In this article, we go back on two ways of taking into account the environmental dimension in urban planning and governance. We stress the difficult articulation between these two approaches – “urban ecology” and “urban environment” – and the actual impasse the discipline of urban planning finds itself in in its quest of the sustainable city. These two approaches for acting on the city by considering the complexity of its milieu build on different representations of this milieu and different modes of action legitimation. Negating each other, they can difficultly coexist, even less articulate. Through the example of water management in Cochabamba, we stress the tensions between these approaches. We point also to the awkward and marginalized position of urban planning and challenges it must face to regain a capacity of action in contemporary fragmented cities that know complex governance landscapes and rare or endangered resources.

In the economic and energy context of our society, it is universally recognized that alternatives to petrochemicals products must be found. To overcome this problem, renewable lignocellulosic biomass could be used to produce high value products. To achieve this objective, pretreatment processes are required to allow the breakdown of lignocellulosic structure and increase accessibility of the material. In this way, steam explosion is a thermo-mechano-chemical pretreatment which allows the opening of lignocellulosic material structural components and includes modifications of the physical properties of the material, hydrolysis of hemicellulosic components and modification of the chemical structure of lignin [1]. This study is focused on the impact of various steam explosion treatments on the chemical configuration of tall fescue lignin. NMR analyses perform on the Festuca L. pretreated samples show variations of links with treatment intensity. Observations show double phenomen :re-polymerization and depolymerization of the lignin structure during steam explosion process [2]. In parallel, HPSEC analyses show modifications in the molecular weight of the lignin obtained after the steam explosion treatment. [less ▲]

Massive stars are the progenitors of the most energetic explosions in the Universe such as core-collapse supernovae (CCSNe) and gamma ray bursts. During their life time they follow various evolutionary phases (e.g. supergiant, luminous blue variable and Wolf-Rayet). They strongly influence their environments through their energetic ionization radiation and powerful stellar winds. Furthermore, the formation of low- and intermediate-mass stars are also being regulated by them. The Carina nebula region, which hosts a large population of massive stars and several young star clusters, provides an ideal target for studying the feedback of massive stars. In this thesis, we investigated a wide field (32′ × 31′ ) region located in the west of the Carina nebula and centered on the massive binary WR 22. For our study, we used new optical photometry (UBVRI Hα), along with some low resolution spectroscopy, archival near infra-red (2MASS), and X-ray (Chandra, XMM-Newton) data. We estimated several parameters such as reddening, reddening law, etc. and also identified young stellar objects located in the region under study (Kumar et al., 2014b). Among the various types of CCSNe, Type IIb are recognized with their typical observational properties. Some of them show clear indication of double peaks in their light curves. The spectral features of these SNe show a transition between Type II and Type Ib/c events at early and later epochs, respectively. It has been noticed that the occurrence of these events is not common in volume limited surveys. In this thesis we have studied the properties of the light curve and spectral evolution of the Type IIb supernova 2011fu. The observational properties of this object show resemblance to those of SN 1993J with a possible signature of the adiabatic cooling phase (Kumar et al., 2013). When light passes through the expanding ejecta of the SNe, it retains information about the orientation of the ejected layers. In general, CCSNe exhibit a significant level of polarization during various phases of their evolution at different wavelengths. We have investigated the broad band polarimetric properties of a Type II plateau SN 2012aw and compared it with other well-studied CCSNe of similar kinds (Kumar et al., 2014a). In the framework of the present thesis, we have also contributed to the development of the 4m International Liquid Mirror Telescope (ILMT) project which is a joint collaborative effort among different universities and research institutes in Belgium, India, Canada and Poland. We performed various experiments including the spin casting of the primary mirror, optical quality tests of the mercury surface, mylar film experiments, etc. The possible scientific capabilities and future contri- butions of this telescope are also discussed. We propose our plans to identify the transients (specially supernovae) with the ILMT and their further follow-up scheme. The installation of the ILMT will start very soon at the Devasthal observatory, ARIES Nainital, India. [less ▲]

SOLAP (Spatial OnLine Analytical Processing) is a server which allows decision makers to quickly analyze archived data from a spatial datawarehouse. Until now, most of SOLAP tools only manage spatial data through the vector mode. However, some visualization techniques use interpolation to transform them into continuous fields in raster mode. Crime hotspot mapping is one of them: data are modeled in raster with a KDE (Kernel Density Estimation) algorithm to offer a spatially continuous visualization of crimes. This research aims at combining hotspot mapping and SOLAP. First, we adapt SOLAP to continuous fields with a raster multidimensional data model. Then the raster model is adapted to KDE. The data model is validated with a prototype including London crime data. [less ▲]

As used by Egyptians for irrigation and reported by Archimedes, a screw turning inside a hollow pipe can pull out a fluid againt gravity. At a centimetric scale, an analagous system can be found with a drop pending on a rotating spiral which is tilted toward the horizontal. The ascent of the drop to the top of the spiral is considered and a theoretical model based on geometrical considerations is proposed. The climb of the drop is limited by the fluid deposition on the screw at high capillary number and by a centrifugation phenomenon. We find out the range of fluid proprities and spiral characteristics for which an ascending motion of the drop is possible. Finally we discuss the efficiency of such system to extract a fluid from a bath at a centrimetric scale. [less ▲]

Cette étude exploratoire vise à examiner les variables corrélées aux attitudes positives et négatives à l'égard du mariage (SSM) et des parents de même sexe (SSP) dans trois pays (France, Belgique, Italie) où les personnes LGBT possèdent au moment de l’étude (2012-2013) différents niveaux de reconnaissance de leurs droits civils et parentales. Les attitudes ont été évaluées à travers de questionnaires en ligne chez une cohorte de 11180 participants s’auto-déclarant hétérosexuels résidants en Belgique, France et en Italie : 53% de femmes, 47% des hommes âgés de 18 à 25. Nous avons supposé que les attitudes positives envers les SSM et SSP seraient associées au sexe féminin, à une faible religiosité, à une idéologie politique libérale et à des autres variables comme le contact avec les personnes LGBT. Les résultats confirment que certaines variables sociodémographiques ainsi que le contact et la satisfaction relationnelle avec les personnes LGBT s’associent aux attitudes positives ou négatives. En particulier une plus grande satisfaction dans les relations avec les personnes LGBT s’associe à des attitudes plus positives envers les personnes LGBT en général, le mariage homosexuel et l’homoparentalité. La qualité de la relation semble être plus importante que la quantité dans la prédiction des attitudes positives. Limitations: Les étudiants qui ont participé à l’étude ne sont pas représentatifs de la population générale dans les trois pays. Ils n’ont pas été choisis au hasard parmi toutes les universités de chaque pays, de telle sorte les résultats ne sont pas généralisables à tous les étudiants. [less ▲]

We investigated how physical incorporation, brine dynamics and bacterial activity regulate the distribution of inorganic nutrients and dissolved organic carbon (DOC) in artificial sea ice during a 19-day experiment that included periods of both ice growth and decay. The experiment was performed using two series of mesocosms: the first consisted of seawater and the second consisted of seawater enriched with humic-rich river water. We grew ice by freezing the water at an air temperature of -14 °C for 14 days after which ice decay was induced by increasing the air temperature to -1 °C. Using the ice temperatures and bulk ice salinities, we derived the brine volume fractions, brine salinities and Rayleigh numbers. The temporal evolution of these physical parameters indicate that there was a succession of 3 stages in the brine dynamics: forced-convection, followed by bottom convection during ice growth, and then brine stratification during ice decay. The major findings are: (1) the incorporation of dissolved compounds (nitrate, nitrite, ammonium, phosphate, silicate, and DOC) into the sea ice was not conservative (relative to salinity) during ice growth. Brine convection clearly influenced the incorporation of the dissolved compounds, since the non-conservative behavior of the dissolved compounds was particularly pronounced in the absence of brine convection. (2) Bacterial activity further regulated nutrient availability in the ice: ammonium and nitrite accumulated as a result of remineralization processes, although bacterial production was too low to induce major changes in DOC concentrations. (3) Different forms of DOC have different properties and hence incorporation efficiencies. In particular, the terrestrially-derived DOC from the river water was less efficiently incorporated into sea ice than the DOC in the seawater. Therefore the main factors regulating the distribution of the dissolved compounds within sea ice are clearly a complex interaction of brine dynamics, biological activity and in the case of dissolved organic matter, the physico-chemical properties of the dissolved constituents themselves.

What is the phenomenal structure of our perceptual experiences? In this talk, I suggest that perceptual experiences – like consciousness in general – have a mereological structure, that is, a structure in which the most basic relation is that of parthood. I do not provide any definitive argument for this view. I just want to suggest (i) that the mereological approach is untouched by the usual objections coming from the proponents of the Unified Field Theory (James, Searle, Tye), (ii) that the Unified Field Theory faces some important difficulties of its own.

de l’avion en vol. Mieux, on peut montrer que la position du centre de gravité (qui dépend du chargement de l’avion) affecte la consommation de carburant. Ce résultat revêt une importance majeure dans un contexte d’augmentation des prix du pétrole et où il s’agit de réduire les émissions polluantes. Pour un transport aérien plus économique, il s’agit aussi, en cas de livraisons à différents endroits, de réduire au maximum les temps de chargements et de déchargements afin de limiter les coûts liés aux paiements des salariés et à l’utilisation de chaque aéroport intermédiaire. Au cours de mon exposé, je présente un modèle mathématique qui vise à trouver le chargement qui minimise la consommation de carburant et les temps de chargements et déchargements. Je partage avec nous les résultats de mes recherches dont les applications garantissent un impact écologique et économique positif. [less ▲]

Methanol (CH3OH) is the second most abundant organic compound in the Earth's atmosphere after methane. In this work, we present the first long-term time series of methanol total, lower tropospheric and upper tropospheric-lower stratospheric partial columns derived from the analysis of high resolution Fourier transform infrared solar spectra recorded at the Jungfraujoch station (46.5° N, 3580 m a.s.l.). The retrieval of methanol is very challenging due to strong absorptions of ozone in the region of the selected υ8 band of CH3OH. Two wide spectral intervals have been defined and adjusted in order to maximize the information content. Methanol does not exhibit a significant trend over the 1995–2012 time period, but a strong seasonal modulation characterized by maximum values and variability in June–July, minimum columns in winter and a peak-to-peak amplitude of 130%. In situ measurements performed at the Jungfraujoch and ACE-FTS occultations give similar results for the methanol seasonal variation. The total and lower tropospheric columns are also compared with IMAGESv2 model simulations. There is no systematic bias between the observations and IMAGESv2 but the model underestimates the peak-to-peak amplitude of the seasonal modulations. [less ▲]
