The consequences of sarcopenia on quality are difficult to evaluate and consequently are quite poorly studied. The few studies assessing the quality of life in sarcopenic subjects currently use generic quality of life questionnaires such as SF36 and EQ5D. The SarcoPhAge study, conducted on a cohort developed in Liège including 534 subjects of 65 years or older, suggested that sarcopenic subjects present a significant worse quality of life in the domains of physical function compared to nonsarcopenic subjects. Generic tools do not cover exhaustively all the areas of potential dysfunction concerned in this geriatric syndrome. Yet, there is no specific and validated quality of life questionnaire for sarcopenia. It would be useful to have at our disposal a sarcopenia specific quality of life questionnaire to assess not only the prospective quality of life of sarcopenic subjects but also to assess the efficacy and the rele [less ▲]

Ceramic clays are one of the most complicated ceramic systems because of the very complex relationship between the behavior of minerals during the ceramic processing and the transformations during heating. A major challenge is to predict the phase transformations in clay ceramics. The aims are to establish reference data of ceramics products that can be formed based on the mineralogical composition of the local raw materials. These data, in turn, can be compared with the archaeological ceramics in order to study their origins. The mineralogical compositions and transformations during the firing (550 to 1100ºC under oxidizing conditions) of seven clayey materials sampled from the main clay deposits of Northern Morocco were evaluated by X-ray powder diffraction. Two groups of clays were evidenced according to the type of neoformed high-temperature minerals: non-calcareous clays and calcareous clays. For the non-calcareous raw materials, spinel is produced at 950°C. Cristobalite and mullite were formed above 1000ºC from clays that contain illite, kaolinite and chlorite. In clays containing vermiculite and high amount of chlorite, hematite was formed from 950°C. Firing of calcareous clays at temperatures > 950ºC yielded Ca-silicates (diopside, gehlenite and wollastonite), spinel, cristobalite, hematite and feldspars. Mullite may also form in the calcareous clay products, when the carbonates content exceeds 10%. [less ▲]

Studies dealing with quantitative decline of freshwater fish species with long-time series data are rather scarce and primarily limited to migratory species. We present an original work integrating over two decades investigations on roach (Rutilus rutilus L.) stock, one of the dominant cyprinid fish species in the River Meuse (Belgium). This study aimed to quantify changes in the stock of roach after recent indicators (captures from sport fishermen) suggested a sharp decline. Three methods were used: capture-mark-recapture (CMR) estimation, catch per unit of effort by gillnetting (CPUE) and long-term monitoring of fish-passes. Population dynamics of roach was also investigated. CMR method demonstrated a decrease of 91% of the roach stock compared to earlier data (1993–2003), with current densities close to 300 roach ha–1. This was also confirmed by a decrease of 95 % in CPUEs and a decrease between 93 and 98 % in two fish-passes during the same period. On the other hand, growth and mortality did not indicate radical changes before and after the decline was found. As roach stock decline is generalizable to the whole Belgian’s Meuse following estimations in two other sites, further investigations are needed to explain the reasons underlying this decline in order to take conservation measures. First, the uptake of primary production (i.e. phytoplankton) by invasive clams is supposed. And secondly, an increase in predation pressure by the Great Cormorant is effective as this avian predator was found in high densities from 2000 until 2006. [less ▲]

Resilience of organisms after threat removal is an essential feature to justify conservation efforts. Amphibians are particularly threatened with a worldwide decline, showing a low resistance to invaders such as fish. Previous research has shown that they could recover after fish extirpation due to metamorphosed colonizers. However, not all amphibian phenotypes are able to persist to fish introduction and disperse. In many species of newts and salamanders, paedomorphs retain gills in the adult stage, which makes them fully aquatic. A proposed way to conserve this phenotype would be to remove introduced fish from their habitats. However, because paedomorphosis is usually not expressed in the presence of fish, it is unknown whether fish removal could allow the resilience of paedomorphs. This would be possible only if progenies of metamorphosed individuals could become paedomorphic in restored habitats. Through a quantitative survey in three types of ponds, including control ponds without fish, ponds in which fish were extirpated, and fish ponds, we determined abundances of paedomorphic and metamorphic palmate newts (Lissotriton helveticus). The results show that paedomorphosis resilience is possible and even highly frequent, as paedomorphs were found in 80% of ponds where fish disappeared. Abundances were similar between these ponds and control ponds whereas fish ponds had almost no newts, indicating a very low resistance to invaders. This shows that conserving common phenotypes can help to preserve endangered phenotypes, as paedomorphs were produced through the reproduction of metamorphs. There is thus hope of maintaining intraspecific biodiversity though conservation action involving threat removal. [less ▲]

For more than 25 years now, traceroute has demonstrated its supremacy for network-path measurement, becoming the most widely used Internet path diagnosis tool today. A major limitation of traceroute when the destination is not controllable by the user is its inability to measure reverse paths, i.e., the path from a destination back to the source. Proposed techniques to address this issue rely on IP address spoofing, which might lead to security concerns. In this paper we introduce and evaluate DisNETPerf, a new tool for locating probes that are the closest to a distant server. Those probes are then used to collect data from the server point-of-view to the service user for path performance monitoring and troubleshooting purposes. We propose two techniques for probe location, and demonstrate that the reverse path can be measured with very high accuracy in certain scenarios. [less ▲]

Ces matériaux se sont formés dans des milieux variés, souvent des mers peu profondes et sont les témoins de près d’un demi-milliard d’années d’histoire de notre région! Cette richesse géologique représente aussi une fabuleuse richesse archéologique et patrimoniale dans l’utilisation exceptionnellement variée qui en a été faite, depuis l’époque romaine jusqu’à nos jours. Donner à chacun l’occasion d’identifier et de comprendre ces pierres et marbres est le but de ce livre. [less ▲]
