Sommario/riassunto

The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals.Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as we

Sommario/riassunto

The evolution of inequality and its causes are of crucial importance to all scholars working across the social sciences. By focusing on the divergent development of North America and Latin America in the nineteenth and twentieth centuries, Camps-Cura offers a comparative perspective of the relationship between human capital expansion and inequality in the long run. The book also explores the variables of education and inequality on children, work and gender.
