Autodepuração do igarapé Santa Isabel no município de Santa Isabel do Pará - aplicação do modelo de Streeter-Phelps

A presente pesquisa realiza-se em Santa Isabel do Pará. Foi avaliada a autodepuração do igarapé homônimo através da modelagem matemática proposta por Streeter-Phelps (1925). Para isso, durante o período de outubro de 2009 e setembro de 2010, foram analisados os parâmetros físico-químicos OD e DBO e determinadas as variáveis hidráulicas em 11 pontos amostrais, subdividindo em 4 seções o curso d’água. O resultado da modelagem indicou que os trechos 1 e 2 possuem deficiência na autodepuração, pois não obedecem os padrões da legislação CONAMA 357/05. Por fim, ressalta-se ainda que, além de desfavorável capacidade de resiliência que o Igarapé Santa Isabel possui, não há uma atuação efetiva dos órgãos ambientais responsáveis pela fiscalização da qualidade deste recurso hídrico para que haja o controle das quantidades de poluentes lançadas no igarapé. Desta forma, pode-se evitar que, em um cenário futuro, graves problemas, devido aos usos múltiplos das águas deste manancial, venham prejudicar a saúde e o bem estar das populações dependentes do Igarapé Santa Isabel.

"Dar voce a una voce": diversità e rappresentazione nella letteratura young adult. Proposta di traduzione di Gabi, a Girl in Pieces di Isabel Quintero.

In this dissertation, I will present my translation into Italian of several excerpts from Gabi, A Girl in Pieces, a young adult (YA) novel by Mexican-American author Isabel Quintero, along with examining the issues of diversity and representation in YA literature. This study aims to demonstrate the benefits of multicultural literature for young readers and the importance of publishing stories that reflect the diversity of the world we inhabit. The translation of the novel is accompanied by an analysis of its social, cultural, and literary context. The first chapter provides an overview of Chican@ history, literature, and culture, focusing on the concepts of identity and hybridity. The second chapter describes YA literature and its characteristics, outlines its history, and discusses the value of diverse books in the lives of teenage readers. Additionally, it cites relevant studies and statistics proving the dearth of diverse literature for young readers in the United States. The third chapter focuses specifically on the representation of Latin@s and Chican@s in literature for young readers, examining the main stereotypes that have plagued the depiction of this community and the new perspectives offered by Mexican-American YA authors. In the fourth chapter, I introduce Isabel Quintero and her novel Gabi, A Girl in Pieces, analyzing its plot, style, format, and main themes. In the fifth chapter, I provide my translation, which is then analyzed in the sixth and final chapter. The translation commentary details some of the problems I encountered and the strategies I applied. The sixth chapter also includes some observations on the translation of teenage speech, of multilingual texts, and of children’s and YA literature.

Detrital Zircon Evidence for Non-Laurentian Provenance, Mesoproterozoic (ca. 1490-1450 Ma) Deposition and Orogenesis in a Reconstructed Orogenic Belt, Northern New Mexico, USA: Defining the Picuris Orogeny

Detrital zircon and igneous zircon U-Pb ages are reported from Proterozoic metamorphic rocks in northern New Mexico. These data give new insight into the provenance and depositional age of a >3-km-thick metasedimentary succession and help resolve the timing of orogenesis within an area of overlapping accretionary orogens and thermal events related to the Proterozoic tectonic evolution of southwest Laurentia. Three samples from the Paleoproterozoic Vadito Group yield narrow, unimodal detrital zircon age spectra with peak ages near 1710 Ma. Igneous rocks that intrude the Vadito Group include the Cerro Alto metadacite, the Picuris Pueblo granite, and the Penasco quartz monzonite and yield crystallization ages of 1710 +/- 10 Ma, 1699 +/- 3 Ma, and 1450 +/- 10 Ma, respectively. Within the overlying Hondo Group, a metamorphosed tuff layer from the Pilar Formation yields an age of 1488 +/- 6 Ma and represents the first direct depositional age constraint on any part of the Proterozoic metasedimentary succession in northern New Mexico. Detrital zircon from the overlying Piedra Lumbre Formation yield a minimum age peak of 1475 Ma, and similar to 60 grains (similar to 25%) yield ages between 1500 Ma and 1600 Ma, possibly representing non-Laurentian detritus originating from Australia and/or Antarctica. Detrital zircons from the basal metaconglomerate and the middle quartzite member of the Marquenas Formation yield minimum age peaks of 1472 Ma and 1471 Ma, consistent with earlier results. We interpret the onset of ca. 1490-1450 Ma deposition followed by tectonic burial, regional Al2SiO5 triple-point metamorphism, and ductile deformation at depths of 12-18 km to reflect a Mesoproterozoic contractional orogenic event, possibly related to the final suturing of the Mazatzal crustal province to the southern margin of Laurentia. We propose to call this event the Picuris orogeny.

Trypanosoma congolense procyclins: unmasking cryptic major surface glycoproteins in procyclic forms

In the tsetse fly, the protozoan parasite Trypanosoma congolense is covered by a dense layer of glycosylphosphatidylinositol (GPI)-anchored molecules. These include a protease-resistant surface molecule (PRS), which is expressed by procyclic forms early in infection, and a glutamic acid- and alanine-rich protein (GARP), which appears at later stages. Since neither of these surface antigens is expressed at intermediate stages, we investigated whether a GPI-anchored protein of 50 to 58 kDa, previously detected in procyclic culture forms, might constitute the coat of these parasites. We therefore partially purified the protein from T. congolense Kilifi procyclic forms, obtained an N-terminal amino acid sequence, and identified its gene. Detailed analyses showed that the mature protein consists almost exclusively of 13 heptapeptide repeats (EPGENGT). The protein is densely N glycosylated, with up to 13 high-mannose oligosaccharides ranging from Man(5)GlcNAc(2) to Man(9)GlcNAc(2) linked to the peptide repeats. The lipid moiety of the glycosylphosphatidylinositol is composed of sn-1-stearoyl-2-lyso-glycerol-3-HPO(4)-1-(2-O-acyl)-d-myo-inositol. Heavily glycosylated proteins with similar repeats were subsequently identified in T. congolense Savannah procyclic forms. Collectively, this group of proteins was named T. congolense procyclins to reflect their relationship to the EP and GPEET procyclins of T. brucei. Using an antiserum raised against the EPGENGT repeat, we show that T. congolense procyclins are expressed continuously in the fly midgut and thus form the surface coat of cells that are negative for both PRS and GARP.

Die Mehrstimmige Messe im ‘Goldenen Jahrhundert’. Überlieferung und Repertoirebildung in Quellen aus Spanien und Portugal (ca. 1490-1630)

Das Studium der Überlieferung und Repertoirbildung gibt über die Art der Nutzung von musikalischen Werken Aufschluss. Im iberischen Raum wurde im 16. Jh. das internationale Messenrepertoire aus Italien und Flamen ausgiebig genutzt, doch waren die kommerziellen Wege für die Beziehung wichtiger als politische Allianzen.

Allogeneic haematopoietic stem cell transplantation for mitochondrial neurogastrointestinal encephalomyopathy.

Haematopoietic stem cell transplantation has been proposed as treatment for mitochondrial neurogastrointestinal encephalomyopathy, a rare fatal autosomal recessive disease due to TYMP mutations that result in thymidine phosphorylase deficiency. We conducted a retrospective analysis of all known patients suffering from mitochondrial neurogastrointestinal encephalomyopathy who underwent allogeneic haematopoietic stem cell transplantation between 2005 and 2011. Twenty-four patients, 11 males and 13 females, median age 25 years (range 10-41 years) treated with haematopoietic stem cell transplantation from related (n = 9) or unrelated donors (n = 15) in 15 institutions worldwide were analysed for outcome and its associated factors. Overall, 9 of 24 patients (37.5%) were alive at last follow-up with a median follow-up of these surviving patients of 1430 days. Deaths were attributed to transplant in nine (including two after a second transplant due to graft failure), and to mitochondrial neurogastrointestinal encephalomyopathy in six patients. Thymidine phosphorylase activity rose from undetectable to normal levels (median 697 nmol/h/mg protein, range 262-1285) in all survivors. Seven patients (29%) who were engrafted and living more than 2 years after transplantation, showed improvement of body mass index, gastrointestinal manifestations, and peripheral neuropathy. Univariate statistical analysis demonstrated that survival was associated with two defined pre-transplant characteristics: human leukocyte antigen match (10/10 versus <10/10) and disease characteristics (liver disease, history of gastrointestinal pseudo-obstruction or both). Allogeneic haematopoietic stem cell transplantation can restore thymidine phosphorylase enzyme function in patients with mitochondrial neurogastrointestinal encephalomyopathy and improve clinical manifestations of mitochondrial neurogastrointestinal encephalomyopathy in the long term. Allogeneic haematopoietic stem cell transplantation should be considered for selected patients with an optimal donor.
