Constructive Study of Modulational Instability in Higher Order Korteweg-de Vries Equations

Our present study is devoted to the constructive study of the modulational instability for the Korteweg-de Vries (KdV)-family of equations u t + s u p u x + u x x x (here s = ± 1 and p > 0 is an arbitrary integer). For deducing the conditions of the instability, we first computed the nonlinear corrections to the frequency of the Stokes wave and then explored the coefficients of the corresponding modified nonlinear Schrödinger equations, thus deducing explicit expressions for the instability growth rate, maximum of the increment and the boundaries of the instability interval. A brief discussion of the results, open questions and further research directions completes the paper.

The effect of a homoeopathic complex (Candidum, Helonias, Mercurius solubilis and Sepia officinalis) on growth and germ tube production of Candida albicans

The aim of the study was to establish the effect of a Helonias complex on the growth of Candida albicans in vitro in terms of growth rate, maximum specific growth rate, latent period before maximum specific growth rate and percentage germ tube production so as to establish the area of action of homoeopathic remedies
