The bacterial and microeukaryotic biodiversity was studied using pyrosequencing analysis on a 454 GS 29 FLX+ platform of partial SSU rRNA genes in terrestrial and aquatic habitats of the Sør Rondane Mountains, 30 including soils, on mosses, endolithic communities, cryoconite holes, and supraglacial and subglacial 31 meltwater lenses. This inventory was complemented with Denaturing Gradient Gel Electrophoresis targeting 32 Chlorophyta and Cyanobacteria. OTUs belonging to the Rotifera, Chlorophyta, Tardigrada, Ciliophora, 33 Cercozoa, Fungi, Bryophyta, Bacillariophyta, Collembola and Nematoda were present with a relative 34 abundance of at least 0.1% in the eukaryotic communities. Cyanobacteria, Proteobacteria, Bacteroidetes, 35 Acidobacteria, FBP, and Actinobacteria were the most abundant bacterial phyla. Multivariate analyses of the 36 pyrosequencing data revealed a general lack of differentiation of both eukaryotes and prokaryotes according 37 to habitat type. However, the bacterial community structure in the aquatic habitats was dominated by the 38 filamentous cyanobacteria Leptolyngbya and appeared to be significantly different compared with those in 39 dry soils, on mosses, and in endolithic habitats. A striking feature in all datasets was the detection of a 40 relatively large amount of sequences new to science, which underscores the need for additional biodiversity 41 assessments in Antarctic inland locations.

Partant de quelques textes dans lesquels S. Kracauer traite du rapport entre montage et réel, cet article tente de préciser et de problématiser l’ambivalence de Kracauer à l’égard de l’outil « montage », notamment dans le champ cinématographique, en ouvrant la réflexion par cette double question : comment définir un « mauvais usage » du montage et, à l’opposé, comment peuvent se mettre en place les conditions d’un « bon usage » du montage selon Kracauer ? Pour y répondre, les auteurs identifient d'abord, dans l’œuvre de Kracauer, les éléments explicites et implicites (montage textuel) qui permettent de saisir au plus près ce que serait, selon le philosophe et sociologue, le principe de réalité. Ensuite, une œuvre photographique, contemporaine des quelques textes évoqués, Menschen des 20. Jahrhunderts d’August Sander, permet de mieux circonscrire les possibles concrétisations de cette pensée en la mettant à l’épreuve d’une réalisation en images et en montage. [less ▲]

J'examine ici l’approche cartésiano-brentanienne de la conscience. Cette approche comporte une thèse psychologique ("tout ce qui est mental est conscient") et une double thèse épistémologique ("toute conscience interne est évidente"/'aucune perception externe n'est évidente"). On a souvent considéré que ces thèses se heurtaient à d’imposantes difficultés et rendaient l’approche cartésiano-brentanienne de la conscience particulièrement problématique. Contre ces critiques, certains commentateurs ont récemment suggéré qu’on pouvait toutefois donner un sens acceptable à la thèse psychologique. Je voudrais suggérer, pour ma part, qu’on peut aussi donner un sens acceptable à la double thèse épistémologique. Dans la section 2, je reconstruit la position cartésiano-brentanienne en termes d'asymétrie épistémique entre perception interne et perception externe. Dans les sections 3 et 4, je discute les objections soulevées par Husserl et par Ryle, et je suggère que la théorie brentaniexnne permet de réfuter ces objections. [less ▲]

Le thème de la conscience a connu un regain d’intérêt spectaculaire, ces dernières années, chez les philosophes et les scientifiques. Des théories nouvelles ont vu le jour dans l’espoir de rendre compte de « l’effet que cela fait », par exemple, de tomber amoureux, de se faire mal ou de… mordre dans un citron. Contrairement à une conception populaire, de nombreux chercheurs ont suggéré que ressentir quelque chose équivalait en réalité à se représenter quelque chose. L’ouvrage "Conscience et représentation. Introduction aux théories représentationnelles de l’esprit" (Paris, Vrin, 2016) dresse un état des lieux des controverses liées à cette question. [less ▲]

The classical Brown-Peterson task is generally supposed to assess working memory capacities. To date, however, the construct validity of the task remains mostly unexamined. In this context, the aim of the present study was to demonstrate the convergent and the divergent validity as well as the clinical and the developmental sensitivity of a computerized version of the Brown-Peterson test. A group of 726 French-speaking participants aged from 18 to 86 years and 47 patients who had sustained a traumatic brain injury (TBI) were administered the Brown-Peterson task and various other cognitive tasks assessing executive functioning, verbal and visual memory, or processing speed. The correlation analyses revealed the good convergent of the task, which was shown to be able to distinguish between participants with TBI and control participants. We found an effect of age and education level on the different scores recorded for the Brown-Peterson test. Normative data taking into account the influence of the latter variables were thus provided. On the whole, these findings seem to confirm the validity of the Brown-Peterson task as a tool to assess working memory abilities. [less ▲]

Bone charcoal (BC) is being developed as a treatment for decontaminating polluted water. In this study, bone charcoal was obtained by pyrolysis of cow bone. Further, for the wastewater depollution with these new materials, their performance in the elimination of copper from aqueous solutions has to be determined. The minimum time to reach the removal equilibrium by adsorption was 10 min with a maximum of copper removal equal to 9,615 mg/g. the kinetics models were applied to fit the our experimental data. Actually, they have show excellent correlations with the pseudo-second-order model wich has presented a linear correlation coefficient equal to 0.941. It was verified that the HCl desorption system has the highest efficiency. [less ▲]

Bien que placée dès sa préface sous le signe de la recherche du plaisir, l’Histoire de ma vie évoque très souvent le dégoût et lui assigne un rôle important dans l’intrigue, dans la caractérisation du protagoniste, dans ses réflexions sur l’amour ou dans la création d’effets comiques. Surtout perçu dans sa dimension physique et attribué à Casanova lui-même, le dégoût tend à être provoqué par des objets sexués, donc souvent par des femmes – les boutonneuses, les prostituées, les vieilles... Mais il n’est pas question de choquer le lecteur par des évocations dégoûtantes. Des normes sont maintenues : esthétiques (il s’agit de « bien peindre »), individuelles (Casanova a avoué ses gros goûts et son attrait pour le haut goût) et morales (mais il s’adresse à des initiés). L’absence et la disparition du dégoût sont également souvent notées, qu’elles renvoient à une stratégie d’évitement, à une incompatibilité du dégoût avec l’amour ou à une insensibilité protectrice. Il faut s’interroger aussi sur la suspension du dégoût chez le lecteur, pourtant confronté à des éléments racontés qu’il pourrait juger répugnants – n’est-ce pas là le signe que Casanova parvient à nous imposer sa vision ?

The Childhood Executive Functioning Inventory (CHEXI) is a new rating instrument for executive functioning developed by Thorell and Nyberg (2008). Through exploratory factor analyses, this inventory has been shown to tap into working memory and inhibition-related behaviors in young children. In this study, we present the psychometric characteristics of the French adaptation of the CHEXI in 8- to 11-year-old children. In addition, we explore the cross-cultural validity of the CHEXI in discriminating between children with ADHD and normally developing children in two culturally different samples (Belgian and Swedish). Confirmatory factor analyses replicated the two-factor solution, referred to as inhibition and working memory, that was identified in the original study with Swedish children. Supplementary analyses indicated that both subscales have good psychometric properties. From a clinical point of view, the CHEXI was found to discriminate, with high sensitivity and specificity, between children with ADHD and normally developing controls in both cultural samples. Cross-cultural clinical implications are discussed. [less ▲]

Microalgae are currently emerging to be very promising organisms for the production of biofuels and high-added value compounds. Understanding the influence of environmental alterations on their metabolism is a crucial issue. Light, carbon and nitrogen availability have been reported to induce important metabolic adaptations. So far, the influence of these variables has essentially been studied while varying only one or two environmental factors at the same time. The goal of the present work was to model the cellular proteomic adaptations of the green microalga Chlamydomonas reinhardtii upon the simultaneous changes of light intensity, carbon concentrations (CO2 and acetate) and inorganic nitrogen concentrations (nitrate and ammonium) in the culture medium. Statistical design of experiments (DOE) enabled to define 32 culture conditions to be tested experimentally. Relative protein abundance was quantified by two dimensional differential in-gel electrophoresis (2D-DIGE). Additional assays for respiration, photosynthesis, and lipid and pigment concentrations were also carried out. A hierarchical clustering survey enabled to partition biological variables (proteins + assays) into eight co-regulated clusters. In most cases, the biological variables partitioned in the same cluster had already been reported to participate to common biological functions (acetate assimilation, bioenergetic processes, light harvesting, Calvin cycle and protein metabolism). The environmental regulation within each cluster was further characterized by a series of multivariate methods including principal component analysis and multiple linear regressions. This metadata analysis enabled to highlight the existence of a clear regulatory pattern for every cluster and to mathematically simulate the effects of light, carbon and nitrogen. The influence of these environmental variables on cellular metabolism is described in details and thoroughly discussed. This work provides an overview of the metabolic adaptations contributing to maintain cellular homeostasis upon extensive environmental changes. Some of the results presented here could be used as starting points for more specific fundamental or applied investigations. [less ▲]

In this paper, an easy aqueous sol-gel synthesis developed previously by Mahy et al. [J. Sol-Gel Sci. Technol. (2016)] is adapted to produce highly active TiO2 catalysts doped with Fe3+, Ag+, Cu2+, Zn2+, Cr3+, Al3+, Mn2+, and Co2+ ions and Pt metallic nanoparticles. Samples are characterized by inductively coupled plasma–atomic emission spectroscopy (ICP-AES), X-ray diffraction (XRD), Mössbauer spectroscopy, transmission electron microscopy (TEM), nitrogen adsorption–desorption measurements and diffuse reflectance spectroscopy measurements. Results show that the samples are composed of anatase-brookite TiO2 nanoparticles with a spherical shape and mean diameter of around 5-8 nm and a surface area of between about 150 - 250 m2 g-1. In each doped sample, the dopant is present in the form added during the synthesis, given that the sample has not undergone any particular treatment. Photoactivity tests show improvement in catalyst activity for Fe3+, Ag+, Cu2+, Zn2+, and Al3+ ion and Pt metallic nanoparticle dopants, while a decrease of activity is obtained for Cr3+, Mn2+ and Co2+ ion dopants. For some dopants, the activity of TiO2 doped with metallic ions and synthesized from the aqueous sol-gel process is equal or superior to the activity of the commercial photocatalyst Degussa P25. Some mechanisms are proposed to explain these modifications of activity with doping. Furthermore, cost comparison at laboratory scale showed that Zn and Cu nitrate salt dopings are clearly less expensive for a halogen light (UV/visible) or low energy light enhanced catalyst and may be considered for industrial applications. Using this method, a large scale Zn-doped TiO2 photocatalyst is synthesized with properties homologous to the lab-scale product. Results show that the aqueous sol-gel synthesis developed previously can be easily adapted for doping in order to produce an up-scalable synthesis. [less ▲]

This paper deals with adnominal possession in Ancient Egyptian, focusing on constructions involving a pronominal possessor. In early Egyptian, a single construction is attested: substantive (possessee) + bound person marker (possessor). From the 6th Dynasty onwards, a new construction, which is built from a demonstrative determiner, appears: pAy + bound person marker (possessor) + substantive (possessee). In order to describe the gradual encroachment of the innovative possessive determiner pAy-f on the older construction with the possessive bound person marker, this study proposes a discourse-oriented analysis, using the notion of ‘subjective deixis.’ [less ▲]
