Deficit irrigation or intentional under-irrigation offers the potential for sustainable water resources management. The DSSAT CERES-Maize and AquaCrop models were coupled to simulate effects of deficit on corn yield productivity. calibrated validated using observed values crop biomass under 40%, 50%, 60%, 70%, 80% depletion available soil water. Model simulation results showed that a 15% level ...
Abstract Concrete slabs are widely used in modern railways to increase the inherent resilient quality of tracks, provide safe and smooth rides, reduce maintenance frequency. In this paper, elastic performance a novel slab trackform for high-speed is investigated using three-dimensional finite element modelling Abaqus. It then compared ballasted track. First, track models developed replicate ful...
Introduction: The main-belt object Ceres (radius≈475 km, density≈2100 kg m-3 , semi-major axis 2.7 AU), is an exciting place to explore planetary hab-itability. Abundant volatiles could have shaped Ceres in a way analogous to that suspected on icy moons. Hydrothermalism: Ceres' surface seems blanketed by products of the interaction between silicate rock and liquid water, including carbonates [1...
The Clouds and the Earth’s Radiant Energy System (CERES) generates one of the few global satellite radiation products. The CERES ARM Validation Experiment (CAVE) has been providing long-term in situ observations for the validation of the CERES products. However, the number of these sites is low and their distribution is globally sparse, and particularly the surface net radiation product has not...
