Libro de Actas - X Simposium Hispano Português de Relaciones Hidricas, 2010 ; Deficit irrigation techniques, implying that water is supplied at levels below full crop evapotranspiration throughout the growing season or in specific phenological stages, such as regulated deficit irrigation (RDI) or partial root drying (PRD), emerged as potential strategies to increase water savings with marginal decreases of yie...
Background - A large proportion of vineyards are located in regions with seasonal drought (e.g. Mediterraneantype climates) where soil and atmospheric water deficits, together with high temperatures, exert large constraints on yield and quality. The increasing demand for vineyard irrigation requires an improvement in the efficiency of water use. Deficit irrigation has emerged as a potential strategy to allow c...

Com o objetivo de avaliar a qualidade da fibra do algodoeiro, cv. BRS 201, fertilizado com diferentes doses de uréia, um experimento de campo foi conduzido no município de Barbalha, CE, no ano de 2005. Utilizou-se o delineamento experimental em blocos ao acaso com quatro repetições e seis tratamentos, constituídos por seis doses de uréia (0, 60, 120, 180, 240, -1 300 kg.ha ), aplicadas em datas previamente esta...

The performance of a new VUV photosensor, based on an micro-hole and strip plate (MHSP) electron multiplier with a CsI photocathode deposited on its top electrode, is described. This photosensor presents gains above 104 when operating in an Ar-5%Xe gas mixture at 1 atm. Although the gain of a single MHSP is not sufficient for efficient detection of single photons, this simple UV photosensor may be useful for th...
