Ergonomie des documents techniques informatisés : expériences et recommandations sur l'utilisation des organisateurs para-linguistiques
1998
Despite an increasing development, the design of computerized documents is still based on intuitive or esthetics concerns, rather than on experimental evidence. However a large body of literature has investigated the effects of various display factors, both on a perceptual and on a cognitive level. We propose here a review of research and its implication on the design of computerized documents.
Orbitotomía supero medial: nuevos límites en el abordaje endonasal expandido transetmoidal
2015
Introducción: Los límites de los abordajes endonasales endoscópicos expandidos (AEEE) no están delimitados y continúan en constante evolución. El límite de la extensión lateral en el plano coronal del AEEE transetmoidal descrito hasta el momento viene determinado por la unión del techo de las fóveas etmoidales con la lámina papirácea. Objetivos: Este trabajo se basa en la hipótesis fundamental de que la resección de lesiones situadas en la base craneal anterior, concretamente en la porción formada por el hueso frontal y asentadas más allá de las láminas papiráceas, pueden ser abordadas de forma completamente endonasal endoscópica. La hipótesis operativa considera que es posible mediante la …
Euripides’Andromache, a Choral Tragedy
2013
Andrómaca es una tragedia coral por diversas razones: por el papel tan singular que el coro desempeña en ella desde el comienzo mismo; y porque en ella, a través de dos mujeres enfrentadas, Andrómaca y Hermíone, convergen en la trama dramática una serie de parejas/tríos que marcan el discurrir de unas sagas épico-dramáticas de gran rendimiento en la tradición cultural y literaria griega. Es también una tragedia coral porque en ella se alcanza el destino fi nal de las dos partes implicadas en la mayor guerra mítica de la Antigüedad. Andromache is a choral tragedy because the singular role of the chorus in the whole play and because in its plot there is a group of couples/trios, which lead th…
Reconstitución de la inmunidad celular T frente a citomegalovirus y control de la viremia en el paciente receptor de trasplante alogénico de precurso…
2015
Durante los últimos años la incidencia de la enfermedad orgánica causada por el Citomegalovirus (EOC) en los pacientes receptores de un trasplante alogénico de células precursoras hemotopoyéticas ha disminuido por el uso profiláctico o anticipado del ganciclovir e, indirectamente, el advenimiento de procedimientos muy sensibles para detectar la presencia del CMV en la sangre periférica (viremia): la PCR y la prueba de la antigenemia pp65 (AG). Aun así, la EOC continúa siendo una causa demasiado frecuente de morbididad y mortalidad en estos pacientes. Además, la administración profiláctica generalizada de ganciclovir predispone al paciente a sufrir infecciones bacterianas y fúngicas graves d…

Shell morphology of the unionid mussels (Anodonta anatina, Unio pictorum and U. tumidus) in relation to gender and trematode parasitism
2015
Freshwater mussels (Unionoida) show great variability in shell morphology which can be associated with differences in habitat, sex and/or parasite infection. Three unionid mussel species, (Anodonta anatina, Unio pictorum and Unio tumidus) were collected from two sites Lake Saravesi, (Laukaa) and Lake Kuivasjarvi, (Oulu), between May - October 2012. Intraspecific trends that were associated with the mussels’ sex and/or parasites infection were studied and observations were made on how sex and parasite infection could have a role in shells morphological characters/patterns. The study revealed a range of morphometric differences among and across populations, as well as, within and between spec…
Black Queen Evolution and Trophic Interactions Determine Plasmid Survival after the Disruption of the Conjugation Network
2018
Bacterial antibiotic resistance is often a part of mobile genetic elements that move from one bacterium to another. By interfering with the horizontal movement and the maintenance of these elements, it is possible to remove the resistance from the population. Here, we show that a so-called plasmid-dependent bacteriophage causes the initially resistant bacterial population to become susceptible to antibiotics. However, this effect is efficiently countered when the system also contains a predator that feeds on bacteria. Moreover, when the environment contains antibiotics, the survival of resistance is dependent on the resistance mechanism. When bacteria can help their contemporaries to degrad…
The identity of the tropical African Polichne mukonja Griffini, 1908 (Orthoptera, Tettigoniidae, Phaneropterinae)
2016
Polichne mukonja Griffini, 1908 from Cameroon was hitherto known only from the holotype preserved at the Royal Belgian Institute of Natural Sciences, Brussels. This was probably due to the fact that the genus Polichne Stål, 1874 distributed only in Australia and Papua New Guinea. In view of this distribution, the tropical African species was therefore overlooked in the African literature. The recent discovery of two specimens at the Naturhistorisches Museum, Vienna, now provides us with a better understanding of the identity of this taxon, which is related to the African genus Catoptropteryx Karsch, 1890. Polichne mukonja is here transferred to a new genus Griffinipteryx and both taxa are p…
Global CHIRPS MCWD (Maximum Cumulative Water Deficit) Dataset
2021
Global CHIRPS MCWD Dataset The MCWD (Maximum Cumulative Water Deficit) is a measure of drought severity, which corresponds to the maximum value of the monthly accumulated water deficit reached for each pixel within the year. The MCWD is a useful indicator of meteorologically induced water stress without taking into account local soil conditions and plant adaptations, which are poorly understood in Amazonia. The full method of MCWD is described in Aragão et al. (2007; https://doi.org/10.1029/2006GL028946). Detail about CHIRPS (Rainfall Estimates from Rain Gauge and Satellite Observations) can be found in Funk et al. (2015; https://doi.org/10.1038/sdata.2015.66). Coverage: Spanning 5…
The legacy of human use in Amazonian palm communities along environmental and accessibility gradients
2023
Aim: Palms are iconic and dominant elements of neotropical forests. In the Amazon region, palms have been used and managed by humans for food, material, medicine and other purposes for millennia. It is, however, debated to what extent the structure of modern palm communities reflects long-term human modification. Here, we investigate the complex interplay of ecological and societal factors that influence the distributions of both human-used and non-used palms in western Amazonia. Location: Amazonia. Time period: Present. Major taxa studied: Palms (Arecaceae). Methods: We used Bayesian hierarchical joint species distribution models to predict the distributions and environmental niche dimensi…
