La liofilizzazione quale intervento di recupero di volumi alluvionati ed attaccati da Microfunghi
No full textNegli ultimi venti anni diversi trattamenti di liofilizzazione di massa sono stati utilizzati
e documentati nel caso di materiali librari danneggiati da alluvioni o andati
sommersi. Il trattamento permette di evitare l’adesione dei fogli cartacei gli uni agli
altri e previene la migrazione di inchiostri o altri composti solubili. Lo scopo del
presente lavoro riguarda gli effetti della liofilizzazione sui funghi biodeteriogeni
che attaccano la carta bagnata. Su campioni di carta infettati con tre specie di funghi
e sottoposti a tre differenti trattamenti (liofilizzazzione, sterilizzazione con il
calore, controllo vitale non trattato) sono stati effettuati due test di vitalità: un test
colturale e l’analisi del contenuto in ATP. La liofilizzazione ha comportato rispetto
al controllo una diminuzione sensibile del contenuto in ATP di tutti e tre i ceppi
fungini ed in modo più marcato nel C.cladosporioides e nel T.viridae rispetto al C.globosum.
Una significativa differenza è stata registrata inoltre fra dato colturale e contenuto
in ATP. Ciò si deve al diverso effetto nocivo che ha la liofilizzazione nei confronti
del micelio fungino rispetto ai conidi ed alle ascospore. Sembra cioè che la
liofilizzazione sia capace di uccidere o di deprimere il micelio e solo in parte i
conidi e le spore
Joan Thorne, Analytic Ecstasy
No full textThe article focuses on American artist Joan Thorne. The author examines several of her abstract panitings, including Squazemo, Aahee, and Ananda, explores how her work relates to minimalism, non-composition, and postmodernism, and discusses her role in the women\u27s art movement of the 1970s in New York City
Lorna Simpson, by Joan Simon et al., Prestel: Munich, 2013 (Book Review)
No full text[First paragraph] The images and essays in this catalogue, which documents Lorna Simpson\u27s (b. 1960) first museum exhibition in Europe,1 trace an increasing emphasis on the enigmatically personal at the expense of the linguistic, although her work remains concerned with the discursive behavior of images as they reveal assumptions about race and gender. Simpson, as the author and contributors show, activates looking by short-circuiting the possessive aspects of the gaze
Method of thermally glazing an article, U.S. Patent 6,127,005
No full textCoating and filler materials for localized thermal processing of glazed ceramics and other brittle and low thermal conductivity materials. The coating materials include oxide compositions that exhibit coefficients of thermal expansion which are less than about 8×10-6 /° C. and glass transition temperatures which are less than about 400° C. The filler materials include particulate oxide materials which do not substantially react during localized thermal processing of glazed ceramics and other brittle and low thermal conductivity materials. The coating and filler materials are useable together as a composite material for repairing cavities having depths greater than about 2 mm
De la aldea global al circuito integrado
No full textL'autora fa seva I'analisi semidtica de F. Rossi-Landi entorn de la relació entre economia i Ilenguatge, i des d'aquí aborda els efectes de la mundialització de I'economia i la comunicació. En aquest punt oposa certs aspectes de la teoria de McLuhan a un nou mapa político-cognitium que Donna Haraway ha presentat amb el nom de acircuit integrat. Examina Ilavors les transformacions que la nova situació genera en el subjecte i la societat. I acaba suggerint una resposta que parteix del rebuig de categories ontologiques com ara la identitat, negant així mateix -a partir de Benjamin- que en el camp artístic les velles categories puguin tenir validesa com a eina de comprensió. El cyborg és la metafora o amite ironico-polític en que s'encarna aquesta resposta.The author bases his semiotic analysis of F. Rossi-Landi on the relationship between the economy and language, and from here examines the effects of the globalization of the economy and communication. Here, he contrasts certain aspects of McLuhan's theory with a new "politico-cognitive map" to which Donna Haraway has given the name "integrated circuit". He, then, examines the transformations that the new situation generates in the subject and society. He concludes by suggesting a reply based on the rejection of ontological categories such as identity, thus denying -as did Benjamin before him- that in theartislic field earlier categories can still be valid as interpretative tools. The cyborg is the metaphor or "ironic-political-myth" in which the response is embodied
Tactility and Opticality in Contemporary Abstract Painting
No full textThe thesis analyses the construction of surface in contemporary abstract painting and its broader implications, mainly in regard to Clement Greenberg´s understanding of modernist painting. It considers how this issue was contended between art critics such as Greenberg and Michael Fried and artists that challenged the formalist account of painting´s medium specificity through a wide range of procedures and techniques. I review Thierry de Duve´s analysis of Robert Ryman´s work in regard to Greenberg´s understanding of modernist painting and discuss the ways in which the contest between painting and photography (since photography made painting reproducible) is central.
The analysis of Ryman´s work leads to a consideration of Duchamp´s readymade and its significance to painting. Painting´s resistance to being annexed by photography follows de Duve´s contention in regard to painting-photography competitiveness where he argues that opposition to photographic reproducibility has been critical for painting since the invention of photography. At this point the historical significance of Duchamp´s readymade is regarded as a repetition of the invention of photography within the domain of painting.
The assertion is then that the key to contemporary abstract painting – what supports its attraction – is the manner in which the construction of surface is made through the reformulation of pictorial practices that were developed from the 1960s – such as Informel – and continue to be elaborated in a contemporary context in the works of artists like Katharina Grosse or Sergej Jensen. By considering Informel as a manifestation of a painting-photography contest I argue for its value in contemporary abstract painting as a means to further develop abstract painting´s potentiality, as Katharina Grosse and Sergej Jensen do through their engagement with architectural space
Touch: an enquiry
No full textThis thesis forms part of a practice-based enquiry into ‘touch’ from a painter’s perspective. I am investigating touch as a three-way interplay: 1. the act of touch at work in the studio; 2. the sense of touch experienced with and in my body while engaging with my own work and with the paintings of Robert Ryman; and 3. the presence of touch, materially and metaphorically, in the work as a result of my reflective practice in response to an analysis of 1 and 2. I examine the making of two sections of studio work, Touch Screen and Where’s the ’Ouch?; analyse the findings of three days spent with the Ryman installation in the Hallen für Neue Kunst, Schaffhausen, Switzerland; and reflect on the making of a third section of my studio work, Blanks in response to the Hallen experience

No full textPresented at Proceedings of the 24th annual Central Plains irrigation conference held on February 21-22 in Colby, Kansas.Remotely sensed plant canopy temperature has long been recognized as having potential as a tool for irrigation management. However, a number of barriers have prevented its routine use in practice, such as the spatial and temporal resolution of remote sensing platforms, limitations in computing capacity and algorithm accuracy, and the cost and ruggedness of sensors and related components that can transmit and receive data wirelessly. Recent advances in all of these areas have made remote sensing more feasible in providing real-time feedback of field conditions. This can potentially reduce management time, maintain crop yield and crop water productivity, and detect unusual conditions such as equipment malfunctions or biotic stress sooner. Center pivots equipped with wireless infrared thermometers (IRTs) have been found to be suitable as a remote sensing platform. Canopy temperature-based algorithms have successfully automated drip and center pivot irrigation schedules where crop yield, water use efficiency, seasonal water use, and irrigation amounts applied were comparable to irrigations scheduled manually with a field-calibrated neutron probe. Even without automation, these algorithms can provide timely and valuable information on plant and soil water status, which can improve the management of irrigated crops
