Purpose We report a case of ophthalmomyiasis interna successfully removed in toto with pars plana vitrectomy. Observations An 84-year-old woman with recent close contact with lambs presented with a new floater. Examination revealed subretinal tracks pathognomonic for ophthalmomyiasis and a larva suspended in the vitreous. The larva was successfully removed in toto with pars plana vitrectomy b...

Unions’ decline is prevalent in most western democracies (Blanchflower 2007). Decline takes many features – decreasing bargaining power, reduced role in political negotiations, reduced coverage of collective agreements, shallow bargaining (in terms of topics covered and the extent of workers rights), and declining membership rates. In this article I would like to focus on the latter aspect. The...

In terms of features of field and track athletes’ training, th is paper, integrating techniques of network, database, computers, multi-media, image processing, etc, devises a management information system of field and track training based on B/S model and provides an training informat ion processing system.

investigations on vibration behaviors of railway track systems were attempted in this research. this was made by conducting a comprehensive field investigation into the free vibration of track systems and response of tracks to train moving loads. in-situ modal analysis was used in a railway track field as an efficient method of investigating dynamic properties of railway track systems. natural ...

Recent improvements in the radiation transport code HZETRN/BRYNTRN and galactic cosmic ray environmental model have provided an opportunity to investigate the effects of target fragmentation on estimates of single event upset (SEU) rates for spacecraft memory devices. Since target fragments are mostly of very low energy, an SEU prediction model has been derived in terms of particle energy rathe...
