49. A produção do espaço intra-urbano de aparecida de Goiânia e a dinâmica metropolitana de Goiânia: de 1960 aos anos 2000
Aparecida de Goiânia é uma cidade que se desenvolve numa relação inextricável com Goiânia. O objetivo desta pesquisa foi justamente compreender a papel desta relação no processo de estruturação do espaço intra-urbano aparecidense. A questão central que norteou nossas análises foi: como se formou Aparecida de Goiânia? A esta pergunta seminal, so

50. A new host for Philornis torquans (Diptera, Muscidae) from the Brazilian Cerrado
Abstract Philornis larvae and pupae were collected in nestlings of Neothraupis fasciata (Lichtenstein), the White-banded Tanager (Passeriformes, Thraupidae), in three breeding seasons, between October and November 2003-2005 in a reserve in central Brazil. Here, we present biological data, diagnosis to the recognition of the species and a key to the segregati

51. A rare case of deafness and renal abnormalities in HDR syndrome caused by a de novo mutation in the GATA3 gene
Abstract HDR syndrome is a rare autosomal dominant disorder caused by mutations in the GATA3 gene and characterized by hypoparathyroidism, sensorineural deafness and renal abnormalities. Here we report a Brazilian family, from which the proband, his mother and his grandfather were diagnosed with bilateral sensorineural hearing loss. Molecular screening of th

52. Influence of High Current-Density Impulses on the Stress-Strain Response and Microstructural Evolution of the Single Crystal Superalloy CMSX-4
Owing to the low formability of single-crystal nickel-based materials, single-crystal components are typically cast. Subsequently, a multi-stage heat treatment is carried out in order to partially compensate the dendrite segregation and to stabilize the precipitated γ’-phase. Such components possess a high resistance to creep at elevated temperatures. Sin

53. Abiotic effects on the cover and richness of corticolous lichens on Araucaria angustifolia trunks
ABSTRACT Lichens play a key role in natural ecosystems, as they can function as primary producers, recycle minerals and fix nitrogen. Despite their environmental importance, little is known about lichen ecology in Brazil, and especially about how abiotic factors may influence their spatial distribution. In this study, we aimed to verify how the cover and ric

54. A globally applicable PCR-based detection and discrimination of BK and JC polyomaviruses
ABSTRACT BKV and JCV belong to the Polyomaviridae family and are opportunistic agents associated with complications in immunocompromised individuals. Although a single screening assay for both viruses would be convenient, the diversity of BKV and JCV serotypes and genotypes is a methodological challenge. In this paper, we developed a PCR method able to detec

55. Nectar dynamics and reproductive biology of Passiflora actinia Hook. (Passifloraceae) in Araucaria Forest
ABSTRACT Nectar production has an important role in pollinator attraction and successful fruit production in many self-incompatible angiosperm groups. The reproductive biology of Passiflora actinia was studied here and related to nectar dynamics. Passiflora actinia presented a temporal segregation of male and female functions at the beginning of anthesis. Du

56. Discriminación de Género en el Sistema Universitario Argentino
Abstract: Women are the majority both among the students and in the teaching staff at the Argentine universities. However, they appear grouped mainly in certain areas and barely access the higher upper categories. There is a horizontal and a vertical pattern of gender segregation. Our objective is to study the participation of women and to deepen the percept

57. Rheo-Squeeze Casting of High-Silicon Aluminium Alloy Pipes with Gradient Structures and Their Mechanical Properties
Three different compositions of high-Si Al alloy pipe, with a gradient structure, were produced through semi-solid rheological squeeze casting, the microstructural characteristics of which were investigated. The mechanism of gradient structure formation and the effect of acicular Fe-rich phases on liquid segregation were revealed. Meanwhile, the crystal stru

58. Designing a Microstructural Array Associated with Hardness of Dual-phase Cu-Zn Alloy Using Investment Casting
A comparative investigation on the microstructural morphologies and hardness values of Cu-35 wt.% Zn and Cu-30 wt.% Zn with 1.5 wt.% Al content is provided. Distinctive specimens by using traditional investment casting were produced. Specimens withdrawn from distinct locations along the castings were thermally and microstructural analyzed. Thermally and chem

59. Exploration of gene functions for esophageal squamous cell carcinoma using network-based guilt by association principle
Gene networks have been broadly used to predict gene functions based on guilt by association (GBA) principle. Thus, in order to better understand the molecular mechanisms of esophageal squamous cell carcinoma (ESCC), our study was designed to use a network-based GBA method to identify the optimal gene functions for ESCC. To identify genomic bio-signatures fo

60. Movilidad residencial de sectores medios y populares: la ciudad de Buenos Aires como punto de llegada
Abstract The article reconstructs residential mobility patterns of individuals and households from popular and middle-class sectors residing in two areas of the city of Buenos Aires, configured around dissimilar segregation patterns. Residential mobility is a powerful lens to show how the social class experience is produced and reproduced in modes of dwellin
