| A temperatura do ar é um elemento climático de interesse para diversos estudos relacionados à produção agrícola. A partir de dados de temperatura do ar de Botucatu, SP, e Petrolina, PE (diferentes classificações climáticas), medidos entre janeiro de 2004 e dezembro de 2005, foram selecionados dados pontuais com intervalos de seis horas entre cada observação para cada dia. Desta forma, foram analisados três conjuntos de dados, variando a hora do primeiro registro, utilizando a técnica de geoestatística com o intuito de verificar e quantificar o grau de dependência temporal entre as observações. Comprovada a dependência temporal, o método da krigagem ordinária foi utilizado a fim de modelar a variação da temperatura do ar com o intervalo de uma hora. A... |

| ABSTRACT The aim of this study was to characterize the thermal environment in the selection and packing areas of a packing house and its effects on the quality of table grapes produced in the São Francisco Valley, Brazil. The thermal environment was monitored during the winter and summer seasons. The highest value of air temperature (Tair) and the lowest relative humidity (RH) observed in the packing house were 35 °C and 40.0%, respectively, obtained during the summer, for 8 h. After observing the thermal environment data of the packing house, simulations were performed to evaluate the effect of the ideal environmental storage conditions and observed thermal conditions on the postharvest quality of “Thompson” grapes. Grapes were harvested and stored... |

| ABSTRACT The purpose of this study was to evaluate the spatial variation of temperature, relative humidity and black globe humidity temperature (BGHT) index in growing-finishing swine facilities, with and without evaporative air cooler. The experiment was conducted in a 60 x 9 m facility containing 32 pens of 3.20 x 4.00 m each, divided into two sectors. The treatments were without evaporative air cooler (control) and with evaporative air cooler. Temperature and relative humidity data were collected weekly in two periods (morning and afternoon) at 32 different sampling points, encompassing the center of each pen and the outer perimeter of the facility. Animal performance variables were: feed intake, feed conversion, weight out of the nursery, slaughter... |
