The proposed concept consists in placing a steel profile with limited size inside the reinforced concrete column of the first level of the building. This profile is not considered for the design and is essen-tially assumed to act as a safety belt activated only in case of deficiencies of the concrete under earthquake action, providing thus the requested robustness and limiting the risk of soft-storey mechanisms even in the most unfavorable conditions. Theoretical, experimental and numerical investigations summarized in the pre-sent contribution are aiming at demonstrating the efficiency of the concept. [less ▲]

This letter proposes a formulation of the corrective security-constrained optimal power-flow problem imposing, in addition to the classical post-contingency constraints, existence and viability constraints on the short-term equilibrium reached just after contingency. The rationale for doing so is discussed and supported by two examples. [less ▲]

Using a full scale anesthesia simulator, we compare and analyze the responses of anesthesia trainees (second and third year trainees and fourth and fifth year trainees) to 4 simulated problem situations that are very close to a real-world situation in order to establish relationship between these analyses and the contents of medical training cursus. Data were collected from systematic observations and videotaping of simulation sessions and self-confrontation. Several quantitative and qualitative variables were used to compare the performance of subjects: accuracy and speed of diagnosis, type of behaviors, identification and selectivity of diagnostic indices, hypotheses generated, type of reasoning.

L'impuissance érectile est souvent considérée comme un symptôme simple et banal. Pourtant, il apparaît très vite que la plus grande incertitude plane sur la nature et l'efficacité des facteurs étiologiques supposés. La méconnaissance de certains facteurs, leur multiplicité, les interactions complexes qui les unissent, l'aspécificité du symptôme ne permettent guère d'aboutir à une conviction raisonnable. Ce problème se pose également sur le plan organique et sur le plan psychique. En fait, il semblerait que chacune des diverses théories explicatives soit adéquate dans des cas particuliers mais qu'aucune ne soit généralisable, contrairement à ce que beaucoup d'auteurs et praticiens font.

This study reports on 100 cases of males, aged 21 to 63 years, consulting for difficulties or inability to perform an intercourse erection with a partner of their choice. Every patient was investigated by the same psychiatrist the same psychologist and the same endocrinologist. Testosterone blood level was found insufficient (2 sigma under the mean) in 48 cases. The psychological tests emphasized an important but clinically inconspicuous psychopathology. Anxious and depressive trends were very frequent. The result of the investigations oriented the treatment, which used several methods, single or in association : brief psychotherapy, nasal stress, hormones, psychotropic drugs. After one year of follow-up, 67 men were improved or recovered and 22 unchanged. [less ▲]

We study the impulsive responses of a grounded linear oscillator coupled to a light nonlinear attachment through an essentially nonlinear (nonlinearizable) stiffness. We analyze the periodic and quasi-periodic dynamics of the undamped system forced by a single impulse on the linear oscillator and being initially at rest, by considering separately low-, moderateand high-energy impulsive motions. The motivation for studying the impulsive dynamics of this system centers on passive targeted energy transfer properties of the corresponding weakly damped one, that is, of the possibility of one-way, irreversible transfer of energy from the linear oscillator to the nonlinear attachment. A rather surprising aspect of this work is the complexity of the analysis required to study the impulsive dynamics of this system, due to its high degeneracy, as it undergoes a co-dimension three bifurcation. 2006 Elsevier B.V.

A comprehensive study of the doping dependence of the phase diagram of FeSe-based superconductors is still required due to the lack of a clean and systematic means of doping control. Here, we report on the magneto-optical imaging, thermodynamic and transport properties, as well as in situ angle-resolved photoemission spectroscopy (ARPES) studies, on the impurity scattering in stoichiometric FeSe single crystals. Co doping at the Fe site is found to decrease the superconducting transition temperature. The upper critical field and specific heat all indicate a possible multiband superconductivity with strong coupling in the Co-doped system. A remarkable feature in FeSe is that its temperature dependent resistivity exhibits a wide hump at high temperatures, a signature of a crossover from a semiconductinglike behavior to metallic behavior. A structural tetragonal-to-orthorhombic phase transition Ts (a consequence of the electronic nematicity) is suppressed by either physical or chemical pressures. Due to the reconstruction of the Fermi surface at Ts, specific heat anomalies at Ts present ΔCp/Ts≈γn, the Sommerfield coefficient at low temperature. This reflects additional electronic instability in the FeSe(1−x)Sx system. ARPES data between 180 and 282 K indicates the existence of a chemical potential shift with increasing thermal excitations, resulting in a change of the Fermi-surface topology and exhibiting a semimetal behavior. We found that the temperature-induced Lifshitz transition is much higher than the temperature for the nematic order. [less ▲]

C’est un truisme d’écrire que dès la réalisation d’une infraction, il appartient à la partie poursuivante de déterminer à qui il revient de « demander compte de la transgression » . Cette opération, d’apparence simple, peut se compliquer lorsque la loi désigne elle-même plusieurs auteurs. Elle exige encore d’appréhender l’étendue de la participation de plusieurs personnes à la commission d’un crime ou d’un délit. L’arrêt, prononcé par la Cour de cassation le 20 janvier 2009 dans une affaire de droit pénal social, est l'occasion pour les auteurs de l'article de faire le point sur des notions élémentaires du droit répressif à savoir l’imputabilité et la complicité.
