Studies on the power factor of (Ba,Sr)Co2+xRu4−xO11 compounds

[Abstract] We have prepared polycrystalline single-phase ACo2+xRu4−xO11 (A = Sr, Ba; 0 ≤ x ≤ 0.5) using the ceramic method and we have studied their structure, electrical resistivity and Seebeck coefficient, in order to estimate their power factor (P.F.). These layered compounds show values of electrical resistivity of the order of 10−5 Ωm and their Seebeck coefficients are positive and range from 1 μV K−1 (T = 100 K) to 20 μV K−1 (T = 450 K). The maximum power factor at room temperature is displayed by BaCo2Ru4O11 (P.F.: 0.20 μW K−2 cm−1), value that is comparable to that shown by compounds such as SrRuO3 and Sr6Co5O15.Ministerio de Ciencia e Innovación; Project FEDER MAT 2007-6669

Antecedentes de los valores olímpicos en la Grecia Clásica y su proyección en el olimpismo moderno

Actualmente, el Movimiento Olímpico identifica tres valores fundamentales que definen el Olimpismo: excelencia, amistad y respeto. Muchas investigaciones analizan la inclusión de los valores olímpicos en los textos y conferencias de Pierre de Coubertin, sin embargo, poco se ha escrito sobre los valores asociados a la práctica física y competitiva en la Grecia Clásica y la vinculación de estos con los valores del ideario olímpico moderno. Este trabajo estudia la pervivencia de aquellos valores clásicos dentro de los que hoy recoge el Movimiento Olímpico y cómo podemos establecer un paralelismo entre los valores defendidos por el Olimpismo moderno y el código ético subyacente en la literatura grecolatina, en cuanto a la actividad física y la celebración de los certámenes atléticos.---------------------------------------------------------------------------------Currently, the Olympic Movement has identified three core values that define Olympism: excellence, friendship and respect. Many studies analyzed the inclusion of the olympic values in texts and lectures of Pierre de Coubertin, however, little has been written about the values associated with the physical and competitive practice in Classical Greece and linking these with the values of ideology modern olympic. This article studies the survival of those classic values within which today includes the Olympic Movement and how we can establish a parallelism between the values defended by the modern Olympism and the underlying ethical code in the Greco-Roman literature regarding physical activity and celebration athletic contests. Artículo revisado por pare

Atypical magnetic behavior in the incommensurate [CH3NH3][Ni(HCOO)3][CH_3NH_3][Ni(HCOO)_3] hybrid perovskite

A plethora of temperature induced phase transitions have been observed in $[CH_3NH_3][M(HCOO)_3]$ compounds, where M is Co(II) or Ni(II). Among them, the nickel compound exhibits a combination of magnetic and nuclear incommensurabil-ity below N\'eel temperature. Despite the fact that the zero-field behavior has been previously addressed, here we study in depth the macroscopic magnetic behavior of this compound to unveil the origin of the atypical magnetic response found in it and in its parent family of formate perovskites. In particular, they show a puzzling magnetization reversal in the curves measured starting from low temperatures, after cooling under zero field. The first atypical phenomena is the im-possibility of reaching zero magnetization, even by nullifying the applied external field and even compensating it for the influence earth's magnetic field. Relatively large magnetic fields are needed to switch the magnetization from negative to positive values or vice versa, which is compatible with a soft-ferromagnetic system. The atypical path found in its first magnetization curve and hysteresis loop at low temperatures is the most noticeable feature. The magnetization curve switches from more than 1200 Oe from the first magnetization loop to the subsequent magnetization loops. A feature that cannot be explained using a model based on unbalanced pair of domains. As a result, we decipher this behavior in light of the incommensurate structure of this material. We propose, in particular, that the applied magnetic field induces a mag-netic phase transition from a magnetically incommensurate structure to a magnetically commensurate structure.Comment: 9 pages, 7 figures, 1 tabl

Impact and Learner Experience of a Technology Ecosystem as an Approach to Healthy Lifestyles: Erasmus+ SUGAPAS Project

The promotion of lifestyle habits in all ages is essential for the prevention of chronic non-communicable diseases. The aim of this study was to develop, validate, and disseminate an ecosystem that favors effective education on physical activity, a healthy lifestyle, and healthy nutritional habits. The sample consisted of 258 Spanish volunteer students. The evaluation of Ecosystem SUGAPAS was composed of two online surveys: MOOC and game surveys. The result of the MOOC survey reported a score above three points in all the sections (users’ opinion of the organization: 3.89 ± 0.71, 4.06 ± 0.64, and 4.01 ± 0.64; impact of the course on their day-to-day life: 3.62 ± 0.94; content present values: 3.96 ± 0.63, 3.69 ± 0.75, and 3.62 ± 0.94; usability of the platform: 3.75 ± 0.77, 3.96 ± 0.68, 4.06 ± 0.77, and 3.75 ± 0.84; relevance for professional development: 3.96 ± 0.63; overall opinion: 3.77 ± 0.57 points). The responses to all sections of the game evaluation reported a score between three and four points. A SUGAPAS ecosystem that includes new technologies for the promotion of a healthy lifestyle was developed, validated, and disseminated among the population. The users’ opinion, the impact of the ecosystem on their personal and professional development, and the usability of the platforms created make this ecosystem valid for its implementation for the proposed purposes

Exploring the perception of barriers to a dual career by student-athletes with/out disabilities

n recent years, there has been an increase in knowledge about the barriers experienced by people with disabilities in the education system or sports. However, no studies have analyzed the barriers for those who try to succeed in both disciplines (dual career). The purpose of this study was to examine the barriers faced by student-athletes with/out disability to a dual career combining studies and sport. Two groups were involved in the study (n = 162): student-athletes with disabilities (n = 79) and student-athletes without disabilities (n = 83). Data collected included: (a) socio-demographic aspects; and (b) barriers towards achieving a good balance between sport and academics during the dual career, through the "Perceptions of dual career student-athletes" (ESTPORT) questionnaire. The results showed that student-athletes with disabilities were more likely to perceive in a greater extent the barriers, the university is far from my home (p = 0.007) and the university is far from my training site (p = 0.006), I find myself unable to balance study and training time (p = 0.030), I have to take care of my family (p<0.001), and my current job does not allow me to study enough (p<0.001). The MANOVA analysis showed that the factors gender, competitive level, and employment status had an influence on the perception of some barriers between groups. In conclusion, student-athletes with disabilities perceived barriers more strongly than those without disabilities, and measures are needed to ensure their inclusion in the education system

Implementing the European Sports Leadership Programme: A vehicle to help development graduate workplace competencies

This research was part of a large intervention study implementing the European Sports Leadership Programme (ESLP). This paper reports the outcomes of the qualitative study that employed focus groups to assess the students’ perceptions of the 15 competencies determined according to the Framework for qualifications of the European Higher Education Area, before and after the ESLP. Focus groups were carried out at each of the five universities. The ESLP involved university students working as a sports leader for 24 months with the aim to engage more students in university sport, whilst they took part in a graduate employability programme. Each university recruited five sports leaders in their second year at university, to deliver 10 new sport and recreational activities targeting the wider inactive or semi-active student population. Findings highlighted that Organization and planning, Oral and written communication, Development of planning and decision making, and Teamworking, followed closely by Emotional control and Adapting to new situations, were the most commonly reported competencies. They affirmed that this programme had helped to develop these competencies. Use of information, communication and technology, Communication in a foreign language, Research and Emotional control were the most common competencies that students stated they needed to improve further. This research found that implementing the ESLP helped to develop students’ perceptions of their workplace and career competencies. The ESLP is therefore, recommended as one approach to helping universities to develop student’s workplace and career competencies

Development of an activity disease score in patients with uveitis (UVEDAI)

To develop a disease activity index for patients with uveitis (UVEDAI) encompassing the relevant domains of disease activity considered important among experts in this field. The steps for designing UVEDAI were: (a) Defining the construct and establishing the domains through a formal judgment of experts, (b) A two-round Delphi study with a panel of 15 experts to determine the relevant items, (c) Selection of items: A logistic regression model was developed that set ocular inflammatory activity as the dependent variable. The construct "uveitis inflammatory activity" was defined as any intraocular inflammation that included external structures (cornea) in addition to uvea. Seven domains and 15 items were identified: best-corrected visual acuity, inflammation of the anterior chamber (anterior chamber cells, hypopyon, the presence of fibrin, active posterior keratic precipitates and iris nodules), intraocular pressure, inflammation of the vitreous cavity (vitreous haze, snowballs and snowbanks), central macular edema, inflammation of the posterior pole (the presence and number of choroidal/retinal lesions, vascular inflammation and papillitis), and global assessment from both (patient and physician). From all the variables studied in the multivariate model, anterior chamber cell grade, vitreous haze, central macular edema, inflammatory vessel sheathing, papillitis, choroidal/retinal lesions and patient evaluation were included in UVEDAI. UVEDAI is an index designed to assess the global ocular inflammatory activity in patients with uveitis. It might prove worthwhile to motorize the activity of this extraarticular manifestation of some rheumatic diseases

Dissecting the Shared Genetic Architecture of Suicide Attempt, Psychiatric Disorders, and Known Risk Factors

BACKGROUND: Suicide is a leading cause of death worldwide, and nonfatal suicide attempts, which occur far more frequently, are a major source of disability and social and economic burden. Both have substantial genetic etiology, which is partially shared and partially distinct from that of related psychiatric disorders. METHODS: We conducted a genome-wide association study (GWAS) of 29,782 suicide attempt (SA) cases and 519,961 controls in the International Suicide Genetics Consortium (ISGC). The GWAS of SA was conditioned on psychiatric disorders using GWAS summary statistics via multitrait-based conditional and joint analysis, to remove genetic effects on SA mediated by psychiatric disorders. We investigated the shared and divergent genetic architectures of SA, psychiatric disorders, and other known risk factors. RESULTS: Two loci reached genome-wide significance for SA: the major histocompatibility complex and an intergenic locus on chromosome 7, the latter of which remained associated with SA after conditioning on psychiatric disorders and replicated in an independent cohort from the Million Veteran Program. This locus has been implicated in risk-taking behavior, smoking, and insomnia. SA showed strong genetic correlation with psychiatric disorders, particularly major depression, and also with smoking, pain, risk-taking behavior, sleep disturbances, lower educational attainment, reproductive traits, lower socioeconomic status, and poorer general health. After conditioning on psychiatric disorders, the genetic correlations between SA and psychiatric disorders decreased, whereas those with nonpsychiatric traits remained largely unchanged. CONCLUSIONS: Our results identify a risk locus that contributes more strongly to SA than other phenotypes and suggest a shared underlying biology between SA and known risk factors that is not mediated by psychiatric disorders

Genome-wide association study identifies 30 Loci Associated with Bipolar Disorder

This paper is dedicated to the memory of Psychiatric Genomics Consortium (PGC) founding member and Bipolar disorder working group co-chair Pamela Sklar. We thank the participants who donated their time, experiences and DNA to this research, and to the clinical and scientific teams that worked with them. We are deeply indebted to the investigators who comprise the PGC. The views expressed are those of the authors and not necessarily those of any funding or regulatory body. Analyses were carried out on the NL Genetic Cluster Computer (http://www.geneticcluster.org ) hosted by SURFsara, and the Mount Sinai high performance computing cluster (http://hpc.mssm.edu).Bipolar disorder is a highly heritable psychiatric disorder. We performed a genome-wide association study including 20,352 cases and 31,358 controls of European descent, with follow-up analysis of 822 variants with P<1x10-4 in an additional 9,412 cases and 137,760 controls. Eight of the 19 variants that were genome-wide significant (GWS, p < 5x10-8) in the discovery GWAS were not GWS in the combined analysis, consistent with small effect sizes and limited power but also with genetic heterogeneity. In the combined analysis 30 loci were GWS including 20 novel loci. The significant loci contain genes encoding ion channels, neurotransmitter transporters and synaptic components. Pathway analysis revealed nine significantly enriched gene-sets including regulation of insulin secretion and endocannabinoid signaling. BDI is strongly genetically correlated with schizophrenia, driven by psychosis, whereas BDII is more strongly correlated with major depressive disorder. These findings address key clinical questions and provide potential new biological mechanisms for BD.This work was funded in part by the Brain and Behavior Research Foundation, Stanley Medical Research Institute, University of Michigan, Pritzker Neuropsychiatric Disorders Research Fund L.L.C., Marriot Foundation and the Mayo Clinic Center for Individualized Medicine, the NIMH Intramural Research Program; Canadian Institutes of Health Research; the UK Maudsley NHS Foundation Trust, NIHR, NRS, MRC, Wellcome Trust; European Research Council; German Ministry for Education and Research, German Research Foundation IZKF of Münster, Deutsche Forschungsgemeinschaft, ImmunoSensation, the Dr. Lisa-Oehler Foundation, University of Bonn; the Swiss National Science Foundation; French Foundation FondaMental and ANR; Spanish Ministerio de Economía, CIBERSAM, Industria y Competitividad, European Regional Development Fund (ERDF), Generalitat de Catalunya, EU Horizon 2020 Research and Innovation Programme; BBMRI-NL; South-East Norway Regional Health Authority and Mrs. Throne-Holst; Swedish Research Council, Stockholm County Council, Söderström Foundation; Lundbeck Foundation, Aarhus University; Australia NHMRC, NSW Ministry of Health, Janette M O'Neil and Betty C Lynch
