El aislamiento de base es una técnica de protección sismorresistente para edificaciones, con amplio y exitoso uso a nivel mundial. En Colombia actualmente existen algunos edificios que incorporan esta técnica, los cuales fueron diseñados bajo los requisitos de la normativa americana vigentes en la época, como ASCE 7-10. Dicho documento ha sido recientemente actualizado a su versión 2016, con importantes cambios técnicos respecto a su predecesor. ASCE 7-16 incorpora resultados de las investigaciones más recientes en cuanto a aislamiento sísmico se refiere; en consecuencia, las futuras edificaciones que empleen esta técnica y que sean diseñadas y construidas en el país deberían seguir dicha regulación. Por todo lo anterior, en el presente trabajo se evidencia la necesidad de hacer un análisis de esta nueva estrategia de diseño (para edificaciones con aislamiento de base) y discutir su aplicabilidad en el país., Base isolation is a successful and worldwide used seismic protection technique for buildings. In Colombia there are some buildings that incorporate this technology; were designed by following the current American regulations, namely ASCE 7-10. This document has been recently updated to its 2016 version, with important changes. ASCE 7-16 incorporates the results of the most recent research; thus, apparently, future isolated buildings should follow this document. These considerations highlight the necessity of analyzing the prescriptions of ASCE 7-16 (regarding base isolation of buildings) and discussing its applicability to Colombia., Peer Reviewed, Postprint (published version)

Productes de coneixement, El Equipo de Asesoramiento Técnico Civil en el Ámbito de la Familia (EATAF) da respuesta a las peticiones judiciales de asesoramiento técnico de los juzgados que actúan en materia de familia, en casos de separación o conflicto, con hijos menores de edad , a fin de proponer las medidas de organización familiar más adecuadas en cada situación. En continuidad con el producto de conocimiento colaborativo de 2011 Guía de Intervención con menores, documento de buenas prácticas para la intervención con los niños en los procedimientos judiciales, la CoP creyó conveniente crear un decálogo propio, que pudiera invitar a la buena práctica del divorcio a aquellos que han decidido elegir esa opción. Durante 2013 y 2014, los profesionales concibieron el decálogo “Padres, yo no me separo.”, en formato de díptico y cartel, junto con un plan de sensibilización y de difusión en formato de taller, dirigido a adultos y profesionales, por promover, desde la visión del niño, las buenas prácticas en situaciones de divorcio., info:eu-repo/semantics/publishedVersion

Methods: We investigated this process comparing two different high-fat dietary approaches to induce obesity, in which all rats received about 40% of their energy intake as lipids. The main nutrient difference between the diets, when compared with controls fed standard lab chow, was the lipid content. Cafeteria diets (K) were devised to be tasty, and thus highly desirable to the rats, mainly for its diverse mix of tastes, particularly salty and sweet. This diet was compared with another high-fat (HF) potentially obesogenic diet, devised not to be as tasty as K, and prepared just supplementing standard chow pellets with fat. We also analysed the influence of sex on the effects of the diets. Results: K rats grew faster, especially the males, although females showed a higher proportion of body lipid, because of a high lipid, sugar and protein intake. HF weight change rates were not different from those of controls. In addition to high sugar, K rats also ingested large amounts of salt. With this study we have shown that the key factor eliciting the excess energy intake in a high-energy diet rat model was not solely or mainly their fat intake. The changes in body fat accrual were more a consequence of their appetence for the food. Conclusions: The results show that the significant presence of sugar and salt is a powerful factor promoting excess food intake, more effective than increasing diet lipid content. These effects were already observed after a relatively short treatment, additionally confirming the differential effects of sex on the hedonic and obesogenic response to diet.

CEIPAC, Universidad de Barcelona., Los dendrogramas son una nueva herramienta de estudio que nos permite organizar los sellos de un determinado taller de manera más eficiente que la que conseguimos con los corpora o catálogos tradicionales. La idea es generar un sistema epigráficamente lógico y eminentemente gráfico que agrupa los sellos a partir de sus contenidos y los organiza con un esquema: FAMILIA → ESTRUCTURA → LECTURA → MATRIZ. Con este tipo de organización de los datos tendremos desplegados todos los elementos que necesitamos conocer para interpretar la serie y reconstruir, al menos, la parte del sistema organizativo del taller que ha llegado hasta nosotros.

White adipose tissue (WAT) is a complex, diffuse, multifunctional organ which contains adipocytes, and a large proportion of fat, but also other cell types, active in defence, regeneration and signalling functions. Studies with adipocytes often require their isolation from WAT by breaking up the matrix of collagen fibres, however, it is unclear to what extent adipocyte number in primary cultures correlates with their number in intact WAT, since recovery and viability are often unknown. Experimental design. Epididymal WAT of 4-6 young adult rats was used to isolate adipocytes with collagenase. Careful recording of lipid content of tissue, and all fraction volumes and weights, allowed us to trace the amount of initial WAT fat remaining in the cell preparation. Functionality was estimated by incubation with glucose and measurement of lactate, glycerol and NEFA production. Non-adipocyte cells were also recovered and their sizes (and those of adipocytes) were also measured. The presence of non-nucleated cells (erythrocytes) was also estimated. Results. Cell numbers and sizes were correlated from all fractions to intact WAT. Tracing the lipid content, the recovery of adipocytes in the final, metabolically active, preparation was in the range of 70-75%. Adipocytes were 7%, erythrocytes 68% and other stromal (nucleated cells) 24% of total WAT cells. However, their overall volumes were, 91%, 0.05%, and 0.2% of WAT. Non-fat volume of adipocytes was 2.5% of WAT. Conclusions. The methodology presented here allows for a direct quantitative reference to the original tissue of studies using isolated cells. We have found, also, that the "live cell mass" of adipose tissue is very small (about 25 µL/g for adipocytes and 2 µL/g stromal, plus about 1 µL/g blood). This fact, translates (with respect to the actual "live cytoplasm" size) into an extremely high metabolic activity, which make WAT an even more significant agent in the control of energy metabolism.
