Anisotropic Geodesic Fluid Spheres in General Relativity
It is shown that unlike the perfect fluid case, anisotropic fluids (principal stresses unequal) may be geodesic, without this implying the vanishing of (spatial) pressure gradients. Then the condition of vanishing four acceleration is integrated in non-comoving coordinates. The resulting models are necessarily dynamic, and the mass function is expressed in terms of the fluid velocity as measure...
متن کاملRelativistic anisotropic charged fluid spheres with varying cosmological con- stant
Static spherically symmetric anisotropic source has been studied for the EinsteinMaxwell field equations assuming the erstwhile cosmological constant Λ to be a space-variable scalar, viz., Λ = Λ(r). Two cases are examined out of which one reduces to isotropic sphere. The solutions thus obtained are shown to be electromagnetic in origin as a particular case. It is also shown that the generally u...
متن کامل219-225 Karmarkar LAJP 1626:Karmarkar
Fenofibrate is more effective drug as compared to other fibrates. But low bioavailability of it is due to its poor aqueous solubility. The purpose of present study was to improve fenofibrate dissolution through its formulation into liquisolid tablets and then to investigate in vitro performance of prepared liquisolid systems. By use of this technique, liquid medications such as solutions or sus...
متن کاملBending-Unbending Analysis of Anisotropic Sheet under Plane Strain Condition
The mechanical behavior of cold rolled sheets is significantly related to residual stresses that arise from bending and unbending processes. Measurement of residual stresses is mostly limited to surface measurement techniques. Experimental determination of stress variation through thickness is difficult and time-consuming. This paper presents a closed form solution for residual stresses, in whi...
متن کاملNonlocal Equation of State in Anisotropic Static Fluid Spheres in General Relativity
We present a general method for obtaining static anisotropic spherically symmetric solutions, starting from known density profiles and satisfying a nonlocal equation of state. This equation of state describes, at a given point, the components of the corresponding energymomentum tensor not only as a function at that point, but as a functional throughout the enclosed configuration. In order to es...
