An exact solution in the stability of m. h. d. Couette flow

Autor: B. D. Hassard, G. S. S. Ludford, T. S. Chang

Publikováno v: Proceedings of the Royal Society of London. A. Mathematical and Physical Sciences. 327:269-278

The MHD stability problem for dissipative Couette flow in a narrow gap between corotating, conducting cylinders with an axial magnetic field is solved exactly. Results are presented for an arbitrary magnetic field; in particular, previous results on

On the instability of magnetohydrodynamic Couette flow via non-axisymmetric, oscillatory critical modes

Autor: T S Chang, G S S Ludford, B D Hassard

Publikováno v: Plasma Physics. 15:1235-1245

The onset of instability of MHD Couette flow due to non-axisymmetric, oscillatory disturbances is investigated. For counter-rotating cylinders, the existence is discovered of two threshold magnetic fields. Below the first threshold, non-axisymmetric,

Malignant melanoma of the maxillary sinus

Autor: A D, Hassard, S F, Boudreau

Publikováno v: Ear, nose,throat journal. 68(6)

A 40-year-old white man presented with a mucosal malignant melanoma of the left maxillary sinus two years after removal of a Clark III melanoma of the skin, posterior to the angle of mandible. The symptoms and the successful management of the disease

Ligation of the external carotid and anterior ethmoidal arteries for severe or unusual epistaxis resulting from facial fractures

Autor: A D, Hassard, D A, Kirkpatrick, F S, Wong

Publikováno v: Canadian journal of surgery. Journal canadien de chirurgie. 29(6)

From July 1980 to December 1983, 16 patients with severe posterior epistaxis were treated by arterial ligation. The procedure was successful in all. Two cases of life-threatening and unusual epistaxis resulting from maxillary fractures are presented

Benign thyroid disease and upper airway obstruction: case presentations, pathophysiology, and management

Autor: A D, Hassard, J G, Holland

Publikováno v: The Journal of otolaryngology. 11(2)

Investigations of three cases with large goiters and marked respiratory stridor showed different mechanisms of airflow limitations. This report describes the flow volume loop and Machida fiberoptic tracheoscopy as newer methods for evaluating the lar
