1. DIFFERENT RESPONSE TO EXPOSURE TO AIR POLLUTANTS IN GIRLS AND BOYS
RESUMO Objetivo: Identificar associação entre exposição ao material particulado fino e internações por doenças respiratórias em crianças de até dez anos de idade, no município de Cuiabá, MT, estratificando a análise por sexo e calculando excesso de custos. Métodos: Estudo ecológico de séries temporais, sendo a variável dependente o núme

2. Fuzzy logic and hospital admission due to respiratory diseases using estimated values by mathematical model
Resumo Internações por doenças respiratórias geram custos financeiros para o Sistema de Saúde além de custos sociais. O objetivo deste estudo foi elaborar e validar um modelo linguístico “fuzzy” para previsão do número de internações por doenças respiratórias. Foi construído um modelo “fuzzy” para predição de internações por pneumon

3. Effects of exposure to fine particulate matter in elderly hospitalizations due to respiratory diseases in the South of the Brazilian Amazon
Exposure to air pollution is an important cause of hospital admissions due to respiratory diseases. Nevertheless, few studies use pollutant concentration data estimated by mathematical models. A time-series ecological study was developed, using data from hospitalizations due to respiratory diseases in people over 60 years of age, residents of Cuiabá, Brazil

4. Coarse particles and hospital admissions due to respiratory diseases in children. An ecological time series study
ABSTRACT BACKGROUND: Exposure to particulate matter (PM) is associated with hospitalizations due to respiratory diseases among children. DESIGN AND SETTING: An ecological time series study was carried out to identify the role of coarse fractions of particulate matter (PM10-2.5) in hospitalizations among children up to 10 years of age, in Piracicaba (SP)

5. Association between NOx exposure and deaths caused by respiratory diseases in a medium-sized Brazilian city
Exposure to nitrogen oxides (NOx) emitted by burning fossil fuels has been associated with respiratory diseases. We aimed to estimate the effects of NOx exposure on mortality owing to respiratory diseases in residents of Taubaté, São Paulo, Brazil, of all ages and both sexes. This time-series ecological study from August 1, 2011 to July 31, 2012 used infor

6. Estimating the average length of hospitalization due to pneumonia: a fuzzy approach
Exposure to air pollutants is associated with hospitalizations due to pneumonia in children. We hypothesized the length of hospitalization due to pneumonia may be dependent on air pollutant concentrations. Therefore, we built a computational model using fuzzy logic tools to predict the mean time of hospitalization due to pneumonia in children living in São

7. Air pollution and cardiovascular hospital admissions in a medium-sized city in São Paulo State, Brazil
The objective of the present study was to estimate the contribution of environmental pollutants to hospital admissions for cardiovascular disease. A time series ecological study was conducted on subjects aged over 60 years and living in São José dos Campos, Brazil, with a population near 700,000 inhabitants. Hospital admission data of public health patient

8. Idade e crescimento da tartaruga-cabeçuda (Caretta caretta) no litoral sul do Rio Grande do Sul / Age and growth of loggerhead sea turtle (Caretta caretta) in Southern Brazil
The juvenile and sub-adult stages of loggerhead sea turtles (Caretta caretta) are poorly studied in Brazil. We present age estimates and a growth model for loggerhead sea turtles in the South Atlantic Ocean obtained through skeletochronological analysis of humeri obtained from both neritic and oceanic stage individuals. Since it was validated that each incre

9. Análise e previsão dos recolhimentos compulsórios sobre recursos à vista / Analysis and Forecast of Reserve Requirements
This dissertation discusses the reserves requirements in Brazil. It analyses and forecasts the top five time series that form these requirements. A VARMAX model with autoregressives lags, moving averages and exogenous variables is used. The interest rate Selic, exchange rate BRL/USD, commerce sales, consumption and income are the exogenous variables. A BEKK

10. Validation of heat fluxes over the tropical atlantic: CPTEC coupled ocean-atmosphere model and observations / Validação dos fluxos de calor sobre o atlântico tropical: modelo acoplado oceano-atmosfera do CPTEC e observações
The goal of this work is to infer the importance of surface heat fluxes, estimated by several methods, in the determination of the Sea Surface Temperature (SST) fields in the tropical Atlantic using a set of general circulation ocean model Modular Ocean Model 3 (MOM 3) simulations and a Centro de Previsão de Tempo e Estudos Climáticos (CPTEC) coupled ocean

11. REACTIVE POWER FORECASTING / PREVISÃO DE POTÊNCIA REATIVA
No novo modelo do Setor Elétrico é essencial desenvolver novas técnicas que estimem valores futuros, a curto e longo-prazos, das potências ativa e reativa. Com base nisso, este trabalho tem por objetivo apresentar uma nova técnica de previsão horária de potência reativa a curto-prazo, por subestação, baseada na linearidade existente entre as potên

12. A relação entre os preços de açúcar nos mercados doméstico e internacional. / Sugar price relation between international and brazils markets.
With more than a half of its production exported and about 30% of market share in the world sugar market, nowadays Brazil is the worlds leading exporter of sugar. So, its expected that the sugar physical prices in the State of São Paulo (CEPEA), Brazil´s leading production region, have any sort of relation with the international prices of this commodit
