The coarsening of folds in hanging drapes
We consider the elastic energy of a hanging drape – a thin elastic sheet, pulled down by the force of gravity, with fine-scale folding at the top that achieves approximately uniform confinement. This example of energy-driven pattern formation in a thin elastic sheet is of particular interest because the length scale of folding varies with height. We focus on how the minimum elastic energy depen...
متن کاملResistance of disposable drapes to bacterial penetration.
PURPOSE To test the bacterial penetrability of disposable non-woven drapes used specifically for total hip arthroplasty. METHODS 12 round agar plates were inoculated with 107 colony-forming units/ml of coagulase-negative staphylococci (CNS) and incubated in air at 37 degrees Celsius for 18 hours to obtain a semi-confluent growth of organisms. Six brands of disposable drapes were tested; each ...
متن کاملBilateral Choroidal Folds in a Diabetic Patient
Abstract In this presentation, a case of bilateral choroidal folds in patient with diabetic retinopathy was reported. By our knowledge, this case presentation is the first report of choroidal folds in diabetic retinopathy, which bilateral symmetric and horizontal folds arranged in macula. The thick choroid that is developed in diabetics may be a cause of these folds but the source of differenc...
متن کاملLessons that cross the surgical drapes
BACKGROUND Modern medicine has created a need for innovative methods of training that create safe, proficient specialists with adequate experience, and who are fit for purpose in this new system. Patient safety and patient-focused care are central to current practice and promoted by the use of simulation, human factors, team-based, multidisciplinary and interspecialty training. An acknowledgeme...
متن کاملCoarsening fronts
We characterize the spatial spreading of the coarsening process in the Allen-Cahn equation in terms of the propagation of a nonlinear modulated front. Unstable periodic patterns of the Allen-Cahn equation are invaded by a front, propagating in an oscillatory fashion, and leaving behind the homogeneous, stable equilibrium. During one cycle of the oscillatory propagation, two layers of the period...
