1. Climate Variability and Avian Cholera Transmission in Guangxi, China
ABSTRACT In recent years, Guangxi has become one of the most severely affected provinces by epidemics of avian cholera in China. To date, the major determinant climatic factors of the disease in the region have remained largely unknown, making it difficult to effectively target countermeasures for avian cholera surveillance and control. This study aimed to q

2. Performance quantification of clustering algorithms for false positive removal in fMRI by ROC curves
Abstract Introduction Functional magnetic resonance imaging (fMRI) is a non-invasive technique that allows the detection of specific cerebral functions in humans based on hemodynamic changes. The contrast changes are about 5%, making visual inspection impossible. Thus, statistic strategies are applied to infer which brain region is engaged in a task. Howeve

3. Investigating cardiolocomotor synchronization during running in trained and untrained males
Introduction This study aims at investigating the coupling of the cardiac and locomotor systems during running in trained and untrained males. Methods Sixteen healthy young males subjects were submitted to an anthropometric evaluation, followed by a treadmill test at 70% to 75% of heart rate reserve. Based on the average velocity, they were divided into two

Aspectos intuitivos, preferências intertemporais e decisões orçamentárias: um estudo quase-experimental envolvendo práticas de alocação de recursos. / Aspectos intuitivos, preferências intertemporais e decisões orçamentárias: um estudo quase-experimental envolvendo práticas de alocação de recursos.
Behavioral biases, such as those generated by asymmetric information, permeate the process of resource allocation to organizational activities, as well as numbers, the budget requires people with cognitive, affective and emotional limitations and therefore subject to being impelled to "errors" in their daily activities. With the aim to identify how the intui

6. The cross-correlation between output and nominal variables in new keynesian models calibrated to Brazil and the U.S.
Este artigo investiga se a interação entre formação de hábito e uma regra de Taylor prospectiva consegue reproduzir o padrão de correlação entre produto e variáveis nominais (inflação e taxa de juros) para o Brasil e os Estados Unidos. O estudo emprega um modelo Novo-Keynesiano com rigidez de preço ou de informação. O padrão de correlações v

7. AnÃlise espacial de uma transeÃÃo de solo agrÃcola cultivado com soja.
The knowledge about soil and plant attributes is important for the improvement of agricultural management. Intense tillage activities may induce not only alterations in the soil attributes but also decrease in productivity. Studies directed to the soil and plant spatial variability identification and the relations amid these variables are tools for agricultu

8. Ontogenia do Padrão Vocal Individual do Peixe-Boi da Amazônia Trichechus inunguis (Sirenia, Trichechidae)
There are evidences that Amazonian manatee convey identity information, to its conspecifics, using sounds. Evidences about the presence of vocal signature and individual recognition have been documented in the specie. However, there is little information about the vocal behavior and the development of the individual vocal pattern for this species. The vocali

9. Measures of the interannual marine variability on southeast Brazilian bight and its relationship to the spawning areas of Brazilian sardine (Sardinella braziliensis) / Medidas da variabilidade interanual marinha sobre a plataforma continental sudeste do Brasil e sua relação com áreas de desova da sardinha-verdadeira (sardinella brasiliensis)
This work aims to investigate the relation of marine interannual variability in a region located in southern coast of Brazil, also known as the Southeast Brazilian Bight (SBB) and the spawning areas of the Brazilian sardine (Sardinella braziliensis) in SBB. SBB marine ecosystems are related to a strong influence of a coastal upwelling system. Variables used

10. Retroanálise probabilista aplicada à análise dinâmica da cravação de estacas. / Probabilistic back-analysis applied to dynamic loading test for pile driving.
An dynamic loading test can be performed in concrete piles, bored piles, drilled shafts, auger cast-in-place (continuous flight auger) piles. Such essay bases on the Theory of the Propagation of Wave in piles with the aim of evaluate the capacity of static load mobilized from the dynamic event. The analysis of the test is made by a PC program (p.e. CAPWAP or
