primary or secondary hyperparathyroidism can present with a brown tumor of the mandible. involvement of other skull and facial bones is extremely rare. only a few cases with brown tumor of the orbital bones have been reported. an is year old girl with primary hyperparathyroidism presented with unilateral exophthalmos caused by brown tumor of the orbital roof, lite patient had a 1.5 cm palpable ...

Simulation of dynamic systems possessing unilateral frictional contacts is important to many industrial applications. While rigid body models are often employed, it is well established that friction can cause problems with the existence and uniqueness of the forward dynamics problem. In these situations, we argue that compliant contact models, while increasing the length of the state vector, su...

A numerical approach is presented for an inequality problem arising in the earthquake analysis of adjacent buildings. This problem concerns the unilateral contact-impact between neighboring buildings, when friction and P-delta effects are taken into account. The proposed numerical approach is based on a double discretization, in space and time, and on optimization methods. First, the Finite Ele...

Pediatric cataracts are responsible for more than 1 million childhood blindness in Asia. In developing countries like India, 7.4%–15.3% of childhood blindness is due to cataract.[1] The socioeconomic status of a large proportion of children with cataracts in India precludes reliable rehabilitation with contact lenses for aphakia. It is noteworthy that the Infant Aphakia Treatment Study (IATS)[2...

Behavioural modifications, including modifications of emotional reactivity, can occur following early experience such as handling (manual rubbing). Here, we investigated the effects of unilateral tactile stimulation at an early stage on emotional reactions later on. We handled newborn foals intensively on one side of their body. This early unilateral tactile experience had medium-term effects: ...

In geomechanics there are problems whose investigations lead to solving model problems based on variational formulations. Such problems are frequently formulated by variational inequalities as they physically describe the principle of virtual work in its inequality form. In the first part of the contribution the algorithm for the numerical solution of the discussed variational inequality proble...

The goal of this paper is to study a mathematical model nonlinear static frictional contact problem in elasticity with the mixed boundary conditions described by combination Signorini unilateral frictionless condition, and nonmonotone multivalued contact, friction laws subdifferential form. First, under suitable assumptions, we deliver weak formulation model, which an elliptic system Lagrange m...
