    A detailed chemistry model for transient hydrogen and carbon monoxide catalytic recombination on parallel flat Pt surfaces implemented in an integral code

    Full text link
    A detailed chemistry model has been adapted and developed for surface chemistry, heat and mass transfer between H2/CO/air/steam/CO2 mixtures and vertical parallel Pt-coated surfaces. This model is based onto a simplified Deutschmann reaction scheme for methane surface combustion and the analysis by Elenbaas for buoyancy-induced heat transfer between parallel plates. Mass transfer is treated by the heat and mass transfer analogy. The proposed model is able to simulate the H2/CO recombination phenomena characteristic of parallel-plate Passive Autocatalytic Recombiners (PARs), which have been proposed and implemented as a promising hydrogen-control strategy in the safety of nuclear power stations or other industries. The transient model is able to approach the warm-up phase of the PAR and its shut-down as well as the dynamic changes within the surrounding atmosphere. The model has been implemented within the MELCOR code and assessed against results of the Battelle Model Containment tests of the Zx series. Results show accurate predictions and a better performance than traditional methods in integral codes, i.e., empirical correlations, which are also much case-specific. Influence of CO present in the mixture on the PAR performance is also addressed in this paper

    Adult Attachment, Conflict Resolution Style and Relationship Quality among Spanish Young-adult Couples

    The evidence of the interrelationships between adult attachment, conflict resolution style and relationship quality in couple relationships shows some inconsistencies and it is mostly based on English-speaking adult samples, as well as on individuals’ rather than on both couple members’ reports. Therefore, the aim was to examine the associations between adult attachment, conflict resolution style and relationship quality from a dyadic approach. A sample of 405 heterosexual young couples completed online the brief version of the Experiences in Close Relationships-Revised Questionnaire, the respondent version of the Conflict Resolution Styles Inventory, and a 4-item measure of relationship quality. Avoidance attachment showed a stronger negative correlation than anxiety with relationship quality. Withdrawal and conflict engagement styles were more highly correlated with avoidance and anxiety, respectively. At a dyadic level, relationship quality was negatively predicted by actor avoidance attachment and positively predicted by partner relationship quality. No actor or partner effects of conflict resolution style on relationship quality were observed. Overall, partners with higher attachment anxiety and avoidance reported more dysfunctional conflict resolution styles and less satisfaction with the relationship

    Resumen: En este trabajo se pretende hacer un análisis sobre la formación del profesorado en educación sexual en todo el territorio nacional. Para valorar esta formación se ha recogido información on line de 3760 docentes activos del conjunto del estado, de las etapas de Infantil, Primaria, Secundaria y Bachillerato, sobre la formación universitaria y continua que tienen en este campo. Los resultados mostraron diferencias importantes en la formación universitaria, siendo las mujeres, los/las más jóvenes y los/las que imparten docencia en las etapas de Infantil y/o Primaria (en comparación a los hombres, los/las de más edad y los/las que imparten docencia en ESO y/o Bachillerato) los que manifestaron tener mayor formación. Por comunidades autónomas, los docentes de Castilla y León son los que manifestaron tener más formación universitaria y los de Asturias los que manifestaron haber recibido más formación continua. En el lado opuesto figuran Asturias y Baleares, respectivamente. Finalmente, se aportan sugerencias de mejora tanto en el ámbito de la formación universitaria como de la formación continua.Abstract: The main purpose of this article is to evaluate the level of sex education training of Spanish teachers. A total of 3760 preschool, primary and high school teachers throughout the country completed an on-line questionnaire that inquires about sex education training both during university studies and continuous learning. Results showed differences at the level of university studies. Younger and female preschool and school teachers reported a higher level of training in sex education compared to older and male high school teachers. Moreover, regional differences were found both in university and continuous training. Teachers from Castilla y León showed the greatest levels of university training in sex education, whereas teachers from Asturias showed the greatest levels of continuous training. Asturian and Balearic teachers were on the opposite side, respectively. Finally, suggestions for improvement both in the field of university education and continuous training are offered
