Energy efficiency in agriculture
Baptista, Fatima; Silva, LL; de Visser, C; Gołaszewski, J; Meyer-Aurich, A; Briassoulis, D; Mikkola, H; Murcho, DOne of the EU headline target indicators for Europe is “20% increase in energy efficiency” by 2020. It is anticipated that in the following decades energy use will increase significantly and will have a widespread impact on the economy, including the agricultural sector. Energy use reduction can be achieved by reduced energy input. Improved energy efficiency, however, is only achieved, if energy input per unit ...
Men Older than 50 Yrs Are More Likely to Fall than Women Under Similar Conditio...
Pereira, Catarina L. N.; Baptista, Fátima; Infante, PauloObjective: The aim of this study was to analyze the contribution of sex to the occurrence of falls, accounting for comorbidities and differences in physical fitness. Design: This was a cross-sectional study of 587 community-dwelling adults who were older than 50 yrs. Falls, comorbidities (number of diseases and physical impairments), and physical fitness (body composition, lower and upper body strength and fle...
A Business Intelligence Approach to Support a Greenhouse Tomato Crop Grey Mould...
Neto, Miguel; Baptista, Fátima; Navas, L.M.; Ruiz, G.This paper presents a Business Intelligence architecture proposal, including data sources, data warehouse, business analytics, and information delivery, to launch an early warning system for greenhouse tomato crop grey mould disease. Tomato is a very important crop in the Mediterranean region in general and in Portugal in particular being the production for fresh consumption made essentially in greenhouses. Bot...
Prevalence of Overweight, Obesity, and Abdominal Obesity in a Representative Sa...
Sardinha, Luís; Santos, Diana; Silva, Analiza; Coelho-e-Silva, Manuel; Raimundo, Armando; Moreira, Helena; Santos, Rute; Vale, Susana; Baptista, FátimaThis study determined the prevalence of overweight, obesity, and abdominal obesity in the Portuguese adults and examined the relationship between above mentioned prevalences and educational level. Body mass, stature, and waist circumference were measured in a representative sample of the Portuguese population aged 18–103 years (n = 9,447; 18–64 years: n = 6,908; $65 years: n = 2,539). Overweight and obesity cor...

Stakeholder and driver analysis on energy efficiency in Agriculture. Country Re...
Baptista, Fátima; Silva, Luis L.; Marques, CarlosUntil recently energy efficiency in agriculture has received little attention. Nevertheless, energy consumption in agriculture is considerable, especially when indirect energy use is taken into account. AGREE has the objective of showing the potential of short term energy efficiency gains and the promise of a long term potential. Environmental effects of savings on direct and indirect energy use in agriculture ...
Improving Greenhouse Heating in Portugal
Meneses, J.F.; Baptista, FátimaAlthough several new solutions for greenhouse heating and environmental control are being investigated all over the world; to reduce energy consumption and environmental impacts, to increase the efficiency of energy use for plant production in protected cultivation or to take advantage of the new renewable energy sources, in Portugal the great majority of producers still rely on more conventional heating system...
Development of a Warning System for Controlling Botrytis cinerea in Unheated To...
Baptista, Fátima J.; Bailey, B.J.; Meneses, J.F.Botrytis cinerea is the causal agent of grey mould disease which is one of the most important diseases affecting tomato crops in unheated greenhouses. As a prophylactic measure growers usually apply large quantities of chemical fungicides for its control. Nocturnal ventilation is an effective way to reduce high relative humidity inside greenhouses and can be a useful tool to minimise chemical use in unheated gr...
CONSUMO DE ENERGIA E CUSTOS DE AQUECIMENTO NA PRODUÇÃO DE FLORES E LEGUMES EM E...
Meneses, Jorge F.; Baptista, Fátima J.Pretende-se determinar os consumos de energia e os custos em aquecimento, na produção de flores e de vegetais, ao longo do ano, em estufas de plástico aquecidas, localizadas em diversas zonas de produção de culturas forçadas. No primeiro ano considerou-se Portugal e a produção de rosa. Foram calculados os consumos energéticos e os custos de aquecimento com gasóleo ou gás natural, para duas combinações de temper...
