Expansion-free self-gravitating dust dissipative fluids

Abstract: The present study deals with the spherically symmetric distributions of dust dissipative fluids with a central vacuum cavity, evolving under the condition of vanishing of expansion scalar. The work is based on two aspects—on the one hand the description of model in terms of structures scalars emerging in the orthogonal splitting of Riemann tensor. Secondly, to obtain the solutions of dynamical equations under some special cases and assumption on implicit function of variables. The solutions here discussed, model the evolution of the vacuum cavity of fluid distribution, thereby showing the potential of expansion free motion.

In Vitro Multiplication of Paedaria foetida L — A Rare Medicinal Plant

Abstract: Paedaria foetida L, which has great medicinal value is facing danger of extinction. For its conservation, in vitro multiplication may prove one of the best techniques. Micropropagation of P. foetida has been achieved through the culture of nodal explants. The explants produced shoots on MS medium with 0.8% agar. This medium, however, caused high degree of browning of the explants and death of sprouted shoots. Agar free liquid MS medium with polyvinylpyrrolidone (PVP) proved better. Maximum shoot proliferation, free from callus and vitrification but with poor rooting could be obtained in liquid MS medium with PVP (0.8%), NAA (0.5 mg l−1) and BA (2.0 mg l−1). The best rooting occurred on semisolid MS medium containing 0.8% agar and 0.5 mg l−1 IBA.
