Explosive volcanic eruptions radiate seismic waves as a consequence of pressure and shear traction changes within the conduit/chamber system. Kinematic source inversions utilize these to determine equivalent force moment tensor sources, but relation eruptive processes is often ambiguous nonunique. In this work, we provide an alternative, forward modeling approach calculate equivalents model con...

Background and aims. Predicting the teeth eruption time is a valuable tool in pediatric dentistry since it can affects scheduling dental and orthodontic treatments. This study investigated the relationship between the eruption time of first primary and permanent teeth and the variation in the eruption time considering socioeconomic status (SES) in a 9-year population- based cohort study. Materi...

PURPOSE The purpose of this project was to establish median eruption ages of primary teeth and evaluate eruption differences between contralateral teeth by gender, ethnicity, and household income. Data was derived from a caries study of preschool children. METHODS A total of 4,277 white (non-Hispanic) and Hispanic preschool children from Arizona were visually examined for caries and tooth eru...

A broad range of variation exists in the normal eruption times of primary and permanent teeth in humans. However, normality is usually associated with bilateral symmetry. Furthermore, cases where eruption time is grossly beyond the extremes of normalcy may be considered to represent a pathological state [1]. Radiography plays an important part in determining the normality of tooth eruption with...

In 1975, E. R. Robinson conducted the hallmark study of the behavior of classical nova light curves before eruption, and this work has now become part of the standard knowledge of novae. He made three points; that 5 out of 11 novae showed pre-eruption rises in the years before eruption, that one nova (V446 Her) showed drastic changes in the variability across eruptions, and that all but one of ...

introduction: failure of teeth to erupt from gingival tissues at usual developmental time is called delayed tooth eruption (dte). delayed tooth eruption lead to prolonged fixed orthodontic treatment and its eventual complications. the purpose of the present study was to evaluate the effect of laser-assisted (808 nm) surgical uncovering, on the tooth emergence and orthodontic treatment of dte. m...

third molar eruption is an unpredictable event. occasionally, mandibular third molars undergo angular changes in young adults. this rotational drift is of unknown etiology, is not predictable and may facilitate the eruption or may make the impaction worse. a rare case is presented with severe rotational drift of a mesioangularly impacted mandibular third molar.

Background: Pregnancy-specific dermatoses represent a group of pruritic skin diseases unique to pregnancy and the most common types are polymorphic eruption of pregnancy and pemphigoid gestationis. It is difficult to obtain a histopathological diagnosis for polymorphic eruption of pregnancy and pemphigoid gestationis in the lack of immunofluorescence because of their similar clinical presentati...
