The mechanical strengths of nano-scale individual crystal or nanopolycrystalline metals, and other dimensionally-related materials are increased by an order of magnitude or more as compared to those values measured at conventional crystal or polycrystal g... see more

It is shown that very large stresses may be present in the thin films that comprise integrated circuits and magnetic disks and that these stresses can cause deformation and fracture of the material. For a crystalline film on a non-deformable substrate, a ... see more

Acoustic emission (AE) of magnesium alloy WE 43 in process to compress was studied. Typical grain size of alloy was between 3-25 microns. AE parameters (activity, total number of impulses, average amplitude) were analyzed in correlation with deformation&n... see more

The seepage phenomenon (uplift pressure - flow rate - exit gradient of hydraulic structures) is one of the main causes of failure or collapse of hydraulic structures, so it has been reduced using sheet piles under floor of hydraulic structures. In this st... see more

 The research presents an experimental study of the interaction between cavity and adjacent hydraulic structure in sandy soil. Experimental studies were performed to investigate the effects of the different factors (such as cavity locations and size ... see more

Comparing Navio dos Negros, Jorge Silva Melo’s adaptation of Benito Cereno in 2000 (Lisbon, Culturgest) to Melville’s narrative, several plots of dislocation and repossession emerge. In Melville, the core tale of the Atlantic slave trade initiated by the ... see more

In this paper a 2D finite element model (SEEP2D) is implemented to study the actual head loss along the sheet piles fixed at the ends of an apron of a heading up structure. Different scenarios for the thickness of the pervious layer under the apron, the l... see more
