1. Preparation of Poly(3-hydroxybutyrate-b-ε-caprolactone) by Reactive Extrusion and Production of Electrospun Fibrous Mats
Poly(3-hydroxybutyrate) (PHB) has been proposed to be a potential candidate to be used as biomaterial. However, its poor processability, high brittleness and rigidity have limited its applicability. Transesterification reactions with poly(ε-caprolactone) (PCL), one of the most promising biomedical materials, emerge as an attractive alternative to improve it

2. A PROPOSAL FOR MODELING AND IMPLEMENTING AN INTEGRATED SYSTEM FOR BRAZILIAN CADASTRES ACCORDING TO ISO 19152:2012 LAND ADMINISTRATION DOMAIN MODEL
Abstract: This article proposes the modelling and implementation of an integrated system for Brazilian cadastres, based on the standardized model of land administration described in the ISO 19152:2012 LADM. The model was developed from the identification of the essential elements of the urban, the National Rural Cadastre System and the cadastres of public as

3. Uncertainty estimation in hydrodynamic modeling using Bayesian techniques
RESUMO A avaliação de incertezas tem emergido como estudo primordial para se conhecerem os efeitos dos erros inerentes aos processos de modelagem de perfis de escoamento de vazões de cheia, de natureza aleatória e epistêmica, presentes em dados de entrada como vazões e topobatimetria, na estrutura e parametrização dos modelos matemáticos utilizados

5. Professionalizing bureaucracy and building state capacities: are there unequal advances in Brazilian public administration?
Resumo Este artigo contribui para a discussão sobre a administração pública no Brasil examinando as diferenças entre as quatro funções estatais — funções básicas, bem-estar, infraestrutura e desenvolvimento e funções emergentes — com base nos cargos e nas carreiras dos servidores públicos. Os dados foram coletados em 2014, por meio de pesqui

6. Uberização do trabalho: um fenômeno de tipo novo entre os docentes de São Paulo, Brasil?
Resumo: O presente ensaio visa a problematizar e discutir em que medida a uberização do trabalho se caracteriza, de fato, como um fenômeno de tipo novo. O estudo apoia-se em pesquisas qualitativas e em análise documental referentes às formas de contratação entre 1999 e 2017. Procede-se, para tal análise, à construção do processo histórico das pr�

7. Tensile Armor Wires Submitted to Slow Strain Rate Tests in a Corrosive Environment and Cathodic Protection: a Comparison Between Two Different Microstructures
Tensile armor in flexible pipes consists of two or more layers of steel wires. Damage to the outer sheath may cause ingress of seawater in the annular space and thus corrosion of the armor wires. This work focused on the susceptibility of these wires to stress corrosion cracking (SCC) and hydrogen embrittlement (HE) using a slow strain rate test (SSRT) under

8. Los ejes centrales de la división de poderes en el Estado Constitucional de Derecho
Abstract This paper aims to describe the transformation experienced by the concept of division of powers since it was conceived in the work of Montesquieu to its central pillars in the new paradigm of democratic constitutional rule of law. In this context, I understand that the new paradigm assigns a dual purpose to the principle of separation of powers and

9. Effect of RAP content on flexural behavior and fracture toughness of flexible pavement
Abstract The use of recycled Reclaimed Asphalt Pavement (RAP) material into flexible pavement contributes to sustainable development with environmental and economic benefits. In the present work, Semi-Circular Bending (SCB) specimen has been adopted to study the flexural strength and mode-I fracture toughness of flexible pavement with and without RAP. Two di

10. Influencia de la temperatura en ensayos de arrancamiento sobre diferentes sistemas epoxi-acero de uso en conectores de ductos flexibles
ABSTRACT In the offshore oil fields located in deep and ultra-deep waters they are used flexible pipes. In many cases inside these pipes, the hydrocarbons are transported at elevated temperatures. At the ends of the flexible pipes are installed end fittings, these are the connection with sea platforms and different subsea systems. In the assembly of end fitt

11. The dispersion curve applied in guided wave propagation in prismatic rods.
Abstract The early detection of failures in structures is a subject of great interest in engineering; several of these techniques are linked with the elastic wave propagation, using guided waves is one of these alternatives. Several structures of interest in engineering are laminar arrangements; the wave propagation in this type of structures depends not on

12. Study on the Mixed-Mode HPLC Separation of Shuang-Huang-Lian and Xue-Bi-Jing Injections Based on an Ionic Liquid Column
Both Shuang-Huang-Lian and Xue-Bi-Jing injections are clinically proven efficient and low cost medicines. However, the studies of their chromatographic separation are limited. In this study, a column based on ionic liquid stationary phase was applied for the first time for the analysis of these two injections. For Shuang-Huang-Lian injection, U-shaped plots
