Michele Cometa
2021
This essay is about Michele Cometa, essayist, literary and aesthetic critic and one of the founders of Italian Visual Culture ,both as a cultural approach and as an academic discipline (or, rather, un-discipline). He is responsible for the reception of W.J.T. Mitchell in Italy, having edited the first translations of his works (see, Pictorial Turn. Essays on Visual Culture, 2008, new edition 2017). He also organized the first meeting entirely devoted to the discipline in 2007, hosting the encounter between Mitchell’s Pictorial turn and Belting’s Iconic Turn and the different approaches they gave origin to in Italy.
Recensione di Cometa M. (2017), Il Trionfo della morte di Palermo. Un’allegoria della modernità, Quodlibet, Macerata
2019
Michele Cometa’s book analyzes the fifteenth-century fresco Il Trionfo della Morte (The Triumph of Death), conceived for the courtyard of the Ospedale Grande e Nuovo of Palazzo Sclafani in Palermo and currently housed in the Regional Gallery of Palazzo Abatellis, in the same city. The approach is inspired by Visual Culture studies: there are historical reconstructions and references to previous critical analyses of the pictorial work, but the fresco is interpreted in a new way, considering its narrative structure, thematic clusters as well as the allegories, the medieval topoi and the different cultural influences present in Sicily at the time.
Variability of pesticide mineralization in individual soil aggregates of millimeter size
2002
The aim of this study was to compare the 2,4-D mineralization in individual aggregates of millimeter size (3 size classes and 96 aggregates per size class). 14 CO 2 coming from the mineralization of 14 C ring-labeled 2,4-D and evolved by each aggregate incubated in microtiter plates was trapped with barium hydroxide on filters and measured using a Phosphorimager. We observed an important variability of mineralization in aggregates of each size class and in the different size classes of aggregates. The main factors responsible for these fluctuations could be a heterogeneous distribution of degrading microorganisms or of available carbon necessary for cometabolism.
Análisis espectroscópico de fragmentos cometarios y asteroidales a su entrada en la atmósfera terrestre.
2002
En la presente tesis se analiza el origen y composición de la materia interplanetaria a partir de una perspectiva nueva basada en el estudio de los fenómenos luminosos que producen estas partículas a su entrada a la atmósfera terrestre, llamados meteoros. Estas partículas, procedentes mayoritariamente de la degradación de las superficies de cometas y asteroides, cuando se hayan en órbita solar se denominan genéricamente meteoroides. Dependiendo de la geometría del encuentro con la Tierra los meteoroides alcanzan la atmósfera a velocidades comprendidas en el rango de 11 a 73 km/s. A estas velocidades a alturas de entre 120 y 70 km. la densidad atmosférica es suficiente para que las colisione…
Modelling of the cometabolic decomposition of 4-chlorophenol and phenol by the Stenotrophomonas maltophilia KB2 strain
2017
Zaprezentowano model rozkładu 4-chlorofenolu przez szczep Stenotrophomonas maltophilia KB2 w obecności fenolu jako substratu wzrostowego. Opracowanie tego modelu wymagało wykonania czterech serii badań: biodegradacji różnych dawek czystego fenolu, biodegradacji różnych dawek czystego 4-CP, biodegradacji 4-CP w obecności fenolu przy różnym stosunku stężeń obu substratów oraz biodegradacji 4-CP przez komórkiw fazie spoczynku, indukowane wstępnie fenolem. Szczegółowo omówiono sposoby wyznaczania poszczególnych parametrów równań opisujących szybkość degradacji substratów wzrostowego i niewzrostowego oraz przyrostu biomasy. W oparciu o stworzoną bazę danych obliczono m.in. stałe półnasycenia KSg…
