Introdouction:Tooth eruption is recognized as an important aspect of human growth and development. It can be influenced by a number of factors, and it may reflect the general development of a child’s body. The purpose of this study was to determine the age at which the first primary tooth erupted and its relationship with height, weight and head circumference in 3-15-month children in the...

How filaments form and erupt are topics about which solar researchers have wondered since more than a century that still open to debate. We present observations of filament formation, its failed eruption, the associated flare (SOL2019-05-09T05:51) occurred in active region (AR) 12740 using data from SDO, STEREO-A, IRIS, NSO/GONG. AR was decaying formed by very disperse following polarity strong...

PURPOSE This study investigated the clinical process of the emergence phase of eruption of the primary dentition including length of time taken to erupt and the association between soft tissue changes and stages of eruption. METHODS Twenty-one children aged 6-24 months at commencement of the study were recruited from three suburban daycare centers in Melbourne, Australia. Daily oral examinati...

The solar active region NOAA 12887 produced a strong X1.0 flare on 2021 October 28, which exhibits X-shaped ribbons and circle-shaped erupting filament. To understand the eruption process with these characteristics, we conducted data-constrained magnetohydrodynamics simulation using nonlinear force-free field of about an hour before as initial condition. Our reproduces filament observed in Ha i...

Earth is no stranger to volcanism. Since proto-Earth and crustal formation, volcanoes have provided pathways for degassing and cooling of our planet’s interior. Volcanism played an important role in the formation of the early atmosphere, oceans and continents, and was likely a necessary component for the development of life. Throughout our species brief history, innumerable volcanoes have erupt...

Introduction Ectopic eruption of a first permanent molar" is a developmental disturbance in which the mesially directed path of eruption results in resorption of the second primary molar. Pulver and Bjerklin found no specific etiologic factor for ectopic eruption, but noted that it appeared more commonly among siblings^ and was not specific to any quadrant. Different modes of treatment have bee...

Crustal-stored magma reservoirs contain exsolved volatiles which accumulate in the reservoir roof, exerting a buoyancy force on crust. This produces surface uplift and sudden loss of through eruption results syn-eruptive subsidence. Here, we present three-dimensional, visco-elasto-plastic, numerical modeling quantify ground deformation arising from growth release volatile reservoir. Deformation...

Using a Potential Field Source Surface model (PFSS), we study magnetic field overlying erupted filaments in solar active regions. The filaments studied here were reported to experience a kink instability or a torus instability. The torus instability leads to a full eruption, while the kink instability leads to a full eruption or a failed eruption. It is found that for full eruption the field de...
