L'objectif de ce travail est de se réapproprier la contribution de Heinrich Rickert au programme critique de fondation de l'ontologie. Il est apparu que cette contribution résidait dans l'analyse des structures formelles du jugement et, plus exactement, dans l'analyse du jugement existentiel. À la suite de Rickert, il a fallu déployer cette analyse sur deux versants: le versant noétique ou la théorie des actes judicatifs (Der Gegenstand der Erkenntnis, 1892-1928) et le versant noématique ou la théorie des propositions - ou "teneurs" - judicatives (Die Logik des Prädikats und das Problem der Ontologie, 1930). J'ai montré que cette double analyse permet non seulement de dégager deux concepts formels de l'être (l'être comme "Jaform" et comme "Urprädikat"), mais aussi de jeter les bases d'une théorie des catégories embrassant à la fois les étants sensibles et les étants non sensibles.

Experimental branching fractions for laser lines arising from excited states of 5d97s configuration of Au II have been determined by application of Laser Induced Breakdown Spectroscopy (LIBS). The experimental relative transition probabilities were converted into an absolute scale using theoretical values for the radiative lifetimes of the corresponding states, calculated in this work. Transition probabilities and radiative lifetimes have been determined by a relativistic Hartree - Fock method taking configuration interaction and core-polarization effects into account. A comparison of the present results with the available theoretical values has been made and shows a reasonable agreement although discrepancies are observed between theory and experiment for some transitions.

Cet article inséré dans un manuel universitaire mexicain cherchant à dresser un bilan de la situation de la géographie humaine aujourd'hui se veut une réflexion générale de ce qu’est et devrait être l’enseignement de la géographie au niveau du secondaire et ce au départ de près de 30 ans de recherche en didactique de la géographie. Cette réflexion s’articule autour de quatre questions fondamentales : quels objectifs ? quelles acquisitions de base ? comment enseigner ? comment évaluer les acquis ? [less ▲]

Clownfishes live in social group within sea anemones. They are prolific “singers” that produce a wide variety of sounds, described as “pops” and “chirps”, involved in both reproductive and agonistic interactions. Although clownfish sounds were recorded since 1930, the mechanism of sound production has remained unresolved. <br />The sounds used to describe the sonic mechanism were directed towards hetero- and conspecifics that approach their sea anemone host. Sound recordings were synchronized using a high speed video (500 fps) coupled or not with an X-ray system. These systems allowed to quantify the movements of external and internal bones during sound production. Sounds were typically accompanied by rapid (< 30 ms) head movements such as elevation of the skull, lowering of the hyoid bar and the anterior part of the branchial basket, retraction of the pectoral girdle, and finally closing of the mouth. Synchronization of sound pulses with X-ray images indicates that sound is produced when the hyoid apparatus is completely lowered and the mouth closed by a previously unknown mechanism. <br />Dissections of freshly dead specimens reveal an unusual ligament responsible for the rapid mouth closing. This ligament joins the hyoid bar to the internal part of the mandible. Acting as a cord, it forces the mandible to turn around its articulation during the lowering of the anterior part of the branchial basket, forcing the mouth to close. Sounds result from the collision of the jaw teeth, transferring energy to the jaws that are presumably the sound radiator. [less ▲]

We investigate experimentally and theoretically the superconducting properties of an Al thin film covering a periodic array of Co/Pt magnetic disks with out-of-plane magnetization for different radii of the magnetic disks and constant period of the magnetic lattice. The presence of the arrays of magnetic dots leads to a quantized displacement of the normal/superconducting phase boundary along the magnetic field axis, with each step corresponding to a flux-quantum per unit cell of the magnetic lattice. We demonstrate that this so-called field-induced superconductivity is strongly dependent not only on the chosen magnetic material and its magnetization M but also on the radius R of the constructed magnetic disks. Since field-induced superconductivity is directly linked to the nucleation of vortex-antivortex (V-AV) pairs, a theoretical M-R equilibrium phase boundary is presented, delimiting regions of different numbers of induced V-AV pairs per magnet. A good qualitative and quantitative agreement is found between theory and experiment. [less ▲]

The familial occurrence of pituitary adenomas has been recognized for many years and currently accounts for approximately 5% of all cases. Molecular, genetic and clinical features of familial pituitary adenomas have been well characterized in multiple endocrine neoplasia type 1 (MEN-1) and Carney's complex (CNC), which account for the majority of familial pituitary tumor cases. These conditions are caused by MEN1 and PRKAR1A gene mutations, respectively, and the clinical and pathological features of pituitary pathology in these diseases differ from those of sporadic pituitary tumors. Familial acromegaly has been recognized for many years and, more recently, the clinical features of this clinical phenotype, referred to as isolated familial somatotropinoma, have been clarified. Over the past decade, the concept of non-MEN-1/CNC familial pituitary tumors has been expanded significantly to include all phenotypes, a condition known as familial isolated pituitary adenomas (FIPA). In FIPA, tumors can present homogeneously (same phenotype) or heterogeneously (different tumor phenotypes) within the same family. Compared with sporadic pituitary adenomas, patients with FIPA have a younger age at diagnosis and have larger tumors. The clinical features of FIPA differ from those of MEN-1 in terms of a higher frequency of somatotropinomas and a lower frequency of prolactinomas. The recent discovery of the involvement of mutations in the aryl hydrocarbon receptor interacting protein (AIP) gene in association with pituitary tumors has provided new information regarding potential mechanisms of tumorigenesis in FIPA patients. While very infrequent in sporadic pituitary tumors, approximately 15% of FIPA patients have AIP mutations, rising to half of patients with familial acromegaly. In this review, we detail the clinical features of FIPA and discuss tumor pathology and genetic findings in this increasingly recognized clinical condition. [less ▲]

La présente contribution se penche sur l’évolution actuelle de la stratégie latino-américaine de l’Union européenne et plus particulièrement sur le nouveau « partenariat stratégique » scellé par cette dernière, en juillet 2007, avec le Brésil. Pourquoi, après tant d’années d’efforts à construire des relations de groupe à groupe régional avec le MERCOSUR, Bruxelles s’intéresse dorénavant à développer des relations directes et régulières avec Brasilia ? La réponse à la question est pluricausale. Au-delà des déterminants liés au système international post-11 septembre et aux aspirations européennes de reconnaissance internationale dans un monde davantage stato-centré, l’initiative communautaire s’explique également par les mutations auxquelles fait face la scène politique latino-américaine et par la volonté de l’Union d’adapter sa stratégie à ces changements.
