Captain Daylight and the big hold-up.

El Capitán Daylight es un simpático asaltante de caminos, al que le gusta más gastar bromas a la gente que robar. Pero un día, decide que quiere cambiar su imagen y para ello se disfraza como el osado atracador de diligencias, Black Jack Midnight. Sin embargo, su carácter bonachón y su torpeza no han cambiado con el nuevo ropaje.

"Jack Black's story of his life as a professional thief." --Foreword.

Hypothesizing Device Mechanisms: Opening Up the Black Box

I describe an approach to forming hypotheses about hidden mechanism configurations within devices given external observations and a vocabulary of primitive mechanisms. An implemented causal modelling system called JACK constructs explanations for why a second piece of toast comes out lighter, why the slide in a tire gauge does not slip back inside when the gauge is removed from the tire, and how in a refrigerator a single substance can serve as a heat sink for the interior and a heat source for the exterior. I report the number of hypotheses admitted for each device example, and provide empirical results which isolate the pruning power due to different constraint sources.

L’univers dans un point noir : esthétique et matérialité dans l’oeuvre de Jack Kirby

Notre recherche étudie les particularités esthétiques et matérialistes de l’oeuvre du bédéiste américain Jack Kirby (1917-1994) et la manière dont elles répondent d’agencements qui visent à déconstruire et reconstruire les formes sur la page. Contemporain de Will Eisner, Kirby est largement considéré comme l'auteur et dessinateur le plus influent de son époque, co-signant les premières aventures de certains des super-héros qui perdurent et qui sont aujourd’hui la manne de l’industrie hollywoodienne (Captain America, les Fantastic Four, Hulk, etc.). Son oeuvre protéiforme est composée de superpositions de textures, d’objets récupérés, de figures déviées et trouve dans son rapport à la matière les principaux axiomes qui la définissent. Cherchant dans son travail à cerner les fonctions des nombreux amoncellements de points noirs (baptisés kirby dots par la critique et l’industrie), nous nous écartons des modèles d’analyse sémiologiques pour constituer une approche écosophique de la bande dessinée. Dans cette dernière, nous avons recours à la schizo-analyse théorisée par Gilles Deleuze et Félix Guattari dans leur ouvrage L’Anti-OEdipe (1972) afin de cerner les conditions de la production de sens et de non-sens du point kirbyen. Pour ce faire, nous proposons de reconsidérer la BD comme une écologie séquentialisée, composée de cases sans icônes, c’est-à-dire d’un espace pris au plus près de la planche, pour soi et en soi, sans rapport de causalité fixe ou de structure prédéterminée. Nous envisageons ensuite les territorialités archaïques de la bande dessinée pour mieux définir son ontogénie, puis pour étudier les rapports machiniques et schizos qu’entretiennent entre eux les différents espaces (que nous distinguons en espaces striés et en espaces lisses) ainsi que les différents traits de la planche. Finalement, nous expliquerons en quoi le point kirbyen apparaît comme une machine abstraite, c’est-à-dire une instance capable d’auto-générer, d’auto-poïétiser, son propre mystère représentationnel.

Biogeochemical measurements of sediments collected in the Black Sea during the MSM15/1 cruise in 2010

Biogeochemical measurements in sediment cores collected with a TV-MUC in the Black Sea during MSM15/1, Northwest Crimea (HYPOX Project), at water depths between 105-207 m. Sampling was performed along gradient of oxygen bottom water concentrations between oxic (150 µmol L-1), variable hypoxic (3-60 µmol L-1 O2) and anoxic, sulfidic conditions. concentrations of organic carbon (Corg) and nitrogen (N) were measured on finely powdered, freeze-dried subsamples of sediment using a using a Fisons NA-1500 elemental analyzer. For organic carbon determination samples were pre-treated with 12.5% HCl to remove carbonates. Chlorophyll a (chl a), phaeopigments (PHAEO) and chloroplastic pigment equivalents (CPE) was measured according to Schubert et al., (2005) and total hydrolyzable amino acids (THAA) and single amino acid: ASP, GLU, SER, HIS, GLY, THR, ARG, ALA, TYR, MET, VAL, PHE, ILE, LEU, LYS following Dauwe et al., 1998.

Biogeochemical measurements in sediment cores collected with the submersible JAGO (pusch cores) and a TV-MUC in the Black Sea during MSM15/1, Northwest Crimea (HYPOX Project), at water depths between 152-156 m. A series of microbial mats were sampled on the hypoxic region of the Crimean Shelf. Concentrations of organic carbon (Corg) and nitrogen (N) were measured on finely powdered, freeze-dried subsamples of sediment using a using a Fisons NA-1500 elemental analyzer. For organic carbon determination samples were pre-treated with 12.5% HCl to remove carbonates.
