1. Osciladores harmÃnicos acoplados dependentes do tempo. / Harmonic oscillators coupled time-dependent.
Neste trabalho apresentamos soluÃÃes clÃssicas e quÃnticas de osciladores harmÃnicos acoplados dependentes do tempo. Nesses sistemas as massas, frequÃncias e o parÃmetro de acoplamento sÃo funÃÃes do tempo. Quatro sistemas sÃo investigados. Para obter as soluÃÃes clÃssicas usamos uma transformaÃÃo de coordenada e momento juntamente com uma tr

2. The constituted relationships in the pedagogical work involving sheltered children: an analysis searching the sense of quality / Os relacionamentos constituídos no trabalho pedagógico da educação infantil envolvendo crianças abrigadas : análise em busca do sentido da qualidade
This work analyzed, in the perspective of the quality, the constituted relationships in the infantile educations pedagogical work involving sheltered children. We discussed this research as been realized in a infantile education institution located in a entity of assistance in Distrito Federal, having as emphasis the right of the children sheltered to an inf

3. Feijão-de-porco [Cnavalia ensiformis (L.) D.C.] cultivado com diferentes fontes de nitrogenio : fixação de N2, fotossintese e crescimento
Several reports point to a negative effect of mineral N on the fonnation and activity of root nodules in legumes that fix the N2 by simbiotic association with rizobia. However, there are few studies establishing a relation between aspects ofthe photosynthesis and the source of N. In this study, an investigation was carried out to verify the influence of the

4. Bacterial luciferase as a reporter of circadian gene expression in cyanobacteria.
To allow continuous monitoring of the circadian clock in cyanobacteria, we previously created a reporter strain (AMC149) of Synechococcus sp. strain PCC 7942 in which the promoter of the psbAI gene was fused to Vibrio harveyi luciferase structural genes (luxAB) and integrated into the chromosome. Northern (RNA) hybridization and immunoblot analyses were perf

5. Rapid oscillations in omental lipolysis are independent of changing insulin levels in vivo
Abnormal fat metabolism plays an important role in the pathogenesis of obesity-related type 2 diabetes mellitus. This study examined whether free fatty acid levels (FFAs), like insulin levels, oscillate rapidly in plasma. Peripheral and portal blood samples from dogs were assayed for FFA, glycerol, glucose, and insulin. FFA and glycerol showed correlated osc

6. The double par locus of virulence factor pB171: DNA segregation is correlated with oscillation of ParA
Prokaryotic plasmids and chromosomes encode partitioning (par) loci that segregate DNA to daughter cells before cell division. Recent database analyses showed that almost all known par loci encode an ATPase and a DNA-binding protein, and one or more cis-acting regions where the proteins act. All par-encoded ATPases belong to one of two protein superfam

7. Calcium entry-dependent oscillations of cytoplasmic calcium concentration in cultured endothelial cell monolayers.
Bovine endothelial cell monolayers grown to confluence and stimulated with bradykinin responded with periodic fluctuations in intracellular Ca2+ concentration ([Ca2+]i) when exposed to K(+)-free Hepes-buffered saline. The fluctuations in [Ca2+]i measured with fura-2 were synchronized among the population of cells observed and were sensitive to extracellular
