The effect of plant growth regulators (PGRs), gelling agents, sucrose and heat shock on shoot multiplication, shoot growth, rooting and subsequent survival of Chlorophytum borivilianum Sant. et Fernand was evaluated. Benzyladenine (BA) was found to be better cytokinin over kinetin (KIN) for shoot multiplication. Sucrose concentrations from 116–290 mM in the(More)
A series of benzo[d]imidazolyl chromeno[2,3-d]pyrimidnones were described. The key intermediate 2-cyano-N-(2-mercapto-1H-benzo[d]imidazol-5-yl)acetamide (3) is obtained by reacting 5-amino-2-mercaptobenzimidazole (1) with ethyl cyanoacetate (2). Compound 3 on reaction with substituted salicylaldehydes afforded(More)
The objective of present study was to improve the solubility, dissolution rate, micromeritic properties and bioavailability of aceclofenac (NSAID) by formulating its spherical agglomerates. They were prepared with different water soluble polymers (polyvinylpyrrolidone-K30, polyvinylpyrrolidone-K90 and sodium alginate) by using acetone-water-dichloromethane(More)
A series of novel chroman scaffold incorporate spirochromanone derivatives were synthesized from 2-hydroxyacetophenone and cyclic alkanones under microwave irradiation in good yields. Newly synthesized compounds were characterized by analytical and spectral (IR, proton nuclear magnetic resonance, 13C nuclear magnetic resonance, and mass spectrometry)(More)
In this paper a hopping robot motion with offset mass is discussed. A mathematical model has been considered and an efficient single layered neural network has been developed to suit to the dynamics of the hopping robot, which ensures guaranteed tracking performance leading to the stability of the otherwise unstable system. The neural network takes(More)
We theoretically study a low-threshold band-edge lasing in three-dimensional photonic crystals (PhCs) with a face-centered cubic lattice structure, using a complex-valued permittivity approach combined with the Korringa-Kohn-Rostoker method. We show that the lasing threshold at the low-frequency band edge is smaller than that at the high-frequency band edge(More)
