Synthesis, characterization and antibacterial screening of some Schiff bases derived from pyrazole and 4-amino antipyrine
No full textSome Schiff bases of pyrazole and 4-amino antipyrine have been synthesized. The antibacterial screening of these synthesized compounds was done in dimethyl forma-mide against four Gram positive bacteria viz. Bacillus cereus, Staphylococcus aureus, Staphylococcus epidermidids and Micrococcus luteus, and three Gram negative bacteria viz. Proteus mirabilis, Escherichia coli and Klebsiella aerogenes. It is observed that in comparison to Schiff bases of 4-amino antipyrine, pyrazole Schiff bases are better for inhibition for these selected Gram positive and Gram negative bacterial strains.Se sintetizaron algunas bases de Schiff a partir de pirazol y 4-amino antipirina. La evaluación de la actividad antibacteriana de estos compuestos en dimetil formamida se realizó frente a cuatro bacterias Gram positivas, Bacillus cereus, Staphylococcus aureus, Staphylococcus epidermidids y Micrococcus luteus, y frente a tres bacterias Gram negativas, Proteus mirabilis, Escherichia coli y Klebsiella aerogenes. Se observó mejor inhibición bacteriana frente a las diferentes cepas para las bases de Schiff basadas en pirazol comparadas con aquellas basadas en 4-amino antipirina
Synthesis, characterization and in vitro antimicrobial screening studies of some pyridyl-coumarin compounds
No full textLa actividad antimicrobiana in vitro de algunos compuestos derivados de piridil-coumarina se evaluó frente a algunas cepas bacterianas y fúngicas en DMF y DMSO. Las piridil-cumarinas se sintetizaron en el laboratorio y sus estructuras se confirmaron por diferentes técnicas espectroscópicas, tales como IR, 1H NMR, 13C NMR y masas. Algunos de los compuestos que se obtuvieron presentaron buena actividad antibacteriana en ambos solventes. </jats:p
Racializing white residues: seditious Anglo-Indians and others
No full textMy dissertation interrogates the discursive residues of the Anglo-Indian question in decolonized India. To problematize these residues, I structure my dissertation as a fragmented genealogy of colonial and post-colonial perceptions of Anglo-Indians. I open my dissertation by showing how, since the late-nineteenth century, Anglo-Indians were claimed to be only of part-European racial provenance, and tautologically had their bodies deemed sexually deviant. Their bodies being, like those of their non-Anglo-Indian counterparts, in fact of uncertain racial intermixture, I argue that Anglo-Indians inhabit mongrel bodies—bodies in a state of continual flux of class and race, inhabiting a multiplicity of pluralized communities. The ethical end of the decolonized Indian nation-state, I accordingly suggest, is to facilitate the recognition of mongrelism as an inevitable phenomenon across groups—one that fractures monolithic conceptions of race and community. To flesh out this argument, I conduct readings from an archive of novels, historiographic treatises, short stories, memoirs, films, and cartoons. The figures whose texts I examine include, among others, colonial Anglo-Indian ‘prostitute’ Amelia Horne, Anglo-Indian anti-racism activist Cedric Dover, Bengali novelist Sharadindu Bandyopadhyay, diasporic English writer Aubrey Menen, Indian cartoonist Mario Miranda, Bengali film director Satyajit Ray, Anglo-Indian politician and historiographer Frank Anthony, and British-Indian writer Ruskin Bond.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2020-08-01The student, Debojoy Chanda, accepted the attached license on 2018-07-04 at 01:48.The student, Debojoy Chanda, submitted this Dissertation for approval on 2018-07-04 at 02:33.This Dissertation was approved for publication on 2018-07-06 at 10:04.DSpace SAF Submission Ingestion Package generated from Vireo submission #12728 on 2018-09-27 at 11:16:29Made available in DSpace on 2018-09-27T16:30:17Z (GMT).

Content delivery in software defined networks
No full textInformation Centric Architectures view content as the narrow waist of the networking stack. This abstraction allows routing based on the content name, rather than the network locator of the content consumer and producer. We present ContentFlow, an Information Centric network architecture which supports content routing by mapping the content name to a OpenFlow de ned ow based on TCP and IP semantics. And, thus enables the use of OpenFlow switches to achieve content routing over a legacy IP architecture. ContentFlow is viewed as an evolutionary step between the current IP networking architecture, and a full edged ICN architecture. It supports content man- agement, content caching and content routing at the network layer, while using a legacy OpenFlow infrastructure and a modi ed controller. By e ciently using the content in- formation available in the network, ContentFlow supports e cient tra c engineering. Also, ContentFlow is transparent from the point of view of the client and the server, and can be inserted in between without modi cation at either end. The architecture and implementation of ContentFlow on top of the existing OpenFlow software de ned networking framework is described. Performance of ContentFlow is evaluated using a prototype implementation of an enterprise SDN network with Floodlight controller and multiple virtualized OpenFlow switches. The results show that ContentFlow does result in reduced content access delay in comparison to a legacy architectures.M.S.Includes bibliographical referencesby Abhishek Chand
Antibacterial and phytochemical studies on twelve species of Indian medicinal plants
No full textThe aqueous and methanol extracts of 12 plants each belonging to
different families were evaluated for antibacterial activity against
medically important bacteria viz. B. cereus ATCC11778 , S. epidermidids
ATCC12228 , E. aerogenes ATCC13048, P. vulgaris NCTC 8313, S.
typhimurium ATCC 23564. The in vitro antibacterial activity was
performed by agar disc diffusion and agar well diffusion method. The
aqueous extracts were inactive but methanol extracts showed some degree
of antibacterial activity against the tested bacterial strains. S.
typhimurium was the most resistant bacteria while B. cereus was the
most susceptible bacteria. Amongst the plant species screened, methanol
extract of Bauhinia variegata bark showed best antibacterial activity
