Climate Modelling of a Greenhouse with Proportional Environmental Control
Louro, M.; Baptista, F.J.; Mourão, I.Performance of greenhouse environmental control systems can be evaluated by predictive climate models. In this work, a model for the prediction of environmental parameters such as temperature and humidity based on energy and mass balances, was developed and validated for a greenhouse controlled with a proportional environmental control system. The greenhouse is in Viveiros do Furadouro, a forestry nursery from ...
Modelação do clima em estufa climatizada com sistema de controlo proporcional –...
Louro, M.; Baptista, F.J.; Mourão, I.O controlo ambiental em culturas protegidas assume uma grande importância e, a par da rega e da nutrição, é um dos factores limitantes do crescimento e desenvolvimento das plantas. A eficácia deste controlo pode ser avaliada pela utilização de modelos matemáticos para a previsão das condições climáticas interiores, que após a sua validação, permite a simulação para diferentes condições climáticas exteriores e/o...
Designing activated carbons from natural and synthetic raw materials for pollut...
P.A.M. Mourão; I.P.P. Cansado; P.J.M. Carrott; M.M.L. Ribeiro CarrottOver the last decades the literature has shown the possibility of producing activated carbons (AC) from a wide variety of raw materials, and to use them as one of the most environmentfriendly solutions for waste disposal [1]. Simultaneously, it has been shown that the adsorption of pollutants from different sources by activated carbons is one of the most efficient techniques for remediating or solving this kind...
Prevalence of overweight and obesity in 7-9-year-old Portuguese children: Trend...
Padez, C.; Fernandes, T.; Mourão, I.; Moreira, P.; Rosado, V.The aim of this study was to assess the prevalence of overweight and obesity in Portuguese children age 7-9 years and to analyze trends in body mass index (BMI) from 1970-2002. Data were collected from October 2002 to June 2003 in a random sample of Portuguese children. Height and weight were measured and BMI (Kg/m2) was calculated. The International Obesity TaskForce (IOTF) cutoffs to define overweight and obe...
Dietary calcium and body mass in Portuguese children
Moreira, P.; Fernandes, Teresa; Mourão, I.; Padez, C.; Rosado, V.Many epidemiologic studies have identified strong inverse correlations between adiposity and calcium intake, and dietary calcium is now well recognised to play an important role in the prevention and treatment of obesity. The objective of our study was to assess nutritional intake in school children (7 to 9 years old) and relate calcium intake to body mass index (BMI).
Prevalence of Overweight and Obesity in 7-9 Year-Old portuguese Children: Trend...
Padez, C.; Fernandes, Teresa; Mourão, I.; Moreira, P.; Rosado, V.OBJECTIVE: The aim of this study was to analyse changes in the prevalence of overweight and obesity between 1986 and 2000 in Portuguese conscripts, and to examine the role of place of residence and educational level. STUDY DESIGN: Cross-sectional study. METHODS: Data sets from the cross-sectional annual surveys of all 18-year-old Portuguese males born between 1966 and 1981 and examined between 1986 and 2000 (85...
