Ley de contratación administrativa : reforma a la contratación estatal

La obra constituye una guía explicativa de las principales modificaciones contenidas en la Ley 1150 de 2007, mediante la cual se modifica el régimen de contratación pública en Colombia. En este libro se realiza un análisis del proceso legislativo surtido por esta reforma, la cual logró materializarse después de serios intentos de modificación de las normas que rigen los contratos que celebra el Estado.

Proyección y cambios recientes en el arbitraje de contratos públicos en Francia. Estudio comparativo sobre su evolución en Francia y en Colombia

El arbitraje en Francia y en Colombia parte de una misma lógica: la autonomía de la voluntad y la libre disposición de los derechos como criterios indispensables para la arbitrariedad de los litigios. A pesar de esto, la prohibición del arbitraje a las personas de derecho público francés es el resultado de una especificidad típicamente francesa: la separación de los órdenes de jurisdicción. En Francia no existen sino dos jurisdicciones, la judicial (Jurisdicción ordinaria) y la administrativa. La autonomía de esta última fue el fruto de una lenta evolución ganada gracias al trabajo del Consejo de Estado francés. En consecuencia, la prohibición orgánica del arbitraje fue arduamente defendida por éste en múltiples ocasiones. Sin embargo, en la actualidad, su posición ha dado un importante giro que se manifiesta claramente en el informe que se traduce en el presente texto.

Diário da Constituinte [gravação de vídeo] : [programa n. 023]

A Comissão do Sistema Tributário, Orçamento e Finanças da Assembleia Nacional Constituinte (ANC) possui a missão de redigir uma legislação tributária mais distributiva, que atenda os interesses dos diversos grupos da sociedade. A Comissão divide-se em: Subcomissão de Tributos, Participação e Distribuição da Receitas; Subcomissão de Orçamentos e Fiscalização Financeira e Subcomissão do Sistema Financeiro. O atual panorama de arrecadação de impostos, com a União recolhendo 62% dos impostos e a retenção de 47%, os constituintes dizem ser insustentável e propõem uma redistribuição. Em entrevista, o Deputado Ivo Vanderlei (PMDB-SC) propõe a descentralização dos tributos e competências. O Deputado José Serra (PMDB-SP) fala sobre a extinção, fusão ou criação de novos impostos que não sobrecarreguem as classes mais populares e comenta sobre a arrecadação do imposto de renda. O professor de economia da UnB, Décio Munhoz, apoia profundas mudanças no imposto de renda. Em entrevista, os Deputados Ivo Vanderlei (PMDB-SC) e Francisco Dornelles (PFL-RJ) defendem maior participação do Legislativo na elaboração do orçamento da União.

CS 30322--023: An Ultra Metal-Poor TP-AGB Star?

A search for star formation around the Galactic halo B-type star PHL 346 with the 2dF spectrograph

A preliminary search for stars that may have formed coevally with the apparently young halo B-type star PHL 346 has been performed with the 2dF multifibre spectrograph on the Anglo- Australian Telescope (AAT). Candidates were selected for spectroscopy from APM scans of B and R Schmidt plates centred on PHL 346. A total of 476 stars of spectral type A or F were found; radial velocity estimates and more accurate spectral type assignments narrowed the number of possible coeval candidates to 6 A-type and 14 F-type stars. A statistical analysis of these results using a comparison with a control field suggests that the number of A-type or F-type candidate stars around PHL 346 is not unexpected, and that they need not be associated with PHL 346. A number of ways to improve the project are suggested.

SGK1 activity in Na+ absorbing airway epithelial cells monitored by assaying NDRG1-Thr(346/356/366) phosphorylation

Studies of HeLa cells and serum- and glucocorticoid-regulated kinase 1 (SGK1) knockout mice identified threonine residues in the n-myc downstream-regulated gene 1 protein (NDRG1-Thr(346/356/366)) that are phosphorylated by SGK1 but not by related kinases (Murray et al., Biochem J 385:1-12, 2005). We have, therefore, monitored the phosphorylation of NDRG1-Thr(346/356/366) in order to explore the changes in SGK1 activity associated with the induction and regulation of the glucocorticoid-dependent Na+ conductance (G (Na)) in human airway epithelial cells. Transient expression of active (SGK1-S422D) and inactive (SGK1-K127A) SGK1 mutants confirmed that activating SGK1 stimulates NDRG1-Thr(346/356/366) phosphorylation. Although G (Na) is negligible in hormone-deprived cells, these cells displayed basal SGK1 activity that was sensitive to LY294002, an inhibitor of 3-phosphatidylinositol phosphate kinase (PI3K). Dexamethasone (0.2 mu M) acutely activated SGK1 and the peak of this response (2-3 h) coincided with the induction of G (Na), and both responses were PI3K-dependent. While these data suggest that SGK1 might mediate the rise in G (Na), transient expression of the inactive SGK1-K127A mutant did not affect the hormonal induction of G (Na) but did suppress the activation of SGK1. Dexamethasone-treated cells grown on permeable supports formed confluent epithelial sheets that generated short circuit current due to electrogenic Na+ absorption. Forskolin and insulin both stimulated this current and the response to insulin, but not forskolin, was LY294002-sensitive and associated with the activation of SGK1. While these data suggest that SGK1 is involved in the control of G (Na), its role may be minor, which could explain why sgk1 knockout has different effects upon different tissues.

The VLT-FLAMES survey of massive stars: observations centered on the Magellanic Cloud clusters NGC 330, NGC 346, NGC 2004, and the N11 region

We present new observations of 470 stars using the Fibre Large Array Multi-Element Spectrograph ( FLAMES) instrument in fields centered on the clusters NGC330 and NGC346 in the Small Magellanic Cloud (SMC), and NGC2004 and the N11 region in the Large Magellanic Cloud (LMC). A further 14 stars were observed in the N11 and NGC330 fields using the Ultraviolet and Visual Echelle Spectrograph (UVES) for a separate programme. Spectral classifications and stellar radial velocities are given for each target, with careful attention to checks for binarity. In particular, we have investigated previously unexplored regions around the central LH9/LH10 complex of N11, finding similar to 25 new O-type stars from our spectroscopy. We have observed a relatively large number of Be-type stars that display permitted Fe II emission lines. These are primarily not in the cluster cores and appear to be associated with classical Be-type stars, rather than pre main-sequence objects. The presence of the Fe II emission, as compared to the equivalent width of Ha, is not obviously dependent on metallicity. We have also explored the relative fraction of Be- to normal B-type stars in the field-regions near to NGC330 and NGC2004, finding no strong evidence of a trend with metallicity when compared to Galactic results. A consequence of service observations is that we have reasonable time-sampling in three of our FLAMES fields. We find lower limits to the binary fraction of O- and early B-type stars of 23 to 36%. One of our targets (NGC346-013) is especially interesting with a massive, apparently hotter, less luminous secondary component.
