This work reports on the influence of -lactoglobulin (β-LGB) and of its denaturation on the adherence of quartz particles, taken as a model of particulate soil, on stainless steel AISI 304 with mirror finish. The substrate was soiled with quartz suspensions in water or in β-LGB solutions as such or previously heated at 75°C, and dried at room temperature or in an oven at 75°C. Cleanability was evaluated after exposure to water in a radial flow chamber. Auxiliary characterizations were the surface tension and protein concentration of the solution, surface analysis of the substrate by X-ray photoelectron spectroscopy (XPS) and contact angle measurements. The contact of stainless steel with -LGB led to adsorption of the protein, which dominated the composition of the organic layer with respect to contaminants initially present, and was not markedly desorbed upon rinsing. The presence of β-LGB at the quartz particle/substrate interface slightly increased the adherence, which was further increased when the protein was denatured. On the other hand, denaturation of -LGB enhanced its surfactant effect at the water/air interface. Comparison with systems investigated before suggests that the influence of protein via droplet spreading and soiling particles aggregation may be of minor importance compared to direct effects on the substrate/quartz interface. Stainless steel does not behave as a hydrophilic substrate owing to its surface contamination with organic compounds. It appears suitable to examine the influence of the initial surface state of stainless steel on its behavior regarding soiling and cleaning. [less ▲]

Recent technology reviews have identified the need for objective assessments of aircraft engine health management (EHM) technologies. To help address this issue, a gas path diagnostic benchmark problem has been created and made publicly available. This software tool, referred to as the Propulsion Diagnostic Method Evaluation Strategy (Pro- DiMES), has been constructed based on feedback provided by the aircraft EHM community. It provides a standard benchmark problem enabling users to develop, evaluate, and compare diagnostic methods. This paper will present an overview of ProDiMES along with a description of four gas path diagnostic methods developed and applied to the problem. These methods, which include analytical and empirical diagnostic techniques, will be described and associated blind-test-case metric results will be presented and compared. Lessons learned along with recommendations for improving the public benchmarking processes will also be presented and discussed. [less ▲]

Les collines cuprocobaltifères du Katanga sont des lieux privilégiés pour étudier la variation des traits fonctionnels le long de gradients de stress métallique. Nous avons étudié la variation de six traits à l’échelle des espèces et de la communauté le long d’un gradient de cuivre et cobalt. D’autres paramètres tels que la concentration en phosphore et l’humidité du sol covarient positivement avec la teneur en métal du sol. Les contributions relatives du remplacement d’espèces et de la variabilité intraspécifique à la variabilité totale des traits dans les communautés ont été déterminées. A l’échelle de la communauté, la hauteur et la surface foliaire diminuent alors que les valeurs des quatre autres traits augmentent le long du gradient. Les espèces montrent des réponses variées, généralement non significatives. Pour tous les traits, le remplacement d’espèce est le moteur principal de la variation au sein des communautés. La concentration en métal du sol implique des réponses variées sur les différents traits et les différentes espèces. Nous montrons que la concentration croissante en métal privilégie le remplacement d’espèce par rapport à la variation intraspécifique et que les espèces répondent par différentes stratégies de tolérance à la concentration en métal du le sol. La variation des traits à l’échelle des communautés est essentiellement le reflet d’un changement dans les abondances des différentes formes de vie. Les espèces à xylopodes sont dominantes sur sol pauvre en métal alors que les annuelles sont dominantes sur sol très enrichi. [less ▲]

Ecomorphology is the study of the relationships between functional design and the environment. One of its aims is to understand how the environmental factors can constraint the performance of an organism or act on its phenotype. Different studies have already showed in different cetaceans that the number and shape of vertebrae can reflect the stiffness of the body and consequently can impact their swimming mode. The aim of this preliminary study is to establish relationships between characteristics of the vertebral column of different cetaceans and their ecology. To this purpose, we have studied meristic and morphometric data on the vertebrae (centrum length, height and width, neural and haemal spine height and the transverse process length) of different species of mysticetes and odontocetes coming from the Aquarium-Museum of Liège and Royal Institute of Natural Sciences of Bruxelles. Preliminary results showed the distinction of three morphotypes: firstly, the active, cruising, fast swimmers with rigid body, secondly, the maneuverers, slow swimmers with flexible body and thirdly, the steady swimmers.
