Abstract The Quaternary Tarosero volcano is situated in the East African Rift of northern Tanzania and mainly consists trachyte lavas some trachytic tuffs. In addition, there are minor occurrences extrusive basalts, andesites latites, as well peralkaline trachytes, olivine trachytes phonolites. Some phonolites contain interstitial eudialyte, making one few known for agpaitic rocks. This study i...

Orthodontic extrusion (OE), which is performed in many different clinical situations to move a tooth or its periodontal tissues coronally, is often associated with supracrestal fiberotomy and root planing (OEFRP) or followed by surgical crown lengthening. The OEFRP procedure must be carried out every 2 weeks during the entire extrusive orthodontic phase, and precise control of the technique its...

The Gruithuisen domes, situated on the western portion of the Imbrium basin rim, form three tall mountains (NW, Gamma, Delta) totaling ∼780 km 3 in volume. The shapes of the domes are significantly different from that of mare-type domes elsewhere on the Moon. We use data from the Lunar Reconnaissance Orbiter (LRO) and Kaguya missions (LRO Lunar Orbiter Laser Altimeter, Lunar Reconnaissance Orbi...

UNLABELLED The traumatized primary teeth have a great clinical significance because it not only have consequences on itself but also on its succedaneous developing permanent teeth due to its close anatomical relationship. The extent of severity is adjudged by the type of trauma and the age of the child at the time of trauma. For instance, avulsion and intrusive injuries present with high percen...

[1] Drilling during ODP Leg 209, dredging, and submersible dives have delineated an anomalous stretch of the Mid-Atlantic Ridge north and south of the 15 200N Fracture Zone. The seafloor here consists dominantly of mantle peridotite with gabbroic intrusions that in places is covered by a thin, discontinuous extrusive volcanic layer. Thick lithosphere (10–20 km) in this region inhibits magma fro...
