La problématique traitée est celle de la transition des éleveurs vers des pratiques de gestion du parasitisme ayant un impact moins négatif sur l'environnement. Cette recherche est basée sur un travail collaboratif avec les éleveurs permettant d'aborder la question du parasitisme animal à travers une exploration du « système-bouse » formé par la bouse, ses insectes coprophages, leurs prédateurs, et les vermifuges. Notre première hypothèse de travail est la suivante : dans la gestion du parasitisme en élevage bovin, la mise en place de pratiques ayant un impact moins négatif sur l'environnement (et donc sur les coprophages et leurs prédateurs) nécessite que les éleveurs s'intéressent à cette problématique et que celle-ci fasse sens pour eux. Notre but premier est donc de saisir quelle est leur propre compréhension du « système-bouse » et par quels biais il est possible d'intéresser les éleveurs pour modifier leurs pratiques. Dans un second temps, nous nous intéressons à la question de la transformation des pratiques anti-parasitaires chez les éleveurs wallons. Pour ce faire, nous mobilisons le cadre analytique ESR (Hill 1995) ainsi que la typologie des conceptions de la santé animale de Cabaret et Nicourt (2011). À travers les parcours des éleveurs rencontrés, nous cherchons à comprendre comment les éleveurs gèrent le parasitisme, quelle est leur conception de la maladie animale, dans quelle logique ils se situent. Ces parcours mettennt en évidence plusieurs logiques possibles de transformation des pratiques anti-parasitaires et d'apprentissage de nouvelles pratiques. Leur analyse souligne également l'importance du rôle que peut jouer la symbolique des parasitoses dans ces transformations. Finalement, nous entamons une réflexion sur les convergences et divergences entre les alternatives proposées et le système de gestion du pâturage et du troupeau chez les éleveurs. L'étude se conclut par un bilan des avantages et limites des différentes approches du modèle ESR dans le cas de la gestion du parasitisme ainsi que des freins et obstacles à la transformation à la reconfiguration des pratiques anti-parasitaires en Région wallonne. Il apparaît enfin que les éleveurs ne sont pas les seuls acteurs dans la gestion de la maladie animale et qu'une transformation est également nécessaire au sein des autres catégories d'acteurs impliquées.

High Strength Steel (HSS) characterized by yield strength ranging between 500MPa to 700MPa has been available for many years. However, its use in onshore engineering is quite restrictive. Reasons were threefold: i) Eurocodes covered steels with yield strength up to 460MPa; ii) higher costs than regular steel; iii) lack of conceptual design with HSS. Nonetheless very recently, there has been a growing trend for the use of HSS in tubular structures thanks to Eurocode 3 Part 1-12 (2006), that extended its scope to steel grades up to S690/S700MC. Along this line, the HITUBES project intended to develop performance-based designs and assessment procedures to make full use of HSS tubes up to S700MC for structures subject also to extreme repeated loads; in fact Eurocode 3 Part 1-12 imposes many limitations at the material, structural and design level. The ambitious targets are to increase the performance of tubular structures, reduce weights, construction and operating costs. The project covered the period 01/07/2008-31/12/2011, and main research work focussed on several aspects listed herein: literature survey; selection of finite element-based and identification dynamic analysis codes; selection of realistic Case Studies and FE analysis for the evaluation of actions and stresses; structural identification and health monitoring of a cable-stay and arch footbridges; tests planning and execution including welding procedure specifications; simulations of welded and bolted connections under monotonic, low-cycle and high-cycle fatigue loadings; simulation of Case studies and reliability analysis for quantification of realistic performance scenarios; SWOT analysis and monitoring of project activities.

In the proposal that follows we present a detailed concept for the science case, instrument requirements, technical design, calibration and operations, management structure, and financial plan for the Jupiter system Ultraviolet Dynamics Experiment (JUDE), which will provide an outstanding solution to the UV instrumentation requirements for the JUICE mission. The JUDE instrument will represent a novel technical capability in UV instrumentation for planetary science, and will deliver the first true UV imaging capability beyond Earth orbit. The JUDE instrument design consists of two separate channels – the imaging channel (ImaC) and the spectrograph channel (SpeC), neither of which has any moving parts. This simple combination of two autonomous channels allows a true image and a spectrum at FUV wavelengths to be obtained simultaneously, allowing science goals to be realised which are not possible with a traditional scanning-slit imaging-spectrograph design The international consortium assembled to build the JUDE instrument is formed of two institutes from two European countries, and one from the United States. Prof. Denis Grodent (Université de Liège, Belgium) will act as the PI for the entire instrument team and the ULg/CSL team will provide a substantial hardware contribution to the instrument in the form of the optics, coatings, and Data Processing Unit (DPU). Dr Emma Bunce (University of Leicester, UK) will act as Co-PI for the instrument and the UoL team will supply the Micro-Channel Plate (MCP) detectors and read-out electronics. Prof. John Clarke (Co-I) of Boston University, USA will provide the grating element for the spectral channel of the instrument, in addition to instrument calibration activities. The science Co-Is are gathered from multiple institutes/nations including Belgium, UK, Germany, Italy, and the United States (see Part 1 for the full team list). Collectively, the team have decades of expertise in the areas of outer planet magnetospheres, planetary auroral and atmospheric emissions and surface UV observations from multiple platforms including Cassini UVIS, Juno UVS, Hubble Space Telescope, and numerous terrestrial missions. The team also have roles on non-UV instruments which will maximise the interpretation of the JUDE data. The two instrument channels are built on proven and robust technology with much flight heritage (e.g. Juno, Cassini, BepiColombo, IMAGE, ROSAT, Chandra, Voyager, Freja, DE-1, Swift). More specifically, the optics and focal plane detector proposed for the JUDE instrument are widely based on previous designs by CSL, at the ULg and UoL, for the FUV Spectro-Imager on the NASA IMAGE spacecraft, the UV Spectrograph on the NASA Juno mission to Jupiter, and the ROSAT Wide Field Camera. The data return from the instrument will greatly benefit the European and international science communities in planetary and terrestrial sciences, and the knowledge obtained will be generally applicable to broader astrophysics disciplines (e.g. extrasolar planetary physics). In answering the UV science objectives for the JUICE mission the JUDE instrument will clearly address the ESA Cosmic Vision Themes 1: What are the conditions for planet formation and the emergence of life? and 2: How does the Solar System work? The JUDE images (in particular) provide a clear path towards a high-level related programme of education and public outreach which the JUDE team are well equipped and keen to exploit. The JUDE instrument will contribute to all of the UV-related science objectives of JUICE, plus additional science objectives not listed in the Science Requirements Matrix. - At Ganymede and other moons (Europa and Callisto) JUDE will contribute directly to breakthroughs in the following scientific areas: 1) the characterisation of local environment, specifically through the first investigation of the morphology and variation of Ganymede’s aurora. A clear understanding of the auroral and atmospheric emissions at Ganymede will provide vital information on their formation mechanisms and will contribute to studies of the interaction of the Ganymede magnetosphere with Jupiter’s magnetosphere; 2) the first detailed observations of the satellites’ atmospheric (exosphere/ionosphere) composition and structure through measurements of their atmospheric emission and absorption spectra during multiple stellar occultation opportunities; and 3) the study of the satellites surface composition using surface reflectance measurements. The measurements at UV wavelengths are essential because they allow the study of the relationship between the satellites’ surface weathering, their atmospheres and the external environment which is mainly affected by the surrounding Jovian magnetosphere. By carefully studying processes at the surface and in the satellites’ atmospheres together, JUDE will provide the information required to distinguish between two classes of compositional heterogeneities at the satellites’ surfaces: 1) heterogeneities that arise from interaction with the external environment; 2) heterogeneities that arise from dynamical interaction with the subsurface. - With respect to Jupiter, JUDE will: 1) provide “state of the art” measurements of the Jovian atmospheric dynamics and transport through high temporal and spatial resolution auroral imaging; 2) allow a new understanding of the Jovian magnetosphere as a fast rotator through interpretation of the Jovian aurora as direct evidence for the 3D magnetosphere dynamics – a view which is continuously available in the planet’s upper atmosphere (independent of the spacecraft location within the magnetosphere); 3) investigate the magnetosphere as a giant accelerator through observations of the field-aligned current systems responsible for acceleration of electrons (and production of aurora); 4) discover the plasma sources and sinks of the moons through auroral imaging of the moon footprints in Jupiter’s atmosphere as a witness of the electromagnetic interactions taking place; 5) obtain new information on Jupiter’s atmospheric structure and composition through multiple stellar occultation opportunities. In addition, JUDE will make remote observations of the Io torus emissions and will provide the first in situ observation of the variability of the torus, over the lifetime of the mission, providing important information about the internal activity of the moon. JUDE offers a unique opportunity to obtain the first concurrent datasets of the different coupled elements of the Jupiter system: Io's atmosphere, aurora, the plasma torus, the Jovian plasma sheet and the Jovian aurora. The JUDE imaging and spectral channels are both designed to capture FUV lines from sulphur ions in the Io plasma torus. Finally, JUDE’s remote sensing capability offers an exciting opportunity to discover the Europa “plume” activity that may be present, through limb observations during flybys and from more distant observing locations. The Ganymede-focused and moon related science objectives will be addressed in the Ganymede orbit phase and during the multiple moon flybys, whilst the Jupiter science will be predominantly achieved during the Jupiter Equatorial Phases and during the high-inclination phase. The JUDE UV imager and spectrograph will produce discovery level science at Ganymede and the first true 2D UV images from Jupiter orbit. The exceptional JUICE trajectory affords many opportunities for breakthrough science discoveries in accordance with the SciRD; in addition to those, it provides unprecedented opportunities to directly witness the electromagnetic connection between Ganymede and Jupiter by making the first simultaneous UV observations of the respective atmospheres within the JUDE field-of-view. This is possible as a direct consequence of the JUDE true imaging capability. To successfully meet the science requirements outlined above, the JUDE ImaC has a spatial resolution of 20 arcsec over a circular field-of-view with 6˚ diameter, which allows a 100 km spatial resolution on Jupiter from Ganymede orbital distances (and 20 m resolution on Ganymede from 200 km, for example). JUDE’s ImaC mirrors and detector window will be covered with multilayer coatings which efficiently select a narrow bandpass from 130 to 143 nm, to allow measurements of the faint Oxygen lines at 130.4 nm and 135.6 nm in Ganymede’s (and other moon’s) atmosphere. This bandpass also allows observations of the SIV lines (between 140.5 and 142.4 nm) emitted within the Io plasma torus and in Io’s atmosphere. The bright Jovian emissions will also be suppressed within this bandpass which will necessarily limit the count rate to an acceptable level. The Ly-α line at 122 nm will be largely excluded as will the reflected sunlight longward of 150 nm. The sensitivity of the ImaC is 50 Rayleigh (at 3-sigma). The SpeC has a spectral resolution of 0.5 nm in order to meet the requirements of the SciRD, and has a field-of-view which is a 6˚ x 0.1˚ slit co-aligned with, and centred on, the ImaC circular field-of-view. The lower wavelength of the SpeC bandpass is set to ~110 nm in order to include the bright Ly-α line (useful to study the H corona) in a region of reduced transmission. The upper wavelength limit, ~195 nm, is such that transmission is slowly decreasing in the 180-195 nm spectral region, allowing measurements of the moon’s albedos beyond 165 nm, as well as the detection of compounds such as CO2, SO2, O2, O3, H2CO3 and H2O2 by comparing JUDE reflectance spectra to those obtained in laboratory studies. FUV emission lines from S and O are also observable within the bandpass and B-type stars emitting within this waveband will allow occultation experiments to be performed, to determine the composition and structure of the moon’s atmospheres and the detection of a possible Europa plume. The same is true for the Jovian atmosphere for which attenuation by H2 and hydrocarbons allows determination of the atmospheric structure. The sensitivity of the SpeC is 10 R/nm (at 3-sigma). The JUDE instrument channels: ImaC and the co-aligned SpeC, are both operating within the 110–195 nm range. Each channel has independent optics and detector elements, providing a level of redundancy such that loss of either imager or spectrograph does not constitute an entire loss of science. In contrast to more conventional (e.g. scanning or pushbroom) imaging spectrographs, JUDE can provide high time resolution (<1 second) high throughput images over a wide field of view (6° diameter) with no time variation across the field – a capability which is critical in gaining a better understanding of the complex dynamical processes taking place in the Jovian magnetosphere. The primary optic in each channel is a multilayer-coated mirror operating at normal incidence, with flight heritage in the form of the scan mirror in the Ultraviolet Spectrograph (UVS) now en-route to Jupiter onboard JUNO. The imaging channel uses a secondary mirror to of a similar type to focus the image onto the focal plane detector, while in the spectrograph channel, the secondary is a spherical, holographic grating. The spectrograph design is simple, with heritage in airglow spectrographs flown on terrestrial UV missions, and the Imaging UV Spectrograph for MAVEN. The grating element is produced by Jobin-Yvon, who have produced diffraction gratings for major missions including SOHO and HST. Each channel includes an identical microchannel plate (MCP) detector with the robust, radiation-tolerant performance required for a mission in the formidable environment of Jupiter. Such detectors are well proven, having flown on many missions including ROSAT (UoL heritage). They have also operated in the vicinity of Jupiter, in the focal plane of the UV spectrograph onboard the Voyager probes. The detector readout is a new type of capacitive division image charge readout (C-DIR; invented by Dr Jon Lapington) which offers, simultaneously, high spatial resolution and high count rate performance. Adaptive signal processing capabilities allow JUDE to accommodate the very wide dynamic range expected, from observations of Jupiter’s auroral ovals which emit with intensities of mega Rayleighs, to the weak (few tens of Rayleigh) emissions found at Ganymede. The readout structure is simple and robust, and has already been demonstrated in laboratory trials, while the electronics chain has its heritage in particle physics detectors, and has therefore been designed with radiation tolerance as a primary consideration. Pre-launch and in-flight calibrations will be implemented to assure that the JUDE data are suitable for quantitative scientific analysis. The proposed JUDE configuration successfully meets the scientific objectives of the JUICE mission. Our decision to implement an imaging channel instead of covering the MUV waveband increases the whole mission’s scientific output while remaining compliant with the MPDD. Due to its high-temporal resolution read-out system, JUDE is capable of producing volumes of data that are incompatible with the limited telemetry allocated to the UV instrument, even after a modest compression factor is applied. We therefore have proposed a mode of operation (the JUDE reference mode) which takes 1 minute snapshots over an observation opportunity (for example during a flyby sequence). Using this reference mode, and taking the maximum count rate estimates for the various targets, we find that the JUDE data volume is compliant with the tight allocation for the UV instrumentation of 40 GBytes/year The JUDE design presented in this proposal is above the mass allocation. We believe that all components of our design are necessary to reach the scientific goals of JUICE mission and that any major changes (such as the descope of a channel) will be at the considerable expense of the expected science return. However, further optimisation will be performed during the Phase A to bring JUDE into the allocated mass envelope while compromising its scientific return only slightly. We propose an efficient management structure with clearly delineated responsibilities. The Principal Investigator, Prof. Denis Grodent (Be) will take on the responsibilities as specified in the JUICE payload Announcement of Opportunity, supported closely by the Co-PI Dr Emma Bunce (UK) and by the team of Co-Investigators. The contribution of each country is represented by lead Co-Investigators: Prof. John Clarke (Boston University), Dr. Candy Hansen (PSI), and Dr Xianzhe Jia (University of Michigan), and Dr Nigel Bannister (UK) as CoI and Instrument Scientist (see Figure 1 below). The philosophy has been to assign well-defined tasks to each institute with an overall project manager to coordinate the efforts. The Consortium Project Manager (Etienne Renotte, CSL) will execute the managerial tasks relevant to the instrument development. The Product and Quality Assurance management will be implemented by all hardware contributors. Each consortium institute has a local project manager for their respective work packages, reporting to the Consortium Project Manager. The outreach potential of JUDE’s instantaneous wide field images is enormous. The potential PhD students of 2030 who we hope to educate and inspire with JUDE images and spectra are currently 3 years old; their supervisors are in secondary school. The team regards the educational aspects of the instrument and data as particularly important, and we plan a comprehensive JUDE/JUICE programme of outreach to schools and to the public, as part of the project and one which will be initiated upon selection. The national funding agency of Belgium serves as the Lead Funding Agency (LFA) for the JUDE instrument. The letters of endorsement from Belgium and United Kingdom are included in this proposal. Although the agencies endorse their respective national contributions, funding will be secured after the selection of the instrument proposal, according to the usual procedure. [less ▲]

The present document summarises recent studies and developments investigating the behaviour of composite frames, for discussion within TC11 Committee. Also, possible aspects to be investigated in future are identified. The document is organised as follows: • First, the global frame behaviour is considered in § 2; • Then, the structural members which can be met in a composite structure, i.e. the composite slabs, the composite beams, the composite columns and the composite joints, are considered in separate paragraph from § 3 to § 6; • A specific paragraph is also dedicated to the possible long term effects on composite members (§ 7); • Finally, a conclusion is drawn in § 8, summarising recent improvements in the knowledge about composite frame design and possible further developments. A first draft of this document was presented at the TC11 meeting held in Liège on March 2010. The present document is an updated draft to be discussed at the TC11 meeting held in Valencia on october 2012. Remark: the aspects related to the response of composite structures subjected to seismic or fire actions are not reported here as they are covered by other more “transversal” technical committees of ECCS (TC3 for the fire and TC13 for the seismic action).

The results of a 24 year survey of a community of reptiles typical of northern Europe along a 19 km long railway track in the South of Belgium suggests that: i) four among the six species (Anguis fragilis, Podarcis muralis, Zootoca vivipara, and Natrix natrix helvetica) exhibited stable abundance levels and distribution patterns; ii) Vipera berus strongly decreased and is now nearly extinct; iii) Coronella austriaca appeared in the course of the survey and its populations sharply increased. The decrease of Vipera berus can be explained by the degradation of some of its habitats. The causes of the increase of Coronella austriaca are unknown but might be linked to climate change.

Contribution to the development of teaching capacity and training for the improvement of quality of the medicines. Contextualisation: The quality of medicines is a major problem of public health in the development countries. Since 1990, this situation has deteriorated becoming worried mainly in the Central African region due to the degradation of social, economic and politic life, consequence of a long period of conflict and war. The resurgence of non-controlled drugs, the sale of illicit, deteriorated and even falsified drugs are real examples in the current practices, that is making difficult and even practically impossible an access to a safe, reliable and efficient medical treatment. It is known that even if a diagnosis is correctly made and a medical treatment is correctly prescribed, this treatment is doomed to failure if the medicine is not of a good quality. Democratic Republic of Congo (DRC) and Rwanda are among the countries that are facing such situations. Description of project purpose: The principal objective of this project is to contribute to the improvement of the quality of medicines and thus, of the public health in DRC and in Rwanda. More precisely, the project aims to strengthen the local capacity in order to respond to the need in the quality of medicines and to develop a platform of people in the pharmaceutical sector in the field of quality assurance and control. According to this main objective, the project aims in one hand to train people working in the pharmaceutical sector including the academic, the legal and the industrial, and in another hand to develop the tools to contribute to the improvement of the quality of medicines. Training and qualification of people, improvement of the teaching and making available the control documentation on quality are the sub-objectives pursued in the framework of this project. Chapter 2 : Six main activities are undergone in this project: The first activity is the seminar that is organised in order to promote the project and to initiate the importance of knowledge of the quality of medicine by awareness of the different authorities from government, from the churches and from the health sectors. The seminar is the preliminary step of this project that is done to select the different candidates. The second activity concerns the theoretical training, focused on the basis of the quality of drugs, the drug manufacturing and drug control / analysis taking into account the activity sector of each candidate. This activity is important since most of the candidates have been graduated a long time ago while working for a long time. This activity as well as the seminar is held in the beneficiary countries for one month. The trainers are among the Professors and Researchers from the “University of Liège”, the “University Libre de Bruxelles” and the “University Catholique de Louvain”, in Belgium. They are selected on basis of their expertise. The topics considered are the Quality Assurance, the Regulatory, the Statistical applied in the pharmaceutical industry, The Manufacturing and The Quality control of medicines, the Management in the Pharmaceutical sector. The theoretical training by e-learning using internet occurs in the third place. It is done as a complement to the second activity since it allows the candidate to have access to different and more documents available through the web site platform created for this purpose. This mode of teaching allows also the candidates to interact with other trainers concerning a particular subject of their working sector. The fourth activity is the practices that are done in Belgium in the different facilities of the laboratories associated to this project. This allows the different candidates to materialize the knowledge acquired during the theoretical teaching while considering their working sector, and to familiarize with the procedures dealing with their sector. The fifth activity is related to a specific training for auditor or evaluator. Indeed, this training is a specific requirement namely the creation of Federal Agency of Drug in DRC. The need is to improve the capacity of such organism to carry out efficiently the audits and evaluations of drug registration files before their commercialization. Finally, the sixth activity is the reintegration of the candidates within their professional environment. Considering the importance of this aspect, an accompanying is necessary to ensure that the acquired knowledge is valued in the professional environment. Chapter 3 : The expected impact At the end of this project, we expect that the different Authorities are aware with regard to the quality of drugs, the activities in the pharmaceutical sectors namely, the legal and industrial are improved since the actors are trained, qualified and gained competence. We expect also the improvement of teaching capacity in Pharmacy Schools taking into account the need of the pharmaceutical market, with the possibility of starting the post-university teaching programs. Finally, we expect the efficiency of activities in the pharmaceutical sector for the benefit of the DRC and Rwanda populations.

Ces dernières années, la progression de la production avicole en Wallonie est, en grande partie, liée au développement de filières dites de qualité différenciée. En 2009, ce sont près de 2.000.000 de poulets qui ont été associés à ce type de production. Cependant, contrairement au poulet standard pour lesquels les pratiques sont très standardisées, les pratiques d’élevage en qualité différenciée peuvent varier, notamment la génétique, l’âge et le poids à l’abattage, le sexe de l’animal, l’accès à un parcours… Ces variations peuvent influencer l’homogénéité de la qualité organoleptique de la viande de poulet au sein d’une même filière ainsi que la perception (et la confiance) des consommateurs vis-à-vis de la viande des poulets qui en sont issus. L’objectif de ce projet est d’étudier et d’objectiver de manière scientifique la qualité organoleptique de la viande de poulet de chair au sein de trois filières avicoles de qualité différenciée afin de fournir aux détenteurs de ces filières des informations quant aux facteurs susceptibles de modifier la qualité organoleptique de leurs produits ainsi que la perception de ceux-ci par les consommateurs.

A persistent and strong negative North Atlantic Oscillation (NAO) index was responsible for southerly air flow along the west of Greenland, which caused anomalously warm weather in winter 2010-11 and summer 2011. The area and duration of melting at the surface of the ice sheet in summer 2011 were the third highest since 1979. The lowest surface albedo observed in 12 years of satellite observations (2000-2011) was a consequence of enhanced surface melting and below normal summer snowfall. The area of marine-terminating glaciers continued to decrease, though at less than half the rate of the previous 10 years. In situ measurements revealed near record-setting mass losses concentrated at higher elevations on the western slope of the ice sheet, and at an isolated glacier in southeastern Greenland. Total ice sheet mass loss in 2011 was 70% larger than the 2003-09 average annual loss rate of -250 Gt y-1. According to satellite gravity data obtained since 2002, ice sheet mass loss is accelerating. [less ▲]

Ce rapport à la Commission provinciale de Liège du Fonds piscicole de Wallonie est un dossier bibliographique qui analyse l’impact sur les populations de poissons des centrales hydroélectriques (CHE) installées sur le cours principal de l’Amblève non navigable. Il s’agit d’un grand cours d’eau (module du débit : 20 m3/s dans le cours inférieur à Martinrive-Aywaille) constitué de zones à ombre et à truite qui abritent une importante biodiversité piscicole dont notamment des poissons migrateurs amphihalins comme l’anguille européenne, la truite de mer et le saumon atlantique en cours de réintroduction en Wallonie.L’évaluation des impacts piscicoles des CHE se limite à une approche très préliminaire consistant à apprécier de manière théorique (par rapport à des modèles élaborés en France) les ordres de grandeur des entraînements vers les turbines et des mortalités des populations migratrices (surtout les anguilles argentées et les smolts de Salmonidés) attendues sur les différents sites, compte tenu des caractéristiques connues des prises d’eau (grilles), des turbines (Kaplan, Francis, Banki ; grandeur des roues, vitesse de rotation, débit turbiné), de la taille des poissons et des possibilités de dévalaison par une voie autre (déversoir de barrage, exutoire de dévalaison) que le passage dans les turbines. Partant de ces premiers résultats, le rapport détaille les actions à entreprendre sur chaque site hydroélectrique pour le rendre moins pénalisant pour les poissons migrateurs en dévalaison et dans certain cas, en montaison comme à la cascade de Coo. Il propose aussi quelques recommandations générales applicables à l’évaluation objective de l’impact piscicole de tout site hydroélectrique et à l’atténuation de cet impact. Ainsi, en matière biologique et piscicole, il apparait prioritaire de mettre en place des programmes d’études permettant : i) de caractériser qualitativement (taille des poissons et périodicité des mouvements) et surtout quantitativement (effectifs numériques et biomasse) les migrations de dévalaison des principales espèces cibles dans les cours d’eau concernés des zones à ombre et à truite et ii) d’estimer les mortalités réelles des poissons dans les différents types d’installation de production d’hydroélectricité.

L’objet de l’étude présentée ici consistait à voir comment la collaboration entre médecins généralistes et gériatres peut être conçue autour de la personne âgée, pour maintenir cette dernière dans son milieu de vie. Il y est question d’avoir un référent spécialiste lorsque la dimension gériatrique de la prise en charge s’exprime avec acuité. Dès lors, l’étude cherchait à cerner comment les médecins généralistes conçoivent cette collaboration avec les gériatres pour leurs patients âgés à domicile et en maison de repos, quels sont les atouts et contraintes de la première ligne de soins, ainsi que les pistes sur lesquelles s’appuyer pour concevoir une collaboration efficace et efficiente.
