1. Multivariate adaptive regression splines (MARS) applied to daily reference evapotranspiration modeling with limited weather data
ABSTRACT. Estimation of reference evapotranspiration (ETo) is very relevant for water resource management. The Penman-Monteith (PM) equation was proposed by the Food and Agriculture Organization (FAO) as the standard method for estimation of ETo. However, this method requires various weather data, such as air temperature, wind speed, solar radiation and rela

2. No mullet, no gain: cooperation between dolphins and cast net fishermen in southern Brazil
ABSTRACT We report on the interaction between common bottlenose dolphins, Tursiops truncatus (Montagu, 1821) and cast net fishermen in southern coast of Brazil. The fishery was monitored in the mouth of the Tramandaí River Estuary to investigate the seasonality of catches and their relationships with a set of variables: presence/absence and number of bottle

3. Wind pollination and propagule formation in Rhizophora mangle L. (Rhizophoraceae): resource or pollination limitation?
Rhizophora mangle é uma espécie de mangue considerada como autocompatível e polinizada por vento e insetos. No entanto, não há informações sobre produção de frutos por autogamia ou agamospermia e sobre o comportamento de forrageio de seus visitantes florais. Dessa forma, o presente estudo analisou os sistemas de polinização e reprodução de R. m

4. Foraging strategies of the ant Ectatomma vizottoi (Hymenoptera, Formicidae)
Foraging strategies of the ant Ectatomma vizottoi (Hymenoptera, Formicidae). Foraging activity may be limited by temperature, humidity, radiation, wind, and other abiotic factors, all of which can affect energy costs during foraging. Ectatomma vizottoi's biology has only recently been studied, and no detailed information is available on its foraging patterns

5. Desafios e oportunidades da geração eólica e termelétrica a gás natural no Sistema Elétrico Peruano. / Challenges and opportunities of the wind generation and to natural gas thermal in the Peruvian Electricity System.
Several countries around the world have increasingly sought to diversify their electrical matrix in order to reduce dependence on fossil fuels and reduce emissions of gases responsible for worsening greenhouse effect in the atmosphere. As a result, has grown the participation of some renewable energy sources that until two decades ago did not occupied a prom

6. ANÁLISE E CONTROLE DE GERADOR SÍNCRONO A ÍMÃ PERMANENTE APLICADO A SISTEMA DE CONVERSÃO DE ENERGIA EÓLICA / ANALYSIS AND CONTROL OF PERMANENT MAGNET SYNCHRONOUS GENERATOR APPLIED TO WIND ENERGY CONVERSION SYSTEM
This dissertation addresses the analysis and control of permanent magnet synchronous generators (PMSG) found in wind energy conversion system. The operation modes of the wind turbine the current and voltage constraints of a PWM rectifier are defined and a methodology to determine the generator current is presented. The generator currents obtained guarantee t

7. Study of the atmospheric and oceanic conditions in the southweast atlantic and its relation with the Brazilian sardine catch extremes / Estudo das condições atmosféricas e oceânicas do atlântico sudoeste e suas associações com extremos de captura da sardinha-verdadeira
The Brazilian Sardine is an important fishing resource for the country, with restricted occurrence in the Southeast Brazilian Bight (SBB). Landing records of this species shows years of high capture, as in 1973 with 225 thousand tons and the minimum in 2000 with 20 thousand tons. In this work was studied the oceanic and atmospheric characteristics of the mos

8. Sensibilidade do modelo WASP aos efeitos da estabilidade atmosférica no Nordeste do Brasil. / Sensitivity of the WASP model the effects of atmospheric stability in Northeast Brazil.
O crescente interesse na exploração da energia eólica requer ferramentas confiáveis para estimar os recursos eólicos em uma região. Atualmente, o WAsP (Wind Atlas Analysis and Application Program) é um dos modelos numérico computacional mais utilizado para este cálculo. No entanto, os valores dos parâmetros utilizados neste modelo são representati

9. Desempenho térmico de cobertura verde utilizando a grama Brachiaria humidicola na cidade de São Carlos-SP
This work aims to analyze the thermal behavior of a green roof with the Braquiária grass (Brachiaria humidicola), that reaches 1m height, comparing it with a traditional roof (concrete slab on show). Considering temperature and relative humidity data obtained through field measurements in different months, the thermal performance of the green and traditiona
