Recent studies on the respective contribution of GABAA receptor subunits in the various pharmacological effects of benzodiazepines suggest that the sedative and amnesic properties of diazepam are mediated by enhancement of gabaergic transmission in neurons expressing the alpha 1 subunit while the anxiolytic effect is selectively mediated by alpha 2 subunit. These findings suggest that a separation of the pharmacological properties of benzodiazepines is possible and that drugs with increased clinical specificity could be developed. [less ▲]

The present paper describes the major results obtained from 1989 to 1992 by the EUROMODEL group in studying the circulation in the Western Mediterranean Sea. Particular emphasis has been given to the physical processes responsible for seasonal and mesoscale variabilities. Observations (in situ and satellite), together with theoretical, physical and numerical models, have been widely used in the course of these studies. Attention has been focused on the dynamics of the northern basin (deep water formation, dynamics of the Northern Mediterranean Current, circulation and shelf/slope interaction in the Balearic Sea) and of the southern basin (Alboran Sea circulation, instabilities of the Algerian Current). The straits dynamics have been studied with particular reference to the Corsica channel. Preliminary runs of a basin-scale circulation model of the Western Mediterranean Sea forced by the straits are also presented. They are shown to be capable of generating a cyclonic circulation in the western basin. [less ▲]

With the goal to study crack propagation in continuous casting, this paper presents an on going project to develop and identify a mathematical finite element model of damage in steel at high temperature. A representative microscopic cell of the material is presented and adapted to available chemical information, precipitation state and micro-structures observed using metallographic as weel as imaging methods (optical microscopy, SEM, orientation imaging microscopy). Compression tests of cylindrical samples after a thermal treatment have been performed to identify the parameters of an elasto-visco-plastique law of Norton-Hoff type. Hot damage tests in tensile and compression states help to provide information on crack appearance. [less ▲]

The milk fat globule is essentially an oil droplet enclosed in a protective 'membrane', partially derived from the plasma membrane of the lactating cell, and which assures the dispersion of the milk fat in the milk plasma. This protective coat is generally called 'the milk fat globule membrane' (MFGM). This review examines the present state of knowledge on the MFGM. The topics dealt with are: origin and formation, isolation From milk, composition (lipids and proteins), structure (a new model is proposed), functional properties and the role that the MFGM plays in protection against lipolysis.

Hot subdwarf stars, including helium core burning subdwarf B (sdB) stars and more evolved subdwarf O (sdO) stars, host three classes of nonradial pulsators. Two of them show rapid acoustic mode oscillations (with periods in the 60-600 s range), while the third class features slow gravity mode vibrations of period typically 1h. All three classes provide a strong potential for sounding the internal properties of stars in these evolved phases of stellar evolution through asteroseismology. This has so far been exploited mainly for the rapid p-mode sdB pulsators, but the long period g-mode sdB pulsators, with the advent of space observations, carry good promises for sounding even deeper regions inside these stars. In this review paper, we summarize the properties of pulsating hot subdwarf stars and we outline progress that have recently occured in the asteroseismic exploitation of the pulsations observed in sdB stars.

The hot pulsating sdB star PG 1605+072 exhibits uncommon spectroscopic and pulsation prop- erties, and is one of the biggest challenge in the field of sdB star modeling. Two hypotheses have been proposed to explain its unusually rich pulsation spectrum. The first is the natural explanation of a fast-rotating pulsator, which lifts the (2l+1)-fold degeneracy of the frequency components. Another approach, where PG 1605+072 can be seen as a slow rotator, considers that the numerous low amplitude frequency components are second- and third-order harmonics and nonlinear com- binations of the highest amplitude frequencies. We investigated the two hypotheses in the light of asteroseismology, using our latest tools - including pulsation codes that incorporate star rotation and new generation complete sdB models. The results of both approaches are presented, showing interesting results and raising new questions for our understanding of this mysterious sdB star. [less ▲]

This paper presents various works completed by the laboratory SURFACES - Department of Geomatics, University of Liege - between 1994 and 2000 in the framework of the TELSAT programme. Not less than 22 studies have been achieved during this period, which mainly deal with the use of very high resolution (VHR) satellite imagery and urban remote sensing. Owing to the experience accumulated about these topics by the laboratory for the beginning of the TELSAT programme - in the mid of the '80s - the works here under consideration are mainly devoted to applied studies. However fundamental research is not withdrawn. The expectation — and recently the availability — of new sensors was the opportunity for simulating, developing and improving methods, notably in the domains of the fusion of images and satellite photogrammetry. Finally it is worth noting that, as far as our laboratory is concerned, the considered period is also characterized by a wide diffusion of the results of our researches in fundamental and applied remote sensing. Several books and many papers have been published while an international symposium was held in Liege dedicated to urban remote sensing. On the other hand, satellite maps. CD and Web sites have been largely distributed for vulgarisation purposes. [less ▲]
