In this paper, the artificial generation of elementary catastrophe optics having odd codimensions K = 1, 3 and 5 such as the Fold, the Swallowtail and the Wigwam diffraction caustics is investigated theoretically. It is shown that the integral catastrophes with odd polynomials phase functions can be reduced to the well-known Airy-Hardy cosine integrals. In this connection, the caustic functions of the Fold, Swallowtail and Wigwam ...

An exhaustive literature survey on the secondary
metabolites of widely distributed Prunella vulgaris L. species has been carried out.
Triterpenoids, sterols, phenylpropanoids, flavonoids, coumarins, fatty acids, volatile
oils and carbohydrates along with some other compounds, have been reported from
this species. Many of these compounds have been found to possess significant biological
properties, including antihypertensive activity, antica ...
