We determined the direct relationships between wrist position and displacement of the median nerve during active contraction of the flexor tendons at the wrist with an intact, transected transverse carpal ligament (TCL). Nine fresh cadavers were mounted in an apparatus to allow variable wrist position. Excursions of the tendons and displacement of the median nerve were measured by tracking mark...

The Rad51 nucleoprotein filament mediates DNA strand exchange, a key step of homologous recombination. This activity is stimulated by replication protein A (RPA), but only when RPA is introduced after Rad51 nucleoprotein filament formation. In contrast, RPA inhibits Rad51 nucleoprotein complex formation by prior binding to single-stranded DNA (ssDNA), but Rad52 protein alleviates this inhibitio...

the arnold-chiari malformation is a congenital abnormality of cns, characterized by downward displacement the parts of the cerebellum, fourth ventricle, pons and medulla oblongata into the spinal canal. this malformation is one of causative factor of death in neonates and infants. a thorough understanding of the direct and indirect sonographic findings is necessary for diagnosis of chiari ii ma...

This paper explores the relationship between violence and displacement during civil war focusing on two different forms of population movements (i.e. incoming and outgoing), and two different forms of violence (i.e. direct and indirect). The paper explores the relationship between displacement and violence at the local level in the context of a civil war fought conventionally using a novel data...

Two approaches are commonly used for handling frictional contact within the framework of the Discrete Element Method (DEM). One relies on the Complementarity Method (CM) to enforce a non-penetration condition and the Coulomb dry-friction model at the interface between two bodies in mutual contact. The second approach, called the Penalty Method (PM), invokes an elasticity argument to produce a f...

lateral and anterior displacements of mandible may cause malocclusion. the aim of this study was to determine the prevalence of these displacements in a population of 597 childrens age 12 in mashhad secondary schools. displacment of mandible was shown to be in 11.8 percent of the population (6.2 percent anterior and 5.6 percent lateral displacement).anterior displacement of mandible was diagnos...

Competitive displacement is the most severe outcome of interspecific competition. For the purposes of this review, we define this type of displacement as the removal of a formerly established species from a habitat as a result of direct or indirect competitive interactions with another species. We reviewed the literature for recent putative cases of competitive displacement among insects and ar...

Using a dynamic biomechanical model of malunion of the shoulder, we have determined the change in deltoid force required for abduction with various combinations of superior and posterior displacement of fractures of the greater tuberosity of the humerus. We tested eight fresh human cadaver shoulders in a dynamic shoulder-testing apparatus during cycles of glenohumeral abduction from 0 degrees t...
