increasing patch edges in natural habitats, as a result of habitat fragmentation, are a major threat for wildlife populations, especially avifaunal communities. habitat edges provide different conditions compared to the core area which can directly or indirectly cause changes in species number, population and composition. this fact will demand a dissimilar management strategy. this study was co...

PURPOSE To report a rare presentation of unifocal Langerhans cell histiocytosis (LCH) simulating a limbal papilloma. CASE REPORT A 24-year-old man presented with a limbal mass in his left eye which had initially been suspected to be a papilloma based on clinical findings. The mass was excised and a histopathological diagnosis of "acute bullous inflammation with granulation tissue" was made. T...

Numerical difficulties are present in the particle finite element method even though it has been shown to be a powerful and effective approach to simulating fluid-structure interaction. To overcome problems of mass loss on the free surface and the added-mass effect, an improved fractional step method (FSM) that handles addedmass terms in a mathematically exact way is developed. A further benefi...

A moving mesh finite element algorithm is proposed for the adaptive solution of nonlinear diffusion equations with moving boundaries in one and two dimensions. The moving mesh equations are based upon conserving a local proportion, within each patch of finite elements, of the total “mass” that is present in the projected initial data. The accuracy of the algorithm is carefully assessed through ...

This case describes a 60-year-old gentleman who presented with a pulsating mass behind his knee. Before this, he had a fasciotomy for suspected compartment syndrome of leg following knee arthroscopy, but this failed to resolve his leg symptoms. He was hemodynamically stable on presentation. His left calf was swollen with a circumference of 3 cm greater than right. There was a large pulsating ma...

Abstract This paper presents a single-point Material Point Method (MPM) for large deformation problems in two-phase porous media such as soils. Many MPM formulations are known to produce numerical oscillations and inaccuracies the simulated results, largely due integration stress recovery performed at non-ideal locations, cell crossing errors, mass moving from one background grid another. The s...

background cancer pain may be a major problem for health care providers worldwide. according to different studies reporting the pain severity, one-third of patients reported to have moderate to severe pain. management of cancer pain is one of the most important goals of palliative care. recently, different research results on the efficacy of opioid analgesics in chronic pain management have pla...
