Salt crystallization is one of the most powerful weathering agents that may cause a rapid change in the mechanical properties of stones, and thus limit their durability. Consequently, determining the mechanical properties of stones due to salt crystallization is important for natural building stones used in marine environmental and mild climatic conditions, which expose excessive salt crys...

A unification of the gravitational with the electromagnetic interaction within a classical framework is proposed. It is based on a Fs-geometry, with x^ — qjm. The sole source term is mechanical stress energy, positioned along X5. The trajectories of testbodies are placed in V4 (xo = const)-slices. The final field equation couples a geometric G-tensor to mechanical stress energy, its momentum wi...

The elastic properties of DNA are essential for its biological function. They control its bending and twisting as well as the induction of structural modifications in the molecule. These can affect its interaction with the cell machinery. The response of a single DNA molecule to a mechanical stress can be precisely determined in single-molecule experiments which give access to an accurate measu...
