No. of bitstreams: 0 Previous issue date: 2017-09-01Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Compound optimum design criteria which allow pure error degrees of freedom may produce designs that break down when even a single run is missing, if the number of experimental units is small. The inclusion, in the compound criteria, of a measure of leverage uniformity is proposed in order to produce designs that are more robust to missing observations. By appropriately choosing the weights of each part of the criterion, robust designs are obtained that are also highly efficient in terms of other properties. Applications to various experimental setups show the advantages of the new methods. (C) 2016 Elsevier B.V.

Schiff bases: A short review of their antimicrobial activities

AbstractSchiff bases are aldehyde- or ketone-like compounds in which the carbonyl group is replaced by an imine or azomethine group. They are widely used for industrial purposes and also exhibit a broad range of biological activities. This short review compiles examples of the most promising antimalarial, antibacterial, antifungal, and antiviral Schiff bases. An overview of synthetic methodologies used for the preparation of Schiff bases is also described

Identidade feminina no espaço multicultural: a voz narrativa de Tereza Albues

In a time and space in which identities are no longer fixed, feminine identities are represented in a strategic way, forming the image of contemporary woman who wants to free themselves from male oppression. Tereza Albues’ narrative represents how female identity has been affirmed and self-represented in multicultural space.Em um tempo e espaço em que as identidades não são mais fixas, as identidades femininas são representadas de modo estratégico, formando a imagem da mulher contemporânea que pretende libertar-se do jugo masculino. A narrativa de Tereza Albues representa como a identidade feminina tem se firmado e se autorrepresentado no espaço multicultural

Phosphoric acid increases the porosity and extends the contact area of dental osseo integrated implants.

The surface treatments are performed in dental implants in order to increase the chemical and mechanical connection between the implant and bone, favoring the stability of implant-supported prostheses. The aim of this study was to characterize dental implant surfaces treated with 37% phosphoric acid. Implant surfaces were evaluated divided into groups of fifty samples being distributed in: porcelain samples without treatment; metal samples without treatment; porcelain samples with treatment with 37% phosphoric acid for 30 seconds; metal samples treatment with phosphoric acid at 37% for 30 seconds; porcelain samples with treatment with 37% phosphoric acid for 60 seconds; metal samples with treatment with 37% phosphoric acid for 60 seconds. The samples were characterized by Scanning Electron Microscopy. After the phosphoric acid treatment porosity changes were observed and expanding the contact area. The results show benefits of using phosphoric acid, as a surface with increased roughness; this is desired to occur matrix deposition and growth of bone tissue and facilitates the fixation of implant-supported prostheses

La adhesión de las enfermeras al Método Canguro: subvención para la administración del cuidado de enfermería

;;OBJETIVO:;; construir um modelo teórico explicativo acerca da adesão das enfermeiras ao Método Canguru na Unidade de Terapia Intensiva Neonatal, a partir dos significados e interações para a gerência do cuidado.;;;;MÉTODO:;; pesquisa qualitativa, guiada pelo referencial da Grounded Theory. Foram entrevistadas oito enfermeiras de uma Unidade de Terapia Intensiva Neonatal da cidade do Rio de Janeiro. A análise comparativa dos dados percorreu as etapas de codificação aberta, axial e seletiva, sendo construído um modelo teórico do tipo condicional-causal.;;;;RESULTADOS:;; emergiram quatro categorias principais que compuseram o paradigma de análise: Vestindo a camisa do Método Canguru; Trabalhando com a complexidade do Método Canguru; Encontrando (des)motivação para aplicar o Método Canguru; e Deparando-se com os desafios para a adesão e aplicação do Método Canguru.;;;;CONCLUSÕES:;; o fenômeno central revelou que cada enfermeira e profissional da equipe possui um papel de multiplicador de valores e práticas que podem ou não ser construtivas, influenciando potencialmente na (des)continuidade do Método Canguru na Unidade de Terapia Intensiva Neonatal. Os achados podem ser utilizados para o delineamento de estratégias gerenciais que ultrapassem os cursos e treinamentos e garantam o fortalecimento do modelo assistencial.;;;;OBJECTIVE:;; construct an explanatory theoretical model about nurses' adherence to the Kangaroo Care Method at the Neonatal Intensive Care Unit, based on the meanings and interactions for care management.;;;;METHOD:;; qualitative research, based on the reference framework of the Grounded Theory. Eight nurses were interviewed at a Neonatal Intensive Care Unit in the city of Rio de Janeiro. The comparative analysis of the data comprised the phases of open, axial and selective coding. A theoretical conditional-causal model was constructed.;;;;RESULTS:;; four main categories emerged that composed the analytic paradigm: Giving one's best to the Kangaroo Method; Working with the complexity of the Kangaroo Method; Finding (de)motivation to apply the Kangaroo Method; and Facing the challenges for the adherence to and application of the Kangaroo Method.;;;;CONCLUSIONS:;; the central phenomenon revealed that each nurse and team professional has a role of multiplying values and practices that may or may not be constructive, potentially influencing the (dis)continuity of the Kangaroo Method at the Neonatal Intensive Care Unit. The findings can be used to outline management strategies that go beyond the courses and training and guarantee the strengthening of the care model.;;;;OBJETIVO:;; construir un modelo teórico explicativo acerca de la adhesión de las enfermeras al Método Canguro en la Unidad de Terapia Intensiva Neonatal, a partir de los significados e interacciones para la administración del cuidado.;;;;MÉTODO:;; investigación cualitativa, guiada por el referencial de la Grounded Theory.

Causes for the discards of corneas collected by the ocular tissues bank from Rio Grande do Norte

Objetivo: Identificar as causas dos descartes de córneas no banco de tecidos oculares do Rio Grande do Norte. Métodos: Estudo exploratório descritivo, com dados retrospectivos e abordagem quantitativa, realizado no banco de tecidos oculares do Rio Grande do Norte. As informações foram coletadas por meio de instrumento contendo: número de córneas preservadas, transplantadas e descartadas; causas dos descartes. Resultados: Das 548 córneas captadas, 78,1% foram preservadas e 21,9% descartadas. As causas prevalentes dos descartes foram: infiltrado estromal, sorologia positiva e validade inspirada. Conclusão: Os profissionais da saúde devem diminuir a perda de córneas por motivos evitáveis. Descritores: Transplante de córnea; doadores de tecidos; preservação de tecido
