O jogo de intermediações enunciativas no romance de Alan Pauls

The novel O passado (2003) by Alan Pauls presents many isotopies which would deserve to be investigated: there is a varied construction of loving relationships among the characters, who reveal different feelings, that would allow a mapping of passions to be studied; there is an activity of translation (role performed by Rimini and Carmen) that engenders a very rich reflection on the literary activity which is taking place. There is also the presence of a visual artist, Jeremy Riltse, revealing a poetic work which was created by this discourse. Due to the dimension that a research of this kind would require, it is not possible to deal with all the isotopies. Thus, the last one was chosen to be investigated, that is, to verify how the fictional visual artist and his singular work operate in the novel.

Cecília Meireles, leitora de poesia portuguesa

In the early XX century scene, the poem writer Cecilia Meireles was the voice of the Portuguese Literature in Brazil. Probably as the writer´s fi rst husband, the Portuguese artist Fernando Dias, was in contact with the intellectuals from the Portuguese cultural universe, Cecilia certainly had access to Portuguese publishing before they were popular in Brazil. So, by printing, in 1944 the anthology Poetas novos de Portugal, by Dois Mundos Publishing house (directed by Jaime Cortesão), Cecília could spread the Portuguese poetry which had never been published in books in our country. As it has never been printed again, the anthology shows a detailed view about the Portuguese literature scene at that time. My work aims at looking thoroughly this volume, in order to understand the criteria used by Cecilia when selecting the authors and poems, in the light of such piece indicates certain understanding of the Portuguese Literature relations with Brazil.

Desenvolvimento, implantação e avaliação do desempenho de biorreator anaeróbico de leito fluidizado e leito fixo com filtros biológicos em materiais diversos

This study aimed to develop, implement and evaluate the performance of a new type of bioreactor for anaerobic treatment of wastewater using different filling materials like trickling filters post-reactor. This bioreactor has mixed characteristics of the UASB reactors and horizontal flow from the point of view of removal of BOD (Biochemical Oxygen Demand) ssed (settled solids), TS (Total Solids), SS (Suspended Solid), SD (Dissolved Solids) and turbidity. The experimental model consists of a bioreactor with a volume of 12 m³, 2/3 filled by fluidized bed and 1/3 for fixed. The fluidized bed is made of polystyrene plates used as a system percolation and compartmentalized trickling filters, where each compartment was filled with a support medium with different characteristics (gravel number 4, plastic rings of polystyrene, PET and HDPE) . In addition, the output of a filter system was installed three entries filled with activated carbon. The bioreactor was installed in private residence in the city of Igarapava-SP (20° 02'40.18"S and 47° 45'01.36" W). The system was highly efficient as the removal of organic contaminant load 92% on average reducing the BOD, a significant result when compared to other anaerobic systems. For the other parameters, the mean reduction was 96% for turbidity, 99% ssed, 67.5% ST, 57% SD and 88% of SS. As for its operation the system was capable of operating in continuous flow without the need for maintenance during the entire period of evaluation and without energy, as it operates taking advantage of the natural slope of the terrain where it is installed. The environmental impacts were minimized due to the preservation of local vegetation allowing the ecosystem to remain unchanged beyond the prototype was completely sealed preventing exhalation of odors and therefore not causing inconvenience to neighboring populations. Given these facts it was concluded that the prototype is shown to be highly feasible deployed as a new alternative for treatment of sewage in rural and urban settings (individual homes, condos, farms, ranches, etc.) Due to ease of design and operability, and sustainability at all stages of execution.

Propagação de rambutanzeiro (Nephelium lappaceum L.) por enxertia

There is great genetic diversity of rambutan plants, thus, to establish commercial orchards culture, it is recommended the use of plants vegetatively propagated. Therefore, this research aimed to determine the best method of grafting, graft protection and type of rootstock for its propagation. The experiment was repeated in two seasons (autumn/winter and spring/summer). The experimental design was completely randomized in both experiments, with four replicates, each experimental unit consisted of 10 plants analyzed in a 4x2x2 factorial with four types of grafting (whip graft-WG; cleft graft -CG; wedge graft-WG; and inverted wedge graft-IWG;), 2 types of graft protection (Biodegradable and plastic) and 2 types of rootstock (without or with leaves). The variables analyzed in this study were: percentage of grafting success, number and length of buds (cm). For grafting performed in autumn /winter, both by cleft grafting as whip graft with biodegradable strip and rootstock leafless provided the best results in propagation of rambutan tree. The best results were observed during the autumn / winter.

Radiação gama na conservação de caqui 'Giombo', destanizado e frigoarmazenado

O caqui apresenta uma safra curta, sendo necessário estender seu período de comercialização utilizando técnicas adequadas de armazenamento. O objetivo deste trabalho foi avaliar o uso da radiação gama na qualidade pós-colheita de caquis 'Giombo' destanizados. Frutos colhidos meio-maduros e com aproximadamente 50 % da coloração verde, foram destanizados, acondicionados em bandejas de poliestireno expandido (EPS), revestidas por filme plástico de polietileno de baixa densidade (PEBD) e submetidos à radiação gama (60Co). Os frutos foram armazenados durante 35 dias, sob refrigeração (0±0,5 ºC e 85 ± 0,5% UR). Os tratamentos realizados foram: T1 - 0,0 kGy; T2 - 0,3 kGy; T3 - 0,6 kGy; T4 - 0,9 kGy; T5 - 1,2 kGy. As análises realizadas a cada 7 dias foram: perda de massa, atividade respiratória, teores de sólidos solúveis (SS), ácido ascórbico, acidez titulável (AT) e relação SS/AT. Os frutos submetidos à dose de 0,6 kGy apresentaram o menor percentual de perda de massa e produção de CO2 ao longo do período experimental. Os teores de SS e AT permaneceram estáveis e sem diferenças devido às doses de irradiação aplicadas. Os tratamentos com 0,3 KGy e 0,6 KGy foram os mais eficazes na manutenção da firmeza nos caquis. Nos teores de ácido ascórbico, observou-se redução ao longo do período experimental, sendo os menores valores apresentados para a maior dose de irradiação (1,2 KGy).

Root canal filling: fracture strength of fiber-reinforced composite-restored roots and finite element analysis

The aims of this study were to evaluate the effect of root canal filling techniques on root fracture resistance and to analyze, by finite element analysis (FEA), the expansion of the endodontic sealer in two different root canal techniques. Thirty single-rooted human teeth were instrumented with rotary files to a standardized working length of 14 mm. The specimens were embedded in acrylic resin using plastic cylinders as molds, and allocated into 3 groups (n=10): G(lateral) - lateral condensation; G(single-cone) - single cone; G(tagger) - Tagger's hybrid technique. The root canals were prepared to a length of 11 mm with the #3 preparation bur of a tapered glass fiber-reinforced composite post system. All roots received glass fiber posts, which were adhesively cemented and a composite resin core was built. All groups were subjected to a fracture strength test (1 mm/min, 45°). Data were analyzed statistically by one-way ANOVA with a significance level of 5%. FEA was performed using two models: one simulated lateral condensation and Tagger's hybrid technique, and the other one simulated the single-cone technique. The second model was designed with an amount of gutta-percha two times smaller and a sealer layer two times thicker than the first model. The results were analyzed using von Mises stress criteria. One-way ANOVA indicated that the root canal filling technique affected the fracture strength (p=0.004). The G(lateral) and G(tagger) produced similar fracture strength values, while G(single-cone) showed the lowest values. The FEA showed that the single-cone model generated higher stress in the root canal walls. Sealer thickness seems to influence the fracture strength of restored endodontically treated teeth.
