In tissue engineering, scaffolds can be obtained by means of 3D printing. Different structures are used in order to reduce the stiffness of the solid material. The present article analyzes the mechanical behavior of ...

The formation of uranyl-peroxide complexes was studied at alkaline media by using UV-Visible spectrophotometry and the STAR code. Two different complexes were found at a H2O2/U(VI) ratio lower than 2. A graphical method ...

In this project we determined some basic parameters for characterizing an organic thin-film transistor (OTFT) one week after fabrication and compared them with the parameters right after fabrication, in particular the ...

The friction factor is an essential parameter to take into account for modelling the ventilation system. One of the principal features that define the friction factor is the roughness, which not only does it have influence ...

The definition of the glass transition temperature, Tg, is recalled and its experimental determination by various techniques is reviewed. The diversity of values of Tg obtained by the different methods is discussed, with ...

The strain rate dependence of the plastic yield and failure properties displayed by most metals affects energies, forces and forming limits involved in high speed forming processes. In this contribution a technique is ...

The reprocessing of spent nuclear fuel is a very important step in the nuclear fuel cycle and one of the greatest ways to ensure the sustainability of the civil nuclear industry. In France, the PUREX process is used to ...

The natural frequencies of a turbine can be calculated from numerical methods. By comparing these natural frequencies with excitation sources, one can know the danger of a resonance and a possible failure in a component ...

The problem of overlap factor (OVF) computation and its near-range sensitivity for medium-size aperture ( f ∕ 10 , f ∕ 11 ) bi-axial tropospheric lidar systems using ray-tracing sim- ulation software is presented. ...
