O jornalismo em O tempo e o vento: fonte histórica e discurso ideológico na República Velha
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em LiteraturaOs recursos do jornalismo presentes no romance O Tempo e o Vento, de Erico Verissimo, são objetos de análise desta pesquisa. O estudo é direcionado à prática jornalística presente nos episódios que se concentram nos primeiros anos do governo republicano no Brasil. Ao explorar as notícias enquanto fontes históricas no romance, bem como os personagens-jornalistas e os principais jornais representados, busca-se interpretar os aspectos sociais reproduzidos na trilogia e suas articulações com o discurso da imprensa. A pesquisa tem por objetivo revelar como a versão jornalística do fato histórico, apoiada em pressupostos ideológicos, influencia a estética de O Tempo e o Vento
Filho de tigre sai pintado: medicina, hereditariedade e identidade nacional em textos de Erico Verríssimo
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em História, Florianópolis, 2009Busquei compreender de que forma textos de Erico Verissimo (década de 1930) dialogaram com temas correntes das medicinas higienista e eugenista, das quais tradicionalmente se enfatizam aspectos autoritários e vinculação ao Estado Novo. O autor utilizou premissas médicas para apontar soluções a desequilíbrios sociais em seus textos, assim como uma profusão de imagens de decomposição, degeneração, decadência física e do meio. Em seus livros, o oposto da doença (física e social), mais que a saúde, parece ser a medicina. Uma aparente contradição se apresenta, pois o autor sempre se destacou pela crítica à arbitrariedade e ao autoritarismo. Nesse sentido, abordei o debate sobre adesões de artistas e intelectuais a projetos governamentais na era Vargas, entendendo que suas motivações foram variadas. Da mesma forma, tratei do destaque dado a saúde - desde as campanhas higienistas -, educação e literatura na construção da identidade nacional, convergindo na preocupação com o futuro das novas gerações. Premissas filosóficas e científicas do século 19 e a literatura naturalista de Émile Zola também foram analisadas, pois abriram espaço definitivo para a compreensão do mundo e intervenção social, essenciais às elaborações científicas e artísticas das primeiras décadas do século 20
Microencapsulation by spray drying of a functional product with mixed juice of acerola and ciriguela fruits containing three probiotic lactobacilli
No full textMicroencapsulation of probiotic bacteria with fruit juice can be a good alternative for new probiotic foodstuff production mainly for people with galactosemia and lactose intolerance. The aim of this study was to encapsulate three probiotic bacteria, namely Lactobacillus rhamnosus, Lactobacillus casei and Lactobacillus plantarum, with a 40:60% (w/w) mixed juice of acerola and ciriguela by spray drying at air inlet temperature of 140 °C, 0.60 L/h feed flow rate and 10% (w/w) maltodextrin, as well as to evaluate the influence of maltodextrin dextrose equivalent (DE) value (5, 10 and 15) on microcapsules’ properties. Powders produced were characterized in terms of cell viability counts before and after microencapsulation, physicochemical property analyses and sensory properties. Although spray drying caused a reduction of 2 decimal logarithm units in the number of viable cells, all powders had probiotic cell counts higher than that required for probiotic foods (106 CFU/g). All the three maltodextrins tested were feasible to obtain powders with satisfactory probiotic viability, physicochemical and sensory properties, thereby demonstrating that they are promising materials to microencapsulate probiotic bacteria in fruit juices
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The Critic Jose Verissimo: Perspectives of the Interpretation
No full textPublished in 1916 and written in most of the literary life of Jose Verissimo, the History of Brazilian Literature: from Bento Teixeira (1602) to Machado de Assis (1908) gathers the several activities of the critic from Para as an active intellectual. With the objective of making a reflection on the facets of the critic and literary historian, this essay analyzes his work of interpretation of the Brazilian nation, through the approximation between the various discourses that make up History. especially literature and education. In proposing the definition of these perspectives, it is noted that the final work of Jose Verissimo has an organicity and a refinement of his analysis criteria.Univ Estadual Paulista, UNESP, Assis, SP, BrazilUniv Estadual Paulista, UNESP, Assis, SP, Brazi

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Formation Of Catalyst Nanoparticles And Nucleation Of Carbon Nanotubes In Chemical Vapor Deposition
No full textMulti-walled carbon nanotubes and other carbon nanostructures have been grown using catalytic thermal chemical vapor deposition method in a horizontal tubular quartz furnace at atmospheric pressure. The mechanisms of nanotubes/nanofibers nucleation and growth are analyzed. A new model explaining the nanotube nucleation as a specific instability occurring on the catalyst particle surface supersaturated with carbon is presented. It is also shown that an axially symmetric instability, giving rise to the nanotube nucleation, is developed when certain critical conditions such as temperature, supersaturation and catalyst volume are achieved. For smaller temperatures, another mechanism of carbon segregation from supersaturated catalyst particles has been observed. In this case, flat rather than tubular graphitic layers are formed. These findings are important for better understanding and control of the synthesis of different carbon nanoforms using chemical vapor deposition.
