Monte Carlo Simulation of Irradiance Distribution on the Retina After Refractive Surgery
Authors: Canales Vidal F , Cagigal Manuel P
Published: December 2019

ABSTRACT

PURPOSE: Generation of random wavefronts for ocular wave aberration statistics across the population has been used for various analyses. We propose a more accurate simulation procedure. This simulation technique is not intended to be a perfect representation of an eye, but instead is a tool for those applications where a correct distribution of aberrations across a population is necessary.

METHODS: Our technique consists of the generation of coefficients of the wavefront expansion into Zernike modes. The simulation makes use of the variance of every mode measured on a large population by using compact and reliable wavefront sensors.

RESULTS: The simulation procedure was verified by reproducing two statistical functions that characterize eye behavior. This tool can be used to predict the performance of sensing techniques and to evaluate the consequences of customized ophthalmic elements and refractive surgery. It may also be useful for deriving both first and second order photon statistics of the point-spread function on the human retina (a key parameter in certain visual perception models).

CONCLUSIONS: A new tool for analysis of customized refractive surgery is presented and the evolution of the light intensity probability density function on the retina with compensation attained after customized correction of the eye's aberrations is analyzed. [J Refract Surg 2004;20:384-390]
The Importance of the Phase Transfer Function to Visual Function and Visual Quality Metrics
Authors: Sarver Edwin J , Applegate Raymond A
Published: December 2019

ABSTRACT

PURPOSE: To propose a vision quality metric that directly incorporates the phase transfer function.

METHODS: The process of retinal image formation from the pupil to the retina is presented to identify possible domains for calculating vision quality metrics. These domains are pupil plane metrics using ocular aberrations, and retinal plane metrics using the point spread function or optical transfer function. The importance of the phase transfer function to visual performance is demonstrated and a method is proposed for directly including phase in a vision quality metric based on ocular wavefront error.

RESULTS: A family of vision quality metrics is proposed, which directly incorporates the StilesCrawford effect, contrast sensitivity function, and the phase transfer function.

CONCLUSION: The phase transfer function is an important aspect of the quality of an image, and it may be directly included in metrics intended to quantify vision quality. [J Refract Surg 2004;20:S504-S507]
Quantifying Scatter in Shack-Hartmann Images to Evaluate Nuclear Cataract
Authors: Donnelly William J , Pesudovs Konrad , Marsack Jason D , Sarver Edwin J , Applegate Raymond A
Published: December 2019

ABSTRACT

PURPOSE: Quantify and localize lenticular forward scatter using Shack-Hartmann wavefront sensing (SHWS) as single-valued metrics and a scatter map, and to examine the relationships between forward scatter and backscatter metrics and visual acuity.

METHODS: We obtained SHWS images from 148 patients in the Texas Investigation of Cataract Optics study. Patient age was 22 to 84 years, with Lens Opacities Classification System III (LOCS III) nuclear opalescence (NO) scores ranging from 0.8 to 5.6. Visual acuities were measured at photopic (280 cd/mp 2) high (VA^sub PHC^) and low contrast (VA^sub PLC^) and mesopic (0.75 cd/mp 2) high (VA^sub MHC^) and low contrast (VA^sub MLC^). Scattering was described in a scatter map and by five single-valued metrics characterizing SHWS lens let point spread functions. The relationships between scatter and visual acuity were tested using linear regression.

RESULTS: Visual acuities decreased proportional to both LOCS III NO (Rp 2=up to 39%) and scatter metrics (Rp 2=up to 21%). Stepwise multiple linear regression improved visual acuity prediction by including a backscatter and a forward scatter metric (Rp 2 up to 51.2%). For the subjects over age 60 years (N=46, 68.8?6.12 years), the forward scatter metrics explain as much variance in visual acuities (Rp 2=up to 29%) as LOCS III NO (Rp 2=up to 26%). Combined they accounted for up to 48.8% of visual acuity variance.

CONCLUSION: Forward light scatter can be quantified using SHWS and the resulting metrics explain significant variance in visual acuity, especially in the aging eye. Together with a backscatter metric they explain approximately 50% of the variance in VA. [J Refract Surg 2004;20:S515-S522]
Advantages and Disadvantages of the Zernike Expansion for Representing Wave Aberration of the Normal and Aberrated Eye
Authors: Klyce Stephen D , Karon Michael D , Smolek Michael K
Published: December 2019

ABSTRACT

PURPOSE: Zernike expansion has been selected for use in describing wavefront aberrations in the human eye. The advantages and limitations of this approach are assessed for eyes with varying degrees of aberration.

METHODS: Corneal topography examinations were taken with the Nidek OPD-Scan topographer/aberrometer. These higher data density corneal topography examinations were converted to height data and subsequently to wavefront representations. System noise was evaluated with a 2D frequency analysis of 43-D test balls. Both Zernike polynomials and 2D Fourier transforms were used to evaluate fidelity in the presentation of the point spread function. A display format for potential clinical use was developed based upon Zernike decomposition.

RESULTS: Systematic noise from the corneal topographer was found to be minimal and, when eliminated, produced small changes in the point spread function. Using Zernike decomposition up to the 30th order failed to preserve the higher frequency aberrations present in aberrated eyes. Use of a Zernike decomposition display with a fixed micron scale presented only clinically significant details of spherical aberration, coma, trefoil, irregular components above third order and total higher-order aberrations (above second order).

CONCLUSIONS: Zernike polynomials excel in extracting the low-order optical characteristics of visual optics. Zernikes accurately represent both low- and high-order aberrations in normal eyes where high-order aberrations are clinically insignificant. For eyes after corneal surgery or eyes with corneal pathology such as keratoconus that have significant higher-order aberrations, the Zernike method fails to capture all clinically significant higher-order aberrations.

Authors: Vinciguerra Paolo , Camesasca Fabrizio I
Published: December 2019

ABSTRACT

PURPOSE: Treatment of highly aberrated eyes with opacities or irregularities consequent to previous refractive treatment, ulcers, keratitis, trauma, or corneal dystrophies remains a challenge for refractive surgeons. We evaluated the results of custom phototherapeutic keratectomy (CPK) with intraoperative corneal topography -based aberrometry and custom ablation in highly aberrated eyes.

METHODS: We prospectively evaluated eyes undergoing custom phototherapeutic keratectomy (CPK) with custom ablation for corneal opacities and/or irregularities due to previous refractive treatment, keratitis, trauma, or dystrophies. Customization was planned according to corneal topography-based aberrometry, performed intraoperatively after removal of corneal epithelium.

RESULTS: We treated 35 eyes of 34 patients. Mean preoperative haze was 1.6 ? 1.4 in eyes with previous refractive surgery. Mean preoperative pachymetry was 425.7 ? 119.3 ???. Mean preoperative spherical equivalent refraction was -1.60 ? 3.65 D ranging from -9.38 to +10.00 D. No eye reached 20/15 best spectaclecorrected visual acuity (BSCVA), and only 63% could see 20/30 BSCVA. At final 6 -month examination, mean spherical equivalent refraction was -0.71 ? 4.01 D, ranging from -11.25 to +5.25 D. All eyes reached 20/30 or better BSCVA, and 19% had 20/15 or better BSCVA.

CONCLUSIONS: Intraoperative, epithelium-free topography-based corneal aberrometry proved to be a feasible option for custom ablation in highly aberrated eyes. This approach widens the applications of PTK, providing a new procedure, custom PTK, that can be a successful solution for eyes that would otherwise require penetrating keratoplasty.

Corneal Thickness and Elevation Maps Computed From Optical Rotary Scans
Authors: Franco Sandra , Almeida José B , Parafita Manuel
Published: December 2019

ABSTRACT

PURPOSE: Recently, the authors presented a technique that allows corneal thickness measurements along any meridian from optical sections obtained using a rotary scanning system. This paper presents three-dimensional mapping of the corneal thickness and topography of both corneal surfaces, obtained with the rotary system.

METHOD: Corneal thickness and topography are computed from optical sections obtained by illumination with a collimated beam expanded in a fan by a small cylindrical lens. This lens is provided with motor driven rotation to perform automated rotary scanning of the whole cornea. Two cameras are used to capture the images of the optical sections.

RESULTS: With this system, it is possible to obtain measurements of corneal thickness, as well as corneal topography. Corneal thickness and elevation maps are shown.

CONCLUSIONS: Although still under development, this new optical system allows measurement of the thickness of the whole cornea as well as topographical mapping of both corneal surfaces. [J Refract Surg 2004;20:S576-S580]
The Theoretical Effect of Measured Wavefront Diameter on Estimating Peripheral Wavefront Data
Authors: Steinert Roger
Published: December 2019

ABSTRACT

PURPOSE: To compare the difference between wavefront data measured in the periphery and that calculated from estimations using a smaller measured region.

METHODS: A total of 32 eyes were measured using the Alcon LADARWave aberrometer (Alcon Laboratories Ine, Fort Worth, Tex). Aberrations were measured through a dilated pupil to the 6th order at a 6.5-mm diameter. Data were then "clipped" to 5.0, 5.5, and 6.0 mm, and each of these smaller diameter wavefronts was used to estimate the larger diameter wavefront coefficients. The measure of interest was the mean and range of error between the estimated and measured values, and how they varied for the different diameters of known data.

RESULTS: The differences in both the mean and range of error were inversely correlated to the diameter of the region of known data. As this region grew smaller, the region estimated grew larger, with resultant larger mean errors. At 5 mm, the estimated zone was an annulus of 0.75-mm width; in this case the estimated higher order aberrations were 60% higher than those measured, with a range of 40% lower to 300% higher. At 5.5 mm and 6.0 mm, these differences were much smaller, but statistically significant. The differences were greatest when significant peripheral aberrations were measured, as can occur with post-laser in situ keratomileusis eyes.

CONCLUSION: Basing a treatment on an estimation of the peripheral wavefront may lead to an inaccurate ablation profile. The inaccuracy increases as the size of the measured wavefront decreases relative to the planned ablation zone. The inaccuracy is also greatest when significant peripheral aberrations are present. Refractive surgery systems should only treat optical zones that are smaller than or equal to the diameter of the measured wavefront. [J Refract Surg 2004;20:S627-S630]
Expanded Range CustomCornea Algorithms for Myopia and Astigmatism: One-month Results
Authors: Carones Francesco , Vigo Luca , Scandola Elena , Sorace Sergio G
Published: December 2019

ABSTRACT

PURPOSE: To evaluate the early clinical results achieved with an algorithm adjusted for an expanded range of correction in wavefront-guided customized ablation with the LADARVision4000 (Alcon Laboratories Ine, Fort Worth, Tex).

METHODS: Fifty-five consecutive eyes from 31 patients underwent wavefront-guided, customablation laser in situ keratomileusis (LASIK) (Hansatome and BD 4000 microkeratomes, LADARWave aberrometer, LADARVision4000 laser system). These were normal myopic and astigmatic eyes that had never been operated on. The spherical equivalent refractive error was +0.30 to -8.13 diopters (D) (mean -4.26 ± 2.14 D) and the astigmatism ranged from 0 to -3.75 D (mean -0.97 ± 0.96 D). All eyes were treated according to the CustomCornea protocol using the commercial LADARVision4000 platform. Patients were followed for at least 2 months and standard visual measurements were taken and recorded at 1 day and 1, 3, and 6 months after treatment. The results of treatment were assessed using the following parameters: uncorrected visual acuity (UCVA) and best spectacle-corrected visual acuity (BSCVA); manifest spherical equivalent refractive error; wavefront measurement of high order aberrations; and subjective reports of visual symptoms by patients.

RESULTS: One month after LASIK, the mean manifest spherical equivalent refractive error was -0.18 ± 0.41 D. Seventy-eight percent and 96% of eyes had manifest spherical equivalent refractive error within ±0.50 D and ±1.00 D of attempted correction, respectively, with 78% of eyes with 20/20 or better UCVA. Eyes with 20/16 and 20/12.5 BSCVA were 89% and 36%, respectively (55% and 7% preoperatively). The mean high order aberrations rootmean-square was 0.34 ± 0.10 µ?? preoperatively and 0.35 ± 0.09 µ?? postoperatively (6.0-mm pupil size). High order aberrations were either reduced, unchanged, or increased by <10% in 58% of eyes. Subjectively, patients reported no visual symptoms and had no complaints regarding the quality of their vision.

CONCLUSION: The new optimized algorithm for higher refractive errors appears to be effective in improving BSCVA, and a minority of patients demonstrated an increase in the magnitude of high order aberrations when compared to preoperative aberrometry. A slight spherical equivalent refraction undercorrection will be addressed with future nomogram adjustments. [J Refract Surg 2004;20:S649-S653]
La meloterapia en el pensamiento y la obra de Isidoro de Sevilla
Authors: Diago Jiménez José María
Published: December 2019

Isidoro de Sevilla (ca. 565-633), Padre y Doctor de la Iglesia, es considerado uno de los más grandes enciclopedistas de la Antigüedad tardía y la Alta Edad Media. Entre los muchos temas que trató se encuentra la música y, dentro de esta, el poder medicinal o sanador de la misma, temática que gozó de una gran tradición literaria en la Antigüedad clásica debido, en gran parte, a la difusión de sus profundas raíces filosófico-musicales, fundamentalmente de índole pitagórica y platónica. En este artículo se localizan y analizan por primera vez todas las reflexiones isidorianas sobre este tema distribuidas por varias obras del obispo hispalense. Para ello se partirá de la tradición clásica y patrística de la que proceden, teniendo en cuenta también el resto del pensamiento musical isidoriano.

El suelo industrial como factor de oportunidad y resiliencia en espacios mineros y rurales de León (España)
Authors: Benito del Pozo Paz , Diez Vizcaíno Francisco José
Published: December 2019

Se plantea analizar con un enfoque de geografía económica y método hipotético-deductivo el alcance de la estrategia pública de promoción de áreas empresariales en tres ámbitos comarcales de la provincia de León de dominancia rural y/o minera: Órbigo, Montaña y El Bierzo, considerando los desafíos de la crisis desencadenada en 2008 y la importancia del suelo industrial en la resiliencia de estos espacios. La hipótesis es que la oferta de suelo empresarial es un factor de resiliencia capaz de mejorar la capacidad de respuesta de espacios en declive y zonas rurales, ya que sería inductor de tres efectos positivos: reforzar la ventaja competitiva del territorio en coyunturas post-crisis, impulsar la innovación mediante proyectos empresariales de nuevo cuño, y mejorar las expectativas de progreso local. Los resultados obtenidos mediante técnicas cualitativas, uso de estadísticas y cartografía confirman la premisa de partida, pero también desvelan que los efectos positivos de los polígonos industriales y parques empresariales pueden ser de baja intensidad y producirse a ritmo desigual.
La humanización del espacio público: el corazón urbano como lugar de expresión de la sociedad moderna
Authors: Cachorro Fernández Emilio
Published: December 2019

Los centros urbanos siempre han desempeñado un decisivo papel impulsor de la vida comunitaria, en cuanto que lugares físicos reconocibles donde se intensifica socialmente la confluencia, aunque con fluctuaciones en modo e intensidad según la época. El desarrollo industrial provocó la desarticulación de las ciudades debido a su crecimiento desenfrenado, relegando a la mayoría de la población al extrarradio, con el riesgo de perder sus valores tradicionales como colectividad por culpa de una excesiva disgregación. Un gradual proceso que alertó de la necesidad de nuevos modelos capaces de recuperar la cohesión social, más aún tras la coyuntura de reconstrucción suscitada en la segunda posguerra mundial. Por esta razón, se aborda el estudio del “corazón de la ciudad” durante el último siglo, con el fin de profundizar en la diferente consideración de que ha sido objeto en cada período, a partir de una serie de precedentes que nos sitúan en los albores de la modernidad, cuando fueron surgiendo diferentes posicionamientos ideológicos que se han ido ampliando y revisando con el paso de las décadas y que, seleccionados por su relevancia y confrontados para un mejor análisis, claman en favor de restablecer la integración tomando como base los espacios de encuentro y relación.

Authors: Fernández Cacho Silvia
Published: December 2019

En este artículo se analiza la influencia que han producido en la gestión del patrimonio cultural los avances técnicos, científicos y operativos en materia de paisaje durante los últimos veinte años a través de su incorporación a la legislación sectorial de las distintas comunidades autónomas. Para ello se plantean tres ámbitos de convergencia entre patrimonio y paisaje (conceptual, material y simbólico) y su reflejo en la normativa vigente a través de los distintos instrumentos de gestión que se incorporan en cada caso. Se concluye que se están realizando avances metodológicos y prácticos en la integración de la dimensión paisajística en la gestión patrimonial, aunque se constatan también importantes carencias que abren nuevas posibilidades y retos de futuro.
Uso del fuego y régimen de incendios en la provincia de Cáceres. Conclusiones a partir de los datos del Interrogatorio de la Real Audiencia de Extremadura (1790)
Authors: Montiel Molina Cristina , Galiana Martín Luis
Published: December 2019

El objetivo del artículo es caracterizar y evaluar la presencia del fuego como instrumento de gestión del territorio, señalando las continuidades y cambios en su uso desde finales del siglo XVIII hasta mediados del siglo XX. A partir de la situación descrita en el Interrogatorio de la Real Audiencia de Extremadura de 1790, se realiza un análisis evolutivo del uso del fuego en la provincia de Cáceres mediante la información suministrada por fuentes judiciales y policiales depositadas en el Archivo Histórico Provincial (AHP). Se maneja además el Registro Histórico de Incendios Forestales (RHIF) creado por el grupo de investigación Complutense, que se remonta al año 1497 y cuenta con casi 7.000 registros de incendios históricos datados y documentados. Todo ello ha permitido profundizar en el conocimiento sobre la distribución espacio temporal del fuego útil, su relación con la organización del terrazgo y los conflictos que generaba, suministrando interesantes conclusiones sobre la intensa relación existente entre su uso en el marco de los sistemas agrarios tradicionales y el posterior régimen de incendios que se instala acompañando la crisis de dicho sistema de organización.
Debates políticos y religiosos: la magnanimidad aristotélica en el Demócrates primero de Juan Ginés de Sepúlveda
Authors: Díez Yáñez María
Published: December 2019

El Democrates. De conuenientia militiae cum Christiana religione dialogus de Juan Ginés de Sepúlveda, traducido al castellano por Antonio Barba, cuenta entre sus fuentes principales con la Ética de Aristóteles. En este trabajo analizo, por un lado, el desarrollo que presenta este diálogo de la virtud de la magnanimidad y su compatibilización con dos virtudes esencialmente cristianas: la humildad y la pobreza. Por otro lado, se señala la relación que puede establecerse entre el contenido de este Diálogo y las acusaciones que recibió Sepúlveda a propósito de sus Comentarios a la Ética aristotélica. Ambas cuestiones funcionan como reflejo de ciertos rasgos morales y religiosos que contribuyen a la configuración del hombre moderno.
El Tractado de la vida de Christo: sobre prohibiciones «hagiográficas» del Índice de Fernando de Valdés (1559)
Authors: Arronis Llopis Carme
Published: December 2019

El Tractado de la vida de Christo es una de las consideradas vidas devocionales prohibidas por el Índice de censura de Fernando de Valdés de 1559, interdicción que nunca ha sido convenientemente analizada. En general, el veto a este tipo de lectura, que a priori no atenta contra la ortodoxia del culto católico, ha sido poco atendido, y mucho menos cuando se trata de vidas devocionales —o hagiográficas, en sentido amplio—, cuya prohibición parece ser resultado del más minucioso y sutil intento por definir los límites de la ortodoxia católica y controlar la devoción privada. Analizaré los aspectos conflictivos que presenta el texto, que en la mayoría de los casos dependen, más que del contenido estricto del tratado, de los elementos paratextuales, de los posibles usos que se atribuían al volumen o de su origen y difusión, y que probablemente se estimaron problemáticos como consecuencia de la coyuntura histórica en que se examinaron.
Sin dios, rey ni ley. Excesos, crítica y reforma de la inquisición en la defensa de Macanaz a la Historia civil de España, de Belando
Authors: Precioso Izquierdo Francisco
Published: December 2019

A mediados de 1744 la Inquisición estrechaba el cerco sobre la Historia Civil de España, obra de fray Nicolás de Jesús Belando. La identificación del autor con las posiciones más regalistas encarnadas por el polémico ex fiscal general del Consejo de Castilla, Melchor Macanaz, y las críticas al tribunal por su proceder durante el bienio reformista de 1713-1715, rebasaba con creces lo tolerado por las autoridades del Santo Oficio. En este artículo profundizamos en la interpretación que mereció para Macanaz el proceso inquisitorial de Belando, una oportunidad que le permitió insistir en la idea de una Inquisición subordinada al rey y dependiente de su jurisdicción como medio único de adecuación de la institución al Estado real absoluto.

Decadencia e intentos de reforma de la música eclesiástica española en el siglo XIX
Authors: Capdepón Verdú Paulino
Published: December 2019

Este artículo se centra en la decadencia que experimentó la música eclesiástica española desde comienzos del siglo XIX coincidiendo con el estallido de la Guerra de la Independencia. Dicha decadencia se agravó a consecuencia de la aplicación de las sucesivas desamortizaciones por los distintos gobiernos liberales y de la firma del concordato de 1851. Para remediar tal situación se propusieron distintos proyectos de reforma e iniciativas por parte de autores como Eslava, Barbieri, Pedrell u Olmeda, con el objetivo final de revitalizar la música religiosa de España y las capillas musicales que la sustentaban: tales proyectos, que adquirieron notable impulso gracias al movimiento cecilianista, constituyen el prolegómeno de la promulgación del Motu Proprio por el Papa Pío X en 1903.

Lee wave detection over the Mediterranean Sea using the Advanced Infra-Red WAter Vapour Estimator (AIRWAVE) total column water vapour (TCWV) dataset
Authors: Papandrea Enzo , Casadio Stefano , Castelli Elisa , Dinelli Bianca Maria , Miglietta Mario Marcello
Published: December 2019

Abstract. Atmospheric gravity waves generated downstream by orography in a stratified airflow are known as lee waves. In the present study, such mesoscale patterns have been detected, over water and in clear-sky conditions, using the Advanced Infra-Red WAter Vapour Estimator (AIRWAVE) total column water vapour (TCWV) dataset, which contains about 20 years of day and night products, obtained from the thermal infrared measurements of the Along Track Scanning Radiometer (ATSR) instrument series. The high accuracy of such data, along with the native 1 km×1 km spatial resolution, allows the investigation of small-scale features such as lee waves. In this work, we focused on the Mediterranean Sea, the largest semi-enclosed basin on the Earth. The peculiarities of this area, which is characterised by complex orography and rough coastlines, lead to the development of these structures over both land and sea. We developed an automatic tool for the rapid detection of areas with high probability of lee wave occurrence, exploiting the TCWV variability in spatial regions with a 0.15∘×0.15∘ area. Through this analysis, several occurrences of structures connected with lee waves have been observed. The waves are detected in spring, autumn and summer seasons, with TCWV values usually falling in the range of 15 to 35 kg m−2. In this article, we describe some cases over the central (Italy) and the Eastern Mediterranean Basin (Greece, Turkey and Cyprus). We compared a case of perturbed AIRWAVE TCWV fields due to lee waves occurring over the Tyrrhenian Sea on 18 July 1997 with the sea surface winds from the synthetic aperture radar (SAR), which sounded the same geographical area, finding a good agreement. Another case has been investigated in detail: on 2 August 2002 the Aegean Sea region was almost simultaneously sounded by both the second sensor of the ATSR series (ATSR-2) and the Advanced ATSR (AATSR) instruments. The AIRWAVE TCWV fields derived from the two sensors were successfully compared with the vertically integrated water vapour content simulated with the Weather Research and Forecasting (WRF) numerical model for the same time period, confirming our findings. Wave parameters such as amplitude, wavelength and phase are described through the use of the Morlet continuous wavelet transformation (CWT). The performed analysis derived typical wavelengths from 6 to 8 km and amplitudes of up to 20 kg m−2.
Changing characteristics of runoff and freshwater export from watersheds draining northern Alaska

Published: December 2019

Abstract. The quantity and quality of river discharge in Arctic regions is influenced by many processes including climate, watershed attributes and, increasingly, hydrological cycle intensification and permafrost thaw. We used a hydrological model to quantify baseline conditions and investigate the changing character of hydrological elements for Arctic watersheds between Utqiagvik (formerly known as Barrow)) and just west of Mackenzie River over the period 1981–2010. A synthesis of measurements and model simulations shows that the region exports 31.9 km3 yr−1 of freshwater via river discharge, with 55.5 % (17.7 km3 yr−1) coming collectively from the Colville, Kuparuk, and Sagavanirktok rivers. The simulations point to significant (p<0.05) increases (134 %–212 % of average) in cold season discharge (CSD) for several large North Slope rivers including the Colville and Kuparuk, and for the region as a whole. A significant increase in the proportion of subsurface runoff to total runoff is noted for the region and for 24 of the 42 study basins, with the change most prevalent across the northern foothills of the Brooks Range. Relatively large increases in simulated active-layer thickness (ALT) suggest a physical connection between warming climate, permafrost degradation, and increasing subsurface flow to streams and rivers. A decline in terrestrial water storage (TWS) is attributed to losses in soil ice that outweigh gains in soil liquid water storage. Over the 30-year period, the timing of peak spring (freshet) discharge shifts earlier by 4.5 d, though the time trend is only marginally (p=0.1) significant. These changing characteristics of Arctic rivers have important implications for water, carbon, and nutrient cycling in coastal environments.

La evaluación de herramientas como modo de aprendizaje e introducción de las Humanidades Digitales en el aula universitaria. La experiencia docente “Poesía distante”
Authors: Martínez Cantón Clara I. , Ruiz Fabo Pablo
Published: December 2019

Las tecnologías y su dimensión ubicua se hacen presentes en todas las disciplinas y han cambiado la forma de estudiar e investigar, creando campos como las Humanidades Digitales cuyo auge es ya innegable. Los estudios de grado en humanidades no siempre reflejan este giro digital. En este artículo presentamos los resultados de una experiencia docente cuyo objetivo ha sido la mejora de la adquisición de los contenidos de métrica en poesía del grado, así como la adquisición de contenidos transversales en relación a la tecnología y la digitalidad. Para ello se ha combinado la enseñanza de la métrica española con la de las tecnologías computacionales que se aplican a su análisis desde las Humanidades Digitales, buscando una implicación directa de los estudiantes en la investigación universitaria. Con ese fin se organizó una actividad que planeó videoconferencias con expertos internacionales y a una actividad de anotación métrica de sonetos para su procesado computacional. Los resultados, obtenidos por medio de una encuesta de satisfacción y las calificaciones de los estudiantes, muestran una clara mejora en los resultados de la asignatura para los que participaron en esta experiencia y una alta satisfacción con los contenidos referentes a tecnología y la digitalidad aprendidos. Ciertos aspectos como el tamaño de la muestra o la necesidad de otros datos comparativos quedan para la discusión de esta experiencia.
'Quijote' y fraseología: una propuesta para la enseñanza del español
Authors: González Cobas Jacinto
Published: December 2019

En los últimos años se ha abierto cierto debate en torno al uso de textos literarios en las clases de ELE, olvidados en gran parte en los primeros años del Enfoque comunicativo. Ello ha impedido el aprovechamiento didáctico de no pocas obras literarias, forma de actuación de la que no ha escapado el Quijote. Este artículo se inscribe en un marco en el que se considera que la literatura puede hacer interesantes aportaciones en el proceso de enseñanza/aprendizaje de idiomas. El Quijote genera curiosidad entre los aprendientes, permite la imbricación de la competencia lingüística y sociocultural, y constituye una importante muestra de unidades fraseológicas construidas con verbos de movimiento. En esta investigación se hacen algunas consideraciones sobre la presencia de la literatura en el aula de ELE, sobre el Quijote y la fraseología contenida en él, al tiempo que se presenta una propuesta didáctica (una caza del tesoro) para llevar al aula de ELE la figura de Cervantes, el Quijote y parte de la fraseología empleada en esta obra.

Published: December 2019

Esta propuesta de intervención educativa nace de la importancia de promover el aprendizaje de la lengua en el ámbito escolar, con el objetivo de poner a disposición del estudiante aquellos recursos que permiten la comunicación. Con esta finalidad, se ha elaborado una secuencia didáctica que incide sobre dos vertientes principales: la comprensión lectora y la expresión escrita. Las actividades se confeccionan a partir de las microhabilidades formuladas por Cassany, Luna y Sanz (2005), para la mejora de la comprensión lectora y a través de las pautas de Camps (2003), en el caso de la composición escrita. Los resultados revelan la importancia de emplear métodos didácticos diversos que mejoren en los educandos su capacidad de comprensión y de composición de textos escritos, habilidades inherentemente relacionadas. Finalmente, se pone de manifiesto la utilidad de la secuencia didáctica después de su implementación en el aula.
Jean-Baptiste Del Amo: Bloodhound and animalist
Authors: Ibeas-Atlamira Juan Manuel , Vázquez Lydia
Published: December 2019

The purpose of this paper is to study the 18th century’s sources of Une éducation libertine by Jean-Baptiste Del Amo. This immersive novel showcases a young man initiation story as a rake’s progress. Our transartistic and transtextual approach will allow us to explain the Del Amo storyworld and founts. We focus, in particular, on the daily life in Paris in 1760 (Paris, professions, money, food, cafés, theaters…), in some clichés of the 18th century (justice, sexuality, religion, ‘libertinage’…), the symbolic world of Del Amo and his onomastic exploration. We expose this approach in order to prove that this novel is a tribute to the 18th century but also to evidence that is a masterpiece of the 21th century.

Background: Sleep disorders and fatigue in students may affect emotional intelligence, which is associated with increased risk of cognitive and mental disorders. The aim of this study was to determine sleep quality, fatigue, emotional intelligence, and related factors in Iranian medical students. Methods: This cross-sectional research was conducted in 2016. A total of 400 students were randomly selected from Semnan University of Medical Sciences. Data collection tools included questionnaires for demographic information, the Pittsburgh Sleep Quality Index, and Bradbury-Graves's Emotional Intelligence Inventory and Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF). Results: The quality of sleep was unsatisfactory for 38.5% students, 86.2% did not have general fatigue, and 13.8% were suffering from low overall fatigue. Moreover, 6% displayed low, 24% normal, and 70% high emotional intelligence. Emotional intelligence showed a positive correlation with sleep quality (p = 0.044) and a negative correlation with general fatigue (p = 0.018). Sleep quality showed a negative correlation with general fatigue (p < 0.001). Conclusion: This study demonstrated a significant relationship between sleep quality and fatigue with emotional intelligence and a significant relationship between sleep quality and fatigue.

There are many studies on austenitic stainless steels with transformation induced plasticity (TRIP). Basically, in these steels, there is a significant increase in strength and toughness with the transformation of austenite to martensite. 304L steel finds extensive application in industry. Studies relating to martensitic transformation with plastic deformation are quite common. Many studies involve monotonic loading relating to the martensite formed. In practice, 304L steels are subject to distinct types of loading and possibly with stress concentrators. Thus, also in smaller quantities, it is possible to find in the literature studies involving cyclic loading with the TRIP effect. To contribute to the literature on the analysis of the TRIP effect on these steels, 304L steel samples with stress concentrators underwent interrupted monotonic tensile tests. Optical microscopy (OM) and x-ray diffraction (XRD) technique characterized the martensitic transformation. Other 304L steel samples with a stress concentrator underwent a low cycle fatigue test. The martensitic transformation, in this case, was possible to follow with the electron backscatter diffraction technique (EBSD). The samples after the interrupted monotonic tests show a high martensite volume fraction formed 1mm away from the notch (30% to 50%), due to the plastic deformation suffered. From 5.5mm of the notch, the samples again display a microstructure like that of the as-received (AR) sample. For the low cycle fatigue tested sample, the high concentration of deformation-induced martensite was within 15mm of the discontinuity. Approximately 0.5mm from the circular discontinuity, the sample again has a microstructure like the initial sample (IS).
