The ISO 18844 standard that is on the way defines a flare measurement method for a camera lens system similar to the measurement described in the older video standard IEC 61146. In addition it addresses the measurement of flare over the imaging field and also the measurement of devices that do not allow for adjusting the exposure like mobile devices. The paper provides an overview over the sour...

We discuss implications of a strong flare event observed in the Seyfert galaxy MCG-6-30-15 assuming that the emission is due to localized magnetic reconnection. We conduct detailed radiative transfer modeling of the reprocessed radiation for a primary source that is elevated above the disk. The model includes relativistic effects and Keplerian motion around the black hole. We show that for such...

AIMS To evaluate and compare prospectively the anterior chamber inflammatory response after phacoemulsification cataract surgery and after trabeculectomy with peripheral iridectomy. METHODS Anterior chamber inflammation was measured using the Kowa FM-500 laser flare meter in 131 patients undergoing trabeculectomy and 148 patients undergoing phacoemulsification cataract extraction with intraoc...

The rare phenomenon of ribbon-like hard X-ray (HXR) sources up to 100 keV found in the 2005 May 13 M8.0 flare observed with the Reuven Ramaty High Energy Solar Spectroscopic Imager provides detailed information on the spatial distribution of flare HXR emission. In this Letter, we further investigate the characteristics of HXR emission in this event using imaging spectroscopy, from which we obta...

BACKGROUND Pregnancy in patients with Wegener's granulamotosis (WG) is rare, and differential diagnosis of WG flare and preeclampsia is difficult. CASE A pregnant 35 year old with WG was referred with diagnosis of severe preeclampsia; caesarean section was performed. Intubation of the patient was difficult due to subglottic stenosis. Because of the clinical symptom, the case was considered pr...

Methods A retrospective chart review was conducted of all JIA patients who received IACI from 6/05 to 3/10, and had at least six months of follow-up. Data collected included demographic information, JIA subtype, date of injection and arthritis flare, type of joint injected and concomitant medications. Any joint that did not flare by the study end date in 9/10 was censored. Time to flare of arth...

Sunspots are concentrations of magnetic field visible on the solar surface (photosphere). It was considered implausible that solar flares, as resulted from magnetic reconnection in the tenuous corona, would cause a direct perturbation of the dense photosphere involving bulk motion. Here we report the sudden flare-induced rotation of a sunspot using the unprecedented spatiotemporal resolution of...

We compare quiescent and flare X-ray spectra of the RS CVn binary σ Gem obtained with the Chandra and XMMNewton grating spectrometers. We find that in addition to an overall 25% flux increase, which can be ascribed to variations in the system’s quiescence activity over the 15 months that passed between the observations, there is a hot plasma component of kTe >∼ 3 keV that arises with the flare....

We use Hinode observations to study coronal structures about to flare, based on their apparent footpoints as a guide to identification. The high resolution and excellent stability of the Hinode observations makes the identifications much more precise than those done with the soft X-ray telescope (SXT) on board Yohkoh. The physical conditions in the coronal structure about to flare are important...

The purpose of our study is to evaluate the effect of a single drop of latanoprost on the intraocular pressure and blood-aqueous barrier permeability in 8 patients with uveitis. The degree of inflammation was determined by the intensity of aqueous flare measured with a laser flare cell meter every 2 hours from 11:00 to 17:00 hours for 2 days. Intraocular pressure was measured at 11:00 and 17:00...
