    Nonperturbative Model Of Liouville Gravity

    Full text link
    We obtain nonperturbative results in the framework of continuous Liouville theory. In particular, we express the specific heat Z{\cal Z} of pure gravity in terms of an expansion of integrals on moduli spaces of punctured Riemann spheres. The integrands are written in terms of the Liouville action. We show that Z{\cal Z} satisfies the Painlev\'e I.Comment: 11 pages, LaTex fil

    The statistical data and some studies raise the relevance of the problem of school failure in Spain, the percentages of early abandonment are worrisome. This school failure is related to the lack of acquisition of significant learning due to difficulties in learning, relationships with peers, insufficient reading comprehension, …; these generate erroneous perceptions and negative emotions that influence school performance. Therefore, it is important to evaluate the relationship between the different aspects that allow us to promote the learning of social skills in a preventive manner. In this research we have used a relational model between perception and performance in the subject natural sciences and social skills of consciousness and emotional control, conversational, cooperation and help through work, those related to the defense of own rights, socio-emotional and life and subjective well-being as improvement of the quality of life. The sample of the research is 447 students from the third to sixth year Primary courses from several educational centers. The results obtained show us that there is significance between perception and socio-emotional skills with respect to performance and, therefore, the motivational impulse in performance is proven if we improve perception through these socio-emotional skills and the development in the classroom of programs and active methodologies, as cooperative learning and mindfulness, that improve learning and reduce conflicts in the classroom.Los datos estadísticos y algunos estudios nos plantean la relevancia del problema del fracaso escolar en España, los porcentajes de abandono temprano son preocupantes. Este fracaso escolar se relaciona con la no adquisición de un aprendizaje significativo debido a las dificultades en el aprendizaje, a las relaciones con sus compañeros, a la escasa comprensión lectora, etc.: estos generan percepciones erróneas y emociones negativas que influyen en el rendimiento escolar. Por ello, es importante evaluar la relación entre los diferentes aspectos que nos permitan fomentar el aprendizaje de habilidades sociales de forma preventiva. En esta investigación hemos utilizado un modelo relacional entre la percepción y el rendimiento en la asignatura ciencias de la naturaleza y las habilidades sociales de toma de conciencia y control emocional, conversacionales, la cooperación y ayuda mediante el trabajo, las relacionadas con la defensa de los propios derechos, las socio - emocionales y de vida y bienestar subjetivo como mejora de la calidad de vida. La muestra de la investigación es de 445 estudiantes de los cursos de tercero a sexto de Primaria de varios centros educativos. Los resultados obtenidos nos muestran que existe significatividad entre la percepción y las habilidades socio - emocionales con respecto al rendimiento y, por lo tanto, se comprueba el impulso motivacional en el rendimiento si mejoramos la percepción mediante dichas habilidades socio – emocionales y el desarrollo en el aula de programas y metodologías activas, como aprendizaje cooperativo y mindfulness, que mejoren el aprendizaje y reduzcan los conflictos en el aula

    In this document we present the methodological design of the research that we carry out in order to analyze the social and educational needs of the mining zones from Asturias. First we show the context of the study, next we explain the objectives and the methodology of the investigation: the study typology, the developed phases in the project, the sources of information, the procedures that we use to collect the information, the samples that we used and the kind of data analysis that have been made. To conclude, and as an example, we present some of the most significant tables and results. The conclusions of the study are presented with detail in another article.En este documento presentamos el diseño metodológico de una investigación que tiene por objeto analizar las necesidades sociales y educativas de las cuencas mineras del Principado de Asturias.

    Plasma IP-10 and IL-6 are linked to Child-Pugh B cirrhosis in patients with advanced HCV-related cirrhosis: a cross-sectional study.

    We aimed to evaluate the association of plasma biomarkers linked to inflammation (bacterial translocation, inflammatory response, and endothelial dysfunction), coagulopathy, and angiogenesis with the severity of liver cirrhosis (assessed by the Child-Pugh-Turcotte score, CTP) and Child-Pugh B cirrhosis (CTP 7-9) in patients with advanced hepatitis C virus (HCV)-related cirrhosis. We carried out a cross-sectional study in 97 patients with advanced HCV-related cirrhosis (32 HCV-monoinfected and 65 HIV/HCV-coinfected). Plasma biomarkers were measured by ProcartaPlex multiplex immunoassays. The outcome variable was the CTP score and the Child-Pugh B cirrhosis (CTP 7-9). HIV/HCV-coinfected patients and HCV-monoinfected patients with advanced HCV-related cirrhosis had near-equivalent values of plasma biomarkers. Higher values of plasma biomarkers linked to an inflammatory response (IP-10, IL-8, IL-6, and OPG), endothelial dysfunction (sVCAM-1 and sICAM-1), and coagulopathy (D-dimer) were related to higher CTP values. The most significant biomarkers to detect the presence of Child-Pugh B cirrhosis (CTP 7-9) were IP-10 (p-value= 0.008) and IL-6 (p-value=0.002). The AUC-ROC values of IP-10, IL-6, and both biomarkers combined (IP-10+IL-6) were 0.78, 0.88, and 0.96, respectively. In conclusion, HIV infection does not appear to have a significant impact on the analyzed plasma biomarkers in patients with advanced HCV-related cirrhosis. However, plasma biomarkers linked to inflammation (inflammatory response and endothelial dysfunction) were related to the severity of liver cirrhosis (CTP score), mainly IP-10 and IL-6, which discriminated patients with Child-Pugh B concerning Child-Pugh A.The HIV BioBank, is supported by Instituto de Salud Carlos III, Spanish Health Ministry (Grant n° RD06/0006/0035, RD12/0017/0037 and RD16/0025/0019) as part of the Plan Nacional R + D + I and cofinanced by ISCIII- Subdirección General de Evaluación y el Fondo Europeo de Desarrollo Regional (FEDER)”.
