In Spain: A changing society, several authors analyze the principal transformations that have occurred from the beginning of the democratic transition and the approval of the Spanish Constitution of 1978, until the end o...

Abstract Friction Stir Welding (FSW) is the most promising solid-state metals joining method introduced in this era. Compared to the conventional fusion welding methods, this FSW can produce joints with higher mechanical...

The article deals with tribochemical influence of the surface activity of biosynthetic oils on the operational efficiency and reliability of lubricated friction nodes under the critical conditions. It is proved that the ...

Neutrinos in astrophysical environments, such as Supernovae (SNe), may interact through pair interactions. These interactions are density and temperature-dependent. Under certain conditions, a neutrino-condensate may for...

Mathematical representation is an idea interpretation form of solving mathematical problems. The process of mathematical representation is essential to pay attention to, especially in carrying out transformations between...

Nothing from the subsequent Augustan age can be fully explained without understanding the previous Triumviral period (43-31 BC). In this book, twenty experts from nine different countries and nineteen universities examin...
