Henry Perowne y su realismo clínico : Variaciones sobre medicina y literatura en Sábado, de Ian McEwan

La tendencia a ver las cosas desde el punto de vista de la propia profesión, en lugar de tener una perspectiva más amplia, implica que la formación profesional a menudo resulte en una distorsión en la forma en que se percibe el mundo. En el caso de los médicos, estos tiene la función de "producir la verdad" acerca de la enfermedad y la salud, de modo que detentan un poder omnímodo. En Sábado, de Ian McEwan, vemos cómo la formación profesional puede tener una enorme influencia en la personalidad y cómo se puede hacer uso y abuso del poder que confiere ser médico. El Dr. Henry Perowne, protagonista de la novela, es incapaz de dejar el guardapolvo colgado cuando está fuera del hospital, lo que implica que su visión del mundo y sus relaciones interpersonales estén teñidas por una mirada médica que le impide interpretar a las situaciones y las personas que lo rodean desde un punto de vista más global y humano. Esta incapacidad para apartarse de su "realismo clínico" es también lo que entorpece su acercamiento a la literatura: estar siempre aferrado al mundo fáctico representa un obstáculo para apreciar y disfrutar de la ficción y la poesía

Una identificación poética : Jaime Gil de Biedma lee Juan de Mairena, de Antonio Machado

"Puestos a escoger entre nuestras concepciones poéticas y la fidelidad a la propia experiencia, finalmente optamos por esta última". Esa frase de Jaime Gil de Biedma bien podría formar parte de uno de los aforismos del libro Juan de Mairena, de Antonio Machado. La problemática de la conformidad de lo ético junto a lo estético nos lleva a la propuesta de ese artículo, es decir, el análisis del importante papel de la obra Juan de Mairena para la afirmación de una posición ético-poética en la obra de Jaime Gil

Total V9 rDNA information organized at the OTU level

The present data set provides a tab separated text file compressed in a zip archive. The file includes metadata for each TaraOceans V9 rDNA OTU including the following fields: md5sum = identifier of the representative (most abundant) sequence of the swarm; cid = identifier of the OTU; totab = total abundance of barcodes in this OTU; TARA_xxx = number of occurrences of barcodes in this OTU in each of the 334 samples;rtotab = total abundance of the representative barcode; pid = percentage identity of the representative barcode to the closest reference sequence from V9_PR2; lineage = taxonomic path assigned to the representative barcode ; refs = best hit reference sequence(s) with respect to the representative barcode ; taxogroup = high-taxonomic level assignation of the representative barcode. The file also includes three categories of functional annotations: (1) Chloroplast: yes, presence of permanent chloroplast; no, absence of permanent chloroplast ; NA, undetermined. (2) Symbiont (small partner): parasite, the species is a parasite; commensal, the species is a commensal; mutualist, the species is a mutualist symbiont, most often a microalgal taxon involved in photosymbiosis; no the species is not involved in a symbiosis as small partner; NA, undetermined. (3) Symbiont (host): photo, the host species relies on a mutualistic microalgal photosymbiont to survive (obligatory photosymbiosis); photo_falc, same as photo, but facultative relationship; photo_klep, the host species maintains chloroplasts from microalgal prey(s) to survive; photo_klep_falc, same as photo_klep, but facultative; Nfix, the host species must interact with a mutualistic symbiont providing N2 fixation to survive; Nfix_falc, same as Nfix, but facultative; no, the species is not involved in any mutualistic symbioses; NA, undetermined.

Environmental context of selected samples from the Tara Oceans Expedition (2009-2013)

The present data set provides contextual environmental data for samples from the Tara Oceans Expedition (2009-2013) that were selected for publication in a special issue of the SCIENCE journal (see related references below). The data set provides calculated averages of mesaurements made at the sampling location and depth, calculated averages from climatologies (AMODIS, VGPM) and satellite products.

Predicting bed form roughness: the influence of lee side angle

Flow transverse bedforms (ripples and dunes) are ubiquitous in rivers and coastal seas. Local hydrodynamics and transport conditions depend on the size and geometry of these bedforms, as they constitute roughness elements at the bed. Bedform influence on flow energy must be considered for the understanding of flow dynamics, and in the development and application of numerical models. Common estimations or predictors of form roughness (friction factors) are based mostly on data of steep bedforms (with angle-of-repose lee slopes), and described by highly simplified bedform dimensions (heights and lengths). However, natural bedforms often are not steep, and differ in form and hydraulic effect relative to idealised bedforms. Based on systematic numerical model experiments, this study shows how the hydraulic effect of bedforms depends on the flow structure behind bedforms, which is determined by the bedform lee side angle, aspect ratio and relative height. Simulations reveal that flow separation behind bedform crests and, thus, a hydraulic effect is induced at lee side angles steeper than 11 to 18° depending on relative height, and that a fully developed flow separation zone exists only over bedforms with a lee side angle steeper than 24°. Furthermore, the hydraulic effect of bedforms with varying lee side angle is evaluated and a reduction function to common friction factors is proposed. A function is also developed for the Nikuradse roughness (k s), and a new equation is proposed which directly relates k s to bedform relative height, aspect ratio and lee side angle.
