Similarity analysis is made of the three dimensional incompressible laminar boundary layer flow of general class of non-Newtonian fluids. This work is an extension of previous analysis by Na and Hansen (1967), where the similarity solution of laminar three dimensional boundary layer equations of Power-law fluids was investigated. For the present flow… (More)
One hundred and thirty-three female patients admitted to a neurological ward were fully investigated for the presence of organic neurological disease, and assessed for psychiatric disorder and illness behaviour, using the Clinical Interview Schedule (CIS) and the Illness Behaviour Questionnaire (IBQ). The likelihood of the presenting symptoms being due to… (More)
There has been a great deal of interest in fractional differential equations. These equations arise in mathematical physics and engineering sciences. An attempt is made to solve some fractional differential Equation using the method of Laplace transforms. Some special cases with graphs have been discussed.
Present investigation is made of MHD of Rayleigh problem past semi-infinite plate impassively set into a motion, moves with constant velocity in non-Newtonian Sisko-fluid of infinite extend. The group theoretic technique is applied to transform present highly non-linear partial differential equation of boundary value type into non-linear ordinary… (More)
Nonlinear partial differential equations governing the motion of three-dimensional unsteady incompressible laminar boundary layer flow of non-Newtonian power-law fluid past a flat plate are treated. The governing equations containing three independent variables are reduced to the system of highly nonlinear ordinary differential equations, by two parameter… (More)
Steady two dimensional MHD stagnation point flow of a power law fluid over a stretching surface is investigated when the surface is stretched in its own plane with a velocity proportional to the distance from the stagnation point. The fluid impinges on the surface is considered orthogonally. Numerical and analytical solutions are obtained for different… (More)
In the present paper, using general group theoretic method, the similarity transformations are derived for steady, laminar, incompressible two dimensional natural convection boundary layer flow of non-Newtonian Sutterby fluid past a vertical isothermal plate. The application of a one-parameter deductive group transformation reduces the number of independent… (More)
Fifty-six consecutively admitted elderly (65 and over) patients with depression were assessed on mental, physical and social states. They were followed up and assessed at home one year later. A group of 24 depressed in-patients aged under 65 years admitted to the same ward during the same period was also assessed. Outcome was different for the two groups,… (More)
