[1] Starting soon after the 1997 eruption at Okmok volcano and continuing until the start of the 2008 eruption, magma accumulated in a storage zone centered ∼3.5 km beneath the caldera floor at a rate that varied with time. A Mogi‐type point pressure source or finite sphere with a radius of 1 km provides an adequate fit to the deformation field portrayed in time‐sequential interferometric synth...

On 2005 September 13 a filament eruption accompanied by a halo CME occurred in the most flare-productive active region NOAA 10808 in Solar Cycle 23. Using multi-wavelength observations before the filament eruption on Sep. 13th, we investigate the processes leading to the catastrophic eruption. We find that the filament slowly ascended at a speed of 0.1km s over two days before the eruption. Dur...

The purpose of this study was to elucidate a possible association between ectopic first molar eruption causing root resorption on the distal root of the primary maxillary second molar, and ectopic canine eruption causing root resorption on the permanent maxillary incisors. The subjects consisted of 30 patients, 22 females and eight males in the age range 8.3-15.0 years in whom root resorption o...

OBJECTIVE: To evaluate the influence of the initial vertical position of impacted maxillary incisor on spontaneous eruption frequency and its timing after surgical removal of the supernumerary tooth. Material And Methods: 44 patients with unilateral impaction of maxillary permanent central incisor with an average age of 10.5 years were studied for spontaneous eruption of impacted tooth. Orthopa...

The introduction of ribavirin to hepatitis C combination therapy with pegylated interferon (PEG-IFN)-α2a has improved sustained responses, but it has been accompanied by an increased incidence of cutaneous side effects. Most cases of drug eruption caused by ribavirin and PEG-IFN-α2 or IFN-α combination therapy were not severe and we progressed without discontinuation of the antiviral treatment....

Polymorphic light eruption is one of the few dermatological diseases in which some antioxidants have been said to be reduced in both the epidermis and the blood. This study measured the hydrosoluble antioxidant capacity in the serum of patients with polymorphic light eruption, using a commercially available kit. All patients were tested in winter, in order to avoid the influence of exposure to ...

Magma is transported in brittle rock through dikes and sills. This movement may be accompanied by the release of seismic energy that can be tracked from the Earth’s surface. Locating dikes and deciphering their dynamics is therefore of prime importance in understanding and potentially forecasting volcanic eruptions. The Seismic Amplitude Ratio Analysis (SARA) method aims to track melt propagati...

Aims. We report observation of a large-amplitude filament oscillation followed by an eruption. This is used to probe the pre-eruption condition and the trigger mechanism of solar eruptions. Methods. We used the EUV images from the Extreme-Ultraviolet Imaging Telescope on board SOHO satellite and the Hα images from the Flare Monitoring Telescope at Hida Observatory. The observed event is a polar...

Background The eruption pattern of temporary and permanent teeth are fairly constant with the growing age. So the age determination of an individual by examination of teeth is one of the accepted methods in legal system. A review of the literature shows there are differences in eruption pattern between different populations mainly due to variations in the constitutions and environment, so highl...
