Análisis del portero de fútbol = Analysis of the goalkeepe role in soccer

El fútbol ha evolucionado mucho a lo largo de su historia, desde cambios en las propias normas hasta su impacto social en la población. Poco a poco, aunque de una forma bastante lenta, empezamos a darnos cuenta de la importancia que supone el puesto del portero. Esta paulatina transformación se produce para conseguir un mayor rendimiento. Debido a esto, en este trabajo se intentará demostrar los cambios que ha sufrido el portero de fútbol a lo largo de la historia. Centrándonos especialmente en el año 1992, donde se produjo un cambio en la normativa del fútbol, que afectó de una manera muy directa al guardameta, debido a la introducción de la norma de la cesión. Para ello, se han analizado las acciones técnico-tácticas de los partidos de los Mundiales de fútbol desde 1958 hasta el último Mundial de 2014, donde podremos observar la transformación que ha sufrido el portero a lo largo de su vida deportiv

Violencia doméstica: una revisión bibliográfica y bibliométrica

La violencia ejercida entre personas vinculadas por lazos familiares y afectivos ha ganado gran relevancia social en los últimos años. Diversos profesionales han propuesto una gran variedad de conceptos para estudiar el fenómeno, sin que exista hasta el momento un acuerdo sobre lo apropiado de cada uno de éstos. El presente estudio se centra en el análisis de la productividad bibliográfica en torno al término Violencia Doméstica (Domestic Violence), quizás el más arraigado para describir la violencia en la pareja, y ofrece datos sobre años de publicación, país, idioma, sexo de la muestra, grupos de edad, revistas y autores más productivos y la relación víctima-agresor en dichas publicaciones, para finalizar con una reflexión sobre la pertinencia de su uso.Domestic violence: A bibliographic and bibliometric review. Violence among relatives and emotionally linked people has recently made a huge social impact. Professionals have suggested diverse concepts to explain the issue, but they have not yet reached an agreement about these concepts. The present work focuses on the scientific yield associated with the keywords «Domestic Violence», perhaps the most commonly used to refer to violence in romantic couples. A series of related publications is analyzed and data about publication years, countries, languages, sample genders, age groups, most prolific journals and authors, and victim-abuser relationships is provided, along with a reflection upon the correctness of the usage of the keyword

10 Gigabit White Rabbit: sub-nanosecond timing and data distribution

Time synchronization is a critical feature for many scientific facilities and industrial infrastructures. The required performance is progressively increasing everyday, for instance, few tens of nanoseconds for Fifth Generation (5G) networks or sub-nanosecond accuracy on next family of particle accelerators and astrophysics telescopes. Due to this exigent accuracy, many applications require specific timing dedicated networks, increasing the system cost and complexity. Under this context, the new IEEE 1588-2019 High Accuracy (HA) default profile is intensively based on White Rabbit (WR) which can provide sub-nanosecond accurate synchronization for Ethernet networks. However, current WR solutions have not been designed to work properly with high data bandwidth delivery services even in 1 Gigabit Ethernet (GbE) links. On this contribution, the authors propose a new architecture design that enables WR and, consequently, the IEEE 1588-2019 HA profile to be deployed over 10 GbE links solving the already identified data bandwidth problem. Furthermore, this work addresses different experiments needed to characterize the system performance in terms of time synchronization and data transfer. As final result, this contribution presents for the first time in the literature a new WR system which allows high bandwidth data exchange in 10 GbE networks while providing sub-nanosecond accuracy synchronization. The proposed solution maintains the time synchronization performance of existing WR 1 GbE devices with significant advantages in terms of latency and data bandwidth, enabling its deployment in applications that integrate data and synchronization information in the same network.European Union (EU) 725490H2020 ASTERICS 653477AMIGA7 RTI2018-096228-B-C3

Non-esterified fatty acids profiling in rheumatoid arthritis: Associations with clinical features and Th1 response

Since lipid compounds are known to modulate the function of CD4+ T-cells and macrophages, we hypothesize that altered levels of serum non-esterified fatty acids (NEFA) may underlie rheumatoid arthritis (RA) pathogenesis.Serum levels of NEFA (palmitic, stearic, palmitoleic, oleic, linoleic, γ-linoleic, arachidonic -AA-, linolenic, eicosapentaenoic -EPA- and docosahexaenoic -DHA-) were quantified by LC-MS/MS after methyl-tert-butylether (MTBE)-extraction in 124 RA patients and 56 healthy controls (HC). CD4+ phenotype was studied by flow cytometry. TNFα, IL-8, VEGF, GM-CSF, IFNγ, IL-17, CCL2, CXCL10, leptin and resistin serum levels were quantified by immunoassays. The effect of FA on IFNγ production by PBMC was evaluated in vitro.Lower levels of palmitic (p<0.0001), palmitoleic (p = 0.002), oleic (p = 0.010), arachidonic (p = 0.027), EPA (p<0.0001) and DHA (p<0.0001) were found in RA patients, some NEFA being altered at onset. Cluster analysis identified a NEFA profile (hallmarked by increased stearic and decreased EPA and DHA) overrepresented in RA patients compared to HC (p = 0.002), being associated with clinical features (RF, shared epitope and erosions), increased IFNγ expression in CD4+ T-cells (p = 0.002) and a Th1-enriched serum milieu (IFNγ, CCL2 and CXCL10, all p<0.005). In vitro assays demonstrated that imbalanced FA could underlie IFNγ production by CD4+ T-cells. Finally, changes on NEFA levels were associated with clinical response upon TNFα-blockade.An altered NEFA profile can be found in RA patients associated with clinical characteristics of aggressive disease and enhanced Th1 response. These results support the relevance of lipidomic studies in RA and provide a rationale for new therapeutic targets

Low cost ad-hoc sigma-delta analog to digital converters (ΣΔ ADCs) are used to sample the PFC input and output voltage. Instead of being measured, the input current is estimated in a digital circuit to be used in the current loop. A nonlinear carrier control is implemented in the digital controller in order to obtain the power factor correction. Drive signal delays cause differences between the digital current and the real current, producing that volt-seconds error. The control algorithm is compensated taking into account the delays. The influence of a wrong compensation is presented. Experimental results show power factor values and harmonic content within the IEC 61000-3-2 Class C standard in different operation conditions. Furthermore, the use of this PFC stage for electronic ballasts to compensate the effect of the utility voltage fluctuation in HID lamps is also verified taking advantage of the digital device capabilities.This work is sponsored by the Spanish Ministry of Education and Science through the project CICYT-TEC 2008-0175

The Importance of the Participatory Dimension in Urban Resilience Improvement Processes

This article discusses the approach adopted by the researchers into citizen participation in urban regeneration actions and projects. It describes the concepts of sustainability and habitability in relation to the urban environment and architecture within the framework of improving the resilience of our cities through the circular economy and decarbonisation processes in architecture. The authors review the participatory dimension of different urban regeneration actions carried out in Spain and the impact of this dimension on the results obtained by environmental, economic and social urban improvements. They then define possible strategies and methodological tools for integrating this dimension into traditional urban regeneration processes. The article presents case studies and their specific characteristics, and draws conclusions about their effectiveness and relevance. It also compares citizen-led interventions with interventions led by public administrations. Lastly, the authors analyse the potential reasons for success in these processes and projects, identifying weaknesses and proposing possible strategies for future development by researchers

Influence of Physical Education Teachers on Motivation, Embarrassment and the Intention of Being Physically Active During Adolescence

According to a WHO report (2018), more than 80% of adolescents do not do enough physical activity. Physical Education (PE) classes should be aimed at solving this problem. The present study aims to analyze the influence teachers have on motivation, embarrassment and intention to be physically active among their students. A total of 604 secondary school students participated in the study. Various statistical analyses were carried out to explain the causal relationships between the variables. The results revealed a positive relation between the autonomy support and the satisfaction of basic psychological needs (BPN), and a negative relation with the frustration of BPN. In contrast, perceived control revealed a positive relation with frustration of BPN, and a negative relation with the satisfaction of BPN. Satisfaction of BPN was negatively related to embarrassment and positively related to self-determined motivation. On the other hand, frustration of BPN was positively related to embarrassment and negatively with self-determined motivation. Embarrassment was negatively related to self-determined motivation, and the latter was positively related to intention to be physically active. Indeed, the study demonstrates the influence and the importance of PE teachers and of the motivational and emotional processes of adolescents during PE classes and the role they play in acquiring the habits of an active lifestyle
