Blasius flow and heat transfer of fourth-grade fluid with slip

Applied Mathematics and Mechanics(English Edition) 2013年第12期34卷 1465-1480页

This investigation deals with the effects of slip, magnetic field, and non- Newtonian flow parameters on the flow and heat transfer of an incompressible, electrically conducting fourth-grade fluid past an infinite porous plate. The heat transfer analysis is carried out for two heating processes. The system of highly non-linear differential equations is solved by the shooting method with the fourth-order Runge-Kutta method for moderate values of the parameters. The effective Broyden technique is adopted in order to improve the initial guesses and to satisfy the boundary conditions at infinity. An exceptional cross-over is obtained in the velocity profile in the presence of slip. The fourth-grade fluid parameter is found to increase the momentum boundary layer thickness, whereas the slip parameter substantially decreases it. similarly, the non-Newtonian fluid parameters and the slip have opposite effects on the thermal boundary layer thickness.

When Exchange-rate Volatility Affects Trade

引用

中国对外贸易（英文版） 2013年第2期 26-27页

作者： Jér(o)me Héricourt sandra poncet Assistant Professor at EQUIPPE University of Lille Professor at the University of Paris Ⅰ and scientific advisor at CEPII

The increasing volatility of exchange rates after the fall of the Bretton Woods agreements has been a constant source of concern for both policymakers and *** countries fought hard in the 1980s to limit Us dollar fluctuation (one thinks of the Plaza and Louvre's agreements,respectively in 1985 and 1987),and some European countries took an even more radical decision by giving up their national currency for the euro in 1999.

Tuberculosis Meningitis Associated with poncet’s Disease: A Rare Case in a Young senegalese Patient

Case Reports in Clinical Medicine 2023年第7期12卷 223-226页

Described by Antonin poncet in 1897, poncet’s disease is a non-destructive (non-erosive) inflammatory arthritis secondary to a mycobacterial infection, without an identified infectious agent in the affected joints. Neuromeningeal localization of tuberculosis (TB) is rare but remains the most severe with hight mortality and permanent neurological damage. Association of poncet’s rheumatism and TB is rare, even less a neuromeningeal localization. We report here a case of optic nerve compression syndrome complicating tuberculous meningitis associated with poncet’s rheumatism characterized by a good outcome. This was an 18-year-old female with no reported pathological history, who was admitted for obnubilation. The symptoms started two weeks before her hospitalization and were marked by fever and headache. On admission, the examination revealed obnubilation, bilateral pyramidal deficit syndrome, right ptosis and areactive mydriasis predominating on the right, meningeal syndrome, and intense inflammatory polyarthralgia. The brain CT showed meningeal contrast enhancement with moderate dilatation of ventricles. GeneXpert MTB/rif in CsF was positive. Rheumatoid factors (latex and Waaler-Rose test) and anti-CCP antibodies were negative. Anti-nuclear, anti-native DNA and anti-NAs antibodies were negative. Ophthalmological examination revealed optic nerve compression syndrome associated with extrinsic and intrinsic oculomotor paralysis in the right eye. Orbito-encephalic MRI showed compression of the optic nerve, and hydrocephalus. Under antituberculosis treatment, we noticed disappearance of arthralgia in three weeks, regression of intracranial hypertension and improvement of vision.
