La travesía obsoleta: la indefensión del consumidor

La obsolescencia programada es el deseo de tener algo un poco más nuevo, un poco mejor, un poco más rápido de lo necesario. El texto estudia este fenómeno a la luz del Estatuto del Consumidor – Ley 1480 de 2011 para determinar si el consumidor colombiano está suficientemente protegido con él.

El seguro de crédito comercial como garantía de operaciones financieras

Inicialmente se había observado como una fianza de obligaciones financieras, en la cual una compañía de seguros asumía la responsabilidad subsidiaria por el pago de obligaciones monetarias adquiridas por un deudor frente a un acreedor

Créditos e insolvencia

Esta obra se encuentra estructurada en dos grandes partes. En la primera parte, el lector encontrará generalidades sobre los créditos y las maneras en que los mismos pueden hacerse valer al interior de un proceso concursal. Aspectos como la insinuación del crédito, su reconocimiento al interior de estos procesos y la impugnación, son trabajados de manera extensa, indicando en cada caso, de manera precisa, la regulación a aplicar para cada uno de estos momentos procesales al interior del concurso de acreedores. En la segunda parte, encontrarán un estudio detallado de los créditos privilegiados al interior del proceso concursal. Como podrá apreciarse, se trata de una obra comprensiva de todos los aspectos que una persona interesada en un proceso concursal, cualquiera sea su posición al interior del mismo (deudor, acreedor, etc.), debe tener en cuenta para resolver todas las dudas que le surjan, aspectos todos abordados con la mayor rigurosidad y profundidad.

Signatures of superconducting and pseudogap phases in ultrafast transient reflectivity of Ca(Fe0.927Co0.073)(2)As-2

We present femtosecond time-resolved pump-probe spectroscopic studies of a pseudogap (PG) along with the superconducting (SC) gap in an overdoped iron pnictide Ca(Fe0.927Co0.073)(2)As-2. It is seen that the temperature evolution of the photo-excited quasiparticle (QP) relaxation dynamics, coherently excited A(1g)-symmetric optical phonon and two acoustic phonon dynamics behave anomalously in the vicinity of the superconducting transition temperature T-c. A continuous change in the sign of the experimentally measured transient differential reflectivity Delta R/R signal at the zero time delay between the pump and probe pulses at a temperature of similar to 200K is inferred as an evidence of the emergence of the PG phase around that temperature. This behavior is independent of the pump photon energy and occurs for crystals without the spin density wave phase transition. Copyright (C) EPLA, 2014

Diário da Constituinte [gravação de vídeo] : [programa n. 073]

Na Comissão da Organização Eleitoral, Partidos e Garantias das Instituições da Assembleia Nacional Constituinte (ANC), todos os temas polêmicos serão discutidos duas vezes antes da votação final. São eles: o papel dos militares, criação de uma corte constitucional e a fixação dos tempos dos mandatos. Saulo Queiroz (PFL-MS) acredita que assim a participação será democrática. A Comissão de Sistema Tributário, Orçamento e Finanças quer acabar com a impunidade dos crimes de colarinho branco. O deputado Fernando Gasparian (PMDB-SP), relator da Comissão, propõe a punição rigorosa e o impedimento da União em assumir os prejuízos financeiros causados por eles. A Subcomissão dos Negros, Populações Indígenas, Pessoas Deficientes e Minorias reafirma e amplia o direito das minorias. José Carlos Sabóia (PMDB-MA) relata que caberá a Constituição e ao Tribunal Constitucional impedir qualquer prática de discriminação racial. Populares falam a respeito. Para os deficientes físicos, alguns direitos já estão garantidos no anteprojeto. Nelson Seixas (PDT-SP) afirma que agora as entidades responsáveis pelos interesses dos deficientes viverão um novo momento. Ione Pereira França, presidente da Associação dos Deficientes Físicos de Brasília, acredita que só através da implementação de leis haverá mudanças.

Effect of supplementation silage ("Festuca dolichophylla, Avena sativa and Vicia sativa") on weight gain and mortality in adult alpacas ("Vicugna pacos")

This study was conducted in order to evaluate the effect of supplementation with silage (Festuca dolichophylla, Avena sativa and Vicia sativa) on weight gain and mortality in adult alpacas, during the months of dry season (June to August) in Huancavelica region. 300 female alpacas 3 and 4 years of age (physiological state: pregnant) were used, which were assigned to the following treatments: SP, grazing only PSE15, grazing plus supplementation of 1.5 kg of silage. Alpacas were supplemented once daily. In each alpaca they were recorded live weight at the beginning and end of the experiment. The weight gain was -0.02 y 2.05 kg for SP and PSE15 respectively (p <0.001) treatments. Mortality was 5.3% and 2.7% for SP and PSE15 respectively (p=0.073) treatments. It can be concluded under the conditions of this trial silage supplementation has effect on weight gain and maybe also on mortality in alpacas.

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.
