geometrical structure, nuclear magnetic resonance (n1,1it) chemical shielding tensors, and chemical shiftsof silicon and carbon nucler are investigated for twn infinite size zigzag and armchair single-walled siliconcarbide nanotabes (sicnts). geometrical structures of sients, sit bonds and bond angles of st and cvertices in both zigzag and armchair nanotubes, indicate that bond lengths are appr...

Nuclear Magnetic Resonance (NMR) is arguably both the best and the worst technology we have for the implementation of small quantum computers. Its strengths lie in the ease with which arbitrary unitary transformations can be implemented, and the great experimental simplicity arising from the low energy scale and long time scale of radio frequency transitions; its weaknesses lie in the difficult...

theoretical investigations on the characteristics of the nuclear quadrupole resonance and the influence of the magnetic effect on it have been carried out. the magnetic dipole effect on the quadrupole resonance for the two spins i and i with different values oft) and e has been studied. the energy levels and their transition probabilities are presented with their corresponding spectra. the firs...

Background Current strategies based on random selection of MII-oocytes to fertilize appear unsatisfactory in selecting the best number and the most vital oocytes to fertilize especially in poor responder women in which “chronological age” does not mismatch with “biological age”. The metabolomics- profiling approach, evaluating the final products of cell regulatory process (genome/transcriptome/...
