The deformation of sheet-like igneous intrusions in multiple orientations can give detailed insights into the kinematics ductile flow shear zones. Using Torrisdale Vein Complex northern Scottish Caledonides as a case study, we examine relationships between folded and boudinaged pegmatitic deformed by strike-slip dominated shear. Within zone, that trend clockwise adjacent regional foliation were...

OBJECTIVES/HYPOTHESIS Preferred treatment of oral/plunging ranulas remains controversial. We present our experience with ranulas at the University of North Carolina (UNC) and review the literature. METHODS Retrospective review. From 1990 to 2007, 16 oral ranulas and 10 plunging ranulas were treated at UNC. Combining the UNC series with the literature identified 864 cases for review. An online...

OBJECTIVE This study was designed to evaluate the diagnosis and surgical treatment of the plunging ranula in children. STUDY DESIGN A retrospective study of 129 pediatric patients with a clinical diagnosis of plunging ranula was conducted. All children underwent clinical assessment and fine needle aspiration cytology. Cytologic diagnosis was considered to be definitive, and radiologic investi...

• Stock indexes have dual fractal structure which is consistent with previous studies. • The return distribution of emerging markets shows abnormal dual power-law exponents. • External shock of a crisis affects different markets at distinct stages. a b s t r a c t We investigate minute indexes of stock markets in 10 countries during financial crashes by dividing them into several stages accordi...

This paper numerically investigates the self-propelled swimming of a flexible filament driven by coupled pitching and plunging motions at leading edge. The influences bending rigidity some actuation parameters (including phase offset between plunging, amplitudes motions) on performance are explored. It is found that with increasing rigidity, style gradually transits from undulatory mode to osci...

A t the impact of a plunging liquid jet with a receiving pool, air bubbles may be entrained if the impact velocity exceeds a critical velocity. New experiments were performed in a two-dimensional plunging jet. The ̄ ow conditions near the inception of air entrainment were investigated. Two mechanisms of air entrainment were visualized at low jet velocities: by elongated air cavity and by foam bu...

Based on Navier-Stokes equations and structural and flight dynamic equations of motion, dynamic responses in vertical discrete gust flow perturbation are investigated for a supersonic transport model. A tightly coupled method was developed by the subiteration between aerodynamic equations and dynamic equations of motion. First, under the assumption of rigid-body and single freedom of motion in ...

Laboratory experiment is conducted to investigate the long waves generated by time-varying breakpoint. We focus our attention on the variation of plunging point as well as the variation of breaking point. The results show that free long waves (BFLW) are really generated by the variation of the starting point of wave set-up which coincide with the plunging point and that the BFLW observed can be...

BACKGROUND A ranula is a mucocele arising in the floor of the mouth, secondary to the obstruction of the salivary ducts of the sublingual glands. “Plunging” ranulas present as masses involving the submandibular triangle or other neck spaces, secondary to herniation of a portion of the sublingual gland through dehiscences in the mylohyoid muscle. The cervical component of a ranula is a pseudocys...
