1. Cost-utility of quadrivalent versus trivalent influenza vaccine in Brazil – comparison of outcomes from different static model types
ABSTRACT Background: Influenza burden in Brazil is considerable with 4.2–6.4 million cases in 2008 and influenza-like-illness responsible for 16.9% of hospitalizations. Cost-effectiveness of influenza vaccination may be assessed by different types of models, with limitations due to data availability, assumptions, and modelling approach. Objective: To und

2. The Prediction of the Man-Hour in Aircraft Assembly Based on Support Vector Machine Particle Swarm Optimization
ABSTRACT: As the representative of manufacturing industry, aircraft assembly lacks of effective method to forecast man-hour. The forecasting accuracy of existing methods is universally pretty low. On the basis of full analysis of aircraft assembly's feature, this study proposes a forecasting model based on support vector machine (SVM), which is optimized by

3. Aprendizado não supervisionado de hierarquias de tópicos a partir de coleções textuais dinâmicas / Unsupervised learning of topic hierarchies from dynamic text collections
The need to extract new and useful knowledge from large textual collections has motivated researchs on Text Mining methods. Among the existing methods, initiatives for the knowledge organization by topic hierarchies are very popular. In the topic hierarchies, the knowledge is represented by topics and subtopics, and each topic contains documents of similar c

4. Granlog : um modelo para analise automatica de granulosidade na programacao em logica / Granlog a model for automatic granulariy analysis in logic programming
A exploração do paralelismo na programação em lógica e considerada uma alternativa para simplificação da programação de maquinas paralelas e para aumento do desempenho de programas em lógica. Desta forma, a integração da programação em lógica e sistemas paralelos tornou-se nos últimos anos um centro de atenções da comunidade ciêntifica. De

5. Processamento, caracterização e estudo de fenômenos críticos do sistema supercondutor (Y - Er)Ba2Cu3O7
The effect of Er substitution on the mechanical properties of ab and a(b)c planes of melt-textured Y Ba2Cu3O7 is reported in the present work. The samples were characterized by scanning electron microscopy, X-ray diffraction, resistivity measurements and mechanical properties by instrumented indentation and conventional Vickers measurement. The X-ray pattern

6. Performance analysis of IP traffic grooming over WDM networks with variable granularity flows. / Análise de desempenho da agregação de tráfego IP em redes WDM com variação da granularidade dos fluxos.
The present work covers the IP traffic grooming strategies in optical WDM networks. Using an entire wavelength to transport an individual traffic flow in a WDM network is inefficient. The problem known as traffic grooming consists in the multiplexing of different traffic flows in a single wavelength within a lightpath. The allocation of multiple traffic flow

7. Integração da ferramenta de teste POKE-TOOL em ambientes de engenharia de software
A great number of CASE tools is reaching the market. These tools are usually designed to work isolatedly, in which case they do not support all the phases of the software process. Open software engineering environments provide such facilities that tools can be used in an integrated and cooperative way. In order to integrate a tool into an open software engin

8. Estrogen receptor β regulates epithelial cellular differentiation in the mouse ventral prostate
We have previously reported epithelial cellular hyperplasia in ventral prostates (VP) of mice lacking estrogen receptor β (ERβ). To investigate the causes of this phenomenon, we measured cellular proliferation and apoptosis in VP of ERβ-/- and WT mice. With BrdUrd labeling, the number of proliferating cells was 3.6-fold higher in ERβ-/- mice. There was a

9. Schwann cells proliferate but fail to differentiate in defined medium.
Primary cultures of dorsal root ganglia cells from 18- to 21-day rodent embryos were studied for their ability to express Schwann cell function in a defined medium lacking serum and embryo extract. It was confirmed that Schwann cells, but not fibroblasts, are able to proliferate in response to contact with axons when cultured in this defined medium. We here

10. Isolation of viable Hodgkin and Reed-Sternberg cells from Hodgkin disease tissues
Hodgkin disease (HD) is characterized by a small number of malignant Hodgkin and Reed-Sternberg (H/RS) cells among a major population of nonmalignant cells. The analysis of H/RS cells has been hampered by their low frequency and fragility. Here, we describe the isolation of viable H/RS cells from HD affected tissues by high gradient magnetic cell sorting (MA
