  1. “A Lock of Thy Bright Hair”: The Enlightenment’s Milton and Our Auratic Material

    Directory of Open Access Journals (Sweden)

    2015-11-01

    Full Text Available This article looks at how English critics, biographers, and poets once sported with the image, idea, and biomaterial of John Milton’s hair. Their play is contextualized within the materialist and instrumental values that were instituted in eighteenth-century literary criticism and biography and that remain central to the humanities today. It was the philologists, antiquarians, bibliophiles, biographers, and anecdotalists of the long eighteenth century who linked the value of cultural objects to their work in the cultural world. The objects sheltered from that world—aesthetic ones in the modern sense—were meanwhile endowed with qualities purloined from an otherwise debunked supernatural register. These contradictory values, all object-centered, cultivated skepticism in observers and thus scripted still-privileged affective postures of mourning and melancholia with respect to objects of inquiry. Dynamic entanglement with Milton’s hair in eighteenth-century critical writing tells a different story. It teaches us to approach that writing as writing and to value “Milton’s hair” as auratic in the communicative sense later displaced by diffident, object-centered models of the aura. Can we define and engage our “material” along the lines of eighteenth-century “entanglement” with Milton’s hair?

    Nick Peim has recently revisited the work of Walter Benjamin; specifically his famous essay on art and mechanical reproduction. In this reply, I too draw upon the inspiration of Benjamin to extend the argument to the question of experience and what might count as knowledge, both in a philosophical sense and also in terms of the curriculum.

  4. A joint data record of tropospheric ozone from Aura-TES and MetOp-IASI

    Full Text Available The Tropospheric Emission Spectrometer (TES on Aura and Infrared Atmospheric Sounding Interferometer (IASI on MetOp-A together provide a time series of 10 years of free-tropospheric ozone with an overlap of 3 years. We characterise the differences between TES and IASI ozone measurements and find that IASI's coarser vertical sensitivity leads to a small (< 5 ppb low bias relative to TES for the free troposphere. The TES-IASI differences are not dependent on season or any other factor and hence the measurements from the two instruments can be merged, after correcting for the offset, in order to study decadal-scale changes in tropospheric ozone. We calculate time series of regional monthly mean ozone in the free troposphere over eastern Asia, the western United States (US, and Europe, carefully accounting for differences in spatial sampling between the instruments. We show that free-tropospheric ozone over Europe and the western US has remained relatively constant over the past decade but that, contrary to expectations, ozone over Asia in recent years does not continue the rapid rate of increase observed from 2004 to 2010.

    Full Text Available My essay presents the emerging of fake as a concept that does not mean false, but a post-dualistic mix of false/truth. The relation between digital culture and ubiquitous subjectivity is fundamental during its process; in the same way, the relation between aura and reproducibility cannot be determined dialectically as Benjamin did. Digital auratic reproducibility is the contemporary context and communicational metropolis is characterized by spontaneous and public performance: so, my conclusion is an analysis of some “living” doll and their uncanny presence.

    Highlights: • Tetracyclines directly reduce aurate into gold nanoparticles. • Gold nanoparticles showed characteristic plamson absorbance at 526 nm. • Quantitative detection of tetracyclines with the colorimetric assay. • Tetracyclines spiked urine samples can be detected with the assay. - Abstract: A colorimetric assay utilizing the formation of gold nanoparticles was developed to detect tetracycline antibiotics in fluidic samples. Tetracycline antibiotics showed the capability of directly reducing aurate salts into atomic gold which form gold nanoparticles spontaneously under proper conditions. The resulted gold nanoparticles showed characteristic plasmon absorbance at 526 nm, which can be visualized by naked eyes or with a spectrophotometer. UV–vis absorbance of the resulted gold nanoparticles is correlated directly with the concentrations of tetracycline antibiotics in the solution, allowing for quantitative colorimetric detection of tetracycline antibiotics. Reaction conditions, such as pH, temperature, reaction time, and ionic strength were optimized. Sensitivity of the colorimetric assay can be enhanced by the addition of gold nanoparticle seeds, a LOD as low as 20 ng mL −1 can be achieved with the help of seed particles. The colorimetric assay showed minimum interference from ethanol, methanol, urea, glucose, and other antibiotics such as sulfonamides, amino glycosides etc. Validity of the method was also evaluated on urine samples spiked with tetracycline antibiotics. The method provides a broad spectrum detection method for rapid and sensitive detection of reductive substances such as tetracycline antibiotics in liquid and biological samples

    Full Text Available The development of era demands muslimahs to take roles without leaving their identities. When they became career women, they were asked to work outside their houses. How if the women want to keep their faith and obey the Islamic rules by keeping their aurat with jilbab (veil? Will jilbab disturb their activities when working? How if their working environments do not accept them? The paper discusses the relationship between the activities of women with hijab and their adaptation by analyzing Fatins Hijab Diary. With Scheiders analysis, it can be concluded that Fatin Shidqia Lubis, as an entertainer and public figure has conducted the adaptation process toward her working environment in order to be exist in it without leaving her identity as a muslimah who holds the hijabs principals. The process that has been successfully passed by Fatin shows that jilbab is not an obstruction for women who want to work and be famous.

  11. Honey From Maggots: Aura, Sacrifice, and the Human Universe in Charles Olson's "The Kingfishers"

    Science.gov (United States)

    Roethle, Christopher James

    In this thesis, I contend that some form of aura can be recovered from the ravages of technological reproduction described in Walter Benjamin's "The Work of Art in the Age of its Technological Reproducibility (Third Version)." Recovering this aura, however, may require adopting an aesthetic of immediacy through destruction and even wanton disposability (what Georges Bataille in his general economic theory calls "nonproductive expenditure") to ensure that, though routinely diluted and discarded, the split-second authenticity of a work remains, its radical ephemerality and formal irreproducibility opposing the enslaving, commodifying powers of the copy. The poetry and poetic theory of American poet Charles Olson, especially in his long poem "The Kingfishers" and his essays "Projective Verse" and "Human Universe," serves as an example of how an author might inscribe auratic energy along nonproductive, general economic lines.

  12. Engineering of poly(ethylene glycol) chain-tethered surfaces to obtain high-performance bionanoparticles

    Nagasaki, Yukio

    2010-01-01

    A poly(ethylene glycol)-b-poly[2-(N,N-dimethylamino)ethyl methacrylate] block copolymer possessing a reactive acetal group at the end of the poly(ethylene glycol) (PEG) chain, that is, acetal-PEG-b-PAMA, was synthesized by a proprietary polymerization technique. Gold nanoparticles (GNPs) were prepared using the thus-synthesized acetal-PEG-b-PAMA block copolymer. The PEG-b-PAMA not only acted as a reducing agent of aurate ions but also attached to the nanoparticle surface. The GNPs obtained had controlled sizes and narrow size distributions. They also showed high dispersion stability owing to the presence of PEG tethering chains on the surface. The same strategy should also be applicable to the fabrication of semiconductor quantum dots and inorganic porous nanoparticles. The preparation of nanoparticles in situ, i.e. in the presence of acetal-PEG-b-PAMA, gave the most densely packed polymer layer on the nanoparticle surface; this was not observed when coating preformed nanoparticles. PEG/polyamine block copolymer was more functional on the metal surface than PEG/polyamine graft copolymer, as confirmed by angle-dependent x-ray photoelectron spectroscopy. We successfully solubilized the C 60 fullerene into aqueous media using acetal-PEG-b-PAMA. A C 60 /acetal-PEG-b-PAMA complex with a size below 5 nm was obtained by dialysis. The preparation and characterization of these materials are described in this review. (topical review)

  14. Monumentality and public space in Lourenço Marques in the 1930 and 1940

    2012-01-01

    Full Text Available Lourenço Marques, actual Maputo (Mozambique, is subjected to a series of aesthetic interventions in its public space during the 1930s e 1940s. These seek to “monumentalize” and “portugalize” the city, responding to its recently acquired status as capital of the Colony. Two monuments appear as especially important and exemplary: the Padrão de Guerra, a lately built First War memorial (1935, and the monument to the hero of the “pacification campaigns” of the 1890s, Mouzinho de Albuquerque (1940. Around these monuments, a large number of commemorative and celebrative practices are developed. Such practices posit the monument as a “national allegory” and reproduce, in the context of a modern city, auratic and cult values. As such, they add an important dimension to the monument’s role in the authoritarian reformulation of the city’s public space as an “imperial” space, as well as in the putative hegemonization of the representations of the community imagined as a “Nation”. They allow, therefore, to approach the political-ideological use and utility of the monument within the organization of public space.

  15. Petyarre and Moffat: 'Looking from the Sky'

    Full Text Available Moffatt’s Up in the Sky series draws attention to the relation between sky and earth, through the content and camera angles of the images. Similarly, Kathleen Petyarre’s Central Desert acrylic dot painting evokes this relation representing country and Dreaming from a celestial perspective—as she says ‘looking from the sky’. Yet here any association between these artists seems to end with the urban artist refusing to engage Aboriginal tradition and the desert artist focused on Dreaming, country and heritage. However, a further connection between these disparate works may also be discerned as each, in differing ways, transforms our conventional perceptions of space and time. Reading these images in relation to Walter Benjamin’s concepts of the auratic and of messianic time, I suggest that each restructures dimension and duration putting in question the (postmodern calibrations of our space/time experience. This paper stages an engagement between these artists’ works and Benjamin’s concepts exploring the variations and modifications of the spatial and the temporal that hybrid cross-cultural exchanges require and facilitate.

  17. Pagbalangkas sa Arkitekturang Filipino: Alternatibong Kritikal na Tema sa Historyograpiyang Arkitektural

    Directory of Open Access Journals (Sweden)

    Edson Roy G. Cabalfin

    2000-12-01

    Full Text Available There is a need to restudy and reframe the methodologies we use to present the history of Filipino Architecture. The paper is rooted in the idea that the current approach to historiography of Filipino architecture renders architecture itself irrelevant and detached from the students of architectural history. Postcoloniality is seen here as a conscious break from traditional notions of historiography and a means of empowerment for the marginalized. In Filipino Architecture, this implies a non-elitist and anti-auratic approach in looking at architecture. Furthermore, there is also a shift in looking at architecture not just as mere products, but more importantly as a process. In lieu of the popular diachronic-historic approach to architectural history writing, a synchronic-thematic system is proposed. To understand further the relevance of architecture to the lives of the Filipino, five critical themes were proposed as alternative ways of looking at architecture. The themes are: Architecture as Signifier of Places and Settings; Architecture as a Mode of Signifying Meaning; Architecture as Process of Creativity; Architecture as Adaptation and Adjustment to the Environment; and Architecture as Sites of Power Relations. With these critical themes, Filipino architecture is seen as a means of empowering the Filipino instead of being the source of oppression.

  18. Algunas reflexiones desde la acuarela de Mario Conde

    2012-11-01

    Full Text Available This brief reflection on the work of Mario Conde starts paying attention to the special relationship the artist has with the watercolor technique, deploying from that relationship a copy-based ethics. From that materiality Conde builds his response to the postmodern moment in which art in general, and particularly Bolivian art, is been developed given its current social conditions. The ethics of the copy is explored especially in two of his works: "Exterminator Angel" where  copying addresses colonial issues that return to question and challenge the very notion of homeland, and "Drunk with power (Géricault in Los Andes" where the copy,  adapted to Andean latitudes, exudes a desire to restore the sacred and  auratic character of artwork as well as of the Andean imagery.Esta breve reflexión sobre la obra de Mario Conde se inicia poniendo atención en la relación particular que tiene el pintor con la técnica de la acuarela, desplegando desde esa relación una ética basada en la copia. Desde esa materialidad Conde concretiza su respuesta al momento posmoderno en que se desarrolla el arte en general, y el boliviano en particular dadas sus condiciones sociales actuales. La ética de la copia es explorada especialmente en dos de sus obras: “Ángel exterminador” donde la copia aborda temáticas coloniales que retornan para poner en cuestión y entredicho la noción de patria, y “Ebrios de poder (Géricault en Los Andes” donde la copia adaptada a latitudes andinas destila un deseo de restablecer el carácter sagrado y aurático de la obra de arte como del imaginario andino.

    Full Text Available Microbes are suitable candidates to recover and decontaminate different environments from soluble metal ions, either via reduction or precipitation to generate insoluble, non-toxic derivatives. In general, microorganisms reduce toxic metal ions generating nanostructures (NS, which display great applicability in biotechnological processes. Since the molecular bases of bacterial reduction are still unknown, the search for new -environmentally safe and less expensive- methods to synthesize NS have made biological systems attractive candidates. Here, 47 microorganisms isolated from a number of environmental samples were analyzed for their tolerance or sensitivity to 19 metal(loids. Ten of them were highly tolerant to some of them and were assessed for their ability to reduce these toxicants in vitro. All isolates were analyzed by 16S rRNA gene sequencing, fatty acids composition, biochemical tests and electron microscopy. Results showed that they belong to the Enterobacter, Staphylococcus, Acinetobacter, and Exiguobacterium genera. Most strains displayed metal(loid-reducing activity using either NADH or NADPH as cofactor. While Acinetobacter schindleri showed the highest tellurite (TeO32- and tetrachloro aurate (AuCl4- reducing activity, Staphylococcus sciuri and Exiguobacterium acetylicum exhibited selenite (SeO32- and silver (Ag+ reducing activity, respectively. Based on these results, we used these bacteria to synthetize, in vivo and in vitro Te, Se, Au, and Ag-containing nanostructures. On the other hand, we also used purified E. cloacae glutathione reductase to synthesize in vitro Te-, Ag-, and Se-containing NS, whose morphology, size, composition, and chemical composition were evaluated. Finally, we assessed the putative anti-bacterial activity exhibited by the in vitro synthesized NS: Te-containing NS were more effective than Au-NS in inhibiting Escherichia coli and Listeria monocytogenes growth. Aerobically synthesized TeNS using MF09 crude

    2010-12-01

    Full Text Available Sophie Calle's texts are elaborate devices that facilitate the production of figures, of complex symbolic entities. In fact, her work enables us to better understand how figures emerge and unfold in the imaginary. Thus, we find in her Disparitions (Disappearances, a startling figure, which we can name the "Vanished Child". I will present this figure and explain how it stems from the description of a painting by Rembrandt, stolen at the Gardner Museum in Boston. I will start by identifying some of the essential processes implied in the identification of a figure, and, to do so, I will give two short examples, drawn from Witold Gombrowicz and Don DeLillo. Then, after having described in details the figure of the Vanished Child, I will argue, following the French art historian Georges Didi-Huberman in his reading of Walter Benjamin, that figures are auratic objects. Dans ses textes, Sophie Calle emploie des techniques détaillées qui facilitent la production de figures, d'entités symboliques complexes. Son œuvre nous permet effectivement de mieux comprendre comment les figures émergent et se déploient dans l'imaginaire. Ainsi, nous trouvons dans ses Disparitions (Disappearances une figure surprenante que nous pouvons désigner comme « l'enfant disparu ». Je présenterai cette figure en expliquant comment elle découle de la description d'un tableau de Rembrandt volé au musée Gardner à Boston. J'identifierai d'abord quelques-uns des procédés essentiels à l'identification d'une figure, et pour ce faire je donnerai deux exemples, tirés des œuvres de Witold Gombrowicz et Don DeLillo. Puis je décrirai de façon détaillée la figure de l'enfant disparu, avant de démontrer le caractère auratique des figures à partir de la lecture de Walter Benjamin qu'exécute l'historien de l'art français Georges Didi-Huberman.
