In this paper, we obtain the bound state energy eigenvalues and the corresponding eigenfunctions of the Schrdinger equation for the pseudo-Coulomb potential plus a new improved ring-shaped potential within the framework of cosmic string space–time using the generalized parametric Nikiforov–Uvarov ...
A representative collection of heat content plus zero-point energies deduced in the harmonic oscillator approximation suggests a number of simple additivity rules which allow ZPE+( H T H 0 ) to be related to structural features. Accurate evaluations are obtained for alkanes, alkenes, alkynes, ...
An overview of the study epigenetic phenomena and its importance in the field of plant growth and development is offered. Information on the cash prize and certificate given to the authors of the article is also presented.ingentaconnectBotany...
A return to the study of cell division over the last 10 plus years resulted in the discovery and analysis of a family of plant cell division inhibitors. The author's story emphasizes the importance of having motivated and creative scientists in the laboratory, but also recognizes the impact of...
CHEMILUMINESCENCE IN THE SYSTEM ATOMIC SODIUM PLUS ATOMIC HYDROGENWhen atomic sodium is diffused into a mixture of atomic and molecular hydrogen, a weak chemiluminescence is observed in the gas phase. Visible emission consists of the sodium D lines. The total intensity of the emission, ~5×10 11...
