In this work, rising of a single bubble in a quiescent liquid under microgravity condition was simulated. The related unsteady incompressible full Navier-Stokes equations were solved using a conventional finite difference method with a structured staggered grid. The interface was tracked explicitly by connected marker points via hybrid front capturing and tracking method. One field approximatio...

Numerical and experimental results show that during the collapse phase of a vapor bubble near a rigid boundary, in the absence of strong buoyancy forces, a liquid micro jet is developed on the side of the bubble far from the rigid surface and directed towards it. Numerical and experimental results also show that, in the case of a bubble near a free surface, during the collapse phase of the bubb...

PURPOSE To present a case of Maroteaux-Lamy syndrome (MLS), which underwent deep anterior lamellar keratoplasty (DALK) for visual rehabilitation. METHODS A 15-year-old girl with MLS was admitted with severe corneal opacity. We performed DALK on her left eye for visual rehabilitation. Big-bubble technique was used to perform lamellar separation. RESULTS Corneal graft was clear 24 months afte...

A big part of the problem lies with companies themselves, which remain trapped in an outdated approach to value creation that has emerged over the past few decades. They continue to view value creation narrowly, optimizing short-term financial performance in a bubble while missing the most important customer needs and ignoring the broader influences that determine their longer-term success. How...

As an applicaton of sonification, a simulation of the early universe was developed to portray a phase transition that occurred shortly after the Big Bang. The Standard Model of particle physics postulates that a hypothetical particle, the Higgs boson, is responsible for the breaking of the symmetry between the electromagnetic force and the weak force. This phase transition may have been respons...

In this paper, we propose a new stereo measurement method of objects in liquid whose refractive index is unknown. In recent years, demands for underwater tasks, such as digging of ocean bottom resources, exploration of aquatic environments, rescues, and salvages, have increased. Therefore, underwater robots or underwater sensing systems that work instead of human become important, and technolog...

Surface cleaning using cavitation bubble dynamics is investigated numerically through modeling of bubble dynamics, dirt particle motion, and fluid material interaction. Three fluid dynamics models; a potential flow model, a viscous model, and a compressible model, are used to describe the flow field generated by the bubble all showing the strong effects bubble explosive growth and collapse have...

Purpose: To report a case of double descemet membrane forming a double anterior chamber following ‘Big bubble’ DALK converted to PKP. Results: A 52-year-old man with keratoconus underwent DALK operation converted to PKP due to macro perforation of the descemet membrane. On the postoperative evaluation a remnant of the host’s descemet membrane formed a double anterior chamber. After a few months...

RATIONALE To report a case of late spontaneous reattachment of Descemet membrane (DM) detachment after deep anterior lamellar keratoplasty (DALK). PATIENT CONCERNS A 50-year-old woman with stromal corneal scarring underwent a DALK with the big bubble technique. The DM detachment and double anterior chamber were observed on the first day after operation. DIAGNOSES Descemet membrane detachmen...
