Responses to eccentric rotation in two space-bound subjects
1993
Two subjects were rotated eccentrically in the manner described previously. In contrast to a normal control group, settings of a luminous line to the subjective vertical were almost unrelated to the gravitoinertial vector before, and totally so shortly after, space flight. Only 3 days postflight did a clear relation to the gravitoinertial vector re-establish itself in the one subject who actually flew. The correspondence became normal 5 days after the flight. Since there were no clinical abnormalities evident in the subjects, it is suggested that both subjects suppressed their vestibular information, presumably as an effect of vestibular deconditioning training before the flight. In additio…
Vides kvalitātes novērtējums Cēsu un Priekuļu novada sporta centros
2018
Bakalaura darbā raksturots iekštelpu mikroklimats, bioloģiskais piesārņojums, veikta trokšņa līmeņa izvērtēšana un CO2 koncentrācijas līmeņa novērtēšanas daudzums sporta centru telpās. Sporta centru izmantošanas popularitāte aizvien aug, jo neatkarīgi no gadalaika, diennakts laika un indivīda sagatavotības līmeņa, tie ir pieejami praktiski jebkurā laikā. Novērtējums veikts izmantojot mērījumu metodes, apskatītas un analizētas diennakts un sezonālās parametru svārstības, to ietekmējošie faktori, t.sk. apmeklētāju plūsma. Darba izstrādei izvēlēti sporta centri Cēsīs un Priekuļu novadā. Bakalaura darbs sastāv no 3 nodaļām ar 17 apakšnodaļām, darba tekstuālo daļu papildina 9 tabulas, 31 attēls …
Eccentric fixation measurements using visuoscopy and Macula Integrity Tester (MIT) in children with amblyopia
2021
The aim of the work was to compare measurements of eccentric fixation in children with amblyopia using two different methods, a traditional visuoscopy and MIT. Monocular fixation was evaluated using visuoscopy and MIT in 16 patients (from 5 to 9 years old). Measurements were started with the better seeing eye to compare the results obtained with the amblyopic eye. All study participants were selected with anisometropic and refractive amblyopia. Visuoscopy is simpler than MIT and less dependent on patient responses, so visioscopy can be used for young children who have not yet acquired verbal skills. Children over the age of 5 can more easily understand the MIT method and get more reliable r…
Assessment of spatial perception for a multi-layer volumetric display: the effect of exocentric and egocentric distance on relative depth judgements
2020
Three-dimensional images on multiple depth layers of the volumetric display provide the physiological depth cues which ensure the high precision of depth judgements at close viewing distances and enhance the user experience. However, the contribution of physiological cues declines with an increase of viewing distance (egocentric distance), and the human spatial perception varies depending on the inter-stimuli distance (exocentric distance). We conducted a psychophysical experiment to test the perception of three-dimensional images rendered on the volumetric display depending on exocentric and egocentric stimuli distance. The constant angular size visual stimuli were displayed on different d…
Effets d'une complémentation nutritionnelle en vitamines et minéraux sur la chute de force et les marqueurs biologiques consécutifs à un exercice exc…
2007
Purpose. – The effects of vitamins and minerals complex supplementation on maximal voluntary contraction decrease (FMV) and biological markers following an eccentric exercise at old people. Method. – Sixteen elderly subjects took either placebo (Pl group) or vitamins and minerals (Isoxan Senior, NHS, Rungis, France) (group S) for 21 d before an eccentric exercise and for 3 d after the exercise. The FMV and surface EMG activity (RMS) of the vastus lateralis (VL), vastus medialis (VM) and rectus femoris (RF) were recorded before (Pre), immediately after (Post), 24 h (Post 24) and 48 h (Post 48) after the exercise. CCVThe creatine kinase (CK), lactate deshydrogenase, malondialdehyde, and tumor…
Studi di fonetica greca
2018
Il presente volume contiene tutti i contributi sulla fonetica greca pubblicati dall'autore dall'inizio della sua carriera (1995) ad oggi. Gli argomenti principali: i modelli di produzione della voce e del linguaggio nella Grecia antica da Ippocrate, ad Aristotele, a Galeno. Omero come origine della linguistica e della scienza greca. La terminologia di voce e voce articolata in Omero e i suoi rapporti con le classificazioni fonetiche successive. Le teorie della voce e del suono in Aristotele, anche in relazione alle voci animali. I principi di classificazione fonetica nella Grecia antica, 'elemento' e 'sillaba' dalle origini a Platone e Aristotele e nella tradizione successiva, la teoria del…
Controlling ground-state rotational dynamics of molecules by shaped femtosecond laser pulses
2004
We report controlled excitation of ground-state rotational wave packet by pulse-shaping technique. The experiment is conducted in nitrogen $({\mathrm{N}}_{2})$ at room temperature and atmospheric pressure. A femtosecond laser pulse produces rotational coherences in the vibronic ground state of ${\mathrm{N}}_{2}$ through an impulsive Raman process. The laser pulse is tailored using a spatial light modulator producing spectral phase modulation. Periodic phase steps are applied in order to control the excitation of specific rotational Raman transitions. The outcome is the modification of the relative excitation between odd and even rotational states which allows the control of the symmetry and…
Experiencia y verdad en la hermenéutica de Gadamer. Algunos problemas
2006
Gadamer vincula su concepción de la experiencia hermenéutica a una interpretación especulativa de la verdad que no se justifica simplemente por la exigencia de superar el enfoque metódico. Este ensayo responde al propósito de indagar hasta qué punto esta interpretación sólo supera la escisión fenomenológica entre conciencia y objeto en tanto que remite a un fundamento ontológico de su unidad, que pasa a ocupar la posición de sujeto. Nuestra hipótesis es que el concepto gadameriano de la verdad como una «infinitud de sentido» genera tensiones con su concepción de la experiencia hermenéutica, que permanecen irresueltas. También intentaremos mostrar que una de las consecuencias que se siguen d…

Discussing Eurocentric evaluative epistemic hegemony: an exploratory approach
2017
En el presente artículo pretendo, de una forma aún exploratoria, reunir algunos presupuestos de las teorías poscoloniales/descoloniales para elaborar un pensamiento crítico sobre la hegemonía de determinadas políticas, procesos e instrumentos de evaluación (o de medición educativa), que son claramente eurocéntricos (o euroamericanos) y que integran la actual agenda educativa global. Sin pretender contribuir para subsanar cualquier posible laguna pero reconociendo que, a pesar de las conocidas excepciones, el campo de las políticas de evaluación se encuentra relativamente saturado por abordajes repetitivos y previsibles, me resulta llamativa la capacidad hermenéutica de los presupuestos posc…
