El error de traducción en la localización de videojuegos: estudio descriptivo y comparativo entre videojuegos indie y no indie
2018
Esta tesis doctoral pertenece al ámbito de la Traductología y, concretamente, se incluye dentro de los estudios sobre la TAV (traducción audiovisual). La investigación que llevamos a cabo consiste en un estudio descriptivo y comparativo sobre la presencia de errores de traducción en videojuegos indie y no indie que han sido traducidos de inglés a español. La localización de videojuegos, etiqueta bajo la cual se recoge la práctica de traducir estos productos, supone un objeto de estudio productivo para abordar un fenómeno omnipresente en todas las modalidades traductoras, como es el de error de traducción, dadas las características intrínsecas de los videojuegos y de los textos que los compo…
Localización de interiores mediante radiofrecuencia: Estudio, análisis y propuestas de mejora
2019
El sistema de posicionamiento global (GPS) es el sistema más utilizado en aplicaciones de localización en exteriores, pero es ineficiente para la localización en interiores. En los últimos años, los sistemas de posicionamiento en interiores se han desarrollado ampliamente. Para ello se han utilizado varias tecnologías inalámbricas, como ZigBee, WLAN y banda ultra ancha (UWB). Los principales métodos de medición de la señal inalámbrica en los sistemas de localización en interiores son el tiempo de llegada (TOA), la diferencia de tiempo de llegada (TDOA), el ángulo de llegada (AOA) y la indicación de intensidad de señal recibida (RSSI). Los sistemas de posicionamiento TOA, TDOA y AOA requiere…
La localización de sujetos adictos en un estudio de seguimiento
2000
El problema de la localización y posterior entrevista de los sujetos seguidos en estu¬dios de carácter longitudinal parece agrandarse cuando se trata de pacientes adictos, siendo frecuente la asociación entre dificultades de localización y evolución terapéuti¬ca más pobre.Los resultados de nuestro estudio, centrado en una muestra de 210 pacientes adictos localizados después de un año y medio del inicio del tratamiento, indican que no siem¬pre las dificultades de localización se asocian a peores resultados; los pacientes que presentan más dificultades para entrevistar no difieren de manera significativa de aque¬llos que resulta más fácil localizar y entrevistar. Así pues, parece que las subm…
Sound conversion phenomena at the free surface of liquid helium. I. Calculation of the coefficients of reflection, transmission, and transformation o…
1980
On the basis of a set of boundary conditions describing quite generally mass and energy transport processes across the free surface of helium II, the acoustic coefficients of reflection, transmission, and transformation of first sound, second sound, and the sound wave propagating in the vapor are calculated in the case of perpendicular incidence of sound waves against the liquid-vapor phase boundary. Considering rigorously the influences of the Onsager surface coefficients, the isobaric thermal expansion coefficients, and the thermal conductivities of the liquid and the vapor, we derive sets of equations from which the acoustic coefficients are determined numerically. For estimations, simpl…
FTIR spectroscopy studies of high pressure-induced changes in pork macromolecular structure
2019
Abstract High pressure processing (HPP) allows to extend the shelf life of meat and meat products by pressurization of microorganisms. At the same time, HPP can induce changes of the protein structure. Vacuum-packed pork chops were HPP-treated at 300, 600 MPa for 1 or 15 min. Samples of raw, cooked and HPP-treated meat muscles and juice were analysed to evaluate the structure of macromolecules. HPP caused visible discolouration of pork chops; hence, the colour of pork meat surface was tested. The lightness (colour component L*) was directly proportional to the applied pressure, probably due to the increased protein denaturation by high pressure. Pork meat muscle and juice samples were analy…
Different pathways for the nuclear import of yeast RNA polymerase II
2015
Recent studies suggest that RNA polymerase II (Pol II) has to be fully assembled before being imported into the nucleus, while other reports indicate a distinct mechanism to import large and small subunits. In yeast, Iwr1 binds to the holoenzyme assembled in the cytoplasm and directs its nuclear entry. However, as IWR1 is not an essential gene, Iwr1-independent pathway(s) for the nuclear import of Pol II must exist. In this paper, we investigate the transport into the nucleus of several large and small Pol II subunits in the mutants of genes involved in Pol II biogenesis. We also analyse subcellular localization in the presence of drugs that can potentially affect Pol II nuclear import. Our…
Contra la patologización intensiva en términos de derechos humanos: Activismo gordo en Argentina
2020
This work addresses the way in which Argentine Fat Activism has developed, in recent years, the demand for depathologization of fatness, taking elements from critical discourses on the health of fat people to frame them in a perspective typical of the Human Rights. First, the contemporary fat body is described in terms of stigma and discrimination, especially in the health field. Then, they refer to a series of critical positions on the pathologization and medicalization of fatness from the biomedical perspective, Fat Studies and Fat Activism. Lastly, a series of interventions that the Argentine activist collective Taller Hacer la Vista Gorda produced between 2017 and 2020 were considered, …
Endometrial gene expression analysis at the time of embryo implantation in women with unexplained infertility
2009
Successful embryo implantation depends on the quality of the embryo, as well as on the receptivity of the endometrium. The aim of this study was to investigate the endometrial gene expression profile in women with unexplained infertility in comparison with fertile controls at the time of embryo implantation in order to find potential predictive markers of uterine receptivity and to identify the molecular mechanisms of infertility. High-density oligonucleotide gene arrays, comprising 44 000 gene targets, were used to define the endometrial gene expression profile in infertile (n = 4) and fertile (n = 5) women during the mid-secretory phase (day LH + 7). Microarray results were validated usin…
Asymmetry in the human primary somatosensory cortex and handedness.
2003
Brain asymmetry is a phenomenon well known for handedness and language specialization and has also been studied in motor cortex. Less is known about hemispheric asymmetries in the somatosensory cortex. In the present study, we systematically investigated the representation of somatosensory function analyzing early subcortical and cortical somatosensory-evoked potentials (SEP) after electrical stimulation of the right and left median nerve. In 16 subjects, we compared thresholds, the peripheral neurogram at Erb point, and, using MRI-based EEG source analysis, the P14 brainstem component as well as N20 and P22, the earliest cortical responses from the primary sensorimotor cortex. Handedness w…
Variability in human hepatic MRP4 expression: influence of cholestasis and genotype
2007
The multidrug resistance protein 4 (MRP4) is an efflux transporter involved in the transport of endogenous substrates and xenobiotics. We measured MRP4 mRNA and protein expression in human livers and found a 38- and 45-fold variability, respectively. We sequenced 2 kb of the 5'-flanking region, all exons and intron/exon boundaries of the MRP4 gene in 95 patients and identified 74 genetic variants including 10 non-synonymous variations, seven of them being located in highly conserved regions. None of the detected polymorphisms was significantly associated with changes in the MRP4 mRNA or protein expression. Immunofluorescence microscopy indicated that none of the non-synonymous variations af…
