The distrbution of the wild mammals of Belgium has been intensively stutied during the years '78-81'. It was the first time that such a work was undertaken in Belgium and could lead to a better understanding of the current status of the different species. Conservation measures were olso proposed to the political authorities who thereafter edicted a legal protection of the most vulnerable species. Unfortunately, habitat protection is rather unachieved and the situation of the most endangered species is still getting worse. [less ▲]

Fluoride has been used over the past 25 years as a potential treatment of established osteoporosis. Notwithstanding a consensus over its ability to stimulate bone formation, discrepant results were published relating to its antifracture efficacy. Differences in the published results are likely to be linked to therapeutic regimens, fluoride formulation, and the nature of the treated populations. A critical review of the published data evaluating the antifracture efficacy of fluoride leads to the conclusion that this substance should be mainly used in postmenopausal women with low bone mineral density without prevalent fracture, that low-dose fluoride for a prolonged period should be preferred to high doses for short-term treatment, and that gastroresistant preparations are likely to be better tolerated than fluoride.

Despite being controlled in many developed countries, scrapie remains endemic in many parts of the world. Economic losses result from mortality and culling of small ruminants and from market restrictions. Moreover, it is difficult to develop all-inclusive guidelines that could establish a scrapie-free status for a country. Unfortunately, the global picture remains incomplete because in many countries confusion still remains regarding the clinical picture of scrapie and information is not available owing to the absence of adequate epidemiosurveillance networks. Currently, the predominant theory is that PrPSc is the infectious agent where host genetic factors play a central role. The precise transmission routes of scrapie and their relative contributions to the overall transmission intensity remain poorly documented and the physiopathology is not fully understood. However, it is evident that the purchase of female sheep from scrapie flocks, sharing pastures with scrapie flocks, sharing breeding rams and genetic host susceptibility are the main risk factors for the spread of the disease. A better understanding of the epidemiology of scrapie would greatly aid the development and evaluation of control and eradication strategies that were mainly based on selective depopulation of infected animals and genetically susceptible and/or related animals and also on the biosecurity and the use of selective genetic breeding programmes in healthy flocks. Some numbers of a new transmissible spongiform encephalopathy (TSE) form in small ruminants (atypical scrapie) have meanwhile been identified by TSE rapid testing using an assay, which also recognizes comparatively less proteinase K-resistant PrPSc. Uncertainties remain regarding the pathogenesis of this new TSE form, as well as regarding its potential transmissibility within the affected species and to other species. Thus far, no bovine spongiform encephalopathy (BSE) cases have been confirmed in sheep under natural conditions (a report of vertical transmission after experimental infection merits attention), but two historical cases of BSE in goats born in the 1990s have been identified. Currently BSE must also be considered in the differential diagnosis of scrapie. The development of prevention and control programmes should be assisted by new scientific findings. [less ▲]

A globally integrated carbon observation and analysis system is needed to improve the fundamental understanding of the global carbon cycle, to improve our ability to project future changes, and to verify the effectiveness of policies aiming to reduce greenhouse gas emissions and increase carbon sequestration. Building an integrated carbon observation system requires transformational advances from the existing sparse, exploratory framework towards a dense, robust, and sustained system in all components: anthropogenic emissions, the atmosphere, the ocean, and the terrestrial biosphere. The paper is addressed to scientists, policymakers, and funding agencies who need to have a global picture of the current state of the (diverse) carbon observations.We identify the current state of carbon observations, and the needs and notional requirements for a global integrated carbon observation system that can be built in the next decade. A key conclusion is the substantial expansion of the ground-based observation networks required to reach the high spatial resolution for CO2 and CH4 fluxes, and for carbon stocks for addressing policy-relevant objectives, and attributing flux changes to underlying processes in each region. In order to establish flux and stock diagnostics over areas such as the southern oceans, tropical forests, and the Arctic, in situ observations will have to be complemented with remote-sensing measurements. Remote sensing offers the advantage of dense spatial coverage and frequent revisit. A key challenge is to bring remote-sensing measurements to a level of long-term consistency and accuracy so that they can be efficiently combined in models to reduce uncertainties, in synergy with groundbased data. Bringing tight observational constraints on fossil fuel and land use change emissions will be the biggest challenge for deployment of a policy-relevant integrated carbon observation system. This will require in situ and remotely sensed data at much higher resolution and density than currently achieved for natural fluxes, although over a small land area (cities, industrial sites, power plants), as well as the inclusion of fossil fuel CO2 proxy measurements such as radiocarbon in CO2 and carbon-fuel combustion tracers. Additionally, a policy-relevant carbon monitoring system should also provide mechanisms for reconciling regional top-down (atmosphere-based) and bottom-up (surface-based) flux estimates across the range of spatial and temporal scales relevant to mitigation policies. In addition, uncertainties for each observation data-stream should be assessed. The success of the system will rely on long-term commitments to monitoring, on improved international collaboration to fill gaps in the current observations, on sustained efforts to improve access to the different data streams and make databases interoperable, and on the calibration of each component of the system to agreed-upon international scales.

Current management of shingles relies on antiviral therapy. The efficacy of acyclovir in varicella-zoster virus replication is now well established, with a beneficial impact on zoster-associated pain, but its moderate bioavailability renders five oral daily doses mandatory. Recent anti-VZV drug research has been oriented towards agents with increased oral bioavailability. Famciclovir and valaciclovir were originally developed as oral prodrugs for^penciclovir and acyclovir, respectively, but, together with the new antivirals, sorivudine and brovavir, they appear to be effective as oral therapy for shingles. Ongoing clinical trials will determine their relative merits in the management of shingles. The experimental agents H2G, HPMPC, mappicine ketone and A-73209 have potential in the treatment of VZV and are undergoing further investigation and development. [less ▲]

Repeated imaging of Jupiter's aurora has shown that the northern main oval has a distorted 'kidney bean' shape in the general range of 90-150o System III longitude, which appears unchanged since 1994. While it is more difficult to observe the conjugate regions in the southern aurora, no corresponding distortion appears in the south. Recent improved accuracy in locating the auroral footprint emission of Io has provided new information about the geometry of Jupiter's magnetic field in this and other areas. The persistent pattern of the main oval implies a disturbance of the local magnetic field, and the increased latitudinal separation of the locus of the Io footprint from the main oval implies a locally weaker field strength. The most recent images obtained with the Hubble Space Telescope Advance Camera for Surveys (ACS) allow us to complement previous observations with the location of the auroral footprints of Io, Europa, and Ganymede in the region of interest. Their footpaths vary in parallel and form a kink in the 90-150° S3 sector which strongly suggests the presence of a magnetic anomaly in this region. [less ▲]

Infection by Herpes Simplex Virus (HSV) types I and II represent a worldwide medical problem. After the primary infection the virus establishes a life-long latency in the dorsal root ganglia and recurrences may occur at unpredictable times and rate. The most frequent clinical presentation of HSV infection is recurrent herpes labialis and herpes genitalis. The clinical expression varies according to the body site, the infected cell type, the relationship between HSV and the host immune status. Viral identification techniques such as immunohistochemistry and in situ hybridization on Tzanck smears and muco-cutanenous biopsies are helpful in the diagnosis of atypical cutaneous lesions. The treatment modalities of HSV infections include the reduction of viral load using antiviral agents, the non-specific immune stimulation of the host and specific vaccination in order to prevent new acquisition and to mitigate symptoms in already infected individuals. This review addresses various therapeutic options, their mode of action, and clinical value as well as the indications of the various drugs. [less ▲]

During the pregnancy of ruminants, different hormones and proteins are secreted by placenta or corpus luteum allowing the follow up of gestation. Among them, progesterone (P4) and pregnancy-associated glycoproteins (PAG) were proposed as laboratory tools to establish or to confirm pregnancy diagnosis. In last years, PAG assay also provided useful information for researchers working in programs focused on the follow up of trophoblastic function. Concentrations of PAG appeared as altered after the use of embryo biotechnology (in vitro fertilization, cloning by nuclear transfer, inter-specific pregnancies), according to nutritional status of pregnant females (overnourished or undernourished), or consecutive to infectious diseases leading to pathologies affecting the pregnancy in cows (Actynomyces pyogenes and Neospora caninum) and goats (Toxoplasma gondii, Listeria monocytogenes and Trypanosoma congolense). As well, in numerous studies, the association of repeated ultrasound examinations with P4 and PAG determinations allowed a better understanding of mechanisms related to embryonic and fetal mortalities: failure after artificial insemination or embryo transfer techniques, large offspring syndrome after in vitro fecundation and cloning.

Calcium phosphate (CaP) has traditionally been used for the repair of bone defects because of its strong resemblance to the inorganic phase of bone matrix. Nowadays, a variety of natural or synthetic CaP-based biomaterials are produced and have been extensively used for dental and orthopaedic applications. This is justified by their biocompatibility, osteoconductivity and osteoinductivity (i.e. the intrinsic material property that initiates de novo bone formation), which are attributed to the chemical composition, surface topography, macro/microporosity and the dissolution kinetics. However, the exact molecular mechanism of action is unknown. This review paper first summarizes the most important aspects of bone biology in relation to CaP and the mechanisms of bone matrix mineralization. This is followed by the research findings on the effects of calcium (Ca(2)(+)) and phosphate (PO(4)(3)(-)) ions on the migration, proliferation and differentiation of osteoblasts during in vivo bone formation and in vitro culture conditions. Further, the rationale of using CaP for bone regeneration is explained, focusing thereby specifically on the material's osteoinductive properties. Examples of different material forms and production techniques are given, with the emphasis on the state-of-the art in fine-tuning the physicochemical properties of CaP-based biomaterials for improved bone induction and the use of CaP as a delivery system for bone morphogenetic proteins. The use of computational models to simulate the CaP-driven osteogenesis is introduced as part of a bone tissue engineering strategy in order to facilitate the understanding of cell-material interactions and to gain further insight into the design and optimization of CaP-based bone reparative units. Finally, limitations and possible solutions related to current experimental and computational techniques are discussed. [less ▲]

Based on the time-dependent Ginzburg-Landau equations, we study numerically current-driven vortices in a micrometer size square type-II superconductor. We demonstrate that the applied current significantly influences the dynamics of the vortices entering the sample. Strikingly, we find that a giant vortex can be created by the current-assisted collision of two singly quantized vortices. [less ▲]

We investigate experimentally and theoretically the vortex dynamics in a superconducting film with nanoengineered open vortex traps which provide tunable pinning, ranging from no pinning for a certain current direction to finite pinning when reversing the current flow. The design is based on the confinement of the vortex motion within two repulsive walls, one with periodic microprotrusions and the other one smooth. Clear commensurability effects are seen if the bias current drives the vortices inside the traps, whereas these effects are much less pronounced when the current pushes the vortices against the smooth surface. For small periods of the protrusions or large vortex sizes, the properties displayed by the vortices, pushed against these two surfaces of dissimilar roughness can be thought of as due to the change of effective sliding friction.

Le présent volume constitue les actes du onzième colloque de l'AiRDF, qui s’est tenu à Liège, du 26 au 28 aout 2010, et avait pour thème la question suivante : « Quelles progressions curriculaires en français ? » Poser cette question, c’était donner à entendre que les curriculums (les plans d’action) et les progressions (les étapes prévues pour réaliser ces plans) pouvaient différer sensiblement d’une institution scolaire à l’autre. Il s’agissait alors de se demander quels étaient hier et quels sont aujourd’hui les finalités de l’école et les buts de la formation disciplinaire en français. Il s’agissait de se demander si ces finalités et ces buts avaient été, jadis ou naguère, explicitement énoncés et s’ils le sont à l’heure actuelle. Il s’agissait de se demander à quel point leur énoncé et leur poursuite par l’ensemble des acteurs impliqués reflètent les tensions de notre discipline, tensions liées, d’une part, à son identité problématique, et, d’autre part, aux déterminations socioculturelles. Il s’agissait de réfléchir aussi aux implications d’une évaluation scientifique de la mise en oeuvre du curriculum et aux conditions de possibilité d’une progression curriculaire qui réduirait les tensions susdites. Poser cette question, c’était enfin inciter les chercheurs à se pencher sur la réalisation des plans d’action. Les contributions réunies dans ce volume abordent ces problèmes à propos de l’enseignement du français en France, en Suisse romande, au Québec, en Belgique francophone et au Liban, de la maternelle à la formation continuée des enseignants.
