2. Evaluation of ocular psoriasis with meibography
Abstract Background: Previous studies has shown that dry eye test abnormalities, meibomian gland dysfunction (MGD), may occur in psoriasis. Objectives: The authors aimed to evaluate the dry eye disease (DED), MGD, in psoriasis patients with meibography which is a current, objective, noninvasive method for patients with meibomian gland diseases, to investig

3. Poder Monetário Estrutural: do padrão ouro ao dólar flexível
Resumo As necessidades de financiamento das guerras no século XVII levaram a Inglaterra a realizar inovações financeiras importantes, que deram lugar à Revolução Financeira. Esse conjunto de mecanismos - dívida pública de longo prazo, banco central e mercados secundários relevantes - permitiram à Grã-Bretanha desempenhar um papel central no sistem

4. Violências e Instituição Maternidade: uma Reflexão Feminista Decolonial
Resumo A sociedade brasileira possui um histórico marcado por violências e autoritarismos. A história colonial que funda a ideia de Brasil se consolida com a noção de identidade nacional baseada em aspectos racistas, sexistas e heteronormativos. Essas violências têm sido denunciadas e visibilizadas a partir de um olhar focado na dimensão pública e m

5. Uma análise do dilema da persistência da inflação de serviços no Brasil
Resumo Este artigo analisa o Dilema da Persistência da Inflação de Serviços no Brasil, para o período entre agosto de 1999 e fevereiro de 2017. Para efeitos de comparação, cálculos também são feitos para o IPCA, para a inflação desagregada de bens, além de alguns itens desagregados da própria cesta de serviços. São utilizados modelos ARFIMA,

6. Development and characterization of active film with omega-3 as a proposal for enrichment of butter
Abstract Active food packaging aims to interact with food in order to improve nutritional, sensory, physicochemical or microbiological properties of the food products. The aim of this work was to development and characterization of active film with omega-3 and flavored with oregano essential oil for butter. It was produced three films: control (T1), active

7. Caracterización de resinas epoxi para uso en conectores de ductos flexibles
ABSTRACT In the offshore productions of gas and oil are frequently used flexible pipes. The end fitting is the connection between the flexible pipe body and the production unit, at the assembly of this component is used epoxy resin to fill the free space inside it. This polymeric material holds the tensile armor wires to form the anchoring system. A critical

8. Structural and mechanical properties of a giomer-based bulk fill restorative in different curing conditions
ABSTRACT Objective: The main goal of this study was to compare the polymerization degree of bulk-fill giomer resin cured with three different light-curing units (LCUs): a polywave third-generation (Valo); a monowave (DemiUltra: DU); and a second-generation LED (Optima 10: Opt) LCUs by using structural and mechanical properties. Material and methods: Giomer

9. Influence of microcrystalline cellulose in thermoplastic starch/polyester blown films
Abstract This work investigated the influence of microcrystalline cellulose (MCC) in thermoplastic starch/poly (butylene adipate-co-terephthalate) films produced by blown extrusion, using different MCC contents (4, 7 and 10 g.100 g-1). The films were characterised for their mechanical, structural and barrier properties. Increasing fibres concentration reduce

10. Nanocomposites films obtained from protein isolates of mechanically deboned chicken meat added with montmorillonite
Abstract The aim of this study was to evaluate the properties of nanocomposite films of protein isolates from mechanically deboned chicken meat with organoclay (montmorillonite). For the film development, a 23 experimental design was performed with three levels, protein isolate (2, 3.5, 5 g.100 mL-1 of solution), montmorillonite (0.3, 0.5, 0.7 g.100mL-1 of s

11. 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

12. Evaluating the existence of structural change in the brazilian term structure of interest : evidence based on cointegration models with structural break
This paper investigates whether there is evidence of structural change in the Brazilian term structure of interest rates. Multivariate cointegration techniques are used to verify this evidence. Two econometrics models are estimated. The rst one is a Vector Autoregressive Model with Error Correction Mechanism (VECM) with smooth transition in the deterministi
