Sponge-associated bacteria of Lakshadweep coral reefs, India: resource for extracellular hydrolytic enzymes  [PDF]
Annie Feby, Shanta Nair
Advances in Bioscience and Biotechnology (ABB) , 2010, DOI: 10.4236/abb.2010.14043
Abstract: Sponges (Phylum: Porifera) is one of the major groups in the Lakshadweep coral reefs. These sponges harbor diverse bacteria with metabolic potentiality. From biodiversity to biotechnological prospecting, scientific investigations related to sponge associated microorganisms have expanded, but remain rather limited to few geographic locations. In this study, culturable bacteria associated with two demosponges viz Dysidea granulosa, Sigmadocia fibulata and the ambient water were screened for commercially important enzymes such as amylase, protease, gelatinase, lipase, deoxyribonucleic, phosphatase and urease. Amylase and phosphatase were the predominant enzymes produced by >80% of sponge-associated bacteria compared to the ambient water. Nearly 50% of the sponge-associated bacteria expressed multiple enzymatic activities (> 4) with variation in the percentage of expression of individual enzymes. More than 65% of the culturable heterotrophic bacteria associated with sponges were Gammaproteobacteria. The order Vibrionales was the main source for multiple enzyme production. Sponge associated bacteria formed more closely related clusters than the water isolates based upon their activity pattern. High recovery of sponge-associated bacteria with multiple enzymatic activities suggest that these versatile bacteria are yet unexploited potential for bioprospecting.
Preferentially orientated E-beam TiN thin films using focused jet of nitrogen gas
R. Ramaseshan,Feby Jose,S. Rajagopalan,S. Dash
Physics , 2014,
Abstract: A modified electron beam evaporator has been used judiciously to synthesize TiN thin films with (111) preferred orientation. This new design involved in creating local plasma by accelerating the secondary electrons emitted from the evaporating ingot by a positively biased semi-cylindrical anode plate kept in the vicinity and a jet of N2 gas has been focused towards the substrate as a reactive gas. We have observed a preferred orientation (111) with 25 degree angle to the surface normal and this was confirmed by pole figure analysis. The phenomenon of preferred orientation (111) has been explained based on the rate of evaporation. The residual stress by the classical sin2psi technique did not yield any tangible result due to the preferred orientation. The hardness and modulus measured by nanoindentation technique was around 19.5 GPa and 214 GPa. The continuous multicycle indentation test on these films exhibited a stress relaxation.
Review: Gram Negative Bacteria in Brewing  [PDF]
Paradh Ashtavinayak, Hill Annie Elizabeth
Advances in Microbiology (AiM) , 2016, DOI: 10.4236/aim.2016.63020
Abstract: Gram negative aerobic bacteria such as Acetic Acid Bacteria, which include Acetobacter and Gluconobacter, have historically caused significant problems to brewers. Although incidences of spoilage have recently reduced as a result of improvements in beer packaging, these bacteria are still a concern in dispense systems in pub breweries, public houses and cask conditioned beers. Gram negative facultative bacteria of the genus Zymomonas can spoil primed cask conditioned beer and cider. There is a wide range of Enterobacteraeceace which are found within brewery environments and they serve as indicator microorganisms for hygiene and sanitation. Gram negative strictly anaerobic bacteria such as Pectinatus and Megasphaera have recently emerged as a significant threat due to the improvement in reduction of oxygen levels in beer and an increase in production of unpasteurised beer. Pectinatus and Megasphaera are sensitive to routine cleaning agents used in breweries, but they can survive and proliferate in biofilms eventually causing spoilage of beer. This review focuses on Gram negative aerobic, facultative anaerobic and strictly anaerobic brewery related spoilage bacteria.
Benjamin & Schmitt: uma arqueologia da exce??o
Dymetman, Annie;
Lua Nova: Revista de Cultura e Política , 2001, DOI: 10.1590/S0102-64452001000200006
Abstract: situated at opposed poles of the ideological and cultural life in the twenties and thirties of the last century. walter benjamin and carl schmitt are protagonists in a complex play of affinity and repulsion on the level of their basic conceptions, which are built around the theme of excess. the author proposes an hermeneutic of excess.
Doris Salcedo: Shibboleth
Annie Tse
Opticon1826 , 2008, DOI: 10.5334/opt.040821
Abstract: Doris Salcedo’s Shibboleth begins with an inconspicuous crack at the entrance of Tate Modern, inviting the viewer to follow its meandering course which runs 167 meters down the full length of the Turbine Hall. This encourages visitors to walk meditatively along the widening chasm, in contrast to a very different journey down Carsten Holler’s slides in a previous exhibition last year, also in the Turbine Hall, where all thought was suspended during the exhilarating descent. Shibboleth is groundbreaking – not only in the literal sense but also because it is the first time in Tate Modern’s history that a work of art has been embedded in the building itself, leaving a permanent mark after the crack is filled at the end of the exhibition in April.
Anne Renoult, Andrée Viollis, Une femme journaliste
Annie Rouquier
Genre & Histoire , 2008,
Abstract: Andrée Viollis (1870-1950), une des journalistes les plus connues entre les deux guerres, figure marquante de l'information et du grand reportage, témoin de nombreux événements politiques de la scène planétaire pendant le premier XXe siècle, est tombée aujourd'hui dans l'oubli ou presque, au contraire d'un Albert Londres, auquel on pourrait la comparer. Anne Renoult mène une enquête biographique, sollicitée par la double problématique du succès et de l'oubli et guidée par le parcours prof...
Robert Delpire : l’art d’un éditeur d’art
Annie Renonciat
Strenae : Recherches sur les Livres et Objets Culturels de l'Enfance , 2010, DOI: 10.4000/strenae.72
Abstract: évoquant récemment son métier d’éditeur d’ouvrages photographiques dans le Journal des arts, à propos du livre de William Klein sur New York qu’il a publié en 1956, Robert Delpire mettait l’accent sur le r le décisionnaire du photographe en minimisant le sien : Je crois que le métier d’éditeur est modeste. Il y a un artiste d’un c té, un artisan de l’autre, il ne faut jamais trahir cette relation. L’un des objectifs de notre dossier thématique vise précisément à examiner cette relation, m...

Buried hurts and colliding dreams in Yvonne Vera’s Butterfly Burning = Feridas escondidas e sonhos conflitantes em Butterfly Burning de Yvonne Vera
Annie Gagiano
Acta Scientiarum : Language and Culture , 2009,
Abstract: Zimbabwean author Yvonne Vera’s Butterfly Burning (1998) depicts anintense and tragically concluded love relationship between a middle-aged colonised male labourer, Fumbatha, and an idealistic and much younger woman, Phephelaphi. The context is the ghetto adjoining the city of Bulawayo in late colonial Southern Rhodesia. The articleemploys the concepts of genealogies and of transmodernity to delineate Vera’s reinscription of colonised African men and women in her illocutionary, densely poetic account of the growth of modernity in Africa, tragic because (despite similar, buried hurts) theprotagonists’ dreams are at odds. O romance Butterfly Burning (1998), da autora zimbabuana Yvonne Veramostra o relacionamento amoroso, intenso e trágico, entre Fumbatha, um trabalhador colonizado de meia idade, e Phephelaphi, uma mulher jovem e idealista. O contexto do enredo é o gueto perto da cidade de Bulawayo na ex-col nia da Rodésia do Sul. O artigo emprega os conceitos de genealogias e da transmodernidade para delinear as re-inscri es dos africanos e africanas colonizados em sua narra o ilocucionária, profundamente poética, do desenvolvimento da modernidade na áfrica. é também trágica (apesar da semelhan a dasferidas escondidas) pela n o-coincidência dos sonhos dos protagonistas.
