L'holographie numérique en infrarouge lointain, utilisant un laser CO2 émettant vers 10 µm et des caméras thermiques à microbolomètres, permet la mesure de grandes déformations et de s'affranchir des perturbations environnementales plus facilement qu'en lumière visible. Nous l'appliquons dans le cas de structures spatiales subissant des cyclages thermiques en régime cryogénique sous vide, ce qui induit des déplacements de grande ampleur. Nous passerons en revue les différentes expériences effectuées au Centre Spatial de Liège et discuterons des recherches en cours, notamment pour utiliser des longueurs d'onde plus grande (ondes Terahertz) [less ▲]

Le marché de l’accompagnement des chômeurs a subi de grands bouleversements ces dernières décennies suite à l’intervention de l’Europe. Les services publics de l’emploi doivent déléguer une partie de leur mission d’accompagnement des demandeurs d’emploi aux opérateurs privés. Ces derniers soumettent, dans le cadre d’appels à marchés organisés par l’Office de l’Emploi, des projets d’accompagnement et de formation à destination des chômeurs. Ce livre invite à regarder les coulisses de l’activation des demandeurs d’emploi à travers le prisme des partenariats publics-privés dans le champ de l’emploi dont le but principal est la réinsertion socioprofessionnelle des chômeurs. Il porte plus particulièrement sur les collaborations établies entre les services publics de l’emploi et les prestataires privés d’insertion socioprofessionnelle, qu’ils aient un statut d’opérateur privé marchand ou non-marchand. Pour ce faire, nous y proposons un modèle original d’analyse de la relation partenariale fondé sur l’articulation de la théorie de la justification, de la sociologie de la confiance et de la théorie de la capacitation, où la confiance apparaît comme un outil d’analyse de la relation entre les parties-prenantes du partenariat. Nous cherchons à comprendre et à décoder le fonctionnement de ces partenariats au niveau des processus d’autonomisation (passage d’un niveau interpersonnel de la confiance à un niveau systémique) et de capacitation (acquisition de capacités supplémentaires par les membres) du partenariat. Pour réaliser cette recherche, nous avons accompagné dans leur travail quotidien les agents des services partenariats de trois services publics de l’emploi qui sont Actiris (Bruxelles-Capitale), le Forem (Wallonie) et l’Office cantonal pour l’emploi (Genève). En complément, nous avons effectué des dizaines d’entretiens avec ces agents et les opérateurs privés pour décoder la manière dont ils vivent ces collaborations. [less ▲]

The European system for fire testing and classification of loadbearing building elements lacks consistency because the two standards that have to be applied prescribe different criteria for assessing the loadbearing performance. This article analyzes the implications of the present conflict between the standard for testing and the standard for classification. The prescribed criteria for loadbearing performance are related to the exceedance of deflection and rate of deflection thresholds. A database of 46 fire resistance tests performed at the University of Liege is collected that contains the time at which these thresholds are reached in fire tests with different typologies of elements (walls, floors, columns and beams). Then, the loadbearing performance (and hence the fire resistance rating) can be derived according to the two standards. The evolutions of deflection and rate of deflection during the tests are also analyzed to gain a better understanding of the adequacy of the standards. The selection of one or the other standard affects the time at which “failure” is deemed to occur in fire tests. Statistically speaking, the difference in terms of failure time that results from using one or the other standard has a 25% probability to exceed 10%. In certain cases, this results in a difference in fire resistance rating; this was observed for 3 of the analyzed tests. The apparent contradiction in two codes in application has potential practical implications and therefore needs to be solved. The article suggests some guidelines for defining homogenized and consistent criteria. [less ▲]

Future Internet has been a hot topic for the last decade. One of the approaches put forward in order to revise the Internet architecture is LISP~--~Locator/ID Separation Protocol, which leverages the separation of the identifier and the locator roles of IP addresses. Contrary to the classical push model used by the BGP-based routing architecture, LISP relies on a pull model. In particular, routing information is pulled from a new network element, the Mapping System, to provide the association between the identifier (i.e., the address used to identify a host inside a domain) and a list of locators (i.e., the addresses to locate an attachment point) upon an explicit query. In this paper, we evaluate a LISP Mapping System deployment in the public LISP Beta Network from two standpoints: Stability and Consistency. Our measurements show that the mapping information is stable over time and consistent between the different mapping entities and the vantage points. Our analysis shows that there are cases where the Mapping System is unstable and/or inconsistent, hence, beside proposing a taxonomy in order to classify them, we carry out an in-depth investigation of such cases so to provide hints on how to improve the performance of LISP.

Beside its long-term control by steroids, male sexual behavior is also modulated by neuroestrogens in a dynamic way (within minutes) in a number of species ranging from fishes to mammals. Studies in male Japanese quail have also identified following exposure to a receptive female a rapid decrease in the activity of brain aromatase (AA) the enzyme responsible for the conversion of androgens into estrogens. These effects occur mainly within the medial preoptic nucleus (POM), a sexually dimorphic structure of the preoptic area that plays a key role in the activation of male sexual behavior and contains the highest AA in the brain. In vitro studies demonstrated that AA can be rapidly inhibited by calcium-dependent phosphorylations of the enzyme triggered by the activation of AMPA and kainate receptors. We confirmed here this rapid effect of glutamate on AA by injecting kainate in the POM of anesthetized males and measuring AA in the tissue after brain collection. AA in POM was inhibited in the kainate-injected hemisphere compared to the control hemisphere injected with vehicle. In a second experiment, we showed by in vivo microdialysis that glutamate is released in POM during copulation. These results thus suggest that glutamate controls dynamic changes of AA that occur in the brain during sexual interactions. To confirm that the decrease in AA leads to an actual reduction of local estradiol concentration, we quantified via microdialysis and radioimmunoassay changes in estradiol concentration in the male POM during sexual interactions with a female. Surprisingly, a dramatic elevation of estradiol was observed during copulation. Estradiol has been shown to enhance acutely male sexual motivation, therefore the function of its increase in the POM could be to maintain motivation during the entire sexual encounter. The decrease of AA observed ex vivo after copulation would then reflect a compensatory mechanism to restore baseline pre-copulatory conditions. Importantly, these results highlight that although long-term changes in AA are often used as a proxy for local estradiol concentrations, these two measures can show major short-term discrepancies possibly reflecting variations in estrogen turnover.
