Fish bone migration into urachus mimicking urachal malignancy: A rare case report [PDF]

Radiology Case Reports
Foreign bodies can find their way into and around the bladder usually via urethra by self insertion, migration from surrounding structures and by penetrating trauma. The clinical presentation being varied, symptoms nonspecific and history often concealed

Fracture mechanics analysis of two-dimensional cracked thin structures (from micro- to nano-scales) by an efficient boundary element analysis

Results in Applied Mathematics, 2021
In this paper, the boundary element method (BEM) based on the elasticity theory is developed for fracture analysis of cracked thin structures with the relative thickness-to-length ratio in the micro- or nano-scales.

Thin structured rigid body for acoustic absorption [PDF]

Applied Physics Letters, 2017
We present a thin acoustic metamaterial absorber, comprised of only rigid metal and air, that gives rise to near unity absorption of airborne sound on resonance. This simple, easily fabricated, robust structure comprising a perforated metal plate separated from a rigid wall by a deeply subwavelength channel of air is an ideal candidate for a sound ...

3D ultrastructural organization of whole Chlamydomonas reinhardtii cells studied by nanoscale soft x-ray tomography [PDF]

, 2012
The complex architecture of their structural elements and compartments is a hallmark of eukaryotic cells. The creation of high resolution models of whole cells has been limited by the relatively low resolution of conventional light microscopes and the ...

Transluminal Migration of Oesophageal Foreign Bodies: A Series of Three Patients

Journal of Clinical and Health Sciences, 2023
Inadvertent ingestion of foreign bodies, particularly fish bone, are a common complaint in the otolaryngology emergency practices in Southeast Asia. Due to its thin, linear, and sharp pointed end, fish bone has the potential to penetrate through
