La obligatoriedad de un servicio social y los deberes de solidaridad.
1996
Plantear los límites de actuación del Estado social es lo mismo que los límites en las exigencias de solidaridad. Los deberes jurídicos —y no sólo morales— de la solidaridad van más allá de las contribuciones económicas, alcanzando una contribución personal en términos de tiempo. El autor analiza la coincidencia de tres modelos: servicio civil, voluntariado y trabajadores sociales. El crecimiento de estos dos últimos como consecuencia del Estado asistencial invita a definir los papeles para impulsar el objetivo del Estado social a partir de la ciudadanía socialmente responsable. Índice: La solidaridad como principio jurídico. Solidaridad, Estado social de Derecho y ciudadanía. Los deberes d…

Fructan Biosynthesis by Intra- and Extracellular Zymomonas mobilis Levansucrase after Simultaneous Production of Ethanol and Levan
2003
Summary The chemical composition of the Zymomonas mobilis biomass and the culture liquid after ethanol and levan synthesis were studied. The activities of intra- and extracellular levansucrase produced by the Z. mobilis strain 113 ”S” under optimum conditions both for levan and fructooligosaccharide (FOS) synthesis were also determined. It was shown that levan production relates to the reduction of the carbohydrate and lipid content in the biomass by increasing the nucleic acid and protein content. The levan producing activity of cellular levansucrase after ethanol and levan synthesis was approximately 30–40% of the total activity in the second fermentation stage. It was established that th…
An ethoxylated surfactant enhances the penetration of the sulfated laminarin through leaf cuticle and stomata, leading to increased induced resistanc…
2016
International audience; Some β-1,3-glucans and particularly sulfated laminarin (PS3) are known as resistance inducers (RIs) in grapevine against the downy mildew. However, their efficacy in vineyard is still often too low, which might be caused by a limited penetration through the leaf cuticle following spray application. We used (14) C-sucrose uptake experiments with grapevine leaves in order to select a surfactant as saccharide penetration enhancer. Our results showed that though sucrose foliar uptake was low, it was strongly enhanced by Dehscofix CO125 (DE), a highly ethoxylated surfactant. Fluorescent saccharides were then produced and laser scanning microscopy was used to analyze their…
Monomarentalidad y solidaridad informal. Estrategias contra la exclusión social en el mercado laboral y en la conciliación de la vida familiar
2012
La investigación estudia, desde una perspectiva de género, la realidad de las familias monoparentales encabezadas por una mujer en función de las vías de entrada y el papel de las relaciones de solidaridad informal sobre los procesos de exclusión e integración social en su dimensión económica, referida al mercado laboral y la conciliación trabajo-familia. Para ello, se ha realizado una investigación cualitativa mediante entrevistas en profundidad a19 madres monomarentales de Valencia. Los resultados muestran fuertes evidencias del papel protector de las redes de solidaridad informal frente a la exclusión y la vulnerabilidad social en la dimensión analizada. From a gender perspective, this r…
Characterization of PAMP/PRR interactions in European eel (Anguilla anguilla) macrophage-like primary cell cultures
2013
The eel (Anguilla anguilla) has been identified as a vulnerable species with stocks dramatically declining over the past decade. In an effort to support the species from overfishing of wild stocks increased interest in eel aquaculture has been notable. In order to expand the scarce knowledge concerning the biology of this species significant research efforts are required in several fields of biology. The development of cell culture systems to study the immune response is a key step towards an increased understanding of the immune response and to develop resources to support further study in this threatened species. Macrophages are one of the most important effector cells of the innate immun…
Rainfall timing and runoff: The influence of the criterion for rain event separation
2016
Abstract Rain is not uniform in time and space in semiarid areas and its distribution is very important for the runoff process. Hydrological studies usually divide rainfall into events. However, defining rain events is complicated, and rain characteristics vary depending on how the events are delimited. Choosing a minimum inter-event time (MIT) is a commonly used criterion. Our hypothesis is that there will be an optimal MIT that explains the maximum part of the variance of the runoff, with time to runoff used as a surrogate. The objective is to establish a procedure in order to decide upon this optimal MIT. We developed regressions between time to runoff (T0) and three descriptive variable…

The food industry produces significant amounts of waste, many of them rich in valuable compounds that could be recovered and reused in the framework of circular economy. The development of sustainable and cost-effective technologies to recover these value added compounds will contribute to a significant decrease of the environmental footprint and economic burden of this industry sector.
