Abstract The current study was carried out in order to know the effect of plant metabolism, fertilizer type and michanical stress (soil compaction) factors on content root exudates mungbean Vigna radiate L. maize Zea mays from primary secondary metabolites. Root were collected their contents metabolites such as total sugars, proteins, phenols, flavonoids terpenoids, Hormons (gibberellic, abscis...

We consider information flow via physical transport of inscribed media through space and compare it to information flow via electromagnetic radiation. Somewhat counterintuitively for point to point links, physical transport of inscribed mass is often energetically more efficient by many orders of magnitude than electromagnetic broadcast. And perhaps more surprising, even in a broadcast setting ...

An invariant regulator field method is applied to the construction of vector current vertices in a dual resonance model. If it is not required that the regulators be fully conformally invariant, but only that they have the invariance required for duality, Gaussian factors can be eliminated consistently from both the elastic form factor and the deep inelastic structure functions. This method int...
