background: osteoporosis is a chronic disease that contributes substantially to decrease physical activity and decline in the quality of life. osteoporosis can be diagnosed easily with the use of dual-energy x-ray absorptiometry (dxa) equipment. the aim of this study was to investigate the magnitude of bone loss on proximal femur and lumbar spine ls in pre- and post-menopausal women from isfaha...

introduction: intramedullary nailing (imn) of high tibia fracture has some mechanical and biological advantages over the other form of fixation. however, valgus, apex anterior malalignment and anterior displacement of proximal fragment commonly occur after isolated imn fixation of proximal high tibia fracture. the purpose of this study is to determine the effectiveness of using 3.5-mm locking c...

PURPOSE The physical and potential biological advantages of proton and carbon ions have not been fully exploited in radiation therapy for the treatment of cancer. In this work, an approach to predict proton and carbon ion relative biological effectiveness (RBE) in a representative spread-out Bragg peak (SOBP) is derived using the repair-misrepair-fixation (RMF) model. METHODS AND MATERIALS Fo...

Five experiments investigated how human adults use landmark arrays in the immediate environment to reorient relative to the local environment and relative to remote cities. Participants learned targets' directions with the presence of a proximal 4 poles forming a rectangular shape and an array of more distal poles forming a rectangular shape. Then participants were disoriented and pointed to ta...

Let $kgeq 1$ be an integer, and $G=(V,E)$ be a finite and simplegraph. The closed neighborhood $N_G[e]$ of an edge $e$ in a graph$G$ is the set consisting of $e$ and all edges having a commonend-vertex with $e$. A signed Roman edge $k$-dominating function(SREkDF) on a graph $G$ is a function $f:E rightarrow{-1,1,2}$ satisfying the conditions that (i) for every edge $e$of $G$, $sum _{xin N[e]} f...

let $d$ be a digraph with vertex set $v(d)$. for vertex $vin v(d)$, the degree of $v$,denoted by $d(v)$, is defined as the minimum value if its out-degree and its in-degree.now let $d$ be a digraph with minimum degree $deltage 1$ and edge-connectivity$lambda$. if $alpha$ is real number, then the zeroth-order general randic index is definedby $sum_{xin v(d)}(d(x))^{alpha}$. a digraph is maximall...

In coronary intervention practice, optimal stent deployment in terms of adequate expansion and complete apposition is of paramount importance to obtain favorable immediate and long-term results. Even with the introduction of stent delivery systems based on a semi-compliant balloon allowing stent deployment at higher pressures (≥ 14 atm), adjunctive post dilation with a non-compliant (NC) balloo...

Suggested scheme for the treatment of onychomycosis A stepped therapeutic approach to the treatment of onychomycosis is suggested. The risks of failure of treatment include the fungal involvement of the lunula portion, the lateral edge of the nail and the subungual area. Infection of the subungual area may lead to extensive onycholysis or dermatophytoma presenting as a hard subungual mass or as...

one of the most fundamental features of digital image and the basic steps in image processing, analysis, pattern recognition and computer vision is the edge of an image where the preciseness and reliability of its results will affect directly on the comprehension machine system made objective world. several edge detectors have been developed in the past decades, although no single edge detector...
