Significant mortalities of the Pacific oyster, Crassostrea gigas, have been reported worldwide since the 1950s. The impact these re-occurring mortality events have had on the C. gigas industry has highlighted the necessity to determine the factors that may be causing these mortalities. This study investigated the possible role of ostreid herpes virus(More)
PURPOSE Floaters caused by degenerative or postoperative changes in the vitreous can interfere with all aspects of visual functioning. The aim of this study is to report the longterm outcome of pars plana vitrectomy (PPV) for persistent vitreous opacities. METHODS In a retrospective, non-randomized, interventional case study we reviewed all cases of(More)
Two perfluorocarbon liquids (perfluoro-n-octane and perfluorodecaline) were evaluated as technical aids in vitreoretinal surgery in 42 patients. Perfluorocarbon liquids were found to stabilize the retina and simplify removal of repiretinal membranes, which in many cases permitted the subsequent use of an expanding gas instead of silicone oil at the(More)
PURPOSE To summarize and analyse the results of our experience in treating patients with a "dropped nucleus". METHODS The case records of nineteen patients who underwent surgery for a "dropped nucleus" at the Ophthalmology Departments of Sahlgren's University Hospital, Gothenburg, and Orebro Medical Centre, Orebro, Sweden during 1994 were retrospectively(More)
A model which incorporates the effects of electron cyclotron current drive (ECCD) into the magnetohydrodynamic (MHD) equations is implemented in the NIMROD code [C. R. Sovinec et al., J. Comp. Phys. 195, 355 (2004)] and used to investigate the effect of ECCD injection on the stability, growth, and dynamical behavior of magnetic islands associated with(More)
We report the case of a 76-year old woman who presented with a palindromic onset of seropositive rheumatoid arthritis. After suffering from a fulminant pulmonary infection she developed serologic tests for ornitosis, mycoplasma, pneumocystis carinii and low titer yersinia. Also the rheumatoid factor titer increased and the antinuclear antibody test became(More)
Both wild and cultured mussels (Mytilus edulis, Mytilus galloprovincialis and hybrids), are found along most of the Irish coastline. M. edulis is widespread along all Irish coasts and is the only mussel species present on both the east coast of Ireland and the Welsh coast in the Irish Sea. M. galloprovincialis and hybrids are found along the Irish coastline(More)
We investigate properties of algorithms that are used to solve coupled evolutionary partial differential equations posed on neighboring, nonoverlapping domains, where the solutions are coupled by continuity of state and normal flux through a shared boundary. The algorithms considered are based on the widely used approach of iteratively exchanging boundary(More)
