Identity in the novels of Marcio Veloz Maggiolo
No full text(in English): The aim of this diploma thesis is to analyse the Dominican identity in the works of the Dominican author Marcio Veloz Maggiolo. At first, the thesis briefly summarizes the evolution of the Dominican literature and mentions its most significant figures. Secondly, it deals with the evolution of the dominicaness from the colonial period up to the present and explains the reasons of the rooted antihaitianism. The second part consists of a detailed analysis of the novels The Diffuse Biography of Sombra Castañeda and The Accordion Man by Marcio Veloz Maggiolo, emphasizing the symbols of the official government's discourse, and also a more opened perspective of the dominicaness

Síntese de zeólita tipo 4A a partir de resíduo proveniente do processo de polpamento de papel branco
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia Química, Florianópolis, 2013.O crescente desenvolvimento industrial vem aumentando consideravelmente a quantidade de resíduos produzidos nos processos de fabricação e, entre esses, pode ser citado o segmento de papel e celulose. Os resíduos deste segmento, quando não dispostos de forma correta no meio ambiente, podem trazer sérios problemas à saúde pública. Além da disposição correta, há uma preocupação crescente com relação ao reaproveitamento destes resíduos para que possam ser reutilizados em outros processos industriais. Quando ocorre a reutilização, diminui de forma considerável a disposição em aterros e, via de regra, economiza energia, matéria prima e minimiza ainda a responsabilidade solidária da empresa geradora destes resíduos com a empresa depositante. Assim, este trabalho tem como foco principal o estudo e definição de uma rota eficaz e viável para a síntese de zeólitas a partir de resíduos provenientes do processo de polpamento de papel branco. Esta alternativa vem no sentido de diminuir os impactos ambientais que este tipo de resíduo gera quando descartado. A alternativa estudada é a utilização do caulim presente nestes resíduos como fonte de metacaulim para a produção de zeólitas. Estas zeólitas têm uma vasta aplicação como trocadores iônicos, catalisadores e peneiras moleculares. Os resultados demonstraram que a rota por meio de reação hidrotermal desenvolvida para a síntese de zeólitas tipo 4A é eficaz. A zeólita sintetizada a partir do resíduo proveniente do processo de polpamento de papel branco foi comparada com uma zeólita comercial padrão, obtendo-se resultados promissores.Abstract : The growing industrial development has considerably increased the amount of waste produced in industrial processes as in the cellulose and paper segment. The residues of this segment, if not properly disposed in the environment, can cause serious problems to public health. Besides the proper disposal of waste on the environment, there is growing concern about the reuse of this waste so that they can be reused in other industrial processes. When reuse occurs, decreases considerably the disposal in landfills and normally saves energy, raw materials and minimizes the responsibility of the company producer of these residues with the company depositor. This work has as main goal the study and development of a viable and effective route for the synthesis of zeolites from waste from the process pulping of white paper. This alternative comes in order to reduce the environmental impacts that this type of waste generated when discarded. The alternative studied is the use of kaolin present in the waste as a source of metakaolin to produce zeolites. These zeolites have a wide application as ion exchangers, catalysts and molecular sieves. The results demonstrated that t he route by hydrothermal reaction developed for the synthesis of type 4A zeolite is effective. The zeolite synthesized from waste from the process pulping of white paper was compared with a standard commercial zeolite and obtained excellent results. Adsorption experiments were performed to verify its efficiency in application as adsorbent of heavy metals from acid mine drainage in removing iron and manganese ions. The synthesized zeolite was extremely efficient in its use as an adsorbent

Systematic reviews with language restrictions and no author contact have lower overall credibility: a methodology study

In this study, we evaluated the association between two steps in the conduct of an SR – restricting the search to English, and author contact for missing data – and the overall credibility of a SR.Methods: All SRs cited by the Endocrine Society's Clinical Practice Guidelines published from October 2006 through January 2012 were included. The main outcome was the overall A Measurement Tool to Assess Systematic Reviews (AMSTAR) score, as a surrogate of SR credibility. Nonparametric Kruskal–Wallis tests and multivariable linear regression models were used to investigate the association between language restriction, author contact for missing data, and the overall AMSTAR score.Results: In all, 69 SRs were included in the analysis. Only 31 SRs (45%) reported searching non-English literature, with an average AMSTAR score of 7.90 (standard deviation [SD] =1.64). SRs that reported language restriction received significantly lower AMSTAR scores (mean =5.25, SD =2.32) (P<0.001). Only 30 SRs (43%) reported contacting authors for missing data, and these received, on average, 2.59 more AMSTAR points (SD =1.95) than those who did not (P<0.001). In multivariable analyses, AMSTAR score was significantly correlated with language restriction (beta =-1.31, 95% confidence interval [CI]: -2.62, -0.01, P=0.05) and author contact for missing data (beta =2.16, 95% CI: 0.91, 3.41, P=0.001). However, after adjusting for compliance with reporting guidelines, language restriction was no longer significantly associated with the AMSTAR score.Conclusion: Fewer than half of the SRs conducted to support the clinical practice guidelines we examined reported contacting study authors or searched non–English literature. SRs that did not conduct these two steps had lower quality scores, suggesting the importance of these two steps for overall SR credibility.Keywords: evidence-based medicine, research design, validity, quality of evidenc

Pará: Parauapebas. Roraima: Amajari, Uiramutã (Figure 15C). Etymology The specific epithet honours the ‘Yanomami’, the name for an ethnic group of South American natives, used here as a noun in apposition. The ‘Yanomami’ comprise a society of hunter-agriculturists of the tropical rainforest of northern Amazonia, whose contact with non-indigenous society over most of their territory has been relatively recent. Their territory covers an area of approximately 192,000 km 2, located on both sides of the border between Brazil and Venezuela, in the Orinoco– Amazon interfluvial region (affluents of the right shore of the Rio Branco and left shore of the Rio Negro). The total population of the ‘Yanomami’ in Brazil and Venezuela is today estimated to be around 26,000 people (Albert 1999). The byroni species group Diagnosis The byroni group includes M. atlantica Santos & Silveira, M. guarani sp. n., M. xavante sp. n., M. mapinguari sp. n., M. purpurata Smith, M. karitiana sp. n. and additional species previously placed in the subgenus Megalopta (Noctoraptor) Engel, Brooks and Yanega. It is distinguished from other species groups by the ocellocular distance equal to length of F1 and by the sparsely punctured mesoscutum posteriorly to mesoscutal lip (≥ 1 pd). The female differs from those of other groups by lacking the mandibular subapical and supplementary teeth and the basal macula in the inner surface of the mandible. The male is characterized by the F2 as wide as about twothirds of F3, dorsal surface of flagellomeres flattened to slightly depressed and by the protruding process of S4, in lateral view, digitiform or triangular and short. It is shown here that this group also contains species with a metallic green integument, differing from the previously described dark brown non-metallic species. Bees in this group are rarely collected and most species are known from single specimens or small series. All known females in the byroni group have a morphology associated with non nest-making, parasitic behaviour. Biani and Wcislo (2007), in their work on M. byroni, consider that this group might behave as obligatory cleptoparasites or social parasites. Taking into consideration that female morphology in this group is more similar to that of macrocephalic females of nest-making species, it is more plausible to believe that they behave as social parasites. Macrocephalic females exhibit dominant queen-like behaviour over the non macrocephalic subordinate females.Published as part of Santos, L. M. & Melo, G. A.
