In the last decades, temperatures of Earth’s atmosphere and its oceans have increased significantly. Warming strongly affects Arctic, where we can observe fast glacial melt during summer. Meltwater brings debris from land into coastal ocean, creating zones with brown water. This seawater darkening affect living conditions marine organisms possibly threaten life in future. To address this issue,...

During tube hydroforming process, the friction conditions between and die have a great importance on material plastic flow distribution of residual stresses final component. Indeed, three-dimensional finite element model process in case square section has been performed, using dynamic static approaches, to study effect both induced by process. First, comparative numerical experimental results c...

A network of 24 beech (Fagus sylvatica L.) tree-ring chronologies has been developed for the Italian peninsula. Principal component and cluster analyses were used to identify geographical and altitudinal patterns of tree growth. Correlations and response functions were then applied to the main modes of tree-ring variability to uncover climatic signals. In a landscape occupied by humans for mill...

We present results from simulations to examine how the separation between two convectively unstable layers affects their interaction. We show that two convectively ustable layers remain connected via the overshooting plumes even when they are separated by several pressure scale heights.

There are currently three major competing views on the nature of earthquake fault zones. The first is that faults are (possibly segmented and heterogeneous) Euclidean zones in a continuum solid. The second focuses on granular aspects of faults and deformation fields. The third is that faults are fundamentally rough fractal objects at all relevant scales. The existing data can not distinguish un...
