this report presents a 3.5-year-old boy who was hospitalized for limping. medical history and physical exams were not suggestive for any definitive diagnosis. laboratory and radiographic exams did not support any specific diagnosis either. subsequently bone scan was performed and increased activity in the ankle due to cuboid fracture was incidentally observed.

To explore the influence of cyclic impact and axial static pressure on damage chemically corroded sandstone, a series tests were conducted white sandstone by using Split Hopkinson Pressure Bar. Besides, longitudinal sections fractures samples observed with scanning electron microscope for purpose investigating characteristics structural changes subjected to coupling force chemistry. The results...

conclusions the causes leading to fracture of the humerus during the act of a throw are discussed and the management strategies utilized. introduction five patients presented to the emergency department of a tertiary referral teaching hospital with atraumatic fractures of their humerus sustained during a recreational dodgeball tournament. case presentation the patients were young healthy indivi...

background: floating knee, referred to as ipsilateral fractures of the femur and tibia, is usually associated with several complications and mortality. this study was designed to present our experience with treatment of this injury throughout; age, sex, mechanism of injury, associated injuries, method and results of treatment, and complications of floating knee are discussed. materials and meth...

introduction: fractures of the orbital floor, which are caused by various mechanisms, result in the herniation of periorbital tissue into the paranasal sinuses and its subsequent complications. early diagnosis using various techniques and reduction of fractures are necessary to preserve ocular function and esthetic. use of an endoscope has been associated with some advantages, including a decre...

In this paper, we present new variants of global bi-conjugate gradient (Gl-BiCG) and global bi-conjugate residual (Gl-BiCR) methods for solving nonsymmetric linear systems with multiple right-hand sides. These methods are based on global oblique projections of the initial residual onto a matrix Krylov subspace. It is shown that these new algorithms converge faster and more smoothly than the Gl-...

Treatment methods for breast cancer are not specific and each one has its own drawbacks. For this reason, scientists are seeking ways in which specifically affect cancer cells. Photothermal therapy is a method that uses near-infrared (NIR) laser energy to create sufficient heat to destroy cancer cells. In this study, the photothermal effect of gold nanorods (GNRs) was investigated for breast ca...

Phase-field models are frequently adopted to simulate fracture mechanics problems in the context of finite element method. To depict fracture, this method involves solving a coupled set Helmholtz-like damage-field equation and augmented linear momentum balance equation. Solutions these equations then used as descriptions crack propagation phenomena within solids. However, imposes constrain usin...

According to recent estimates, the potential for oil production from fractured reservoirs in North America is of the order of tens of billion of barrels. With domestic production depending more and more on mature fields, better technology for characterizing fracture flow paths, especially in deep, nonconventional plays and in carbonate rocks is key to producing hydrocarbons economically. Fractu...
