We calculate momentum transport from tearing fluctuations in a reversed field pinch with sheared flow, considering both the effect of a single tearing mode (through quasilinear theory and MHD computation) and multiple tearing modes (through nonlinear MHD computation). A single tearing mode transports momentum, via Maxwell and Reynolds stresses, more rapidly than classical viscous forces. Moreov...

Resistance to tearing plays a major role when evaluating the reliability of textiles used for example in protective clothing [1] and in composite materials [2]. Tearing in textile structures proceeds through the formation and propagation of a Del zone ahead of the crack. It arises from the stretching and slippage of longitudinal yarns along transverse yarns followed by the stretching and alignm...

PURPOSE To investigate the diagnostic effectiveness of dacryoscintigraphy in children with tearing; to evaluate tear clearance rate as a diagnostic factor of dacryoscintigraphy in children with tearing; and to analyze the results of treatment according to dacryoscintigraphic findings in children with tearing. METHODS Between January 2010 and April 2014, 176 eyes of 88 children with tearing (4...

Tracheal tearing occurs rarely and If not detect early, can be life-threatening and lead to death. Tracheal tearing has different risk factors and knowing these risk factors and proper management of the airway can reduce the appalling events. Treatment options include conservative management without surgical repair, surgical repair, and treatment with endoscopic intervention. Studies have discu...

This report summarises the cooperative research program on stable tearing between DSTO and CEAT. The main objective was to study the conditions under which aircraft materials fracture by stable tearing and to develop a predictive capability for the process under operational conditions. The experiments on both CCT and CT specimens were to assist in validation of numerical modelling. Tear bands w...

Tearing is not a benign secretory correlate of sadness or other emotional state, but a potent visual cue that adds meaning to human facial expression, the tear effect. Although tearing (lacrimation) provides ocular lubrication and is a response to irritation in many animals, emotional tearing may be unique to humans and does not develop until several months after birth. This study provides the ...

Abstract. The multi-scale interaction among the tearing mode and the drift wave is investigated using reduced MHD model including the electron viscosity. It is newly found that the fluctuating bootstrap current in the Ohm’s law gives rise to a new instability for the regime where the tearing mode is stable. The stability depends on the dissipations and kinetic effects. This result implies that ...

A 4-year-old tearing child with obstruction of the nasolacrimal duct was treated with dacryocystorhinostomy three years after naso-orbital injury. However, what appeared to be tearing persisted, and meningitis developed. Coronal CT scans demonstrated traumatic encephalocele of the posterior superior orbital roof. A chronic orbital cerebrospinal fluid (CSF) leak was diagnosed. To our knowledge n...

The effect of equilibrium velocity shear on the resistive tearing instability has been systematically studied, using the boundary layer approach. Both the "constant-f/!" tearing mode, which has a growth rate that scales as S -3/5, and the "nonconstant-f/!" tearing mode [a' (as) -1/3» 1], which has a growth rate that scales as S -1/3, are analyzed in the presence of flow. Here S is the usual rat...
