1. Dendritic Gold Nanoparticles Towards Transparent and Electroactive Electrodes
Abstract: The combination of UV-visible absorption and electrochemical experiments (spectroelectrochemistry) enables to obtain highly specific spectroscopic information (in situ and operando) from modified surfaces. However, such application can be limited by the self-absorbance, for example, when metallic nanoparticles are present on modified surfaces. Indi

4. Fishes of the Amazon: diversity and beyond
Abstract: The Amazon basin houses a particular group of freshwater organisms, whose study tells the geological history of the region, how biological diversity was shaped, how it is maintained, and what it hides. The fish of the Amazon is represented by more than 3,000 known species distributed from the basal groups up to the more specialized ones. This speci

5. Review of the family Rivulidae (Cyprinodontiformes, Aplocheiloidei) and a molecular and morphological phylogeny of the annual fish genus Austrolebias Costa 1998
ABSTRACT The family Rivulidae is the fourth most diverse clade of Neotropical fishes. Together with some genera of the related African family Nothobranchiidae, many rivulids exhibit a characteristic annual life cycle, with diapausing eggs and delayed embryonic development, which allows them to survive in the challenging seasonal ponds that they inhabit. Rivu

6. Fases identificables en la zona de interacción de placas combustibles dispersas U3Si2/Al
ABSTRACT Fuel elements based on U3Si2 particles dispersed in a pure Al matrix (known as dispersion fuel element) are known to be very stable under irradiation, in plate type configurations. For this reason, they were or are being used to convert to low enriched uranium a large number of research reactors without significant loss in performance. According to

7. Informality and employment vulnerability: application in sellers with subsistence work
ABSTRACT OBJECTIVE To describe the origin, evolution, and application of the concept of employment vulnerability in workers who subsist on street sales. METHODS We have carried out an analysis of the literature in database in Spanish, Portuguese, and English, without restriction by country. This is a review of the gray literature of government reports, a

8. Carbon nanotube buckypaper reinforced polymer composites: a review
Abstract This review provides valuable information about the general characteristics, processing conditions and physical properties of carbon nanotube buckypaper (BP) and its polymer composites. Vacuum filtration is the most common technique used for manufacturing BP, since the carbon nanotubes are dispersed in aqueous solution with the aid of surfactant. Pr

9. The role of Brazilian National Health Information Systems in assessing the impact of Zika virus outbreak
Abstract The Zika virus (ZIKV) epidemic has become a public health emergency following its association with severe neurological complications. We aim to discuss how the Brazilian National Health Information Systems can help to assess the impact of the ZIKV epidemic on health outcomes potentially related to ZIKV. Health outcomes potentially related to ZIKV in

11. EXPERIMENTAL STUDY OF ELONGATED BUBBLES IN HORIZONTAL TWO-PHASE INTERMITTENT FLOW / ESTUDO EXPERIMENTAL DE BOLHAS ALONGADAS NO ESCOAMENTO BIFÁSICO HORIZONTAL INTERMITENTE
The present work experimentally studied several relevant dynamic characteristics of gas-liquid intermittent flow through a horizontal pipe. All tests were performed in a test section formed by 50.8 mm internal diameter pipe using air and water as working fluids. The tests covered a region where the flow undergoes a complex transition from elongated bubble fl

12. Um processo de aquisição e mapeamento de dados para as bacias sedimentares marginais brasileiras
Finding oil is a hard task that requires large amounts of information and resources. Along decades of research, geoscientists from Petrobras have accumulated great amout of data. Therefore, in petroleum geology other sources of important data are generally dispersed and have many forms of representation. This Master Thesis reports the creation of a database
