murine CMV latency has documented a high load and an even distribution of viral genomes in the lungs after the resolution of productive infection. Initiation of the productive cycle requires expression of the ie1/3 transcription unit, which is dr
