Cardiorespiratory Fitness and the Risk of Serious Ventricular Arrhythmias: A Prospective Cohort Study.
2019
Cardiorespiratory fitness (CRF) is an established risk factor for cardiovascular disease outcomes. However, the relationship of CRF with risk of ventricular arrhythmias (VAs) is unknown. We aimed to assess the prospective association of CRF with the risk of serious VAs. Cardiorespiratory fitness, as measured by maximal oxygen uptake, was assessed using a respiratory gas exchange analyzer in 2299 middle-aged men in the Kuopio Ischemic Heart Disease prospective cohort. We corrected for within-person variability in CRF levels using data from repeated measurements 11 years apart. During median follow-up of 25.3 years (interquartile range, 18.7-27.2 years), 73 serious VAs were recorded. The age-…
Perceptions of university students about their education in physics in secondary education
2018
Este artículo presenta los resultados de un cuestionario diagnóstico sobre las percepciones hacia la física, por parte de 104 estudiantes, quienes inician su carrera profesional de Licenciatura en Ciencias Naturales y Educación Ambiental, en una universidad colombiana. Este estudio, se centró en las siguientes categorías: experiencias sobre el aprendizaje de la física, metodología del profesor en la clase de física, dificultades de los estudiantes para aprender física y sugerencias para mejorar su enseñanza. Los resultados reflejan la importancia de explorar y generar estrategias, que permitan optimizar las cuatro dimensiones; por ejemplo, en relación al aprendizaje de la física, los partic…
Aristóteles entre doxografía y biografía: sobre Diógenes Laercio V 31
2019
Se pretende llamar la atención sobre un par de frases que aparecen justo hacia la mitad de la controvertida doxografía de Aristóteles que se puede leer en las Vidas y doctrinas de los filósofos más ilustres de Diógenes Laercio V 31, y que desde luego no corresponden a ningún sistema doxográfico conocido. Como sucede no pocas veces en la obra laerciana, la misma apreciación sobre si el filósofo debe o no enamorarse y contraer matrimonio se repite idéntica en otras doxografías completamente distintas: la cirenaica (DL II 91), la estoica (DL VII 129) y la epicúrea (DL X 118). Cabe plantearse, pues, el origen de este interés, en varias doxografías, por la vida sentimental, podríamos decir, de l…
Applying the RUSLE and ISUM in the Tierra de Barros Vineyards (Extremadura, Spain) to Estimate Soil Mobilisation Rates
2020
Spain is one of the largest wine producers in the world, with Extremadura (south-west Spain) being its second-largest producing region after Castilla La Mancha. Within Extremadura, the most traditional and productive viticulture region is the Tierra de Barros, which boasts an annual production of 3×
Applying health promoting sports club standards in the Netherlands
2014
This study explores health promotion activity of Dutch sports clubs by using the Health Promoting Sports Clubs (HPSC) standards, which are developed in Finland and here applied to the Dutch sports context. The standards consist of 23 items which cover different perspectives on health promotion. The standards form an overall HPSC index, which is used to create health promotion profiles for the sports clubs. 17 sports clubs from the municipality of ‘s-Hertogenbosch participated in this study, of which 42 club officials (1-6 per club) evaluated their own club on all HPSC standards on a five-point Likert scale. Per club, the average score on each standard was calculated. The average on the HPSC…
A Proposal of Process Fragment Definition and Documentation
2012
This paper focuses on the field of Situational Method Engineering (SME) for the construction of agent-oriented design processes. Whatever SME approach a method designer wants to use, he has to manage two main elements: the (method or process) fragment and the repository where it is stored. Specific fragment definition and documentation are fundamental during these activities, for new process composition, and for the consequent system design activities. This paper aims at illustrating a proposal of fragment definition and documentation. This proposal is aimed to be an input for the IEEE FIPA Design Process Documentation and Fragmentation working group and, as regards our own research work, t…
A new set of standards for in–situ measurement of bromine abundances in natural silicate glasses: Application to SR-XRF, LA-ICP-MS and SIMS techniques
2017
Measuring the low bromine abundances in Earth's materials remains an important challenge in order to constrain the geodynamical cycle of this element. Suitable standard materials are therefore required to establish reliable analytical methods to quantify Br abundances. In this study we characterise 21 Br-doped glasses synthesized from natural volcanic rocks of mafic to silicic compositions, in order to produce a new set of standards for Br analyses using various techniques. The nominal Br contents (amounts of Br loaded in the experimental samples) of 15 of 21 glasses were confirmed within 20% by instrumental neutron activation analysis (INAA). Using this new set of standards, we compare thr…
Reliability, validity and performance determinants of the military simulation test for the assessment of anaerobic performance in soldiers
2020
Introduction: Measurements of physical fitness have been identified as one of the most important research priorities in the military. Currently, the physical fitness tests of The Finnish Defence Forces (FDF) do not include a valid and reliable anaerobic test. In order to develop job-related task simulation tests, the purpose of the study was to determine the reliability and validity of a high-intensity military simulation test (MST), which is designed to assess the task-specific anaerobic performance of soldiers. The MST includes typical combat-related maneuvers while wearing a 20 kg combat load. Methods: 22 male cadets (22.5 ± 0.8 years) volunteered to participate. The MST was performed th…
Comparison of the Richardson and BCS models of superconductivity based on calculations of ground state energies
2017
Suprajohtavuuden Richardsonin ja BCS mallien vertailu perustilojen laskettujen energioiden perusteella. Suprajohtavuus on edelleen aktiivinen tutkimuksen alue, koska sen tarjoamista mahdollisuuksista huolimatta sitä ei vielä ymmärretä kokonaisvaltaisesti. Tässä pro gradu -tutkielmassa käyn läpi perusteet kahdelle suprajohtavuuden mallille, Richardsonin ja BCS malleille. BCS teoria on ensimmäinen ja käytetyin mikroskooppinen suprajohtavuuden teoria. Richardsonin malli on harvemmin käytetty malli, josta saadaan redusoidun BCS Hamiltonin operaattorin tarkat ominaistilat. Lasken molempien mallien perustilojen energiat sekä redusoidulle että täydelle BCS Hamiltonin operaattorille. Sama lasketaan…
Employees’ adherence to information security policies: An exploratory field study
2014
The key threat to information security comes from employees who do not comply with information security policies. We developed a new multi-theory based model that explained employees' adherence to security policies. The paradigm combines elements from the Protection Motivation Theory, the Theory of Reasoned Action, and the Cognitive Evaluation Theory. We validated the model by using a sample of 669 responses from four corporations in Finland. The SEM-based results showed that perceived severity of potential information security threats, employees' belief as to whether they can apply and adhere to information security policies, perceived vulnerability to potential security threats, employees…
