Background: Overuse injuries in sports seem to be 1.5 to 2.5 times more common than traumatic injuries in the lower extremity (LE) in children and adolescents. Floorball is the most popular indoor sport in Sweden and is associated with many potential risks of injuries. However, to our knowledge, no previous studies have examined the appearance of injury in young floorball players. Objective: The a

Dielectric elastomers belong to a larger group of materials, the so-called electroactive polymers, which have the capability of transforming electric energy to mechanical energy through deformation. VHB 4910 is one of the most popularmaterials for applications of dielectric elastomers and therefore one of the most investigated. This paper includes a new micromechanically motivated constitutive mod

Dielectric elastomers offer clear advantages over more traditional and conventional materials when soft, lightweight, noiseless actuator applications with large deformations are considered. However, the viscous time-dependent behaviour associated with most elastomers limit the number of possible applications. For this purpose, the possibility of controlling the viscous response by regulating the a

Bellicist theories of comparative development predict increases in taxation as the result of military rivalries. Others claim that this causal relationship is contingent on particular geographical, institutional, and historical conditions. In this paper, we explore the conditional effects of military rivalries on taxation during the 19th and 20th centuries using time-series cross-section models. W
