AIM To establish whether the presence of a retinal break can be predicted either by the presence of a positive Shafer's sign (pigment granules in the anterior vitreous) or symptomatology in patients presenting with an acute posterior vitreous detachment (PVD). METHODS 200 eyes of 200 phakic patients with a symptomatic PVD of less than 1 month's duration underwent documentation of symptomatolo...

To compensate for the lack of abstraction in field origami, this paper, we propose a categorical description that can be introduced to map folding. Specifically, use particular expression abstract folding process with logical matrices. When operations are restricted two certain kinds, simple folds and unfolds, define categories partly folded states as poset categories. The property posets induc...

purpose:  to evaluate the significance of the presence of pigment granules in  the anterior  vitreous as a reliable indicator of retinal breaks in patients with acute symptomatic posterior vitreous detachment  (pvd) . methods: this cross sectional study included 209 phakic patients with acute symptomatic pvd. the patients underwent anterior vitreous examination and fundoscopy. patients with dia...

Introduction Understanding divertor detachment is essential to predicting the operation of future diverted tokamaks. The current plan for ITER operation assumes that the plasma is detached from the divertor, that f e be near the Greenwald limit [1] and that the main plasma is not diluted by impurities. However, we do not know whether these conditions can be achieved simultaneously. In this set ...

Reftable reconstruction of former topography in deformed regions is commonly difficult, due to degradation of former erosional and depositional surfaces. In contrast o most modem landscapes, however, ancient localities can sometimes provide clearer insights on subsurface geometries of deposition, deformation, and erosion and on theft variations through time. In some exceptional circumstances, a...
