    photoinduced complex between Cu(TMpy-P4) and water molecules, reversibly axially coordinated to the central metal, was observed in picosecond transient absorption and nanosecond resonance Raman experiments. This complex is rapidly created (τ1 = 15 ± 5 ps) in the excited triplet (π, π*) state of Cu-porphyrin, and the subsequent relaxation is proposed to proceed via two parallel pathways. One is fast and efficient (≥90% of molecules), and presumably involves a (π, d) charge-transfer state. The second pathway is slow (τ2 >> 1 ns), has a low quantum yield (≤10%) and involves the excited (d, d) state which is responsible for transient Raman features at ≈ 1553 cm−1 (ν2*) and ≈ 1347 cm−1 (ν4*), and for low-intensity long-lived transient absorption features

    El trabajo que se presenta pretende valorar, mediante los juegos populares, los efectos de un programa de actividad física en la salud física y psicosocial del alumnado de Educación Primaria. La investigación contó con una muestra de 89 escolares de entre 6 y 12 años (M = 8.76; DT = 1.62). Para la recogida de información se utilizó un cuestionario Ad Hoc de 18 ítems que mide 5 dimensiones relacionadas con la salud psicosocial: disfrute, competencia, autonomía, motivación y relación con los demás. Igualmente, las mediciones del peso y talla, el índice de masa corporal (IMC) y las pruebas de condición física centradas en la flexibilidad, velocidad, resistencia y fuerza, permitieron valorar la salud física. Los resultados mostraron una mejora altamente significativa del peso, talla, IMC y condición física del alumnado con independencia del género. Por lo que se concluyó que la práctica habitual de juegos populares beneficia la salud física del alumnado de Educación Primaria. Así mismo, la mejora recogida en todas las variables psicosociales, permite concluir afirmando que los juegos populares fomentan en los escolares de 6-12 años el disfrute, la motivación intrínseca, la competencia, la autonomía y la relación con los demás.The present project’s main objective is to assess the effects of a physical activity program through popular games on physical, mental and social health in Primary School students. The research was carried out with a sample of 89 students aged 6 to 12 years old. An Ad-Hoc questionnaire with 18 items was applied to collect information. The instrument measures 5 dimensions related to mental and social health: enjoyment, competence, autonomy, motivation, and relationships with others. Similarly, measurements of weight and height, the body mass index (BMI), and physical fitness tests focused on flexibility, speed, resistance, and strength, allowed the assessment of physical health. The results showed a high significant improvement of weight, height, BMI and physical fitness of students regardless of gender. Therefore, it may be concluded that regular practice of popular games benefits physical health of Primary School students. Likewise, the improvement in all psychosocial variables leads to the conclusion that popular games promoted students’ enjoyment, intrinsic motivation, feelings of competence, autonomy, and relationship with others

    Spinal Cord Stimulation in the 21st Century — Reviewing Innovation in Neuromodulation

    INTRODUCTION Low back pain (LBP) is a pervasive problem impacting health systems across the world. In the United States, chronic LBP impacts up to 40% of Americans and results in excessive financial strain on the healthcare budget, estimated at up to $100 billion annually.1 Furthermore, treatment results are often disappointing, with the traditional pathway of conservative measures, narcotic pain medication, and surgical decompression and/or fusion leading to both patient and provider frustration, complications, and diminished patient productivity and quality of life. This has naturally led to questions from policymakers regarding the utility of healthcare dollars spent on back pain. In this milieu, a variety of neuromodulation techniques have found a niche in the management of this patient population, with indications commonly quoted including failed back surgery syndrome (FBSS), chronic neuropathic pain, and complex regional pain syndrome (CRPS), among others.1,2 From its inception on the basis of Melzak and Wall’s gate theory³, to its first human trial in the 1960s,⁴ and to the modern era, spinal cord stimulation has undergone a series of innovations that have expanded indications and improved patient outcomes. The goal of this study is to summarize the most important clinical trials involving both traditional SCS and newer stimulation paradigms to provide an overview of the current state of affairs of this rapidly-growing field

    Best practices for Core Argo floats - part 1: getting started and data considerations

    Get PDF
    Argo floats have been deployed in the global ocean for over 20 years. The Core mission of the Argo program (Core Argo) has contributed well over 2 million profiles of salinity and temperature of the upper 2000 m of the water column for a variety of operational and scientific applications. Core Argo floats have evolved such that the program currently consists of more than eight types of Core Argo float, some of which belong to second or third generation developments, three unique satellite communication systems (Argos, Iridium and Beidou) and two types of Conductivity, Temperature and Depth (CTD) sensor systems (Seabird and RBR). This, together with a well-established data management system, delayed mode data quality control, FAIR and open data access, make the program a very successful ocean observing network. Here we present Part 1 of the Best Practices for Core Argo floats in terms of how users can get started in the program, recommended metadata parameters and the data management system. The objective is to encourage new and developing scientists, research teams and institutions to contribute to the OneArgo Program, specifically to the Core Argo mission. Only by leveraging sustained contributions from current Core Argo float groups with new and emerging Argo teams and users who are eager to get involved and are actively encouraged to do so, can the OneArgo initiative be realized. This paper presents a list of best practices to get started in the program, set up the recommended metadata, implement the data management system with the aim to encourage new scientists, countries and research teams to contribute to the OneArgo Program
