This work involves the experimental investigation of flow patterns, preferential regions of deposition and trapping efficiency in rectangular shallow reservoirs. The main flow patterns that can be encountered in rectangular shallow reservoirs are described: symmetrical flows without any reattachment point (S0), asymmetrical flows with one reattachment point (A1), and asymmetrical flows with two reattachment points (A2). The influence of geometrical and hydraulic parameters on reattachment lengths is intensively investigated. A shape parameter is introduced to classify symmetrical and asymmetrical flows. For each flow pattern, the preferential regions of deposition are studied. To conclude, a number of practical recommendations are given. Reservoirs with a shape parameter lower than 6.2 limit sediment deposition. Reservoirs with a shape parameter greater than 6.8 are favourable for sediment deposition. Finally, perspectives for maximizing and minimizing deposition are given, respectively by exploiting the great trapping potential of the flow pattern A1 and the poor trapping potential of the flow pattern S0.

The aim of this study was to develop tocol derivatives of chitosan able (i) to self-assemble in the gastrointestinal tract and (ii) to enhance the solubility of poorly soluble drugs. Among the derivatives synthesized, tocopherol succinate glycol chitosan (GC-TOS) conjugates spontaneously formed micelles in aqueous solution with a critical micelle concentration of 2 μg mL−1. AFM and TEM analysis showed that spherical micelles were formed. The GC-TOS increased water solubility of 2 model class II drugs. GC-TOS loading efficiency was 2.4% (w/w) for ketoconazole and 0.14% (w/w) for itraconazole, respectively. GC-TOS was non-cytotoxic at concentrations up to 10 mg mL−1. A 3.4-fold increase of the apparent permeation coefficient of ketoconazole across a Caco-2 cell monolayer was demonstrated. Tocol polymer conjugates may be promising vehicles for the oral delivery of poorly soluble drugs. [less ▲]

While Jhumpa Lahiri’s work might be thought of as one of the most emblematic instances of the popularity of today’s Indian-American diasporic literature, it remains that its hyper-visibility coincides with an odd form of critical invisibility. This is not to say that critical interventions on Lahiri’s three books have been nonexistent, nor could they have been in view of the fact that the author won the Pulitzer Prize in 2000 for her first collection of short-stories, Interpreter of Maladies. But the vast majority of these readings takes as its premise that view that cultural assimilation and hybridity are still valid notions to investigate narratives focusing on members of the second generation, even as these descendants of migrants consider themselves Indian simply by virtue of their parents, so that they can only claim a second-hand knowledge of migration. Ignoring the difference between first and second-generation Indian-American diasporic experiences – and, what is more, overlooking the fact that the offspring of migrants, unlike their parents, “[do] not really have any other place [than the U.S.] to call home” (Lahiri) – such critical consensus ignores important aspects of Gogol’s complex trajectory in The Namesake. Worse, it proves highly unsatisfactory when it comes to discussing Lahiri’s recent collection of short stories, Unaccustomed Earth, in which the second generation’s accession to early middle age calls into question various preconceptions on heritage and transmission. Can it be then that what is passed on from one generation to the next organizes itself less around positive, than negative entities, that is, around categories such as the gap, the absent, and the unsaid? Taking its cue from Vijay Mishra’s understanding of the diasporic subjectivity in terms of an impossible mourning, my dissertation examines the ways in which Lahiri redefines the notions of belonging and arrival as regards the Indian-American second generation not in terms of cultural assimilation – which would hardly make sense for characters who were born in the U.S. in the first place – but in terms of a re-symbolization of the gaps in the parents’ migrant narratives, more particularly in terms of the “phantom loss” haunting transgenerational relationships between migrants and their offspring. While investigating the figures of emptiness, spectrality, and the message, my dissertation takes various psychoanalytic theories by Sigmund Freud, Julia Kristeva, Nicolas Abraham, Maria Torok and Jean Laplanche, among others, as its major methodological tools. As against a critical consensus that overemphasizes matters of culture, such theoretical framework aims to revaluate the power of the literary in Lahiri’s work. Although this dissertation extends, at times, to Lahiri’s three books, its four chapters boil down to a close reading of the three texts constituting the “Hema and Kaushik” trilogy, which also form part 2 of Lahiri’s 2008 collection of short stories, Unaccustomed Earth. Through these three narratives, which all traffic with the dead-mother metaphor, Lahiri can be seen to inscribe the dimension of mourning at the heart of her approach to “generational arrival.” The three short stories of “Hema and Kaushik” indeed bring to the fore some unacknowledged facets of the much-idealized diasporic experience, which forces us to revise the cultural scenarios through which today’s contemporary world constructs, even essentializes, the figure of the migrant as an emblem of ultimate freedom. My close reading of “Hema and Kaushik” falls into four parts. Part 1 looks at “Once in a Lifetime,” the first text of Lahiri’s trilogy, with a view to showing how the apostrophic form of the text opens up a space of mourning which might blur the boundaries between absence and presence, return and arrival, self and other, but also positions Kaushik, for Hema, as a transitionary figure whose absence might well prove crucial in letting Hema-as-narrator acquire her own generational voice. Part 2 is devoted to “Year’s End,” and investigates the ways in which Lahiri employs the Gothic to represent the second generation as being haunted by its own belatedness in relation to the first generation’s experiences. The psychoanalytic theories of Nicolas Abraham and Maria Torok, among others, will help me clarify how the dead-mother metaphor, in “Hema and Kaushik,” proves tightly interweaved with notions of transgenerational transmission, connection, and infiltration. Calling into question the possible unity of the “I” in the second text of the trilogy, Part 3 tracks the mole, so to speak, and bears witness to aspects of Lahiri’s work that are not all “in the words,” but “among the words,” to borrow Marcel Proust’s suggestive phrase, notably by revisiting aspects of “Once in a Lifetime” and “Years’ End” that are given a new significance through the interplay of the three texts of the trilogy. Relying on André Green’s concept of the “dead mother,” I will then propose an alternative reading of Lahiri’s trilogy in which Hema’s and Kaushik’s romance is only a surface-plot, enlisted to give representability to “the great unspeakable” of Hema’s life. In Part 4, Jean Laplanche’s description of the formation of the ego and the unconscious in relation to “early messages of the m/other” will allow me to look behind the curtain of transgenerational forms of melancholia, to that place where infinite longing is shown to organize itself not around any “real thing” but around a phantom entity whose idealization covers up the necessity to grapple with one’s involvement in a history of loss, which is also a history of guilt.

A study was conducted to assess the behavioural response of southern right whales (Eubalaena australis) to human-induced disturbance in Bahía San Antonio, Province of Río Negro, Argentina. Behavioural observations were made from June to October in 2008, 2009, and 2010. Aerial observa-tions carried out in 2010 show that up to one third of the whale groups were mating groups, indicat-ing that the study area is an important reproduction area for the species. The study compares 65.8 h (on a total effort of 120.3 h and 24 groups of whales) of land-based “undisturbed” whale behaviour obser-vations to 43.6 h of boat-based whale behaviour in a “disturbed” state (total effort of 326.1 h and 34 groups of whales). Analysis of the behavioural data show that whales significantly altered their behaviour by cutting social interactions short (on average 13%) when confronted with human short-range presence. At the same time, travelling whales experienced a significant increasing tendency to continue travelling (+21%) instead of starting to rest (-21%). However, social behavioural patterns returned swiftly to normal levels after the approach had ended, with a relative increase in “resting” (+18%) as opposed to “travelling” (-30%) rates.These data show that whale behaviour is altered by human approaches, pointing out the need for effective conservation measures and mitigation of behavioural impacts in relation to whale-based tourism.

The AVHRR (Advanced Very High Resolution Radiometer) sea surface temperature is very useful for researches in oceanography because of its high resolution. An AVHRR limitation is the high missing data percentage due to cloud coverage. In the South China Sea, the average missing data is usually more than 80%, especially more than 95% in the region near the Borneo Island. In this study, we use DINEOF tool to reconstruct a daily night-time AVHRR data set with horizontal resolution of 4km spanning from 1989 to 2009. Besides, a comparison between the results and in situ data is shown. The EOF analysis shows that the first three modes explain about 95% of seasonal variability. [less ▲]

L’hydrogène moléculaire a un potential énorme comme futur vecteur énergétique car sa combustion n’est pas polluante. Cependant, les processus industriels actuels de production contribuent substantiellement à l’effet de serre. Au contraire, une production d’H2 qui est neutre en CO2 peut être obtenue par la fermentation anaérobique obscure. Les bactéries du genre Clostridium peuvent fermenter les sucres en H2 et CO2 avec production d’ acide acétique et butyrique qui servent d’accepteurs principaux d’électrons. Cependant, en fonction de la souche/co-culture utilisée et des conditions de culture, des composés plus réduits peuvent être obtenus, par ex. l’éthanol, le lactate, ce qui réduit substantiellement le rendement final en H2. De plus, les différentes voies métaboliques et les circuits de régulation conduisant à la production d’H2 dans les clostridies ne sont pas bien connus. Dans cette étude, nous avons étudié deux sujets principaux. D’une part, nous avons étudié différentes co-cultures de Clostridium spp. dans des bioréacteurs produisant de l’H2. En suivant les co-cultures de C. butyricum et C. pasteurianum par FISH (Fluorescence in situ hybridisation) et qPCR (quantitative real-time PCR), nous avons montré que les deux espèces co-existent de manière stable durant la fermentation de différents sucres dans deux bioréacteurs. D’autre part, en utilisant Clostridium butyricum CWBI1009 comme modèle, nous avons étudié le métabolisme complexe de l’H2 chez les clostridies. La découverte de gènes nouveaux codant pour des hydrogènases [FeFe] dans les génomes séquencés a changé notre vue de la façon dont ces microbes produisent l’ H2. En effet, en utilisant différents outils moléculaires (2D-DIGE, RT-qPCR et RNA-seq), nous avons montré que dans différents conditions de milieu, différentes hydrogénases contribuent à la production d’H2. De plus, sous atmosphère d’N2 pendant la fermentation du glucose dans des conditions de pH non régulées, nous observons que la nitrogénase contribue à la production globale d’H2. De manière surprenante, alors que les clostridies semblent bien équipées pour produire de l’H2, elles n’ont probablement développé cette capacité que pour s’adapter rapidement aux variations de conditions, cad la diminution du pH. Donc, pour maintenir un pH intracellulaire constant, elles rejettent les protons (sans doute sous forme de H2) dans le milieu. Ainsi, elles se débarrassent de l’excès d’équivalents réducteurs produits pendant la fermentation du glucose. En résumé, nos résultats contribuent à une meilleure connaissance du métabolisme complexe de l’H2 chez les clostridies. Cependant, un défi pour le futur consiste à caractériser les enzymes responsables de ce métabolisme et, par bioengineering métabolique, de développer des systèmes microbiens optimaux pour la conversion de la biomasse en H2.
