in vitro multiple shoot regeneration of solanum nigrum l., an indian medicinal plant was accomplished on ms medium utilizing shoot tip and nodal explants. direct multiple shoots differentiated within 6 weeks when explants were cultured on ms medium containing bap (1.0-5.0 mg/l) and kin (1.0-5.0 mg/l) individually. among various concentrations of cytokinins tested, maximum number of multiple sho...

S U M M A R Y With seismic interferometry a virtual source can be created inside a medium, assuming a receiver is present at the position of the virtual source. Here we discuss a method that creates a virtual source inside a medium from reflection data, without needing a receiver inside the medium. Apart from the reflection data, an estimate of the direct arrivals is required. However, no expli...

This paper describes an improved model for multiple building diffraction modeling based on the uniform theory of diffraction (UTD). A well-known problem in conventional uniform theory of diffraction (CUTD) is multiple-edge transition zone diffraction. Here, higher order diffracted fields are used in order to improve the result; hence, we use higher order diffraction coefficients to improve a hy...

We calculate the spectrum of gluons sourced by branching an energetic quark in presence inhomogeneous QCD medium, focusing on soft radiation limit. take into account multiple interactions between partons and matter, treating transverse variations its parameters within a gradient expansion. Thus, we derive general form medium induced up to first order gradients, consider simplifying limits. In p...
