This paper introduces the project EFFE that applies and develops a methodology for data collection primarily intended for the study of the correlation between oral and written production in European Portuguese, and that also aims to serve a broad range of studies in different areas. It comprehends (i) a brief review of two scientific contexts occupied with learning to read and write, which are at the basis of the methodological planning of future corpora ; (ii) the methodology adopted for the co...

Maria Ivette Gomes was born July 21, 1948 in Almada, Portugal. After obtaining a BSc in Pure Mathematics in 1970 from the University of Lisbon, Ivette moved in to the University of Sheffield where she completed her PhD in Statistics in 1978, under the supervision of Clive Anderson. Research on statistics of extremes in Portugal has now a long tradition, with Ivette being one of the founders of the movement, along with Tiago de Oliveira (1928–1992). Ivette was co-founder of the Portuguese Statist...

Neste artigo, apresentamos o funcionamento de um novo corpus de escrita e fala de criancas (Portugues LM) nos primeiros anos da escolaridade: a EFFE-On. O seu conteudo esta disponivel online para pesquisas, dirigindo-se, principalmente, a professores, linguistas e terapeutas da fala. A EFFE-On foi desenvolvida no âmbito do projeto Escreves como Falas - Falas como Escreves? no Centro de Linguistica da Universidade de Lisboa (CLUL). Entre outras aplicacoes, o corpus permite identificar formas orto...

Several maize field experiments, including deficit and full irrigation, were used to assess irrigation impacts on yields. The SIMDualKc water balance model was first calibrated and validated to obtain the basal crop coefficients (Kcb) and the depletion fractions for no stress (p) relative to all crop growth stages. The values 0.15, 1.15, 0.30 were obtained for, respectively, the Kcb ini, Kcb mid and Kcb end, as well as p=0.50. The SIMDualKc model provided the partitioning of crop ET into transpi...

Abstract Several maize field experiments, including deficit and full irrigation, were performed in Ribatejo region, Portugal and were used to assess water stress impacts on yields using the AquaCrop model. The model was assessed after its parameterization using field observations relative to leaf area index (LAI), crop evapotranspiration, soil water content, biomass and final yield data and also using default parameters. LAI data were used to calibrate the canopy cover (CC) curve. Results showed...

This study aims to assess the economic feasibility of full and deficit irrigated maize using center pivot, set sprinkler systems and drip tape systems through multicriteria analysis. Different irrigation treatments were evaluated and compared in terms of beneficial water use and physical and economical water productivity for two commodity prices and three irrigation systems scenarios applied to a medium and a large field of 5 and 32ha respectively. Results show that deficit treatments may lead t...

Abstract This paper is the second of a two-part series, with the first part describing the SIMDualKc model, an irrigation scheduling simulation tool that employs the dual crop coefficient approach for calculating daily crop ET and then performs a water balance for a cropped soil. The model was applied, calibrated and validated for rainfed and basin irrigated maize (Coruche, Portugal), rainfed and surface irrigated wheat (Aleppo, Syria), and furrow irrigated cotton (Fergana, Central Asia). Result...
