Vene õppekeelega põhikooli õpilaste ja õpetajate hoiakud eestikeelse aineõppe suhtes vahetult enne 2007. aasta gümnaasiumireformi algust
2009
Artiklis uuritakse kvantitatiivselt üheksanda klassi õpilaste ja neid eesti keeles õpetanud pedagoogide hoiakuid osalise eestikeelse aineõppe suhtes ning analüüsitakse, millised tegurid soodustavad õpilaste positiivsete hoiakute kujunemist eesti õppekeele suhtes, pöörates erilist tähelepanu uuringus täheldatud erinevusele osa õppeaineid eesti keeles omandanud ja kõiki õppeaineid vene keeles õppinud põhikoolilõpetajate hoiakute vahel. Artikli lõpuosas vaadeldakse kvalitatiivselt eestikeelse aineõppe positiivseid ja negatiivseid mõjusid, näidatakse probleeme, millega eestikeelses aineõppes osalenud õpilased ja õpetajad on kokku puutunud, ning tutvustatakse nende pakutud võimalikke lahendusi. …
Modelos de mundo y violencia en los Comentarios reales del Inca Garcilaso / World’s Models and violence in Inca Garcilaso’s Comentarios reales
2017
A partir de la teoría de los modelos de mundo este trabajo analiza la posición mantenida por el Inca Garcilaso en relación al problema de la subalternidad del indio. Adquiere una especial relevancia la revisión de la cuestión de la enunciación indígena, para lo cual se lleva a cabo un análisis contrastivo entre el Inca Garcilaso y Guaman Poma.Palabras clave: Teoría de los modelos de mundo, Inca Garcilaso, Subalternidad, literatura colonial. Abstract:Taking into account Theory of Wordl’s Model, this essay analyzes the position of Inca Garcilaso in relation to the problema of Indian’s subalternity. It is very important in this text the review of the problem of Indigen’s enunciation, and for t…
Elementos que fundamentan el mito de Hipólito en Eurípides, Séneca y Racine

Los libros de viajes medievales castellanos : Introducción al panorama crítico actual: ¿cuántos libros de viajes medievales castellanos?
1991
Se examinan y estudian algunos de los principales libros de viajes de la literatura castellana medieval, en su contexto europeo, con especial atención al 'Libro del conosçimiento', la 'Embajada a Tamorlán' y el 'Tratado' de Pero Tafur. Se analiza los textos, en su contenido y en su poética de pertenencia a un género híbrido, que combina lo narrativo y descriptivo con lo novelesco, y la voz autobiográfica con la necesidad de objetivación didáctica.
Calibration of high voltages at the ppm level by the difference of $$^{83{\mathrm{m}}}$$ 83m Kr conversion electron lines at the KATRIN experiment
2018
The neutrino mass experiment KATRIN requires a stability of 3 ppm for the retarding potential at − 18.6 kV of the main spectrometer. To monitor the stability, two custom-made ultra-precise high-voltage dividers were developed and built in cooperation with the German national metrology institute Physikalisch-Technische Bundesanstalt (PTB). Until now, regular absolute calibration of the voltage dividers required bringing the equipment to the specialised metrology laboratory. Here we present a new method based on measuring the energy difference of two $$^{83{\mathrm{m}}}$$ 83m Kr conversion electron lines with the KATRIN setup, which was demonstrated during KATRIN’s commissioning measurements …
Electrocardiographic Imaging Using a Spatio-Temporal Basis of Body Surface Potentials—Application to Atrial Ectopic Activity
2018
Electrocardiographic imaging (ECGI) strongly relies on a priori assumptions and additional information to overcome ill-posedness. The major challenge of obtaining good reconstructions consists in finding ways to add information that effectively restricts the solution space without violating properties of the sought solution. In this work, we attempt to address this problem by constructing a spatio-temporal basis of body surface potentials (BSP) from simulations of many focal excitations. Measured BSPs are projected onto this basis and reconstructions are expressed as linear combinations of corresponding transmembrane voltage (TMV) basis vectors. The novel method was applied to simulations o…
Relationship Between the Critical Power Test and a 20-min Functional Threshold Power Test in Cycling.
2021
To investigate the agreement between critical power (CP) and functional threshold power (FTP), 17 trained cyclists and triathletes (mean ± SD: age 31 ± 9 years, body mass 80 ± 10 kg, maximal aerobic power 350 ± 56 W, peak oxygen consumption 51 ± 10 mL⋅min–1⋅kg–1) performed a maximal incremental ramp test, a single-visit CP test and a 20-min time trial (TT) test in randomized order on three different days. CP was determined using a time-trial (TT) protocol of three durations (12, 7, and 3 min) interspersed by 30 min passive rest. FTP was calculated as 95% of 20-min mean power achieved during the TT. Differences between means were examined using magnitude-based inferences and a paired-samples…
External Load Variables Affect Recovery Markers up to 72 h After Semiprofessional Football Matches.
2019
Background: Player tracking devices are commonly used to monitor external load from training and matches in team sports. Yet, how the derived external load variables relate to fatigue and recovery post-training or post-match is scarcely researched. The objective was, therefore, to investigate how external load variables affect recovery markers up to 72 h post-match. Methods: Semiprofessional players from six teams wore tracking devices during three experimental football matches. External load variables including individual playing duration, total distance, PlayerLoad™, high-intensity running, and high-intensity events were derived from the tracking devices, and blood samples and performance…
Physical activity, nutrition, and bone health
2018
This review aims to describe the roles that physical activity and nutrition have in bone metabolism and to examine their effects on bone in a situation of altered metabolism as a consequence of inadequate nutrition and/or excessive physical activity. Referring to the recent studies and the main guidelines in the literature on athlete nutrition, the paper also focuses on essential nutrients for bone health during performance. Finally, it discusses the negative effect of some nutrients on bone mineral density.
El sexo, el contexto familiar y la actividad física extraescolar como factores asociados a la coordinación motriz en la niñez. Un estudio piloto. [Ge…
2019
Existen diversos factores que determinan el desarrollo y la evolución de la coordinación motriz. El presente estudio tiene por objetivo analizar la influencia del sexo, la actividad física practicada por los padres, la existencia de hermanos/as mayores o de igual edad y la práctica de actividad física extraescolar sobre el nivel de coordinación motriz global. La muestra estuvo compuesta por 23 niñas y 32 niños de entre 8-9 años (M = 8,51; DT = 0,31), pertenecientes al tercer curso de Educación Primaria. El nivel de coordinación motriz global de los estudiantes se valoró a través del Test Motor GRAMI-2 (Ruiz, Rioja, Graupera, Palomo, y García, 2015). El análisis de regresión lineal múltiple …
