Global mean sea level rise estimated from satellite altimetry provides a strong constraint on climate variability and change and is expected to accelerate as the rates of both ocean warming and cryospheric mass loss increase over time. In stark contrast to this expectation however, current altimeter products show the rate of sea level rise to have decreased from the first to second decades of t...

BACKGROUND To evaluate disturbances in primary tooth eruption and their management with nonpharmacological remedies. METHODS In this nonrandomized clinical trial, 270 children aged between 8 and 36 months were selected and divided into 5 groups with 54 children initially enrolled in each group. The children were seen during an 8-day period during tooth eruption. At each appointment data were ...

*Correspondence: Antonio Costa, Istituto Nazionale di Geofisica e Vulcanologia, Via D. Creti 12, Bologna, Italy e-mail: [email protected] Super-eruptions, orders of magnitude larger than biggest eruptions experienced in historic times, have devastated wide areas by pyroclastic flows, covered continent-size areas by ash fallout, and injected large quantities of aerosols into the stratosph...

It is vital to detect volcanic plumes as soon as possible for volcanic hazard mitigation such as aviation safety and the life of residents. Himawari-8, the Japan Meteorological Agency’s (JMA’s) geostationary meteorological satellite, has high spatial resolution and sixteen observation bands including the 8.6 μm band to detect sulfur dioxide (SO2). Therefore, Ash RGB composite images (RED: brigh...

We report on a study of the changes in the vicinity of a disappearing solar filament (DSF) that occurred on 1993 April 30. The DSF was associated with a long duration X-ray event (LDE) observed by the GOES and Yohkoh spacecraft. A detailed analysis of the X-ray images obtained by the Yohkoh Soft Xray Telescope revealed that X-ray manifestations of the eruption were wide-spread: (i) X-ray enhanc...

a 7.5 year-old girl was seeking orthodontic treatment because of severe ectopic eruption of maxillary first permanent molars. it was a rare case that represented approximately horizontal view in panoramic radiograph. the severity of problem was high, but since the patient had maxillary deficiency, it was important to perform the treatment without extraction. treatment began with extraction of u...

Eruption cysts are benign cysts that appear on the mucosa of a tooth shortly before its eruption. They may disappear by themselves but if they hurt, bleed or are infected they may require surgical treatment to expose the tooth and drain the contents. Here we present 2 case reports of eruption cysts presenting with different chief complaint. The treatment included incising the eruption cyst and ...

AIM The aims of this study were firstly to determine the fate of unerupted permanent maxillary incisor teeth following supernumerary tooth removal and secondly to make recommendations regarding the management of such incisor teeth following supernumerary tooth extraction. STUDY DESIGN This is a retrospective study. METHODS Records of children attending the Departments of Paediatric Dentistr...

The aerosols injected into the lower stratosphere by the El ChichoH n and Mt. Pinatubo eruptions have increased the scattering of solar radiation back to space, thus, leading to a decrease in the solar radiation input to the Earth System. In this work we study the evolution in time of the volcanic e!ects of El ChichoH n's eruption using broadband solar radiation measured at two radiometric stat...

ABSTRACT The purpose of this study was to analyze the overjet and overbite behavior during eruption of the upper permanent incisors. Fourth-eight plaster casts of 16 patients from ages 6-13 years were appraised longitudinally. It was found that the overjet remains constant, starting at the eruption of the upper permanent central incisors until eruption of the upper permanent canine teeth, while...
