1. Two novel Co(II) complexes with two different Schiff bases: inhibiting growth of human skin cancer cells
Using two flexible Schiff bases, H2L1 and H2L2, two new cobalt II (Co(II))-coordination compounds, namely, Py3CoL1 (1) and Py3CoL2 (2) (Py=pyridine, L1=3,5-ClC6H2(O)C=NC6H3(O)-4-NO2, L2=3,5-BrC6H2(O)C=NC6H3(O)-4-NO2) have been synthesized under solvothermal conditions. Single crystal X-ray structural analysis revealed that compounds 1 and 2 are both six-coor

2. A biologia e o discurso sobre a vida: aproximações acerca do conceito de vida em livros didáticos
This work originates from the need to question the aim of Biology: the life. The discourse on life that emanates from Biology but being confounded with the possibility of a concept for life. It occurs, that to understand ―what kind of life is that of Biology?‖, it is necessary to understand the organization movement of Biological Science and thei

4. Modelagem em geometria digital aprimorada por técnicas adaptativas de segmentos de retas. / Digital geometry modelling enhancement by straight line segment adaptive techniques.
For the representation of digital straight lines, digitized straight line segments and arcs, each of the available research approaches has its advantages and suitable applications. However, taking into account the complexities of real-world scenarios, the use of these representations is not so popular in situations that require flexible models or involving s

5. MONITORING FLEXIBLE RISERS WITH OPTICAL FIBER SENSORS / MONITORAMENTO DE RISERS FLEXÍVEIS COM SENSORES A FIBRA ÓPTICA
The interest in structural health monitoring of flexible risers has grown significantly in recent years. For ducts that are already reaching their design life, monitoring systems can provide early warnings of potential failures and also assist the operator in scheduling downtime. Different techniques are being tested by operators of flexible pipes such as au

6. Comparison between numerical and experimental results on the dynamics of floating system coupled with risers. / Confrontação numérico-experimental da dinâmica de sistema flutuante, considerando seu acoplamento com linhas de produção.
This research aims to present analysis and comparisons, intended to make part of the constant improvement of the oil platform analysis software, called Numerical Offshore Tank (Tanque de Provas Numérico - TPN). For this purpose, small-scale model tests were performed, and the results compared with the numerical model in TPN. The standard unit used in these

7. Modificação do LLDPE através de silanos viabilizando a aplicação em camadas plásticas de linhas flexíveis / Study of silane grafting reactions of low density polyethylene for pipe applications
The flexible lines are flexible structures manufactured through plastic and steel layers that allows its use in order to permit fluid flow in exploration and production of hydrocarbon between offshore oil units and sea bed and/or coast. Nowadays these pipes are one of the main ways to permit the exploration of hydrocarbon in deepwater. The present study aims

8. Structural analysis of bending stiffeners with complex geometries utilized in offshore operations. / Análise estrutural de enrijecedores à flexão de geometria complexa utilizados em operações offshore.
The bending stiffeners discussed in this work are ancillary structural components installed on flexible lines at their connections with floating units in offshore oil production systems. The configuration of these accessories must provide the installation with a gradual variation of the bending stiffness near the lines attaching point, smoothing the curvatur

10. House for others houses: sociogeographic trajectories of domestics workers resident in Aparecida of Goiânia and workers in Goiânia / De casa para outras casas: trajetórias socioespaciais de trabalhadoras domésticas residentes em Aparecida de Goiânia e trabalhadoras em Goiânia
The origin of female domestic labor in Brazil is linked to the slavery period, in this way; it is marked by racial bias. Despite the remote origin, domestic workers as workers remain stigmatized marginally included in society and the world of work. Negative social representations relating to the origin and nature of the occupation (work servile, degrading, n

11. O problema dinâmico de re-configuração de linhas de montagem
This work investigates a version of the assembly line balancing problem in witch the variations on demand levels makes its re-configuration desirable. It reflects aspects related with changing the structure and the operation patterns of the assembly lines. We consider the costs due to tasks reallocation, station activation and a wage tax at each active stati
