Background: Distal radius fractures constitute 17% of all fractures and 75% of forearm fractures in adults. Due to the vital role of the hands in a wide range of daily tasks, quick recovery and fewer complications for the patients are important. The purpose of this study was to compare the two common treatments of distal radius fractures namely, percutaneous pinning and pin-in-plaster. Methods...
Nonlinear weirs are regarded as important hydraulic structures for water level adjustment and flow control in channels, rivers and dam reservoirs. One example of non-linear weirs is shaped as curved-zigzag. The crest axis of these weirs is non-linear. At a given width, the crest length is greater than that of the conventional linear weirs. Thus, they achieve a higher flow rate for an identical ...
Background: There is inconsistent information about the role of psychological factors in the incidence of reflex sympathetic dystrophy (RSD) in patients with distal radius fractures. The present study was thus undertaken to evaluate the relationship between some of these factors and the occurrence of reflex sympathetic dystrophy in patients with distal radius fracture. Methods: One hundred and ...
conclusions the radiological findings of the present study showed that the use of a coral-dcfgp mixture led to superior bone defect healing and rapid graft incorporation when compared to the use of solely coral or dcfgp. background currently, coral is used as an osteoconductive material. demineralized calf fetal growth plate (dcfgp) has also been used as a source of osteoinduction. objectives t...
Understanding the dynamics of microbubble oscillation in an elastic microvessel is important for the safe and effective applications of ultrasound contrast agents in imaging and therapy. Numerical simulations based on 2D finite element model are performed to investigate the effect of acoustic parameters such as pressure and frequency on the dynamic interaction of the fluid-blood-vessel system. ...
let x be an n-square complex matrix with the cartesian decomposition x = a + i b, where a and b are n times n hermitian matrices. it is known that $vert x vert_p^2 leq 2(vert a vert_p^2 + vert b vert_p^2)$, where $p geq 2$ and $vert . vert_p$ is the schatten p-norm. in this paper, this inequality and some of its improvements ...
In most of the sheet forming processes, production of the parts with minimum thickness variation and low required force is important. In this research, minimization of the sheet thinning and forming force in the hydraulic deep drawing process has been studied. Firstly, the process is simulated using the finite element method (FEM) and simulation model is verified using the experimental results....
Let T and S be two bounded linear operators from Banach spaces X into Y and suppose that T is Fredholm and dimN(T − λS) is constant in a neighborhood of λ = 0. Let d(T ;S) be the supremum of all r > 0 such that dimN(T − λS) and codim R(T − λS) are constant for all λ with |λ| < r. It is a consequence of more general results due to H. Bart and D.C. Lay (1980) that d(T ;S) = limn→∞ γn(T ;S) , wher...
Background: There are a number of different implant choices for surgical treatment of distal radius fractures, oftendetermined by surgeon preference or availability. Although no one volar plate demonstrates superior outcomes, thereare significant cost differences absorbed by hospitals and surgical centers. This purpose of this study is to characterizethe economic implications of implant selecti...
