Metabolic Consequences after Urinary Diversion
2014
Metabolic disturbances are well-known, but sometimes neglected immediate consequences or late sequelae following urinary diversion (UD) using bowel segments. Whereas subclinical disturbances appear to be quite common, clinically relevant metabolic complications, however, are rare. Exclusion of bowel segments for UD results in loss of absorptive surface for its physiological function. Previous studies demonstrated that at least some of the absorbtive and secreting properties of the bowel are preserved when exposed to urine.For each bowel segment typical consequences and complications have been reported. The use of ileal and/or colonic segments may result in hyperchloremic metabolic acidosis …
Deep fluid transfer evidenced by surface deformation during the 2014–2015 unrest at Piton de la Fournaise volcano
2016
International audience; Identifying the onset of volcano unrest and providing an unequivocal identification of volcano reawakening remain challenging problems in volcanology. At Piton de la Fournaise, renewal of eruptive activity in 2014–2015, after 41 months of quiescence and deflation, was associated with long-term continuous edifice inflation measured by GNSS. Inflation started on June 9, 2014, and its rate progressively increased through 2015. Inflation onset was rapidly followed by an eruption on June 20–21, 2014, showing that volcano reactivation can be extremely fast, even after long non-eruptive phases. This short-lived eruption involved a shallow source (1.3–1.9 km depth below the …
Geochemical investigations applied to active fault detection in a volcanic area: the North-East Rift on Mt. Etna (Sicily, Italy)
1999
Geochemical investigations were performed on the Northeast Rift of Mt. Etna, a prominent volcanic structure of this volcano. Low-temperature fumaroles were found on the upper part of this area and the isotopic compositions of C(CO2) and He suggest a likely magmatic origin of the emitted gases. On the contrary, very low degassing was found in the lower part of the NE-Rift, with CO2 concentrations generally very close to those in air. This pattern is probably due to sealing of the eruptive fissures by the repeated injections of magma solidified into dikes and by consequent shallow hydrothermal alteration of the fissured rocks due to residual magma degassing. High soil CO2 concentrations were …
Emploi public, emploi privé : la difficile conversion des titulaies de thèse
1998
International audience; Les titulaires de thèse continuent de bénéficier d'une insertion relativement favorable. La plupart deviennent enseignants, chercheurs ou ingénieurs après 3 ans de vie active. Pourtant, leur nombre a fortement augmenté depuis 1989, comme celui de l'ensemble des sortants de l'enseignement supérieur. Ceux qui ne peuvent prétendre à un poste dans l'enseignement supérieur ou la recherche doivent réorienter leur projet professionnel pour espérer se faire une place dans le secteur privé. Ils sont toutefois concurrencés par les diplômés des écoles d'ingénieurs lors de leur recrutement en entreprise. Les docteurs doivent alors tirer profit de leur spécialisation et des liens…
Rough Set Algebras as Description Domains
2009
Study of the so called knowledge ordering of rough sets was initiated by V.W. Marek and M. Truszczynski at the end of 90-ies. Under this ordering, the rough sets of a fixed approximation space form a domain in which every set ↓ is a Boolean algebra. In the paper, an additional operation inversion on rough set domains is introduced and an abstract axiomatic description of obtained algebras of rough set is given. It is shown that the resulting class of algebras is essentially different from those traditional in rough set theory: it is not definable, for instance, in the class of regular double Stone algebras, and conversely.
A new Euler–Mahonian constructive bijection
2011
AbstractUsing generating functions, MacMahon proved in 1916 the remarkable fact that the major index has the same distribution as the inversion number for multiset permutations, and in 1968 Foata gave a constructive bijection proving MacMahon’s result. Since then, many refinements have been derived, consisting of adding new constraints or new statistics.Here we give a new simple constructive bijection between the set of permutations with a given number of inversions and those with a given major index. We introduce a new statistic, mix, related to the Lehmer code, and using our new bijection we show that the bistatistic (mix,INV) is Euler–Mahonian. Finally, we introduce the McMahon code for …
More on the Dimensionality of the GHQ-12: Competitive Confirmatory Models
2019
The General Health Questionnaire (GHQ) was designed to measure minor psychiatric morbidity by assessing normal ‘healthy’ functioning and the appearance of new, distressing symptoms. Among its versions, the 12-item is one of the most used. GHQ-12’s validity and reliability have been extensively tested in samples from different populations. In the Spanish version, studies have come to different conclusions, of one, two, and three-factor structures. This research aims to present additional evidence on the factorial validity of the Spanish version of the GHQ-12, using competitive confirmatory models. Three samples of workers (N= 525, 414 and 540) were used to test a set of substantive models pr…
The implication of subcortical motor centers in voluntary human activities
2009
The main objective of the present dissertation was to analyse the subcortical implications in the preparation and execution of complex voluntary movements. Three different tasks were selected on purpose. They all are everyday activities which although functionally related have differential characteristics. The first task was the sit-to-stand manoeuvre. Simple ballistic movements are executed faster in reaction time task paradigms when the imperative signal is accompanied by a startling auditory stimulus (SAS). We examined whether this effect also occurs in complex movements such as the sit-to-stand manoeuvre, taking into account both anticipatory postural adjustments and prime movers. React…
Valoración de las capacidades físicas y cognitivas en corredores de orientación de la categoría hombres-élite.
2004
El deporte de orientación consiste en realizar un recorrido en el menor tiempo posible y con la única ayuda de un mapa y una brújula, teniendo la particularidad de que cada corredor puede elegir la ruta de desplazamiento de un control a otro. Esto propicia que nos encontremos ante un deporte en el que los aspectos perceptivo-cognitivos van a ser fundamentales.El objetivo de este estudio fue caracterizar a la población española de la categoría hombres-élite, que es la máxima categoría a nivel nacional, con el fin de poder crear pautas de entrenamiento adecuadas.Para ello, realizamos una comparativa entre los corredores de élite (total: 23 corredores) y los participantes del resto de categorí…
Estudio de los trinquetes de pilota valenciana. según criterios epidemiológicos, de opinión y biomecánicos
2010
INTRODUCCIÓN La pilota valenciana es un deporte tradicional muy arraigado en la Comunidad Valenciana cuyas modalidades, escala i corda y raspall se practican en un trinquete. Sin embargo, se ha observado una problemática en los trinquetes actuales: abandono, ausencia de estudios de mejora y carencia de una normativa que establezca las características biomecánicas de los trinquetes, como resultado de la interacción entre el jugador y la pelota con el pavimento. Por otra parte, no se han encontrado investigaciones epidemiológicas en la literatura científica sobre pilota valenciana, ni estudios que relacionen la amortiguación y la fricción con la epidemiología y/o con la mejora del rendimiento…
