    Notes: In an increasing competitive market where offer exceeds demand, developing customervalue is nowadays a key driver of industrial activities. Reducing costs, increasing quality, deliver ontime and the introduction of the right product quickly are unavoidable elements to succeed. A higherproduct variety for mass production and short lead-time are main features of mass customization.Flexibility arises as a productive and competitive factor to face it, of particular interest in assemblysystems, which allow the postponement of final variety, integrating all former tasks of the supplychain. In this scenario, flexibility helps to face uncertainty in decision-making, while the increase ofsystem complexity requires extra control and management efforts. Both flexibility and complexityare briefly reviewed. Next, it is introduced a joint analysis of flexibility and complexity useful fordecision-making. Both are linked to the uncertainty of the possible states of the system and aquantitative approach of general application is presented. Finally, based on a model simulation, afirst case application illustrates product variety increase in an assembly system and some decisionmakingtrade-offs

    Notes: Abstract Potted two-year-old lemon plants (Citrus limon (L.) Burm. fil.) cv. Fino, growing under field conditions were subjected to drought by withholding irrigation for 13 d. After that, plants were re-irrigated and the recovery was studied for 5 d. Control plants were daily irrigated maintaining the soil matric potential at about -30 kPa. Young leaves of control plants presented higher leaf conductance (g1) and lower midday leaf water potential (Ψmd) than mature ones. Young leaves also showed higher leaf water potential at the turgor loss point (Ψtlp) than mature leaves. In both leaf types g1 decreased with increased vapour pressure deficit of the atmosphere. From day 1 of the withholding water, predawn and midday leaf water potentials (Ψpd and Ψmd) decreased, reaching in both cases minimum values of -5.5 MPa, with no significant differences between mature and young leaves. Water stress induced stomatal closure, leaf rolling and partial defoliation. No osmotic adjustment was found in response to water stress in either leaf type, but both were able to enhance the cell wall elasticity (elastic adjustment). After rewatering, leaf water potential recovered quickly (within 2 d) but g1 did not.

    Notes: This paper present a study focused on hot forward extrusion by upper bound method. Inparticular, hot forward extrusion of plates through square face dies under plane strain conditions.Slater defines the models used for large fractional reduction. Different models have been taken inaccount; they are dissimilar in relation to the dead metal zone (if covers or not the entire die face,partially or totally). Triangular rigid patterns of velocity discontinuities have been validated byanalytical methods and a range of use for the selected configurations has been established. Thismethodology has been applied to other process with good results. Thus, the mechanical parametersanalysed are fractional reduction, dead metal zone, length die and friction. Finally the calculation ofthe energy has been achieved by upper bound method. The results allow researching an optimisationof use of upper bound method in hot forward extrusion

    Water relations, growth and yield of Fino lemon trees under regulated deficit irrigation (1996)

    Notes: Abstract Fino lemon trees (Citrus limon L. Burm. fil.) on sour orange (Citrus aurantium L.), growing on a low water retention capacity soil, were submitted to three different irrigation treatments over four years: 100% ETc all year (T-0), 25% ETc all year except during the rapid fruit growth period when 100% ETc was applied (T-1) and 100% ETc all year, except during the rapid fruit growth period when 70% ETc was applied (T-2). A water saving of 30 and 20% was achieved in the T-1 and T-2 treatments, respectively. The plant responses to irrigation treatments were similar in all the years studied. Leaf water potential decreased during deficit irrigation periods in T-1 and T-2 treatments. Larger differences were found in values taken at predawn (ψ pd) than at midday (ψ md), indicating thatψ pd is a more useful indicator of plant water status. There was neither osmotic nor elastic adjustment in response to deficit irrigation treatment. A clear separation between the main periods of shoot and fruit growth was found, which can be considered an advantageous characteristic in applying regulated deficit irrigation strategies. Onset of the critical period of rapid fruit growth could be determined precisely by considering the decrease in relative fruit growth rate values. T-2 treatment did not induce a significant reduction in total yield, but it caused a delay in reaching marketable lemon fruit size. T-1 treatment did not affect total yield, with a reduction in yield on the first pick occurring in only one year. Chemical characteristics of lemon fruit were not significantly modified by irrigation treatment.

    Sap flow as an indicator of transpiration and the water status of young apricot trees (2000)

    Notes: Abstract The relationship between water loss via transpiration and stem sap flow in young apricot trees was studied under different environmental conditions and different levels of soil water status. The experiment was carried out in a greenhouse over a 2-week period (November 2–14, 1997) using three-year-old apricot trees (Prunus armeniaca cv. Búlida) growing in pots. Diurnal courses of leaf water potential, leaf conductance and leaf turgor potential also were recorded throughout the experiment. Data from four days of different enviromental conditions and soil water availability have been selected for analysis. On each of the selected days the leaf water potential and the mean transpiration rates were well correlated. The slope of the linear regression of this correlation, taken to indicate the total hydraulic resistance of the tree, confirmed an increasing hydraulic resistance under drought conditions. When the trees were not drought stressed the diurnal courses of sap flow and transpiration were very similar. However, when the trees were droughted, measured of sap flow slightly underestimated actual transpiration. Our heat-pulse measurements suggest the amount of readily available water stored in the stem and leaf tissues of young apricot trees is sufficient to sustain the peak transpiration rates for about 1 hour.
