Probing the (empirical) quantum structure embedded in the periodic table with an effective Bohr model

Química Nova, 2013
The atomic shell structure can be observed by inspecting the experimental periodic properties of the Periodic Table. The (quantum) shell structure emerges from these properties and in this way quantum mechanics can be explicitly shown considering the ...

A Simple Analytical Formulation for Periodic Orbits in Binary Stars [PDF]

, 2007
An analytical approximation to periodic orbits in the circular restricted three-body problem is provided. The formulation given in this work is based in calculations known from classical mechanics, but with the addition of the necessary terms to give a ...

A quasi-periodic oscillation in the blazar J1359+4011 [PDF]

, 2013
The OVRO 40-m telescope has been monitoring the 15 GHz radio flux density of over 1200 blazars since 2008. The 15 GHz light curve of the flat spectrum radio quasar J1359+4011 shows a strong and persistent quasi-periodic oscillation. The time-scale of the

From Glyph to Element Symbol – A Story of Names

CHIMIA, 2019
When I write the symbol Fe, all scientists know that I am talking about iron. Today's chemists use element symbols in formulae without thinking where they came from. This article looks at the history of element symbols and why we use the ones we

Application of a periodic table for the genetic code to influenza A/H3N2 virus [PDF]

, 2007
If biologists can utilize a table to have access to biological phenomena in the manner analogous to the periodic table for chemical elements, they may get hold of a directing post in life science.

The Genetic Code as a Periodic Table: Algebraic Aspects [PDF]

, 2000
The systematics of indices of physico-chemical properties of codons and amino acids across the genetic code are examined. Using a simple numerical labelling scheme for nucleic acid bases, data can be fitted as low-order polynomials of the 6 coordinates ...
