Descida poetica no mundo infernal de Cruz e Sousa e Baudelaire
Get PDFDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e ExpressãoEste estudo, um trabalho temático sobre a questão do satanismo, pretende mostrar as relações intertextuais da obra de dois escritores, o brasileiro João da Cruz e Sousa e o francês Charles Baudelaire. Trata-se, ao longo do estudo, de tentar provar minha hipótese de trabalho: que ambos os poetas se basearam em 'princípios satânicos' no momento do ato da criação. Isto me levou a estabelecer a existência de uma teoria satânica no âmbito de suas poesias, marcando assim o início da poesia moderna
Prevalence of Plasmid Mediated Quinolone Resistance Determinants among Oxyiminocephalosporin Resistant Enterobacteriaceae in Argentina.
Get PDFHigh quinolone resistance rates were observed among oxyiminocephalosporin resistant enterobacteria. In the present study, we searched for the prevalence of plasmid mediated quinolone resistance (PMQR) genes within the 55 oxyiminocephalosporin resistant enterobacteria collected in a previous survey. The main PMQR determinants were aac(6´)-Ib-cr and qnrB corresponding to 42.4% and 33.3%, respectively. aac(6?)-Ib-cr was more frequently present in CTX-M-15 producing isolates, while QnrB was homogeneously distributed in all CTX-M producers.Fil: Rincón Cruz, Giovanna.

Lack of cerebral BMAA in human cerebral cortex
No full textBioaccumulation of -methylamino-L-alanine (BMAA) through Cyanobacteria-contaminated food or water supplies has been suggested as a possible contributor to Parkinson-dementia complex (PDC) among the indigenous Chamorro of Guam as well as Alzheimer disease (AD) worldwide, a speculation that has been widely commented on in news and editorial sections of premier scientific and medical journals, and that has led to product recalls and government-sponsored assessments of public health in Europe. However, quantification of BMAA to date has been based on indirect high performance liquid chromatography methods. Given the potential global health significance, we developed a stable-isotope dilution assay for BMAA to more rigorously test its proposed bioaccumulation in cerebral cortex.Peer reviewedfinal article publishe

Specific epithet: —The name of the species refers to the General Juan N. Álvarez National Park, located near the city of Chilapa de Álvarez, Guerrero, in the Sierra Madre del Sur. The site was decreed a national park on May 14, 1964, by Adolfo López Mateos. Juan Nepomuceno Álvarez Hurtado (January 27, 1790 – August 21, 1867), was a military man from Guerrero who participated in armed conflicts of Mexico, especially in the war of independence until the overthrow of Emperor Maximiliano during the second French Intervention. He was also President of the Republic for a brief period in 1855.Published as part of Dorado, Óscar, Cruz-Durán, Ramiro & García, Rubí Bustamante, 2022, Two new closely related species of Brongniartia (Fabaceae, Faboideae) from the Sierra Madre del Sur in Guerrero, México, pp. 1-10 in Phytotaxa 544 (1) on pages 3-4, DOI: 10.11646/phytotaxa.544.1.1, http://zenodo.org/record/650132

Remarks: A. ferreirai from the Upper Carboniferous (Piedra Shotle Formation, Chubut) of Argentina, was originally attributed to the palaeodictyopterans but clearly exhibits characters typical for Taiophlebia, and can be therefore transferred to the latter genus.Published as part of Martins-Neto, R.

Estimating Dynamic Traffic Matrices by using Viable Routing Changes
Get PDFAbstract: In this paper we propose a new approach for dealing with the ill-posed nature of traffic matrix estimation. We present three solution enhancers: an algorithm for deliberately changing link weights to obtain additional information that can make the underlying linear system full rank; a cyclo-stationary model to capture both long-term and short-term traffic variability, and a method for estimating the variance of origin-destination (OD) flows. We show how these three elements can be combined into a comprehensive traffic matrix estimation procedure that dramatically reduces the errors compared to existing methods. We demonstrate that our variance estimates can be used to identify the elephant OD flows, and we thus propose a variant of our algorithm that addresses the problem of estimating only the heavy flows in a traffic matrix. One of our key findings is that by focusing only on heavy flows, we can simplify the measurement and estimation procedure so as to render it more practical. Although there is a tradeoff between practicality and accuracy, we find that increasing the rank is so helpful that we can nevertheless keep the average errors consistently below the 10% carrier target error rate. We validate the effectiveness of our methodology and the intuition behind it using commercial traffic matrix data from Sprint's Tier-1 backbon
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
