The Galileo spacecraft has been periodically monitoring volcanic activity on Io since June 1996, making it possible to chart the evolution of individual eruptions. We present results of coanalysis of Near-Infrared Mapping Spectrometer (NIMS) and solidstate imaging (SSI) data of eruptions at Pele and Pillan, especially from a particularly illuminating data set consisting of mutually constraining...

[1] Northern temperate and high-latitude wetlands are a major source of the greenhouse gas methane (CH4). Here, we estimate the sensitivity in the strength of this source to the effects of large Icelandic volcanic eruptions such as the Laki eruption of 1783–1784. We applied spatially explicit modeled sulfate aerosol and S deposition fields from a Laki eruption simulation to a climate-sensitive ...

AIM The aim of this report is to present a clinical case of impaction of a maxillary left central incisor in a mixed dentition caused by the presence of an odontoma as well as a review of the pertinent dental literature. BACKGROUND Knowledge of the normal tooth eruption patterns is essential for the identification and appropriate treatment of deviations in eruption that may endanger physiolog...

I N T R O D U C T I O N A N D P R O B L E M M O T I V A T I O N Old Faithful, the most famous geyser in Yellowstone National Park, is known for the regularity and predictability of its eruptions. Predictability, however, has many gradations. Although it is possible to predict an eruption after observing the previo...

The ideal helical kink instability of a force-free coronal magnetic flux rope, anchored in the photosphere, is studied as a model for solar eruptions. Using the flux rope model of Titov & Démoulin (1999) as the initial condition in MHD simulations, both the development of helical shape and the rise profile of a confined (or failed) filament eruption (on 2002 May 27) are reproduced in excellent ...

Sir, Perioral dermatitis is an uncommon facial eruption of women and children presenting as tiny papules and pustules often in a perioral distribution.[1] It is now more correctly referred to as “periorificial dermatitis” as it frequently involves perinasal and periocular skin. Granulomatous periorificial dermatitis (GPD) is a distinct facial eruption in prepubertal children characterized by a ...

Etofenamate is a non-steroidal anti-inflammatory drug (NSAID). Clinical findings caused by etofenamate are uncommon. Allergic contact dermatitis is the most common cutaneous reaction reported. But petechial eruption due to etofenamate had not been reported yet. This report concerns an 11-year old male with petechial eruption after application of topical etofenamate. Physicians need to be aware ...

We use a ballistic model to simulate the particle number densities in plumes on Io as a function of eruption rates and particle size distributions. Comparison of the simulated apparent brightness variations within plumes with the properties of actual plumes allows constraints to be put on the particle sizes present and the eruption rates. We find evidence for lower eruption rates, by a factor o...

Midline diastema is a space between the central incisors. Although physiologic transitory maxillary midline diastema is observed in children during eruption of maxillary anterior teeth in most cases, it is self-corrected after eruption of maxillary canines. However, midline diastema unrelated to the eruption of teeth has been observed owing to various etiologic factors. Treatment to align the c...

Forced eruption can be performed in teeth with caries, fracture, resorption or perforation in the cervical third of the root or isolated teeth with one- or two-walled vertical periodontal defects. The purpose of this case report is to introduce an innovative orthodontic appliance which enables forced eruption. This appliance is easy to fabricate, cost-effective and very effective in forced erup...
