چکیده
A class of new solutions for Einstein’s field equations, by choosing the ansatz e?(r)=1+kr2R21+r2R2 metric potential, are obtained under Karmarkar condition. It is found that a number pulsars like 4U 1820-30, PSR J1903+327, 1608-52, Vela X-1, J1614-2230, Cen X-3 can be accomodated in this model. We have displayed nature physical parameters and energy conditions throughout distribution using numerical graphical methods particular pulsar 1820-30 solution satisfies all requirements.

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 کاملPulsating Relativistic Stars
Pulsating stars have given important information in classical astronomy and are still an active research field, e.g. asteroseismology or helioseismology. By studying the rich oscillation stellar spectra, optical astronomy makes predictions for the stellar equations of state (EOS), the evolutionary age of the stars, and in the case of Cepheids one can make exact predictions for the distance of t...
متن کاملInstabilities of Relativistic Stars
Recent developments on the rotational instabilities of relativistic stars are reviewed. The article provides an account of the theory of stellar instabilities with emphasis on the rotational ones. Special attention is being paid to the study of these instabilities in the general relativistic regime. Issues such as the existence relativistic r-modes, the existence of a continuous spectrum and th...

The present work deals with the comparison of in vitro dissolution profiles of fenofibrate liquisolid tablet formulations with those of marketed fenofibrate tablets, and the application of statistical methods to evaluate each method for its usefulness. The methods used to study dissolution profile comparison include Model independent method (Similarity factor, f2); Model dependent methods (Zero...
متن کاملSpacetime modes of relativistic stars
The problem of relativistic stellar pulsations is studied in a somewhat ad hoc approximation that ignores all fluid motions. This Inverse Cowling Approximation (ICA) is motivated by two observations: 1) For highly damped (w-mode) oscillations the fluid plays very little role. 2) If the fluid motion is neglected the problem for polar oscillation modes becomes similar to that for axial modes. Usi...
