Eruption clouds in explosive volcanic eruptions are a kind of free boundary shear flow with very high Reynolds numbers (Re > 10), and their dynamics are governed by entrainment of ambient air into eruption clouds by turbulent mixing. We developed a numerical pseudo-gas model of an eruption cloud by employing three-dimensional coordinates, a high-order accuracy scheme, and a fine grid size in or...

Introduction: In most orthodontic patients, mandibular 3rd molars are in early stages of calcification, and prediction of eruption status would be difficult during the course of orthodontic treatment. The aim of this study was to evaluate the effect of first premolar extraction with moderate anchorage on angular changes of third mandibular molar after orthodontic treatment. Materials & Methods...

The first direct evidence that patterns of basaltic eruptive activity may be very similar on Io and Earth was seen on 26 November 1999, when the Solid State Imaging System on board the Galileo spacecraft obtained high-resolution images of a fissure eruption taking place in one of the calderas of the Tvashtar Catena complex. We analyzed the dynamics of the fissure eruption from the morphology of...

Aim To perform a systematic review and meta-analysis to establish if fever is associated with primary tooth eruption. Materials and methods Literature searches involved Pubmed, MEDLINE, Web of Science, Scopus and Cochrane. The potentially relevant studies had the full text analyzed. Only studies concerning fever during eruption period of primary tooth in humans were included. Papers in non-En...

Introduction Conclusions References

A total of 406 observations on dental eruption was obtained from 343 Japanese monkeys (Macaca fuscata) of known birthdays (Table 1). The order of the beginning of eruption was estimated as (M1, M1), (I1, I1), (I2, I2), (M2, M2), (PPPP), (C,, C'), (M3, M3) for male and (M1, M1), (I1, I1), (I2, I2), (M2, M2), (C,, P3, P3, C', P4, P4), (M3, M3) for female. Among 406 observations, 270 were used for...

INTRODUCTION Posterior open bite has several possible causes, including primary failure of eruption (PFE) that affects all teeth distal to the most mesial involved tooth, mechanical failure of eruption (MFE) (primarily ankylosis) that affects only the involved tooth or teeth, and soft-tissue interferences with eruption (other). METHODS Radiographs and other clinical records for 97 cases of fa...
