    Background: The relationship between emotional intelligence (EI) and stress has been widely studied, as well as the beneficial role of self-care to maintain health and wellbeing. However, the joint contribution of EI and self- care in predicting stress has not been examined during COVID-19 lockdown. This study aimed to examine the mediating role of self-care in the relationship between EI and stress and the potential moderator role of gender. Methods: A sample of 1082 participants from four Hispanic countries completed measures related to socio- demographic, trait emotional intelligence (Trait Meta-Mood Scale), self-care activities (Self-care Activities Screening Scale) and stress (Perceived Stress Scale). Results: Mediation analyses revealed that self-care increased the explained variance of the prediction of stress by EI dimensions after controlling gender and age. However, gender only moderated the relationship between selfcare and stress in the mediation model corresponding to emotional attention. Conclusions: Data supported a general model for the interaction of EI and self-care as contributing factors of stress. Further research is needed to replicate it in more culturally distant samples and to fully explore the po- tential role of gender differences. Future intervention programs should include a balanced combination of EI and self-care to increase their benefits on people’s healt

    Parental Burnout Around the Globe: a 42-Country Study

    High levels of stress in the parenting domain can lead to parental burnout, a condition that has severe consequences for both parents and children. It is not yet clear, however, whether parental burnout varies by culture, and if so, why it might do so. In this study, we examined the prevalence of parental burnout in 42 countries (17,409 parents; 71% mothers; M_{age} = 39.20) and showed that the prevalence of parental burnout varies dramatically across countries. Analyses of cultural values revealed that individualistic cultures, in particular, displayed a noticeably higher prevalence and mean level of parental burnout. Indeed, individualism plays a larger role in parental burnout than either economic inequalities across countries, or any other individual and family characteristic examined so far, including the number and age of children and the number of hours spent with them. These results suggest that cultural values in Western countries may put parents under heightened levels of stress

    Optimization of the CRTM process by means of monitoring techniques

    In this work the feasability of the monitoring system, composed of flow-rate and injection pressure sensors, in addition to the pressure sensors integrated in the mold, is demonstrated to determine the optimal process window of the CRTM (Compression Resin Transfer Molding). The sensors of the injector allow monitoring of the injection phase, while the pressure sensors integrated in the mold allow the phases of the compression and the curing to be followed. In order to relate the pressure sensor variations with the curing phase, an electric current sensor has been used. The increase of the resistance, associated with the beginning of curing, corresponds in time with the pressure drop, which in turn is justified by the contraction generated during curing. This pressure drop reaches a horizontal asymptote which corresponds to a conversion rate of 40%. Based on this behavior of the pressure sensor, it is possible to determine the minimum time for the demoulding of each of the pieces. Finally, the system has been used to monitor the manufacturing of prototypes with curing temperatures between 80-120 ºC, and it has been confirmed that the sensors identify the parts that are inside the process window and those that are not

    The present work presents a preliminary study on the development of a tubular chassis design for automotive industry manufactured with ultraviolet (UV) 3D pultrusion. The use of straight profiles for energy absorption elements and the advantages and feasibility of using curved profiles in other structural areas have been analysed. For the straight profiles, the energy absorption cabability of the material (specific energy absorption, SEA) has been evaluated performing quasi-static compression tests, showing high energy dissipation values, over 50 kJ / kg. On the other hand, the manufacturing of curved profiles by UV pultrusion have been analysed, evaluating the influence of the processing parameters (emitting intensity and pulling speed) and the influence of the reinforcement type on the geometry of the profile. It has been observed that the roving reinforcement allows an easier manipulation and allows to obtain curves without wrinkles with complex sections, due to the free movement between yarns; while the tape reinforcement may present wrinkles during the curving stage. In addition, based on a design with straight profiles, it has been shown that using non-rectilinear profiles, a significant reduction of the necessary connection nodes can be achieved, reducing up to 75% the number of connection nodes based on the analyed design

    Valencia del Ventoso Massif (MW), (south Badajoz, Spain), is a late-hercynical inversely zonated pluton, composed by a wide range of lithologies, from ultramafic to granitic rocks. Landsat TM images has been digitally treated to verify satellitariah potential as a tool for cartographying plutons like MW. The treatment, based on the analysis of 6 bands' over the visible and near infrarred electromagnetic spectrum, has yield successful results, specially, on delimiting the contact, linear structures, and up to some extent, pluton inside and next lithdlogical bodie
