After devising expectational measures of production, price and exchange rate uncertainty, this paper presents a model to derive an optimal hedging strategy for a primary producer who is subject to variability on the price and the amount of its output and on the exchange rate risk when the final proceeds of its sales are not denominated in its currency of numeraire. In this model, it is assumed ...

Light pruning and deficit irrigation regimes are practices which are widely used in high yielding commercial vineyards in the warm climate regions of Australia. Little information is available on their impacts on carbohydrate dynamics in vegetative organs within and between seasons, and on the resulting plant capacity to maintain productivity and ripen fruits. This study was conducted to addres...

In this paper, the precrack propagation behavior of an SMA490BW welded joint in core zone and heat-affected was analyzed through experiments based on FRANC 3D ABAQUS cosimulation method, life prediction these cracks also investigated. The results show that experimental crack path rate weld agree well with simulation results, a small relative error. span prefabricated higher than zone. Furthermo...
