In this paper we consider a viscoelastic string whose deformation is controlled at one end. We study the relations and the controllability of the couples traction/velocity and traction/deformation and we show that the first couple behaves very like as in the purely elastic case, while new phenomena appears when studying the couple of the traction and the deformation. Namely, while traction and ...

Ann R Coll Surg Engl 2012; 94: 359–372 Many lower extremity, pelvic and acetabular fractures require traction as first aid management prior to definitive fixation. While skin traction and Thomas splints are generally available, weights to provide countertraction are often missing or in parts of the hospital remote to the emergency department. A sharps bin (Sharpsguard® orange 11.5; Daniels, Oxf...

The nonlinear partial differential equations of the anisotropic biphasic theory of tissue-equivalent mechanics are solved with axial symmetry by an adaptive finite element system. The adaptive procedure operates within a method-of-lines framework using finite elements in space and backward difference software in time. Spatial meshes are automatically refined, coarsened, and relocated in respons...

.m ed kn ow An 18-year-old girl working as a lifeguard in a swimming pool presented with a fall on the slippery wet floor of the pool, landing on her right shoulder and back of her head. She had pins and needles in the fingertips of the right upper limb. She did not have any neurological deficits. Computed topographic scan (CT) of cervical spine showed evidence of rotatory atlantoaxial dislocat...

AIM To evaluate Bryant traction at home in terms of feasibility, morbidity, effect on length of hospital stay, outcome and costs. PATIENTS AND METHODS Retrospective analysis of 54 children treated for femoral shaft fracture (1991-2004). Results of 'home traction' (A, n=38) and 'hospital traction' (B, n=16) were compared. Data were collected regarding demographics, length of hospital stay, tra...

Traction folliculitis is a component of traction alopecia syndrome and has received minimal attention in primary source medical literature. The popularity of hairstyles that produce hair traction and the knowledge that early intervention improves prognosis amplify the importance of recognizing this entity. Traction folliculitis presents as perifollicular erythema and pustules on the scalp in ar...

Objectives: To compare the outcomes of prone and supine lumbar traction in patients with chronic discogenic low back pain. Methods: The test was prospective and randomized control trial. The structure of trial was Urban Physical Medicine and Rehabilitation clinic. Participants was included of A total of 124 subjects with chronic low back pain (LBP) and evidence of a degenerative and/or herni...

bending analysis of multilayer graphene sheets (mlgss) subjected to non-uniform shear and normal tractions is presented. the constitutive relations are considered to be non-classical based on nonlocal theory of elasticity. based on the differential transformation method, numerical illustrations are carried out for circular and annular geometries. the effects of nano scale parameter, radius of c...
