Research interest in the thermo-mechanical behaviour of unsaturated soils is growing as a result of an increasing number of geomechanical problems involving both thermal and unsaturated effects. A new constitutive model dealing with partially saturated soils under non-isothermal conditions is presented through a unified and highly coupled constitutive approach. In the context of the elasto-thermoplasticity and the critical state theory, the so-called ACMEG-TS model uses the concepts of multi-mechanism and bounding surface theory. The generalized effective stress framework is adopted to represent the stress state in the soil. This model brings advancements on the thermo-hydraulic couplings that directly affect the mechanical behaviour of the materials. The constitutive relations based on the evolutions of the two key parameters (the reconsolidation pressure and the air-entry suction) make it possible to reproduce the main features of the thermo-mechanical behaviour of unsaturated soils. Theoretical aspects of the paper are supported by comparisons between numerical simulations and experimental results extracted from literature. [less ▲]

The quality valuation of wheat is based on characteristics like yield, specific weight, protein content and protein quality. Until now. the starch properties are rarely considered as a quality criterion. In this study, we showed the influence of wheat cultivars (Triticum aestivum L.) and culture year on the intrinsic properties of starch, extracted from European wheat grown in the same conditions. For example, starch damage varied from 13.2 to 19.9 CDU in function of the cultivars and contribution of the B-type starch granules (<10 mu m) to the total volume ranged from 11.6% to 29.9%. Starch viscosity at 95 degrees C, characterized with alpha-amylase inactivation by 2 mM AgNO3 addition. varied from 276.5 to 351.5 BU with the wheat cultivars. It is apparent from this study that starch properties were principally influenced by the wheat cultivar and slightly by the culture year. A good relationship between the pasting properties of whole flour and starch were finally established, showing the important role of starch in the whole flour viscosity. A thorough working knowledge of starch properties could lead to an appropriate selection of wheat cultivar, well-adapted to industrial end uses, without encountering processing or end-products quality problems and with most cost-competitive production.

Aias, herausragender griechischer Heros vor Troia, metzelt im Zustand der Raserei Herdenvieh nieder, in dem er seine Gegner zu erkennen glaubt. Zur Besinnung gekommen, stürzt er sich, beschämt über den Ehrverlust, in sein Schwert. Die ‚Entschuldigung‘, die für Aias nur durch Entleibung zu leisten war, entspricht heute etwa dem medial inszenierten Rückzug aus der politischen Öffentlichkeit, dem Rücktrittsangebot oder dem Fehlereingeständnis. Offensichtlich gibt es nach wie vor ein kollektives Bedürfnis nach solchen stellvertretenden Reinigungsritualen. Anlässe und Reaktionsformen haben sich zwar gewandelt, das Gefühl der Scham aber ist immer noch von existenziell-individueller Bedeutung und besitzt eine öffentlich wirksame Symbolik. Historisch gesehen spannt der Band einen Bogen von der (laut Georg Wilhelm Friedrich Hegel) ‚gewissenlosen‘ griechischen Antike bis in die ‚unverschämte‘ Gegenwart. Systematisch betrachtet konfrontieren die unterschiedlichen Kulturkreise einander in ihren Definitionen und Kompensationen von Fehlverhalten: vom paganen Griechentum über das christliche Abendland bis hin zum Islam. Im 20. und 21. Jahrhundert bestimmen Diskurse der Bewältigung den Umgang mit der Geschichte, mit Fragen der Kriegsschuld oder des Völkermordes. Kulturelle, nationale, historische und gender-spezifische Unterschiede prägen die verbalen Entschuldigungen, das öffentliche und private Verhalten, Kleidercode und Körpersprache. Während Schamdiskurse dazu dienen, eigenes Fehlverhalten in der Gemeinschaft zu regulieren oder vor dem Selbst zu rechtfertigen, funktionieren umgekehrt Schuldzuschreibungen oder gezielte Beschämungen des anderen als Herrschaftsinstrumente: prominent etwa in den Bildern von Abu Ghraib.

Structures and ontogeny of schools in two cichlid fishes: quantitative approach with computerized videotracking systems in Oreochromis niloticus and Pelvicachromis pulcher. by Johann DELCOURT (Behavioural Biology Unit, Ethology and Animal Psychology, University of Liège, Belgium) The research works presented in this thesis, using new ethometric techniques based on digital imaging analysis, concerns several questions relating to the study of shoaling and schooling behaviours in early stages of life in two Cichlid species. Our two model species, the Nile tilapia (Oreochromis niloticus L.) and Pelvicachromis pulcher, are respectively a mouthbreeder and a substrate breeder. These reproductive and parental strategies have a direct impact on the ontogeny of fry. In this study, we have worked at understanding the impact of these strategies on the ontogeny of shoaling and schooling behaviours. The characterization of these behaviours needed the elaboration of new videotracking systems able to track individually a large number of fish, and the analysis of the spatial and dynamical structure of the group. After an extensive general introduction devoted to the shoaling and schooling behaviours in regards of the ethological study plan, we present our works in three major goals. These three topics concern: 1. Lab works using some classical methods of direct observation and a technique of computerised vision systems (Ethovision®). Moreover, Laboratory studies of fish groups were conducted to develop a new multitracking system, in collaboration with the G.R.A.S.P. (ULg), able to track a large number of unmarked individuals (up to 100 fishes) during several minutes. Thanks these two tracking systems, we studied the fry behaviours at the individual and the groups levels. 2. The emergence conditions of these behaviours. Are the fry able to adopt these behaviours in absence of parents, in absence of external stimuli? In this context, we described the spatial and dynamical (local and global) structures of groups to understand the mechanisms allowing the existence of schools. 3. The ontogeny of shoaling and schooling behaviours in the two model parental species. The first part exposes research devoted to the application, development and validation of the use of two videotracking systems (presented in the material and methods section). The advantages, capacities and limits of these systems are presented. The work concerning the emergence (the mechanisms) and the ontogeny are presented in scientific paper format in the “Results” section. A large general discussion centred on the three major goals (development of new ethometric tools, the structures and mechanisms of schools and the ontogeny of shoaling and schooling behaviours) concludes this PhD dissertation.

The deformation and 40Ar-39Ar dating of recent volcanism that remarkably sits across the North Anatolian Fault eastern termination in Turkey, together with previous studies, put strong constraints on the long- term evolution of the fault. We argue that after a first phase of 10 Ma, characterized by a slip rate of about 3 mm/yr, and during which most of the trace was established, the slip rate jumped to about 20 mm/yr on average over the last 2.5 Ma, without substantial increase of the fault length. The transition correlates with a change in the geometry at the junction with the East Anatolian Fault that makes the extrusion process more efficient. [less ▲]

Fe/SiO2 catalysts have been prepared by two different sol-gel methods, cogelation and dissolution. The cogelation and dissolution preparative methods lead to xerogels with fundamentally different pore width distributions. The nature of the iron species obtained has been examined in detail by UN-visible and Mossbauer spectroscopy, and magnetic, transmission electron microscopy, and X-ray diffraction studies. There is no evidence for the presence of any ordered iron(III) oxides in the samples but all three contain two types of iron species, specifically paramagnetic high-spin iron(III) ions isolated in silica and iron(III) containing nanoparticles with a broad width distribution centered on 1.5 nm, nanoparticles that contain antiferromagnetically coupled clusters of a few ligated bridged iron(III) ions.

Due to their kinetic and substrate specificities, triacylglycerol acyl-hydrolases or lipases are atypical enzymes. In function of their microenvironment, lipases are able to act as hydrolases in aqueous solution or as biocatalysts in organic synthesis. As hydrolases, they are responsible of the triglycerids catabolism into fatty acids and glycerol. In many organisms, this reaction plays a major role in the fat and lipid metabolism. In addition, lipases are also able to hydrolyse phospholipids and cholesterol esters. In organic solvent, lipases could catalyse reactions such as esterifications, acidolysis or alcoolysis with enantio-, regio- and chimioselectivity. Lipases form a mixed class of enzyme due to their animal, vegetal or microbial origins. All those properties led to the development of many applications in the food and chemical industries but also in the medical and therapeutic field. [less ▲]
