61. Lung disease detection using feature extraction and extreme learning machine
INTRODUCTION: The World Health Organization estimates that by 2030 the Chronic Obstructive Pulmonary Disease (COPD) will be the third leading cause of death worldwide. Computerized Tomography (CT) images of lungs comprise a number of structures that are relevant for pulmonary disease diagnosis and analysis. METHODS: In this paper, we employ the Adaptive Cris

63. In vitro biomineralization of a novel hydroxyapatite/superhydrophilic multiwalled carbon nanotube nanocomposite using simulated body fluids
Nanobiomaterials based on superhydrophilic vertically-aligned multi-walled carbon nanotubes (VAMWCNT-O2) are promising for their properties and bone tissue biocompatibility. VAMWCNT-O2 films with nanohydroxyapatite (nHAp) aim to improve mechanical properties and biocompatibility of this new nanocomposite due to its resemblance to bone matrix structure. This

64. Distributed generators performance during short-circuits considering fault ride-through requirements / Desempenho de geradores distribuídos durante curtos-circuitos considerando requisitos de suportabilidade a afundamentos de tensão = : Distributed generators performance during short-circuits considering fault ride-through requirements
The increase of distributed generation penetration in distribution systems not only helps to diversify the electrical matrix but also brings both technical and economic benefits. Yet, it also raises worries related to energy supply reliability. For wind power plants into the medium and high voltage networks there are the grid codes for "Fault Ride-Through" w

65. Construção de sensores eletroquímicos utilizando como matriz materiais cerâmicos SI O IND. 2 / M IND. X O IND. Y , e materiais cerâmicos eletricamento condutores SI O IND. 2 / C/ M IND. X O IND. Y , preparados pelo processo sol-gel / Construction of electrochemical sensors using ceramic materials SI O IND. 2 / M IND. X O IND. Y and electrically conducting ceramic materials SI O IND. 2 /C/ M IND. X O IND. Y as matrix, prepared for the sol-gel process
This work describes the synthesis and characterization of three different materials: SiO2/SnO2, SiO2/SnO2/Sb2O5 and the film of Nb2O5 formed on the surface of the ceramic material SiO2/C obtained by sol-gel process and to use them as matrix in the development of electrochemical sensors. The mixed oxides, SiO2/SnO2, were synthesized using as source of SnO2, S

66. A MODEL FOR PROJECT SELECTION AND EVALUATION IN A SOCIAL SERVICE ORGANIZATION / MODELO PARA SELEÇÃO E AVALIAÇÃO DE PROJETOS EM UMA ORGANIZAÇÃO DE SERVIÇO SOCIAL
This paper proposes a tool to support decision-makers of social institutions in the process of selection and evaluation of their projects. The proposed model was created out of necessity mapped in the organization¿s strategic planning process, to obtain indicators for evaluating objectives aligned with its mission and vision and with aims of starting a inst

67. AvaliaÃÃo de edidas de influÃncia local em modelos lineares espaciais t-Student / Evaluation of local influence measure in t-student linear spacial models
The system of precision agriculture considers that agricultural areas are not homogeneous, so, fertilizers and agricultural lime must be applied at different rates, according to chemical analyzes and physical properties of soil. The use of geostatistics with precision agriculture allows establishing spatial dependence relations among the sampled points. It i

69. Elementos para uma política de avaliação das ações de saúde mental na atenção primária : contribuições de uma pesquisa qualitativa avaliativa / Elements for an evaluation policy on mental health iniciative in primary care : contribution of a qualitative evaluation research
Inclusion of mental health initiatives in the work of family health teams has an important relevance if we consider epidemiological magnitude of mental health disorders and the need of increasing access for mental health care in the Brazilian Public Health System (SUS). This has been a priority of the Brazilian Mental Health Policy for primary care in the Mi

70. Specificity and selectivity improvement in doping analysis using comprehensive two-dimensional gas chromatography coupled with time-of-flight mass spectrometry
Comprehensive two-dimensional gas chromatography coupled with time-of-flight mass spectrometry was used for the identification of forty doping agents. The improvement in the specificity was remarkable, allowing the resolution of analytes that could not be done by one-dimensional chromatographic systems. The sensitivity observed for different classes of prohi

71. Da antropologia pragmática à antropologia bioética: o princípio da prudência-ponte dirimindo o reducionismo em bioética pertinente à vida humana no nível molecular
This thesis aims to demonstrate that there is a reductionism in bioethics and this comes out as one of three ways: a) topological; b) proximity; and c) life secularization. These three forms of reductionism hinder a definition of a moral status and also a prudential deal of the genetic materials and human embryos. Thus, there is a quickly advance of biotechn
