En janvier 2009, 27 maisons situées sur le littoral sud du Vietnam, dans la ville de Phan Thiet, zone très touristique à 200 kilomètres à l'est de Ho Chi Minh-Ville, se sont effondrées. Une centaine d'autres bâtiments étaient également menacés de disparition. Les médias internationaux ont ainsi relayé l’information « des centaines de soldats, de gardes côtes et de volontaires ont été mobilisés pour amasser des sacs de sable sur place et tenter de limiter les dégâts. En cause, l'érosion du littoral, grignoté par de fortes vagues. Selon les experts, le Vietnam et ses plus de 3.200 km de côtes font partie des zones les plus exposées aux effets du réchauffement climatique, qu'il s'agisse de l'élévation du niveau des mers ou de l'augmentation de la fréquence des typhons et inondations ». Il s’agit donc indéniablement d’une des conséquences du réchauffement climatique. Cet article montre comment, en utilisant la fonction multi dates Google Earth, il est possible de démonter cette argumentation et de mettre en évidence les vraies causes de ce rapide et inéluctable retrait des côtes au niveau de ce village de pêcheurs, à savoir la construction anarchique de la station balnéaire de Mui Ne, quelques kilomètres à l’est. La création de ce désormais haut lieu touristique est extrêmement récente, le premier établissement étant sorti de terre en 1994. Vu le succès croissant des plages de sable blanc, toute la côte a depuis été lotie sur près de cinq kilomètres. Mui Ne a donc modifié son espace pour accueillir les touristes occidentaux. Ainsi, les cocoteraies ont été abattues pour laisser la place à des cocotiers ne faisant plus office que de décor sur la plage, les liserons des sables ont été arrachés pour éloigner les puces de mer, le sable a été égalisé et les infrastructures hôtelières ont recouvert les dunes pour être en contact direct avec la plage. C’est ainsi tout un décor « exotique » qui est créé pour être conforme aux représentations des touristes occidentaux. La suite est connue d’avance : le fragile équilibre littoral est rompu et le bilan sédimentaire devient négatif. Entre 2006 et 2009, la plage d’une trentaine de mètres a totalement disparu. Or, la plage étant la raison d’être de ce lieu, il convient de la préserver à tout prix. Ainsi, les promoteurs immobiliers ont eu recours à la construction d’épis de plus de 100 mètres pour recréer de longues plages, artificielles cette fois, qui interrompent le transit sédimentaire. La dérive littorale est ainsi stoppée ce qui engendre la disparition des plages suivantes et l’effondrement des maisons de pêcheurs. Cette analyse montre clairement la rapide modification des paysages qui résulte d’une conversion économique locale non encadrée répondant aux processus de mondialisation. [less ▲]

We present in this talk a new linear non-adiabatic pulsation code: MAD[SUP]1[/SUP]. We detail all the possible applications of it in the frame of asteroseismology. By using it, photospheric observables such as multi-color photometric amplitude ratios, phase differences and line profile variations can be determined accurately and confronted with observations. Moreover, MAD enables the precisely analysis of the excitation mechanisms of pulsating stars. Applications to different kinds of variable stars (delta Sct, beta Cephei, Slowly Pulsating B and gamma Dor stars) are presented by Dupret et al. (these proceedings), Handler and Aerts (these proceedings), De Cat et al. (these proceedings) and De Ridder et al. (these proceedings). [less ▲]

For delta Scuti stars, phase differences and amplitude ratios between the relative effective temperature variation and the relative radial displacement can be derived from multicolor photometric observations. The same quantities can be also calculated from theoretical non-adiabatic pulsation models. We present here these theoretical results, which indicate that non-adiabatic quantities depend on the mixing length parameter alpha used to treat the convection in the standard Mixing Length Theory (MLT). This dependence can be used to test and to constrain, through multicolor observations, the way MLT describes convection in the outermost layers of the star. We will use the equilibrium models provided by the CESAM evolutionary code. The pulsational observables are calculated by using a non-adiabatic pulsation code developed by R. Garridon and A. Moya. In the evolutionary and pulsation codes, a complete reconstruction of the non-grey atmosphere (Kurucz models) is included. The interaction between pulsation and atmosphere, as described by Dupret et al. (2002), is also included in the code. [less ▲]

For delta Sct stars, the theoretical predictions of a non-adiabatic pulsation code are very dependent on the characteristics of the thin convective envelope of the models (Balona and Evers 1999). The treatment of the non-adiabatic interaction between convection and pulsation also has a significant impact on the results, particularly near the red edge of the instability strip. The non-adiabatic theoretical predictions can be tested upon observations by comparing them to the amplitude ratios and phase differences as observed in different color passbands (Dupret et al. 2003). In the first part of this paper, we compare the results obtained by adopting different treatments of convection in the interior and atmosphere models: mixing-length theory (MLT) and full spectrum of turbulence (FST) (Canuto et al. 1996, CGM). In the second part, we examine the problem of the interaction between convection and pulsation and compare the mode stability obtained with and without including time-dependent convection in our non-adiabatic code.

The interest in studying multiple systems comes from the fact that they give a good number of constraints on their components. From the multiplicity we have constraints on mass and age. Moreover, if one or more components of the system show oscillating properties as the DG Leo triple system, additional constraints provided by seismology can be obtained once the modes are identified. In this work, we consider an equilibrium model of the DG Leo system constrained by its multiplicity properties, we attempt to check our new Time Depending Convection treatment on the modes identification of the DG Leo system.

Phase differences and amplitude ratios at different colour photometric bands are currently being used to discriminate pulsation modes to facilitate mode identification of kappa-driven non-radial pulsating stars. In addition to physical inputs (e.g., mass, T_eff, etc.), these quantities depend on the non-adiabatic treatment of the atmosphere. This paper presents theoretical results concerning delta Scuti pulsating stars. The envelope of each of these stellar structures possesses a convection zone whose development is determined by various factors. An interacting pulsation-atmosphere physical treatment is introduced which supplies two basic non-adiabatic physical quantities: the relative effective temperature variation and the phase lag phi[SUP]T[/SUP], defined as the angle between effective temperature variation and radial displacement. These quantities can be used to derive the phase differences and amplitude ratios. Numerivalues for these quantities depend critically on the alpha MLT parameter used to calculate the convection in the envelope. The dependence on alpha was analyzed and it was found that the use of colour observations may be of considerable importance in testing the MLT. Finally, examples are given of how alpha introduces uncertainties in the theoretical predictions regarding phases and amplitudes of photometric variations in delta Scuti pulsating stars. [less ▲]

Non-alcoholic steatohepatitis (NASH) is a disease of emerging identity and importance, and is now considered as one of the commonest liver diseases in western countries. It is frequently associated with severe obesity, especially abdominal adiposity, and is intimately related to various clinical and biological markers of the insulin resistance syndrome. Especially, both the prevalence and the severity of liver steatosis are related to male sex, body mass index, waist circumference, hyperinsulinaemia, hypertriglyceridaemia and impaired glucose tolerance or type 2 diabetes. A substantial weight loss following gastroplasty is accompanied by a marked reduction in the prevalence and the severity of the various biological abnormalities of the metabolic syndrome and, concomitantly, by an important regression of liver steatosis in most obese patients. However, in some patients, this rapid and drastic weight loss may result in a mild increase in inflammatory lesions (hepatitis), despite the regression of steatosis, which might result from the rapid mobilization of fatty acids or cytokines from adipose tissue, especially visceral fat. The intimate relationship between NASH and obesity leads to the concept that NASH may be considered as another disease of affluence, as is the insulin resistance syndrome and perhaps being part of it.
