Direct Test of the Time-Independence of Fundamental Nuclear Constants Using the Oklo Natural Reactor

This list is not exhaustive, of course. In particular, the constants of strong interactions could be added to it. The \cosmological" quantities H and , which refer to the Universe as a whole, vary as it expands: they are decreasing at the rate of about 5 10 yr . On the other hand, the \laboratory" quantities 1)-6) are generally believed to be exactly constant. Milne [2] and Dirac [3] were the r...

Cosmological Variability of Fundamental Physical Constants

Testing cosmological variability of fundamental constants

One of the topical problems of contemporary physics is a possible variability of the fundamental constants. Here we consider possible variability of two dimensionless constants which are most important for calculation of atomic and molecular spectra (in particular, the X-ray ones): the fine-structure constant α = e/h̄c and the proton-toelectron mass ratio μ = mp/me. Values of the physical consta...

Antimalarial Activity of some Conjugated Arylhydrazones: Ab Initio Calculation of Nuclear Quadrupole Coupling Constants (NQCC)

“Malaria” is a life-threatening blood disease in tropical regions that spreads by the bite of the Anopheles mosquito. Antimalarial medications are designed to cure or prevent this infection, and prosperous achievements in this area mostly depend on the knowing the drug-receptor interactions and active sites of medicine. This improvement can be achieved through understanding the electronic struc...
