On the generalized Feng-Rao numbers of numerical semigroups generated by intervals

We give some general results concerning the computation of the generalized Feng-Rao numbers of numerical semigroups. In the case of a numerical semigroup generated by an interval, a formula for the $r^{th}$ Feng-Rao number is obtained.Comment: 23 pages, 6 figure

The second Feng-Rao number for codes coming from telescopic semigroups

In this manuscript we show that the second Feng-Rao number of any telescopic numerical semigroup agrees with the multiplicity of the semigroup. To achieve this result we first study the behavior of Ap\'ery sets under gluings of numerical semigroups. These results provide a bound for the second Hamming weight of one-point Algebraic Geometry codes, which improves upon other estimates such as the Griesmer Order Bound

A randomised study on the clinical progress of high-risk elective major gastrointestinal surgery patients treated with olive oil-based parenteral nutrition with or without a fish oil supplement

n-3 Fatty acids have clinical benefits. The primary aim of the present study was the assessment of infection in patients who underwent major high-risk elective gastrointestinal surgery receiving postoperatively fish oil (FO)-supplemented parenteral nutrition (PN), compared with those receiving a standard olive oil (OO) emulsion. The secondary aims were the assessment of anti-inflammatory response and evaluation of tolerance and safety of these emulsions. A prospective, randomised, double-blind study was performed in patients requiring at least 5 d of PN. An isoenergetic and isoproteic formula was administered: group A received OO alone, while group B received OO that was partially replaced with FO (16.6 %, w/w). End points were outcome measures (mortality, sepsis, infection, hospitalisation days and PN duration), inflammatory response (C-reactive protein (CRP), prealbumin and leucocytes) and safety (TAG and glucose metabolism, and liver and kidney function). Statistical analysis was done using Student's t test and Fisher's exact test (P < 0.05). Twenty-seven patients were evaluated, with thirteen patients receiving FO. In this group, a significantly lower incidence of infections was found (23.1 v. 78.6 %, P = 0.007). CRP, prealbumin and leucocytes were not significantly different between the groups. There were no differences in safety parameters. We conclude that high-risk surgical patients receiving FO-supplemented PN for 5 d present a lower incidence of infection. Emulsions were safe and well tolerated

Tratamiento quirúrgico de la patologia urgente del colon izquierdo

El objetivo de este estudio es evaluar la morbilidad y mortalidad postoperatoria tras la aplicación de un protocolo terapéutico en los pacientes intervenidos de urgencia por patología del colon izquierdo. Como primera opción se practicó el Lavado Anterogrado Peroperatorio en todas las lesiones del colon izquierdo que precisaron intervención urgente. En lesiones irresecables, peritonitis fecaloidea, deterioro del estado general o lesiones asociadas en el resto del colon. se aplicaron otras opciones: la colostomía de descarga, la operación de Hartmann o la colectomía subtotal. Se practicaron 127 resecciones urgentes del colon izquierdo. En 56 casos se optó por la operación de Hartmann. en 38 por la colectomía subtotal y en 33 por el lAP. La complicación más frecuente fue la sepsis abdominal (29%). La mortalidad operatoria global fue del 24%. 390Ai para la operación de Hartmann. 16% para la colectomía subtotal y 6% para el LAP. El LAP es la intervención de elección en aquellos pacientes con buen estado general que presentan patología urgente del colon izquierdo sin peritonitis fecaloidea. ni lesión irreversible del colon derecho

Submarine canyons and related features in the Alboran Sea: continental margins and major isolated reliefs

The analysis of a data set of multibeam bathymetry plus high resolution seismic and parametric profiles allow us to characterize the geomorphologic units on the Alboran Sea-floor as well as the evolution of morpho-sedimentary systems along the Pliocene and Quaternary, later than the main erosive Messinian event. Since the opening of the Gibraltar Straits, the sedimentary evolution of this basin has been controlled by the interchange of water masses between the Atlantic Ocean and the Mediterranean Sea. Basin physiography is also a consequence of the Pliocene-Quaternary compression which has progressively uplifted the sourrounding reliefs and deforms the interior and the margins of the basin. On this scenario, several submarine canyons and gullies have been developed in this basin which traverse especially the northern margin and the flanks of the Northern Alboran Ridge, without affecting the African margins. This fact must be related to the action of bottom contour currents which constitute the main morpho-sedimentary process. The influence of water masses distributed the sedimentary input carried by rivers and coming from the erosion of surrounding ranges. In the southern margin of this basin this influence is stronger and inhibits the development of transversal submarine canyons

The extradomain a of fibronectin enhances the efficacy of lipopolysaccharide defective Salmonella bacterins as vaccines in mice

The Extradomain A from fibronectin (EDA) has an immunomodulatory role as fusion protein with viral and tumor antigens, but its effect when administered with bacteria has not been assessed. Here, we investigated the adjuvant effect of EDA in mice immunizations against Salmonella enterica subspecies enterica serovar Enteritidis (Salmonella Enteritidis). Since lipopolysaccharide (LPS) is a major virulence factor and the LPS O-polysaccharide (O-PS) is the immunodominant antigen in serological diagnostic tests, Salmonella mutants lacking O-PS (rough mutants) represent an interesting approach for developing new vaccines and diagnostic tests to differentiate infected and vaccinated animals (DIVA tests). Here, antigenic preparations (hot-saline extracts and formalin-inactivated bacterins) from two Salmonella Enteritidis rough mutants, carrying either intact (SE Delta waaL) or deep-defective (SE Delta gal) LPS-Core, were used in combination with EDA. Biotinylated bacterins, in particular SE Delta waaL bacterin, decorated with EDAvidin (EDA and streptavidin fusion protein) improved the protection conferred by hot-saline or bacterins alone and prevented significantly the virulent infection at least to the levels of live attenuated rough mutants. These findings demonstrate the adjuvant effect of EDAvidin when administered with biotinylated bacterins from Salmonella Enteritidis lacking O-PS and the usefulness of BEDA-SE Delta waaL as non-live vaccine in the mouse model.This work was funded by Gobierno de Navarra and European Union (project EuroInnova-Navarra reference IIM10865.RI1-EP12).

Utilización de los medios audiovisuales aplicados a las Ciencias Sociales

Comparar la adquisición de conocimientos y actitud de un mismo grupo en temas distintos, trabajados con o sin audiovisuales. Incorporar al conocimiento físico e histórico del medio la utilización de los aparatos técnicos y el aprendizaje del lenguaje de la imagen por parte del alumno. 69 alumnos de sexto de EGB del Colegio Público Llibertat de Badalona repartidos en dos grupos de 35 y 34 alumnos respectivamente. Recogida de datos del rendimiento y aprendizaje de los temas ya trabajados sin audiovisuales. Se realiza la evaluación del proceso de trabajo llevado a cabo por los alumnos y de la adquisición de conocimientos del entorno. Finalmente, se pasa una encuesta de valoración a los alumnos sobre el nuevo método de trabajo experimentado en Ciencias Sociales, incluyendo aspectos de autoevaluación. Variable dependiente: rendimiento. Prueba de rendimiento ad hoc. Encuesta ad hoc. Observación participativa. Trabajos presentados por los alumnos. Frecuencia. Media. Polígonos de frecuencia. La respuesta a la hipótesis planteada, hay diferencia en el aprendizaje de las Ciencias Sociales si se trabaja con o sin audiovisuales, aun no teniendo criterios suficientemente objetivables, es afirmativa en cuanto que hay un mejor y más profundo conocimiento del medio y en general una mayor motivación por toda la asignatura si se trabaja con medios audiovisuales.
