On the number of lines in the limit set for discrete subgroups of PSL(3,C)PSL(3,\Bbb{C})

Given a discret subgroup \Gamma\subset PSL(3,\C), we determine the number of complex lines and complex lines in general position lying in the complement of: maximal regions on which $\Gamma$ acts properly discontinuously, the Kularni's limit set of $\Gamma$ and the equicontinuity set of $\Gamma$. We also provide sufficient conditions to ensure that the equicontinuity region agrees with the Kulkarni's discontinuity region and is the largest set where the group acts properly discontinuously and we provide a description of he respective limit set in terms of the elements of the group

Bladder Mucosal CO2 Compared with Gastric Mucosal CO2 as a Marker for Low Perfusion States in Septic Shock

Recent reports indicate the possible role of bladder CO2 as a marker of low perfusion states. To test this hypothesis, shock was induced in six beagle dogs with 1 mg/kg of E. coli lipopolysaccharide, gastric CO2 (CO2-G) was measured with a continuous monitor, and a pulmonary catheter was inserted in the bladder to measure CO2 (CO2-B). Levels of CO2-B were found to be lower than those of CO2-G, with a mean difference of 36.8 mmHg (P < 0.001), and correlation between both measurements was poor (r2 = 0.16). Even when the correlation between CO2-G and ΔCO2-G was narrow (r2 = 0.86), this was not the case for the relationship between CO2-B and ΔCO2-B (r2 = 0.29). Finally, the correlation between CO2-G and base deficit was good (r2 = 0.45), which was not the case with the CO2-B correlation (r2 = 0.03). In our experience, bladder CO2 does not correlate to hemodynamic parameters and does not substitute gastric CO2 for detection of low perfusion states

Manual de inventarios para pymes basado en modelo de revisión continua.

El presente trabajo de grado propone el desarrollo de una herramienta para la toma de decisión en la gestión de inventarios; aplicable a las pymes especialmente dedicadas a la comercialización de materias primas, busca brindar las pautas básicas del modelo de gestión de inventarios de revisión continua, a aquellas empresas que realizan una gestión de inventarios empírica y sin ninguna herramienta informática.Especialista en Gerencia LogísticaEspecializació
