Polymetallic sulfides present in mid-ocean ridges (MORs) have become important strategic resources for humans, and a scientific metallogenic model is necessary the investigation exploration of these resources. Compared to fast- slow-spreading MORs, ultraslow-spreading MORs show substantial differences magma supply, tectonic activity, oceanic crust structures. However, information on hydrotherma...

purpose: to evaluate the clinical features, and functional and anatomical outcomes of surgical intervention for pediatric rhegmatogenous retinal detachment (rrd). methods: in this retrospective case series, pediatric patients with rrd who had undergone surgical intervention were included. cases were categorized into five main etiological groups: congenital or developmental (48 eyes), traumatic ...

INTRODUCTION Rhegmatogenous retinal detachment (RRD) is the most common form of retinal detachment, where a retinal "break" allows the ingress of fluid from the vitreous cavity to the subretinal space, resulting in retinal separation. It occurs in about 1 in 10,000 people a year. METHODS AND OUTCOMES We conducted a systematic review and aimed to answer the following clinical questions: What a...

In reporting on the theorem prover SCOTT (Slaney, SCOTT: A Semantically Guided Theorem Prover, Proc. IJCAI, 1993) we suggested semantic constraint as as an appropriate mechanism for guiding proof searches in propositional systems where the rule of inference is condensed detachment|a generalisation of Modus Ponens. Such constrained condensed detachment is closely analogous to semantic resolution...

OBJECTIVES To assess the frequency of retinal detachment following postcataract endophthalmitis and to evaluate the results of management of these detachments. METHODS Prospective data collected as part of the Endophthalmitis Vitrectomy Study were analyzed. The study was a randomized clinical trial testing the roles of vitrectomy and intravenous antibiotics in restoring vision in patients wit...

A mechanics-based mathematical model for retinal detachment is developed, incorporating an energy-based criterion for propagation. Retinas with and without central tears are considered and contraction of the vitreous and extension of its fibrils, along with a pressure difference across the retina, are taken as the stimuli for detachment propagation. In addition to the equations of motion, bound...

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...
