13. High Temperature Erosion-oxidation Resistance of Thermally Sprayed Nanostructured Cr3C2-25(Ni-20Cr) Coatings
This study reports the high temperature erosion-oxidation (E-O) behavior of conventional and nanostructured Cr3C2-25(Ni-20Cr) coatings prepared by high velocity oxygen fuel (HVOF) spraying. As-received and nanostructured Cr3C2-25(Ni-20Cr) powders with mean crystallite sizes of 145 nm and 50 nm respectively, were used to prepare 120 - 200 µm thick coatings o

14. Where do these bugs come from? Phenotypic structure of Triatoma infestans populations after control interventions in the Argentine Chaco
House re-invasion by native triatomines after insecticide-based control campaigns represents a major threat for Chagas disease vector control. We conducted a longitudinal intervention study in a rural section (Area III, 407 houses) of Pampa del Indio, northeastern Argentina, and used wing geometric morphometry to compare pre-spray and post-spray (re-infestan

15. Cardiac troponin and C-reactive protein for predicting all-cause and cardiovascular mortality in patients with chronic kidney disease: A meta-analysis
Elevated serum levels of cardiac troponin and C-reactive protein are associated with all-cause and cardiovascular mortality in patients with end-stage renal disease. However, the relationship between these two biomarker levels and mortality in patients with chronic kidney disease remains unclear. We conducted a meta-analysis to quantify the association of ca

16. Heterogeneous flow during high-pressure torsion
High-Pressure Torsion (HPT) has attracted significant attention in recent years as an effective technique to process ultrafine and nanostructured materials. The hydrostatic pressure developed during processing prevents the occurrence of cracks and the low thickness to diameter ratio provides the opportunity for developing high strains at low numbers of rotat

17. Simulações de líquidos super-resfriados via dinâmica molecular
This work presents the study of two models of glass-forming liquids using molecular dynamics simulations. The first model aims to analyze the effects on glassy dynamics which allow the enhancement of the glass formability on metallic glass formers. The Pd45Ni55 binary alloy and the Pd35Ni55Pt10 ternary one are modeled via the Embedded Atom method interaction

18. Aplicação de redes neurais artificiais no processo de ajuste de histórico / Application of artificial neural networks in the history matching process
The history matching process is one of the most important stages involving studies of reservoirs, because with the adjusted reservoir model, the production forecasts can be done with higher reliability and different production strategies can be evaluated to obtain greater final recovery associated with less costs. However, this process have several problems

19. Retrieval analysis of different orthodontic brackets: the applicability of electron microprobe techniques for determining material heterogeneities and corrosive potential
OBJECTIVE: The objective of this study was to investigate the applicability of micro-analytical methods with high spatial resolution to the characterization of the composition and corrosion behavior of two bracket systems. MATERIAL AND METHODS: The surfaces of six nickel-free brackets and six nickel-containing brackets were examined for signs of corrosion an

20. Dos \ Essais de Michel de Montaigne\ : tradução e reformulação / Essais de Michel de Montaigne: translation and reformulation
A tradução de Sérgio Milliet dos Essais de Michel de Montaigne para o português brasileiro envolve um trabalho de leitura, interpretação e escritura em várias frentes: estilística, retórica, linguística, antropológica, histórica, etc. O objetivo deste trabalho é identificar como foram traduzidos os pontos de inflexão nos quais os discursos do O

23. Processing and characterization of Ti-Cu-Ni-Zr and Ti-Fe-Co-Zr glass former alloys / Processamento e caracterização de ligas amorfizáveis TiCuNiZr e TiFeCoZr
Searching the development of bulk metallic glasses the research takes two directions, the development of alloys with a high glass forming ability and development of new processes or improving existing processes. In this context, the present study aimed at to evaluate the solidification processes suction and centrifugal casting, both using copper moulds. The

24. The stochastic modeling applied to the maintenance of cultural diversity / A modelagem estocástica aplicada à manutenção da diversidade cultural
The sociocultural stochastic modeling introduced by Robert Axelrod is traditionally referred to as the maintenance of cultural diversity. Since it generates the appearance of heterogeneities on a steady state, even the primordial interaction tends to gauge the interactors. Due to its simplicity, numerous interpretations of this model were studied, as well as
