Una fiesta y varias fronteras: los Quintos de Barrancos (Portugal) y Noblejas (España)
En este artículo intentamos ensayar una perspectiva comparativa sobre la fiesta de los quintos en dos municipios distintos, uno en España y otro en Portugal. Para ello analizamos en primer lugar las formas en que se desarrolla la fiesta en ambos casos, señalando las coincidencias y diferencias que existen en la propia celebración. A partir de aquí se desarrolla el análisis comparativo, para el que se introduce una doble perspectiva: el pueblo y la villa como escenarios de la convivencia, y la fiesta como frontera en un sentido espacial y también temporal. Por último, se exponen algunas conclusiones sobre lo que se revela en la comparación
Extracorporeal cytokine hemadsorption for the treatment of refractory septic shock. Report of two cases
Indexación: Scopus.If Septic shock (SS) evolves to refractory SS, mortality could reach 90%, despite giving an optimal treatment. Nowadays, extracorporeal devices which adsorb inflammatory cytokines are available, reducing the systemic inflammatory response syndrome. These devices can be used with continuous renal replacement therapy or conventional hemodialysis. We report two diabetic females aged 50 and 58 years, who underwent a total colectomy and amputation of diabetic foot and who developed a SS with high requirements of vasoactive drugs (norepinephrine and adrenaline) to maintain a mean arterial pressure about 60 mmHg. Both were subjected to hemodialysis, connected to a cytokine hemadsorption device. The most important finding was the progressive reduction of vasopressor doses, effect that was observed nine hours after the beginning of the hemadsorption and lasted until its removal at 26 hours. Both patients survived. © 2018, Sociedad Medica de Santiago. All rights reserved.https://scielo.conicyt.cl/scielo.php?script=sci_arttext&pid=S0034-98872018000600796&lng=en&nrm=iso&tlng=e

Optimización de tratamientos a baja temperatura para incrementar fenoles hidrofílicos en la fracción líquida de Alperujo
Hydrophilic phenols are the main bioactive compounds in alperujo. Among them, 3,4-Dihydroxyphenylglycol (DHPG), Hydroxytyrosol (HT) and Tyrosol (Ty), are the most relevant and deeply studied. These compounds exhibit high antioxidant capacity and a wide range of health benefits as well as technologically promising properties. Given that, their recovery represents an attractive opportunity to valorize this by-product. In this work low thermal treatments were applied to alperujo in order to obtain phenol-enriched liquid fractions. Optimization assays combining different levels of temperature (30 to 90 ºC), time (60 to 180 min) and water content (70 to 90%), followed by response surface methodologies were performed. The results indicated that by applying optimal conditions, is possible to obtain theoretical yields of Total phenols, DHPG, HT and Ty of 2.4, 957.8, 3.4 and 6.4 times greater, respectively, than raw dry alperujo. Interestingly, all the evaluated conditions can be reproduced with low investment in a standard olive oil industry.Los fenoles hidrofílicos representan los principales compuestos bioactivos del alperujo. Los más relevantes son 3,4-Dihidroxifenilglicol (DHFG), Hidroxitirosol (HT) y Tirosol (Ti). Estos compuestos presentan alta capacidad antioxidante, beneficios para la salud e importantes propiedades tecnológicas, por ello su recuperación representa una alternativa para la valorización de este subproducto. En este trabajo, se aplicaron al alperujo tratamientos térmicos para obtener fracciones líquidas enriquecidas con compuestos fenólicos. Se realizaron ensayos combinando niveles de temperatura (30 ºC a 90 ºC), tiempo (60 min a 180 min) y humedad del alperujo (70 % a 90 %), seguidos de metodologías de superficie de respuesta. Los resultados indicaron que, mediante la aplicación de las condiciones óptimas, es posible obtener rendimientos teóricos de fenoles totales, DHFG, HT y Ti, 2.4, 957.8, 3.4 y 6.4 veces superiores a los obtenidos a partir del alperujo inicial. Es destacable que las condiciones establecidas, se pueden reproducir con bajo costo en una industria olivícola estándar

Supersymmetric free-damped oscillators: Adaptive observer estimation of the Riccati parameter
A supersymmetric class of free damped oscillators with three parameters has
been obtained in 1998 by Rosu and Reyes through the factorization of the Newton
equation. The supplementary parameter is the integration constant of the
general Riccati solution. The estimation of the latter parameter is performed
here by employing the recent adaptive observer scheme of Besancon et al., but
applied in a nonstandard form in which a time-varying quantity containing the
unknown Riccati parameter is estimated first. Results of computer simulations
are presented to illustrate the good feasibility of this approach for a case in
which the estimation is not easily accomplished by other meansComment: 8 pages, 6 figure

Impact of Local Congruences in Attribute Reduction
Local congruences are equivalence relations whose equivalence classes are convex sublattices of the original lattice. In this paper,
we present a study that relates local congruences to attribute reduction
in FCA. Specifically, we will analyze the impact in the context of the use
of local congruences, when they are used for complementing an attribute
reduction
