However, there is no report on polymethyl methacrylate (PMMA) intraocular lens (IOL) calcification. Objective: Report the clinical feature, histopathologic and spectrophotometer analysis of opacified three-piece PMMA IOL. Method: A 60-year...

nowadays, tube bonding in vehicles structure is noticeably considered by many researches. in this paper, local tube compression process by a rubber ring has been studied. firstly, simulation of the process was performed by fem. then, experimental test has been carried out to validate the numerical results. numerical and experimental results were compared showing a good agreement. in the second ...

chest tube (ct) or tube thoracostomy placement is often indicated following traumatic injuries. premature movement of the chest tube leads to increased hospital complications and costs for patients. placement of a chest tube is indicated in drainage of blood, bile, pus, drain air, and other fluids. although there is a general agreement for the placement of a chest tube, there is little consensu...

Probably the most common rock-imprint fossil-insect remain is an incomplete isolated wing. This pitfall has been traditionally addressed by manually reconstructing missing parts, which not ideal to comprehend long-term evolutionary trends in group, particular for morphological diversity (i.e., disparity) approaches. Herein we describe a new Triassic relative of dragon- and damselflies (Odonata)...
