A single plant produces several different types of leaves or leaf-like organs during its life span. This phenomenon, which is termed heteroblasty, is an invariant feature of shoot development but is also regulated by environmental factors that affect the physiology of the plant. Invariant patterns of heteroblastic development reflect global changes in the developmental status of the shoot, such...

The present study demonstrates an efficient protocol for in vitro mass propagation of A. curassavica through direct as well as indirect regeneration. The effect of MS and L2 media supplemented with various concentrations and combinations of growth regulators has been studied. The growth regulators used include BAP and kinetin (cytokinins) and IAA, IBA, NAA and 2, 4-D (auxins). MS media proved b...

The primary goal of this paper is to discuss the state-of-the-art related to the structural identification (St-ID) of constructed systems, and to point out the most pressing needs for research and applications. As a subset of the system identification concept, St-ID aims to develop representative mathematical models of manufactured (mechanical) and constructed (civil) structural systems through...
